Abstract
PURPOSE Chronic inflammation is a predisposing factor for metaplastic changes and ultimately dysplasia. We describe cases of OSSN occurring in the setting of chronic ocular surface inflammation. METHODS Sixteen eyes from 14 individuals were included from one ocular oncology clinic between 2010 and 2023. Patients presented with ocular surface squamous neoplasia (OSSN) in the setting of chronic inflammation. The diagnosis of OSSN was made using anterior segment high-resolution optical coherence tomography (HR-OCT) and confirmed by histopathological analysis in all cases. RESULTS Median age on presentation was 61 [IQR 47.5-69.2] years. Eleven (86%) individuals were male and five (36%) identified as White Hispanic. Ten eyes were referred with ocular surface diagnoses including pannus (n = 4), scarring (n = 3), pterygium (n = 2), and herpetic keratitis (n = 1). Only six eyes were referred as possible neoplasia. All individuals had a history of ocular surface inflammation. The most common inflammatory conditions were ocular rosacea (seven individuals) and atopic keratoconjunctivitis (AKC) (five individuals). Two individuals were found to have bilateral OSSN, one in the setting of ocular rosacea and the other in the setting of AKC. All 16 eyes from 14 individuals were suspected to have OSSN based on HR-OCT findings which guided the location of the incisional biopsies that subsequently confirmed histopathological diagnosis in all cases. CONCLUSION OSSN may arise in the setting of chronic inflammation on the ocular surface. Identification of the tumor can be challenging in these cases, and HR-OCT can be a key diagnostic tool in detecting OSSN.

Abstract
Ocular surface squamous neoplasia (OSSN) is a common eye surface tumour, characterized by the growth of abnormal cells on the ocular surface. OSSN includes invasive squamous cell carcinoma (SCC), in which tumour cells penetrate the basement membrane and infiltrate the stroma, as well as non-invasive conjunctival intraepithelial neoplasia, dysplasia, and SCC in-situ thereby presenting a challenge in early detection and diagnosis. Early identification and precise demarcation of the OSSN border leads to straightforward and curative treatments, such as topical medicines, whereas advanced invasive lesions may need orbital exenteration, which carries a risk of death. Artificial intelligence (AI) has emerged as a promising tool in the field of eye care and holds potential for its application in OSSN management. AI algorithms trained on large datasets can analyze ocular surface images to identify suspicious lesions associated with OSSN, aiding ophthalmologists in early detection and diagnosis. AI can also track and monitor lesion progression over time, providing objective measurements to guide treatment decisions. Furthermore, AI can assist in treatment planning by offering personalized recommendations based on patient data and predicting the treatment response. This manuscript highlights the role of AI in OSSN, specifically focusing on its contributions in early detection and diagnosis, assessment of lesion progression, treatment planning, telemedicine and remote monitoring, and research and data analysis.

Abstract
OBJECTIVE To assess the efficacy and safety of topical 0.5% 5-Fluorouracil (5-FU) as a primary therapy of ocular surface squamous neoplasia (OSSN). DESIGN Retrospective study. PARTICIPANTS Patients with clinically suspected OSSN referred to a Brazilian tertiary health center between October 2015 and December 2022. METHODS After diagnostic confirmation of OSSN with exfoliative cytology, 0.5% 5-FU was administered topically 4 times daily for 2 weeks followed by a pause of 2 weeks. RESULTS A total of 54 patients were included in this study, 32 males (59.3%), mean age of 62.9 years old. Complete resolution of OSSN was achieved in 70.4%. The median number of cycles was 2 (range 1-5). Side effects were reported in 35.2%, which included eyelid erythema, conjunctival hyperemia, and punctal stenosis. None of the patients stopped treatment due to adverse effects. Patients who had partial response to 0.5% 5-FU had complementary treatment with surgery, Mitomycin-C and/or Interferon ⍺2b. Overall recurrence was 14.8%. Median follow-up was 14 months (range 2-92 months). In a multivariate Cox regression analysis, the risk of relapse was 84% lower in patients who had complete response to 0.5% 5-FU (p = 0.018). CONCLUSION Topical 0.5% 5-FU may be considered a safe and effective primary therapy for OSSN, with a low rate of side effects.

Topical 5-fluorouracil 1% for moderate to extensive ocular surface squamous neoplasia in 73 consecutive patients: Primary versus secondary treatment. Asia Pac J Ophthalmol (Phila) 2024; 13:100052. [PMID: 38521390 DOI: 10.1016/j.apjo.2024.100052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 01/27/2024] [Accepted: 02/02/2024] [Indexed: 03/25/2024] Open
Abstract
IMPORTANCE Ocular surface squamous neoplasia (OSSN) is a spectrum of malignancies that generally includes conjunctival intraepithelial neoplasia (CIN) and squamous cell carcinoma (SCC). OSSN can be treated with topical therapies including interferon α-2b (IFN), mitomycin C (MMC), or 5-fluorouracil 1% (5FU). Recently, due to unavailability of IFN and toxicity associated with MMC, therapy has shifted towards 5FU. OBJECTIVE Herein, we compare the use of 5FU 1% as a primary versus (vs) secondary treatment regimen in eyes with moderate to extensive OSSN. DESIGN SETTING AND PARTICIPANTS Retrospective cohort study of 73 consecutive patients with unilateral moderate to extensive OSSN treated at a single tertiary ocular oncology center from 2016 to 2023. Mean follow up time was 478.2 days overall, with 283.0 days for primary 5FU group and 860.3 days for secondary 5FU group. INTERVENTION Topical 5FU 1% 4 times daily for 2 weeks with option for 2-weekly extension until tumor control, either as primary treatment or as secondary treatment to surgical resection, topical IFN or topical MMC, or cryotherapy. MAIN OUTCOMES Outcome measures included tumor response, need for additional surgery, complications, and visual outcomes. RESULTS A comparison (primary vs secondary treatment) revealed no difference in mean tumor basal dimension (19.6 vs 17.2 mm, P = 0.46), thickness (3.7 vs 3.4 mm, P = 0.64), or tumor extent (4.4 vs 4.5 clock hours, P = 0.92). The primary treatment group showed greater complete tumor control (77% vs 38%, P = 0.04). Multivariable analysis comparison (primary vs secondary treatment) showed primary treatment more likely to achieve complete tumor control (P = 0.01). There was no difference in the complication rate from 5FU treatment between the groups. There was no difference in visual outcome, and no tumor-related metastasis (0%) or death (0%). CONCLUSION AND RELEVANCE Topical 5FU 1% is efficacious and safe as a primary or secondary treatment for moderate to extensive OSSN. Tumors treated with primary 5FU 1% demonstrated more complete resolution. In patients with moderate to extensive OSSN, primary treatment with topical 5FU 1% may be warranted.

Abstract
AIMS To describe the incidence and epidemiology of conjunctival squamous cell carcinoma (CSCC) in South Africa over a 25-year period (1994-2018), with particular reference to the HIV epidemic. METHODS Incident cases of histologically diagnosed CSCC were identified from the pathology-based South African National Cancer Registry. Crude and direct age-standardised incidence rates (ASIRs) per 100 000 persons (Segi World Standard Population) were calculated using national population statistics and compared by age, sex and ethnicity. Trends in the incidence and demographic features of CSCC were described and analysed. Incidence rates were compared with national HIV-related statistics for the same time period. RESULTS In total, there were 9016 reported CSCC cases (women: 56.6%, black: 86.8%, mean age: 41.5 years). The overall ASIR was 0.78 per 100 000. Two distinct epidemiological patterns were identified: (1) older white men, and (2) younger black women. There was a sixfold increase in CSCC incidence rates between 1994 and 2009 with a corresponding shift from the first to the second disease profile. Despite rising HIV seroprevalence, CSCC incidence rates have declined since 2009. A strong ecological correlation (r=0.96) between CSCC incidence and widespread antiretroviral therapy (ART) provision was identified. CONCLUSION This study highlights the evolving trends and disease burden of CSCC in South Africa. Widespread ART provision is ecologically correlated with declining CSCC rates over the last decade. These findings are in keeping with reported trends for other HIV-related cancers and have important implications for future incidence studies and public health policy.

