A global survey on the utilization of cryotherapy and compression therapy for the prevention of chemotherapy-induced peripheral neuropathy

A meta-analysis of the utility of cryotherapy for preventing peripheral neuropathy among breast cancer patients receiving paclitaxel and nab-paclitaxel

BACKGROUND

Cryotherapy with taxane infusion is a noninvasive strategy for preventing peripheral neuropathy (PN), but the efficacy of this approach has not been proven.

METHODS

A systematic search was conducted, and 477 records were initially identified. The titles were screened independently by 2 reviewers. Fourteen studies were ultimately included for meta-analysis, which was conducted using the meta package in the R software. Only studies that analysed cryotherapy use in breast cancer patients who received paclitaxel or nab-paclitaxel were included. Relative risks (RRs) were calculated using the random effects model to compare the occurrence of PN between the paclitaxel and nab-paclitaxel groups.

RESULTS

The incidence of Common Terminology Criteria for Adverse Events (CTCAE) grade ≥ 2 PN was 24.85% (81/326) in the cryotherapy arm and 42.35% (72/170) in the placebo arm. The overall RR CTCAE grade ≥ 2 PN in the cryotherapy group compared with the placebo group was 0.45 [0.27, 0.77, p = 0.0031]. The RR for sensory PN was 0.19 [0.05, 0.66, p = 0.009], and that for motor PN was 0.18 [0.03, 0.99, p = 0.0491]. The RR for Patient Neurotoxicity Questionnaire (PNQ) scores ≥ D, which indicate severe neuropathy, was 0.24 [0.09, 0.62; p = 0.0035]. Cold intolerance was the most reported t adverse effect, with a prevalence of 15% (37/247).

CONCLUSIONS

The use of cryotherapy decreased the occurrence of CTCAE grade ≥ 2 PN by 55%. Cold intolerance was the most frequently reported adverse effect associated with cryotherapy, but this adverse effect did not lead to high discontinuation rates.

The Effect of Cold Therapy on the Prevention of Chemotherapy-Induced Peripheral Neuropathy in Oncology Patients: A Systematic Review Study

OBJECTIVE

The aim of this study was to investigate the effect of cold therapy on the prevention of chemotherapy-induced peripheral neuropathy in oncology patients.

METHODS

This review was prepared based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The Medline, CINAHL, Embase, Cochrane Library, PubMed, Scopus and Web of Science databases were searched for studies published between January 1997 and June 2024. Two reviewers independently evaluated study suitability and extracted data. The Jadad critical appraisal scale and Methodological Index for Non-Randomized Studies (MINORS) risk of bias tool was used for quality assessment. The findings of this review are presented using a narrative synthesis.

RESULTS

Overall, cold therapy was effective in preventing CIPN in more than half of the studies. Cold therapy methods such as cold hilotherapy, frozen gloves and socks, cold mitts and slippers, and cooling gloves/socks were found to be the most effective in six studies. In contrast, three studies that applied interventions like frozen gloves and socks, crushed ice, and various cooling methods did not show a significant effect.

CONCLUSION

Cold therapy was found to be a reasonable option for preventing CIPN in patients receiving taxane-based chemotherapy, as it does not result in serious side effects. Due to the heterogeneity of studies with different methods, sample sizes and measurement procedures for CIPN, it is difficult to make a clear statement about the duration and temperature of cold application that the patient can tolerate.

IMPLICATIONS FOR NURSING PRACTICE

Cold therapy can provide a useful option for the prevention of CIPN in patients receiving taxane-based chemotherapy. Nurses should increase patient and provider awareness of the benefits of cold therapy for CIPN.

Topical treatment of chemotherapy-induced peripheral neuropathy (CIPN) with high-concentration (179 mg) capsaicin patch in breast cancer patients - results of the QUCIP study

Background

Chemotherapy-induced peripheral neuropathy (CIPN) following oral or intravenous chemotherapy often results in neuropathic pain, accompanied by symptoms such tingling, burning and hypersensitivity to stimuli, with a notable decline in quality of life (QoL). Effective therapies for CIPN are lacking, with a high demand for analgesics to address this issue. The QUCIP study aimed to assess the effectiveness of high concentration (179 mg) capsaicin patch (HCCP) in alleviating neuropathic pain and associated symptoms in breast cancer patients with confirmed CIPN.

