The most common cancers diagnosed during pregnancy are breast and cervical cancer, followed by leukaemia, lymphoma, melanoma and thyroid cancer (Pavlidis 2002). Gastric cancer during pregnancy is extremely rare at approximately 1/1000 (Gonzalez-Mesa et al. 2014). The symptoms of gastric cancer are non-specific and most of these symptoms are frequently seen during pregnancy. Therefore, most cases of pregnancyassociated gastric cancers are diagnosed at advanced stages. The management of a pregnant patient with gastric cancer is very challenging and needs a multidisciplinary team. There are two conflicting issues in pregnancy associated gastric cancer: early treatment of the maternal gastric cancer and the continuation of pregnancy. We present here a case of advanced gastric cancer which was diagnosed in the second trimester of pregnancy. As far as we know, this case is the first published report of pregnancy-associated gastric cancer in Iran.
