Predictors of Hand-Foot Syndrome and Pyridoxine for Prevention of Capecitabine-Induced Hand-Foot Syndrome: A Randomized Clinical Trial

Topical Diclofenac for Prevention of Capecitabine-Associated Hand-Foot Syndrome: A Double-Blind Randomized Controlled Trial

PURPOSE

Hand-foot syndrome (HFS) is a dose-limiting side effect of capecitabine. Celecoxib prevents HFS by inhibiting cyclooxygenase-2 (COX-2) that is upregulated because of the underlying associated inflammation. However, systemic side effects of celecoxib have limited routine prescription. Topical diclofenac inhibits COX-2 locally with minimal risk of systemic adverse events. Therefore, we conducted this study to assess the efficacy of topical diclofenac in the prevention of capecitabine-induced HFS.

METHODS

In this single-site phase III randomized double-blind trial, we enrolled patients with breast or GI cancer who were planned to receive capecitabine-based treatment. Participants were randomly assigned in a 1:1 ratio to receive topical diclofenac or placebo gel for 12 weeks or until the development of HFS, whichever occurred earlier. The primary end point was the incidence of grade 2 or 3 HFS (Common Terminology Criteria for Adverse Events version 5), which was compared between the two groups using simple logistic regression.

RESULTS

In total, 264 patients were randomly assigned to receive topical diclofenac gel (n = 131) or placebo (n = 133). Grade 2 or 3 HFS was observed in 3.8% of participants in the diclofenac group compared with 15.0% in the placebo group (absolute difference, 11.2%; 95% CI, 4.3 to 18.1; P = .003). Grade 1-3 HFS was lower in the diclofenac group than in the placebo group (6.1% v 18.1%; absolute risk difference, 11.9%; 95% CI, 4.1 to 19.6). Capecitabine dose reductions because of HFS were less frequent in the diclofenac group (3.8%) than in the placebo group (13.5%; absolute risk difference, 9.7%; 95% CI, 3.0 to 16.4).

CONCLUSION

Topical diclofenac prevented HFS in patients receiving capecitabine. This trial supports the use of topical diclofenac to prevent capecitabine-associated HFS.

Hand-foot syndrome in cancer patients on capecitabine: examining prevalence, impacts, and associated risk factors at a cancer centre in Malaysia

INTRODUCTION

Hand-foot syndrome (HFS) significantly impacts quality of life in cancer patients undergoing capecitabine treatment. This study assessed capecitabine-associated HFS prevalence, its impacts on chemotherapy treatment, and identified risk factors in multiracial Malaysian patients.

METHODS

We included adult cancer patients receiving capecitabine at Sarawak General Hospital for at least two cycles from April 1, 2021 to June 30, 2022. HFS rates, time to HFS, and proportions of HFS-related treatment modifications were determined. Characteristics between patients with and without HFS were compared and multivariable logistic regression was used to identify risk factors for all-grade HFS and grade ≥2.

RESULTS

Among 369 patients, 185 (50.1%) developed HFS, with 14.6% experiencing grade ≥2 and 21.6% (40/185) underwent treatment modifications. Risk factors for all-grade HFS include older age (OR 1.03 95%CI 1.01, 1.06), prior chemotherapy (OR 2.09 95%CI 1.22, 3.58), higher capecitabine dose (OR 2.96 95%CI 1.62, 5.38), prolonged treatment (OR 1.36 95%CI 1.21, 1.51), folic acid intake (OR 3.27 95%CI 1.45, 7.35) and lower neutrophil count (OR 0.77 95%CI 0.66, 0.89). For HFS grade ≥2, older age (OR 1.04 95%CI 1.01, 1.08), female sex (OR 2.10 95%CI 1.05, 4.18), Chinese race (OR 2.10 95%CI 1.06, 4.18), and higher capecitabine dose (OR 2.62 95%CI 1.28, 5.35) are significant risk factors. Use of calcium channel blockers were associated with reduced risks of all-grade HFS (OR 0.27, 95%CI 0.12, 0.60) and grade ≥2 (OR 0.21 95%CI 0.06, 0.78).

CONCLUSION

This study provides real-world data on capecitabine-induced HFS in Malaysian patients and identifies risk factors that may offer insights into its understanding and management.

Safety and efficacy of vitamin B in cancer treatments: A systematic review

BACKGROUND

With rising rates of complementary and alternative medicine use, the exploration of complementary and alternative medicine integration into oncology treatments is becoming increasingly prevalent. Vitamin B compounds including B1, B2, B3, B5, B6, B9, and B12, have all been proposed as potentially beneficial in cancer prevention and treatment as well as side effect management; however, many studies contain contradicting evidence regarding the utility of B vitamins within oncology. Thus, the aim of this study was to evaluate the safety and efficacy of Vitamin B supplementation in the oncology setting.

DESIGN

A systematic review was conducted following The Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Reviews guidelines, using pre-specified search terms in PubMed to include randomized control trials, clinical trials, and case studies. Two reviewers independently reviewed titles, abstracts, and full-text articles for inclusion, with a third reviewer resolving conflicts, before the included articles underwent data extraction and quality appraisal. Data extraction was conducted through COVIDENCE, which was used to manage and track the data during the search process.

RESULTS

Out of 694 articles initially identified, 25 articles met the inclusion criteria and were included in the review. Designs of the studies varied, including randomized control trials, clinical trials, and case/cohort studies. The impact of vitamin supplementation on cancer risk varied. Several studies found that certain B vitamin supplementation lowered cancer risk: B9 and B6 in nasopharyngeal carcinoma (n  =  1200 patients) and in pancreatic cancer (n  =  258 patients); B3 in hepatocellular carcinoma (n  =  494,860 patients); B6 in breast cancer (n  =  27,853 patients); and B9 in BRCA1-positive breast cancer (n  =  400 patients). However, some studies found that certain B vitamin supplementation increased the risk or negative outcomes of cancer: B6 during nasopharyngeal carcinoma treatment (n  =  592 patients); B6 in risk of hepatocellular carcinoma (n  =  494,860 patients); and B9 plasma levels in breast cancer (n  =  164 patients). Due to the many adverse effects that occur in cancer treatment, the effectiveness of Vitamin B supplementation in alleviating adverse effects was evaluated. In two separate studies, Vitamin B6 and Vitamin B12 supplementation with acupuncture was found to be effective as adjunct therapies aimed to reduce chemotherapy-induced peripheral neuropathy (n  =  23 patients and n  =  104 patients, respectively). No significant findings were established regarding B vitamin supplementation in chemotherapy-induced hand-foot syndrome.

CONCLUSIONS

In this systematic review we concluded that B vitamin supplements have varying data regarding safety and efficacy in cancer. Taking into account the etiology of the cancer, the specific B-vitamin, and the presence of any side effects could help guide utilization of the data found in this review. Large, randomized controlled trials are needed to confirm these findings among various cancer diagnoses and stages. Given the widespread utilization of supplements, healthcare providers should understand the safety and efficacy of vitamin B supplementation to address questions that arise in caring for those with cancer.

Predictive factors for the development of capecitabine-induced hand-foot syndrome: a retrospective observational cohort study

Background

Capecitabine-induced hand-foot syndrome (HFS) is a common condition that significantly affects patients' quality of life. The exact underlying mechanisms are currently not clearly understood. Therefore, the study of predictive factors for HFS is of critical importance.

Materials and methods

This prognostic factor research used a retrospective observational cohort as the study design. Data collected from the medical records of 205 patients treated with capecitabine between January 2019 and June 2022 were subjected to univariable and multivariable regression analysis to determine the predictive factors for the development of grade 2 and grade 3 HFS.

Results

The incidence of grade 2 and grade 3 HFS was 26.8%. The independent predictive factors, such as age over 60 years (OR 4.80, 95% CI: 2.16-10.68, P<0.001), capecitabine dose greater than 3000 mg/day (OR 2.47, 95% CI: 1.09-5.59, P=0.030), and the number of cycles five or more in the total capecitabine regimen (OR 2.94, 95% CI: 1.29-6.71, P=0.01), were significantly associated with the development of grade 2 and grade 3 HFS.

Conclusions

Independent predictive factors for the development of grade 2 and grade 3 HFS in patients treated with capecitabine include age over 60, capecitabine dose greater than 3000 mg/day, and patients who plan to undergo five or more cycles in the total capecitabine regimen. This knowledge can be valuable for guiding clinical monitoring and follow-up of patients.

Topical interventions for preventing hand-foot syndrome resulting from antineoplastic therapy: A scoping review

OBJECTIVE

To map topical interventions used to prevent hand-foot syndrome in cancer patients undergoing antineoplastic therapy.

METHOD

This is a scoping review reported in accordance with the recommendations of PRISMA-ScR (extension for scoping review) and the Joanna Briggs Institute Manual. The searches were carried out in the electronic databases CINAHL, Cochrane CENTRAL, EMBASE, LILACS, LIVIVO, PubMed, Scopus, Web of Science; and gray literature (Google Scholar, Pro-Quest).

