The sharp rise in the frequency of adenocarcinoma and relative decrease of squamous cell carcinoma of the respiratory and digestive systems, raises suspicion of a common element in their carcinogenetic cascade, which could result in similar trends in cell-type distribution changes of esophageal and lung cancers. The possible role of chemical irritation caused by gastroesophageal reflux disease (GERD) in non-small cell lung cancer (NSCLC) patients was investigated. There was no significant difference between the adenocarcinoma and the squamous cell carcinoma groups, neither in the composite DeMeester scores nor in any of the separate parameters of the complex score investigated. However, the ratio of detected gastroesophageal reflux cases was considerably higher than in the average population. This factor may be one element of a multifactorial cancer promotion.

Postoperative pneumonia is a serious complication following pulmonary resection. Aspiration of oesophageal reflux contents is known to cause pulmonary complications in patients with a history of gastrectomy. In this study, we compared the incidence of postoperative pneumonia in patients with or without previous gastrectomy. A retrospective review was conducted of clinical charts for patients who underwent radical pulmonary resection for non-small cell lung cancer from January 2006 to December 2010. Pneumonia was diagnosed with chest computed tomography findings in all cases. A total of 333 patients underwent pulmonary resections during the study period. Twenty-seven patients (8.1%) had a history of gastrectomy. Eight patients (2.2%) had postoperative pneumonia. All eight patients who developed postoperative pneumonia did not have pneumonia before pulmonary resection. Of the aforementioned 27 patients, five (18.5%) developed pneumonia postoperatively, whereas only three of 325 patients who did not have a history of gastrectomy (0.9%) had pneumonia (P < 0.001). In multivariate analysis, a history of gastrectomy had the highest impact on the odds ratio (8.81) for postoperative pneumonia. A significantly higher incidence of postoperative pneumonia was found in patients with a history of gastrectomy. Prophylactic treatment, such as premedication with ranitidine, should be considered in those patients.
