    Addressing these high-risk positive margin sites with adjuvant brachytherapy after surgical resection is a good option to deliver a high dose of radiation to the R1 resection site while sparing the adjacent critical organs at risk. Herein, we present a case report of two patients with persistent or recurrent anal cancer

    Journal:  Long-Term Urinary Toxicity Follow-Up of Combined External Beam Radiation and Cs-131 LDR Brachytherapy Boost for Prostate Cancer. (Pubmed Central) -  Oct 3, 2023   
    Long-term patient-reported clinically significant decreases in urinary function and urinary incontinence mean EPIC scores occurred up to 18 months following combined external beam radiation and Cs-131 prostate brachytherapy and returned to baseline at 24 months, while clinically significant decrease in urinary irritability/obstructive mean scores occurred at 9 months and returned to baseline at 12 months. At 42 months follow-up, mean urinary domain scores improved from pre-treatment baseline in 15-30% of patients.

    Outcomes of Brain Metastases with Suspicious Imaging Undergoing Resection to Evaluate for Radionecrosis vs. Tumor Progression (Hall B2; In Person Only; Screen: 3) -  Aug 22, 2023 - Abstract #ASTRO2023ASTRO_626;    
    We recommend cautious monitoring of possible progression after radiosurgery, with consideration of resection for continuous progression, as a significant proportion of radiographic progression are ultimately pure RN. Management determined by pathology (observation for RN; additional radiation for confirmed tumor) leads to excellent control.

    Cs-131 brachytherapy demonstrated a favorable safety and efficacy profile characterized by high rates of local control for all treated pathologies. The concept of brachytherapy has seen a resurgence given the excellent results when Cs-131 is used as a source.

    Review, Journal:  Cesium-131 brachytherapy for the treatment of brain metastases: Current status and future perspectives. (Pubmed Central) -  Feb 27, 2023   
    Further analyses have demonstrated superior cost-effectiveness and quality-of-life improvement ratios of cesium-131 brachytherapy than adjuvant stereotactic radiosurgery. Cesium-131 brachytherapy is a safe and effective post-surgical treatment option for brain metastases with associated clinical and cost-effectiveness benefits in appropriately selected patients.

    Journal:  Feasibility of collagen matrix tiles with cesium-131 brachytherapy for use in the treatment of head and neck cancer. (Pubmed Central) -  Nov 15, 2022   
    The use of LITT in combination with brachytherapy remains an option for salvage therapy in patients with recurrent meningioma that provides durable local control of tumor. We present a feasibility and concept cadaveric study using a collagen matrix with Cesium-131 demonstrating preliminary evidence to support its ease of use, decreased time to implantation, and decreased dose delivered to the carotid artery.

    With > 1.5 years of follow-up, intraoperative brachytherapy with commercially available Cs131 implants was associated with favorable local control and toxicity profiles. Weak correlation between preoperative tumor geometry and implanted tiles highlights a need to optimize planning criteria.

    Journal:  Patient-specific dose correction for prostate postimplant evaluation with flexible timing of postimplant imaging. (Pubmed Central) -  Sep 8, 2022   
    The postimplant dose calculation based on the proposed inverse power law for prostate seed implants with edema has improved the accuracy of postimplant dosimetry with accurate and patient-specific dose corrections accounting for prostate size, edema half-life, and postimplant imaging times. Optimal times for postimplant imaging have been accurately determined, and high accuracy of postimplant dose calculation can be achieved for both optimal imaging times and non-optimal imaging times.

    Ongoing trials are evaluating long-term locoregional tumor control and future studies should analyze its role in multimodal systemic tumor management. A short course of perioperative low-dose prednisone was associated with less severe worsening in urinary symptoms by the EPIC questionnaire at the 0.5-1.0-month timepoint suggesting some improvement in acute urinary quality of life, although differences did not remain statistically significant at 3 months.

    Future studies may elucidate which IR patients would benefit from treatment intensification. Cesium-131 brachytherapy resulted in good local control and acceptable rates of symptomatic AREs and surgical complications in this heavily pretreated cohort, and it may be a reasonable salvage adjuvant treatment for this patient population.

    The first reported case of GammaTile intraoperative brachytherapy during awake craniotomy supports the safety and feasibility of this treatment strategy. This case indicates that for patients with tumors adjacent to eloquent cortex, awake craniotomy can allow for custom implantation of intraoperative brachytherapy following maximum safe resection.

    Clinical, Journal:  Comparison of Three Groups of Patients Having Low Dose Rate Prostate Brachytherapy: Prostate-Specific Antigen Failure and Overall Survival. (Pubmed Central) -  Oct 30, 2021   
    The median PSA value at 60 months was 0.11 ng/ml. There were only a few PSA failures in the three groups of cases, nonetheless, the Cs-131 had the fewest.  Conclusions One attractive option for men with early-stage prostate cancer is interstitial brachytherapy. The use of the shorter-acting Cs-131 isotope may be expected to have dose-related side effects that resolve more rapidly. This series suggests a trend for improved PSA control outcomes for Cs-131 patients compared with I-125 and Pd-103.

    Cesium-131 brachytherapy in this heavily pre-treated cohort resulted in good local control and an acceptable rate of symptomatic adverse radiation effect and toxicity and may be a reasonable treatment option for this select population. In a cohort of low- and intermediate-risk prostate cancer patients treated with cesium-131 PB, the rate of BCR in men with baseline IC was low and baseline IC was not associated with a higher risk of BCR.

    Short- and long-term urinary, sexual, and bowel quality of life, as well as long-term biochemical control were comparable between I and Cs. This report therefore supports the continued use of Cs as an effective and comparable alternative isotope.

    In a cohort of LR and IR prostate cancer patients treated with Cs-131 PB, the rate of BCR in men with baseline IC was low and baseline IC was not associated with a higher risk of BCR. The present study demonstrates that prostate brachytherapy with Cs achieves excellent long-term biochemical control.
