Unresectable Locally Advanced Pancreatic Cancer
Conditions
Brief summary
The goal of this observational study is to learn about the therapeutic effects of chemoradiotherapy for older adults (age 70-85) with locally advanced pancreatic cancer. The main question it aims to answer is: Does chemoradiotherapy represent an effective and safe treatment for older participants without radical surgery? Participants will sequentially receive combined chemotherapy followed by concurrent chemoradiotherapy and subsequent maintenance therapy.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 1-year survival rate | From the date of first therapy administration to one year later | To observe whether the 1-year survival rate of elderly patients with locally advanced pancreatic cancer treated with sandwich-like chemoradiotherapy modality was comparable to that of the historical data of the general adult population. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| event-free survival throughout the enrolled subject population | From the date of first therapy administration until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months. | Survival time from the start of therapy administration to the date of first documented progression or the date of death |
| the proportion of participants that completed chemoradiotherapy | From the date of first enrollment to the date of completion of follow-up of the last patient, up to 24 months. | — |
| Toxicity and side effects and tolerability assessment | From the date of first therapy administration to within 90 days, up to 24 months | Safety and tolerance will be evaluated by incidence, severity and outcomes of adverse events (AEs) and categorized by severity in accordance with the NCI CTCAE Version 5.0. |
| Objective response rate (ORR) tumor target lesions in the entire subject population all planned courses | From the date of first therapy administration until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months. | ORR is defined as the percentage of patients who achieve complete response (CR) or partial response (PR) based on the Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. |
| Disease control rate (DCR) of tumor target lesions in the entire subject population all planned courses | From date of first therapy administration until the date of first documented progression or date of death from any cause, whichever occurs first, assessed up to 24 months. | DCR is defined as the percentage of patients who achieved CR, PR and stable disease (SD), and will be evaluated based on RECIST 1.1 and the irRECIST criteria. |
| the proportion ofparticipants that completed all planned courses | From the date of first enrollment to the date of completion of follow-up of the last patient, up to 24 months. | — |
