RESUMO

BACKGROUND: Molecular testing with gene-expression profiling (GEP) and donor-derived cell-free DNA (dd-cfDNA) is increasingly used in the surveillance for acute cellular rejection (ACR) after heart transplant. However, the performance of dual testing over each test individually has not been established. Further, the impact of dual noninvasive surveillance on clinical decision-making has not been widely investigated. METHODS: We evaluated 2,077 subjects from the Surveillance HeartCare Outcomes Registry registry who were enrolled between 2018 and 2021 and had verified biopsy data and were categorized as dual negative, GEP positive/dd-cfDNA negative, GEP negative/dd-cfDNA positive, or dual positive. The incidence of ACR and follow-up testing rates for each group were evaluated. Positive likelihood ratios (LRs+) were calculated, and biopsy rates over time were analyzed. RESULTS: The incidence of ACR was 1.5% for dual negative, 1.9% for GEP positive/dd-cfDNA negative, 4.3% for GEP negative/dd-cfDNA positive, and 9.2% for dual-positive groups. Follow-up biopsies were performed after 8.8% for dual negative, 14.2% for GEP positive/dd-cfDNA negative, 22.8% for GEP negative/dd-cfDNA positive, and 35.4% for dual-positive results. The LR+ for ACR was 1.37, 2.91, and 3.90 for GEP positive, dd-cfDNA positive, and dual-positive testing, respectively. From 2018 to 2021, biopsies performed between 2 and 12-months post-transplant declined from 5.9 to 5.3 biopsies/patient, and second-year biopsy rates declined from 1.5 to 0.9 biopsies/patient. At 2 years, survival was 94.9%, and only 2.7% had graft dysfunction. CONCLUSIONS: Dual molecular testing demonstrated improved performance for ACR surveillance compared to single molecular testing. The use of dual noninvasive testing was associated with lower biopsy rates over time, excellent survival, and low incidence of graft dysfunction.

RESUMO

BACKGROUND: The quality-adjusted life year (QALY) measures disease burden and treatment, combining overall survival and health-related quality of life (HRQOL). We estimated QALYs in 3 groups of older patients (60-80 years) with heart failure (HF) who underwent heart transplantation (HT, with pre-transplant mechanical circulatory support [HT MCS] or HT without pre-transplant MCS [HT Non-MCS]) or long-term MCS (destination therapy). We also identified factors associated with gains in QALYs through 24 months follow-up. METHODS: Of 393 eligible patients enrolled (10/1/15-12/31/18) at 13 U.S. sites, 161 underwent HT (n = 68 HT MCS, n = 93 HT Non-MCS) and 144 underwent long-term MCS. Survival and HRQOL data were collected through 24 months. QALY health utilities were based on patient self-report of EQ-5D-3L dimensions. Mean-restricted QALYs were compared among groups using generalized linear models. RESULTS: For the entire cohort, mean age in years closest to surgery was 67 (standard deviation, SD: 4.7), 78% were male, and 83% were White. By 18 months post-surgery, sustained significant differences in adjusted average ± SD QALYs emerged across groups, with the HT Non-MCS group having the highest average QALYs (24-month window: HT Non-MCS = 22.58 ± 1.1, HT MCS = 19.53 ± 1.33, Long-term MCS = 19.49 ± 1.3, p = 0.003). At 24 months post-operatively, a lower gain in QALYs was associated with HT MCS, long-term MCS, a lower pre-operative LVEF, NYHA class III or IV before surgery, and an ischemic or other etiology of HF. CONCLUSIONS: Determination of QALYs may provide important information for policy makers and clinicians to consider regarding benefits of HT and long-term MCS as treatment options for older patients with HF.

