Discoloration and Dilemma: A Case Report of Hand-Foot Syndrome Associated With Capecitabine Use

This case highlights the occurrence of hand-foot syndrome due to the use of an antimetabolite group of drugs, capecitabine, which was used in the chemotherapy of a 56-year-old male patient who was diagnosed with rectosigmoid carcinoma. The patient was diagnosed with rectosigmoid carcinoma two months ago and underwent laparoscopic lower anterior resection and colorectal anastomosis. Subsequently, the patient commenced chemotherapy treatment with a combination of oxaliplatin and capecitabine. The patient presented to us with complaints of loose stools for the past three days, and discoloration of the palms, soles, and tongue was noted and subjected to a biopsy, which revealed features compatible with chronic, nonspecific dermatitis. The occurrence of such palmar-plantar erythrodysesthesia with capecitabine is yet to be extensively studied.

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.

Loss of Fingerprints as a Side Effect of Capecitabine Therapy: Case Report and Literature Review

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.

Herbal medicine for hand-foot syndrome induced by fluoropyrimidines: A systematic review and meta-analysis

The aims of this study were to evaluate the efficacy of herbal medicine for the prevention and management of hand-foot syndrome (HFS) induced by fluoropyrimidines and to identify herbs associated with HFS alleviation for further research. The PubMed, Cochrane, Springer, China National Knowledge Infrastructure, and Wanfang databases were searched up to May 2017 for randomized controlled trials (RCTs) that evaluated herbal medicine for relieving HFS in patients undergoing fluoropyrimidine-based chemotherapy. Study evaluation and synthesis methods were in accordance with the Cochrane Handbook, and data were analyzed using RevMan 5.3. In total, 35 RCTs (2,668 participants) were included. Meta-analysis showed that the addition of herbal medicine significantly reduced the incidences of all-grade and high-grade HFS. The total effective rate and complete remission rate of HFS patients increased significantly with herbal medicine arm. Further sensitivity analysis identified Paeoniae Radix Alba, Carthami Flos, Cinnamomi Ramulus, and Glycyrrhizae Radix et Rhizoma as being consistently associated with significant reductions in HFS incidence without important heterogeneity. However, the lack of blinding in most studies may have led to overestimation of these effects. More high-quality RCTs and experimental research are needed to confirm and investigate the efficacy of the herbs identified in this study.
