Abstract
PURPOSE To assess the prevalence and subtypes of Human Papillomavirus (HPV) in Ocular Surface Squamous Neoplasia (OSSN) in Human Immunodeficiency Virus (HIV) positive and negative patients in South Africa. BASIC PROCEDURES This study was a single center retrospective cross-sectional study, conducted at Tygerberg Hospital, Western Cape, South Africa. We assessed 63 histopathologically confirmed OSSN formalin-fixed paraffin-embedded (FFPE) tissue blocks from 2015-2023. The presence of HPV was determined using the Hybrispot Direct Flow Chip Kit. Corresponding clinical data was retrieved from the National Health Laboratory Service (NHLS) central data warehouse. MAIN FINDINGS Of the confirmed OSSN samples, 66.7% tested positive for HPV (95% confidence interval [CI] 54-77.3%). Of the 42 HPV positive samples, 38 (90.5%) had one or more known genotypes detected and 4 had unknown genotypes. The most prevalent subtypes were HPV 11, 16 and 18 (found in 61.9%, 52.4% and 33.3% of HPV positive samples respectively). 88.9% of the lesions biopsied were from HIV positive patients, of whom 56.4% had a CD4 + count of < 200 cells/µL. A lower median CD4 + count was detected among HIV positive patients with invasive squamous cell carcinoma compared to those with moderate dysplasia (p < 0.0198). CONCLUSIONS There is a high prevalence of HPV in OSSN in South Africa. Certain subtypes namely, 11, 16, 18, 31, 33 and 35 may be more carcinogenic. HIV with HPV co-infection may be linked as a causative factor in the development of OSSN.

Int Ophthalmol 2024; 44:251. [PMID: 38907750 DOI: 10.1007/s10792-024-03182-x] [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: 04/10/2024] [Accepted: 06/15/2024] [Indexed: 06/24/2024]
Abstract
OBJECTIVE To study the efficacy and side-effect profile of topical 5-Fluorouracil (5-FU) in the treatment of ocular surface squamous neoplasia (OSSN). METHODS Retrospective study of 101 eyes of 100 patients treated with 5-FU with one week on and 3 weeks off regimen. RESULTS Of the 100 patients (101 eyes), the mean age at diagnosis of OSSN was 49 (median, 52 years; range, 11-87 years). History of prior intervention was noted in 6 (6%) eyes. Tumor epicenter included bulbar conjunctiva (n = 54; 53%), limbus (n = 27; 27%), and cornea (n = 20;20%). Mean number of cycles of topical 5-FU administered was 3 (median, 3; range, 1-8). Complete tumor regression was achieved with topical 5-FU in 89 (88%) eyes with a mean number of 2 cycles (median, 2; range, 1-6) of 5-FU. The remaining 12 (12%) lesions underwent additional treatment including excisional biopsy (n = 7), extended enucleation (n = 3), and topical Interferon alpha 2b (n = 2) for complete tumor control. Over a mean follow-up period of 6 months (median, 5 months; range, 1-36 months) following treatment, tumor recurrence was noted in 2 (2%) patients, and side-effects were noted in 7 (7%) eyes including conjunctival hyperemia (n = 1), punctal stenosis (n = 1), sterile keratitis (n = 4), and limbal stem cell deficiency (n = 1). CONCLUSION Topical 5-FU is an effective non-invasive therapy for OSSN with a minimal side-effect profile.

Abstract
Purpose Conjunctival squamous cell carcinoma (conjSCC) is more prevalent and aggressive in sub-Saharan African countries compared with the rest of the world. This study aims to compare the genomic, immunophenotypic, and histologic features between patients from the United States and Ethiopia, to identify etiopathogenic mechanisms and unveil potential treatment strategies. Methods We compared histologic features and mutational profiles using whole exome sequencing, high-risk human papillomavirus (HPV) status, PD-L1 expression, and tumor-infiltrating lymphocytes in conjSCC tumors of patients from Ethiopia (ETH; n = 25) and the United States (from MD Anderson [the MDA cohort]; n = 29). Genomic alterations were compared with SCCs from other anatomic sites using data from The Cancer Genome Atlas. Results Solar elastosis was seen in 78% of ETH and 10% of MDA samples. Thicker tumors had higher density of CD8+ and CD3+ cells. HPV status was similar between the cohorts (ETH = 21% and MDA = 28%). The mean tumor mutation burden (TMB) was significantly higher in conjSCC (3.01/Mb, log10) and cutaneous SCC compared other SCC subtypes. ETH samples had higher TMB compared to the MDA cohort (3.34 vs. 2.73). Mutations in genes associated with ultraviolet light (UV) signature were most frequently encountered (SBS7b = 74% and SBS7a = 72%), with higher prevalence in the ETH cohort, whereas SBS2 and SBS13 signatures were more common among MDA HPV+ conjSCCs. Conclusions Our findings suggest that UV exposure may play a major role in conjSCC, with a higher prevalence in the ETH cohort compared with the MDA cohort, where HPV also contributes.

Abstract
We present the case of a 27-year-old male who presented to our ophthalmology outpatient clinic with a pigmented lesion on the conjunctiva of his right eye. There was no history of ocular trauma or familial ocular complaints, and a thorough evaluation revealed the patient's seropositive status for HIV for the past eight years. The presentation resembled a conjunctival pigmentary lesion, with typical features of ocular surface squamous neoplasia (OSSN) being absent and a demographic incongruent with typical OSSN cases as OSSN typically affects the elderly population. Given the patient's HIV status and the lesion's recent increase in size, a more aggressive treatment approach was warranted. Mass excisional biopsy surgery confirmed conjunctival intraepithelial neoplasia with one positive margin. Adjuvant treatment with mitomycin eye drops (0.04%) resulted in no lesion recurrence at the one-month follow-up. Conjunctival intraepithelial neoplasia can mimic pigmentary lesions in young HIV-positive patients with obvious signs of OSSN being absent. In such cases, the history of seropositivity should be sufficient to suspect it as OSSN and aggressive management measures should be adopted to get best possible outcomes.

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
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
PURPOSE Ocular surface squamous neoplasia (OSSN) comprises a wide spectrum of squamous tumors, from which corneal/conjunctival intraepithelial neoplasia (CIN) is the most common one. The classic treatment is complete excision, but recurrence rates are high. Antineoplastic drugs such as mitomycin C (MMC) and interferon alpha 2b (IFNα2b) have been used as adjuvants or as primary treatment. To evaluate the efficacy and safety of topical IFNα2b and MMC in patients with CIN, a phase IIb double-blind clinical trial was performed. METHODS Patients diagnosed with localized CIN were evaluated by slit lamp and impression cytology and were randomly given MMC 0.04% or INF2b (1 million IU/mL) 4 times daily until neoplasia resolution. Time of resolution and frequency of adverse effects were analyzed to determine the pharmacological efficacy and safety of both medications. RESULTS Seventeen patients were included. Nine patients were treated with MMC and 8 with IFNα2b. All patients responded to treatment. The resolution time in days was 59.11 ± 24.02 in patients treated with MMC and 143.50 ± 47.181 in those treated with IFNα2b (p < 0.001). In the MMC group, one recurrence was reported (11%). There were no recurrences at 2 years of follow-up in the IFNα2b group. Regarding adverse effects, one or more mild adverse reaction occurred in 77% of patients managed with MMC and in 50% of patients managed with IFNα2b (p > 0.05). No serious adverse effects were reported. CONCLUSIONS Topical chemotherapy with MMC and IFNα2b demonstrate pharmacological safety and efficacy. Therefore, these drugs could be considered as primary therapies for localized CIN .

