['To determine whether T category of the American Joint Committee on Cancer (AJCC) TNM staging system for eyelid carcinoma, 7th edition, correlates with lymph node metastasis, distant metastasis, and survival in patients with sebaceous carcinoma of the eyelid.', 'Retrospective, cohort study.', 'Fifty consecutive patients treated by 1 author (BE) for eyelid sebaceous carcinoma between May 1999 and August 2010.', 'Each tumor was staged according to the AJCC 7th edition TNM criteria. The Kaplan-Meier method was used to determine associations between disease-specific survival and (1) T category at presentation, (2) lymph node metastasis, and (3) distant metastasis.', 'T category at presentation, nodal metastasis, survival.', 'The study included 37 women and 13 men (median age, 68.5 years; range, 44-86 years). Forty-four patients were white, 5 were Hispanic, and 1 was Asian. TNM designations were TXN0M0, 7 patients; T1N0M0, 4 patients; T2aN0M0, 12 patients; T2bN0M0, 11 patients; T2bN1M0, 2 patients; T2bN1M1, 1 patient; T3aN0M0, 2 patients; T3aN1M0, 5 patients; T3bN0M0, 1 patient; T3bN1M0, 1 patient; T3bN0M1, 2 patients; T4N0M0, 1 patient; and T4N0M1, 1 patient. T category at presentation was significantly associated with lymph node metastasis (P = 0.0079). No tumors with T category better than T2b or smaller than 9 mm in greatest dimension were associated with nodal metastasis. Five patients (10%) died of disease during follow-up. Their TNM designations were T2bN1M1, 1 patient; T3bN0M1, 2 patients; T4N0M0, 1 patient; and T4N0M1, 1 patient. No tumors smaller than 12 mm in greatest dimension were associated with distant metastasis or death. T category was significantly associated with disease-specific survival (P = 0.0009). Disease-specific survival was poorer among patients with T category of T3a or worse (P = 0.035).'] Does american Joint Committee on Cancer T category for eyelid sebaceous carcinoma correlate with nodal metastasis and survival?