RESUMO

BACKGROUND: Information about health-related quality of life (HRQOL) among caregivers of older patients with heart failure who receive heart transplantation (HT) and mechanical circulatory support (MCS) is sparse. We describe differences and factors associated with change in HRQOL before and early post-surgery among caregivers of older heart failure patients who underwent 3 surgical therapies: HT with pretransplant MCS (HT MCS), HT without pretransplant MCS (HT non-MCS), and long-term MCS. METHODS: Caregivers of older patients (60-80 years) from 13 US sites completed the EQ-5D-3 L visual analog scale (0 [worst]-100 [best] imaginable health state) and dimensions before and 3 and 6 months post-surgery. Analyses included linear regression, t tests, and nonparametric tests. RESULTS: Among 227 caregivers (HT MCS=54, HT non-MCS=76, long-term MCS=97; median age 62.7 years, 30% male, 84% White, 83% spouse/partner), EQ-5D visual analog scale scores were high before (84.8±14.1) and at 3 (84.7±13.0) and 6 (83.9±14.7) months post-surgery, without significant differences among groups or changes over time. Patient pulmonary hypertension presurgery (ß=-13.72 [95% CI, -21.07 to -6.36]; P<0.001) and arrhythmia from 3 to 6 months post-operatively (ß=-14.22 [95% CI, -27.41 to -1.02]; P=0.035) were associated with the largest decrements in caregiver HRQOL; patient marital/partner status (ß=6.21 [95% CI, 1.34-11.08]; P=0.013) and presurgery coronary disease (ß=8.98 [95% CI, 4.07-13.89]; P<0.001) were associated with the largest improvements. CONCLUSIONS: Caregivers of older patients undergoing heart failure surgeries reported overall high HRQOL before and early post-surgery. Understanding factors associated with caregiver HRQOL may inform decision-making and support needs. REGISTRATION: URL: https://www. CLINICALTRIALS: gov; Unique identifier: NCT02568930.

RESUMO

Fusarium species manifests as an opportunistic infection with intrinsic resistance to most antifungals. We present a case of a 63-year-old male with myelodysplasia who received allogeneic stem cell transplantation and presented with endophthalmitis as the initial manifestation of invasive fusariosis that progressed to a fatal outcome despite combined intravitreal and systemic antifungal therapies. We urge clinicians to consider this complication of fusarium infection especially with the widespread use of antifungal prophylaxis that may incur selection of more resistant, invasive fungal species.

RESUMO

Purpose: The purpose of this first in-human study was to evaluate the overall clinical performance of the VERITAS™ Vision System in patients scheduled to undergo cataract extraction and to confirm overall surgeon acceptability. Patients and methods: This prospective, open-label multinational study included adults with cataracts scheduled for planned cataract extraction and posterior chamber IOL implantation. Standard small-incision phacoemulsification cataract surgery with the VERITAS Vision System was conducted. Surgeons completed a questionnaire regarding their clinical experience with the VERITAS Vision System for each patient following surgery and 1-day postoperative. Corneal clarity and adverse events (AEs) were assessed. Surgeon acceptability was scored on a 5-point scale, with acceptability considered favorable for scores of 4 and 5. Results: A total of 115 eyes (79 patients) were treated. The El Salvador site treated 41 patients (58 eyes), and the US site treated 38 patients (57 eyes). Overall, surgeons were satisfied with the clinical performance regardless of the cataract grade. The satisfaction with anterior chamber stability, post-occlusion surge, followability, holdability, cutting efficiency, usability, and overall satisfaction with the VERITAS Vision System was clinically favorable in ≥99% of cases. Overall satisfaction with the swivel handpiece, foot pedal, and enhanced ergonomics were clinically favorable in ≥97% of cases regardless of the cataract grade. Satisfaction with corneal clarity at same-day postoperative and 1-day postoperative, and 1-day overall clinical results of surgery with the VERITAS Vision System were clinically favorable in ≥94% of cases regardless of cataract grade. Conclusion: The new dual-mode phacoemulsification system with dual-durometer tubing, gas forced infusion, new swivel handpiece, and ergonomics improvements resulted in a high rate of user satisfaction with clinical performance and ergonomics. The VERITAS Vision System is safe and effective when used as indicated.