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
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 OF REVIEW Historically, conjunctival cancer has been associated with HIV particularly in sub-Saharan Africa. The human papilloma virus (HPV) has been implicated as a potential causative agent without conclusive evidence. This review covers recent evidence of the epidemiology, diagnosis and treatment of conjunctival cancer in people living with HIV (PLWH). RECENT FINDINGS HIV infection has been attributed to 33% of squamous cell carcinoma of the conjunctiva in sub-Saharan Africa. Although clear evidence of the effect of immunodeficiency on conjunctival cancer risk has been demonstrated, the role of HPV on conjunctival cancer development is still unclear. Biomarkers such as the p16 protein are not always indicative of HPV infection. The Epstein-Barr virus (EBV) might potentially be another infectious agent of interest in the development of conjunctival cancer. There is some evidence of increased conjunctival cancer recurrence post treatment as well as increased probability of metastasis in PLWH. SUMMARY Immunodeficiency increases the risk of conjunctival cancer in PLWH. Symptomatic screening of conjunctival cancer in PLWH should be encouraged. Research on HPV involvement should remain a priority and EBV considered as another etiologic agent of interest. More studies on treatment modalities in PLWH should be considered.

Abstract
Oncocytoma of the eyelid is a rare neoplasm. Oncocytoma associated with an ocular surface squamous neoplasm, namely conjunctival intraepithelial neoplasia, is very hard to find in the literature. Herein we report a case of a 53-year-old male who presented with a swelling in the right lower lid over the last 6 years, along with a growth in the conjunctiva of the same eye for the last 2 years and encroaching upon the cornea for the last 4 months. Excision biopsy of the lower lid mass showed histopathological features consistent with oncocytoma. The conjunctival tissue revealed conjunctival intraepithelial neoplasia 3 (severe dysplasia). This case documents a rare synchronous dual ocular neoplasia, a very unlikely coexistence of oncocytoma with conjunctival intraepithelial neoplasia.

Abstract
Background: Ocular surface squamous neoplasia (OSSN) is a unifying term used to describe conjunctival intra-epithelial neoplasia, squamous cell carcinoma in situ and invasive squamous cell carcinoma.Aim: The aim of this article was to describe the demographics, clinical features, pathogenesis and risk factors of OSSN.Method: A literature search was conducted using the search criteria ‘ocular surface squamous neoplasia’, ‘diagnosis’, ‘epidemiology’, ‘pathogenesis’ and ‘risk factors’.Results: Ocular surface squamous neoplasia is the most common ocular tumour, with incidence rates ranging from 0.01 to 3.4 per 100 000 persons/year. There are two main patterns of disease presentation: older white males in temperate climates where human immunodeficiency virus (HIV) and human papilloma virus (HPV) are not associated; and a younger patient population in tropical climates where HIV and HPV are more prevalent. The pathogenesis primarily revolves around ultraviolet B exposure and HPV infection that cause genetic mutations and uncontrolled cellular proliferation, whilst HIV infection and vitamin A impair tumour surveillance mechanisms. Ocular surface squamous neoplasia is first suspected clinically before formal confirmation of the diagnosis. Morphologically, it can be divided into three groups: placoid, nodular and diffuse. Placoid lesions can further be sub-divided into gelatinous, leukoplakic and papilliform lesions. Nodular lesions have the poorest prognosis, with the highest risk of metastasis and recurrence.Conclusion: Ocular surface squamous neoplasia is a common ocular tumour associated with ultraviolet radiation, HPV and HIV infection. The pathogenesis revolves around acquired genetic mutations, unregulated cellular proliferation and impaired tumour surveillance mechanisms.

Abstract
We estimate the fractions of cancer attributed to infections in Africa in 2018. The number of new cancer cases occurring was taken from Globocan2018 with some additional estimations based on data from African population-based registries. Population attributable fractions were calculated using prevalence of infection and relative risk in exposed vs. nonexposed. The greatest share of infection-associated cancers is due to the human papillomaviruses (12.1% of all cancers in Africa and 15.4% in sub-Saharan Africa [SSA]); of these, cervical cancer is by far the most common. Kaposi sarcoma-associated herpesvirus is responsible for 3.1% of all cancers in Africa, the hepatitis viruses (B and C) for 2.9% and Helicobacter pylori for 2.7% (non-Cardia Gastric cancer and primary gastric lymphomas). Two percent of cancers are attributable to the Epstein-Barr virus, Schistosoma haematobium increases the risk of bladder cancer resulting in 1.0% of all cancers. HIV-related NHL and squamous cell carcinoma of the conjunctiva account for 0.6% of cancers. Altogether 24.5% of cancers in Africa and 28.7% in SSA are due to infectious agents. Infections are by far the most common cancer risk factor for cancer in Africa-the traditional risk factors (smoking, alcohol and unhealthy diet) probably cause only one in eight cancers in Africa. Prevention should focus on those infectious diseases preventable through vaccination (HPV and hepatitis B) which could reduce two-thirds of the burden. Helicobacter pylori and schistosomiasis are treatable with antibiotics and praziquantel, with a potential reduction of one in eight infection-associated cancers.

Abstract
BACKGROUND Ocular surface squamous neoplasia (OSSN) is the most common non-pigmented ocular surface malignancy. It is classified as invasive OSNN (IOSSN) when the underlying stroma are infiltrated by dysplastic squamous epithelial cells through the basement membrane. Here, we present the descriptive epidemiology and geographical distribution of IOSSN in Canada. METHODS We determined the incidence and geographical distribution of IOSSN cases diagnosed between 1992 and 2010 using two independent population-based cancer registries: the Canadian Cancer Registry and Le Registre Québécois du Cancer. RESULTS The mean annual age-standardised incidence rate (WHO 2000-2025) of IOSSN for 1992-2010 was 0.45 cases per million individuals per year with an average annual percent increase in incidence of 4.5%. IOSSN localisation to the conjunctiva was documented in at least 57% of the reported cases. IOSSN exhibited a male predilection ratio of 3.3:1.0 with a mean age at diagnosis of 69 years. Incidence rates of IOSSN across Canadian provinces and cities showed no significant differences from the crude national average. CONCLUSIONS Our results, particularly concerning IOSSN patient age and male predilection, corroborate with data reported from the USA. Additional studies are needed to determine whether the observed increase in incidence rate over the study period (1992-2010) is significant.

Abstract
Conjunctival papilloma is an acquired benign squamous cell tumor that can present at any age, but most frequently in the third and fourth decades of life. Papillomas have been associated with human papilloma virus (HPV) infection, usually types 6 and 11. Although histopathological diagnosis remains the gold standard, the advent of newer non-invasive imaging modalities such as optical coherence tomography (OCT) is transforming the way we diagnose and treat ocular surface tumors, including conjunctival papilloma. Management of these lesions can prove a challenge to the treating physician since not all lesions respond to medical and/or surgical therapy and in fact may worsen after surgical manipulation. In this review, the epidemiology, pathophysiology, clinical characteristics, and diagnosis of conjunctival papilloma including the use of OCT are discussed. Indications, efficacy, and side effects of currently available management options are also reviewed to guide the selection of the best treatment approach.

