Incidence and implications of chemotherapy related hand-foot syndrome

Incidence and severity of hand-foot syndrome in cancer patients receiving infusional 5-fluorouracil or oral capecitabine-containing chemotherapy regimens

BackgroundHand-foot syndrome is a common adverse effect of 5-fluorouracil infusion or oral capecitabine. Several types of research have shown that clinical presentations of hand-foot syndrome vary by ethnicity, so we tried to look at the incidence and severity of hand-foot syndrome in individuals receiving infusional 5-fluorouracil or oral capecitabine at a tertiary care hospital in central Kerala, India.AimTo determine the incidence and severity of hand-foot syndrome in cancer patients receiving infusional 5-fluorouracil or oral capecitabine chemotherapy regimen.MethodologyA prospective cohort study was conducted at the oncology department of a tertiary care hospital in Kerala, India. Our study subjects were those who underwent chemotherapy with infusional 5-fluorouracil or oral capecitabine and later developed hand-foot syndrome. The patients who developed hand-foot syndrome after chemotherapy were assessed to determine the incidence of hand-foot syndrome. Also, the severity of hand-foot syndrome among cancer patients was estimated using CTCAE version 5.0.ResultsOut of 104 study participants, 76.90% (N = 80) of the patients had hand-foot syndrome, whereas 23.07% (N = 24) did not. The onset of hand-foot syndrome symptoms varied depending on the patient. Most patients (60%) displayed grade-one symptoms in their third cycle. The remaining patients showed grade-one symptoms in cycle one (3.75%), cycle two (17.5%), and cycle four (18.75%). The study also showed t no association between the incidence of hand-foot syndrome and the type of regimen.ConclusionThe majority of the patients suffered from hand-foot syndrome. As well, most of the patients were afflicted by grade one hand-foot syndrome.

Therapy-related hand-foot syndrome: a review

Anti-tumor drugs cause hand-foot syndrome through a variety of pathogenic mechanisms. Some chemotherapeutic medications that can cause HFS include 5FU, doxorubicin, capecitabine, high dose cytarabine, and others. These medications each have a unique mechanism resulting in HFS. The histopathological characteristics, clinical manifestations, and variations in gender, ethnicity, or genetic makeup might also impact the development of HFS as an adverse drug reaction. Even though the disease might not become life-threatening, it is nevertheless vital to manage it with therapeutic interventions or by withholding the medication in order to enhance the patient's outcome. Current developments in pharmacological and non-pharmacological therapeutic approaches for managing symptoms also emphasis the same.

Pseudoephedrine-induced Fixed Drug Eruption in a Scuba Diver With Recurrent Palmoplantar Exfoliation

This report presents a case of pseudoephedrine-induced non-pigmented bullous fixed drug eruption (NBFDE) manifesting as recurrent palmoplantar exfoliation in a scuba diver. It emphasizes the importance of considering drug allergies in the differential diagnosis when divers present with peeling hands and soles. A 38-year-old female scuba diver experiencing recurrent palmoplantar exfoliation underwent a clinical evaluation, patch testing, an interferon-gamma enzyme-linked immunospot (ELISpot) assay, and graded drug challenges with pseudoephedrine and phenylephrine. Patch testing yielded negative results; however, the ELISpot assay indicated a strong immune response to pseudoephedrine. A graded challenge involving pseudoephedrine successfully reproduced the symptoms, confirming a diagnosis of pseudoephedrine-induced NBFDE. Subsequently, a challenge with phenylephrine elicited a milder reaction, suggesting it as a potential alternative medication for the patient. This case highlights NBFDE as a potential cause of skin peeling in scuba divers who are allergic to pseudoephedrine. It emphasizes the importance of considering drug allergies when diagnosing palmoplantar exfoliation in divers and underscores the need for a thorough evaluation of medication use in this group. Alternative medications and management strategies should be considered for divers with a pseudoephedrine allergy to prevent ear barotrauma while minimizing the risk of adverse skin reactions.

Kupffer cells determine intrahepatic traffic of PEGylated liposomal doxorubicin

Intrahepatic accumulation dominates organ distribution for most nanomedicines. However, obscure intrahepatic fate largely hampers regulation on their in vivo performance. Herein, PEGylated liposomal doxorubicin is exploited to clarify the intrahepatic fate of both liposomes and the payload in male mice. Kupffer cells initiate and dominate intrahepatic capture of liposomal doxorubicin, following to deliver released doxorubicin to hepatocytes with zonated distribution along the lobule porto-central axis. Increasing Kupffer cells capture promotes doxorubicin accumulation in hepatocytes, revealing the Kupffer cells capture-payload release-hepatocytes accumulation scheme. In contrast, free doxorubicin is overlooked by Kupffer cells, instead quickly distributing into hepatocytes by directly crossing fenestrated liver sinusoid endothelium. Compared to free doxorubicin, liposomal doxorubicin exhibits sustained metabolism/excretion due to the extra capture-release process. This work unveils the pivotal role of Kupffer cells in intrahepatic traffic of PEGylated liposomal therapeutics, and quantitively describes the intrahepatic transport/distribution/elimination process, providing crucial information for guiding further development of nanomedicines.

Pegylated liposomal doxorubicin combined with cyclophosphamide and vincristine in pediatric patients with relapsed/refractory solid tumor: a single-arm, open-label, phase I study

Background

The combined vincristine, pegylated liposomal doxorubicin (PLD), and cyclophosphamide (VPC) regimen has never been studied in pediatric patients.

Methods

This open-label, single-center, single-arm phase I study utilizing a "3 + 3" design enrolled children with relapsed/refractory (R/R) solid tumors. Three dose levels of PLD (Duomeisu®) were studied (30, 40, or 50 mg/m2) in combination with cyclophosphamide (1500 mg/m2), mesna (1500 mg/m2), and vincristine (1.5 mg/m2, maximum 2 mg) once every 3 weeks. The primary endpoints included safety, the maximum tolerated dose (MTD) of PLD (Duomeisu®), and the recommended phase 2 dose (RP2D) of PLD (Duomeisu®) for further phase 2 investigation. The secondary endpoints were objective response rate (ORR) and disease control rate (DCR). This study is registered with ClinicalTrials.gov, NCT04213612.

