Patients will undergo collection of tumor at the time of tumor resection and after confirmation of tumor progression and will have blood samples drawn pre-surgery and during standard of care follow-up visits. Patients will then be provided with a specialized tumor board recommendations for personalized treatment options for up to 4 medications based on the specimen analysis results within 35 days of surgery. Patients may then elect to initiate recommended therapy within 42 days of surgery.
Other: specialized tumor board recommendation
feasibility of a specialized tumor board to come up with treatment recommendations no later than 35 days from surgery.
Other Name: standard of care therapy
- Number of Participants Who Received Treatment Recommendations Within 35 Days of Surgery [ Time Frame: 35 days from surgery to making genomic informed treatment recommendation ]To demonstrate feasibility, we would want the treatment recommendation to be fully complete within 35 calendar days in at least 85% of patients for which sufficient RNA and DNA is available.
- Number of Patients Who Chose to Pursue Treatment [ Time Frame: Within 35 days from surgery to making genomic informed treatment recommendation ]Number of patients who chose to pursue treatment based on these genomics-informed treatment recommendations
- Successful Generation of Patient-derived Xenograft (PDX) Genomic Models [ Time Frame: Within 12 months after tissue collection ]Number of patient-derived xenograft (PDX) models successfully derived from patient tumor samples.
- Number of Participants Reaching 12 Months Progression Free Survival [ Time Frame: 12 month progression free survival ]Treatment efficacy derived from specialized Tumor Board suggestion, defined by 12 month progression free survival.
Biospecimen Retention: Samples With DNA
Surgery is done and a "core" specimen (from the enhancing component of tumor) and one or more tissue biopsies of the surrounding "rim" are obtained and processed for shipment to TGen for NGS and transcriptome profiling.
Blood is obtained prior to and 24 hours following surgery for assessment of any circulating tumor DNA in blood.
Blood for circulating tumor DNA is collected every 28 days (+/- 7 days).
Whole blood samples will be immediately sent to Ashion for extraction of DNA. Isolated DNA will be quantitated by spectrophotometry, and the distribution of molecular weights in the preparations will be visualized by gel electrophoresis. Blood derived DNA samples will be aliquoted and kept at Ashion at -20 degrees Celsius until use in molecular studies
