Cancer Genetic Services in a Low- to Middle-Income Country: Cross-Sectional Survey Assessing Willingness to Undergo and Pay for Germline Genetic Testing.

PURPOSE: Cancer genetic testing (CGT), a pathway to personalized medicine, is also being embraced in Nigeria. However, little is known about the influence of demographics and perceptions on individuals' willingness to access and pay for CGT. This study assessed patients' willingness to undergo CGT in southwest Nigeria as a catalyst for sustainable Cancer Risk Management Program. METHODS: This was a cross-sectional study using semistructured questionnaire to interview 362 patients with cancer and 10 referred first-degree relatives between July 2018 and February 2020. Participants from three Nigerian teaching hospitals-University College Hospital, Ibadan, Lagos State University Teaching Hospital, Lagos, and Lagos University Teaching Hospital, Lagos, received genetic counseling and had subsequent CGT. Primary outcomes were willingness to undergo CGT in determining cancer risk and the willingness to pay for it. Ethical approval was from appropriate ethics committees of participating hospitals. Data were analyzed with SPSS version 22. Univariate comparison of categorical variables was performed by χ2 test, multivariate analysis by logistic regression. RESULTS: The participants from University College Hospital (56.2%), Lagos State University Teaching Hospital (26.3%), and Lagos University Teaching Hospital (17.5%) were mostly female (98.4%). Mean age was 48.8 years ± 11.79. Three hundred twenty-two (86.6%) patients and first-degree relatives were willing to take the test, of whom 231 (71.1%) were willing to pay for it. more than half (53.6%) of the participants were willing to pay between N10,000 and N30,000, which is less than $100 US dollars. Sociodemographic variables and willingness to test showed no association (P > .05). Education and ethnicity were found to be associated with their willingness to pay for CGT (P ≤ .05). CONCLUSION: Learning clinically relevant details toward cancer prevention informs health-related decisions in patients and relatives, a motivator for willingness to pay for genetic testing in low- and middle-income countries. Increased awareness may influence outcomes of cancer risk management.

Feasibility of genetic testing for cancer risk assessment programme in Nigeria.

BACKGROUND: A high frequency of BRCA mutations has been established in Nigerian breast cancer (BC) patients. Recently, patients' and first-degree relatives' interest have been raised on cancer genetic risk assessment through our awareness activities in Nigeria. This led to the emergence of nurse-led cancer genetic counselling (CGC) and testing aimed at providing standard-of-care for individuals at increased risk of hereditary breast and ovarian cancers. METHODS: In June 2018, CGC and testing of patients with BC and ovarian cancer (OC) commenced in collaboration with Color Genomics Inc. for a 30-panel gene testing. Previously trained nurses in CGC at the University College Hospital, Ibadan offered genetic counselling (GC) to willing patients with BC and gynaecological cancer in four out-patient oncology clinics and departments for the pilot study. Consultation consisted of CGC, patient's history, pedigree and sample collection for genetic testing (GT). RESULTS: Forty-seven patients - 40 with BC, five with OC and two with endometrial cancer received GC, and all chose to undergo GT. The average age at testing was 48.2 ± 12.1 years. Eight women reported a known family cancer history and there were more perceived benefits than barriers to GT with the patients experiencing the desire for none of their relative to have cancer. Results revealed no mutations in 27 (57.4%), 16 (4.0%) variants of unknown significance and 4 (8.5%) pathogenic mutations. CONCLUSION: Personalised cancer care utilises GC and testing for cancer risk assessment towards prevention and early detection in high risk women. The study indicates the necessity of expanded cancer genetic services for integration into patient care and cancer prevention.
