Liposomal-entrapped doxorubicin: an active agent in AIDS-related Kaposi's sarcoma.
Authors: Harrison M , Tomlinson D , Stewart S 
Published: February 2017

PURPOSE A phase II study was performed of single-agent liposomally entrapped doxorubicin ([LED] Doxil; Liposome Technology Inc, Menlo Park, CA) against locally advanced cutaneous/systemic AIDS-related Kaposi's sarcoma (KS). PATIENTS AND METHODS Thirty-four patients with AIDS-related advanced cutaneous/systemic KS were treated with 20 mg/m2 of LED every 3 weeks on an outpatient basis. The median age was 39 years and the median Karnofsky score was 70. All patients had poor prognostic disease as judged by AIDS Clinical Trials Group (ACTG) criteria. Nineteen of 34 patients had received prior chemotherapy for KS, although no patient had received prior anthracyclines. RESULTS An overall response rate of 73.5% (25 of 34) was observed. Partial responses (PRs) occurred in 67.7% (23 of 34) and complete responses (CRs) in 5.8% (two of 34). In patients who had received previous chemotherapy, the response rate was 68.4% (13 of 19), and all responses were PRs. The median time to response was 6 weeks. The median duration of response was 9 weeks. Toxicity according to World Health Organization (WHO) criteria was as follows: neutropenia (grade > or = 3), 34%; alopecia (grade 1 only), 9%; and nausea and vomiting (grade 1), 18%. One patient died of heart failure, which was not considered to be anthracycline-induced. CONCLUSION LED appears to be highly active against AIDS-related KS. The major toxicity is neutropenia, which seems to be progressive in patients who receive several cycles of therapy. Comparative studies of LED versus conventional chemotherapy are needed.

PURPOSE AND METHODS High-dose therapy with autologous stem-cell support has become common treatment for relapsed or refractory lymphomas. We conducted a study of 178 patients with Hodgkin's disease and 149 patients with non-Hodgkin's lymphoma who received high-dose therapy with stem-cell support. We evaluated the following: (1) whether improvements in outcomes over time found for surgical procedures were also true for a new nonsurgical procedure, autologous bone marrow and peripheral stem-cell transplantation; and (2) whether such a relationship, if it existed, applied to both clinical and economic outcomes. RESULTS Mortality rates for patients with Hodgkin's disease decreased from 20% in 1987 to 0% in 1991. For non-Hodgkin's lymphoma, the mortality rate decreased from 29% in 1987 to 4% in 1991. Multivariate analyses indicated that the number of previous transplants was the most important factor associated with survival and low-cost care. After controlling for differences in clinical factors, a logistic regression model predicted that patients with Hodgkin's disease had a 20% chance of dying after 30 cases and a 5% chance after 178 cases; patients with non-Hodgkin's disease had a 33% chance of dying after 14 cases and a 5% chance after 149 cases. For patients with Hodgkin's disease, the cost decreased at a rate of 10% per year from 1987 to 1991 (P = .001), while for patients with non-Hodgkin's lymphoma, the cost of transplants decreased at a rate of 8% per year. CONCLUSION Survival rates improved and costs of care decreased over time for patients who received high-dose therapy with stem-cell support. These changes are most likely related to improvements in supportive care technologies, better patient selection, and experience of the transplant team.

PURPOSE To evaluate the significance of molecular marker-positive cells in a cohort of non-Hodgkin's lymphoma (NHL) patients undergoing high-dose chemotherapy and autologous peripheral-blood stem-cell transplantation (PBSCT). PATIENTS AND METHODS Twenty-eight PBSC transplants have been performed in 24 patients with poor-prognosis NHL. Molecular analysis of the t(14;18) (q32;q21) translocation (bcl-2/immunoglobulin [Ig] heavy-chain joining locus [JH] fusion) or antigen receptor gene rearrangements was performed to determine the presence of lymphoma cells at presentation, in PBSC harvests, and before and after autologous PBSCT. Kaplan-Meier estimates of survival and Cox regression analyses were used to test the effect of bone marrow involvement, tumor-cell contamination of PBSCs, disease stage, and chemotherapy sensitivity at transplantation, and presence of marker-positive cells post-PBSCT on disease-free and overall survival. RESULTS Thirteen of 24 patients (54%) are alive following PBSCT at a median follow-up time of 654 days (range, 193 to 1,908). Nine patients are in complete remission (CR) at day 216 to 1,799 (median, 805) and four are alive following relapse (day 440, 573, 1,188, and 1,908). Eleven patients (46%) have died: three of transplant-related complications at day 0, 1, and 13, and eight of recurrent disease (day 132 to 1,330; median, 451). Longitudinal marker studies post-PBSCT showed that of 16 relapse events, 13 (81%) were positive for the lymphoma marker at or before clinically documented relapse. Marker studies became negative post-PBSCT in nine of nine patients who entered and remained in CR. Disease-free survival (DFS) was significantly shortened in patients in whom marker-positive cells were detected in serial samples posttransplantation (P = .006). Cox regression analysis showed that patients in this group had a 24 times higher risk of relapse (P = .03). CONCLUSION The results show that the reappearance or persistence of marker-positive cells after autologous PBSCT is strongly associated with relapse.

