Histopathologic spectrum of childhood tumours in a Tertiary Hospital: a ten-year review
Background: There has been a growing public health burden of childhood
tumours in low and middle income countries (LMICs) as the trend in
epidemiological transition continues to vary. Objective: The objective
of this report is to determine the spectrum of childhood tumours at a
tertiary hospital in Nigeria. Methods: A retrospective review of the
histopathology register over the period January 2006 to December 2015.
Results: The total paediatric tumour cases was 248, including 143
(57.7%) females and 105 (42.3%) males, aged 0 \u2013 12 years (mean
6.1years \ub1 3.97 SD). The age group 2 - 5 year cohort had the
highest prevalence of tumour. The predominant tumour based on tissue of
origin was epithelial neoplasms 88 (35.5%), vascular neoplasms 56
(22.6%), neural neoplasm 42 (16.9%), mesenchymal neoplasm 37 (14.9%),
germ cell neoplasm 13 (5.2%) and haematopoietic neoplasms 12 (4.8%).
Majority of the tumours were benign, 148 (59.7%) and malignant 100
(40.3%). The most predominant benign tumour was haemangioma 33 (13.3%)
and predominant malignant tumour was lymphoma 22 (8.9%). Conclusion:
Benign tumours remain the commonest neoplasm of children in this
hospital-based data. Development and implementation of a tumour
registry would provide a more comprehensive information

Case-Control Study of Body Size and Breast Cancer Risk in Nigerian Women
Previous studies have shown that weight is inversely associated with premenopausal breast cancer and positively associated with postmenopausal disease. Height has been shown to be positively correlated with breast cancer risk, but the association was not conclusive for premenopausal women. These previous studies were conducted primarily in Western countries, where height is not limited by nutritional status during childhood. The authors assessed the association between breast cancer and anthropometric measures in the Nigerian Breast Cancer Study (Ibadan, Nigeria). Between 1998 and 2009, 1,233 invasive breast cancer cases and 1,101 controls were recruited. The multivariate-adjusted odds ratio for the highest quartile group of height relative to the lowest was 2.03 (95% confidence interval (CI): 1.51, 2.72; P-trend < 0.001), with an odds ratio of 1.22 (95% CI: 1.14, 1.32) for each 5-cm increase, with no difference by menopausal status. Comparing women with a body mass index in the lowest quartile group, the adjusted odds ratio for women in the highest quartile category was 0.72 (95% CI: 0.54, 0.94; P-trend = 0.009) for premenopausal and postmenopausal women. Influence of height on breast cancer risk was quite strong in this cohort of indigenous Africans, which suggests that energy intake during childhood may be important in breast cancer development
