Sex hormone binding globulin in breast cancer.

The present study was undertaken to determine the significance of sex hormone binding globulin, the major and specific binding protein for testosterone and estradiol, in breast cancer. Among breast cancer patients, lower serum levels of Sex hormone binding globulin and higher levels of testosterone were observed. Sex hormone binding globulin showed an inverse relationship with testosterone and total cholesterol, and a direct relation with HDL-cholesterol.

Osteosarcoma with cutaneous metastases. A case report.

Background: Osteosarcomas, despite their aggressive nature and propensity to metastasize, only rarely give rise to skin deposits.

Case: We report a case of a femoral osteosarcoma in which cutaneous scalp and neck metastases developed 3 years after treatment of the primary disease. Fine needle aspiration was pivotal in diagnosing the secondary disease.

Malignant fibrous histiocytoma of the chest wall masquerading as medullary breast carcinoma: a case report.

Background: Cytologic diagnosis of malignant fibrous histiocytoma can be problematic, as these neoplasms are known to mimic multiple other conditions.

Case: A fine needle aspirate from a 60-year-old woman was diagnosed at 2 institutions as medullary carcinoma of the breast. The patient received neo-adjuvant chemoradiotherapy before the tumor war excised.

Quantitative analysis of radiation-associated cellular changes in oral cancer and their correlations with histologic grade and clinical stage: a multivariate evaluation of 43 patients.

Objective: To quantitate radiation-associated cytologic abnormalities in oral cancer cells and analyze their relationships with radiation dose, clinical stage and histologic grade.

Study Design: Forty-three oral cancer patients receiving 2 Gy of fractionated radiotherapy per day were enrolled. Scrape smears were taken from the tumor surface before treatment and serially after 6-, 12-, 18- and 24-Gy fractions.

Ki-67 expression in cytologic scrapes from oral squamous cell carcinoma before and after 24 gray radiotherapy--a study on 43 patients.

Objective: To study the Ki-67 labeling indices in surface scrape smears from patients with oral squamous cell carcinoma before and after 24 Gray radiotherapy.

Study Design: Forty three patients with histologically documented squamous cell carcinoma of the oral cavity were sampled by means of surface scrape smears prior to therapy and after receiving 24 Gray fractionated radiotherapy. These smears were stained for Ki-67 expression using the avidin biotin alkaline phosphatase technique.