RESULTS

The searches resulted in 12,016 references and the final sample consisted of 45 studies. A total of 42 topical interventions were identified, including: moisturizing creams, corticosteroids, acids, mapisal, silymarin, and henna. However, urea was the most cited intervention (62%). As for the presentations of the interventions, they varied among creams, ointments, gels, hydrocolloids, decoctions, patches, powders, oils, and soaps.

CONCLUSION

The results allowed reviewing topical interventions, with emphasis on the use of urea and moisturizing creams. However, most of the interventions identified in this review require evaluation in future studies for better understanding of their benefits.

Folate, folic acid, and chemotherapy-induced toxicities: a systematic literature review

Folate metabolism is a target for various chemotherapeutic drugs. Folate and its synthetic variant folic acid are B-vitamins. To what extent these vitamins impact treatment tolerance in patients with cancer remains unclear. A systematic literature review was conducted on intake and status of folate and folic acid in relation to chemotherapy-induced toxicities in children and adults with cancer. A total of 6,231 publications were identified, of which 40 publications met the inclusion criteria. In 12 out of 22 studies focusing on antifolates, a deficient folate status and lower folate and folic acid intake were associated with a higher risk of toxicities. In 8 out of 14 studies focusing on fluoropyrimidine treatments, a higher folate status and intake were associated with a higher risk of toxicities. These findings might explain interindividual differences in treatment tolerance and highlight the importance of evaluating nutritional status in oncology care.

Pharmacogenomic-guided dosing of fluoropyrimidines beyond DPYD: time for a polygenic algorithm?

Fluoropyrimidines are chemotherapeutic agents widely used for the treatment of various solid tumors. Commonly prescribed FPs include 5-fluorouracil (5-FU) and its oral prodrugs capecitabine (CAP) and tegafur. Bioconversion of 5-FU prodrugs to 5-FU and subsequent metabolic activation of 5-FU are required for the formation of fluorodeoxyuridine triphosphate (FdUTP) and fluorouridine triphosphate, the active nucleotides through which 5-FU exerts its antimetabolite actions. A significant proportion of FP-treated patients develop severe or life-threatening, even fatal, toxicity. It is well known that FP-induced toxicity is governed by genetic factors, with dihydropyrimidine dehydrogenase (DPYD), the rate limiting enzyme in 5-FU catabolism, being currently the cornerstone of FP pharmacogenomics. DPYD-based dosing guidelines exist to guide FP chemotherapy suggesting significant dose reductions in DPYD defective patients. Accumulated evidence shows that additional variations in other genes implicated in FP pharmacokinetics and pharmacodynamics increase risk for FP toxicity, therefore taking into account more gene variations in FP dosing guidelines holds promise to improve FP pharmacotherapy. In this review we describe the current knowledge on pharmacogenomics of FP-related genes, beyond DPYD, focusing on FP toxicity risk and genetic effects on FP dose reductions. We propose that in the future, FP dosing guidelines may be expanded to include a broader ethnicity-based genetic panel as well as gene*gene and gender*gene interactions towards safer FP prescription.

Prevalence of hand-foot syndrome following chemotherapy for colorectal cancer: a systematic review and meta-analysis

OBJECTIVE

To systematically evaluate the prevalence of hand-foot syndrome (HFS) in patients with colorectal cancer undergoing chemotherapy.

METHODS

The PubMed, Embase, and Cochrane Library databases were searched, from their inception to September 20, 2022, to identify studies on the prevalence of HFS in patients with colorectal cancer receiving chemotherapy. Comprehensive retrieval of literature was performed using the literature tracing method. We calculated the prevalence of HFS in patients with colorectal cancer undergoing chemotherapy based on meta-analyses. Subgroup analysis and meta-regression analyses were performed to determine the sources of heterogeneity.

RESULTS

A total of 20 studies were included, involving 4773 cases. Meta-analysis of the random effects model showed that the total prevalence of HFS in patients with colorectal cancer undergoing chemotherapy was 49.1% (95% confidence interval [CI]: 0.332, 0.651). Subgroup analysis demonstrated that the most frequent grades of HFS were grades 1 and 2, accounting for 40.1% (95% CI: 0.285, 0.523) of cases; this rate was markedly higher than that of grades 3 and 4 (5.8%; 95% CI: 0.020, 0.112). The meta-regression results illustrated that the type of research, country of the study population, type of drug, and year of publication were not sources of heterogeneity in this setting (P > 0.05).

CONCLUSION

The present findings showed that the prevalence of HFS in patients with colorectal cancer receiving chemotherapy was high. Healthcare professionals should provide knowledge to such patients regarding the prevention and management of HFS.

Chemotherapy-induced hand foot syndrome: comparative efficacy and safety of pharmacological prophylaxis - systematic review and Bayesian network meta-analysis

BACKGROUND

Hand-foot syndrome (HFS) is one of the most common toxicities experienced by patients receiving systemic chemotherapy agents such as capecitabine and multikinase inhibitors such as sorafenib. Several randomised controlled trials (RCTs) have investigated the efficacy and safety of prophylactic agents such as pyridoxine, celecoxib, urea cream and cystine/theanine in managing HFS. This network meta-analysis (NMA) evaluated data from high-quality trials to provide strong evidence in forming recommendations to prevent systemic cancer therapy-induced HFS.

OBJECTIVE

To examine the comparative efficacy and safety of interventions for preventing systemic chemotherapy-induced HFS in patients with cancer.

METHODS

We searched PubMed, Embase and clinical trial registry for RCTs of interventions for preventing HFS. Bayesian NMA was performed to estimate the OR with 95% credible intervals (CrI) from both direct and indirect evidence. The outcome measures were the incidence of HFS (grade ≥1) and moderate to severe HFS (grade ≥2). Adverse drug reactions were discussed descriptively.

RESULTS

A total of 15 RCTs with 2715 patients with 12 prophylactic strategies were included. The analysis showed only celecoxib could significantly prevent the incidence of moderate to severe HFS (grade ≥2) (OR 0.29, 95% CrI 0.13 to 0.68). But none of the preventive interventions could prevent the incidence of HFS (grade ≥1).

CONCLUSION

Only celecoxib (200 mg two times per day) showed significant prevention of the incidence of moderate to severe HFS. Pyridoxine (400 mg once daily) and urea cream (10%) have to be evaluated further in larger randomised trials.

Pyridoxine Is Effective for Preventing Hand-Foot Syndrome Induced by Pegylated Liposomal Doxorubicin for Multiple Myeloma: The Results of a Randomized Study

PURPOSE

Pegylated liposomal doxorubicin (PLD) is highly effective for treating multiple myeloma (MM). Hand-foot syndrome (HFS) is a dose-limiting adverse event of PLD that may reduce a patient's quality of life or prevent certain patients from receiving PLD. Several researchers have discovered that pyridoxine, an activated form of vitamin B6, may prevent PLD-associated HFS. We designed a prospective randomized trial to examine whether prophylactic pyridoxine might prevent the incidence or delay the occurrence of PLD-induced HFS in patients with MM.

METHODS

Patients who met the trial's eligibility requirements were randomized and then administered either pyridoxine 100 mg twice daily or no pyridoxine, in both cases accompanied by their PLD-containing chemotherapeutic agent. Follow-up of patients was performed until the completion of induction therapy, the development of HFS or disease progression.

RESULTS

Between January 1, 2017, and January 1, 2019, 105 patients were randomly assigned to the pyridoxine group (n = 52) or the no pyridoxine group (n = 53). In the pyridoxine and no pyridoxine groups, HFS developed after a median of 4 (range, 1-8 cycles) and 3 (range, 1-7 cycles) chemotherapeutic cycles, respectively. There were no grade 3 incidents recorded. Overall, 13.3% of patients experienced HFS. A 11 of 53 (20.8%) patients in the no pyridoxine group experienced HFS, compared to 3 of 52 (5.8%) patients in the pyridoxine group (P = .042); there was no difference in HFS grades (P = .725).

CONCLUSIONS

The findings of benefit from prophylactic pyridoxine in this open-label trial have suggested its promise as a treatment for reducing HFS in MM patients. Further research with a placebo-controlled design is recommended.

Temozolomide in aggressive pituitary tumours and pituitary carcinomas

Survival for patients with aggressive pituitary tumours (APT) and pituitary carcinomas (PC) has significantly improved following the increasing use of temozolomide (TMZ) since the first reports of response in 2006. TMZ was established as first line chemotherapy for APT/PC in the 2018 ESE guidelines on the management of APT/PC. There is no controversy over its use as salvage therapy however there is increasing interest in exploring TMZ use earlier in the treatment algorithm for APT/PC. Overall response rates as reported in systematic reviews are around 40% but stable disease in another 25% illustrates the clinical effectiveness of TMZ. Response is higher among functional compared to non-functional tumours. Where maximal radiation thresholds have not been reached in a patient, combination radiotherapy and TMZ appears more effective. Whether combination TMZ and capecitabine (CAPTEM) offers increased benefit remains uncertain particularly given added toxicity. O6-methyl guanine DNA methyl transferase (MGMT) status is important in determining response to treatment, although examination via immunohistochemistry versus PCR-based promoter-methylation analysis remains somewhat controversial. Optimal duration of TMZ treatment has still not been determined although longer treatment courses have been associated with increased progression-free survival. Treatment options following disease progression after TMZ remain unclear but include a second course of TMZ, immunotherapy and targeted oncological agents such as bevacizumab and lapatinib as well as peptide receptor radionuclide treatment (PRRT). An experienced pituitary multidisciplinary team is essential to all management decisions in patients with APT/PC.