Abstract
Background A number of risk factors have been evaluated in ocular surface squamous neoplasia, but few studies have assessed risk factors specific to the armed forces veteran population. Methods We conducted a retrospective case-control study on 55 patients and 55 age-matched controls with biopsy-proven ocular surface squamous neoplasia from the Miami Veterans Administration Hospital Eye Clinic to investigate potential risk factors encountered by veterans, including service-specific exposures. Veteran-specific risk factors included ionizing radiation exposure, Agent Orange exposure, deployment to Southwest Asia, and exposure to the series of biochemical warfare tests known as Project Shipboard Hazard and Defense. Data was analyzed with SPSS (SPSS Inc., Chicago, IL) using t-tests, chi-squared, and logistic regression analysis, with a p-value of < 0.05 considered statistically significant. Results The strongest risk factor for ocular surface squamous neoplasia was lifetime sun exposure both directly assessed via historical quantification of exposure by dermatology practitioners (Odds Ratio (OR) 5.4, 95% Confidence Interval (CI) 2.27–12.847, p < 0.005), and using the surrogate markers of basal cell carcinoma (OR 3.157, 95% CI 1.286–7.748, p = 0.010) and pingueculae (OR 5.267, 95% CI 2.104–13.186, p < 0.005). Of the veteran-specific risk factors, Agent Orange exposure and Southwest Asia deployment were not associated with an increased risk of ocular surface squamous neoplasia. Exposure to ionizing radiation and involvement in Project Shipboard Hazard and Defense were not documented among any cases or controls. Conclusions The results of our study are consistent with prior established risk factors, namely highlighting the important role of sun exposure in ocular surface squamous neoplasia among veterans.

Abstract
Background Malignant orbito-ocular tumors are major causes of morbidity and mortality in the developing countries. Their presentation, morphologic type, and management are challenging, and earlier reports were mostly retrospective surveys. Histological analysis is essential in making correct diagnosis. Here, we determined the clinical presentations and histopathologic types of orbito-ocular tumors in some tertiary hospitals in Kano, Nigeria. Materials and Methods This was a prospective cross-sectional multicenter clinical and pathologic study conducted between June 2012 and May 2013. A structured pro forma was used to record findings, patient's biodata, clinical presentation, type of surgical intervention, and histological diagnosis. Data were analyzed with STATA version 11.0. Results Sixty-seven eye tumors were observed among 61 patients. There were 43 males and 18 females (male-to-female ratio = 2.4:1). Patients had a mean of 13.4 ± 18.3 with a median of 4.0 (0.5-70) years with a double peak in age distribution. The most common features were visual loss (90.2%), leukocoria (59%), proptosis (55%), and fungating mass (49.2%). The symptoms were for ≥6 months in 57.4% and unilateral in 82.1%. B-scan showed retinal masses and calcifications in 13.5% and 4.5%, respectively. Confirmation by histology was achieved in 91% with the most common tumor being retinoblastoma, conjunctival squamous cell carcinoma (SCC), and rhabdomyosarcoma with frequencies of 38 (56.6%), 11 (16.4%), and 6 (9.0%), respectively. Six patients were HIV positive and all had SCC. Conclusions Retinoblastoma was the most common malignant orbito-ocular tumor observed in this study. Patients often present late to the hospital with visual loss.

Abstract
PURPOSE To describe the incidence, associations and outcomes of ocular surface squamous neoplasia (OSSN) in the United Kingdom. METHODS Prospective, observational study of every new case of OSSN reported via the British Ophthalmological Surveillance Unit reporting scheme over a 12-month period. Cases were followed up for 12 months. RESULTS The reported incidence of OSSN was 0.53 cases/million/year (conjunctival intraepithelial neoplasia: 0.43 cases/million/year; squamous cell carcinoma: 0.08 cases/million/year). Eighty-five per cent of affected patients were male, 97% were Caucasian, and the mean age at presentation was 67.9 (±12.8) years. Information on potential underlying risk factors was frequently unknown. The most commonly affected sites were the limbus and the nasal and temporal bulbar conjunctivae. Most patients presented with a visual acuity of 6/9 or better, without symptoms of pain or visual loss. Excision (with or without additional treatment) was the most common first-line treatment and interferon (with or without additional treatment) was the most common second-line treatment, although management varied widely. Complications of treatment were rare but occasionally severe. Recurrence within 12 months of follow-up occurred in at least 6% of patients. CONCLUSION Although subject to reporting bias, these data suggest that there has not been a significant change in the incidence of OSSN in the United Kingdom, or its demographic profile, since 1996. The broad range of management approaches identified in this study reflect a lack of consensus as to the optimal referral and treatment pathways.

Abstract
Ocular surface squamous neoplasia (OSSN) is the most common non-pigmented malignancy of the ocular surface and is represented in a wide range of histologic diagnoses, ranging from mild epithelial dysplasia to invasive squamous carcinoma. Although surgical excision is still the gold standard for OSSN treatment, interest in conservative medical approaches is steadily growing. We have reviewed all of the literature on OSSN published in English in the MEDLINE database up to May 2018, using the keywords “ocular surface squamous neoplasia,” “squamous conjunctival carcinoma,” and “conjunctival carcinoma in situ,” with the aim to provide a comprehensive review of the most recent evidence on this distinct clinical entity.

Abstract
Ocular surface squamous neoplasia (OSSN) refers to a spectrum of conjunctival and corneal epithelial tumors including dysplasia, carcinoma in situ, and invasive carcinoma. In this article, we discuss the current perspectives of OSSN associated with HIV infection, focusing mainly on the epidemiology, pathophysiology, clinical manifestations, diagnosis, and treatment of these tumors in patients with HIV. Upsurge in the incidence of OSSN with the HIV pandemic most severely affected sub-Saharan Africa, due to associated risk factors, such as human papilloma virus and solar ultraviolet exposure. OSSN has been reported as the first presenting sign of HIV/AIDS in 26%-86% cases, and seropositivity is noted in 38%-92% OSSN patients. Mean age at presentation of OSSN has dropped to the third to fourth decade in HIV-positive patients in developing countries. HIV-infected patients reveal large aggressive tumors, higher-grade malignancy, higher incidence of corneal, scleral, and orbital invasion, advanced-stage T4 tumors, higher need for extended enucleation/exenteration, and increased risk of tumor recurrence. Current management of OSSN in HIV-positive individuals is based on standard treatment guidelines described for OSSN in the general population, as there is little information available about various treatment modalities or their outcomes in patients with HIV. OSSN can occur at any time in the disease course of HIV/AIDS, and no significant trend has been discovered between CD4 count and grade of OSSN. Furthermore, the effect of highly active antiretroviral therapy on OSSN is controversial. The current recommendation is to conduct HIV screening in all cases presenting with OSSN to rule out undiagnosed HIV infection. Patient counseling is crucial, with emphasis on regular follow-up to address high recurrence rates and early presentation to an ophthalmologist for of any symptoms in the unaffected eye. Effective evidence-based interventions are needed to allow early diagnosis and treatment, as well as prevention of the disease.

