Further evidence for prolongation of survival of pancreatic cancer patients by efficacy orientated sequential polychemotherapy (EOSPC) based on serial tumor marker determinations (CA 19-9/CEA).
The results of palliative chemotherapy in 55 patients suffering from exocrine pancreatic cancer are reported, following our concept of efficacy orientated sequential polychemotherapy (EOSPC). Tumor answer/regression was mainly analyzed on the basis of the serum courses of the tumor markers CA 19-9 and CEA. Up to four different treatment trials were tried in the individual patients. The results confirm previously published data: a prolongation of survival in relation to the number of effective treatments (CR/PR/MR/SD vs. PD). The median survival of the whole group of patients (n=55, including n=39 patients with distant metastasis) was 12 months. The results support our concept of EOSPC in pancreatic cancer patients in order to improve survival. Furthermore, the data should stimulate attention not only on new and potentially more effective 1st- line regimens, but also to effective 2nd- and/or 3rd-line treatments. Moreover, the results should encourage clinicians to rediscuss the actual concepts of prospective therapeutical trails mainly based on analyzing the effects of single agents or drug combinations on survival. Furthermore, a comparison of 1st-line treatments with gemcitabine as monotherapy, and in combination with mitomycin-C, confirms that the combination of gemcitabine + mitomycin-C seems to be more active than gemcitabine monotherapy and that this combination might also be of value as 2nd-line therapy after gemcitabine monotherapy.
