Rectal examination shows normal tone, brown, guaiac-negative stool, and a large nodule. There is a 3/5 strength on the left and 5/5 strength on the right to dorsiflexion of the great toes.

A 25-year-old man is admitted to the hospital for chemotherapy treatment of metastatic seminoma. He presented three weeks ago with painless testicular mass and underwent orchiectomy, yielding a diagnosis of seminoma. A CT scan of the abdomen confirmed metastatic disease to the retroperitoneal lymph nodes. His temperature is 37.1o C (98.8oF). He is well appearing, heart is regular without murmurs, lungs are clear, and abdomen is benign. Some postsurgical changes are present on inspection of the genitals. Laboratory studies show a leukocyte count of 6500/L, hematocrit of 45%, platelets of 359,000/L blood urea nitrogen 12 mg/dL, and creatinine of 0.6 mg/dL. Soon after his admission chemotherapy orders are finished, he states that he has changed his mind with regard to therapy and says that he now “has found God and feels that God alone will cure his disease”. What’s the most appropriate management at this time?
