RESUMEN

INTRODUCTION: The formative period of the specialty of gynecologic oncology was from 1968 to 1972 and became a board-certified specialty in 1973. During this formation there were no Black physicians participating in this process. We chronicle and document the incorporation of the first three board-certified Black physicians in the specialty of gynecologic oncology here for historical purposes. METHODS: We highlight the hostile climate experienced by Black physicians before and during the formation of gynecologic oncology, review the acceptance and training of the first three Black physicians in the specialty and recognize their significant contributions to the field. RESULTS: The biographies and the narrative of these men describe their impact and contribution to medicine. We chronicle the historic presence of the first board-certified Black gynecologic oncologists and pelvic surgeons in the United States. CONCLUSION: These three men represent the Black Founding Fathers of gynecologic oncology. Their perseverance in the face of adversity and commitment to excellence have left an indelible impact on the institutions that they developed, the individuals that they trained, and the patients that they served.

RESUMEN

INTRODUCTION: Endometrial cancer is the most commonly diagnosed female genital tract malignancy in the United States of America. Racial disparities surrounding this particular disease have been extensively investigated for over 26-years. We sought to determine if research in this area has led to any significant improvements in this disparity. METHODS: We performed a rapid systematic review of English language publications on racial disparities in endometrial cancer among African American (AAW) and white American women (WAW), from 1997 to 2023. We looked at trends in incidence and survival; impact of known poor prognostic factors (stage at diagnosis, histological subtypes, grade); co-morbidities; differences in treatment (surgery, radiation and chemotherapy); socioeconomic factors; differences in biological and genetic markers; and policies/declarations. RESULTS: During the period under review (1997-2023), there was a notable increase in both disease incidence (39%) and mortality (26%) rates for AAW, in comparison to WAW among whom the incidence rates increased by 2% and mortality rates rose, but 9% less than for AAW. It should be noted that the current incidence rate of 29.4% in AAW represent a reversal of what is was 26-years ago, when the incidence rate was 17.8%. In comparison to WAW, AAW had a higher prevalence of poor prognostic variables, more co-morbidities, lower income levels, less insurance coverage, and were more frequently under treated with surgery, chemotherapy and radiation. To date no actionable molecular/genetic markers have been identified. We were unable to locate any published recommendations or active programs of implementation strategies/policies designed to effectively mitigate the documented racial disparity. CONCLUSION: Racial disparities in disease incidence and mortality in endometrial cancer rates between WAW and AAW have widened during a 26-year period of robust research, suggesting that current research alone is not enough to eliminate this disparity. Based on this rapid systematic review we have identified and analyzed the impact of causation variables on this disparity. Additionally, we have made strong and pertinent recommendations for the benefit of mitigating this escalating racial disparity.

RESUMEN

BACKGROUND: HIV infection is associated with a higher incidence of precancerous cervical lesions and their progression to invasive cervical cancer (ICC). Zambia is a global epicenter of HIV and ICC, yet the overall burden of cervical pre-cancer [cervical intraepithelial neoplasia 3 (CIN3)] and ICC among its HIV positive adult female population is unknown. The objective of this study was to determine the burden of cervical disease among HIV positive women in Zambia by estimating the number with CIN3 and ICC. METHODS: We conducted a cross-sectional study among 309 HIV positive women attending screening in Lusaka (Zambia's most populated province) to measure the cervical disease burden by visual inspection with acetic acid enhanced by digital cervicography (DC), cytology, and histology. We then used estimates of the prevalence of CIN3 and ICC from the cross-sectional study and Spectrum model-based estimates for HIV infection among Zambian women to estimate the burden of CIN3 and ICC among HIV positive women nationally. RESULTS: Over half (52 %) of the study participants screened positive by DC, while 45 % had cytologic evidence of high grade squamous intraepithelial lesions (SIL) or worse. Histopathologic evaluation revealed that 20 % of women had evidence of CIN2 or worse, 11 % had CIN3 or worse, and 2 % had ICC. Using the Spectrum model, we therefore estimate that 34,051 HIV positive women in Zambia have CIN3 and 7,297 have ICC. CONCLUSIONS: The DC, cytology, and histology results revealed a large cervical disease burden in this previously unscreened HIV positive population. This very large burden indicates that continued scale-up of cervical cancer screening and treatment is urgently needed.

