Advanced male non-seminomatous germ-cell tumours. Combination chemotherapy with cis-platinum, vinblastine and bleomycin.

Nineteen men with advanced germ-cell tumours were treated with a combination of vinblastine, bleomycin and cis-diamminedichloroplatinum II (cis-platinum). One patient died nine days after starting chemotherapy. Seventeen patients responded to therapy (14 completely and three partially). Toxicity was very high, and three patients died of septicaemia during therapy. Eight patients remain in complete remission 36 to 80 weeks after starting chemotherapy.

Thymidine sensitivity of cultured leukaemic lymphocytes.

Cultured leukaemic lymphocytes from patients with T, null, or pre-B acute lymphoblastic leukaemia are shown to be highly sensitive to growth inhibition by thymidine. Thymidine sensitivity was correlated with reduced activity of the catabolic enzyme thymidine phosphorylase and sustained elevation of the deoxythymidine triphosphate pool after exposure to thymidine. It is suggested that thymidine may have a role in the management of certain acute lymphoblastic leukaemias of lymphomas.

Undifferentiated carcinoma in young men: the atypical teratoma syndrome.

In 5 young men with apparent undifferentiated carcinoma involving lung, mediastinum, and lymph-nodes subsequent response to treatment, tumour-marker analysis, and histology review suggested a diagnosis of embryonal-cell carcinoma. It is suggested that atypical presentation of extragonadal germ-cell tumours may be common. Because such tumours respond to chemotherapy, accurate diagnosis is essential.

Cis-dichlorodiammine platinum (II) in advanced ovarian carcinoma.

Twenty-seven patients with advanced ovarian cancer were treated with a total of 80 courses of cis-dichlorodiammine platinum (II) (cisplatin). The doses in three courses were less than 50 mg/m2, in 64 courses they were 50 mg/m2, and in eight courses they were 100 mg/m2. In addition, five courses of low-dose daily treatment (20 mg/m2 for five days) were administered. Twelve patients received cisplatin alone, 12 received cisplatin and cyclophosphamide (750 mg/m2), and three patients received cisplatin with other drugs. There were eight responders (33%) in the 24 evaluable patients. Renal toxicity occurred in four patients, ototoxicity in four, and leucopenia (which was life-threatening in one patient) occurred in 16 patients (white cell count less than 3.0 X 10(9)/L). There were two early drug-related deaths. The median survival of patients who responded to cisplatin treatment was longer than 30 weeks compared with nine weeks for non-responders.

Unknown primary adenocarcinoma: incidence of overinvestigation and natural history.

Out of 1300 patients referred to a medical oncology unit, there were 87 with metastatic cancer in whom a primary tumour site was not evident from the history and after physical examination and chest radiography had been carried out. An analysis of the investigations performed in these patients and their results showed that in only eight of the 87 patients did non-surgical investigations at presentation determine the primary site. In two patients it was identified by diagnostic laparotomy, and in a further 13 clinical follow-up led to recognition of the primary tumour site before death. Few investigations should be performed in patients in whom the primary site is known since they have a low yield, and in our population identifying the primary tumour did not improve the outcome or alter management. Treatable tumours should be excluded, and this may be done in most cases by simple blood tests, particularly those measuring acid phosphatase activity and other tumour markers.

Burkitt's lymphoma in Australia.

Three patients with Burkitt's lymphoma have been seen at Royal Prince Alfred Hospital during the past 18 months. Following treatment, two patients are in complete clinical remission.

Possible tumor localization of Tc-99m-labeled liposomes: effects of lipid composition, charge, and liposome size.

The possible in vivo distribution of liposomes after they have been directly labeled with Tc-99m has been studied in rats bearing the Walker 256 carcinoma. The importance of lipid composition, charge, and size of liposome were studied with respect to possible tumor-localizing properties. Tumor uptake was best with small, fluid-membrane, negatively charged liposomes, as indicated by the distribution of the Tc-99m label. The uptake was visualized on scintigrams.
