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
PURPOSE To elucidate the efficacy and safety profile of interferon α-2b in vernal keratoconjunctivitis (VKC). METHODS In this prospective interventional study, VKC patients fulfilling the inclusion and exclusion criteria were included and their signs and symptoms were scored based on the Clinical Scoring System. Patients were treated with topical interferon α-2b eye drop (1 MIU/ml) QID dosing for 6 weeks. Changes in symptoms and signs were evaluated at 2, 4, 8 weeks and 6 months after initiating treatment. A higher score meant severe disease, and a decline in score meant improvement in clinical signs and symptoms. Categorical variables were presented in number and percentage (%) and continuous variables as mean ± standard deviation (SD). Post-medication total subjective symptom score (TSSS) and total objective sign score (TOSS) were compared with baseline, and a P- value of <0.05 was considered significant. Possible ocular and systemic complications were evaluated. RESULTS The study included 40 patients (32 male and eight female) with a mean age of 8.05 ± 2.33 years. Mean baseline TSSS and TOSS were 6.71 ± 0.564 and 6.59 ± 0.262, respectively, which reduced to 2.71 ± 0.011 ( P = 0.040) and 2.96 ± 0.210 ( P = 0.032), respectively, at 4 weeks and further reduced to 0.42 ± 0.552 and 0.47 ± 0.434, respectively, at 8 weeks. After 6 months of stopping the drug, mean TSSS and TOSS did increase to 2.80 ± 0.820 ( P = 0.044) and 2.50 ± 0.520 ( P = 0.030), respectively, but was still statistically significant improvement compared to the baseline. Also, no ocular or systemic side effects were observed anytime during the study period. CONCLUSION Eye drop interferon α-2b (1 million IU/ml) is a safe and effective option as first-line monotherapy for VKC. No side effects and recurrence were observed for 6 months.

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 The aim of this study was to report clinical observations suggesting the efficacy of topical 1% 5-fluorouracil (5-FU) in treating Demodex -associated blepharitis. METHODS An observational retrospective review of 13 eyes from 13 individuals with conjunctival neoplastic lesions and concomitant Demodex lash infestation that received topical 1% 5-FU eye drops. Patients underwent slit-lamp examination at each follow-up visit. Clinical photographs of the lash line were obtained after treatment initiation. In a subset of patients, lashes were epilated bilaterally and microscopically analyzed for presence of Demodex mites before and after treatment initiation. RESULTS The mean age of the population was 68 ± 14 years (range: 30-84 years) and 92% were male. In all 13 patients, a marked reduction in cylindrical dandruff was noted in the treated eye by slit-lamp examination after 2 cycles of 5-FU. There was complete resolution of cylindrical dandruff in 10 of 13 treated eyes compared with 0 resolution of cylindrical dandruff in untreated eyes ( P = 0.0001). In the 6 patients who received epilation, the lashes from the treated eye showed no Demodex , whereas lashes from the fellow untreated eye revealed persistent Demodex . CONCLUSIONS Topical 1% 5-FU shows efficacy in treating Demodex -associated blepharitis. Further studies are indicated to reproduce our findings and evaluate the potential use of 5-FU as a treatment ingredient.

Abstract
PURPOSE To evaluate the efficacy of topical treatment with 5-Fluorouracil (5-FU) 0.5% in cases of Ocular Surface Squamous Neoplasia (OSSN), and to assess the tolerance of patients undergoing treatment. METHODS Patients with clinical diagnosis of OSSN referred to the Ocular Oncology division from the Federal University of Sao Paulo, Brazil, were recruited for the current study. Patients were treated with topical 5-FU 0.5% using a regimen of 4 times daily for 10 days, followed by a 3-week drug holiday, continued up to 3 cycles before an alternative treatment. Lesions were evaluated at baseline and throughout treatment. Treatment adherence was assessed using the Morisky Medication Adherence scale. Any adverse events along the treatment were noted. RESULTS A total of 30 eyes of 30 patients adherent to the treatment were included in the study. Among the total cases treated with 5-FU 0.5%, 24 patients achieved therapeutic success after a mean treatment duration of 21.71 ± 7.77 days, representing a success rate of 80.00% (95% CI: 60.75-91.18%). For each 1 mm2 increase in the lesion area, the odds of treatment success decrease by 6% (OR: 0.94; 95%CI: 0.88-0.99; p = 0.033). Only mild adverse events such as ocular discomfort, ocular burning and tearing were observed along the treatment in 8 patients. CONCLUSIONS Topical 5-FU 0.5% is an effective therapeutic option in the treatment of OSSN, with an 80% therapeutic success rate, showing good tolerability. The size of the lesion was identified as a factor influencing treatment success, therefore it should be taken into consideration when defining treatment approaches.

