Head and neck diffuse large B cell lymphomas (HN-DLBCL) in human immunodeficiency virus (HIV) positive patients: long-term results in the highly active antiretroviral therapy (HAART) era

To report long-term outcomes and toxicity rates after chemotherapy (CHT) followed by radiotherapy (RT) in the highly active antiretroviral therapy (HAART) era in human immunodeficiency virus (HIV) positive patients with head and neck diffuse large B cell lymphomas (HN-DLBCL). Clinical data concerning consecutive HIV patients treated for DLBCL located in head and neck region with CHT and RT were retrospectively reviewed. Systemic treatment consisted of combination CHT agents given with concomitant HAART and regimen was left to oncologists' discretion. Involved field RT was delivered at a total dose of 30-36 Gy (2 Gy per fraction). Survival rates were estimated using the Kaplan-Meier method. Toxicity was evaluated using National Cancer Institute's Common Terminology Criteria for Adverse Events. Overall, 13 patients were included. There were no missing data. Eight patients had advanced disease (stage III-IV = 8; 61.5%). The most common primary tumor location was oral cavity (n = 7) with large mass at presentation. All patients completed the programmed treatment. Severe acute toxicity was observed in one patient, only. Overall, three patients had died and no treatment-related deaths occurred. After a median follow-up of 152 months, the 20-year overall survival and disease-free survival rates were 65.9 and 41.5%, respectively. Globally, there were no RT-related late complications. This data analysis suggested that CHT followed by RT can be safety proposed in the management of patients with HIV-related HN-DLBCL in the HAART era. Further investigations are necessary to validate our results

Radiation therapy in indolent primary cutaneous B cell lymphoma: a single institute experience

To report the clinical results after definitive radiotherapy (RT) for indolent primary cutaneous B cell lymphoma (pcBCL). The data concerning all patients treated for indolent pcBCL with RT with a curative intent between 1992 and 2012 were reviewed. All cases were (re)classified according to the World Health Organization (WHO) guidelines. A total of 42 patients with biopsy-proven primary cutaneous follicle center lymphoma (pcFCL) and primary cutaneous marginal zone lymphoma (pcMZL) were included. The median follow-up is 9.5 years. Treatment with RT resulted in complete response (CR) in all patients. Eight patients showed one or multiple relapses confined to the skin. No in-field recurrences were observed. For the entire cohort, the 10-year relapse-free survival (RFS) and overall survival (OS) were 71.1% and 87.1%, respectively. Univariate (UA) and multivariate (MA) analysis revealed extra-trunk primary lesion (MA) and multiple lesions (UA) as unfavorable prognostic factors. The 5-year RFS rate for patients with trunk lesion was 89.4% versus 66.9% for those with other location (p = 0.02). The 5-year RFS rates were 83.5 and 57.1% in case of single and multiple lesions (p = 0.04). An excellent survival can be achieved with definitive RT in indolent pcBCL. Patients with multiple and extra-trunk primary cutaneous lesions probably warrants intensification of therapy. Prospective studies are mandatory

Anorectal function and quality of life after chemoradiotherapy in patients with canal carcinoma

Background A retrospective study was conducted to evaluate sphincter function and quality of life (QoL) in patients treated with radiotherapy and concurrent chemotherapy (CRT) for anal canal cancer. Materials and Methods From 1998 to 2010, patients with anal canal cancer treated with CRT were eligible. Radiation dose was 59.4 Gy (1.8 Gy/ fraction) and the chemotherapy regimen was 5-fluorouracil and mitomycin C. Anorectal function was investigated by anorectal manometry and transrectal ultrasound. QoL was assessed with the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C29 questionnaire. Correlations between diagnostic parameters and patient-reported outcomes were evaluated. Results Eighteen patients were enrolled. Overall, 4 patients had stage I disease, 8 stage II and 6 stage III. Anorectal manometry parameters were significantly lower compared to healthy scores. Patients-reported continence was significantly higher than fecal incontinence manometry scores. Ultrasound sphincter complex defects were recorded in 17 patients. Globally, a positive correlation was described between resting pressure of manometric exam and sexual functioning items and sphincter complex and patient-reported flatulence, respectively. Conclusions Definitive CRT represents the standard of care for anal canal cancer. Patients experienced low rates of fecal incontinence compared with results of diagnostic exams. Further studies are needed to better define toxicity and QoL after definitive CRT in anal canal cancer

Definitive weekly hypofractionated radiotherapy in cutaneous squamous cell carcinoma: response rates and outcomes in elderly patients unfit for surgery

The optimal definitive radiotherapy (RT) scheme in cutaneous squamous cell carcinoma (cSCC) remains controversial, especially in elderly patients

Treatment complications and long-term outcomes of total body irradiation in patients with acute lymphoblastic leukemia: A single institute experience

Abstract BACKGROUND: The aim of this study was to evaluate treatment-related toxicity and clinical outcomes of total body irradiation (TBI) in patients with acute lymphoblastic leukemia (ALL). PATIENTS AND METHODS: We performed a retrospective review of all patients with ALL who underwent TBI-based conditioning regimen at our Institution between 2000 and 2012. RESULTS: A total of 211 patients were included. The median follow-up was 40 months. The 5-year overall survival and disease-free survival were 64.7% and 62.8%, respectively. The 5-year overall survival rate for the 163 children was 67.6% (95% confidence interval=55-77%). Disease status at time of transplant did not improve disease-free survival. Gastrointestinal acute toxicity was the most common early side-effect (19.9%). Acute graft-versus-host disease was reported in 31 patients (14.7%). Main late toxicities were cataract induction (12.8%) and growth, gonadal and endocrine effects (36%). CONCLUSION: TBI-based conditioning regimen led to a high survival rate with remarkably low radiation-related toxicity, suggesting that TBI provides a feasible therapeutic option in patients with ALL

Second cancer incidence in primary mediastinal B-cell lymphoma treated with methotrexate with leucovorin rescue, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin regimen with or without rituximab and mediastinal radiotherapy. results from a monoinstitutional cohort analysis of long-term survivors

Our aim is to assess the incidence of second cancer in long-time surviving primary mediastinal B-cell lymphoma (PMBCL) patients treated with combined radiochemoimmunotherapy (standard methotrexate with leucovorin rescue, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin with rituximab and mediastinal radiation therapy at a dose of 30 to 36 Gy). For this purpose, 92 points were evaluated. After a median overall survival of 137 months (range 76-212), we recorded second cancer in 3 of 80 long-surviving patients (3.75%) with cumulative incidence of 3.47% at 15 years and 11% at 17 years, with a 17-year second cancer-free survival of 82%. We observed 2 papillary thyroid cancers with a standardized incidence ratio (SIR) of 7.97 and an absolute excess risk (AER) of 17. 84 and 1 acute myeloid leukemia (AML) with an SIR of 66.53 and an AER of 10.05. No breast cancer occurred. Although we should take into account the limits of the proposed statistical analysis, combined modality treatment was related to a significant SIR and AER for thyroid cancer and acute myeloid leukemia
