There is an urgent need to share expertise and offer emergency guidance for breast radiation therapy (RT) during the COVID-19 (Coronavirus) pandemic. As per the World Health Organisation (WHO) statement, our aim and obligation should be “to stop, contain, control, delay and reduce the impact of this virus at every opportunity”. In our roles as healthcare professionals and/or breast cancer experts this translates to minimising exposure of our patients to COVID-19 without compromising oncological outcome.

Contributors : Ivan Martinez ; Tayvia BrownmillerSeries Type : Expression profiling by arrayOrganism : Homo sapiensNumerous studies have implicated changes in the Y chromosome in male cancers, however few have investigated the biological importance of Y chromosome non-coding RNAs. Here, we demonstrate a group of Y chromosome-expressed long non-coding RNAs (lncRNAs) involved in male non-small cell lung cancer (NSCLC) radiation sensitivity. Radiosensitive male NSCLC cell lines demonstrated a dose-dependent induction of linc-SPRY3-2/3/4 following irradiation, not observed in radioresistant male NSCLC cell lines. Cytogenetics ...

Authors: Lin M, Li Y, Qin S, Jiao Y, Hua F Abstract Ubiquitin-like modifier-activating enzyme 7 (UBA7) is a specific E1-like ubiquitin-activating enzyme involved in interferon-stimulated gene 15 (ISG15) conjugation. UBA7 expression has been reported to be notably decreased in lung cancer. The present study aimed to investigate the changes in UBA7 expression in breast cancer and the association between UBA7 expression and clinical characteristics, and to elucidate the diagnostic and prognostic significance of UBA7 in breast cancer. The clinical data and RNA-sequencing expression values of 1,104 patients with breast ...

Kilovoltage Intrafraction Monitoring (KIM) is a novel software platform implemented on standard radiation therapy systems enabling real-time image-guided radiation therapy (IGRT). In a multi-institutional prospective trial, we investigated whether real-time IGRT improved the accuracy of the dose prostate cancer patients received during radiation therapy.

CONCLUSION: Once weekly low dose cisplatin treatment showed lower acute toxicity and a better compliance compared to once every 3 weeks high dose cisplatin treatment at the expense of a lower loco-regional control. PMID: 32212810 [PubMed - in process]

Intraoperative radiation therapy is an emerging option for adjuvant therapy for early stage breast cancer, although it is not currently considered standard of care in the United States. We applied time-driven activity-based costing to compare two alternative methods of breast intraoperative radiation therapy, including treatment similar to the techniques employed in the TARGIT-A clinical trial and a novel version with CT-guidance and high-dose-rate (HRD) brachytherapy.

The objective of this study was to characterize patients at an increased risk of distant metastasis (DM) following stereotactic body radiation therapy (SBRT) for stage I non–small cell lung cancer (NSCLC). Materials and Methods: We identified patients undergoing SBRT for stage I NSCLC between 2005 and 2016. Patients with a prior lung cancer diagnosis, receiving a biological effective dose

Conclusions: This survey highlights a critical gap in knowledge about cardiac monitoring and potentially life-saving opportunities for preventive cardiac medical management. Future studies focusing on timing and detection of RIHD may elucidate the utility of cardiac monitoring for TRT patients.
