Synergistic Toxicities from Multiple Therapies for Synchronous Malignancies.

ABSTRACT: Patients may present with multiple malignancies in the setting of particular environmental and occupational exposures. These patients often require combination systemic therapy, which has not yet been studied for concurrent use. While toxicities for specific chemotherapies and immunotherapies may be well known, the possibility of exaggerated toxicity due to combination therapy exists and is understudied. Several trials are underway that may shed further light on how combination therapies affect patient toxicity. This case report outlines the unfortunate development of severe edema and rash, refractory to traditional methods of management, from combining immunotherapy and chemotherapy.

Project description:PurposeTreatment strategies in palliation of pediatric cancer remain a significant challenge. In this study, we aimed to assess the efficacy and safety of a short course of hypofractionated radiation therapy (RT) for metastatic or recurrent childhood tumors.Methods and materialsA total of 104 lesions in 62 pediatric patients with metastatic or recurrent cancer were treated with a short hypofractionation schedule (>1 but ≤5 fractions; ≥3 Gy per fraction) between 2007 and 2017 in our institution. The primary endpoint was local control (LC). Other endpoints included treatment response, overall survival, progression-free survival, and toxicity. Toxicities were assessed using the Common Terminology Criteria for Adverse Events v.4.0.ResultsThe most common histologies were neuroblastoma, comprising 50 of the 104 lesions (48.1%); osteosarcoma, 17 lesions (16.4%); and Ewing sarcoma, 13 lesions (12.5%). A median total dose of 24 Gy was delivered in a median of 5 fractions. Of 104 lesions, 26 (25.0%) were treated with stereotactic body radiation therapy, 24 (23.1%) with intensity modulated RT, and 48 (46.2%) with 2-dimensional RT or 3-dimensional conformal RT. A complete or partial response was observed in 63 (60.6%) of lesions, and stable disease was observed in 34 (32.7%). At a median follow-up of 8.7 months, 21 local failures occurred (20.2%). The 1- and 2-year LC rates were 74% and 68%, respectively. LC was better for tumors without previous irradiation (83% vs 57% with previous RT; P = .004). LC rates did not differ between RT techniques or total biologically effective dose with α/β ratio of 10 (BED10) (≤30 vs >30 Gy). At the time of analysis, 38 deaths in the cohort of 62 patients (61.3%) were recorded. The 1-year progression-free survival and overall survival rates were 31% and 44%, respectively. Incidence of any grade ≥3 toxicity was 6.7% (7 of 104). No grade 5 events occurred.ConclusionsA short hypofractionation scheme yields effective disease control and treatment response with a favorable side effect profile. Select pediatric patients with symptomatic metastases or recurrent disease can be considered for a short course of palliative RT.
