Impact of Waiting Time and Treatment Duration on Short-Term Outcomes for Patients With Locally Advanced Cervical Cancer at the Uganda Cancer Institute: The Challenges in Resource-Limited Settings

PURPOSE Cervical cancer remains a significant public health burden, especially in sub-Saharan Africa. The waiting time and treatment duration are key indicators of quality in oncology care, and guidelines recommend that chemoradiation for patients with locally advanced cervical cancer (LACC) should be completed within 8 weeks. This study aimed to quantify waiting times and treatment durations for LACC at the Uganda Cancer Institute and identify bottlenecks in the radiotherapy treatment pathway. MATERIALS AND METHODS This prospective study involved 196 patients with LACC. The department’s treatment protocol for LACC allows either conventional fractionated radiotherapy (CFRT) at 50 Gy/25# or hypofractionated radiotherapy (HFRT) at 45 Gy/15#, followed by brachytherapy at 24 Gy/3#. Nine key treatment milestones were documented from diagnosis to brachytherapy completion. The impact of social determinants of health on waiting times was analyzed. Responses were assessed 6 months after treatment completion. RESULTS Patients spent a median delay time of 41 days and a median waiting time of 88 days. The median external beam radiation therapy duration was 40 days for CFRT, compared with 24 days for HFRT. The median waiting time before initiating brachytherapy was 40 days, leading to an overall treatment duration of 85 days for CFRT and 66 days for HFRT. Only 18% of patients on CFRT and 37% of patients on HFRT completed within timelines. The proportions of patients with either waiting times or treatment duration of ≤8 weeks who had complete responses were comparatively greater than those who started treatments after >8 weeks. CONCLUSION Only 25% completed treatment within the recommended timelines. The long waiting time for brachytherapy makes it impossible to finish within timelines. Strategies to expedite access to brachytherapy are necessary to enhance radiotherapy quality.

The social and economic impacts of cervical cancer on women and children in low‐ and middle‐income countries: A systematic review

AbstractBackgroundThere is limited knowledge on the social and economic impacts of a diagnosis of cervical cancer on women and children in low‐ and middle‐income countries (LMICs).ObjectivesTo determine the social and economic impacts associated with cervical cancer among women and children living in LMICs.Search strategyThe MEDLINE, PsychInfo, CINAHL, Pais International, and CAB Global Health databases were systematically searched to retrieve studies up to June 2021.Selection criteriaStudies were included if they reported on either the social or economic impacts of women or children in a LMIC.Data collection and analysisData was independently extracted by two co‐authors. The authors performed a quality assessment on all included articles.Main resultsIn all, 53 studies were included in the final review. Social impacts identified included social support, education, and independence. Economic impacts included employment and financial security. No study reported the economic impact on children. Studies that utilized quantitative methods typically reported more positive results than those that utilized qualitative methods.ConclusionsAdditional mixed‐methods research is needed to further understand the social support needs of women with cervical cancer. Furthermore, research is needed on the impact of a mother's diagnosis of cervical cancer on her children.

Implementing Smartphone-Based Telemedicine for Cervical Cancer Screening in Uganda: Qualitative Study of Stakeholders’ Perceptions

Background In Uganda, cervical cancer (CaCx) is the commonest cancer, accounting for 35.7% of all cancer cases in women. The rates of human papillomavirus vaccination and CaCx screening remain low. Digital health tools and interventions have the potential to improve different aspects of CaCx screening and control in Uganda. Objective This study aimed to describe stakeholders’ perceptions of the telemedicine system we developed to improve CaCx screening in Uganda. Methods We developed and implemented a smartphone-based telemedicine system for capturing and sharing cervical images and other clinical data, as well as an artificial intelligence model for automatic analysis of images. We conducted focus group discussions with health workers at the screening clinics (n=27) and women undergoing screening (n=15) to explore their perceptions of the system. The focus group discussions were supplemented with field observations and an evaluation survey of the health workers on system usability and the overall project. Results In general, both patients and health workers had positive opinions about the system. Highlighted benefits included better cervical visualization, the ability to obtain a second opinion, improved communication between nurses and patients (to explain screening findings), improved clinical data management, performance monitoring and feedback, and modernization of screening service. However, there were also some negative perceptions. For example, some health workers felt the system is time-consuming, especially when it had just been introduced, while some patients were apprehensive about cervical image capture and sharing. Finally, commonplace challenges in digital health (eg, lack of interoperability and problems with sustainability) and challenges in cancer screening in general (eg, arduous referrals, inadequate monitoring and quality control) also resurfaced. Conclusions This study demonstrates the feasibility and value of digital health tools in CaCx screening in Uganda, particularly with regard to improving patient experience and the quality of screening services. It also provides examples of potential limitations that must be addressed for successful implementation.
