OBJECTIVE: To assess the value of endometrial thickness measurement as a
test for endometrial cancer in postmenopausal women with vaginal
bleeding (symptomatic women). DATA SOURCES: We conducted a literature
search using the MEDLINE database from 1991 to 1997, and the key words
"vaginal ultrasonography" and "endometrial thickness measurement." The
review was limited to original research reports written in English,
concerning symptomatic women having vaginal ultrasonography before a
diagnostic test and not receiving tamoxifen. STUDY SELECTION: A total of
48 studies were identified. A questionnaire was sent to the
corresponding author of each paper requesting supplementary information.
Data were included in our analysis if the corresponding author was able
to supply information on the median endometrial thickness in unaffected
symptomatic women and the endometrial thickness values in affected
women. Nine studies were thus included in our meta-analysis,
representing 3483 women without endometrial cancer and 330 women with
endometrial cancer. TABULATION, INTEGRATION, AND RESULTS: The median
endometrial thickness in women with endometrial cancer was 3.7 times
that in unaffected women at the same center, and with the same
menopausal status and same hormone replacement therapy use category. The
detection rate was 63% (95% confidence interval 58, 69) for a 10%
false-positive rate, or 96% (95% confidence interval 94, 98) for a 50%
false-positive rate. CONCLUSION: Endometrial thickness measurement in
symptomatic women does not reduce the need for invasive diagnostic
testing because 4% of the endometrial cancers would still be missed with
a false-positive rate as high as 50%.

CASE: A 67-year-old multiparous woman received 20mg tamoxifen daily for
four years after surgical treatment of breast cancer. She presented with
vaginal bleeding. Uterine curettage revealed a uterine MMT with
heterologous elements. She was treated surgically with adjuvant
radiotherapy. Tumor cells were found to be estrogen receptor negative
and progesterone receptor positive. Uterine MMT may be linked to long
term use of tamoxifen. A mechanism in developing MMT other than estrogen
receptor pathway may be possible.

Expression of cyclin A in endometrial adenocarcinoma and its correlation
with proliferative activity and clinicopathological variables.
SO - J Cancer Res Clin Oncol 2002 Jun;128(6):307-12
AD - Department of Obstetrics and Gynecology, Kitasato Medical Institute
Hospital, 6-100 Arai, Kitamoto, Saitama 364-8501, Japan.
PURPOSE: Cyclin A is known as an S- and G2-M phase regulatory protein
and its abnormal expression has been reportedly implicated in cellular
proliferation. This study was designed to investigate the correlation of
cyclin A expression with tumorigenesis of the endometrium and
clinicopathological variables. METHODS: Immunohistochemical staining
using labeled streptavidin-biotin complex was performed on
formalin-fixed, paraffin-embedded tissue of normal endometrium (15
cases), endometrial hyperplasia (23 cases), and endometrial
adenocarcinoma (endometrioid type) (112 cases). RESULTS:
Immunohistochemistry showed that the nuclei of the cells were positive
for cyclin A. In normal endometrium, only proliferative phase was
focally positive for cyclin A. Cyclin A was also positive for
endometrial hyperplasia. Its expression in hyperplasia was significantly
more frequent than that of proliferative phase and less than that of
endometrioid adenocarcinoma. The labeling index (LI) of cyclin A in
endometrioid adenocarcinoma was 16.3+/-6.9 in well-differentiated,
18.3+/-8.8 in moderately differentiated, and 30.2+/-11.8 in poorly
differentiated adenocarcinoma, respectively. Cyclin A expression
increased significantly more in high histological grades. The area of
squamous metaplasia in endometrioid adenocarcinoma was negative for
cyclin A. The LI of cyclin A was positively correlated with that of
Ki-67 and cyclin-dependent kinase 2. Cyclin A expression was
significantly associated with carcinoma without coexisting endometrial
hyperplasia and lymphovascular space involvement (LVSI), but not with
FIGO stage, myometrial invasion, lymph node metastasis, estrogen
receptor, progesterone receptor, and menopause as well as recurrence.
CONCLUSIONS: Cyclin A expression was involved in the progression to
malignancy of the endometrium and was correlated with proliferative
activity and prognostic features including histological grade, without
coexisting endometrial hyperplasia and LVSI.

