RESUMO

BACKGROUND: The lipid profile and atherogenic risk indices in Nigerian breast cancer patients are largely unknown. This study evaluated the lipid profile and atherogenic risk indices of breast cancer patients in Nigeria. METHODS: This study involved 45 primarily diagnosed breast cancer patients and 50 normal control subjects. Total cholesterol, triglyceride, and High-density lipoprotein cholesterol (HDL-C) were measured. Low-density lipoprotein cholesterol (LDL-C) was calculated according to Friedewald formula. Atherogenic index of plasma (AIP), Atherogenic coefficient (AC), TC/HDL-C (Castelli I) and LDL-C/HDL-C (Castelli II) risk indices were all calculated. The Framingham risk assessment was calculated and categorized. RESULTS: The study group had significantly higher triglycerides (TG), and atherogenic indices than the control group (p < 0.001), while HDL-Cholesterol (HDL-C) was significantly lower in the study group (p < 0.001). Total cholesterol and LDL-Cholesterol (LDL-C) had a significant positive correlation with age (r = 0.283, p < 0.018; r = 0.272, p < 0.023); TG was significantly positively correlated with systolic and diastolic blood pressure (r = 0.320. p < 0.007; r = 0.334, p < 0.005); HDL-C had a significant negative correlation with BMI, systolic and diastolic blood pressure (r = -0.252, p < 0.035; r = -0.29, p < 0.015; r = -0.329, p < 0.005). The lipid ratios (TC/HDL-C, LDL-C/HDL-C) were significantly positively correlated with body mass index (BMI), systolic and diastolic blood pressure. The Framingham Risk Score showed that only 2 subjects in the study group (4.4%) were at a high risk of having a cardiovascular event. CONCLUSION: Breast cancer patients have a higher prevalence of dyslipidaemia, and cardiovascular risk than the normal population.

RESUMO

Objective: This cross-sectional study was conducted on the associations between body composition, energy expenditure and caloric intake among 45 Nigerian breast cancer patients. Methods: Forty-five Nigerian breast cancer patients were measured and analysed for their body composition, energy expenditure and caloric intake. Statistical analyses included a chi-square test, Student's t-test, paired t-test, Spearman correlation and linear regression using Statistical Package for the Social Sciences 23.0. Results: The body fat indices (body mass index (BMI), fat mass index (FMI), and body fats percentage) show that more than 50% of breast cancer patients were either overweight or obese. The Spearman correlation showed that fat-free mass (FFM) was the most strongly correlated with energy expenditure (r = 0.84). BMI and (FMI - fat mass in relation to height) were significantly correlated with the Harris-Benedict equation for energy expenditure (p < 0.001; p = 0.002), but they were not correlated significantly with the Karnofsky performance status. A paired t-test showed that caloric intake was significantly higher than total energy expenditure (p < 0.001). FFM was the best predictor of resting energy expenditure (REE). Conclusion: In conclusion, FFM remains the best predictor of REE. High body mass and high caloric intake indicate the need for support from nutritional programmes.

