RESUMEN
OBJECTIVE: This study aimed to demonstrate the superiority of cryocompression over cryotherapy alone in the prevention of chemotherapy-induced peripheral neuropathy (CIPN) grade 2 or above. METHODS: This prospective randomized study was conducted between May 2020 and January 2023 in Innsbruck. Eligible patients had a diagnosis of gynecological cancer and received a minimum of 3 cycles of taxane-based CT (neoadjuvant, adjuvant or palliative therapy). Patients were randomized 1:1 to receive either cryotherapy or cryocompression on their upper extremities during chemotherapy (CT). We performed temperature measurements, two QoL questionnaires and neurological tests during CT and at follow-up 3 and 6-9 months after the completion of CT. CIPN was assessed using the CTCAE score. RESULTS: Of 200 patients recruited, both groups showed a lower prevalence of CIPN in this study compared to recent literature. In the group receiving cryotherapy, the prevalence of grade 1 CIPN was 30.1 %, and that of grade 2 CIPN or above was 13.7 %; in the group treated with cryocompression, the prevalence of grade 1 CIPN was 32.8 %, and that of grade 2 or above CIPN was 17.2 %. We found a significant reduction in temperature in the cryotherapy and cryocompression groups. Regarding the two QOL questionnaires as well as the neurological tests no significant differences were found between the two groups. CONCLUSION: Our study suggests that cryotherapy as well as cryocompression is a safe and effective way to cool patients' extremities to lower the prevalence of CIPN. Cryocompression was not more effective than cryotherapy alone in the prevention of CIPN.

BACKGROUND: Adjuvant aromatase inhibitors increase osteoporosis and fractures in patients with hormone receptorpositive breast cancer. We have previously reported outcomes of the ABCSG-18 (study 18 from the Austrian Breast & Colorectal Cancer Study Group) trial showing that adjuvant antireceptor activator of nuclear factor-κB ligand denosumab treatment counteracts these adverse effects and may improve outcomes. We report here the final long-term outcomes. METHODS: ABCSG-18 is a prospective, double-blind, placebo-controlled, phase 3 trial in which 3425 postmenopausal patients with early hormone receptorpositive breast cancer receiving aromatase inhibitor therapy were randomly assigned in 58 trial centers to receive either denosumab 60 mg or placebo administered subcutaneously every 6 months. The primary end point was the time to first clinical fracture after randomization. Secondary disease outcomerelated end points were disease-free survival (DFS), bone metastasisfree survival (BMFS), and overall survival (OS). RESULTS: For this final protocol-defined analysis, median follow-up is 8 years (interquartile range, 6 to 9.6 years). There were 309 versus 368 DFS events (hazard ratio, 0.83; 95% confidence interval [CI], 0.71 to 0.97) in the denosumab versus the placebo group, respectively, resulting in an absolute 9-year DFS benefit of 3.5 percentage points (79.4 vs. 75.9%). Adjuvant denosumab improved BMFS by 2.5 percentage points (88.9 vs. 86.4%; hazard ratio, 0.81; 95% CI, 0.65 to 1.00) and OS by 1.0 percentage point (90.9 vs. 89.9%; hazard ratio, 0.80; 95% CI, 0.64 to 1.01). No new toxicities for this dose of adjuvant denosumab were observed. CONCLUSIONS: DFS, BMFS, and OS continued to show benefit in this final long-term analysis of ABCSG-18. There were no new toxicities. (Funded by Amgen; ClinicalTrials.gov number, NCT00556374.)