Abstract
Background The periocular skin is neoplasms-prone to various benign and malignant. Periocular malignancies are more aggressive and challenging to cure and repair than those in other skin areas. In recent decades, immunotherapy has significantly advanced oncology, allowing the autoimmune system to target and destroy malignant cells. Skin malignancies, especially periocular tumors, are particularly sensitive to immunotherapy. This technique has dramatically impacted the successful treatment of challenging tumors. Main text Extraocular cancers, including eyelid (basal cell carcinoma, squamous cell carcinoma, melanoma, merkel cell carcinoma), conjunctival tumors (conjunctival melanoma, ocular surface squamous neoplasia) and other rare tumors, are unique and challenging clinical situations. Several genetic alterations associated with the pathogenesis of these diseases have been identified, and molecular mechanism are essential for the development of the immunotherapy agents, such as Hedgehog pathway inhibitors (vismodegib and sonidegib) for basal cell carcinoma, BRAF/MEK inhibitors (vemurafenib, dabrafenib, and encorafenib) for melanoma, and immune checkpoint inhibitors (Avelumab, pembrolizumab) for Merkel cell carcinoma. Conclusions The optimal treatment for periocular skin cancer depends on the type and size of the tumor and whether it involves orbital and adnexal structures. Adjuvant and neoadjuvant therapy with chemotherapy-targeted therapies and immune checkpoint inhibitors should be considered based on tumor type, tumor molecular profile, expected response rate, and candidacy for systemic treatment.

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
Purpose To report clinical features and treatment outcome of three cases with isolated corneal intraepithelial neoplasia (CIN). Methods This case series presents 3 patients with isolated CIN. Data collected included, presenting signs and symptoms including vision, anterior segment examination, medical and surgical outcomes and signs and symptoms at lost post-treatment visit. Results Case 1 was a 45-year-old male who presented with an isolated grayish amoeboid corneal lesion which was excised with alcohol assisted epitheliectomy, he also received 6 cycles of topical mitomycin C (MMC) 0.02% and one injection of interferon alfa-2b with no recurrence during the 10-year follow-up period. Case 2 was 78-year-old male referred for a suspicious white corneal lesion which was completely excised, the patient also received 6 subconjunctival injections of interferon alpha-2b. However, the lesion recurred at 2.5-years post-treatment. Case 3 was a 63-year-old male patient who presented with an isolated corneal lesion that was excised using alcohol-assisted epitheliectomy, patient received four cycles of topical 5-fluorouracil with no recurrence at last follow-up visit at 6 months. Conclusion Isolated corneal intraepithelial neoplasia (CIN) is a rare entity with few reported cases in the literature. In this case series, we report long and short-term management outcomes of combined surgical and medical therapy for isolated CIN.

[PMID: 37501105 PMCID: PMC10373405 DOI: 10.1186/s12886-023-03092-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 07/20/2023] [Indexed: 07/29/2023] Open
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
Ocular surface squamous neoplasia (OSSN) is the major cause of corneal cancer in man and horses worldwide, and the prevalence of OSSN is increasing due to greater UVB exposure globally. Currently, there are no approved treatments for OSSN in either species, and most patients are managed with surgical excision or off-label treatment with locally injected interferon alpha, or topically applied cytotoxic drugs such as mitomycin C. A more broadly effective and readily applied immunotherapy could exert a significant impact on management of OSSN worldwide. We therefore evaluated the effectiveness of a liposomal TLR complex (LTC) immunotherapy, which previously demonstrated strong antiviral activity in multiple animal models following mucosal application, for ocular antitumor activity in a horse spontaneous OSSN model. In vitro studies demonstrated strong activation of interferon responses in horse leukocytes by LTC and suppression of OSSN cell growth and migration. In a trial of 8 horses (9 eyes), treatment with topical or perilesional LTC resulted in an overall tumor response rate of 67%, including durable regression of large OSSN tumors. Repeated treatment with LTC ocular immunotherapy was also very well tolerated clinically. We conclude therefore that ocular immunotherapy with LTC warrants further investigation as a novel approach to management of OSSN in humans.

