➔ Metastatic disease “old” Conclusion
• Treatment of pancreatic neoplasms remains a challenge
• We have seen some recent improvements
– Gem + erlotinib, new standard
– Gem + capecitabine ?
– To a less extent : Gem + cisplatin
– Other combination CT ?
• But we urgently need
– Translational research to find new targets
– A better definition of strategy
Always the sameStory ?

➔ Rationale of PARPi against metastatic
pancreatic cancer
23
– 4-7% of metastatic pancreatic cancer patients harbor a germline BRCA1 and/or BRCA2 mutations (gBRCAm)[a,b]
– Olaparib, a PARP inhibitor, has demonstrated clinical benefits in gBRCAmovarian and breast cancers[c,d]
– In subset of phase II olaparib trial, olaparib showed promising efficacy outcome with median PFS of 4.6 months and ORR of 21.7% in patients who previously received gemcitabine (1-8 prior lines of therapy).

in Newly Diagnosed Pancreatic Cancer
Irrespective of Family History
• NCCN Pancreatic Cancer (V3.2019 – released July 2, 2019)
– Germline testing should be considered is recommended for any patient with confirmed
pancreatic cancer using comprehensive gene panels for hereditary cancer syndromes.
Genetic counseling is recommended for patients who test positive for pathogenic
mutation or for patients with a positive family history of cancer
– Tumor/somatic gene profiling is recommended for patients with locally
advanced/metastatic disease who are candidates for anticancer therapy, to identify
uncommon but actionable mutations
• NCCN Genetic/Familial High-Risk Assessment BC/OC (V3.2019 – January 18, 2019)

➔Conclusion
• FOLFIRINOX and gemcitabine plus nab-paclitaxel are standard first-line chemotherapy in mPAC patients
• Gemcitabine alone remains the standard of care for a lot of patients
• Best supportive care remains very important in the management of these patients
• Olaparib is the first targeted agent which has proven the improvements in response rates and progression-free survival in gBRCA-mutant mPAC patients with platinum-sensitivity

Defects of DNA Damage Response Mechanisms
• DNA repair system
– 9% to 10% of patients with PDAC have germline or somatic BRCAmutations
• In total, 24% have defects in DDR (mutations in BRCA1/2, PALB2, ATM, CHK1/2...) and/or show a genomic unstable phenotype with DDR insufficiency

• Accumulation of genetic alterations
• Promotion of genomic instability