RESUMEN

BACKGROUND: Following the launch of the World Health Organization's Strategy to accelerate the elimination of cervical cancer, diagnosis is expected to increase, especially in low- and middle-income countries (LMICs). A well-integrated surgical system is critical to treat cervical cancer. Two major approaches have been employed to build human capacity: task-sharing and training of gynecologic oncologists (GynOncs). OBJECTIVES: This review aimed to explore existing literature on capacity-building for surgical management of early-stage gynecologic cancers. SEARCH STRATEGY: The search strategy was registered on Open Science Framework (doi 10.17605/OSF.IO/GTRCB) and conducted on OVID Medline, Embase, Global Index Medicus, and Web of Science. Search results were exported and screened in COVIDENCE. SELECTION CRITERIA: Studies published in English, Spanish, French, and/or Portuguese conducted in LMIC settings evaluating capacity building, task-sharing, or outcomes following operation by subspecialists compared to specialists were included. DATA COLLECTION AND ANALYSIS: Results were synthesized using narrative synthesis approach with emergence of key themes by frequency. MAIN RESULTS: The scoping review identified 18 studies spanning our themes of interest: capacity building, subspecialized versus non-subspecialized care, and task-shifting/-sharing. CONCLUSIONS: A multilayered approach is critical to achieve the WHO Strategy to Eliminate Cervical Cancer. Capacity-building and task-sharing programs demonstrate encouraging results to meet this need; nevertheless, a standardized methodology is needed to evaluate these programs, their outcomes, and cost-effectiveness.

RESUMEN

Introduction: Cancellations of elective surgery in low-and middle-income countries (LMIC) are common and a major hindrance for patients who are in need of surgical therapeutic modalities. This is especially important in the context of scaling up needed surgical interventions for gynaecological cancer care. There is a knowledge gap in the literature related to cancellation of gynaecologic oncology surgeries in LMIC, where there is enormous need for this specific cancer surgical capacity. We report in an observational descriptive fashion, our experience at the UTH/CDH in Lusaka, Zambia, on the causes of surgical cancellations in gynaecologic oncology. Methods: From January 1, 2021 through June 31, 2023, we retrospectively evaluated the surgical registry for gynaecologic oncology at the UTH/CDH in Lusaka, Zambia to assess the number and causes of surgical cancellations. Results: There were a total of 66 (16.96%) surgical cancellations out of 389 scheduled gynaecologic oncology cases. Lack of available blood and/or low haemoglobin was the most frequent cause of surgical cancellations, 27 cases (40.90%). Conclusion: We highlight in our series that the lack of blood, leading to surgical cancellations was the most frequent impediment related to performing scheduled gynaecologic oncology surgical procedures. As gynaecologic oncology services scale up in LMIC, given the radical nature of surgery and its association with blood loss, it is incumbent on the entire clinical ecosystem to address this issue and to develop mitigating strategies, specific to their respective resource setting.

RESUMEN

This editorial was prompted by a criticism of our inability to identify all existing local oncologic human resources prior to the initiation of a women's cancer care platform in the Democratic Republic of the Congo. We discuss the act of parachuting, i.e., intermittent visits by investigators from high-income countries to low-and middle-income countries, its dichotomization (positive and negative), role in bilateral collaborations between high-income and low-and middle-income countries, contributing etiologies and potential harms. Lastly, we highlight our use of parachuting to successfully transfer breast and cervical cancer diagnostic and surgical skills to healthcare providers in a low-income African nation, while simultaneously building clinical infrastructure for women's cancers. We conclude with recommendations that pertain to the development of better research ecosystems in Africa.