Findings

Between January 7, 2020, and November 18, 2021, 34 patients were eligible and evaluable for toxicity, while 26 patients were evaluable for response. The MTD of PLD (Duomeisu®) was 30 mg/m2. The most common adverse event (AE) was grade 3 or 4 neutropenia (61.8%). The most common grade 1 or 2 non-hematologic AE and cardiotoxicity effects were vomiting (35.3%) and abnormal electrocardiogram T waves (20.6%), respectively. ORR and DCR to VPC regimen after two cycles were 50.0% and 92.3%, respectively. Targeted gene panel sequencing revealed the activation of TP53 mutation may be an adverse prognostic factor.

Interpretation

The VPC regimen showed a promising safety profile and had preliminary efficacy in children with R/R solid tumors. The RP2D for PLD (Duomeisu®) combined with cyclophosphamide and vincristine is 30 mg/m2 once every 3 weeks.

Photobiomodulation in the treatment of palmar-plantar erythrodysesthesia: a randomised controlled clinical study protocol

INTRODUCTION

Hand-foot syndrome, also known as palmar-plantar erythrodysesthesia (PPE), is a complication caused by chemotherapy. Clinically, it manifests as erythema and oedema on the palms of the hands and feet, dry and scaly skin, accompanied by a sensation of tightness and pain. Extreme cases have blisters and ulcerations that may require hospitalisation and/or pause in cancer treatment. It can also be accompanied by paraesthesia. Considering the characteristics, photobiomodulation (PBM) may reduce the PPE effects. The objective of this protocol will be to evaluate the efficacy of PBM in reducing PPE induced by capecitabine and 5-fluorouracil chemotherapy.

METHODS AND ANALYSIS

This will be a randomised controlled, double-blind, double-centre clinical trial (Centro Asistencial del Sindicato Médico del Uruguay and Instituto Nacional del Cáncer from Uruguay). The sample population (40 individuals) will be divided into two groups: group 1 will receive moisturising cream plus PBM treatment and group 2 moisturising cream plus PBM sham treatment, at the ratio of 1:1. PBM will be performed at 630 nm two times per week in palmoplantar areas of the hands and feet (4 J/cm2), for 4 weeks. The PPE degree and the data referring to the chemotherapy treatment plan will be measured, prior to the start of treatment in the middle and at the end of it. Quality of life questionnaires will be applied at the beginning of the trial and at the end of treatment. The data will be analysed based on the intention-to-treat analysis and α<0.05 will be considered statistically significant.

ETHICS AND DISSEMINATION

The protocol was approved by the Research Ethics Committee of Universidad Católica del Uruguay (220316b), of Centro Asistencial del Sindicato Médico del Uruguay (221989) and of Instituto Nacional del Cáncer (2023-04). The recruitment has already started (March 2023).

Management of cutaneous adverse events caused by antineoplastic therapies: a single-center experience

INTRODUCTION

Cutaneous adverse events can occur in patients treated with antineoplastic treatments, albeit their incidence has not been defined yet. The clinical presentation of CAEs related to anticancer treatments can vary. The purpose of our study is to characterize skin toxicities during oncological treatments, manage such adverse events to improve patients' quality of life, and ensure therapeutic adherence.

METHODS

We conducted a single-center prospective study which provided the enrollment of all patients referred to the Skin Toxicity Outpatient Clinic for the occurrence of cutaneous adverse events secondary to an ongoing antineoplastic treatment, between July 2021 and June 2023. We analyzed clinical features, and we described our therapeutic approach.

RESULTS

Based on the type of drug assumed, chemotherapy-induced skin toxicity in 24 (38.7%) of the 62 evaluated patients, target therapies in 18 (29.0%), CDK4/6 cyclin inhibitors in 12 (19.4%), and immunotherapy in 6 (9.7%), while skin adverse events secondary to hormone therapy were seen in two patients. The most common cutaneous adverse event in our experience was rosaceiform rash of the face, followed by eczematous rash, hand-foot syndrome, and folliculitis.

CONCLUSION

The present study is aimed at describing the variability and heterogeneity of clinical manifestations of different pharmacological classes used in oncological patients, as well as the different pathogenesis of skin damage. Chemotherapy very frequently causes skin toxicities that are often underestimated by clinicians. Their adequate recognition and optimal treatment lead to total recovery and allow better adhesion to chemotherapy.

Replacing cholesterol with asiatic acid to prolong circulation and enhance anti-metastatic effects of non-PEGylated liposomes

Cholesterol is an indispensable component of most liposomes, heavily influencing their physical and surface properties. In this study, cholesterol in non-PEGylated liposomes was replaced by its analog, asiatic acid (AA), to generate liposomes with an alternative composition. These AA liposomes are generally smaller and more rigid than conventional liposomes, circulate longer in the body, and accumulate more in primary tumors and lung metastases in vivo. On the other hand, as an active ingredient, AA can decrease TGF-β secretion to inhibit the epithelial-mesenchymal transition (EMT) process, increase the sensitivity of tumor cells to doxorubicin (DOX), and synergize with DOX to enhance the immune response, thus improving their antitumor and anti-metastasis efficiency. Based on this rationale, DOX-loaded AA liposomes were fabricated and tested against triple-negative breast cancer (TNBC). Results showed that compared with conventional liposomes, the DOX-AALip provided approximately 28.4% higher tumor volume reduction with almost no metastatic nodules in the mouse model. Our data demonstrate that AA liposomes are safe, simple, and efficient, and thus in many situations may be used instead of conventional liposomes, having good potential for further clinical translational development.

Research Progress on Mechanism and Management of Adverse Drug Reactions of Anlotinib

Anti-angiogenesis therapy plays a vital role in the treatment of tumors, with anlotinib as its representative targeted drug. Anlotinib is a novel oral tyrosine kinase inhibitor (TKI) with inhibitory effects on tumor growth tumor angiogenesis. In Phase III clinical trials, anlotinib demonstrated better overall survival and progression-free survival than placebo in patients with advanced non-small cell lung cancer (NSCLC), and was approved for the first time as a third-line treatment for refractory advanced NSCLC. Going far beyond that, anlotinib has shown encouraging results in a variety of malignancies, including medullary thyroid carcinoma, renal cell carcinoma, gastric cancer and esophageal squamous cell carcinoma. Nevertheless, anlotinib has been subject to some controversy in terms of adverse events due to its widespread use. In this review, the mechanism of action, pharmacokinetic characteristics, adverse reactions in clinical use and management of anlotinib were summarized.

