Abstract

Background/Aim: Surgery for elderly patients with gastric cancer is becoming more common. However, the risk factors of the laparoscopic surgery for these patients are unknown, and thus it is difficult to determine appropriate treatments for such patients. The aim of this retrospective study was to clarify the risk factors for the treatment outcomes after laparoscopic gastrectomy in elderly patients. Patients and Methods: Two hundred twenty-two patients who underwent laparoscopic gastrectomy for primary gastric cancer between January 2014 and December 2017 were enrolled. Clinical characteristics and short- and long-term prognoses were analyzed in 47 patients aged 75 years or older (elderly group) and in 175 patients who were under 75 years old (non-elderly group). Results: The presence of comorbidities was more common in the elderly group than in the non-elderly group (91.5% vs. 61.7%, p<0.0001). The rate of postoperative complications in the elderly group was significantly higher than that in the non-elderly group (42.6% vs. 22.9%, p=0.01). The 5-year overall survival rate was significantly lower in the elderly group than in the non-elderly group (66.9% vs. 92.2%; p<0.0001). In the elderly group, 5-year overall survival in patients with a low preoperative prognostic nutritional index (PNI) was significantly worse than that in patients with a high preoperative PNI (25.0% vs. 80.9%; p<0.05). Multivariate analysis showed that the PNI value was independently associated with overall survival in elderly patients who underwent laparoscopic gastrectomy (p<0.05). In particular, the rate of non-cancer deaths after surgery in elderly patients was significantly higher than that in non-elderly patients (p<0.05). Conclusion: PNI value is an independent prognostic factor for overall survival in elderly patients who have undergone laparoscopic gastrectomy for gastric cancer; therefore, in elderly patients with low preoperative PNI, attention should be paid not only to recurrence of cancer, but also to the deterioration of general condition caused by malnutrition.
