ABSTRACT
Leptomeningeal metastases are lesions of brain and/or spinal cord sheaths by tumor cells. They occur in 5% of patients with solid tumors, although autopsies reveal these lesions much more often (10-20% of cases). Leptomengeal metastases are an unfavorable prognostic factor. Despite the modern NCCN treatment standards, including intrathecal therapy (ITT), such patients receive only irradiation of the entire brain and/or spinal cord in most cases. OBJECTIVE: To evaluate the effectiveness of ITT in patients with leptomeningeal metastases in breast cancer. MATERIAL AND METHODS: Twenty-five patients with breast cancer and leptomeningeal metastases underwent intrathecal administration of methotrexate between 2016 and 2022. Intrathecal chemotherapy was administered through lumbar puncture. We performed an intensive course (intrathecal methotrexate 15 mg 2 times a week for 1 month (8 injections), then intrathecal methotrexate 15 mg 1 time a week (4 injections), and then 15 mg 1 time a month until progression or unacceptable toxicity). RESULTS: The median duration of ITT was 2.5 months. Complete neurological responses were observed in 3 out of 25 (12%) patients, partial neurological response - in 15 out of 25 (60%) patients, progression of neurological symptoms - in 7 (28%) patients. The number of complete cytological responses was observed in 6 out of 25 (24%) patients. The median overall survival after ITT was 6.7 months. CONCLUSION: Effectiveness of ITT is confirmed by higher quality of life (72% of patients), complete cytological responses (24%) and improvement in neuroimaging data. This is an important criterion for severe patients with limited treatment options. First-stage ITT before whole-brain irradiation is preferable, as this approach increases overall survival by 3 months. Undoubtedly, ITT is a treatment option that can be used in routine clinical practice for lesions of brain and spinal cord sheaths.

OBJECTIVE: To evaluate the feasibility of ultrasound in diagnosis of chronic paracolic inflammatory mass in patients with diverticular disease. MATERIAL AND METHODS: We analyzed ultrasonic findings in 216 patients with chronic inflammatory complications of colonic diverticular disease. Chronic paracolic inflammatory mass as the most common and significant chronic complication of diverticular disease was analyzed in 116 patients. Ultrasonic findings were compared with specimen assessment, intraoperative data, irrigoscopy, colonoscopy, endoscopic ultrasound and computed tomography data. RESULTS: Sensitivity of ultrasound for diagnosis of chronic paracolic inflammatory mass was 76,7%, specificity - 100%, overall accuracy - 87,5%. CT and endoscopic ultrasound were the most informative among different diagnostic tools (sensitivity 79,6% and 77,8%, respectively). CONCLUSION: Ultrasonic examination and computed tomography are the most valuable methods for diagnosis of chronic paracolic inflammatory mass in patients with diverticular disease. Ultrasound is a first-line method for diagnosis and follow-up of complicated diverticular disease due to its availability, safety and unnecessary special preparation of patients.

The article describes a clinical case of successful chemotherapeutic and radiation treatment of a patient with breast cancer and metastases to the brain and meninges and with a pronounced neurological deficit. The patient underwent combined treatment (whole brain radiation with TBD of 30 Gy and local radiation of a metastasis with TBD of 15 Gy associated with capecitabine therapy) with continued administration of capecitabine until improvement. A partial metastasis reduction by 50% and complete regression of the neurological deficit were observed. Disease-free period was 1 year and 10 months, and the overall survival amounted to 2 years.
