PURPOSE To evaluate whether a novel antiestrogen, toremifene, has similar antiatherogenic effects as tamoxifen. PATIENTS AND METHODS Forty-nine postmenopausal patients with node-positive breast cancer were randomized in a trial that compared the effects of tamoxifen and toremifene on serum lipoproteins. Tamoxifen was given at 20 mg and toremifene at 60 mg orally per day for 3 years. Serum concentrations of apolipoprotein (apo) A-I, A-II, and B, and lipoprotein(a) [Lp(a)], cholesterol, triglyceride, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol were measured before and after 12 months of antiestrogen therapy. RESULTS Both antiestrogens significantly reduced serum total and LDL cholesterol and apo B levels. However, the response of HDL cholesterol to treatments was clearly different between the groups. Toremifene increased the HDL level by 14%, whereas tamoxifen decreased it by 5% (P = .001). As a consequence, both cholesterol-to-HDL and LDL-to-HDL ratios decreased more in the toremifene than tamoxifen group (P = .008 and P = .03, respectively). Toremifene also increased the apo A-I level (P = .00007) and apo A-I-to-A-II ratio (P = .018). Both tamoxifen and toremifene decreased the Lp(a) concentration significantly (change, 34% v 41%). CONCLUSION These results provide positive evidence that toremifene has antiatherogenic properties with potency to improve all lipoproteins that are associated with increased coronary heart disease (CHD) risk.

PURPOSE To evaluate, in a prospective multicentric study, the efficacy of a conventional salvage chemotherapy (dexamethasone, cisplatin, and cytarabine [DHAP]) versus high-dose chemotherapy (carmustine, etoposide, cytarabine, and cyclophosphamide [BEAC]) followed by autologous bone marrow transplantation (ABMT) in patients with aggressive non-Hodgkin's lymphoma (NHL) in clinical partial response (PR) after two thirds of a conventional front-line therapy. PATIENTS AND METHODS From August 1988 to August 1991, 286 patients with aggressive NHL were randomized in seven Italian institutions to receive fluorouracil, methotrexate, cytarabine, cyclophosphamide, doxorubicin, vincristine, and prednisone (F-MACHOP) or methotrexate with leucovorin, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (MACOP-B) as front-line therapy. Of the 286 patients enrolled onto the trial, 77 (27%) were considered in PR after two thirds of the front-line therapy, and 49 of 77 (64%) were randomized: 27 to receive DHAP chemotherapy and 22 to receive BEAC followed by ABMT. RESULTS The response after second-line treatment was as follows: in the DHAP group, four patients (15%) achieved a complete remission (CR), 12 (44%) remained in stable PR, and 11 (41%) showed progressive disease; in the ABMT group, three patients (14%) obtained a CR, 18 (82%) obtained a stable PR, and one (4%) progressed, with an overall response (CR + stable PR) of 59% and 96% (P < .001) in the DHAP and ABMT groups, respectively. The overall survival was 59% versus 73% and the progression-free survival (PFS) was 52% versus 73% in the DHAP and ABMT groups, respectively (P, not significant). The toxicity was mild, particularly in the ABMT group, and no treatment-related deaths occurred in either group. CONCLUSION Because of the small number of patients randomized, we were unable to determine whether ABMT or a standard salvage regimen (DHAP) is superior for PR patients. However, we confirmed that myeloablative treatment is a safe and well-tolerated procedure in this category of patients and this may enable us to evaluate its role as part of a front-line treatment in poor-risk NHL patients.
Chemotherapy in malignant pleural mesothelioma. A review.
Authors: Ong S T , Vogelzang N J 
Published: February 2017

