Optimizing cervical cancer care in resource-constrained developing countries by tailoring community prevention and clinical management protocol

Development and Implementation of a Simulation-Based Educational Workshop on Gynecological Brachytherapy: Pilot Study at a National Meeting

PURPOSE

Despite the importance of brachytherapy in the curative treatment of locally advanced cervical cancer, reviews of practice patterns in the United States have identified a decline in brachytherapy use in clinically appropriate patient populations. A survey of radiation oncologists identified lack of time and lack of guidance as barriers. To address these barriers, the purpose of this study was to develop a simulation-based educational (SBE) gynecologic brachytherapy workshop.

METHODS AND MATERIALS

The SBE gynecologic brachytherapy workshop was developed with expertise from 2 institutions, combining procedural simulation with a practical discussion of brachytherapy applicator insertion techniques. The primary outcome was feasibility of workshop deployment, defined as completion of all workshop components in the time allotted. Preworkshop and postworkshop surveys were also administered to assess efficacy, a secondary outcome.

RESULTS

The workshop took place at a national radiation oncology meeting, and all workshop components were completed in the 2 hours allotted. SBE stations focused on (1) fiducial placement, (2-3) applicator selection, (4) suturing, and (5) pelvic examination and applicator placement. Fourteen participants completed surveys. Respondents included residents and attending physicians. More than 50% of respondents were from academic practices and practiced gynecologic brachytherapy weekly or more. Curricular objectives for this workshop were for ≥20% trainees to report increased confidence in practice and ≥20% of trainees to report increased familiarity with applicators. After participation in the workshop, confidence in applicator choice improved in 9 of 13 participants (69%), confidence in complication management improved in 8 of 13 participants (62%), and familiarity with applicators improved in 7 of 13 participants (54%). These differences were statistically significant at α = .05.

CONCLUSIONS

This study demonstrated feasibility in using simulation for gynecologic brachytherapy education at a national meeting. Although most respondents were experienced in brachytherapy, more than half reported increased confidence and familiarity with aspects of the procedure after the workshop. Future work should address interstitial needle placement and improved time management of workshop stations.

Cervical cancer screening in a low-resource setting: a pilot study on an HPV-based screen-and-treat approach

Cervical cancer (CC) is the leading cause of cancer‐related death among women in sub‐Saharan Africa, primarily because of limited access to effective screening and preventive treatment. Our aim was to assess the feasibility of a human papillomavirus (HPV)‐based CC screen‐and‐treat approach in a low‐resource context. We recruited 1012 women aged 30–49 years through a CC screening campaign conducted in the District Hospital of Dschang, Cameroon. Participants performed HPV self‐sampling, which was tested for high‐risk HPV (HR‐HPV) DNA using the point‐of‐care Xpert HPV assay. All HPV‐positive women were invited for visual inspection with acetic acid and Lugol's iodine (VIA/VILI) to exclude CC or enable triage. A cervical sample for histological analysis was also collected. Women positive for HPV 16/18/45 and for other HR‐HPV with pathological VIA/VILI were selected to undergo treatment with thermocoagulation. The HPV prevalence in the study population was 18.5% (n = 187); of these cases, 20 (10.6%), 42 (22.3%) and 140 (74.9%) were positive for HPV16, HPV18/45 and other HR‐HPV types, respectively. Overall, 107/185 (57.8%) VIA/VILI examinations were classified as pathological and 78 (42.2%) as normal. Women positive for HPV16/18/45 were 4.2 times more likely to harbor cervical intraepithelial neoplasia grade 2 or worse (CIN2+) than those with other HPV types. The specificity of HPV 16/18/45 genotypes for detection of high‐grade lesions among HR‐HPV positive women was higher than that of VIA/VILI in all age groups. The sensitivity and specificity of VIA/VILI in detecting CIN2+ among HPV positive women were 80% and 44%, respectively. Overall, 110/121 screen‐positive women (90.9%) were eligible for, and were treated with, thermocoagulation. An HPV‐based screen‐and‐treat approach is feasible in a low‐resource context and may contribute to improving the effectiveness of CC prevention programs. Immediate thermocoagulation treatment for women who are HPV16‐ and/or HPV18/45‐positive is a practical approach for the treatment of CIN2+. The combination of HPV‐testing and VIA/VILI for CC screening might reduce overtreatment.
