Disordered nocturnal prolactin regulation in women with breast cancer.

Mean 24-hr prolactin concentrations were determined in 25 female control subjects, 16 women with benign breast masses, and 23 subjects with breast cancer. This evaluation performed before breast surgery revealed significantly decreased (p less than 0.02) nocturnal (12 a.m. to 7 a.m.) prolactin concentrations in 12 postmenopausal breast cancer subjects that contrasted with significantly increased (p less than 0.05) nocturnal prolactin levels in five luteal-phase premenopausal women with breast cancers. Prolactin concentrations in patients with benign breast disease were not significantly different from control subjects. Two of the premenopausal breast cancer patients had marked preoperative elevations in their mean 24-hr prolactin levels, and they were two of the three subjects who have since expired. Nocturnal prolactin secretion was significantly decreased (p less than 0.03) in four premenopausal breast cancer patients when they were studied 1 year after surgery; however, it remained the same in the eight postmenopausal breast cancer patients similarly evaluated. Although disordered prolactin regulation has been found in these women with breast cancer, its role in the etiology and progression of human cancer is still uncertain.

Twenty-four-hour preoperative endocrine profiles in women with benign and malignant breast disease.

Mean 24-hr growth hormone, luteinizing hormone, follicle-stimulating hormone, estradiol, and progesterone concentrations determined preoperatively in 16 women with benign breast masses and 17 patients with breast cancer were similar to those levels found in 25 age- and weight-matched control subjects. Mean 24-hr testosterone levels, however, were significantly elevated in women with breast cancer evaluated in the luteal phase of their cycles and were normal in postmenopausal breast cancer women. In addition, serum thyroid-stimulating hormone, thyroxine, cholesterol, and triglyceride levels were normal in these subjects. Plasma cortisols and urinary 17-hydroxysteroid excretion tended to be higher in both the benign and malignant breast disease group and probably reflected preoperative anxiety. Hence, we have found normal concentrations of a variety of endocrine and other biochemical agents that can stimulate breast tissue growth and/or have been previously reported to be disordered in women with breast cancer.

Treatment of carotid body tumors.

Twenty patients presenting with 23 carotid body tumors compose this study group. Eleven patients underwent resection of 14 tumors, while nine patients either refused resection or were unresectable. There was one tumor recurrence following resection. Of the patients not having resection, none have experienced morbidity or death. While surgical excision remains the mainstay of treatment for carotid body tumors, those patients not undergoing resection can survive for long periods.
