In this study, we examined the expression of cyclins, cyclin dependent
kinase (CDKs) and CDK inhibitors by immunohistochemical analysis in 20
normal mucosa, 42 epithelial dysplasia (ED), and 117 oral squamous cell
carcinoma. Neither Cyclin D1 nor CDK2 were detectable in normal tissue
and ED. Their presence, however, was detectable in squamous cell
carcinoma (SCCs) (Cyclin D1, 35.9%; CDK2, 66.7%). Cyclin E was
detectable in 57.1% of severe ED and 62.8% of SCCs. For the CDK
inhibitors, these proteins were detectable in all normal mucosa and most
of the mild and moderate ED. For severe ED, expression of these proteins
was not observed in some cases (p12(DOC-1), 14.3%; p16(INK4A), 28.6%;
p27(KIP1), 7.1%). For SCCs, the expression of p12(DOC-1) was lost in
71.8%, p16(INK4A) in 69.2% and p27(KIP1) in 35.9%. These results suggest
that elevated expression of cyclin D1, cyclin E, CDK2 and loss of
p12(DOC-1), p16(INK4A) and p27(KIP1) may contribute to the multistep
nature of oral carcinogenesis.

To investigate the chromosomal imbalances that occur in oral carcinoma
associated primarily with betel use and their clinical implications, we
performed chromosomal analysis using comparative genomic hybridization
on 47 patients with this disease. The most common gains of chromosome
arms were 8q, 9q and 11q, and the most frequent losses were of
chromosomal arms 3p and 4q. The clinical parameters significantly
associated with the numbers of chromosomal imbalances per tumor were the
age of the patients and nodal metastasis. The preliminary findings of a
lower incidence of loss of 4q and gain of 8q in betel-associated tumors
compared to non-betel-associated tumors might provide insight into the
carcinogenic effect of betel. Deletion of 3p and the gain of 11q
alterations were more prevalent in carcinomas with lymph node metastasis
than in node-negative tumors, indicating possible loci for metastasis
suppressor or metastasis enhancing genes, respectively. Losses of 3p and
4q and gain of 9q were associated with poor outcome for the patients.
These data demonstrated that the frequent aberrations in 4q and 9q sites
can be used as novel prognostic predictors.

The prognostic and clinicopathologic significance of cyclin D1 and Ki-67
expressions was studied in oral squamous cell carcinomas. We performed
an immunohistochemical study to determine the level of expression of
cyclin D1 and Ki-67 labelling index in tumor specimens obtained from 35
patients, of whom 14 died as a result of recurrent disease, and 20 were
free of recurrence at the end of the follow-up period. Overexpression of
cyclin D1 was significantly associated with regional lymph node
metastases (P=0.00005) and advanced tumor stage (P=0.0007). The relative
risk for nodal metastases in the cases that overexpressed cyclin D1 was
2.6. The Ki-67 labelling index was significantly (P=0.001) higher in
tumors with poor histologic grade of differentiation. Our results showed
that cyclin D1 is a useful prognostic factor, and suggested it could be
a marker to help determine the appropriate treatment for patients with
oral squamous cell carcinoma. Cyclin D1 and Ki-67 overexpression were
positively correlated.

The aim of this study was to evaluate the role of supraomohyoid neck
dissection (SOHND) in oral carcinoma patients with clinically negative
carcinomas and clinically negative lymph nodes in the neck underwent
elective SOHND in Chang Gung Memorial Hospital, Taiwan. Thirty-seven
patients had postoperative radiotherapy.Thirty-four (24.3%) patients had
occult cervical metastases. The overall regional control rates were
93.4% vs. 85.3% for pathologically negative vs positive nodes,
respectively, with or without adjuvant radiotherapy. Adjuvant
radiotherapy significantly improved ipsilateral regional control
(P=0.012) in patients with occult cervical metastases but not in
patients with negative neck disease. (P=1.0) SOHND is both a diagnostic
and therapeutic procedure in patients with negative neck disease. Its
therapeutic role in patients with positive neck disease remains
controversial. Postoperative radiotherapy significantly improve
ipsilateral neck control in patients with occult cervical metastasis.

