Primary breast cancer tissue and lymph nodes were obtained from 48 patients. Estrogen receptors (ER) and progesterone receptors (PgR) were determined by a dextran-coated charcoal assay. ER were present in 72.9 % of the primary tumors and in 62.4 % of the malignant lymph nodes, whereas PgR were present in 73.0 % and 50.0 % of the cases, respectively. The primary tumor and the corresponding malignant lymph nodes showed an identical ER and PgR status, i.e., both tumor sites were receptor positive or both receptor negative in 89.6 % and 77.1 %, respectively. However, 10.4 % of the patients had ER-positive tumors but ER-negative lymph nodes and 22.9 % had PgR-positive primaries with PgR-negative lymph nodes. No receptor-positive lymph nodes showed a combination with receptor-negative primary tumor. This preliminary data shows that receptor-positive malignant lymph nodes mostly display the same receptor status as the corresponding primary tumor, whereas receptor-negative lymph nodes may have a receptor-positive primary tumor.

PURPOSE: To define clinical and pathologic predictors of local-regional recurrence (LRR) for patients treated with neoadjuvant chemotherapy and mastectomy without radiation. PATIENTS AND METHODS: We analyzed the outcome of the 150 breast cancer cases treated on prospective institutional trials with neoadjuvant chemotherapy and mastectomy without postmastectomy radiation. Clinical stage at diagnosis was I in 1%, II in 43%, IIIA in 23%, IIIB in 25%, and IV in 7%. No patient had inflammatory breast cancer. RESULTS: The median follow-up period of surviving patients was 4.1 years. The 5- and 10-year actuarial rates of LRR were both 27%. Pretreatment factors that positively correlated with LRR were increasing T stage (P < .0001) and increasing combined clinical stage (P < .0001). Pathologic and treatment factors that positively correlated with LRR were size of the residual primary tumor (P = .0048), increasing number of involved lymph nodes (P < .0001), and no use of tamoxifen (P = .0013). The LRR rate for the 18 patients with a pathologic complete response of both the primary tumor and lymph nodes (pCR) was 19% (95% confidence interval, 6% to 48%). In a forward stepwise Cox logistic regression analysis, clinical stage IIIB or greater (hazard ratio of 4.5, P < .001), pathologic involvement of four or more lymph nodes (hazard ratio of 2.7, P = .008), and no use of tamoxifen (hazard ratio of 3.9, P = .027) independently predicted for LRR. CONCLUSION: Advanced disease at presentation and positive lymph nodes after chemotherapy predict for clinically significant rates of LRR. Achievement of pCR does not preclude the need for postmastectomy radiation if warranted by the pretreatment stage of the disease.

Background Neoadjuvant chemotherapy has been increasingly utilized in the treatment of breast cancer patients. However, there are no established surrogate markers predicting the response to subsequent adjuvant therapy and clinical outcome of patients. In particular, whether primary or lymph nodes metastasis should be evaluated for these analyses has remained unknown. Therefore, in this study, we first evaluated the differences in biomarkers between primary and metastatic cancer tissues in the patients undergoing neoadjuvant chemotherapy. We then correlated the findings with the clinical outcomes of these patients. Methods We examined 49 patients receiving neoadjuvant chemotherapy and subsequent surgery with lymph node metastasis. Estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor 2 (HER2) and Ki-67 were all immunohistochemically evaluated in core needle biopsy samples from primary and metastatic tumors following chemotherapy. Results No statistically significant differences in these markers were detected between the primary tumor and metastatic lymph nodes following therapy, but the Ki-67 labeling index was significantly higher in metastatic lymph nodes than in primary tumor (p = 0.017). The patients associated with luminal A type carcinoma in their lymph nodes following chemotherapy demonstrated significantly better clinical outcomes (disease-free survival: p = 0.0045, overall survival: p = 0.0006) than those who were not. Conclusion These data indicate that subtype classification following chemotherapy, in the metastatic lymph nodes rather than primary tumor could predict long-term outcomes of patients undergoing neoadjuvant chemotherapy.