Abstract
PURPOSE The aim of this review was to elucidate treatment preferences for ocular surface squamous neoplasia and to examine the changes in treatment modalities over the past 2 decades. METHODS An electronic survey was distributed to members of The Cornea Society, Ocular Microbiology and Immunology Group, and 4 international corneal specialist listservs. Questions examined medical and surgical treatment preferences, and results were compared with surveys administered in 2003 and 2012. RESULTS A total of 285 individuals responded to the survey; 90% of respondents were self-classified as corneal specialists. Seventy-three percent reported using primary topical monotherapy to treat ocular surface squamous neoplasia as compared with 58% in 2012 (P = 0.008). Compared with 2003, the percentage use of topical interferon significantly increased (P < 0.0001) from 14% to 55%, 5-fluorouracil increased (P < 0.0001) from 5% to 23%, and mitomycin C decreased (P < 0.0001) from 76% to 19% as a primary monotherapy. The frequency of performing excision without the use of postoperative adjunctive medical therapy decreased significantly (P < 0.0001), from 66% to 26% for lesions <2 mm, 64% to 12% for lesions between 2 and 8 mm, and 47% to 5% for lesions >8 mm from 2003 to 2022. More clinicians initiated topical immuno/chemotherapy without performing a biopsy as compared to 2003 (31% vs. 11%, P < 0.0001). CONCLUSIONS These results demonstrate a paradigm shift in the management of ocular surface squamous neoplasia. The use of primary medical therapy as a first approach has significantly increased, with a reduction in the frequency of performing surgical excision alone.

Abstract
Periocular and ocular surface nonmelanoma malignancies, including basal cell carcinoma (BCC), squamous cell carcinomas (SCC), and ocular surface squamous neoplasia (OSSN), are rare, but their management requires special considerations. The most common periocular malignancy is BCC, which constitutes 80% to 96% of tumors, followed by SCC, which represents 5% to 10% of tumors. OSSN represents a spectrum of diseases that encompass dysplastic alteration to the squamous epithelium of the eye. OSSN ranges from squamous dysplasia to conjunctival intraepithelial neoplasia/carcinoma in situ to invasive SCC, which is the most common ocular malignancy. These tumors can be staged using the eighth edition of the American Joint Committee on Cancer categorization system. The standard of care for periocular malignancies is Mohs micrographic surgery, while medical management with 5-fluorouracil (5-FU), interferon alfa-2b (INF), and mitomycin C (MMC) or "no touch" surgical excision are options for OSSN. Systemic therapies, including sonic hedgehog inhibitors for BCC and epidermal growth factor inhibitors and immune-checkpoint inhibitors for SCC, can be utilized for advanced disease. Recurrence rates are higher for periorbital and ocular malignancies than their respective cutaneous counterparts. These carcinomas and their respective treatments have unique side effects and considerations in an effort to preserve visual function.

Abstract
INTRODUCTION Ocular surface squamous neoplasia (OSSN) is the most common ocular malignancy; the pathophysiology is influenced by molecular, genetic, and epigenetic mechanisms. The incidence of OSSN is associated with the anatomy and physiology of the ocular surface, limbal stem cell configuration, limbal vulnerability, cancer stem cells, dysplasia, neoplasia, angiogenesis, invasion, and metastasis. The key etiological factors involved are human papillomavirus (HPV), human immunodeficiency virus (HIV), immunosuppression, p53 tumor suppressor gene, hypovitaminosis A, and failure of Deoxyribonucleic acid (DNA) repair mechanisms. AREAS COVERED This special report is a focussed attempt to understand the molecular mechanism, genetic and epigenetic mechanism, and diagnostic modalities for OSSN. EXPERT OPINION While these mechanisms contribute to genome instability, promoter-specific hypermethylation might facilitate and promote tumor formation by silencing tumor suppressor genes. OSSN understanding has improved with increased literature available on various genetic, molecular, and epigenetic mechanisms, although the exact genetic and epigenetic mechanisms still need to be elucidated. It is important to note that the molecular mechanisms of OSSN can vary among individuals, and further research is required to elucidate the underlying processes fully. Understanding these mechanisms is crucial for the development of targeted therapies and improved management of OSSN.

Abstract
OBJECTIVE To evaluate the midterm results of tumour resection with or without adjunctive therapy for ocular surface squamous neoplasia of the fornix, including conjunctival reconstruction with buccal mucosa and amniotic membrane. METHODS A retrospective case-series analysis including slit-lamp examination, photographic documentation, and biopsy results (repeated when clinical findings changed). Analysis centred on eye function, complications, additional procedures, and recurrence rate. Surgical technique included tumour resection and subsequent reconstruction of lost conjunctiva with buccal mucosa and amniotic membrane. RESULTS We included 83 affected eyes from 76 patients (mean age, 63.10 ± 14.45 years; 34 females) seen over a mean follow-up period of 26.56 ± 21.17 months. We achieved bulbus oculi salvage in 82 eyes (98.79%) and typically preserved visual acuity (mean 0.2 ± 0.5 logMAR and 0.3 ± 0.5 logMAR at presentation and last follow-up, respectively). Moreover, only 23 patients (27.71%) required corrective surgery for clinically relevant complications. The main complications included symblepharon (9.64%; n = 8), cicatricial ectropion (9.64%; n = 8), pannus (9.64%; n = 8), and corneal decompensation (8.43%; n = 7). Local tumour recurrence was seen in 23 patients (27.71%). CONCLUSIONS These midterm results confirm the efficacy of conjunctival reconstruction with amniotic membrane and buccal mucosa after resection of ocular surface squamous neoplasia from the fornix with palpebral and bulbar conjunctiva involvement. We not only achieved good tumour control and organ salvage with high levels of organ preservation but we also achieved good functional outcomes and acceptable recurrence rates. All clinically significant complications could be corrected in separate procedures.

Abstract
AIMS The aim of this study is to describe the demographic, presenting features and associated risk factors of ocular surface squamous neoplasia (OSSN) at a tertiary eye hospital in Johannesburg, South Africa. METHODS An interventional prospective study of patients presenting with conjunctival masses was conducted. An electronic questionnaire was completed to document demographic data, presenting history, and associated risk factors. A slit lamp examination and photos were used to document and describe the clinical features at presentation. Cases (OSSN) and controls (benign lesions) were determined by histology. RESULTS There were 130 cases and 45 controls. Median age was 44 years (IQR: 35-51) with an equal gender distribution in cases. The prevalence of HIV in cases was 74% and was strongly associated with OSSN (p < 0.001). Vascularisation, leukoplakia and pigmentation were clinical features that distinguished cases from controls. A fibrovascular morphology was strongly associated with a benign histology (p < 0.001), whereas leukoplakic and gelatinous morphologies were associated with OSSN. Conjunctival intra-epithelial neoplasia made up 82% of cases. CONCLUSION Our study describes a sample of OSSN that is young and has no gender predisposition. The majority of cases presented with CIN lesions, rather than SCC reported in other African countries. HIV was the most significant risk factor in this study population.

Abstract
INTRODUCTION Ocular surface squamous neoplasia (OSSN) and pterygia share risk factors and co-exist in only a minority of cases. Reported rates of OSSN in specimens sent as pterygium for histopathological analysis vary between 0% and nearly 10%, with the highest rates reported in countries with high levels of ultraviolet light exposure. As there is a paucity of data in European populations, the aim of this study was to report the prevalence of co-existent OSSN or other neoplastic disease in clinically suspected pterygium specimens sent to a specialist ophthalmic pathology service in London, United Kingdom. METHODS We performed a retrospective review of sequential histopathology records of patients with excised tissue submitted as suspected "pterygium" between 1997 and 2021. RESULTS In total, 2061 specimens of pterygia were received during the 24-year period, with a prevalence of neoplasia in those specimens of 0.6% (n = 12). On detailed review of the medical records of these patients, half (n = 6) had the pre-operative clinical suspicion of possible OSSN. Of those cases without clinical suspicion pre-operatively, one was diagnosed with invasive squamous cell carcinoma of the conjunctiva. CONCLUSION In this study, rates of unexpected diagnoses are reassuringly low. These results may challenge accepted dogma, and influence future guidance for the indications for submitting non-suspicious pterygia for histopathological analysis.