OBJECTIVE: To evaluate the use of a combined lateral temporal fossa and
intraoral approach to resect palatal carcinomas and the use of a
temporalis myofascial flap for reconstruction. DESIGN: Retrospective
chart review of a case series. SETTING: Tertiary university referral
hospital. PATIENTS: Sixteen patients underwent a combined approach for
resection of palatal carcinoma; 5 of the 16 were edentulous. Six types
of tumors were treated: adenoid cystic carcinoma (3 patients), low-grade
mucoepidermoid carcinoma (5 patients), squamous cell carcinoma (3
patients), polymorphous low-grade adenocarcinoma (2 patients),
osteosarcoma (1 patient), ameloblastoma (1 patient), and hyalinizing
clear cell carcinoma (1 patient). MAIN OUTCOME MEASURES: The
postoperative diet, velum competence, flap viability, complications, and
survival. RESULTS: Fifteen (94%) of 16 patients were able to resume
their preoperative diets. No velopharyngeal insufficiency was
encountered. All flaps survived and none required repeated surgical
intervention. Five patients developed serous otitis media and 2 patients
required flap revision secondary to posterior choanal obstruction. One
patient died of complications unrelated to the procedure. CONCLUSIONS: A
combined intraoral and lateral temporal fossa approach allows for (1) en
bloc resection of palatal malignancies along with resection of involved
pterygoid muscles, (2) isolation and resection of descending palatine
nerves and the proximal second division of the trigeminal nerve, and (3)
primary reconstruction of the palatal defect by means of the temporalis
muscle rotated into the operative defect. This method is especially
useful in treating patients with perineural spread of palatal carcinoma,
and in those who are edentulous.

OBJECTIVE: Laser monotherapy for squamous cell carcinoma of the mobile
tongue treated with CO2 laser was carried out on 18 cases between 1979
and 1997. MATERIALS AND METHODS: Three cases recurred after laser
surgery. As a subsequent therapy, radiotherapy was performed on two of
them and laser surgery was repeated on the remaining one. No recurrences
were found in the two patients who died from other diseases after laser
surgery. RESULTS: The cure rate of primary tumors was 83.3%. One patient
had subsequent metastasis after laser surgery. The rate of recurrence
and subsequent metastasis was compared between a group of patients
treated with laser surgery and a group treated with radiotherapy
(interstitial implant). No differences were found in the rate of
recurrence between the two groups. While 22 of 52 patients had a
subsequent metastasis in the group treated with interstitial implant,
only one patient had it in the group treated with laser surgery. There
was a statistical difference between these two groups (p < 0.01).

This report describes a complete response to a chemoradiotherapy regimen
in a child with an advanced and unresectable squamous cell carcinoma of
the tongue. An 8-year-old girl had stage 4 squamous cell carcinoma of
the tongue (T4N2M0), causing severe trismus and dysphagia. She received
hyperfractionated external beam radiotherapy (total 74.4 Gy) and
concomitant intravenous infusion of hydroxyurea (0.313 mg/m2 per min)
for 43 days. Grade 3 mucositis and myelosuppression were the main
toxicities. There was marked symptomatic improvement, and the patient
achieved a complete response. She is disease-free 24 months after
treatment, and all the acute symptoms have resolved. The regimen was
well tolerated with acceptable toxicity and led to a complete objective
response. This regimen needs further evaluation to confirm its efficacy
and to ascertain its long-term effects in children.