Methods

QUCIP is a prospective, multi-center observational study spanning 36 weeks with up to three HCCP treatments. Initial treatment (visit V0) was followed by two telephone contacts (T1, T2) and subsequent face-to-face visits every 12 weeks or upon retreatment (visits V1-V3). 73 female patients with painful CIPN post neoadjuvant/adjuvant breast cancer therapy were enrolled. Primary endpoint was the reduction of neuropathic pain symptom score (painDETECT®). Secondary endpoints included improvements in CIPN-specific QoL (QLQ-CIPN20), reductions in pain intensity (numeric pain rating scale, NPRS), and achievement of ≥ 30% and ≥ 50% pain reduction.

Results

Median age was 61 years, with 52.0% of patients experiencing peripheral neuropathic pain for > 1 year (> 2 years: 34.2%). The painDETECT® score significantly decreased from baseline (19.71 ± 4.69) to 15.80 ± 6.20 after initial treatment (p < 0.0001) and continued to decrease at follow-up visits. The NPRS indicated significant pain intensity reduction at each time point, particularly pronounced in patients receiving three HCCP treatments. Clinically significant pain relief of ≥ 30% increased from 25.0% at week 4 (T2) to 36.2%, 43.5%, and 40.0% at weeks 12 (V1), 24 (V2), and 36 (V3), respectively. The percentage of patients achieving pain relief of ≥ 50% increased from 14.7% at T2 to 15.5%, 21.7% and 32.5% at V1, V2 and V3, respectively. Patients further reported a significant improvement in their CIPN-related QoL throughout the study. Adverse drug reactions (ADRs) mainly included application site reactions.

Conclusion

In this study, HCCP shows benefit in managing CIPN in real-world settings. The data demonstrate a sustained and progressive reduction in neuropathic pain and symptomatology, confirming the clinical benefit of repeated treatment observed in former clinical trials. HCCP treatment has also the potential to significantly improve the QoL associated with CIPN. The safety profile of HCCP was confirmed, supporting its use in clinical practice.

Global disparities in cancer supportive care: An international survey

BACKGROUND

The global cancer burden is rising, particularly in low- and middle-income countries (LMIC), highlighting a critical research gap in understanding disparities in supportive care access. To address this, the Multinational Association of Supportive Care in Cancer (MASCC) Health Disparities Committee initiated a global survey to investigate and delineate these disparities. This study aims to explore and compare supportive care access disparities between LMIC and High-Income Countries (HIC).

METHODS

An online cross-sectional survey was conducted among active members of MASCC. Members, representing diverse healthcare professions received email invitations. The survey, available for 3 weeks, comprised sections covering (1) sociodemographic information; (2) clinical service/practice-related disparities in their region/nation; (3) population groups facing disparities within their region or country. Chi-squared or Fisher's exact test for cross-sectional analyses, and a multivariable logistic regression model was employed for statistical analysis.

RESULTS

A total of 218 active members participated, with one-quarter (26.6%) from LMIC and 18.4% ethnic minorities, timely cancer care (43.7%) and timely supportive care (45.0%) emerged as the most pressing disparities globally. Notably, participants from LMIC underscored cancer drug affordability (56.4%) and supportive care guideline implementation (56.4%) as critical issues. Economically disadvantaged populations were noted as more likely to face disparities by both LMIC and HIC (non-US-based) respondents, while US-based respondents identified racial/ethnic minorities as facing more disparities.

CONCLUSION

This global survey reveals significant disparities in cancer supportive care between LMIC and HIC, with a particular emphasis on medication affordability and guideline implementation in LMIC. Addressing these disparities requires targeted intervention, considering specific regional priorities.

Efficacy of cryotherapy in the prevention of chemotherapy-induced peripheral neuropathy: A systematic review and meta-analysis

PURPOSE

The study investigates cryotherapy's efficacy in mitigating Chemotherapy-induced peripheral neuropathy (CIPN), an adverse effect of chemotherapy that often leads to dosage reduction or treatment discontinuation.

METHOD

The study was registered with PROSPERO (CRD42023428936). A literature search was conducted using the PubMed, Embase, and Cochrane Library databases. Randomized and nonrandomized controlled trials that investigated the effects of cryotherapy on CIPN were included for systematic review and meta-analysis. The primary outcome for prevention was the incidence of CIPN.

