The p53 tumour suppressor gene is inactivated in various types of human cancers, and has been implicated as an early event in several cancers. A p53 Pro/Arg polymorphism at exon 4 codon 72, has been suggested to be involved in susceptibility to cancers as well. Hence, in the current study, we investigated p53 exon 4 codon 72 polymorphism using Proline or… (More)
A retrospective study of 20 patients treated at the Tata Memorial Hospital over a period of 50 years, 1941-1991, is presented. Seventy-five percent (15/20) of the patients presented before their fifth decade with a male-to-female ratio of 2:1. The commonest presenting symptom was a painless lump in the neck. Twenty-five percent (5/20) had an incisional… (More)
The presence of high risk human papilloma virus (HPV) 16 and 18 was examined in 100 oral cancer patients of Indian descent, 80 patients with potentially malignant oral lesions and corresponding clinically normal mucosa from 48 of these patients. Additionally, presence of HPV-33, -6 and -11 was also studied in 86 oral cancers, 50 potentially malignant oral… (More)
We present a rare case of neurilemmoma of the larynx, which was excised through a lateral thyrotomy approach with resulting restoration of laryngeal function. The advantage of the lateral thyrotomy approach for submucous tumours of the larynx is discussed.
Deregulation of oncogenes and tumor suppressor genes involved in apoptosis has been associated with tumor development and progression. To investigate the involvement of apoptosis regulating proteins in oral cancer in Indian patients, primarily associated with chewing tobacco habits, immunohistochemical expression of bcl-2 and bax was examined in 63 oral… (More)
Although vascular malformations of the tongue comprise a significant portion of head and neck angiodysplastic lesions, hemangioma of base of tongue is rare. We report a case of hemangioma of base of tongue extending to the supraglottis, which necessitated an extended supraglottic laryngectomy. Patient had an uneventful recovery and at three year, follow-up… (More)
The base of the tongue, valleculae, preepiglottic space, and supraglottic area of the larynx develop from an unpaired central area, i.e., "hypobranchial eminance," unlike oral tongue and vocal cords, which are independently unilateral and paired in character. These areas should be known as "base of tongue-supraglottic complex." Lymphatic criss-cross is… (More)
We examined 103 oral squamous cell carcinomas (OSCC), 100 oral lesions consisting primarily of leukoplakia (82 cases), and 76 clinically normal mucosa specimens from the contralateral site in the oral cavity of individuals with oral lesions, for the presence of Epstein-Barr virus (EBV). Polymerase chain reaction (PCR) was used to amplify a 239 bp fragment… (More)
We have investigated loss of heterozygosity of p53 tumor suppressor gene in Indian oral cancer patients, individuals with premalignant leukoplakia lesions, and corresponding normal mucosa, to study the status of p53 alleles in oral cancer pathogenesis. Fifty oral cancers, and 42 oral leukoplakia lesions and corresponding clinically normal oral mucosa from… (More)
Synchronous multicentric giant cell tumour (MGCT) is a rare occurrence. We report a young woman who presented with a synchronous skull and lower shaft femur giant cell tumour, who had previously received radiotherapy to both the sites, it being deemed inoperable at initial assessment.
