Mohs micrographic surgery for eyelid sebaceous carcinoma: A multicenter cohort of 360 patients.

BACKGROUND: The decision to perform Mohs micrographic surgery (MMS) or wide local excision (WLE) for eyelid sebaceous carcinoma (SC) is controversial. OBJECTIVE: To compare local recurrence, metastasis, and tumor-related mortality of patients with eyelid SC who were initially treated with MMS versus with WLE. METHODS: A multicenter cohort study. Medical records were reviewed for factors associated with recurrence, metastasis, and tumor-related mortality. All eligible patients were followed up. The impact of initial surgical modality on the prognoses were determined by Cox analyses after control for all confounders. RESULTS: Of the 360 patients included in this cohort, 115 (31.9%) underwent MMS as primary resection, whereas 245 (68.1%) underwent WLE. After a median follow-up period of 60.0 months, local recurrence was observed in 18 patients (15.7%) in the MMS group and 97 patients (39.6%) in the WLE group. Metastasis occurred in 9 patients (7.8%) who underwent MMS and 38 (15.5%) who underwent WLE. In all, 6 patients in the MMS group (5.2%) and 21 in the WLE group (8.6%) died of metastatic SC. Multivariable Cox regression indicated that compared with the WLE group, the MMS group exhibited more favorable local recurrence control (hazard ratio [HR], 0.42; 95% confidence interval [CI], 0.24-0.73; P = .002) but a comparable metastasis rate (HR, 1.38; 95% CI, 0.60-3.18; P = .453) and comparable tumor-related mortality (HR, 1.70; 95% CI, 0.59-4.93; P = .329). However, this beneficial effect became nonremarkable for patients with pagetoid intraepithelial neoplasia (HR, 1.73; 95% CI, 0.37-8.21; P = .488). LIMITATIONS: Retrospective nature of the study. CONCLUSION: MMS should be proposed for eyelid SC without orbital involvement to achieve recurrence control; however, this surgical procedure did not change the long-term outcomes in terms of metastasis or tumor-related mortality. Patients with pagetoid intraepithelial neoplasia may require adjuvant measures.

Impact of clinicopathologic factors on survival in patients with sebaceous carcinoma of the eyelid - a population-based analysis.

Purpose: To evaluate prognostic factors and survival of patients with sebaceous carcinoma of the eyelid through a population-based analysis. Methods: A total of 940 patients with primary sebaceous carcinoma of the eyelid were derived from the Surveillance, Epidemiology, and End Results (SEER) database in the United States from 1973 to 2013. Kaplan-Meier univariate analysis and Cox Regression multivariate analysis were performed to examine prognostic factors in overall survival (OS). 5- and 10-year survival rates, median survival, and prognostic variables with statistical significance were measured. Results: Kaplan-Meier analysis showed that OS is 66% and 44% at 5 years and 10 years respectively. Median OS is 9.4 years. Multivariate Cox regression analysis demonstrated that independent prognostic factors for OS are age at diagnosis (HR = 4.61 [95% CI 1.93-11.0], P = 0.001), surgical treatment (HR = 0.196 [95% CI 0.07-0.55], P = 0.002), combined surgical and radiation treatment (HR = 0.227 [95% CI 0.06-0.81], P = 0.023), and greater tumor size at diagnosis (HR = 3.381, [95% CI 1.77-6.45], P < 0.001). Conclusion: We report the largest population study to date to evaluate prognostic factors of patients with sebaceous carcinoma of the eyelid. Multivariate analysis shows that older age, and greater tumor size correlate with decreased overall survival, whereas surgical treatment or combined surgical and radiation treatment correlate with increased overall survival. Interestingly, tumor grade, lymph node involvement, and distant extent of tumor have not demonstrated to be independent prognostic factors for overall survival.

Treatment of Metastatic Eyelid Carcinoma.