RESULTS

We identified 17 trials involving 2,851 patients. In total, 11 trials compared the incidence of CIPN between cryotherapy and control groups. Significant differences in the incidence of CIPN at the midpoint and end of chemotherapy were observed, with risk ratios (RRs) of 0.23 (95% confidence interval [CI] = 0.13 to 0.43) and 0.54 (95% CI = 0.33 to 0.88), respectively. Cryotherapy also significantly reduced the incidence of sensory CIPN, with an RR of 0.67 (95% CI = 0.49 to 0.92). Additionally, cryotherapy demonstrated a significant reduction in the incidence of CIPN in patients with gynecological cancers (RR = 0.24, 95% CI = 0.14 to 0.41). Significantly favorable global quality of life scores following chemotherapy (standardized mean difference = 1.43; 95% CI = 0.50 to 2.36) and relieved neuropathic symptoms were found with cryotherapy.

CONCLUSIONS

Cryotherapy demonstrates a pronounced preventive effect against the development of CIPN, providing substantial symptomatic relief and quality of life improvements for patients undergoing chemotherapy. The administration of cryotherapy through the use of frozen gloves and socks, or continuous-flow cooling systems, optimally initiated 15 min prior to and concluded 15 min following chemotherapy, is recommended for achieving maximum therapeutic efficacy.

Financial Toxicity in Cancer Supportive Care: An International Survey

PURPOSE

The study aims to explore unmet social needs and sources of financial toxicities in patients as noted by health care professionals and researchers in cancer supportive care, shedding light on potential health disparities.

METHODS

In this cross-sectional survey, we anonymously surveyed active members of the Multinational Association of Supportive Care in Cancer (MASCC). The survey, structured in three sections, included questions regarding the routine assessment of social needs during patient consultations, sociodemographic aspects, factors influencing financial toxicity (FT), perceived support for managing FT, and available/desirable resources.

RESULTS

A total of 218 MASCC members were included, predominantly from high-income countries (HIC, 73.4%), with many age 41-60 years (56.5%) and female (56.9%). Drug/treatment cost and insurance coverage were the main sources for FT among the HIC, whereas participants from low-middle-income countries (LMIC) considered transportation cost, loss of employment because of cancer diagnosis, and unavailability of return-to-work services as the top three sources of FT. Respondents from LMIC (adjusted odds ratio [aOR], 3.01 [95% CI, 1.15 to 7.93]) and physicians (aOR, 2.67 [95% CI, 1.15 to 6.21]) were more likely to routinely assess financial coverages. Socioeconomic status was consistently ranked as one of the top three sources of financial toxicities by participants from LMIC (34%), HIC excluding the United States (38%), those who do not self-identify as racial/ethnic minority (36%), and physicians (40%).

CONCLUSION

This global survey of health care professionals and researchers in HIC and LMIC revealed varying approaches to assessing financial coverage and social needs. Socioeconomic status emerged as a consistent concern across countries, affecting financial toxicities. The study highlights the need for tailored approaches and improved resource visibility while emphasizing clinicians' pivotal role in addressing financial aspects of cancer care.

Safety and Efficacy of Compression Therapy to Prevent Chemotherapy-Induced Peripheral Neuropathy in Lower Extremities of Breast Cancer Patients: A Pilot Study

Background Chemotherapy-induced peripheral neuropathy (CIPN) is a problematic adverse event for breast cancer patients receiving taxane antimitotic agents. We evaluated the effectiveness of compression therapy against CIPN in the lower extremities of breast cancer patients receiving taxanes. Methods Eligible patients scheduled for perioperative treatment with taxanes for early-stage breast cancer were enrolled. Each patient wore latex-free surgical gloves and compression socks, putting on two layers of each 15 minutes before the administration of taxanes and removing them 15 minutes after administration. Peripheral neuropathy (PN) was evaluated using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 and the Patient Neurotoxicity Questionnaire (PNQ). The primary endpoint was the incidence of CTCAE version 4.0 grade 2 or higher CIPN in the lower extremities during the entire period of perioperative chemotherapy with taxanes. Results PN assessment by CTCAE in the lower extremities, the primary outcome, showed that 13.3% developed grade 2 sensory disturbances, and 8.3% developed grade 2 motor disturbances. The incidence of CTCAE grade 2 or higher PN in the hands was 26.7% for sensory disturbances and 13.3% for motor disturbances during the entire study period. No patient had grade 3 or higher PN. No adverse events due to compression therapy were observed. Conclusion Compression of the lower extremities with compression socks tended to reduce the incidence of CIPN compared to the general incidence. Compression therapy may help prevent the development of CIPN.

