Background: Generally, clinicians do not accurately estimate life expec-tancy in terminally ill patients with cancer. Aim: To evaluate the value of the Prognostic Nutritional Index (PNI) for accurately estimating the life expectancy of patients with end-stage oral cancer. Design: A longitudinal section study. Setting/participants: Fifteen patients (12 men;mean age: 71.7 years) who died of oral cancer between 2005 and 2014 (the terminal group) were included. The mean PNI values at the initial visit and at 3, 2, and 1 months before the deaths were comparatively analyzed. Results: The mean follow-up period was 133 days. At the initial examination, the PNI values were 49.1 ± 4.5 (p = 0.6723). The PNI value of the terminal group was 35.6 ± 5.1 at 2 months before death and 28.6 ± 3.0 at 1 month before death. The PNI values at 3, 2, and 1 months before death in the terminal group significantly differed from each other and from that at the initial visit and steadily decreased until death. Conclusions: Our findings suggest the utility of PNI as a prognostic index in patients with end-stage oral cancer patients. Furthermore, the PNI should be routinely considered in the nutritional management of patients with oral cancer nearing death.

Objective: Postoperative acute exacerbation of idiopathic interstitial pneumonia (IIP) is a serious complication in patients with lung cancer. This study was aimed to investigate risk factors for postoperative acute exacerbation of IIP in surgery for primary lung cancer. Method: We evaluated retrospectively 37 IIP patients combined with primary lung cancer who underwent lung resection for lung cancer from January 2006 and March 2010. Preoperative and perioperative clinical data were collected and analyzed. Results: Ten of 37 patients (27.0%) developed acute exacerbation of IIP after surgery for primary lung cancer and five patients (13.5%) died of progressive respiratory failure. There was no significant difference in preoperative clinical factors between acute exacerbation (AE) group and non-acute exacerbation (non-AE) group. In perioperative factors, the duration of anesthesia is significantly longer in AE group than in non-AE group. Conclusion: These data suggest that it is unable to predict postoperative acute exacerbation of IIP from preoperative clinical data. Perioperative and postoperative management might be important to prevent acute exacerbation of IIP combined lung cancer.
