Changes in Survival in Head and Neck Cancers in the Late 20th and Early 21st Century: A Period Analysis.
Summary of "Changes in Survival in Head and Neck Cancers in the Late 20th and Early 21st Century: A Period Analysis."
Abstract Background. Therapy for head and neck cancers has evolved over the past decade, but few detailed analyses of recent developments in survival on the population level have been published. Methods. We use period analysis and modeled period analysis to disclose recent trends in survival in patients with head and neck cancer. Data are derived from the Surveillance, Epidemiology, and End Results limited-use database. Results. A major, statistically significant improvement in survival was observed, with the overall 5-year relative survival rate going from 54.7% in 1992-1996 to 65.9% in 2002-2006. Subgroup analysis showed improvement in cancers of the oral cavity, tongue, tonsils, and nasopharynx, with the greatest improvements observed in tonsillar carcinoma (+22.2 percentage points) and carcinoma of the tongue (+14.4 percentage points). Further analysis of survival for oral cavity, tonsillar, and tongue carcinoma revealed improvements in survival at each stage and across all age groups except for patients aged >/=75 years, with the greatest improvement occurring in locally advanced disease and in patients aged 55-64 years for carcinoma of the tongue and tonsils and those aged 15-44 years for oral cavity cancers. Conclusions. Survival has substantially improved for head and neck cancer patients over the past decade. The greatest improvement was seen in tonsillar and tongue cancers.

Head And Neck Neoplasms
Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck. (from Holland et al., Cancer Medicine, 4th ed, p1651)
Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
Noninflammatory degenerative disease of the hip joint which usually appears in late middle or old age. It is characterized by growth or maturational disturbances in the femoral neck and head, as well as acetabular dysplasia. A dominant symptom is pain on weight-bearing or motion.
A symptom, not a disease, of a twisted neck. In most instances, the head is tipped toward one side and the chin rotated toward the other. The involuntary muscle contractions in the neck region of patients with torticollis can be due to congenital defects, trauma, inflammation, tumors, and neurological or other factors.
A late 20th-century philosophical approach or style of cultural analysis that seeks to reveal the cultural or social construction of concepts conventionally assumed to be natural or universal. (from E.R. DuBose, The Illusion of Trust: Toward a Medical Theological Ethics in the Postmodern Age, Kluwer, 1995)
Despite modern diagnostic procedures and up-to-date therapy, the survival of head and neck tumour patients is unfavourable. This can be explained by several factors, one of which is the late recogniti...
Objectives. Head and neck cancer is frequent in the Inuit population of Greenland and is characterized by a very high incidence of Epstein-Barr virus associated nasopharyngeal carcinoma (NPC). However...
BACKGROUND: Patients with a first head and neck carcinoma have a high risk of successive neoplasms, many of which appear again in the head and neck. Second head and neck tumors have a poorer prognosis...
This is a review on second primary tumors in patients with head and neck cancer. These patients have a high risk of developing other cancers simultaneously or subsequently. The incidence of multiple p...

The purpose of the research study is to evaluate effectiveness and the quality of life, specifically the risk of dry mouth, after radiation treatment for head and neck cancers.
This is a protocol to collect tissues, blood, and other specimens from patients with malignant or nonmalignant diseases of the head and neck. Collected specimens will be used in laboratory...
We propose to combine lapatinib with RT alone in patients with locally advanced head and neck cancer who cannot tolerate chemotherapy. The main objective of the study is to determine the...
The purpose of this trial is to study the clinical effects of increasing the weekly fraction number for locally advanced head and neck cancers by a multi-institutional prospective randomis...
