PURPOSE: To evaluate the efficacy of the combination of interferon alpha (IFN-α) and daily low-dose cytarabine (ara-C) in the treatment of patients with early chronic-phase chronic myelogenous leukemia (CML) (within 1 year of diagnosis). Improving the degree of hematologic and cytogenetic response in patients with Philadelphia chromosome (Ph)-positive CML may improve prognosis. Both IFN-α and ara-C induce cytogenetic responses as single-agent therapy in CML. PATIENTS AND METHODS: One hundred forty patients with Ph-positive early chronic-phase CML received subcutaneous injections of IFN-α 5 megaunits/m2 daily and ara-C 10 mg daily. Their median age was 46 years; 53% had good-risk disease, 33% had intermediate-risk disease, and 14% had poor-risk disease. Their results were compared with those of patients receiving IFN-α with or without intermittent ara-C (7 days/mo). RESULTS: A complete hematologic response (CHR) was achieved in 92% of patients. A cytogenetic response was seen in 74%: it was major in 50% (Ph-positive < 35%) and complete in 31% (Ph-positive 0%). With a median follow-up of 42 months, the 4-year estimated survival rate was 70% (95% confidence interval, 61% to 79%). Significant side effects included fatigue (43%; grade 3/4, 11%), weight loss (19%; grade 3/4, 11%), muscle and bone aches (20%; grade 3/4, 7%), oral ulcers (4%), diarrhea (6%), and neurologic changes (27%, grade 3/4, 6%). The median dose of IFN-α was 3.7 megaunits/m2 daily, mainly because of reductions for myelosuppression (70% of cases); the median ara-C dose was 7.5 mg daily. Prognostic risk groups were predictive for response to the IFN-α plus ara-C combination. The incidence of CHR was higher with IFN-α plus daily ara-C compared with IFN-α plus intermittent ara-C and IFN-α alone (no ara-C) (92% v 84% v 80%, P = .01), as were the incidences of cytogenetic response (74% v 73% v 58%; P = .003) and major cytogenetic response (50% v 38% v 38%; P = .06). The median time to achievement of major cytogenetic response was significantly shorter than that for previous IFN-α regimens (7 v 10 v 12 months; P < .01). However, with the present follow-up, the survival and time to blastic transformation were similar. CONCLUSION: The combination of IFN-α plus daily low-dose ara-C seems to be promising for the treatment of CML. High rates of CHR and cytogenetic response were observed with acceptable toxicity and a lower daily dose of IFN-α compared with our previous studies.

Published: February 2017

PURPOSE: Because there are no data available from randomized controlled trials (RCT), a decision analysis was performed to aid in the decision of which option, a local excision with or without radiotherapy or an abdominal perineal resection (APR), should be offered to medically fit patients with early (suspected T1/T2) low (< 5 cm) rectal cancer. METHODS: All clinically relevant outcomes, including complications of surgery and radiotherapy, cure, salvageability after local recurrence, distant disease, and death, were modeled for both options. The probabilities of complications and outcomes after radiotherapy and/or local excision were derived from weighted averages of results from studies conducted between 1969 and 1997. The probabilities for the APR option were extracted from relevant RCTs. Long- and short-term patient-centered utilities for each complication and outcome were extracted from the literature and from expert opinion. RESULTS: The expected utility of local excision (EU = 0.81) for the base case was higher than the expected utility for APR (EU = 0.78). Although the result was sensitive to all variables, local excision was always favored over APR within the plausible ranges of the variables taken one, two, or three at a time. The model illustrated the tension between the patient's perception of a colostomy and the higher recurrence rates with local excision. CONCLUSION: The results of this decision analysis suggest that local therapy for early low rectal cancer is the preferred method of treatment. However, there must be careful preoperative assessment, patient selection, and consideration of patient concerns. In addition, decision analysis may be useful in providing patient information and assisting in decision making.

