Abstract 2031

Background

We initiated the Nationwide Cancer Genome Screening Project in Japan since February 2014. From October 2015, we have introduced the Next Generation Sequencing to detect cancer genome alterations in advanced pancreatic cancer (aPC), called as the SCRUM-Japan GI-SCREEN.

Methods

This study is ongoing with 20 major cancer centers. Patients with aPC who plan to or receive chemotherapy were eligible. DNA and RNA were extracted from formalin-fixed paraffin embedded (FFPE) tumor samples and were analyzed by the Oncomine Cancer Research Panel (OCP) which allows to detect mutations, copy number variant (CNV) and fusion genes in a CLIA certified CAP accredited lab. The detected genomic variant data were classified according to genetic drivers of cancer, including gain- and loss-of-function or single nucleotide variant based on the Oncomine Knowledgebase.

Results

As of March 31st in 2017, total of 270 aPC patients were enrolled and 209 samples were analyzed. The sequence was successfully performed in 136 tumors (65.1%). The origin of samples included the primary site of 65.4%, metastatic site of 34.6%. The tissue samples were obtained by surgical resection 32.4%, needle biopsy 33.8%, EUS-FNA 27.9%, and other 5.9%. Rate for success sequence of EUS-FNA was 56.7%. The frequently detected mutations (≥ 2%) in 136 samples of which results were available were KRAS (91.9%), TP53 (62.5%), CDKN2A (14.0%), SMAD4 (10.3%), GNAS (4.4%), TET2(4.4%), PIK3CA(3.7%), ATM (2.9%), STK11 (2.9%), BRCA2 (2.2%). Most frequently detected CNVs (≥ 7copies) was MYC (2.9%), and no gene fusion was detected. We will show the clinical outcome based on certain key cancer genome alterations.

Conclusions

This nationwide screening system is efficient to detect rare gene alterations in aPC. This novel knowledge provides an intriguing background to investigate new targeted approaches in these patients and to progress precision medicine.