RESUMO

BACKGROUND: The estimated incidence of colorectal cancer is rising in Nigeria, where most patients present with advanced disease. Earlier detection of colorectal cancer is a goal of the Nigerian National Cancer Control Plan, but the utility of fecal-based screening is unclear. This study aimed to assess the fecal immunochemical test as a colorectal cancer screening modality in average-risk individualS in Nigeria. METHODS: A population-based, cross-sectional study of qualitative fecal immunochemical test-based colorectal cancer screening was done in asymptomatic, average-risk participants aged 45-75 years in three states in Nigeria (Osun, Kwara, and Lagos). Participants were invited to enrol using age-stratified and sex-stratified convenience sampling following community outreach. Exclusion criteria included a personal history of colorectal cancer or rectal bleeding in the previous 6 months, a first-degree relative with a known diagnosis of colorectal cancer, or a comorbidity that would preclude conscious sedation or general anesthesia. Participants with positive fecal immunochemical test results underwent colonoscopy, and the positive predictive value of fecal immunochemical testing for colorectal cancer and advanced adenomas (≥10 mm, tubulovillous or villous or high-grade dysplasia) was calculated. Data on demographics and acceptability of fecal immunochemical testing and colonoscopy were collected. FINDINGS: Between January and April 2021, 2330 participants were enrolled in the study and received a fecal immunochemical test, which was returned by 2109 participants. 1677 participants tested negative and 432 tested positive. Of these 432 participants, 285 underwent a colonoscopy (235 showed no polyps or cancer, 47 had polyps identified, and three had colorectal cancer identified). Of the 47 participants who had polyps identified, 20 had advanced adenomas diagnosed. The median age was 57 years (IQR 50-63), 958 (41%) were male and 1372 (59%) were female, and 68% had at least a secondary-level education. Participants were evenly spread across wealth quintiles. The positivity rate of the fecal immunochemical test was 21% overall (432 of 2109; 95% CI 20-21%), 11% (51 of 455; 95% CI 10-12) in Lagos, 20% (215 of 1052; 95% CI 20-21) in Osun, and 28% (166 of 597; 95% CI 27-29) in Kwara. Among the patients with a positive fecal immunochemical test who completed colonoscopy, the positive predictive value for invasive colorectal cancer was 1·1% (95% CI 0·3-3·3), and 7·0% (4·5-10·8) for advanced adenoma. The acceptability of fecal immunochemical screening among participants was very high. INTERPRETATION: Colorectal cancer screening with qualitative fecal immunochemical tests in Nigeria is feasible and acceptable to average-risk asymptomatic participants. However, the low positive predictive value for advanced neoplasia and high endoscopy burden investigating false positives suggests it might not be an appropriate screening tool in this setting.

RESUMO

AIM: To assess the relationship between nutritional status and inflammatory markers of breast cancer patients, and to identify predictors of malnutrition in these patients. METHODS: This is a cross-sectional study of 45 patients with breast cancer assessed between January and June 2018. Nutritional status was evaluated by objective and subjective methods. The inflammatory markers and inflammation-based scores evaluated were C-reactive protein (CRP), albumin, erythrocyte sedimentation rate (ESR), Glasgow Prognostic Score (GPS), CRP/albumin ratio, and Albumin/CRP ratio. RESULTS: A total of 45 patients were evaluated. Majority of the patients have high levels of both CRP and ESR (73.3% and 86.7% respectively). More than 70% of the patients were well nourished. There was no significant association between CRP (P = 0.067), ESR (P = 0.094) and SGA (Subjective Global Assessment) categories. Albumin (P < 0.001), Albumin/CRP ratio (P = 0.002), CRP/albumin ratio (P = < 0.001), and GPS (P < 0.001) were significantly associated with SGA categories. On multivariate analysis, albumin (P < 0.001), Albumin/CRP ratio (P = 0.004), CRP/albumin ratio (P = 0.009), GPS (P = 0.01), and ECOG (P = 0.009) were the only markers independently related to malnutrition. CONCLUSION: The inflammation-based scores were significantly associated with malnutrition and can be used as biochemical nutritional assessment tools in cancer patients.

RESUMO

OBJECTIVE: To describe the risk factors for late detection and advanced-stage diagnosis among patients who detected their BC early. METHOD: Using secondary data, we analyzed the impact of socio-demographic factors, premorbid experience, BC knowledge, and health-seeking pattern on the risk of late detection and advanced-stage diagnosis after early BC detection. Test of statistical significance in SPSS and EasyR was set at 5% using Sign-test, chi-square tests (of independence and goodness of fit), odds ratio, or risk ratio as appropriate. RESULT: Most socio-demographic factors did not affect detection size or risk of disease progression in the 405 records analyzed. High BC knowledge, p-value = 0.001, and practicing breast self-examination (BSE) increased early detection, p-value = 0.04, with a higher probability (OR 1.6 (95% CI 1.1-2.5) of detecting <2cm lesions. Visiting alternative care (RR 1.5(95% CI 1.2-1.9), low BC knowledge (RR 1.3(95% CI 1.1-1.9), and registering concerns for hospital care increased the risk of advanced-stage diagnosis after early detection (64% (95% CI 55-72)). Adhering to the monthly BSE schedule reduced the risk of advanced-stage diagnosis by -25% (95% CI -49, -1.1) in the presence of socioeconomic barriers. CONCLUSION: Strategies to increase BC knowledge and BSE may help BC downstaging, especially among women with common barriers to early diagnosis.

