摘要
Between 1977 and 1986, 886 pts with Stage I and II breast cancer underwent excisional biopsy, axillary dissection and radiation. Median follow-up was 5 years (range 2 months-13 years). The patients were divided into four groups according to the primary tumor location: 1) outer (495 patients), 2) inner (202 patients), 3) central (119 patients), and 4) subareolar (70 patients). Subareolar tumors were defined as those immediately beneath the nipple-areolar complex or within 2 cm of the areolar margin. The comparability of the groups was assed in terms of clinical T stage, patient age, histology, final pathologic margin status, estrogen and progesterone receptor status, pathologic nodal status, and use of adjuvant chemotherapy. There were no significant differences among the four groups in the distribution of these factors except for the pathologic nodal status (outer 38% positive nodes, inner 24%, central 23%, subareolar 31%) p = .0004. There were no significant differences in 5 year actuarial overall survival (91% vs 86% vs 92% vs 91%, p = .34), relapse-free (75% vs 74% vs 80% vs 79%, p = .77), or NED survival (82% vs 78% vs 87% vs 84%, p = .29) for the four groups. A separate analysis for pathologic node negative and node positive patients revealed similar findings. For node-negative patients, the 5 year actuarial overall survival was 93% vs 88% vs 94% vs 91% (p = .20), the relapse-free survival was 78% vs 76% vs 82% vs 79% (p = .49), and the NED survival was 86% vs 81% vs 88% vs 86% (p = .46). For node-positive patients, the 5 year actuarial overall survival was 87% vs 82% vs 84% vs 90% (p = .59), relapse-free survival was 69% vs 66% vs 77% vs 80% (p = .78), and NED survival was 75% vs 68% vs 85% vs 80% (p = .66). Patterns of first failure were also not significantly different among the four groups: local only first failure (7% vs 4% vs 5% vs 8%, p = .49), any local first failure, i.e., +/-simultaneous distant metastases (8% vs 5% vs 5% vs 9%, p = .61), regional only (2% vs 1% vs 1% vs 0%, p = .65), any regional (4% vs 3% vs 3% vs 3%), or distant metastases (11% vs 17% vs 9% vs 10%, p = .16). A separate analysis of node negative and node positive patients revealed similar findings. The present analysis demonstrates no significant correlation between primary tumor location and patterns of first failure, overall survival, relapse-free, or no evidence of disease (NED) survival in 886 pts with Stage I and II breast cancer treated with conservative surgery and radiation. Subareolar tumor location was not associated with an increased risk of breast recurrence in appropriately selected patients.