PURPOSE: The aim of this study was to report management and outcomes in patients affected by eyelids carcinomas involving regional lymph nodes. METHODS: We have retrospectively analyzed the data of patients affected by eyelids carcinoma with nodal involvement. The clinical records of 10 patients with malignant eyelid carcinoma and regional nodal metastasis treated between September 2011 and March 2015 have been analyzed. RESULTS: The study included 5 women and 5 men (median age 54,5 years; range 37-80 years). The most common tumor was the squamous cell carcinoma (4 cases) followed by sebaceous carcinoma (2 cases): 1 case of epidermoid carcinoma, 1 case of malignant melanoma, 1 case of Merkel carcinoma, and 1 case of basal cell carcinoma. All patients were treated by surgical resection; in 2 cases, orbital exenteration was required. The treatment of regional nodal metastasis consisted of parotidectomy and radical neck dissection followed by radiation therapy. None of the patients developed local recurrence. Three patients died: one, affected by Merkel cell carcinoma, died after 2 months because of metastatic dissemination to the lung; another one, affected by epidermoid carcinoma involving the orbit, died because of liver metastasis; the third one, affected by malignant melanoma, died because of other causes. The follow-up time ranged from 9 to 36 months (median 19.3 months). CONCLUSIONS: Patients affected by advanced malignant eyelid carcinoma need to be strictly controlled because metastasis can develop at least 5 years after surgical treatment. Therapy may include a combination of local surgery, neck dissection, and radiation.

Effect of Non-Hodgkin Lymphoma on Survival in Patients With Malignant Fibrous Histiocytoma, Kaposi Sarcoma, and Sebaceous Carcinoma: A SEER Population-Based Study.

OBJECTIVE: To quantify the behavior of dermatofibrosarcoma protuberans (DFSP), malignant fibrous histiocytoma (MFH), Kaposi sarcoma (KS), and sebaceous carcinoma (SC) in patients with a history of non-Hodgkin lymphoma (NHL). PATIENTS AND METHODS: Subjects with a diagnosis of DFSP, MFH, KS, or SC between 1990 and 2006 were identified in the Surveillance, Epidemiology, and End Results Program database. For each skin cancer type, the standardized mortality ratio (SMR) for death due to any cause and death due to skin cancer was estimated. RESULTS: From 1990 through 2006, 25,357 skin cancers were identified: 4,192 DFSP, 6,412 MFH, 10,543 KS, and 4,222 SC. For patients with a history of non-CLL NHL, SMRs for death due to any cause were 1.45 (95% confidence interval [CI], 1.03-2.04; p = 0.04) for MFH, 2.90 (95% CI, 2.50-3.36; p < 0.001) for KS, and 3.25 (95% CI, 1.84-5.75; p < 0.001) for SC and SMRs for death due to skin cancer were 0.55 (95% CI, 0.23-1.31; p = 0.18) for MFH, 2.93 (95% CI, 2.49-3.43; p < 0.001) for KS, and 4.07 (95% CI, 1.28-12.94; p < 0.001) for SC. CONCLUSION: Among patients with KS and SC, patients with a history of non-CLL NHL have a greater risk of overall and cause-specific death than expected.

Prognosis of eyelid sebaceous gland carcinoma based on the tumor (T) category of the American Joint Committee on Cancer (AJCC) classification.

The purpose of this study was to evaluate the clinical features and prognosis of eyelid sebaceous gland carcinoma (SGC) based on the T category of the American Joint Committee on Cancer (AJCC) classification (7th edition). This is a retrospective interventional case series study. Based on the T category of the AJCC classification, 191 patients with eyelid sebaceous gland carcinoma were classified as T1 (n = 1, 1 %), T2 (n = 111, 58 %), T3 (n = 76, 40 %), and T4 (n = 3, 2 %). Based on multivariate analysis, the factors predictive of regional lymph node metastasis included duration of symptoms >6 months (p = 0.04) and orbital tumor extension (p < 0.001). The factors predictive of systemic metastasis included orbital tumor extension (p < 0.001) and perivascular invasion (p = 0.007). The factor predictive of death due to systemic metastasis included orbital tumor extension (p < 0.001). Kaplan-Meier estimates of regional lymph node metastasis at 5 and 10 years, respectively, were 0 and 0 % for T1, 11 and 11 % for T2, 44 and 59 % for T3, and 100 and 100 % for T4 (p < 0.001). Kaplan-Meier estimates of systemic metastasis at 5 and 10 years, respectively, were 0 and 0 % for T1, 6 and 6 % for T2, 35 and 35 % for T3, and 100 and 100 % for T4 (p < 0.001). Kaplan-Meier estimates of death due to metastasis at 5 and 10 years, respectively, were 0 and 0 % for T1, 3 and 3 % for T2, 30 and 50 % for T3, and 100 and 100 % for T4 (p < 0.001). Primary tumor (T) category of the AJCC classification predicts the prognosis of patients with eyelid SGC. The risk of systemic metastasis and death increases with increasing tumor category.

American Joint Committee on Cancer T category for eyelid sebaceous carcinoma correlates with nodal metastasis and survival.

