Jordan, a lower- to middle-income country, is relatively small, but with rapidly growing population and a challenged economy. Cancer is a growing health care problem and currently ranked second, after cardiovascular diseases, as a cause of death. Jordan's national cancer registry continues to suffer from problems mostly related to long lag time in reporting, absence of outcome data, and accurate staging. The number of new patients with cancer diagnosed in Jordan is increasing at an expected, none disturbing rate, fueled by population growth, improving life expectancy, changing population structure that hosts more older population, high rate of obesity, smoking, and lack of adequate exercise. However, age-standardized rate for cancer incidence is significantly lower than Western societies, yet, mortality rate is higher. Despite efforts, cancer is still diagnosed at more advanced stages and at younger age. The Jordan breast cancer program represents a great example of opportunistic screening that led to significant downstaging of breast cancer. Efforts to evaluate the feasibility of screening programs for colorectal and lung cancers are underway. Tremendous efforts resulted in the execution of the largest clinical cancer genetics program in the region that helps identify patients and at-risk relatives for hereditary cancers. Low-resourced countries, including Jordan, will not be able to keep up with the rapidly increasing cost of cancer care. A better access to clinical trials and moving cancer care to ambulatory settings should offset some of this cost. A cancer control program that addresses all issues of cancer care from screening and early detection, through active cost-effective treatment that assures wider access to palliative care, hospice, and survivorship programs under an expanded universal health coverage, is an urgent national health priority.

Purpose: The growing cancer burden in Botswana has been linked to aging, lifestyle factors, and high HIV infection prevalence. The government has designated four geographically distributed hospitals as public oncology centers (POCs). A needs assessment was undertaken to ascertain the characteristics of cancer care at these centers.

Methods: A multisite cross-sectional survey study of cancer care was conducted with oncology staff at Princess Marina Hospital (PMH), Nyangabgwe Referral Hospital (NRH), Sekgoma Memorial Hospital (SMH), and Letsholathebe II Memorial Hospital (LMH) from February to April 2021. At each POC, a focal person (experienced nurse working in oncology) identified relevant oncology staff and confirmed service availability.

Results: Only PMH and NRH had a broad array of diagnostic, surgical, and treatment services. In addition, PMH was the only center with a a dedicated inpatient oncology service, a multidisciplinary committee to review patients, and a palliative care team. To support the only national cancer screening program, for cervical cancer, all POCs offered Pap tests. Mammography, available at PMH and NRH, was used solely for diagnosis. Patients from POCs requiring radiation therapy were referred to Gaborone Private Hospital at government expense. For perceived service availability, 51 staff, mainly oncologists, physicians, and nurses, were surveyed (66% based at PMH). Perceptions of services revealed a few concerns, for example, numerous staff considered hysterectomies for cervical cancer available when they were only performed at PMH.

Conclusion: Despite Botswana's efforts to increase the proximity of cancer services to patients, there are marked gaps, particularly at the two district-level POCs, SMH and LMH. In the future, SMH and LMH could provide selected services for specific prevalent cancers on-site, as well as follow-up and palliative care.

Purpose: To review the economic burden assessment of cervical cancer in low- and middle-income countries (LMICs) and use the findings to develop a pragmatic, standardized framework for such assessment.

Methods: We first systematically reviewed articles indexed in scientific databases reporting the methodology for collecting and calculating costs related to the cervical cancer burden in LMICs. Data on study design, costing approach, cost perspective, costing period, and cost type (direct medical costs [DMC], direct nonmedical costs [DNMC], and indirect costs [IC]) were extracted. Finally, we summarized the reported limitations in the methodology and used the solutions to inform our framework.

Results: Cervical cancer treatment costs across LMICs vary greatly and can be extremely expensive, up to 70,968 International US dollars. Economic and financial assessment methods also vary greatly across countries. Of the 28 reviewed articles, 25 studies reported DMC for cervical cancer treatment by extracting cost information from billing or insurance databases (eight studies), conducting surveys (five), and estimating the costs (12). Only 11 studies-mainly through surveys-reported DNMC and IC. The economic burden assessment framework includes health care/payer and societal perspectives (DMC, DNMC, IC, and human capital loss) across the cervical cancer screening and treatment continuum. To assess health care/payer costs, we recommend combining the predefined treatment standards with actual local treatment practices, multiplied by unit costs. To assess societal costs, we recommend conducting a cost survey in line with a standardized yet adaptable protocol.

Conclusion: Our standardized, pragmatic framework allows assessment of economic and financial burden of cervical cancer in LMICs despite the different levels of available resources across countries. This framework will facilitate global comparisons and monitoring and may also be applied to other cancers.

Purpose: To describe the global landscape of clinical research into interventions for gastroesophageal cancers (GECs), with examination of trial characteristics, geographic distribution of trial sites, and factors associated with trial termination.

