Abstract 57: Experiences and Beliefs Regarding Shared Decision-Making About Treatment of Incurable Cancer in Tanzania

Abstract Purpose: Treatment decision-making in the setting of advanced cancer is often complex and culturally embedded. Potential benefits of treatment must be weighed against toxicities, economic burden, and social consequences. The standard of shared decision-making (SDM) between doctor and patient, rooted in the Western principle of patient autonomy, may not be readily transferable to other cultural and socioeconomic contexts, where different values and considerations may take precedence. This study aims to characterize the decision-making experiences and beliefs of stakeholders at Ocean Road Cancer Institute (ORCI) in Tanzania in order to inform communication guidelines and improvement strategies. Methods: We conducted semi-structured interviews with a purposive sample of oncologists and nurses (n=13) and patients with advanced cancer (n=11) at ORCI. A diagram depicting paternalistic, informed, and shared approaches to decision-making was referenced during interviews. Interviews were recorded, transcribed verbatim, translated to English, coded using MAXQDA software, and analyzed using framework thematic analysis. Results: Patients and providers reported heterogeneous decision-making experiences and preferences, with a trend toward greater patient engagement in recent years. Providers believed SDM is especially important when treatment goals are palliative and when out-of-pocket costs are significant, but favored paternalistic decision-making in the context of curative treatment and lower patient health literacy. Patients generally placed greater importance on providers' communication style and the quality of clinical care than engagement in SDM. Several participants perceived SDM to increase patient adherence to treatment. Barriers and facilitators of SDM were identified at the patient, provider, and healthcare system levels. Community misperceptions about cancer treatment was commonly cited as a barrier. Practical suggestions included communication skills training for providers, implementation of a clinical tool for decision-making, and increased patient and public education about cancer treatment. Conclusion: Understanding the nuanced views regarding SDM is important for development of culturally informed communication guidelines, tools, and training.

Concordance in HPV Detection Between Self-Collected and Health Provider-Collected Cervicovaginal Samples Using careHPV in Tanzanian Women.

PURPOSECervical cancer screening is one of the strategies to prevent the disease among women at risk. Human papillomavirus (HPV) DNA testing is increasingly used as the cervical cancer screening method because of its high sensitivity. Self-collection of cervical specimens has the potential to improve participation. However, there is only limited information on comparison between self-collected and provider-collected samples with regard to detection of high-risk HPV using the careHPV method. The study aimed to compare HPV detection by careHPV in self-collected and provider-collected cervical samples and to assess the acceptability of self-collection techniques.MATERIAL AND METHODSWomen attending cervical cancer screening clinics at Ocean Road Cancer Institute, Kilimanjaro Christian Medical Centre or Mawenzi Hospital in Tanzania were included in the study. They underwent a face-to-face interview, HIV testing, and collected a self-sample using Evalyn Brush. Subsequently, they had a cervical sample taken by a health provider. Both samples were tested for high-risk HPV DNA using careHPV.RESULTSOverall, 464 women participated in the study. The high-risk HPV prevalence was 19.0% (95% CI, 15.6 to 22.9) in the health provider samples, but lower (13.8%; 95% CI, 10.9 to 17.3) in the self-collected samples. There was a good overall agreement 90.5% (95% CI, 87.5 to 93.0) and concordance (κ = 0.66; 95% CI, 0.56 to 0.75) between the two sets of samples. Sensitivity and specificity were 61.4% (95% CI, 50.4 to 71.6) and 97.3% (95% CI, 95.2 to 98.7), respectively, varying with age. Most women preferred self-collection (79.8%).CONCLUSIONOverall, self-sampling seems to be a reliable alternative to health-provider collection and is acceptable to the majority of women. However, instructions on proper procedures for sample collection to the women are important.

Views from Multidisciplinary Oncology Clinicians on Strengthening Cancer Care Delivery Systems in Tanzania.

