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

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).
CONCLUSIONS: 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.

BACKGROUND: Capecitabine (Xeloda®) is a cytotoxic, antimetabolite chemotherapeutic agent. Its most common adverse events are diarrhea, hand-foot syndrome (HFS), hyperbilirubinemia, hyperpigmentation, fatigue, abdominal pain, and other gastrointestinal effects. HFS or palmar-plantar erythrodysesthesia (PPE) is an adverse reaction resulting from therapy with chemotherapeutic agents, classified into three degrees. Hyperpigmentation, as an adverse effect of capecitabine, can occur in different locations and with different patterns. The skin, nails and oral mucosal membrane can be affected.
OBJECTIVE: The objective of this study was to report and discuss oral hyperpigmentation associated with HFS caused by the use of capecitabine, which is still poorly described in the literature.
METHODS: A literature review was carried out using the online databases PubMed, Scielo, BVS, Lilacs, Medline, BBO and Google Scholar, associating the descriptors \"Capecitabine\", \"Pigmentation Disorders\", \"Oral mucosa\", \"Cancer\" and \"Hand-Foot Syndrome\", which were related and used to exemplify, discuss and report the exposed clinical case.
RESULTS: This case report corroborates the literature regarding the incidence in females and black skin persons like this patient who was affected by HFS when undergoing antineoplastic therapy with capecitabine and presented hyperpigmentation of the hands, feet and oral mucosa. On the oral mucosa, the hyperpigmented spots were diffuse, showing a blackish color and irregular edges. Their pathophysiology remains unknown.
CONCLUSIONS: Few articles citing capecitabine-associated pigmentation.
CONCLUSIONS: It is hoped that this study may contribute to the identification and correct diagnosis of hyperpigmentation in the oral cavity, as well as call attention to the adverse effects related to capecitabine.

Chemotherapy drugs can be responsible of several side effects such as hand-foot syndrome (HFS). This syndrome is also called \"palmar-plantar erythrodysesthesia\" and \"acral erythema.\" Without proper management, it can deteriorate the quality of life of a patient, leading to temporary or definitive stop of chemotherapy.
To identify the epidemiological and clinical characteristics of patients, the risk factors for occurrence and worsening of this syndrome, and the drugs most likely to be responsible of HFS.
Our study was retrospective, including 42 patients with HFS secondary to a chemotherapy drug. These cases were notified to the National Center of Pharmacovigilance over 7 years. The severity of HFS has been classified according to the NCI-CTCAE v4.0 classification.
Our population was composed of 40 women and 2 men. The mean age was 51 years. Docetaxel was the main drug associated with this adverse effect. Hands were involved in all cases and were sometimes associated with other skin surfaces apart from feet. Erythema of the hands and/or feet was present in all patients; it was associated with edema in more than half of the cases. The distribution of different grades according to the NCI-CTCAE classification among the patients was almost equal: 28% Grade 1, 36% Grade 2, and 36% Grade 3. HFS occurred mainly after the first course of chemotherapy with a mean period of 3-4 days. The regression of HFS occurred more rapidly for Grade 1 and Grade 2 compared with Grade 3, especially when assisted by symptomatic treatment. The recurrence rate of HFS for those patients with decreased doses, spacing of cures, and/or symptomatic and prophylaxis treatment was 25%.
An early detection of HFS, associated with preventive measures, enables patients to continue the chemotherapy.

BACKGROUND: Capecitabine is frequently used alone or combined with other chemotherapy agents for the treatment of metastatic breast cancer in relapsed patients.
OBJECTIVE: The objective of this meta-analysis is to evaluate the effectiveness and safety of capecitabine monotherapy versus combination in the treatment of metastatic breast cancer patients pretreated with anthracycline and taxane.
METHODS: Eligible randomized controlled trials examining the efficacy and safety of capecitabine alone compared to capecitabine combination were systematically searched. Progression-free survival (PFS), overall survival (OS), overall response rate (ORR), and grades 3-4 drug-related adverse events were the outcomes assessed.
RESULTS: A total of 6,714 patients of 9 trials were involved in the pooled analysis. Our findings demonstrated that capecitabine combination is significantly superior to capecitabine monotherapy in improving PFS (hazard ratio [HR] 1.32, 95% CI 1.13-1.54, p < 0.0001) and ORR (risk ratio [RR] 0.67, 95% CI 0.54-0.83, p < 0.001), but it was insignificant in OS (HR 1.09, 95% CI 0.98-1.22, p = 0.12). On the other hand, the incidence of non-hematological adverse events such as hand-foot syndrome and diarrhea was lower in capecitabine combination compared to capecitabine monotherapy.
CONCLUSIONS: Capecitabine-based combination chemotherapy showed superiority over capecitabine monotherapy in terms of PFS and ORR, with no significant difference in OS. Non-hematological adverse effects such as hand-foot syndrome were fewer with a combination regimen. However, hematological adverse events were fewer with capecitabine monotherapy regimen.

