Combined endocrine treatment of postmenopausal patients with advanced breast cancer. A randomized trial of tamoxifen vs. tamoxifen plus aminoglutethimide and hydrocortisone.

The therapeutic efficacy of combined endocrine therapy with tamoxifen, aminoglutethimide and hydrocortisone (T+AG+H) was evaluated against treatment with tamoxifen (T) alone in 210 patients above 65 years of age with metastatic breast cancer. The treatment results have been assessed for the 166 fully evaluable patients and were the following for the T and T+AG+H groups, respectively: PD: 31 and 35%; NC: 35 and 37%; PR: 13 and 16%; and CR: 21 and 12%. The overall treatment results are not statistically different (p = 0.35) and the 95% C.L. of the difference of the response rates are -8% to +20%. The median duration of remission was approximately 24 months in both treatment groups (p = 0.31). The time to treatment failure was comparable with median values of 10 and 8 months in the T and the T+AG+H groups respectively (p = 0.17). Toxicity was more frequent and severe in the combined treatment group and could in most instances be attributed to treatment with AG+H. In conclusion, the simultaneous use of T and AG and H does not seem to improve the therapeutic results in postmenopausal patients with advanced breast cancer.

Aggressive fibromatosis.

Fifteen patients with aggressive fibromatosis are presented. The patients ranged in age from one to 64 years, an average of 26 years, and the median time of follow-up study after treatment was ten years (a range of 2.5 to 22.0). Within this period, 60 per cent (nine of 15) of the tumors recurred. In a survey of the literature, when simple excision was compared with wide extirpation, the latter was found significantly superior (p less than 0.01) in terms of limiting a recurrence of the tumor. The results of a pathoanatomic study found that the number of mast cells and the size of the primary tumor could not prognosticate the clinical course. It was concluded that aggressive fibromatosis should be evaluated and treated like a low malignant soft tissue tumor.

Intra-uterine exposure to saccharin and risk of bladder cancer in man.

Animal experiments show that rats fed saccharin are more likely to develop bladder tumours if they have been exposed to saccharin in utero through their mothers' food. The risk of bladder tumours in humans following in utero exposure to saccharin has not been evaluated previously. In Denmark the use of saccharin increased sharply during the second World War as a result of scarcity of sugar, and import and export figures indicate that saccharin consumption was on average 4-5 times higher during the war-time period than in the pre-war decade. The risk of bladder tumours at ages 20-34 was 1.0 (95% confidence interval 0.7-1.6) among men born in 1941-1945 compared with men born 1931-1940. Among women the risk was 0.3 (0.1-1.0). This study provides no evidence of an increased risk of human bladder cancer during the first 30-35 years of life associated with in utero saccharine exposure.

Pattern of metastases in human breast carcinoma in relation to estrogen receptor status.

The distribution of metastases at the first recurrence of breast cancer was studied in 57 estrogen receptor (ER) positive and in 23 ER negative patients, who constituted a subset of 460 patients with operable breast cancer. The pattern of metastases with respect to localization of metastases and the dominant site of first recurrence was similar in patients with ER positive and ER negative tumours. The recurrence-free survival (RFS) and the overall survival were associated with the ER status in the 460 patients. ER positive patients had both a significantly longer RFS (p = 0.0024) and survival (p = 0.0001) compared to ER negative patients. Survival after recurrence was prolonged in patients with soft tissue recurrences only, and the proportion of dead patients was highest in receptor negative patients with metastases to bone and viscera. In conclusion, we could not demonstrate that ER positive and negative tumours have a propensity for recurrence at specific sites.