Concomitant Administration of Capecitabine and Folate Supplements: Need to Encourage Medication Reconciliation

Hand-Foot syndrome (HFS) and diarrhoea are dose-limiting Adverse Drug Reactions (ADRs) of capecitabine-based chemotherapy. Four polymorphisms in the dihydropyrimidine dehydrogenase (DPYD) gene, encoding the DPD enzyme responsible for the metabolism of fluoropyrimidines, such as capecitabine, are strongly associated with severe ADRs, and their screening should be performed before starting treatment. Moreover, capecitabine-related toxicity may worsen due to drug-drug and drug-supplement interactions. Here we investigated factors responsible for severe HFS and diarrhoea presented by two patients, non-carriers of the recommended DPYD single nucleotide polymorphisms (SNPs) but carriers of other genetic variants suggested to increase the risk of capecitabine-related ADRs. Through careful therapy recognition, we demonstrated that, unbeknownst to the oncologists, the patients were taking folic acid during the treatment with capecitabine at a dosage higher than 2000 mg/m2, which is the maximum tolerated dose when folate is administered. To resolve the ADRs, the therapy had to be drastically changed. In one case, dose reduction of capecitabine and discontinuation of lipid-lowering agents were carried out. In the other case, discontinuation of capecitabine and folic acid and capecitabine re-administration were performed after a month. Genetic and environmental factors should be considered good predictors of severe capecitabine-related toxicity. Medication reconciliation should be encouraged to avoid the harmful consequences of inappropriate treatments.

Hand-Foot Syndrome Presentation Post-Capecitabine Treatment in a Black Patient

Palmar-plantar erythrodysesthesia, commonly known as hand-foot syndrome (HFS), is a side-effect of cancer chemotherapeutic agents such as capecitabine. Patients with HFS oftentimes present with palmoplantar numbness, tingling, burning pain, and/or hyperpigmentation; in advanced grades, blistering and ulceration may occur. In this article, we present the case of a Black patient with grade 1 HFS post-capecitabine treatment for metastasized breast cancer. Prompt recognition for atypical HFS symptom presentation in people of color and discontinuation of capecitabine with supportive treatment can prevent progression to grade 2+ HFS that limits activities of daily living (ADLs).

Study protocol of a single-arm phase 2 study evaluating the preventive effect of topical hydrocortisone for capecitabine-induced hand-foot syndrome in colorectal cancer patients receiving adjuvant chemotherapy with capecitabine plus oxaliplatin (T-CRACC study)

BACKGROUNDS

Clinical evidence of the preventive effectiveness of medium-class topical corticosteroids for capecitabine-induced hand foot syndrome (HFS) is limited. Although the pathogenesis and mechanism of HFS are unclear, inflammatory reactions are thought to be involved in HFS development. This study aimed to evaluate the preventive effect of medium-class topical corticosteroids (hydrocortisone butyrate 0.1% topical therapy) for capecitabine-induced HFS in patients with colorectal cancer receiving adjuvant chemotherapy with capecitabine plus oxaliplatin.

METHODS

This is a single-center, single-arm, phase 2 study. Patients with colorectal cancer scheduled to receive adjuvant chemotherapy with capecitabine plus oxaliplatin are enrolled, and topical hydrocortisone butyrate 0.1% is applied prophylactically in addition to standard moisturizing therapy. The primary endpoint is the incidence of grade ≥ 2 HFS within three months. The secondary endpoints are the time to onset of HFS, rates of dose reduction, schedule delay, discontinuation caused by capecitabine-induced HFS, and other adverse events. All adverse events are evaluated by clinical pharmacists and attending physicians.

DISCUSSION

This study is expected to contribute to the establishment of new supportive care for preventing HFS, not only for colorectal cancer patients receiving adjuvant chemotherapy, but also for various cancer patients receiving capecitabine-based chemotherapy.

A Systematic Review of the Benefit of B-Vitamins as a Complementary Treatment in Cancer Patients

B-vitamins act as enzymatic co-factors in immune functions, therefore they are considered to reduce chemotherapy-induced side effects in cancer patients. We conducted a systematic search, screening five electronic databases (Embase, Cochrane, PsychInfo, CINAHL and Medline) to find studies on the effectiveness and potential harm of B-vitamin therapy on cancer patients. Out of the 7465 search results, 11 RCTs about vitamin B6, B12 and B-vitamins in combination were included in this systematic review. A total of 1546 patients with diverse types of cancer were evaluated. Overall, most studies were of acceptable quality and reported consistent results. Studies examining the effectiveness of vitamin B6 reported that there is no significant impact on decreasing the incidence and severity of chemotherapy-induced side effects (e.g., hand-foot syndrome), the necessity of chemotherapy dose-modifications or improving patients' quality of life, tumor response/progression, and overall survival. Two studies reported that vitamin B12 could be effective in the alleviation of symptoms resulting from chemotherapy; it might decrease motor, sensory and pain symptoms of peripheral neuropathy. However, a combination of B vitamins may not reduce the incidence of chemotherapy-induced peripheral neuropathy. All in all, the evidence on B-vitamins in cancer patients is low and supplementation cannot be recommended.

Oral hyperpigmentation as an initial clinical aspect of hand foot syndrome

Hand-foot syndrome (HFS) is a common adverse effect of anticancer therapy. It is known to cause dermatological symptoms including acral erythema and dysesthesia of the palms and soles of the feet, swelling, pain, itching, and scaling. Some drugs, like capecitabine, are known to trigger this condition. However, pigmentation of the oral mucosa is a rare adverse effect. This study aims to report a case of oral mucosa hyperpigmentation caused by capecitabine therapy before the clinical diagnosis of HFS. A 58-year-old female, diagnosed with invasive breast duct carcinoma, had the central nervous system, liver, skin, and lung metastasis, using capecitabine every day for 14 cycles. Oral examination revealed multifocal black macules on the hard palate, bilateral buccal mucosa, gingival mucosa, and dorsum of the tongue. The clinical hypothesis was oral mucosa hyperpigmentation by capecitabine use and only periodic follow-up was necessary. Hyperpigmentation of oral mucosa by capecitabine is a rare consequence of neoplastic therapy and your association with HFS is unclear, and poorly reported. The report of these events is important to alert oncology health teams about the individual tolerance to capecitabine therapy.

Prophylactic strategies for hand-foot syndrome/skin reaction associated with systemic cancer treatment: a meta-analysis of randomized controlled trials

PURPOSE

Hand-foot syndrome (HFS) and hand-foot skin reaction (HFSR) are common toxicities of several systemic cancer treatments. Multikinase inhibitor-induced HFSR is distinguished from chemotherapy-induced HFS in terms of pathogenesis, symptomatology, and treatment. Multiple trials have investigated the efficacy of preventive strategies such as COX-inhibitors, pyridoxine, and urea cream; however, no consensus has been made. This meta-analysis evaluated data from high-quality trials to provide strong evidence in forming recommendations to prevent systemic cancer therapy-induced HFS/HFSR.

METHODS

A systematic search of PubMed, Embase, Cochrane, clinical trials databases, and hand searching were utilized to identify randomized trials (RCTs) investigating prophylactic strategies for HFS/HFSR in cancer patients receiving systemic treatment. Trials published until August 2021 were included. Using the random effects model, pooled odds ratios were calculated for rates of all-grade and severe HFS/HFSR. Subgroup analysis based on type of cancer treatment given was done.

RESULTS

Sixteen RCTs were included (N=2814). For all-grade HFS/HFSR, celecoxib (OR 0.52, 95% CI 0.32-0.85, p=0.009) and urea cream (OR 0.48, 95% CI 0.39-0.60, p<0.00001) both showed statistically significant risk reduction. Celecoxib was effective in preventing HFS in patients who received capecitabine (50.5% vs 65%, p=0.05), while urea cream was effective in both capecitabine HFS (22.3% vs 39.5%, p=0.02) and sorafenib-induced HFSR (54.9% vs 71.4%, p<0.00001). Pyridoxine at higher doses showed a trend towards benefit in preventing all grade HFS (69.6% vs 74.1%, p=0.23).

CONCLUSIONS

Urea cream and celecoxib are both effective in preventing HFS/HFSR in patients receiving systemic cancer treatment. Particularly, celecoxib is more effective in preventing all-grade capecitabine-induced HFS, while urea cream shows more benefit in preventing moderate to severe sorafenib-induced HFSR. Studies investigating optimal dosing for celecoxib and urea cream are recommended. There is inadequate evidence to make recommendations regarding pyridoxine.

Topical henna and curcumin (Alpha®) ointment efficacy for prevention of capecitabine induced hand-foot syndrome: A randomized, triple-blinded, placebo-controlled clinical

PURPOSE

In this clinical trial, we evaluated Alpha® ointment efficacy in prevention of capecitabine induced hand-foot syndrome (HFS) in patients with gastrointestinal or breast cancers, for the first time.

