Santana T, Matuck B, Tenório JR, Braga MM. Can immunohistochemical biomarkers distinguish epithelial dysplasia degrees in actinic cheilitis? A systematic review and meta-analysis. Med Oral Patol Oral Cir Bucal 2020; 25:e106-e116. [PMID: 31880283 PMCID: PMC6982981 DOI: 10.4317/medoral.23223] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Accepted: 09/16/2019] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Actinic cheilitis (AC) is a potentially malignant disorder of the lip, characterized by epithelial and connective tissue alterations caused by chronic exposure to ultraviolet radiation. In the past decades, diverse studies have been conducted in lip carcinogenesis and many biomarkers have been identified in lip lesions, yet there is no scientific evidence that determines its usefulness in the clinical setting or in histopathological routine. Therefore, we conducted the first systematic review in this field to summarize the results of published studies on immunohistochemical biomarkers in lip carcinogenesis, to evaluate if there is a marker than can distinguish the different histological grades of AC. MATERIAL AND METHODS Retrospective studies that investigated immunohistochemical biomarkers in AC defined on standardised histological assessment were gathered from five databases and evaluated. Each study was qualitatively evaluated using the Critical Appraisal Tools from SUMARI. RESULTS The proliferation marker Ki-67 was the most studied biomarker and we observed, through meta-analysis, that it was differently expressed between AC and lip cancer, but not in AC subgroups. Most articles had a high risk of bias. CONCLUSIONS In summary, the literature lacks quality follow up studies in actinic cheilitis. Multi-centre cohort studies, with patients stratified by treatment type and the use of image analysis software, could be the solution to further address the issues of investigating potentially malignant lesions and help change clinical practice, in terms of individualizing patients' treatment and prognosis prediction.

Abstract
Abstract The objective of the present study was to determine the prevalence of actinic cheilitis among extractive mining workers and factors associated with the condition, especially the relationship between clinical appearance and the length of occupational exposure to sunlight. A cross-sectional study was performed in Dona Inês, Paraíba, Brazil between 2014 and 2015. A clinical examination, clinical photography and a questionnaire were applied to 201 extractive mining workers. The T-student’s, ANOVA one-way, Fisher’s exact and Pearson chi-squared tests were performed and the significance level was set at 5%. A high prevalence of actinic cheilitis was observed (38.8%). Length of occupational exposure to sunlight in months (169.63±112.68, p=0.002) was associated with actinic cheilitis. Most workers were Caucasian (p<0.001) and aged 37.41±12.15 years (p=0.004). The time of occupational exposure to sunlight was significant in relation to the following clinical features: atrophy (225.75±97.31; p=0.024); blurred demarcation between the vermilion border of the lip and the skin (186.68±113.15; p=0.032); vertical fissures (210.09±123.07; p=0.046); white and red spotting (199.51±91.80; p=0.004); hard consistency of the lip (225.81±122.34; p=0.012). A high prevalence of actinic cheilitis was found. Age and ethnicity were associated with the presence of AC. Severe clinical presentations of actinic cheilitis were found among participants who had worked for at least 185 months (approximately 15 years) exposed to the sun.

Abstract
BACKGROUND The aim of the present study was to assess the frequency and characterize clinic-pathologic aspects of thrombus occurring as a single lesion or in association with other oral pathologies. MATERIAL AND METHODS 122 cases of thrombus from the oral cavity were retrieved. Information regarding site of the lesion, age, sex and clinical diagnosis or hypothesis and associated lesions were collected from the patients' records. RESULTS The lesions occurred in a wide age range but the 5th decade was the most prevalent and female patients were more affected. The most frequent site for the lesion was the lip, followed by tongue, buccal mucosa, alveolar ridge, gingiva, floor of the mouth and vestibule. Thirty-five cases were associated with other vascular anomalies or actinic cheilitis. Microscopically, typical thrombus morphology was present. Organized thrombus presented neovascularization and fibroblasts, associated with hemorrhagic areas. CONCLUSIONS Only 4 cases of oral thrombus have been described in the oral cavity. Given the limited number of cases reported, the importance of a thrombus in the oral cavity is not well established. This study contributes to establishing the profile of patients presenting oral thrombus, a lesion not rare but not well documented.

