| Sumario: | Abstract Data about primary gastric adenosquamous carcinoma (ASC) was limited due to rare incidence. Thus, the present study aims to investigate clinicopathological features and prognosis of gastric ASC. Cases of gastric ASC were obtained from our center and from case reports and series extracted from Medline. Clinicopathological features and prognosis of gastric ASC were analyzed and compared with gastric adenocarcinoma (AC) in our center. The commonest location was lower third (45.0%), followed by upper (26.2%) and middle third (24.2%). The median tumor size was 6 cm (0.8–17). The commonest differentiation status was well for both AC (44.4%) and SCC components (40.9%). Half of tumors (52.7%) were stage T4 and most patients (86.2%) suffered from lymph node metastasis (LNM). Tumor depth and TNM stage were risk factors for overall survival (OS) (both P < 0.05). The distribution of age, tumor size, tumor location, tumor depth, LNM and TNM stage were significantly different between gastric ASC and AC (all P < 0.05). The OS of gastric ASC was significantly worse than AC (P < 0.001), especially in stage III disease (P < 0.001). Gastric ASC differ significantly from AC with respect to clinicopathological features. The prognosis of gastric ASC was worse than AC. |