Abstract
PURPOSE To assess the efficacy of topical interferon α-2β(IFN) eye drops as a primary treatment for ocular surface squamous neoplasia(OSSN) and evaluate factors that impact response to treatment and recurrence of OSSN. METHOD A retrospective study of 143 OSSN patients treated with topical IFN(1MIU/ml) from January 1998 to June 2021. The diagnosis was based on clinical examination and anterior segment optical coherence tomography, with histologic confirmation was present in 46.2% of patients. Data on demographic, tumor characteristics, treatment outcome, and side effects were collected. The primary outcomes were tumor resolution frequency and recurrence rate. Secondary outcomes were predictive factors for resolution and recurrence and side effects of treatment. RESULT Participants were mostly older (mean age, 69 years, SD 12.9, range 29-97), white(89%) males (74%). Complete tumor resolution was achieved in 80.4% of individuals with a mean time to resolution of 4.2 months (SD 2, range 0.5-12.3 months). On multivariable analysis, history of skin cancer (HR: 0.66, p = 0.05, 95%CI: 0.44-0.99) and immune system abnormalities (HR: 0.37, p = 0.009, 95%CI: 0.18-0.79) reduced the risk of tumor resolution, while a prior history of OSSN (HR: 3.49, p < 0.001, 95%CI: 1.76-6.93) increased the risk of resolution. With a mean follow-up time of 44.3 months (SD 50.9, 0-290 months), the recurrence rate was 0%, 2.3% and 3.1% at 1, 2, and 5 years respectively. Mild hyperemia(18.9%) and pain(10.6%) were the two most common side effects. CONCLUSION Topical IFN eye drops are a safe and effective primary treatment modality for OSSN with a reasonable side effect profile.

Abstract
BACKGROUND Conjunctival papilloma is often resistant to treatment. Various therapies have been reported with no gold standard. The purpose of this study was to compare treatment outcomes after various therapies. METHODS A retrospective chart review of 30 conjunctival papilloma patients from 2009-2020. Data on demographics, tumour characteristics, primary treatment and outcomes were collected. The primary outcome was the frequency of complete tumour resolution and recurrence rate of each primary therapy. The secondary outcome was treatment related side effects. RESULTS The mean age was 57.5 years (3-93 years) with male predominance (n = 22, 73.3%). Eleven eyes were treated with interferon α-2b (IFN), seven with 5-fluorouracil (5FU), and 10 with excision biopsy and cryotherapy (6 with adjuvant therapy with IFN). The frequency of tumour resolution was 36.4% (4/11), 28.5% (2/7), and 100% (10/10) in each group, respectively. The mean time to resolution was faster in the surgical group compared to the medical group (1 day vs 159 days, p < 0.001). There was higher tumour recurrence with 11% in the surgical vs 0% in the medical group at 6 months and at 12 months, 22% recurrence in the surgical and 0% in the medical group (p = 0.52). However, the differences were not statistically significant. CONCLUSION Papilloma resolution is faster with surgical excision as compared to medical therapy. However, recurrences are more frequent after surgical versus medical treatment.

Abstract
Ocular surface squamous neoplasia (OSSN) is the most common non-melanocytic tumour of the ocular surface. Surgical excision with wide margins using the "no-touch" method was originally the most popular treatment for OSSN. However, in the past two decades, the use of topical medications for OSSN treatment has gained a reputation amongst ophthalmologists for being an effective alternative to surgical excision. Furthermore, technological advancements, such as those seen in high-resolution optical coherence tomography (HR-OCT) for the anterior segment, have facilitated the diagnosis and monitoring of OSSN. When selecting a topical agent, interferon alpha-2b (IFNα-2b) and 5-fluorouracil (5-FU) are two of the gentlest medications used for OSSN and are often considered first line therapies due to their high-resolution rates and mild side effect profiles. Mitomycin C (MMC), on the other hand, has a highly toxic profile; therefore, while effective, in our hands it is considered as a second-line treatment for OSSN if the other modalities fail. In addition, newer and less studied agents, such as immune checkpoint inhibitors, retinoic acid, aloe vera, and anti-vascular endothelial growth factor have anti-neoplastic properties and have shown potential for the treatment of OSSN. We enclose an updated literature review of medical treatments for OSSN.

