Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate if sentinel lymph node biopsy is a reliable staging tool for breast cancer patients planned for neoadjuvant chemotherapy (=before breast surgery) and if, in that case, it is safe to omit axillary lymph node dissection if the sentinel lymph node is free of metastasis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sentinel lymph node biopsy (SLNB) was introduced in the late 1990´s and has become standard procedure for staging of the axilla in early stage breast cancer associated with significantly less arm morbidity than axillary lymph node dissection (ALND).

Neoadjuvant chemotherapy (NAC) given before breast surgery is indicated for locally advanced breast cancer but is increasingly used for early stage breast cancer with the purpose of downstaging the tumor and thereby possibly enabling breast conserving surgery. Traditionally, the standard axillary staging tool has been ALND although up to 50 per cent of the patients at diagnosis do not have any metastases in their axillary lymph nodes. In addition, NAC can eradicate metastases in the axillary lymph nodes in up to 40 per cent of the patients.

SLNB has therefore been evaluated in the neoadjuvant setting both before and after NAC but is still controversial and the timing debated.

This is a Swedish prospective multi-institutional study without any comparison goup. The comparison is between the findings in the SLNB and the following ALND performed after NAC in all patients.

If the patient is clinically node-negative at diagnosis a SLNB is performed before (without frozen section) and after NAC (substudy I). The reasons for repeating SLNB both before and after NAC are 1) to find out what happens during NAC 2) if it is possible to identify a repeat SLNB and 3) if it is reliable.

If the patient is node-positive at diagnosis (cytologically verified lymph node metastasis) SLNB is performed after NAC together with the breast operation and ALND (substudy II). When SLNB is performed after NAC, the sentinel lymph nodes are also analysed with frozen section in order to validate the method after chemotherapy. Both blue dye and radiolabelled isotope for localisation of the sentinel lymph node is recommended but lymphoscintigraphy is optional.

All consecutive clinically node-negative (or with unclear nodal status after ultrasound and cytology) patients planned for NAC will have oral and written information about the study by the responsible surgeon. After accepting to participate, the patient is asked to sign a written consent. Patients with a cytologically verified lymph node metastasis/es at diagnosis will be informed and asked to participate in substudy II after completion of NAC.

According to the statistical analysis, and with an expected loss of 10 per cent, a sample size of 220 patients is needed in substudy I to show that the false negative rate is less than 10 per cent. If we include 200 patients and 50 per cent are lymph node positive at diagnosis then the estimation of false negative rate will be based on 100 individuals. If we estimate the true false negative rate to be 8 per cent, then the precision with 80 per cent power will be +/- 7 per cent units (2-sided test with 95 per cent confidence interval).

The Central Contact (PI) is responsible for data collection, management and analysis. Each protocol will be sent together with a written consent and copies of all relevant histopathological reports to the PI, who will control for missing or incongruent data and if so, ask the responsible investigator on that institution/hospital to complement the missing data from the patients journal (copies of medical records or histopathological reports).