Dalvin LA, Salomão DR, Patel SV. Population-based incidence of conjunctival tumours in Olmsted County, Minnesota. Br J Ophthalmol 2018; 102:1728-1734. [PMID: 29511061 DOI: 10.1136/bjophthalmol-2017-311530] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2017] [Revised: 12/27/2017] [Accepted: 02/09/2018] [Indexed: 12/12/2022]
Abstract
AIM To determine population-based incidence of conjunctival tumours in Olmsted County, Minnesota. METHODS The Rochester Epidemiology Project medical record linkage system was used to identify patients with conjunctival tumours in Olmsted County (1 January 1980 to 31 December 2015). Records were reviewed for demographics, types of tumours, histopathology, treatment and clinical course. Incidence rate of all tumours was calculated per 1 000 000 person-years. Poisson regression analysis was used to assess changes in incidence over time. RESULTS There were 504 patients with conjunctival tumours, giving an age-adjusted and sex-adjusted incidence rate of 125 per 1 000 000 (CI 113.5 to 135.5). Incidence increased over time (P<0.001). Most tumours (474, 94%) were benign. Of benign lesions, melanocytic lesions accounted for the majority (431, 86%), with adjusted incidence rates of 10.8 (CI 7.7 to 13.9) for complexion-associated melanosis, 49.7 (CI 42.9 to 56.6) for nevus and 44.1 (37.5-50.8) for primary acquired melanosis. Malignant lesions were rare (30, 6%) with 6 cases of melanoma, 21 cases of ocular surface squamous neoplasia (OSSN), 1 case of Langerhans cell histiocytosis and 2 cases of lymphoma. Adjusted incidence rates of conjunctival melanoma and OSSN were 1.5 (CI 0.3 to 2.8) and 6.1 (CI 3.5 to 8.7), respectively. Outcomes for melanoma (mean follow-up 14 years, range 0-34) and OSSN (mean follow-up 4 years, range 0-24) were favourable in 29 cases, with one fatality due to metastatic melanoma. CONCLUSIONS In a population-based setting, most conjunctival tumours are benign, and the majority of lesions are melanocytic. While it is important to remain vigilant for malignancies, most conjunctival lesions in a community-based practice are not life-threatening.

Abstract
Purpose: The aim is to study the clinicodemographic profile and treatment outcome of ocular surface squamous neoplasia (OSSN). Methods: This was a retrospective observational study of 57 eyes (56 cases) with clinically diagnosed OSSN, presenting in our center over the past year. Results: The median age of presentation was 55 years with male:female ratio being 4.5:1. Systemic predisposing conditions were xeroderma pigmentosa (1) postkidney transplant immunosuppression (1), and human immunodeficiency virus infection (1). Patients with predisposing conditions had a younger median age of onset (33 years). The majority of tumors were nodular (61.4%), gelatinous (61.4%), and had limbal involvement (96%). On ultrasound biomicroscopy (UBM), mean tumor height was 2.93 ± 1.02 mm, and intraocular extension was evident in seven eyes. OSSN with intraocular extension had a mean tumor height of 4.3 ± 1.32 mm. Nodal metastasis was seen in one case at presentation. As per American Joint Committee for Cancer Classification seventh edition staging-two cases were T1, one was T2, 46 were T3 and eight were T4. Treatment advised included conservative therapy for 39; wide local excision (4 mm margin clearance) with cryotherapy for seven; enucleation in four; and exenteration in four eyes. Overall, complete regression was achieved in 88% of cases during a mean follow-up of 13.5 ± 4.6 months. Recurrence was seen in three cases, which were treated with exenteration, radical neck dissection, and palliative chemo-radiotherapy, respectively. Conclusion: Although associated with old age, earlier onset of OSSN is seen in patients with systemic predisposing conditions. Thicker tumors in the setting of a previous surgery or immunocompromised status should be considered high-risk features for intraocular extension and should be evaluated on UBM.

Abstract
PURPOSE To study the importance of routine human immunodeficiency virus (HIV) screening in patients with ocular surface squamous neoplasia (OSSN) and describe their clinical features and management. METHODS Retrospective study. RESULTS Of 228 cases of OSSN screened for HIV by enzyme-linked immunosorbent assay, 86 (38%) patients were HIV positive. Of these 86 patients, 60 (70%) were unaware of their HIV-positive status prior to HIV screening. These 60 (26%) patients with newly detected HIV-positive status were included in this study. Ocular surface squamous neoplasia was the sole presenting feature of HIV infection in these patients. Mean age at presentation was 41 years. Bilateral involvement occurred in 9 (15%) cases. The mean tumor basal diameter was 11 mm. Orbital involvement was noted in 6 (9%) cases, and intraocular tumor extension occurred in 1 (1%) case. Based on American Joint Committee Classification, T2 (n = 35, 51%) was most common. The primary treatment for OSSN included excision biopsy (n = 52, 75%), topical chemotherapy with Mitomycin-C (n = 5, 7%), extended enucleation (n = 4, 6%), and orbital exenteration (n = 8, 12%). Tumor recurrence occurred in 23% cases during a mean follow-up period of 9 months. On histopathology, invasive squamous cell carcinoma was more common (n = 38, 55%). CONCLUSION OSSN was the presenting sign of underlying HIV infection in 26% cases, and 70% were unaware of their HIV-positive status prior to HIV screening. In this study, T2 tumor was most common, and 26% cases required extended enucleation/orbital exenteration to achieve complete tumor resection.

Abstract
OBJECTIVE To determine modifiable risk factors of ocular surface squamous neoplasia (OSSN) in Kenya using disease-free controls. METHODS Adults with conjunctival lesions were recruited at four eye care centres in Kenya and underwent excision biopsy. An equal number of controls having surgery for conditions not affecting the conjunctiva and unrelated to ultraviolet light were group-matched to cases by age group, sex and eye care centre. Associations of risk factors with OSSN were evaluated using multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs). Continuous variables were compared using the t-test or the Wilcoxon-Mann-Whitney U-test depending on their distribution. RESULTS A total of 131 cases and 131 controls were recruited. About two-thirds of participants were female, and the mean age of cases and controls was 42.1 years and 43.3 years, respectively. Risk factors for OSSN were HIV infection without antiretroviral therapy (ART) use (OR = 48.42; 95% CI: 7.73-303.31) and with ART use (OR = 19.16; 95% CI: 6.60-55.57), longer duration of exposure to the sun in the main occupation (6.9 h/day vs. 4.6 h/day, OR = 1.24; 95% CI: 1.10-1.40) and a history of allergic conjunctivitis (OR = 74.61; 95% CI: 8.08-688.91). Wearing hats was protective (OR = 0.22; 95% CI: 0.07-0.63). CONCLUSION Measures to prevent and control HIV, reduce sun exposure such as wearing hats and control allergic conjunctivitis are recommended.