Mesoporous Silica Nanoparticles Coated with Carboxymethyl Chitosan for 5-Fluorouracil Ocular Delivery: Characterization, In Vitro and In Vivo Studies. Molecules 2023; 28:molecules28031260.

Abstract
This study investigates the development of topically applied non-invasive amino-functionalized silica nanoparticles (AMSN) and O-Carboxymethyl chitosan-coated AMSN (AMSN-CMC) for ocular delivery of 5-Fluorouracil (5-FU). Particle characterization was performed by the DLS technique (Zeta-Sizer), and structural morphology was examined by SEM and TEM. The drug encapsulation and loading were determined by the indirect method using HPLC. Physicochemical characterizations were performed by NMR, TGA, FTIR, and PXRD. In vitro release was conducted through a dialysis membrane in PBS (pH 7.4) using modified Vertical Franz diffusion cells. The mucoadhesion ability of the prepared nanoparticles was tested using the particle method by evaluating the change in zeta potential. The transcorneal permeabilities of 5-FU from AMNS-FU and AMSN-CMC-FU gel formulations were estimated through excised goat cornea and compared to that of 5-FU gel formulation. Eye irritation and ocular pharmacokinetic studies from gel formulations were evaluated in rabbit eyes. The optimum formulation of AMSN-CMC-FU was found to be nanoparticles with a particle size of 249.4 nm with a polydispersity of 0.429, encapsulation efficiency of 25.8 ± 5.8%, and drug loading capacity of 5.2 ± 1.2%. NMR spectra confirmed the coating of AMSN with the CMC layer. In addition, TGA, FTIR, and PXRD confirmed the drug loading inside the AMSN-CMC. Release profiles showed 100% of the drug was released from the 5-FU gel within 4 h, while AMSN-FU gel released 20.8% of the drug and AMSN-CMC-FU gel released around 55.6% after 4 h. AMSN-CMC-FU initially exhibited a 2.45-fold increase in transcorneal flux and apparent permeation of 5-FU compared to 5-FU gel, indicating a better corneal permeation. Higher bioavailability of AMSN-FU and AMSN-CMC-FU gel formulations was found compared to 5-FU gel in the ocular pharmacokinetic study with superior pharmacokinetics parameters of AMSN-CMC-FU gel. AMSN-CMC-FU showed 1.52- and 6.14-fold higher AUC0-inf in comparison to AMSN-FU and 5-FU gel, respectively. AMSN-CMC-FU gel and AMSN-FU gel were "minimally irritating" to rabbit eyes but showed minimal eye irritation potency in comparison to the 5 FU gel. Thus, the 5-FU loaded in AMSN-CMC gel could be used as a topical formulation for the treatment of ocular cancer.

Abstract
PURPOSE To determine the efficacy and safety of topical 1% 5-fluorouracil (5FU) eye drops as primary treatment of ocular surface squamous neoplasia (OSSN). METHODS Patients were diagnosed with OSSN based on slit-lamp examination and anterior segment optical coherence tomography (AS-OCT). In ambiguous cases an incisional biopsy was performed. All were treated with 5FU eye drops as primary therapy and retrospectively reviewed. Data on demographics, tumor characteristics, treatment outcome, and side effects were collected. The primary outcome measures were resolution frequency and recurrence rate of OSSN. Secondary outcomes were risk factors for resolution and recurrence, and side effects of treatment. RESULTS The mean age of 251 subjects (258 eyes) was 67.5 ± 11.7 years, 182 were male. Patients were followed up on average for 752 ± 580 days. Overall, 87% of patients experienced complete tumor resolution. Multivariable analysis revealed that superior tumor location (HR: 0.62, 95% CI: 0.41-0.93, p = 0.02) and leukoplakia (HR: 0.65, 95% CI: 0.41-0.93, p = 0.02), decreased the likelihood of tumor resolution. The recurrence rate was 4% at six months, 8% at one year, and 19% at two years. Larger tumor area increased chances of tumor recurrence (HR: 1.01, 95% CI: 1.00-1.02 p = 0.03). The most common side effects of 5-FU were mild hyperemia and pain, which occurred in 26% and 23% of patients, respectively. Among the sight-threatening side effects, limbal stem cell deficiency occurred in only 3% of patients. CONCLUSIONS Topical 1% 5FU eye drops are a safe and effective medication for OSSN. Superior tumor location and leukoplakia decreased the chance of tumor resolution.

