Presented are the first two reported cases of patients who underwent ovarian tissue vitrification in the Philippines. One case is a 22 year old nulligravid diagnosed with invasive Ductal Carcinoma Stage IIIA of the right breast (status post Modified Radical Mastectomy), and advised to undergo systemic chemotherapy with Doxorubicin and Cyclophosphamide. The other case is a 34 year old primary infertility patient, diagnosed with Non-keratinizing Squamous Cell Carcinoma of the Cervix. Stage 1B2, and was advised neoadjuvant platinum-based chemotherapy with concurrent radiotherapy and brachytherapy. Both women are desirous of pregnancy and so underwent ovarian tissue cryopreservation prior to medical management of their condition, to preserve future reproduction.
