During induction chemotherapy, we experienced the false elevation of the tumor marker alpha-fetoprotein (AFP) in some disseminated testicular cancer patients. We discussed the possibility of the false elevation of the tumor marker AFP and evaluated the relationship between AFP and the markers of liver damage (GOT, GPT, LDH, etc.), the elevation of which were caused by induction chemotherapy of the VAB-6 regimen. We evaluated each variable of the eleven patients with disseminated testicular cancer who had been treated in our hospital between 1979 and 1984. The elevation of each marker of liver damage was induced by the VAB-6 regimen, immediately after the end of each induction chemotherapy but not by other induction chemotherapy regimens. A statistical study confirmed that there was a close correlation between the elevation of AFP and of the markers of liver damage, that is induced frequently by the induction chemotherapy of VAB-6 regimen.

Four brothers who developed testicular neoplasms, one bilaterally, are described. Histologic examination showed four of the tumors to be seminomas and one to be a mixed germ cell tumor. Three of the brothers are alive. Apart from a late-onset bladder carcinoma in their father and a pulmonary cancer in a maternal uncle, cancers were not recorded in the extended kindred. One patient, a sister, and the parents had normal frequency of sister chromatid exchange (SCE) and chromosome aberrations, whereas the two patients sampled after radiation showed increase in one or both. The father was found heterozygous in 12 and the mother in 8 genetic marker systems among 25 tested. For the blood group gene loci JK and MNSs, and the erythrocyte enzyme locus GPT the father had given the same allele to all three affected sons examined. The mother had given different alleles to the sons in all of her informative markers. On the model of a recessively acting susceptibility gene, only JK and GPT remained consistent with linkage without recombination. These investigations did not add support to a genetic etiology for the unusual family occurrence of testicular cancer. An apparent birth-order effect on time at onset/diagnosis in this and published families suggests time-limited environmental factors. Nevertheless, JK, MNSs, and GPT should be included in future testis cancer families to test the model of a "dominant" genetic predisposition.

A phase II study on recombinant human leukocyte A interferon (rIFN-alpha A) was carried out in 30 patients with urogenital cancers. Each patient received rIFN-alpha A by i.m. injection every day for at least 4 weeks. The initial daily dose was 3 X 10(6) U, being escalated at intervals of 3 days or more up to 50 X 10(6) U. The results are summarized as follows: In aged patients, the daily dose appropriate for everyday i.m. injection was considered to be 9 X 10(6) U or below, judging from the adverse reactions observed. According to Koyama and Saito's response criteria, partial response (PR) and minor response (MR) were obtained, respectively, in 3 and 1 out of 12 patients with renal cell carcinoma, while PR was seen in 1 out of 9 with urothelial cancer. No response was observed in patients with testicular cancer and in those with prostatic cancer. Various kinds of adverse reactions were recognized and each patient showed one reaction or more. Fever, fatigue, leukopenia, anemia, thrombocytopenia and elevation of GOT and GPT were observed relatively frequently. Among these, fatigue and thrombocytopenia were regarded as dose limiting factors.