SO - Scand J Public Health 2002;30(1):12-9
AD - Department of Community Medicine, Lund University, Malmo University
Hospital, Malmo, Sweden. Bo.Hedblad@smi.mas.lu.se
AIM: The goal of this study was to evaluate the incidence of myocardial
infarction, cancer and death in relation to use of hormone replacement
therapy (HRT). METHODS: Nine years' follow up of an urban cohort of
peri-/postmenopausal women was undertaken. Local and national registers
were used for retrieval of events. RESULTS: The incidence of myocardial
infarction per 1.000 person-years in users and non-users was 0.61
(5/962) and 2.20 (92/4759) respectively, adjusted relative risk (RR)
0.37; 95% confidence interval 0.15-0.90. Rates of mortality from
cardiovascular disease and cancer were 0.36 and 1.10, p= 0.058, and 2.60
and 2.09, p=0.360 respectively. In terms of all-cause mortality the
adjusted RR was 1.02; 0.69-1.52, incidence of cancer 1.28; 1.01-1.64,
breast cancer 1.52; 1.01-2.28 and endometrial cancer 3.61; 1.54-8.46.
CONCLUSIONS: Women affirming use of HRT had a lower incidence of
myocardial infarction. Further studies are needed to assess whether the
absence of effect on total mortality may be accounted for by an
increased cancer risk.

Advances in the management of endometrial adenocarcinoma. A review.

Endometrial adenocarcinoma is the most common and curable gynecologic
neoplasm; the five-year survival for women with surgical stage I disease
ranges from 83% to 93%; stage II, 73%; stage III, 52%; and stage IV,
27%. The absence of an asymptomatic latency phase amenable to detection
through screening and the already excellent cure rates seen with
early-stage disease have precluded the need for endometrial cancer
screening programs. Adenocarcinomas constitute 97% of endometrial
cancers, with endometrioid the most common histologic subtype. Two
different pathways of endometrial carcinogenesis exist. One arises in a
background of estrogen excess, giving rise to atypical hyperplasia as
the malignant precursor of the more common endometrioid adenocarcinomas.
The use of oral contraceptives has consistently been shown to decrease
the risk of developing endometrial carcinoma via this pathway, with 12
months or more of continuous use decreasing the lifetime risk by 40-50%.
The alternate pathway of endometrial carcinogenesis represents malignant
transformation of atrophic endometrium and proceeds through endometrial
intraepithelial carcinoma as the malignant precursor of the more
virulent serous papillary and clear cell endometrial adenocarcinomas.
The staging of endometrial cancer (according to the International
Federation of Obstetrics and Gynecology) is surgical. Recent studies
suggest a therapeutic benefit associated with extensive retroperitoneal
lymph node evaluation to determine the disease extent and thereby more
effectively direct potentially life-saving adjuvant therapy. Adjuvant
radiation therapy, known to have survival benefit in advanced-stage
disease, may also have survival benefit in intermediate-risk surgical
stage I disease on the basis of results recently released from a
Gynecologic Oncology Group study. The use of radiation therapy, systemic
chemotherapy and hormonal therapy, alone or in combination, is
recommended for primary advanced and recurrent disease.

Up-regulation of cyclooxygenase-2 expression and prostaglandin synthesis
in endometrial stromal cells by malignant endometrial epithelial cells.
A paracrine effect mediated by prostaglandin E2 and nuclear factor-kappa
B.

We investigated the regulation of prostaglandin production in normal
endometrial stromal cells (ESC) by malignant endometrial epithelial
cells. We found that cyclooxygenase (COX)-2 mRNA and protein levels and
prostaglandin (PG)E(2) production in ESC were significantly increased by
Ishikawa malignant endometrial epithelial cell conditioned medium
(MECM). By using transient transfection assays, we found that the
-360/-218-bp region of the COX-2 promoter gene was critical for MECM
induction of promoter activity. This MECM-responsive region contained a
variant nuclear factor (NF)-kappa B site at -222 to -213 that, when
mutated, completely abolished COX-2 promoter activation by MECM.
Employing electrophoretic mobility shift assays, we further demonstrated
that binding of NF-kappa B p65 to this NF-kappa B-binding site is, in
part, responsible for the COX-2 promoter activation by MECM. To
investigate further the potential effects of MECM on COX-2 mRNA
stability, ESC were treated with MECM in the absence or presence of
actinomycin D, a general transcription inhibitor. We found that MECM
significantly increased COX-2 mRNA stability. Intriguingly, we found
that PGE(2) was one of the major factors in MECM, which was responsible
for up-regulating COX-2 expression in ESC. ECC-1 and HEC-1A malignant
endometrial epithelial cell lines also produced significantly increased
quantities of PGE(2). In conclusion, malignant endometrial epithelial
cells secrete PGE(2) that induces COX-2 expression in normal endometrial
stromal cells in a paracrine fashion through activation of transcription
and stabilization of COX-2 mRNA.