OBJECTIVE: To report the profile of histologic cervical nodes
involvement associated with mobile tongue squamous cell carcinoma.
PATIENTS AND METHODS: Our retrospective study concerned patients treated
from 1978 to 1998 by cervical neck dissection for mobile tongue
carcinoma. RESULTS: A population of 135 patients (90 M/45 F, sex-ratio
2) with a 53.5 mean age (19 to 75) is analyzed. Clinical palpable nodes
were present in 68 cases (50%) mainly submental-submaxillar (54).
Histologic examination showed a node involvement in 54 cases without (32
cases) or with capsular rupture (22 cases) mainly in the
jugulo-carotidian chain (46/54). Among the 67 clinically N0 patients
collected after 1990, 22 patients (33%) exhibited an histological
involvement vs 32/68 (47%) for the group presenting palpable cervical
nodes for the whole period. Histologic node involvement seemed to be
linked to the clinical status, node size and TNM stage. CONCLUSION:
Cervical lymph node treatment needs to be systematic in mobile tongue
carcinoma. The probability of histologic involvement is linked to the
loco-regional extent of disease and influences the prognosis. In N0
patients, neck dissection is required because of the frequency of
histological involvement, particularly when loss to follow-up may be
expected.

Multiple molecular alterations of FHIT in betel-associated oral
carcinoma.
SO - J Pathol 2002 Mar;196(3):300-6
AD - Institute of Oral Biology, School of Dentistry, National Yang-Ming
University, Taipei, Taiwan, ROC 112.
To determine the alterations of the FHIT (fragile histidine triad) gene
in oral squamous cell carcinoma (OSCC), this study examined mutation,
promoter methylation, mRNA transcription, and protein expression of FHIT
in OSCC associated mostly with the use of betel and/or tobacco. Analyses
of the coding exons (exons 5-9) identified a deletion of one base in
intron 4 in one tumour and a deletion of exon 7 in two tumours. Using
bisulphite genomic sequencing, 28% of the informative subjects exhibited
promoter methylation. An aberrant FHIT transcript spanning from exon 3
to exon 10, which was verified by RT-PCR analysis, was identified in 36%
of the OSCC subjects, 50% of the oral pre-invasive lesions, and 5% of
the non-cancerous match tissue. An abnormal immunohistochemical level of
Fhit was detected in 41% of OSCC subjects. A statistically significant
association was found between aberrant transcription of the FHIT gene
and an abnormal level of Fhit immunoreactivity. The results indicated
that alteration of FHIT is a frequent occurrence in OSCC and thus
suggests that the aberrance in FHIT transcription could be an early
event of oral carcinogenesis. Copyright 2002 John Wiley & Sons, Ltd.

A case of NK/T-cell lymphoma complicated by a squamous cell carcinoma of
hard palate during combination chemotherapy and radiation therapy.
SO - Korean J Intern Med 2002 Mar;17(1):69-72
AD - Department of Internal Medicine, Hanyang University College of Medicine,
Seoul, Korea.
NK/T-cell lymphoma, which often shows an angiocentric growth pattern, is
a distinct clinicopathologic entity highly associated with Epstein-Barr
virus. The disease is characterized by a destruction of the upper
respiratory tract, particularly the nasal cavity, palate and paranasal
sinuses. Interestingly, NK/T-cell lymphoma is closely linked to a
variety of complications, such as hemophagocytic syndrome, second
primary cancer, sepsis and bleeding. Here we report a case of a
50-year-old man diagnosed initially as NK/T-cell lymphoma of the
oropharynx and who developed a second primary carcinoma of the hard
palate during combination chemotherapy and radiation therapy.

SO - Rev Assoc Med Bras 2001 Jul-Sep;47(3):208-14
AD - Servico de Cirurgia de Cabeca e Pescoco, Hospital Heliopolis, Sao Paulo,
SP.
BACKGROUND: Squamous cell carcinoma (SCC) of the oral cavity occurs
mainly in the male population. The objective of the study is to identify
the main clinical and epidemiological differences of the oral SCC
between men and women. METHODS: Retrospective analysis of the charts of
228 cases of SCC of the oral cavity in women treated at the Head & Neck
Surgery Service, Heliopolis Hospital, Sao Paulo, Brazil from 1977 to
1996. The clinical and epidemiological characteristics of these cases
were compared with those of 849 male patients. RESULTS: The mean age of
women was 60.7 years (ranging 2 to 100 years) and in the male group was
55.6 years (p<0.00001). In cases where the alcohol intake and tobacco
use were absent, the tumors ocurred in older patients. The isolated
tobacco use didn't affect the distribuction by age but for the alcohol
intake (alone or combined with tobacco) the patients were younger. On
the alcohol intake, 71% of the women and 8% of the man used no alcohol.
The most common sites of tumors were tongue and floor of the mouth but
in the women group the incidence of tumors in these sites were 43%
compared with 61% in the men. CONCLUSIONS: The highest incidence of SCC
the of oral cavity occurs later in women, than in men. This could be
explained by a lesser exposure to alcohol and tobacco in women. Other
factors seem to be involved in this issue.