Palmar-plantar erythrodysesthesia syndrome resulting from toceranib phosphate in a dog with apocrine gland anal sac adenocarcinoma: a case report

An 11-year-old neutered male Miniature Poodle with a stage 3 apocrine gland adenocarcinoma was started on chemotherapy with toceranib phosphate after surgery. Beginning on day 10 of toceranib, the dog's foot pads became erythematous and hyperkeratinized. The dog complained of pain, inability to walk, depression, and loss of appetite. The symptoms resolved when toceranib was discontinued and reappeared when toceranib was resumed. Grade 3 palmar-plantar erythrodysesthesia was identified as an adverse event of toceranib based on the VCOG-CTCAE and Naranjo scale. Although very rare in veterinary medicine, clinicians should consider that palmar-plantar erythrodysesthesia can occur after toceranib administration.

The effect of chemotherapy and radiotherapy on stem cells and wound healing. Current perspectives and challenges for cell-based therapies

Cancers are part of the group of diseases that carry a high mortality rate. According to World Health Organization in 2020 reported 10 million deaths due to cancers. Treatment of oncological patients is focused on chemotherapeutic agents, radiology, or immunology. Surgical interventions are also an important aspect of treatment. The above methods contribute to saving the patients' health and lives. However, cancer treatment possesses side effects. Commonly observed complications are hair loss, mucositis, nausea, diarrhea, or various skin damage. To improve the quality of medical care for cancer patients, new methods of reducing side effects are sought. Strategies include the use of stem cells (SCs). Due to unlimited proliferation potential and differentiating abilities, SCs are used in the treatment of many disease entities, including wounds. One of the most used types of stem cells supposed adipose-derived mesenchymal stromal cells (AD-MSCs). Clinical trials confirm the application of AD-MSCs in wound healing. Furthermore, in vivo studies considered the utilization of AD-MSCs in radiation injury. The use of stem cells in cancer treatment still involves many questions, such as the impact of treatment on SCs' condition and oncological safety. However, development in regenerative medicine research may contribute to the use of stem cells in personalized medicine, customized for the patient. This could represent a breakthrough step in preventing the side effects of cancer therapies, including chronic wounds.

Capecitabine-induced hand-foot syndrome: A pharmacogenetic study beyond DPYD

AIM OF THE STUDY

Occurrence of hand-foot syndrome (HFS) during capecitabine treatment often results in treatment interruptions (26 %) or treatment discontinuation (17 %), and can severely decrease quality of life. In this study, we investigated whether single nucleotide polymorphisms (SNPs) in genes involved in capecitabine metabolism - other than DPYD - are associated with an increased risk for capecitabine-induced HFS.

METHODS

Patients treated with capecitabine according to standard of care were enrolled after providing written informed consent for genotyping purposes. Prospectively collected blood samples were used to extract genomic DNA, which was subsequently genotyped for SNPs in CES1, CES2 and CDA. SNPs and clinical baseline factors that were univariably associated with HFS with P ≤ 0.10, were tested in a multivariable model using logistic regression.

RESULTS

Of the 446 patients eligible for analysis, 146 (32.7 %) developed HFS, of whom 77 patients (17.3 %) experienced HFS ≥ grade 2. In the multivariable model, CES1 1165-33 C>A (rs2244613, minor allele frequency 19 %) and CDA 266 + 242 A>G (rs10916825, minor allele frequency 35 %) variant allele carriers were at higher risk of HFS ≥ grade 2 (OR 1.888; 95 %CI 1.075-3.315; P = 0.027 and OR 1.865; 95 %CI 1.087-3.200; P = 0.024, respectively).

CONCLUSIONS

We showed that CES1 1165-33 C>A and CDA 266 + 242 A>G are significantly associated with HFS grade 2 and grade 3 in patients treated with capecitabine. Prospective studies should assess whether this increased risk can be mitigated in carriers of these SNPs, when pre-emptive genotyping is being followed by dose adjustment or by alternative treatment by a fluoropyrimidine that is not substrate to CES1, such as S1.

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.

Oncologic emergencies and urgencies: A comprehensive review

Patients with advanced cancer generate 4 million visits annually to emergency departments (EDs) and other dedicated, high-acuity oncology urgent care centers. Because of both the increasing complexity of systemic treatments overall and the higher rates of active therapy in the geriatric population, many patients experiencing acute decompensations are frail and acutely ill. This article comprehensively reviews the spectrum of oncologic emergencies and urgencies typically encountered in acute care settings. Presentation, underlying etiology, and up-to-date clinical pathways are discussed. Criteria for either a safe discharge to home or a transition of care to the inpatient oncology hospitalist team are emphasized. This review extends beyond familiar conditions such as febrile neutropenia, hypercalcemia, tumor lysis syndrome, malignant spinal cord compression, mechanical bowel obstruction, and breakthrough pain crises to include a broader spectrum of topics encompassing the syndrome of inappropriate antidiuretic hormone secretion, venous thromboembolism and malignant effusions, as well as chemotherapy-induced mucositis, cardiomyopathy, nausea, vomiting, and diarrhea. Emergent and urgent complications associated with targeted therapeutics, including small molecules, naked and drug-conjugated monoclonal antibodies, as well as immune checkpoint inhibitors and chimeric antigen receptor T-cells, are summarized. Finally, strategies for facilitating same-day direct admission to hospice from the ED are discussed. This article not only can serve as a point-of-care reference for the ED physician but also can assist outpatient oncologists as well as inpatient hospitalists in coordinating care around the ED visit.

Association of Low Handgrip Strength with Chemotherapy Toxicity in Digestive Cancer Patients: A Comprehensive Observational Cohort Study (FIGHTDIGOTOX)

In the FIGHTDIGO study, digestive cancer patients with dynapenia experienced more chemotherapy-induced neurotoxicities. FIGHTDIGOTOX aimed to evaluate the relationship between pre-therapeutic handgrip strength (HGS) and chemotherapy-induced dose-limiting toxicity (DLT) or all-grade toxicity in digestive cancer patients. HGS measurement was performed with a Jamar dynamometer. Dynapenia was defined according to EWGSOP2 criteria (<27 kg (men); <16 kg (women)). DLT was defined as any toxicity leading to dose reduction, treatment delay, or permanent discontinuation. We also performed an exploratory analysis in patients below the included population’s median HGS. A total of 244 patients were included. According to EWGSOP2 criteria, 23 patients had pre-therapeutic dynapenia (9.4%). With our exploratory median-based threshold (34 kg for men; 22 kg for women), 107 patients were dynapenic (43.8%). For each threshold, dynapenia was not an independent predictive factor of overall DLT and neurotoxicity. Dynapenic patients according to EWGSOP2 definition experienced more hand-foot syndrome (p = 0.007). Low HGS according to our exploratory threshold was associated with more all-grade asthenia (p = 0.014), anemia (p = 0.006), and asthenia with DLT (p = 0.029). Pre-therapeutic dynapenia was not a predictive factor for overall DLT and neurotoxicity in digestive cancer patients but could be a predictive factor of chemotherapy-induced anemia and asthenia. There is a need to better define the threshold of dynapenia in cancer patients.