PURPOSE Although survival rates have improved for patients with bulky and advanced-stage Hodgkin's disease (HD), current treatments entail substantial acute morbidity and risks for late effects such as infertility, second malignancies, and cardiopulmonary toxicities. A novel, brief chemotherapy regimen (doxorubicin, vinblastine, mechlorethamine, vincristine, bleomycin, etoposide, and prednisone [Stanford V]) was designed to shorten the duration of treatment, significantly reduce cumulative doses of alkylating agents, doxorubicin, and bleomycin, and maintain dose-intensity (DI). This brief chemotherapy was combined with radiation therapy (RT) to bulky disease sites. METHODS Since May 1989, 65 previously untreated patients were treated for stage II HD with bulky mediastinal involvement (n = 21) or for stage III or IV HD (n = 44). Patients received weekly chemotherapy for 12 weeks. Consolidative RT was given to the first 25 patients to sites of initial bulky disease or radiographic abnormalities that persisted after chemotherapy; in the remaining 40 patients, RT was limited to bulky disease (adenopathy > or = 5 cm and/or macroscopic splenic nodules defined by computed tomography [CT]). RESULTS With a median follow-up period of 2 years, actuarial 3-year survival rate is 96% and failure-free survival (FFS) rate is 87%. The 3-year FFS rate is 100% for stage II patients with bulky mediastinal disease and 82% for patients with stage III to IV disease. There were no treatment-related deaths. In a preliminary analysis on a subset of patients, female and male fertility appears to be preserved. CONCLUSION These preliminary results indicate that the Stanford V chemotherapy regimen with or without RT is well-tolerated and effective therapy for bulky, limited-stage, and advanced-stage HD. Less cumulative exposure to alkylating agents, doxorubicin, and bleomycin and limited use of radiation is expected to decrease risks for second neoplasms and late cardiopulmonary toxicity. Based on these results, the Stanford V chemotherapy with or without RT regimen deserves further study in the context of a randomized clinical trial.

PURPOSE Hemorrhagic cystitis (HC) after bone marrow transplantation (BMT) has been ascribed to cyclophosphamide metabolites. HC has also been associated with excretion of the BK type of polyomavirus. The relative contributions of cyclophosphamide metabolites and BK virus in the development of HC following BMT are unknown. PATIENTS AND METHODS We conducted a randomized trial to compare mesna with forced diuresis for prophylaxis against HC in 147 BMT recipients. We studied the association of BK virus with HC in 95 consecutive BMT recipients by prospectively monitoring urinary excretion of BK virus using polymerase chain reaction amplification of viral gene sequences. RESULTS HC occurred in 37 of 147 (25.2%) transplant recipients. The incidence of HC was similar in patients given mesna (26.8%, 19 of 71) or forced diuresis (23.7%, 18 of 76), and in recipients of allogeneic (27.2%, 18 of 64) or autologous marrow (22.9%, 19 of 83). The incidence of HC was unrelated to primary disease, preparative regimen, or occurrence of graft-versus-host disease (GVHD). Excretion of BK virus was demonstrated in 50 of 95 patients (52.6%); 38 patients (40%) had persistent BK viruria (> or = two consecutive positive samples). HC occurred in 19 of 38 patients (50%) with persistent BK viruria, in one of 12 (8.3%) with only a single urine sample positive for BK virus, and in none of 45 who did not excrete BK virus (P < .0001). Shedding of BK virus also had a strong temporal correlation with onset of HC (r = .95). CONCLUSION Mesna and forced diuresis are equally effective in abrogating the urothelial toxicity of preparative regimens for BMT. Since HC after BMT is virtually always associated with persistent BK viruria, strategies aimed at the prevention or elimination of viruria in BK seropositive recipients are warranted.

