Background And Purpose: To evaluate intraoperative brachytherapy in the management of soft tissue sarcomas involving neurovascular structures, its impact on local control and complications.
Patients And Methods: Between 01/1989 and 12/2002, 98 patients received an intraoperative implant in conjunction with conservative surgery. Brachytherapy was part of the initial treatment (79 cases) or performed in recurrent disease (19 cases). We studied primary sarcomas involving neurovascular structures treated with conservative surgery and intraoperative brachytherapy (n = 6) or intraoperative brachytherapy and external irradiation (n = 73). Conservative surgery was performed as first treatment (51 cases), after chemotherapy (21 cases) and after primary external radiation (seven cases). Brachytherapy was performed according to Paris system rules. Patients were loaded with Iridium 192 (64 cases) or connected to a Microselectron PDR (15 cases). Mean dose given by brachytherapy was 20 Gy. Mean dose given of external radiotherapy was 46 Gy.
Results: With a median follow-up of 58 months, 5-year actuarial survival was 69% and local free disease at 5 years was 90%. Acute side-effects occurred in 22/79 requiring surgical repair in 10 patients. Late side-effects occurred in 35/79. No patient required amputation for complications. Prognostic factors were studied for the occurrence of acute and late side-effects and local control.
Conclusions: Intraoperative brachytherapy is efficient with excellent local control rates in soft tissue sarcomas presenting with neurovascular involvement and offers an acceptable conservative option.

Background: Locally recurrent and marginally resectable rectal and anorectal carcinomas present significant therapeutic challenges due to high recurrence rates and limited treatment options. Intraoperative low-dose rate brachytherapy (LDRBT) has emerged as a potential adjunct to improve local control in these cases. This study aims to evaluate the clinical outcomes associated with intraoperative LDRBT for these difficult cases.

Purpose: Radiation therapy is a core component of the standard of care (SOC) for glioblastoma (GBM), yet outcomes remain poor. Rapid early progression (REP) between maximal safe resection and start of external beam radiation therapy (EBRT) is associated with reduced survival. The GESTALT trial (NCT05342883) investigates whether initiating low-dose-rate brachytherapy (LDRBT) at time of resection can mitigate rates of REP prior to EBRT.

Purpose: To report on primary outcomes and dosimetric results of a prospective clinical trial and protocol for use of iterative intraoperative magnetic resonance imaging (iMRI) in gynecologic brachytherapy.
Methods: Patients with locally advanced cervical or vaginal cancer (FIGO stages IB2 - IVA, and stage II-IVA, respectively) undergoing pulsed dose rate (PDR) brachytherapy were enrolled in a prospective clinical trial (NCT03634267) using iterative 3T iMRI during brachytherapy implant placement. Applicator and optional interstitial needles were placed under iMRI guidance in a 3T clinical MRI scanner.

This paper enhances prostate brachytherapy robot accuracy by developing a needle deflection prediction model and a controlled puncturing strategy, addressing current challenges and trends. The study addresses the challenges in needle deflection prediction by proposing a correction force-based prediction model. The puncture control strategy comprises two phases: preoperative needle trajectory planning and intraoperative approach adjustment, both relying on corrective force.

Purpose: Magnetic resonance image-guided brachytherapy (MRgBT) is the gold-standard treatment for cervical cancer. This study examined workflow times in an integrated MRgBT suite and conventional operating room (OR), and factors contributing to intraoperative efficiency.
Methods And Materials: Consecutive patients with FIGO stage IB-IVA cervical cancer who underwent MRgBT procedures between 2019-2022 were retrospectively reviewed.
