There is a scarce clinical experience about adjuvant helical tomotherapy (HT) in patients affected by malignant pleural mesothelioma (MPM) even though it appears as a useful technique to treat complex volume as the pleural cavity, and seems to have better dose distribution than the "classic" intensity modulated radiotherapy (IMRT). ⋯ With limited follow up, HT has comparable toxicity to those observed with traditional IMRT. Higher radiation dose and good coverage results in excellent local control.

Coexistence of pulmonary nodules in operable non small cell lung cancer (NSCLC) may influence the therapeutic indication. The aim of this study was to evaluate prospectively the prevalence and the probability of malignancy of pulmonary nodules in operable lung cancer. ⋯ Diagnosis of satellite nodules associated with early stage NSCLC is common. We developed a predictive score to estimate the probability of malignancy which may be a precious aid in the management of pulmonary nodules associated to a NSCLC.

Comparative Study
Quantitative Perfusion Scintigraphy or Anatomic Segment Method in lung cancer resection.
Quantitative Perfusion Scintigraphy (QPS) and Anatomic Segment Method (ASM) are two techniques for estimating postoperative pulmonary function. QPS is gold standard, but holds disadvantages. ⋯ QPS and ASM are remarkably similar in predicting postoperative pulmonary function. As ASM underestimates pulmonary function more, it could be a safe alternative from a cost-benefit point of view. Based on these results, it appears that QPS could be restricted to patients in whom ASM suggests functional inoperability, although further prospective studies are necessary.

Although concurrent chemotherapy and radiation is the standard approach for good risk unresectable stage III non-small cell lung cancer (NSCLC) patients, there is no optimal concurrent chemotherapy regimen. Administration of chemotherapy at full dose with maximal activity against local and micrometastatic disease is highly desirable. This study tested the feasibility of 3 cycles of full dose cisplatin and pemetrexed concurrent with definitive thoracic radiotherapy followed by consolidation pemetrexed, without the dose-limiting toxicity (DLT) exceeding 33% of the patients. ⋯ Three systemic dose levels of pemetrexed and cisplatin could be administered concurrently with radiotherapy. The rate of survival at 24 months was encouraging.

The aim of this study is to evaluate the prognostic factors and outcome of patients operated for adenosquamous (ADS) carcinoma of the lung, in comparison with adenocarcinoma (AD) and squamous cell carcinoma (SCC). ⋯ ADS are uncommon and extremely aggressive lung tumors. Adjuvant chemotherapy should be administered even in Stage I radically resected tumors. A whole brain postoperative prophylactic radiotherapy could be proposed to reduce risk of developing brain MTS.
