Malignant tumors of the eyelid in India: A multicenter, multizone study on clinicopathologic features and outcomes

Neoadjuvant chemotherapy for advanced eyelid and periocular sebaceous gland carcinoma: a study of 25 cases

PURPOSE

To report the outcomes of platinum-based neoadjuvant chemotherapy (NACT) for eyelid and periocular sebaceous gland carcinoma (eSGC).

METHODS

Retrospective study of 25 patients.

RESULTS

The mean age at presentation of eSGC was 59 years. The mean tumor basal diameter was 46 mm. By the 8th edition of AJCC classification, tumors belonged T2 (n = 2, 8%), T3 (n = 6, 24%), and T4 (n = 17, 68%); N1 (n = 12,48%); and M1 (n = 1, 4%). NACT with 5-fluorouracil (5-FU) and cisplatin/carboplatin was administered in 21 (84%)/4 (16%) patients, respectively. The mean number of cycles of neoadjuvant systemic chemotherapy per patient was 2 (median, 3). The mean percentage reduction of tumor basal volume after neoadjuvant chemotherapy was 65% (median, 60%). After NACT, 12 (48%) patients underwent surgical treatment, 6 (12%) patients underwent EBRT, and 4 (8%) underwent adjuvant chemotherapy. A total of 11 (44%) patients were lost to follow-up during the course of treatment, of whom 3 died from metastatic disease. In 16 patients followed up for ≥ 3 months, complete tumor control was achieved in 11 (69%) patients, local tumor control in 14 (88%), and globe salvage in 7 (44%) at a mean follow-up of 25 months (median, 7 months; range, 3 to 110 months). No tumor recurrence was seen in any case. One (4%) serious adverse event of cardiotoxicity was noted.

CONCLUSION

Platinum-based NACT is a suitable option for eSGC with advanced tumors and locoregional metastasis. Adverse events are rare and in patients compliant with treatment, NACT-based combination therapy offers globe salvage and systemic tumor control.

Eyelid sebaceous gland carcinoma: a protocol for a systematic review and meta-analysis of clinicopathological studies of prevalence

INTRODUCTION

Sebaceous gland carcinoma (SGC) of the eyelid is an aggressive tumour with the ability to metastasise and an increased morbidity. Controversies regarding the epidemiology of this malignant eyelid tumour is widespread in the scientific literature. Western reports repeatedly describes eyelid SGC as a rare occurring tumour in general, accounting for 1%-3% of all eyelid tumours, however studies from Asia have uncovered a higher frequency of eyelid SGC including 54% of all eyelid tumours in Japan, and 43%-56% in India. We wish to retrieve observational data of eyelid SGC prevalence in proportion to total eyelid tumours, from pathological studies published worldwide to resolve this controversy.

METHODS AND ANALYSIS

We will search Ovid Medline, EMBASE, Cochrane Central Register of Controlled Trials, Scopus and Google Scholar to identify published reports on eyelid SGC prevalence proportions, aiming to clarify the incidence of the tumour. We will include observational clinicopathological studies reporting prevalence with confirmed histopathology. No limitations on publication date or language will be applied. Data from the individual studies and study quality will be extracted by two individual reviewers. Study quality will be assessed using the JBI Critical Appraisal Instrument for Studies Reporting Prevalence Data. Raw proportions will be transformed and pooled using a random effects model for meta-analysis. And subgroup analysis according to geography will be performed. If data are deemed unsuitable for a meta-analysis, a narrative synthesis will be presented. We will judge the certainty of evidence and present whether this has an overall effect on the results. The results may shed light on a long-standing academic disparity of the scientific literature.

ETHICS AND DISSEMINATION

This systematic review does not require ethical approval. The results of this proposed review will be the subject to a publication in an international peer-reviewed journal within the ophthalmic or pathological specialty.

HPV-Associated Squamous Cell Carcinoma of the Eyelid: Diagnostic Utility of p16 Immunohistochemistry and mRNA In Situ Hybridization

BACKGROUND

High-risk (HR) Human papillomavirus (HPV) has been implicated in pathogenesis of squamous cell carcinomas (SCC) at several sites with mucocutaneous junctions, including the head and neck. SCC is the second most common eyelid malignancy. However, its association with transcriptionally active HR-HPV has not been adequately studied.

