Efficacy and Safety of Hypofractionated Radiotherapy for Nasopharyngeal Carcinoma
The purpose of this study was to evaluate the efficacy and safety of large fractionation radiotherapy in nasopharyngeal carcinoma patients, and to analyze whether Hypofractionated radiotherapy is not inferior to conventional radiotherapy.
• Age 18-75 years, male or female；
• Performance status ≤ 2 ;
• Nasopharyngeal cancer patients diagnosed by pathology (including histology or cytology) , of nasopharyngeal non-keratonic carcinoma (differentiated or undifferentiated, whether TNM staging);
• Have at least one evaluable lesion (according to Recist1.1 criteria)
• Expected survival ≥6 months.
• The main organs are functioning normally and meet the following standards: (1) Blood routine examination must meet the following criteria: (no blood transfusion within 14 days) a. HB ≥ 100g/L, b. WBC ≥3×10\^9/L c. ANC≥1.5×10\^9/L, d. PLT ≥100×10\^9/L; (2) Biochemical examination must meet the following standards: a. BIL\<1.5 times the upper limit of normal value (ULN), b. ALT and AST\<2.5ULN, GPT ≤1.5×ULN; c. Serum Cr≤1 ULN, endogenous creatinine clearance rate\>60ml/min (Cockcroft Gault formula);(3).Good coagulation function: defined as International standardized ratio (INR) or prothrombin time (PT) ≤1.5×ULN;(4).The myocardial enzyme spectra were in the normal range.
• Patients willing and able to give signed informed consent and, in the opinion of the Investigator, to comply with the Clinical Investigation Plan tests and procedures.
