The aim of this study was to evaluate the impact of intensity-modulated radiation therapy (IMRT) on the incidence and severity of chronic dysphagia in patients with head and neck cancer. 62 evaluable patients with head and neck cancer who were treated with IMRT with or without concurrent chemotherapy were analysed. The majority of the patients (77.4%) had(More)
BACKGROUND The present study was conducted to evaluate the technical feasibility, safety and adequacy of surgical margins with salvage transoral robotic surgery (TORS) for recurrent or residual head and neck squamous cell carcinoma patients. MATERIALS AND METHODS Thirty patients who underwent salvage TORS using the 'DaVinci' robot were enrolled in the(More)
The aim of this observational prospective study was to determine the technical feasibility, safety and adequacy of surgical margins for transoral robotic surgery (TORS) in oropharyngeal cancers. From March 2013 to May 2014, 60 patients with oropharyngeal lesions underwent TORS with or without neck dissection using the ‘DaVinci’ robot. Patients were observed(More)
Adenoid cystic carcinoma of trachea is rare and is associated with prolonged survival and better prognosis. It is often misdiagnosed as chronic bronchitis or asthma. The ideal treatment option is surgical resection with tracheal reconstruction followed by adjuvant radiotherapy. Post operative radiotherapy may decrease the risk of local recurrence, but has(More)

MATERIALS AND METHODS This is a retrospective analysis of women who presented with primary,(More)
BACKGROUND This study was undertaken to report the results of weekly combination chemotherapy with cetuximab in recurrent/metastatic head and neck squamous cell carcinoma (R/M SCCHN). MATERIALS AND METHODS Retrospective analysis of 35 R/M SCCHN patients who received cetuximab with weekly paclitaxel and platin (cisplatin/carboplatin) from SCCHN August 2006(More)
Results of the studies are reported relating to application of the silanized nanostructured zirconia, electrophoretically deposited onto indium tin oxide (ITO) coated glass for covalent immobilization of the monoclonal antibodies (anti-CYFRA-21-1). This biosensing platform has been utilized for a simple, efficient, noninvasive, and label-free detection of(More)
Buccal mucosal cancer is commonly seen in India with patients presenting in advanced stages of the disease. Its excision commonly mandates division of parotid duct as a part of disease or its margin. We have adopted a simple method to salvage the parotid gland by cannulating the duct and rerouting the saliva into the oral cavity at a different site. This(More)
OBJECTIVE The report presents an 11-year Institutional experience of 203 cases with superior gingivobuccal sulcus tumours receiving surgical intervention at a comprehensive tertiary cancer care centre. METHODS A retrospective chart review of patients with a confirmed diagnosis of squamous cell carcinoma of superior gingivobuccal sulcus was done and data(More)
BACKGROUND AND OBJECTIVES In females, raising a pectoralis major myocutaneous flap is challenging and primary closure of flap donor site causes breast deformity with medial displacement of nipple areola complex. To avoid this distortion, a new method of donor site closure is devised. METHODS A parasternal skin paddle which has better vascularity is(More)
