Breast CancerPhase 2NCT00881361
Surgery to Remove the Sentinel Lymph Node and Axillary Lymph Nodes After Chemotherapy in Treating Women With Stage II, Stage IIIA, or Stage IIIB Breast Cancer
A Phase 2 study testing systemic chemotherapy, axillary lymph node dissection and neoadjuvant therapy in people with Breast Cancer, run by Alliance for Clinical Trials in Oncology at 324 sites in United States.
Trial summary
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Read more about this study

- Adult, Older adult
Eligibility Criteria:
- ≥ 18 years old
- ECOG/Zubrod Performance Status 0-1
- Female. Note: Men are excluded from this study because the number of men with breast cancer is insufficient to provide a statistical basis for assessment of effects in this subpopulation of people with breast cancer.
- Histologic diagnosis of invasive breast cancer, clinical stage T0-4 N1-2 M0 (excluding inflammatory breast cancer).
- FNA biopsy or core needle biopsy of an axillary node documenting nodal disease at time of diagnosis and prior to preoperative chemotherapy.
- Preoperative chemotherapy must be completed or planned for patient. NOTE: Patients enrolling on studies involving preoperative chemotherapy (through cooperative groups or institutional studies) may be eligible for this study, provided sentinel node surgery prior to preoperative chemotherapy was not required in the other studies.
- No prior ipsilateral axillary surgery, such as excisional biopsy of lymph node(s) or treatment of hidradenitis.
- No prior SLN surgery/excisional lymph node biopsy for pathological confirmation of axillary status.

About this study
Official title: A Phase II Study Evaluating the Role of Sentinel Lymph Node Surgery and Axillary Lymph Node Dissection Following Preoperative Chemotherapy in Women With Node Positive Breast Cancer (T1-4, N1-2, M0) at Initial Diagnosis
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
PURPOSE: This phase II trial is studying surgery to remove the sentinel lymph node and axillary lymph nodes after chemotherapy in treating women with stage II, stage IIIA, or stage IIIB breast cancer.
Read the detailed description
This is a multicenter study. Patients who plan to receive or have received neoadjuvant chemotherapy are eligible. Patients undergo examination for breast and axilla lymph adenopathy and then undergo ultrasound of the axillary nodes prior to registration to confirm eligibility and after completion of neoadjuvant chemotherapy. Within 12 weeks of completing neoadjuvant chemotherapy, patients undergo a mastectomy or lumpectomy (per surgeon discretion) including both sentinel lymph node surgery and axillary lymph node dissection. The primary and secondary objectives of the study are described below.
Primary Objective:
- To determine the false negative rate for sentinel lymph node (SLN) surgery. Among the patients who have at least one sentinel lymph node identified and removed, false negative rate is defined as the number of patients declared to have no evidence of cancer in the SLN and are found to have at least one positive lymph node in the ALND divided by the total number of patients with at least one positive axillary lymph node by ALND.
Secondary Objectives:
- To determine how the axillary ultrasound status of the patient upon completion of preoperative chemotherapy (evidence of residual lymphadenopathy on the ultrasound examination versus no evidence of lymphadenopathy in the ultrasound examination) affects the false negative rate of SLN and how sonographic findings correlate with residual disease on final pathology.
- To determine the node status of patients after preoperative chemotherapy. Patients will be classified as node positive if they were determined to have at least one positive lymph node by SLN or ALND. Patients will be classified as node negative if all nodes examined by SLN and ALND were negative.
- To determine whether the false-negative rate for SLN surgery after preoperative chemotherapy is related to the extent of residual cancer burden (RCB) overall, or separately in the breast or regional nodal basin.
- To evaluate pathological complete response (pCR) rates (defined as no invasive disease in breast or lymph nodes) and disease-free survival (DFS) rates in node-positive patients receiving preoperative chemotherapy.
After completion of surgery, patients will visit the office for follow-up exams at 1-2 weeks then patients are followed every 6 months for 2 years, yearly for 2 years, then every other year for 6 years. The study closed to accrual and treatment on 5/29/12.