RESUMO

Nevoid and myxoid melanoma are rare variants of melanoma; association of the two is a unique finding. Nevoid melanoma is characterized by morphologic resemblance to a nevus, whereas myxoid melanoma demonstrates a basophilic mucinous matrix. We present an atypical case of a melanoma progressing from a nevoid melanocytoma with myxoid changes. A 78-year-old female presented with a pigmented growth on her right thigh. Biopsy demonstrated a biphenotypic melanocytic proliferation composed of a nodule showing epithelioid melanocytes with enlarged nuclei, prominent nucleoli, lack of maturation, and abundant amphophilic cytoplasm with a rare mitotic figure. These findings were suggestive of melanoma along with a nevoid dermal component and myxoid stroma. FISH testing revealed a homozygous loss of 9p21 in the atypical component. SNP-microarray from the nevoid component demonstrated three abnormalities including a gain of whole chromosome 8, as well as loss of a copy of nearly an entire chromosome 9 and 16q most consistent with a melanocytoma.

RESUMO

Le Fort fractures occur at uniform weak areas in the midface often due to blunt impact to the face. Sporting injuries are a common cause of facial trauma; however, use of protective equipment has reduced the number of sports-related injuries. All patients with traumatic injuries should be evaluated using Advanced Trauma Life Support protocol. Le Fort fractures can contribute to airway obstruction, and urgent intubation may be indicated. Surgery is indicated for most displaced Le Fort fractures to restore function and facial harmony. To facilitate reduction, the original occlusive relationship should be restored by placing the patient in MMF.

RESUMO

BACKGROUND: Gene expression profiling (GEP) and donor-derived cell-free DNA (dd-cfDNA) are useful in acute rejection (AR) surveillance in orthotopic heart transplant (OHT) patients. We report a single-center experience of combined GEP and dd-cfDNA testing for AR surveillance. METHODS: GEP and dd-cfDNA are tested together starting at 2 months post-OHT. After 6 months, combined testing was obtained before scheduled endomyocardial biopsy (EMB), and EMB was canceled with a negative dd-cfDNA. This approach was compared to using a GEP-only approach, where EMB was canceled with a negative GEP. We evaluated for frequency of EMB cancellation with dd-cfDNA usage. RESULTS: A total of 153 OHT patients over a 13-month period underwent 495 combined GEP/dd-cfDNA tests. 82.2% of dd-cfDNA tests were below threshold. Above threshold results identified high-risk patients who developed AR. 378 combined tests ≥6 months post-OHT resulted in cancellation of 83.9% EMBs as opposed to 71.2% with GEP surveillance alone. There were 2 acute cellular and 2 antibody-mediated rejection episodes, and no significant AR ≥6 months. CONCLUSION: Routine dd-cfDNA testing alongside GEP testing yielded a significant reduction in EMB volume by re-classifying GEP (+) patients into a lower risk group, without reduction in AR detection. The addition of dd-cfDNA identified patients at higher risk for AR.

RESUMO

PURPOSE: To report a case of metastatic cutaneous melanoma presenting with choroidal metastasis simulating primary uveal melanoma. DESIGN: Case report. METHOD: Presentation of clinical, radiographic, histopathologic, and tumor genetic findings in a patient with cutaneous melanoma with choroidal metastasis. RESULTS: A 50-year-old man with a remote history of stage 1A cutaneous melanoma presented with eye pain, peripheral vision loss, floaters, red eye, and choroidal mass that was originally diagnosed as a primary uveal melanoma at an outside institution; however, subsequent imaging and clinical evaluation demonstrated that this choroidal mass was the first manifestation of widely metastatic cutaneous melanoma (liver, pancreas, lung, bone, brain, and orbit lesions). Histopathologic analysis of the tumor after enucleation was consistent with cutaneous melanoma, and tumor genetic testing was positive for BRAF V600E mutation, confirming the choroidal lesion to be a cutaneous melanoma metastasis rather than a primary choroidal melanoma. CONCLUSIONS: Metastatic cutaneous melanoma to the orbit or globe occurs rarely. Tumor genetic testing may help differentiate metastatic cutaneous melanoma from primary uveal melanoma in cases where the diagnosis is uncertain, and can also inform therapy and prognostic counseling.

