Correlation between docetaxel-induced skin toxicity and the use of steroids and H₂ blockers: a multi-institution survey

H2 antihistamines: May be useful for combination therapies in cancer?

Cancer morbimortality is still a great concern despite advances in research and therapies. Histamine and its receptors' ligands can modulate different biological responses according to the cell type and the receptor subtype involved. Besides the wide variety of histamine functions in normal tissues, diverse roles in the acquisition of hallmarks of cancer such as sustained proliferative signaling, resistance to cell death, angiogenesis, metastasis, altered immunity and modified microenvironment have been described. This review summarizes the present knowledge of the various roles of histamine H2 receptor (H2R) ligands in neoplasias. A bioinformatic analysis of human tumors showed dissimilar results in the expression of the H2R gene according to tumor type when comparing malignant versus normal tissues. As well, the relationship between patients' survival parameters and H2R gene expression levels also varied, signaling important divergences in the role of H2R in neoplastic progression in different cancer types. Revised experimental evidence showed multiple effects of H2R antihistamines on several of the cited hallmarks of cancer. Interventional and retrospective clinical studies evaluated different H2R antihistamines in cancer patients with two main adjuvant uses: improving antitumor efficacy (which includes regulation of immune response) and preventing toxic adverse effects produced by chemo or radiotherapy. While there is a long path to go, research on H2R antihistamines may provide new opportunities for developing more refined combination therapeutic strategies for certain cancer types to improve patients' survival and health-related quality of life.

Paclitaxel-induced periarticular thenar eminence erythema with onycholysis: A case report

Paclitaxel is a drug frequently used in the treatment of gynecological cancers. Its cutaneous side effects are fairly well documented. A subtype of hand-foot syndrome, periarticular erythema of the thenar eminences with onycholysis, is rarer. Here, we present a case of a woman treated with paclitaxel for recurrent ovarian cancer who developed periarticular thenar eminence erythema with onycholysis syndrome. Involvement presented as an erythematous rash on the top of the left hand progressing up the arm. A lesion was also present on the right lower limb and on the dorsal surface of the right foot with onycholysis. Edema was present in the fingers, hands, forearms, and feet. A punch biopsy and pathological analysis confirmed the diagnosis of periarticular thenar eminence erythema with onycholysis syndrome. Rapid identification and treatment with topical corticosteroids limited irreversible damage.

A randomized clinical trial comparing physician-directed or fixed-dose steroid replacement strategies for incomplete dexamethasone dosing prior to docetaxel chemotherapy

PURPOSE

Prior to docetaxel chemotherapy, incomplete dosing of steroid premedication is common. The lack of standardized steroid replacement strategies can lead to variability in care and delays in starting docetaxel.

METHODS

This randomized trial compared physician-directed with fixed-dose dexamethasone. Patients who had missed at least one dose of steroid premedication were randomized to physician-directed replacement (any choice of steroid, dose or route) or to dexamethasone 8 mg oral before starting docetaxel. The primary outcome was time from randomization to starting docetaxel. Secondary outcomes included rates of acute and delayed hypersensitivity reactions, fluid retention and skin toxicity.

RESULTS

Of 60 eligible patients, 30 (50%) and 30 (50%) were randomized to physician-directed and fixed-dose arms, respectively. Overall tumour types: breast (42 [70%]), gastrointestinal (7 [12%]), prostate (7 [12%]) and lung (3 [7%]). Dexamethasone was most commonly incompletely taken with cycles 1 (28 [48%]) and 2 (13 [22%]) of docetaxel. Seven different replacement strategies were used in the physician-choice arm. Patients in the fixed-dose arm received docetaxel a mean of 21.2 (95% CI for the difference is 2.1 to 44.6) minutes earlier than the physician-choice arm (p = 0.033 Wilcoxon rank sum test or p = 0.073 two-sample t test). Median time to docetaxel was 47.5 vs 61 min (mean 62.2 vs 83.4 min) by arm, respectively. No significant difference in toxicity rates was observed.

