    ABSTRACT: The number of resected lymph-nodes (#RNs) has proven prognostic in breast and colorectal cancer. Here we evaluated its prognostic impact in a series of resected NSCLC patients. A panel of established prognostic factors plus (1) #RNs or (2) the ratio between the number of metastatic nodes and #RNs (NR) were correlated to overall- (OS), cancer-specific- (CSS), and disease-free-survival (DFS), using the Cox-model. Risk-classes according to hazard ratios (HR) were generated. Internal and external validation was accomplished. A dataset of 415 resected NSCLC patients was retrieved. At multivariate analysis, #RNs and NR were independent factor for longer OS, CSS and DFS (p<0.0001). Patients with a #RNs>10 (identified optimal cut-off) had a statistically significant OS (p=0.02) and DFS (p=0.0005) benefit. In node-positive patients, a NR<9% significantly correlated with better outcome. Stratification into High-, Medium-, and Low-Risk classes, based on High- (HRFs: stage, N-status, age, #RNs) and Intermediate-Risk Factors (IRFs: sex, grading, histology), efficiently predicted outcomes (p<0.0001). The risk class model performance was externally validated in and independent dataset of 297 patients. These results contribute to complete the panel of prognostic factors for resected NSCLC. A prospective larger validation and comparison with molecular prognostic tools is warranted.

    ABSTRACT: The aim of this study was to assess the diagnostic role of fiberoptic bronchoscopy in primitive lung cancers in relation to the sensibility, the specificity and the cost of the examination. We analysed the diagnostic flow-charts of 473 patients with suspected primitive lung cancer consecutively examined during a period of 4 years (2003-2006). The results were analysed comparing patients observed in the period 2003-2004 with those observed during 2005-2006. The number and type of samples collected and the protocols utilized were considered. In overall patients the reliability of the fiberoptic bronchoscopy was 61.7%, with a significant increase from 47.5% in 2003-2004 to 74.4% in 2005-2006. An important role in improving the diagnostic relevance of the exam was assumed by the more frequent adoption of biopsies and trans-bronchial needle aspiration on parenchyma and mediastinal lymph nodes. The fiberoptic-bronchoscopy associated to advanced tissue sampling techniques represents the gold standard for the diagnosis of lung cancer, due to high sensitivity and specificity and moderate cost.

    ABSTRACT: Epidemiological studies on malignant mesothelioma have provided evidence on the etiologic role of occupational asbestos exposure and, to some extent, domestic and residential exposures. Less attention has been given to the occurrence of mesothelioma in urban areas where large quantities of asbestos have been employed in the past. The purpose of the study was to investigate the occurrence of mesothelioma in patients living in the urban area of Rome and in other parts of the Latium Region and the patterns of asbestos exposure. A pathology-based, malignant mesothelioma archive operating in Rome, Italy, was the source of cases. Included in the survey were cases resident in Latium and diagnosed in the period January 1, 1993, through December 31, 2001. Information on asbestos exposure was derived from interviews to the patient or his/her next of kin and from available medical records. The case series included: 114 males and 53 females; total, 167. Information on asbestos exposure was available for 138 cases (83%). Occupational exposure was ascertained or suspected for 33% of cases resident in Rome and 63% of those resident in other municipalities of Latium. Sex ratio was 1.6 in Rome and 3.3 in Latium. The high prevalence of women among mesothelioma cases and lower proportion of occupational exposure in Rome versus the other municipalities of Latium suggest a possible role of environmental asbestos exposure in the urban area.