PURPOSE A randomized trial was performed to investigate the ability of the nucleoside transport inhibitor dipyridamole (DP) to enhance the antitumor activity of fluorouracil (5-FU)/leucovorin (folinic acid [FA]). PATIENTS AND METHODS One hundred eighty-one untreated patients with advanced colorectal cancer were randomized to receive 5-FU 600 mg/m2 plus FA 300 mg/m2 on days 2 to 4 with or without DP 75 mg orally three times daily on days 1 to 5. Cycles were repeated every 3 weeks. Only patients with documented tumor progression before therapy were eligible. 5-FU pharmacokinetics using high-performance liquid chromatography (HPLC) were assessed in 11 nonrandomized patients receiving paired cycles with or without DP. RESULTS One hundred seventy-four patients were assessable for toxicity and response. There was no significant difference in toxicity, except DP-related headache in 24% of patients. An objective response rate of 15% (one complete response [CR] and 13 partial responses [PRs]) for 5-FU/FA and 13% (two CRs and nine PRs) for 5-FU/FA/DP was observed. The dose-intensity of 5-FU delivered was significantly higher (1.09- to 1.16-fold) for the DP-containing arm. Pharmacokinetic parameters of 5-FU did not differ significantly, except for a prolonged half-life (t1/2) induced by DP. The median time to progression (P = .8) and the median survival time (11.6 months for 5-FU/FA v 9.3 months for 5-FU/FA/DP; P = .14, log-rank test) were not different between treatment arms. CONCLUSION Orally administered DP did not improve the antineoplastic activity of 5-FU/FA in patients with advanced colorectal cancer when used at this dose and schedule. The observed increase in 5-FU dose-intensity for FU/FA/DP was not clinically relevant.

PURPOSE To describe in patients with small-cell lung cancer (SCLC) the characteristics of those who survive for > or = 5 years, to identify long-term prognostic factors, to analyze survival data of 5-year survivors, and to study 10-year survival in patients entered before 1981. PATIENTS AND METHODS A total of 1,714 unselected patients with SCLC were treated with combination chemotherapy in nine consecutive clinical trials from 1973 to 1991. All medical records were reviewed and follow-up data obtained to analyze and compare pretreatment and posttreatment characteristics. RESULTS Sixty patients survived longer than 5 years. Late relapses occurred in 15.0% of 5-year survivors and secondary malignancies in 20.0%. Twenty-six patients are still alive and disease-free 5 to 18 years (median, 9.5 years) from initiation of treatment. Extensive-stage disease, performance status (PS) more than 2, liver and bone marrow metastases, and elevated lactate dehydrogenase (LDH) and alkaline phosphatase levels were all negative prognostic factors. The 5-year survival rate was 3.5% (limited-stage disease, 4.8%; extensive-stage disease, 2.3%), and the 10-year survival rate was 1.8% (limited-stage disease, 2.5%; extensive-stage disease, 1.2%). CONCLUSION Long-term survival can be achieved for both stages of SCLC, but without any change in survival rates over the last decade. Long-term survivors continuously seem to have considerable mortality due to late relapses and secondary malignancies, especially tobacco-related cancers and other tobacco-related diseases.

PURPOSE Here we report the results of a phase III study, to evaluate whether the addition of cisplatin to radiation therapy (XRT) would improve progression-free survival or overall survival for patients with locally advanced unresectable non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Two hundred forty patients with biopsy-proven unresectable NSCLC without distant metastases or lower-stage medically inoperable patients were randomized to one of two treatment arms. Arm A consisted of thoracic XRT alone, 60 to 65 Gy total tumor dose in daily fractions of 1.80 to 2.00 Gy; and arm B consisted of identical XRT with the addition of cisplatin 70 mg/m2 every 3 weeks for three cycles beginning on the first day of irradiation. RESULTS Two hundred fifteen patients were eligible and assessable. The overall response rate was 50% on the combination arm versus 38% on the XRT-alone arm (P = .076). The median progression-free survival time was 23 versus 22 weeks, respectively (P = .0537). The median survival time was 43 weeks on the combination arm versus 46 weeks on the XRT arm (Poverall = .3469). The 1-, 2-, and 5-year survival rates were 43%, 18%, and 5% on the combination arm versus 45% 13%, and 2% on the XRT arm, respectively. CONCLUSION Cisplatin, administered every 3 weeks, does not significantly improve response rate, progression-free survival, or overall survival when added to thoracic XRT for locally advanced unresectable NSCLC.

