The authors tell us their “data on overall survival appeared interesting” - especially concerning "Overall survival from date of diagnosis of metastatic disease". They fail, however, to say anything about possible influences of "later Treatment for Metastases" on overall survival.<br> The only two patients who were, apparently, still alive at the end of the trial did receive either two times surgery (patient I-C14) or treatment with a protein kinase C inhibitor (patient VIII-A4).

The sustained survival of those two patients could well be attributable to the method of "later Treatment for Metastases" - as might be the case with part or all of the other patients, too.