Cigarette smoking and the risk of endometrial cancer.
SO - Lancet Oncol 2002 Aug;3(8):470-80
AD - Department of Epidemiology and Social Medicine at the Albert Einstein
College of Medicine, Bronx, NY 10461, USA. pterry@aecom.yu.edu
Epidemiological studies have shown that cigarette smoking is associated
with a reduced risk of endometrial cancer, in contrast to the increased
risks observed with many other non-respiratory-tract cancers, including
those of the bladder, pancreas, and cervix uteri. Some studies of
endometrial cancer suggest that the inverse association with smoking is
limited to certain groups of women, such as those who are postmenopausal
or those taking hormone-replacement therapy. The biological mechanisms
that might underlie this association remain unclear, although several
have been proposed, including an antioestrogenic effect of cigarette
smoking on circulating oestrogen concentrations, a reduction in relative
bodyweight, and an earlier age at menopause. We have examined the
evidence for an association between cigarette smoking and risk of
endometrial cancer, including studies related to the proposed biological
mechanisms.

Cervical cytology and immunohistochemical features in endometrial
adenocarcinoma simulating microglandular hyperplasia. A case report.
SO - Acta Cytol 2000 Jul-Aug;44(4):661-6
AD - Department of Pathology, Medical College of Wisconsin, Milwaukee 53226,
USA. vshidham@mcw.edu
BACKGROUND: The histology of a few cases of adenocarcinoma simulating
cervical microglandular hyperplasia (MGH-AdCa) has been reported.
However, the cytologic features of MGH-AdCa in cervical smears and the
immunohistochemical profile have not been described. CASE: A 73-year-old
female presented with vaginal bleeding. The cervical Pap smear was
initially interpreted by the cytotechnologist as "reactive endocervical
cells" and was referred for cytopathologist review. The final
interpretation was atypical glandular cells of undetermined significance
(AGUS), probably neoplastic. Endometrial biopsy and total abdominal
hysterectomy with bilateral salpingo-oophorectomy showed International
Federation of Gynecologists and Obstetricians grade 1 endometrial
carcinoma. The superficial component of the tumor resembled cervical
microglandular hyperplasia (MGH); the deeper component had an
endometrioid pattern. The Pap smear predominantly showed a glandular
component with features of MGH. However, the presence of scattered
single cells with hyperchromatic nuclei, one to three nucleoli, easily
detectable mitotic figures, randomly scattered apoptotic bodies and
focal, watery diathesis suggested a neoplastic process.
Immunohistochemistry was studied on paraffin sections. In addition to
other markers, the tumor cells were immunoreactive for carcinoembryonic
antigen (CEA). CONCLUSION: Although the cervical Pap smear in this case
had an MGH-like pattern, some features were atypical enough to suggest a
diagnosis of AGUS, probably neoplastic. CEA immunoreactivity of MGH-AdCa
could also help to differentiate it from MGH.

A binary architectural grading system for uterine endometrial
endometrioid carcinoma has superior reproducibility compared with FIGO
grading and identifies subsets of advance-stage tumors with favorable
and unfavorable prognosis.
SO - Am J Surg Pathol 2000 Sep;24(9):1201-8
AD - Department of Pathology, The Johns Hopkins University School of
Medicine, Baltimore, Maryland, USA.
The International Federation of Gynecology and Obstetrics (FIGO) grading
of uterine endometrial endometrioid carcinoma requires evaluation of
histologic features that can be difficult to assess, including
recognition of small amounts of solid growth, distinction of squamous
from nonsquamous solid growth, and assessment of degree of nuclear
atypia. The authors describe a novel, binary architectural grading
system that uses low-magnification assessment of amount of solid growth,
pattern of invasion, and presence of necrosis to divide endometrioid
carcinomas into low- and high-grade tumors. The authors analyzed its
performance for predicting prognosis and with respect to intra- and
interobserver reproducibility. A total of 141 endometrioid carcinomas
from hysterectomy specimens were graded according to the FIGO system,
nuclear grading, and the binary architectural system. A tumor was
classified as high grade if at least two of the following three criteria
were present: (1) more than 50% solid growth (without distinction of
squamous from nonsquamous epithelium); (2) a diffusely infiltrative,
rather than expansive, growth pattern; and (3) tumor cell necrosis. For
tumors that were confined to the endometrium, only percent solid growth
and necrosis were evaluated, and those with both solid growth of more
than 50% and necrosis were considered high grade. All tumors were graded
independently by three pathologists on two separate occasions. Both
inter- and intraobserver agreement using the binary grading system
(kappa = 0.65 and 0.79) were superior compared with FIGO (kappa = 0.55
and 0.67) and nuclear grading (kappa = 0.22 and 0.41). The binary
grading system stratified patients into three distinct prognostic
groups. Patients with stage I low-grade tumors with invasion confined to
the inner half of the myometrium (stages IA and IB) had a 100% 5-year
survival rate. Patients with low-grade tumors that invaded beyond the
outer half of the myometrium (stage IC and stages II-IV) and those with
high-grade tumors with invasion confined to the myometrium (stages IB
and IC) had a 5-year survival rate of 67% to 76%. In striking contrast
to patients with advance-stage low-grade tumors, patients with
advance-stage high-grade tumors had a 26% 5-year survival rate. This
binary grading system has advantages over FIGO and nuclear grading that
permit greater interobserver and intraobserver reproducibility and
should be tested in other studies of endometrial endometrioid carcinomas
to validate its reproducibility and use for segregating patients into
different prognostic groups.

