Abstract

Objective: To analyze the rate of axillary recurrences and survival in patients operated on for breast cancer who had not undergone an axillary lymph node dissection (ALND) because of a negative sentinel node biopsy. Methods: The study includes 97 patients operated on for breast cancer and selective node biopsy from June 2000 to December 2001 who had a negative sentinel node biopsy and did not undergo ALND. Mean age was 58.2 years (55.9–60.5). Follow-up was done up to 5 years. After surgery all patients underwent clinical examination. Complementary treatment depended on the hospital protocol. Rate of axillary recurrences, presence of distant metastases and survival (Kaplan-Meier method) were studied. Results: After a median follow-up of 4.1 years (2.18–5.25), only 2/95 patients (2.1%) developed distant metastases. Four patients died but only the death of the patient who presented multiple metastases was related to the primary breast cancer (1%). The 5-year overall survival rate was 96%. Conclusions: (1) Only 1/95 patients studied developed nodal extra-axillary recurrence together with distant metastases. (2) The results obtained support the selective sentinel node biopsy as an accurate technique in the axillary stratification of patients with breast cancer, offering in the cases of negative sentinel node biopsy a safe axillary control after a 5-year follow-up.

A randomized comparison of sentinel-node biopsy with routine axillary dissection in breast cancer.

Umberto Veronesi, Giovanni Paganelli, Giuseppe Viale … (2003)

Although numerous studies have shown that the status of the sentinel node is an accurate predictor of the status of the axillary nodes in breast cancer, the efficacy and safety of sentinel-node biopsy require validation. From March 1998 to December 1999, we randomly assigned 516 patients with primary breast cancer in whom the tumor was less than or equal to 2 cm in diameter either to sentinel-node biopsy and total axillary dissection (the axillary-dissection group) or to sentinel-node biopsy followed by axillary dissection only if the sentinel node contained metastases (the sentinel-node group). The number of sentinel nodes found was the same in the two groups. A sentinel node was positive in 83 of the 257 patients in the axillary-dissection group (32.3 percent), and in 92 of the 259 patients in the sentinel-node group (35.5 percent). In the axillary-dissection group, the overall accuracy of the sentinel-node status was 96.9 percent, the sensitivity 91.2 percent, and the specificity 100 percent. There was less pain and better arm mobility in the patients who underwent sentinel-node biopsy only than in those who also underwent axillary dissection. There were 15 events associated with breast cancer in the axillary-dissection group and 10 such events in the sentinel-node group. Among the 167 patients who did not undergo axillary dissection, there were no cases of overt axillary metastasis during follow-up. Sentinel-node biopsy is a safe and accurate method of screening the axillary nodes for metastasis in women with a small breast cancer. Copyright 2003 Massachusetts Medical Society

Surgical resection and radiolocalization of the sentinel lymph node in breast cancer using a gamma probe.

D Krag, Jessica D Weaver, J Fairbank … (1993)

We have recently reported on a technique of gamma probe localization of radiolabelled lymph nodes to identify the sentinel node in malignant melanoma. In order to determine whether this technique is applicable to assist in staging breast cancer, a pilot study was begun to address two questions: (i) can the sentinel lymph node draining a breast cancer be identified for selective resection; and (ii) is the sentinel lymph node predictive of the status of the entire axillary lymph nodes? One to four hours prior to axillary lymph node dissection, 22 consecutive patients had approximately 0.4 mCi of technetium sulfur colloid in 0.5 ml saline injected around the perimeter of the breast lesion. A hand-held gamma counter was used at surgery to locate the lymph node(s) receiving drainage from the breast. A sentinel lymph node was identified in 18 of 22 patients. Of these 18 patients, the sentinel lymph node was positive in seven of seven patients, with pathologically verified metastatic breast cancer to at least one lymph node. In three out of seven patients, the sentinel lymph node was the only lymph node with metastatic cancer. In this pilot study of breast cancer patients, we conclude that: (i) radiolocalization and selective resection of sentinel lymph nodes is possible; and (ii) the sentinel lymph node appears to predict correctly the status of the remaining axilla. These data justify a larger clinical trial to verify the value of this technique.

Ten-year results of a randomized clinical trial comparing radical mastectomy and total mastectomy with or without radiation.

B. Fisher, C. Redmond, E Fisher … (1985)

In 1971 we began a randomized trial to compare alternative local and regional treatments of breast cancer, all of which employ breast removal. Life-table estimates were obtained for 1665 women enrolled in the study for a mean of 126 months. There were no significant differences among three groups of patients with clinically negative axillary nodes, with respect to disease-free survival, distant-disease--free survival, or overall survival (about 57 per cent) at 10 years. The patients were treated by radical mastectomy, total ("simple") mastectomy without axillary dissection but with regional irradiation, or total mastectomy without irradiation plus axillary dissection only if nodes were subsequently positive. Similarly, no differences were observed between patients with clinically positive nodes treated by radical mastectomy or by total mastectomy without axillary dissection but with regional irradiation. Survival at 10 years was about 38 per cent in both groups. Our findings indicate that the location of a breast tumor does not influence the prognosis and that irradiation of internal mammary nodes in patients with inner-quadrant lesions does not improve survival. The data also demonstrate that the results obtained at five years accurately predict the outcome at 10 years. We conclude that the variations of local and regional treatment used in this study are not important in determining survival of patients with breast cancer.
