Clinical validation on role of cancer diagnostic probe in detecting the involved cavity margins missed in permanent pathology of tumor side in breast cancer surgery

Sep 21, 2026

Cancer diagnostic probe (CDP) is evaluated as a real-time tool for breast cavity margin assessment, targeting improvements beyond conventional intra-operative margin shaving approaches. The system increased involved margin detection to 30% compared with frozen section. This study highlights CDP’s independent ability to identify involved cavity side margins not reported by permanent pathology at the tumor side interface. Among 147 CDP-detected margins, 23 lesions were missed as involved in permanent pathology, and histology served as the gold standard.

Introduction

Abbasvandi et al. Diagnostic Pathology (2024) 19:148 [https://doi.org/10.1186/s13000-024-01574-2](https://doi.org/10.1186/s13000-024-01574-2) Diagnostic Pathology RESEARCH Open Access Clinical validation on role of cancer diagnostic probe in detecting the involved cavity margins missed in permanent pathology of tumor side in breast cancer surgery Fereshteh Abbasvandi1,2,3†, Zohreh Sadat Miripour1†, Mahdis Bayat 1,3, Seyed Mohamad Sadegh Mousavi-Kiasary1, Samira Shayanfar3, Fatemeh Shojaeian1,3, Faeze Aghaei1, Fahimeh Jahanbakhshi1, Niloofar Abbasvandi1,2, Maryam Omranihashemi3, Atieh Akbari3, Morteza Yousefi3, Mohammad Hadizadeh 1, Naiemeh Shahrabi Farahani3, Parisa Hosseinpoor 1,2,4, Mohammad Parniani2, Zeinab Nourinjad2, Mohammad Abdolahad1,5* and Mohammad Esmaeil Akbari3 Abstract Cancer diagnostic probe (CDP) as a newly entered tool in real-time breast cavity margin evaluation showed great improvement in smart margin shaving intra-operatively. This system increased the rate of involved margin detection to 30% with respect to frozen section. In this study for the first time we showed the independent role of CDPin finding the involved cavity side margins which were not diagnosed by permananet pathology of their tumor side interface. Among 147 detected margins by CDP, 23 lesions with invasive component and ductal carcinoma in-situ/ ductal cancerization weren’t reported as involved margins in permanent pathology of tumor side. Our gold standard was the histology of cavity margin specimen had been scored as involved lesion by CDP. It seems that even when the permanent pathology of surgical margins is used for final declaration, role of CDP is irreplaceable. This distinguished achievement has been obtained intra-operatively in real-time by CDP while involved report in permanent pathology of tumor margins induce re-surgery for the patient. †Fereshteh Abbasvandi and Zohreh Sadat Miripour contributed equally to this work. *Correspondence: Mohammad Abdolahad[m.abdolahad@ut.ac.ir](m.abdolahad@ut.ac.ir); [abdolahad@tums.ac.ir](abdolahad@tums.ac.ir) 1 Nano Bioelectronics Devices Lab, Cancer Electronics Research Group, School of Electrical and Computer Engineering, Faculty of Engineering, University of Tehran, 4563-11155, Tehran, Iran 2 ATMP Department, Breast Cancer Research Center, Motamed Cancer Institute, ACECR, 1517964311, Tehran, Iran 3 Cancer Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran 4 SEPAS Pathology Laboratory, Tehran, Iran 5 Cancer Institute, Imam-Khomeini Hospital, Tehran University of Medical Sciences, Tehran, Iran © The Author(s) 2024.

FAQs

What does the cancer diagnostic probe (CDP) aim to improve in breast surgery?

CDP targets real-time evaluation of involved breast cavity margins, improving detection during intra-operative margin shaving compared with conventional approaches such as frozen section.

How did CDP performance compare with frozen section for detecting involved margins?

CDP increased the rate of involved margin detection to 30% relative to frozen section.

Why is CDP considered independent from permanent pathology in this study?

The study reports that CDP identified involved cavity side margins that were not diagnosed by permanent pathology of the tumor side interface, with 23 lesions missed as involved in permanent pathology.