RESUMEN

The human, financial, and infrastructural resources required to effectively treat invasive cancer of the cervix are grossly inadequate in the African region, inclusive of a paucity of surgeons capable of performing life-saving radical pelvic surgery for early-stage disease, and the requisite medical ecosystem (blood banking, anesthesia, laboratory, imaging, diagnostics, etc.) Death without treatment, therefore, is a common sequela of cervical cancer in Africa. As African American gynaecologic oncology sub-specialists working in Africa and its Diaspora, we set out to find a way to alter these circumstances. Herein, we provide an overview of our efforts and how they evolved into a novel method of training that rapidly builds surgical capacity for the treatment of early-stage cervical cancer in resource-constrained environments.

RESUMEN

Introduction: The major objective of the study was to compare and contrast a U.S. and Zambian Ob/Gyn residency programme, using uniform metrics, as the basis for an initial exploration of perceived inequities in post-graduate medical education between low- and high-income countries. Methods: Measurements of the following procedures were used to indicate whether minimum standards had been met by trainees in their respective postgraduate programmes: vaginal deliveries; C-sections; abdominal, vaginal and laparoscopic hysterectomies; other laparoscopic surgeries; cancer cases; abortions; obstetrical ultrasounds; cystoscopies; incontinence and pelvic floor surgeries. Evaluations were also made with respect to the presence or absence of an official ultrasound rotation, subspeciality and off-service rotations, protected didactic time and exclusive time on obstetrics and gynaecologic clinical services. Comparisons were made relative to these various categories and the average procedural numbers at each level of training to determine differences in trends and degree of exposure. Results: Minimal procedural requirements were met by both the U.S. and Zambian programmes. For open surgical cases, the minimum standards were higher for the Zambian programme, whereas for procedures associated with the use of high-end technology, such as ultrasound and minimally invasive surgery, minimum standards were higher for the U.S. programme. Conclusion: There were no significant differences in the Zambian and U.S. Ob/Gyn post-graduate training programmes, relative to their respective metrics. A more extensive analysis is required to determine the actual competency levels that are produced by the respective training systems.

RESUMEN

BACKGROUND: The majority of the world's poorest women (income < $1.90/day) reside in fragile, conflict and violence (FCV)-affected countries, like the Democratic Republic of the Congo. Health services in these settings have traditionally focused on immediate relief efforts, communicable diseases and malnutrition. Recent data suggests there is need to widen the focus to include cancer, as its incidence and mortality rates are rising. METHODS: Employing competency-based learning strategies, Congolese health professionals were trained to perform same-day cervical cancer screening and treatment of precancerous lesions of the cervix; same-day clinical breast examination and breast ultrasound diagnostics; surgical treatment of invasive cancers of the breast and cervix; and infusion of cytotoxic chemotherapy. Outpatient breast and cervical cancer care clinics, a chemotherapy suite and surgical theatres were outfitted with equipment and supplies. RESULTS: Combining local and regional hands-on training seminars with wise infrastructure investments, a team of US and Zambian oncology experts successfully implemented a clinical service platform for women's cancers in a private sector health facility in the Democratic Republic of the Congo. CONCLUSION: We forged a novel partnership between oncology health professionals from Africa and its Diaspora, international philanthropic organisations, a cancer medicine access initiative and an established African cancer centre to build women's cancer services in a FVC-affected African setting.

RESUMEN

OBJECTIVES: Surgery is a cornerstone of the management of cervical cancer. Women diagnosed with cervical cancer in sub-Saharan Africa have very little access to specialised (gynaecologic oncology) surgical services. We describe our experiences and challenges of training local general gynaecologists to surgically treat early stage invasive cervical cancer at a private sector healthcare facility in a fragile, low-income African nation. METHODS: Implementation of the training curriculum began with assigned self-directed learning. It continued with on-site training which consisted of preoperative surgical video reviews, pre- and intra-operative assessment of disease status, deconstruction of the designated surgical procedure into its critical subcomponents and trainees orally communicating the steps of the surgical procedure with the master trainers. High-volume repetition of a single surgical procedure over a short time interval, intra-operative bedside mentoring, post-operative case review and mental narration were critical to the process of surgical skills transfer. RESULTS: Nineteen radical abdominal hysterectomies were successfully performed over four training visits; trainees were able to perform the procedure alone after eight cases; surgical complications decreased over time. The trainees have continued to perform the surgical procedures independently. CONCLUSION: Life-saving surgical capacity for the treatment of cervical cancer has been established and sustained at a private sector healthcare facility in a fragile, low-income African setting, through an innovative model of surgical training.

