fluorouracil and Constriction, Pathologic

fluorouracil has been researched along with Constriction, Pathologic in 12 studies

Fluorouracil: A pyrimidine analog that is an antineoplastic antimetabolite. It interferes with DNA synthesis by blocking the THYMIDYLATE SYNTHETASE conversion of deoxyuridylic acid to thymidylic acid.
5-fluorouracil : A nucleobase analogue that is uracil in which the hydrogen at position 5 is replaced by fluorine. It is an antineoplastic agent which acts as an antimetabolite - following conversion to the active deoxynucleotide, it inhibits DNA synthesis (by blocking the conversion of deoxyuridylic acid to thymidylic acid by the cellular enzyme thymidylate synthetase) and so slows tumour growth.

Constriction, Pathologic: The condition of an anatomical structure's being constricted beyond normal dimensions.

Trial Overview

Trial Outcomes

Biomarkers Predictive of Failure

To determine biomarkers predictive of failure with either reduced or standard dose radiotherapy. (NCT01706939)
Timeframe: at 5 years

Change in MD Anderson Dysphagia Inventory (MDADI) From Baseline

MDADI is a questionnaire of 20 questions and contains a global subscale, and three other categories of questions (emotional, functional, and physical). The scores are summed and a mean score is calculated. This mean score was multiplied by 20 to obtain a score, with a range of 0 (extremely low functioning) to 100 (high functioning). Thus, a higher MDADI score represented better day-to-day functioning and better QOL. (NCT01706939)
Timeframe: Baseline and 5 years

Change in Xerostomia Questionnaire (XQ)

XQ is a nine questions survey developed specifically for xerostomia symptoms. The scores are summed and a mean score is calculated on a scale of 0 (low xerostomia interference) to 10 (high xerostomia interference). A lower or negative score reflects a better quality of life compared to baseline. (NCT01706939)
Timeframe: Baseline and 5 years

Number of Participants With Acute Toxicity of Chemoradiotherapy (CRT)

Number of participants with acute toxicity treated with reduced or standard dose CRT. (NCT01706939)
Timeframe: at 5 years

Number of Participants With Local-regional Control

Local-regional control (LRC) at 3 years in patients with advanced HPV related oropharynx cancer or unknown primary treated with reduced or standard dose radiation. (NCT01706939)
Timeframe: at 3 years

Number of Participants With Overall Survival at 5 Years

Overall Survival (OS) 5 years treated with reduced or standard dose CRT. (NCT01706939)
Timeframe: at 5 years

Change in European Organization for Research and Treatment of Cancer Questionnaire for Head and Neck (EORTC HN)

The EORTC Head and Neck module was specifically designed and validated for head and neck cancer patients. This 35-item questionnaire contains 7 symptom scales (pain, swallowing, senses, speech, social eating, social contact, and sexuality), 6 single-item scales (difficulties of teeth, mouth opening, dry mouth, sticky saliva, coughing, and feeling ill), and 5 items about the additional use of pain medicine, nutritional supplements, and feeding tube and changes in body weight. All items were transformed to scales from 0 to 100, and divided into respective sub-scores of global health (GHS), functional (FS), and symptom scale (SS). Subscales from 0-100. A high score on global health and functional scale represents a better level of functioning, whereas a high score on a symptom scale and head and neck module indicates more severe symptoms. (NCT01706939)
Timeframe: Baseline and 5 years

Change in MD Anderson Symptom Inventory Symptom Inventory and Severity (MDASI-HN SI and SS)

"MD Anderson Symptom Inventory Symptom Inventory and Severity (MDASI-HN SI and SS) MDASI Head and Neck is a site-specific MDASI module which includes the core MDASI 13 symptom severity items (SS) and 6 symptom interference items (SI), alongside 9 items relevant to head and neck cancer. The scores are summed and a mean score is calculated on a scale of 0 (low severity or interference) to 10 (high severity or complete interference). In order to calculate the mean score, a majority of the subscale's items must have been completed.~A lower or negative score reflects a better quality of life compared to baseline." (NCT01706939)
Timeframe: Baseline and 5 years

Number of Participants With Progression Free Survival (PFS)

Progression free survival (PFS) at 5 years in patients with advanced HPV related oropharynx cancer, nasopharynx cancer or unknown primary treated with reduced or standard dose radiation. (NCT01706939)
Timeframe: at 3 and 5 years
