Background And Objectives:
Several recent studies identified that postoperative infectious complications contribute to recurrence and poor outcome in patients with gastric cancer. This study was designed to investigate the prognostic impact of postoperative pneumonia, and to identify the putative risk factors for its occurrence.
Methods:
We retrospectively analyzed 1,415 consecutive patients who underwent curative gastrectomy for gastric cancer between 1997 and 2013.
Results:
A total of 31 (2.2 %) patients developed postoperative pneumonia (Clavien-Dindo classification ≥II). Patients with postoperative pneumonia showed a significantly poorer prognosis than patients without (P < 0.001). Concerning the occurrence of postoperative pneumonia, univariate and multivariate analyses identified older age (≥65 years; P = 0.010; odds ratio [OR] 3.59), lower nutritious status (albumin <3 0; P = 0.029; OR 4.51), advanced stage (pStage ≥II; P = 0.045; OR 2.35), concurrent hypertension (P = 0.042; OR 2.21) and total gastrectomy (P = 0.026; OR 2.42) as independent risk factors.
Conclusions:
Postoperative pneumonia was shown to be associated with long-term poor outcome in patients with gastric cancer. Care should be taken for patients with clinical factors such as older age, lower nutritional status, advanced stage, concurrent hypertension, and total gastrectomy.
