Background: Sentinel lymph node biopsy (SNB) using radioisotopes is a standard method for assessing axillary lymph node status in patients with breast cancer. Although preoperative lymphoscintigraphy can estimate the number of sentinel lymph nodes (SNs), multiple radioactive SNs are often identified, even when lymphoscintigraphy reveals only one SN. Importantly, metastases are not always observed in the most radioactive SN (hottest SN).

Prostate cancer (PCa) is a clinically heterogeneous disease. Predicting clinically significant PCa with low-intermediate prostate-specific antigen (PSA), which often includes aggressive cancers, is imperative. This study evaluated the predictive accuracy of deep learning analysis using multimodal medical data focused on clinically significant PCa in patients with PSA ≤ 20 ng/mL.

This review article investigates the relationship between mitochondrial dysfunction and cancer progression, emphasizing the metabolic shifts that promote tumor growth. Mitochondria are crucial for cellular energy production, but they also play a significant role in cancer progression by promoting glycolysis even under oxygen-rich conditions, a phenomenon known as the Warburg effect. This metabolic reprogramming enables cancer cells to maintain an alkaline internal pH and an acidic external environment, which are critical for their proliferation and survival in hypoxic conditions.

Article Synopsis
  • Peritoneal washing cytology (CY) is primarily used for staging pancreatic cancer and assessing intraperitoneal status for better prognosis predictions.
  • This study explored using deep learning techniques like Vision Transformer (ViT) and Convolutional Neural Network (CNN) to analyze CY specimen images from 88 patients to predict their 1-year survival rates.
  • The findings revealed that both AI models had high accuracy in prognosis prediction, with ViT being slightly more effective, and identified neutrophils as a potential negative prognostic marker for these patients.

We herein report a 47-year-old man who presented with progressive paraparesis. Imaging revealed a right upper pulmonary nodule, massive bilateral adrenal metastases, thoracolumbar vertebral osteolysis, and subcutaneous nodules. A biopsy of the right buttock nodule revealed a poorly differentiated metastatic carcinoma with high programmed cell death-ligand 1 expression and extensive chromosomal rearrangements.