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.

Yeoh CHY, Lee JJR, Lim BXH, Sundar G, Mehta JS, Chan ASY, Lim DKA, Watson SL, Honavar SG, Manotosh R, Lim CHL. The Management of Ocular Surface Squamous Neoplasia (OSSN). Int J Mol Sci 2022; 24:ijms24010713. [PMID: 36614155 PMCID: PMC9821412 DOI: 10.3390/ijms24010713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 12/24/2022] [Accepted: 12/28/2022] [Indexed: 01/03/2023] Open
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
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
Introduction This study evaluated the efficacy of combined interferon α-2b (IFNα2b) and 5-fluorouracil (5-FU) as primary treatment for ocular surface squamous neoplasia (OSSN). Methods In this retrospective study, 27 eyes with OSSN followed by topical application of combined IFNα2b and 5-FU were examined. Reported outcome measures were tumor response, visual acuity, time to complete resolution, recurrence and treatment complications. Results Twenty-six patients (17 male, 9 female) had a mean age of 63.9 (median, 67; range 22–83) years. Complete tumor response was observed in 24 eyes (88.9%). Three eyes (11.1%) showed partial response to the chemotherapy agents and later underwent surgical tumor removal. The median time to complete resolution was 6 (mean, 6.1; range, 3–11) weeks. Of these, the patients received between one to three cycles of 5-FU therapy (median, 2; mean, 1.8). Complications noted were transient irritation at 5-FU cycle (11 eyes, 40.7%). There was no tumor recurrence at mean follow-up of 16.1 (median, 12; range 6–38) months. Conclusions Combination therapy of IFNα2b and 5-FU was a safe and effective treatment, inducing a short duration of administration and low recurrence rate for OSSN. Trial Registration Retrospectively registered, UHCT22048.

Abstract
PURPOSE A retrospective population-based study to investigate racial and socioeconomic disparities in patients diagnosed with ocular surface squamous neoplasia (OSSN). METHODS To explore racial disparity, we selected OSSN patients with known age, insurance, gender and zip code-level income and education from the National Cancer Database (NCDB). Comparisons of clinical and socioeconomic variables stratified by race were made with the chi-square or Mann-Whitney tests. Survival outcome was examined a Cox regression model. RESULTS Of the 2,402 identified patients from 2004 to 2015, 117 were black. Unadjusted differences were found between groups in regard to age, histology, insurance, income, and education. Black patients in comparison to white patients were younger (mean age: 62 years vs. 70 years; p < .001), represented a higher proportion of Medicaid use (10.3% vs. 3.2%; p < .001) or uninsured (10.3% vs. 2.7%; p < .001), and were more likely to reside in areas of low educational attainment (32.5% vs. 16.1% of whites; p < .001). Multivariate analysis found significantly higher risk of death in patients who were male (HR: 1.66, 95% CI 1.37-2.01) or black (HR: 1.57, 95% CI 1.03-2.38). CONCLUSION Disparities in socioeconomic factors were observed in black patients with OSSN. OSSN occurred earlier in blacks, who were also socioeconomically disadvantaged and faced higher risk of death.

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
Mutations in the titin (TTN) gene are among the most common genomic aberrations in ocular surface squamous neoplasia (OSSN), the most common cancer of the external eye. Further, TTN mutations are associated with resistance to standard therapy with topical interferon alpha-2b (IFN-α2b). However, it remains unclear how TTN mutations drive OSSN pathogenesis and treatment resistance. TTN encodes the largest protein in the human body and its best understood function is as a myofibril scaffold in striated muscle. However, recent evidence indicates that TTN has additional functions in non-muscle cells and in cancer. Here, we performed a disorder-based bioinformatics analysis which revealed that intrinsically disordered protein regions are abundant in TTN and provide mechanistic insights into its function as a nuclear protein in epithelial cells. Specific mutations found in OSSN are predicted to affect its intrinsically disordered protein regions (IDPRs), promoting chromosomal instability, oncogenesis, and altered response to IFN-α2b treatment.