PURPOSE: To determine whether T category of the American Joint Committee on Cancer (AJCC) TNM staging system for eyelid carcinoma, 7th edition, correlates with lymph node metastasis, distant metastasis, and survival in patients with sebaceous carcinoma of the eyelid. DESIGN: Retrospective, cohort study. PARTICIPANTS: Fifty consecutive patients treated by 1 author (BE) for eyelid sebaceous carcinoma between May 1999 and August 2010. METHODS: Each tumor was staged according to the AJCC 7th edition TNM criteria. The Kaplan-Meier method was used to determine associations between disease-specific survival and (1) T category at presentation, (2) lymph node metastasis, and (3) distant metastasis. MAIN OUTCOME MEASURES: T category at presentation, nodal metastasis, survival. RESULTS: The study included 37 women and 13 men (median age, 68.5 years; range, 44-86 years). Forty-four patients were white, 5 were Hispanic, and 1 was Asian. TNM designations were TXN0M0, 7 patients; T1N0M0, 4 patients; T2aN0M0, 12 patients; T2bN0M0, 11 patients; T2bN1M0, 2 patients; T2bN1M1, 1 patient; T3aN0M0, 2 patients; T3aN1M0, 5 patients; T3bN0M0, 1 patient; T3bN1M0, 1 patient; T3bN0M1, 2 patients; T4N0M0, 1 patient; and T4N0M1, 1 patient. T category at presentation was significantly associated with lymph node metastasis (P = 0.0079). No tumors with T category better than T2b or smaller than 9 mm in greatest dimension were associated with nodal metastasis. Five patients (10%) died of disease during follow-up. Their TNM designations were T2bN1M1, 1 patient; T3bN0M1, 2 patients; T4N0M0, 1 patient; and T4N0M1, 1 patient. No tumors smaller than 12 mm in greatest dimension were associated with distant metastasis or death. T category was significantly associated with disease-specific survival (P = 0.0009). Disease-specific survival was poorer among patients with T category of T3a or worse (P = 0.035). CONCLUSIONS: T category in the 7th edition of the AJCC TNM staging system for eyelid carcinoma correlates with outcomes in patients with sebaceous carcinoma of eyelid. On the basis of the present findings, it seems reasonable to recommend sentinel lymph node biopsy or at least strict regional lymph node surveillance for patients with eyelid sebaceous carcinoma with tumors of T category T2b or worse or 10 mm or more in greatest dimension.

Radiation therapy for primary carcinoma of the eyelid: tumor control and visual function.

BACKGROUND AND PURPOSE: Surgical excision remains the standard and most reliable curative treatment for eyelid carcinoma, but frequently causes functional and cosmetic impairment of the eyelid. We therefore investigated the efficacy and safety of radiation therapy in eyelid carcinoma. PATIENTS AND METHODS: Twenty-three patients with primary carcinoma of the eyelid underwent radiation therapy. Sebaceous carcinoma was histologically confirmed in 16 patients, squamous cell carcinoma in 6, and basal cell carcinoma in 1. A total dose of 50-66.6 Gy (median, 60 Gy) was delivered to tumor sites in 18-37 fractions (median, 30 fractions). RESULTS: All but 3 of the 23 patients had survived at a median follow-up period of 49 months. The overall survival and local progression-free rates were 87% and 93% at 2 years, and 80% and 93% at 5 years, respectively. Although radiation-induced cataracts developed in 3 patients, visual acuity in the other patients was relatively well preserved. There were no other therapy-related toxicities of grade 3 or greater. CONCLUSION: Radiation therapy is safe and effective for patients with primary carcinoma of the eyelid. It appears to contribute to prolonged survival as a result of good tumor control, and it also facilitates functional and cosmetic preservation of the eyelid.

Impact of surgery and adjuvant treatment on the outcome of extraocular sebaceous carcinoma: a systematic review and individual patient's data analysis of 206 cases.

