Gastric cancer in pregnancy: a review.

Abstract

Malignant tumors including gastric cancer (GC) are the leading cause of deaths among reproductive women. Physiological morning sickness can mask the clinical manifestations of GC, whereas the clinical presence of metastatic tumors in the abdominal cavity may be easily mistaken for abdominal swelling caused by fetal growth. Pregnancy and delivery processes in young females could accelerate the growth of GC, leading to its rapid development and grave prognosis. Therefore, early diagnosis is critical and gastrointestinal endoscopy is recommended for any suspected pregnant woman with long-term morning sickness. Treatment strategies, including chemotherapy, resection surgery and radiotherapy, will be determined based on a comprehensive consideration of the status of both the fetus and the mother. Rational management, especially clinical multidisciplinary collaboration may significantly benefit such patients.