Abstract
Background Ocular malignancies are uncommon among eye diseases; however, they jeopardize both vision and life. The main objective of this study was to use to describe the epidemiology of eye and ocular adnexa malignancies across different ages and sex. Methods The King Khaled University institutional review board approved this study. Data on ocular cancer were retrieved from the Saudi Cancer Registry between 1994 and 2018. The registry collected important patient information such as demographic information (age, gender, and nationality), clinical details, and tumor classification. Results The total number of cases with ocular cancer diagnosed was 1051 cases. The highest number was recorded in Riyadh (35.39%, n=372), followed by Makkah (16.93%, n=178). The incidence was higher in the 0-4 years' age group (55.21%), and it got down as people got older. The data also revealed differences in the number of reported cases over time, as well as in the representation of eye cancer cases by gender and nationality. While many ocular cancer pathologies were seen, with "Retinoblastoma, not otherwise specified" being the most common (53.32%), the incidence rates for males and females remained largely stable over time. Conclusion The study emphasizes the need for continued monitoring, research, and analysis of potential of epidemiology of ocular cancer occurrence in Saudi Arabia. Identifying the geographical distribution and age pattern of Ocular malignancies have the potential to assist healthcare authorities and policymakers in developing precise strategies to reduce, recognize at an early stage, and successfully manage this condition.

J Natl Cancer Inst 2023; 115:1213-1219. [PMID: 37379162 PMCID: PMC10560597 DOI: 10.1093/jnci/djad119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 06/07/2023] [Accepted: 06/21/2023] [Indexed: 06/30/2023] Open
Abstract
BACKGROUND The main risk factors for squamous cell carcinoma of the conjunctiva (SCCC) are immunodeficiency and exposure to ultraviolet radiation. Little is known about SCCC epidemiology among people with HIV (PWH) in South Africa. METHODS We used data from the South African HIV Cancer Match study, a nation-wide cohort of PWH in South Africa, created through a privacy-preserving probabilistic record linkage of HIV-related laboratory records from the National Health Laboratory Service and cancer records from the National Cancer Registry from 2004 to 2014. We calculated crude incidence rates, analyzed trends using joinpoint models, and estimated hazard ratios for different risk factors using Royston-Parmar flexible parametric survival models. RESULTS Among 5 247 968 PWH, 1059 cases of incident SCCC were diagnosed, for a crude overall SCCC incidence rate of 6.8 per 100 000 person-years. The SCCC incidence rate decreased between 2004 and 2014, with an annual percentage change of ‒10.9% (95% confidence interval: ‒13.3 to ‒8.3). PWH residing within latitudes 30°S to 34°S had a 49% lower SCCC risk than those residing at less than 25°S latitude (adjusted hazard ratio = 0.67; 95% confidence interval: 0.55 to 0.82). Other risk factors for SCCC were lower CD4 counts and middle age. There was no evidence for an association of sex or settlement type with SCCC risk. CONCLUSIONS An increased risk of developing SCCC was associated with lower CD4 counts and residence closer to the equator, indicative of higher ultraviolet radiation exposure. Clinicians and PWH should be educated on known SCCC preventive measures, such as maintaining high CD4 counts and protection from ultraviolet radiation through sunglasses and sunhats when outdoors.

Abstract
Societal factors associated with ocular surface diseases were mapped using a framework to characterize the relationship between the individual, their health and environment. The impact of the COVID-19 pandemic and mitigating factors on ocular surface diseases were considered in a systematic review. Age and sex effects were generally well-characterized for inflammatory, infectious, autoimmune and trauma-related conditions. Sex and gender, through biological, socio-economic, and cultural factors impact the prevalence and severity of disease, access to, and use of, care. Genetic factors, race, smoking and co-morbidities are generally well characterized, with interdependencies with geographical, employment and socioeconomic factors. Living and working conditions include employment, education, water and sanitation, poverty and socioeconomic class. Employment type and hobbies are associated with eye trauma and burns. Regional, global socio-economic, cultural and environmental conditions, include remoteness, geography, seasonality, availability of and access to services. Violence associated with war, acid attacks and domestic violence are associated with traumatic injuries. The impacts of conflict, pandemic and climate are exacerbated by decreased food security, access to health services and workers. Digital technology can impact diseases through physical and mental health effects and access to health information and services. The COVID-19 pandemic and related mitigating strategies are mostly associated with an increased risk of developing new or worsening existing ocular surface diseases. Societal factors impact the type and severity of ocular surface diseases, although there is considerable interdependence between factors. The overlay of the digital environment, natural disasters, conflict and the pandemic have modified access to services in some regions.

Abstract
PURPOSE To describe the risk factors, clinical features, histopathology, treatment, and outcomes of patients with orbital tumour extension of ocular surface squamous neoplasia (OSSN). METHODS Retrospective study of 51 patients with orbital tumour extension (cases) and 360 patients without orbital extension (controls). RESULTS Of 1,653 patients with OSSN, orbital tumour extension was noted in 51 (3%) cases. The risk factors for orbital tumour extension included outdoor occupation (p < 0.03; Odds ratio (OR) = 1.96), Human Immunodeficiency Virus (HIV) infection (p < 0.0001; OR = 5.81), prolonged duration of symptoms (p = 0.01; OR = 1.02), tumour bilaterality (p = 0.02; OR = 2.92), forniceal and tarsal conjunctival involvement, diffuse tumour (p < 0.0001; OR = 9.13), inferior quadrantic location (p < 0.0001; OR = 7.51), increased tumour thickness (p = 0.04; OR = 1.59), higher % of ocular surface involvement (p = 0.002; OR = 1.12), nodular (p = 0.002; OR = 2.61) and nodulo-ulcerative (p < 0.0001; OR = 11.05) tumour morphology, poorly differentiated tumours (p = 0.006; OR = 4.23); invasive squamous cell carcinoma (SCC) (p < 0.0001; OR = 29.76), spindle cell and mucoepidermoid variant (p = 0.02; OR = 16.94) tumours. At a mean follow-up period of 27 months, tumour recurrence in the socket was noted in 1 (2%), locoregional lymph node metastasis (LNM) in 15 (29%) patients, and nine (18%) patients died due to systemic metastasis (SM). T4 tumour at presentation was a risk factor for LNM (p = 0.01; Hazard ratio (HR) = 5.60) and SM (p = 0.0003; HR = 5.09). CONCLUSION Orbital extension of OSSN is rare. Outdoor occupation, HIV infection, larger and thicker tumours in the inferior quadrant with forniceal and/or tarsal conjunctival involvement with nodular or noduloulcerative morphology, poor tumour differentiation, SCC, spindle cell and mucoepidermoid variants on histopathology are at increased risk for orbital tumour extension.

Abstract
South Africa's HIV epidemic has evolved over time in terms of numbers of people living with HIV, access to antiretroviral treatment (ART) and age. These changes have profoundly influenced local cancer patterns. The Johannesburg Cancer Study has, over a period of 22 years (1995-2016), recruited over 20 000 incident black cancer patients who consented to provide answers to a questionnaire and blood samples (serum, DNA). This has presented a unique opportunity to examine the evolving association of HIV with cancer in Africa. We used logistic regression models to explore case-control associations between specific cancers and HIV, using participants with non-infection related cancers as controls. Using data of 20 835 cancer patients with confirmed HIV status, we found the following cancers to be associated with HIV: Kaposi's sarcoma (ORadj ; 95%CI): (99.1;72.6-135.1), non-Hodgkin lymphoma (11.3;9.3-13.6), cervical cancer (2.7;2.4-3.0), Hodgkin lymphoma (3.1;2.4-4.2), cancer of the eye/conjunctiva (18.7;10.1-34.7), anogenital cancers (anus [2.1;1.4-3.2], penis [5.4;2.7-10.5], vulva [4.8;3.5-6.4], vagina [5.5;3.0-10.2]), oropharyngeal cancer (1.6;1.3-1.9), squamous cell carcinoma of the skin (3.5;2.4-4.9), melanoma (2.0;1.2-3.5) and cancer of the larynx (1.7;1.3-2.4). Kaposi's sarcoma odds ratios increased from the pre-ART (1995-2004) to the early ART (2005-2009) period but declined in the late ART (2010-2016) period. Odds ratios for cancers of the eye/conjunctiva, cervix, penis and vulva continued to increase in recent ART periods. Our study confirms the spectrum of HIV-associated cancers found in other African settings. The odds ratios of conjunctival and HPV-related cancers continue to rise in the ART era as the HIV positive population ages.