Equity, diversity, and inclusion in the Multinational Association for Supportive Care in Cancer: a global membership survey

Equity, diversity, and inclusion (EDI) are essential for healthcare organizations since they allow for the development of programs and initiatives that bring together diverse perspectives and knowledge. Global multidisciplinary organizations, such as the Multinational Association for Supportive Care in Cancer (MASCC), need to understand the perspective of their members regarding EDI to identify opportunities to enhance diversity and inclusiveness and to better meet the needs of members from different backgrounds and resources. The MASCC Health Disparities Committee designed a survey to identify issues related to disparities faced by MASCC members when providing supportive care to patients with cancer and to examine the EDI landscape within the organization. Here, we report results related to EDI initiatives within the organization. Two-hundred and eighteen MASCC members responded to the survey (response rate 10.2%). The results indicated that respondents were generally satisfied with how MASCC manages leadership, membership, and organization-related EDI issues. Opportunities for improvement noted by respondents included developing strategies to foster a more diverse membership, improving communication regarding diversity in the organization, and increasing EDI content in educational sessions and publications. The results of this survey represent the first attempt at understanding how to improve EDI within MASCC and will be utilized to guide further initiatives and programs.

The Safety and Efficacy of Cryotherapy in the Prevention of Paclitaxel-Induced Neuropathy: A Systematic Review

The chemotherapeutic agent paclitaxel has significantly enhanced the treatment of various types of cancer. However, the quality of life of cancer patients is often impacted by the painful and dose-restrictive paclitaxel side effect known as paclitaxel-induced peripheral neuropathy (PIPN). A non-pharmacological method called cryotherapy has shown promise in alleviating PIPN-related symptoms. In this systematic review, we aimed to evaluate the safety and effectiveness of cryotherapy in preventing PIPN. The review analyzed four randomized controlled trials (RCTs) involving individuals treated with paclitaxel for breast and gynecological cancer. Cryotherapy showed success in lowering PIPN symptoms in several studies, as judged by various outcome measures, although the findings varied. The safety profile of cryotherapy was typically good, with minimal side effects. However, methodological variations and small sample sizes in the studies analyzed limit drawing definitive conclusions from them. To obtain conclusive evidence, studies with standardized techniques and larger sample sizes are required. Further research is necessary to understand cryotherapy's potential mechanisms and long-term effects. This review highlights the potential of cryotherapy in the management of PIPN, explains how it works, and suggests future research topics to improve its application.

Mitigation of paclitaxel-induced peripheral neuropathy in breast cancer patients using limb-cooling apparatus: a study protocol for a randomized controlled trial

Background

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common adverse events that can significantly impair the quality of life of patients. Although limb cooling may be beneficial for preventing CIPN, logistical challenges exist in ensuring consistent efficacy and safety. The purpose of this randomized controlled trial is to validate whether limb cooling with strict temperature control can reduce CIPN in patients with breast cancer receiving weekly paclitaxel as a perioperative treatment.

Methods

This study is a multicenter, double-blinded, randomized controlled trial. We plan to enroll patients with breast cancer who are scheduled to receive 12 weekly doses of paclitaxel (60 min 80 mg/m² intravenous infusion) as perioperative chemotherapy. Patients will be randomly divided into the intervention or control groups and undergo limb cooling therapy maintained at a constant temperature of 13°C and 25°C, respectively. The primary endpoint is the proportion of patients who report Patient Neurotoxicity Questionnaire (PNQ) ≥ D in their limbs by the end of the study treatment or at the time of discontinuation.

Discussion

The results of this trial will contribute to the establishment of new evidence for limb cooling therapy in the mitigation of CIPN and present a safe and stable cooling device that may be suitable for use in the clinic.
