The impact of comorbidities, neutrophil-to-lymphocyte ratio, and drug toxicities on quality of life in lung cancer patients receiving EGFR-TKI therapy

BACKGROUND

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are used as the standard first-line treatment for patients with advanced EGFR-mutated non-small cell lung cancer (NSCLC). However, the impact of comorbidities and treatment toxicities on quality of life (QoL) was seldom investigated.

OBJECTIVE

We aimed to investigate the association of comorbidities, adverse events (AEs), and QoL in treatment-naïve advanced NSCLC patients receiving EGFR-TKI treatments.

METHODS

This multi-center prospective observational study was conducted to evaluate QoL and AEs at baseline, the 2nd, 4th, 12th, and 24th week. Clinical characteristics, comorbidities, and pre-treatment laboratory data were recorded. QoL was assessed by using the summary score of the EORTC QLQ-C30 and the dermatology life quality index. The impact of comorbidities, neutrophil-to-lymphocyte ratio (NLR), and AEs on QoL was analyzed by generalized estimating equations.

RESULTS

A total of 121 patients were enrolled. Diarrhea (p = 0.033), anorexia (p < 0.001), and NLR ≥4 (p = 0.017) were significantly associated with a QoL impairment. Among skin toxicities, acneiform rash (p = 0.002), pruritus (p = 0.002), visual analogue scale for pruritus (≥3 and < 7, p = 0.006; ≥7, p = 0.001) and pain (1-3, p = 0.041) were associated with a QoL impairment. No significant association was found between comorbidities and QoL changes.

CONCLUSION

Diarrhea, anorexia, skin pain, and pruritus may cause a deterioration in QoL in patients receiving EGFR-TKI therapy. NLR may be a potential predictive factor for QoL impairment. Aggressive management and close monitoring for these clinical factors are crucial to improve QoL.

Combination of available topical beta-blockers and antibiotic ointment for epidermal growth factor receptor tyrosine kinase inhibitor-induced paronychia and pseudopyogenic granulomas in Taiwan

BACKGROUND

Painful paronychia and pseudopyogenic granuloma (PG) are common adverse drug reactions (ADRs) associated with the use of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) to treat non-small cell lung cancer (NSCLC). Multiple local management approaches have been tested with unsatisfactory results. We have introduced an occlusion therapy technique through which available topical drugs for longer than 2 years.

METHODS

Based on the cancer registry and case management system of our hospital, from July 2019 to July 2020, we retrospectively enrolled patients with NSCLC who were treated with EGFR-TKIs and received applications of 0.5% timolol ophthalmic solution (TIMOPTOL XE 0.5%®) combined with a neomycin/tyrothricin ointment (Biomycin®) using the occlusion method to treat paronychia or PG.

RESULTS

A total of 22 patients were enrolled, with a mean age of 66.5 years, most of whom were women (72.7%). Periungual lesion-related pain was reported by all patients, and periungual bleeding and PG were reported in 14% (3/22) and 64% (14/22) of patients, respectively. After the occlusion therapy application of timolol ophthalmic solution combined with neomycin/tyrothricin ointment twice daily, the overall response rate was 83.3%, including complete response in 18% (4/22) of cases and partial response in 68% (15/22) of cases.

CONCLUSION

We presented an occlusion method using available topical beta-blockers and antibiotic ointment for EGFR-TKI-induced paronychia and PG in Taiwan. The result is favorable. Further randomized control trial is urgent to validate our findings.

Association between dermatologic adverse events and quality of life in lung cancer patients treated with epidermal growth factor receptor-tyrosine kinase inhibitors

PURPOSE

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are frequently associated with dermatologic adverse events (dAEs), having great impacts on patients' health-related quality of life (HRQoL) and treatment adherence. We aimed to examine the association between various dAEs and HRQoL in patients treated with EGFR-TKI therapy.

METHODS

This was a cross-sectional study including 132 non-small-cell lung cancer (NSCLC) patients treated with gefitinib, erlotinib, afatinib, or osimertinib in Taiwan. The severity level of dAEs was graded by NCI-CTCAE v4.03 and PRO-CTCAE ITEMS v1.0. All participants answered the Functional Assessment of Cancer Therapy-Epidermal Growth Factor Receptor Inhibitors (FACT-EGFRI-18) HRQoL questionnaire.

RESULTS

The clinician-reported severity of pruritus, photosensitivity, alopecia, and Karnofsky performance status was associated with HRQoL (β =  - 6.773, p = 0.046; β =  - 5.250, p = 0.032; β =  - 8.121, p = 0.001; β = 0.327, p = 0.002; respectively). The clinician-reported severity of all dAEs except paronychia had negative correlations with HRQoL. The symptom gradings of CTCAE and PRO-CTCAE had positive correlation.