RESUMO

Standardized donor-derived cell-free DNA (dd-cfDNA) testing has been introduced into clinical use to monitor kidney transplant recipients for rejection. This report describes the performance of this dd-cfDNA assay to detect allograft rejection in samples from heart transplant (HT) recipients undergoing surveillance monitoring across the United States. Venous blood was longitudinally sampled from 740 HT recipients from 26 centers and in a single-center cohort of 33 patients at high risk for antibody-mediated rejection (AMR). Plasma dd-cfDNA was quantified by using targeted amplification and sequencing of a single nucleotide polymorphism panel. The dd-cfDNA levels were correlated to paired events of biopsy-based diagnosis of rejection. The median dd-cfDNA was 0.07% in reference HT recipients (2164 samples) and 0.17% in samples classified as acute rejection (35 samples; P = .005). At a 0.2% threshold, dd-cfDNA had a 44% sensitivity to detect rejection and a 97% negative predictive value. In the cohort at risk for AMR (11 samples), dd-cfDNA levels were elevated 3-fold in AMR compared with patients without AMR (99 samples, P = .004). The standardized dd-cfDNA test identified acute rejection in samples from a broad population of HT recipients. The reported test performance characteristics will guide the next stage of clinical utility studies of the dd-cfDNA assay.

RESUMO

BACKGROUND/AIMS: To report the case of a 77-year-old male with a blind, painful eye, referred for suspected corneal mass, with finding of choroidal B-cell lymphoma on pathology of enucleated globe. METHODS: This is a retrospective case report of a single patient. RESULTS: A 77-year-old male with a longstanding history of poor vision in the left eye was referred for a scarred, vascularized corneal mass. The patient had reported occasional mild ocular discomfort in the left eye and loss of light perception over the last year. Visual acuity was 20/20 in the right eye and no light perception in the left eye. Intraocular pressure was 32 mm Hg in the left eye. Fundoscopic visualization was not possible due to corneal opacity. B-scan ultrasound showed an infiltrative, low-reflective choroidal lesion and inferior retinal detachment. Pathology from the enucleated globe revealed diffuse sheets of CD20+ small B cells replacing the choroid, characteristic of a low-grade small B-cell extranodal marginal zone lymphoma. CONCLUSION: This is an unusual presentation of choroidal lymphoma in an eye with severe corneal opacification and scarring, and underscores the diagnostic value of ultrasonography in examination of eyes without view to the posterior segment.

RESUMO

Background and purpose The purpose of this article is to estimate the distribution of superselective intra-arterial chemotherapy (IAC) delivery to ocular target tissue using quantitative digital subtraction angiography (qDSA). Materials and methods From March 2010 to January 2016, 50 ophthalmic artery contrast DSAs obtained immediately prior to IAC infusions in 22 patients were analyzed. This study was conducted under a retrospective review IRB (no. 10-01862). Parametric color-coded DSAs (iFlow, Siemens Medical) were post-processed (MATLAB, The Mathworks Inc.) using two methods: two box regions of interest (pre-retina and globe) and four custom regions of interest (ROIs-ophthalmic artery, choroid, supraclinoid internal carotid artery (ICA), cavernous ICA). Mean interobserver reliability of custom ROI selection is presented as a 95% confidence interval of interclass correlation, and fractional chemotherapy delivery to selected ROIs as means ± standard deviation in this study. Results The estimated fraction of chemotherapy delivered to the globe with the first method was 79.5%. Percentage regional delivery using the second method was as follows: ophthalmic artery, 85.8%; choroid, 60.5%; supraclinoid ICA, 14.2%. The cavernous ICA ROI (encompassing distal catheter and potential reflux) gave a signal equivalent to 9.3% of total delivery. Conclusion Parametric color-coded qDSA can estimate the fraction of IAC delivered to the retina and other orbital structures in ocular retinoblastoma patients. This information can inform delivery location and dosing strategies on a patient-specific basis.

