Plaque brachytherapy is an effective eye and vision-sparing method to treat patients with intraocular tumors. Practitioners are encouraged to use ABS-OOTF guidelines to enhance their practice.

The AJCC Ophthalmic Oncology Task Force IMPORTANCE Although an accurate uveal melanoma staging system is needed to improve research and patient care, the evaluation of eye cancer staging systems requires international multicenter data sharing to acquire a statistically significant analysis. OBJECTIVE To assess patient mortality outcomes associated with uveal melanoma staging according to the 7th edition of the American Joint Committee on Cancer's AJCC Cancer Staging Manual. DESIGN, SETTING, PARTICIPANTS A committee was formed to create patient-specific data fields for patients with uveal melanoma. Ten subspecialty ophthalmic oncology centers from 4 continents shared data. Patient selection criteria included diagnosis of uveal melanoma from April 1, 2001, to April 1, 2011, adequate records to allow tumor staging by the AJCC criteria, and follow-up for metastatic melanoma. INTERVENTIONS Primary treatments included local resection, radiation therapy, and enucleation. MAIN OUTCOMES AND MEASURES Metastasis after initial tumor staging with 5-and 10-year Kaplan-Meier metastasis-free point estimates, depending on AJCC prognostic stages I through IV, tumor size category, and subclassification (defined by the presence of ciliary body involvement and/or extrascleral extension). RESULTS A total of 3809 patients were entered into the database. Of these, 3377 records (88.7%) were complete. Primary ciliary body and choroidal melanoma was the diagnosis for 3217, and 160 had primary iris melanoma. Tumor size categories were T1 in 1115 (34.7%) of the 3217 patients, T2 in 1128 patients (35.1%), T3 in 789 patients (24.5%), and T4 in 185 patients (5.8%). The 5-and 10-year Kaplan-Meier metastasis-free point estimates by tumor size categories were 97% (95% CI, 95%-98%) and 94% (95% CI, 91%-96%) for T1 tumors, 85% (95% CI, 82%-88%) and 80% (95% CI, 75%-84%) for T2 tumors, 77% (95% CI, 73%-80%) and 68% (95% CI, 60%-74%) for T3 tumors, and 61% (95% CI, 49%-71%) (5-year only) for T4 tumors, respectively. Increasing tumor size was consistent with increased metastasis risk (P < .001). Subclassifications were significantly associated with increased risk of metastasis (P < .001). The AJCC prognostic and anatomical groupings were as follows: stage I, 1030 (32.0%); stage IIA, 1095 (34.0%); stage IIB, 710 (22.1%); stage IIIA, 282 (8.8%); stage IIIB, 79 (2.5%); and stage IIIC, 21 (0.7%). The 5-and 10-year Kaplan-Meier metastasis-free estimates for prognostic stages were 97% (95% CI, 95%-98%) and 94% (95% CI, 91%-96%) for stage I, 89% (95% CI, 86%-91%) and 84% (95% CI, 80%-88%) for stage IIA, 79% (95% CI, 75%-83%) and 70% (95% CI, 62%-76%) for stage IIB, 67% (95% CI, 59%-73%) and 60% (95% CI, 51%-68%) for stage IIIA, 50% (95% CI, 33%-65%) and 50% (95% CI, 33%-65%) for stage IIIB, and 25% (95% CI, 4%-53%) (5-year only) for stage IIIC, respectively. The 160 iris melanomas were too few for subgroup analysis. CONCLUSIONS AND RELEVANCE Multicenter, worldwide, Internet-based data sharing was used to study a heterogenous patient population in ophthalmic o...

International multicenter data sharing was used to evaluate the effect of local tumor recurrence on metastatic rate. In that local tumor recurrence was associated with a significantly higher risk of systemic metastasis, effective initial treatment and long-term surveillance of treated uveal melanoma patients is necessary.

ObjectiveTo analyse ocular and systemic findings of patients presenting with systemic metastasis.Methods and analysisIt is an international, multicentre, internet-enabled, registry-based retrospective data analysis. Patients were diagnosed between 2001 and 2011. Data included: primary tumour dimensions, extrascleral extension, ciliary body involvement, American Joint Committee on Cancer (AJCC)-tumour, node, metastasis staging, characteristics of metastases.ResultsOf 3610 patients with uveal melanoma, 69 (1.9%; 95% CI 1.5 to 2.4) presented with clinical metastasis (stage IV). These melanomas originated in the iris, ciliary body and choroid in 4%, 16% and 80% of eyes, respectively. Using eighth edition AJCC, 8 (11%), 20 (29%), 24 (35%), and 17 (25%) belonged to AJCC T-categories T1–T4. Risk of synchronous metastases increased from 0.7% (T1) to 1.5% (T2), 2.6% (T3) and 7.9% (T4). Regional lymph node metastases (N1a) were detected in 9 (13%) patients of whom 6 (67%) had extrascleral extension. Stage of systemic metastases (known for 40 (59%) stage IV patients) revealed 14 (35%), 25 (63%) and 1 (2%) had small (M1a), medium-sized (M1b) and large-sized (M1c) metastases, respectively. Location of metastases in stage IV patients were liver (91%), lung (16%), bone (9%), brain (6%), subcutaneous tissue (4%) and others (5%). Multiple sites of metastases were noted in 24%. Compared with the 98.1% of patients who did not present with metastases, those with synchronous metastases had larger intraocular tumours, more frequent extrascleral extension, ciliary body involvement and thus a higher AJCC T-category.ConclusionsThough higher AJCC T-stage was associated with risk for metastases at diagnosis, even small T1 tumours were stage IV at initial presentation. The liver was the most common site of metastases; however, frequent multiorgan involvement supports initial whole-body staging.

This study confirms that children with CCBM have a more favorable survival than young adults 18 to 25 years of age, adjusting for TNM stage and gender. The association between gender and survival varies between age groups.