BACKGROUND: Breast cancer patients may experience an increased chance of survival with adjuvant chemotherapy. However dermatologic adverse effects can cause major discomfort due to physical or cosmetic problems. This study aims to describe dermatologic complications in breast cancer patients during chemotherapy.
METHODS: This longitudinal prospective observational study included data on women with non-metastatic breast cancer whom were treated with AC-T protocol (anthracycline, cyclophosphamide, and taxane) adjuvant chemotherapy and consecutively enrolled during two years. The study was performed in an educational and tertiary referral center. The patients\' information including age, body mass index (BMI), past medical history, and different dermatologic complications were collected for all participants.
RESULTS: Of 190 enrolled women, all patients experienced alopecia, which occurred in 131 patients (68.9%) after the first cycle. Skin, mucosal, and nail involvement were respectively seen in 46 (24.2%), 51 (26.8%), and 86 (45.2%) cases. Cutaneous complications were observed mainly between the third and sixth chemotherapy cycles. Palmoplantar erythema and palmoplantar dysesthesia were the most common cutaneous complications. Dermatologic adverse effects were significantly more frequent in the patients with an underlying disease.
CONCLUSIONS: These findings suggest that dermatologic adverse effects of adjuvant chemotherapy are common and could be induced by all components of AC-T regimen. These complications should be skillfully managed to increase patients\' comfort.

Hand-foot syndrome (HFS) is a common skin toxicity of traditional chemotherapies. Some studies showed that HFS has an association with progression-free survival (PFS) and the overall survival (OS). So far, there is not available any systematic literature reviews or meta-analysis aimed to assess the associations between HFS, PFS and OS. For this reason, this study aims to quantitatively summarize, critically review, and interpret the recent literature related to the associations between HFS and efficacy of chemotherapy in terms of PFS and OS. Queries shaped by PICOM framework, a systematic search of three electronic databases (PubMed, Scopus, and Science Direct) was carried out for the period between January 2010 and December 2017. Quantitative data pooling was based on the calculation of Hazard Ratio (HR) with 95% Confidence Interval (95% CI) for the OS and PFS associated to the presence of HFS, through the data of original publications. Five papers were included in this systematic review for the quantitative data pooling. Patients with HFS showed improved PFS (HR = 0.532 [0.431-0.656]; p = 0.000) and improved OS (HR = 0.522 [0.427-0.638]; p = 0.000). HFS causes a reduction of compliance with oncology treatments. Healthcare providers should use this result as a trigger to foster patients\' coping and the one of their family caregivers, enhancing their adherence to cancer treatments.

Hand-foot syndrome (HFS) is the main side effect of capecitabine and affects the compression zones of the body such as the palms and soles, causing numbness, paresthesias, skin swelling or erythema, scaling, chapping, hard nodule-like blisters, and severe pain. Loss of fingerprints is also observed in some cases. Severe cases of HFS are common in the review of clinical reports. However, loss of fingerprints has not received significant attention. Two reported cases of loss of fingerprints in The New England Journal of Medicine and The BMJ have drawn attention to this side effect of capecitabine. Loss of fingerprints has a serious impact on patients\' daily life, especially on personal identification. This report describes a patient who lost her fingerprints during the early stage of chemotherapy. Our aim is to draw the medical profession\'s attention to this problem.

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

BACKGROUND: Vemurafenib has been linked to dermatological adverse events in patients with melanoma, including an increased risk of rash, cutaneous squamous cell carcinoma, photosensitivity reaction and keratoacanthoma. However, there has been no systematic attempt to assess the dermatological toxicity data of vemurafenib associated with melanoma treatment.
OBJECTIVE: To evaluate the point prevalence of dermatological toxicities associated with vemurafenib treatment in patients with melanoma.
METHODS: Searches were conducted of the electronic databases PubMed and EMBASE and of conference abstracts published by the American Society of Clinical Oncology. Eligible studies included prospective clinical trials and expanded-access programmes (i.e. outside a clinical trial) of patients with melanoma assigned to vemurafenib treatment. Outcomes included prevalence of dermatological toxicities treated with vemurafenib. Statistical analyses were performed using the R2.8.1 meta package.
RESULTS: In total, 11 studies comprising 4197 patients were included in the meta-analysis. For patients assigned to vemurafenib, the overall prevalence of all-grade cutaneous squamous cell carcinoma (cSCC) was 18.00% (95% CI 12.00-26.00%), rash 45.00% (95% CI 34.00-57.00%), photosensitivity reaction (PR) 30.00% (95% CI 23.00-38.00%), keratoacanthoma (KA) 10.00% (95% CI 6.00-15.00%) and hand-foot skin reaction (HFSR) 9.00% (95% CI 4.00-20.00%), while the prevalence of high-grade events was: cSCC 16.00% (95% CI 11.00-23.00%), rash 12.00% (95% CI 3.00-38.00%), PR 4% (95% CI 2.00-8.00%) and KA 6.00% (95% CI 5.00-7.00%).
CONCLUSIONS: The most frequent dermatological toxicities associated with vemurafenib treatment in patients with melanoma were cSCC, rash, PR and KA. These data may be useful for estimation of the efficacy and safety of the drug during clinical treatment and for reducing the prevalence of adverse reactions to vemurafenib treatment in patients with melanoma.