Published: February 2017

PURPOSE: A phase I clinical trial in patients with advanced carcinoma was conducted, using a replication-defective avipox vaccine containing the gene for the human carcinoembryonic antigen (CEA). The canarypox vector, designated ALVAC, has the ability to infect human cells but cannot replicate.PATIENTS AND METHODS: The recombinant vaccine, designated ALVAC-CEA, was administered intramuscularly three times at 28-day intervals. Each cohort of six patients received three doses of either 2.5 × 105, 2.5 × 106, or 2.5 × 107plaque-forming units of vaccine.RESULTS: The vaccine was well tolerated at all dose levels and no significant toxicity was attributed to the treatment. No objective antitumor response was observed during the trial in patients with measurable disease. Studies were conducted to assess whether ALVAC-CEA had the ability to induce cytolytic T-lymphocyte (CTL) responses in patients with advanced cancer. Peripheral blood mononuclear cells (PBMCs) from patients with the MHC class I A2 allele were obtained before vaccine administration and 1 month after the third vaccination. Peripheral blood mononuclear cells were incubated with the CEA immunodominant CTL epitope carcinoembryonic antigen peptide-1 and interleukin 2 and quantitated using CTL precursor frequency analysis. In seven of nine patients evaluated, statistically significant increases in CTL precursors specific for CEA were observed in PBMCs after vaccination, compared with before vaccination.CONCLUSION: These studies constitute the first phase I trial of an avipox recombinant in cancer patients. The recombinant vaccine ALVAC-CEA seems to be safe and has been demonstrated to elicit CEA-specific CTL responses. These studies thus form the basis for the further clinical exploration of the ALVAC-CEA recombinant vaccine in phase I/ II studies in protocols designed to enhance the generation of human T-cell responses to CEA.

PURPOSE: To evaluate the effect of ondansetron availability on the costs of managing nausea and vomiting. METHODS: We retrospectively assessed antiemetic costs (drug costs, nursing time, pharmacy time, physician's time, supplies, and facility “hotel” costs, in 1991 Canadian dollars) for all patients who received moderately or highly emetogenic chemotherapy from 6 months before to 6 months after ondansetron became commercially available in September 1991. We compared the costs for treating patients who received ondansetron versus those who received other antiemetic regimens, the costs for treating patients in the 6 months before versus the 6 months after ondansetron commercial availability, and the costs for treating patients in the first 4 months versus the last 4 months of the study period. RESULTS: We found no cost differences for patients treated with ondansetron versus other antiemetic regimens. However, there was a significant reduction in emesis management costs for patients treated after versus before the availability of ondansetron: for patients treated in the last third versus first third of the study period, there was a decrease in cost per patient per month of treatment of $374 (95% confidence interval, $243 to $505). These savings were achieved through a reduction in hospital bed days and other costs associated with the prevention and more effective management of nausea and vomiting. At the same time, the number of patients who received emetogenic chemotherapy and their average age increased, presumably because of the better control of gastrointestinal toxicity. CONCLUSION: Ondansetron availability has been associated with changes in the clinical management of cancer patients receiving chemotherapy and with overall cost savings compared with previously available antiemetic therapy.

PURPOSE: To use a standardized videotape stimulus to assess the effect of physician compassion on viewers' anxiety, information recall, treatment decisions, and assessment of physician characteristics. PARTICIPANTS AND METHODS: One hundred twenty-three healthy female breast cancer survivors and 87 women without cancer were recruited for this study. A randomized pretest/posttest control group design with a standardized videotape intervention was used. Participants completed the State-Trait Anxiety Inventory (STAI), an information recall test, a compassion rating, and physician attribute rating scales. RESULTS: Women who saw an “enhanced compassion” videotape rated the physician as warmer and more caring, sensitive, and compassionate than did women who watched the “standard” videotape. Women who saw the enhanced compassion videotape were significantly less anxious after watching it than the women in the other group. Nevertheless, information recall was relatively low for both groups, and enhanced compassion did not influence patient decisions. Those who saw the enhanced compassion videotape rated the doctor significantly higher on other positive attributes, such as wanting what was best for the patient and encouraging the patient's questions and involvement in decisions. CONCLUSION: The enhanced compassion segment was short, simple, and effective in decreasing viewers' anxiety. Further research is needed to translate these findings to the clinical setting, where reducing patient anxiety is a therapeutic goal.

PURPOSE: To determine the side effects of and response to pentostatin in patients with T-cell lymphomas with cutaneous manifestations. PATIENTS AND METHODS: Pentostatin was administered to 28 patients who had relapsed cutaneous T-cell lymphoma or peripheral T-cell lymphoma with prominent cutaneous disease. The starting dose was between 3.75 to 5.0 mg/m2/d intravenous for 3 days every 3 weeks. RESULTS: Of the 24 patients assessable for response, 17 (71%) achieved a partial remission (46%) or complete remission (25%). The patients had a median number of three (range, one to 12) prior therapies. Of the 86 courses of pentostatin given, 39 were administered at doses of 5.0 mg/m2/d and 30 at doses of 3.75 mg/m2/d. Dose escalation to 6.25 mg/m2/d was possible in only five courses, and toxicity necessitated dose reduction to 2.8 mg/m2/d in 12 courses. The most common side effects were granulocytopenia, nausea, and nonneutropenic fever. Most patients developed significant lowering of CD4 counts. Herpes zoster was seen within 1 year after pentostatin in five patients (19%). CONCLUSION: Pentostatin is an active agent in heavily pretreated T-cell lymphomas with cutaneous manifestations.

