Racial Differences in Breast Cancer Patients<xref ref-type="fn" rid="FN2">2</xref>

One thousand seventy-eight patients diagnosed with primary breast cancer were examined for racial differences in histopathologic and clinical parameters. There were no observed differences in tumor histopathologic type or tumor endocrine status between races. There were no differences with respect to time to breast tumor recurrence observed between black and white patients. However, differences were observed in factors that contributed to tumor stage at diagnosis and to tumor grade. Survival differences observed in univariant analysis of blacks vs. whites were explainable by the presence of more severe skin involvement, tumor grade, and tumor size at diagnosis in the black patients.

Gastric leiomyosarcoma.

A retrospective study was made of 28 patients who had gastric leiomyosarcomas to identify histologic patterns and radiologic appearances. Three histologic patterns were identified: spindle cell, epithelioid, and pleomorphic. The histopathologic type of tumor did not correlate with the size, the grade of malignancy, or the location of the mass within the stomach. All but one tumor presented as a submucosal mass by barium contrast examination. Ulceration was present in 17 of 28 patients. Sonographic examination in six patients and computed tomography (CT) in one provided further information about the degree of extragastric extension. Sonographically the masses were echogenic in three patients, hypoechoic in two, and anechoic in one. Surgery remains the only curative therapy and surgical excision is recommended regardless of mass size.

A study on the etiological factors of bilharzial bladder cancer in Egypt: 4. beta-carotene and vitamin A level in serum.

The possible role of vitamin A in the pathogenesis of bilharzial bladder cancer among Egyptians, particularly as it relates to the histopathologic tumor type, was investigated. Bilharzial patients and bladder cancer patients with squamous cell carcinoma, the most prevalent type in Egypt, showed significantly lower levels of vitamin A than normal male subjects. In contrast bladder cancer patients with transitional cell carcinoma had levels that were not significantly different from normal male subjects. The possible role of vitamin A in the etiology of bilharzial bladder cancer is discussed.

Parotid gland tumors

Summary One hundred cases of parotid tumors are presented and studied from a clinicopathologic viewpoint. The clinical features of the tumor had no definite bearing on the final histopathologic type of tumor and, therefore, were not reliable guides for the preoperative diagnosis and treatment of parotid tumors. The definite reduction in recurrence rate by subtotal parotidectomy for benign tumors should lead to the wider use of the procedure despite the higher rate of facial nerve dysfunction which in the great majority of cases is temporary.
