Diclofenac sodium gel therapy as an alternative to actinic cheilitis

Clinicopathological Analysis of Actinic Cheilitis: A Systematic Review with Meta-analyses

BACKGROUND

This systematic review aimed to conduct a complete investigation of the demographic aspects, clinicopathological features, degrees of epithelial dysplasia, and malignant transformation rate of actinic cheilitis.

METHODS

The study was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered in the International Prospective Register of Systematic Reviews (CRD42020201254). A search without year and language restrictions was performed using PubMed/MEDLINE, Embase, Virtual Health Library, Scopus, Web of Science, and gray literature. Studies that provided information on patients with actinic cheilitis were included, excluding those with general information on other diseases or other types of cheilitis. Risk of bias was explored using the Joanna Briggs Institute tool. Narrative and quantitative data syntheses were performed using meta-analyses and subgroup analyses. Association tests were also performed.

RESULTS

Thirteen studies (728 patients) were included. The most prevalent clinical signs were dryness (99%), blurred demarcation between the lip vermilion and skin (82%), scaling (69%), and atrophy (69%). Regarding epithelial dysplasia, a prevalence of mild dysplasia (34.2%), followed by moderate (27.5%), and severe (14.9%). The malignant transformation rate was 14%. Crusts, ulcerations, and erythematous areas were associated with lip carcinoma (p < 0.001), and scaling was associated with actinic cheilitis (p < 0.001).

CONCLUSIONS

This study revealed several features of actinic cheilitis, providing an overview of the disease. It is suggested that new studies help develop policy guides for the standardization of clinical criteria, enabling more rigorous and homogeneous analysis of actinic cheilitis.

Treatment Options and Post-Treatment Malignant Transformation Rate of Actinic Cheilitis: A Systematic Review

Simple Summary

Actinic cheilitis is a precancerous condition that may evolve to a more aggressive type of skin cancer. Therefore, its therapy is crucial for the disease prognosis. In this systematic review, we tried to identify the best therapies of actinic cheilitis regarding safety, efficacy, recurrences, and the potential to progress to skin cancer. The therapeutic approach comprised invasive and topical treatments. The invasive therapies, such as partial surgery and laser treatments, had the best cosmetic and therapeutic results with few recurrences. Photodynamic therapy demonstrated satisfactory outcomes, while topical treatments were the least beneficial. Notably, the efficacy of photodynamic therapy was improved when combined with 5% imiquimod. However, except from photodynamic therapy, the other modalities were assessed in a limited number of patients. Finally, when actinic cheilitis is treated, no risk of cancer progression exists. Larger studies are necessary to confirm these results.

Abstract

Actinic cheilitis is a premalignant condition that may evolve to squamous cell carcinoma. A consensus on its management has not been established, and large clinical trials are lacking. We aimed to review the existing data regarding the treatment of actinic cheilitis with various modalities regarding safety, efficacy, recursions, and post-treatment malignant transformation. A systematic review was conducted through Pubmed, Ovid and the Cochrane library for studies in English language and the references of included papers from inception to January 2021. Case series were considered if ≥6 patients were included. Of the 698 articles, 36 studies and, overall, 699 patients were eventually reviewed. Laser ablation and vermilionectomy provided the best clinical and aesthetic outcomes with few recurrences, while photodynamic therapy was linked to more relapses. Generally, the adverse events were minor and there was no risk of post-treatment malignant transformation. The limitations of our review include the heterogeneity and the small number of patients across studies. Conclusively, invasive treatments demonstrated superior therapeutic and safety profile. Nevertheless, high-quality head-to-head studies that assess different modalities for actinic cheilitis and report patient preferences are lacking.

Use of topical anti-inflammatory and antineoplastic agents in the treatment of young-aged actinic cheilitis: A systematic review

INTRODUCTION

Several treatments have been used to reduce inflammation and to reverse epithelial alterations in actinic cheilitis (AC).

