Clinicopathologic Characteristics and Prognosis of Gastric Cancer in Young Patients

چکیده
To determine the clinicopathologic characteristics and prognosis of gastric cancer in young patients, a total of 1985 gastric cancer patients who had undergone gastrectomy at our hospital were reviewed. The male-to-female ratio was significantly lower in the young patients than in either the middle-aged (P < 0.0001) or elderly patients (P < 0.0001). Undifferentiated carcinoma was observed more frequently in the young patients compared with either the middle-aged (P < 0.0001) or elderly patients (P < 0.0001). Furthermore, peritoneal metastasis was observed more frequently in the young patients than in either the middle-aged (P < 0.005) or elderly patients (P < 0.005). Five-year survival rates were 61.0, 73.6 and 68.1% in the young, middle-aged and elderly patients, respectively. The prognosis of the middle-aged patients was significantly better than that of either the young or the elderly patients (P < 0.05). Multivariate analysis indicated that age was an independent prognostic factor. Peritoneal recurrence was more frequently observed in the young patients than either the middle-aged or the elderly patients (P < 0.05). Gastric cancer in young patients has unique characteristics, namely, a predominance of female patients and a high frequency of undifferentiated cancer and peritoneal metastasis and recurrence.