Abstract
We utilized computerized record-linkage methods to link HIV and cancer databases with limited unique identifiers in Pune, India, to determine feasibility of linkage and obtain preliminary estimates of cancer risk in persons living with HIV (PLHIV) as compared with the general population.Records of 32,575 PLHIV were linked to 31,754 Pune Cancer Registry records (1996-2008) using a probabilistic-matching algorithm. Cancer risk was estimated by calculating standardized incidence ratios (SIRs) in the early (4-27 months after HIV registration), late (28-60 months), and overall (4-60 months) incidence periods. Cancers diagnosed prior to or within 3 months of HIV registration were considered prevalent.Of 613 linked cancers to PLHIV, 188 were prevalent, 106 early incident, and 319 late incident. Incident cancers comprised 11.5% AIDS-defining cancers (ADCs), including cervical cancer and non-Hodgkin lymphoma (NHL), but not Kaposi sarcoma (KS), and 88.5% non-AIDS-defining cancers (NADCs). Risk for any incident cancer diagnosis in early, late, and combined periods was significantly elevated among PLHIV (SIRs: 5.6 [95% CI 4.6-6.8], 17.7 [95% CI 15.8-19.8], and 11.5 [95% CI 10-12.6], respectively). Cervical cancer risk was elevated in both incidence periods (SIRs: 9.6 [95% CI 4.8-17.2] and 22.6 [95% CI 14.3-33.9], respectively), while NHL risk was elevated only in the late incidence period (SIR: 18.0 [95% CI 9.8-30.20]). Risks for NADCs were dramatically elevated (SIR > 100) for eye-orbit, substantially (SIR > 20) for all-mouth, esophagus, breast, unspecified-leukemia, colon-rectum-anus, and other/unspecified cancers; moderately elevated (SIR > 10) for salivary gland, penis, nasopharynx, and brain-nervous system, and mildly elevated (SIR > 5) for stomach. Risks for 6 NADCs (small intestine, testis, lymphocytic leukemia, prostate, ovary, and melanoma) were not elevated and 5 cancers, including multiple myeloma not seen.Our study demonstrates the feasibility of using probabilistic record-linkage to study cancer/other comorbidities among PLHIV in India and provides preliminary population-based estimates of cancer risks in PLHIV in India. Our results, suggesting a potentially substantial burden and slightly different spectrum of cancers among PLHIV in India, support efforts to conduct multicenter linkage studies to obtain precise estimates and to monitor cancer risk in PLHIV in India.

Abstract
High-risk human papilloma virus (HR-HPV) is a well-established causative agent of oropharyngeal squamous cell carcinoma (SCC). In addition, HR-HPV has occasionally been reported to be present in dysplastic and malignant lesions of the conjunctiva and lacrimal sac, although its overall incidence and etiological role in periocular SCC are controversial. Sequential surgical samples of 52 combined cases of invasive SCC (I-SCC) and SCC in situ (SCCIS) from 2 periocular sites (conjunctiva and lacrimal sac) diagnosed over a 14-year period (2000 to 2014) were selected for evaluation, and relevant patient characteristics were documented. p16 immunohistochemistry was performed as a screening test. All p16-positive cases were further evaluated for HR-HPV using DNA in situ hybridization (DNA ISH), and a subset was also analyzed by polymerase chain reaction (PCR). Of 43 ocular surface squamous neoplasias (OSSNs), 30% (n=13; 8 SCCIS and 5 I-SCC cases) were positive for HR-HPV. HPV-positive OSSNs occurred in 8 men and 5 women with a mean age of 60 years (range, 39 to 94 y). HPV type-16 was detected in all conjunctival cases evaluated by PCR. All 5 conjunctival I-SCCs were nonkeratinizing (n=4) or partially keratinizing (n=1) and managed by simple excision. In contrast, HPV-negative conjunctival I-SCCs were predominantly keratinizing (11 keratinizing and 2 nonkeratinizing). Of 9 lacrimal sac I-SCCs (LSSCCs), 66.7% (n=6) were positive for HR-HPV by p16 and DNA ISH; HPV subtypes were HPV-16 (n=5) and HPV-58 (n=1). In addition, 2 p16-positive cases with negative DNA ISH results were HR-HPV positive (HPV-16 and HPV-33) when evaluated by PCR, suggesting that the rate of HR-HPV positivity among the LSSCCs may be as high as 89% (n=8). The combined group of HR-HPV-positive LSSCCs was seen in 4 men and 4 women with a mean age of 60 years (range, 34 to 71 y). Seven of the 8 HPV-positive LSSCCs (87.5%) had a nonkeratinizing or partially keratinizing histomorphology, whereas 1 case (12.5%) was predominantly keratinizing. The presence of HR-HPV in 30% of OSSNs and at least 66.7% of LSSCCs suggests the possibility of an etiologic role for HR-HPV at these sites.

A review of the pattern of AIDS defining, HIV associated neoplasms and premalignant lesions diagnosed from 2000-2011 at Kenyatta National Hospital, Kenya. Infect Agent Cancer 2015; 10:28. [PMID: 26306097 PMCID: PMC4547426 DOI: 10.1186/s13027-015-0021-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2014] [Accepted: 07/14/2015] [Indexed: 11/10/2022] Open
Abstract
Background Sub-Sahara Africa hosts up to 71 % of all HIV infected people in the world. With this high incidence of Human immunodeficiency virus ( HIV) comes the burden of co-morbidities such as malignant and premalignant lesions. Aids defining malignancies have been listed as Kaposi’s sarcoma, Non-Hodgkin’s lymphoma and invasive squamous cell carcinoma of the cervix. People with HIV/AIDS(PLWAS) have a higher risk of developing these neoplasms than the rest of the population. The pathogenesis of these neoplasms in people with HIV has been linked to immune suppression, persistent antigenic stimulation and cytokine dysregulation. Current study analyzes and presents the patterns and trends in the presentation of HIV related malignancies in patients diagnosed through histopathology at Kenyatta National Hospital. Aim To describe the patterns of AIDS- defining and non-AIDS- defining malignancies and premalignant lesions 10 years pre- and post HAART period at Kenyatta National hospital, Kenya. Methods and techniques This was a hospital based descriptive cross sectional study. The Formalin fixed paraffin embedded (FFPE) blocks and histological reports of patients diagnosed between 2000 and 2011 were traced from archives. The patients’ demographic data and clinical presentation was entered in an excel spreadsheet and the diagnosis and coding confirmed by a histopathologist. The data was then cleaned and analyzed using SSPS version 17.0 Ink. Results A total of 173 lesions were reviewed and analyzed. Of these 118 (68 %) were from females and 55 from males (32 %). The male to female ratio was 1:2. The age range was from two to 56 years with a median of 36 years. Kaposi sarcoma is the leading AIDS defining malignancy in Kenya while invasive squamous cell carcinoma of the conjunctiva is the leading non-AIDS defining malignancy. This is closely followed by invasive squamous cell carcinoma of the cervix and NHL. Conclusion Kaposi sarcoma is the leading AIDS associated neoplasm in Kenya. Physicians and caretakers managing and following up on HIV/AIDS patients should look out for Kaposi sarcoma as a form of IRIS following the institution of HAART in all HIV/AIDS patients. The incidence of invasive squamous cell carcinoma of the conjunctiva is increasing in PLWAS in Kenya. There is therefore a need to introduce early screening programs for squamous intraepithelial neoplasm of the conjunctiva in HIV/AIDS patients.