RESUMEN

BACKGROUND: Cancer incidence is increasing worldwide. Over the next 20 years, the growing proportion of cases in low- and middle-income countries (LMICs) will account for an estimated 70% of all cancers diagnosed. The vast majority of cancer patients in LMICs will require chemotherapy, due to the advanced stage of their disease at the time of initial presentation. Unfortunately, the availability of cancer drugs in these environments is sparse, resulting in premature death and years of life lost. In an effort to lay a foundation for women's cancer control in the Democratic Republic of the Congo (DRC), we implemented a programme which combined workforce development, infrastructure creation and cancer drug access. This manuscript reports on our experience with the latter. METHODS: A private sector healthcare facility was selected as the programme implementation site. Workforce capacity was developed through a south-south partnership with an African national cancer centre. Cancer drugs were procured through a global cancer medicine access initiative. RESULTS: A new chemotherapy infusion unit was successfully established at the Biamba Marie Mutombo Hospital in Kinshasa, DRC. A team of Congolese healthcare providers was trained at the Cancer Disease Hospital in Zambia to safely and effectively administer chemotherapy for breast and cervical cancer. Over 100 breast and cervical cancer patients have been treated with 337 courses of chemotherapy, without any serious adverse events. CONCLUSION: Common barriers to cancer drug access and its administration can be eliminated using regional educational resources to build oncologic workforce capacity, private sector healthcare facilities for infrastructure support and pharmaceutical consortiums to procure low-cost cancer medicines. By leveraging a matrix of global, regional and local stakeholders, the prevailing status quo of very limited access to chemotherapy for women's cancers was creatively disrupted in DRC, Africa's largest fragile, conflict and violence-affected country.

RESUMEN

BACKGROUND: Breast cancer is a leading cause of cancer-related morbidity and mortality in sub-Saharan Africa, a global region where opportunities for breast care of any type are extremely limited due to insufficient infrastructure, a paucity of clinical services and vast shortages of trained human resources. METHODS: A team of Zambian and US gynaecologic and breast oncology experts and nurse-specialists made multiple visits (each lasting 5 working days) to the Democratic Republic of the Congo (DRC), over a 2-year period. During each of five week-long site visits, hands-on training of local Congolese health providers was conducted during which time they were taught clinical breast exam (CBE), breast and axillary ultrasound, ultrasound-guided core needle biopsy/fine needle aspiration (FNA) and breast surgery. Simultaneous with the training exercises, a new breast care clinic was established and operationalised, and existing surgical theatres were upgraded. All activities were implemented in a private sector health care facility - Biamba Marie Mutombo Hospital - in the capital city of Kinshasa. RESULTS: From April 2017 to August 2020, a total of 5,211 women were identified as having breast abnormalities on CBE. Ages ranged from 26 to 86 years; median age: 42.0 (±14.1) years. Ultrasound abnormalities were noted in 1,420 (27%) clients, of which 516 (36%) met the criteria (indeterminate cystic lesion, solid or suspicious masses) for ultrasound-guided core needle biopsy or FNA. Pathology reports were available for 368 (71%) of the 516 clients who underwent biopsy, of which 164 were malignant and 204 benign. The majority (88%) of the cancers were advanced (TNM stages 3 and 4). Surgical procedures consisted of 183 lumpectomies, 58 modified radical mastectomies and 45 axillary lymph node dissections. Clinical competency for diagnostic and surgical procedures was reached early in the course of the training programme. CONCLUSION: By integrating onsite training with simultaneous investments in clinical service and infrastructure development, the barriers to breast cancer diagnosis and treatment were disrupted and a modern breast care service platform was established in a private sector health care facility in the DRC.