Molecular pathology of endometrial hyperplasia and carcinoma.
SO - Hum Pathol 2001 Jun;32(6):569-77

Autonomous University of Barcelona, Barcelona, Spain.
Four different genetic abnormalities may occur in endometrioid
adenocarcinomas of the endometrium (mircosatellite instability and
mutations in the PTEN, k-RAS and beta-catenin genes), whereas
nonendometrioid carcinomas of the endometrium often have p53 mutations
and loss of heterozygosity on several chromosomes. Occasionally, a
nonendometrioid carcinoma may develop as a result of dedifferentiation
of a preexisting endometrioid carcinoma; in such a case, the tumor
exhibits overlapping clinical, morphologic, immunohistochemical, and
molecular features of the 2 types. The insaturation of microsatellite
instability in endometrial carcinogenesis seems to occur late in the
transition from complex hyperplasia to carcinoma, and it is preceded by
progressive inactivation of MLH-1 by promoter hypermethylation.
Moreover, the endometrioid adenocarcinomas that exhibit microsatellite
instability show a stepwise progressive accumulation of secondary
mutations in oncogenes and tumor suppressor genes that contain
short-tandem repeats in their coding sequences. Mutations in the PTEN
and k-RAS genes are also frequent in endometrioid adenocarcinomas of the
endometrium, particularly in the tumors that exhibit microsatellite
instability, whereas beta-catenin mutations do not seem to be associated
with such a phenomenon. Copyright 2001 by W.B. Saunders Company.

Aggressive endometrial carcinoma in a breast cancer patient treated with
tamoxifen with normal transvaginal ultrasonography. Case report.
SO - Eur J Gynaecol Oncol 2002;23(1):25-8
AD - Data Centre, Jules Bordet Institute, Brussels, Belgium.
Since tamoxifen therapy can induce endometrial disorders, surveillance
schemes of women taking tamoxifen have been recommended. Transvaginal
ultrasonography is a very sensitive test and therefore is often
performed as a first-line screening test. We described a very atypical
case of a high stage, high grade endometrial cancer associated with
tamoxifen in a 64-year-old woman with a past history of breast cancer.
This women was assessed yearly by ultrasonography and Pap smear. The
cancer developed on a very thin endometrium and transvaginal
ultrasonography failed to detect it. The patient remained asymptomatic
up to the diagnosis. Normal endometrial cells in the Pap smear test were
the only signs associated with this cancer. Surveillance strategies and
significance of endometrial cells on the Pap smear are reviewed. In
conclusion, TVUS can fail to detect cancers if the endometrial lining is
not enlarged. In case of normal endometrial cells in the Pap smear, a
careful evaluation should be performed.

Comparison of two procedures for sentinel lymph node detection in
patients with endometrial cancer: a pilot study.
SO - Eur J Gynaecol Oncol 2002;23(1):53-7
AD - Department of Obstetrics and Gynaecology, Endoscopic Training Centre,
Baby Friendly Hospital, Kladno, Czech Republic.
OBJECTIVE: The purpose of this study was to assess the feasibility and
contribution of two intraoperative procedures of lymphatic mapping and
sentinel node detection using a blue dye in surgically-staged patients
with early stage endometrial cancer. METHODS AND MATERIALS: In 25 cases
of endometrial cancer, patent blue-V was injected into the subserosal
myometrium (13 cases, SM group) or cervico-subserosal myometrium (12
cases, CSM group) during a surgical staging procedure.
Laparoscopically-assisted vaginal hysterectomy and pelvic
lymphadenectomy were completed successfully in 23 women out of 24
laparoscopically-staged patients (95.8%). One patient with FIGO stage
IIa was indicated for a radical abdominal surgery. RESULTS: A deposition
of the blue dye was found in at least one pelvic lymph node (LN) in
eight out of 13 cases (61.5%) in the SM group compared with ten out of
12 cases (83.3%) in the CSM group (p = 0.378). The mean number of
dye-colored LN (DCLN) was 1.15 (SM group) and 2.5 (CSM group),
respectively (p = 0.05). The rate of DCLN/LN was 15/188 (SM group)
versus 30/190. respectively (p = 0.03). An uptake of the blue bye was
observed in a total of 45 out of 388 LN. CONCLUSION: An intraoperative
combination of cervico-subserosal myometrium application of the blue dye
allows successful detection (83.3%) of sentinel LN in patients with
endometrial cancer. Comparing SM and CSM groups the statistical
significant difference was found in the DCLN/LN rate and mean number of
sentinel lymph nodes (p = 0.03, p = 0.05, respectively). Clinical
validity of this surgical procedure must be assessed prospectively.

