Case 2: Patient With Relapsed/Recurrent Metastatic RCC

An expert discusses the patient case of a 65-year-old woman who has presented to the emergency department with abdominal pain. The patient’s previous medical issues include a duodenal ulcer that she experienced 10 years ago. The patient is a smoker, and her current medication is lansoprazole (30 mg). After the patient begins to present worsening lower back pain, a CT scan shows lytic lesions in her thoracic spine and rounded lesion in both lungs. A biopsy of the lung lesion confirms clear cell renal cell carcinoma (RCC) with sarcomatoid differentiation.
