Androgen in the treatment of refractory anemia.

We retrospectively evaluated the efficacy of androgen in the treatment of refractory anemia (RA) and compared patient characteristics and the probability of survival in androgen-responder and nonresponder groups. Forty patients with RA were treated in our hospital between 1975-1989, and 27 were treated with various derivatives of androgen. Eleven of the latter responded effectively to androgen therapy, representing an efficacy rate of 40.7%, higher than that of any other treatments thus far reported. The probability of 10-year survival estimated by the Kaplan-Meier method was 75.0% for the responder group and 41.3% for nonresponders, with a median follow-up of 1202 and 1272 days, respectively. In addition, the percent probability of transformation-free survival was higher among androgen-responders than among nonresponders, though the difference was not significant. Transformation from RA to RAEB or overt leukemia was seen in only one case among the former group, but in six among the latter. With respect to patient characteristics, only the percentage of marrow myeloblasts differed significantly between the groups.

pS2 expression and response to hormonal therapy in patients with advanced breast cancer.

Seventy-two patients with advanced breast carcinoma (42% bone, 25% visceral, 5.5% soft tissue, and 27.5% multiple site metastases) were evaluated to determine the relationship between tumor expression of the estrogen-regulated protein pS2, estrogen receptor (ER) or progesterone receptor (PgR) content, and response to hormonal therapy. Twenty-nine % of tumors were pS2 positive, 64% were ER positive, and 29% were PgR positive. Of the ER-positive patients (n = 43), 15 (35%) had greater than 10% of the invasive carcinoma which immunostained for pS2 (these were considered pS2 positive). Only 3 of 24 ER-negative tumors were pS2 positive. A weak association between pS2 expression and ER content (P = 0.08) but not PgR content was observed. Of pS2-positive patients, 52% had a partial or complete response to hormonal therapy. In 24% of pS2-positive patients the disease stabilized with treatment. In contrast, 27% of pS2-negative patients had a partial or complete response. In 10% of these patients the disease stabilized. Similar associations between therapeutic response and ER or PgR were not observed. The odds of having a clinical response to hormonal therapy was greater for pS2-positive than for ER- or PgR-positive tumors. pS2 expression may define a subset of ER-positive tumors that are more likely to respond to hormonal treatment.

[Role of supporting therapy of Juzentaiho-to (JTT) in advanced breast cancer patients].

The patients were randomized with the envelope method, dividing into either A- or B-group. A-group was treated with JTT combined with chemoendocrine therapy. B-group was treated with only chemo-endocrine therapy. Between May 1985 and December 1987, 130 pts were used for this trial, 119 pts were evaluable, and 58 pts belonged to A-group and 61 to B-group. The pts characteristics were well balanced in both those groups. There was no significant difference in the response rates between A- and B-groups. The survival rate up to 38 months was not significantly different between the two groups, but in JTT-SHO group, the survival was significantly higher in the pts belonging to the A-group (Greenwood, p less than 0.05). The quality of life (QOL) was expressed as self-assessment scores for physical condition, appetite and the coldness of extremities. It improved significantly in A-group, especially, by prevention of bone marrow suppression by chemotherapy. It was concluded that treatment with JTT is better than without JTT in treatment for advanced breast cancer patients.

Varicocele: medical and surgical treatment.

Varicocele is the most frequent finding in male infertility. Thirty percent of infertile male patients requesting treatment present with varicocele. Between December 1971 and December 1984, 151 infertile patients presenting varicocele were treated in this study: 28 underwent medical treatment, 38 surgical treatment, and 23 both medical and surgical treatment. The spermograms of all the patients were studied before and after treatment. The following variables were considered: volume, sperm count, percentages of general motility and of grade III sperm, and of oval forms. There was not a significant statistical difference in the analysis of the spermogram parameters before and after treatment in the three groups. The pregnancy rate for the medical-surgical group was 60.9% and for the surgical group 47.4%--not a statistically significant difference. The purely medically treated group had a pregnancy rate of 25%, which is significantly lower than the other groups.

Do androgens enhance the response to antithymocyte globulin in patients with aplastic anemia? A prospective randomized trial.

We analyzed the effect of antithymocyte globulin (ATG) with or without androgens in 121 patients with aplastic anemia. Fifty-three patients with moderate to severe aplastic anemia were prospectively randomized to receive ATG with or without oral androgens. Eleven of 26 patients (42%) receiving ATG plus androgen responded, including three complete and eight partial responses. Twelve of 27 patients (44%) receiving ATG plus placebo responded, including five complete and seven partial responses. The difference in response rates was not significant (P greater than .9). Survival was also comparable in the two groups; for patients with severe aplastic anemia, actuarial survival at two years was 55% +/- 24% (95% confidence interval) in patients receiving ATG plus androgen compared with 50% +/- 24% in the ATG plus placebo group (P = .65). Furthermore, results in both groups were indistinguishable from those obtained in 68 historical controls receiving ATG without androgens. These data indicate that androgens are not required in order to respond to antithymocyte globulin and the addition of androgens, as used in this trial, did not significantly improve response rates to ATG treatment.
