Results of treatment of stage I-III breast cancer in black Americans. The Cook County Hospital experience, 1973-1987.

Whether the prognosis for black women with breast cancer differs from that of nonblack women remains controversial. The treatment results of 526 black women who received definitive therapy for Stage I-III breast cancer at Cook County Hospital, 1973 through 1987 are presented. The 5-year and 10-year projected survival rates for 272 node-negative patients (83.9% and 76.6%, respectively) and for 72 node-positive nonadjuvant treated patients (58.1% and 35.2%, respectively) are similar to those reported in the literature for nonblack patients. Adjuvant therapy improved the projected relapse-free (P = 0.0744) and overall survival curves (P = 0.0448) for 182 node-positive patients compared with nonadjuvant patients. The greatest benefit was seen for patients greater than 50 years of age with one to three positive nodes. The incidence of estrogen and progesterone receptors was found to be similar to those reported for nonblack patients. Once breast cancer has been diagnosed and appropriately treated, there appear to be few differences in the natural history of breast cancer between black and nonblack patients.

Pelvic exenteration.

Sixty-eight patients at the University of Illinois, Cook County, and the West Side Veterans Administration hospitals underwent pelvic exenteration for advanced pelvic malignancies during the 15-year period from 1969 to 1984. Thirty-two had colorectal cancers, eleven cervical, seven bladder, and six vulvar; in twelve the cancers were in miscellaneous pelvic sites. Forty-five exenterations were done with intent to cure, and twenty-three for palliation of patients with bulky, necrotic tumors that had caused symptomatic fistulae, local sepsis, chronic bleeding, or severe localized pain. The total 30-day postoperative mortality was 4.4% (3/68). The 5-year survival rate of patients who underwent curative exenteration was 33% (median 27 months). Pelvic exenteration appears to be a feasible surgical procedure for a variety of advanced malignancies as well as for palliation of severely symptomatic patients.

Rate of regeneration of sensory axons in transected rat sciatic nerve repaired with epineurial sutures.

Rat sciatic nerves were cut and the ends were rejoined using epineurial sutures. The most rapidly regenerating sensory axons, as measured by the pinch test, grew at a rate of 3.2 +/- 0.2 (SE) mm/day after a delay of 4.0 +/- 0.3 (SE) days. Regenerating axons began to grow beyond the site of injury about 2 days later in sutured nerves than in crushed nerves; this difference provides an estimate of the scar delay in sutured nerves. The rate of axonal outgrowth was slower in sutured nerves than in crushed nerves throughout the distal stump.