RESUMO

BACKGROUND: The management of conjunctival melanoma is difficult because of the rarity of the disease, confusing terminology, high rates of local tumor recurrence, controversies regarding treatment, a poor evidence base, unreliable prognostication, and significant mortality rates. METHODS: The medical literature was reviewed, focusing on treatment and management options for conjunctival melanoma. Recent trends and developments were summarized with respect to terminology, local treatment, histology, genetic analysis, prognostication, and systemic treatment, highlighting the scope for research and possible improvements in patient care. RESULTS: Histopathological diagnostic terminology for primary acquired melanosis is being superseded by more explicit terminology, thus differentiating hypermelanosis from conjunctival melanocytic intraepithelial neoplasia. Topical chemotherapy and increased use of adjunctive radiotherapy have helped improve rates of local tumor control. Use of exenteration has become rare. Regional and systemic metastases are common in patients with nonbulbar conjunctival melanoma, although long-term survivors with metastases are growing in number. Prognostication is mainly based on tumor size and location, but histological and genetic data into multivariate analyses will soon be incorporated. The role of sentinel lymph-node biopsy continues to be controversial. Chemotherapy for metastatic disease is being superseded by targeted therapy based on genetic abnormalities such as BRAF mutations. CONCLUSIONS: The management of conjunctival melanoma requires expert care from an experienced, multidisciplinary team. The goal of therapy is to provide good local tumor control with minimal morbidity, high-quality pathology, and adequate psychological support. Maximizing patient enrollment in multicenter clinical trials is likely to strengthen evidence-based decision-making.

RESUMO

PURPOSE: To describe 7 patients with paraproteinemic keratopathy and to highlight the clinical and pathologic diversity of this rare entity and the importance of timely, systemic evaluation. DESIGN: Retrospective, multicenter collaborative case series. PARTICIPANTS: Seven patients with paraproteinemic keratopathy. METHODS: Clinical and pathologic records were reviewed to identify patients with well-documented corneal immunoglobulin deposits. Detailed ophthalmologic and medical histories were assembled. In 6 patients, corneal tissue was evaluated histochemically and immunohistochemically; in selected cases, corneal tissue was evaluated by in situ hybridization and ultrastructurally. MAIN OUTCOME MEASURES: Visual acuity and anterior segment examination at presentation and follow-up; local therapy; systemic diagnosis and management; and histopathologic, immunohistochemical, in situ hybridization, and ultrastructural findings. RESULTS: Seven patients were identified with corneal immunoglobulin deposition. In addition to previously reported crystalline, nummular, patch-like, and lattice-like corneal opacities, prominent corneal vascularization was present in 2 patients mimicking interstitial keratitis and limbal stem cell deficiency. All patients had evidence of paraproteinemia in a setting of monoclonal gammopathy of undetermined significance, smoldering plasma cell myeloma, or Waldenström macroglobulinemia. Corneal findings were the first manifestation of systemic disease in 4 patients, and the diagnosis was not suspected in 3 of these patients. Pathologic evaluation of biopsied corneal and conjunctival tissues demonstrated immunoglobulin deposits. Previously unreported ultrastructural patterns in the cornea were noted: large scroll-like immunotactoid deposits, immune complex-like deposits, and randomly arranged fibrils morphologically intermediate between amyloid and immunotactoid deposits. Surgical intervention to improve vision was performed in 4 patients, with recurrence of deposits in 3 patients. Three patients underwent systemic therapy with diminution of the deposits and improvement in vision in 1 patient. CONCLUSIONS: The clinical and pathologic expressions of corneal immunoglobulin deposits are protean and present a diagnostic challenge. Early recognition of this rare entity is important to address the potentially serious associated systemic disease.

RESUMO

BACKGROUND: Gene expression profiling test scores have primarily been used to identify heart transplant recipients who have a low probability of rejection at the time of surveillance testing. We hypothesized that the variability of gene expression profiling test scores within a patient may predict risk of future events of allograft dysfunction or death. METHOD: Patients from the IMAGE study with rejection surveillance gene expression profiling tests performed at 1- to 6-month intervals were selected for this cohort study. Gene expression profiling score variability was defined as the standard deviation of an individual's cumulative test scores. Gene expression profiling ordinal score (range, 0-39), threshold score (binary value=1 if ordinal score ≥ 34), and score variability were studied in multivariate Cox regression models to predict future clinical events. RESULTS: Race, age at time of transplantation, and time posttransplantation were significantly associated with future events in the univariate analysis. In the multivariate analyses, gene expression profiling score variability, but not ordinal scores or scores over threshold, was independently associated with future clinical events. The regression coefficient P values were <0.001, 0.46, and 0.773, for gene expression profiling variability, ordinal, and threshold scores, respectively. The hazard ratio for a 1 unit increase in variability was 1.76 (95% CI, 1.4-2.3). DISCUSSION: The variability of a heart recipient's gene expression profiling test scores over time may provide prognostic utility. This information is independent of the probability of acute cellular rejection at the time of testing that is rendered from a single ordinal gene-expression profiling test score.

