Resource-Stratified Guideline-Based Cancer Care Should Be a Priority: Historical Context and Examples of Success

Using context-specific evidence to inform resource-stratified cancer guidelines: A call for a new approach

Clinical practice guidelines are widely used in oncology to guide clinical decision making and inform health policy and planning. In recent years, the National Comprehensive Cancer Network and the American Society of Clinical Oncology, as well as other international groups, have developed resource-stratified guidelines to guide clinicians and policymakers on cancer diagnosis and management in settings with various levels of resource constraints. Current methods for developing resource-stratified guidelines rely heavily on supporting evidence originating from high-income countries. In this commentary, the authors discuss limitations of the existing methods to develop resource-stratified guidelines and offer perspective on ways to strengthen the guidelines and their evidence base. Pulling from conceptual frameworks in the health policy domain, the authors outline a more inclusive approach to evidence synthesis that seeks to integrate the growing volume of cancer research emerging from low- and middle-income countries. The authors also introduce a revised evidence framework that provides transparency into the generalizability of evidence within the guidelines. These changes have the potential to enhance resource-stratified guidelines and bring us one step closer to the goal of evidence-based guidelines that are appropriate for diverse settings and unique patient populations across the world.

Expanding Cervical Cancer Screening in Mozambique: Challenges Associated With Diagnosing and Treating Cervical Cancer

PURPOSE

Mozambique has one of the highest burdens of cervical cancer globally. Treatment options are few as most women present with advanced disease, and there are limited trained health professionals and health care resources. The objective of this study was to describe the outcomes of women diagnosed with invasive cancer as part of the Mozambican women undergoing cervical cancer screening with human papillomavirus (HPV) testing in conjunction with family planning services (MULHER) study.

MATERIALS AND METHODS

Women age 30-49 years were prospectively enrolled in the MULHER study and offered screening with primary HPV testing followed by treatment of screen-positive women with thermal ablation or excision as appropriate. Women with cervical examination findings suspicious for cancer were referred to one of the three gynecologic oncologists in the country.

RESULTS

Between January 2020 and January 2023, 9,014 women underwent cervical cancer screening and 30 women were diagnosed with cervical cancer. In this cohort, four patients (13.3%) had early-stage disease, 18 (60.0%) had locally advanced disease, one (3.3%) had distant metastatic disease, and seven (23.3%) did not have staging information available. Five patients (16.6%) died without receiving oncologic treatment, and seven patients (23.3%) are still awaiting treatment. Of the remaining 18 patients, three (17.6%) underwent surgery and four (23.5%) received radiotherapy. Eleven (36.7%) patients received only chemotherapy.

CONCLUSION

As cervical screening programs are implemented in low-resource settings, there will likely be an increase in the number of women diagnosed with invasive cervical cancer. Our results in Mozambique demonstrate the need to increase access to advanced surgery, radiation, and palliative care services.
