Objectives

Narrative objectives1

We are going to do a prospective multicenter clinical trial confirming the feasibility of imprinted cell diagnosis using the CTS method including intraoperative assessment of resection stumps for breast conserving surgery (BCS) with breast cancer. The aim of this trial is investigated whether CTS method demonstrate non-inferiority to histological diagnosis of frozen sections in clinical practice. We will try to confirm the concordance rate (correct diagnosis rate) and specificity (false positive rate) in between CTS method and permanent pathological diagnosis.

Basic objectives2

Others

Basic objectives -Others

t would be useful to consider applying automatic deep learning and AI algorithms as a diagnostic tool in CTS imaging diagnosis. At the Department of Information Science, Osaka University, AI would automatically and rapidly evaluate cancer margins.

Assessment

Primary outcomes

1) The feasibility of the CTS method will be confirmed by confirming the achievement rate for the diagnostic results of the CTS method by the multicenter clinical trial.
2)CTS method demonstrate non-inferiority to histological diagnosis of frozen sections in clinical practice. We will try to confirm the concordance rate (correct diagnosis rate) and specificity (false positive rate) in between CTS method and permanent pathological diagnosis.

Key secondary outcomes

1) We will try to confirm the concordance rate (correct diagnosis rate) and specificity (false positive rate) in between intraopetative pathological diagnosis of frozen section. and permanent pathological diagnosis.
2) We will try to confirm that additional intraoperative stump resection and the operation by positive postoperative histopathological diagnosis (by permanent specimen section) Confirm the presence or absence of additional treatment (reoperation / Boost radiation therapy) in the multicenter clinical trial.