BackgroundIn response to the increasing burden of cancer in Tanzania, the Ministry of Health, Community Development, Gender, Elderly and Children launched National Cancer Treatment Guidelines (TNCTG) in February 2020. The guidelines aimed to improve and standardize oncology care in the country. At Ocean Road Cancer Institute (ORCI), we developed a theory‐informed implementation strategy to promote guideline‐concordant care. As part of the situation analysis for implementation strategy development, we conducted focus group discussions to evaluate clinical systems and contextual factors that influence guideline‐based practice prior to the launch of the TNCTG.Materials and MethodsIn June 2019, three focus group discussions were conducted with a total of 21 oncology clinicians at ORCI, stratified by profession. A discussion guide was used to stimulate dialogue about facilitators and barriers to delivery of guideline‐concordant care. Discussions were audio recorded, transcribed, translated, and analyzed using thematic framework analysis.ResultsParticipants identified factors both within the inner context of ORCI clinical systems and outside of ORCI. Themes within the clinical systems included capacity and infrastructure, information technology, communication, efficiency, and quality of services provided. Contextual factors external to ORCI included interinstitutional coordination, oncology capacity in peripheral hospitals, public awareness and beliefs, and financial barriers. Participants provided pragmatic suggestions for strengthening cancer care delivery in Tanzania.ConclusionOur results highlight several barriers and facilitators within and outside of the clinical systems at ORCI that may affect uptake of the TNCTG. Our findings were used to inform a broader guideline implementation strategy, in an effort to improve uptake of the TNCTGs at ORCI.Implications for PracticeThis study provides an assessment of cancer care delivery systems in a low resource setting from the unique perspectives of local multidisciplinary oncology clinicians. Situational analysis of contextual factors that are likely to influence guideline implementation outcomes is the first step of developing an implementation strategy for cancer treatment guidelines. Many of the barriers identified in this study represent actionable targets that will inform the next phases of our implementation strategy for guideline‐concordant cancer care in Tanzania and comparable settings.

Developing Research Education Groups in African Cancer Centers: The Experience in Tanzania.

Research productivity and outcomes of junior researchers are usually correlated with the degree and quality of mentorship they receive. A bottom-up approach was followed to develop a research group at the Ocean Road Cancer Institute (ORCI), the major cancer center in Tanzania, to build upon the existing clinical and research resources and institutional global collaborations. The ORCI is a clinical center focused on radio- and chemo-therapy treatment of cancer patients from all over Tanzania. In addition, ORCI has a long-standing early detection program for educating women and screening them for cervical cancer. The ORCI physicians have been exposed to cancer research for the past 20years through non-degree and degree training in the USA and Europe. In addition, US and European groups have been conducting collaborative research and training of oncologists and graduate students at ORCI. The exposure to research through the above-listed venues motivated the clinicians at ORCI to develop their own Research Club (RC) to learn about research methods, seek independent funding, and outline a research agenda for cancer research in Tanzania. However, it seems that mentorship is needed to help the RC members apply the lessons learned from didactic teaching. Mentorship is also needed to enable the RC members to utilize the enormous clinical and epidemiologic data generated by the institutional programs for prevention, treatment, and follow up of patients. This manuscript describes the inception of the program and its achievements, limitations, and suggested opportunities for improvement as a possible model for other LMICs.

Field Research Experience of Medical Students: Learning and Translation from Global to Underserved US Settings.

While most medical schools in the USA provide opportunities for global health experiences, global health education is not included consistently or emphasized adequately in many medical school curricula. The City University of New York Medical School (CSOM) has a mission to educate and train students who are traditionally underrepresented in medicine to practice primary care in medically underserved communities in New York. This manuscript documents the experience of the CSOM in expanding global health education by introducing a new global health cancer training program, partnering with clinicians at the Ocean Road Cancer Institute (ORCI) in Tanzania. This manuscript illustrates the following points: (1) the CSOM curriculum that focuses on community health and social medicine; (2) the process by which students learn by developing research proposals for global cancer; (3) the field research experience and lessons learned; (4) learning about cancer and medicine in a developing country; and (5) lessons learned for translation from global to domestic underserved populations. We also suggest a checklist for future students interested in pursuing global cancer education and research, and recommendations for maximizing learning and career development of students interested in global cancer research and its application to underserved populations in the USA.

Survival in Cervical Cancer and Its Predictors at Ocean Road Cancer Institute From January to December 2012.