Increase in immune cell infiltration with progression of oral epithelium
from hyperkeratosis to dysplasia and carcinoma.

In the present study, epithelium derived lesions of various pathological
manifestations were examined histologically and immunohistochemically
for mononuclear cell infiltration. The infiltrate under the transformed
epithelium of oral lesions, was examined for differences in the
composition of immune mononuclear cells as the epithelium moves from
hyperkeratosis through various degrees of dysplasia to squamous cell
carcinoma. The study was performed on 53 human tongue tissues diagnosed
as hyperkeratosis (11 cases), mild dysplasia (nine cases), moderate and
severe dysplasia (14 cases) and squamous cell carcinoma (19 cases). A
similar analysis was performed on 30 parotid gland tissues diagnosed as
pleomorphic adenoma (14 cases) and carcinoma ex-pleomorphic adenoma (16
cases). Immunohistochemical analysis of various surface markers of the
tumour infiltrating immune cells was performed and correlated with the
transformation level as defined by morphology and the expression of p53
in the epithelium. The results revealed that, in the tongue lesions, the
changes in the epithelium from normal appearance to transformed were
accompanied by a corresponding increase in the infiltration of CD4, CD8,
CD14, CD19+20, and HLA/DR positive cells. The most significant change
was an increase in B lymphocytes in tongue lesions, that was in
accordance with the transformation level (P<0.001). In the salivary
gland, a significant number of cases did not show an infiltrate. In
cases where an infiltrate was present, a similar pattern was observed
and the more malignant tissues exhibited a higher degree of immune cell
infiltration. Copyright 2002 Cancer Research UK

Granular cell tumor (GCT) is an infrequent benign neoplasm, which
Abrikosoff accurately described in 1926. GCT probably has a neural crest
cell origin. We present the clinical and imaging findings in a

A 68-year old diabetic man with gingival cancer of the lower jaw
underwent resection of the mandible and functional neck dissection.
Swabs of a postoperative wound infection revealed methicillin-resistant
Staphylococcus aureus (MRSA). The wound was irrigated, and antibiotics
administered. The pathogens isolated were sensitive to the antibiotics
used, but the infection failed to respond to treatment. Bleeding ensued
on the 14th postoperative day (#14POD), when the wound was opened to
reveal thrombosis and rupture of the right internal jugular vein. The
patient's condition improved after ligation and surgical debridement of
the right internal jugular vein. Our experience underlines the
importance of early radiological investigation for possible thrombus
formation in the internal jugular vein in cases of postoperative wound
infection follows functional neck dissection with conservation of the
internal jugular vein. It is also important to actively treat this
condition surgically, including ligation of internal jugular vein for