RESUMO

Understanding the molecular and phenotypic profile of colorectal cancer (CRC) in West Africa is vital to addressing the regions rising burden of disease. Tissue from unselected Nigerian patients was analyzed with a multigene, next-generation sequencing assay. The rate of microsatellite instability is significantly higher among Nigerian CRC patients (28.1%) than patients from The Cancer Genome Atlas (TCGA, 14.2%) and Memorial Sloan Kettering Cancer Center (MSKCC, 8.5%, P < 0.001). In microsatellite-stable cases, tumors from Nigerian patients are less likely to have APC mutations (39.1% vs. 76.0% MSKCC P < 0.001) and WNT pathway alterations (47.8% vs. 81.9% MSKCC, P < 0.001); whereas RAS pathway alteration is more prevalent (76.1% vs. 59.6%, P = 0.03). Nigerian CRC patients are also younger and more likely to present with rectal disease (50.8% vs. 33.7% MSKCC, P < 0.001). The findings suggest a unique biology of CRC in Nigeria, which emphasizes the need for regional data to guide diagnostic and treatment approaches for patients in West Africa.

RESUMO

Cancer incidence is rising in low- and especially middle-income countries (MIC), driven primarily by four high-burden cancers (breast, cervix, lung, colorectal). By 2030, more than two-thirds of all cancer deaths will occur in MICs. Prevention and early detection are required alongside efforts to improve access to cancer treatment. Successful strategies for decreasing cancer mortality in high-income countries are not always effective, feasible or affordable in other countries. In this review, we evaluate strategies for prevention and early detection of breast, cervix, lung, and colorectal cancers, focusing on modifiable risk factors and high-risk subpopulations. Tobacco taxation, human papilloma virus vaccination, cervical cancer screen-and-treat strategies, and efforts to reduce patient and health system-related delays in the early detection of breast and colorectal cancer represent the highest yield strategies for advancing cancer control in many MICs. An initial focus on high-risk populations is appropriate, with increasing population coverage as resources allow. These strategies can deliver significant cancer mortality gains, and serve as a foundation from which countries can develop comprehensive cancer control programs. Investment in national cancer surveillance infrastructure is needed; the absence of national cancer data to identify at-risk groups remains a barrier to the development of context-specific cancer control strategies.

RESUMO

Fourty-five breast cancer patients and 50 apparently healthy sex-matched controls from the University of Ilorin Teaching Hospital were enrolled in this study. Plasma D-dimer and fibrinogen were found to be significantly higher than controls; APTT was significantly shorter than the controls. D-dimer and fibrinogen were also significantly positively correlated with ECOG, disease stage, lymph node involvement, and tumor size. On multivariate analysis, D-dimer and fibrinogen were found to be independently related to lymph node involvement. This study shows that plasma D-dimer and fibrinogen levels are elevated in breast cancer patients, and both are markers of disease progression.

RESUMO

BACKGROUND/OBJECTIVE: Breast cancer (BC) mortality is exceptionally high in Africa due to late presentation and advanced-stage diagnosis. Previous studies examining barriers to early BC presentation are markedly inconsistent, showing conflicting findings within and between African regions, making resource allocation and designing interventional campaigns challenging. Our objective was to assess the strength or magnitude of the association between determinants/risk factors and delayed presentation/advanced-stage diagnosis of BC in Africa. METHODS: Electronic searches in PubMed, AJOL, Google, ResearchGate, ScienceDirect, and PubMed Central found eligible articles between 2000 and 2020. The meta-analytical procedure in Meta-XL used the quality effect model. I-squared (I2) above 75% indicated high heterogeneity. The summary effect size was the odds ratio with 95% confidence intervals. RESULTS: The effect of socio-economic and demographic determinants on delay varies across African regions. Low level of education (1.63, 95% CI 1.01-2.63), and not performing breast self examination (BSE) (13.59, 95% CI 3.33-55.4) were significantly associated with delayed presentation. Younger patients had more significant delays in West Africa (WA, 1.41, 95%CI 1.08-1.85), and the reverse occurred in North Africa (0.68, 95%CI 0.48-0.97). Lack of BC knowledge (1.59, 95% CI 1.29-1.97), not performing BSE, or no history of undergoing clinical breast examination (CBE) (2.45, 95% CI 1.60-3.40), were associated with advanced-stage disease at diagnosis. Older patients had significantly more advanced disease in WA, and the reverse occurred in South Africa. Aggressive molecular BC subtypes [Triple negative (OR 1.62, 95% CI 1.27-2.06) or HER2 positive (1.56, 95% CI 1.10-2.23)] were significant determinants of advanced-stage diagnosis. CONCLUSION: Promoting early presentation and reducing advanced-stage BC throughout Africa should focus on modifiable factors, including providing quality education, improving breast health awareness and BC knowledge, and developing strategies to increase BSE and CBE. Interventions targeting socio-demographic determinants should be context-specific.

