Guiding Principles for Community Building in Global Oncology.

With the escalating incidence and prevalence of cancer worldwide disproportionately affecting low- and middle-income countries, there is an urgent need for the global oncology community to foster bidirectional partnerships and an equitable exchange of knowledge, resources, and expertise. A dedicated Global Oncology Community of Practice (CoP) can serve as a self-organizing, grassroots approach for members, with common goals and values, to coordinate efforts, maximize impact, and ensure sustainable outcomes. It is imperative, however, when outlining goals and priorities to adhere to an ethical and appropriate framework during community building efforts to avoid perpetuating inequities and power imbalances. This article reviews the core guiding principles for ASCO's Global Oncology CoP which includes responsibility, amplification, accessibility, sustainability, and decolonization.

Colorectal cancer disease profile and treatment patterns at an urban tertiary hospital in Rwanda.

Background: The incidence of colorectal cancer (CRC) in sub-Saharan Africa (SSA) is rising, due to improving cancer registration efforts on one hand and an increasing westernisation of diets and lifestyle on the other as well as increasing rates of comorbidities. Methods: We present data for the clinical characteristics, pathology, treatments received, and survival outcomes of patients diagnosed with CRC at King Faisal Hospital (KFH) between January 2019 and May 2023. KFH is an urban tertiary hospital in Rwanda that provides chemotherapy and surgery to cancer patients. The data were extracted from electronic medical records, imaging and histopathology reports from the patient's time of diagnosis. We plotted Kaplan-Meier estimation of survival, defined as the time from presentation to death, within the study period (2019-2023). Results: Seventy-four patients diagnosed with CRC with complete information were identified in the KFH oncology records. The mean age at diagnosis was 54.6 years, with ages ranging between 22 and 81 years. At diagnosis, 24 (32.4%) patients were less than 50 years old and 29 (39.2%) were females. The rectum (36.5%) was the most common tumour location, and 58.1 tumours were left-sided. Most patients presented with Stage III (41.9%) or IV (35.1%) disease. Adenocarcinoma was the most common histological type (98.6%) including adenocarcinoma not otherwise specified (NOS) (86.5%), mucinous adenocarcinoma (10.8%), signet ring cell carcinoma (1.4%) and followed by squamous cell carcinoma (1.4%). In terms of treatment, 19 (25.7%) patients received only chemotherapy, 43 (58.1%) patients received neo-adjuvant or adjuvant chemotherapy, 9 (12.2%) of patients received both neo-adjuvant and adjuvant chemotherapy, 49 patients (66.2%) underwent surgery and 17 (23%) patients also received radiation. At the end of the follow up period, 63 (85.1%) patients remained in surveillance, 10 (13.5%) patients died, and 1 (1.3%) patient was lost to follow up. Mean overall survival was 45.5 (SD ± 2.0) months. Conclusion: CRC patients presented at an advanced stage and required complex treatment regimens at KFH. Further epidemiologic and molecular research is needed to characterise CRC incidence and presentation at a national level in Rwanda as increasing westernisation continues to change the face of CRC in urban areas of SSA.

Low-Value Surgical Procedures in Low- and Middle-Income Countries: A Systematic Scoping Review.

Importance: Overuse of surgical procedures is increasing around the world and harms both individuals and health care systems by using resources that could otherwise be allocated to addressing the underuse of effective health care interventions. In low- and middle-income countries (LMICs), there is some limited country-specific evidence showing that overuse of surgical procedures is increasing, at least for certain procedures. Objectives: To assess factors associated with, extent and consequences of, and potential solutions for low-value surgical procedures in LMICs. Evidence Review: We searched 4 electronic databases (PubMed, Embase, PsycINFO, and Global Index Medicus) for studies published from database inception until April 27, 2022, with no restrictions on date or language. A combination of MeSH terms and free-text words about the overuse of surgical procedures was used. Studies examining the problem of overuse of surgical procedures in LMICs were included and categorized by major focus: the extent of overuse, associated factors, consequences, and solutions. Findings: Of 4276 unique records identified, 133 studies across 63 countries were included, reporting on more than 9.1 million surgical procedures (median per study, 894 [IQR, 97-4259]) and with more than 11.4 million participants (median per study, 989 [IQR, 257-6857]). Fourteen studies (10.5%) were multinational. Of the 119 studies (89.5%) originating from single countries, 69 (58.0%) were from upper-middle-income countries and 30 (25.2%) were from East Asia and the Pacific. Of the 42 studies (31.6%) reporting extent of overuse of surgical procedures, most (36 [85.7%]) reported on unnecessary cesarean delivery, with estimated rates in LMICs ranging from 12% to 81%. Evidence on other surgical procedures was limited and included abdominal and percutaneous cardiovascular surgical procedures. Consequences of low-value surgical procedures included harms and costs, such as an estimated US $3.29 billion annual cost of unnecessary cesarean deliveries in China. Associated factors included private financing, and solutions included social media campaigns and multifaceted interventions such as audits, feedback, and reminders. Conclusions and Relevance: This systematic review found growing evidence of overuse of surgical procedures in LMICs, which may generate significant harm and waste of limited resources; the majority of studies reporting overuse were about unnecessary cesarean delivery. Therefore, a better understanding of the problems in other surgical procedures and a robust evaluation of solutions are needed.

