Anaplastic cell tumors generally have a 5-year survival rate of 100% for Stage I, 85% for Stage II, 79% for Stage III, and 71% for Stage IV after regular hospital treatment. The 30-year survival probability of anaplastic cell tumor is related to tumor stage, age, and physical condition. Anaplastic cell tumors are ovarian malignant tumors that are common during puberty and childbearing years and are usually unilateral. The tumor is round or oval, solid, medium-sized, and may have a smooth or lobulated surface and a light brown section. Microscopically, large round or polygonal cells with large nuclei and abundant cytoplasm are seen, and the tumor cells are arranged in strips or sheets, separated by a small amount of fibrous tissue, and lymphocytes may infiltrate the interstitium.
