The availability of uniform and precise criteria for disease evaluation, response to treatment, and clinical staging of Kaposi's sarcoma (KS) in individuals with the acquired immune deficiency syndrome (AIDS) would facilitate therapeutic trials in patients with this neoplasm. Recently, a group of oncologists conducting clinical trials in patients with AIDS-associated KS as part of a cooperative group established by the National Institute of Allergy and Infectious Diseases (NIAID) drafted such criteria. The criteria take into account the unique problems associated with the evaluation of patients with a disseminated cutaneous neoplasm in the setting of a systemic virus infection associated with immune deficiency. The recommendations include a standardized format for documenting the extent of KS on initial and subsequent evaluations, response definitions that include assessments of lesion nodularity and tumor-associated edema in addition to more traditional methods for evaluating tumor response, and a new staging system that includes extent of tumor, immune status, and other AIDS-related disease manifestations, akin to the tumor-node-metastasis (TNM) system used to stage other tumors. The adoption of standardized criteria for the evaluation of KS should prove useful for group trials and for other investigators involved in the treatment of this disease.

In this large phase III trial, the efficacy of DaunoXome was comparable to that of ABV. Response rates, time to treatment failure, and overall survival were similar on both treatment arms. DaunoXome is a safe and effective primary therapy for advanced AIDS-related KS.

By protecting against cumulative doxorubicin-induced cardiac toxicity, ICRF-187 permits significantly greater doses of doxorubicin to be administered to patients with greater safety.

We identified 105 patients with lymphoid neoplasia associated with the acquired immunodeficiency syndrome (AIDS) at the New York University Medical Center from 1981 through 1986: 89 had non-Hodgkin lymphoma; 13, Hodgkin disease; and 3, chronic lymphocytic leukemia. Immunophenotypic and antigen receptor gene rearrangement analysis showed the B-cell origin of all non-Hodgkin lymphomas studied and the clonal suppressor-cytotoxic T-cell subset origin of the chronic lymphocytic leukemias. We classified 69% of the non-Hodgkin lymphomas as high grade (small, noncleaved and large cell, immunoblastic-plasmacytoid) and 31% as intermediate grade (diffuse large cell). Each histopathologic category was correlated with distinct clinical features, including a statistically significant difference in median survival. Patients with Hodgkin disease had an atypical, aggressive clinical course, whereas patients with T-cell chronic lymphocytic leukemia had an indolent clinical course. These studies show the clinical, morphologic, and immunophenotypic spectrum of AIDS-associated lymphoid neoplasia, that the natural history of Hodgkin disease is altered in patients with AIDS, and support the Centers For Disease Control's recent revision in diagnostic criteria for AIDS to include intermediate-grade diffuse, aggressive non-Hodgkin lymphomas occurring in patients seropositive for human immunodeficiency virus.

Studies in animals suggest that the bispiperazinedione ICRF-187 can prevent the development of dose-related doxorubicin-induced cardiac toxicity. In a randomized trial in 92 women with advanced breast cancer, we compared treatment with fluorouracil, doxorubicin, and cyclophosphamide (FDC), given every 21 days, with the same regimen preceded by administration of ICRF-187 (FDC + ICRF-187). Patients were withdrawn from the study when cardiac toxicity developed or the cancer progressed. The mean cumulative dose of doxorubicin tolerated by patients withdrawn from study was 397.2 mg per square meter of body-surface area in the FDC group and 466.3 mg in the FDC + ICRF-187 group (no significant difference). Eleven patients on the FDC + ICRF-187 arm received cumulative doxorubicin doses above 600 mg per square meter, whereas one receiving FDC was able to remain in the study beyond this dose. Antitumor response rates were similar (FDC vs. FDC + ICRF-187, 3 vs. 4 complete responses; 17 vs. 17 partial responses; and 9.3 vs. 10.3 months to disease progression). Although myelosuppression was slightly greater in the FDC + ICRF-187 group, the incidence of fever, infections, alopecia, nausea and vomiting, or death due to toxicity did not differ between the groups. Cardiac toxicity was evaluated by clinical examination, determination of the left ventricular ejection fraction by multigated nuclear scans, and endomyocardial biopsy. In comparisons of the FDC group with the FDC + ICRF-187 group, clinical congestive heart failure was observed in 11 as compared with 2 patients; the mean decrease in the left ventricular ejection fraction was 7 vs. 1 percent when the cumulative dose of doxorubicin was 250 to 399 mg per square meter (P = 0.02), 16 vs. 1 percent at 400 to 499 mg (P = 0.001), and 16 vs. 3 percent at 500 to 599 mg (P = 0.003); and the Billingham biopsy score was 2 or more in 5 of 13 patients undergoing biopsy vs. none of 13 (P = 0.03). We conclude that ICRF-187 offers significant protection against cardiac toxicity caused by doxorubicin, without affecting the antitumor effect of doxorubicin or the incidence of noncardiac toxic reactions.