Predictors and prognostic value of oral hairy leukoplakia and oral
candidiasis in South African HIV-infected patients.
SO - SADJ 2001 Dec;56(12):592-6
AD - Infectious Diseases Unit, Department of Medicine, University of Cape
Town.
BACKGROUND: Oral hairy leukoplakia and oral candidiasis diseases
(OHL/OC) are common clinical manifestations of HIV/AIDS. Sparse
literature exists from resource-limited countries on their incidence and
impact on HIV-infected patients. OBJECTIVE: To determine the predictors
and prognosis of OHL/OC in HIV-infected patients. METHODS: Patients were
drawn from a cohort established in 1992 and prospectively followed until
1997 in the adult HIV clinics, University of Cape Town. Cox hazards
regression models were fitted to determine the predictors of OHL/OC, and
the association between OHL/OC and progression to AIDS and death.
RESULTS: 218 patients presenting with OHL/OC at their initial clinic
visit were excluded. 205/772 patients developed OHL/OC (27.8 cases/100
years). White ethnicity (hazard ratio [HR] = 1.73, 95% CI 1.23-2.33),
CD4+ count < 200 cells/(L (HR = 2.55, 95% CI 1.89-3.45), total
lymphocyte count < 1250 cells/(L (HR = 1.72, 95% CI 1.28-2.31) and WHO
stage 3 or 4 (HR = 2.61, 95% CI = 1.93-3.53) where variables predictive
of increased hazard to developing OHL/OC. OHL/OC were independently
associated with hazard of AIDS (HR = 3.65, 95% CI 1.89-6.69) and death
(HR = 2.12, 95% CI 1.47-4.34). CONCLUSIONS: The presence of OHL/OC in
HIV-infected patients provides important prognostic information, and can
be used as a cost-effective tool for screening patients in therapeutic
interventions in resource-limited settings.

Many precancerous or cancerous oral lesions may resemble benign lesions
and a definitive diagnosis on clinical grounds alone may be difficult,
if not impossible, to make. The introduction of OralCDx, an oral brush
biopsy procedure, permits the dental practitioner to determine which
lesions contain atypical or dysplastic epithelial cells and require that
a conventional scalpel biopsy be performed. This article reviews the
features of the test, explains the clinical situations for which its use
is recommended, and discusses the interpretation and significance of the
biopsy reports.

Human immunodeficiency virus (HIV) infection facilitates the development
of other infections and lesions including oral papilloma, which has been
associated with human papillomavirus (HPV). In analyzing the presence of
HPV 16 and 18 by in situ hybridization in oral papillomas from five HIV+
male dental patients, HPV 16 and 18 were observed in 9 of 16 (52.2%)
histopathologic specimens. All positive lesions occurred in heterosexual
males admitting to oral sexual contact with a female partner (Pearson's
correlation; p = 0.0088). These results suggest that oral sexual
behavior may be a contributing factor in the presence of HPV 16 and 18
in oral papilloma.

Myxoma of the gingiva: a case report and literature review.
SO - Chang Gung Med J 2001 Dec;24(12):826-31
AD - Department of Periodontics, Chang Gung Memorial Hospital, Taoyuan,
Taiwan, ROC.
Soft tissue myxomas of the oral and para-oral tissue are extremely rare.
Only two cases of myxoma of gingiva have been reported in the
literature. The histogenesis of these lesions remains obscure. We report
a case of gingival myxoma in a 37-year-old man. A firm ovoid soft tissue
mass measuring 1.5 x 1.2 x 1 cm in size was noted at the mesio-lingual
gingiva of a partially impacted right mandibular third molar.
Radiographic examination revealed an impacted mandibular third molar
with normal radiographic bony consistency of the mandible. Excisional
biopsy was performed with no evidence of recurrence after 8 months.
Histological examination showed stromal mass composed of myxoid-like
fluid in fibrovascular stroma and scanty inflammatory cell infiltration,
suggesting myxomas of the oral soft tissues and jaws.
Immunohistochemical stains with S-100 protein, desmin and smooth muscle
specific actin yielded negative results, and those with alcian blue,
periodic-acid-Schiff, mucicarmine, vimentin and reticulin were positive.
Tumor cells of mesenchymal origin without neurogenic or muscular
derivations and myxoid matrix composed of acid mucopolysaccharides in
this lesion further confirmed the diagnosis of myxoma. Periodontal
ligament origin cannot be completely excluded due to tumor location and
its association with an impacted molar. However, further study is
necessary to clarify the origin and histogenesis of these lesions.

