A randomized controlled trial of hand/foot-cooling by hilotherapy to prevent oxaliplatin-related peripheral neuropathy in patients with malignancies of the digestive system.

ABSTRACT:

Background

Both acute and chronic symptoms of oxaliplatin-induced peripheral neuropathy (OIPN) affect patients' treatment dose and duration as well as quality-of-life. Hand/foot-cooling has been shown to reduce taxane-induced peripheral neuropathy but there is unclear evidence in the setting of oxaliplatin.

Patients and methods

In a monocentric, open-label phase II trial, patients with malignancies of the digestive system receiving oxaliplatin-based chemotherapy were randomly assigned to receive either continuous cooling of hands and feet using hilotherapy at 11°C during oxaliplatin infusion compared with usual care (no cooling). The primary endpoint was grade ≥2 neuropathy-free rate in 12 weeks after initiation of chemotherapy. Secondary endpoints included OIPN-related treatment alterations, acute OIPN symptoms and perceived comfort of the intervention.

Results

The intention-to-treat population included 39 patients in the hilotherapy group and 38 in the control group. The grade ≥2 neuropathy-free rate at 12 weeks was 100% in the experimental group versus 80.5% in the control group (P = 0.006). This effect was persistent at 24 weeks (66.0% versus 49.2%, respectively) (P = 0.039). Next, treatment alterations-free rate at week 12 was 93.5% in the hilotherapy group compared with 83.3% in the control group (P = 0.131). Patients in the hilotherapy group experienced significantly less acute OIPN symptoms of numbness or tingling [odds ratio (OR) 0.05, 95% confidence interval (CI) 0.02-0.11, P < 0.0001], pain (OR 0.06, 95% CI 0.02-0.15, P < 0.0001) and/or cold sensitivity (OR 0.02, 95% CI 0.01-0.05, P < 0.0001) in fingers or toes as well as less pharyngeal cold sensitivity (OR 0.14, 95% CI 0.05-0.42, P = 0.0005). The majority of patients in the hilotherapy group rated the intervention as neutral, rather comfortable or very comfortable.

Conclusions

In this first study on hand/foot-cooling in oxaliplatin alone, hilotherapy significantly reduced the incidence of grade ≥2 OIPN at 12 and 24 weeks. Hilotherapy also reduced acute OIPN symptoms and was generally well tolerated.

Project description:Oxaliplatin-induced peripheral neurotoxicity (OIPN) is a debilitating side effect that afflicts ~90% of patients that is initiated by OCT2-dependent uptake of oxaliplatin in DRG neurons. The antidepressant drug duloxetine has been used to treat OIPN, although its usefulness in preventing this side effect remains unclear. We hypothesized that duloxetine has OCT2-inhibitory properties and can be used as an adjunct to oxaliplatin-based regimens to prevent OIPN. Transport studies were performed in cells stably transfected with mouse or human OCT2 and in isolated mouse DRG neurons ex vivo. Wild-type and OCT2-deficient mice were used to assess effects of duloxetine on hallmarks of OIPN, endogenous OCT2 biomarkers, and the pharmacokinetics of oxaliplatin, and the translational feasibility of a duloxetine-oxaliplatin combination was evaluated in various models of colorectal cancer. We found that duloxetine potently inhibited the OCT2-mediated transport of several xenobiotic substrates, including oxaliplatin, in a reversible, concentration-dependent manner, and independent of species and cell context. Furthermore, duloxetine restricted access of these substrates to DRG neurons ex vivo and prevented OIPN in wild-type mice to a degree similar to the complete protection observed in OCT2-deficient mice, without affecting the plasma levels of oxaliplatin. Importantly, the uptake and cytotoxicity of oxaliplatin in tumor cell lines in vitro and in vivo were not negatively influenced by duloxetine. The observed OCT2-targeting properties of duloxetine, combined with the potential for clinical translation, provide support for its further exploration as a therapeutic candidate for studies aimed at preventing OIPN in cancer patients requiring treatment with oxaliplatin.SignificanceWe found that duloxetine has potent OCT2-inhibitory properties and can diminish excessive accumulation of oxaliplatin into DRG neurons. In addition, pre-treatment of mice with duloxetine prevented OIPN without significantly altering the plasma pharmacokinetics and antitumor properties of oxaliplatin. These results suggest that intentional inhibition of OCT2-mediated transport by duloxetine can be employed as a prevention strategy to ameliorate OIPN without compromising the effectiveness of oxaliplatin-based treatment.