PURPOSE AND DESIGN We reviewed the published literature of clinical studies in malignant pleural mesothelioma, including phase II trials of the newer antifolates and plant derivatives, as well as older single-agent and combination chemotherapy trials. We excluded trials with less than 15 patients, although we have mentioned smaller trials in the text to make a specific point, as well as ones that show promise. We have also included confidence intervals when cited in the original reports, or calculated them when absent. RESULTS No drugs have consistently induced a response greater than 20%. Higher response rates have been reported with detorubicin, high-dose methotrexate, and edatrexate at 26%, 37%, and 25%, respectively, but these have yet to be confirmed. Agents that produce response rates in 10% to 20% of patients include doxorubicin, epirubicin, mitomycin, cyclophosphamide, ifosfamide, cisplatin, and carboplatin. Combination chemotherapy trials do not demonstrate a consistently greater response rate than single-agent trials. However, the combination of doxorubicin, cisplatin, bleomycin, and mitomycin demonstrated a response rate of 44% (95% confidence interval, 27% to 63%), but this remains unconfirmed. Intrapleural therapy using interferon gamma, particularly for small-volume disease, shows promise. CONCLUSION The successful treatment of unresectable pleural mesothelioma awaits the discovery of active drugs. Recent trials of high-dose methotrexate and other antifolates are encouraging. Newer agents, including suramin, should be evaluated in phase II trials. Off-protocol combination therapy cannot be recommended over single-agent therapy, but studies that use combinations of the newer agents should be conducted.

PURPOSE To investigate and measure the metabolism of colorectal cancer liver metastases using 18F-fluorodeoxyglucose positron emission tomography (FDG PET), before and during the first month of chemotherapy. The findings were compared with tumor outcome conventionally assessed using changes in tumor size. PATIENTS AND METHODS Patients with colorectal cancer liver metastases were treated with fluorouracil (5FU) as a protracted venous infusion (300 mg/m2/d), with or without interferon-alpha 2b for two 10-week blocks separated by a 2-week break. Before and at 1 to 2 and 4 to 5 weeks on treatment, FDG PET scans were performed. Patients fasted, were injected intravenously with FDG (50 to 100 MBq), and scanned using a large-area positron camera; the image data was processed such that regions of interest could be identified. The results were expressed as a ratio of FDG uptake in the tumor and normal liver (T:L) or as a semiquantitative standardized uptake value (SUV). These measures were compared with the tumor dimensions measured on a computed tomographic (CT) scan performed at 12 weeks from commencement of chemotherapy. RESULTS Twenty patients were studied; however, two did not have assessable liver metastases. Objective partial responses were observed in 11 of 18 patients. A total of 27 metastatic lesions were assessable. Pretreatment T:L ratios and SUVs did not correlate with tumor response, although response was associated with lower 1- to 2-week (1.84 v 2.17; t=2.667; P < .02) and 4- to 5-week (1.36 v 2.28; t=5.02; P < .001) T:L ratios, and 4- to 5-week (3.57 v 4.95; t=2.492; P < .05) SUVs. Expressed as a percent of the baseline values of the T:L ratio, responding lesions had a greater reduction in metabolism (67% v 99%; t=7.53; P < .001). The 4- to 5-week T:L ratio was able to discriminate response from nonresponse both in a lesion-by-lesion and overall patient response assessment (sensitivity 100%; specificity 90% and 75%, respectively). CONCLUSION Positron emission tomography used to evaluate the uptake of FDG in tumors yields data that correlate with the antitumor effect of chemotherapy in patients with liver metastases from colorectal cancer.

PURPOSE To examine the short-term and long-term results of paclitaxel therapy in patients with advanced heavily pretreated, cisplatin-refractory ovarian cancer. PATIENTS AND METHODS The results of treatment for patients entered onto National Cancer Institute (NCI) Treatment Referral Center protocol 9103 at the Memorial Sloan-Kettering Cancer Center (MSKCC) were reviewed to evaluate toxicity, efficacy, and survival. RESULTS Of 46 individuals with measurable disease treated on the protocol at MSKCC, the objective response rate was only 4%. However, the 2- and 3-year survival rates for all 103 patients (including both measurable and nonmeasurable populations) entered onto this study at MSKCC were 18% and 11%, respectively. Twenty-one percent of patients received > or = six courses of paclitaxel, which suggests treatment-related stabilization of disease may have had a greater impact on the natural history of the malignancy than indicated by the objective response rate. CONCLUSION This experience supports the hypothesis that a more prolonged delivery of paclitaxel (ie, > six courses), a cell-cycle-specific cytotoxic agent with limited or no cumulative toxicity, may result in an improved therapeutic outcome in ovarian cancer. This concept will need to be tested in a randomized phase 3 clinical trial.