PURPOSEIn Tanzania, cancer of cervix is the most commonly diagnosed cancer and is the leading cause of cancer-related deaths. There are very little data about survival of patients with cervical cancer after treatment in Tanzania. The aims of this study were to determine 5-year overall survival (OS) rate and its predictors among patients with cervical cancer treated at Ocean Road Cancer Institute (ORCI) from January to December 2012.MATERIALS AND METHODSThis was retrospective study done at ORCI by reviewing medical charts of 202 patients with cervical cancer treated at ORCI from January to December 2012. A structured questionnaire was used to extract information about characteristics of the respondents. Survival curves were estimated by using Kaplan-Meir analysis and were compared by using log-rank test.RESULTSThe 5-year OS rate was 26%. The mean and median survival times were 33.9 and 19 months, respectively. Factors that were positively associated with 5-year OS rate include the hemoglobin level more than 9 g/dL at presentation, early International Federation of Gynecology and Obstetrics stage at presentation, high dose of radiotherapy, and use of concurrent chemoradiotherapy. Histology type and HIV status were not associated with survival.CONCLUSIONThe 5-year overall survival rate was 26%. Predictors of OS were hemoglobin level, stage at presentation, radiotherapy dose, and the use of concurrent chemoradiotherapy.

Late Presentation, Advanced Disease and Severe Acute Malnutrition are Common Among Children with Cancer in Tanzania

Background Majority of children with cancer live in low and middle-income countries (LMIC) where survival is disproportionately low compared to high-income countries (HIC). Among the challenges of managing childhood cancers in LMIC is late presentation, advanced disease, and the prevalence of severe malnutrition. Advanced disease and severe acute malnutrition are associated with poor treatment outcomes. Methodology This was a descriptive study conducted in Tanzania at Ocean Road Cancer Institute (ORCI) in 2010. Children and adolescents below 18 years were longitudinally enrolled in the study. Pathological diagnosis was made by examination of tissue biopsies, fine needle aspiration (FNAC) or bone marrow aspiration cytology (BMAC). Stage of disease at presentation was determined by physical examination and radiological investigations such as chest x-ray and ultrasonography. World Health Organization (WHO) anthropometric measurement chart was used to interpret measured Mid-upper arm circumference (MUAC) for age. Body mass index (BMI) is affected by tumour weight hence was not used to assess malnutrition in this study. Results One hundred and fifty-one (151) patients were enrolled in the study. The mean age at presentation was 5.8 years (range 3-17years), and 51.7% of participants were males. Three quarters (76.6%) of patients attended the first health facility within a month of onset of symptoms, but forty per cent (40%) of patients took six (6) months to reach ORCI for treatment. Eighty-six percent (86%) of patients presented with advanced disease (50.8% - locally advanced, 35.1% - metastatic disease). Metastatic disease was more frequent in patients with Neuroblastoma (NB) and Non Hodgikins Lymphoma (NHL) (66.6% each), Burkitt’s lymphoma (BL) (50%), Soft tissue sarcoma (STS) (40%) and Wilm’s tumour (WT) (35.3%). Severe wasting was seen in 12.6% of patients, and more prevalent among patients with BL (31.3%) and WT (25%). Conclusion Even though most patients sought health care early, they reached ORCI late with advanced disease (86%), and 12.6% had severe acute malnutrition. Keywords: Children, Cancer, Advanced Disease, Malnutrition.