PURPOSE: To report a case of choroidal metastasis of a gingival squamous
cell carcinoma. DESIGN: Interventional case report. METHODS: Review of
the clinical history and pathologic findings. RESULTS: A 59-year-old
woman with a history of right gingival squamous cell carcinoma presented
with sudden dimness of vision in the left eye of 4 weeks duration.
Fundus examination of the left eye revealed a yellowish elevated
subretinal lesion involving the optic disk and macula. Fine-needle
aspiration biopsy of the choroidal lesion, left eye, revealed metastatic
squamous carcinoma cells. The patient was referred to a radiation
oncologist for further management. CONCLUSION: Choroidal metastasis from
gingival squamous cell carcinoma is rare, and it may develop from
hematogeneous spread.

Activation of Stat-3 as one of the early events in tobacco
chewing-mediated oral carcinogenesis.
SO - Cancer 2002 May 1;94(9):2393-400
AD - Molecular Oncology and Medical Biotechnology Division, Institute of Life
Sciences, Chandrasekharpur, Bhubaneswar, India.
BACKGROUND: The Jak/Stat signaling pathway transmits signals from many
cytokines and growth factor receptors to target genes in the nucleus.
Constitutive activation of Stat-3 recently has been observed in many
tumor cells, and dysregulation of the Stat signaling pathway has been
proposed to be implicated in malignant transformation. In the current
study for the first time to the authors's knowledge, the expression of
STAT-3 was analyzed in various stages and sites of squamous cell
carcinoma of the head and neck (HNSCC). METHODS: Tissue samples from 90
patients of tobacco chewing-mediated HNSCC representing various stages,
sites, and differentiation states were selected for studying STAT-3
protein and RNA expression. In vivo localization of STAT-3 was studied
by immunohistochemistry of paraffin embedded sections. The presence of
STAT-3 and its phophorylated and activated form pSTAT-3 was checked by
Western blotting. mRNA expression was analyzed by reverse
transcriptase-polymerase chain reaction (RT-PCR). Apoptosis analysis was
conducted by in situ ENA nick end labeling assay and hematoxylin and
eosin staining. RESULTS: Overall, 58.9% of HNSCC tumors showed very high
Stat-3 protein accumulation, and 23.3% showed intermediate accumulation
whereas 17.8% of HNSCC tumors were negative for Stat-3. No Stat-3 was
detected in normal samples, and only one of eight premalignant lesions
showed intermediate Stat-3 accumulation. On immunoblotting, very high
protein accumulation was detected in T1 and T2 classification, moderate
in T3 and T4 (P = 0.033, chi-square test), whereas no Stat-3 was
detected in normal samples. Similar trend also was found in Stat-3 mRNA
expression by RT-PCR analysis which was high in T1 and T2 (early
stages), moderate in T3 and T4 (late stages), and no expression in
normal samples. The mean apoptotic indices were 1.75, 1.88, and 1.66 for
normal, premalignant lesions, and HNSCC cases, respectively.
CONCLUSIONS: Stat-3 activation is an early event in head and neck
carcinogenesis though its role in blocking the apoptosis in vivo in
solid tumors was not observed. Copyright 2002 American Cancer

Chemoprevention of oral cancer by green tea.
SO - Gen Dent 2002 Mar-Apr;50(2):140-6
AD - Department of Oral Biology and Maxillofacial Pathology, School of
Dentistry, Medical College of Georgia, Augusta, USA.
Green tea has been a popular beverage for many centuries. Only recently,
however, has the anti-cancer power of green tea constituents been
unveiled. Green tea polyphenols are found to induce apoptosis
(programmed cell death) in many types of tumor cells, including oral
cancer cells. However, mechanisms that enable normal cells to evade the
apoptotic effect still are not understood. In this study, cell growth
and invasion assays combined with apoptosis assays were used to examine
the effects of green tea extracts, green tea polyphenols, and the most
potent green tea polyphenol, (-)-epigallocatechin-3-gallate (EGCG), on
normal human keratinocytes and oral carcinoma cells. The results showed
that green tea and its constituents selectively induce apoptosis only in
oral carcinoma cells, while EGCG was able to inhibit the growth and
invasion of oral carcinoma cells. These differential responses to green
tea and its constituents between normal and malignant cells were
correlated with the induction of p57, a cell cycle regulator. These data
suggest that the chemopreventive effects of green tea polyphenols may
involve a p57 mediated survival pathway in normal epithelial cells,
while oral carcinoma cells undergo an apoptotic pathway. Therefore,
regular consumption of green tea could be beneficial in the prevention
of oral cancer.

