BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) are common side effects, classified according to timing and severity. Conventional agents such as dexamethasone are effective but have various side effects. For moderately emetogenic chemotherapy, dexamethasone-sparing antiemetic therapies have been developed to minimize these side effects. This systematic review evaluated the efficacy and safety of dexamethasone-sparing antiemetic therapy for highly emetogenic chemotherapy (HEC)...

BACKGROUND: Cisplatin (CDDP) is an anticancer drug used to treat several types of cancer. CDDP-induced nephrotoxicity (CIN) is a serious adverse effect of CDDP treatment. Although magnesium sulfate (Mg) premedication has been proven to prevent CIN, the relationship between Mg dosage and its preventive effects on CIN are unknown. Therefore, we have evaluated this relationship using meta-analysis and meta-regression analysis to optimize cancer chemotherapies, including CDDP. METHODS: We selected candidate studies, generated a forest plot to evaluate the preventive effects of Mg on CIN, and performed subgroup analyses...

REVIEW
Current status and prospects of breast cancer imaging-based diagnosis using artificial intelligence.
Chikako Sekine, Jun Horiguchi
Breast imaging has several modalities, each unique in terms of its imaging position, evaluation index, and imaging method. Breast diagnosis is made by combining a large number of past imaging features with the clinical course and histological findings. Artificial intelligence (AI), which extracts the features from image data and evaluates them based on comprehensive analysis, has been making rapid progress in this regard. Many previous studies have demonstrated the usefulness and development potential of AI, such as machine learning and deep learning, in breast imaging...
