Both chemotherapy and interleukin-2 and/or interferon-alpha produce objective responses in a proportion of advanced malignant melanoma patients. While duration of response to chemotherapy is short, i.e. usually below 4 months, immunotherapy has resulted in a small number of long-lasting remissions in patients with metastatic melanoma. In two consecutive phase II trials in a total of 67 patients, we assessed the potential synergism between both modalities, i.e. chemo- and immunotherapy. ⋯ The sequential combination of chemotherapy and rIL-2 plus rIFN-alpha had at least additive therapeutic activity against metastatic malignant melanoma. The schedules produced long-lasting remissions and were tolerated well overall. These trials substantiate a potential role for low to intermediate dose immunotherapy in maintaining and consolidating therapeutic effects of chemotherapy in metastatic melanoma.

To investigate influences of a recall due to inconclusive findings on screening mammography, 45 women were examined with psychological ('mood' and 'coping'), endocrine and immunological tests immediately after complete mammography (first interview), 2-3 days after the initial screening mammography, and 3 weeks after the women had been informed of normal findings (second interview). The mood score in the first interview was significantly lower than in the second. No differences were found in the endocrine and immunological tests. The recall for complete mammography provoked a significant short-term emotional reaction not reflected in changes in the endocrine and immune functions.

Randomized Controlled Trial Multicenter Study Clinical Trial
Oral ondansetron in the prevention of chemotherapy-induced emesis in breast cancer patients. French Ondansetron Study Group.
A multicentre randomised, double-blind parallel group study has been carried out in order to confirm the antiemetic efficacy of orally administered ondansetron. A total of 259 chemotherapy-naive breast cancer patients treated with a 5-fluorouracil, doxorubicin, cyclophosphamide (FAC) or 5-fluorouracil, epirubicin, cyclophosphamide (FEC) regimen were randomly assigned to ondansetron (OND) 8 mg tablet or alizapride (ALI) 150 mg intravenous (i.v.) injection, prior to chemotherapy. These treatments were then followed by OND 8 mg tablet or ALI 50 mg tablet, respectively, 8 to 12 h later. ⋯ In terms of quality of life in relation to emesis phenomena, OND was significantly superior to ALI (P = 0.04). Both treatments were well tolerated. In the prevention of the prolonged emesis induced by FAC/FEC-type emetogenic chemotherapy, orally administered OND was superior to ALI, given as an i.v. injection and followed by tablets.

A prospective trial was performed to better assess the risk of nausea and vomiting and the rescue value of tropisetron (TRO), a 5-HT3 receptor antagonist, in 88 patients undergoing fractionated radiotherapy to the abdomen or to large supradiaphragmatic fields and failing a first anti-emetic trial with metoclopramide (MET). Nausea was graded 0 (absent), 1 (mild), 2 (moderate) and 3 (severe). Nausea requiring anti-emetics (> or = grade 2) was present in 64% of the patients. ⋯ MET helped to eliminate emesis in one third of these patients. TRO helped to control vomiting in 73% of the salvaged patients. Constipation was observed in 8 patients on TRO and was a reason to stop the medication in 4 cases.

In vitro and in vivo neuroblastoma models were used to determine whether improvements in tumour targeting in vivo and therapeutic efficacy in vitro could result from the use of no-carrier-added (n.c.a.) [131I]MIBG. Results were compared with use of the conventional therapy MIBG preparation (ex. [131I]MIBG) of lower specific activity which is produced by iodide exchange reaction. The efficacy of n.c.a. [131I]MIBG was compared with that of [131I]MIBG over a range of specific activities by the assessment of neuroblastoma spheroid growth delay. ⋯ However, uptake and retention in the blood was unaltered. For all tissues examined, the 3-day calculations were undertaken to predict organ to tumour dose ratios which would result in human neuroblastoma patients with each of the [131I]MIBG preparations. These results suggest that significant therapeutic gain may be achieved by the use of n.c.a. [131I]MIBG as a treatment agent in neuroblastoma. neuroblastoma.