CONCLUSIONS

The severity of pruritus, photosensitivity, and alopecia was associated with HRQoL of patients receiving EGFR-TKI therapy. Using patient-reported outcome measurements helps clinicians to capture the actual impact of symptoms on physical, social-emotional, and functional well-being.

Red light emitting diode as an adjuvant treatment for epidermal growth factor receptor inhibitors-induced paronychia

We evaluated the efficacy and safety of red light LED as an adjuvant treatment for epidermal growth factor receptor inhibitor-induced paronychia. Eight patients were recruited in this randomized, single-blinded controlled trial. They were randomized to receive red-light on one hand or foot 2-3 times/week for 6 weeks while the contralateral side served as controls. The standard treatments were continued. Erythema and lesion elevation observed by Anthera^® 3D, severity and pain scores were obtained at weeks 0, 2, 4, 6, and 8. The red light group showed significantly lower erythema, severity, and pain scores at weeks 4, 6, and 8. The elevation was significantly lower in the red light group at every follow-up visit. No adverse events occurred. Red light therapy may be an option as adjunctive treatment for EGFRi-induced paronychia.

Efficacy of topical beta-blockers in the management of EGFR-inhibitor induced paronychia and pyogenic granuloma-like lesions: case series and review of the literature

Nail toxicities, such as paronychia and pyogenic granuloma-like lesions, are well-recognized side effects of epidermal growth factor receptor inhibitor (EGFR-I) therapy that can significantly impair patient’s quality of life and compliance to anticancer treatment. Numerous therapeutic options are available, with variable rates of success. Recently, topical β-blockers have emerged as a novel, non-invasive treatment strategy. We tested the effectiveness of topical timolol 0.5% gel, twice daily, under occlusion for 30 days, on paronychia and periungual pyogenic granuloma-like lesions in 9 patients being treated with EGFR-I. We also reviewed the available literature on this topic, which is the use of topical β-blockers in the management of EGFR-I-induced nail toxicities. We assessed 25 lesions consistent with the diagnosis of EGFR-I-induced pyogenic granuloma-like lesions and paronychia (21 diagnosed as pyogenic granuloma-like, and four as paronychia). Thirteen of the 25 lesions achieved complete resolution, 9/25 reached at least improvement, and only 3/25 did not respond to the intervention. As for the review, four papers met the scope of our research. The results confirmed at least partial benefit in the majority of treated patients. Among current strategies, high-potency topical corticosteroids are a well-known treatment option especially for paronychia, targeting the inflammatory component of such lesions; nevertheless, the management of pyogenic granuloma-like lesion is often more complex and the success rate is variable. Nail plate avulsion and phenol chemical matricectomy are not highly effective and display some degree of invasiveness. Topical β-blockers seem to be promising alternatives, especially in fragile cancer patients who may be unsuitable candidates for an invasive procedure.

A randomized phase 2 trial of the efficacy and safety of a novel topical povidone-iodine formulation for Cancer therapy-associated Paronychia

Purpose Cancer therapy-associated paronychia (CAP) is a frequent adverse event associated with cytotoxic and targeted therapies that may impact dosing of anticancer therapies and patient quality of life (QoL). There are currently no evidence-based management strategies or approved treatments for CAP. Materials and Methods This was a prospective, multicenter, randomized, double-blind, vehicle-controlled phase 2 study that evaluated the efficacy and safety of 6 to 8 weeks of 1% or 2% povidone-iodine (PVP-I) topical solution versus vehicle-control in adult patients with CAP. Patients were randomized to one of three treatment arms administered twice daily: 1% PVP-I (Cohort A), 2% PVP-I (Cohort B), or vehicle-control (Cohort C). The primary endpoint was a two-grade reduction (or reduction to grade 0 if involved nails were grade 1) on the six-point Paronychia Severity Grading (PSG) scale. Secondary endpoints included safety and the effect on QoL and microbiota. Results A total of 102 patients with cancer were randomized to the study. In Cohort A, 83 of 205 (40.5%, P = 0.6059) affected nails met the primary endpoint versus Cohort C. In Cohort B, 88 of 167 (52.7%, P = 0.0063) affected nails met the primary endpoint versus 64 of 169 (37.9%) in Cohort C. Nineteen of 29 patients (65.5%) in Cohort B reported moderately or very painful nails at baseline that decreased to 15 patients (51.7%) at visit 2 and five patients (17.2%) at visit 3. Conclusions Treatment with twice-daily topical 2% PVP-I was safe and resulted in improvement in CAP compared with control.
