Innovative Approach for the Prevention of Chemotherapy-Induced Peripheral Neuropathy in Cancer Patients: A Pilot Study With the Hilotherm Device, the Poliambulanza Hospital Experience

Cryotherapy for prevention of chemotherapy induced peripheral neuropathy in breast cancer

Peripheral neuropathy is a well-described complication of chemotherapy. There are no known treatments to reverse peripheral neuropathy. Chemotherapy-induced peripheral neuropathy is a dose-limiting toxicity in cancer treatment and is debilitating. Cryotherapy, or the use of cold garments/ice bags applied to extremities during chemotherapy, is a method to prevent or minimize treatment related neuropathy. There is no standard method of providing cryotherapy currently. A review of the literature was performed revealing that a variety of cryotherapy methods exist. While small studies suggest potential preventive effect of some forms of cryotherapy, consistent results from well-designed randomized studies are lacking. A small benefit from the use of cryotherapy to prevent peripheral neuropathy might exist, but conflicting studies exist. In light of the low cost to implement ice bags during chemotherapy and the low risk of toxicity, the use of ice bags may be reasonable during taxane chemotherapy for the treatment of breast cancer.

Chemotherapy-induced peripheral neuropathy in children and adolescent cancer patients

Brain cancer and leukemia are the most common cancers diagnosed in the pediatric population and are often treated with lifesaving chemotherapy. However, chemotherapy causes severe adverse effects and chemotherapy-induced peripheral neuropathy (CIPN) is a major dose-limiting and debilitating side effect. CIPN can greatly impair quality of life and increases morbidity of pediatric patients with cancer, with the accompanying symptoms frequently remaining underdiagnosed. Little is known about the incidence of CIPN, its impact on the pediatric population, and the underlying pathophysiological mechanisms, as most existing information stems from studies in animal models or adult cancer patients. Herein, we aim to provide an understanding of CIPN in the pediatric population and focus on the 6 main substance groups that frequently cause CIPN, namely the vinca alkaloids (vincristine), platinum-based antineoplastics (cisplatin, carboplatin and oxaliplatin), taxanes (paclitaxel and docetaxel), epothilones (ixabepilone), proteasome inhibitors (bortezomib) and immunomodulatory drugs (thalidomide). We discuss the clinical manifestations, assessments and diagnostic tools, as well as risk factors, pathophysiological processes and current pharmacological and non-pharmacological approaches for the prevention and treatment of CIPN.

Preventing taxane-related peripheral neuropathy, pain and nail toxicity: a prospective self-controlled trial comparing hilotherapy with frozen gloves in early breast cancer

PURPOSE

The prevention of taxane-related toxicities at the extremities is highly important for patients' treatment and quality-of-life. Several studies endorse hand/foot-cooling using frozen gloves as a prophylactic intervention. Unlike frozen gloves, hilotherapy produces cooling at a constant temperature. Comparative data with frozen gloves are unavailable.

METHODS

This prospective self-controlled study explores the efficacy of hilotherapy at the right hand and foot compared to frozen gloves at the left in patients with early breast cancer treated with weekly paclitaxel 80 mg/m² or three-weekly docetaxel 75 mg/m². Patient-reported outcomes were collected at baseline, 6, 12, 18 and 24 weeks after the start of treatment. Primary and secondary endpoints were the incidence of any-grade and ≥ grade 2 side-effects (peripheral neuropathy, pain and nail toxicities), and perceived comfort of both interventions.

RESULTS

Sixty-two patients participated. The incidence of any-grade side-effects was similar on both sides, 85.5% with hilotherapy and 90.3% with frozen gloves (p = 1.000). The incidence of ≥ grade 2 side-effects at the extremities was significantly lower with hilotherapy: 43.6% compared to 61.3% with frozen gloves (p = 0.013). Perceived comfort was significantly better for hilotherapy than for frozen gloves (p < 0.0001).

CONCLUSIONS

Compared to frozen gloves, continuous cooling of hands and feet using hilotherapy produces better prevention of ≥ grade 2 patient-reported side-effects at the extremities (peripheral neuropathy, pain and nail toxicities). Perceived comfort was significantly better for hilotherapy. From a clinical and patient perspective, hilotherapy is a better alternative for preventing clinically significant taxane-related side-effects.

Drug-Induced Peripheral Neuropathy: Diagnosis and Management

Peripheral neuropathy comes in all shapes and forms and is a disorder which is found in the peripheral nervous system. It can have an acute or chronic onset depending on the multitude of pathophysiologic mechanisms involving different parts of nerve fibers. A systematic approach is highly beneficial when it comes to cost-effective diagnosis. More than 30 causes of peripheral neuropathy exist ranging from systemic and auto-immune diseases, vitamin deficiencies, viral infections, diabetes, etc. One of the major causes of peripheral neuropathy is drug induced disease, which can be split into peripheral neuropathy caused by chemotherapy or by other medications. This review deals with the latest causes of drug induced peripheral neuropathy, the population involved, the findings on physical examination and various workups needed and how to manage each case.