Evaluation of morbidity after external radiotherapy and intracavitary
brachytherapy in 771 patients with carcinoma of the uterine cervix or
endometrium.
SO - Eur J Gynaecol Oncol 2002;23(1):58-62
AD - Ege University, Faculty of Medicine, Department of Radiation Oncology,
Izmir, Turkey.
PURPOSE: The aim of the present study was to evaluate early and late
radiation morbidity and to assess the factors influencing morbidity in
patients with cervical or endometrial cancer treated by a combination of
external radiotherapy (ERT) and intracavitary brachytherapy (IBRT).
MATERIALS AND METHODS: Early and late radiation morbidity were evaluated
retrospectively using RTOG/EORTC criteria and Franco-Italian glossary in
Four hundred and seven patients (52.8%) had endometrial carcinoma and
364 (47.2%) had carcinoma of the cervix. One hundred and fifty-four
patients with cervical carcinoma were inoperable. In patients with
endometrial carcinoma total doses at the vagina, bladder and rectum were
60.36 Gy, 56.2 Gy and 55.6 Gy respectively. Biologically equivalent
doses (BED) for the same points were 79.35, 68.63 and 67.37,
respectively for early effects and 123.67, 97.65 and 94.85, respectively
for late effects. One hundred and sixty-nine patients (41.5%) developed
acute morbidity, grade I and II bladder morbidity being the most common
type and 85 patients (20.9%) developed late morbidity, grade I and II
vaginal morbidity being the most common type. No grade IV morbidity was
recorded. Total doses at the vagina, bladder and rectum in operated
cervix cancer patients were 60.51 Gy, 56.53 Gy and 55.67 Gy,
respectively. BED for the same points were 79.77, 69.36 and 67.52,
respectively for early effects and 124.74, 99.3 and 95.17, respectively
for late effects. Eighty patients (38.1%) developed early morbidity.
Grade I and II bladder morbidity was the most common type. Sixty-five
patients (30.9%) developed late morbidity, vaginal morbidity being the
most common type. Total doses at the vagina, bladder and rectum in
inoperable patients were 70.92 Gy, 66.71 Gy and 62.38 Gy, respectively.
BED for the same points were 97.43, 89.64 and 81.63, respectively for
early effects and 159.3, 143.16 and 126.56, respectively for late
effects. Sixty patients (39%) developed acute morbidity which was grade
I or II bladder morbidity in 95%. Ninety-five patients (61.7%) developed
late morbidity which was grade I-III vaginal morbidity in 94%.
CONCLUSION: Patients with cervical or endometrial cancer can be treated
safely by a combination of ERT and IBRT. However the patients should be
assessed before, during and after treatment and at every period of
follow-up using a standard and well-defined system in order to define
and predict the morbidity rate.

Immunohistochemical investigation of p-53, C-NEU and EGFR expression in
HPV-related epidermoid endometrial carcinoma.
SO - Eur J Gynaecol Oncol 2002;23(1):70-1
AD - Pathology Department, Areteion Hospital, Athens University, Greece.
Epidermoid carcinoma (PSCC) of the endometrium is a rare form of
endometrial cancer that constitutes about 0.1% of all malignant
epithelial tumors of the uterus. The diagnosis of PSCC is based on
strict criteria and is made in the absence of a glandular component of
the tumor. Squamous cell carcinoma of the endometrium should enter the
differential diagnosis in postmenopausal patients in the presence of
atypical squamous cells in the uterine curettage, while the cervical
biopsies are negative for malignancy. The presence of HPV should be
investigated as well, so that its pathogenetic relation is clarified.
While no significant relation was found to p-53, C-NEU and EGFR
expression this investigation must be continued because. HPV may
interact with tumor suppressor genes.

