Special Issue Information

Dear Colleagues,

There are significant geographical variations in the incidence of gynecological cancers worldwide. Patient outcomes depend on understanding tumor biology, prevention and screening, timely interventions and appropriate treatment. Additionally, epidemiological studies can help policy makers direct precious resources and shape healthcare systems.

We would therefore like to invite authors to contribute to this Special Issue, which focuses on new developments, such as the incidence and prevalence of women’s cancers, lifestyle factors, investigative pathways, genetic testing, new staging systems, quality of life, adjunctive treatment algorithms and the impact of low resources on patient survival.

Background: The prognosis for recurrent ovarian cancer is poor, but a small percentage of patients can be cured. The aim of this study was to clarify the criteria for being cured and the characteristics of cured cases. Methods: Ovarian cancer cases at 2 university hospitals and 8 community hospitals were analyzed to identify patients who were considered cured after complete remission (CR) following recurrence. Analyses of the tumors were performed and included BRCA1/2 mutation analysis. Results: Of the 157 cases of recurrence, 21 (13%) showed no evidence of disease (NED). NED cases had a lower rate of ascites at the initial diagnosis, longer disease-free survival, a higher rate of solitary lesions, and a higher rate of secondary debulking surgery. All CR cases except for one showed no further recurrence when DFS reached 4 years, which was considered a criterion for being cured. The case of relapse occurred after long-term treatment with bevacizumab. Furthermore, 19.4% of the CR cases achieved 4-year DFS, which represents 9.3% of the cases of recurrent ovarian cancer and 2.3% of all cases of ovarian cancer. BRCA mutation analysis of the tumor was possible in 17 of the 30 cases of recurrent ovarian cancer that achieved a 4-year DFS. Pathogenic variants of BRCA were found in 5 of the 11 cases of high-grade serous carcinoma. Conclusions: Approximately 10% of patients with recurrent ovarian cancer achieved a 4-year DFS and were mostly cured. The curing of cases not involving high-grade serous carcinoma (HGSC) was unrelated to the presence of pathogenic BRCA variants. Full article

Objective: This study aimed to evaluate the association between the Peritoneal Cancer Index (PCI) and the completeness of cytoreductive surgery (CRS) in patients undergoing surgery for advanced ovarian cancer (AOC). Secondary objectives included identifying a PCI cut-off predictive of incomplete cytoreduction, assessing the relationship between PCI and surgical complexity via the Aletti Surgical Complexity Score (SCS), and exploring disease distribution to better understand ovarian cancer distribution. Methods: A retrospective review of 227 patients undergoing primary or interval debulking surgery for AOC from January 2017 to September 2024 at University Hospitals of Derby and Burton was conducted. PCI was recorded intra-operatively, and procedures were classified using the SCS. ROC analysis identified PCI thresholds for incomplete CRS, logistic regression predicted CRS outcomes, and heat mapping visualised disease distribution. Results: Complete CRS of visible disease (R0) was achieved in 90.75% of patients, while 9.25% had incomplete CRS. Median PCI was significantly higher in incomplete CRS cases (28, IQR 21–32) compared to complete CRS (15, IQR 8–23, p < 0.001). ROC analysis identified a PCI threshold of 25.5 with 71.4% sensitivity and 83.5% specificity for predicting incomplete CRS. PCI > 25.5 increased the odds of incomplete cytoreduction by 12.65 times (p < 0.001). Higher PCI scores correlated with increased surgical complexity, operative time, and blood loss, though complication rates were similar. Heat maps showed stepwise disease distribution from pelvis to upper abdomen. Conclusions: PCI is a reliable predictor of CRS completeness in AOC, with a threshold of >25.5 indicating a high risk of incomplete cytoreduction. The study underscores PCI’s role in surgical planning and calls for multi-centre studies to validate these findings and further examine disease distribution. Full article

Immature teratoma of the ovary is a rare condition primarily affecting young women and constitutes a significant proportion of ovarian cancer cases in adolescents and young adults. It is commonly diagnosed at stage I, though advanced-stage disease is not infrequent. Accurate diagnosis and a fertility-sparing approach are central to the management of this condition, as many affected women retain, or have yet to develop, a desire for childbearing. However, due to the rarity of this disease, management is often guided by retrospective data derived from subanalyses of studies on malignant ovarian germ cell tumors, which can complicate the treatment of these patients once diagnosed. The aim of this review is to summarize the current evidence on immature teratoma of the ovary, considering it as a distinct clinical and pathological entity. Full article