In Vitro Study of the Potential Role of Olive Oil Oleuropein in Modulating the 5-FU Cytotoxic Efficacy against the Tongue Squamous Cell Carcinoma

BACKGROUND: 5-fluorouracil (5-FU) is an anticancer drug used to inhibit the proliferation of many different tumor cells. Since severe side effects are associated with this drug, its combination with different natural compounds would allow the use of a significantly lower dose of 5-FU. Oleuropein (OLEU), has been shown to have inhibitory effects on various types of cancers. AIM: The main objective of the current study was to assess the cytotoxic effect of OLEU and the chemotherapeutic drug 5-FU on Human Tongue Carcinoma Cancer Cell Line (HNO-97) and Human Normal Oral Epithelial Cell Line (OEC) either independently or combinatory effect. MATERIALS AND METHODS: 3-(4,5- dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide (MTT) assay for cell viability, and half-maximal inhibitory concentration (IC50) was calculated. Flowcytometry for cell cycle analysis was performed. Also, in vitro scratch assay was done to assess the inhibitory effects of OLEU on the migration of cells.RESULTS: MTT assay study demonstrated that OLEU and 5-FU alone or in combinations have produced a significant inhibitory effect on both normal and cancer cell lines with a favorable impact for OLEU on cancer cell lines rather than the normal one. A significant increase in the cell inhibitory % was reported between the single and the combinations treated groups as compared to the non-treated control group. Cell cycle analysis via flowcytometry showed that OLEU had induced cell cycle arrest at G0/1 phase, decreased S phase and G2/M phase either independently or in combination for 24h and 48h when compared with a non-treated control group. A Scratch assay test showed that OLEU could induce delayed wound healing. CONCLUSIONS: The findings of the present study suggest that OLEU can exert an anti-cancer effect on HNO-97 and may have the potential for potentiation of 5-FU cytotoxic effects and reduction of its adverse effects. In addition, OLEU could inhibit cancer progression and expansion from the initial tumor.

Evaluation of chemotherapy-induced cutaneous side effects in cancer patients

BACKGROUND

Cutaneous side effects are commonly seen in cancer chemotherapy. As new chemotherapy drugs are developed, the frequency and the diversity of these cutaneous side effects increase. For this reason, identification and management of these side effects are an important part of the treatment of cancer patients. This study aimed to investigate mucocutaneous side effects of conventional chemotherapy and targeted therapy agents that are used in cancer patients.

METHODS

In this cross-sectional study, 231 cancer patients, who received single or combination chemotherapy at the oncology department of our hospital between 2013 and 2020, were retrospectively reviewed, and mucocutaneous side effects we evaluated.

RESULTS

The ages of the patients varied between 27 and 90 years with a median age of 60 years. Of the patients, 136 (58.9%) were women, and 95 (41.1%) were men. Combination chemotherapy was applied to 174 patients (71.9%). Mucocutaneous side effects were present in 558 patients. The most common side effect was alopecia, which was observed in 158 patients (65.6%). This was followed by mucositis (39.4%), hand-foot syndrome (35.3%), papulopustular rash (22%), dermatitis (18.3%), xerosis (14.1%), nail disorders (12%), and others.

CONCLUSIONS

Although chemotherapy-induced cutaneous side effects are not usually life-threatening, they may lead to the development of morbidity and discontinuance or termination of the treatment. Therefore, these side effects should be well managed to improve the quality of life of cancer patients.

Skin Microbiome and Treatment-Related Skin Toxicities in Patients With Cancer: A Mini-Review

The human skin hosts millions of bacteria, fungi, archaea, and viruses. These skin microbes play a crucial role in human immunological and physiological functions, as well as the development of skin diseases, including cancer when the balance between skin commensals and pathogens is interrupted. Due to the linkages between inflammation processes and skin microbes, and viral links to skin cancer, new theories have supported the role a dysbiotic skin microbiome plays in the development of cancer and cancer treatment-related skin toxicities. This review focuses on the skin microbiome and its role in cancer treatment-related skin toxicities, particularly from chemotherapy, radiation therapy, and immunotherapy. The current literature found changes in the diversity and abundance of the skin microbiome during cancer treatments such as radiation therapy, including lower diversity of the skin microbiome, an increased Proteobacteria/Firmicutes ratio, and a higher abundance of pathogenic Staphylococcus aureus. These changes may be associated with the development and severity of treatment-related skin toxicities, such as acute radiation dermatitis, hand-foot syndrome in chemotherapy, and immunotherapy-induced rash. Several clinical guidelines have issued potential interventions (e.g., use of topical corticosteroids, phototherapy, and non-pharmaceutical skin care products) to prevent and treat skin toxicities. The effectiveness of these promising interventions in alleviating treatment-related skin toxicities should be further tested among cancer patients.

Efficacy and Safety of Capecitabine for Triple-Negative Breast Cancer: A Meta-Analysis

Background

Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer with limited treatment options and poor prognosis. Capecitabine, as a novel adjuvant chemotherapy for TNBCs, remains controversial. Therefore, we conducted this meta-analysis to assess the efficacy and safety of capecitabine for early-stage TNBCs combined with neo-/adjuvant chemotherapy.

Methods

We searched Medline, Embase, Web of Science, and Cochrane databases updated on Mar 18, 2022 for relevant RCTs. In all, 11 RCTs with 5,175 patients were included. We used hazard ratios (HRs) and odds ratios (ORs) to assess the differences between disease-free survival (DFS), overall survival (OS), and adverse events.

