Summary
In-hospital and 30-day mortality after pancreatectomy are comparable nationally. Post-60 day mortality risk remains constant, highlighting the need to reduce perioperative deaths for improved survival.
Area of Science:
- Oncology
- Surgical Outcomes
- Public Health
Background:
- Pancreatectomy outcomes are evaluated using distinct measures like in-hospital and 30-day mortality.
- National data can enhance precision in evaluating published pancreatectomy outcomes.
Purpose of the Study:
- To compare in-hospital and 30-day mortality rates nationally after pancreatectomy for cancer.
- To analyze mortality trends and risk factors within the first 60 days and up to 2 years post-resection.
Main Methods:
- Utilized linked SEER-Medicare databases (1991-2002) for patients undergoing pancreatic cancer resection.
- Analyzed mortality trends using trend tests and assessed patient characteristics via univariate analysis.
Main Results:
- Identified 1,847 resected patients; 8.1% experienced in-hospital mortality, with 79% occurring within 30 days.
- Mortality risk significantly decreased within the first 60 days (P < 0.0001) but remained constant from 60 days to 2 years (P = 0.8533).
- Patients dying within 60 days were more likely to have experienced complications (41.1% vs. 17.0%, P < 0.0001).
Conclusions:
- In-hospital and 30-day mortality are similar nationally, making them acceptable for comparing pancreatectomy outcomes.
- Mortality risk stabilizes after 60 days, indicating a continuous risk beyond early complications or late cancer progression.
- Reducing perioperative mortality within the critical 60-day interval is crucial for improving overall patient survival after pancreatectomy.
