• Reduce HDRx doses <strong>and</strong> give something like DLI after<br />

allogeneic BMT<br />

• Treat small cell lung cancer patients<br />

• Try allogeneic BMT for breast cancer looking for graft<br />

antitumor effect<br />

• Do outpatient BMT, mini-BMT, several courses of Rodenhuis<br />

attenuated dose therapy<br />

Group's question<br />

1) Restaging in breast cancer: Now that we can identify tumor cells in <strong>marrow</strong> <strong>and</strong><br />

<strong>blood</strong> specimens from patients with stage III <strong>and</strong> even high risk stage II breast cancer,<br />

should we now restage these patients as stage IV?<br />

Author's response<br />

NO! Stage creep <strong>and</strong> its outcome consequences.<br />

i) We are already treating these patients with systemic, including high dose,<br />

cytotoxic therapy.<br />

ii) It is still not clear what extra risks these findings mean for patients receiving high<br />

dose therapy.<br />

iii) Were we to do this, the results for both stage IV (in CR or PR because of<br />

microscopically detectable tumor cells) <strong>and</strong> high risk stage Il/ni patients<br />

receiving high dose therapy would improve; i.e., this would give rise to the<br />

"Will Rogers effect."<br />

Group's question<br />

2) Chemoresistant patients: Now that we have sufficient follow-up data for patients who<br />

have failed at least two combination regimens for their malignancy <strong>and</strong> who have sub­<br />

sequently received high dose therapy, should we now stop treating these patients<br />

because of their poor DFS (