METHODS

Two index cases of eyelid HPV-associated SCC are described in detail. A retrospective cohort of eyelid SCC was examined for p16 immunoexpression. Cases demonstrating p16 positivity or equivocal staining were subjected to high-risk HPV mRNA in situ hybridization (ISH). Quantitative real-time PCR (qPCR) was performed in mRNA ISH-positive cases for HPV genotyping.

RESULTS

The two index patients were older adult females, with upper eyelid tumours. On histology, both tumours were non-keratinizing SCC with trabecular and nested architecture reminiscent of oropharyngeal HPV-associated non-keratinizing SCC, prompting p16 immunohistochemistry, which was positive. HR-HPV mRNA ISH was positive, and qPCR detected HPV16 in both cases. Three of 20 (15%) archival cases showed p16 immunopositivity and two (10%) showed equivocal staining. However, mRNA ISH was negative. All cases showing p16 immunostaining and lacking HR-HPV were keratinizing SCCs. Thus, 9% of all eyelid SCC examined demonstrated HR-HPV.

CONCLUSION

The prevalence of HR-HPV in eyelid SCC is low in Indian patients. HPV-associated SCC may mimic commoner eyelid carcinomas as it lacks overt keratinization. In basaloid-appearing eyelid carcinomas, p16 immunopositivity should be followed by reflex HR-HPV mRNA ISH, as p16 immunohistochemistry alone has low specificity. The prognostic role, if any, of HPV association needs further evaluation.

Prevalence of and Associated Factors for Eyelid Cancer in the American Academy of Ophthalmology Intelligent Research in Sight Registry

PURPOSE

To estimate the prevalence of eyelid cancers in the American Academy of Ophthalmology Intelligent Research in Sight (IRIS) Registry and evaluate the associated factors.

DESIGN

Retrospective IRIS Registry database study.

PARTICIPANTS

All patients in the IRIS Registry between December 1, 2010, and December 1, 2018, with International Classification of Disease, ninth and 10th revisions, codes for eyelid cancers (basal cell carcinoma [BCC], squamous cell carcinoma [SCC], malignant melanoma [MM], sebaceous carcinoma/other specified malignant neoplasm [SBC], melanoma in situ [MIS], and unspecified malignant neoplasm [UMN]).

METHODS

The prevalence of each eyelid cancer type was estimated overall and by age group, sex, race, ethnicity, and smoking status. The associations between any eyelid cancer (AEC) or each cancer type and possible risk factors were examined using univariate and multivariate logistic regression models.

MAIN OUTCOME MEASURES

Prevalence of and associated factors for each eyelid cancer type.

RESULTS

There were 82 136 patients with eyelid cancer identified. The prevalence of AEC was 145.1 per 100 000 population. The cancer-specific prevalence ranged from 87.9 (BCC) to 25.6 (UMN), 11.1 (SCC), 5.0 (SBC), 4.1 (MM), and 0.4 (MIS) per 100 000 population. The prevalence of AEC and each cancer type increased with increasing age (all P < 0.0001), and the prevalence of AEC, BCC, SCC, and MM was higher in males (all P < 0.0001), MIS (P = 0.02). The prevalence of BCC, SCC, MM, SBC, and AEC was highest in Whites versus that in patients of any other race (all P < 0.0001). In the multivariate logistic regression model with associated risk factors (age, sex, race, ethnicity, and smoking status), AEC was associated with older age groups ([< 20 years reference {ref.}]; odds ratio [95% confidence interval]: 20-39 years: 3.35 [1.96-5.72]; 40-65 years: 24.21 [14.80-39.59]; and > 65 years: 42.78 [26.18-69.90]), male sex (female [ref.]; 1.40 [1.33-1.48]), White race (inverse associations with African Americans [0.12 {0.09-0.16}], Asians [0.19 {0.13-0.26}], others [0.59 {0.40-0.89}]), and ethnicity (non-Hispanic [ref.]; Hispanic: 0.38 [0.33-0.45]; unknown: 0.81 [0.75-0.88]). Active smoking (never smoker [ref.]) was associated with AEC (1.11 [1.01-1.21]), BCC (1.27 [1.23-1.31]), SCC (1.59 [1.46-1.73]), and MM (1.26 [1.08-1.46]).