CONCLUSION

While not meeting our predefined criteria of improving the time from randomization to starting docetaxel by 30 min, the fixed-dose replacement strategy reduced both the time to starting docetaxel and treatment variability. Fixed dosing with oral dexamethasone 8 mg should be the preferred standard of care. REGISTRATION: www.clinicaltrials.gov NCT02815319 REGISTRATION DATE: June 28, 2016.

Current status of eye disorders caused by docetaxel administration every 3 weeks: A case-control study in Japanese patients

PURPOSE

Docetaxel is known to cause eye disorders. In this study, current status of eye disorders caused by docetaxel administration every 3 weeks in Japanese patients was examined.

METHODS

This case-control study targeted patients who were newly administered docetaxel at the Kyoto Okamoto Memorial Hospital between 1 July 2015 and 30 June 2018. Eye disorder occurrence was defined as an event in which the pharmacist confirmed the symptoms in a patient interview and the ophthalmologist diagnosed the disorder.

RESULTS

Of the 89 subjects, 7 (7.9%) had eye disorders. The symptoms were watering eyes (7.9%), a stye and eye discharge (2.2% each), corneal and conjunctival disorder, visual acuity reduction, and blepharedema (1.1% each). Four patients who presented with watering eyes, eye discharge, or corneal and conjunctival disorder showed improvement with the use of eye drops such as artificial tears. Two patients who presented with a stye showed improvement with the use of oral cefcapene. One patient with mild symptoms showed spontaneous improvement. However, one patient had irreversible visual acuity reduction. The multivariate logistic regression analysis revealed that a cumulative docetaxel dose of ≥300 mg/m² (odds ratio: 15.50, 95% confidence interval: 1.37-175.00, p = 0.027) and concomitant cyclophosphamide use (odds ratio: 13.20, 95% confidence interval: 1.13-153.00, p = 0.039) were significant risk factors associated with eye disorders.

CONCLUSION

In conclusion, it was determined that docetaxel-related eye disorders might be influenced by the cumulative dose of docetaxel and concomitant cyclophosphamide use. In addition, relatively mild symptoms improved with medication.

Dermatological adverse events with taxane chemotherapy

Taxanes (docetaxel and paclitaxel) are among the most commonly prescribed anticancer drugs approved for the treatment of metastatic or locally advanced breast, non-small cell lung, prostate, gastric, head and neck, and ovarian cancers, as well as in the adjuvant setting for operable node-positive breast cancers. Although the true incidence of dermatological adverse events (AEs) in patients receiving taxanes is not known, and has never been prospectively analysed, they clearly represent one of the major AEs associated with these agents. With an increase in the occurrence of cutaneous AEs during treatment with novel targeted and immunological therapies when used in combination with taxanes, a thorough understanding of reactions attributable to this class is imperative. Moreover, identification and management of dermatological AEs is critical for maintaining the quality of life in cancer patients and for minimizing dose modifications of their antineoplastic regimen. This analysis represents a systematic review of the dermatological conditions reported with the use of these drugs, complemented by experience at comprehensive cancer centres. The conditions reported herein include skin, hair, and nail toxicities. Lastly, we describe the dermatological data available for the new, recently FDA-and EMA- approved, solvent-free nab-paclitaxel.

Multikinase Inhibitor-Induced Hand-Foot Skin Reaction: A Review of Clinical Presentation, Pathogenesis, and Management

Multikinase inhibitors (MKIs) are targeted cancer therapies designed to inhibit multiple tyrosine kinase pathways responsible for tumor proliferation, growth, and survival. These agents are more able to target cancer cells and possess better safety profiles than conventional chemotherapies. However, MKIs can produce significant cutaneous adverse events, hand-foot skin reaction (HFSR) being the most clinically significant. Although not life threatening, HFSR can lead to MKI dose modification, interruption, or termination, potentially limiting the anti-tumor effect. This article summarizes the current knowledge concerning the epidemiology, clinical presentation, pathogenesis, histopathology, prognostic implication, and current evidence-based prophylactic and reactive treatment options for MKI-induced HFSR. Its high incidence and significant impact on the quality of life emphasizes the great need to understand the pathogenesis and improve management of this condition.

