Lung cancer is the most common cancer in the world today, in terms of both incidence and mortality. Non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancers, and the majority of people diagnosed with NSCLC have locally advanced or metastatic disease. Treatment algorithms have rapidly changed in the last 10 years because of the introduction of new chemotherapeutic and targeted agents in clinical practice. SUN is a 1-year longitudinal observational multicenter study that has consecutively enrolled patients affected by stage IIIB or IV NSCLC with the aim to describe the pattern of care and evolving approaches in the treatment of advanced NSCLC. 987 consecutive NSCLC patients were enrolled between January 2007 and March 2008 at the 74 participating centers throughout Italy and a 12-month follow-up was performed. Cyto-histological diagnosis was performed mainly by broncoscopy with only 24% by CT-scan guided fine-needle aspiration biopsy. 91.4% of the patients received a first-line medical treatment and 8.6% supportive care only. Median age of patients receiving first-line treatment was 66 years. First-line chemotherapy consisted of a single agent in 20% of patients and combination chemotherapy in 80%. The most frequently used chemotherapy regimens were cisplatin plus gemcitabine and carboplatin plus gemcitabine. Median survival of patients receiving first-line chemotherapy was 9.1 months. 32% percent of patients received a second-line treatment that consisted of chemotherapy in 71% of cases and erlotinib in 29%. Overall third-line treatment was given to 7.3% of patients. These results showed a pattern of care for advanced NSCLC that reflects the current clinical practice in Italy at the study time with a high adherence to the International guidelines by the Italian Oncologists., (Copyright © 2011 Elsevier Ireland Ltd.

Localized fibrous tumours of the pleura (LFTP) are rare, generally benign and asymptomatic neoplasms, which originate from the pleural layers. We report on the case of a 67 year old woman who had a 1.5 cm diameter pulmonary nodule in the right upper lobe, which had been found by chance. Video-assisted thoracoscopy (VAT) was used to excise the nodule. The diagnosis of localized fibrous tumour of the interlobar pleura was made on microscopic evaluation. After 17 months, the patient is well and her chest radiographic image is normal.

The objective of this study was to verify whether the assay of carcinoembryonic antigen (CEA) in bronchoalveolar lavage fluid (BALF) can increase the sensitivity and specificity of serum CEA for the diagnosis of lung cancer. We examined 72 subjects, 53 males and 19 females, 18 affected with peripheral lung cancer (10 adenocarcinoma, 6 squamous cell carcinoma, 1 small cell lung cancer, 1 adenosquamous carcinoma), 19 with acute pneumonia, 14 with chronic obstructive pulmonary disease (COPD), 6 with interstitial lung disease (ILD), and 15 healthy subjects. CEA was assayed in blood and in BALF using microparticle enzyme immunoassay (MEIA) (IMX Abbott). The mean serum CEA value in the lung cancer group did not differ from that in each group of non-neoplastic subjects, neither was it different from that in healthy subjects. The mean BALF CEA in patients with lung cancer, pneumonia, and COPD was significantly increased compared with that in healthy subjects, whereas there was no difference between the three groups of patients. The ratio of BALF CEA was not significantly different in the three groups of patients. There were no differences according to the histological type of the tumour (adenocarcinoma or squamous cell carcinoma). Based on the results in healthy subjects, the upper limits of normal were defined for serum CEA, BALF CEA, and CEA/albumin ratio. Thus, the sensitivity of BALF CEA in detecting lung cancer (50%) was higher than that of serum CEA (33%), although clinically not useful. In addition, BALF CEA had only 59% specificity compared to 100% of serum CEA. The diagnostic accuracy was 79% for serum CEA and 56% for BALF CEA.(ABSTRACT TRUNCATED AT 250 WORDS)

A 61 year old man presented with chronic bronchitis, which he had been suffering from for many years, and reported the recent onset of polyuria with polydipsia. A chest X-ray showed a peripheral pulmonary nodule in the right lower lobe, that was diagnosed as small cell lung cancer following histological examination of the pulmonary tissue specimen, obtained with transbronchial biopsy. After establishing the central origin of the diabetes insipidus, its cause was revealed by magnetic resonance imaging of the brain, that demonstrated metastasis to the hypothalamic-neurohypophyseal area.