The Profile of Childhood Malignancies in Dar es Salaam, Tanzania

Background Majority of children with cancer live in low- and middle-income countries. The data is scarce on the epidemiology of childhood cancer in these countries. In this study, we enrolled children and adolescents with cancer at the only cancer hospital in Tanzania and determined the epidemiology and HIV infection among this population. Methodology This was a descriptive hospital-based study conducted at Ocean Road Cancer Institute in Dar es salaam, Tanzania. Data were collected for eight months (May to December 2010). Participants were enrolled consecutively as they presented to the hospital. Demographic data, HIV status and clinical diagnosis were determined and recorded. Each patient was followed up until a final diagnosis was reached, and investigations for disease staging were completed. Results One hundred and fifty-one (151) patients were enrolled in the study. Mean age at presentation was 5.8 years (range 3-17years), and 51.7% of participants were males. Sixty-three per cent (63%) of patients had their diagnoses confirmed by histology or cytology. Retinoblastoma was the most common malignancy (29.1%) followed by Nephroblastoma (11.3%), Burkitt lymphoma (10.6%) and Acute Lymphoblastic Leukemias (10.6%). More than half (58.2%) of patients aged three years or younger had Retinoblastoma. Four patients (2.8%) had HIV infection; three of them with Kaposi’s sarcoma and one with Burkitt lymphoma. Conclusion Retinoblastoma was the most typical malignancy followed by Wilms tumour, Burkitt lymphoma and acute lymphoblastic leukaemia. The prevalence of HIV infection was very low among patients with the described malignancies. Key Words: Childhood Malignancies, Tanzania.

Molecular response to imatinib in patients with chronic myeloid leukemia in Tanzania

Imatinib is the mainstay of treatment of patients with chronic myeloid leukemia (CML) in Tanzania. Monitoring molecular response to therapy by real-time polymerase chain reaction at defined milestones is necessary for early detection of treatment failure. However, this assay is not routinely performed in Tanzania; therefore, the depth of molecular response among patients with CML is not known. A total of 158 patients with previously diagnosed CML who received imatinib treatment were recruited from January 2019 and followed up through October 2020 at Ocean Road Cancer Institute. Information was obtained at the time of diagnosis and follow-up. Blood samples were collected in EDTA tubes to measure the BCR/ABL ratio on the Gene Xpert system for molecular response determination. The median age of the 158 adult patients was 45 years (range, 18-86). By reference to established treatment milestones, only 37 (23.4%) achieved optimal molecular response. Signs of advanced-stage disease, in particular the need for red cell transfusions before diagnosis (adjusted odds ratio [AOR], 3.4; 95% CI, 1.32-9.17) and cytopenias (AOR, 2.26; 95% CI, 1.03-4.96) necessitating drug interruptions were statistically validated predictors of treatment failure on multivariate, multinomial logistic regression. Patient survival at the 22-month follow-up was lowest, with 78.6% (95% CI, 69.4-85.4) in the failure-to-respond category and highest in patients achieving optimal response 97.0% (95% CI, 80.9-99.6). In summary, the majority of patients with CML treated with imatinib in Tanzania do not obtain deep molecular response. This outcome can be attributed to late diagnosis, the development of cytopenias requiring multiple drug interruptions, and poor adherence to treatment.

Agreement between careHPV and hybrid capture 2 in detecting high-risk HPV in women in Tanzania.

Visual inspection of the cervix with acetic acid is used to control the burden of cervical cancer in low- and middle-income countries. This method has some limitations and HPV DNA testing may be an alternative, but it is expensive and requires a laboratory setup. Cheaper and faster HPV tests have been developed. This study describe the agreement between a fast HPV test (careHPV) and hybrid capture 2 (HC2) in detection of high-risk HPV among Tanzanian women. The study involved women attending routine cervical cancer screening at the Ocean Road Cancer Institute and Kilimanjaro Christian Medical Centre in Tanzania. The women were offered HIV testing. Two cervical samples were subsequently obtained; the first sample was processed at the clinics using careHPV and the second sample was transported to Denmark and Germany for cytology and HC2 analysis. Kappa statistic was calculated to assess the agreement between careHPV and HC2. The sensitivity, specificity and predictive values of careHPV were calculated using HC2 as reference. The analyses were done for the overall study population and stratified by testing site and HIV status. A total of 4080 women were enrolled, with 437 being excluded due to invalid information, lack of careHPV or HC2 results. Overall agreement between the tests was substantial with a kappa value of 0.69 (95% confidence interval [CI] 0.66-0.72). The sensitivity and specificity of careHPV was 90.7% (95% CI 89.6-91.8) and 84.2% (95% CI 81.2-86.8), respectively. The agreement was similar in the stratified analyses where the kappa values were 0.75 (95% CI 0.70-0.79) in women aged 25-34, 0.66 (95% CI 0.62-0.70) in women aged 35-60, 0.73 (95% CI 0.70-0.77) at the Ocean Road Cancer Institute, 0.64 (95% CI 0.60-0.69) at the Kilimanjaro Christian Medical Center, 0.73 (95% CI 0.68-0.79) in HIV-positive and 0.66 (95% CI 0.63-0.70) in HIV-negative women. The kappa value of 0.64 (95% CI 0.39-0.88) for cervical high-grade lesions indicates a substantial agreement between careHPV and HC2 in detecting HPV among women with cervical high-grade lesions. A substantial agreement was found between careHPV and HC2 in detecting HPV overall as well as detecting HPV among women with cervical high-grade lesions. However, given the limited resources available in low and middle-income countries, the HPV testing assay should be weighed against the cost-effectiveness of the test.

