Clinical Target Volume Based on Disease Extension Risk Atlas and Computer-aided Delineation in Nasopharyngeal Carcinoma

• Status: Active, not recruiting
• Trial end date: 2022-12-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to compare individualized clinical target volume (CTV) based on disease extension risk atlas and computer-aided delineation with traditional CTV in intensity modulated radiotherapy (IMRT) for nasopharyngeal carcinoma (NPC), in order to confirm the efficacy and safety.

• Phase: N/A
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Sun Yat-sen University
• Treatments: Cisplatin; Docetaxel; Gemcitabine

Criteria

Inclusion Criteria:

• Patients with newly histologically confirmed non-keratinizing (according to WHO histologically type).

• Tumor staged as T1-4N0-3M0 (according to the 7th AJCC edition), based upon the following minimum diagnostic workup within 4 weeks prior to registration:(1) history/physical examination;(2)chest X-ray, PA and lateral OR chest CT OR PET/CT;(3) pre-treatment magnetic resonance imaging (MRI) of nasopharynx and neck, pre-treatment MRI must be done at Sun Yat-sen University Cancer Center;(4) sonography OR CT of upper abdoman OR PET/CT;(5) Bone scan OR PET/CT.

• Satisfactory performance status: Karnofsky scale (KPS) ≥ 70.

• Adequate bone marrow function based upon the complete blood count within 2 weeks prior to registration: leucocyte count ≥ 4000/μL, hemoglobin ≥ 90g/L and platelet count ≥ 100000/μL.

• Adequate hepatic function within 2 weeks prior to registration: Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST) < 1.5×upper limit of normal (ULN) concomitant with alkaline phosphatase (ALP) ≤ 2.5×ULN, and bilirubin ≤ ULN.

• Adequate renal function within 2 weeks prior to registration: serum creatinine ≤ 133 umol/L or calculated creatinine clearance ≥ 60 ml/min.

• Women of childbearing potential and male participants must agree to use a medically effective means of birth control throughout their participation in the treatment phase of the study.

• Patients must be informed of the investigational nature of this study and sign a written informed consent.

Exclusion Criteria:

• Age > 65 or < 18.

• Prior malignancy except adequately treated basal cell or squamous cell skin cancer outside head and neck region, in situ cervical cancer.

• Pregnancy or lactation (consider pregnancy test in women of child-bearing age and emphasize effective contraception during the treatment period).

• History of previous RT (except for non-melanomatous skin cancers outside intended RT treatment volume).

• Prior chemotherapy or surgery (except fine needle aspiration biopsy) to primary tumor or nodes.

• Hearing loss due to sensorineural deafness（except tumor induced conductive hearing loss).

• Any severe intercurrent disease, which may bring unacceptable risk or affect the compliance of the trial, for example, unstable cardiac disease requiring treatment, renal disease, chronic hepatitis, diabetes with poor control (fasting plasma glucose > 1.5×ULN), emotional disturbance, untreated active infectious disease, and acquired immune deficiency syndrome.

• Prior allergic reaction to the study drugs involved in this protocol.
