Effect of First‐Line Chemotherapy Alone Versus First‐Line Chemotherapy Plus Radiotherapy on Survival in Patients With Locally Advanced Pancreatic Cancer in the <scp>IMRT</scp> Era: A Retrospective Cohort Study

The combination of first-line chemotherapy and IMRT improves the DCR rate (p = 0.038) and was well tolerated. However, first-line chemotherapy plus IMRT had no significant difference in PFS (p = 0.465) and OS (p = 0.156) compared with chemotherapy alone.
