BackgroundThe incidence of human papillomavirus (HPV)-positive oropharyngeal cancer, a disease affecting younger patients, is rapidly increasing. Cetuximab, an epidermal growth factor receptor inhibitor, has been proposed for treatment de-escalation in this setting to reduce the toxicity standard cisplatin treatment, but no randomised evidence exists efficacy strategy.MethodsWe did open-label controlled phase 3 trial at 32 head and neck centres Ireland, Netherlands, UK, patients aged 18...

BackgroundAdjuvant trastuzumab significantly improves outcomes for patients with HER2-positive early breast cancer. The standard treatment duration is 12 months but shorter could provide similar efficacy while reducing toxicities and cost. We aimed to investigate whether 6-month adjuvant non-inferior the 12-month regarding disease-free survival.MethodsThis study an open-label, randomised phase 3 non-inferiority trial. Patients were recruited from 152 centres in UK. randomly assigned cancer,...

<h2>Summary</h2><h3>Background</h3> Most newly diagnosed oropharyngeal and hypopharyngeal cancers are treated with chemoradiotherapy curative intent but at the consequence of adverse effects on quality life. We aimed to investigate if dysphagia-optimised intensity-modulated radiotherapy (DO-IMRT) reduced radiation dose dysphagia aspiration related structures improved swallowing function compared standard IMRT. <h3>Methods</h3> DARS was a parallel-group, phase 3, multicentre, randomised,...

<h3>Importance</h3> Patients with breast cancer remain at risk of relapse after adjuvant therapy. Celecoxib has shown antitumor effects in preclinical models human cancer, but clinical evidence is lacking. <h3>Objective</h3> To evaluate the role celecoxib as an addition to conventional therapy for women ERBB2 (formerly HER2)–negative primary cancer. <h3>Design, Setting, and Participants</h3> The Randomized European Trial (REACT) was a phase 3, randomized, double-blind study conducted 160...

Two postmenopausal women with breast cancer developed acute confusion and seizures, less than 24 hours after the first cycle of neoadjuvant chemotherapy fluorouracil, epirubicin low-dose cyclophosphamide. They were found to have severe, life-threatening hyponatraemia sodium levels 113 115 mEq/L, respectively. Both made a full recovery within admission slow correction levels. Following investigational workup, most likely diagnosis was cyclophosphamide-associated syndrome inappropriate...

Objective: Attempts have been made to model the contribution of concomitant chemotherapy radiotherapy in terms biological effective dose (BED) for major squamous cell carcinoma (SCC) sub-sites. Despite SCC’s sharing common aetiology, different chemoradiotherapy regimens are used clinical practice. This study aims compare BED across SCC sub-sites using two radiobiological models; intuitive and Poisson methods its calculation. Methods: Phase 3 trials versus conventional fractionation head...

Abstract Introduction: The addition of adjuvant chemotherapy to hormonal therapy is recommended for patients with lymph node-positive (LN+ve), estrogen receptor positive (ER+), HER2-ve early breast cancer, despite the fact that many women will remain disease-free even if they do not receive chemotherapy. Therefore, a number LN+ EBC may be unnecessarily exposed toxicities no treatment benefit. In UK, Oncotype DX® Recurrence Score (RS) by NICE routine testing in ER+ HER2-ve, node negative...
