Abstract
BACKGROUND
The overall incidence of gastric cancer is higher in men than women worldwide. However, gastric signet-ring cell carcinoma (GSRC) is more frequently observed in younger female patients.
AIM
To analyze clinicopathological differences between sexes in GSRC, because of the limited evidence regarding association between sex-specific differences and survival.
METHODS
We reviewed medical records for 1431 patients who received treatment for GSRC at the Cancer Hospital, Chinese Academy of Medical Sciences between January 2011 and December 2018 and surveyed reproductive factors. Clinicopathological characteristics were compared between female and male patients. Cox multivariable model was used to compare the mortality risks of GSRC among men, menstrual women, and menopausal women.
RESULTS
Of 1431 patients, 935 patients were male and 496 were female (181 menstrual and 315 menopausal). The 5-year overall survival in male, menstrual female and menopausal female groups was 65.6%, 76.5% and 65%, respectively (P < 0.01). Menstruation was found to be a protective factor (hazard ratio = 0.58, 95% confidence interval: 0.42–0.82).
CONCLUSION
The mortality risk of GSRC in menstrual women was lower than that in men. This study identified the protective effects of female reproductive factors in GSRC.
Core Tip: The overall incidence of gastric cancer is higher in men than in women worldwide. However, gastric signet-ring cell carcinoma (GSRC) is more frequently observed in younger female patients. Only a few studies have focused on sex-specific differences in GSRC. This study proposed clinicopathological differences between sexes to reveal sex disparities in GSRC and confirmed that female reproductive factors provided protective effects, and the mortality risk of menstrual female patients was lower. Investigation of the mechanism of action of female reproductive factors may provide new insight into the treatment of GSRC.
