The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) datasets allow unprecedented gene expression analyses. Here, using these datasets, we performed pan-cancer and pan-tissue identification of coding and long noncoding RNA (lncRNA) transcripts differentially expressed in tumors and preferentially expressed in healthy tissues and/or tumors. Pan-cancer comparison of mRNAs and lncRNAs showed that lncRNAs were deregulated in a more tumor-specific manner. Given that lncRNAs are more tissue-specific than mRNAs, we identified healthy tissues that preferentially express lncRNAs upregulated in tumors and found that testis, brain, the digestive tract, and blood/spleen were the most prevalent. In addition, specific tumors also upregulate lncRNAs preferentially expressed in other tissues, generating a unique signature for each tumor type. Most tumors studied downregulated lncRNAs preferentially expressed in their tissue of origin, probably as a result of dedifferentiation. However, the same lncRNAs could be upregulated in other tumors, resulting in "bimorphic" transcripts. In hepatocellular carcinoma (HCC), the upregulated genes identified were expressed at higher levels in patients with worse prognosis. Some lncRNAs upregulated in HCC and preferentially expressed in healthy testis or brain were predicted to function as oncogenes and were significantly associated with higher tumor burden, and poor prognosis, suggesting their relevance in hepatocarcinogenesis and/or tumor evolution. Taken together, therapies targeting oncogenic lncRNAs should take into consideration the healthy tissue, where the lncRNAs are preferentially expressed, to predict and decrease unwanted secondary effects and increase potency. Significance: Comprehensive analysis of coding and noncoding genes expressed in different tumors and normal tissues, which should be taken into account to predict side effects from potential coding and noncoding gene-targeting therapies.

PURPOSE: Patients with hepatocellular carcinoma (HCC) of intermediate stage (BCLC-B according to the Barcelona Clinic Liver Cancer classification) are a heterogeneous group with different degrees of liver function impairment and tumour burden. The recommended treatment is transarterial chemoembolization (TACE). However, patients in this group may be judged as poor candidates for TACE because the risk-benefit ratio is low. Such patients may receive transarterial radioembolization (TARE) only by entering a clinical trial. Experts have proposed that the stage could be further divided into four substages based on available evidence of treatment benefit. We report here, for the first time, the outcome in patients with BCLC-B2 substage HCC treated with TARE. METHODS: A retrospective analysis of the survival of 126 patients with BCLC-B2 substage HCC treated with TARE in three European hospitals was performed. RESULTS: Overall median survival in patients with BCLC-B2 substage was not significantly different in relation to tumour characteristics; 19.35 months (95% CI 8.27-30.42 months) in patients with a single large (>7 cm) HCC, and 18.43 months (95% CI 15.08-21.77 months) in patients with multinodular HCC (p¿=¿0.27). However, there was a higher proportion of long-term survivors at 36 months among those with a single large tumour (29%) than among those with multiple tumours (16.8%). CONCLUSION: Given the poor efficacy of TACE in treating patients with BCLC-B2 substage HCC, TARE

Treatment of an infected postpneumonectomy cavity is very difficult. We present a patient with an infection of a postpneumonectomy cavity by Staphylococcus epidermidis treated with local daptomycin for different dwell times, maintaining high antibiotic levels above the MIC. Clinical and microbiological cure were achieved successfully.

Sorafenib is a multi-kinase inhibitor and a vascular endothelial growth factor (VEGF) inhibitor approved to treat patients with advanced hepatocellular carcinoma, renal cell carcinoma and differentiated thyroid carcinoma. Its most common side effects are asthenia/fatigue, skin toxicity, diarrhea and arterial hypertension. Reported respiratory adverse reactions include dyspnea, cough, pleural effusion and hoarseness. The aim of this report is to describe for the first time the occurrence of pneumatocele in two patients treated with Sorafenib. Patients had no respiratory symptoms and alternative diagnoses were ruled out. Primary tumors were different (liver metastases from a pancreatic neuroendocrine tumor and hepatocellular carcinoma) but both patients had been treated with yttrium 90 radioembolization 9 and 17 months before starting on Sorafenib, respectively. No complications occurred and Sorafenib withdrawal was followed by radiologic improvement.