Predictors of HIV/AIDS Related Ocular Manifestations among HIV/AIDS Patients in Felege Hiwot Referral Hospital, Northwest Ethiopia. J Ophthalmol 2015; 2015:965627. [PMID: 26000175 PMCID: PMC4427099 DOI: 10.1155/2015/965627] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2015] [Revised: 04/17/2015] [Accepted: 04/19/2015] [Indexed: 11/30/2022] Open
Abstract
Background. Ocular manifestations in people living with HIV/AIDS are varied and affect almost all the structures of eye leading to visual impairment or blindness. Therefore, the aim of this study was to identify the predictors of HIV related ocular manifestation among ART clinic clients. Methods. Institution based cross-sectional study was employed among ART clients at Felege Hiwot referral hospital, northwest Ethiopia. The study was conducted from 1 January 2013 to 30 January 2013. A total of 369 systematically and randomly selected clients were included in the study. Data were collected using structured questionnaires and ophthalmologic clinical examination. Data were entered and analyzed using SPSS version 16.0. Binary and multivariable logistic regression analyses were computed to identify independent predictors of HIV related ocular manifestation. Results. Twenty-five percent (25.7%) of HIV patients had ocular manifestations. The three most frequent signs were Squamoid Conjuctival growth (26.9%), ophthalmic herpes zoster (22.1%), and Bacterial Conjuctivitis (17.2%). History of eye problem, CD4 count, and visual acuity of the eye were the predictors of HIV related ocular manifestation. Conclusion. In this study, a higher proportion of ocular manifestations were detected in HIV/AIDS patients. Visual acuity and CD4 counts were the independent predictors of ocular manifestations. This finding gives an insight for policy makers and concerned body to integrate ophthalmic examination in ART clinics to improve the health condition of HIV/ADIS patients.

Abstract
OBJECTIVE To determine the prevalence of HIV seropositivity among patients with squamous cell carcinoma of the conjunctiva. METHODS All patients with clinical and histopathological confirmation of squamous cell carcinoma seen during a ten year period (July 1999 to June 2009) were tested for HIV (Human Immunodeficiency Virus). The number of patients with squamous cell carcinoma of the conjunctiva who are HIV positive were counted. RESULTS A total of thirty-three (33) eyes in thirty-two (32) patients were confirmed histopathologically to have conjunctival squamous cell carcinoma. Their ages ranged from 22 years to 66 years with a mean age of (38.6 ± 11.8) years (SD). The male to female ratio was 1:1.5. Twenty four (75%) of these patients were HIV positive. CONCLUSIONS Squamous cell carcinoma is associated with the human immunodeficiency virus and is thus a marker for the disease in Benin City, Nigeria.

Abstract
Background Ocular surface squamous neoplasia (OSSN) is becoming increasingly prevalent and aggressive in Sub-Saharan Africa. It is a phenomenon linked with human immunodeficiency virus (HIV) infection, although association rates in Angola are currently unknown. A topical treatment that is effective in HIV-positive and HIV-negative individuals may be preferable to surgery in some contexts. We aimed to estimate the proportion of OSSN associated with HIV in Angola and to report on the success of topical 5-fluorouracil as a primary treatment in HIV-positive and HIV-negative patients. Methods Photographs of OSSNs taken at presentation and following treatment with 5-fluorouracil in patients presenting to Boa Vista Eye Clinic, Angola, between October 2011 and July 2013 were grouped into HIV-positive and HIV-negative groups and analyzed to compare presenting features and treatment response. Eighty-one OSSNs were analyzed for clinical features and 24 met the inclusion criteria for analysis of treatment response. Results Eighty-two patients presented with OSSN between October 2011 and July 2013. Twenty-one (26%) were HIV-positive and typically had OSSNs that exhibited more pathological features than those in HIV-negative patients. Twenty-four (29%) patients met the inclusion criteria for analysis of treatment response; of these, 26 (91%) OSSNs in both groups displayed at least partial resolution after one treatment course. In the HIV-positive group, five of eight patients displayed complete resolution, two showed partial resolution, and one failed. In the HIV-negative group, five of 16 showed complete resolution, ten of 16 had partial resolution, and one failed. Conclusion Individuals presenting with OSSN in Angola are more likely to have HIV infection compared with the general population. Regardless of HIV status, 5-fluorouracil drops can be an effective strategy for management of OSSN without incurring the costs and risks of surgery in the developing world setting.

Correlation of EGFR, pEGFR and p16INK4 expressions and high risk HPV infection in HIV/AIDS-related squamous cell carcinoma of conjunctiva. Infect Agent Cancer 2014; 9:7. [PMID: 24572046 PMCID: PMC3996052 DOI: 10.1186/1750-9378-9-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2013] [Accepted: 02/11/2014] [Indexed: 12/17/2022] Open
Abstract
Background Squamous cell carcinoma of conjunctiva has increased tenfold in the era of HIV/AIDS. The disease pattern has also changed in Africa, affecting young persons, with peak age-specific incidence of 30-39 years, similar to that of Kaposi sarcoma, a well known HIV/AIDS defining neoplasm. In addition, the disease has assumed more aggressive clinical course. The contributing role of exposure to high risk HPV in the development of SCCC is still emerging. Objective The present study aimed to investigate if immunohistochemical expressions of EGFR, pEGFR and p16, could predict infection with high risk HPV in HIV-related SCCC. Methods FFPE tissue blocks of fifty-eight cases diagnosed on hematoxylin and eosin with SCCC between 2005-2011, and subsequently confirmed from medical records to be HIV positive at the department of human pathology, UoN/KNH, were used for the study. Immunohistochemistry was performed to assess the expressions of p16INK4A, EGFR and pEGFR. This was followed with semi-nested PCR based detection and sequencing of HPV genotypes. The sequences were compared with the GenBank database, and data analyzed for significant statistical correlations using SPSS 16.0. Ethical approval to conduct the study was obtained from KNH-ERC. Results Out of the fifty-eight cases of SCCC analyzed, twenty-nine (50%) had well differentiated (grade 1), twenty one (36.2%) moderately differentiated (grade 2) while eight (13.8%) had poorly differentiated (grade 3) tumours. Immunohistochemistry assay was done in all the fifty eight studied cases, of which thirty nine cases (67.2%) were positive for p16INK4A staining, forty eight cases (82.8%) for EGFR and fifty one cases (87.9%) showed positivity for p-EGFR. HPV DNA was detected in 4 out of 40 SCCC cases (10%) in which PCR was performed, with HPV16 being the only HPV sub-type detected. Significant statistical association was found between HPV detection and p16INK4 (p=0.000, at 99% C.I) and EGFR (p=0.028, at 95% C.I) expressions, but not pEGFR. In addition, the expressions of these biomarkers did not show any significant association with tumor grades. Conclusion This study points to an association of high risk HPV with over expressions of p16INK4A and EGFR proteins in AIDS-associated SCCC.