METHODS

During this pilot, randomized, triple-blinded, placebo-controlled clinical trial, the effect of Alpha® ointment (Lawsonia inermis 3 g and Curcuma longa 0.15 g/ 30 g) was assessed. It was applied on the palms and the soles, two times daily starting at the first day of chemotherapy for 4 consecutive courses. The severity of HFS was assessed at the end of the chemotherapy courses based on World Health Organization (WHO) scale and scored between 0-4.

RESULTS

Ninety eligible patients were included randomly in the treatment or placebo group. Median WHO HFS grade was not significantly different between the two groups, during the follow-up period (P > 0.05). In the weekly assessment, the scores increased meaningfully in both the placebo and treatment groups, but there was a delay in HFS occurrence and deterioration in Alpha ointment group based on post hoc analysis.

CONCLUSION

Administration of Alpha® ointment containing henna and curcumin could not significantly prevent capecitabine induced HFS during 4 courses of treatment, but can somewhat delay its occurrence in patients with gastrointestinal or breast cancer.

Topical heparin as an effective and safe treatment for patients with capecitabine-induced hand-foot syndrome: results of a phase IIA trial supported by proteomic profiling of skin biopsies

Background:

Hand-foot syndrome (HFS) is a common adverse reaction associated with capecitabine chemotherapy that significantly affects the quality of life of patients. This study evaluates the safety and effectiveness of a topical heparin (TH) treatment on the clinical manifestations and anatomopathological alterations of capecitabine-induced HFS. In addition, we performed proteome profiling of skin biopsies obtained from patients with HFS at baseline and after heparin treatment.

Methods:

Patients with grade ⩽ 2 HFS associated with capecitabine were included in this study. The primary end point was the effectiveness of TH in reducing HFS of any grade. Clinical improvement was evaluated by clinicians, and an improvement was perceived by patients who performed a weekly visual analog scale questionnaire. Secondary end points included a comparative histological analysis and protein expression in skin biopsies at baseline and after 3 weeks of HT treatment. Proteomic profiling was carried out using quantitative isobaric labelling and subsequently validated by a T-array.

Results:

Twenty-one patients were included in the study. The median TH treatment time was 7.6 weeks (range = 3.6–41.6 weeks), and the median response time was 3.01 weeks (95% CI = 2.15–3.97). At the end of treatment, 19 of 21 patients (90.48%) responded to treatment with a decrease in one or more grades of HFS. None of the patients experienced adverse effects related to TH usage, nor did they suspend chemotherapy treatment. The main findings observed in skin biopsies after treatment were a decrease in hyperkeratosis and lymphocytic infiltrates. The proteomic analysis showed altered expression of 34 proteins that were mainly related to wound healing, cell growth, and the immune response.

Conclusion:

Based on our results, topical heparin is an effective and safe treatment for clinical manifestations of HFS, probably due to the restauration of skin homeostasis after heparin treatment, as supported by our proteomics-derived data.

Impact of UGT1A1 Polymorphisms on Febrile Neutropenia in Pancreatic Cancer Patients Receiving FOLFIRINOX: A Single-Center Cohort Study

FOLFIRINOX (oxaliplatin, leucovorin, irinotecan, and 5-fluorouracil) is a first-line chemotherapy for metastatic pancreatic cancer (PC). Chemotherapy-induced neutropenia is one of the most serious adverse events associated with advanced PC. Although UGT1A1 polymorphisms are associated with the metabolism of irinotecan, their role as surrogate markers for FOLFIRINOX-induced neutropenia has not been confirmed. We investigated risk factors for FN-in particular, UGT1A1 polymorphisms-in PC patients receiving FOLFIRINOX, using a single-center cohort registry. To investigate the association between UGT1A1 polymorphisms and FN, we divided patients into three groups based on the predicted UGT1A1 phenotype: extensive metabolizer (EM) vs. intermediate metabolizer (IM) vs. poor metabolizer (PM). A total of 154 patients (FN group (n = 31) vs. non-FN group (n = 123)) receiving first-line FOLFIRINOX were identified between December 2017 and July 2020. The Cox regression analysis showed that female sex (HR: 2.20; p = 0.031), Eastern Cooperative Oncology Group performance status = 1 (HR: 2.83; p = 0.008), UGT1A1 IM (HR: 4.30; p = 0.004), and UGT1A1 PM (HR: 4.03; p = 0.028) were statistically significant risk factors for FN. We propose that UGT1A1 is the strongest predictive factor for FN and that this gene should be screened prior to the administration of chemotherapy.

A clinical scoring tool validated with machine learning for predicting severe hand-foot syndrome from sorafenib in hepatocellular carcinoma

Purpose

Sorafenib is an effective therapy for advanced hepatocellular carcinoma (HCC). Hand–foot syndrome (HFS) is a serious adverse effect associated with sorafenib therapy. This study aimed to develop an updated clinical prediction tool that allows personalized prediction of HFS following sorafenib initiation.

Methods

Individual participant data from Phase III clinical trial NCT00699374 were used in Cox proportional hazard analysis of the association between pre-treatment clinicopathological data and grade ≥ 3 HFS occurring within the first 365 days of sorafenib treatment for advanced HCC. Multivariable prediction models were developed using stepwise forward inclusion and backward deletion and internally validated using a random forest machine learning approach.

Results

Of 542 patients, 116 (21%) experienced grades ≥ 3 HFS. The prediction tool was optimally defined by sex (male vs female), haemoglobin (< 130 vs ≥ 130 g/L) and bilirubin (< 10 vs 10–20 vs ≥ 20 µmol/L). The prediction tool was able to discriminate subgroups with significantly different risks of grade ≥ 3 HFS (P ≤ 0.001). The high (score = 3 +)-, intermediate (score = 2)- and low (score = 0–1)-risk subgroups had 40%, 27% and 14% probability of developing grade ≥ 3 HFS within the first 365 days of sorafenib treatment, respectively.

Conclusion

A clinical prediction tool defined by female sex, high haemoglobin and low bilirubin had high discrimination for predicting HFS risk. The tool may enable improved evaluation of personalized risks of HFS for patients with advanced HCC initiating sorafenib.

Biweekly Raltitrexed Combined With Irinotecan as Second-Line Therapy for Patients With Metastatic Colorectal Cancer: A Phase II Trial

Objective

Irinotecan-based doublet chemotherapy strategy was standard second-line backbone for patients with oxaliplatin-refractory metastatic colorectal cancer. The aim of this study was to evaluate tolerability and efficacy of raltitrexed combined with irinotecan biweekly administered as the second-line therapy for mCRC patients.

Methods

The study was a prospective, single-center, non-randomized, open-label phase II clinical trial. Patients with mCRC after failure with oxaliplatin and fluoropyrimidine or its derivatives were enrolled. Irinotecan (180 mg/m²) and raltitrexed (2.5 mg/m²) were given intravenously on day 1. Cycles were repeated every 2 weeks. The primary endpoint was progression-free survival (PFS), and the secondary endpoints included overall response rate (ORR), disease control rate (DCR), overall survival (OS), and adverse events (AEs).

Results

Between December 2012 and October 2016, 33 and 35 patients enrolled were assessed for response and safety, respectively. The ORR was 8.6%, and the DCR was 71.4%. The median PFS was 4.5 months (95% CI 3.8-5.2). The median OS was 12.0 months (95% CI 8.5-15.5). Four patients received conversion therapy to no evidence of disease (NED), and 2 patients were still alive with beyond 24 months survival. The most common grade 3/4 AEs were anorexia (14.3%), vomiting (14.3%), nausea (11.4%), fatigue (8.6%), and leukopenia (8.6%). No one died from treatment-related events. The incidence and severity of toxicity were irrelevant to UGT1A1 status.

Conclusions

The combination of irinotecan with raltitrexed is an efficient, convenient, and acceptable toxic regimen for second-line treatment for mCRC patients.

Milk and Egg Are Risk Factors for Adverse Effects of Capecitabine-Based Chemotherapy in Chinese Colorectal Cancer Patients

Background:

Chemotherapy-induced adverse effects (CIAEs) remain a challenging problem due to their high incidences and negative impacts on treatment in Chinese colorectal cancer (CRC) patients. We aimed to identify risk factors and predictive markers for CIAEs using food/nutrition data in CRC patients receiving post-operative capecitabine-based chemotherapy.

Methods:

Food/nutrition data from 130 Chinese CRC patients were analyzed. Univariate and multivariate analyses were used to identify CIAE-related food/nutrition factors. Prediction models were constructed based on the combination of these factors. The area under the receiver operating characteristic curve (AUROC) was used to evaluate the discrimination ability of models.

Results:

A total of 20 food/nutrition factors associated with CIAEs were identified in the univariate analysis after adjustments for total energy and potential confounding factors. Based on multivariate analysis, we found that, among these factors, dessert, eggs, poultry, and milk were associated with several CIAEs. Most importantly, poultry was an overall protective factor; milk and egg were risk factors for hand-foot syndrome (HFS) and bone marrow suppression (BMS), respectively. Developed multivariate models in predicting grade 1 to 3 CIAEs and grade 2/3 CIAEs both had good discrimination (AUROC values from 0.671 to 0.778, 0.750 to 0.946 respectively), which had potential clinical application value in the early prediction of CIAEs, especially for more severe CIAEs.

