Abstract:
Objective:To assess the clinicopathological feature and prognosis of gastric cancer associated with pregnancy in Chinese population.
Methods:We collected the clinical features, pathological findings, treatment modalities, the health status of infants and the information of prognosis for ten patients developed gastric cancer associated with pregnancy between 2001 and 2016 in our hospital and the counterpart 12 patients reported in China National Knowledge Internet (CNKI), Wanfang database and China Science and Technology Journal Database.
Results:The most common symptoms were nausea and vomiting (n=14). Melena (n=8), abdominal distension (n=7) and abdominal pain (n=6) were also frequent. When considering the complications, gastrointestinal bleeding (n=9), intestinal obstruction (n=3) and gastric perforation (n=2) were common. The vast majority of pathology showed poorly differentiated tumors, poorly differentiated adenocarcinoma (n=14) and signet ring cell carcinoma (n=7). Only one patient was diagnosed at stage Ⅰ. And 17 patients developed metastatic disease of stage Ⅳ. Peritoneum (n=7) and ovary (n=5) were the most common metastasis sites. Three patients received abortion immediately after diagnosis in the first trimester of pregnancy. For the five patients in the second trimester of pregnancy, pregnancy termination was given to three patients. Caesarean section followed by gastrectomy was performed on three patients who were after the third trimester of gestation. Curative resection and palliative operation were carried out on six and five patients respectively. Combined chemotherapy based on oxaliplatin and fluorouracil was the common treatment for the peri-operative patients. For the metastatic gastric caner, platinum in combination with fluorouracil was recommended in the first line condition, irinotecan or raltitrexed were used in the second line treatment. One-year survival rate was 23.1%, and two-years survival was 15.4%. Three patients after R0 resection were alive without relapse over 18 months.
Conclusions:The poor prognosis of gastric cancer associated with pregnancy may due to the late stage and the poor pathological type. There still lacks data of the appropriate treatment in these patients. It was demonstrated most patients have no chance of tumor resection due to the late stage. For the metastatic patients, platinum in combination with fluorouracil was recommended in the first line treatment. Irinotecan or raltitrexed were considered the choice for the second line treatment.