Methods: We queried ClinicalTrials.gov to identify all completed or terminated phase III interventional studies investigating GECs (esophageal squamous cell carcinoma [ESCC], esophageal adenocarcinoma [EAC], gastroesophageal junctional [GEJ], and gastric adenocarcinoma). Data on all reported trial characteristics were extracted. Pearson's chi-square and Fisher's exact tests were used to compare differences in completed and terminated trials. Multivariate logistic regression evaluated predictors of termination.

Results: A total of 179 trials were identified; of these, 90% were therapeutic. Most included sites in Asia (61%) and Europe (32%); few included sites in Africa (4%). Thirty percent included sites in low- and middle-income countries (LMICs). Most (70%) focused on gastric or GEJ adenocarcinoma, 13% on EAC and ESCC, and 9% on ESCC alone. Sixteen percent (n = 29) of trials terminated prematurely. In multivariate analysis, study site number, location of recruitment sites, and patient population emerged as predictors of termination. Trials recruiting from US-based sites were more likely to terminate (odds ratio [OR], 7.22 [95% CI, 1.59 to 32.69]). Trials conducted exclusively in LMICs were less likely to terminate (OR, 0.04 [95% CI, 0.01 to 0.59] v conducted in high-income countries [HICs] alone). Studies on ESCC were more likely to terminate (OR, 17.74 [95% CI, 1.49 to 210.69]).

Conclusion: Although 80% of GECs occur in LMICs, trial activity disproportionately occurs in HICs. Few trials focus on EAC/ESCC despite being highly fatal, highlighting an unmet need. Overall, this study highlights (1) a missed opportunity to recruit patients from high-incidence regions globally; and (2) a pressing need for increasing funding, infrastructure, and support for GEC trials in LMICs.

Purpose: Breast cancer is the leading type of cancer diagnosed and the second leading cause of cancer-related death in Ghana. Mammography and ultrasound have proven benefits in the early detection of breast cancer. This study evaluates mammography, breast ultrasound, and radiology work force availability throughout Ghana.

Methods: A survey was administered to all hospitals in Ghana from November 2020 to October 2021. Mammography, breast ultrasound services, and the number of radiologists were assessed. For mammography, the number performed per month, cost incurred by the patient, where images were read, and how long it took to receive reports were also assessed. Health Facilities Regulatory Authority records on diagnostic centers were obtained to identify additional in-country breast imaging services.

Results: Three hundred and twenty-eight of 346 hospitals participated in the survey (95%). Only 21 hospitals reported on-site mammography. One hospital reported performing >100 mammographies per month. The average cost to the patient ranged from 100 to 500 Cedis ($17-87 US dollars [USD]), although three hospitals performed mammography at no cost. An additional 10 mammography machines were identified at diagnostic centers throughout the country, with 41.3% of the female population living within 1 hour of mammography services. There were 135 hospital-based breast ultrasound services identified with 69.5% of the female population living within 1 hour of these services. There were an additional 190 ultrasound machines at diagnostic centers. There were 96 in-country radiologists identified.

Conclusion: Although there is limited availability and utilization of mammography in Ghana, there is more readily available ultrasonography. A focus on increasing breast cancer early diagnostic capabilities with breast ultrasound should be prioritized in addition to further expansion of the radiology workforce.

Purpose: Longer time between breast cancer (BC) diagnosis and treatment initiation is associated with poorer survival, and this may be a factor behind disparities in global survival rates. We assessed time to BC treatment in the Kathmandu Valley, Nepal, including factors associated with longer waiting times and their impact on survival.

Methods: We conducted a retrospective population-based study of BC cases recorded in the Kathmandu Valley Population-Based Cancer Registry between 2018 and 2019. Fieldwork survey through telephone was undertaken to collect additional sociodemographic and clinical information. Logistic regression was performed to identify factors associated with longer time to treatment, and Kaplan-Meier and Cox proportional hazard regression was used to examine survival time and evaluate the association between longer time to treatment and survival.

Results: Among the 385 patients with BC, one third waited >4 weeks from diagnosis to initial treatment. Lower education was associated with longer time to treatment (adjusted odds ratio, 1.63 [95% CI, 1.03 to 2.60]). The overall 3-year survival rate was 88.6% and survival was not associated with time to treatment (P = .50). However, advanced stage at diagnosis was associated with poorer survival (adjusted hazard ratio, 4.09 [95% CI, 1.27 to 13.23]). There was some indication that longer time to treatment was associated with poorer survival for advanced-stage patients, but data quality limited that analysis.

Conclusion: In the Kathmandu Valley, Nepal, women with a lower education tend to wait longer from BC diagnosis to treatment. Patients with advanced-stage BC had poorer survival, and longer waiting time may be associated with poorer survival for women diagnosed with advanced-stage disease.