Optimisation of steroid prophylaxis schedules in breast cancer patients receiving docetaxel chemotherapy-a survey of health care providers and patients

PURPOSE

Despite the widespread use of steroid prophylaxis schedules for breast cancer patients receiving docetaxel chemotherapy, questions still exist regarding their optimal use. We surveyed health care providers and patients about their experiences with steroid prophylaxis.

METHODS

Two questionnaires were developed and circulated. One was presented to health care providers (chemotherapy nurses, pharmacists and medical oncologists) involved in the treatment of breast cancer and the second to patients who had received docetaxel chemotherapy for early stage breast cancer.

RESULTS

The health care providers' questionnaire was completed by 184 of 698 invitees: 92/171 (53.8 %) chemotherapy nurses, 56/284 (19.7 %) pharmacists and 36/243 (14.8 %) medical oncologists (overall response rate 26.4 %). Two steroid schedules were found to be the most commonly used: dexamethasone 8 mg BID for 6 doses, with either 3 (79 %) or 2 (11 %) doses taken before docetaxel administration. Suboptimal adherence to steroid premedication had been experienced by 98 % (177/181) of practitioners. Despite the presence of local treatment protocols in 65 % (119/183) of practitioners' institutions, 10 different strategies were commonly used when steroid premedication was taken incorrectly. The patients' questionnaire was completed by 72/87 (82.3 %) invitees. Respondents reported correctly taking their premedication 99 % (70/71) of the time. Patients felt steroids frequently caused side effects, the most common being sleep disturbance (35/72 = 49 %) and skin toxicity (16/72 = 22 %).

CONCLUSION

Suboptimal adherence to steroid premedication prior to docetaxel administration is a common clinical challenge. There appears to be discordance between the practitioner and the patient experience. A single, universally accepted and used protocol for both pre- and post-medication and management when premedication is not taken as prescribed could improve adherence.

Prevention strategies for chemotherapy-induced hand-foot syndrome: a systematic review and meta-analysis of prospective randomised trials

PURPOSE

Hand-foot syndrome (HSF) is a distinctive adverse event relatively frequent to some chemotherapeutic agents as capecitabine, pegylated liposomal doxorubicin, sorafenib and other tyrosine-kinase inhibitors. Since the prevention of HFS would be crucial to avoid treatment interruptions and delays, many studies have been conducted with this purpose.

METHODS

The aim of this systematic review and meta-analysis was to analyze the clinical efficacy of prevention strategies for HFS, through a wide search of electronic databases as well as congress abstracts. The endpoints evaluated were the dichotomic data for mild (Grade 1), moderate to severe (Grades 2 to 3) and all-grade HFS. Meta-analysis was calculated through RevMan v5.1 software.

RESULTS

Amongst 295 studies identified, only ten met the inclusion criteria. Celecoxib prevented both moderate to severe (odds ratio [OR] 0.39, 95 % confidence interval [CI] 0.20-0.73, P = 0.003) and all-grade HFS (OR 0.47, 95 % CI 0.29-0.78, P = 0.003), whereas pyridoxine and topical urea/lactic acid formulations failed to prove efficacy. There were no proven benefits in mild HFS. The use of topical antiperspirant has not been shown to improve results, according to a single trial.

CONCLUSIONS

From all available possibilities for the prevention of HFS, celecoxib appears to be the most promising, with statistically significant results. Larger, multicentric studies are required to reinforce this finding.

Feasibility of 4 cycles of docetaxel and cyclophosphamide every 14 days as an adjuvant regimen for breast cancer: a Wisconsin Oncology Network study

INTRODUCTION

Dose-dense therapies have had a major effect on reducing toxicity and improving outcomes in breast cancer. A combination of TC every 3 weeks has emerged as a common chemotherapy regimen used for treatment of node-negative or lower-risk node-positive breast cancer. We tested whether it is feasible to deliver TC on a dose-dense schedule, with therapy completed within 10 weeks.

