Prognostic Factors and Treatment Outcome of Pediatric Anaplastic Large Cell Lymphoma Treated at the Children Cancer Hospital Egypt.

INTRODUCTION: The aim of the current study is to report the epidemiologic data, response rate, treatment outcome, and overall survival of anaplastic large cell lymphoma (ALCL) patients during the 8-year period. PATIENTS AND METHODS: A retrospective study included all patients with newly diagnosed ALCL from July 2007 till December 2015. RESULTS: A total of 48 patients were enrolled. The majority (66.7%) were male individuals. Twenty-one patients (43.7%) were low stage I or II, whereas 27 (56.2%) had advanced stage III or IV. Two patients (4.2%) died during induction chemotherapy. Disease status at last follow-up showed 35 patients (72.9%) in complete remission, 5 (10.5%) relapse, and 5 disease progression. The median time to relapse was 17.2 months. Four patients (8.4%) were salvaged by high-dose chemotherapy ifosphamide, carboplatine, etoposide followed by autologous hematopoietic stem cell transplantation, whereas 5 (10.5%) died out of disease progression. The 5-year overall survival and event-free survival were 81.2% and 68.6%, respectively. Median FU period was 58.7 month. Multivariate analysis included age, sex, stage, and response to chemotherapy and showed no statistical significance. CONCLUSION: Treatment of ALCL according to the Children's Oncology Group ANHL 0131 protocol is well tolerated. The relapsing patient could be salvaged by high-dose chemotherapy and autologous hematopoietic stem cell transplantation.

Surgery in perforated pediatric intestinal lymphoma.

BACKGROUND: Perforation is the most common surgical complication in pediatric intestinal lymphoma. During operation, many surgical decisions are debatable. AIM: To assess the outcome of surgical management of perforated pediatric intestinal lymphoma. PATIENTS AND METHODS: This is a retrospective analysis of all pediatric patients (<18 years old) with intestinal lymphoma treated in our hospital between July 2007 and June 2017. Risk factors for perforation, type of management and outcome in cases of intestinal perforation were analyzed. RESULTS: The study included 240 patients with intestinal lymphoma. Perforation developed in 16 patients (6.7%) with a median age of 5.3 (range: 2.8-15.7) years. Most of the patients (92.5%) had Burkitt lymphoma. The ileum was the most common site of perforation (n = 10). Perforation occurred at presentation (n = 2), during induction (n = 10), during maintenance chemotherapy (n = 2), or at relapse (n = 2). Primary resection anastomosis was done in 12 patients. The resected specimen showed a viable tumor in ten patients. Wound infection (25%) and dehiscence (12.5%) were the most common postoperative complications. The 5-year overall and event-free survivals of patients with perforation were 78.6% and 71.4%, respectively, compared with 85.5% and 81.2% in non-perforated patients; the difference was not significant (p = 0.374 and p = 0.270, respectively). CONCLUSION: Perforation is not an adverse prognostic factor for survival in pediatric intestinal lymphoma patients. Primary resection anastomosis seems to be a safe option if complete tumor resection is feasible.
