ovari

ovarian cancer cancer of the ovary, one of the leading causes of cancer-related death in women in the United States. Despite advances in treatment, the survival rate has risen only slightly since 1950. Although aggressive treatment in the early stages offers the best prognosis, detection before the malignancy reaches an advanced stage is difficult.

Signs and symptoms become more apparent as the tumor grows. The first finding is usually a pelvic mass noted on pelvic examination. However, if the patient is obese or has difficulty relaxing and cooperating with the examiner, the mass may not be felt. With increased size, the tumor compresses the surrounding pelvic structures, which may cause a feeling of fullness and pain in the pelvis or abdomen, abnormal uterine bleeding, urinary complaints, dyspareunia, and later ascites. Gastrointestinal symptoms such as heartburn, nausea, and anorexia may also be associated. Diagnosis is established when the mass is found during exploratory surgery and peritoneal cytology.

A plan of treatment is developed according to the stage of the disease. The modes of therapy include total abdominal hysterectomy, bilateral salpingo-oophorectomy, and a partial or complete omentectomy. Radiation and chemotherapy are administered after surgery to destroy malignant cells remaining in the abdominal cavity.
