Background:
Regarding when to treat gastric cancer and ovarian metastasis (GCOM) and whether to have metastatic resection surgery, there is presently debate on a global scale. The purpose of this research is to examine, in real-world patients with GCOM, the survival rates and efficacy of metastatic vs non-metastasized resection.
Aim:
To investigate the survival time and efficacy of metastatic surgery and neoadjuvant therapy in patients with GCOM.
Methods:
This study retrospectively analyzed the data of 41 GCOM patients admitted to Zhejiang Provincial People's Hospital from June 2009 to July 2023. The diagnosis of all patients was confirmed by pathology. The primary study endpoints included overall survival (OS), ovarian survival, OS after surgery (OSAS), disease-free survival (DFS), differences in efficacy.
Results:
This study had 41 patients in total. The surgical group (n = 27) exhibited significantly longer median OS (mOS) and median overall months (mOM) compared to the nonoperative group (n = 14) (mOS: 23.0 vs 6.9 months, P = 0.015; mOM: 18.3 vs 3.8 months, P = 0.001). However, there were no significant differences observed in mOS, mOM, median OSAS (mOSAS), and median DFS (mDFS) between patients in the surgical resection plus neoadjuvant therapy group (n = 11) and those who surgical resection without neoadjuvant therapy group (n = 16) (mOS: 26.1 months vs 21.8 months, P = 0.189; mOM: 19.8 vs 15.2 months, P = 0.424; mOSAS: 13.9 vs 8.7 months, P = 0.661, mDFS: 5.1 vs 8.2 months, P = 0.589).
Conclusion:
Compared to the non-surgical group, the surgical group's survival duration and efficacy are noticeably longer. The efficacy and survival time of the direct surgery group and the neoadjuvant therapy group did not differ significantly.
