COLORECTAL CANCER: ASSOCIATION BETWEEN SOCIODEMOGRAPHIC VARIABLES AND THE ADHERENCE TO CANCER SCREENING.

Background: Colorectal cancer (CRC) is a worldwide health problem whose control depends on public policy establishment and effective prevention and screening programs. In Brazil, there are few studies related to adherence to screening methods.

Aims: The aim of this study was to evaluate the association between demographic and socioeconomic to adherence to CRC screening with fecal immunochemical test (FIT) among average-risk individuals for CRC.

Epidemiological, Clinical, and Genomic Profile in Head and Neck Cancer Patients and Their Families.

Inherited cancer predisposition genes are described as risk factors in head and neck cancer (HNC) families. To explore the clinical and epidemiological data and their association with a family history of cancer, we recruited 74 patients and 164 relatives affected by cancer. The germline copy number alterations were evaluated in 18 patients using array comparative genomic hybridization.

Germline variants in DNA repair genes are associated with young-onset head and neck cancer.

The genetic predisposition to head and neck carcinomas (HNSCC) and how the known risk factors (papillomavirus infection, alcohol, and tobacco consumption) contribute to the early-onset disease are barely explored. Although HNSCC at early onset is rare, its frequency is increasing in recent years. Germline and somatic variants were assessed to build a comprehensive genetic influence pattern in HNSCC predisposition and patient outcome.

Risk Factors and Outcomes of Postoperative Neck Hematomas: An Analysis of 5,900 Thyroidectomies Performed at a Cancer Center.

 Postoperative neck hematoma (PNH) is an uncommon but potentially-lethal complication of thyroid surgery.  To identify the risk factors for postthyroidectomy hematoma requiring reoperation, the timing, the source of the bleeding, the related respiratory distress requiring tracheotomy, and the late outcomes.  We retrospectively analyzed the records of 5,900 consecutive patients submitted to surgery for thyroid diseases at a single institution.

Retroauricular endoscope-assisted versus conventional submandibular gland excision for benign and malignant tumors.

Background: Surgical scars are a significant cosmetic problem, especially when in exposed areas such as the anterior neck. To avoid or reduce visible scarring, diverse innovative surgical approaches to the neck have been introduced. The purpose of this study was to evaluate the feasibility and safety of the endoscopic resection using the retroauricular approach for submandibular gland excision.

Impact of scalpel type on operative time and acute complications in thyroidectomies.

Introduction: Thyroidectomy is the most common surgery in the cervical region. Currently, several techniques are available for intraoperative hemostasis.

Objective: To compare the performance of three techniques (monopolar and bipolar electrical and ultrasonic) on operative time and postoperative complications.

Variations and results of retroauricular robotic thyroid surgery associated or not with neck dissection.

Background: Technological advances in the last decades allowed significant evolution in head and neck surgery toward less invasive procedures, with better esthetic and functional outcomes, without compromising oncologic soundness. Although robotic thyroid surgery has been performed for some years now and several published series reported its safety and feasibility, it remains the center of significant controversy. This study shows the results of a case series of robotic thyroid surgery, combined or not with robotic neck dissection.

Safe implementation of retroauricular robotic and endoscopic neck surgery in South America.

In the last three decades, otolaryngology and head and neck oncological surgery have shown remarkable progress with the development of several modalities of endoscopic-assisted minimally invasive surgeries. More recently, the Da Vinci robotic surgery system has promoted the development of several surgical approaches with less morbidity and better cosmetic results, including the transaxillary and retroauricular approaches for thyroid surgery and neck dissections. In South America, there are several shortcomings regarding financial resources as well as the lack of support for innovation leading to a significant delay in adoption of numerous technological advances in medical practice.

Retroauricular endoscopic and robotic versus conventional neck dissection for oral cancer.

There has been a significant increase in concern towards improving aesthetic and functional outcomes without compromising the oncologic effectiveness in head and neck surgery. The aim of the current study is to assess the feasibility and oncological outcome of the retroauricular approach for endoscopic and robot-assisted selective neck dissection (SND) for oral cancer in comparison with the conventional SND. A retrospective single institute cohort study was designed.

Clinicopathologic analysis of 14 cases of odontogenic myxoma and review of the literature.

Background: Odontogenic myxoma is a rare benign neoplasm that originates from odontogenic ectomesenchyme. There is no standard of care and recurrences are frequent after conservative surgical procedures.

Material And Methods: A retrospective study conducted at a single cancer center, with analysis of medical records of all patients diagnosed with odontogenic myxoma from 1980 to 2010, along with a literature review.

Robotic-assisted modified retroauricular cervical approach: initial experience in Latin America.

Objective: to evaluate the thickness of the gastric wall at the time of intra gastric balloon (IGB) placement, at the time of its withdrawal and one month after withdrawal.

Methods: fifteen morbidly obese patients underwent the introduction of IGB under general anesthesia. In all patients, there was infusion of 500ml of distilled water in the balloon for the test.

Retroauricular Endoscope-Assisted Approach to the Neck: Early Experience in Latin America.

Introduction There has been a significant increase in concern towards improving aesthetic and functional outcomes without compromising the oncologic effectiveness in head and neck surgery. In this subset, endoscope-assisted and robotic procedures allowed the development of new approaches to the neck, including the retroauricular access, which is now routinely used, especially in Korea. Objectives This study aims to provide a descriptive analysis of our initial experience with retroauricular endoscope-assisted approach assessing feasibility, safety, and aesthetic results.

Late surgical outcomes of carotid resection and saphenous vein graft revascularization in patients with advanced head and neck squamous cell carcinoma.

Background: In head and neck squamous cell carcinoma, invasion of the carotid artery is a severe mortality predictor. We report an updated experience of 19 patients who underwent head and neck resection for squamous cell carcinoma with concomitant carotid reconstruction. This study aims to analyze overall survival rates, primary patency of the reconstructions, vascular and nonvascular complications, radiotherapy dosing as well as late follow-up and outcomes.

Analysis of surgical margins in oral cancer using in situ fluorescence spectroscopy.

Unlabelled: Oral cancer is a public health problem with high prevalence in the population. Local tumor control is best achieved by complete surgical resection with adequate margins. A disease-free surgical margin correlates with a lower rate of local recurrence and a higher rate of disease-free survival.
