Special Issue Information

Dear Colleagues,

This Special Issue is the second edition of the Special Issue "Unmet Need for Evidence on the Possible Role of Neoadjuvant Chemotherapy in Gynecologic Malignant Disease, Volume II" (https://www.mdpi.com/journal/cancers/special_issues/Gynaecologic_Malignant_Disease).

Neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) can be an alternative approach to primary cytoreductive surgery in ovarian cancer. Multiple European and Asian randomized controlled trials have examined the perioperative and oncological outcomes of NACT followed by IDS for ovarian cancer, and recent meta-analyses of these trials concluded that NACT–IDS has a survival effect comparable to that of primary debulking surgery with lower perioperative morbidity and mortality. Owing to the results of recent level I evidence, the use of NACT has gradually increased in recent years. Nevertheless, the optimal NACT regimen, as well as the optimal NACT cycle course, remain undetermined.

Unlike the positive effects of NACT on the outcomes of ovarian cancer, the role of NACT in cervical cancer appears to be limited. However, the number of randomized controlled trials to assess the possible role of NACT in cervical cancer is still limited, and further studies are warranted.

As for endometrial cancer, clinical studies that examine the role of NACT in advanced endometrial cancer are scant. To the best of our knowledge, no randomized controlled study on this matter has been conducted. In this Special Issue, we focus on the unmet need for evidence on the effects of NACT on gynecological malignant diseases.

This Special Issue focuses on unresolved clinical questions regarding the possible role of NACT in gynecologic malignancies, i.e., the optimal NACT regimen and cycle course in ovarian cancer, the possible effect of NACT on cervical cancer, and the role of NACT in endometrial cancer.

Original research articles and reviews are both welcome. We look forward to your response.

Randomized clinical trials assessing the efficacy of neoadjuvant chemotherapy (NACT) for advanced epithelial ovarian cancer have predominantly included women with high-grade serous carcinomas. The response rate and oncological outcomes of NACT for malignant ovarian germ cell tumors (MOGCT) are poorly understood. This study aimed to examine the effects of NACT on women with MOGCT by conducting a systematic review of four public search engines. Fifteen studies were identified, and a further descriptive analysis was performed for 10 original articles. In those studies, most women were treated with a bleomycin, etoposide, and cisplatin regimen, and one to three cycles were used in most studies. Four studies comparing NACT and primary debulking surgery showed similar complete response rates (n = 2; pooled odds ratio [OR] 0.90, 95% confidence interval [CI] 0.15–5.27), comparable overall survival (n = 3; 87.0–100% versus 70.0–100%), disease-free survival (n = 3; 87.0–100% versus 70.0–100%), recurrence rate (n = 1; OR 3.50, 95%CI 0.38–32.50), and adverse events rate from chemotherapy between the groups. In conclusion, NACT may be considered for the management of MOGCT; however, possible candidates for NACT use and an ideal number of NACT cycles remain unknown. Further studies are warranted to validate the efficacy of NACT in advanced MOGCT patients. Full article