Results

Our study demonstrated significance differences in both DFS and OS (DFS: HR=0.77; 95% CI 0.68–0.86; OS: HR=0.73, 95% CI 0.63–0.85). In subgroup analysis, the lower dosage group showed higher DFS (HR=0.79, 95% CI 0.69–0.91), higher frequency (HR=0.72, 95%CI 0.62–0.83), and adjuvant chemotherapy (HR=0.74, 95% CI 0.65–0.84). However, capecitabine was also associated with a higher risk of diarrhea (OR=3.10, 95% CI 2.32–4.15), hand–foot syndrome (OR=25.79, 95% CI 15.32–43.42), and leukopenia (OR=2.08, 95% CI 1.13–3.84).

Conclusion

The addition of capecitabine to early-stage TNBC patients receiving standard adjuvant chemotherapy showed significant DFS and OS improvement with tolerable adverse events. The lower dosage and higher frequency of capecitabine combined with adjuvant chemotherapy demonstrated a better survival outcome.

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.

Analysis of drug-induced hand-foot syndrome using a spontaneous reporting system database

Purpose

The aim of our study was to assess the clinical features of hand-foot syndrome (HFS) associated with certain systemic chemotherapeutic drugs in a real-world setting using the Japanese Adverse Drug Event Report (JADER) database.

Methods

HFS was defined using the preferred terms from the Medical Dictionary for Regulatory Activities. We used several indices, such as the reporting odds ratios (RORs) at 95% confidence interval (CI), the time-to-onset profile of HFS, and cluster analysis.

Results

Of 646,779 reports (submission period: April 2004 to September 2020), 1814 reported HFS events. The RORs (95% CI) for axitinib, capecitabine, lapatinib, regorafenib, sorafenib, and sunitinib were 14.9 (11.1-20.1), 54.6 (49.2-60.6), 130.4 (110.7-153.6), 63.3 (55.2-72.6), 29.0 (25.8-32.7), and 13.9 (11.7-16.5), respectively. The analysis of time-to-onset profiles revealed that the median values (interquartile range: 25.0-75.0%) of drug-induced HFS caused by capecitabine, cisplatin, docetaxel, everolimus, regorafenib, sorafenib, and trastuzumab were 21.0 (13.0-42.0), 15.0 (10.0-82.0), 6.0 (3.0-25.0), 86.5 (67.0-90.5), 9.0 (6.0-14.0), 9.0 (6.0-14.0), and 70.0 (15.0-189.0) days, respectively. The number of clusters was set to 4. Among these, one cluster, which included capecitabine, regorafenib, and lapatinib, exhibited a higher reporting ratio and ROR of drug-induced HFS than other drugs.

Conclusions

The RORs and results of time-to-onset analysis obtained in this study indicated the potential risk of HFS associated with chemotherapeutic drugs. Our results suggest that health care professionals must be aware of the potential onset of drug-induced HFS with docetaxel, regorafenib, and sorafenib for at least 4 weeks; therefore, careful observation is recommended.

Plain Language Summary

Elucidation of the relationship between cancer drugs and risk of hand-foot syndrome: Purpose: Hand-foot syndrome (HFS) is an adverse effect of some cancer drugs, which is characterized by symptoms such as redness, swelling, blistering, and pain in the area of palms and soles. HFS reduces the quality of life of patients and can sometimes interfere with anticancer treatment plans. It is important to understand the clinical manifestations of HFS and gain knowledge that will allow for early intervention by clinicians.Methods: In this study, we used a large-scale side effect database of real-world cases for a comprehensive investigation of anticancer-drug-induced HFS. The database contained 646,779 adverse event reports from April 2004 to September 2020; among which, we identified 1814 HFS events. Using these data, we could obtain information on the relationship between 19 types of anticancer drugs and HFS, and the onset time of HFS and HFS prognosis related to each anticancer drug. Results: Our results suggest that clinicians should monitor the risk of HFS with docetaxel, regorafenib, and sorafenib for at least the first 4 weeks after drug administration. Conclusion: These findings are crucial for improving the management of the adverse effects caused by anticancer drugs.

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.

P38 MAPK, NF-κB, and JAK-STAT3 Signaling Pathways Involved in Capecitabine-Induced Hand-Foot Syndrome via Interleukin 6 or Interleukin 8 Abnormal Expression

Hand-foot syndrome (HFS) is a major adverse reaction to capecitabine (CAP). The exact pathogenesis of this disease remains unclear. In this study, metabolomics combined with cell RNA sequencing was used to study the mechanisms of CAP-induced HFS. The murine model of HFS was constructed by intragastric administration of CAP or its metabolites. Quantitative reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assays were used to verify the mechanisms. Metabolomics showed the phosphatidylinositol signaling pathway and amino acid and fatty acid metabolism to be the major metabolic alterations related to the occurrence of HFS. Transcriptomics profiles further revealed that the cytokine-cytokine receptor interaction, IL17 signaling pathway, Toll-like receptor signaling pathway, arachidonic acid metabolism, MAPK signaling pathway, and JAK-STAT3 signaling pathway were the vital steps in skin toxicity induced by CAP or its metabolites. We also verified that the inflammation mechanisms were primarily mediated by the abnormal expression of interleukin (IL) 6 or IL8 and not exclusively by COX-2 overexpression. Finally, the P38 MAPK, NF-κB, and JAK-STAT3 signaling pathways, which mediate high levels of expression of IL6 or IL8, were identified as potential pathways underlying CAP-induced HFS.

Predictors of oral chemotherapy adherence at home among Chinese cancer patients: An observational prospective study

AIMS AND OBJECTIVES

To explore whether medication non-adherence experience, readiness for hospital discharge, financial toxicity and symptoms predicted oral chemotherapy adherence at home for Chinese cancer patients.

BACKGROUND

Oral chemotherapy adherence is critical to determine the treatment efficacy among cancer patients. Identifying predictors before discharge from hospital based on transition theory could assist healthcare providers to improve oral chemotherapy adherence at home.

DESIGN

An observational prospective study.

METHODS

Between October 2018 and December 2019, self-reported questionnaires were used to collect data among 151 cancer patients with oral chemotherapy at home. At discharge, baseline data of patient-perceived readiness for hospital discharge, financial toxicity and non-adherence experience were collected, while symptoms and adherence of oral chemotherapy at home were collected after finishing one cycle of oral chemotherapy at home (21 days, the first 14 days received oral chemotherapy). Regression analyses were performed for the predictors' explorations. The STROBE guidelines were followed.

