Background: Non-Hodgkin's lymphoma is an aggressive malignant disease in children and adolescents. Although it is the fourth most common malignancy in Saudi children as reported in Saudi cancer registry, less information is available about pediatric Non-Hodgkin lymphoma and its outcome in Saudi Arabia. Study Objectives: To provide demographic data, disease characteristics, treatment protocol, toxicity and outcome of treatment in children & adolescents with Non-Hodgkin's lymphoma treated at KFMC. This study will form base line for future studies about pediatric Non-Hodgkin's lymphoma in KFMC, which may help to improve outcome for children with cancer in Saudi Arabia. Study Patients and Method: We retrospectively analyzed 28 children and adolescents diagnosed to have Non-Hodgkin's lymphoma at KFMC between December 2006 and December 2013, followed-up through June 2014. Results: Of the 28 patients, 10 (35.7%) girls and 18 (64.3%) boys, the male-to-female ratio was 1.8; 1. The median age at time of diagnosis was 6.4 years old (range 2.0 to 13.0 years old). The majority of patients (64.3%) were aged between 5 and 12 years old. Burkitt's lymphoma BL/BLL was the most common pathological subtype (60.7%), and DLBCL was the second most common subtype (21.4%). Abdominal and Retroperitoneal involvement was the most common primary site (78.6%) including the ileocaecal region.

Mobark et al. 300 ically for the t (8; 14) (q24; q32) a characteristic genetic feature of Burkitt's Lymphoma was obtained from 21 patients, variant rearrangement was observed in 3/21 samples and complex chromosomes karyotype in addition to IGH/MYC rearrangement was observed in 2/21 samples. Those patients presented with very aggressive lymphoma and combined BM and CNS involvement. We use the French-American-British Mature B-Cell Lymphoma 96 Protocol (FAB LMB 96) for treatment fornewly diagnosed Mature B-Cell type NHL and high risk ALL CCG 1961 Protocol for lymphoblastic lymphoma and international Anaplastic Large Cell Lymphoma 99 Study Protocol for ALCL. The median follow-up in patients not experiencing an adverse event was 53.1 months. The estimated 3-year EFE and OS rates in the entire cohort of patients with newly diagnosed NHL treated in the KFMC were 85.2% and 89.2% respectively; Overall survival (OS) rate of patients with mature B-cell-NHL was 88.9%. Conclusion: The outcomes and survival in our small series appeared to be excellent compared with those reported in other international trials even though most of our patients presented in advanced stage of the disease. We feel that the importance of the current study is to document the relative distribution of various types of pediatric non-Hodgkin's lymphomas and age-specific distribution in different Histological subtypes.

Pediatric Non Hodgkin's Lymphomas

Pediatric non-Hodgkin lymphoma (NHL) is a diverse collection of diseases, and results from malignant proliferation of lymphoid cells and immune system. NHL involves throughout the body, but bone and primary central nervous system (CNS) lymphomas are its rare presentations. The incidence of NHL in childhood differs according to age and geographic area, but overall constitutes 8-10% of all malignancies in children between 5-19 years of age. The preferred pathologic and molecular biology classification for NHL is based on currently recognized histologic (morphologic), immunophenotypic, and genetic features, and their clinical presentation and course. The clinical manifestations of NHL in children depend on pathological subtype and primary sites of disease. Abdomen and mediastinum are the most frequent primary sites of involvement. Most centers use st. Jude staging system and diagnostic workup. Most patients present with advanced stage and systemic disease. According to pathophysiology of childhood NHL, treatment strategy is based on extent of dissemination and requires attention to emergent complications. Modern treatments have caused dramatic improvement in childhood NHL. We need well conducted international studies in all parts of the world to increase our knowledge to acieve better outcome and prevent late effects in children.

