Effectiveness of the Henna Application in Patients With Hand-Foot Syndrome: Nested Case-Control Study

Introduction: There is an explanation that there is a connection between the application of henna and the occurrence of hand-foot syndrome, and the purpose and progression of this interaction. This nested case-control study of participants who underwent capecitabine therapy were breast and colorectal cancer was carried out to prospectively investigate the relationship of hand-foot syndrome with the henna application. Method: Nested Case-Control (NCC) design within a longitudinal observational prospective cohort study in the setting of an oncology clinic. The primary outcome was hand-foot syndrome from in-hospital interviews and medical record reviews. In the data collection process, 84 patients received capecitabine and two patients (1:2) who met the inclusion criteria served as the control group (n=56, who received the test) for each case (n=28). The case and control groups were followed for 12 weeks. HFS-14 Scale and EORTC QLQ-C30 Quality of Life were conducted on the baseline, first follow-up (T1=day 21), and second follow-up (T2=day 63) cycles of chemotherapy. We used a non-parametric signed-rank test to test the median of paired differences.