PURPOSE We sought to compare three doxorubicin-based therapies for metastatic breast cancer for response frequency, time to treatment failure (TTF), and survival. MATERIALS AND METHODS Women with metastatic breast cancer who had measurable disease, required laboratory tests, had received no prior chemotherapy for metastases, had a Cancer and Leukemia Group B (CALGB) performance status < or = 2, and provided informed consent were eligible. Treatment included the following: arm I--cyclophosphamide, doxorubicin, and fluorouracil (CAF); arm II--vinblastine, doxorubicin, thiotepa, and halotestin (VATH); and arm III--VATH alternating with cyclophosphamide, methotrexate, fluorouracil, vincristine, and prednisone (CMFVP) on cycles 3, 5, 7, 9, etc. Doses were modified for toxicities. Standard CALGB response and toxicity criteria were used. RESULTS Between August 1982 and February 1987, 497 women were entered and 491 were treated on study. Pretreatment characteristics were well balanced and the median follow-up duration was 79 months. There were no significant differences in response (complete [CR] plus partial [PR]) at 50% on arm I, 57% on arm II, and 51% on arm III. The median TTFs were 8, 8, and 9 months, respectively, in favor of arm III when compared with arm I (P = .028). The median survival times for treatment arms I, II, and III were 15, 17, and 17 months, respectively. After multivariate regression analyses, only estrogen receptors (ER), performance status, and number of metastatic sites influenced TTF and survival. Leukopenia was the most common grade 3 or 4 toxicity, occurring in 90%, 80%, and 92% of patients per arm, respectively. Lethal toxicities were seen in four, five, and six women, respectively. Overall, there were more grade > or = 3 toxicities on arm II than I, and most occurred on arm III (P = .02). CONCLUSION The VATH regimen appears similarly effective to the CAF regimen as initial therapy. Alternating CMFVP with VATH did not improve response rate or survival. After accounting for other variables, treatment arm was not related to outcome. New therapeutic regimens are still needed.

PURPOSE A phase II study of ifosfamide, carboplatin, and prolonged oral administration of etoposide (ICE) in patients with untreated extensive-disease (ED) small-cell lung cancer (SCLC) was conducted to assess toxicities, response, and median survival. PATIENTS AND METHODS Between July 1990 and August 1992, 35 patients were treated. ICE doses were ifosfamide 5 g/m2 by 24-hour continuous intravenous (CIV) infusion with mesna on day 1, carboplatin 300 mg/m2 intravenously (IV) on day 1, and etoposide 50 mg/m2 orally on days 1 to 21 every 4 weeks for up to six to eight cycles (schedule I). Because of severe hematologic toxicity in the first 18 patients, the last 17 patients received ifosfamide 3.75 mg/m2 IV on day 1, carboplatin 300 mg/m2 IV on day 1, and etoposide 50 mg orally on days 1 to 14 (schedule II). RESULTS Nine of 18 patients (50%) on schedule I had 13 episodes of severe hematologic toxicity (one death), and only two (11%) received full doses on cycle 2. However, with schedule II, only four of 17 patients (24%) developed severe hematologic toxicity, and eight (47%) received full doses on cycle 2. Objective responses were observed in 29 of 35 patients (83%) (schedule 1, 16 of 18 patients [89%]; schedule II, 13 of 17 patients [76%]). There were eight (23%) complete responses (CRs) and 21 (60%) partial responses (PRs). The median survival duration was 8.3 months, and 1- and 2-year survival rates were 37% and 14%, respectively. CONCLUSION ICE with oral etoposide has comparable activity with other regimens in ED SCLC. However, the 2-year survival rate may be higher and ICE with the lower doses of schedule II could be given safely with acceptable toxicity. Further studies of ICE compared with standard two-drug regimens are warranted.

PURPOSE Recombinant human erythropoietin (r-Hu-EPO) is known to be effective in untreated cancer patients. Here we assess the possibility that r-Hu-EPO may also prevent or reduce anemia in patients who receive cytotoxic chemotherapy. METHODS Thirty-six patients with small-cell lung carcinoma (SCLC) were enrolled onto a three-arm, randomized trial to investigate the effect of r-Hu-EPO on hemoglobin (Hb) levels and RBC and platelet (Plt) transfusions during chemotherapy. Bone marrow progenitors were studied before and after treatment. Two groups of patients received r-Hu-EPO at a dose of either 150 IU/kg (group 150) or 300 IU/kg (group 300) three times per week for the duration of chemotherapy. A control group did not receive r-Hu-EPO (group O). A maximum of six cycles of a chemotherapy regimen that consisted of vincristine, ifosfamide, carboplatin, and etoposide (VICE) were given to all patients. Hematologic parameters were measured weekly, and RBC or Plt transfusions were given for Hb levels less than 9 g/dL and Plt counts less than 20 x 10(9)/L. RESULTS Hb levels decreased in all patients, but onset of anemia was delayed in groups that received r-Hu-EPO (P = .002). A total of 116 U RBC were transfused in group 0, 54 in group 150, and 52 in group 300 (P = .017). In addition, there was a nonsignificant trend toward higher Plt counts and fewer Plt transfusions in patients who received r-Hu-EPO. CONCLUSION r-Hu-EPO at a dose of either 150 or 300 IU/kg three times weekly delays the onset of anemia and reduces RBC transfusion requirements in patients who undergo intensive chemotherapy for SCLC. A possible effect of r-Hu-EPO on platelet numbers deserves further study.
