In thymomas, MG, WHO histology and Masaoka stage are inter-related. MG has an influence on histology and stage at presentation, while two clinical/histologic patterns are more likely: early Masaoka stage A/AB WHO type and high Masaoka stage/B WHO type. Among the three factors, only Masaoka stage had a prognostic significance on OS and DFS. Our results suggest that a consistent staging system for thymomas should take into account all three variables.

Background: Surgery is considered an effective therapeutic option for patients with lung metastasis (MTS) of colorectal cancer (CRC). The purpose of the study was to evaluate efficacy and feasibility of lung metastasectomy in CRC patients and to explore factors of prognostic relevance. Methods: This is a retrospective study of patients operated for lung MTS of CRC from 2004 to 2012 in a single Institution. Overall survival (OS) was the primary endpoint. Secondary endpoints were progression free survival (PFS) in resection status R0 and OS in in patients submitted to re-resections. In order to evaluate prognostic factors, a multivariable Cox proportional hazard model was performed.Results: One-hundred eighty-eight consecutive patients were included in the final analysis. The median follow-up (FU) was 45 months. The 5-year OS and PFS were 53% (95% CI: 44-60%) and 33% (95% CI: 25-42%), respectively. Two-and 5-year survival after re-resection were 79% (95% CI: 63-89%) and 49% (95% CI: 31-65%), respectively. Multivariate adjusted analysis showed that primary CRC pathological TNM stages (P=0.019), number of resected MTS ≥5 (P=0.009) and lymph nodal involvement (P<0.0001) are independent predictors of poor prognosis. Conclusions: Patients operated and re-operated for lung MTS from CRC cancers showed encouraging survival rates. Our results indicated that primary CRC stage, number of MTS and lymph nodal involvement are strong predictive factors. Prognosis after surgery remained comforting up to four resected MTS. Adjuvant chemotherapy seems to have a benefit on survival in patients affected by multiple metastases.Finally, according to the high rate of unidentified lymph node involvement in pre-operative setting, lymph node sampling should be advisable for a correct staging. randomized trial and the undefined role of metastasectomy remained the unsolved problem in the management of patients with pulmonary metastasis (MTS) of CRC (5).The purpose of the study was to evaluate the efficacy and the feasibility of lung metastasectomy in colorectal cancer (CRC) in our institution. Moreover, we aimed at exploring prognostic factors for survival and evaluating survival pattern in patients submitted to re-resections. MethodsWe included all consecutive patients who underwent lung metastectomy for pulmonary metastases from CRC at Department of Thoracic Surgery, University of Torino, Italy-from 2004 to 2012. Data were retrospective collected from the surgical registry of our Department. Follow-up (FU) data were acquired by routine visits, telephone contacts or from administrative data (outpatient regional registry). FU was completed over July 2014. Our Institutional Review Board approved the study. Inclusion criteria for lung metastasectomy comprised locally controlled primary CRC, no evidence of extra-thoracic lesions excluding hepatic metastases, single or multiple pulmonary nodules suitable for a radical resection. Stage of primary CRC was assigned according to the Union Internationale Contre le Cancer (UICC) staging system. Pre-op...

The finding of MVI in pT1-T2N0 NSCLC is frequent. MVI correlates with adenocarcinoma histotype, increased tumor dimensions, and tumor-infiltrating lymphocytes. The presence of MVI is an independent negative prognostic factor. In our experience, MVI was a stronger prognostic indicator than T size in T1a-T2b categories according to the 2009 TNM staging system.