Abstract
Background Non-cutaneous squamous cell carcinoma (ncSCC) of the orbital region is very rare. Thus, its epidemiological characteristics and prognosis are poorly understood. The aim of the study was to assess the epidemiological characteristics and survival outcomes of ncSCC of the orbital region. Methods Incidence and demographic data on ncSCC of the orbital region were extracted from the Surveillance, Epidemiology, and End Results (SEER) database and analyzed. The chi-square test was used to calculate the differences between groups. Univariate and multivariate Cox regression analyses were performed to determine the independent prognostic factors for disease-specific survival (DSS) and overall survival (OS). Results The overall incidence of ncSCC in the orbital region from 1975 to 2019 was 0.68/1,000,000, and the incidence showed an increasing trend during this period. A total of 1,265 patients with ncSCC of the orbital region (mean age, 65.3 years) were identified in the SEER database. Of these, 65.1% were aged ≥60 years, 87.4% were White, and 73.5% were male. The conjunctiva (74.5%) was the most common primary site, followed by the orbit (12.1%), lacrimal apparatus (10.8%), and overlapping lesion of the eye and adnexa (2.7%). Multivariate Cox regression analysis revealed that age, primary site, SEER summary stage, and surgery were independent prognostic factors for DSS, whereas age, sex, marital status, primary site, SEER summary stage, and surgery were independent prognostic factors for OS. Conclusions The incidence of ncSCC in the orbital region has increased over the past 40 years. It usually affects White people, men, and people aged ≥60 years, and its most common site is the conjunctiva. Orbital SCC has worse survival outcomes than SCC of other sites in the orbital region. Surgery is the independent protective treatment for ncSCC of the orbital region.

Abstract
The rise of primary topical monotherapy with chemotherapeutic drugs and immunomodulatory agents represents an increasing recognition of the medical management of ocular surface squamous neoplasia (OSSN), which may replace surgery as the standard of care in the future. Currently, there is no consensus regarding the best way to manage OSSN with no existing guidelines to date. This paper seeks to evaluate evidence surrounding available treatment modalities and proposes an approach to management. The approach will guide ophthalmologists in selecting the most appropriate treatment regime based on patient and disease factors to minimize treatment related morbidity and improve OSSN control. Further work can be done to validate this algorithm and to develop formal guidelines to direct the management of OSSN.

Abstract
A male patient in his 70s presented with left eye necrotising scleritis. His ocular history was significant for pterygium excision with mitomycin C 3 months prior in the affected eye, open-angle glaucoma, nuclear sclerosis cataract and previous sixth cranial nerve palsy. Scleral culture was negative and blood work was positive for rheumatoid factor and HLA-B27. The patient was treated for necrotising scleritis with oral doxycycline, vitamin C, ranitidine and prednisone with gradual taper over 45 days. Two months after initiating treatment, his necrotising scleritis achieved complete resolution; however, a new-onset ocular surface squamous neoplasia (OSSN) was identified at the temporal limbus of the contralateral eye. He was treated with topical interferon alpha-2b 1 million IU qid and achieved complete resolution after 4 months. The case highlights both the acute precipitation of OSSN following oral steroids and a sight-threatening complication following pterygium excision.

Abstract
BACKGROUND/AIMS To review the clinicopathological features of caruncle biopsies carried out at a district general hospital in the United Kingdom (UK), and compare with other centres where data has been published. METHODS Retrospective, single-centre, observational case series between 2004-2020. RESULTS A total of 31 lesions from 31 patients were analysed. 18 of 31 patients were men (58%), and the age ranged from 12 to 91 years. 13 different histopathological types of lesions were identified in our case series, including 9 melanocytic nevi (29%), 7 benign squamous papillomas (23%), 5 skin adnexal lesions (16%), 3 chronic inflammation (10%), 3 epithelial cysts (10%), 1 basal cell carcinoma (3%), 2 malignant melanomas (6%) and l lymphoproliferative disorder (3%). Pre-operative suspected diagnoses were often vague but correct in 12 of 18 cases (67%), where data was available. CONCLUSION The uncommon nature and variety of caruncular lesions make the diagnostic process difficult. Our case series is the first reported in the UK, showing a slightly higher proportion of malignant melanomas, in keeping with the population demographics. Excisional biopsies would, therefore, be prudent in the majority of cases to rule out any possible malignancy.

Abstract
Objective Exploring the risk factors of conjunctival squamous cell carcinoma (CSCC) and establishing a prognostic model. Methods Information on patients with CSCC was extracted from the SEER database, conducting a retrospective study. 650 patients with CSCC were finally included in the model. Descriptive analysis was performed by Chi-square test and T-test. The risk factors of CSCC were explored by COX multivariate analysis, and the corresponding prognostic model was established as a result. Results The all-cause mortality rate of CSCC was 38.3%, and the risk factors were age (HR = 1.077), sex (HR = 0.691), grade (HR = 7.857), laterality (HR = 1.403), N (HR = 7.195), M (HR = 0.217), and surgery (HR = 1.618), all P < 0.05. The new model had C index and area under curve ROC (AUC) value greater than 0.7. Calibration curve, Net Reclassification Index (NRI), Integrated Discrimination Improvement (IDI), and Decision Curve Analysis (DCA) indicate the new model has better predictive performance than the American Joint Committee on Cancer (AJCC-TNM). Conclusions Compared with the clinical guidance of AJCC (TNM) for patients with CSCC, the established model exhibits good performance and can provide guidance for clinical decision-making.

Abstract
This case reports a rare case of conjunctival squamous cell carcinoma in China. The elderly (86-year-old) female patient was diagnosed and treated effectively after three times of diagnosis. During this period, she was misdiagnosed and ineffective treatment for many times. Therefore, we propose to make an integrated diagnosis based on histopathological diagnosis, combined with a variety of diagnostic methods including MRI and CDFI, supplemented by updated multiple immunohistochemically techniques, so as to achieve the purpose of accurate diagnosis.

Abstract
Human papillomaviruses (HPV) are involved in approximately 5% of solid cancers worldwide. The mucosotropic genotypes infect the stratified epithelium of various locations, where persistent infection may lead to invasive carcinomas. While the causative role of HPV in certain anogenital and head and neck carcinomas is well established, the role of HPV in carcinomas arising in the mucosal membranes of the ocular adnexal tissue (the lacrimal drainage system and the conjunctiva) has been a topic of great uncertainty. Therefore, we conducted a series of studies to assess the correlation between HPV and carcinomas arising in the mucosa of the ocular adnexal tissue and characterize the clinical, histopathological, and genomic features of the tumors in the context of HPV status in a Danish nationwide cohort. We collected clinical and histopathological data and tumor specimens from patients with carcinomas of the conjunctiva and the lacrimal drainage system, and their potential precursors, identified in Danish nationwide registries. The HPV status of the tumors was determined by the combined use of HPV DNA polymerase chain reaction (PCR), HPV E6/E7 mRNA in-situ hybridization, and p16 immunohistochemistry. The genomic profile was investigated by high-throughput DNA sequencing targeting 523 cancer-relevant genes. The literature to date on carcinomas of the lacrimal drainage system and the conjunctiva was summarized. In the Danish cohort, 67% of all carcinomas of the lacrimal drainage system and 21% of all conjunctival carcinomas were HPV-positive. HPV16 was the most frequently implicated genotype. A full-thickness expression of the viral oncogenes E6 and E7 was evident in almost all HPV DNA-positive cases. The HPV-positive carcinomas of the conjunctiva and the lacrimal drainage system shared histopathological and genomic features distinct from their HPV-negative counterparts. The HPV-positive carcinomas were characterized by a non-keratinizing morphology, p16 overexpression, high transcriptional activity of HPV E6/E7, and frequent pathogenic variants in the PI3K-AKT signaling cascade. In contrast, the HPV-negative carcinomas were characterized by a keratinizing morphology, lack of p16 and E6/E7 expression, and frequent somatic pathogenic variants in TP53, CDKN2A, and RB1. Among the patients with conjunctival tumors, HPV positivity was associated with a younger age at diagnosis and a higher risk of recurrence. In conclusion, the results support an etiological role of HPV in a subset of conjunctival and LDS carcinomas and their precursor lesions. Our investigations have shown that the HPV-positive carcinomas of the ocular adnexa share genomic and phenotypic characteristics with HPV-positive carcinomas of other anatomical locations. Therefore, these patients may be eligible for inclusion in future basket trials and future treatment regimens tailored to the more frequently occurring HPV-positive carcinomas of other locations. Future research will further elucidate the diagnostic, prognostic, and predictive role of HPV in these carcinomas.