Conclusions:

Our findings suggest that patients with high milk and egg intakes should be clinically instructed to control their corresponding dietary intake to reduce the likelihood of developing HFS and BMS during capecitabine-based chemotherapy, respectively.

Spermine-Related DNA Hypermethylation and Elevated Expression of Genes for Collagen Formation are Susceptible Factors for Chemotherapy-Induced Hand-Foot Syndrome in Chinese Colorectal Cancer Patients

Hand-foot syndrome (HFS) is a common capecitabine-based chemotherapy-related adverse event (CRAE) in patients with colorectal cancer (CRC). It is of great significance to comprehensively identify susceptible factors for HFS, and further to elucidate the biomolecular mechanism of HFS susceptibility. We performed an untargeted multi-omics analysis integrating DNA methylation, transcriptome, and metabolome data of 63 Chinese CRC patients who had complete CRAE records during capecitabine-based chemotherapy. We found that the metabolome changes for each of matched plasma, urine, and normal colorectal tissue (CRT) in relation to HFS were characterized by chronic tissue damage, which was indicated by reduced nucleotide salvage, elevated spermine level, and increased production of endogenous cytotoxic metabolites. HFS-related transcriptome changes of CRT showed an overall suppressed inflammation profile but increased M2 macrophage polarization. HFS-related DNA methylation of CRT presented gene-specific hypermethylation on genes mainly for collagen formation. The hypermethylation was accumulated in the opensea and shore regions, which elicited a positive effect on gene expression. Additionally, we developed and validated models combining relevant biomarkers showing reasonably good discrimination performance with the area under the receiver operating characteristic curve values from 0.833 to 0.955. Our results demonstrated that the multi-omics variations associated with a profibrotic phenotype were closely related to HFS susceptibility. HFS-related biomolecular variations in CRT contributed more to the relevant biomolecular mechanism of HFS than in plasma and urine. Spermine-related DNA hypermethylation and elevated expression of genes for collagen formation were closely associated with HFS susceptibility. These findings provided new insights into the susceptible factors for chemotherapy-induced HFS, which can promote the implementation of individualized treatment against HFS.

Moist Exposed Burn Ointment Effectiveness for Capecitabine Associated Grade II and III Hand Foot Syndrome on Stage III Colonic

Background:Hand-foot syndrome (HFS), also known as palmoplantar erythrodysesthesia, is a common adverse effect of the fluoropyrimidine chemotherapy agent capecitabine. Hand-foot syndrome of any grade is reported to affect 43% to 71% of patients treated with single-agent capecitabine chemotherapy. Although not life-threatening, it can have adverse effects on the quality of life (QoL) and daily living activities of a patient.  Sometimes the dose interruptions and reductions required after observation of HFS can also impact on dose intensity and treatment outcomes.  As an option for the treatment of this case, we would reported our preliminary study of the effectiveness of moist exposed burn ointment (MEBO) for stage II and III HFS.   Methods:  We will evaluate the clinical sign and symptoms of hand foot syndrome grade II and III associated with capecitabine as adjuvant chemotherapy agent on advanced stage colorectal cancer.  All patients with HFS will treated with topical MEBO twice daily, the clinical improvement of the symptoms will be recorded.   Results: We reported 8 cases of grade II and III hand foot syndrome, 2 patients were grade III HFS and the others were grade II.  These symptoms occurred after 2 until 3 months after capecitabine administration for locally advanced (stage III) colonic adenocarsinoma.  Topical MEBO were used twice a day for 3 months, pain reduction was achieved with no capicetabine dose interruption and reduction during chemotherapy period.  Allergic reaction was not found during and after MEBO application in this case.   Conclusion:Moist exposed burn ointment was an effective treatment option in managing hand foot syndrome, better option in reducing the pain without interrupting the capecitabine doses.

The frequency of medical reversals in a cross-sectional analysis of high-impact oncology journals, 2009-2018

Background

Identifying ineffective practices that have been used in oncology is important in reducing wasted resources and harm. We sought to examine the prevalence of practices that are being used but have been shown in RCTs to be ineffective (medical reversals) in published oncology studies.

Methods

We cross-sectionally analyzed studies published in three high-impact oncology medical journals (2009–2018). We abstracted data relating to the frequency and characterization of medical reversals.

Results

Of the 64 oncology reversals, medications (44%) represented the most common intervention type (39% were targeted). Fourteen (22%) were funded by pharmaceutical/industry only and 56% were funded by an organization other than pharmaceutical/industry. The median number of years that the practice had been in use prior to the reversal study was 9 years (range 1–50 years).

Conclusion

Here we show that oncology reversals most often involve the administration of medications, have been practiced for years, and are often identified through studies funded by non-industry organizations.

Genomic methylation variations predict the susceptibility of six chemotherapy related adverse effects and cancer development for Chinese colorectal cancer patients

Colorectal cancer (CRC) remains a major concern with high morbidity and mortality worldwide. Despite the positive influence of chemotherapy on the decline in CRC mortality, the negative influence of chemotherapy-related adverse effects (CRAEs) caused by capecitabine (Cap) remains a challenging problem. DNA methylation alteration plays a pivotal role in gene expression regulation. Here, we aimed to screen reliable and novel biomarkers for CRC diagnosis and CRAE prediction using the advanced Illumina Infinium MethylationEPIC (850 K) BeadChip. Paired tumor and normal tissues from 21 Chinese CRC patients who received Cap-based adjuvant chemotherapy were analyzed. CRC-related methylation was characterized by hypermethylated promoter islands and hypomethylated intragenic openseas; CRAE-related methylation was characterized by hyper- (or hypo-) methylated intragenic (or intergenic) regions. Based on three types of methylation profiles (differentially methylated probes, differentially methylated regions, and gene-function-differentially methylated regions), pathway enrichment analyses revealed that CRC-related genes were significantly enriched in the neuronal system, metabolism of RNA, and extracellular matrix organization; CRAE-related genes were abundantly enriched in pathways controlling regeneration functions and immune response. Finally, based on genes within the mostly related pathways and LASSO logistic regression selection, the integrated-methylation-marker systems developed here demonstrated high discriminative accuracy in both CRC diagnosis (AUROC = 1) and CRAE prediction (AUROC = 0.817-1). In conclusion, we conducted a comprehensive DNA methylation analysis of CRC patients with chemotherapy, which provided new insights into the formation of CRC and CRAEs. Most importantly, our findings identified potentially CRAE-related metabolic pathways and markers, providing a valuable reference for personalized medicine promising better safety.

Risk prediction models based on hematological/body parameters for chemotherapy-induced adverse effects in Chinese colorectal cancer patients

PURPOSE

To determine risk factors and develop novel prediction models for chemotherapy-induced adverse effects (CIAEs) in Chinese colorectal cancer (CRC) patients receiving capecitabine.

METHODS

A total of 233 Chinese CRC patients receiving post-operative chemotherapy with capecitabine were randomly divided into a training set (70%) and a validation set (30%). CIAE-related hematological/body parameters were screened by univariate logistic regression. Based on a set of factors selected from LASSO (least absolute shrinkage and selection operator) logistic regression, stepwise multivariate logistic regression was applied to develop prediction models. Area under the receiver operating characteristic (ROC) curve and Hosmer-Lemeshow (HL) test were used to evaluate the discriminatory ability and the goodness of fit of each model.

RESULTS

In total, 35 variables were identified to be associated with CIAEs in univariate analysis. Developed multivariable models had AUCs (area under curve) ranging from 0.625 to 0.888 and 0.428 to 0.760 in the training and validation set, respectively. The grade ≥ 1 anemia multivariable model achieved the best discriminatory ability with AUC of 0.760 (95%CI: 0.609-0.912) and good calibration with HL P value of 0.450. Then, a nomogram was constructed to predict grade ≥ 1 anemia, which included variables of age, pre-operative hemoglobin count, and pre-operative albumin count, with C-indexes of 0.775 and 0.806 in the training and validation set, respectively.

CONCLUSIONS

This study identified valuable hematological/body parameters related to CIAEs. A nomogram based on the multivariable model including three hematological/body predictors can accurately predict grade ≥ 1 anemia, facilitating clinicians to implement personalized medicine early for Chinese CRC patients receiving post-operative chemotherapy for better safety treatment.

How to conduct integrated pharmaceutical care for patients with hand-foot syndrome associated with chemotherapeutic agents and targeted drugs

OBJECTIVE

The objective of this article was to offer practical operational process for pharmacists to successfully conduct integrated pharmaceutical care for patients with hand-foot syndrome associated with chemotherapeutic agents and targeted drugs which may facilitate the work of first-line clinical pharmacist.Data sources: A literature review was conducted in March 2020 of Pubmed, Medline, and EMBASE (2010-2020) using terms such as: hand-foot syndrome, hand-foot skin reaction, palmar-plantar erythrodysesthesia, chemotherapeutic agent, and multikinase inhibitor. Appropriate references from selected articles were also used.Data summary: This paper involves 81 articles including review articles, meta-analysis, and clinical trials which focused on every aspect of hand-foot syndrome, such as manifestation, mechanism, occurrence rate, onset time, patient education, self-monitor scale, and management. Studies were thematically divided into four parts (clinical presentation of HFS, risk stratification, initiation of pharmaceutic care, and management of the adverse reaction).