PURPOSE: The absolute risk of myelodysplastic syndrome (MDS) after autologous bone marrow transplant (ABMT) for non–Hodgkin's lymphoma (NHL) exceeds 5% in several reported series. We report the outcome of a large cohort of patients who developed MDS after ABMT for NHL.PATIENTS AND METHODS: Between December 1982 and December 1997, 552 patients underwent ABMT for NHL, with a uniform ablative regimen of cyclophosphamide and total body irradiation followed by reinfusion of obtained marrow purged with monoclonal antibodies. MDS was strictly defined, using the French-American-British classification system, as requiring bone marrow dysplasia in at least two cell lines, with associated unexplained persistent cytopenias.RESULTS: Forty-one patients developed MDS at a median of 47 months after ABMT. The incidence of MDS was 7.4%, and actuarial incidence at 10 years is 19.8%, without evidence of a plateau. Patients who developed MDS received significantly fewer numbers of cells reinfused per kilogram at ABMT (P = .0003). Karyotypes were performed on bone marrow samples of 33 patients, and 29 patients had either del(7) or complex abnormalities. The median survival from diagnosis of MDS was 9.4 months. The International Prognostic Scoring System for MDS failed to predict outcome in these patients. Thirteen patients underwent allogeneic BMT as treatment for MDS, and all have died of BMT-related complications (11 patients) or relapse (two patients), with a median survival of only 1.8 months.CONCLUSION: Long-term follow-up demonstrates a high incidence of MDS after ABMT for NHL. The prognosis for these patients is uniformly poor, and novel treatment strategies are needed for this fatal disorder.

PURPOSE: A three-step phase I/II trial associating accelerated radiotherapy with carbogen (step 1, ARCO), with nicotinamide (step 2, ARN), or with both (step 3, ARCON) was conducted, the aim of which was to overcome the effects of proliferation and hypoxia as potential causes of tumor radioresistance in glioblastoma multiforme. PATIENTS AND METHODS: Radiotherapy consisted of 60 Gy delivered over 4 weeks in 1.5-Gy fractions twice daily, 5 days a week. Carbogen breathing was started 5 minutes before each fraction and continued until the end of each treatment session. Nicotinamide was given daily as a single oral dose of 85 mg/kg. RESULTS: A total of 115 patients with a median age of 55 years were registered. Of 107 eligible patients, 23 were registered in step 1, 28 in step 2, and 56 in step 3. The planned treatment was administered without any interruption in 72% of patients (86% in ARCO but 68% in ARN and ARCON). The incidence and severity of acute skin and mucous membrane toxicity were higher in patients who received nicotinamide (ie, the ARN and ARCON groups). Grade 1 to 2 gastrointestinal toxicity was observed in 44% of patients in the ARN group and 32% of patients in the ARCON group, but only in 8% of patients in the ARCO group. Eight percent of evaluated patients presented with abnormal liver test results at treatment completion. The dose of corticosteroids had to be increased in 44% of patients. Late neurologic side effects were similar in all treatment steps and were observed mostly in patients with disease progression. Median survival times for patients treated with ARCO, ARN, and ARCON were 10.1, 9.7, and 11.1 months, respectively. CONCLUSION: Feasibility of ARCO treatment was good but that of ARN and ARCON was only fair. This probably reflected the higher acute toxicity rate, particularly gastrointestinal, for patients receiving nicotinamide. The dose of corticosteroids had to be increased frequently during treatment, suggesting a higher than expected acute neurologic toxicity. Overall survival was similar in the three treatment steps and not different when compared with results of other series that used radiotherapy alone.

Published: February 2017

PURPOSE: This multicenter phase II trial investigated the efficacy and toxicity of a combination of the novel intracellular histamine antagonist, N,N-diethyl-2-[4-(phenylmethyl)phenoxy]ethanamine.HCl (DPPE), and doxorubicin in patients with anthracycline-naïve metastatic breast cancer. Preclinical models and early single institutional studies suggested DPPE could potentiate the cytotoxicity of doxorubicin.PATIENTS AND METHODS: Forty-two women, 32 to 77 years old (median, 59 years), with anthracycline-naïve metastatic breast cancer were treated. Patients may have had one previous regimen of nonanthracycline chemotherapy, either in the adjuvant or metastatic disease treatment setting. DPPE (6 mg/kg) was administered as an 80 minute intravenous infusion with doxorubicin (60 mg/m2) given intravenously over the last 20 minutes of the DPPE infusion. Patients were premedicated with an antiemetic and sedating regimen. The DPPE/doxorubicin treatment was given every 21 days for a maximum of seven cycles.RESULTS: All 42 patients were assessable. Overall, toxicity was comparable to that expected with doxorubicin alone, with the exception of DPPE-related motion sickness, mild hallucinations, and cerebellar signs at the time of the infusion. These CNS side effects were manageable in an ambulatory care setting, improved with subsequent cycles of treatment, and did not usually require hospitalization. Four patients developed febrile neutropenia. Thirty-five patients received four or more cycles of chemotherapy. The overall response rate was 52.5% (95% confidence interval, 36% to 68%), with 9.5% complete responses (n = 4), 43% partial responses (n = 18), and 38% of patients with stable disease (n = 16).CONCLUSION: The antitumour effects of DPPE/doxorubicin the 52.5% response rate seems encouraging, particularly in consideration of the fact that a recently reported randomized National Cancer Institute of Canada Clinical Trials Group trial using single-agent doxorubicin 60 mg/m2in one of the treatment arms achieved a 31% response rate. Thus, a randomized phase III trial of doxorubicin versus doxorubicin plus DPPE is being conducted in this clinical setting.

