Topical corticosteroid therapy for facial acneiform eruption due to EGFR inhibitors in metastatic colorectal cancer patients: a randomized controlled trial comparing starting with a very strong or a weak topical corticosteroid (FAEISS study, NCCH1512, colorectal part)

Management of human epidermal growth factor receptor inhibitors-related acneiform rash: A position paper based on the first Europe/USA Delphi consensus process

BACKGROUND

There is a need for unified guidance in the management of acneiform rash induced by epidermal growth factor receptor inhibitors (EGFRi) among dermatologists.

OBJECTIVE

To establish unified international guidelines for the management of acneiform rash caused by EGFR inhibitors, based on an experts' Delphi consensus.

METHODS

The initiative was led by five members of the European Academy of Dermatology and Venereology Task Force 'Dermatology for Cancer Patients' who developed a questionnaire that was circulated to a group of 32 supportive oncodermatology experts in Europe, Canada, Argentina, the US States and Asia. The questionnaire consisted of 84 statements in total, regarding diagnosis and treatment of EGFRi-induced acneiform rash. Experts responded to an anonymous 5-point Likert scale survey. The coordinators collected the first-round responses that were checked for consensus (≥75% agreement in positive [agree or strongly agree] or in negative [disagree or strongly disagree] vote). The statements that did not reach strong consensus in the first round were revised, according to experts' feedback, for a second-round survey.

RESULTS

Strong consensus was reached in 75/84 (89.3%) of the statements, whilst moderate consensus was achieved in 6/84 elements. Key points include consideration of low-dose isotretinoin for refractory grade II/III acneiform rash, use of topical steroid-sparing agents like topical pimecrolimus in the maintenance phase and use of doxycycline in either 100 or 200 mg per day as prophylactic treatment. Interestingly, experts did not recommend topical antibiotics, neither for prevention, nor for treatment. Consensus failure in 3/84 objects is mostly related to the lack of robust data on these topics.

CONCLUSION

This consensus offers crucial insights often overlooked by radiotherapists, general practitioners, dermatologists and oncologists, and it is expected to improve the management of oncologic patients treated with EGFRi in different settings and continents.

Skin Toxicity as a Predictor of Survival in Metastatic Colorectal Cancer Patients Treated with Anti-EGFR: Fact or Fallacy?

The primary treatment for metastatic colorectal cancer (mCRC) consists of targeted therapy and chemotherapy to improve survival. A molecular target drug with an anti-epidermal growth factor receptor (EGFR) antagonist is recommended when the RAS and BRAF genes are normal. About 50–70% of patients using anti-EGFR antagonists will experience skin reactions. Some studies have shown that severe skin reactions caused by anti-EGFR antagonists may be linked to overall survival (OS) and progression-free survival (PFS), but the results are still uncertain. These data of mCRC patients who underwent anti-EGFR therapy between October 2017 and October 2018 were analyzed retrospectively. A total of 111 patients were included in this study. The survival results showed that gender, age, body mass index, primary tumor site, and recurrence did not significantly affect OS and PFS. However, the first-line anti-EGFR inhibitor treatment was significantly associated with OS (p < 0.001) and PFS (p < 0.001). There was no significant difference in the incidence of acne between males and females in grades 1 and 2, while males have a greater risk in grades 3 and 4 than females (20.3 vs. 4.8%; p-value = 0.041). Skin toxicity was not a predictor of anti-EGFR treatment response in this investigation.

Corticosteroids in oncology: use, overuse, indications, contraindications. An Italian Association of Medical Oncology (AIOM)/ Italian Association of Medical Diabetologists (AMD)/ Italian Society of Endocrinology (SIE)/ Italian Society of Pharmacology (SIF) multidisciplinary consensus position paper

Corticosteroids (CSs) are widely used in oncology, presenting several different indications. They are useful for induction of apoptosis in hematological neoplasms, for management of anaphylaxis and cytokine release/hypersensitivity reaction and for the symptomatic treatment of many tumour- and treatment-related complications. If the employment of CSs in the oncological setting results in several benefits for patients and satisfaction for clinicians, on the other hand, many potential adverse events (AEs), both during treatment and after withdrawal of CSs, as well as the duality of the effects of these compounds in oncology, recommend being cautious in clinical practice. To date, several gray zones remain about indications, contraindications, dose, and duration of treatment. In this article, a panel of experts provides a critical review on CSs therapy in oncology, focusing on mechanisms of action and pharmacological characteristics, current and emerging therapeutic indications/contraindications, AEs related to CSs treatment, and the impact on patient outcome.
