Determinants of prognosis were studied in patients with breast cancer with histologically proven tumor extension to the skin without clinical evidence of distant metastases (i.e., pT4b N0–3 M0). Data were collected retrospectively on 77 consecutive patients diagnosed in one community teaching hospital over the period from 1980 to 1995. The prognostic factor of tumor size showed a 5‐year survival rate for patients with a tumor ≤3 cm of 81% compared to 45% for patients with tumors larger than 3 cm (p = 0.002). Achievement of complete remission resulted in a 5‐year survival rate of 66%, compared to 27% when complete remission was not achieved (p = 0.005). Another important prognostic factor was the development of local‐regional recurrence: the 5‐year survival rates for patients with and without local‐regional recurrence were 39% and 87%, respectively (p < 0.001). Development of local‐regional recurrence was also significantly related to tumor size (p = 0.02). Pathologic tumor size and the achievement of complete remission and local‐regional control appear to be the most important prognostic factors for survival in patients with pT4b breast cancer without distant metastases. We conclude that the finding of a pT4b breast cancer does not always imply a dismal prognosis, especially for those patients with a tumor ≤3 cm. A favorable prognosis can be expected when treatment is effective in achieving complete remission and in preventing the development of local‐regional recurrence.