Abstract
PURPOSE To investigate the effects of mitomycin-C (MMC) and 5-fluorouracil (5-FU) on the viability, proliferation, and migratory capacity of cultured ocular adnexal sebaceous carcinoma (SC) cells. DESIGN Laboratory investigation. METHODS Human SC cell lines (Bascom Palmer 50 and 52 [BP50 and BP52]) and human limbal stem cells (LSCs) were treated with various concentrations of MMC and 5-FU. Cytotoxicity was assessed with the tetrazolium MTT colorimetric viability assay on normal corneal vs tumor cells. Growth curves and scratch assays were performed to characterize the effects of these chemotherapeutic agents on SC proliferation and migration, respectively. RESULTS MMC decreased BP52 cell viability in a dose-dependent manner with a half-maximal effective dose (EC50) of 11.8 μM after 72 hours. SC viability decreased >50% at 80 mM 5-FU after 72 hours. MMC reduced LSC viability in a dose-dependent manner with an EC50 value of 3.24 μM, and 5-FU decreased LSC viability >50% at 160 μM. MMC decreased SC cell proliferation and migration in a dose-dependent manner. 5-FU displayed antiproliferative effects but did not affect cell migration at concentrations below 1000 μM. CONCLUSIONS Our in vitro data corroborate clinical observations that MMC is efficacious for treating ocular adnexal SC, albeit at the expense of LSC viability. Our findings also demonstrate that topical 5-FU exhibits antiproliferative effects that supersede its cancer-killing and antimigratory effects on cultured SC cells.

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 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
The gold-standard treatment for ocular surface squamous neoplasia (OSSN) has traditionally been surgical excision with wide margins and a no-touch technique. However, surgery may be associated with several unfavourable sequelae, as well as significant recurrence rates if margins are positive. In recent years, topical chemotherapy with 5-fluorouracil, interferon α-2b and mitomycin C have emerged as valuable agents capable of effectively treating OSSN with varying adverse effects. These medical treatment options usually present additional costs to the patient but can allow patients to avoid surgery with fewer long-term effects. Anterior segment high-resolution optical coherence tomography is an excellent tool for diagnosing and monitoring OSSN and can be a useful aid for both surgical and medical treatments of OSSN.

Abstract
SIGNIFICANCE Ocular surface squamous neoplasias are superficial tumors of the cornea and conjunctiva that can be sight threatening if neglected. Therefore, accurate noninvasive diagnostic modalities are needed. PURPOSE The purpose of this case series was to describe the hallmark features of ocular surface squamous neoplasia on high-resolution optical coherence tomography (HR-OCT) imaging and its use in the evaluation and management of superficial ocular tumors. CASE SERIES Five eyes of four patients with ocular surface squamous neoplasia are described. Whereas two eyes displayed the classic clinical features of ocular surface squamous neoplasia, three of the five eyes had more subtle atypical features. However, all shared features on HR-OCT of epithelial thickening and hyperreflectivity with abrupt transitions between normal and abnormal tissue, classic features of ocular surface squamous neoplasia. All lesions ultimately underwent incisional or excisional biopsy and were confirmed to be ocular surface squamous neoplasia on histopathology. CONCLUSIONS Ocular surface squamous neoplasia may present as a classic tumor but can also have subtle features or masquerade. Accurate methods to diagnose and manage patients with ocular surface squamous neoplasia are necessary. With recent advancements in technology, HR-OCT has been demonstrated to accurately identify ocular surface squamous neoplasia with the repeatable optical findings of (1) epithelial thickening, (2) epithelial hyperreflectivity, and (3) abrupt transition zone between normal and abnormal tissue. This case series demonstrates how HR-OCT can help provide an optical biopsy to guide appropriate diagnosis and management of this neoplastic lesion.

