The FOLFIRINOX/FOLFOX Regimens Show Promising Results In PDAC Patients

KEY TAKEAWAYS

  • In two trials (BACAP and GEMCIPANC), patient data were studied to determine the effectiveness of FOLFIRINOX/FOLFOX regimens in PDAC.
  • The patients with FOLFIRINOX/FOLFOX treatments who tested positive for F/FX showed notably longer PFS and OS rates.
  • Those treated with gemcitabine didn’t exhibit significant differences in survival outcomes based on their F/FX test results.

In 2022, researchers introduced the GemciTest, a blood-based RNA signature that predicts the response to gemcitabine-centric initial treatments in pancreatic ductal adenocarcinoma (PDAC) patients (pts). The study’s objective was to evaluate the effectiveness of a complementary blood-based RNA signature (F/FX) to predict the response to FOLFIRINOX/FOLFOX regimens in advanced pancreatic adenocarcinoma.

Researchers conducted discovery and validation phases to validate their findings clinically, involving 164 untreated late-stage PDAC pts (mean age: 68.7 years; age range: 37-88). These pts were administered either gemcitabine or fluoropyrimidine-based treatments. The F/FX test identifies the expression rates of ten specific genes via the real-time PCR procedure.

For those treated with FOLFIRINOX/FOLFOX (n=90), pts who tested positive for F/FX (31.1%) witnessed a notably extended progression-free survival (PFS) and median overall survival (OS). A Pearson correlation coefficient of 0.73 was found between OS and PFS. However, gemcitabine-treated pts (n=74) didn’t exhibit any substantial variance in PFS and OS when comparing positive and negative F/FX results.

The F/FX highlighted the potential benefits of using a blood-based RNA signature as a less invasive method to enhance survival rates and tailor treatment in PDAC pts undergoing FOLFIRINOX/FOLFOX as an initial treatment. Even though these findings are encouraging, a prospective study is necessary to validate them, especially when considering pts with non-resectable locally advanced and metastatic tumors.
