Rapid histopathological testing, also known as frozen biopsy, can accurately determine whether a tumor is benign or malignant within 15-30 minutes. This information allows doctors to make informed decisions regarding the most suitable surgical direction for the patient. Dr. Nguyen Van Thai, Deputy Pathologist at Tam Anh General Hospital in Ho Chi Minh City, explained that frozen biopsy is conducted concurrently with surgery to determine the nature of tumors, body tissues, or lymph nodes. Based on the 92% accurate results, the surgeon can provide appropriate treatment guidance, ultimately improving the success rate of surgery and subsequent treatment.
Frozen biopsy is particularly useful in evaluating whether there are still malignant cells present in the margin section during melanoma surgery. This approach allows patients to undergo only one surgery to address both diagnostic biopsy and surgical treatment, optimizing efficiency in patient care. Dr. Huynh Ba Tan from the Department of Breast Surgery at Tam Anh General Hospital highlighted the importance of frozen biopsy in enabling accurate surgical decisions and preventing the need for repeat surgeries based solely on medical experience.
In cases of early-stage breast cancer, frozen sentinel lymph node biopsy is crucial when there are no apparent abnormalities in axillary lymph nodes observed through ultrasound and mammogram results. The sentinel lymph node plays a critical role in determining the risk of cancer cell spread to other lymph nodes in the armpit. By removing the sentinel lymph node and assessing for malignant cells, doctors can make informed decisions regarding further treatment steps for the patient.
Prior to advancements in frozen sentinel lymph node biopsy techniques, breast cancer patients typically underwent comprehensive removal of all axillary lymph nodes irrespective of cancer stage. This approach often led to complications such as lymphedema characterized by arm swelling, pain, and limited mobility. With advancements in frozen biopsy techniques like those utilized by Ms. Hong’s surgical team at Tam Anh General Hospital’s Pathology Unit
