Purpose Lymph node (LN) –negative breast cancer tumors ≥ 5 cm occur infrequently, and their optimal management is not well defined. In this study, we assess patterns of locoregional failure (LRF) in LN-negative patients who underwent mastectomy, either with or without adjuvant chemotherapy or hormonal therapy and without postmastectomy radiation therapy (PMRT). Patients and Methods Of 8,878 breast cancer patients enrolled onto National Surgical Adjuvant Breast and Bowel Project B-13, B-14, B-19, B-20, and B-23 node-negative trials, 313 had tumors that were 5 cm or larger (median, 5.5 cm; range, 5.0 to 15.5 cm) at pathology and were treated by mastectomy. Median follow-up time was 15.1 years. Therapy included adjuvant chemotherapy in 34.2% of patients; tamoxifen in 21.1%; chemotherapy plus tamoxifen in 19.2%; and no systemic therapy in 25.5%. Results Twenty-eight patients experienced LRF. The overall 10-year cumulative incidences of isolated LRF, LRF with and without distant failure (DF), and DF alone as first event were 7.1%, 10.0%, and 23.6%, respectively. Cumulative incidences for isolated LRF as first event for patients with tumors of 5 cm or more than 5 cm were 7.0% and 7.2%, respectively (P = .9). For patients who underwent no systemic treatment, chemotherapy alone, tamoxifen alone, or chemotherapy plus tamoxifen, the incidences were 12.6%, 5.6%, 4.6%, and 5.3%, respectively (P = .2). The majority of failures occurred on the chest wall (24 of 28 patients). Multivariate analysis did not identify significant prognostic factors for LRF. Conclusion In patients with LN-negative tumors ≥ 5 cm who are treated by mastectomy with or without adjuvant systemic therapy and no PMRT, LRF as first event remains low. PMRT should not be routinely used for these patients.

In axillary node-negative primary breast cancer, 70% of the patients will be cured by locoregional treatment alone. Therefore, adjuvant systemic therapy is only needed for those 30% of node-negative patients who will relapse after primary therapy and eventually die of metastases. Traditional histomorphological and clinical factors do not provide sufficient information to allow accurate risk group assessment in order to identify node-negative patients who might benefit from adjuvant systemic therapy. In the last decade various groups have reported a strong and statistically independent prognostic impact of the serine protease uPA (urokinase-type plasminogen activator) and its inhibitor PAI-1 (plasminogen activator inhibitor type 1) in node-negative breast cancer patients. Based on these data, a prospective multicenter therapy trial in node-negative breast cancer patients was started in Germany in June 1993, supported by the German Research Association (DFG). Axillary node-negative breast cancer patients with high levels of either or both proteolytic factors in the tumor tissue were randomized to adjuvant CMF chemotherapy versus observation only. Recruitment was continued until the end of 1998, by which time 684 patients had been enrolled. Since then, patients have been followed up in order to assess the value of uPA and PAI-1 determination as an adequate selection criterion for adjuvant chemotherapy in node-negative breast cancer patients. This paper reports on the rationale and design of this prospective multicenter clinical trial, which may have an impact on future policies in prognosis-oriented treatment strategies.

This study correlates the disease-free survival (DFS), distant disease-free survival (DDFS), and survival (S) of 1,157 histologically node negative breast cancer patients with the estrogen and/or progesterone receptor (ER, PR) and with the nuclear or histologic grade (NG, HG) of their tumors. All were treated by operation without systemic adjuvant therapy. The DFS, DDFS, and S were significantly greater (P = .005, .004, less than .001) in patients with ER positive than ER negative tumors but the magnitude of the differences after 5 years of follow-up was slight (8% in both DFS and DDFS and 10% in S). Differences of that magnitude are insufficient to discriminate clearly between patients who should or should not receive systemic therapy. As with ER, there were outcome differences in favor of PR positive tumors but only in S was the difference significant (8% at 5 years; P = .002). When combined with ER, PR made no independent contribution in the outcome prediction. Regression analysis indicated that NG was the most important single marker of outcome. The prognosis of women with unknown ER or PR was equivalent to or better than that in those with ER or PR positive tumors. This finding seems to be related to tumor size in that a higher proportion of tumors with unknown receptors were less than 1.0 cm, thus having insufficient tissue for analysis. Our findings disclose that in node negative breast cancer patients, NG is a better marker of prognosis than is tumor ER, and that PR is of little or no value. Tumor NG may also be useful for selecting the type of systemic therapy to be used in these patients.