OBJECTIVES: To provide an update for nurses involved in the care of
women at risk or being treated for endometrial cancer. DATA SOURCES:
Review articles, research reports, and medical and nursing text-books.
CONCLUSIONS: Endometrial cancer is the most common gynecologic
malignancy. Although most women with endometrial cancer present with
early stage disease and have an excellent chance of cure, approximately
6,600 women in the United States are expected to die from the disease in
2002. Treatment of patients with advanced or recurrent disease remains
challenging, with no proven best standard of treatment. IMPLICATIONS FOR
NURSING PRACTICE: Nursing plays an important role in prevention and
early detection of endometrial cancer, patient education, patient care,
and rehabilitation.

To evaluate the therapeutic benefit of lymphadenectomy and adjuvant
therapy, in particular chemotherapy, we retrospectively analysed
survival rates and patterns of recurrence of endometrioid adenocarcinoma
in 106 patients who underwent surgery including retroperitoneal
lymphadenectomy. Adjuvant chemotherapy was administered to 46 patients
(42 received a platinum-based regimen) and pelvic irradiation to 12. The
5-year survival rate of 23 patients with lymph node metastasis was worse
than that of patients without lymph node metastasis (60% vs 96%,
P<0.0001). Recurrence was observed in 14 patients (10 patients with
chemotherapy, two with irradiation, and two without adjuvant therapy);
the first site of recurrence was in distant sites in 12 patients;
recurrence in the pelvic sidewall or exclusively in lymph nodes was not
observed. The 5-year survival rate of 18 patients with lymph node
metastasis treated with chemotherapy, was 61% including all 14 with
macroscopically positive nodes and all nine with paraaortic metastasis.
Of seven patients with bulky positives nodes, three patients with bulky
paraaortic nodes died of the disease, three of the four patients with
bulky pelvic but without bulky paraaortic nodes had no recurrence. In
summary, lymphadenectomy may afford a survival benefit via the debulking
of macroscopically positive nodes, and the predominance of distant
recurrences suggests that chemotherapy is a suitable choice as an
adjuvant therapy in endometrial carcinoma after lymphadenectomy.

The role of chemotherapy for metastatic endometrial carcinoma is
palliation, although modest response can be achieved because of
development of chemotherapy. The response rate is 31-56% of conventional
CAP therapy and 33-81% of AP therapy. However these chemotherapeutic
regimen did not prolong the survival. Recently, a randomized trial of
TAP therapy (TXL 160 mg/m2 3 h, day 2, ADM 45 mg/m2, day 1, CDDP 50
mg/m2 day 1) versus AP therapy (ADM 60 mg/m2, CDDP 50 mg/m2) was
reported. The response and survival of TAP is superior to that of AP.
Taxane will be key drugs for chemotherapy of endometrial cancer in the
future.

Inguinal lymph node metastasis as the presenting symptom of endometrial
cancer: a case report.
SO - Anticancer Res 2002 Jul-Aug;22(4):2531-2

Austria. scholzhs@kfunigraz.ac.at
BACKGROUND: Less than 5% of patients with endometrial cancer present
with stage IV disease and among these inguinal metastasis is rare. CASE:
A 54-year-old patient presented with a palpable, 5x3 cm right inguinal
mass. Histopathology showed bulky lymph nodes with mucinous
adenocarcinoma. Hysteroscopy and curettage revealed well-differentiated
endometrioid adenocarcinoma. Total abdominal hysterectomy, bilateral
salpingo-oophorectomy, omentectomy and systematic pelvic and paraaortic
lymphadenectomy were performed. Final histopathology showed an
endometrioid adenocarcinoma with infiltration of the inner half of the
myometrium. Metastases up to 2.3 cm in diameter were found in 11 out of
76 pelvic, and 17 out of 51 paraaortic lymph node CONCLUSION: Inguinal
lymph node metastasis can occur in patients with endometrial cancer and
may be the presenting symptom in patients with occult endometrial
disease.