RESUMO

BACKGROUND: The help-seeking interval and primary-care interval are points of delays in breast cancer presentation. To inform future intervention targeting early diagnosis of breast cancer, we described the contribution of each interval to the delay and the impact of delay on tumor progression. METHOD: We conducted a multicentered survey from June 2017 to May 2018 hypothesizing that most patients visited the first healthcare provider within 60 days of tumor detection. Inferential statistics were by t-test, chi-square test, and Wilcoxon-Signed Rank test at p-value 0.05 or 95% confidence limits. Time-to-event was by survival method. Multivariate analysis was by logistic regression. RESULTS: Respondents were females between 24 and 95 years (n = 420). Most respondents visited FHP within 60 days of detecting symptoms (230 (60, 95% CI 53-63). Most had long primary-care (237 of 377 (64 95% CI 59-68) and detection-to-specialist (293 (73% (95% CI 68-77)) intervals. The primary care interval (median 106 days, IQR 13-337) was longer than the help-seeking interval (median 42 days, IQR 7-150) Wilcoxon signed-rank test p = 0.001. There was a strong correlation between the length of primary care interval and the detection-to-specialist interval (r = 0.9, 95% CI 0.88-0.92). Patronizing the hospital, receiving the correct advice, and having a big tumor (> 5 cm) were associated with short intervals. Tumors were detected early, but most became advanced before arriving at the specialist clinic. The difference in tumor size between detection and arriving at a specialist clinic was 5.0 ± 4.9 cm (95% CI 4.0-5.0). The hazard of progressing from early to locally advanced disease was least in the first 30 days (3%). The hazard was 31% in 90 days. CONCLUSION: Most respondents presented early to the first healthcare provider, but most arrived late at a specialist clinic. The primary care interval was longer than the help-seeking interval. Most tumors were early at detection but locally advanced before arriving in a specialist clinic. Interventions aiming to shorten the primary care interval will have the most impact on time to breast cancer presentation for specialist oncology care in Nigeria.

RESUMO

PURPOSE: The prevalence of themes linked to delay in presentation of breast cancer (BC) and their underlying factors vary considerably throughout Africa. Regional differences and trends are largely unreported. The purpose of this research was to provide summary estimates of the prevalence and distribution of the themes and underlying factors linked to delay in the presentation of BC, regional variation, and trends in an effort to identify targets for intervention. DESIGN: We screened articles found through PubMed/Medline, African Journal OnLine, Science Direct, Google/Google Scholar, and ResearchGate. We included patient-reported surveys on the reasons linked to delayed presentation under 6 previously identified themes: symptom misinterpretation, fear, preference for alternative care, social influence, hospital-related factors, and access factors. The meta-analytical procedure in MetaXL used the quality-effect model. RESULTS: Twelve of the 236 identified articles were eligible for this review. The overall summary estimate of late presentation (> 90 days) was 54% (95% CI, 23 to 85) and was worst in the eastern and central regions. Symptom misinterpretation was the most common theme (50%; 95% CI, 21 to 56), followed by fear (17%; 95% CI, 3 to 27), hospital-related theme (11%; 95% CI, 1 to 21), preference for alternative care (10%; 95% CI, 0 to 21), social influence (7%; 95% CI, 0 to 14), and access-related theme (6%; 95% CI, 0 to 13). The most common factor underlying symptom misinterpretation was mischaracterizing the breast lesion as benign (60%; 95% CI, 4 to 100) which surpassed lack of awareness in the last decade. Misdiagnosis and failure to refer were the dominant hospital-related factors. CONCLUSION: Modifiable factors such as mischaracterizing malignant masses as benign, fear, misdiagnosis, and failure to refer were the prevalent factors contributing to delays throughout Africa. These factors are promising targets for intervention.

RESUMO

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.

