LP strategies should be considered only in patients with resectable stage III/IV larynx and hypopharynx SCC, ideally those who have a functional larynx. The choice of treatment must be discussed by a multidisciplinary team, and the patient must have an active role in making the decision. CRT and IC-RT are both approved larynx-preservation approaches.

However, with the development of molecular biology in recent decades, more tumors are increasingly being genetically studied and, in several of them, molecular classifications have been created (the most widely studied and used is that for breast cancer). Colon and rectum cancer are no exception.

El tratamiento óptimo aún es controvertido, en especial respecto a la extensión de la cirugía, indicaciones de radioyodo y la supresión de la hormona estimulante de la tiroides. La correcta evaluación de los riesgos, antes y después de la cirugía, facilita un selectivo enfoque del tratamiento; destacando la relevancia de revisar el impacto de la medicina nuclear en la correcta evaluación, tratamiento y seguimiento de los pacientes que padecen esta neoplasia.

The objective of this review is to report to the medical community the most recent knowledge on prevention and management of dermatitis with the use of cetuximab simultaneously with radiotherapy in the treatment of squamous cell carcinomas of the head and neck. A review was conducted in PubMed of English language publications between 2010 and 2015. The search employed the terms 'skin toxicity', 'radiodermatitis', 'cetuximab', 'radiotherapy', and 'head and neck cancer'.

The major component tumor of these syndromes is medullary thyroid carcinoma (MTC). To date, somatic mutations in RET have been identified in tumors from individuals with MEN 2 finding.

Objective: This study aimed to describe our experiences and compare them to other published cases.
Materials And Methods: From May 2009 to August 2015, the files of all patients with CC treated at our referral center were reviewed.
Introduction: Thyroglosal duct cyst is a common anomaly with an incidence of 7% in adults, the rate of carcinoma in TGDC is 0.7-1.6%, and are extremely rare those originated in the hyoid bone.
View Article and Find Full Text PDFOropharyngeal cancer incidence has recently increased, thereby attracting public attention. Akin to other malignancies of the upper aerodigestive tract, it has been attributed to the carcinogenic effects of tobacco and alcohol use. However, recent evidence shows that a substantial increase in the disease is attributable to the effects of human papillomavirus (HPV).

Glioblastoma multiforme is one of the most aggressive central nervous system tumors and with worse prognosis. Until now,treatments have managed to significantly increase the survival of these patients, depending on age, cognitive status, and autonomy of the individuals themselves. Based on these parameters, both initial or recurrence treatments are performed, as well as monitoring of disease by imaging studies.

Anterior exposure for cervical chordomas remains challenging because of the anatomical complexities and the restoration of the dimensional balance of the atlanto-axial region. In this report, we describe and analyze the transmandibular transoral approach and multilevel spinal reconstruction for upper cervical chordomas. We report two cases of cervical chordomas (C2 and C2-C4) that were treated by marginal en bloc resection with a transmandibular approach and anterior-posterior multilevel spinal reconstruction/fixation.

However, the involvement of different medical specialties has changed the focus of treatment and triggered a number of controversies. In the absence of controlled trials, the guidelines for treatment are founded on prognostic factors for survival and local control, the effects of the treatments, and comorbidities.

Mandibular reconstruction is done with microvascularized free flaps, but noticeable differences in shape and size exist in relation to the normal mandible; consequently, new reconstructive methods are desirable. We explored the feasibility of recovering osseous viability using a sterilized mandibular segment reconstituted with autologous bone marrow.

Their role impact in several moments during the management of an oncological patient: prevention, diagnosis, assessment of the spread of the disease, curative treatment, management of the sequels, complications by the treatment and not less important, the palliation. The current state of the surgical oncology as a result of a constant development, inspired by skillful hands with creative and restless minds, have achieved to mark the history of the medicine in an area which currently has a great transcendence and an accelerated growth in a short period of time.

Methods: We managed patients with concomitant treatment of cetuximab (400 mg/m(2) as uploading dose, then 250 mg/m(2), IV) concomitant with gemcitabine (50 mg/m(2)) weekly for seven courses, and radiotherapy in classical fractionation until completion of 70 Gy. Primary endpoints were complete response (CR) to treatment and toxicity.
Background: Thyroid cancer presents as nodules. Thyroid nodules are frequent, but only 5-30% are malignant. Fine needle aspiration biopsy (FNAB) is useful for initial evaluation; nevertheless, malignancy is uncertain when follicular neoplasm is reported.