PURPOSE To define the prognostic factors in adult patients with locally controlled soft tissue sarcoma (STS) and to determine which patients should be considered for adjuvant treatment. PATIENTS AND METHODS Five hundred forty-six patients with a nonmetastatic and locally controlled STS, collected in a cooperative data base by the French Federation of Cancer Centers (FNCLCC) Sarcoma Group from 1980 and 1989, were studied. Histologic slides of all patients were collegially reviewed. Initial treatment consisted of complete tumor resection with amputation in only 4% of the patients. Adjuvant radiotherapy was administered to 57.9% and adjuvant chemotherapy to 31%. Relationships between tumor characteristics were analyzed, and univariate and multivariate analyses were performed using Cox models for the hazards rate of tumor mortality, development of distant metastasis, and strictly local recurrence. RESULTS Unfavorable characteristics with an independent prognostic value for tumor mortality were: grade 3 (P = 3 x 10(-10)), male sex (P = 1.5 x 10(-5)), no adjuvant chemotherapy (P = 5.4 x 10(-5)), tumor size > or = 5 cm (P = 3.8 x 10(-3)), and deep location (P = 4.6 x 10(-3)). Unfavorable characteristics for the development of distant metastasis were: grade 3 (P = 4 x 10(-12)), no adjuvant chemotherapy (P = 6.4 x 10(-4)), tumor size > or = 10 cm (P = 9.8 x 10(-4)), and deep location (P = 1.3 x 10(-3)). For the development of local recurrence, the unfavorable characteristics were: no adjuvant radiotherapy (P = 3.6 x 10(-6)), poor surgery (local excision) (P = 2 x 10(-4)), grade 3 (P = 7.6 x 10(-4)), and deep location (P = 10(-2)). Grade, depth, and tumor size were used to define groups of patients according to the metastatic risk. Adjuvant chemotherapy was beneficial in terms of overall survival and metastasis-free survival in grade 3 tumor patients only. Despite worse characteristics concerning tumor depth, tumor-node-metastasis (TNM) and American Joint Committee (AJC)/International Union Against Cancer (UICC) classifications and grade in patients with adjuvant radiotherapy, the latter experienced significantly fewer local recurrences than patients with no radiotherapy. CONCLUSION Grade, tumor depth, and tumor size could be used to select patients with a high metastatic risk, for which adjuvant chemotherapy could be beneficial.

PURPOSE To assess whether chemotherapy that includes drugs that cross the blood-brain barrier improves survival in primary CNS non-Hodgkin's lymphoma (PCNSL) when combined with radiotherapy. PATIENTS AND METHODS Thirty-four patients, with no evidence of human immunodeficiency virus type 1 (HIV-1) infection, were treated with the related chemotherapy regimens of carmustine (BCNU), vincristine, cytarabine, and methotrexate (BVAM; 12 patients), cyclophosphamide, doxorubicin, vincristine, and dexamethasone (CHOD)/BVAM (17 patients) and intensified CHOD/BVAM (five patients) between 1986 and 1994. The median age was 60 years (range, 16 to 73) and 47% had a performance status of 3 or 4 (Eastern Cooperative Oncology Group [ECOG]/World Health Organization [WHO]). Ten patients were treated with BVAM chemotherapy between 1986 and 1989, and subsequently 17 patients were treated with CHOD/BVAM (cytarabine 3 g/m2). Twenty of these 27 patients received whole-brain radiotherapy (craniospinal in four). RESULTS The complete response (CR) rate at the completion of chemotherapy was 63% for BVAM and 67% for CHOD/BVAM; more neutropenia occurred with CHOD/BVAM. The 5-year actuarial probability of survival of all 34 patients was 33% (95% confidence interval [CI], 14% to 52%), with so far only one recurrence after 2 years. Using multivariate analysis, age (P = .0005) and number of tumors at diagnosis (P = .0358) were prognostic factors. All five patients aged > or = 70 years died during or shortly after chemotherapy. Performance status was not an independent variable. CONCLUSION The BVAM or CHOD/BVAM regimens can be delivered despite neutropenia without significant treatment delay or dose reduction in patients less than 70 years of age. Further intensification of this type of chemotherapy is probably not possible with patients of this age, many of whom have a poor performance status.

