Spots Global Cancer Trial Database for The Registry of Genetic Alterations of Taiwan Ovarian Cancer

Study Description

Brief Summary: Despite recent progress in chemotherapy and targeted therapy for ovarian cancer, the 5-year survival rate remains around 40% because of rapid development of treatment resistance and recurrence. The sensitivity to platinum agents or BRCA genes mutation has been the prerequisite for improved survival using PARP inhibitors, though only 15-20% ovarian cancer patients harbor BRCA mutations through germline or somatic variants. Bevacizumab can only delayed disease recurrence but failed to improve overall survival. Several approved cancer therapeutics with established safety and toxicity profiles should be assessed in the immediate future based on biomarkers of platinum resistant, BRCA wild type recurrent ovarian cancer. Furthermore, the proportion high grade serous and clear cell adenocarcinoma of ovary cancer in Taiwan increased substantially in recent 10 years. Genetic factors (such as homologous recombination deficiency, mismatch repair genes mutation), environmental factors (such as oral contraceptives, nulliparity/low parity) as well as comorbidity including endometriosis may be associated with the changing pattern and clinical outcomes of ovarian cancer in Taiwan. Next-generation sequencing technology has enabled cancer genome sequencing in screening and searching for new cancer genes in an efficient manner. This massive sequencing technique not only help to identify new altered genes for novel biomarker development, but also reveal gene alterations sensitive or resistant to specific therapies. The specific aims of this project are (1) to systemically explore genomic profiling of Taiwanese primary or platinum-resistant recurrent ovarian cancer focusing on high grade serous and clear cell adenocarcinoma; (2) to collect clinical data regarding comorbidity, survival time and responses to major types of anticancer therapy; and (3) to establish a comprehensive ovarian cancer cohort for additional translational studies. The long-term goals of this study are to help implement personalized therapy, to develop novel therapy, and to improve outcomes of patients with ovarian cancer.

Detailed Description: Development of an integrated database of genetic background from treatment-naïve or platinum-refractory populations, clinical information, and therapeutic outcomes in primary and recurrent ovarian cancer of high grade serous or clear cell adenocarcinoma. 1. To enroll 280 patients who fit the criteria of this study in the enrolled period. 2. To perform large-scale NGS analysis including 440 cancer gene panel and 24 HRD panel for specific populations, to create a map containing important genetic characteristics to help understand the mechanisms of drug resistance, and to find novel treatment strategies. 3. To collect tumor, non-tumor normal tissues and/or blood sample for genetic study (including NGS, whole-exome sequencing, RNA sequencing), proteomic study (including phosphoprotein), human leukocyte antigen testing, neoantigen and biomarker analyses. 4. To record previous therapeutic agents and accompanying treatment response and adverse events
