You Make the Call Each month in “You Make the Call,” we’ll pick a challenging clinical question submitted through the Consult-a-Colleague program and post the expert’s response. But, what would YOU do? We’ll also pose a submitted question and ask you to send your responses. See how your answer matches up to the experts in the next print issue. This month, George P. Canellos, MD, advises on treatment options for a young patient with Hodgkin lymphoma and bleomycin lung injury. Clinical Dilemma: A 23-year-old male patient with nodular sclerosis classical Hodgkin lymphoma – stage IIIb with bulky mediastinal disease, International Prognostic Index score of 3 points. He has received two cycles of ABVD, resulting in a 21 percent decrease in carbon monoxide diffusing capacity (DLCO) and symptomatic bleomycin lung toxicity. An 18-fluorodeoxyglucose (FDG) positron emission tomography (PET) scan after two cycles revealed two persistent areas of FDG avidity: persistent disease versus disease secondary to inflammation from bleomycin lung damage. His symptoms did improve with steroid treatment. Subsequently, he received four cycles of ABVD. A PET scan performed after four cycles of chemotherapy was negative, and we are currently awaiting a post-treatment PET scan. Experts Make the Call George P. Canellos, MD William Rosenberg Professor of Medicine Harvard Medical School Dana-Farber Cancer Institute Boston, MA I would say you did the right thing by giving ABVD to complete the chemotherapy regimen. Because the patient is only 23 years old, I would be cautious about radiation therapy – given the high risk of long-term cardiac toxicity. If he is indeed PET-negative, there is a chance that he is already cured. However, there is a 10 to 20 percent chance of disease recurrence. But, being that he has stage IIIb disease, the patient’s disease could recur anywhere. I would follow the patient closely with CT or PET/CT scans repeated at six months. If the disease recurs only in the mediastinum, then a cycle of ABVD followed by radiation therapy to the mediastinum – if this is the only site of relapse – would be advisable. In a PET-negative circumstance, I would say six months is a liberal interval of time, but I assume the patient will be seen sooner on a clinical basis. In fact, one could say that the longer the PET remains negative, the less likely a relapse will occur. It would worry me if an early mediastinal relapse occurred because it was not confined to that site and the disease may recur in other sites over time.

Next Month’s Clinical Dilemma: I have a 32-year-old male patient with no cardiovascular risk factors who had what looks to be an idiopathic renal infarct. The radiologist feels that the infarct was likely arterial in origin, but no source of the clot has been found. Results from the CT angiography of the entire aorta and embolic work-up (including 48-hour Holter monitoring for atrial fibrillation) have been negative to date – so have the results from my APLA/PNH/MPN work-up. In this instance, how long should anticoagulation last? I am unsure what duration to recommend because the infarct was arterial and idiopathic. Data for this circumstance seem to be scarce, and I have read that the duration should be anywhere from 6 to 12 months to indefinitely. While I am worried about recurrence – given he had this thrombosis at such a young age – I am also cognizant of the burden that lifelong anticoagulation will bring. How would you respond?
