Assessment of Preoperative Endometrial Histopathological Sampling as a Predictor of Final Surgical Pathology in Endometrial Cancer

Abstract Objective To evaluate the agreement between the histopathological diagnoses of preoperative endometrial samples and surgical specimens and correlate the agreement between the diagnoses with the impact on surgical management and the survival of patients with endometrial adenocarcinomas. Methods Sixty-two patients treated for endometrial cancer at a university hospital from 2002 to 2011 were retrospectively evaluated. The histopathological findings of preoperative endometrial samples and of surgical specimens were analyzed. The patients were subjected to hysterectomy as well as adjuvant treatment, if necessary, and clinical follow-up, according to the institutional protocol. Lesions were classified as endometrioid tumor (type 1) grades 1, 2, or 3 or non-endometrioid carcinoma (type 2). Results The agreement between the histopathological diagnoses based on preoperative endometrial samples and surgical specimens was fair (Kappa: 0.40; p < 0.001). However, the agreement was very significant for tumor type and grade, in which a higher concordance occurred at a higher grade. The percentage of patients with lymph nodes affected was 19.2%. Although most patients presenting with disease remission or cure were in the early stages (90.5%), there were no significant differences between those patients who had a misdiagnosis (11/16; 68.8%) and those who had a correct diagnosis (25/33; 75.8%) based on preoperative endometrial sampling (p = 0.605). Conclusion Our findings corroborate the literature and confirm the under staging of preoperative endometrial samples based on histopathological assessment, especially for lower grade endometrial tumors. We suggest that the preoperative diagnosis should be complemented with other methods to better plan the surgical management strategy.

Cervical Cancer Outcomes in Mozambique: Impact of an International Gynecologic Oncology Training Program

PURPOSE Cervical cancer is the most common cancer among women in Mozambique and is a major health burden. Surgery for cervical cancer is currently performed at only one hospital in the country, Maputo Central Hospital. Before 2020, there were no gynecologists in Mozambique trained to care for women with cervical cancer. In 2017, the International Gynecologic Cancer Society (IGCS) started a gynecologic oncology training program in Mozambique, and in 2020, the first three fellows graduated from this program. The main objective of this study was to report the outcomes of patients with cervical cancer who were treated surgically by the three newly trained Mozambican gynecologic oncologists. METHODS We performed a retrospective chart review of women diagnosed with cervical cancer who underwent surgical treatment by the Mozambican gynecologic oncologists between November 2020 and October 2022. The outcome of interest was survival at 2 years. RESULTS Thirty-three patients underwent radical hysterectomy with pelvic lymphadenectomy for cervical cancer treatment. The median age at diagnosis was 43 years. After surgery, 15 patients (45%) were dispositioned to surveillance and 18 (55%) were referred for adjuvant treatment with radiotherapy and/or chemotherapy. All patients had follow-up data available, with a median follow-up time of 19 months (range, 0.2 to 37.5). Only one patient died, and the overall survival is 95.7% (95% CI, 87.7% to 100%) at 12.7 months. CONCLUSION The IGCS program has provided training to physicians at Maputo Central Hospital, resulting in surgery for cervical cancer being available to patients in Mozambique. This is an important step in the global elimination of cervical cancer.

Exploring cervical cancer mortality in Brazil: an ecological study on socioeconomic and healthcare factors

To evaluate the correlation between socioeconomic and healthcare factors and cervical cancer mortality rates, as well as the accessibility to prevention and treatment across Brazilian states and macroregions. The aim is to highlight the multifaceted challenge of addressing cervical cancer mortality, particularly in low-and middle-income countries. This ecological study analyzed public data from the Brazilian National Institute of Cancer (INCA), the National Institute of Geography and Statistics (IBGE), and the Brazilian Ministry of Health. Data were collected on indicators such as the Human Development Index (HDI), physician density, average household income, human papillomavirus (HPV) vaccine coverage, Pap smear screening rates, radiotherapy machine density, and non-White population rates by state and macroregion across Brazil. Spearman's rank correlation test and simple linear regression analysis were employed. Cervical cancer mortality rates are statistically lower in women with health insurance, positive self-perception of health, located in states with a higher HDI, higher per capita household income, greater density of physicians, and higher availability of radiotherapy machines. In contrast, mortality rates proportionally increase according to poverty levels, as expected, and rates of non-White population. Considering public health, HDI scores significantly affected Pap smear test coverage, the number of radiotherapy machines, and HPV vaccine uptake. The North and the Southeast regions have, respectively, the lowest and the highest socioeconomic indicators, proportional to their mortality rates. No significant correlation was found between mortality rates and HPV vaccine or Pap smear coverage. Cervical cancer mortality in Brazil is significantly influenced by socioeconomic and healthcare disparities. This study provides a data-driven basis for public health strategies that address both medical and social determinants of health.

