OBJECTIVES The purpose of study was to determine the clinical efficacy of primary tumor volume measurements of different primary sites in the oropharynx compared to the oral cavity. METHODS A retrospective analysis of 85 patients with oral cavity or oropharynx cancer. The tumor area was manually outlined from axial magnetic resonance (MR) series. The software calculated the tumor volumes, aut...

Cancer of the oral cavity, also known as “oral cavity cancer” or more simply “oral cancer”, affects the tongue, gingiva, floor of mouth, palate, tonsils and oropharynx.1, 2 However, the most common form of oral cancer, oral squamous cell carcinoma (OSCC), can affect any tissue lined with oral mucosal epithelium.2, 3 Oral cancer is one of the most common malignancies in the world, ranking eighth...

Introduction: Oral mucositis induces severe oral pain in head and neck cancer patients. There is at this point no effective pain treatment without considerable side effects. Objective: The aim of this pilot study was to investigate pain reduction in oral cavity and pharynx in patients with head and neck cancer (HNC) with oral mucositis, the location of anesthetic effect, and duration of pain re...

BACKGROUND The purpose of this study was to investigate oncological and functional results of enoral laser microsurgery in treatment for cancer of the oral cavity. METHODS A retrospective chart analysis was carried out. Two hundred thirty-two patients with cancer of the oral cavity were treated by enoral laser microsurgery ± selective neck dissection ± postoperative (chemo)radiotherapy. RES...

Cancer of the oral cavity is a widely prevalent disease and has been listed as sixth most common cancer worldwide [1]. Squamous cell carcinoma (SCC) accounts for about 90% all these cases [2]. Despite tremendous research over last 70 years, overall prognosis remains at 50% with no gender difference [3].

OBJECTIVES To estimate the magnitude of association and identify the aetiological fraction (AF) attributable to smoking in the development of different types of cancers in Brazil. SETTING We conducted a case-control study, including 231 102 patients registered in the Cancer Hospital Registries (CHR) in the period from 1998 to 2011. PARTICIPANTS A total of 204 131 cancer cases relating to 30...

Background: Human papillomaviruses (HPV) are implicated in cervical cancer and, recently in oral cancer. In Mexico, there are few studies on oral cancer, therefore the interest in identifying the HPV frequency of low and high risk in samples of the oral and cervical cavities, and determining some risk factors. Objective: To determine the frequency of high and low risk HPV infection in the oral ...

Oral cavity and pharynx cancer, even when considered together, is a fairly rare disease. Implementation of multivariate modeling with lung and bronchus cancer, as well as melanoma cancer of the skin, could lead to better inference for oral cavity and pharynx cancer. The multivariate structure of these models is accomplished via the use of shared random effects, as well as other multivariate pri...