Background: In the modern era of chemotherapy, the outcome of pediatric non-Hodgkin lymphoma (NHL) continues to improve internationally. Limited data such as information on epidemiology and survival, however, are available in Asian countries. Methods: Children (≤15 years old) diagnosed with histologically proven NHL from 1998 to 2014 were retrospectively analyzed. Results: In total, 114 patients were enrolled; they were predominantly male (65.8%) and had advanced disease (stage III, IV; 71.9%). Of these, 22.8% had Burkitt lymphoma, 20.2% had diffuse large B-cell lymphoma, 21.1% had lymphoblastic lymphoma, 20.2% had large cell lymphoma, and 15.8% had peripheral T-cell lymphoma. Twenty-nine patients died, especially of uncontrolled disease (62.1%) and infection (20.7%). During a median follow up of 78.4 months, Kaplan-Meier 5 year event-free and overall survival rates were 71.5% AE 4.3% and 74.8% AE 4.1%, respectively, regardless of subtype. B symptoms (i.e. systemic symptoms of fever, night sweats, and weight loss that can be associated with both Hodgkin's lymphoma and non-Hodgkin's lymphoma) and advanced disease had a significant negative impact on 5 year survival. No other prognostic factor was found, but survival tended to have a negative correlation with age. Conclusions: Pediatric NHL is aggressive, with a high prevalence of peripheral T-cell lymphoma. The present treatment stratification seems to be effective compared with that used in developed countries.

To describe the patient demographics and outcome analysis in paediatric non-Hodgkin lymphoma (NHL) patients. An observational study. The Hematology/Oncology Unit of The Children's Hospital and Institute of Child Health, Lahore, from January 2012 till December 2014. Demographics including age, gender, histopathology, stage and outcome data, in biopsy proven NHL patients were analyzed. Burkitts/B Cell and Diffuse Large B Cell lymphoma patients were treated with MCP 842 Protocol while T/B-cell lymphoblastic lymphoma (LL) patients were treated with EURO-LB 02 protocol. Ninety-one patients were treated during the study period at CHL. Data was insufficient in 18 patients, so they were excluded from the study. Patients included were 73. Males were 53 (72.6%). Thirty-seven (50.7%) were 5-10 years of age, and 22 (30.1%) 10-16 years old. Abdominal mass was the commonest presentation seen in 32 (43.8%), lymphadenopathy in 27 (37%), intussusception in 5 (6.8%), while intestinal obstruction,...
Disease patterns of pediatric non‑Hodgkin lymphoma: A study from a developing area in Egypt
Molecular and Clinical Oncology, 2014
Non-Hodgkin lymphoma (NHL) accounts for 8-10% of all childhood cancers. NHL collectively represents various lymphoid malignancies with diverse clinicopathological and biological characteristics. In this study, we aimed to describe the epidemiological and clinicopathological characteristics and treatment outcomes of pediatric NHL patients treated at the Pediatric Oncology Unit of Zagazig University Hospital and the Benha Specialized Pediatric Hospital. We conducted a cross-sectional retrospective study by reviewing the medical records of 142 patients admitted with a diagnosis of NHL over a period of 8 years (February, 2004 to February, 2012) in these two Oncology Units. The age at presentation ranged between 2 and 15 years, with a mean ± standard deviation (SD) of 6.1±2.8 years and a male:female ratio of 1.7:1. Abdominal involvement was the most common presentation (73.2%). Burkitt's lymphoma (BL) was the most common NHL subtype (69%), followed by lymphoblastic lymphoma, diffuse large B-cell lymphoma and anaplastic large-cell lymphoma, accounting for 18.3, 10.6 and 2.1% of the cases, respectively. The majority of the patients (88.7%) had been diagnosed with advanced disease (Murphy stage III/IV). Complete remission was achieved in 120 cases (84.5%). A total of 16 patients (11.3%) succumbed to the disease during the first few months and 6 patients (4.2%) remained alive following relapse. The mean follow-up duration ± SD was 34.6±25.1 months (range, 3-84 months). The 5-year overall survival (OS) and event-free survival (EFS) rates were 88.7 and 85.1%, respectively. None of the clinical, epidemiological or pathological variables exhibited a statistically significant association with the OS or EFS. In conclusion, NHL occurs at a younger age, with a higher incidence of BL and advanced-stage disease. The outcome of NHL in our two centers was satisfactory, approaching the international rates.
