Intraoperative radiation therapy for breast cancer-Immediate and 30-month oncological outcomes.

There is growing evidence that intraoperative radiation therapy (IORT) may be a viable option in selected patients with early breast cancer. This study reports our 4-year experience with IORT. The perioperative outcome and imaging data of all patients who underwent IORT for early breast cancer at a tertiary medical center in 2014-2018 were retrospectively retrieved. The cohort included 158 patients aged 52-84 years (mean 68) with stage I (n = 137) or II (n = 21) breast cancer. Mean applicator size was 4.13 cm; IORT added a mean of 29 minutes to the operative time. Minor wound infections (n = 18, 11.4%) requiring antibiotics and drainage were the only postoperative complication. In 25 patients (15%), postoperative mammography demonstrated a seroma (n = 22) or fat necrosis (n = 3). The risk of wound infection or a new postoperative imaging finding was unrelated to patient age, operative time, tumor size, or comorbid diabetes or obesity. After a mean of 30 months' follow-up, none of the patients who met the institutional criteria for IORT had local recurrence, regardless of age, histology, tumor grade, KI67 proliferation index, pathologic stage, Recurrence Score, or additional whole-breast irradiation or adjuvant treatment. Patients for whom a Recurrence Score was determined (n = 55, 35%) had a significantly higher tumor grade, pathologic stage, and whole-breast irradiation/adjuvant chemotherapy rate than the remaining patients. IORT may be a safe alternative to traditional external beam radiation in well-selected patients with early breast cancer, with few minor complications and good 30-month outcome.

Children and adolescents with ASD treated with CBD-rich cannabis exhibit significant improvements particularly in social symptoms: an open label study.

In recent years there has been growing interest in the potential benefits of CBD-rich cannabis treatment for children with ASD. Several open label studies and one double-blind placebo-controlled study have reported that CBD-rich cannabis is safe and potentially effective in reducing disruptive behaviors and improving social communication. However, previous studies have mostly based their conclusions on parental reports without the use of standardized clinical assessments. Here, we conducted an open label study to examine the efficacy of 6 months of CBD-rich cannabis treatment in children and adolescents with ASD. Longitudinal changes in social communication abilities and restricted and repetitive behaviors (RRB) were quantified using parent report with the Social Responsiveness Scale and clinical assessment with the Autism Diagnostic Observation Schedule (ADOS). We also quantified changes in adaptive behaviors using the Vineland, and cognitive abilities using an age-appropriate Wechsler test. Eighty-two of the 110 recruited participants completed the 6-month treatment protocol. While some participants did not exhibit any improvement in symptoms, there were overall significant improvements in social communication abilities as quantified by the ADOS, SRS, and Vineland with larger improvements in participants who had more severe initial symptoms. Significant improvements in RRB were noted only with parent-reported SRS scores and there were no significant changes in cognitive scores. These findings suggest that treatment with CBD-rich cannabis can yield improvements, particularly in social communication abilities, which were visible even when using standardized clinical assessments. Additional double-blind placebo-controlled studies utilizing standardized assessments are highly warranted for substantiating these findings.