BACKGROUND: Extraocular sebaceous carcinoma (EOSC) is an aggressive malignancy of the sebaceous gland. Surgery is considered the cornerstone of treatment, but there is lack of clarity about extent and adjuvant treatment. METHODS: We conducted a systematic review and analysis of individual patient data of all published cases of EOSC to look into demography, pattern of care, importance of type of surgery, and other adjuvant treatment and survival outcome. A search of PubMed and Google Scholar was done with the key words sebaceous carcinoma, extraocular sebaceous carcinoma, and Muir-Torre syndrome till December 2017. The data were compiled in an Excel chart and analyzed using SPSS IBM software. RESULTS: Data of 206 patients were retrieved. Median age at presentation was 65 years (range: 11-96 years). Surgery was performed in all except 13 patients. Of these 13, eight were deemed inoperable for extensive disease, and five had metastatic disease. Median PFS and OS for the entire cohort were 84 months (95% CI: 10-158 months) and 92 months (95% CI: 59-126 months). Univariate analysis revealed significantly poor survival for patients with a metastatic disease, regional nodal metastasis, and those with Mohs micrographic or incomplete surgery. CONCLUSION: EOSC is a disease of elderly patients with good prognosis. Complete surgery with regional lymph node dissection is standard treatment. The role of adjuvant radiotherapy is debatable but can be considered in patients with incomplete surgery or high-risk factors.

Eyelid carcinoma: An experience from a tertiary cancer center.

CONTEXT: Eyelid carcinoma is rare tumors of the head and neck. They are rarely lethal but can be associated with significant morbidity if not treated early and appropriately. There are limited data available from world over and in particular the Indian subcontinent regarding eyelid carcinoma and its prognostic factors influencing treatment outcomes. Setting and Design:Retrospective study of patients treated in a tertiary cancer center between 2005 and 2016. METHODOLOGY: In this study, 51 patients with eyelid carcinoma treated at single tertiary cancer center were included. The demographic, clinical data, which includes the treatment received, histopathology report and follow-up, were recorded. All the relevant variables influencing disease-free survival (DFS) were analyzed. RESULTS: Sebaceous carcinoma was the most common eyelid carcinoma followed by squamous cell carcinoma and basal cell carcinoma in descending order in this series. Lower eyelid was involved most often. The incidence of nodal metastasis was low (14%). Multivariate analysis revealed that margin status influenced the DFS (P= 0.001) (hazard ratios = 15.9 [95% confidence interval: 1.8-135.2]). The 5 years' DFS was 70%. CONCLUSION: Eyelid tumors are less common cancer with good prognosis if treated appropriately. The morbidity associated with treatment can be reduced if treated early.

Evaluation of PD-L1 and PD-1 expression in aggressive eyelid sebaceous gland carcinoma and its clinical significance.

Purpose: Eyelid sebaceous gland carcinoma (SGC) is an aggressive but rare malignancy of ocular region. Over-expression of PD-L1 and PD-1 has been demonstrated in a variety of solid tumors including conjunctival melanoma. PD-L1 is an immunoinhibitory molecule that suppresses the effective T cells response against tumor antigen leading to the progression of tumors. Inhibitors of the interaction of PD-L1 and PD-1 are associated with good clinical response various carcinomas. The prognostic value of the PD-1/PD-L1 axis in SGC remains unexplored. The purpose of this study was to evaluate expressions of PD-1 and its ligand PD-L1 in SGC and correlate its expression with clinicopathological features and patients survival. Methods: The immunohistochemical expression of PD-L1 and PD-1 was evaluated in 30 SGC cases. Results: PD-L1 immunopositivity was detected in 41.9% of the SGC cases. PD-1 expression in tumor infiltrative lymphocytes (TILs) was observed in 53.3% samples. Tumor PD-L1 positivity, PD-1 expression in TILs and tumor size (>10 mm) was associated with reduced disease-free survival. On multivariate analysis only tumor size (>10 mm) and a combined positivity of PD-L1 in tumor cells and PD-1 in TILs with an odds ratio of 5.212 (95% confidence interval 1.449-18.737) continued to be significantly associated with SGC recurrence. Conclusion: PD-L1 is overexpressed in 50% of SGC cases. The combined tumor PD-L1 positivity and TILs showing PD-1 expression within the same SGC patient's samples predict high-risk SGC, suggesting that the up-regulation of PD-L1 in tumor cells and PD-1 positivity within the same SGC patient may aggravate tumor recurrence.

Eyelid sebaceous carcinoma: Validation of the 8th edition of the American Joint Committee on cancer T staging system and the prognostic factors for local recurrence, nodal metastasis, and survival.

