Several randomized prospective studies on breast cancer patients have proved the safety of neoadjuvant chemotherapy. These trials have also demonstrated that tumor down staging does indeed improve the eligibility for breast conservative surgery without increasing local recurrence rates with possibly an improved survival. However, complete pathologic(More)
BACKGROUND Recent epidemiological data have implicated human papilloma virus (HPV) infection in the pathogenesis of head and neck cancers, especially oropharyngeal cancers. Although, HPV has been detected in varied amounts in persons with oral dysplasia, leukoplakias and malignancies, its involvement in oral tongue carcinogenesis remains ambiguous. (More)
Oral cancer has a well characterized progression from premalignant oral epithelial changes to invasive cancer, making oral squamous cell carcinoma an optimal disease for chemoprevention interventions prior to malignant transformation. The primary goal of chemoprevention here is to reverse, suppress, or inhibit the progression of premalignant lesions to(More)
Lung cancer remains the leading cause of cancer-related mortality in the world despite advances in the field of cancer therapeutics. Traditional treatment with empirically chosen cytotoxic chemotherapeutic agents, have given small, but real survival benefits. Recent advances and insights into molecular pathogenesis of lung cancers have provided some novel(More)
The biology and clinical behavior of Head and Neck Squamous Cell Carcinomas (HNSCCs) is very distinct within different subgroups due to the distinct molecular profiles for the HPV positive versus HPV negative tumors. HPV status is the most important independent prognostic variable in multivariate analysis taking into account all other prognostic factors(More)
Branchial cleft anomalies are caused by incomplete regression of the cervical sinus of "His" during the 6(th) and 7(th) weeks of embryologic development. Although congenital in origin, first branchial cleft cysts (FBCCs) can present later in life. FBCCs are rare causes of parotid swellings, accounting for <1% of all the branchial cleft abnormalities. The(More)
BACKGROUND Oral tongue squamous cell carcinoma (OTSCC) is the most common cancer diagnosed within the oral cavity worldwide. Many studies in India report OTSCC ranking among the top two most common subsites within the oral cavity. India is often labeled the oral cancer capital of the world. The incidence of tongue cancers in the population-based cancer(More)
BACKGROUND Lung cancer remains a major cause of morbidity and mortality worldwide, accounting for more deaths than any other cancer cause. AIM The aim of this study was to analyze the clinical profile and the epidemiological trends in lung cancer patients from a single centre with an emphasis on the smoking practices. MATERIALS AND METHODS This is a(More)
Reconstructive microsurgery for oral and maxillofacial (OMF) defects is considered as a niche specialty and is performed regularly only in a handful of centers. Till recently the pectoralis major myocutaneous flap (PMMC) was considered to be the benchmark for OMF reconstruction. This philosophy is changing fast with rapid advancement in reconstructive(More)
