Abstract:
Objective To investigate the clinical manifestations,pathological diagnosis,treatment meth-od and prognosis of primary gastric adenosquamous carcinoma.Methods The clinical data of 20 patients with primary gastric adenosquamous carcinoma receiving the treatment in this hospital from January 1,2013 to No-vember 30,2022 were retrospectively analyzed,and their clinicopathological characteristics and prognosis were analyzed.Results Among the 20 patients,14 cases were male and 6 cases were female,with a median age of 59(36,74)years old.Upper abdominal discomfort,pain and weight loss were the main clinical symptoms.Ser-um carbohydrate antigen 19-9(CA19-9)levels were elevated in some patients.The image examination indica-ted the gastric occupation.Among 20 cases,the tumors were most common in the lower third of the stomach(14 cases),followed by the upper third(1 case)and the middle third(5 cases).The most common tumors were in the lower one-third(14 cases)of the stomach,followed by the middle one-third(5 cases)and upper one-third(1 case).In histomorphology,the gastric tumor cells contained two components,adenocarcinoma and squamous cell carcinoma,and squamous cell carcinoma accounted for more than 25％of tumor cells.Immuno-histochemistry showed that the partial tumor cells of adenocarcinoma expressed CK8/18 and partial tumor cells of squamous cell carcinoma expressed p40.All 20 cases performed the surgical treatment.Only 6 cases survived and the others died of tumor recurrence or metastasis.The adenosquamous carcinoma proportion and Ki-67 were correlated with the prognosis in the patients with gastric adenosquamous carcinoma(P＜0.05).The survival curve constructed by the Kaplan-Meier method showed that when the proportion of squamous carcinoma was more than 35％,the prognosis of the patients was good.Conclusion Primary gastric adenosquamous carcinoma,mainly composed of adenocarcinoma,may be correlated with a higher risk of metastasis.
