We evaluated the efficacy of dose de-escalation to the normal larynx using conformal radiotherapy (CRT) for T1/T2 glottic cancer. For conventional RT (2DRT, n = 38), the laryngeal box received a median equivalent dose in 2 Gy fractions (EQD2) of 66 Gy. For CRT (n = 42; 3D-CRT, 20; intensity-modulated RT, 22), clinical target volume (CTV)1 (gross tumor with a 3-mm margin) and CTV2 (laryngeal box) received median EQD2s of 66.6 Gy and 52.2 Gy, respectively. With a 71-month median follow-up, five-year local control and overall survival rates for 2DRT vs...

Cardiac resynchronization therapy (CRT) is an established therapy for heart failure and can be delivered through a CRT pacemaker (CRT-P) or a CRT defibrillator (CRT-D). CRT-P devices are smaller and less expensive, have better battery longevity, and have been subject to fewer recalls and advisories but cannot deliver high-energy shocks to terminate potentially lethal ventricular arrhythmias. As published guidelines do not distinguish between CRT-P and CRT-D indications, we examined the practice of prescribing these devices in older women and men with heart failure...

PURPOSE: Management of cT4b bladder cancer is poorly defined; national guidelines recommend chemotherapy (CT) alone or chemoradiation (CRT). Using a large, contemporary dataset, we evaluated national practice patterns as well as associated outcomes, especially with respect to radical cystectomy (RC) and CRT versus CT alone. METHODS: The National Cancer Data Base was queried (2004-2013) for patients diagnosed with cT4bN0-3M0 bladder cancer. Patients were divided into 5 treatment groups: CT alone, CRT, RC (with/without CT/radiotherapy [RT]), other treatment (subtherapeutic RT with/without CT), or no treatment...

Enteral feeding is often required for nutrition support in head and neck cancer patients when oral intake is inadequate. When to initiate the insertion of a feeding tube continues to be a debated issue in our institution. We investigated the use of reactive feeding tubes (RFTs) in patients with advanced stage oropharynx cancer (OPC). Data were retrospectively collected on 131 patients who had radiotherapy (RT) ± chemotherapy from 2005 to 2015. Predictors for RFT insertion were investigated. Weight loss during RT was compared between those with RFT versus prophylactic tubes (PFTs) versus no tube, and survival outcomes evaluated...

QRS duration has been associated with the response to cardiac resynchronization therapy (CRT). However, the methods for defining QRS duration to predict the outcome of CRT have discrepancies in previous reports. The aim of this study was to determine an optimal measurement of QRS duration to predict the response to CRT.Sixty-one patients who received CRT were analyzed. All patients had class III-IV heart failure, left ventricular ejection fraction not more than 35%, and complete left bundle branch block. The shortest, longest, and average QRS durations from the 12 leads of each electrocardiogram (ECG) were measured...