RESULTS

Among 151 participants with oral chemotherapy at home, 30.46% of patients reported medication non-adherence experience at discharge and 82.12% of patients reported adherence to oral chemotherapy at home. Patients with non-adherence experience at discharge were 5.4 times more likely to being non-adhered to oral chemotherapy at home. Numbness were the most frequent and severe symptoms during at home, patients with numbness were 6.6 times more likely to being non-adhered to oral chemotherapy. Although patients reported high level of readiness for discharge and financial toxicity at discharge, which did not predicted oral chemotherapy adherence at home.

CONCLUSIONS

Patients with medication non-adherence experience at discharge and symptom of numbness from oral chemotherapy suggested a higher risk of oral chemotherapy non-adherence at home.

RELEVANCE TO CLINICAL PRACTICE

Preventive interventions should focus on patients with previous medication non-adherence experience at discharge and experiencing numbness to promote oral chemotherapy adherence.

Performance of capecitabine in novel combination therapies in colorectal cancer

Colorectal cancer is one of the most common cancers throughout the world, and no definitive cure has ever been found. Perhaps a new insight into the effectiveness of chemotherapy drugs could help better treat patients. Targeted therapies have significantly improved the median overall survival of colorectal cancer patients. One of the standard chemotherapy regimens used for colorectal cancer is capecitabine, which is important in monotherapy and combination therapies. Capecitabine, with other chemotherapeutic agents (irinotecan, oxaliplatin, perifosine, 17-allylamino-17-demethoxygeldanamycin, aspirin, celecoxib, statins, quinacrine, inositol hexaphosphate and inositol, cystine/theanine, curcumin, and isorhamnetin), and biological ones (antibodies) plays an important role in the inhibition of some signaling pathways, increasing survival, reducing tumor growth and side effects of capecitabine. However, some drugs, such as proton pump inhibitors, are negatively related to capecitabine; therefore, the purpose of this work is to review and discuss the performance of capecitabine combination therapies in colorectal cancer.

Efficacy and safety profile of combining programmed cell death-1 (PD-1) inhibitors and antiangiogenic targeting agents as subsequent therapy for advanced or metastatic non-small cell lung cancer (NSCLC)

Background

Previous studies have demonstrated that PD‐1 inhibitors are effective in the treatment of advanced or metastatic non‐small cell lung cancer (NSCLC). However, whether the combination of PD‐1 inhibitors and antiangiogenic agents benefit advanced NSCLC patients as subsequent therapy remains unknown. In this study, we retrospectively reviewed the efficacy and safety profile of this combination strategy as subsequent therapy for NSCLC patients in a real‐world setting.

Methods

A total of 30 patients with advanced NSCLC, who progressed after at least two cycles of platinum‐based chemotherapy or targeted therapy and subsequently received combination therapy with a PD‐1 inhibitor and antiangiogenic agent, were included in this study. The safety profile and efficacy were also investigated.

Results

At the time of a median follow‐up period of 10.7 months, 28 patients had experienced progression of disease and 16 patients had died. The median progression‐free survial (mPFS) was 5.0 months (95% confidence interval [CI]: 3.179–6.821), and the median overall survival (mOS) was 14.3 months (95% CI: 8.912–19.659). The objective response rate (ORR) and the disease control rate (DCR) were 10.3% and 72.4%, respectively (0 complete remission, three partial responses and 18 stable disease in 29 patients with measurable lesions). Patients with PD‐L1 expression of at least 1% of tumor cells (n = 5) had relatively longer mPFS compared to those with PD‐L1‐negative tumors (n = 14), (11.6 months vs. 3.7 months). Treatment was suspended in two patients due to grade 3 immune‐related pneumonia and pancreatitis, respectively. No novel adverse events (AEs) or grade 4 AEs were observed.

Conclusions

A combination of PD‐1 inhibitors and antiangiogenic targeting agents may be beneficial for patients with advanced or metastatic NSCLC as subsequent treatment, especially for patients with PD‐L1 protein expression positive, and treatment is well tolerated.

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. Trial registration This study was registered as a clinical trial at www.clinicaltrials.gov (NCT03030508).

Efficacy of topical Lawsonia inermis L. (Henna) hydrogel in fluorouracil-induced hand-foot syndrome: a pilot randomized double-blind placebo-controlled clinical trial

PURPOSE

Hand-foot syndrome (HFS) is a frequent dose-limiting adverse reaction of fluoropyrimidine drugs like capecitabine and 5-flourouracil (5-FU) in breast and gastrointestinal cancers. It has been shown that conventional application of Lawsonia inermis L. (Henna) is effective in ameliorating of the skin lesions. To increase the patient compliance, in this study we formulated a standardized topical hydrogel (H.gel) containing the hydroalcoholic extract (10%) of Henna and evaluated its clinical efficacy for the management of fluorouracil associated HFS.

MATERIAL AND METHODS

The topical dosage form was standardized based on its Lawsone content. Eighteen patients suffering from HFS were randomized to receive H.gel and the placebo four times a day for 2 weeks. At the baseline and at the end of the trial, HFS grades were determined.

RESULTS AND CONCLUSIONS

Allergic reactions following administration of H.gel were observed in one patient, while no serious adverse events occurred in the others. No statistically significant differences between two arms were observed at the baseline (p-value = 0.133), after treatment (p-value = 0.590) and grade differences (p-value = 0.193). The applied hydrogel showed less efficacy compared to the traditional method of using Henna, meaning that Lawsone may not be a good indicator for standardizing the topical dosage form.

Therapeutic Ultrasound for Chemotherapy-Related Pain and Sensory Disturbance in the Hands and Feet in Patients With Colorectal Cancer: A Pilot Randomized Controlled Trial

CONTEXT

This proof-of-concept trial was undertaken as a first step in exploring the clinical benefit of therapeutic ultrasound for pain and sensory disturbance in patients with colorectal cancer.

OBJECTIVES

The aim of this study was to determine the feasibility and preliminary efficacy of adding therapeutic ultrasound to a home-based therapeutic exercise program (current standard of care) for patients presenting with oxaliplatin-related pain and sensory disturbance in the hands and feet.

METHODS

Thirty-one colorectal cancer patients with presenting symptoms of peripheral sensory neuropathy, based on a physician-rated grade 1, 2, or 3 on the National Cancer Institute Common Terminology Criteria for Adverse Events for sensory and motor neuropathy, were enrolled in the trial. Patients were randomized to either 10 sessions of ultrasound therapy intervention over two-week period (continuous ultrasound at an intensity of 0.7 to 0.8 w/cm², and frequency of 3 MHz for 5 minutes) plus standard care (n = 16) or to standard care alone (n = 15). The feasibility of therapeutic ultrasound was determined by the recruitment rate, participants' adherence to the intervention, and the study completion rates. Assessments of pain, sensory disturbance, sensation, and balance were conducted at baseline, two and six weeks.

