Innovative Use of mHealth and Clinical Technology for Oncology Clinical Trials in Africa

Utilization of clinical technology and mobile health (mHealth) is expanding globally. It is important to reflect on how their usage and application could translate in low- and middle-income country (LMIC) settings. With the exponential growth and advancements of mobile and wireless technologies, LMICs are prime to adapt such technologies to potentially democratize and create solutions to health-related challenges. The role of these technologies in oncology clinical trials continues to expand. The lure of mHealth promises disruptive technology that may change the way clinical trials are designed and conducted in many settings. Its applicability in the African context is currently under consideration. Although potentially of expanding benefit, the role of these technologies requires careful and nuanced evaluation of the context in which they might be applied to harness their full potential, while mitigating possible harms or preventing further deepening of disparities within populations. Moreover, technology and digital innovations are no substitute for poor referral pathways and dysfunctional health systems and can only complement or enhance definite strategies aimed at strengthening these health system

Cancer pain control in a Nigerian oncology clinic: treating the disease and not the patient

Introduction: inadequate pain control negatively impacts the quality of life of patients with cancer while potentially affecting the outcome. Proper pain evaluation and management are therefore considered an important treatment goal. This study assessed the prevalence of pain, the prescribing patterns, and the efficacy of pain control measures in cancer patients at the Radiation Oncology Unit of the Lagos University Teaching Hospital, Lagos. Methods: this was a longitudinal study design recruiting adults attending outpatient clinics. Participants were assessed at initial contact and again following six weeks using the Universal Pain Assessment Tool developed by the UCLA Department of Anaesthesiology. Results: among the patients reviewed, 34.0% (118 of 347) were at the clinic, referred for initial assessment following primary diagnosis. All respondents had solid tumours; the most common was breast cancer. The prevalence of pain at initial assessment was 85.9% (298 of 347), with over half of respondents, 74.5% (222 of 347) characterising their pain as moderate to severe. Over a quarter, 28.9% (100 of 347) of patients were not asked about their pain by attending physicians, and none of the patients had a pain assessment tool used during evaluation. In 14.4% (43 of 298) of patients, no intervention was received despite the presence of pain. At six weeks review, 31.5% (94 of 298) of patients had obtained no pain relief despite instituted measures. Conclusion: under-treatment of cancer pain remains a significant weak link in cancer care in LMICs like Nigeria, with a significant contributor being physician under-evaluation and under-treatment of pain. To ensure pain eradication, the treatment process must begin with a thorough evaluation of the patient's pain, an explicit pain control goal and regular reevaluation

Prognostic performance of pretreatment systemic immune-inflammation index in women with epithelial ovarian cancer

Purpose: This study investigated the prognostic performance of the systemic immune-inflammation index (SII) in patients with epithelial ovarian cancer (EOC) in Lagos, Nigeria. Methods: We performed a secondary analysis of the data of 91 women who had treatment for EOC between 2009 and 2018. The associations between pretreatment SII and survivals were tested. Results: Pretreatment SII more than 610.2 was a significant independent predictor of reduced progression-free survival (HR = 2.68; 95% CI, 1.17 to 6.09) while SII greater than 649.0 was a significant independent predictor of reduced 3-year overall survival (HR = 2.01; 95% CI, 1.01 to 3.99). Conclusion: These findings suggest that high SII may be a potential prognostic indicator and useful marker for more intensive surveillance and design of personalized treatment in patients with EOC

Utilization of Cancer Information System for Breast Cancer Control in Lagos, Nigeria

Introduction: there is a substantial increase in the incidence of breast cancer in Nigeria usually with the late stage presentations and subsequent poor rates of survival attributed mainly to a low level of cancer awareness and ignorance amongst patients. Cancer information system (CIS) is now assuming an emerging role in this respect. Methods: this was a descriptive study carried out over a one year period using a health communications program comprising of 3 breast help lines. An initial period of public awareness was carried out over a 3 months period after which members of the public were encouraged to call the help lines. Breast cancer information was provided and the socio-demographic characteristics and other relevant data of the callers were recorded by the information specialists.  Results:  a total of 294 people were reached during the study period. Majority of the callers (82%) sought information for themselves while the remaining 18% called on behalf of a loved one or friend. Majority [248 (84.3%)] of callers had no breast abnormality, 38 (13%) called to report breast abnormalities and required information on what to do and 8 (2.7%) were breast cancer patients who required information on how to live and cope as breast cancer survivors. Conclusion: the rapid growth of mobile phone use in the Nigeria has presented a unique opportunity and promise to improve cancer care. There is evidence to suggest that mHealth can be used to deliver increased health care services to the increasing population of cancer patients in Nigeria.The Pan African Medical Journal 2016;2

Collaborative Molecular Epidemiology Study of Metabolic Dysregulation, DNA Methylation, and Breast Cancer Risk Among Nigerian Women: MEND Study Objectives and Design