Abstract
Purpose: To report a case of combination therapy with interferon β1b (IFN-β1b) and mitomycin-C (MMC) for recurrent ocular surface squamous neoplasia (OSSN).Case summary: A 72-year-old female presented with a white mass at the medial conjunctiva of the right eye. A gelatinous, nodular white lesion was observed near the medial limbus of the right eye. On histological examination, it was diagnosed as squamous cell carcinoma in situ. A white nodule was found at the resection site 1 year after the resection. IFN-β1b (1 mIU/mL) and 0.02% MMC were administered daily with a diagnosis of recurrent OSSN. IFN-β1b was instilled four times a day for 1 month, while MMC was instilled four times a day for 4 weeks. After 1 month of the combination treatment, the lesion disappeared. MMC was stopped, while IFN-β1b was reduced to twice daily instillation, maintained for 1 month, and then stopped. On examination 12 months after discontinuation of the combination treatment, there were no recurrences or drug-related complications.Conclusions: Combination therapy with IFN-β1b and MMC for recurrent OSSN after surgical resection was relatively safe with no major complications.

Abstract
Ocular surface squamous neoplasia (OSSN) has a high incidence in the southern hemisphere. This prospective study evaluated the incidence of OSSN in the Waikato region of New Zealand. All patients presenting with pterygium or conjunctival lesions in the Waikato region in 2020 were included. All surgeons in the region were asked to send all conjunctival and corneal specimens excised for histopathologic examination. The primary outcome measure was the incidence of OSSN. Eighty-eight percent of all excised specimens were sent for histopathologic examination. Of the 185 excised lesions sent for histopathological assessment, 18 (10%) were reported as OSSN. Patients were on average 69.4 years of age (standard deviation, SD = 6.9), predominantly male (78%), and of New Zealand-European ethnicity (89%). The OSSN annual incidence was 3.67/100,000/year. Histology grades included conjunctival intraepithelial neoplasia (CIN)-I (25%), CIN-II (25%), CIN-III (12.5%), carcinoma in situ (25%), and invasive squamous cell carcinoma (SCC) (12.5%). One patient with invasive SCC required exenteration. This study identified a high incidence rate of OSSN and is the first prospective study to analyze OSSN epidemiology in New Zealand.

Abstract
BACKGROUND Ocular surface squamous neoplasia (OSSN) is a heterogeneous group of proliferative squamous lesions on the ocular surface with varying biologic behaviours. This study aims to report the clinical profile and pathological characteristics of cases of OSSN seen at a tertiary referral centre in North West Nigeria. METHODS A retrospective review of all cases of OSSN diagnosed over a 10-year period was done. RESULTS OSSN accounted for 68 out of 91 ocular surface lesions affecting twice as many males as females and a peak incidence in the 30-39 years age group. They frequently presented as higher-grade and higher-stage lesions with invasive squamous cell carcinoma being the most frequently diagnosed OSSN. They also frequently showed an association with HIV infection and a relatively long duration of symptoms before presentation. CONCLUSION OSSN occurs in a relatively young age group in our environment. Certain clinical and epidemiological features appear to predict the occurrence of higher-grade lesions, and this may help in the clinical prediction of likely pathologic grade and/or biologic behaviour of these lesions.

Abstract
In-situ hybridization provides a convenient and reliable method to detect human papillomavirus (HPV) infection in formalin-fixed paraffin-embedded tissue. Cases of conjunctival papillomas, conjunctival intraepithelial neoplasia (CIN), conjunctival carcinoma in situ (cCIS), and invasive squamous cell carcinoma (SCC), in which low-risk (LR) and/or high-risk (HR) HPV types were evaluated by RNA or DNA in-situ hybridization, were retrospectively identified. LR HPV types were frequently detected in conjunctival papillomas (25/30, 83%), including 17/18 (94%) with RNA probes, compared to 8/12 (75%) with DNA probes. None of the CIN/cCIS or SCC cases were positive for LR HPV by either method. HR HPV was detected by RNA in-situ hybridization in 1/16 (6%) of CIN/cCIS cases and 2/4 (50%) of SCC cases, while DNA in-situ hybridization failed to detect HPV infection in any of the CIN/cCIS lesions. Reactive atypia and dysplasia observed in papillomas was generally associated with the detection of LR HPV types. Collectively, our findings indicate RNA in-situ hybridization may provide a high-sensitivity approach for identifying HPV infection in squamous lesions of the conjunctiva and facilitate the distinction between reactive atypia and true dysplasia. There was no clear association between HPV infection and atopy in papillomas or dysplastic lesions.

Abstract
BackgroundThe etiopathogenesis of ocular surface squamous neoplasia (OSSN) is not fully understood. We assessed the frequency of oncogenic viruses in OSSN by immunohistochemistry (IHC) and polymerase chain reaction (PCR) for human papillomavirus (HPV), Epstein–Barr virus (EBV), Merkel cell polyomavirus (MCPyV), Kaposi sarcoma virus, and adenovirus. Cases from Zambia were prospectively enrolled using a cross-sectional study design between November 2017 and March 2020.MethodsDemographic and clinical data [age, sex, HIV status, antiretroviral therapy (ART) history, CD4 count, plasma viral load] and tumor biopsies were collected from 243 consenting patients. Tumor samples were bisected, and half was used for DNA isolation, while the other half was formalin fixed and paraffin embedded (FFPE) for histopathology analysis. The expressions of latent EBV nuclear antigen 1 (EBNA1), CDKN2A/p16INK4A (p16), and MCPyV large T-antigen (LT) were tested by IHC. Multiplex PCR was used to detect 16 HPV genotypes and four other DNA tumor viruses [Kaposi’s sarcoma-associated herpesvirus (KSHV), EBV, MCPyV, and adenovirus]. Relationships between HIV status, viral DNA and protein expression, and tumor grades were determined by statistical analysis.ResultsOSSN tumors from patients were 29.6% preinvasive and 70.4% invasive. Patients presented with unilateral tumors that were 70.4% late stage (T3/T4). OSSN patients were HIV positive (72.8%). IHC on 243 FFPE biopsies resulted in the detection of EBNA1 (EBV), p16 high-risk HPV (HR-HPV), and MCPyV LT expression in 89.0%, 4.9%, and 0.0%, respectively. EBNA1 was expressed in all grades of preinvasive [cornea–conjunctiva intraepithelial neoplasia (CIN)1, 100%; CIN2, 85.7%; CIN3, 95.8%; and carcinoma in situ (CIS), 83.8%] and in invasive (89.2%) OSSN. PCR on 178 samples detected EBV, HR-HPV, and MCPyV in 80.3%, 9.0%, and 13.5% of tumors, respectively. EBV was detected in all grades of preinvasive and invasive OSSN. EBV detection was associated with high HIV viral loads (p = 0.022). HR-HPV was detected in 0.0% CIN1, 0.0% CIN2, 5.6% CIN3, 13.0% CIS, and 7.0% invasive OSSN.ConclusionsOur findings of EBV DNA and EBNA1 protein in all the grades of preinvasive and especially invasive OSSN are consistent with a potential causal role for EBV in OSSN. A role of HPV in OSSN was not clearly established in this study.

Abstract
Purpose
To evaluate clinical characteristics, treatments, and outcomes in patients with ocular surface squamous neoplasia (OSSN) at a tertiary center in Northern Thailand.
Methods
Patients diagnosed with either corneal-conjunctival intraepithelial neoplasia (CIN) or squamous cell carcinoma (SCC) from May 2000 to December 2015, were recruited. The patients’ demographics, symptoms, clinical characteristics, cytopathology, treatments, and outcomes were reviewed.
Results
Overall 171 eyes from 168 patients, 92 eyes were CIN and 79 eyes were SCC. Males were affected in 65.5%. The mean age was 58.8 ± 16.8 (29–99) years. In most cases (60.3%), the tumors were located at the limbus. The most common clinical characteristic was papilliform appearance (46.2%). Human immunodeficiency virus (HIV) infection was found in 37 (22.0%) patients with a mean age of 40.5 ± 7.7 years. The treatments and outcomes were evaluated in 136 eyes whose main initial treatment was wide excision with adjunctive cryotherapy (47.8%), followed by topical mitomycin C (30.9%). The mean follow-up time after treatment was 20.8 ± 2.2 (3–110) months and the recurrence occurred in 18 eyes (13.2%) during the follow-up period. The mean recurrence-free time (months) for CIN was significantly longer than that of SCC (81.3 ± 10.0 [95%CI 61.5 – 101.1] vs 33.2 ± 4.6 [95%CI 24.0 – 42.3], p = 0.030). SCC was the only significant risk factor that influences the recurrence of the tumors with the adjusted hazard ratio of 5.69 (p = 0.005).
Conclusion
OSSN in Northern Thailand usually involved a limbal area and presented as a papilliform mass. HIV infection should be suspected in young patients. CIN had better outcomes after treatments than invasive SCC.