PURPOSE: To investigate the clinicopathological features and prognostic factors for eyelid sebaceous gland carcinoma (SGC) in an ethnic Chinese population and to validate the performance of the T category of the 8th edition AJCC staging systems, with the aim of providing information for refinements. METHODS: Sixty-three patients with pathological diagnosis of SGC were enroled retrospectively. The clinicopathological features, treatments, and outcomes were collected. Prognostic factors associated with the outcome of local recurrence, regional lymph node metastasis, and tumour-related death were analysed. The performance analysis was performed by comparing the predictive value for survival and the monotonicity of gradients between the 7th and 8th staging systems. RESULTS: The distribution of T1:T2:T3:T4 tumours according to the 7th and 8th edition was 6:40:16:1 and 23:26:5:9, respectively. Positive surgical margin was a poor prognostic factor. Local recurrence was associated with more aggressive histopathological features and surrounding structure invasions. Regional lymph node metastasis was associated with larger tumours. The T category of 8th edition showed better predictability for local recurrence and regional lymph node metastasis, while the T category of 7th edition had better monotonicity of gradients. Tumours classified as T2c or worse had higher risk of regional lymph node metastasis, while tumours T3b or worse in the 8th edition had more tumour-related death. CONCLUSIONS: Patients with higher T category are at risk of regional lymph node metastasis and tumour-related death. Further refinement of the T category of AJCC staging system can focus on the predictability for local recurrence and the monotonicity of gradients.

14-year case series of eyelid sebaceous gland carcinoma in Chinese patients and review of management.

AIMS: Sebaceous gland carcinoma (SGC) of the eyelid is a rare but potentially deadly cancer. The purpose of this study was to determine whether the American Joint Committee on Cancer (AJCC) 7th Edition T category for SGC correlated with metastasis and survival in the Chinese population. METHODS: This was a retrospective, single-centre cohort study. Patients with surgically resected eyelid SGC between January 2001 and May 2015 at the Hong Kong Eye Hospital were reviewed. Tumours were staged using the AJCC criteria. The main outcome measures included local recurrence, metastasis and death. Disease-free survival (DFS) was measured from the completion of treatment; overall survival was measured from the date of initial diagnosis. RESULTS: The study included 22 Chinese patients with a mean age of 65.4 years. The majority presented as a nodular lesion (91%) with 12 eyes (54.5%) initially misdiagnosed and a mean presentation time of 1 year. It was found that those with AJCC stage T2b or higher were significantly associated with lymph node metastasis (P=0.002) when compared with those with stage T2a. Older age at diagnosis (P=0.035) and no misdiagnosis (P=0.025) were associated with shorter DFS. Those with stage 3a or higher were associated with shorter DFS (P=0.007) and overall survival (P=0.024). CONCLUSION: Similar to previous reports, in this Chinese cohort, AJCC staging for SGC correlated with lymph node metastasis, DFS and overall survival. Those with stage 2b or higher on presentation will need closer surveillance for lymph node metastasis and may benefit from sentinel lymph node biopsy.

ZEB2/SIP1 as novel prognostic indicator in eyelid sebaceous gland carcinoma.

Epithelial-mesenchymal transition (EMT) plays a pivotal role in tumor invasion and metastasis in various malignancies. ZEB2/SIP1 is an important EMT regulator and down-regulates E-cadherin expression. The present study was planned to explore status of EMT-associated markers ZEB2/SIP1 and E-cadherin in eyelid sebaceous gland carcinoma (SGC) and to correlate with clinicopathological high-risk features. Expressions of ZEB2 and E-cadherin were evaluated by immunohistochemistry in 65 cases of histopathologically proven eyelid SGC. The results were correlated with clinicopathological high-risk features and survival of the patients to determine the prognostic significance of ZEB2, E-cadherin, and various high-risk features. Cytoplasmic overexpression of ZEB2 and membranous loss of E-cadherin were seen in 68% and 66% of cases of eyelid SGC, respectively. ZEB2 overexpression was significantly associated with E-cadherin loss (P = .002). Overexpression of ZEB2 also showed significant association with lymph node metastasis (P = .046), orbital invasion (P = .049), large tumor size (P = .018), and advanced tumor stages (P = .036). Survival analysis revealed that patients with ZEB2 overexpression had poor survival. ZEB2 overexpression and orbital invasion were found to be independent prognostic indicators (univariate analysis). However, multivariate analysis showed that ZEB2 (hazard ratio, 0.094; 95% confidence interval, 00.012-0.709; P = .022) was the best poor prognostic indicator of eyelid SGC. Our study demonstrates the role of both ZEB2 and E-cadherin in the promotion of EMT in eyelid SGC. The outcome of this study also points toward ZEB2 as an independent prognostic marker as well as a potential therapeutic target in eyelid SGC.

Population-based analysis of prognostic indicators in sebaceous carcinoma of the head and neck.

