With great improvements in survival in patients with locally advanced prostate cancer, quality of life (QOL) is becoming an important factor in the selection of treatment. The aim of this study was to evaluate changes in health-related QOL in patients with locally advanced prostate cancer after intensity-modulated radiotherapy (IMRT) combined with androgen deprivation therapy. Patients were treated with IMRT combined with androgen deprivation. ⋯ The changes in scores for urinary incontinence and dysuria were -13.0 ± 8.3 and -6.12 ± 3.9, respectively (P < 0.05). QOL was decreased in patients with locally advanced prostate cancer after IMRT combined with androgen deprivation therapy in all four primary domains, especially in urinary, bowel, and hormonal domains. Nevertheless, the treatment was well tolerated in most patients during the 5 years of follow-up.

The exhaled breath temperature (EBT) has been proven to be the expression of airways inflammation as well as of the increased vascularity. Although both these conditions characterize lung cancer pathogenesis, this is the first study where the EBT has been analysed in patients affected by non-small-cell lung cancer. The aim of this study was to verify whether and how the lung cancer being examined influences the EBT for possible future clinical implications. ⋯ The EBT was correlated with number of packs/year and associated with the stage of lung cancer. We identified a cut-off value for the EBT that is able to screen patients with lung cancer with a high sensitivity and specificity. Our results suggest that lung cancer causes an increase in the EBT, which, whether confirmed and validated, could become a new non-invasive clinical tool in the screening and monitoring of this disease.

Gastric cancer (GC) is one of the most frequent cancers worldwide. Recent studies have shown that long noncoding RNAs (lncRNAs) play critical roles in multiple biological processes, including oncogenesis. The present study aimed to evaluate the potential role of lncRNA H19 in GC. qRT-PCR was performed to investigate the expression of H19 in tumor tissues and corresponding non-tumor lung tissues from 80 patients with GC and in GC cell lines. ⋯ MTT and colony formation assays confirmed that H19 expression affects GC cell proliferation in vitro. Furthermore, exogenous c-Myc significantly induces H19 expression, and the expression of H19 was positively correlated with the c-Myc levels in the 80 samples used in our study (Pearson correlation coefficient = -0.687). In conclusion, our study demonstrates that the altered expression of lncRNA H19, which is induced by c-Myc, is involved in the development and progression of GC by regulating cell proliferation and shows that H19 may be a potential diagnostic and prognostic target in patients with GC.

Multicenter Study
HBsAg is an independent prognostic factor in diffuse large B cell lymphoma patients in rituximab era: result from a multicenter retrospective analysis in China.
This study mainly focused on the impact of Hepatitis B virus (HBV) infection on the prognosis of diffuse large B cell lymphoma (DLBCL) patients in rituximab era, using a Cox regression model to ascertain the prediction value of the serum HBV marker in survivals. Three hundred and eighty four DLBCL patients treated with rituximab, cyclophosphamide, doxorubicin/epirubicin, vincristine and prednisone (R-CHOP-like regimens) or CHOP-like regimens were included. ⋯ In the CHOP group, HBV infection has not been found a profound impact on the survivals. In the R-CHOP group, PFS and OS were inferior in HBsAg-positive patients (p=0.031 and p=0.006, respectively); after adjusting for International Prognostic Index parameters, HBsAg is an independent unfavorable factor for both PFS (RR=2.492) and OS (RR=2.589).