LACC Trial: Final Analysis on Overall Survival Comparing Open Versus Minimally Invasive Radical Hysterectomy for Early-Stage Cervical Cancer

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported. The aim of this study was to compare overall survival between open and minimally invasive radical hysterectomy with participants followed for 4.5 years. The primary objective was to evaluate whether minimally invasive surgery was noninferior in disease-free survival (DFS) to abdominal radical hysterectomy. Secondary outcomes included overall survival. Sample size was based on DFS of 90% at 4.5 years and 7.2% noninferiority margin for minimally invasive surgery. A total of 631 patients were enrolled: 319 assigned to minimally invasive and 312 to open surgery. Of these, 289 (90.6%) patients underwent minimally invasive surgery and 274 (87.8%) patients open surgery. At 4.5 years, DFS was 85.0% in the minimally invasive group and 96% in the open group (difference of –11.1; 95% CI, –15.8 to –6.3; P = .95 for noninferiority). Minimally invasive surgery was associated with lower rate of DFS compared with open surgery (hazard ratio [HR], 3.91 [95% CI, 2.02 to 7.58]; P < .001). Rate of overall survival at 4.5 years was 90.6% versus 96.2% for the minimally invasive and open surgery groups, respectively (HR for death of any cause = 2.71 [95% CI, 1.32 to 5.59]; P = .007). Given higher recurrence rate and worse overall survival with minimally invasive surgery, an open approach should be standard of care.

Adnexal mass: diagnosis and management

Cervical Cancer-Related Knowledge, Attitudes, Practices and Self-Screening Acceptance Among Patients, Employees, and Social Media Followers of Major Brazilian Hospital

Background Brazil has a high burden of cervical cancer, even though it is preventable, traceable and treatable. Hence, this study evaluated levels of knowledge, attitudes and practices (KAP) related to cervical cancer screening and diagnosis and acceptance of self-screening techniques among women aged 24 and greater. Methods A cross-sectional KAP survey was administered to n = 4206 women and spanned questions relating to cervical cancer, HPV, speculum, Pap test and colposcopy. Questionnaire was disseminated through a major hospital’s social media platforms, intranet and gynecologic-oncology clinics. Logistic regressions evaluated associations between sociodemographic characteristics and knowledge, attitudes, and preventative behaviors against cervical cancer. Participants indicated willingness to try DNA-HPV self-sampling and cervix self-visualization (self-colposcopy). Findings Participants were mostly white individuals (70.5%) with higher education and from social classes A and B. They demonstrated superior levels of KAP than described in the literature, with over 57.8% having answered 80+% of questions correctly. KAP scores were predicted by social class, educational attainment, race, history of premalignant cervical lesions and geographic location. About 80% and 63% would be willing to try DNA-HPV self-sampling and cervix self-visualization, respectively. Interest in self-screening was associated with adequate attitude (OR = 1.85) and inadequate practice (OR = .83). Interpretation Adequate KAP are fundamental for the successful implementation of a self-screening program. Participants were interested in methods that provide them with greater autonomy, control and practicality. Self-screening could address barriers for under-screened women such as shame, discomfort, distance from clinics and competing commitments, enabling Brazil to reach the WHO’s cervical cancer elimination goals. It could also decrease excess medical intervention in over-screened populations by promoting shared decision-making.

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.

Surgery in Ovarian Cancer—Brazilian Society of Surgical Oncology Consensus

ABSTRACTSurgical management in epithelial ovarian cancer (EOC) has a significant impact on overall survival (OS) and progression‐free survival (PFS). The Brazilian Society of Surgical Oncology (BSSO) supported an expert‐led task force for consensus: the best EOC surgery is provided by experienced and specialized trained surgeons in cancer centers. Laparoscopic or radiological staging can predict the possibility of complete cytoreduction (CC0) and help to reduce unnecessary laparotomies. Carcinomatosis and nodal extension should be evaluated at imaging. Multidisciplinary input is essential for determining the need for the selection of patients for surgery and adjuvant chemotherapy in patients with EOC. The BSSO proposes quality assurance criteria and the need for national consensus. Genetic counseling was deemed mandatory for all patients with EOC. This consensus states the final recommendations from BSSO for the management of EOC.

Laparoscopic Approach to Cervical Cancer

The goal of this clinical research study is to compare the long-term outcomes of different surgical methods for the treatment of cervical cancer. The long-term outcome of a total abdominal radical hysterectomy (TARH) will be compared against laparoscopy. In this study, the laparoscopy will be done with or without robotic technology.