OBJECTIVES/HYPOTHESIS: Due to the rarity of sebaceous carcinoma of the head and neck, few large series have been reported and prognostic factors remain largely undetermined. This study presents prognostic factors in survival in sebaceous carcinoma of the head and neck. STUDY DESIGN: Retrospective analysis was performed using the Surveillance Epidemiology and End Results (SEER) database for patients diagnosed with sebaceous carcinoma of the head and neck (SCHN). METHODS: Clinicopathologic, treatment data, and 5-year disease specific survival were analyzed using univariable and multivariable regression analysis and Kaplan-Meier methodology. RESULTS: Of the 1,433 patients identified to have SCHN, 16 were node-positive (1.14%). On multivariable analysis, independent prognostic indicators were: age at diagnosis (HR = 1.03, P = .021), tumor grade (HR = 4.97, P = .038), and distant metastasis (HR = 7.52, P = .006). Nodal metastasis occurred exclusively with poorly or undifferentiated tumors and was not a significant prognostic factor on multivariable analysis. CONCLUSION: Elderly patients and patients with poorly differentiated tumors and/or distant disease at presentation have the highest risk of disease-specific mortality. Lymph node metastasis does not appear to be an independent prognostic factor in sebaceous cell carcinoma.

Management of unusual cutaneous malignancies: atypical fibroxanthoma, malignant fibrous histiocytoma, sebaceous carcinoma, extramammary Paget disease.

Atypical fibroxanthoma, malignant fibrous histiocytoma, sebaceous carcinoma, and extramammary Paget disease are rare cutaneous tumors. Their recognition and diagnosis are critical in decreasing long-term morbidity and mortality. Surgical excision is the treatment of choice for these tumors, and Mohs micrographic surgery has been shown to be as favorable or better than wide local excision in providing long-term clearance rates.

Sebaceous cell carcinoma of the ocular adnexa: clinical presentations, histopathology, and outcomes.

PURPOSE: To investigate the clinical features, time to diagnosis, histopathology, treatment, and mortality rates of patients with sebaceous cell carcinoma. METHODS: This was a retrospective, consecutive series of patients with sebaceous cell carcinoma at a tertiary referral medical center. Between January 1984 and January 2006, 31 patients with sebaceous cell carcinoma were evaluated at the Department of Ophthalmology and Visual Sciences, University of Iowa Hospitals and Clinics. The main outcome measures were clinical presentations, treatments, reconstructive procedures, and outcomes. RESULTS: Thirty-one patients were diagnosed with sebaceous cell carcinoma of the ocular adnexa on histopathology. Twenty (65%) of the patients were women and 11 were men. The upper eyelid was involved in 18 patients, lower eyelid in 10, both upper and lower eyelids in 1, and caruncle in 2. Twenty-three patients had in situ disease, pagetoid disease, or both. Eight patients reported symptoms for <6 months and 22 had symptoms for < or = 12 months before the diagnosis of sebaceous cell carcinoma was made. Local surgical excision of the tumor as initial treatment was performed in 25 patients. Exenteration was the initial surgery performed in 4 patients. Two patients died from metastatic sebaceous cell carcinoma. CONCLUSIONS: Sebaceous cell carcinoma has varied presentations and is commonly misdiagnosed. Tumor-related deaths occurred in only 2 patients (6.7%), which is lower than previous reports and may be related to earlier detection or improved surgical excision techniques.

Improved survival rates in sebaceous carcinoma of the eyelid.

PURPOSE: To review the clinicopathological features, management, and survival rates for patients with sebaceous gland carcinoma of the eyelid, and to analyse the reasons for improved survival. METHODS: In the west of Scotland between 1975 and 2001, 32 cases were identified through the pathology index for sebaceous carcinoma. Pathology specimens were reviewed in all cases. The clinical data were obtained from hospital records and the database provided by the Regional Cancer Registry. RESULTS: A total of 22 female and 10 male patients were identified. Follow-up ranged from 6 months to 15 years, median of 4.8 years. Primary treatment involved excisional techniques in 27 cases, exenteration in two cases, enucleation in two cases, and two cases required adjuvant radiotherapy. Intraepithelial spread and masquerade presentations delayed the diagnosis. Poorly differentiated tumours were associated with an unfavourable outcome. Three patients developed local tumour recurrence and one metastatic disease. In all, 10 patients died from nontumour-related causes and one died from metastatic sebaceous carcinoma. The overall tumour mortality rate in the west of Scotland was 3%. CONCLUSIONS: From this study, patients in the west of Scotland have a better prognosis than is indicated in the literature. Astute clinical suspicion and accurate histopathological diagnosis, together with radical and aggressive surgical approaches were key factors.