Chemotherapy-induced neurotoxicity in the treatment of gynecological cancers: State of art and an innovative approach for prevention

Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect that occurs in 20% of ovarian cancer patients treated with the combination of carboplatin/paclitaxel (CP). This toxicity is directly correlated with the dose of paclitaxel administered. Several studies have investigated whether different formulations of taxane can induce this side effect at a lower rate, but, unfortunately, no significant improvement was obtained. CIPN can be disabling in the daily lives of patients and can cause dose reduction or early termination of the treatment. Neuropathy can last for months and even years after its onset. Moreover, patients responsive to CP treatment are candidates for a reintroduction of the same drugs when disease relapse occurs, and residual neuropathy can affect the continuation of treatment. There are no approved drugs that mitigate or prevent the onset of CIPN. In this review, we summarize the evidence regarding the incidence of CIPN with different taxane formulations, regimen schedules and prevention systems. In particular, the Hilotherm^® Chemo care device is a regional cooling system that lowers the temperature of the hands and feet to reduce the flow of chemotherapy into the capillaries. We used hilotherapy during chemotherapy infusion to prevent the onset of CIPN. Updated data from 44 ovarian cancer patients treated with 6 cycle of CP show that hilotherapy was well tolerated; only two patients (4.5%) stopped hilotherapy because of cold intolerance, and only one patient (2.2%) experienced grade ≥ 2 CIPN.

The Impact of AC and AC-T Chemotherapy's Toxicities on Quality of Life Among Women with Breast Cancer in Ethiopia: A Prospective Patient-Reported Outcomes Study

PURPOSE

The study aimed to evaluate the quality of life patterns and the effects of AC and AC-T chemotherapy's toxicities on QoL among Ethiopian women with breast cancer.

METHODS

QoL was measured at baseline and at every end of two cycles, for the median of 8 cycles among 146 breast cancer women on AC and AC-T chemotherapy, using EORTC QLQ-C30 and BR23 instruments. The effect of QoL score, socio-demographic, and clinical variables at baseline were adjusted for the effect of chemotherapy's toxicities on QoL.

RESULTS

Overall QoL, all functional scales (except cognitive functioning, body image, future perspectives, and sexual functioning) and symptom scales (except dyspnea, insomnia, pain score, arm, and breast symptoms) of EORTC QLQ-C30 and BR23 deteriorated significantly both clinically and statistically, in particular, during the first two cycles of chemotherapy. After the end of cycle 2 or 4, except for cognitive, social functioning, and financial difficulties of the patients, almost all other QoL dimensions were improved towards pretreatment score by the end of cycle 8. In addition to age, educational status, and tumor stage, the Global Health Status (-10.55≤B≤-7.71, P≤0.013), and the functional scales (-25.320≤B≤-6.351, P≤0.033) of EORTC QLQ-C30 and BR23 were significantly affected at least by one of the AC and AC-T chemotherapy's toxicity such as grade≥2 fatigue, dysgeusia, constipation, dry mouth, vomiting, oral mucositis, skin hyperpigmentation and/or peripheral neuropathy than their lower grade. Grade≥2 fatigue, dysgeusia, oral mucositis, constipation, peripheral neuropathy, anemia arthralgia/myalgia, dry mouth, diarrhea, constipation, and/or skin hyperpigmentation were positively predicted for the deterioration of symptoms scale of EORTC QLQ-C30 and BR23 (4.819≤B≤26.451, P≤0.043).

CONCLUSION

Quality of life among Ethiopian breast cancer patients on AC and AC-T regimens significantly deteriorated particularly during the first two cycles of chemotherapy. In addition to the age, tumor stage and educational status of the patients, grade≥2 fatigue, dysgeusia, constipation, oral mucositis, dry mouth, peripheral neuropathy, and skin hyperpigmentation due to AC and AC-T chemotherapy were frequently associated with deterioration of different scales/items QoL. Hence, devising different strategies to improve the deteriorated QoL due to chemotherapy's toxicities particularly during the first two cycles has paramount importance.

Human Intravenous Immunoglobulin Alleviates Neuropathic Symptoms in a Rat Model of Paclitaxel-Induced Peripheral Neurotoxicity

The onset of chemotherapy-induced peripheral neurotoxicity (CIPN) is a leading cause of the dose reduction or discontinuation of cancer treatment due to sensory symptoms. Paclitaxel (PTX) can cause painful peripheral neuropathy, with a negative impact on cancer survivors' quality of life. While recent studies have shown that neuroinflammation is involved in PTX-induced peripheral neurotoxicity (PIPN), the pathophysiology of this disabling side effect remains largely unclear and no effective therapies are available. Therefore, here we investigated the effects of human intravenous immunoglobulin (IVIg) on a PIPN rat model. PTX-treated rats showed mechanical allodynia and neurophysiological alterations consistent with a severe sensory axonal polyneuropathy. In addition, morphological evaluation showed a reduction of intra-epidermal nerve fiber (IENF) density and evidenced axonopathy with macrophage infiltration, which was more prominent in the distal segment of caudal nerves. Three weeks after the last PTX injection, mechanical allodynia was still present in PTX-treated rats, while the full recovery in the group of animals co-treated with IVIg was observed. At the pathological level, this behavioral result was paralleled by prevention of the reduction in IENF density induced by PTX in IVIg co-treated rats. These results suggest that the immunomodulating effect of IVIg co-treatment can alleviate PIPN neurotoxic manifestations, probably through a partial reduction of neuroinflammation.