CONCLUSION

HFS is one of the common adverse events which was associated with many chemotherapeutic agents and multikinase inhibitor drugs. Although the mechanisms and histopathology may be different, they due share some common clinical manifestations. As part of integrated pharmaceutical care for cancer patients, it is important to conduct patient education about the risk of hand-foot syndrome and basic knowledge about hand-foot syndrome management before initiating anticancer therapy. Once hand-foot syndrome happens, evidence-based management could try. If the hand-foot syndrome is intolerable, dose reduction or discontinuation of the anticancer therapy should be considered.

A randomised controlled feasibility trial to evaluate Lawsonia inermis (henna)'s effect on palmar-plantar erythrodysesthesia induced by capecitabine or pegylated liposomal doxorubicin

PURPOSE

To test the effectiveness of henna in the management of palmar-plantar erythrodysesthesia (PPE) in patients receiving treatment with capecitabine or pegylated liposomal doxorubicin (PLD).

METHOD

This was a randomized controlled feasibility study in three specialized tertiary cancer centers with 56 patients with a PPE grade 1 or above and various cancer diagnoses. The intervention included the local application of henna to the affected areas. The control group followed the same process with a henna inert. Primary outcome was PPE grade and secondary outcomes were the EORTC QLQ-C30, PPE-related QoL (HFS-14), activities of daily living (ECOG) and pain. Patients in both groups were assessed at baseline and then weekly at four follow-ups.

RESULTS

PPE grade in the intervention group (1-3.8%) was lower compared to the control group (4-13.38%) and also lower levels of pain were reported by the patients in the intervention group (2.46 ± 1.17) compared to the control (5.57 ± 2.01). ECOG status in the intervention group was improved compared to the control (p = 0.039). The intervention group, experienced higher Global Health Status (p ≤ 0.008), Physical function (p ≤ 0.001), Emotional Function (p = 0.029), Social function (p ≤ 0.001) and lower Fatigue (p ≤ 0.001) and Pain (p ≤ 0.001) compared to the Control group. A statistically significant interaction was found between Group and Time over the weekly measurements of HFS-14 scores (F = 5,009, p ≤ 0.002) indicating the significant effect of the intervention throughout the weekly assessments.

CONCLUSION

The trial provided preliminary evidence on henna's effectiveness for treating PPE during treatment with capecitabine or PLD, with lower PPE grades, better performance status and better HRQoL observed in the henna group. CLINICALTRIALS.

Adverse reactions and adherence to capecitabine: A prospective study in patients with gastrointestinal cancer

INTRODUCTION

Capecitabine is an oral anticancer drug which can cause some adverse reactions and the great challenge for its use is to ensure the medication adherence. The aim of this study was to analyze adverse reactions and adherence to capecitabine in patients with gastrointestinal cancer.

METHODS

A prospective study was performed in a tertiary teaching hospital in Brazil. Outpatients undergoing capecitabine treatment for colorectal or gastric cancer were followed for three cycles of treatment. Patient demographic and clinical characteristics data were collected. Adverse reactions were analyzed using Common Terminology Criteria for Adverse Events (CTCAE) v.4. Adherence to capecitabine were evaluated using Morisky-Green and MedTake tests. Statistical analysis was conducted using Chi-square, Fisher's exact and McNemer tests.

RESULTS

One hundred and four patients were enrolled in this study, with a mean age was 58.5 ± 10.9 years; 51.0% were men and 51.0% Caucasian. Nausea and diarrhea were the most frequently reported adverse reactions (82.7% and 62.5%, respectively), followed by vomiting (54.8%), fatigue (54.8%), and hand-foot syndrome (53.9%). Nausea and diarrhea were also the most severe adverse reactions. Most patients were adherent to capecitabine in all cycles of treatment using the Morisky-Green test. Adherence increased significantly between cycle 1 and cycle 2 by MedTake test (p < 0.001). Some demographic and clinical characteristics were associated with adverse reactions (e.g., age and nausea, gender and nausea and vomiting) and capecitabine adherence (e.g., marital status and educational level) as well as some adverse reactions were associated with capecitabine adherence (hand-foot syndrome and nausea).

CONCLUSIONS

Clinical oncology pharmacists must provide patient information on the correct use of capecitabine, manage adverse reactions, and monitor adherence to treatment. Strategies to prevent non-adherence to capecitabine must be adopted to ensure the success of pharmacotherapy.

Polymorphisms in TYMS for Prediction of Capecitabine-Induced Hand-Foot Syndrome in Chinese Patients with Colorectal Cancer

Purpose

Capecitabine is an extensively used oral prodrug of 5-fluorouracil in treatment of colon cancer and is known to cause hand-foot syndrome (HFS). As the target enzyme for capecitabine, thymidylate synthase (TYMS) plays a key role for 5-fluorouracil metabolism and has been associated with some side effects caused by capecitabine. The aim of our study is to identify the possible genetic predictors of capecitabine-induced HFS (CAP-HFS) in Chinese colorectal cancer patients.

Materials and Methods

Whole exons of TYMS were sequenced for 288 extreme phenotype HFS patients, including 144 severe or early-onset (first 2 cycles) moderate HFS extreme cases and 144 extreme controls with no reported HFS. The associations between polymorphisms and CAP-HFS were analyzed using logistic regression under an additive model.

Results

We identified a novel risk mutation (c.1A>G, chr18:657743), was associated with severe HFS in an extreme case who was affected during the first cycle of treatment. Moreover, we identified three new variants, rs3786362, rs699517, rs2790, and two previously reported variants, 5’VNTR 2R/3R and 3′-untranslated region 6-bp ins-del, which were significantly associated with CAP-HFS (p < 0.05). In silico analysis revealed that the effect of these polymorphisms in the TYMS region on the development of HFS might not be restricted solely to the regulation of TYMS expression, but also the TYMS catalytic activity through the indirect effect on ENOSF1 expression.

Conclusion

This study identified new polymorphisms in TYMS gene significantly associated with CAP-HFS, which may serve as useful genetic predictors for CAP-HFS and help to elucidate the underlying mechanism of HFS.

Pyridoxine for prevention of hand-foot syndrome caused by chemotherapy agents: a meta-analysis

BACKGROUND

Hand-foot syndrome (HFS) is a common systemic skin toxicity syndrome caused by chemotherapy agents. However, there is no uniform clinical treatment for HFS. It is reported that pyridoxine (vitamin B6) can be used to prevent HFS, but the evidence is insufficient.

AIM

To determine whether pyridoxine can be used to prevent HFS caused by chemotherapy agents.

METHODS

Literature database searches were performed on PubMed, Web of Science, Embase, Cochrane Library and China National Knowledge Infrastructure. The efficacy of pyridoxine was evaluated by the incidence of HFS (any grade) or severe HFS (grade ≥ 2).

RESULTS

Fourteen studies involving 1570 patients were included in this meta-analysis. There were no significant differences between the pyridoxine and control groups in the prevention of HFS (OR = 0.84, 95% CI 0.67-1.05, P = 0.09) or in the incidence of grade ≥ 2 HFS (OR = 0.87, 95% CI 0.70-1.09, P = 0.39, respectively). The subgroup analysis of pyridoxine dose also showed no significant difference between the two groups in preventing HFS grade ≥ 2 (OR = 0.79, 95% CI 0.62-0.99, P = 0.30).

CONCLUSIONS

We did not find adequate evidence to support the idea that the use of pyridoxine can prevent HFS and reduce the incidence of HFS grade ≥ 2. However, the preventive use of pyridoxine might have a tendency to reduce the incidence of HFS.

AZIN1-AS1, A Novel Oncogenic LncRNA, Promotes the Progression of Non-Small Cell Lung Cancer by Regulating MiR-513b-5p and DUSP11

Background

Emerging researches have demonstrated that aberrantly expressed long non-coding RNAs (lncRNAs) have great significance in non-small cell lung cancer (NSCLC) progression. The aim of this study was to explore the role of lncRNA AZIN1 antisense RNA 1 (AZIN1-AS1) in NSCLC and the related mechanism.

Methods

Expressions of AZIN1-AS1 and miR-513b-5p in NSCLC samples were detected by qRT-PCR. NSCLC cell lines (H1299 and HCC827) were used in vitro assays. CCK-8 assay, EdU assay, wound healing test and Transwell assay were carried out to test the biological influence of AZIN1-AS1 on NSCLC cells. Subcutaneous xenotransplanted tumor model and tail vein injection model were established to test the role of AZIN1-AS1 in vivo. Interactions between AZIN1-AS1 and miR-513b-5p, miR-513b-5p and dual-specificity phosphatase 11 (DUSP11) were determined by bioinformatic analysis, qRT-PCR, Western blot, and luciferase reporter assay.