RESUMEN

OBJECTIVES: Low physician density, undercapacitated laboratory infrastructures, and limited resources are major limitations to the development and implementation of widely accessible cervical cancer prevention programs in sub-Saharan Africa. MATERIALS AND METHODS: We developed a system operated by nonphysician health providers that used widely available and affordable communication technology to create locally adaptable and sustainable public sector cervical cancer prevention program in Zambia, one of the world's poorest countries. RESULTS: Nurses were trained to perform visual inspection with acetic acid aided by digital cervicography using predefined criteria. Electronic digital images (cervigrams) were reviewed with patients, and distance consultation was sought as necessary. Same-visit cryotherapy or referral for further evaluation by a gynecologist was offered. The Zambian system of "electronic cervical cancer control" bypasses many of the historic barriers to the delivery of preventive health care to women in low-resource environments while facilitating monitoring, evaluation, and continued education of primary health care providers, patient education, and medical records documentation. CONCLUSIONS: The electronic cervical cancer control system uses appropriate technology to bridge the gap between screening and diagnosis, thereby facilitating the conduct of "screen-and-treat" programs. The inherent flexibility of the system lends itself to the integration with future infrastructures using rapid molecular human papillomavirus-based screening approaches and wireless telemedicine communications.

RESUMEN

Until African Americans make a conscious decision to gain control of the social and economic context in which they live, and assume primary responsibility for their health, the reproductive disparities and associated deaths experienced by African-American women will persist. There is truly a need for continued clinical, epidemiologic, and molecular investigations into the problems. Ultimately, however, the permanent elimination of reproductive health disparities will require a social movement, led by members of the target population, informed by the findings of evidenced-based medicine, and fueled by a desire to raise the standard of living of the African-American community. As this occurs, all women will benefit.

RESUMEN

BACKGROUND: Cervical cancer screening efforts linked to HIV/AIDS care programs are being expanded across sub-Saharan Africa. Evidence on the age distribution and determinants of invasive cervical cancer (ICC) cases detected in such programs is limited. METHODS: We analyzed program operations data from the Cervical Cancer Prevention Program in Zambia, the largest public sector programs of its kind in sub-Saharan Africa. We examined age distribution patterns by HIV serostatus of histologically confirmed ICC cases and used multivariable logistic regression to evaluate independent risk factors for ICC among younger (≤35 years) and older (>35 years) women. RESULTS: Between January 2006 and April 2010, of 48,626 women undergoing screening, 571 (1.2%) were diagnosed with ICC, including 262 (46%) HIV seropositive (median age: 35 years), 131 (23%) HIV seronegative (median age: 40 years), and 178 (31%) of unknown HIV serostatus (median age: 38 years). Among younger (≤35 years) women, being HIV seropositive was associated with a 4-fold higher risk of ICC [adjusted odds ratio = 4.1 (95% confidence interval: 2.8, 5.9)] than being HIV seronegative. The risk of ICC increased with increasing age among HIV-seronegative women and women with unknown HIV serostatus, but among HIV-seropositive women, the risk peaked around age 35 and nonsignificantly declined with increasing ages. Other factors related to ICC included being married (vs. being unmarried/widowed) in both younger and older women, and with having 2+ (vs. ≤1) lifetime sexual partners among younger women. CONCLUSIONS: HIV infection seems to have increased the risk of cervical cancer among younger women in Zambia, pointing to the urgent need for expanding targeted screening interventions.