Abstract
Ocular surface squamous neoplasia (OSSN) is the most common ocular tumour with an incidence ranging from 0.03 to 1.9 per 100,000 persons/year. The diagnosis is made on clinical suspicion and confirmed with anterior-segment optical coherence tomography (AS-OCT), cytology, or histology. The purpose of this review is to provide an overview of the management options available for OSSN and review their success and recurrence rates. Surgery is the gold standard for the management of small OSSN lesions. With the increased use of less invasive diagnostic modalities such as AS-OCT and cytology, there has been a move to use topical therapies for the management of OSSN. The most commonly used agents are interferon-α2b (IFN), mitomycin-C (MMC) and 5-fluorouracil (5FU). They have been shown to have similar resolution and recurrence rates but differ in cost and side effect profile. IFN has the lowest side effect profile, but is also the most expensive, whereas MMC has the greatest surface toxicity and is priced midway between the three. 5FU is the cheapest of the three topical agents with less surface toxicity than MMC. Radiotherapy is mostly employed as adjuvant therapy. Newer novel therapies are available but have not been widely adopted as mainstream therapy due to cost and lack of clinical evidence. OSSN has the benefit of many management options. No single modality has been shown to superior and some patients will need the use of combination therapy to achieve an optimal clinical outcome.

Abstract
Several neoplastic processes can involve the eye, either primarily or secondary to a systemic malignancy. The most common primary tumors of the eye include conjunctival and uveal melanoma, retinoblastoma, conjunctival and intraocular lymphoma, and ocular surface squamous neoplasia. Metastatic spread from systemic malignancies, especially of the breast and lung, also can involve the eye. A combination of ophthalmologic examination, ancillary testing, and cytologic/histopathologic evaluation leads to accurate diagnosis. Management consists of surgery, radiotherapy, chemotherapy, and immunotherapy delivered in various forms.

Abstract
A man with a history of blind eye due to trauma 22 years earlier consulted at 53 years of age with a large conjunctival neoplastic lesion, compromising almost the entire temporal limbus, and reaching a size of approximately 16 mm on its larger diameter, in the conjunctiva. Management was started with topical and subconjunctival chemotherapy (interferon alpha-2b) in order to perform immunoreduction, but a dramatic response with total disappearance of the lesion was observed. In the follow-up time period of more than 7 years, there were no signs of recurrence.

Single-Fraction Adjuvant Electronic Brachytherapy after Resection of Conjunctival Carcinoma. Cancers (Basel) 2021; 13:cancers13030454.

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.

Abstract
Approximately 45% of the human genome is composed of transposable elements (TEs). Expression of these elements is tightly regulated during normal development. TEs may be expressed at high levels in embryonic stem cells but are epigenetically silenced in terminally differentiated cells. As part of the global 'epigenetic dysregulation' that cells undergo during transformation from normal to cancer, TEs can lose epigenetic silencing and become transcribed, and, in some cases, active. Here, we summarize recent advances detailing the consequences of TE activation in cancer and describe how these understudied residents of our genome can both aid tumorigenesis and potentially be harnessed for anticancer therapies.

Abstract
Purpose To investigate the effectiveness and safety of subconjunctival/perilesional 5-fluorouracil injections on ocular surface squamous neoplasia (OSSN) during a 3-year follow-up period. Patients and Methods We followed up six patients with intraepithelial OSSN (in one eye each) that had regressed after subconjunctival/perilesional 5-fluorouracil injections. Conjunctival fluorescein angiography (FA) and indocyanine green angiography (ICGA), as well as anterior segment optical coherence tomography (AS-OCT), were performed to evaluate the OSSN status 3 years after initiation of treatment. Results The mean age of patients (five males, one female) at baseline was 62.3±11.6 years. The mean number of 5-fluorouracil injections was 17.0±8.6, with a mean treatment duration of 13.0±7.4 weeks. At the final visit, both intratumoral and conjunctival feeding vessels had disappeared on ICGA and FA, with no neovascularization-related leakage, in accordance with the results of AS-OCT. The period from complete tumor regression to final visit according to AS-OCT was 32.5±4.2 months, which was longer than that according to ICGA (31.3±3.2 months, p=0.034). The final best-corrected visual acuity was similar to that at baseline (p=0.128). No side effects were observed in any of the eyes. Conclusion Subconjunctival/perilesional 5-fluorouracil injections are an effective and safe treatment for OSSN. Future studies with a larger sample size are warranted for confirmation of our findings, as well as investigation into the reasons for residual areas of non-perfusion in the conjunctiva.