CONCLUSIONS

This study reports the overall and cancer-specific prevalence of eyelid cancers using a large national clinical eye disease database. Smoking was found to be associated with AEC, BCC, SCC, and MM, which is a new observation. This epidemiologic profile of on-eyelid cancers is valuable for identifying patients at a higher risk of malignancy, allocating medical resources, and improving cancer care.

Clinicopathological features of patients with wide local excision of eyelid malignant neoplasms: a more than five years retrospective study from China

Background

To investigate the correlation between the clinical and pathological characteristics and outcomes in patients with eyelid malignant tumors underwent wide local excision.

Methods

This retrospective study included 141 cases of eyelid malignant neoplasms from January 2010 to December 2015 in Shanxi eye hospital. Demographic and clinical information were collected. The Kaplan–Meier method was used to calculate survival curves, and the log-rank test method was used to compare survival between groups. Cox proportional regression models were used to calculate the hazard ratios (HR) of total recurrence rate and metastasis rate.

Results

Overall, there were 141 eyelid malignant neoplasms cases aged 65.34 ± 9.69 (range, 41—88) years old. The duration time range was from 1 to 828 (61.09 ± 122.21) months. Basal cell carcinoma (BCC) is the most common of all eyelid malignancies, accounting for 84 (59.5%), followed by Sebaceous gland carcinoma (SGC, 41, 29%), Squamous Cell Carcinoma (SCC, 11, 7.8%), Malignant Melanoma (MM, 3, 2.1%)。On cox-regression analysis, pathological classification (HR 1.959; 95% CI 1.012–3.790; p = 0.046) and eyelid tumor surgery history (HR 17.168; 95% CI 1.889–156.011; p = 0.012) were independently associated with recurrence in patients with eyelid malignant neoplasm. Pathological classification (HR 2.177; 95% CI 1.423 -3.331; p < 0.001) was independently associated with metastasis in patients with eyelid malignant neoplasm. Recurrence and metastasis were most likely to occur in 3 years after surgery.

Conclusion

Wide local excision is an effective and economical treatment for eyelid malignant neoplasms. The prognosis is mainly related to pathological types, eyelid tumor surgical history and TNM stages.

The epidemiology of adults' eyelid malignancies in Germany between 2009 and 2015; An analysis of 42,710 patients' data

PURPOSE

We report the incidence of malignant tumors of the eyelid in Germany between 2009 and 2015.

METHODS

Data pertaining to the period between 2009 and 2015 were extracted from the German Cancer Registry. The International Classification of Diseases for Oncology-3 codes for tumors of the eyelid or canthus were used to identify incidence rates and survival probabilities. Crude and age-standardized incidence rates (ASR) were calculated by age, year, and gender and the individual federated states. Survival was calculated using the Kaplan-Meyer and Life tables methods, and COX-Regression was used to calculate hazard ratios for overall and cancer-specific survival.

RESULTS

This study examined data pertaining to 42,710 patients who had been diagnosed with malignant tumors of the eyelid. Basal cell carcinoma was by far the most common tumor of the eyelid (87.1%), followed by squamous cell carcinoma (10.1%) and malignant melanoma (1.1%). ASRs of basal cell carcinoma, squamous cell carcinoma, and melanoma were 65.1, 7.49, and 0.83 per million, respectively. Sebaceous cell carcinoma did not appear to be of high prevalence in Germany. Cancer-specific survival was generally high, exceeding 95%. The overall survival of patients with melanoma was considerably lower than those with other cancers. Both survival rates were inferior to that of basal cell carcinoma (74.9%). Cancer-Specific survival at five years for all groups exceeded 95%.

CONCLUSIONS

The incidence rates of malignant lid tumors match that of the European countries but shows a different pattern than Asian countries.