Abstract
Purpose This report describes a recurrent case of ocular surface squamous neoplasia in a middle-aged and immunocompetent patient. Observations The summary of clinical presentation, workup, and medical and surgical intervention are described, followed by a brief overview of the treatment challenges associated with superiorly located conjunctival lesions. Conclusions In cases where topical chemotherapeutic drops cannot penetrate the lesion, the location of conjunctival lesions can sometimes pose a challenge. Hence, injections in such cases might be preferred. However, histopathology still plays a significant role in achieving a definitive diagnosis.

Abstract
Background Conjunctival lesions are common with a wide spectrum of benign, premalignant, and malignant lesions. Few histopathological studies have been conducted on conjunctival lesions with variable designs and results. Our aim in this study is to provide information on common conjunctival lesions seen in an ophthalmology tertiary care center in Saudi Arabia. Methods A retrospective, observational study of all consecutive conjunctival tissue specimens sent for histopathological assessment to the pathology department from 2015 to 2019 were analyzed. Clinical data were collected from medical records, and the histopathological slides were reviewed by a single pathologist. Results A total of 110 conjunctival specimens from 108 patients were included (mean age: 53 years, 67 males and 43 females). Bilateral involvement was mostly found in inflammatory lesions (40%). Most lesions were benign (91%), with a significantly longer duration of symptoms in malignant lesions (p = 0.036*). The clinical diagnosis matched the final histopathological diagnosis in 75.5% of the total specimens. The most frequent category of benign lesions was fibrodegenerative and proliferative lesions (53.6%), with a significantly higher prevalence among adult males (p < 0.001). Melanocytic lesions were more common in children (33.3%) than adults (9.8%), and the mean age of children was significantly lower (p = 0.013). The most frequent malignant lesion was ocular surface squamous neoplasia (50%), with equal prevalence among males and females. The overall outcome was favorable in 89.4% and unfavorable in 10.6%, mostly due to surgical complications, further progression of the lesion, or recurrence. Conclusion This study shows variability in the frequency of conjunctival lesions based on gender, age, geographical, racial, and environmental factors. There has been a shift in the gender-based prevalence of ocular squamous neoplasia over the last three decades, probably due to a change in lifestyle.

Abstract
Purpose of review To review and update the latest findings in diagnosis and management of ocular surface squamous neoplasia (OSSN). Recent findings OSSN is the most common anterior segment neoplastic disease process. Several ocular surface imaging techniques have been developed for the early diagnosis and management of clinical and subclinical ocular surface squamous neoplasia, including high-resolution optical coherence tomography (HR-OCT), in vivo confocal microscopy, and ultrasound biomicroscopy. Treatment modalities include both surgical and medical management, with a recent trend towards primary and adjunctive pharmacotherapy. Summary There is increasing use of HR-OCT for the diagnosis and monitoring of clinical and subclinical OSSN lesions. Topical pharmacotherapy agents, including interferon α-2b, 5-fluorouracil, and mitomycin C, have demonstrable efficacy in the treatment of OSSN and their use may be dictated based upon tumor factors, patient factors, cost, and side effect profile. Both surgical excision and adjunctive topical medications have excellent success, with the favored treatment method trending towards topical pharmacotherapy as primary therapy.

Abstract
PURPOSE To explore clinical features and outcomes of ocular surface squamous neoplasia (OSSN) treated with primary interferon (IFN)-α2b, based on patient cigarette smoking status. METHODS Retrospective nonrandomized, interventional cohort study on 212 consecutive tumors in 194 patients, all of whom were treated with topical and/or injection IFNα2b. RESULTS There were 88 tumors in 76 patients with current or past smoking history (smokers) and 124 tumors in 118 nonsmoking patients (nonsmokers). A comparison (smokers vs. nonsmokers) revealed smokers with more frequent bilateral disease (16% vs. 3%, P = 0.003), more frequent involvement of inferior forniceal (34% vs. 21%, P = 0.03) and inferior tarsal conjunctiva (38% vs. 24%, P = 0.04), greater mean number of clock hour involvement (4.1 vs. 3.5 clock hours, P = 0.04), and greater dome growth pattern (30% vs. 15%, P = 0.01). There was no difference regarding method of IFNα2b administration as topical (61% vs. 71%, P = 0.14), injection (10% vs. 6%, P = 0.32), or combination topical/injection (28% vs. 23%, P = 0.33). A comparison revealed smokers with more frequent recurrence after initial response (23% vs. 13%, P = 0.04). There was no difference regarding initial tumor response or time to response, treatment side effects, or systemic outcomes. CONCLUSIONS Regarding ocular surface squamous neoplasia, smokers more often display bilateral, dome-shaped tumors with inferior forniceal or tarsal involvement, and greater extent than nonsmokers. After treatment with topical and/or injection IFNα2b, control is equivalent, but smokers show greater recurrence.

Abstract
Purpose The genomic alterations contributing to the pathogenesis of conjunctival squamous cell carcinomas (SCCs) and their precursor lesions are poorly understood and hamper our ability to develop molecular therapies to reduce the recurrence rates and treatment-related morbidities of this disease. We aimed to characterize the somatic DNA alterations in human papillomavirus (HPV)-positive and HPV-negative conjunctival SCC. Methods Patients diagnosed with conjunctival SCC in situ or SCC treated in ocular oncology referral centers in Denmark were included. HPV detection (HPV DNA PCR, p16 immunohistochemistry, and mRNA in situ hybridization) and targeted capture-based next-generation sequencing of 523 genes frequently involved in cancer were performed to describe the mutational profile based on HPV status. Results Tumor tissue was available in 33 cases (n = 8 conjunctival SCCs in situ, n = 25 conjunctival SCCs), constituting 25 male and 8 female patients. Nine cases were HPV positive. The HPV-positive SCCs in situ and SCCs were characterized by transcriptionally active high-risk HPV (types 16 and 39) within the tumor cells, frequent mutations in PIK3CA (n = 5/9), and wild-type TP53, CDKN2A, and RB1, while the HPV-negative counterparts harbored frequent mutations in TP53 (n = 21/24), CDKN2A (n = 7/24), and RB1 (n = 6/24). Conclusions Our findings have delineated two potentially distinct distributions of somatic mutations in conjunctival SCC based on HPV status-pointing to different biological mechanisms of carcinogenesis. The present findings support a causal role of HPV in a subset of conjunctival SCC.

Abstract
CLINICAL RELEVANCE This study investigates the demographic and clinical features of conjunctival tumours. BACKGROUND Conjunctival tumours include a large spectrum of conditions ranging from benign lesions to aggressive, life-threatening malignancies. Knowing the distribution of conjunctival tumours by age and gender is important for reducing cancer morbidity. METHODS The clinical records of 375 patients (410 eyes) diagnosed with a conjunctival mass at a tertiary referral centre between February 1999 and November 2020 were retrospectively evaluated. RESULTS Two-hundred-seventeen (57.9%) patients were male and 158 (42.1%) were female. Of 410 conjunctival tumours, 159 (38.8%) were benign, 106 (25.9%) premalignant, and 145 (35.4%) malignant. Overall, the 3 most common diagnoses were squamous cell carcinoma (SCC, 19.5%), conjunctival intraepithelial neoplasia (CIN, 18.3%), and naevus (17.8%). The most common benign, premalignant, and malignant tumours were naevus (n = 73/159, 45.9%), CIN (n = 75/106, 70.8%), and SCC (n = 80/145, 55.2%) respectively. Naevus was the most common tumour in ≤20 years and > 20-40 years old patient groups (56.2% and 25.4% respectively). CIN was the most frequent tumour in patients aged > 40-60 years (25.7%). SCC was the most common tumour in > 60-80 years and > 80 years old patient groups (44.3% and 80.0% respectively). The median patient age was greater in patients with malignant tumours (64.5 years) compared to patients with premalignant (55.5 years, p = 0.011) and benign tumours (22.0 years, p < 0.001). Malignant tumours displayed larger base diameter, greater thickness, and intrinsic vessels compared to premalignant or benign lesions (p < 0.001 for each parameter). Malignant tumours also displayed more amelanotic vs melanotic appearance (p < 0.001) and limbal vs extralimbal bulbar location compared to benign lesions (p < 0.001). CONCLUSION Premalignant and malignant tumours comprised 61.2% of all conjunctival tumours and were usually detected in patients > 40 years of age in this study.

