Evaluation of erectile potency and radiation dose to the penile bulb using image guided radiotherapy in the CHHiP trial.
This study aimed to generate PB dose constraints based on dose-volume histograms (DVHs) in patients treated with prostate radiotherapy, and to identify clinical and dosimetric parameters that predict the risk of ED post prostate radiotherapy. Materials and methods: Penile bulb DVHs were generated for 276 patients treated within the randomised IGRT substudy of the multicentre randomised trial, CHHiP. Incidence of ED in relation to dose and randomised IGRT groups were evaluated using Wilcoxon rank sum, Chi-squared test and atlases of complication incidence. Youden index was used to find dose-volume constraints that discriminated for ED. Multivariate analysis (MVA) of effect of dosimetry, clinical and patient-related variables was performed. Results: Reduced treatment margins using IGRT (IGRT-R) produced significantly reduced mean PB dose compared with standard margins (IGRT-S) (median: 25 Gy (IGRT-S) versus 11 Gy (IGRT-R); p
CONCLUSION: Structural prevention measures in addition to behavioral measures enable a reduction of the cancer risk caused by UV radiation. The aim must be to establish these measures nationwide for the entire population. PMID: 32494842 [PubMed - as supplied by publisher]
This study sought to determine the incidence rates of all gynecologic, including peritoneal, malignancies in the U.S. Active Duty population compared to the general US population as reported in the Surveillance, Epidemiology, and End Results Program database. MATERIALS AND METHODS: Gynecologic cancers diagnosed in U.S. Active Duty women aged 20-59 between 2004 and 2013 were retrospectively ascertained. Cancer cases were identified in both the Automated Central Tumor Registry and the Military Health System Data Repository. All cases in Automated Central Tumor Registry plus cases recorded in Military Health System Data R...

CONCLUSIONS: Our data provide new insights into the biology driving metastasis in PTCs and highlight how lncRNAs cooperate with coding transcripts to sustain these processes. PMID: 32495722 [PubMed - as supplied by publisher]
CONCLUSIONS: Fusion genes were the most common genetic cause of pediatric PTCs. Fusion gene positive PTCs showed more aggressive behavior than fusion gene negative PTCs. Several novel rearrangements were identified. Fusion genes seem to be a molecular marker number one in pediatric PTC patients. PMID: 32495721 [PubMed - as supplied by publisher]
LUNG CANCER symptoms include difficulty breathing, headaches, and persistent chest pain. But you could also be at risk of an advanced tumour if you develop a subtle sign on your eyes. Could you be at risk of lung cancer?

Conclusions: RT, despite modern techniques, affects the sexual function of PCa patients in varying degrees. Reducing radiation doses to penile structures may play a role in preventing erectile dysfunction.
CONCLUSION: The most predictive factor of 3yED was the dose to the PB. This may be explained by variation in individual patients' anatomy and this could allow for the development of better strategies to prevent ED. PMID: 30761939 [PubMed - as supplied by publisher]
