melphalan and Lung-Diseases--Interstitial

Whole lung irradiation (WLI) represents an important part of multimodal therapy in Ewing sarcoma (EwS) patients diagnosed with pulmonary metastases. This review discusses pulmonary toxicity in EwS patients with pulmonary metastases treated with WLI, who received different modes of high-dose chemotheray (HD-Cth).. Literature was compiled using the Cochrane Library, PubMed database, and the National Institute of Health (NIH) clinical trials register. Relevant patient information, including nature of HD-Cth, acute and late lung toxicities, and pulmonary function disorders, was selected from the above databases.. Nine reports with a total of 227 patients, including 57 patients from a single randomized trial were included in this review. No acute or chronic symptomatic pulmonary toxicities were observed in patients that received WLI after HD busulfan-melphalan (HD-Bu/Mel), but 8% of these patients were diagnosed with asymptomatic restrictive lung disease. Grade 1 or 2 acute or chronic lung adverse effects were observed in up to 30% of patients that received WLI after HD treosulfan/Mel (HD-Treo/Mel) or HD etoposide (E)/Mel. Interstitial pneumonitis was present in 9% of patients treated concurrently with E/Mel and total body irradiation (TBI) with 8 Gy. Radiation doses as well as time between HD-Cth and WLI were both identified as significant risk factors for pulmonary function disorders.. The risk of adverse lung effects after WLI depends on several factors, including cumulative radiation dose and dose per fraction, HD-Cth regimen, and time interval between HD-Cth and WLI. A cumulative radiation dose of up to 15 Gy and a time interval of at least 60 days can potentially lead to a reduced risk of pulmonary toxicities. No evident adverse lung effects were registered in patients that received simultaneous therapy with HD-Cth and TBI. However, pulmonary function testing and lung toxicity reports were lacking for most of these patients.

The purpose of this study was to develop a high-dose chemotherapy (HDC) and peripheral blood stem cell (PBSC) regimen for treatment of patients with ovarian carcinoma that could be administered in an outpatient setting. Fourteen patients with advanced ovarian (n = 9) or breast (n = 5) carcinoma, who had failed conventional chemotherapy, were entered into a dose-escalation trial to determine the maximum tolerated dose (MTD) of carboplatin that could be administered with fixed doses of melphalan (160 mg/m2) and mitoxantrone (50 mg/m2). Twenty-five additional patients were included in a phase II trial at the MTD. Two of two patients had grade 4 severe regimen-related toxicities (RRT), one fatal, at a dose level of 1600 mg/m2. Two of 29 patients (6.9%) treated at the MTD (carboplatin, 1400 mg/m2) died of RRT. All three patients who died of toxicity had a calculated AUC for carboplatin >30 mg/ml/min. Thirty-one patients with ovarian cancer who had failed chemotherapy were treated, 24 at the MTD. Fourteen of 20 patients (70%) with ovarian carcinoma with evaluable disease achieved a CR and seven (35%) are alive disease-free a median of 20 months (range, 7-26). Five of seven patients with ovarian cancer who had failed chemotherapy but were rendered clinically disease-free following surgery survive without progression a median of 13 months (range, 9-19). Eight of 16 (50%) platinum-resistant and 4/12 (33%) platinum-sensitive patients with ovarian cancer survive disease-free.

Reduced-intensity regimens (RIRs) are being used with increasing frequency in patients with non-Hodgkin's lymphoma (NHL) undergoing allogeneic transplantation. The impact of dose reduction on relapse and survival has not been extensively studied. We performed a retrospective analysis of 88 patients conditioned with conventional myeloablative regimens (CMRs) (n = 48) and an RIR (n = 40) of fludarabine 125 mg/m(2) and melphalan 140 mg/m(2). Compared with the patients receiving CMR, those receiving RIR were older, had more often failed autologous transplantation, and had more frequently received peripheral blood and unrelated donor transplants. Graft-versus-host disease prophylaxis was provided with cyclosporine + methotrexate +/- prednisone for the CMR and with cyclosporine + mycophenolate +/- methotrexate for the RIR. The relapse rate was significantly lower in the patients receiving CMR than in those receiving RIR (13% vs 28%; P = .05). The 1-year transplantation-related mortality rate was 33% for CMR and 28% for RIR (P = .40). Kaplan-Meier 2-year overall survival and progression-free survival were 52% and 46% for CMR versus 53% and 40% for RIR (P = not significant). Using cumulative incidence functions based on competing risks, univariate analysis, and treatment-related prognostic factors, we found that higher treatment intensity (P = .03; relative risk [RR] = 35%) and absence of previous autologous transplantation (P = .0007; RR = 20%) were associated with a lower relapse rate. Using a Cox univariate proportional hazards model, we found that chemosensitive disease at transplantation (P = .05; RR = 57%) and absence of previous autologous transplantation (P = .002; RR = 37%) were associated with improved survival. Our observation of similar survival in the patients receiving CMR and those receiving RIR confirms that RIRs are feasible alternatives for high-risk patients with NHL; however, the data suggest that reduced treatment intensity and previous autologous transplantation are associated with increased relapse.

A 57-yr-old woman with multiple myeloma received an autologous tandem transplant at a 4-month interval. She was conditioned twice with 225 mg/m2 melphalan. After the second transplant, interstitial pneumonitis (IP) ensued. The clinical course was life threatening and mechanical ventilation was required for 32 d. All attempts to identify an infectious agent failed. A presumptive diagnosis of idiopathic IP, possibly related to melphalan toxicity, was made. High-dose methylprednisolone administration led to rapid and durable improvement. Melphalan was employed for conditioning in the tandem setting with an interval of only 3-4 months between two courses or a dose elevation to 225 instead of 200 mg/m2, may have induced IP which responded favorably to methylprednisolone.

Causes of treatment-related death were studied amongst 138 patients with acute myeloid (n = 90) or lymphoblastic (n = 48) leukemia allografted from HLA-identical siblings in first (n = 107) or second (n = 31) remission after a conditioning regimen comprising 110 mg/m2 melphalan and 1050 cGy single-fraction total-body irradiation (TBI) prescribed as maximum lung dose. Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine (n = 78) or cyclosporine-methotrexate (n = 60). Eighty-one patients died of causes other than relapse 16-2917 days (median 77) after transplantation. The actuarial probability of non-relapse mortality was 62% at 5 years. The major primary causes of death were pneumonitis (n = 38, 47%), GVHD (n = 18, 22%), and sepsis (n = 11, 14%). Pneumonitis contributed to 42 of the deaths (52%), and its etiology was infective (n = 27), idiopathic (n = 14), or a combination of the two (n = 1). On multivariate analysis, GVHD prophylaxis with cyclosporine alone was associated with a higher overall toxic death rate. The use of cyclosporine alone and a low infused cell dose (<2.5 x 10(8) total nucleated cells/kg or <0.6 x 10(8) mononuclear cells/kg) were associated with a higher risk of death from pneumonitis. We conclude that the use of cyclosporine alone as GVHD prophylaxis is associated with increased transplant-related toxicity, and the addition of methotrexate and infusion of a higher number of cells decrease the incidence of fatal pneumonitis.
