Objective: Our study aims to analyse and compare the efficacy, adverse effect profile and survival among the Paclitaxel/Cisplatin/5-Flurouracil (TPF) induction chemotherapy and Paclitaxel/carboplatin (PC) first line or cisplatin chemotherapy in a high-volume tertiary care cancer centre.

Materials And Methods: 215 patients with oral cavity cancer were recruited in this study. Patients with stages I-IIc underwent surgical resection or radiation therapy 66-74 GY/fraction.

Gamma-papillomaviruses, though traditionally classified as cutaneotropic, actual tissue tropism is largely unexplored. This study aimed to evaluate the tissue-specific prevalence of two novel-HPV 223 and 225 in samples of oral mucosa and keratinized epithelium of varied skin parts from 226 female and male subjects, with or without neoplastic/dysplastic lesions in oral cavity or cervix. The gamma-human papillomavirus (gamma-HPV) 223 and 225 DNA presences were determined by polymerase chain reaction (PCR) ursing the HPV type-specific primers and confirmed by Sanger sequencing.

In locally advanced cases of carcinoma larynx, which are being treated with total laryngectomy, routine excision of the thyroid gland (either total or hemi section) is carried out. This study was carried out to evaluate the requirement of routine thyroidectomise with total laryngectomy. An analysis of the final histology of 83 patients, who underwent the traditional treatment, together with the preoperative contrast enhanced CT scan was carried out.

Purpose: The tumor suppressor protein p53 is known to control cell cycle arrest and apoptosis. Lupeol is a phytochemical that has been found to induce apoptosis in different cancer types through the extrinsic pathway. As yet, however, its role in the induction of cell cycle arrest and apoptosis through the intrinsic pathway in head and neck cancer has not been investigated.

Epidermal growth factor receptor (EGFR) and its downstream elements are overexpressed in most cases of the head and neck squamous cell carcinoma. This study investigated the expression pattern of key proteins linked to the EGFR pathway in laryngeal carcinoma patients with a history of cannabis smoking. We selected 83 male glottic cancer patients, aged between 45 to 75 years with three distinct populations-nonsmoker, cigarette smoker, and cannabis smoker.

Content of tumor microenvironment (TME) is varied greatly among different types of laryngeal tumors, namely, supraglottic, glottic and subglottic tumors. These three different TMEs shape infiltrating monocytes/macrophages toward M2 genotypes in variable degrees. Results obtained from in vitro studies demonstrated extent of expression of M2 phenotypic features on macrophages was maximum after their exposure to supraglottic laryngeal tumor cell lysates (SLTCL) than glottic or subglottic lysates.

In an aim to rectify dysregulated CC chemokine receptor (CCR5)/ligand (RANTES, MIP-1α, MIP-1β) status of monocytes/macrophages in tongue squamous cell carcinoma (TSCC; n = 12) patients, we have tested interferon α2b (IFNα2b), a novel immunomodulator with wide use in the management of several forms of cancer. IFNα2b can upregulate reduced CCR5 expression and increases the suppressed secretory status of its ligands, as evidenced from in vitro studies on monocytes/macrophages from the peripheral blood of TSCC patients as well as healthy individuals. Isolated monocytes of TSCC patients (n = 5) undergoing chemotherapeutic treatment along with IFNα2b immunotherapy demonstrated significant upregulation in CCR5 expression and secretion of corresponding ligands.

Background: Preoperative lymph node screening of all neck compartments is favored by clinicians for the management of the neck. The presence of a metastatic node on one side of the neck reduces the 5-year survival rate to 50%, and the presence of a metastatic node on both sides of the neck reduces the 5-year survival rate to 25%.

Materials And Methods: This study compared the evaluation of lymph node metastases by ultrasonography (USG) and computed tomography (CT) in patients with squamous cell cancer of the head and neck region.