Downstaging of cervical cancer in Tanzania over a 16-year period.

Globally, the highest cervical cancer mortality rates are found in East Africa. Visual inspection with acetic acid (VIA)-based screening in resource-poor settings has been shown to decrease the proportion of women presenting with late-stage cervical cancer, a process known as clinical downstaging. The only cancer treatment center in Tanzania, Ocean Road Cancer Institute (ORCI) in Dar es Salaam, opened a VIA-based cervical cancer screening program in 2002. We reviewed 6,676 medical records of cervical cancer patients at the ORCI from 2002-2011 to 2014-2018 for stage at diagnosis and screening status, among other variables. We investigated whether clinical downstaging occurred in this period among women screened at the ORCI, when compared to unscreened women. Our results indicated that the proportion of women presenting with late-stage cervical cancer among women screened at the ORCI decreased by 27.7% over the 16-year period (χ2 = 16.99; p = 0.0002). Among unscreened women, a non-significant 13.2% decrease in late-stage disease was observed (χ2 = 1.74; p = 0.4179). Our results suggest clinical downstaging occurred among women screened at the ORCI over the 16-year period, and this difference may be attributed to the screening program as the same decrease in stage was not observed among unscreened women during the same time period. At present, less than one percent of Tanzanian women receive yearly cervical cancer screenings. Access to screening through expansion of the ORCI screening clinic and the creation of more clinics should be prioritized.

Factors influencing truth-telling by healthcare providers to terminally ill cancer patients at Ocean Road Cancer Institute in Dar-es-Salaam, Tanzania

Background: Widely accepted international clinical ethics standards and Tanzania’s national cancer treatments guidelines mandate that healthcare providers give patients the information they want or need in an understandable way. However, adherence to these standards is low particularly in developing countries. In Tanzania, little is known regarding the views and practice of disclosure of diagnosis and prognosis to cancer patients. Objective: In this study, we aimed at examining the factors influencing truth-telling by healthcare providers to terminally ill cancer patients at Ocean Road Cancer Institute (ORCI) in Dar-es-Salaam, Tanzania. Methods: We conducted semi-structured interviews with a purposive sample of healthcare providers (n=13) and terminally ill cancer patients (n=8) in English and Swahili. The interviews were recorded, transcribed verbatim, and translated to English. Results: Study findings show unsatisfactory experience of truth-telling according to international clinical standards. Many healthcare providers emphasized many barriers including: limited communication skills, limited time, a high volume of patients and lack of privacy for communication. Patients’ preferences and readiness to information as well as family collusion were identified as barriers, whereas communalism was identified as facilitator to truth-telling. Conclusion: We identified several barriers and facilitators of truth-telling that may be targeted in order to promote high-quality communication at ORCI. Our results support advocacy for improvements like: training for clinical communication skills and information sharing, space designated to enhance privacy, deliberate efforts to employ enough providers to care for the increasing volume of patients, and need of counselling session with patients and family members prior to clinical information disclosure

Factors related to completion of referral among women with suspected cervical cancer and dysplasia in Tanzania.