Abstract
The incidence of AIDS-defining cancers (ADCs) - Kaposi sarcoma, primary central nervous system lymphoma, non-Hodgkin lymphoma, and cervical cancer - although on the decline since shortly after the introduction of HAART, has continued to be greater even in treated HIV-infected persons than in the general population. Although the survival of newly infected people living with HIV/AIDS now rivals that of the general population, morbidity and mortality associated with non-AIDS-defining cancers (NADCs) such as lung, liver, anal, and melanoma are significant and also continue to rise. Increasing age (i.e. longevity) is the greatest risk factor for NADCs, but longevity alone is not sufficient to fully explain these trends in cancer epidemiology. In this review, we briefly review the epidemiology and etiology of cancers seen in HIV/AIDS, and in this context, discuss preclinical research and broad treatment considerations. Investigation of these considerations provides insight into why malignancies continue to be a major problem in the current era of HIV/AIDS care.

Diagnosing ocular surface squamous neoplasia in East Africa: case-control study of clinical and in vivo confocal microscopy assessment. Ophthalmology 2013; 121:484-91. [PMID: 24321141 PMCID: PMC3901930 DOI: 10.1016/j.ophtha.2013.09.027] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2013] [Revised: 09/06/2013] [Accepted: 09/18/2013] [Indexed: 12/31/2022] Open
Abstract
OBJECTIVE To examine the reliability of clinical examination and in vivo confocal microscopy (IVCM) in distinguishing ocular surface squamous neoplasia (OSSN) from benign conjunctival lesions. DESIGN Case-control study. PARTICIPANTS Sixty individuals with conjunctival lesions (OSSN and benign) and 60 age-matched controls with normal conjunctiva presenting to Kilimanjaro Christian Medical Centre, Moshi, Tanzania. METHODS Participants were examined and photographed, and IVCM was performed. Patients with conjunctival lesions were offered excisional biopsy with histopathology and a human immunodeficiency virus (HIV) test. The IVCM images were read masked to the clinical appearance and pathology results. Images were graded for several specific features and given an overall categorization (normal, benign, or malignant). A group of 8 ophthalmologists were shown photographs of conjunctival lesions and asked to independently classify as OSSN or benign. MAIN OUTCOME MEASURES Comparison of the histopathology diagnosis with the clinical and IVCM diagnosis. RESULTS Fifty-two cases underwent excisional biopsy with histopathology; 34 were on the OSSN spectrum, 17 were benign, and 1 was lymphoma. The cases and controls had comparable demographic profiles. Human immunodeficiency syndrome infection was more common in OSSN compared with benign cases (58.8% vs. 5.6%; odds ratio, 24.3, 95% confidence interval [CI], 2.8-204; P = 0.003). Clinically, OSSN lesions more frequently exhibited feeder vessels and tended to have more leukoplakia and a gelatinous appearance. Overall, the ophthalmologists showed moderate agreement with the histology result (average kappa = 0.51; 95% CI, 0.36-0.64). The masked grading of IVCM images reliably distinguished normal conjunctiva. However, IVCM was unable to reliably distinguish between benign lesions and OSSN because of an overlap in their appearance (kappa = 0.44; 95% CI, 0.32-0.57). No single feature was significantly more frequent in OSSN compared with benign lesions. The sensitivity and specificity of IVCM for distinguishing OSSN from benign conjunctival lesions were 38.5% and 66.7%, respectively. CONCLUSIONS In East Africa, conjunctival pathology is relatively common and can present significant diagnostic challenges for the clinician. In this study, neither clinical examination nor IVCM was found to reliably distinguish OSSN from benign conjunctival pathology because of an overlap in the features of these groups. Therefore, IVCM cannot currently replace histopathology, and management decisions should continue to rely on careful clinical assessment supported by histopathology as indicated.

Abstract
OBJECTIVES To describe the epidemiology and an aetiological model of ocular surface squamous neoplasia (OSSN) in Africa. METHODS Systematic and non-systematic review methods were used. Incidence was obtained from the International Agency for Research on Cancer. We searched PubMed, EMBASE, Web of Science and the reference lists of articles retrieved. Meta-analyses were conducted using a fixed-effects model for HIV and cigarette smoking and random effects for human papilloma virus (HPV). RESULTS The incidence of OSSN is highest in the Southern Hemisphere (16° South), with the highest age-standardised rate (ASR) reported from Zimbabwe (3.4 and 3.0 cases/year/100 000 population for males and females, respectively). The mean ASR worldwide is 0.18 and 0.08 cases/year/100 000 among males and females, respectively. The risk increases with exposure to direct daylight (2-4 h, OR = 1.7, 95% CI: 1.2-2.4 and ≥5 h OR = 1.8, 95% CI: 1.1-3.1) and outdoor occupations (OR = 1.7, 95% CI: 1.1-2.6). Meta-analysis also shows a strong association with HIV (6 studies: OR = 6.17, 95% CI: 4.83-7.89) and HPV (7 studies: OR = 2.64, 95% CI: 1.27-5.49) but not cigarette smoking (2 studies: OR = 1.40, 95% CI: 0.94-2.09). The effect of atopy, xeroderma pigmentosa and vitamin A deficiency is unclear. CONCLUSIONS Africa has the highest incidence of OSSN in the world, where males and females are equally affected, unlike other continents where male disease predominates. African women probably have increased risk due to their higher prevalence of HIV and HPV infections. As the survival of HIV-infected people increases, and given no evidence that anti-retroviral therapy (ART) reduces the risk of OSSN, the incidence of OSSN may increase in coming years.

Abstract
CASE REPORT A 67 year-old male seen for a longstanding corneal-conjunctival tumor. TREATMENT topical interferon α2b (IFN-α2b) 10 U/ml. A significant increase in lesion size was observed after 8 weeks. A surgical excision with cryotherapy was then performed. Pathological examination confirmed the diagnosis of squamous cell carcinoma. At this time the patient was found to have a positive HIV serology. DISCUSSION Conjunctival intraepithelial neoplasia (CIN) is a pre-cancerous lesion of the ocular surface. Medical treatment of CIN is essentially with IFN-α2b due to its antiviral/antitumor properties. In patients with HIV, treatment response could be paradoxical. We recommend serology for HIV before treatment with topical IFN-α2b.

Abstract
Background Although frequently underdiagnosed, squamous cell carcinoma is the most commonly observed malignancy of the conjunctiva. Multiple different treatments have been proposed to date. The purpose of this paper is to report our experience in the treatment of In situ carcinoma of the conjunctiva by surgical excision associated with cryotherapy. Methods Four eyes in four consecutive patients (two men and two women) of average age 53.2 (range 39–71) years at the time of diagnosis of ocular surface squamous neoplasia were treated by simple surgical excision and cryotherapy of the resulting surgical bed margins. In all cases, the diagnosis of in situ carcinoma was confirmed histopathologically. Results On histopathology, the edges of the surgical specimens were free of malignant cells in three of four patients. All patients showed excellent evolution without recurrence. Mean follow-up was 6.5 (range 2–14) years. Conclusion In situ carcinoma of the conjunctiva may be simply and successfully treated with surgical excision and cryotherapy.