RESULTS

We achieved a recruitment rate of 84%, an adherence rate of 100% to the intervention, and a completion rate of 100%. Adding therapeutic ultrasound to standard care resulted in a statistically and clinically significant improvement in symptoms of pain and sensory disturbance (P = 0.003) at two weeks; however, no significance difference between the groups was found at the six-week follow-up.

CONCLUSIONS

The findings of this proof-of-concept study support the feasibility of the therapeutic ultrasound in addition to standard care as an intervention for colorectal cancer patients with oxaliplatin-related pain and sensory disturbance in the hands and feet. The findings warrant a large-scale placebo-controlled trial.

Use of omeprazole, the proton pump inhibitor, as a potential therapy for the capecitabine-induced hand-foot syndrome

Hand-foot syndrome (HFS), also known as palmar-plantar erythrodysesthesia (PPE), is a major side effect of capecitabine. Although the pathogenesis of HFS remains unknown, some studies suggested a potential involvement of inflammation in its pathogenesis. Proton pump inhibitors (PPIs) have been reported to have anti-inflammatory effects. In this study, we investigated the ameliorative effects of omeprazole, a PPI on capecitabine-related HFS in mice model, and a real-world database. Repeated administration of capecitabine (200 mg/kg, p.o., five times a week for 3 weeks) increased fluid content, redness, and tumor necrosis factor (TNF)-α substance of the mice hind paw. Co-administration of omeprazole (20 mg/kg, p.o., at the same schedule) significantly inhibited these changes induced by capecitabine. Moreover, based on the clinical database analysis of the Food and Drug Administration Adverse Event Reporting System, the group that has used any PPIs had a lower reporting rate of capecitabine-related PPE than the group that has not used any PPIs. (6.25% vs. 8.31%, p < 0.0001, reporting odds ratio (ROR) 0.74, 95% confidence interval (CI) 0.65-0.83). Our results suggest that omeprazole may be a potential prophylactic agent for capecitabine-induced HFS.

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.

Reactive Oxygen Species-Mediated Inflammation and Apoptosis in Hand-Foot Syndrome Induced by PEGylated Liposomal Doxorubicin

BACKGROUND

Doxil® (PEGylated liposomal doxorubicin, PLD) has been widely used in cancer treatment due to its excellent therapeutic efficacy, but it can simultaneously cause severe adverse effects such as hand-foot syndrome (HFS). To date, the pathophysiologic mechanism of HFS development induced by PLD administration has not been well understood.

MATERIALS AND METHODS

The histological features of skin lesion in PLD-induced HFS model were characterized by hematoxylin and eosin (H&E) staining and picrosirius red staining, and the induction of inflammation and apoptosis in the epidermal layer was detected by immunohistochemical and TUNEL staining. Moreover, the generation of reactive oxygen species (ROS) was determined to elucidate the potential mechanism of skin lesion in the development of HFS.

RESULTS

The administration of PLD has been demonstrated to induce the histological damage of skin tissues including the destruction of collagen fibers and the induction of severe inflammation and apoptosis of epidermal cells. The mechanism was probably attributed to the accumulation of PLD in the skin tissues during the long-term circulation and further the induction of ROS to cause the oxidative damage of keratinocytes owing to the sustained release of doxorubicin from PLD.

CONCLUSION

The ROS generation induced by the administration of PLD has been identified to be a crucial factor in the development of HFS, which could be used as a potential therapeutic target to alleviate the HFS symptom of PLD administration.

Pegylated liposomal doxorubicin in patients with epithelial ovarian cancer

OBJECTIVE

To evaluate the efficacy and safety of PLD in treating of in patients who experience epithelial ovarian, fallopian tubal, and peritoneal cancer progression within 12 months after the first-line platinum-based therapy.

METHODS

This was an open-label, single-arm and multicenter clinical trial. The ORR was the interim primary objective, and the DCR, AEs and QOL were the secondary objectives. The impact of factors on efficacy outcomes, the change trend of CA125 and the artificial platinum-free interval were exploratory endpoints.

RESULTS

Totally, 115 patients were enrolled in this study and included in the ITT population. Moreover, 101 patients were included in the safety population. The median follow-up time was 4 months (IQR 2-6). In the ITT population, the confirmed ORR was 37.4% (95% CI, 28.4-46.4%), and the DCR was 65.2% (95% CI, 56.4-74.1%). The previous response status to platinum-based chemotherapy and baseline CA125 levels were significantly correlated with the ORR. The ORR was significantly higher in patients with a CA125 decrease after the first cycle than in the patients with a CA125 increase. The most common grade 3 or higher AE was hand-foot syndrome (3 [3.0%] of 101 patients). No statistically significant differences existed between the baseline and the postbaseline questionnaires.

CONCLUSIONS

For patients who experience platinum-resistant and platinum-refractory relapse, the use of PLD may be acceptable because of the associated satisfactory efficacy, low frequency of AEs and high patient QOL. Moreover, a low CA125 level at baseline and a reduction in CA125 after the first cycle are predictive factors for satisfactory efficacy.

Liposomal doxorubicin-related palmar-plantar erythrodysesthesia (hand-foot syndrome): a case report

Hand–foot syndrome (HFS) is a skin toxicity that occurs in areas of compressed skin. HFS manifests mainly in insensitive palms and the soles of the feet or in erythematous areas on the extremities caused by chemotherapy, which may be related to the dosage. This paper reports a case of HFS caused by liposomal doxorubicin. A 64-year-old Asian woman presented with severe erythema, ulceration, pruritus, and edema-related pain in her back, hands, and feet after receiving four cycles of liposomal doxorubicin. Clinicians and a pharmacist analyzed and evaluated the patient’s adverse reactions. After symptomatic treatment and patient education, her HFS symptoms were significantly relieved. The purpose of this study was to raise clinical awareness regarding adverse events following liposomal doxorubicin injection, and to provide new ideas for the clinical treatment of these adverse events.

Maintenance Chemotherapy with S-1 Following SOX Regimen Chemotherapy Improves Prognosis of Stage 3 Gastric Cancer After D2 Gastrectomy: A 5-Year Analysis

Objective

To assess the effectiveness and safety of treatment consisting of maintenance chemotherapy (MCT) with S-1 following S-1 plus oxaliplatin (SOX) chemotherapy for stage 3 gastric cancer (GC) after D2 gastrectomy.