To investigate completion of referral among women with suspected cervical cancer in Tanzania. Retrospective cohort study of 196 women referred from two healthcare clinics to Ocean Road Cancer Institute, Dar es Salaam, between March 2016 and June 2018. Women with precancerous lesions or suspected cancer were interviewed about their knowledge and perception of cervical cancer and referred for follow-up. Most participants were unable to name symptoms (55.1%), prevention methods (88.3%), or treatments (59.0%), although 79.1% rated the disease as severe. Women who came for routine early detection were less likely to complete referral than those who did not (odds ratio [OR], 0.18; 95% confidence interval [CI], 0.05-0.70). Women who knew someone who died from cervical cancer were 5.40 times more likely to complete referral than those who did not. Knowing someone with cervical cancer was a predictor of referral completion in three multivariate models: OR, 5.62 (95% CI, 2.20-14.38); 4.34 (1.64-11.47); and 4.61 (1.72-12.36). Having severe symptoms was a predictor of non-completion in two models: 0.30 (0.12-0.75) and 0.35 (0.14-0.87). Patient-directed interventions should include education involving survivors of cancer and dysplasia, whereas system-directed interventions should utilize reminders to increase referral completion.

Quantifying the under-estimation of cervical Cancer in remote regions of Tanzania

BackgroundCervical cancer is the most common cancer among women in Sub-Saharan countries, including Tanzania. While early detection and diagnosis are available in some parts of this large country, radiotherapy has been only available at the Ocean Road Cancer Institute (ORCI), in the capital city of Dar es Salaam and is just starting in a few regions.MethodsThe objective of this study was to compare the observed incidence of cervical cancer for the two remote regions of Mwanza in western Tanzania and Mbeya in southern Tanzania, based on their patients treated at the ORCI from 2011 to 2014. Results: The number patients referred and treated at ORCI were (120 from Mwanza, and 171 from Mbeya, representing 24.6 and 32.8% of the patients histopathologically confirmed in the two sites, respectively. The results showed significant underestimation of cervical cancer in the two regions. The vast majority of patients who were histopathologically-confirmed in their local regions (73.92% from Mwanza and 65.1% from Mbeya), but did not receive the needed radiotherapy treatment at the ORCI. The estimated incidence for the two regions based on the number of patients treated at the ORCI were underestimated by 53.9% for Mwanza and 68.9% for Mbeya.ConclusionsLocal establishment of radiotherapy treatment facilities in remote regions in Tanzania and similar other low-income countries is essential for providing effective treatment and improving survival of diagnosed cervical cancer patients. Linkage between the records of local remote hospitals and the main cancer treatment center in the capital city can also help support the emerging the population-based cancer registry at ORCI.

Return on Investment of a Breast Cancer Screening Program in Tanzania: Opportunity for Patient and Public Education.

Breast cancer is the second incident and second cause of cancer mortality among women in Tanzania due to late-stage presentation. The screening clinic at the Ocean Road Cancer Institute (ORCI) can help detect cases early and reduce cost of treatment. We calculated the return on investment (ROI) of the ORCI breast screening clinic. Screening and treatment data of all newly diagnosed breast cancer patients seen at ORCI during 2016-2018 were abstracted from the medical records. Also, data on time, resources, and cost of screening and treatment were obtained. The cost of treating screened patients was compared with cost of treating unscreened patients, and differences in cost of treatment were compared with cost of operating the screening program. Of the 730 total patients, 58 were screened prior to treatment, and 672 were not. There was no significant difference between stage at diagnosis and treatments received by screened and unscreened patients (79.3% late- stage vs 72.2% late-stage diagnosis, respectively (p = .531), or cost of treatment between the two groups (cost, in Tanzanian Shillings, for screened (2,167,155.14 or $954.27) vs unscreened (1,918,592.28 or $844.52), (p = .355). There was also no significant difference in cost of treatment between the screened and unscreened groups and a slightly negative ROI (- 0.05%) from implementing the program. The breast screening clinic in Tanzania has not yet proven its cost-effectiveness in reducing stage with screening. The likelihood that patients have utilized the clinic for treatment rather than early detection is a possible reason for the lack of cost-effectiveness. Future studies should focus on educational initiatives to encourage screening at early disease stage. Public education should increase awareness about the clinic for early detection. The experience of this program is ideal for dissemination to other low-income countries that are initiating cancer early detection and cancer education programs.

