Hypothesis
Does the extent of lymphadenectomy affect local relapse, overall survival, and disease-free survival in radically resected gastric cancer patients?
Conclusion
Extended lymphadenectomy significantly improves overall survival and disease-free survival compared to limited lymphadenectomy in gastric cancer patients.
Supporting Evidence
- Patients with extended lymphadenectomy had a median overall survival of 84.8 months compared to 58.8 months for those with limited lymphadenectomy.
- Local recurrence was significantly lower in patients with more than 25 lymph nodes resected (4.7%) compared to those with less than 25 (23%).
- Median disease-free survival was 59.9 months for extended lymphadenectomy versus 28.8 months for limited lymphadenectomy.
Takeaway
This study found that removing more lymph nodes during gastric cancer surgery can help patients live longer and have fewer relapses.
Methodology
Retrospective analysis of 418 gastric cancer patients categorized by the extent of lymphadenectomy.
Potential Biases
Potential bias due to the non-randomized nature of the study and differences in surgical practices.
Limitations
The study is retrospective and may be affected by selection bias.
Participant Demographics
Median age 68 years, 59.6% male, 40.4% female.
