Investigations were made at surgical treatment stages in 102 cancer patients (mean age 72 +/- 5.8 years) at high cardiovascular risk, who received continuous therapy that reduced heart rate and blood pressure, in order to compensate for the course of coronary heart disease and arterial hypertension. The time course of changes in the major circulatory and metabolic parameters was analyzed in patients during operations on the abdomen and small pelvis while using three different multimodal anesthetic techniques (general intravenous anesthesia-based diazepam, propofol, fentanyl, ketamine; sevofluorane-based inhalational; combined epidural and intravenous one). The advantages and limitations of the above methods were shown in patients on cardio- and vasotropic therapies. Correcting modes (transesophageal atrial pacing, morning-dose drug withdrawal) for its possible related bradycardiac and hypotensive disorders, which reduce a risk of perioperative cardiovascular complications, are set forth.

Immune checkpoint inhibitors have improved the treatment of metastatic renal cell carcinoma (RCC), with the combination of nivolumab (NIVO) and ipilimumab (IPI) showing promising results. However, not all patients benefit from these therapies, emphasizing the need for reliable, easily assessable biomarkers. This multicenter study involved 116 advanced RCC patients treated with NIVO + IPI across nine oncology centers in Poland.

Chemotherapy-drug interactions (CDIs) pose significant challenges in oncology, affecting treatment efficacy and patient safety. Despite their importance, there is a lack of validated tools to assess oncologists' knowledge of CDIs. This study aimed to develop and validate a comprehensive questionnaire to address this gap and ensure the reliability and validity of the instrument.

Currently, the World Health Organization (WHO) grade of meningiomas is determined based on the biopsy results. Therefore, accurate non-invasive preoperative grading could significantly improve treatment planning and patient outcomes. Considering recent advances in machine learning (ML) and deep learning (DL), this meta-analysis aimed to evaluate the performance of these models in predicting the WHO meningioma grade using imaging data.