Electrolytes supplementation can decrease the risk of nephrotoxicity in patients with solid tumors undergoing chemotherapy with cisplatin

BackgroundCisplatin is an important drug in the treatment of various Cancers. However, this drug causes nephrotoxicity that is linked to electrolyte derangement. The aim of this study was to evaluate the effect of electrolyte supplementation in reducing kidney injury in patients receiving cisplatin-based regimen.MethodsThis was non-randomized interventional study conducted at Ocean Road Cancer Institute (ORCI) among patients with confirmed solid tumors. Patients who received cisplatin-based chemotherapy at a dose of ≥50 mg with intravenous normal saline supplemented with Magnesium, Calcium and Potassium (triple electrolyte supplementation) were compared with those who received cisplatin-based chemotherapy with normal saline alone. The patients were followed up for 4 weeks and serum creatinine was measured at every visit. Nephrotoxicity was defined as serum creatinine elevation > 1.5 times that at baseline.ResultsA total of 99 patients were recruited, whereby 49 patients (49.5%) received electrolyte supplementation (treatment group) and 50 patients (51.5%) did not receive electrolyte supplementation (control group). The incidence risk of nephrotoxicity was 20.41% (n = 10) in the treatment group and 54% (n = 27) in the control group. Patients in the control group were 2.6 times more likely to experience nephrotoxicity as compared to treatment group [Relative Risks (RR); 2.6, 95%CI; 1.5–4.9, P < 0.0001]. The most common malignancy was cervical cancer, n = 43 (87.8%) in treatment group and n = 45 (90.0%) in the control group (P = 0.590). The Kaplan-Meier analysis and the log-rank test revealed that electrolytes supplementation was associated with extended survival with less nephrotoxicity incidences [P = 0.0004; Hazard ratio (HR) 0.3149; 95% CI 0.165 to 0.6011].ConclusionsElectrolytes supplementation decreases the risk of nephrotoxicity after chemotherapy with cisplatin. A randomized controlled trial with a larger sample size is recommended to evaluate the robustness of these findings.

Feasibility Study of a Smartphone Application for Detecting Skin Cancers in People With Albinism.

PURPOSEAlbinism affects some facets of the eye’s function and coloration, as well as hair and skin color. The prevalence of albinism is estimated to be one in 2,000-5,000 people in sub-Saharan Africa and one in 270 in Tanzania. People in Tanzania with albinism experience sociocultural and economic disparities. Because of stigma related to albinism, they present to hospitals with advanced disease, including skin cancers. Mobile health (mHealth) can help to bridge some of the gaps in detection and treatment of skin cancers affecting this population.METHODSWe assessed the feasibility of using a mobile application (app) for detection of skin cancers among people with albinism. The study was approved by the Ocean Road Cancer Institute institutional review board. Data, including pictures of the lesions, were collected using a mobile smartphone and submitted to expert reviewers. Expert reviewers’ diagnosis options were benign, malignant, or unevaluable.RESULTSA total of 77 lesions from different body locations of 69 participants were captured by the NgoziYangu mobile app. Sixty-two lesions (81%) were considered malignant via the app and referred for biopsy and histologic diagnosis. Of those referred, 55 lesions (89%) were biopsied, and 47 lesions (85%) were confirmed as skin malignancies, whereas eight (15%) were benign.CONCLUSIONWith an increasing Internet coverage in Africa, there is potential for smartphone apps to improve health care delivery channels. It is important that mobile apps like NgoziYangu be explored to reduce diagnostic delay and improve the accuracy of detection of skin cancer, especially in stigmatized groups.

Some Traits on the Outcome of the Treatment of Cervical Cancer in Tanzania: A Case Study of Ocean Road Cancer Institute (ORCI)