Spitz nevus of the tongue with pseudoepitheliomatous hyperplasia: report
of three cases of a pseudomalignant condition.
SO - Am J Surg Pathol 2002 Jun;26(6):774-7
AD - Department of Pathology, University of Bologna Medical School, Italy.
Three cases of Spitz nevus of the tongue associated with
pseudoepitheliomatous hyperplasia are reported: two occurring in
children and one in an adult. The location at an unusual site and the
complex pattern resulting from the intimate admixture of the neoplastic
melanocytic component and the hyperplastic keratinocytic component led
in each case to consider diagnoses such as malignant melanoma and
invasive squamous cell carcinoma. Staining for S-100 protein and keratin
was useful to identify and separate the two components. Spitz nevus of
the tongue carries some intriguing similarities with granular cell
tumor, suggesting a possible histogenetic and pathogenetic relationship.

CYP2A6 gene deletion reduces oral cancer risk in betel quid chewers in
Sri Lanka.
SO - Carcinogenesis 2002 Apr;23(4):595-8
AD - Laboratory of Drug Metabolism, Graduate School of Pharmaceutical
Sciences, Department of Oral Patho-biological Science, Graduate School
of Dental Medicine, Hokkaido University, Sapporo 060-0812, Japan.
We investigated the relationship between inter-individual difference in
CYP2A6 genotype and susceptibility to oral cancer among habitual betel
quid chewers in a Sri Lanka population. A total of 286 subjects showing
oral malignant or premalignant lesions and 135 control subjects with no
lesions were analyzed. The frequency of homozygotes for CYP2A6*4C
mutation, a gene deletion type of polymorphism, was significantly lower
in the case subjects than the controls. The odds ratio (OR) of the group
homozygous for the deletion was significantly lower and calculated to be
0.14 (95% CI; 0.03-0.72). In the allelic base analysis, there was also a
significant decrease in the OR of the deletion allele. Our data suggest
that deficient CYP2A6 activity due to genetic polymorphism reduces oral
cancer risk in betel quid chewers.

The inherited palmoplantar keratodermas (PPK) may be associated with a
wide variety of other ectodermal abnormalities. The coexistence of PPK
and leucoplakia may indicate the increased risk of oesophageal carcinoma
in adult life. Cutaneous horn may develop over benign, precancerous, as
well as malignant lesions, and frequently may be associated with actinic
keratoses and Bowen's disease. On the other hand, the relationship of
cutaneous horn and leucoplakia has been the subject of only a single
case report. We present a case of PPK and diffuse oral leucokeratosis
associated with relapsing cutaneous horn of the lips.

Hyoid bone position change after neck dissection for oral cancer: a
preliminary report.

AD - Department of Dentistry and Oral Surgery, Shinshu University School of
Medicine, Asahi, Matsumoto, Japan.hkurita@hsp.md.shinshu-u.ac.jp
PURPOSE: The study goal was to evaluate the change in hyoid bone
position after neck dissection and tumor resection for oral cancer.
PATIENTS AND METHODS: Twenty-seven patients who underwent surgery were
retrospectively evaluated. The hyoid bone position was measured before
and after the surgery using a topogram of computed tomography scans.
RESULTS: There was a statistically significant difference in the hyoid
bone position between preoperative and postoperative images in
anteroposterior direction (Wilcoxon signed rank test, P <.05), but there
was no significant difference in the superoinferior direction. The hyoid
bone moved anteriorly when the submandibular region was resected. In
cases in which the submental region was resected, it was variably
displaced depending on the type of suspension or reconstruction of the
resected suprahyoid muscles. CONCLUSION: This limited study suggests
that the hyoid bone is displaced after surgery for oral cancer. The
hyoid bone was displaced anteriorly if the submandibular region was
resected, and it was displaced severely if the submental region was
resected. Copyright 2002 American Association of Oral and Maxillofacial
