Forced degradation is a degradation of new drug substance and drug product at conditions more severe than accelerated conditions. It is required to demonstrate specificity of stability indicating methods and also provides an insight into degradation pathways and degradation products of the drug substance and helps in elucidation of the structure of the degradation products. Forced degradation studies show the chemical behavior of the molecule which in turn helps in the development of formulation and package. In addition, the regulatory guidance is very general and does not explain about the performance of forced degradation studies. Thus, this review discusses the current trends in performance of forced degradation studies by providing a strategy for conducting studies on degradation mechanisms and also describes the analytical methods helpful for development of stability indicating method.

Objective:
To study clinical characters and outcomes in patients of malignant ovarian germ cell tumor (MOGCT) undergoing surgery following neoadjuvant chemotherapy (NACT).
Methods:
Retrospective study of patients undergoing surgery following NACT for MOGCT at our institute. Platinum based chemotherapy was given in all patients in NACT.
Results:
Between March 2013 and February 2023, 30 patients had surgery after NACT.Patient’s median age was 22 years (range, 12 to 35 years) and median follow up 42months (range, 6 to 132 months). Majority had endodermal sinus tumor (n=12), dysgerminoma (n=9) and mixed GCT (n=7). All had either International Federation of Gynecology and Obstetrics (FIGO) stage 3 (n=19) or FIGO stage 4 disease (n=11). Complete response to NACT seen in 5 patients and 23 patients had partial response. Fertility sparing surgery in 18 patients and complete surgery in 12 patients. Suboptimal surgery was seen in 4 patients. Currently, 20 of 30 patients are alive and disease free, 3 lost for follow up and 7 patients had progression after adjuvant therapy. Five patients had mortality—4 with progression and 1 with bleomycin toxicity. Fifteen of 17 eligible patients have resumed menstruation and one had successful pregnancy. Prognostic factors noted in study are stage, optimal surgery and viable tumor in histopathology. Dysgerminoma had better outcome than other histology.
Conclusion
NACT may be a reasonable option in patients with extensive unresectable disease or in whom fertility sparing is not possible or in the poor general condition. Fertility sparing surgery can be attempted post neoadjuvant chemotherapy without adversely affecting prognosis.