Abstract
BACKGROUND Acetylation and deacetylation are the most studied covalent histone modifications resulting in transcriptional regulation with histone deacetylases (HDAC) and histone acetyltransferases (HAT) as the main associated enzymes. These enzymes overexpression induces abnormal transcription of key genes that regulate important cellular functions, such as proliferation, cell cycle regulation, and apoptosis. Thus, the expression of different HATs and HDACs has been evaluated in various cancers. OBJECTIVE To investigate HDAC1, HDAC2 and HAT1 expression in lip squamous cell carcinoma (LSCC) and actinic cheilitis (AC) and to demonstrate their correlation with DNA metyltransferases (DNMTs). MATERIAL AND METHODS Thirty cases of lip squamous cell carcinoma (LSCC), thirty cases of actinic cheilitis (AC), and 28 cases of non-neoplastic epithelium as control were selected for immunohistochemical investigation. RESULTS Nuclear HDAC2 immunopositivity was significantly higher in AC (75.07% ± 29.70) when compared with LSCC (51.06% ± 39.02). HDAC1 and HAT1 nuclear immunostaining were higher in AC, with no statistical significance. When comparing data with our previous study, we found a positive correlation between HDAC1 X DNMT1/DNMT3b, HDAC2 X DNMT3b, and HAT1 X DNMT1/DNMT3b for certain studied groups. CONCLUSION This study showed higher levels of nuclear HDAC2 immunopositivity in AC, possibly indicating that this enzyme plays a key role in lip photocarcinogenesis early stages.

Abstract
Background The studies found in the literature associate the immunoexpression of hMLH1
and hMSH2 proteins with histologic aspects, but do not correlate it with
clinical and epidemiological data. Objective To evaluate the immunoexpression of hMLH1 and hMSH2 in actinic cheilitis,
correlating it with clinical characteristics. Methods We analyzed 40 cases. Histological and immunohistochemical analyses were
performed. The following clinical variables were evaluated: gender, age
range, ethnicity, clinical aspect and occupational sunlight exposure.
Statistical evaluation included the Student t-test, while the significance
level was set at 5%. Results Greater immunoexpression of hMLH1 and hMSH2 was observed in females,
individuals aged over 40, and mixed-race/black patients. Furthermore, the
immunoexpression of these proteins was greater in actinic cheilitis with a
white-colored appearance and in patients without occupational sunlight
exposure. No statistical differences were observed for the variables
studied. Conclusion This study uncovered variations of hMLH1 and hMSH2 protein expression upon
evaluation of clinical aspects in actinic cheilitis.

Abstract
BACKGROUND Actinic cheilitis (AC) is a potentially malignant disorder of the lip caused by chronic exposure to ultraviolet radiation from the sun. OBJECTIVES To evaluate the clinical, demographic, morphological and therapeutic management in AC cases data associating to the histopathological grading. METHODS Demographic, clinical and management data of 161 patients with AC were analyzed. In biopsied cases, two calibrated examiners performed histopathological grading by binary system. RESULTS There was a prevalence of males (79.5%), aged 40 years or older (77.5%), light-skinned (85.7%), experiencing occupational exposure to sunlight (80.3%), with AC presenting clinically as white lesions (33.6%). Conservative treatment was adopted in 78 cases and biopsy in 83 cases (60.2% graded as low-risk AC). There were no significant associations between histopathological grading and gender (p= 0.509), age (p=0.416), ethnicity (p=0.388), occupational exposure to sunlight (p=1.000) or clinical presentation (p=0.803). CONCLUSION This study reinforces the hypothesis that demographic and clinical characteristics of AC are not related to histopathological grading. Advice on protection from sun exposure should be encouraged to avoid progression of AC and invasive therapies.

Abstract
OBJECTIVES To evaluate the relationship between the epithelial expression of hMLH1, MDM2, and p63 in lower lip carcinogenesis, comparing the immunostaining of these proteins in cases of actinic cheilitis (AC) and lower lip squamous cell carcinoma (SCC). STUDY DESIGN Forty cases of AC and 40 cases of SCC were studied, both lesions were of lower lip. Histological sections of 3 μm were submitted to immunoperoxidase method, and 1000 cells were counted for immunohistochemical analysis of lesions. The results were analyzed quantitatively, and expression was compared by the Mann-Whitney, Student t-test, or one-way ANOVA, adopting a level of significance of 5%. RESULTS A higher percentage of epithelial cells expressing hMLH1 was observed in cases of AC without dysplasia or mild dysplasia (721.23 ± 88.116), whereas fewer positive cells were observed in lower lip SSCs (255.03 ± 199.47) when compared to the AC group (P < 0.001). Immunoexpression of MDM2 was higher in SCCs of the lower lip compared with AC (P = 0.019). For p63 protein, the expression was higher in AC than in SCC (P = 0.045). CONCLUSION The present results showed changes in the immunoexpression of hMLH1, MDM2, and p63 in epithelial cells from premalignant and malignant lip disease, supporting the hypothesis that these alterations are related to the process of lower lip carcinogenesis.

Abstract
All other factors being equal, the presence of actinic cheilitis, a pre-invasive malignant lesion of the lips, doubles the risk of squamous cell carcinoma developing in this anatomic area. Various forms of local ablation,immunomodulation and surgical extirpation have been proposed as therapeutic interventions. This paper critically evaluates the available medical literature to highlight the evidence-based strength of each recommended therapy for actinic cheilitis. Vermilionectomy remains the gold standard for efficacy; trichloroacetic acid application is easy and convenient, but the least efficacious overall.