HIV and Early Treatment Outcomes Among Women With Cervical Cancer Treated With Concurrent Chemoradiation in Tanzania.

PURPOSE: Cervical cancer (CC) is the leading malignancy in Tanzania. Low-income countries are faced with double epidemics of HIV and CC. This study aimed to investigate how HIV and cancer stage at diagnosis affect early treatment outcomes among women with CC treated with concurrent chemoradiation in Tanzania in the highly active antiretroviral therapy era. MATERIALS AND METHODS: This was a prospective cohort study of patients newly diagnosed with CC at the Ocean Road Cancer Institute from November 2019 to January 2020. The tumor response was assessed using RECIST 3 months post-treatment. The tumor response was categorized as a complete or partial response according to the ultrasound and pelvic examination findings. The univariate and multivariate logistic regression explained the relationship between several covariates (age, stage, HIV status, equivalent dose in 2 Gy fractions, chemotherapy cycles, and treatment time) and treatment response. RESULTS: A total of 102 patients with CC were included in this study at baseline. After adjusting for other covariates, only completion of treatment within 56 days (odds ratio [OR], 9.23; 95% CI, 1.53 to 55.85; P = .016) and receiving at least three cycles of cisplatin (OR, 5.6; 95% CI, 1.47 to 21.34; P = .012) were significantly associated with complete tumor response. HIV status was not significantly associated with complete tumor response (OR, 1.534; 95% CI, 0.424 to 5.545; P = .5144). CONCLUSION: Early treatment response was independent of HIV status. With wide coverage of anitretroviral therapy, patients with HIV can receive radical treatment and have the same early outcomes as their HIV-negative counterparts.

Multidisciplinary approach to cancer care in Rwanda: the role of tumour board meetings.

Introduction: Cancer treatment is complex and necessitates a multidisciplinary approach. Tumour Board Meetings (TBMs) provide a multidisciplinary platform for health care providers to communicate about treatment plans for patients. TBMs improve patient care, treatment outcomes and, ultimately, patient satisfaction by facilitating information exchange and regular communication among all parties involved in a patient's treatment. This study describes the current status of case conference meetings in Rwanda including their structure, process and outcomes. Methods: The study included four hospitals providing cancer care in Rwanda. Data gathered included patients' diagnosis, number of attendance and pre-TBM treatment plan, as well as changes made during TBMs, including diagnostic and management plan changes. Results: From 128 meetings that took place at the time of the study, Rwanda Military Hospital hosted 45 (35%) meetings, King Faisal Hospital had 32 (25%), Butare University Teaching Hospital (CHUB) had 32 (25%) and Kigali University Teaching Hospital (CHUK) had 19 (15%). In all hospitals, General Surgery 69 (29%) was the leading speciality in presenting cases. The top three most presented disease site were head and neck 58 (24%), gastrointestinal 28 (16%) and cervix 28 (12%). Most (85% (202/239)) presented cases sought inputs from TBMs on management plan. On average, two oncologists, two general surgeons, one pathologist and one radiologist attended each meeting. Conclusion: TBMs in Rwanda are increasingly getting recognised by clinicians. To influence the quality of cancer care provided to Rwandans, it is crucial to build on this enthusiasm and enhance TBMs conduct and efficiency.

Media coverage of cancer therapeutics: A review of literature.

