The aim of this study was to investigate the impact of a distal subtotal gastrectomy on the quality of life (QoL).
The QoL data of 126 patients were obtained on their 5th annual follow-up visit after a curative distal subtotal gastrectomy for gastric cancer (Group A). The QoL data of 130 age- and gender-adjusted healthy population were obtained from the individuals who visited the health screening center for a medical check-up (Group B). There were 42 women and 84 men in the study group and their mean age was 56.0±11.1 years. QoL was assessed using the Korean versions of the European Organization for Research and Treatment of Cancer (EORTC) QoL Questionnaire Core 30 (QLQ-C30) and QLQ-STO22.
The EORTC QLQ-C30 global health status and QoL scores of Group A and Group B were 63.9±22.7 and 61.3±22.1, respectively (p=0.361). Group A revealed a better score for emotional functioning (84.1±16.1 and 75.2±21.4, respectively; p<0.001), cognitive functioning (82.0±16.4 and 75.0±21.4, respectively; p=0.004) and fatigue (27.7±20.8 and 33.8±23.2, respectively; p=0.028). However, Group A revealed a worse score for nausea and vomiting (14.8±20.0 and 10.2±16.0, respectively; p=0.042), financial difficulties (14.8±22.9 and 7.1±16.1, respectively; p=0.002), reflux (16.7±17.7 and 10.1±17.0, respectively; p=0.003), eating restrictions (13.6±15.2 and 6.6±10.2, respectively; p<0.001) and body image (23.3±25.4 and 16.2±24.6, respectively; p=0.023).
The QoL of long-term survivors after a distal subtotal gastrectomy is still influenced by the surgery itself even though they are considered to be free of disease.

Although the vascular endothelial growth factor (VEGF) superfamily has been identified to critically influence tumor-related angiogenesis, the prognostic significance of a VEGF expression in gastric cancer is still controversial. Accordingly, the present study analyzed the VEGF-A and VEGF-C expressions and their impact on the prognosis of patients with gastric cancer.
Three hundred seventy-five consecutive patients who underwent surgical resection for gastric adenocarcinoma with a curative intent were enrolled in the present study. Immunohistochemical staining for VEGF-A and VEGF-C was performed using the formalin fixed, paraffin embedded tumor tissues.
Positive VEGF-A and VEGF-C expressions were observed in 337 (90.1%) and 278 (74.9%) cases, respectively. The survival analysis showed that the expression of VEGF-A and VEGF-C had no effect on the OS and DFS. On the multivariate analysis that included age, gender and the TNM stage, no significant association between the grade of the VEGF-A or VEGF-C expression and survival was observed.
The current study suggests that the tissue expression of VEGF-A or VEGF-C alone is not an independent prognostic marker for patients with surgically resected gastric adenocarcinoma.