Background: In Tanzania, like in many other poor African countries, cervical cancer is a major problem facing women especially for those aged 30 years and above. This study aimed at constructing a statistical model to enable the prediction of the outcome of treatment for cervical cancer patients in Tanzania.&#x0D; Methods: Data were collected retrospectively from patient’s files with histological proven cervical cancer who were treated at Ocean Road Cancer Institute (ORCI) from year 2009 and followed up to year 2011. The factors considered are screening status, HIV status, disease stage, age, treatment type and the intent of the treatment. The study employed the Chi-square (χ2) test and the logistic regression model for its analysis.&#x0D; Results: The Chi-square (χ2) test result showed that there was a significant relationship between outcome of treatment and the patient screening status, HIV status, disease stage and intent of treatment at 5% level of significance. On the other hand, the logistic regression results found patient disease stage and intent of the treatment to be statistically significant at 95 percent. Logistic regression results also showed that patients who attended ORCI when their disease at a late stage had an odds ratio of 0.128 less likely to have favorable outcomes compared to those patients who attended ORCI when their disease stage was at early stages. The odds ratio for cervical cancer patients who received both treatment, radiotherapy, and chemotherapy was 2.643 more likely to have favorable outcomes&#x0D; Conclusion: More emphasis and campaigns should be made in order to encourage women all over the country to attend cancer centers for screening and treatment at early stages or even before any symptoms for cervical cancer and other types of cancers.

Experiences of women receiving high dose rate brachytherapy for cervical cancer at ocean road cancer institute Dar-es-salaam Tanzania

The objective of this study was to present a descriptive summary of the experiences of women treated with high dose rate brachytherapy for cervical cancer. A qualitative descriptive study design was used and 50 women who undergo high dose rate brachytherapy at Ocean Road Cancer Institute (ORCI) in Dar-es-salaam were selected. Qualitative interviewer administered questionnaire was used for data collection from cervical cancer patients treated between April 2019 to July 2019 for descriptive and thematic analysis of data. Qualitative interviewer administered questioning was done from which three themes arose: the patient perception, expectation and impressions, informational need, and psychological experiences. Many patients had good perception about brachytherapy although their first impression was bad. The study found the importance of provision of procedure information to patient which seems to improve their treatment experiences. The psychological experiences faced by patients before and during treatment included pain, distress, fear, humiliation and anxiety Pain was a major problem, as the preventative medication participants received had low efficiency in pain prevention hence did not protect them from experiencing pain. Opening and hanging their legs was a humiliating experience aggravated by the presence of doctors and nurses. Their belief that brachytherapy can cure their disease comforted them and gave them courage to endure the treatment, whilst caring staff comforted and supported them. In addition to individualized patient education, nurses should assess the level of pain women experience before, during and after receiving brachytherapy and advice the revision of pain management protocols.

Implementation of Tanzania’s National Cancer Treatment Guidelines: A Qualitative Approach to Clinical Systems

PURPOSE In response to the increasing burden of cancer in Tanzania, the Tanzanian Ministry of Health Community Development, Gender, Elderly, and Children plans to launch their first National Cancer Treatment Guidelines. These guidelines will provide an opportunity to improve and standardize care at Ocean Road Cancer Institute (ORCI), the national cancer center, where previous data suggest that patients do not consistently receive standard treatment. A theory-informed implementation strategy will be conducted to facilitate the routine use of guidelines among health care providers at ORCI. As part of the needs assessment for this effort, this study explored the barriers to and facilitators of guideline-concordant care at ORCI. METHODS We conducted three focus groups with participants stratified by profession, which included oncologists, radiotherapists, oncology residents, and nurses. A discussion guide was used to generate discussion about multiple aspects of current clinical processes at ORCI. Audio recordings were transcribed and translated to English, and data were analyzed using the framework method. RESULTS A total of 21 participants helped identify institutional and systemic factors that were internal and external to the clinical systems at ORCI that may affect guideline-concordant care. These can be categorized into the following: strengths and facilitators, barriers, and suggestions for improvement. Internal facilitators include multidisciplinary patient management, government-sponsored free cancer care, community engagement, and providers’ motivation for continuous learning and improvement. Internal barriers include interdepartmental and interinstitutional communication gaps, resource limitations for specialized services, high patient volumes, and patient misconceptions and nonadherence. Participants offered many practical suggestions for improving clinical systems at ORCI. CONCLUSION Our results highlight several barriers and facilitators within and outside of the clinical systems at ORCI that may affect the uptake of the National Cancer Treatment Guidelines. Findings have been used to recommend quality improvement and environmental restructuring measures at ORCI that will inform the broader guideline implementation strategy.
