Women and Squamous Cell Carcinomas of the Oral Cavity and Oropharynx: Is There Something New?
ABSTRACT Incidence of squamous cell carcinoma (SCC) of the oral cavity and oropharynx is increasing in French female patients. The objective of this study was to study the clinical and demographic characteristics and the prognosis of this female population. Secondary outcomes were to determine if a subgroup of patient had a different prognosis.
A prospective study from 1989 to 2002 of all female patients presenting SCC of the upper aerodogestive tract was conducted. Data for 171 women were extracted. Clinical and histological features were analyzed using chi(2) and log-rank tests along with the Kaplan Meier method and multivariate analysis using the Cox regression procedure.
Mean patient age was 62 years. Of the study population, 48.5% used tobacco and 34.5% used alcohol. The relative risk of death for overall and cancer-specific survival increased for patients below the age of 45 or over the age of 70 (95% Cl; 0.3-1.05; P = .0085). Tobacco consumption decreased cancer-specific and overall survival (P = .0008 and .0001, respectively). The other prognostic factors we found were tumor and nodal status, previous or simultaneous cancer, oral cavity primary site.
Prognosis of oropharyngeal and oral squamous cell carcinomas is less favorable in females who smoke as well as in younger and older women. With these patients, the oversight must be closer. Smoking, however, should be stopped.

ABSTRACT: Despite early diagnosis and treatment, almost 20 % of patients with early-stage (cT1-cT2N0) oral tongue squamous cell carcinoma (OTSCC) still die of their disease. The prognosis of OTSCC patients is influenced by several demographic, clinical, and histopathologic factors. The aim of this multicenter international study was to find which of the factors age, gender, stage, grade, lymphocytic host response, perineural invasion, worst pattern of invasion, or depth of invasion has the strongest prognostic power in early-stage OTSCC. Patient data of 479 patients with early-stage (cT1-2N0) OTSCC in Finland, Brazil, and the USA were retrieved and analyzed using Cox proportional hazards regression models. Our results indicate that depth of invasion (DOI) and worst pattern of invasion (WPOI) are the strongest pathological predictors for locoregional recurrence, with a hazard ratio (HR) for 4 mm DOI of 1.67 (95 % confidence interval (CI) 1.07-2.60) and HR for WPOI of 1.46 (95 % CI 0.95-2.25). In addition, mortality from early OTSCC was also predicted by DOI (HR 2.44, 95 % CI 1.34-4.47) and by WPOI (HR 2.34, 95 % CI 1.26-4.32). We suggest that clinically early-stage oral tongue carcinomas 4 mm or deeper, or with a growth pattern of small cell islands or satellites, should be considered as high-risk tumors which require multimodality treatment.Archiv für Pathologische Anatomie und Physiologie und für Klinische Medicin 04/2015; DOI:10.1007/s00428-015-1758-z · 2.56 Impact Factor

ABSTRACT: Tobacco and alcohol are the main extrinsic etiological factors for the genesis of oral squamous cell carcinoma (SCC), but it is still not clear if the presence of these factors interfere with clinical, pathologic and molecular characteristics or with the prognosis of the disease. In the present study, these characteristics were reviewed, establishing comparisons between the lesions of patients exposed and not exposed to tobacco and alcohol. We observed that oral SCC in non smokers and non alcohol drinkers occur mainly in female patients, under 50 or over 70 years old. The lesions tend to be less aggressive in this group of patients and have a better prognosis. The molecular characteristics of these malignant tumors also appear to be influenced by the presence of these habits, once mutations of p53 have been associated with tobacco and alcohol use. The understanding of the differences between the neoplasms of these two groups of patients can contribute to the management of this cancer, which could lead to advances in the determination of more appropriate therapeutic measures.12/2011; 27(1):69-73.
