Background: Chemotherapy-induced peripheral neuropathy (CIPN) has become a substantial problem because of specific cytotoxic agents such as nab-paclitaxel, oxaliplatin, and eribulin. In addressing CIPN-related side effects caused by nab-PTX, we previously reported better CTCAE v4.0 grades and superior nab-PTX dose maintenance in breast cancer treatment adopting our 3S approach. Our 3S approach combines compression therapy (stockings and sleeves applied 24 hours from the beginning of nab-PTX administration) with medication therapy (selected prophylactic medications goshajinkigan, lafutidine, and mecobalamin applied over the course of treatment). In revisiting how stocking use restored skin perfusion levels decreased by nab-PTX chemotherapy, we examined whether the skin perfusion increases differ by CIPN grade. Methods: Using a laser Doppler blood flow meter with integrated probe (NL-101 Nahri Nexis Japan), we measured the skin perfusion of the lower limbs before and after stocking use across four groups: three groups of 3S prophylactics-treated nab-PTX patients divided by CIPN grade (Grade 0 [G0, n=12], Grade 1 [G1, n=20], Grades 2 and 3 combined [G2+3, n=12]), and one control group of healthy volunteers (GH, n=50). Results: In the control group (GH), the mean increase in skin perfusion level (mL/min/100g) after wearing stockings was 0.90 (SD= 3.36). For the 3S prophylactic treatment patients, the mean increase was 4.25 (4.98) in the G0 group, 2.11 (4.93) in the G1 group, and 2.69 (2.53) in the G2+3 group. ANOVA analysis indicated a significant difference in skin perfusion increase among the groups (p=0.0493). Analysis between the groups indicated significance in the G0 group increase over the control group increase (p=0.0255). Conclusions: CIPN was previously shown to decrease skin perfusion; in the current study skin perfusion responsiveness to stockings differed significantly between chemotherapy patients and healthy volunteers. Restorative skin perfusion increase is potentially related with alleviating CIPN grade, for which further evaluation is needed.