Chondrocutaneous conchal graft for optimal reconstruction of full-thickness lower eyelid defect: a reconstructive challenge

Non-melanoma skin cancers of the head and neck region require optimal management encompassing oncological safety, minimal functional and cosmetic morbidity. The eyelid reconstruction poses a reconstructive challenge as it should include both anatomical and functional integrity. Full-thickness eyelid defects post resection can be managed with chondrocutaneous grafts. We present to you a case of a man in his 70s, who presented with left lower eyelid squamous cell carcinoma, who had a full-thickness eyelid defect, post ablative resection. Composite chondrocutaneous conchal graft with forehead flap was used to provide adequate functional and cosmetic outcomes. The patient has normal vision, with no exposure keratitis and complications.

The spectrum and clinicopathological correlation of eyelid lesions: Twenty years' experience at a tertiary eye care center in South India

Purpose:

To study the epidemiological pattern and diagnostic accuracy of histopathologically proven eyelid lesions over a period of two decades.

Methods:

A retrospective study of all histopathologically proven eyelid lesions from April 1996 to March 2016 was conducted. The lesions were broadly categorized as benign or malignant. Inflammatory and infectious lesions were included under the benign category. The percentage and diagnostic accuracy of each lesion was calculated.

Results:

There were a total of 994 (M = 551, F = 443) cases. The mean age of the patients was 43.5 ± 19.9 years. There were 809 (81.4%) benign and 185 (18.6%) malignant lesions. Benign lesions were commonly seen in the fourth decade, while the malignant ones in the late fifth decade. The upper lid was the most common site in both groups (n = 481, 48.4%). The commonest benign lesion was chalazion (n = 484, 59.8%). Dermal nevus (n = 94, 11.6%) was the most common benign neoplasm, while Molluscum contagiosum (n = 25, 3.09%) was the most common infectious lesion. Sebaceous gland carcinoma (SGC) (n = 103, 55.7%) was the leading malignant lesion followed by basal cell carcinoma (n = 39, 21.1%). Eleven malignant cases were misdiagnosed as benign (5.9%). Chalazion (99.1%) and SGC (65%) had the highest diagnostic accuracy, while Molluscum (40%) and squamous cell carcinoma (40%) were the most misdiagnosed lesions in the respective groups.

Conclusion:

Benign eyelid lesions are far more common than malignant ones. Atypical and rare presentations may lead to misdiagnosis. Knowledge of epidemiological patterns and clinical features can help in achieving higher diagnostic accuracy.

Adipophilin expression in skin lesions with clear cell histology

AIMS

Clear cells formed due to depositions of glycogen or lipids in the cytoplasm commonly occur in various tissues. Adipophilin (ADP), a lipid regulatory protein, is closely related to lipid droplets. This study aims to examine adipophilin expression in clear cells of various skin lesions.

METHODS

ADP expression was examined using immunohistochemistry in 108 sections from 15 skin lesion types with clear cell histology, namely, sebaceoma (n=16), sebaceous adenoma (n=3), sebaceous carcinoma (n=12), xanthomata cutis (n=10), xanthogranuloma (n=8), Paget's disease (n=10), Bowen disease (n=10), hidradenoma (n=9), atypical lipoma (n=5), superficial lipomatous nevus (n=5), metastatic renal cell carcinoma (n=5), squamous cell carcinoma (n=4), seborrheic keratosis (n=4), dermatofibroma (n=4) and clear cell sarcoma (n=3).

RESULTS

ADP was not expressed in Bowen disease, hidradenoma or seborrheic keratosis. Four expression patterns, foamy, reticular, granular and punctate, were summarised based on their expression in clear cells. Different expression patterns were related to tissue origin and differentiation degree. Foamy expression was commonly observed in lesions with mature sebaceous glands and xanthomas; reticular expression in adipocytes; granular expression in xanthoma, xanthogranuloma and metastatic renal carcinoma and punctate expression in sebaceoma, sebaceous carcinoma, Paget's disease, squamous cell carcinoma and clear cell sarcoma. Furthermore, stronger staining with focal vesicular labelling was noted in sebaceoma than in sebaceous carcinoma. Characteristic labelling was noted, including the circular distribution in Touton giant cells of xanthogranulomas and focal distribution in the clear cells along the edge of necrotic tissue in clear cell sarcoma.

CONCLUSIONS

ADP is useful in identifying intracytoplasmic lipids and can be used to diagnose skin lesions with clear cell histology, especially in some lesions with characteristic labelling.