Project description:BackgroundOxaliplatin-induced peripheral neurotoxicity (OIPN) limits the dose of chemotherapy and seriously affects the quality of life. Huangqi Guizhi Wuwu Decoction (HGWD) is a classical Traditional Chinese Medicine (TCM) formula for the prevention of OIPN. However, its specific pharmacological mechanism of action remains unknown. Our study found that HGWD can effectively alleviate chronic OIPN and regulate intestinal flora. Therefore, we explored the mechanism of action of HGWD in alleviating chronic OIPN from the perspective of intestinal flora.MethodsIn this study, we established an OIPN model in C57BL/6 mice treated with different concentrations of HGWD. Mechanical pain and cold pain were assessed at certain time points, and samples of mice colon, dorsal root ganglion (DRG), serum, and feces were collected. Associated inflammation levels in the colon and DRG were detected using immunohistochemical techniques; the serum lipopolysaccharide (LPS) levels and associated inflammation were assessed using the appropriate kits; and 16S rRNA sequencing was used to examine the dynamic changes in gut microorganisms. Finally, established fecal microbiota transplantation (FMT) and antibiotic (ABX) pretreatment models were used to validate flora's role in HGWD for chronic OIPN by pain scoring and related pathological analysis.ResultsHGWD treatment significantly alleviated pain sensitivity in chronic OIPN mice. Pathological results showed that HGWD treatment improved intestinal ZO-1 expression and reduced serum LPS levels and associated inflammatory factors in the colon, serum, and DRG. The 16S rRNA results showed that HGWD restored the composition of the intestinal flora in a time-dependent manner to alleviate OIPN. FMT and ABX experiments demonstrated that HGWD can alleviate chronic OIPN by regulating intestinal flora homeostasis.ConclusionsHGWD prevents chronic OIPN by dynamically regulating intestinal flora homeostasis, thereby ameliorating intestinal barrier damage and reducing serum LPS and relevant inflammatory factor levels in the colon, serum, and DRG.

Project description:ObjectivesTo assess the clinical evidence for integrative herbal medicine therapy in the management of chemotherapy-induced peripheral neuropathy (CIPN) and hand-foot syndrome (HFS) resulting from treatments for colorectal cancer (CRC).DesignRandomized controlled trials (RCTs) were identified from major English and Chinese databases. Participants had been diagnosed with CRC by pathology and had received or were undergoing chemotherapy. Interventions included herbal medicines administered orally or topically. Controls were placebo, supportive care or conventional chemotherapy for CRC. Methods followed the Cochrane handbook. Meta-analyses were grouped by study design, outcome measure, severity, and chemotherapy. Random-effects models with 95% confidence intervals were used. Heterogeneity was assessed as I2.ResultsSixty-three RCTs (4286 participants) were included. Five used a placebo in the control groups. Fifty-eight studies tested oral herbal medicine, and 5 tested topical herbal medicine. Data were available for CIPN (60 studies) and HFS (12 studies). Fifty-seven studies combined orally administered herbal medicine with chemotherapy compared with the same chemotherapy. For CIPN, 33 studies used World Health Organization (WHO) criteria, 7 used Levi's criteria, and 10 used the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE). These were analyzed separately. For grades III + IV CIPN, there was a significant reduction in the integrative groups for WHO (relative risk [RR] 0.42 [0.23, 0.77], I2 = 0%) and Levi's (RR 0.28 [0.11, 0.69], I2 = 0%) but not NCI-CTCAE (RR 0.65 [0.37, 1.13], I2 = 26.4%). Hand and foot baths showed no differences for Levi's grades III + IV CIPN but a significant reduction in all grades (RR 0.69 [0.50, 0.95], I2 = 68.8%). For HFS (all grades) there was a significant reduction in the integrative groups for WHO (RR 0.62 [0.41, 0.96], I2 = 22%) but not for NCI-CTCAE (RR 0.93 [0.55, 1.55], I2 = 75.7%). Sensitivity analyses explored sources of heterogeneity.ConclusionsIntegrative herbal therapy appeared to reduce CIPN and HFS in people receiving chemotherapy for CRC. However, the strength of the evidence was limited by lack of blinding in most studies, potential for bias, and relatively short study durations.