Results

AZIN1-AS1 was up-regulated in NSCLC cells and tissues, while miR-513b-5p was significantly down-regulated. Silencing of AZIN1-AS1 or overexpression of miR-513b-5p markedly inhibited proliferation, migration and invasion of NSCLC cells, while overexpression of AZIN1-AS1 or inhibition of miR-513b-5p functioned oppositely. Importantly, AZIN1-AS1 mediated the promotion of malignancy of NSCLC cells was reversed by miR-513b-5p mimics. What’s more, AZIN1-AS1 could down-regulate miR-513b-5p via sponging it, and there existed a negative correlation between AZIN1-AS1 expression and miR-513b-5p expression in NSCLC samples. AZIN1-AS1 also enhanced the expression levels of DUSP11, which was proved as a target gene of miR-513b-5p. Further in vivo experiments showed that silencing of AZIN1-AS1 decreased tumor growth and metastasis, which was accompanied by overexpression of miR-513b-5p and inhibition of DUSP11 in tumor tissues.

Conclusion

AZIN1-AS1 acts as a tumor promoter in NSCLC, which is ascribed to the regulation of miR-513b-5p and DUSP11.

Henna Application in the Prevention of Capecitabine-Induced Hand-Foot Syndrome in Breast and Colorectal Cancer Patients

AIM

This study investigates the prophylactic effect of henna on the occurrence of hand-foot syndrome (HFS) in patients receiving capecitabine for breast and colorectal cancer.

METHOD

This experimental study was carried out between May 2014 and May 2015. In this self-control experimental study, 52 patients with breast and colorectal cancer were included on the first day of capecitabine treatment and had a minimum follow-up of 3 cycles. One hand/foot of each patient constituted the study hand/foot, whereas the others constituted the control. Henna was administered to the study hand/foot on the first day of treatment and application renewed weekly. Development of grade 1-3 toxicity was set as the termination criterion for study.

RESULTS

Painful skin changes such as rawness, intumescence and bulla formation, blocking the daily activities or self-care were observed in 26.9% of the patients in the 3rd or 4th cycles of treatment. Development time and severity of skin changes over time did not differ significantly between the study and the control hand/foot.

CONCLUSION

Further studies with a larger sample size are needed to conclude on the prophylactic effect of henna in the management of the HFS.

Targeted Therapy- and Chemotherapy-Associated Skin Toxicities: Systematic Review and Meta-Analysis

PROBLEM IDENTIFICATION

Preventing and managing skin toxicities can minimize treatment disruptions and improve well-being. This systematic review aimed to evaluate the effectiveness of interventions for the prevention and management of cancer treatment-related skin toxicities.

LITERATURE SEARCH

The authors systematically searched for comparative studies published before April 1, 2019. Study selection and appraisal were conducted by pairs of independent reviewers.

DATA EVALUATION

The random-effects model was used to conduct meta-analysis when appropriate.

SYNTHESIS

39 studies (6,006 patients) were included; 16 of those provided data for meta-analysis. Prophylactic minocycline reduced the development of all-grade and grade 1 acneform rash in patients who received erlotinib. Prophylaxis with pyridoxine 400 mg in capecitabine-treated patients lowered the risk of grade 2 or 3 hand-foot syndrome. Several treatments for hand-foot skin reaction suggested benefit in heterogeneous studies. Scalp cooling significantly reduced the risk for severe hair loss or total alopecia associated with chemotherapy.

IMPLICATIONS FOR RESEARCH

Certainty in the available evidence was limited for several interventions, suggesting the need for future research.

ONS Guidelines™ for Cancer Treatment-Related Skin Toxicity

BACKGROUND

Management of cancer treatment-related skin toxicities can minimize treatment disruptions and improve patient well-being.

OBJECTIVES

This guideline aims to support patients and clinicians in decisions regarding management of cancer treatment-related skin toxicities.

METHODS

A panel developed a guideline for management of cancer treatment-related skin toxicities using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) for certainty of evidence and the National Academies of Sciences, Engineering, and Medicine criteria for trustworthy guidelines. The Cochrane risk-of-bias tool assessed risk of bias. A quantitative or narrative synthesis of the evidence was completed.

RESULTS

The panel issued seven conditional recommendations for epidermal growth factor receptor inhibitor rash, hand-foot skin reaction, hand-foot syndrome, and chemotherapy-induced alopecia. The panel suggested strategies for prevention and treatment for all toxicities except hand-foot syndrome, which only has a prevention recommendation.

IMPLICATIONS FOR NURSING

Cancer treatment-related skin toxicities can significantly affect quality of life. Incorporation of these interventions into clinical care can improve patient outcomes.

Regulatory CDH4 Genetic Variants Associate With Risk to Develop Capecitabine-Induced Hand-Foot Syndrome

Capecitabine-induced hand-foot syndrome (CiHFS) is a common dermatological adverse reaction affecting around 30% of patients with capecitabine-treated cancer, and the main cause of dose reductions and chemotherapy delays. To identify novel genetic factors associated with CiHFS in patients with cancer, we carried out an extreme-phenotype genomewide association study in 166 patients with breast and colorectal capecitabine-treated cancer with replication in a second cohort of 85 patients. We discovered and replicated a cluster of four highly correlated single-nucleotide polymorphisms associated with susceptibility to CiHFS at 20q13.33 locus (top hit = rs6129058, hazard ratio = 2.40, 95% confidence interval = 1.78-3.20; P = 1.2 × 10^-8 ). Using circular chromosome conformation capture sequencing, we identified a chromatin contact between the locus containing the risk alleles and the promoter of CDH4, located 90 kilobases away. The risk haplotype was associated with decreased levels of CDH4 mRNA and the protein it encodes, R-cadherin (RCAD), which mainly localizes in the granular layer of the epidermis. In human keratinocytes, CDH4 downregulation resulted in reduced expression of involucrin, a protein of the cornified envelope, an essential structure for skin barrier function. Immunohistochemical analyses revealed that skin from patients with severe CiHFS exhibited low levels of RCAD and involucrin before capecitabine treatment. Our results uncover a novel mechanism underlying individual genetic susceptibility to CiHFS with implications for clinically relevant risk prediction.

In Vitro Assessment of Fluoropyrimidine-Metabolizing Enzymes: Dihydropyrimidine Dehydrogenase, Dihydropyrimidinase, and β-Ureidopropionase

Fluoropyrimidine drugs (FPs), including 5-fluorouracil, tegafur, capecitabine, and doxifluridine, are among the most widely used anticancer agents in the treatment of solid tumors. However, severe toxicity occurs in approximately 30% of patients following FP administration, emphasizing the importance of predicting the risk of acute toxicity before treatment. Three metabolic enzymes, dihydropyrimidine dehydrogenase (DPD), dihydropyrimidinase (DHP), and β-ureidopropionase (β-UP), degrade FPs; hence, deficiencies in these enzymes, arising from genetic polymorphisms, are involved in severe FP-related toxicity, although the effect of these polymorphisms on in vivo enzymatic activity has not been clarified. Furthermore, the clinical usefulness of current methods for predicting in vivo activity, such as pyrimidine concentrations in blood or urine, is unknown. In vitro tests have been established as advantageous for predicting the in vivo activity of enzyme variants. This is due to several studies that evaluated FP activities after enzyme metabolism using transient expression systems in Escherichia coli or mammalian cells; however, there are no comparative reports of these results. Thus, in this review, we summarized the results of in vitro analyses involving DPD, DHP, and β-UP in an attempt to encourage further comparative studies using these drug types and to aid in the elucidation of their underlying mechanisms.

Gut Microbiota Profiling in Patients With HER2-Negative Metastatic Breast Cancer Receiving Metronomic Chemotherapy of Capecitabine Compared to Those Under Conventional Dosage

Purpose: Low-dose metronomic chemotherapy can achieve disease control with reduced toxicity compared to conventional chemotherapy in maximum tolerated dose. Characterizing the gut microbiota of cancer patients under different dosage regimens may describe a new role of gut microbiota associated with drug efficacy. Therefore, we evaluated the composition and the function of gut microbiome associated with metronomic capecitabine compared to conventional dosage. Methods: The fecal samples of HER2-negative metastatic breast cancer patients treated with capecitabine as maintenance chemotherapy were collected and analyzed by 16S ribosome RNA gene sequencing. Results: A total of 15 patients treated with metronomic capecitabine were compared to 16 patients under a conventional dose. The unweighted-unifrac index of the metronomic group was statistically significantly lower than that of the routine group (P = 0.025). Besides that, the Bray-Curtis distance-based redundancy analysis illustrated that the microbial genera between the two groups can be separated partly. Nine Kyoto Encyclopedia of Genes and Genomes (KEGG) modules were enriched in the metronomic group, while no KEGG modules were significantly enriched in the routine group. Moreover, univariate and multivariate analyses suggested that the median progression-free survival (PFS) was significantly shorter in patients with the gut microbial composition of Slackia (9.2 vs. 32.7 months, P = 0.004), while the patients with Blautia obeum had a significantly prolonged PFS than those without (32.7 vs. 12.9 months, P = 0.013). Conclusions: The proof-of-principle study suggested that the gut microbiota of patients receiving metronomic chemotherapy was different in terms of diversity, composition, and function from those under conventional chemotherapy, and the presence of specific bacterial species may act as microbial markers associated with drug resistance monitoring and prognostic evaluation.

