In 139 patients with breast or lung carcinoma, malignant melanoma, and Hodgkin's or non-Hodgkin's lymphoma, JC and BK virus serology (hemagglutination inhibition) and urinary polyomavirus excretion (cytology and immunofluorescence microscopy) were studied. Overall, 18 of 70 patients with paired sera (26%) had titer increases against JC or BK virus, and 11 of 114 patients (10%) had evidence for urinary excretion. The infection rate was highest in patients with Hodgkin's or non-Hodgkin's lymphoma (approximately 40%). Serum HAI antibody titers against JC and BK viruses appeared similar to age-matched controls in each patient group--with the exception of decreased BK titers at diagnosis in patients with resected malignant melanoma and increased JC virus antibody titers at diagnosis in patients with poor-prognosis non-Hodgkin's lymphoma (IC-2). The biologic significance of these observations remains to be determined. Initial antibody titers against JC or BK virus were not of prognostic value for subsequent survival in any of the tested patient groups. Both nonspecific immunotherapy and aggressive, multidrug chemotherapy had surprisingly little effect on serum HAI titers to JC or BK virus. Patients with poor-prognosis non-Hodgkin's lymphoma appear especially suitable for further investigation of JC and BK virus infections. Study of nonbrain, nonurinary-tract tissues may disclose other parenchymal sites of polyomavirus replication in these patients.

Age-adjusted incidence rates for males and females for 36 cancer sites across 29 census sub-divisions of the province of Alberta were correlated with one another. It was hypothesized that cancers which vary together across geographical areas may have common aetiological factors. The correlations were measured by the Pearson product moment coefficient, r, and illustrated by scatter graphs and regression lines. For males moderate correlations were found between prostate and skin cancer and between prostate cancer and non-Hodgkin's lymphoma. Also moderately correlated were male stomach and small intestine cancers and cancers of the bladder and the buccal cavity and pharynx. Specific site correlations for cancers in females were generally higher than for cancers in males. The highest correlations were found between cancer of cervix (invasive) and cancer of trachea, bronchus and lung, between multiple myeloma and cancer of brain and nervous system, between acute lymphatic leukemia and cancer of the bone and connective tissue, and between melanoma and cancer of bone and connective tissue. Although all these correlations are moderate they nevertheless indicate substantial relationships. Possible common aetiologic factors for correlating pairs of cancers are discussed.

The clinical trials of bisantrene are still at an early stage. However, the many Phase II trials currently ongoing in the Southwest Oncology Group are too premature to draw any firm conclusions. However, there was general agreement during the discussion period that bisantrene does have definite clinical activity in certain tumors. These include metastatic breast cancer, non-Hodgkin's lymphoma, other types of lymphoma, leukemia, and, probably, ovarian cancer. There does not appear to be significant activity in malignant melanoma or in metastatic renal cancer. The conclusion of this symposium was that bisantrene is an active and reasonably well tolerated drug and that further trials are indicated.

Antibody-dependent cellular cytotoxicity (ADCC) mediated by peripheral blood monocytes was determined in 120 patients who had gastrointestinal tract (GIT), lung and breast cancer, melanoma, or Hodgkin's and non-Hodgkin's lymphoma. Results were expressed in terms of maximum cytotoxicity and cytotoxicity at E:T = 1:10 and were compared with the results obtained in 63 normal subjects. There was a significant decrease in maximal cytotoxicity for both the GIT cancer and the melanoma patient groups, but not for any of the other groups. These differences were not confirmed when results were expressed at low effector: target cell ratios, e.g., cytotoxicity at E:T = 1:10. The relationship between monocyte ADCC and disease extent was examined in those groups with sufficient numbers. Monocyte ADCC was higher in patients with GIT cancer of limited extent than in patients with extensive GIT cancer and in the control group.

4'-Epi-doxorubicin (4'e-Dx) was used as a single agent in a broad phase II study involving a variety of advanced metastatic tumors. A total of 115 patients were treated, of whom 93 were evaluable. The dosage was 75 mg/m2/cycle repeated every 21 days, with a maximal cumulative dose of 550 mg/m2. Nine responses were achieved in a total of 28 patients with breast cancer (32%). The response rate was 54% in breast cancer patients receiving 4'e-Dx as first-line treatment, 25% in patients previously given chemotherapy without doxorubicin, and 11% in patients previously given chemotherapy with doxorubicin. Some therapeutic activity was also detected in endometrial carcinoma, epidermoid carcinoma of the cervix, non-Hodgkin's lymphoma, melanoma, and skin epidermoid tumor, but the number of patients entered in the study with these various tumors was too limited to allow any statement on efficacy of 4'e-Dx. No treatment schedule with 4'e-Dx had to be interrupted because of toxicity. In a total of 373 evaluable cycles, only three acute reversible ECG abnormalities were recorded. In 16 of 109 evaluable patients there was some minor or moderate alteration of one or more of the three major blood cell parameters following 4'e-Dx therapy, requiring a postponement of the next cycle by less than or equal to 10 days.

