Thrombocytosis in women with vulvar carcinoma.

Thrombocytosis (platelet count >400 x 10(9)/L) is frequently found in association with malignant disease. Although the pathogenesis of thrombocytosis in malignancy is currently unclear, it appears to be a poor prognostic factor in patients with lung, colon, breast, and cervical carcinoma. The current study was initiated to assess the incidence of thrombocytosis in vulvar carcinoma and to evaluate its prognostic significance for patients with vulvar carcinoma. The pretreatment platelet counts of 201 women treated for vulvar cancer were reviewed and correlated to the patient's age, stage of disease, node status, histologic type, and outcome. Differences between categories were analyzed by means of the ANOVA test, and survival was compared using the log-rank test on the Kaplan-Meier life table. Thrombocytosis was presented in 14.92% of patients with vulvar malignancies and in 15.46% of patients with squamous cell carcinoma of the vulva. No correlation was found between thrombocytosis and tumor size, incidence of lymph node metastases, or stage of the disease. The 5-year survival rate for patients with thrombocytosis was 89.29%, which was not significantly different from the 76.47% 5-year survival of patients with normal platelet counts (P = 0.586). When adjusted for age, histological differentiation, number of tumors, staging, incidence of nodal metastases, platelet count, hemoglobin, and white blood count, only the staging, number of tumors, and histological differentiation were associated with an unfavorable prognosis (P = 0.0001, P = 0.003, P = 0.03, respectively). Thrombocytosis was not found to be a prognostic factor in patients with carcinoma of the vulva in this series of 201 patients.

Thrombocytosis as a prognostic factor in women with cervical cancer.

BACKGROUND: Thrombocytosis (a platelet count > 400 x 10(9)/l) is found frequently in association with malignant disease and recently has been suggested to be a poor prognostic indicator in patients with cervical cancer. The authors decided to see if these findings could be verified. METHODS: The pretreatment platelet counts of 643 women treated for cervical cancer between 1983 and 1992 were reviewed and correlated to each patient's age, stage of disease, histologic type, node status (when available), and outcome. Differences between groups were analyzed using the chi 2 test, and survival was compared using the log rank test on Kaplan-Meier life tables. RESULTS: The 5-year survival rate for patients with thrombocytosis was 57.1%, which was significantly worse than the 76.5% for those with normal platelet counts (P < 0.01). When adjusted for stage of disease, however, thrombocytosis failed to have a significant effect on patient survival. There was also no relation between thrombocytosis and the incidence of positive lymph nodes. CONCLUSION: Thrombocytosis was not found to be an independent prognostic factor in patients with carcinoma of the cervix in this series of 643 patients.

Squamous cell carcinoma antigen: pretreatment levels as an indicator of advanced or metastatic disease.

Pretreatment values of squamous cell carcinoma antigen (SCC) were obtained in 100 consecutive patients with squamous cell carcinoma of the cervix presenting to the Regional Gynaecological Oncology Centre in Gateshead, UK. Nine patients deemed to have locally advanced disease not suitable for primary surgery had elevated levels. Ninety-one patients were suitable for primary surgery. Sixty-seven had normal SCC levels, two of which had lymph node metastases. Twenty-four had elevated SCC levels, 14 of which had lymph node metastases. Two early recurrences have been detected in the raised SCC group where no lymph node metastases were present. Elevated levels of SCC in the pretreatment assessment indicate a high risk of lymph node metastases and of developing recurrent disease after primary surgery.

Dietary and other risk factors in the aetiology of cholelithiasis: a case control study.

We studied the effect of dietary factors and a variety of other risk factors on the development of cholelithiasis through a case control study. The study involved 96 cases and 118 age and sex matched controls. All cases and controls were interviewed with regard to a variety of risk factors and frequency of consumption of over 100 food items. Analysis was done both by chi square and a multiple logistic regression model. From all the dietary factors the only ones that showed a positive statistically significantly (p less than 0.05) association was consumption of animal fat as expressed by eating all visible fat on the meat and using butter on the table. Interestingly high consumption of olive oil had a negative (protective) association with the disease. A negative association was also found with smoking and holding a job demanding hard labor.
