Burkitt lymphoma: The effect of age, sex and delay to diagnosis on treatment completion and outcome of treatment in 934 Patients in Cameroon.

INTRODUCTION: The role of age and sex in the presentation and outcome of endemic Burkitt lymphoma (BL) has not been studied recently. This study analysed these factors in 934 patients with BL who had received cyclophosphamide and intrathecal methotrexate as treatment. METHODS: Records of 934 children diagnosed with BL from 2004 to 2015 were obtained from our Paediatric Oncology Networked Database (POND) cancer registry. Age at diagnosis, sex, disease stage, time to diagnosis, delay in diagnosis, completion of treatment, rate of abandonment, and one-year survival rates were recorded and statistically analysed. RESULTS: The male to female ratio of 1.41 for the study population of 934. The median delay from onset of symptoms to diagnosis was 31 days. The St Jude stage distribution was I = 6.4%, II = 5.9%, III = 71.5% and IV = 16.2%. Significantly more patients presented with stage III disease in age groups 5-9 and 10-14 years than 0-4 years. The overall 1-year survival rate was 53.45%, respectively 77.1% for stage I, 67.9% for stage II, 55.1% for stage III and 32.4% for stage IV disease (p<0.001). There was no significant difference in survival by sex and age group. CONCLUSION: Patients aged under 5 years presented with less-advanced disease, but survival was not affected by age. Sex did not influence delay to diagnosis and overall survival. The long delay between the onset of symptoms and diagnosis emphasises the need for interventions to achieve an earlier diagnosis and a better survival rate.

Outcome of retinoblastoma treatment protocol in Cameroon as per SIOP-PODC recommendation for a low-income setting.

INTRODUCTION: The International Society of Paediatric Oncology-Paediatric Oncology in Developing Countries (SIOP-PODC) group recommended graduated-intensity retinoblastoma treatment for children in low- and middle-income countries with limited local resources. AIM: The aim was to improve outcome of children with retinoblastoma by means of a treatment protocol for low-income settings as recommended by the SIOP-PODC recommendation in Cameroon. METHODS: Children diagnosed with retinoblastoma between 2012 and 2016 were treated in two Baptist Mission hospitals in Cameroon, staging according to the International Retinoblastoma Staging System. Treatment included local therapy and combination chemotherapy (vincristine, cyclophosphamide, and doxorubicin) with or without surgery as per SIOP-PODC guidelines for low-income countries. Endpoint was survival at 24 months. Kaplan-Meier curves with log-rank (Mantel-Cox) chi-square (χ2 ) with respective p-values were prepared. RESULTS: Eighty-two children were included, of whom 79.3% had unilateral disease. The majority were males (61.0%) with median age 24 months (range 1-112 months; standard deviation [SD] 19). Limited disease was diagnosed in 58.5%, metastatic disease in 35.4%, and unknown stage in 6.1%. Overall survival (OS) was 50.0% at 24 months post diagnosis, but 68.8% for limited disease. Estimated cumulative survival at 24 months was 0.528 (standard error [SE] 0.056). Causes of death included disease progression/relapses (60.5%), neutropenic sepsis (15.9%), unknown causes (18.4%), unrelated infection (2.6%), and death post surgery (2.6%). Stage was significantly associated with OS (p < .001). CONCLUSION: Stage was the most significant factor for good OS and demonstrated the efficacy and feasibility of the SIOP-PODC-proposed management guidelines for retinoblastoma in a lower middle-income setting.

Essential oncology nursing care along the cancer continuum.

Oncology nurses are at the heart of tackling the increasing global burden of cancer. Their contribution is unique because of the scale and the diversity of care roles and responsibilities in cancer care. In this Series paper, to celebrate the International Year of the Nurse and Midwife, we highlight the contribution and impact of oncology nurses along the cancer care continuum. Delivering people-centred integrated care and optimal communication are essential components of oncology nursing care, which are often played down. More oncology nurses using, doing, and leading research will further show the key nursing impact on care as part of a team. The oncology nurse influence in saving lives through prevention and early detection of cancer is noteworthy. Supportive care, the central pillar of oncology nursing, enables and empowers people to self-manage where possible. Globally, oncology nurses make a great positive difference to cancer care worldwide; their crucial contribution throughout the continuum of care warrants the inclusion and promotion of nursing in every country's cancer strategy. 2020 is the year of the nurse: let us take this learning to the future.