Preventive effect of celecoxib in sorafenib-related hand-foot syndrome in hepatocellular carcinoma patients, a single-center, open-label, randomized, controlled clinical phase III trial

Skin toxicity, especially hand-foot syndrome (HFS), is one of the most common sorafenib-induced adverse events (AEs) in hepatocellular carcinoma (HCC) patients, leading to treatment interruption and failure. Mucocutaneous inflammation may cause HFS; therefore, we investigated whether celecoxib can alleviate HFS, improve patients' quality of life and increase survival when administered in conjunction with active therapy. Our randomized, open-label study prospectively enrolled 116 advanced HCC patients receiving sorafenib as targeted therapy from July 2015 to July 2016. All patients were randomly assigned (1:1) via a computer-generated sequence to receive sorafenib with or without celecoxib. Sorafenib-related AEs were recorded, Survival was compared between the two groups. Compared to the Sorafenib group, the SoraCele group had lower incidence rates of ≥ grade 2 and grade 3 HFS (63.8% vs 29.3%, P < 0.001; 19.0% vs 3.4%, P = 0.008, respectively), hair loss, rash and abdominal pain. Kaplan-Meier analysis revealed a lower risk of ≥ grade 2 HFS (HR, 0.384; P = 0.002) and a lower dose reduction/interruption rate (46.6% to 15.5%, P < 0.001) in the SoraCele group. Cox proportional hazards regression analysis demonstrated that celecoxib was the only independent predictive factor of developing ≥ grade 2 HFS (HR, 0.414; P = 0.004). Longer progression-free survival (PFS) was also observed in the SoraCele group (P = 0.039), although overall survival was not prolonged (P = 0.305). These results suggest that sorafenib + Celecoxib administration alleviated sorafenib-related skin toxicity. Longer PFS was achieved in clinical practice, although overall survival was not prolonged (ClinicalTrials.gov: NCT02961998).

Scrotal and Penile Erythrodysesthesia Associated with Neoadjuvant Capecitabine Chemoradiation

Capecitabine, a prodrug of fluorouracil, is a component of many chemotherapy regimens used to treat a wide variety of malignancies. One of the most common adverse reactions experienced by those who have been exposed to capecitabine is palmar-plantar erythrodysesthesia (PPE). PPE is a cutaneous manifestation of chemotherapy-related drug toxicity that has signs and symptoms of erythema, edema, pain, ulceration, or desquamation of the palms of the hands and soles of the feet. The signs and symptoms occur with varying severity. There are few reports of the genitalia being similarly affected. The following case describes a patient with locally advanced rectal cancer who experienced erythrodysesthesia secondary to a capecitabine-containing neoadjuvant chemoradiation regimen that primarily and most significantly involved the genitalia. 

Toxicity and Pharmacogenomic Biomarkers in Breast Cancer Chemotherapy

Breast cancer (BC) is one of the most prevalent types of cancer worldwide with high morbidity and mortality rates. Treatment modalities include systemic therapy, in which chemotherapy is a major component in many cases. Several chemotherapeutic agents are used in combinations or as single agents with many adverse events occurring in variable frequencies. These events can be a significant barrier in completing the treatment regimens. Germline genomic variants are thought of as potential determinants in chemotherapy response and the development of side effects. Some pharmacogenomic studies were designed to explore germline variants that can be used as biomarkers for predicting developing toxicity or adverse events during chemotherapy in BC. In this review, we reassess and summarize the major findings of pharmacogenomic studies of chemotherapy toxicity during BC management. In addition, deficiencies hampering utilizing these findings and the potential targets of future research are emphasized. Main insufficiencies in toxicity pharmacogenomics studies originate from study design, sample limitations, heterogeneity of selected genes, variants, and toxicity definitions. With the advent of high throughput genotyping techniques, researchers are expected to explore the identified as well as the potential genetic biomarkers of toxicity and efficacy to improve BC management. However, to achieve this, the limitations of previous work should be evaluated and avoided to reach more conclusive and translatable evidence for personalizing BC chemotherapy.

SNPs in the COX-2/PGES/EP signaling pathway are associated with risk of severe capecitabine-induced hand-foot syndrome

PURPOSE

Capecitabine is a widely used 5-fluorouracil oral prodrug. Hand-foot syndrome (HFS), one of the most common adverse events of capecitabine, impacts patients' quality of life seriously. The pathogenesis of HFS remains unclear but was usually considered as a type of inflammation conducted by cyclooxygenase-2 (COX-2). The COX-2/PGES/EP signaling pathway plays an important role in the inflammatory reaction. We hypothesized that the single nucleotide polymorphisms (SNPs) in this pathway may be associated with the risk of HFS induced by capecitabine.

PATIENTS AND METHODS

Using DNA from blood samples of 225 patients, we genotyped 19 SNPs in 6 core genes (COX-2, PGES, EP1, EP2, EP3, and EP4). Common Terminology Criteria for Adverse Events version 3.0 was used to grade hand-foot syndrome. We used logistic regression analysis to evaluate the correlations between genotype variants and occurrence of HFS. The cumulative incidence of HFS was assessed by Kaplan-Meier analysis.

RESULTS

Among the 225 participants, 58.6% (132/225) patients developed into HFS, including 41.3% (93/225) grade 1 HFS, 10.2% (23/225) grade 2 HFS and 7.1% (16/225) grade 3 HFS. Multivariate logistic regression analysis showed the AG/GG genotype of rs3810255 to be associated with a significantly higher risk of grade 2/3 HFS, while the AG/AA genotype of rs17131450 to be associated with a significantly lower risk of grade 2/3 HFS (OR = 3.646, P = 0.011; and OR = 0.266, P = 0.036; respectively).

CONCLUSION

Our study showed that rs3810255 AG/GG genotypes and rs17131450 GG genotypes to be associated with high risk of capecitabine-induced HFS.

Management of cytotoxic chemotherapy-induced hand-foot syndrome

Improvements in systemic cancer treatments have resulted in more patients surviving for prolonged periods of time on treatment. This has made treatment-related toxicity and quality of life concerns increasingly relevant. Hand-foot syndrome (HFS) is a common skin reaction to systemic therapy that should be anticipated with chemotherapeutic treatments such as pegylated liposomal doxorubicin, docetaxel, and fluoropyrimidines. In this review we discuss current knowledge of the diagnosis, incidence, pathogenesis, and management of hand-foot syndrome (HFS). Although HFS is not life threatening, it can cause significant discomfort and impairment of function, especially in elderly patients, and may seriously impact quality of life. The incidence of HFS is dependent on the chemotherapeutic drug used, the treatment schedule, and the median duration of treatment. Effective measures for prevention and treatment of HFS include systemic and topical treatments, dose reductions, and switching to other drugs in the same class that are associated with lower rates of HFS. These approaches allow patients to continue cancer treatment while reducing negative impacts on quality of life. Awareness and early recognition are important to ensure timely treatment and avoidance of dose reductions or treatment discontinuation. We provide useful recommendations to guide the management of HFS in clinical practice.

Management of dermatologic adverse events from cancer therapies: recommendations of an expert panel

With the development of new cancer therapies, systemic toxicity profile and effects on survival achieved an important improvement. However, a constellation of toxicities has emerged, even more remarkably, cutaneous adverse events. This report, developed by a board of Brazilian experts in oncodermatology, aims to establish a guideline for the dermatological care of oncologic patients. When possible, evidence-based recommendations were made, but in many cases, when strong evidence was not available, a consensus was reached, based on some data supporting therapies combined with personal experiences.

Effect of Chinese Herbal Compound LC09 on Patients With Capecitabine-Associated Hand-Foot Syndrome: A Randomized, Double-Blind, and Parallel-Controlled Trial

Background: LC09 is composed with 5 kinds of traditional Chinese herbal medicines (Astragalus membranaceus, flowers carthami, lithospermum, geranium wilfordii, and radix angelicae) which are used in China and developed over several thousand years. Aim: To assess the effectiveness and safety of herbal compound LC09 on patients with capecitabine-associated hand-foot syndrome (HFS). Materials and Methods: In this randomized, double-blind, and parallel-controlled study, 156 patients that diagnosed with HFS were randomly assigned to a treatment group (n = 78) or control group (n = 78). Patients were evaluated every week by the National Cancer Institute (NCI) grade and Numerical Rating Scale (NRS) pain scores. The Dermatology Life Quality Index (DLQI) scale and Instrumental Activity of Daily Living (IADL) scale were used to assess the quality of life before the treatment, and at 1 week and after the treatment of 2 cycles. Results: At the baseline, no significant differences were observed between the 2 groups. After treatment, significant differences in NCI grade and NRS pain scores were observed between the 2 groups (P < .01). In addition, HFS effectiveness rate and pain alleviation rate were significantly higher in the treatment group compared with the control group (P < .01). Furthermore, the chemotherapy completion rate between 2 groups was significantly different (P = .002). In addition, no adverse reactions were observed in either LC09 or control group. Conclusion: LC09 can decrease NCI grade and significantly alleviate pain in HFS patients. Besides, it can also increase chemotherapy completion rate.