PATIENTS AND METHODS

We enrolled women with early stage breast cancer on a single-arm phase II study of adjuvant dose-dense TC through a regional oncology network. All women completed primary surgery before accrual, and subsequent therapy with TC was deemed appropriate by the treating physician. Planned treatment was docetaxel 75 mg/m(2) plus cyclophosphamide 600 mg/m(2) every 2 weeks for 4 cycles with subcutaneous pegfilgrastim 6 mg administered 24 to 48 hours after the administration of each chemotherapy cycle.

RESULTS

Of 42 women enrolled, 41 were evaluable using prespecified criteria. Of these, 37 (90.2%) completed therapy within 10 weeks and 34 (83%) completed therapy at 8 weeks without dose modification. Rates of neuropathy were similar to that reported previously. The rate of neutropenic fever was low (2.5%). Rash and plantar-palmar erythrodythesia were common and reached grade 3 in 4 subjects (9.8%).

CONCLUSION

Dose-dense TC is feasible with tolerability profiles similar to standard TC and a low likelihood of neutropenic fever. This study supports further clinical development of this 8-week adjuvant chemotherapy regimen.

Docetaxel-induced skin toxicities in breast cancer patients subsequent to paclitaxel shortage: a case series and literature review

PURPOSE

As the result of a recent national shortage in paclitaxel, some patients who were receiving or scheduled to receive weekly paclitaxel were converted to every 3-week (q3w) docetaxel with granulocyte colony-stimulating factor support. Our institution noted higher than expected incidence of severe skin toxicity events attributable to docetaxel during the shortage period among our breast cancer patients. In this report, we summarize the clinical course of the first five cases, review the literature surrounding docetaxel-induced skin toxicity, and offer possible prevention and treatment strategies to improve docetaxel tolerability.

METHODS

The observation period for this case series was August 1 through October 21, 2011. All patients treated with docetaxel were identified from our electronic medical record. Operable stage I-III breast cancer patients who received ≥ 1 dose of docetaxel monotherapy at 75-100 mg/m(2) q3w were included in this study. The cases of grade 3-4 docetaxel-induced skin toxicities identified by the treating oncologists were then contacted and signed an informed consent through an Institutional Review Board-approved protocol.

RESULTS

Thirty-four patients met the inclusion criteria. Five patients (14.7 %) experienced grade 3 skin toxicity events attributable to docetaxel, a significantly higher rate than previously reported for docetaxel dosed at 75-100 mg/m(2).

CONCLUSIONS

Docetaxel-induced dermatologic toxicity is well characterized; nonetheless, its etiology is largely unknown and evidence-based prevention and management strategies are lacking. This report shows that the use of docetaxel 75-100 mg/m(2) q3w subsequent to dose-dense doxorubicin and cyclophosphamide regimen can lead to unacceptable rate of severe skin toxicity.

An overview of the Japan Breast Cancer Research Group (JBCRG) activities

The purpose of this article is to describe the current status and future perspectives of the Japan Breast Cancer Research Group (JBCRG). The JBCRG was organized in 2002, with the following purpose: to plan and promote clinical trials and basic research in breast cancer domestically and multilaterally; to conduct research and surveys on domestic and foreign information on medical care for breast cancer and to diffuse and highlight such information; to improve and promote clinical technologies for breast cancer; to act as an intermediary to liaise and strengthen alliances with affiliated organizations; and, to contribute to the public welfare by improving outcomes in breast cancer. The clinical trials are led by doctors/investigators in the JBCRG. And the purpose is to establish standard treatment for patients and provide substantial evidence. The JBCRG implements international collaboration in some researches/studies. As of January 2012, fourteen trials have been closed and nine are open to recruitment.

Docetaxel-induced hand foot syndrome: "No dose is a safe dose"

Docetaxel is an important chemotherapeutic agent used in the management of many solid tumors. The most important side effect of this drug is myelosupression. We report a case of carcinoma breast that developed severe hand-foot syndrome at 75 mg/m² doses of docetaxel. The exact mechanism of this side effect in not known. All the physicians using this drug must be aware of this side effect.