Association of hypoxia-inducible factors 1alpha and 2alpha with
activated angiogenic pathways and prognosis in patients with endometrial
carcinoma.
SO - Cancer 2002 Sep 1;95(5):1055-63
AD - Department of Pathology, Democritus University of Thrace,
Alexandroupolis, Greece.
BACKGROUND: Hypoxia-inducible factor 1alpha (HIF-1alpha) and HIF-2alpha
are essential regulatory proteins for the adaptation of tumor cells to
hypoxia, and they stimulate angiogenesis through activation of the
vascular endothelial growth factor (VEGF) gene. METHODS: HIF-1alpha and
HIF-2alpha proteins were studied immunohistochemically in a group of 81
patients with Stage I endometrial adenocarcinoma of the endometrioid
cell type. The results were correlated with intratumoral angiogenesis,
the expression of the angiogenic factors VEGF and thymidine
phosphorylase (TP), and the VEGF/receptor (VEGF/KDR) complex. Relations
also were sought with estrogen receptor (ER) and progesterone receptor
(PR), with the apoptosis-related proteins bcl-2 and p53, with several
histopathologic parameters, and with patient prognosis. In addition, a
sample of 25 normal endometria at various phases of the menstrual cycle
was studied for the presence of HIF-1alpha and HIF-2alpha. RESULTS:
HIF-1alpha expression was detected in 49% of endometrial carcinomas. The
expression was cytoplasmic or mixed nuclear/cytoplasmic. HIF-1alpha
expression was associated with up-regulation of the VEGF pathway and
with increased standard microvessel density (sMVD) and activated
VEGF/KDR microvessel density (aMVD). It also was associated with a poor
prognosis in both univariate and multivariate analyses. HIF-2alpha
protein showed a pattern of expression similar to the pattern seen in
HIF-1alpha, but expression of HIF-2alpha protein occurred in only 17% of
endometrial carcinomas, and it was associated with increased TP
reactivity. There also was a relation of HIF-1alpha expression with
well-differentiated endometrial neoplasms, and there was a marginal
association of HIF-1alpha and HIF-2alpha with ER expression. With
reference to normally cycling tissues, HIF-1alpha nuclear/cytoplasmic
expression was particularly strong in the samples of early proliferative
phase endometrium compared with HIF-2alpha protein expression, which
showed a constant reaction throughout the menstrual cycle. CONCLUSIONS:
The up-regulation of HIF-1alpha and, to a lesser extent, of HIF-2alpha
is a common event in Stage I endometrial adenocarcinomas. In these
tumors, HIF-1alpha expression is related to increased angiogenesis,
through activation of the VEGF angiogenic pathway, and to an unfavorable
prognosis. HIF-2alpha accumulation is associated with increased
expression of the angiogenic factor TP. Copyright 2002 American Cancer

Regulation of keratinocyte growth factor expression in human
endometrium: implications for hormonal carcinogenesis.

Estrogen is thought to be an important etiologic agent in endometrial
and breast cancers. However, the mechanism or mechanisms by which
estrogen acts as a hormonal carcinogen are not well understood. We
hypothesize that in response to chronic exposure to estrogens, human
endometrial stromal fibroblasts (ESF) produce factors that facilitate
neoplastic transformation in epithelial cells. To test this hypothesis,
we assessed the regulation of keratinocyte growth factor (KGF) mRNA and
protein in ESF by interleukin-1 (IL-1) and diethylstilbestrol (DES).
Short-term treatments with IL-1 but not with DES increased the abundance
of KGF mRNA in ESF. However, chronic treatment with DES significantly
increased KGF mRNA levels and protein production. KGF protein in medium
conditioned by ESF chronically treated with 1 nM DES reached
concentrations of approximately 100 ng/mL. At this concentration, KGF
increased endometrial epithelial cell numbers fourfold and enhanced
anchorage independence tenfold. These results suggest that KGF may play
a role in hormonal carcinogenesis by mediating estrogen-induced changes
in the interactions between stromal and epithelial cells. To address the
potential role of nuclear transcription factor kappa B (NF-kappaB) in
regulating KGF expression, we determined the effect of increased
expression of its inhibitor, IkappaBalpha, on KGF mRNA and protein
levels. Transfection with IkappaBalpha blocked induction of KGF
expression by IL-1 but had no effect on the increase in KGF mRNA caused
by chronic treatment with DES. These results suggest that IL-1 exerts
its effects on KGF by an NF-kappaB-mediated pathway but that chronic
treatment with DES stimulates KGF expression by some other mechanism.

Frameshift mutations at mononucleotide repeats in caspase-5 and other
target genes in endometrial and gastrointestinal cancer of the
microsatellite mutator phenotype.

The majority of tumors from hereditary nonpolyposis colorectal cancer
families and a subset of unselected gastrointestinal and endometrial
tumors exhibit a microsatellite mutator phenotype (MMP) that leads to
the accumulation of hundreds of thousands of clonal mutations in simple
repeat sequences. The mutated genes with positive or negative roles in
cell growth or survival in aneuploid gastrointestinal cancer (e.g., APC,
K-ras, and p53) are less frequently mutated in near-diploid MMP
gastrointestinal tumors. These tumors accumulate mutations in other
genes, such as DNA mismatch repair hMSH3 and hMSH6, transforming growth
factor-beta type II receptor, and BAX. All these genes carry, within
their coding sequences, mononucleotide repeats that are preferred
targets for the MMP. Endometrial carcinoma is the most common type of
extracolonic neoplasia in the hereditary nonpolyposis colorectal cancer
syndrome, but the spectrum of its target cancer genes is not well
characterized. Here, we report that endometrial cancer of the MMP also
accumulates mutations in genes that are typically mutated in
gastrointestinal cancer of the mutator pathway, including BAX (55%),
hMSH3 (28%), and hMSH6 (17%). We also report the detection of frameshift
mutations in caspase-5, a member of the caspase family of proteases that
has an (A)10 repeat within its coding region, in MMP tumors of the
endometrium, colon, and stomach (28, 62, and 44%, respectively). We
therefore suggest caspase-5 as a new target gene in the microsatellite
mutator pathway for cancer.

