Exploratory Study on HER2 Detection Method and Positive Threshold for High-grade Serous Adenocarcinoma of the Ovary
Ovarian cancer is the most lethal gynecological malignancy, and 70% of ovarian cancer patients are diagnosed late at the time of new diagnosis. Even after systematic treatment, 75% of patients still relapse within 3 years and 70% die within 5 years. The survival prognosis of platinum resistant and refractory ovarian …
Effects of Primary Open-angle Glaucoma on Visual-motor Coordination
Commonly used visual function assessments in glaucoma diagnosis and treatment-such as visual acuity, visual field, and contrast sensitivity-do not directly capture the impact of the disease on patients' daily abilities. While questionnaires can evaluate this impact from the patient's perspective, they are subject to individual biases and inconsistent evaluation standards. …
