Abstract:

Objective To investigate the clinical characteristics and risk factors of patients with gastric cancer-related stroke (GCS). Methods A total of 42 patients with gastric cancer who were diagnosed in the Fourth Hospital of Hebei Medical University from January 2014 to December 2019 and had new cerebral infarction in the course of diagnosis and treatment were included in GCS group. During the same period, eighty-four gastric cancer patients without new cerebral infarction occurred in the course of diagnosis and treatment were included in the control group. Clinical data and characteristics between groups were compared, and those with significant differences were introduced into the multivariate logistic regression analysis to analyze independent risk factors for new cerebral infarction in gastric cancer patients. Results A total of 42 GCS patients with the mean age of 67.14±8.15 (47-86) years were collected in this study, including 34 males and 8 female. They were pathologically diagnosed as gastric adenocarcinomas. Cerebral infarction occurred 0-985 days after the diagnosis of gastric cancer, with the median onset time of 38 days. Magnetic resonance imaging (MRI) showed that 22 cases (52.4%) had multiple lesions and multiple sites involved in the brain, and 25 cases (59.5%) did not receive targeted treatment for gastric cancer because of cerebral infarction. The proportion of hypertension history, diabetes history, hyperlipidemia history and previous cerebral infarction history in GCS group was significantly higher than that in the control group (P<0.05). The prothrombin time, D-dimer and carbohydrate antigen 199 levels in GCS group were significantly higher than those in the control group, while the hemoglobin level was significantly lower than that in the control group (P<0.05). The proportion of patients with surgical history and chemotherapy history in the GCS group was significantly lower than that in the control group (P<0.05). Multivariate logistic regression analysis showed that a previous history of cerebral infarction was an independent risk factor for cerebral infarction in GCS patients. Conclusion Cerebral infarction is highly prevalent within 1-6 months after the diagnosis of gastric cancer. Conventional risk factors for stroke are also independent risk factors for stroke in gastric cancer patients, so as the history of cerebral infarction. Our findings have a important guiding significance for preventing and reducing the occurrence of GCS.