RESUMO

Primary melanoma of the small bowel is a rare clinical entity with a paucity of published reports in literature. Most cases of gastrointestinal melanomas are metastatic lesions arising from skin or ocular origins. This is a case report of a 63 year old female with adult intussusception with jejunal melanoma as the lead point. The index patient had a long history of abdominal pain associated with significant weight loss and presented with features of intestinal obstruction. The possibility of a regressed or unidentified extra-intestinal site cannot be absolutely excluded as the patient did not have a PET scan. Due to the vague nature of clinical symptoms and signs, the diagnosis of small bowel melanoma is difficult, especially in patients with no obvious cutaneous pathology. A high index of suspicion for melanoma as a malignant lead point for adult intussusception should always be entertained.

RESUMO

BACKGROUND: Reports are scanty on the impact of long primary care interval in breast cancer. Exploratory reports in Nigeria and other low-middle-income countries suggest detrimental impact. The primary aim was to describe the impact of long primary care interval on breast cancer progression, and the secondary aim was to describe the factors perceived by patients as the reason(s) for long intervals. METHOD: Questionnaire-based survey was used in 9 Nigerian tertiary institutions between May 2017 and July 2018. The study hypothesis was that the majority of patients stayed >30 days, and the majority experienced stage migration in primary care interval. Assessment of the impact of the length of interval on tumor stage was done by survival analysis technique, and clustering analysis was used to find subgroups of the patient journey. RESULTS: A total of 237 patients presented to primary care personnel with tumor ≤5cm (mean 3.4±1.2cm). A total of 151 (69.3%, 95% CI 62.0-75.0) stayed >30 days in primary care interval. Risk of stage migration in primary care interval was 49.3% (95% CI 42.5%-56.3%). The most common reasons for long intervals were symptom misinformation and misdiagnosis. Clustering analysis showed 4 clusters of patients' experience and journey: long interval due to distance, long interval due to misinformation, long interval due to deliberate delaying, and not short interval-prepared for treatment. CONCLUSION: The majority of patients stayed longer than 30 days in primary care interval. Long primary care interval was associated with a higher risk of stage migration, and more patients reported misinformation and misdiagnosis as reasons for a long interval.

RESUMO

BACKGROUND: Airway management problems may arise when intubating patients with goitre scheduled for thyroidectomy. Goitres are not uncommon in sub-Saharan Africa, thyroidectomy being the main treatment. The aim of this study was to determine incidences of difficult intubation (DI), failed intubation (FI) and predictors of DI using a modified intubation difficulty score (IDS). METHODS: One hundred and twenty-five consenting patients with goitre scheduled for thyroidectomy were recruited. Goitre-related factors (GRF) of duration of illness, diagnosis, neck circumference, tracheal deviation and narrowing and retrosternal extension were recorded as well as Mallampati classification and BMI. At intubation, modified IDS was determined for each patient. Patients with modified IDS ≤ 5 were categorized as easy intubation group (E), and those with modified IDS >5 were categorized as difficult intubation group (D). The GRF of all patients in group D were compared with matched patients in group E. RESULTS: Incidence of DI was 13.6% with 2 (1.6%) cases of failed intubation. Comparing groups D and E, duration of illness was 4.28 ± 3.78 years in group D versus 7.44 ± 7.63 years group E, p = 0.1353. Neck circumference was 41.42 ±5.30 cm in group D versus 37.43±2.68 cm in group E, p = 0.0200. Tracheal deviation, narrowing and retrosternal extension, and surgical diagnosis were not significantly different among both groups. CONCLUSION: Incidence of DI was 13.6% and that of FI was 1.6%. Neck circumference was found to be a predictor of difficult intubation in goitre patients scheduled for thyroidectomy using the modified IDS.

RESUMO

BACKGROUND: Colorectal cancer (CRC) rates in low-resource countries, which typically lack CRC screening programs, are rising. This study determined whether a risk model for patients with rectal bleeding could identify patients with curable CRC. METHODS: This prospective, cross-sectional study evaluated a model constructed from data from 1 hospital and validated at 2 other hospitals. The primary endpoint was the ability of the model to predict CRC, as diagnosed by colonoscopy, from clinical characteristics. The secondary endpoint was to determine the percentage of patients who had CRC. RESULTS: Consecutive patients who were 45 years old or older and had self-reported rectal bleeding for more than 1 week were evaluated. From January 2014 to July 2016, 362 patients answered a questionnaire and underwent colonoscopy. In the validation cohort, 56% of patients with rectal bleeding, weight loss, and changes in bowel habits had CRC, whereas 2% of patients with bleeding alone did. Overall, 18.2% of the patients had CRC, and 8.6% had adenomas. The proportion of CRC patients with potentially curable stage II or III disease was 74%, whereas the historical rate was 36%. The combination of rectal bleeding with both symptoms significantly predicted CRC in the validation set (odds ratio, 12.8; 95% confidence interval, 4.6-35.4; P < .001). CONCLUSIONS: In low-resource settings, patients with rectal bleeding, weight loss, and changes in bowel habits should be classified as high risk for CRC. Patients with a high risk score should be prioritized for colonoscopy to increase the number of patients diagnosed with potentially curable CRC.

