e14730 Background: To assess the clinical benefit of treatment in advanced and refractory solid tumors utilizing evidence-guided molecular profiling (MP) of tumors in routine clinical practice. Methods: This retrospective observational study was conducted on patients with advanced or refractory metastatic solid tumors, whose tumor biopsy samples were referred for profiling using a multi-platform tumor profiling service (Caris Molecular Intelligence) between January 2014 and April 2017. Specific testing was performed per physician’s request and included a combination of next-generation sequencing (NGS), protein expression (IHC), gene amplification (CISH or FISH), and/or RNA fusion analysis. Results: Data of twenty five patients with solid tumors was analyzed (median age of 58 years, range 25-82 years). Patients had received a median of 2 prior lines of therapy (range 0-6). In evaluable patients, 1 (4%) patient had a complete response, 10 (46%) patients had a partial response, 5 (23%) had stable disease and 6 (27%) had progressive disease, giving a disease control rate of 73%. The majority of patients received chemotherapy (CT) alone (13; 56%). Five patients received CT combined with targeted therapy (TT), 2 received TT alone, 2 received TT combined with hormone therapy (HT), 2 have received immunotherapy and 1 received HT alone. Two patients were not evaluable for response. In responding patients, median duration of response was 7 months (3-18 months). Conclusions: The result of this study show that treatment based on Broad tumor profiling in a select group of advanced and refractory solid tumors was associated with a high disease control rate.