A phase II trial was conducted to determine the clinical activity of amsacrine (m-AMSA) in patients with heavily pretreated solid tumors, myeloma, and lymphoma at the University of Arizona Cancer Center. Additionally, m-AMSA was evaluated at other Southwest Oncology Group institutions in breast cancer, myeloma, melanoma, and oat cell cancer of the lung. At a dose of 120 mg/m2 given iv every 28 days, 12 partial responses were observed in 221 patients evaluable for response. Some antitumor activity was observed in breast cancer (four responses of 65 patients), non-Hodgkin's lymphoma (three of nine), Hodgkin's disease (two of five), and sarcoma (two of 15). A partial response was also documented in one of two patients with cervical cancer. Among the 135 patients treated at the University of Arizona who were extensively evaluated for toxic effects, only myelosuppression and anemia were seen in a significant number of patients. At this dose and schedule, 29% of patients developed leukopenia of less than 3000 cells/mm3, 16% developed a thrombocytopenia of less than 100,000 cells/mm3, and 29% had an acute fall in hemoglobin of greater than or equal to 2 g/100 ml. In addition, two patients suffered grand mal seizures which were not clearly drug-related. These results suggest that further study of m-AMSA in lymphoma, sarcoma, and cervical cancer is warranted.

Eighty-one patients with a variety of refractory disseminated malignant neoplasms have been treated in the first multiple fixed-dose phase I trial of recombinant leukocyte A interferon (IFL-rA). Each patient received IFL-rA by intramuscular injection, three times weekly for 28 days. Dosages were escalated in different patients from 1 to 136 x 10(6) units per injection. The toxic reactions seen with IFL-rA resembled those of nonrecombinant leukocyte interferon and included fever, chills, fatigue, anorexia, myalgia, headache, occasional nausea and vomiting, and dose-dependent reversible leukopenia and hepatic transaminase elevations. The pharmacokinetics of IFL-rA were also comparable with nonrecombinant leukocyte interferon. Objective evidence of antitumor activity was seen in non-Hodgkin's lymphoma, chronic lymphocytic leukemia, Hodgkin's disease, breast cancer, and melanoma, indicating that IFL-rA, the first genetically engineered biological response modifier available for testing in cancer patients, is biologically active in vivo.

A potential application of the human tumor stem cell colony assay is to guide Phase II clinical investigations by identifying classes of tumors (or individual patients) which are sensitive in vitro to a new antitumor compound. We have tested human tumor stem cells from 140 tumor biopsies representing 20 different tumor types for chemosensitivity to the Phase II drug 4'-(9-acridinylamino)methanesulfon-m-anisidide. In vitro sensitivity was defined as a reduction in the number of tumor colony-forming cells to 30% of the control or less after a 1-hr exposure to one-tenth of the pharmacologically achievable plasma concentration of 4'-(9-acridinylamino)methanesulfon-m-anisidide. In vitro sensitivity was found in 29 cases: non-Hodgkin's lymphoma (2 of 2); cervical carcinoma (1 of 1); sarcoma (3 of 6); neuroblastoma (1 of 2); acute myelogenous leukemia (6 of 16); chronic myelogenous leukemia (1 of 3); melanoma (8 of 34); uterine carcinoma (1 of 5); lung carcinoma (1 of 9); ovarian carcinoma (4 of 36); and breast carcinoma (1 of 11). Prospective in vitro-in vivo correlations in eight patients with various tumor types showed that three of three patients sensitive in vitro to 4'-(9-acridinylamino)methanesulfon-m-anisidide responded in vivo, while five of five patients resistant in vitro had no clinical response. The results provide support for further evaluation of the utility of the human tumor stem cell colony assay for targeting Phase II clinical trials.

AMSA, an acridine derivative with significant antitumor activity in experimental tumors, was administered to 17 patients with advanced tumors refractory to standard chemotherapies. A phase I study was undertaken in 10 patients with solid tumors and lymphomas. Dose-limiting toxicity was myelosuppression. With a median dose of 90 mg/m2 (75-148 mg/m2), median lowest WBC count was 1,000/mm3 (100-3,200) on day 11 and its recovery up to 4,000/mm3 was seen on day 21, while lowest platelet count was 42 X 10(3)/mm3 (7-300 X 10(3) on day 12 and its recovery up to 100 X 10(3)/mm3 was on day 20. Non-hematological toxicities were nausea (39%), vomiting (11%) and phlebitis (17%) in 18 courses of therapy. The result indicated that the recommended dose schedule for a phase II evaluation was 90 mg/m2, every three weeks. Therapeutic activity was observed in patients with non-Hodgkin's lymphoma (one partial response and two minor responses out of four). Two out of five breast, one ovarian, and one melanoma patients showed stable diseases. Five leukemic patients (three AMLs, one MoL, and one blastic CML) were treated with AMSA, and in these cases cytoreduction of peripheral and bone marrow blasts was seen, but it was not adequate to induce remission. Further clinical trials with this agent are warranted, especially in patients with acute leukemia, lymphoma and breast cancer.

Vindesine (VDS) is an analogue of the vinca alkaloids. Its spectrum of antitumoral activity is similar to that of vincristine (VCR), but with milder experimental neurotoxicity, and it inhibits the polymerization of tubulin. Its terminal half-life is 24 h and its plasma clearance is intermediate between those of vinblastine (VLB) and VCR. The maximal tolerated dose is 4-5 mg/m2/week, the dose-limiting toxicity being myelosuppression (nadir by days 7-8 and recovery by days 11-13). It has already been demonstrated as efficient in childhood acute lymphoid leukemia (ALL), non-Hodgkin's lymphoma, blastic crisis of chronic myeloid leukemia, and esophageal carcinoma. It has also shown activity in Hodgkin's disease, breast and germ cell carcinomas, and melanoma. Intolerance is mainly neurologic, with paresthesias, without motor impairment, or hematologic, with leukopenia, and sometimes alopecia, asthenia, and muscle pains. The results are better if the patients have not been treated previously; continuous infusion could be of interest and there appears to be no cross-resistance with its parent VCR, as documented in ALL.