PURPOSE: To compare first-line high-dose chemotherapy (HD-CT) with autologous blood stem-cell transplantation to standard-dose chemotherapy (SD-CT) in male patients with advanced germ cell tumors (GCTs), a matched-pair analysis was performed within a homogenous group of patients classified as having either Indiana advanced disease or a poor prognosis according to International Germ Cell Cancer Consensus Group (IGCCCG) criteria. PATIENTS AND METHODS: A multivariate analysis was performed that included 147 consecutive patients who had received sequential high-dose cisplatin, etoposide, and ifosfamide (VIP) therapy (HD-CT) in a German multicenter trial between 1993 and 1997 and 309 patients who had been treated with standard-dose cisplatin, etoposide, and bleomycin (PEB) or VIP chemotherapy (SD-CT) within two randomized trials at Indiana University between 1984 and 1992. RESULTS: Multivariate analysis demonstrated HD-CT to be significantly superior to SD-CT when adjustments were made for prognostic factors (P = .021). Primary tumor site (mediastinal v retroperitoneal/gonadal, P = .035) and presence of visceral metastases (P = .0004) were shown to be significant prognostic factors for overall survival. On the basis of these factors, as well as on tumor marker levels (good, intermediate, or poor, according to IGCCCG criteria), 146 of 147 HD-CT patients were fully matched to an SD-CT patient. Median follow-up was 21 months (range, 0 to 70 months) for the HD-CT patients and 22 months (range, 0 to 90 months) for the SD-CT patients. Two-year progression-free survival (75% v 59%) and overall survival (82% v 71%) were significantly prolonged in HD-CT patients (P = .0056 and P = .0184, respectively). CONCLUSION: The results indicate that first-line HD-CT in patients with poor-prognosis GCT may result in a significant improvement of progression-free and overall survival as compared with SD-CT. Salvage HD-CT seems not to compensate this survival advantage.
Clinical Trial to Assess the Relative Efficacy of Fluorouracil and Leucovorin, Fluorouracil and Levamisole, and Fluorouracil, Leucovorin, and Levamisole in Patients With Dukes' B and C Carcinoma of the Colon: Results From National Surgical Adjuvant Breast and Bowel Project C-04

PURPOSE: To compare the efficacy of leucovorin-modulated fluorouracil (FU+LV) with that of fluorouracil and levamisole (FU+LEV) or with the combination of FU+LV and levamisole (FU+LV+LEV). PATIENTS AND METHODS: Between July 1989 and December 1990, 2,151 patients with Dukes' B (stage II) and Dukes' C (stage III) carcinoma of the colon were entered onto National Surgical Adjuvant Breast and Bowl Project protocol C-04. Patients were randomly assigned to receive FU+LV (weekly regimen), FU + LEV, or the combination of FU+LV+LEV. The average time on study was 86 months. RESULTS: A pairwise comparison between patients treated with FU+LV or FU+LEV disclosed a prolongation in disease-free survival (DFS) in favor of the FU+LV group (65% v 60%; P = .04); there was a small prolongation in overall survival that was of borderline significance (74% v 70%; P = .07). There was no difference in the pairwise comparison between patients who received FU+LV or FU+LV+LEV for either DFS (65% v 64%; P = .67) or overall survival (74% v 73%; P = .99). There was no interaction between Dukes' stage and the effect of treatment. CONCLUSION: In patients with Dukes' B and C carcinoma of the colon, treatment with FU+LV seems to confer a small DFS advantage and a borderline prolongation in overall survival when compared with treatment with FU+LEV. The addition of LEV to FU+LV does not provide any additional benefit over and above that achieved with FU+LV. These findings support the use of adjuvant FU+LV as an acceptable therapeutic standard in patients with Dukes' B and C carcinoma of the colon.