Methods

In this retrospective study, we enrolled 255 patients with stage 3 GC who underwent D2 gastrectomy between February 2011 and May 2014. The SOX regimen chemotherapy was administrated to all of the patients as adjuvant therapy. The SOX regimen consisted of S-1 (for patients with a body surface area [BSA] of less than 1.25 m², 80 mg/d; 100 mg/d for BSA=1.25 m²- <1.5 m², and 120 mg/d for BSA≥1.5 m², in 2 divided doses for 14 d) and oxaliplatin (130 mg/m² given on Day 1), repeated every 21 d for 8 cycles. Following SOX chemotherapy, 122 of these patients received maintenance chemotherapy (the MCT group) with S-1, whereas 133 patients (the control group) received no MCT. The MCT consisted of S-1 (80, 100, or 120 mg daily based on BSA, in 2 divided doses for 14 d), repeated every 21 d for 8 cycles at most. The chemotherapy was discontinued if unacceptable toxicity or disease progression occurred or upon the request of the patient. All cases were followed up, and overall survival (OS), recurrence-free survival (RFS), and toxicities were compared.

Results

The MCT group exhibited a distinctly higher 5-year OS (P=0.0425) and RFS (P=0.0479) than those of the control group. The incidence of hand-foot syndrome was markedly greater in the MCT group (P=0.0026). No toxicity-related death occurred.

Conclusion

Maintenance chemotherapy with S-1 following the SOX regimen chemotherapy provides significant survival benefit for stage 3 GC after D2 gastrectomy.

Oleosomes Encapsulating Sildenafil Citrate as Potential Topical Nanotherapy for Palmar Plantar Erythrodysesthesia with High Ex vivo Permeation and Deposition

Palmar plantar erythrodysesthesia (PPE) is a commonly reported skin toxicity of chemotherapeutic agents that significantly affects patients' quality of life. PPE is described as inflammation, swelling, and even cracks and ulcers in the skin of palms and soles of the feet. Conventional treatment includes topical creams, analgesics, or corticosteroids. However, serious cases are not responding to these medications. PPE has been reported to cause drug cessation or dose reduction if not properly treated. Sildenafil citrate (SC) has a well-documented activity in wound healing through improving blood supply to the affected area. However, SC has poor physicochemical properties limiting its transdermal permeation and deposition. This research endeavored to elaborate novel vesicular system with natural components, phospholipids and oleic acid, loaded with sildenafil citrate for topical management of PPE. Sildenafil-loaded oleosomes were prepared using modified ethanol injection method. Optimized oleosomes had nanometric particle size (157.6 nm), negative zeta potential (- 85.2 mv), and high entrapment efficiency (95.56%). Ex vivo studies on human skin revealed that oleosomes displayed 2.3-folds higher permeation and 4.5-folds more deposition through the human skin compared to drug suspension. Results endorsed SC oleosomes as suitable topical treatment of PPE providing ameliorated sildenafil permeability in addition to acting as a reservoir for gradual release of the drug.

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.

Skin Toxicity: Clinical Summary of the ONS Guidelines™ for Cancer Treatment-Related Skin Toxicity

Cancer treatment-related skin toxicities are a frequent and distressing side effect of antineoplastic therapies, especially chemotherapy and targeted therapies. Skin toxicities associated with these therapies can include rashes, hand-foot skin reaction, hand-foot syndrome, and hair loss. These symptoms cause not only physical pain and discomfort but also psychological distress, and they can become a stigma of the patient's cancer diagnosis. Skin toxicities can cause treatment delays and even discontinuation, which affects clinical outcome. The prevention of toxicities and effective, early management can reduce the risk for distress and treatment delays.

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.

Anlotinib as a molecular targeted therapy for tumors

Angiogenesis has an essential role in tumor growth and metastasis, and blocking this pathway has been a successfully utilized strategy in the clinical treatment of cancer. Anlotinib (AL3818) is a novel oral receptor tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor 2 and 3, fibroblast growth factor 1-4, platelet-derived growth factor receptor α and β, c-Kit and Ret. Anlotinib exerts inhibitory effects on tumor growth and angiogenesis and received its first approval as a third-line treatment for refractory advanced non-small-cell lung cancer in May 2018 and its second approval as a second-line treatment for advanced soft-tissue sarcoma in June 2019 in the People's Republic of China. Anlotinib has encouraging efficacy and a manageable and tolerable safety profile in a broad range of malignancies, including medullary thyroid cancer, renal cell cancer, gastric cancer and esophageal squamous cell carcinoma. In the present review, the preclinical and clinical trials of anlotinib were summarized with a focus on safety evaluation and adverse event management.

Oxaliplatin-Induced Lhermitte's Sign in Gastric Cancer

A 64-year-old Japanese man with no significant medical history presented with epigastric discomfort of 2-weeks' duration. He was diagnosed with metastatic HER2-positive gastric cancer. Chemotherapy with capecitabine, oxaliplatin, and trastuzumab was initiated. During the eighth cycle, he suddenly complained of electric shock-like pain in both legs upon neck flexion, consistent with Lhermitte's sign. Oxaliplatin was discontinued, and Lhermitte's sign resolved after 3 months. Neurotoxicity is commonly observed in platinum-based chemotherapy, but Lhermitte's sign is rare. This is the first report of oxaliplatin-induced Lhermitte's sign in a gastric cancer patient.

Apatinib-induced Grade 3 hand-foot syndrome in advanced lung adenocarcinoma successful treated with thalidomide: A case report

Hand-foot syndrome (HFS) is a specific cutaneous toxicity caused by a variety of antitumor drugs. The most common drugs include capecitabine, pegylated liposomal doxorubicin and fluorouracil (PLD), tyrosine kinase inhibitor. It is a dose-limiting cutaneous toxicity of these drugs. We reported an advanced lung adenocarcinoma female patient, who developed a Grade 3 HFS after a third-line treatment with apatinib of 250 mg for 10 days, the patient developed intolerable pain with pruritus. Large erythema on the skin of the hand, with local ulceratio, exudation, and desquamation of cutaneous lesions. After treatment with 100 mg of thalidomide every night for 1 week, the patient's HFS was significantly relieved, and the duration of the remission was about 2 months, which not only significantly improved the patient's quality of life, but also maintained the antitumor strength.

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.