AIM

A systematic review was conducted to analyze the potential of topical treatments for remission and clinical improvement of AC as well as patient acceptability.

METHODS

A systematic review of clinical trials was conducted following the PICO strategy to answer the following question: Are topical anti-inflammatory and antineoplastic agents effective in the treatment of actinic cheilitis? The quality of the studies was assessed by ROB-2, and the certainty of evidence was rated by GRADE guidelines.

RESULTS

Eight clinical trials were selected, including four that investigated the use of anti-inflammatory drugs and four use of antineoplastic agents. The use of 3% diclofenac sodium was associated with partial remission of AC, while 5% imiquimod and ingenol mebutate promoted complete remission. Furthermore, 5% fluorouracil was the drug most associated with complications during treatment. Diclofenac sodium (3%) and fludroxycortide showed the best acceptance by the patients, especially in terms of symptom relief and comfort provided.

CONCLUSION

The anti-inflammatory and antineoplastic agents analyzed largely provided good clinical outcomes, with evidence of remission of AC lesions, development of few local adverse reactions during treatment, and good patient adherence.

Fludroxycortide cream as an alternative therapy for actinic cheilitis

OBJECTIVES

The objective of the study is to assess, by clinical follow-up, the efficacy of the dermatological cream Fludroxycortide 0.125 mg/g (Drenison®) in the treatment of actinic cheilitis (AC).

MATERIAL AND METHODS

Twenty-three patients diagnosed with AC participated in the study. Fifteen were submitted to corticotherapy with Fludroxycortide, applied three times a day for up to 6 weeks, associated with lip sunscreen (LS) before sun exposure. In the control group of eight patients, only the use of LS was established. At each weekly return, a photographic record was made of the lesion. After treatment, images were evaluated and scores were assigned to verify clinical evolution. Also, patients treated with Fludroxycortide responded to a questionnaire, to assess drug tolerability and treatment satisfaction.

RESULTS

In the group treated with Fludroxycortide (n = 15), five patients showed total improvement, seven presented partial improvement, and three showed no clinical change. Concerning the patients treated with LS (n = 8), one presented total remission of the clinical lesion characteristics, four exhibited partial improvement, and three exhibited no clinical lip alteration. No case presented symptom worsening. Of the 15 patients undergoing corticotherapy, 12 were satisfied and reported that the product was not irritating and contributed to lesion improvement.

CONCLUSIONS

Conventional treatment with LS was effective in the remission of some AC lesions, but treatment responses were improved when associated with Fludroxycortide, especially in the more severe cases.

CLINICAL RELEVANCE

As it is a non-invasive therapy leading, in most cases, to adequate clinical results, safety, and tolerability, Fludroxycortide can be considered an effective alternative treatment for AC.

Clinical and histopathological study of actinic cheilitis

Abstract Introduction Actinic cheilitis is a inflammatory condition affecting mainly the lower lip and it is caused by chronic and excessive exposure of the lips to the ultraviolet radiation in sunlight. Objective Identifying clinical and histopathologic characteristics in 40 cases histopathologically diagnosed as actinic cheilitis. In addition, to investigate possible associations between these aspects. Method Defined as an observational, transversal, retrospective and descriptive study, it registered data regarding age, gender, occupation, symptomatology, records of sun exposure, frequency of sunblock use, tabagism, skin color, clinical aspect and histopathological classification. The data was submitted to the chi square test of Pearson (p<0.05). Result There was a predominance of male gender, leucodermia, and ages ranging between 50 and 60 years. The most common occupation was farming. From our sample, 85% had history of chronic sun exposure, in which 50% reported the use of some type of sunblock and only 25% were smokers. The main clinical condition was non-ulcerated leukoplakia and in the histopathological study, the hyperkeratosis were more common. A correlation between the degree of tissue alteration verified in the histopathological diagnosis and the studied clinical variables was not established (p=0.112). Conclusion The clinical aspect of the wound can conceal tissue alterations in different stages, emphasizing the importance of a premature diagnosis.
