Prognostic significance of prolactin receptor on overall survival of patients with early breast cancer: a long-term retrospective analysis

Abstract The value of prolactin receptor (PRLR) determination in predicting overall survival has been retrospectively evaluated in a group of 170 women bearing primary breast cancer stage I, II and IIIA. All patients underwent surgery (radical or modified mastectomy or quadrantectomy and axillary dissection followed by radiotherapy according to TNM stage) between January 1977 and December 1986. In all patients, oestrogen and progesterone receptors concentrations were also determined. Overall actuarial survival was higher in patients having PRLR positive tumours when compared to patients having PRLR negative tumours (p = 0.0126). No difference in survival was observed between oestrogen or progesterone receptor positive or negative patients. Using Cox's multivariate analysis on 164 patients, stage and PRLR status were the only significant prognostic factors affecting survival (

Third-line chemotherapy with mitomycin C and lonidamine in advanced bladder cancer. Partial response in a patient with skin and lung metastases.

Skin metastases from transitional cell carcinoma are quite rare. The present case report describes the results of a combination of mitomycin C and lonidamine administered as third-line chemotherapy in a patient with pulmonary and skin involvement from bladder cancer. The partial response obtained suggests that further testing should be carried out on the activity of this association in a second-line approach

Prevention of nausea and vomiting in cisplatin-treated patients by a selective 5-hydroxytryptamine (5-HT3) receptor antagonist, ICS 205-930.

The results of an open study designed to evaluate the prevention of cisplatin-induced emesis by the specific 5-HT3 receptor antagonist ICS 205-930 are reported. Fifty-four cancer patients, treated with diverse chemotherapy regimens, all including cisplatin (greater than = 50 mg/m2), received ICS 205-930 for a total of 165 courses. ICS 205-930 (10 mg) was given i.v. immediately before the cisplatin infusion and a second 10-mg dose was given immediately after. In 109 courses (66%) the patients did not have any vomiting episodes. Nausea was absent in 44.8% of courses. More than 3 vomiting episodes occurred only in 17 (10.4%) courses, and severe nausea only in 11 (6.6%). ICS 205-930 was extremely well tolerated. Mild headache occurred during 7 courses (4.2%) in 4 patients, hypotension during 5 courses (3%) in 3 patients and lipothymia in 2 courses (1.2%) in 2 patients. These results suggest that ICS 205-930 is an effective and well tolerated antiemetic drug in patients receiving cisplatin chemotherapy

Combination chemotherapy with carboplatin and methotrexate in the treatment of advanced urothelial carcinoma. A phase II study.

The activity and toxicity of a carboplatin (300 mg/m2, day 1) and methotrexate (50 mg/m2, days 8 and 15) combination chemotherapy in the treatment of advanced urothelial cancer (UC) was evaluated in the present study. A total of 49 patients entered the study: 44 patients were evaluable for response, and 48 for toxicity. A complete response (CR) was found in 4/44 patients (9.1%) and a partial remission (PR) in 12/44 patients (27.2%) for an overall response rate of 16/44 (36.3%). Stable disease was found in 21/44 patients (47.7%), and progressive disease in 7/44 patients (15.9%). Survival was significantly longer in responding patients than nonresponders (median: 62 weeks vs 50 weeks, P < .05). Hematologic and renal toxicities were mild, thrombocytopenia and leukopenia being the most relevant side effects. The first consecutive 7 patients received methotrexate also on day 22; 5 of them underwent grade III-IV hematologic toxicity, so methotrexate on day 22 was omitted in the subsequent patients. No toxic deaths were reported. CBDCA and MTX combination chemotherapy is well tolerated and moderately active in the treatment of advanced urothelial cancer and may represent a valid alternative to cisplatin-containing regimens in patients with poor performance status and/or impaired renal function

Melatonin and human cancer.

A number of studies performed in vitro and on experimental animals supported the view that pineal gland inhibits neoplastic growth. Data in humans are scanty and controversial. In the present study we measured serum melatonin (MT), prolactin (PRL) and growth hormone (GH) concentrations, at 08.00 and 24.00, in 132 cancer patients and in 58 healthy control subjects. The patients were stratified according to histology and stage of disease as follows: 30 stage I-II and 45 stage III-IV breast cancer (BC); 39 stage III-IV lung cancer; 18 advanced gastrointestinal (GI) cancer. We also measured MT levels, at the same time-points, in 20 women with primary BC before and after radical mastectomy. Finally, we evaluated the circadian rhythm of serum MT in 18 patients with advanced cancer. On the whole, the patients with advanced tumors showed serum MT levels significantly higher than controls, without any correlation with PRL and GH values. When looking at stage III-IV vs stage I-II BC patients, significantly higher MT levels have been found in the former group. The surgical removal of the primary BC was not associated with any changes in MT values at both time points considered. A highly significant rhythm of serum MT was recorded in advanced cancer patients and the rhythmic parameters were substantially superimposable on those of the control subjects