Abstract
PURPOSE To study the efficacy of interferon alfa-2b (IFN-a2b) on pigmented ocular surface squamous neoplasia (p-OSSN) and assess the resolution of the pigment to the treatment. METHODS A retrospective case series of 8 tumors in 7 patients. RESULTS The mean age at diagnosis of p-OSSN was 65 years (median, 61 years; range, 51-84 years), and all patients were men. The mean duration of symptoms was 2 months (median, 1 month; range, 1-4 months). One patient had 2 distinct lesions in the same eye. Tumor epicenter was located at the limbus (n = 5) or bulbar conjunctiva (n = 2). Complexion-associated melanosis was noted in all eyes. The mean basal dimension of the tumor was 8 mm (median, 7 mm; range, 5-12 mm). The mean % of tumor pigmentation was 47% (median, 30%; range, 10%-100%). The treatment details included topical IFN-a2b (n = 1) or a combination of topical and subconjunctival injection of IFN-a2b (n = 7). All patients with p-OSSN showed excellent response to IFN-a2b with complete tumor regression and resolution of tumor-associated pigment with a mean number of 2 subconjunctival IFN-a2b injections (median, 2; range, 0-3) and topical IFN-a2b for an average of 2 months (median, 2 months; range, 1-3 months). There was no change in the complexion-associated melanosis with IFN-a2b. CONCLUSIONS IFN-a2b is very effective in the management of p-OSSN. There is a complete resolution of the pigment along with the tumor.

Abstract
Human papillomaviruses (HPV) are a large group of DNA viruses that infect the basal cells of the stratified epithelium at different anatomic locations. In the ocular adnexal region, the mucosa of the conjunctiva and the lacrimal drainage system, as well as the eyelid skin, are potential locations for HPV-related neoplasia. The role of HPV in squamous cell neoplasia of the ocular adnexa has been debated for several decades. Due to the rarity of all these tumors, large studies are not available in the scientific literature, thereby hampering the precision of the HPV prevalence estimates and the ability to conclude. Nevertheless, increasing evidence supports that defined subsets of conjunctival papillomas, intraepithelial neoplasia, and carcinomas develop in an HPV-dependent pathway. The role of HPV in squamous cell tumors arising in the lacrimal drainage system and the eyelid is still uncertain. Further, the potential of HPV status as a diagnostic, prognostic, or predictive biomarker in these diseases is a topic for future research.

Abstract
PURPOSE We aimed to study the prevalence of human papillomavirus (HPV) in conjunctival intraepithelial neoplasia and carcinoma. Furthermore, we aimed to explore whether geographical differences or different detection modalities are associated with the conflicting information regarding HPV and the development of the disease. METHODS We searched the MEDLINE, EMBASE and Scopus databases for studies reporting on HPV and conjunctival intraepithelial neoplasia or carcinoma. The pooled prevalence proportions, odds ratio (OR) and corresponding 95% confidence intervals were calculated assuming a random-effects model. Subgroup analyses and meta-regression explored possible sources of heterogeneity. RESULTS A total of 39 studies were included in the systematic review. The pooled prevalence of HPV in conjunctival intraepithelial neoplasia and carcinoma was 26%, with HPV16, 18, and 33 being the most frequently reported genotypes. Human papillomavirus (HPV) infection was associated with an increased risk of conjunctival intraepithelial neoplasia and carcinoma (OR 8.4, 95% confidence interval (CI) 3.7-19.1); lower in studies from African countries (OR 1.7, 95% CI 0.9-3.5) than other countries (OR 16.1, 95% CI 5.8-44.3), p = 0.013. CONCLUSION Human papillomavirus infection increases the odds of conjunctival intraepithelial neoplasia and carcinoma by 8.4 compared to healthy conjunctival mucosa or other ocular surface diseases. There seem to be geographical differences regarding HPV in conjunctival intraepithelial neoplasia and carcinoma. HPV16 was the most prevalent genotype, followed by HPV18 and HPV33, meaning that most of the HPV-related conjunctival intraepithelial neoplasia and carcinoma may be prevented by the HPV vaccines that are currently available.

Abstract
BACKGROUND Ocular surface squamous neoplasia (OSSN) is a relatively rare disease with a low mortality and highly variable incidence. Despite a high incidence of OSSN in the Southern hemisphere, there is limited epidemiological data for New Zealand. The current study aims to assess the incidence, demographics, and histological grade of OSSN in the Waikato region of New Zealand, home to ~10% of the population of New Zealand. METHODS Non-interventional retrospective cohort study. All conjunctival biopsy histology reports from 2010 to 2019 in the Waikato region of New Zealand were analysed. Age, sex, and ethnicity were analysed and the incidence of OSSN was calculated. Main outcome measures included histological grade, rate of recurrence, and incidence of OSSN. RESULTS A total of 386 patients underwent conjunctival biopsy with histology during the study period. Eighty-three lesions (22%) involving 80 patients (21%) were reported positive for OSSN. Patients with OSSN had a mean age of 68.9 years (SD = 13.2), were predominantly male (76%), and of New Zealand-European ethnicity (53%). Conjunctival intraepithelial neoplasia-1 (30%) was the most frequent diagnosis. Three patients (4%) had recurrent lesions requiring repeat biopsy. The peak annual OSSN incidence rate was 3.81/100,000 population in 2019. The overall ten-year incidence was 2.13/100,000 population/year. CONCLUSION This is the largest study to investigate OSSN incidence in New Zealand. The incidence rate of OSSN is one of the highest rates reported in the literature.

Abstract
Corneal involvement in HIV-infected individuals may be broadly classified into two categories, namely, infectious and noninfectious with the vast majority of manifestations occurring in the former. In this article, we shall focus on these two categories and strive to highlight those presentations that should alert the clinician to suspect underlying HIV infection. Infectious group mainly consists of Herpitic group of viral infections. Bacterial causes may be due to Staphylococcus epidermidis, Staphylococcus aureus, Pseudomonas aeroginosa, alpha hemolytic Streptococcus, Micrococcus and Bacillus. Fungalf keratitis in HIV-infected individuals depends on the geographic locations from which patient comes. Microsporidia and Acanthamoeba are common Protozoal causes. Non-infective inflammatory causes include peripheral ulcerative keratitis, keratoconjunctivitis sicca, and squamous cell carcinoma of the conjunctiva. Severity which is abnormally severe or very minimally reactive makes the clinician suspect of immunosuppression.

Abstract
BACKGROUND Ocular surface squamous neoplasia (OSSN) is a low-grade malignancy arising from the squamous epithelium of the ocular surface AIM: To describe the clinical presentation, histological diagnoses, treatment, and outcome of treatment in patients with OSSN managed at a tertiary health facility. METHODS Medical records of all patients with OSSN managed using a standardized treatment protocol over a 10-year period were reviewed. RESULTS Eighty-six patients comprising 44 (51.2%) males and mean age of 48.2 ± 15.8 years were studied. The most common presentation was a fleshy growth in the eye in all patients, and 43 (50.0%) patients tested positive to human immunodeficiency virus. The right eye was affected in 44 (51.2%) patients with no bilateral tumors, and the medial limbus was involved in 28 (32.6%) patients. Morphologically, 40 (46.5%) patients had gelatinous growth, 24 (27.9%) patients were in Tis category while 30 (34.9%) patients were in T4 category. Twenty-eight (32.6%) patients received complete course of adjuvant topical mitomycin C (0.04%) while nine (10.5%) patients completed adjuvant systemic chemotherapy and external beam radiation. Overall, 61 (70.9%) patients had no tumor recurrence, seven (8.1%) patients had recurrent tumor, while the status of 18 (20.9%) patients was not known. CONCLUSION OSSN occurs more commonly in younger age group in our studied population and is strongly associated with HIV seropositivity. Intraoperative cryotherapy in patients with carcinoma in situ and intraoperative cryotherapy with adjuvant topical mitomycin C in those with invasive SCC that is limited to the ocular surface are associated with low tumor recurrence.