Microsatellite instability (MSI) in human carcinoma DNA is a
characteristic phenotype observed in hereditary non-polyposis colorectal
cancer and also in some human sporadic cancers including multiple
primary carcinomas. In this study, we analyzed mutations in the hCHK1,
E2F4, hMSH3, and hMSH6 genes in MSI+ human cancers arising in
colorectum, stomach and endometrium. The E2F4 and hMSH3 genes were
mutated in all tumor types. Interestingly, the hMSH6 gene was mutated in
colorectal and gastric cancers but not in endometrial cancer; this is
similar to the TGFbetaRII gene. It is notable that the mutation status
of the secondary mutators, hMSH3 and hMSH6, did not influence
slippage-related frameshift mutations in genes harboring simple
tandem-repeats, which suggests that the MSI phenotype may be affected
mainly by abnormalities in the primary mutator genes, not by the
secondary mutator genes. No mutations were observed in the cell cycle
checkpoint gene hCHK1; mutations of this gene are thought to have a
limited role, if any, in at least the tumor types analyzed in this
study.

The objective was to review the English-language literature regarding
the utility of adjuvant radiation therapy following surgery for
endometrial adenocarcinoma. An OVID software (Ovid Technologies, Inc.,
New York, NY) search of Medline articles from 1975 to 2001 was conducted
using the keywords "endometrial neoplasm," "surgery," and "radiation
therapy." The papers were assessed with regard to (a) extent of surgical
staging (b) type of adjuvant radiotherapy utilized: external vs.
brachytherapy vs. combination therapy; and (c) whether the patients were
treated as part of prospective trial or reported as a descriptive series
reflecting an institution's practice pattern. Survival rates are
excellent for patients with early stage disease treated in either
paradigm of extended-surgical staging with more restricted use of the
adjuvant therapy or simple hysterectomy bilateral salpingoophorectomy
with more frequent use of adjuvant radiotherapy. All three
prospective-randomized trials (PRCT) have shown an improvement in local
control but no overall survival benefit for the entire accrued group.
All three PRCTs have shown a higher risk of disease recurrence in older
patients or those with grade 3 histology or deep invasion. Each suggests
there may be a survival benefit for the subset of patients with such
high-risk features, but at present there is no prospective data that
demonstrates adjuvant radiotherapy will improve the overall survival for
the highest-risk subset of older patients with high-grade deeply
invasive disease.

With increasing lifespan and decreased incidence of uterine cervical
cancer, the importance of the proper and early diagnosis of endometrial
cancer has become a demand to gynecology. The objective of the present
study is to evaluate the effectiveness of gynecologic diagnostic tools
in detection of endometrial cancer in early stage. The patients (72)
involved in the study, after giving their informed consent, were
investigated by transvaginal ultrasound and subsequent vacuum
endometrial sampling in office settings. Whenever the histology
examination of endometrial vacuum sampling showed hyperplasia or
carcinoma, it was reassured by sampling with dilatation and curettage.
The analysis of sonography and histology results showed that in 4 cases
(5.6%) endometrial hyperplasia and in two cases (2.8%) endometrial
adenocarcinoma were present. Also analyzed were sensitivity,
specificity, positive and negative predictive values for histology
results and for sonographic findings. These results show that
transvaginal ultrasound is a reliable method for screening for
endometrial carcinoma. Moreover, in the case of pathologic endometrial
change suspected by ultrasound, the combination of vacuum endometrial
sampling with ultrasound examination can yield firm diagnosis in office
settings, saving cost and time in early diagnosis of endometrial cancer.

The objective of this study was to determine the prognostic significance
of common immunohistochemical pathologic risk factors in fully staged

adenocarcinomas were considered high risk for recurrence because of deep
myometrial invasion and poor differentiation (stage IC, G3), cervical
metastasis (stage II), ovarian metastasis (stage IIIA) or lymph node
metastasis (stage IIIC). All patients underwent complete