BACKGROUND: Information and stories about cancer treatment are increasingly available to patients and the general public through lay media, websites, blogs and social media. While these resources may be helpful to supplement information provided during physician-patient discussions, there is growing concern about the extent to which media reports accurately reflect advances in cancer care. This review aimed to understand the landscape of published research which has described media coverage of cancer treatments. METHODS: This literature review included peer-reviewed primary research articles that reported how cancer treatments are portrayed in the lay media. A structured literature search of Medline, EMBASE and Google Scholar was performed. Potentially eligible articles were reviewed by three authors for inclusion. Three reviewers, each independently reviewed eligible studies; discrepancies were resolved by consensus. RESULTS: Fourteen studies were included. The content of the eligible studies reflected two thematic categories: articles that reviewed specific drugs/cancer treatment (n = 7) and articles that described media coverage of cancer treatment in general terms (n = 7). Key findings include the media's frequent and unfounded use of superlatives and hype for new cancer treatments. Parallel to this, media reports over-emphasize potential treatment benefits and do not present a balanced view of risks of side effects, cost, and death. At a broad level, there is emerging evidence that media reporting of cancer treatments may directly impact patient care and policy-making. CONCLUSIONS: This review identifies problems in current media reports of new cancer advances - especially with undue use of superlatives and hype. Given the frequency with which patients access this information and the potential for it to influence policy, there is a need for additional research in this space in addition to educational interventions with health journalists. The oncology community - scientists and clinicians - must ensure that we are not contributing to these problems.

Noise levels associated with urban land use types in Kigali, Rwanda.

Noise pollution poses a serious threat to public health and continues to grow in extent, frequency, and severity due to the rapid population growth and urbanization, and this is of particular concern in developing countries such as Rwanda. However, data on noise pollution levels, noise laws and regulations are, however, lacking in Rwanda. We assessed the effect of land-use type during a two-month period at nine sites: three commercial sites, three passenger-car parking sites, two road junction sites, and one reference site (Car-Free Zone) in Rwanda. We collected data on noise pollution during weekdays (Monday, Wednesday, and Friday) and Weekends (Saturday and Sunday) in the morning (7h00-10h00), around noon (11h00-14h00), and in the evening (15h00-18h00). The mean noise levels were higher during weekdays (60-80) A-weighted decibels (dB) (A)) than during weekends (50-70 dB (A)). We recorded the lowest noise level at Kigali car-free zone in the morning (34.4 dB (A)) and the highest noise level at Nyabugogo passenger-car parks in the evening (111.2dB (A)). Spatial variation of noise levels interpolated for Kigali City shows higher noise levels (hotspot) in the outskirts of Kigali, Remera and Kimironko. Noise levels recorded in Kigali exceeded the World Health Organization permissible daytime limits during both weekdays and weekends at all land-use types except the car-free zone site. Our results indicate that Kigali residents are exposed to high levels of noise, and urgent development of noise pollution monitoring programs and control measures in Rwanda is required.

Trends of Molecular Testing for Lung Cancer at the King Faisal Hospital, Kigali: Therapeutic and Survival Implications.

Introduction: Lung cancer is the leading cause of cancer mortality worldwide, both in high and low resource settings. Knowledge has been generated elsewhere regarding molecular subtyping and subsequent targeted therapy development, contributing substantially to patient survival. Little is known on the data around lung cancer and its treatment outcomes in Sub-Saharan Africa. This study describes the experience in lung cancer diagnosis, molecular and biomarker testing, and treatment for advanced cases in a single institution in East Africa, between the years 2019 and 2021. Methods: This was a retrospective observational study evaluating patients with metastatic (stage IV) lung cancer. Data on patient demographics, histologic diagnosis, molecular and biomarker testing, and treatment details and outcomes were collected. Molecular test results were reported as positive if there were biomarkers identified (e.g., EGFR, ALK, programmed death-ligand 1), and patients who had negative test results were reported as negative for biomarkers. Results: A total of 14 patients were diagnosed with having stage IV disease, and all were proposed to undergo molecular testing. For 12 (86%) patients who were able to have molecular testing done, EGFR and programmed death-ligand 1 were the most common with 66.7% (N = 8) of tissues with either finding. For all 14 patients, treatment changes were made for eight patients (57.1%) after being primarily placed on a combination of paclitaxel and carboplatin for an average of six cycles. Changing treatment significantly improved the 2-year overall survival (85% versus 25%, p = 0.0006). Conclusions: Despite being the number one cause of mortality, gains are being made in poor-resource settings to improve the survival of patients with advanced lung cancers. Limitations to this quest remain misdiagnosis and delayed diagnosis and resource constraints for both molecular testing and subsequent treatments.