RESUMO

PURPOSE: To report Achromobacter xylosoxidans as a cause of both acute-onset and delayed-onset postoperative endophthalmitis after cataract surgery. METHODS: A noncomparative consecutive case series of patients with culture-proven A. xylosoxidans endophthalmitis between 1970 and 2012. Cataract surgery and intraocular lens placement were performed in all patients before endophthalmitis. Positive cultures were obtained from the vitreous, capsular bag, and/or the removed intraocular lens. RESULTS: The clinical diagnosis was confirmed in four patients with positive cultures. Two patients with endophthalmitis had a preliminary culture report of Pseudomonas species. In addition to receiving intravitreal antibiotics, all patients underwent capsulectomy and intraocular lens removal at the time of pars plana vitrectomy. Visual acuity at last follow-up was 20/40 or better in 2 (50%) of the 4 patients, but the remaining 2 patients were 20/200 or worse. CONCLUSION: A. xylosoxidans may be a cause of acute, recurrent, and delayed-onset postoperative endophthalmitis after cataract surgery. Complete capsulectomy and intraocular lens removal can be considered in recurrent and recalcitrant patients.

RESUMO

PURPOSE: To assess the use of ultra-high-resolution (UHR) optical coherence tomography (OCT) in the diagnosis of ocular surface lesions. DESIGN: Prospective, noncomparative, interventional case series. PARTICIPANTS: Fifty-four eyes of 53 consecutive patients with biopsy-proven ocular surface lesions: 8 primary acquired melanosis lesions, 5 amelanotic melanoma lesions, 2 nevi, 19 ocular surface squamous neoplasia lesions, 1 histiocytosis lesion, 6 conjunctival lymphoma lesions, 2 conjunctival amyloidosis lesions, and 11 pterygia lesions. INTERVENTION: Ultra-high-resolution OCT imaging of the ocular surface lesions. MAIN OUTCOME MEASURES: Clinical course and photographs, UHR OCT image, and histopathologic findings. RESULTS: Ultra-high-resolution OCT images of all examined ocular surface lesions showed close correlation with the obtained histopathologic specimens. When clinical differential diagnosis of ocular surface lesions was broad, UHR OCT images provided optical signs indicating a more specific diagnosis and management. In cases of amelanotic melanoma, conjunctival amyloidosis, and primary histiocytosis and in 1 case of ocular surface squamous neoplasia, UHR OCT was instrumental in guiding the diagnosis. In those cases, UHR OCT suggested that the presumed clinical diagnosis was incorrect and favored a diagnosis that later was confirmed by histopathologic examination. CONCLUSIONS: Correlations between UHR OCT and histopathologic findings confirm that UHR OCT is an adjunctive diagnostic method that can provide a noninvasive means to help guide diagnosis and management of ocular surface lesions.

RESUMO

PURPOSE: The purpose of this study was to determine the prevalence of ocular surface squamous neoplasia (OSSN) coexisting with pterygia in South Florida and to study the treatment and related outcomes. DESIGN: Noninterventional retrospective study. PARTICIPANTS: A total of 2005 patients with surgically excised pterygia at the Bascom Palmer Eye Institute from 2000 to 2010. METHODS: Pathology reports of patients with pterygia were reviewed for evidence of OSSN. Patients were divided into the following groups: pterygium and no OSSN (group 1), clinically suspected OSSN with pterygium (group 2), and unexpected OSSN with pterygium found on histopathology (group 3). Clinical charts of patients in groups 2 and 3 were reviewed. MAIN OUTCOME MEASURES: Period prevalence, treatment, and outcome. RESULTS: In surgically excised pterygia, the prevalence of coexistent OSSN was 1.7% (n = 34), of which 41% (n = 14) were clinically suspected preoperatively (group 2) and 59% (n = 20) were unexpectedly found on histopathology (group 3). Clinically suspected OSSN with pterygia was generally treated with wide surgical margins and cryotherapy, whereas unexpected OSSN with pterygia was treated with simple excision, followed by adjuvant interferon treatment in 30% (n = 6). After a mean follow-up of 2 years, there were no recurrences in the suspected OSSN group and 2 recurrences in the unexpected OSSN group. The recurrence rate in the latter group was 11% at 1 year and 24% at 2 years. CONCLUSIONS: Ocular surface squamous neoplasia is uncommonly found to coexist with pterygium. The prognosis in suspected OSSN cases is excellent, with no recurrences noted despite positive margins in 50% of cases. The recurrence rates of unexpected OSSN mirrors that of OSSN not associated with pterygium, and thus vigilance for recurrence is important.

