Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Percent of grade 2 and 3 neuropathy according to National Cancer Institute’s Common Toxicity Criteria for adverse events (NCI-CTCAE V.4) will be compered among the two study groups (case and control), as the main outcome of the study. Timepoint: Prior to the start of study; during the chemotherapy (prior to receiving each cycle); 1 month after receiving the last dose of chemotherapy or 6 months after initiation of melatonin (each one happens earlier). Method of measurement: National Cancer Institute’s Common Toxicity Criteria for adverse events (NCI-CTCAE V.4) scale will be used by the oncologist to evaluate severity of neuropathy in the patients. According to this scale severity of neuropathy will be classified from 1 to 5. | — |
Secondary
| Measure | Time frame |
|---|---|
| Patients quality of life according to EORTC QLQ-30 questionnaire will be compared among two groups. Timepoint: Prior to the start of study; during the chemotherapy (prior to receiving each cycle); 1 month after receiving the last dose of chemotherapy or 6 months after initiation of melatonin (each one happens earlier). Method of measurement: By the persian version of EORTC QLQ-30 questionnaire.;Severity of neuropathy according to patients' declaration. Timepoint: Prior to the start of study; during the chemotherapy (prior to receiving each cycle); 1 month after receiving the last dose of chemotherapy or 6 months after initiation of melatonin (each one happens earlier). Method of measurement: By chemotherapy-induced peripheral neuropathy questionnaire (EORTC CIPN-20) which will be translated to persian language and will be validated prior to study initiation.;Severity of neuropathy according to oxaliplatin- specific scale which is evaluated by the physician. Timepoint: Prior to the start of study; during the chemotherapy (prior to receiving each cycle); 1 month after receiving the last dose of chemotherapy or 6 months after initiation of melatonin (each one happens earlier). Method of measurement: By oxaliplatin- specific scale. | — |
