Abstract
BACKGROUND Colorectal cancer (CRC) is the third most common cancer worldwide. Mortality for CRC is improving in high income countries, but in low and middle income countries, rates of disease and death from disease are rising. In Sub-Saharan Africa, the ratio of CRC mortality to incidence is the highest in the world. This study investigated the nature of CRC treatment currently being offered and received in Nigeria. METHODS Between April 2013 and October 2017, a prospective study of consecutively diagnosed cases of CRC was conducted. Patient demographics, clinical features, and treatment recommended and received was recorded for each case. Patients were followed during the study period every 3 months or until death. RESULTS Three hundred patients were included in our analysis. Seventy-one percent of patients received a recommended surgical operation. Of those that didn't undergo surgery as recommended, 37% cited cost as the main reason, 30% declined due to personal reasons, and less than 5% absconded or were lost to follow up. Approximately half of patients (50.5%) received a chemotherapy regimen when it was recommended, and 4.1% received radiotherapy when this was advised as optimal treatment. With therapy, the median overall survival for patients diagnosed with stage III and stage IV CRC was 24 and 10.5 months respectively. Overall, we found significantly better median survival for patients that received the recommended treatment (25 vs 7 months; P < .01). CONCLUSIONS A number of patients were unable to receive the recommended treatment, reflecting some of the burden of untreated CRC in the region. Receiving the recommended treatment was associated with a significant difference in outcome. Improved healthcare financing, literacy, training, access, and a better understanding of tumor biology will be necessary to address this discrepancy.

Abstract
Background Findings from studies on obesity and benign prostatic enlargement (BPE) have been inconsistent. With a previous study done in our facility showing no correlation between anthropometric indices of obesity and BPE, this study aimed at reevaluating the association between obesity and BPE using sonographic indices of abdominal/central obesity. Materials and Methods Ninety consenting subjects with clinically confirmed BPE had their height and weight [(to calculate body mass index (BMI)] as well as waist and hip circumference [to calculate waist-hip ratio (WHR)] done. The subcutaneous, preperitoneal, and visceral fat thicknesses (SFT, PFT, and VFT, respectively) of these subjects and their prostate volumes were measured on transabdominal Ultrasonography (USS). Transrectal USS was also done to measure the total prostate and transitional zone volumes. Data were analyzed using SPSS version 22. Results WHR and waist circumference correlated positively with SFT (r = 0.325, P = 0.002 and r = 0.370, P = 0.000, respectively) and PFT (r = 0.209, P = 0.048 and r = 0.313, P = 0.003, respectively). While BMI correlated positively (r = 0.23, P = 0.029) with transrectal transitional zone volume, all three sonographic indices of adiposity correlated negatively (SFT: r = -0.223, P = 0.035; PFT: r = -0.321, P = 0.002; VFT: r = -0.242, P = 0.021) with transrectal total prostate volume. In addition, PFT correlated negatively with transabdominal prostate volume (r = -0.222, P = 0.037) and transrectal transitional zone volume (r = -0.211, P = 0.046). Conclusion The relationship of BMI with transrectal transitional zone volume was a direct one, while that of SFT, PFT, and VFT with transrectal total prostate volume as well as PFT with transabdominal prostate volume and transrectal transitional zone volume was an inverse one.