What is being measured
The primary outcome is the main question the study is designed to answer.
False Negative Rate (FNR) for Sentinel Lymph Node (SLN) Surgery After Chemotherapy When at Least 2 SLNs Were Excised in Women Initially Presenting With Biopsy-proven cN1 Breast Cancer [cN1 Cohort]
False negative rate (FNR) (percentage) for sentinel lymph node (SLN) surgery after chemotherapy when at least 2 SLNs were excised in women initially presenting with biopsy-proven cN1 breast cancer, defined as the number of patients with no positive lymph nodes by SLN and with at least one positive lymph node by axillary lymph node dissection (ALND) divided by the total number of patients initially presenting with biopsy-proven cN1 breast cancer with at least one positive lymph node by SLN or ALND multiplied by 100. A 2-sided Bayesian credible interval (BCI) for the true FNR was constructed.
Measured: At time of surgery
Secondary outcomes (5)
False Negative Rate (FNR) for Sentinel Lymph Node (SLN) Surgery After Chemotherapy When at Least 2 SLNs Were Excised in Women Initially Presenting With Biopsy-proven cN2 Breast Cancer [cN2 Cohort]
False negative rate (FNR) (percentage) for sentinel lymph node (SLN) surgery after chemotherapy when at least 2 SLNs were excised in women initially presenting with biopsy-proven cN2 breast cancer, defined as the number of patients with no positive lymph nodes by SLN and with at least one positive lymph node by axillary lymph node dissection (ALND) divided by the total number of patients initially presenting with biopsy-proven cN1 breast cancer with at least one positive lymph node by SLN or ALND multiplied by 100. An interval estimate of the SLN false negative rate will be constructed using the Duffy-Santner approach.
Measured: At time of surgery
False-negative Rate (FNR) Under the Selection Process by Axillary Ultrasound (AUS) Status After Completion of Neoadjuvant Chemotherapy (NAC)
False negative rate (FNR) (percentage) for sentinel lymph node (SLN) surgery after chemotherapy in women with normal AUS and at least 2 SLNs were excised, defined as the number of patients with no positive lymph nodes by SLN and with at least one positive lymph node by axillary lymph node dissection (ALND) divided by the total number of patients with at least one positive lymph node by SLN or ALND multiplied by 100.
Measured: At the time of surgery
Node Status After Preoperative Chemotherapy, as Measured by the Total Number of Positive Nodes (SLN+ALND)
Node status of patients after preoperative chemotherapy, as measured by the total number of positive nodes (SLN+ALND). Patients will be classified as node positive if they were determined to have at least one positive lymph node by SLN or ALND.
Measured: At time of surgery
Pathologic Complete Nodal Response (pCR) Rate
Pathologic complete nodal response (pCR) rate (percentage) wherein a nodal pCR is pathologically node-negative (pN0) on the basis of SLN surgery and ALND. A 95% binomial confidence interval was constructed for the pCR rate.
Measured: At the time of surgery
Residual Cancer Burden Class
Residual cancer burden (RCB) is estimated from routine pathologic sections of the primary breast tumor site and the regional lymph nodes after the completion of neoadjuvant therapy. The calculated RCB index value can also be categorized as one of four RCB classes. The number of patients classified in the four RCB classes along with the number of patients missing this data by cohort are reported below. RCB of 0 represents a path complete response while increasing levels (I, then II, then III) indicate an increase in the 'amount' of residual disease remaining.
Measured: At time of surgery

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
PURPOSE: This phase II trial is studying surgery to remove the sentinel lymph node and axillary lymph nodes after chemotherapy in treating women with stage II, stage IIIA, or stage IIIB breast cancer.
Detailed description
This is a multicenter study. Patients who plan to receive or have received neoadjuvant chemotherapy are eligible. Patients undergo examination for breast and axilla lymph adenopathy and then undergo ultrasound of the axillary nodes prior to registration to confirm eligibility and after completion of neoadjuvant chemotherapy. Within 12 weeks of completing neoadjuvant chemotherapy, patients undergo a mastectomy or lumpectomy (per surgeon discretion) including both sentinel lymph node surgery and axillary lymph node dissection. The primary and secondary objectives of the study are described below.
Primary Objective:
- To determine the false negative rate for sentinel lymph node (SLN) surgery. Among the patients who have at least one sentinel lymph node identified and removed, false negative rate is defined as the number of patients declared to have no evidence of cancer in the SLN and are found to have at least one positive lymph node in the ALND divided by the total number of patients with at least one positive axillary lymph node by ALND.
Secondary Objectives:
- To determine how the axillary ultrasound status of the patient upon completion of preoperative chemotherapy (evidence of residual lymphadenopathy on the ultrasound examination versus no evidence of lymphadenopathy in the ultrasound examination) affects the false negative rate of SLN and how sonographic findings correlate with residual disease on final pathology.
- To determine the node status of patients after preoperative chemotherapy. Patients will be classified as node positive if they were determined to have at least one positive lymph node by SLN or ALND. Patients will be classified as node negative if all nodes examined by SLN and ALND were negative.
- To determine whether the false-negative rate for SLN surgery after preoperative chemotherapy is related to the extent of residual cancer burden (RCB) overall, or separately in the breast or regional nodal basin.
- To evaluate pathological complete response (pCR) rates (defined as no invasive disease in breast or lymph nodes) and disease-free survival (DFS) rates in node-positive patients receiving preoperative chemotherapy.
After completion of surgery, patients will visit the office for follow-up exams at 1-2 weeks then patients are followed every 6 months for 2 years, yearly for 2 years, then every other year for 6 years. The study closed to accrual and treatment on 5/29/12.
