Background
It is important to determine the effect of clinical factors on several domains (symptoms, living status, and quality of life [QOL]) after gastrectomy to establish individualized therapeutic strategies. This study was designed to determine the factors—particularly surgical method—that influence certain domains after gastrectomy for proximal gastric cancer by using the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45) questionnaire.
Methods
We conducted a nationwide study of PGSAS-45 questionnaire responses retrieved from 1950 (82.5%) patients from 70 institutions who had undergone gastrectomy for gastric cancer. Of these, 1,538 responses for proximal gastric cancer (1020 total gastrectomies and 518 proximal gastrectomies [PGs]) were examined.
Results
PG significantly and favorably affected four main outcome measures (MOMs): elderly affected 10 MOMs, male sex affected 4 MOMs, longer postoperative period affected 8 MOMs, preservation of the vagus nerve affected 1 MOM, adjuvant chemotherapy affected 1 MOM, clinical stage affected 2 MOMs, and more extensive lymph node dissection affected 2 MOMs. However, the laparoscopic approach had an adverse effect on MOMs and combined resection of other organs had no favorable effect on any MOMs.
Conclusions
This PGSAS NEXT study showed that it is better to perform PG for proximal gastric cancer, even for patients with advanced cancer, to obtain favorable postoperative QOL if oncological safety is guaranteed. Because the MOMs of PGSAS-45 are positively and negatively influenced by various background factors, it also is necessary to provide personalized care for each patient to prevent deterioration and further improve symptoms, living status, and QOL postoperatively.
