Department of Breast Radiation Oncology, The University of Texas MD Anderson Cancer Center, 1515 Holcombe Blvd, Houston, TX, 77030, USA.

Article Synopsis
  • Recent advancements in breast cancer treatment have altered traditional radiotherapy practices, moving from lengthy regimens to potentially only 5 treatments in a week for selected patients.
  • Ultra-hypofractionated regimens and partial breast irradiation have shown efficacy and tolerability, offering alternatives to whole breast radiation.
  • The evolving research emphasizes patient-centered care, highlighting the importance of personalized treatment plans and shared decision-making in oncology.

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 CDP in finding the involved cavity side margins which were not diagnosed by permananet pathology of their tumor side interface.

Purpose: This study aimed to evaluate the impact of lidocaine-saline solution compared to saline alone for washing out the lumpectomy cavity, focusing on its effect on acute postoperative pain-a prevalent and significant concern among patients undergoing breast surgery.

Methods: In this comparative study, 72 patients scheduled for lumpectomy surgery were randomly assigned to either the lidocaine-saline or saline group. The lidocaine-saline group was administered a washout of the lumpectomy cavity with 2 % lidocaine at a dosage of 1.

Background: In patients undergoing breast-conserving therapy without surgical clip implantation, the accuracy of tumor bed identification and the consistency of clinical target volume (CTV) delineation under computed tomography (CT) simulation remain suboptimal. This study aimed to investigate the feasibility of implementing preoperative magnetic resonance (MR) simulation on delineations by assessing interobserver variability (IOV).

Methods: Preoperative MR and postoperative CT simulations were performed in patients who underwent breast-conserving surgery with no surgical clips implanted.

Background: Intraoperative radiation therapy (IORT) and whole breast irradiation (WBI) are both effective adjuvant radiotherapy methods for ductal carcinoma (DCIS) or early-stage breast cancer (BC) patients undergoing breast-conserving surgery (BCS). We aim to evaluate the long-term oncological efficacy and refine patient selection criteria based on our findings.

Methods: Female patients who underwent either IORT or WBI from January 2016 to December 2019, with a minimum follow-up of 12 months were collected.