PURPOSE To elucidate the role of metabolic dysregulation and associated DNA methylation changes on breast cancer risk and aggressive subtypes among Nigerian women. We describe the design and methods of a collaborative molecular epidemiology study of breast cancer in Nigerian hospitals. METHODS The Mechanisms for Novel and Established Risk Factors for Breast Cancer in Women of Nigerian Descent (MEND) study was designed as a matched case-control study of 350 patients, age 18 to 75 years, with newly diagnosed, treatment-naive breast cancer and 350 age-matched healthy controls from surrounding geographic areas. Patients with breast cancer seen for initial diagnosis at four large tertiary hospitals in southwest Nigeria and one affiliated private hospital were recruited. Healthy female controls were selected from a cohort of 4,000 healthy women recruited as part of the Human Heredity and Health (H3) in Africa Chronic Kidney Disease Case-Control Study in Nigeria. Tumor and adjacent normal tissue, and blood and saliva samples were collected for molecular and epigenetic assays. RESULTS Although recruitment is ongoing, a total of 416 patients have been recruited to date, with tumor and blood samples obtained from at least 310 patients. Data on age-matched (6 months) controls have also been obtained and harmonized. Lipid assays for 350 pathologically verified cases and 350 age-matched controls is underway, and pathologic characterization of tumors (including immunohistochemistry for subtyping) is ongoing. Data on DNA methylation for tumors and adjacent normal tissue are expected by the end of the study period. CONCLUSION The MEND study will provide a unique, high-quality source of data to evaluate the contribution of metabolic dysregulation such as obesity, diabetes, hypertension, and metabolic syndrome to the biology of breast cancer among Nigerian women and foster collaborative studies relevant for women of African descent globally.

Impact of Mobile Technologies on Cervical Cancer Screening Practices in Lagos, Nigeria (mHealth-Cervix): A Randomized Controlled Trial

Purpose We assessed the impact of mHealth on Pap test screening uptake and also determined the factors that affect screening uptake among women in Lagos, Nigeria. Materials and Methods A randomized controlled trial was carried out among women in two tertiary health institutions in Lagos, Nigeria, between July 2020 and March 2021. Participants were randomly assigned to either a text message (mHealth) intervention or usual care arm. The main study outcome was the uptake of Pap smear testing within 6 months of enrollment in the study. We tested the associations between two groups of continuous variables using the unpooled independent-sample t-test (normal distribution) and that of two groups of categorical variables with the chi-square (χ2) test. Using a multinomial logistic regression model, we adjusted for relevant sociodemographic and clinical predictors of uptake of Pap smear screening. Statistical significance was defined as P < .05. Results There was a significantly higher rate of uptake of Pap smear screening among women in the mHealth arm compared with those in the usual care arm (51.0% v 35.7%, P = .031). Following adjustment in the final multivariate model, level of income (odds ratio [OR] = 5.13, 95% CI, 1.55 to 16.95), awareness of Pap smear (OR = 16.26; 95% CI, 2.49 to 76.64), General Outpatient clinic attendance, and introduction of mHealth intervention during follow-up (OR = 4.36; 95% CI, 1.44 to 13.22) were the independent predictors of Pap smear uptake. Conclusion The use of mHealth technologies intervention via short-text message services is a feasible solution for cervical cancer prevention in low- and middle-income countries, and thus, the widespread use of mHealth services by health care providers and policymakers could contribute to the implementation of cervical cancer prevention services in Nigeria and in the settings of other low- and middle-income countries

Association of Body Composition with Odds of Breast Cancer by Molecular Subtype: Analysis of the Mechanisms for Established and Novel Risk Factors for Breast Cancer in Nigerian Women (MEND) Study

BACKGROUND: The association between obesity and breast cancer (BC) has been extensively studied among US, European and Asian study populations, with often conflicting evidence. However, despite the increasing prevalence of obesity and associated conditions in Africa, the continent with the highest age-standardized BC mortality rate globally, few studies have evaluated this association, and none has examined in relation to molecular subtypes among African women. The current analysis examines the association between body composition, defined by body mass index (BMI), height, and weight, and BC by molecular subtype among African women. METHODS: We estimated odds ratios (ORs) and 95% confidence intervals (95% CI) for the association between measures of body composition and BC and molecular subtypes among 419 histologically confirmed cases of BC and 286 healthy controls from the Mechanisms for Established and Novel Risk Factors for Breast Cancer in Women of Nigerian Descent (MEND) case-control study. RESULTS: Higher BMI (aOR: 0.79; 95% CI: 0.67, 0.95) and weight (aOR: 0.83; 95% CI: 0.69, 0.98) were associated with reduced odds of BC in adjusted models, while height was associated with non-statistically significant increased odds of BC (aOR: 1.07, 95% CI: 0.90, 1.28). In pre/peri-menopausal, but not post-menopausal women, both higher BMI and weight were significantly associated with reduced odds of BC. Further, higher BMI was associated with reduced odds of Luminal A, Luminal B, and HER2-enriched BC among pre/peri-menopausal women, and reduced odds of triple-negative BC among post-menopausal women. CONCLUSIONS: Higher BMI and weight were associated with reduced odds of BC overall and by molecular subtype among West African women. Larger studies of women of African descent are needed to definitively characterize these associations and inform cancer prevention strategies

A rare case of ovarian dysgerminoma in a 6‑year old child in Lagos: A case report

Dysgerminoma is the most common malignant germ cell tumor in children and adolescents. Most cases occur in the 2nd and 3rd decades of life, but 10% of cases occur in the 1st decade of life. The rarity of this malignancy in prepubertal children and the recognized controversies in its management prompted this case report. The case of a 6‑year‑old girl who had laparotomy and unilateral adnexectomy with subsequent histological diagnosis of an ovarian dysgerminoma was presented. Prognosis depends on the stage of the tumor at presentation, and conservative surgery should be the aim during the initial treatment. Adoption of multidisciplinary management within an oncology board with joint decision on the need for adjuvant chemotherapy for early stage diseases will confer good prognosis.Keywords: Germ cell tumor; malignant; management; multidisciplinar
