Cervical adenocarcinoma is associated with a poor prognosis, which may be caused by the infiltrative growth pattern and metastasis of tumor cells. There is a lack of consensus on hysterectomy after radiotherapy for the improvement of selected cases. The present study aimed to assess the oncological outcome of post-radiotherapy hysterectomy in females with cervical adenocarcinoma. A total of 39 females with cervical adenocarcinoma at stages IB1 to IIIB, managed primarily with radiotherapy with complete response, and underwent extrafascial hysterectomy as consolidation therapy between 1988 to 2015 were studied. Surgery complications and residual disease were evaluated. A comparison group was constructed, comprising 41 females with cervical adenocarcinoma managed with exclusive radiotherapy or chemoradiotherapy demonstrating complete response, without surgery. Descriptive and survival analysis was performed. The groups were comparable in terms of age, cancer stage, radiotherapy (dose and duration) and follow-up, although 67% of hysterectomies were performed prior to 2002 and 46% of the radiotherapy group received chemoradiation. Late complications were similar. There were nine recurrences (23%) in the case series and 10 recurrences (24%) in the radiotherapy group. Residual disease was detected in 56% (22/39) of uterine specimens, of which 12 were up to 10 mm. Residual disease was associated with recurrence (31% vs. 6%, P=0.028). The overall survival rate was 75% for the case series vs. 88% for the radiotherapy group (P=0.579), and the disease-free survival rate was 79-80% for both. Removal of residual disease by hysterectomy did not improve the overall survival rate (P=0.283) and disease-free survival rate (P=0.072). Post-radiotherapy hysterectomy in cervical adenocarcinoma is a feasible procedure with acceptable complications, however, it did not bring relevant benefits in recurrences, disease-free survival, and overall survival rates.

In 2018, WHO called for global action to eliminate cervical cancer. The complexity of the processes involved in terms of prevention is often underestimated. Low‐ and middle‐income countries do not have a robust healthcare framework to ensure high‐quality programs. The present article discusses how fragile healthcare systems are barriers to eliminating cervical cancer, and also reports the experience of a Brazilian prevention program. The article considers how cervical cancer can be interpreted as an indicator of inequality: how women's attitudes and access to care determine an early or late diagnosis, and how strategies combining vaccine and DNA‐HPV tests are crucial. New vaccine schemes, the critical analysis of local data, strengthening communication, managing sentinel events, and integrating vaccination and screening data for the health information system are some of the key activities to sustainable improvement in both access and quality of care. There is an urgent need to expand access and quality of care of cervical cancer vaccine and screening in low‐ and middle‐income countries. [ABSTRACT FROM AUTHOR]

Objective: To detect factors related to overtreatment with the "Screen-and-treat" approach (S&T) in women with suspicious cervical precancerous lesions.Study Design: A retrospective observational study of 524 women with high-grade squamous intraepithelial lesions (HSIL) or more severe (HSIL+) in cytology, treated by the Large Loop Excision of the Transformation Zone (LLETZ): 161 without a previous biopsy (S&T group) and 363 with a previous biopsy (biopsy group) from January 2017 to July 2020. The main outcome was a diagnosis of LLETZ: negative (negative or low-grade squamous intraepithlelial lesion LSIL) or HSIL+. A negative diagnosis was interpreted as "overtreatment." Results were analyzed as a function of the S&T approach (whether previous biopsy or not). Variables were obtained from medical records, and were compared with Chi-square or Fisher's exact test (p, p-value), to estimate the chances of a logistic regression analysis (Odds Ratio, OR, or admitting a Confidence Interval (CI) of 95 %).Results: No differences were observed in groups regarding menopausal status, smoking, hormonal contraceptive use, colposcopy findings, LLETZ diagnosis, and recurrence. Comparing biopsy vs S&T groups, the frequency of women over 40 years was 28.4 % vs 39.7 % (p = 0.011), and transformation zone type 3 was 12.2 vs 26.8 % (p < 0.001), respectively. In women managed by S&T, when compared to a LLETZ diagnosis, an HSIL+ result was more frequent in women presenting with TZ 1 (93.1 % TZ1 vs 78.5 % TZ2 vs 73.8 % TZ3, p = 0.008) and in women with abnormal colposcopy (92.9 % abnormal vs 38.1 % negative, p < 0.001). Multiple regression analysis found that women with negative colposcopic findings presented a higher risk for negative LLETZ diagnosis (LSIL/Negative final histology) (18.6; 6.18-56.02).Conclusions: No difference was observed in the LLETZ diagnosis in women who did or did not use the S&T approach: it was adequate for women referred by cytological HSIL along with high-grade colposcopic findings.

Objective: To evaluate the pattern of cervical cancer (CC) diagnosis and outcomes in women under 25. Methods: Thirty‐two women younger than 25 years of age treated between 2001 and 2016 were studied and the year, symptom or cytology before diagnosis, time since sexual debut, age group, histology, and stage were considered. Data were compared with older age groups, and survival analysis was performed using a subset of them. Results: Thirty‐two CC diagnoses (1.5% of all cases) exhibited a positive linear trend (P = 0.075). Driven by cytology, 18 were asymptomatic and 14 were symptomatic (with vaginal bleeding in 11). The mean time since sexual debut was 6.9 years. Advanced stage (44% vs 29%) and adenosquamous histology (12.5% vs 1.7%–5.0%) were higher in younger women. Five‐year overall survival rate was 76%, better for squamous cell carcinoma (SCC) (86% vs 43% for other histologies; P = 0.018). There were seven deaths, all within 15 months of diagnosis. Age groups of less than 25 years (53%) and 25–29 years (48.5%) had similar proportions of Stage IA1. Conclusion: The rate of CC‐diagnosed women under 25 years was 1.5% of all cases, exhibiting more advanced stage and non‐SCC histology. For asymptomatic women, cytology allowed the diagnosis at an early stage. Being symptomatic and non‐SCC was associated with a higher proportion of advanced stages and poor survival. Synopsis: Cervical cancer cases in women under 25 years of age were 1.5%, exhibiting more advanced staging cases and a higher proportion of nonsquamous cell carcinoma histology.