RESUMO

PURPOSE: To describe the clinical and histologic characteristics of ocular surface squamous neoplasia (OSSN) lesions and provide clinicopathologic correlation to determine clinical features that may indicate higher-grade lesions. DESIGN: Retrospective case series. PARTICIPANTS: A total of 612 consecutive OSSN lesions sent to the Bascom Palmer ocular pathology laboratory from January 1, 2001 to September 20, 2010. METHODS: Pathologic examination of lesions by a single experienced ocular pathologist (S.R.D.). Review of pathology records and patient charts. MAIN OUTCOME MEASURES: Correlation of clinical factors and histology of higher-grade OSSN. RESULTS: Over the studied period, 33% of submitted specimens were characterized as mild, moderate, or severe dysplasia; 52% were classified as carcinoma in situ; and 11% were graded as squamous cell carcinoma. Characteristics associated with higher-grade OSSN lesions included male gender, biopsy at Bascom Palmer Eye Institute, temporal and superior locations, lack of corneal involvement, papillomatous and nodular appearance, microscopic multifocality, and positive margins on biopsy. CONCLUSIONS: Certain clinical factors are associated with higher-grade histologic lesions. These findings may help clinicians more accurately evaluate and anticipate the pathologic grade of conjunctival and corneal lesions suspected to be OSSN.

RESUMO

PURPOSE: To identify predictors of ocular surface squamous neoplasm (OSSN) recurrence after operative resection. DESIGN: Retrospective case series. PARTICIPANTS: Three hundred eighty-nine consecutive patients who underwent excisional biopsy for OSSN lesions at the Bascom Palmer Eye Institute from January 1, 2001, to September 20, 2010. METHODS: Review of pathology records and patient charts. MAIN OUTCOME MEASURES: Identification of factors predictive of OSSN recurrence. RESULTS: Of 389 excised OSSN lesions, 44 recurred during follow-up. The 1-year recurrence rate was 10% and the 5-year recurrence rate was 21%, with a mean time to recurrence in those with a recurrence of 2.5 years (standard deviation, 3.4). Using the American Joint Committee on Cancer (AJCC) clinical staging system, T3 and T2 lesions portended a higher risk of recurrence compared with T1 (T2/T1 hazard ratio [HR], 2.05 [P = 0.04]; T3/T1 HR, 2.31 [P = 0.07]). In addition, a location characteristic that increased the risk of tumor recurrence was tarsal involvement (AJCC T3 stage lesion; HR, 4.12; P = 0.007). Nasal location was associated with a decreased risk of tumor recurrence (HR, 0.41; P = 0.008). Pathologic characteristics significantly associated with tumor recurrence were the presence of positive margins (HR, 2.73; P = 0.008) and higher grade lesions (carcinoma in situ and squamous cell carcinoma versus dysplasia; HR, 2.55; P = 0.02). Treatment with adjuvant cryotherapy significantly decreased the risk of tumor recurrence (HR, 0.51; P = 0.03). In those patients with positive margins, the use of postoperative topical interferon therapy lowered the recurrence rate to a level similar to that of patients with negative margins. CONCLUSIONS: Certain patient and tumor factors are associated with a higher risk of OSSN recurrence after operative excision, such as tarsal tumor location and positive surgical margins. Postoperative adjuvant therapy should be considered in patients with high-risk OSSN characteristics.