RESUMO

Purpose Colorectal cancer (CRC) incidence rates are steadily increasing in Nigeria. Organized screening is still largely unused because of financial and logistical barriers; most CRCs are detected by symptoms. One symptom of CRC is rectal bleeding. This study sought to determine health-seeking behavior and barriers to care in patients with rectal bleeding in Nigeria. This study also surveyed physicians to determine major breakdowns in access to care. Methods The recruitment process for this study involved patients referred for colonoscopy because of rectal bleeding as well as response to a media advertisement for a free colonoscopy. Physicians were recruited at the African Research Group for Oncology meeting. Patient responses were scored on the basis of knowledge of rectal bleeding. The physician questionnaire was supporting information and mainly descriptive in nature. Results A total of 82 patients and 45 physicians participated in this study. Less than 40% of patients knew that rectal bleeding could be caused by cancer. Major barriers to care were resolution of the symptom (42%), no consideration of the bleeding as problematic (40%), and financial constraint (22%). Education was strongly correlated with knowledge of rectal bleeding and health-seeking behavior. Although physicians regularly saw patients with rectal bleeding, most of them provided a differential diagnosis of hemorrhoids and few referred patients for colonoscopy. Conclusion General awareness about the signs of colorectal cancer is lacking. This demonstrates the strong need for patient education programs about this issue. Physicians should also receive additional training on differentiation of a potential cancer diagnosis from something more benign, such as hemorrhoids.

RESUMO

PURPOSE: There is an increasing effort in the global public health community to strengthen research capacity in low- and middle-income countries, but there is no consensus on how best to approach such endeavors. Successful consortia that perform research on HIV/AIDS and other infectious diseases exist, but few papers have been published detailing the challenges faced and lessons learned in setting up and running a successful research consortium. METHODS: Members of the African Research Group for Oncology (ARGO) participated in generating lessons learned regarding the foundation and maintenance of a cancer research consortium in Nigeria. RESULTS: Drawing on our experience of founding ARGO, we describe steps and key factors needed to establish a successful collaborative consortium between researchers from both high- and low-income countries. In addition, we present challenges we encountered in building our consortium, and how we managed those challenges. Although our research group is focused primarily on cancer, many of our lessons learned can be applied more widely in biomedical or public health research in low-income countries. CONCLUSIONS: As the need for cancer care in LMICs continues to grow, the ability to create sustainable, innovative, collaborative research groups will become vital. Assessing the successes and failures that occur in creating and sustaining research consortia in LMICs is important for expansion of research and training capacity in LMICs.

RESUMO

INTRODUCTION: Breast cancer is the most common cancer in females. It is the most common cause of cancer-related death among women with fatality rates highest in low-income countries. The aim of this study is to determine the socio-demographic and clinical profile of patients with immunohistochemically confirmed breast cancer in a Nigerian tertiary health institution. METHODS: Patients with immunohistochemically confirmed breast cancer were reviewed. The information retrieved was entered into a proforma designed for the purpose of the study. Data was analysed using SPSS version 18.0. RESULTS: The peak incidence of age at presentation was in the 5th decade. More than 50% of the patients were premenopausal and perimenopausal at presentation. Only 11% of the patients presented with breast lumps less than 2 cm in size. Women in the age group 50-59 years are more likely to present with larger breast lumps than women in other groups. More than 50% had clinically palpable lymph node at presentation. Mastectomy (simple mastectomy and modified radical mastectomy) and adjuvant chemotherapy were the main form of treatment. Most of the cases were estrogen receptor negative with majority of them having basal-like subtype. CONCLUSION: Most of the patients in this study were not only young but presented with locally advanced disease. Population screening, adequate health education, improved accessibility and availability of heath care will go a long way to improve the outcome of these patients.
