Intervention model: SINGLE_GROUP
Intervention model description: Two cohorts: unresectable and resectable
Primary purpose: TREATMENT

Brief summary: 1. To evaluate the efficacy of neoadjuvant chemotherapy SLOG in localized pancreatic cancer
2. To evaluate the safety profile in patients with pancreatic cancer who receive neoadjuvant SLOG
3. To collect tumor tissue and peripheral blood samples from the patients for a comprehensive biomarker evaluation

Detailed description: The role of neoadjuvant treatment in pancreatic adenocarcinoma is still under debate due to a relative lack of robust data compared with other gastrointestinal cancers. According to 2020 NCCN guidelines, neoadjuvant is now the accepted approach for borderline resectable (BR) disease, while upfront surgery is still the recommendation for resectable disease except in cases with high risk features. Another important advantage of treatment with neoadjuvant treatment is an increase in the proportion of patients who receive chemotherapy. Traditionally, only patients with a good performance status and a good recovery after surgery are treated with adjuvant chemotherapy. About 45% of patients do not receive adjuvant chemotherapy after resection due to poor performance status, postoperative morbidity, or early progression of disease. A small cohort study using total neoadjuvant FOLFIRINOX for borderline resectable pancreatic cancer yielded a promising result but the tolerability of FOLFIRINOX limited the use of this regimen in Asian population. In previous T1211 clinical trial, the SLOG regimen showed comparable efficacy with a better safety profile in metastatic pancreatic cancer. This phase II trial will evaluate the feasibility of SLOG regimen in patients with localized pancreatic cancer.
