How would you treat a residual mediastinal mass in patients with a mediastinal germ cell tumor with an incomplete response to primary chemotherapy with BEPx4?

i.e. gross disease on scans that is too diffuse to be removed completely and/or decreasing but not normal markers Do you pursue close surveillance, second line chemotherapy, or surgical resection?

Several comments:

1. VIP is preferred over BEP for PMNSGCT if there will be consideration for extensive mediastinal resection (JCO 34:4445,2016)

2. Patient should be evaluated at a center with experienced and skilled thoracic surgical oncology to determine if patient is truly inoperable.

3. Need more information about tumor markers. Are they declining and might normalize in a few weeks or are they rising? There is still a cure rate with disease localized to the mediastinum even in the face of a rising AFP or hCG (Ann Onc 21:804, 2010)

4. if markers rising and patient truly not a candidate for resection, the ONLY chance for cure would be with high dose chemo followed by peripheral blood stem cell transplant.

5. No role for radiotherapy