PURPOSE During the last few years, the application of CD30 monoclonal antibodies has led to the identification of a new lymphoma entity, termed anaplastic large cell lymphoma (ALCL). This tumor includes four distinct histologic subtypes, among which the Hodgkin's-like/Hodgkin's-related one (ALCL-HL) shares morphologic and phenotypic features with Hodgkin's disease (HD). PATIENTS AND METHODS From September 1988 to October 1993, 90 ALCL patients were treated with third-generation chemotherapy regimens (either vincristine, cyclophosphamide, fluorouracil, cytarabine, doxorubicin, methotrexate with leucovorin, and prednisone [F-MACHOP] or methotrexate with leucovorin, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin [MACOP-B]) during the course of an Italian multicentric randomized trial on high-grade non-Hodgkin's lymphomas (HG-NHL). In particular, 47 patients had ALCL of the common type (ALCL-CT) and 43 ALCL-HL. Null phenotype was the most common (39.8%), while T-cell, B-cell, and hybrid forms accounted for 35.5%, 22.2%, and 2.5%, respectively. RESULTS Complete remission (CR) was achieved in 66 of 90 (73.5%) patients (33 of 47 [70%] with ALCL-CT and 33 of 43 [77%] with ALCL-HL). The majority of the patients in CR (56.5%) were alive and well at a median follow-up time of 38 months; no significant differences were observed between the two histologic groups, with the rate of complete responders being 49% and 65% in ALCL-CT and ALCL-HL, respectively. The probability of relapse-free survival (RFS), projected at 63 months, was 67% for ALCL-CT and 82% for ALCL-HL. The risk of lower CR and RFS rates was associated with the presence of bulky disease, advanced stage, and B symptoms. CONCLUSION The data of the present study confirm that ALCL responds to third-generation chemotherapy regimens similarly to other aggressive malignant lymphomas in terms of both CR and RFS rates.

PURPOSE The patterns of failure (local and/or regional v metastatic) have been determined for patients with prostate cancer and pretreatment prostate-specific antigen (PSA) levels > or = 20 ng/mL treated with radiation alone with the purpose to design appropriate multimodal treatments. MATERIALS AND METHODS One hundred twenty patients with pretreatment PSA levels > or = 20 ng/mL were treated with external-beam radiation alone between February 1988 and October 1993. They were arbitrarily divided by PSA levels, 20 to 29.9 ng/mL, 30 to 49.9 ng/mL, and > or = 50 ng/mL, and analyzed in terms of freedom from any failure (no evidence of biochemical disease [bNED], and PSA level < 1.5 ngm/mL and not increasing), as well as freedom from imaging evidence of distant metastasis (fdm). RESULTS There was no significant difference in short-term outcome by pretreatment PSA level, and thus all patients were pooled for analysis. At 4 years, 81% were fdm and 28% were free of any failure. This suggests that approximately 50% have recurred with local and/or regional disease or undetectable metastatic disease. Multivariate analysis indicated that low palpation stage and higher center of prostate dose were associated with better bNED survival. Multivariate analysis indicated that increasing stage and younger age are significantly associated with increasing distant metastasis. CONCLUSION Patients with pretreatment PSA levels > or = 20 ng/mL are not optimally treated by irradiation alone. The pattern of failure suggests improvement may come from systemic treatment of metastatic disease and high-dose radiation to improve locoregional disease. To evaluate this, we have begun a multimodal trial of chemohormonal therapy followed by extended-field irradiation.

