    <p>Abstract</p> <p>Background</p> <p>The purpose of this study was to identify the risk factors associated with fatal pulmonary hemorrhage (PH) in patients with locally advanced non-small cell lung cancer (NSCLC), treated with chemoradiotherapy.</p> <p>Methods</p> <p>The medical records of 583 patients with locally advanced NSCLC, who were treated with chemoradiotherapy between July 1992 and December 2009 were reviewed. Fatal PH was defined as PH leading to death within 24 h of its onset. Tumor cavitation size was defined by the cavitation diameter/tumor diameter ratio and was classified as minimum (< 0.25), minor (≥ 0.25, but < 0.5), and major (≥ 0.5).</p> <p>Results</p> <p>Of the 583 patients, 2.1% suffered a fatal PH. The numbers of patients with minimum, minor, and major cavitations were 13, 11, and 14, respectively. Among the 38 patients with tumor cavitation, all 3 patients who developed fatal PH had major cavitations. On multivariate analysis, the presence of baseline major cavitation (odds ratio, 17.878), and a squamous cell histology (odds ratio, 5.491) proved to be independent significant risk factors for fatal PH. Interestingly, all patients with fatal PH and baseline major cavitation were found to have tumors with squamous cell histology, and the occurrence of fatal PH in patients having both risk factors was 33.3%.</p> <p>Conclusions</p> <p>Patients at high risk of fatal PH could be identified using a combination of independent risk factors.</p

    BACKGROUND: In approximately the year 2000, the results of a number of important studies of non-small-cell lung cancer (NSCLC) were published. METHODS: Between July 1992 and December 2003, 223 patients with NSCLC aged > or = 70 years received chemotherapy alone as their initial treatment at the National Cancer Center Hospital East. These patients were divided into 2 groups: those that began treatment between 1992 and 1999 (group A) and between 2000 and 2003 (group B). The details of chemotherapy regimens and outcomes were compared. RESULTS: In group A, 83% of patients received platinum-based chemotherapy, two-thirds of these regimens comprised platinumplus second-generation combination chemotherapy. In contrast, although 55% of patients received platinum-based chemotherapy in group B, 41% of patients received non-platinum-based chemotherapy. Among patients in group B, performance status was significantly associated with the selection of platinum-based or non-platinum-based chemotherapy; age was marginally associated with this selection. Median survival time (MST), 1-year survival rate, and 2-year survival rate were 6.7 months, 14%, and 7%, respectively, in group A, and 8.1 months, 35%, and 20% in group B (p=0.0109). Multivariate analysis revealed that clinical stage and administration of salvage chemotherapy were independent prognostic factors. CONCLUSIONS: In and after the year 2000, chemotherapy regimens changed greatly and survival of elderly patients significantly improved in our institute, and this improvement appears to be attributable mostly to the effect of salvage chemotherapy. These results suggest that even elderly patients should be offered salvage chemotherapy regardless of age, if possible