Abstract
Local chemotherapy is increasingly used, either in combination with surgery or as monotherapy, for management of ocular tumors. Yet many of the local chemotherapeutic agents used for ocular tumors are cytotoxic drugs that are frequently associated with toxicities in normal ocular tissues. Understanding and managing these side effects are important because they affect treatment tolerability, outcome and quality of vision. Herein, we review local anticancer drugs administered for the treatment of ocular tumors, with an emphasis on their toxicities to the ocular surface, adnexa and lacrimal drainage system. We provide the underlying mechanisms and management strategies for the ocular side effects. Recent innovations in anticancer immunotherapy and ocular drug delivery systems also are discussed as new potential therapeutic modalities for alleviation of side effects.

Abstract
A 73-year-old-gentleman was referred for ocular surface squamous neoplasia (OSSN) in his right eye (RE). He had history of combined cataract with trabeculectomy in RE and was maintaining his intraocular pressure (IOP). He showed a corneoscleral lesion measuring 11 × 8 mm in nasal quadrant wherein, the superior edge of the lesion was extending up to the filtering bleb. After ruling out intraocular invasion or regional spread, he underwent complete tumor excision with “no touch” technique along with cryotherapy and surface reconstruction and a perilesional injection of Interferon α2B. At 6-month visit, he shows no locoregional recurrence and has controlled IOP.

Abstract
Background New York City has a heterogeneous population with many undocumented and uninsured immigrants from equatorial areas who have a higher incidence of ocular surface squamous neoplasia. To the best of our knowledge, this is the first documented selection of this cost-effective treatment of ocular surface squamous neoplasia (the use of absolute ethanol along the corneal margin, primary excision, double freeze-thaw cryopexy, and primary conjunctival closure) for an undocumented and uninsured New York City patient. Case presentation A 35-year-old man from Ecuador presented to a New York City emergency department due to worsening discomfort of a long-standing left eye pterygium. A slit-lamp examination of the left eye demonstrated a nasally located conjunctival mass measuring 6 × 8 mm extending onto the cornea (3 mm superiorly and 6 mm inferiorly on the cornea). Histological diagnosis confirmed squamous cell carcinoma in situ arising from the pterygium. Surgical excision with adjunctive absolute alcohol with additive double freeze-thaw cryopexy was performed. Our patient has remained free of tumor recurrence at year 2 postoperative visit. Conclusions Our case highlights the need to choose a cost-effective treatment for ocular surface squamous neoplasia in an at-risk population among undocumented and uninsured patients. Areas in the world with similar types of populations or treatment challenges may need to consider this approach as a primary treatment option.

Abstract
PURPOSE To report a case of a large conjunctival melanoma (CM) successfully treated with surgical resection and pre- and postoperative topical mitomycin C (MMC). METHODS This is a single observational case report. RESULTS A 58-year-old man was referred to us for a large pigmented conjunctival lesion of the right eye. Slit lamp examination revealed an extensive pigmented lesion diffusely involving the temporal bulbar conjunctiva, with multifocal intensely dark areas and an elevated limbal component extending on the corneal surface. The remaining bulbar and forniceal conjunctiva was not involved. The lesion was clinically diagnosed as CM. Clinical examination and head and neck ultrasonography did not show regional lymphadenopathy. The patient was treated with neoadjuvant topical MMC 0.04% four times a day for 3 weeks. At the end of MMC therapy we observed a reduction in pigmentation and thickness of the lesion. Subsequently, the patient underwent surgical excision of the lesion with "no touch technique," double freeze-thaw cryotherapy of the margins and reconstruction of the tissue defect with amniotic membrane graft. Histopathologic examination of the specimen confirmed the presence of CM, surrounded by primary acquired melanosis with atypia. The excision margins were positive for tumor involvement, so we decided to perform an adjuvant treatment with other four cycles of topical MMC. CONCLUSIONS The patient was closely followed-up after the treatment, without any local or distant recurrence at 32 months.