Abstract
BACKGROUND The frequency of ocular surface squamous neoplasias (OSSNs) has been increasing in populations with a high prevalence of infection with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and infection with human papillomavirus (HPV). We aimed to quantify the association between HIV/AIDS and HPV infection and OSSN, through systematic review and meta-analysis. METHODS The articles providing data on the association between HIV/AIDS and/or HPV infection and OSSN were identified in MEDLINE, SCOPUS and EMBASE searched up to May 2013, and through backward citation tracking. The DerSimonian and Laird method was used to compute summary relative risk (RR) estimates and 95% confidence intervals (95% CI). Heterogeneity was quantified with the I(2) statistic. RESULTS HIV/AIDS was strongly associated with an increased risk of OSSN (summary RR=8.06, 95% CI: 5.29-12.30, I(2)=56.0%, 12 studies). The summary RR estimate for the infection with mucosal HPV subtypes was 3.13 (95% CI: 1.72-5.71, I(2)=45.6%, 16 studies). Four studies addressed the association between both cutaneous and mucosal HPV subtypes and OSSN; the summary RR estimates were 3.52 (95% CI: 1.23-10.08, I(2)=21.8%) and 1.08 (95% CI: 0.57-2.05, I(2)=0.0%), respectively. CONCLUSION Human immunodeficiency virus infection increases the risk of OSSN by nearly eight-fold. Regarding HPV infection, only the cutaneous subtypes seem to be a risk factor.

Abstract
PURPOSE OF REVIEW Ocular surface malignancy is a serious complication in HIV infection, but can often result in successful treatment if diagnosed appropriately. In the literature, most reviews focus on information for the ophthalmic community. Here, we provide a review of the literature with the pertinent information for the nonophthalmologist, as they are the first point of contact for most HIV patients. RECENT FINDINGS Ocular surface squamous neoplasia (OSSN) is the most common nonpigmented ocular surface malignancy. It can be treated well with surgery or topical chemotherapy, the newest method of treatment. When presenting in young patients, a high percentage have been found to be HIV positive. Kaposi's sarcoma is an AIDS-defining malignancy and critical to diagnose. It cannot be cured, but treatment is effective for keeping it controlled. Conjunctival lymphoma can be recognized with the salmon patch appearance. External beam radiation, systemic chemotherapy, and intralesional injections are the mainstays of treatment. SUMMARY Ocular surface malignancy manifests significantly in the HIV population. OSSN, Kaposi's sarcoma and conjuctival lymphoma all have different clinical presentations. The capacity of the managing physician to recognize these tumours and refer to an ophthalmologist is essential for appropriate treatment.

Abstract
PURPOSE To evaluate the prevalence of undiagnosed and asymptomatic human immunodeficiency virus (HIV) infection in patients with ocular surface squamous neoplasia (OSSN) in a referral hospital in Karnataka, South India. METHODS A consecutive series of patients presenting with OSSN were evaluated in an academic center during January 2009 to June 2010. A detailed history was obtained and physical examination in 25 consecutive patients with OSSN was performed. Twenty-three patients (88%) agreed to undergo serological HIV testing. Of these, 2 were excluded from the current study because they had xeroderma pigmentosa, a known predisposing factor for OSSN. RESULTS Of the 21 patients, 6 (29%) patients were HIV positive. None of the patients had previous HIV testing. The median age of presentation among HIV-positive patients was 36 years, whereas it was 54 years among HIV-negative patients. The mean CD4 count in HIV-positive patients was 133 cells per mm, and all patients were started on antiretroviral treatment. CONCLUSIONS The conjunctival tumor may be the primary and the only apparent manifestation of HIV in patients presenting with OSSN, and the ophthalmologist needs to be aware of this association.

Abstract
BACKGROUND Squamous cell carcinoma of the conjunctiva is described in the ophthalmic literature as a rare, slow-growing tumour of the eye, normally affecting elderly men around 70 years of age. In Africa, however, the disease is different. The incidence is rising rapidly, affecting young persons (around 35 years of age), and usually affecting women. It is more aggressive, with a mean history of three months at presentation. This pattern is related to the co-existence of the HIV/AIDS pandemic, high HPV exposure, and solar radiation in the region. Various interventions exist, but despite therapy, there is a high recurrence rate (up to 43%) and poor cosmetic results in late disease. This review was conducted to evaluate the interventions for treatment of conjunctival squamous cell carcinoma in HIV-infected individuals. OBJECTIVES To evaluate the effect of interventions for treating squamous cell carcinoma of the conjunctiva in HIV-infected individuals on local control, recurrence, death, time to recurrence, and adverse events. SEARCH METHODS Using a sensitive search strategy, we attempted to identify all relevant trials, regardless of language or publication status, from the following electronic databases; PubMedPubMed, EMBASE and The Cochrane Library. We also searched clinical trial registries; WHO International Clinical Trials Registry Platform (ICTRP) and the US National Institutes of Health Clinicaltrials.gov. We searched the international conference proceedings of HIV/AIDS and AIDS-related cancers from the AIDS Education Global Education System (AEGIS). Searches were conducted between January and February 2012. SELECTION CRITERIA Randomised controlled trials (RCTs) involving HIV-infected individuals with ocular surface squamous neoplasia. DATA COLLECTION AND ANALYSIS We independently screened the results of the search to select potentially relevant studies and to retrieve the full articles. We independently applied the inclusion criteria to the potentially relevant studies. No studies were identified that fulfilled the selection criteria. MAIN RESULTS No RCTs of interventions currently used against conjunctival squamous cell carcinoma in HIV-infected individuals were identified.There is one ongoing RCT in Kenya that was registered in July 2012. IMPLICATIONS FOR PRACTICE Current clinical practice in treatment of squamous cell carcinoma of the conjunctiva rests on a weak evidence base of case series and case reports. IMPLICATIONS FOR RESEARCH Randomised controlled trials for treatment of this disease are needed in settings where it occurs most frequently. Preventive interventions also need to be identified. HIV/AIDS research has not focused on treatment of this tumour.

Abstract
Purpose We describe two patients with squamous cell papilloma of the conjunctiva due to human papilloma virus (HPV) and review the literature. Patients and methods Two patients with conjunctival tumors were examined and treated in the University Eye Clinic and diagnosed in the University Pathology Department, University Hospital of Ioannina, Greece. The first patient was a 48-year-old man presenting with an extended papillomatous lesion in bulbar conjunctiva covering part of the cornea of his right eye. The second patient was a 24-year-old man presenting with a polypoidal papillomatous lesion on the caruncle of his right eye. The two lesions were removed surgically, cryotherapy was applied to the adjacent conjunctiva, and topical mitomycin-C was used. The amniotic membrane was used to restore the conjunctival defect in the first patient. The two removed lesions were sent to the Pathology Department for histopathological examination. Immunohistochemistry, DNA in situ hybridization, and polymerase chain reaction (PCR) analysis were performed. Results In the first patient, histopathology showed the presence of a benign squamous papilloma with koilocytosis. DNA in situ hybridization with broad-spectrum probes showed that this patient was positive for HPV DNA. In the second patient, histopathology showed the presence of a squamous papilloma with mild dysplasia and koilocytosis. Immunohistochemical analysis was positive for HPV protein and p16 protein. DNA in situ hybridization with broad-spectrum probes showed that the patient was positive for HPV DNA. PCR analysis showed the presence of HPV 6. According to morphological and molecular findings, both patients were diagnosed with squamous cell papilloma due to HPV. Conclusion HPV can infect the ocular surface. According to clinical results, the ophthalmologist in cooperation with the pathologist can recommend appropriate laboratory examinations to confirm the diagnosis and successfully treat conjunctival papillomas.