Abstract
Purpose: To describe the clinical features and management of post-keratoplasty ocular surface squamous neoplasia (pk-OSSN) in patients with xeroderma pigmentosum (XP).Methods: Retrospective case series of seven patients with XP.Results: The mean age at diagnosis of pk-OSSN was 22 years (median, 21 years; range, 12 to 37 years). There were four males and three females. Full-thickness keratoplasty (n = 5) and Descemet stripping endothelial keratoplasty (n = 2) were performed for optical (n = 6) and therapeutic indications (n = 1). None of the patients had evidence of OSSN before or at the time of keratoplasty. The mean interval between keratoplasty and pk-OSSN was 44 months (median, 14 months; range, 3 to 109 months). The tumor epicenter was located at the limbus (n = 4), bulbar conjunctiva (n = 1) or cornea (n = 2). The mean dimension of the lesions was 12 mm (median, 11 mm; range, 6 to 18 mm). Treatment details included conjunctival/corneal tumor excision (n = 6), plaque brachytherapy (n = 3; 1 primary, 2 adjuvant) and extended enucleation (n = 1). One patient had tumor recurrence 18 months after OSSN treatment, which was treated with wide excisional biopsy. All patients are alive and free of disease over a mean follow-up period of 37 months (median, 37 months; range, 4 to 65 months).Conclusion: XP patients undergoing keratoplasty can develop OSSN several months to years after keratoplasty and require close follow-up for the same. Wide excisional biopsy with/without plaque radiotherapy is effective in the management of pk-OSSN.

Abstract
PURPOSE Information regarding risk of metastasis and disease-related death (DD) from conjunctival squamous cell carcinoma (SCC) is relatively scarce. We explored prognostic factors for orbital exenteration, local recurrence, nodal metastasis, and DD in patients with conjunctival SCC. DESIGN Retrospective cross-sectional study. METHODS All consecutive patients with conjunctival SCC treated by the senior author at MD Anderson Cancer Center during1999-2018 were included. Survival curves were estimated using the Kaplan-Meier method, and survival differences were assessed using 2-sided log-rank tests. RESULTS The study included 44 patients (24 men, 20 women); median age was 64 years (range, 40-90). T categories at presentation were as follows: Tis, 20 patients; T2, 8; T3, 9; and T4, 7. Eighteen patients (41%) had tumors exclusively in the bulbar conjunctiva; 26(59%) had nonbulbar conjunctival involvement. The median follow-up time was 29.2 months (95% CI: 21.8-44.3). Orbital exenteration was performed in 10 cases (23%) and was associated with T3 or more advanced disease at presentation (p < 0.001). Seven patients developed local recurrence during follow up. History of organ transplant correlated with local recurrence and orbital exenteration (p < 0.01). Nodal metastasis was present in 1 patient at presentation and occurred in 3 patients during follow up, for an overall nodal metastasis rate of 9% (4/44). By end of follow up, 2 patients had died of disease, 4 had died of other causes, and 38 were alive with no evidence of disease. The results suggest that both orbital exenteration and nodal metastasis are independent variables associated with DD. CONCLUSIONS In patients with conjunctival SCC, orbital exenteration and nodal metastasis are associated with DD and organ transplantation is associated with orbital exenteration.

Abstract
AIM This study aimed to characterize the clinical and pathologic presentation of ocular surface tumors (OSTs) and to more precisely differentiate the grades of ocular surface squamous neoplasia (OSSN) and benign lesions among Zambians. METHODS Two-hundred sixty-five Zambian patients presenting with ocular surface growths, suspicious for OSSN, were recruited between November 2017 and November 2019 to a cross-sectional study to investigate their lesions. Sociodemographic data were collected, HIV infection status and vision tests were performed, and lesions were measured and documented. Lesions >2 mm in diameter were excised and sent for pathology analysis. In addition to the biopsies, tears, blood, and buccal swabs were collected. CD4+ T-cell counts were measured by flow cytometry. Lesions were classified according to the WHO guidelines. χ2 and bivariate correlations were used to analyze variable associations and strengths with phi/Cramer's V and correlation coefficients, respectively. Binary logistics was used to adjust for covariance. RESULTS In this study, 68.3% of the participants were found to be HIV positive. The most frequent diagnoses were invasive OSSN (45.3%), preinvasive OSSN (29.1%), and pterygium (22.6%). Invasive OSSN comprised keratinizing squamous cell carcinoma (SCC) (87.5%), basaloid SCC (3.3%), and spindle cell carcinoma (3.3%). Unusual carcinomas, not described previously, included hybrid SCC (5.0%) and acantholytic SCC (0.8%). Invasive OSSN had advanced tumor (T3/T4) staging (93.3%) at diagnosis. Lymphadenopathy was rare (2.3%), and metastasis was absent. Patients were mostly female (59.2%). Median age was 36 (interquartile ranges 33-41) years (ranges 18-81). Patients with invasive OSSN were more likely to present with pain (p = 0.007), redness (p = 0.034), excessive tearing (p = 0.0001), discharge (p = 0.011), bleeding (p = 0.007), reduced vision (p = 0.0001), fungating lesion (p = 0.001), and blindness (p = 0.005); location at temporal limbus (p = 0.0001), inferior limbus (p = 0.0001), or circumlimbal (p = 0.001); and extension to cornea (p = 0.006) and forniceal palpebral conjunctiva (p = 0.001). Invasive OSSN was associated with any smoking habit and alcohol consumption (p = 0.04 and 0.03, respectively). HIV positivity was strongly associated with OSSN (74.6% OSSN vs. 49.3% benign lesions; p = 0.0001; phi: 0.237 [p = 0.0001]). CONCLUSION OSTs are very common in Zambia and are strongly associated with HIV coinfection. Patients with OSSN were more likely to be HIV positive than those with pterygia. Despite the commonality of OSTs in sub-Saharan Africa, these cancers have historically been poorly characterized.

Single-Fraction Adjuvant Electronic Brachytherapy after Resection of Conjunctival Carcinoma. Cancers (Basel) 2021; 13:cancers13030454. [PMID: 33530293 PMCID: PMC7865874 DOI: 10.3390/cancers13030454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 01/19/2021] [Accepted: 01/22/2021] [Indexed: 11/30/2022] Open
Abstract
Simple Summary A centralized distribution of specialized oncologic facilities is a widely repeated situation in many latitudes around the globe, limiting the patient’s access options to specialized treatments. Strategies to alleviate the overpassed attention capacities in low- and middle-income countries, such as Peru, have driven the attention of practitioners towards hypofractionated treatments. In order to shorten treatment times and hospital visits, treating ocular conjunctival carcinoma with a single-fraction electronic brachytherapy approach arises as a novel option, which further increases the current therapeutic arsenal against this entity. We aim to report the clinical findings of this treatment modality, in terms of feasibility, oncological outcomes and toxicity profile, while opening a new possibility of diminishing patient- and health care-related financial impact. Abstract A retrospective study was performed to assess the outcomes of a single-fraction adjuvant electronic brachytherapy (e-BT) approach for patients with squamous cell conjunctival carcinoma (SCCC). Forty-seven patients with T1–T3 SCCC were included. All patients underwent surgery followed by a single-fraction adjuvant e-BT with a porTable 50-kV device. Depending on margins, e-BT doses ranged between 18 to 22 Gy prescribed at 2 mm depth, resembling equivalent doses in 2 Gy (EQD2) per fraction of 46–66 Gy (α/β ratio of 8–10 Gy and a relative biological effect (RBE) of 1.3). The median age was 69 (29–87) years. Most tumors were T1 (40.4%) or T2 (57.5%) with a median size of 7 mm (1.5–20). Margins were positive in 40.4% of cases. The median time from surgery to e-BT was nine weeks (0–37). After a median follow-up of 24 (17–40) months, recurrence occurred in only two patients (6 and 7 months after e-BT), yielding a median disease-free survival (DFS) of 24 (6–40) months and DFS at two years of 95.7%. Acute grade 2 conjunctivitis occurred in 25.5%. E-BT is a safe and effective for SCCC treatment, with clinical and logistic advantages compared to classical methods. Longer follow-up and prospective assessment are warranted.