PURPOSE To conduct a phase I and pharmacologic study of the new topoisomerase I inhibitor, 9-aminocamptothecin (9-AC). PATIENTS AND MATERIALS A 72-hour infusion of 9-AC was administered every 14 days to 48 solid-tumor patients at doses of 5 to 59 microg/m2/h without granulocyte colony-stimulating factor (G-CSF) and 47 to 74 microg/m2/h with G-CSF. RESULTS Without G-CSF, two of eight patients who received 47 microg/m2/h had dose-limiting neutropenia in their initial cycle, as did both patients who received 59 microg/m2/h (with a platelet count < 25,000/microL in one). With G-CSF, zero of seven patients treated with 47 microg/m2/h had dose-limiting neutropenia in their first cycle, while dose-limiting neutropenia occurred in six of 14 patients (with platelet count < 25,000/microL in five) entered at 59 microg/m2/h. Among 39 patients entered at > or = 25 microg/m2/h 9-AC with or without G-CSF, fatigue, diarrhea, and nausea/vomiting of grade 2 severity ultimately occurred in 54%, 30%, and 38%, respectively, while grade 3 toxicities of each type occurred in 8% of patients. Steady-state 9-AC lactone concentration (Css) increased linearly from 0.89 to 10.6 nmol/L, and correlated strongly with leukopenia ( r = .85). CONCLUSION The recommended phase II dose of 9-AC given by 72-hour infusion every 2 weeks is 35 microg/m2/h without G-CSF or 47 microg/m2/h with G-CSF support. Dose escalation in individual patients may be possible according to their tolerance.

PURPOSE The aims of the current study were to evaluate in patients with high-risk multiple myeloma (MM) the feasibility and usefulness of high-dose chemotherapy or chemoradiotherapy followed by hematopoietic stem-cell support with autologous peripheral-blood progenitor cells (PBPC) harvested after high-dose cyclophosphamide (HDCYC). PATIENTS AND METHODS Seventy-three patients with high-risk MM were entered onto the study. Before the procedure, all patients had received HDCYC to collect PBPC by leukapheresis. One patient died of infection after HDCYC. All other patients subsequently received high-dose melphalan (HDM) (140 mg/m2) either alone (n = 1) or associated with either busulfan (16 mg/kg; n = 4) or total-body irradiation (TBI) (8 to 15 Gy; n= 67). In addition, three of the latter patients received cyclophosphamide (120 mg/kg). Thereafter, PBPC were reinfused either alone in 61 patients or together with back-up bone marrow cells in 11 patients in whom the granulocyte-macrophage colony-forming unit (CFU-GM) cell content of the leukapheresis was low. RESULTS One patient died of acute cardiac failure after reinfusion of PBPC; three patients did not respond after autologous blood progenitor cell transplantation (ABPCT), while the other 68 patients achieved either a complete response (CR; n = 32) or partial response (PR; n = 36). Thirty-six patients relapsed or progressed after a median response duration of 14.5 months (range, 3 to 43) and 19 of these subsequently died. Four other patients died while still responsive of lung cancer (n = 1) or infection (n = 3). The remaining 28 patients are currently alive and still responding with a median follow-up duration of 27 months (range, 6 to 66). The 3-year probability of survival was 66% +/- 12% (95% confidence interval [CI] after ABPCT and 77% +/- 51% (95% CI) from diagnosis. CONCLUSION High-dose chemotherapy or chemoradiotherapy followed by autologous PBPC support in MM is feasible and efficient. Further studies are needed to confirm these encouraging, although preliminary, results and to compare this technique with other therapeutic strategies.
