Case:  A 70-Year-Old Woman Presenting With Advanced Ovarian Cancer

H & P:

  • A 70-year-old woman presents for evaluation of left-ovary mass discovered during a recent pelvic exam. She reports abdominal tenderness, urinary symptoms, and a “bloated” or “full” feeling, despite normal diet and bowel movements
  • Postmenopausal, no children

    • Fasting glucose = 95 mg/dL
    • LDL = 90 mg/dL

Imaging

  • CT with contrast of pelvis, abdomen, and chest reveals multiple peritoneal lesions and spread to outside of liver
  • Malignant ascites present

Biopsy and labs:

  • Pathology: high-grade epithelioid adenosarcoma, ovarian primary
  • BRCA1/2 status: unknown
  • CA-125: 656 U/mL

Treatment

  • She underwent hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and tumor debulking; residual disease after cytoreduction: 1.25 cm
  • Diagnosis: stage IV ovarian cancer, grade 3
  • Started on carboplatin and paclitaxel plus bevacizumab; achieved a partial response
