Ovarian cancer is the gynecological malignancy with highest mortality rate. Due to late detection and easy recurrence, 5-year survival rate of advanced ovarian patients less than 30%. The current standard treatment for includes platinum-based combination therapy. Most achieve clinical remission; however, short-term recurrence still high. For recurrent cancer, who are unwilling receive chemotherapy or cannot tolerate after multiple lines chemotherapy, "chemotherapy-free" may be appropriate....

Malignant and premalignant ocular surface tumors (OSTs) can be sight-threatening or even life-threatening if not diagnosed treated promptly. Artificial intelligence holds great promise for the early detection of these diseases. However, training traditional convolutional neural networks (CNNs) this task presents challenges due to lack large, well-annotated datasets containing OST images labeled according histopathological results. Here, we introduce pretrained model (OSPM), a domain-specific...

Brain metastasis (BM) is a poor prognostic factor for non-small-cell lung cancer (NSCLC). Recent studies have shown that oral epidermal growth receptor (EGFR) tyrosine kinase inhibitors (TKIs) were effective BM from NSCLC with EGFR mutation. However, the relationship between mutations and prognosis of patients remains to be determined. In this study, we investigated impact mutation status on survival NSCLC. One hundred six retrospectively reviewed. Thirty-three subjects (24.3 %) confirmed an...