RESUMEN

BACKGROUND: Very few efforts have been undertaken to scale-up low-cost approaches to cervical cancer prevention in low-resource countries. METHODS: In a public sector cervical cancer prevention program in Zambia, nurses provided visual-inspection with acetic acid (VIA) and cryotherapy in clinics co-housed with HIV/AIDS programs, and referred women with complex lesions for histopathologic evaluation. Low-cost technological adaptations were deployed for improving VIA detection, facilitating expert physician opinion, and ensuring quality assurance. Key process and outcome indicators were derived by analyzing electronic medical records to evaluate program expansion efforts. FINDINGS: Between 2006-2013, screening services were expanded from 2 to 12 clinics in Lusaka, the most-populous province in Zambia, through which 102,942 women were screened. The majority (71.7%) were in the target age-range of 25-49 years; 28% were HIV-positive. Out of 101,867 with evaluable data, 20,419 (20%) were VIA positive, of whom 11,508 (56.4%) were treated with cryotherapy, and 8,911 (43.6%) were referred for histopathologic evaluation. Most women (87%, 86,301 of 98,961 evaluable) received same-day services (including 5% undergoing same-visit cryotherapy and 82% screening VIA-negative). The proportion of women with cervical intraepithelial neoplasia grade 2 and worse (CIN2+) among those referred for histopathologic evaluation was 44.1% (1,735/3,938 with histopathology results). Detection rates for CIN2+ and invasive cervical cancer were 17 and 7 per 1,000 women screened, respectively. Women with HIV were more likely to screen positive, to be referred for histopathologic evaluation, and to have cervical precancer and cancer than HIV-negative women. INTERPRETATION: We creatively disrupted the 'no screening' status quo prevailing in Zambia and addressed the heavy burden of cervical disease among previously unscreened women by establishing and scaling-up public-sector screening and treatment services at a population level. Key determinants for successful expansion included leveraging HIV/AIDS program investments, and context-specific information technology applications for quality assurance and filling human resource gaps.

RESUMEN

Although there is a growing literature on the clinical performance of visual inspection with acetic acid in HIV-infected women, to the best of our knowledge, none have studied visual inspection with acetic acid enhanced by digital cervicography. We estimated clinical performance of cervicography and cytology to detect cervical intraepithelial neoplasia grade 2 or worse. Sensitivity and specificity of cervicography were 84% [95% confidence interval (CI): 72 to 91) and 58% (95% CI: 52 to 64). At the high-grade squamous intraepithelial lesion or worse cutoff for cytology, sensitivity and specificity were 61% (95% CI: 48 to 72) and 58% (95% CI: 52 to 64). In our study, cervicography seems to be as good as cytology in HIV-infected women.

RESUMEN

BACKGROUND: In the absence of stand-alone infrastructures for delivering cervical cancer screening services, efforts are underway in sub-Saharan Africa to dovetail screening with ongoing vertical health initiatives like HIV/AIDS care programs. Yet, evidence demonstrating the utilization of cervical cancer prevention services in such integrated programs by women of the general population is lacking. METHODS: We analyzed program operations data from the Cervical Cancer Prevention Program in Zambia (CCPPZ), the largest public sector programs of its kind in sub-Saharan Africa. We evaluated patterns of utilization of screening services by HIV serostatus, examined contemporaneous trends in screening outcomes, and used multivariable modeling to identify factors associated with screening test positivity. RESULTS: Between January 2006 and April 2011, CCPPZ services were utilized by 56,247 women who underwent cervical cancer screening with visual inspection with acetic acid (VIA), aided by digital cervicography. The proportion of women accessing these services who were HIV-seropositive declined from 54% to 23% between 2006-2010, which coincided with increasing proportions of HIV-seronegative women (from 22% to 38%) and women whose HIV serostatus was unknown (from 24% to 39%) (all p-for trend<0.001). The rates of VIA screening positivity declined from 47% to 17% during the same period (p-for trend <0.001), and this decline was consistent across all HIV serostatus categories. After adjusting for demographic and sexual/reproductive factors, HIV-seropositive women were more than twice as likely (Odds ratio 2.62, 95% CI 2.49, 2.76) to screen VIA-positive than HIV-seronegative women. CONCLUSIONS: This is the first 'real world' demonstration in a public sector implementation program in a sub-Saharan African setting that with successful program scale-up efforts, nurse-led cervical cancer screening programs targeting women with HIV can expand and serve all women, regardless of HIV serostatus.
