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.

摘要：
包括胃癌（GC）在内的恶性肿瘤是育龄妇女死亡的主要原因。生理性孕吐可以掩盖GC的临床表现，然而，腹腔转移性肿瘤的临床存在很容易被误认为是胎儿生长引起的腹部肿胀。年轻女性的怀孕和分娩过程可以加速GC的生长，导致其快速发展和严重预后。因此,早期诊断很关键，建议对任何长期孕吐的可疑孕妇进行胃肠道内窥镜检查。治疗策略,包括化疗,切除手术和放射治疗，将根据对胎儿和母亲状况的综合考虑来确定。理性管理,尤其是临床多学科合作可能会使此类患者显著受益.
