Treatment of Children With B-Cell Non-Hodgkin Lymphoma in a Low-Income Country
ABSTRACT An adapted LMB 96 derived protocol for B-cell non-Hodgkin lymphoma (NHL) was implemented at the pediatric oncology unit of the Children Welfare Teaching Hospital in Baghdad (Iraq) from 2000 to present. The purpose was to evaluate the feasibility and efficacy of this intensive therapeutic regimen in a limited resource country.
Patients <15 years of age with high grade B-cell NHL were included. A modified LMB 96 regimen was employed with a reduction of cyclophosphamide and methotrexate dosages due to inadequate laboratory facilities and supportive care.
Between 2000 and 2005, 261 children with non-lymphoblastic NHL were registered; 239 were eligible for the analysis. Two patients had stage I disease, 20 stage II, 179 stage III, and 38 stage IV. Fifty-two patients (22%) had bulky disease. Twelve children were assigned to therapeutic group A (low risk), 184 to group B (intermediate risk), and 43 to group C (high risk). One hundred and eighty-four patients (77%) had a complete response after the COP pre-phase. Sixty-nine patients (29%) died during treatment. Twenty-nine patients abandoned treatment. At 24 months, the overall survival rate of the entire patient population was 66% (CI 95%: 62.2-70.6) and the event-free survival rate 53.3% (CI 95%: 50.0-56.8).
The treatment schedule proved effective, but the treatment-related mortality due to infections and metabolic complications was very high owing to the limited supportive care available. The high rate of treatment abandonment was also an important cause of failure, especially for children living far away from the hospital.

ABSTRACT: Asia accounts for 60% of the world population and half the global burden of cancer. The incidence of cancer cases is estimated to increase from 6.1 million in 2008 to 10.6 million in 2030, due to ageing and growing populations, lifestyle and socioeconomic changes. Striking variations in ethnicity, sociocultural practices, human development index, habits and dietary patterns are reflected in the burden and pattern of cancer in different regions. The existing and emerging cancer patterns and burden in different regions of Asia call for political recognition of cancer as an important public health problem and for balanced investments in public and professional awareness. Prevention as well as early detection of cancers leads to both better health outcomes and considerable savings in treatment costs. Cancer health services are still evolving, and require substantial investment to ensure equitable access to cancer care for all sections of the population. In this review, we discuss the changing burden of cancer in Asia, along with appropriate management strategies. Strategies should promote healthy ageing via healthy lifestyles, tobacco and alcohol control measures, hepatitis B virus (HBV) and human papillomavirus (HPV) vaccination, cancer screening services, and vertical investments in strengthening cancer healthcare infrastructure to improve equitable access to services.BMC Medicine 01/2014; 12(1):3.

ABSTRACT: To describe the characteristics and clinical course of febrile neutropenia (FN) in pediatric patients admitted to a comprehensive cancer center in Jordan. This is a 6-month prospective observational study. Patients admitted with FN were identified. Patient demographics, duration since last chemotherapy, use of granulocyte colony-stimulating factor, presence of central lines, transfer to the intensive care unit, length of hospital stay, mortality, and the results of all cultures were recorded. One hundred and nine episodes for 88 patients were included, with a median age of 6 years (range, 1 to 19 y) and 55% were females. Median duration since last chemotherapy was 7 days (range, 1 to 33 d); median duration of hospital stay was 7 days (range, 1 to 81 d). Transfer to the intensive care unit was required for 11% of episodes, and there were no deaths. Positive cultures were reported in 18.4% episodes. Pathogens isolated were gram-positive organisms (50%), gram-negative organisms (20%), viral (25%), and fungal (5%). Positive blood cultures were significantly more in episodes with central lines compared with those with no central lines (P=0.04). FN episodes had favorable outcomes and were mostly associated with negative cultures. There were differences between the microbiologic profiles reported in this study, compared with what has been previously described.Journal of Pediatric Hematology/Oncology 07/2013; 35(8).

ABSTRACT: The demographic, clinical characteristics, and treatment groups of 33 children with diffuse large B-cell lymphoma (DLBCL) were recorded and analyzed among 1486 non-Hodgkin lymphoma (NHL) cases since 1972. The median age was 9.7 years (range 1.4–16.9) and male/female ratio was 24/9 = 2.6. Kaplan–Meier methods and logrank tests were used in treatment analysis. The frequency of DLBCL among 1486 NHL cases was 2.2%, however, the percentage was 9.3% in cases diagnosed after 2000. The event-free survival (EFS) and overall survival (OS) rates for 33 children were 61% and 65.1% at 5 years, respectively. The EFS and OS rates of low stage (stages I and II) disease decreased to lower level in advanced stage (stages III and IV) disease. Associated conditions and ages older than 14 years were found as poor prognostic factors in multivariate analysis. The survival rates in children with DLBCL need further improvement. This is mainly related with late referral of those children with advanced disease. The proper diagnosis and early referral is essential in these children for a better survival rate. The children with associated conditions and older children must be handled with care since these are found as poor prognostic factors.Pediatric Hematology and Oncology 08/2014; 31(6).
