ABSTRACT
Following our concept of efficacy-orientated sequential polychemotherapy, we report on the results of palliative chemotherapy in 69 patients suffering from exocrine pancreatic cancer, admitted to our unit in 2004. Evaluation of tumor response was mainly based on the serum courses of the tumor markers CA 19-9 and CEA; in addition, the modern imaging methods CT or MRT, including MRCP and MR-angiography, were performed bi-monthly. The median survival of the 69 patients (65% metastasized stages) was 16 months. The median survival increased with the number of effective treatment sequences, for the whole group from 5 to 10 and 23 months in relation to 0, 1 and > 1 effective sequences respectively. The results support our concept of EOSPC in pancreatic cancer patients, compared to clinical studies following protocols with only 1 treatment sequence and median survival rates of no more than 6-9 months. Compared to the efficacy-orientated sequential polychemotherapy (EOSPC) concept, which does not exclude but also allows the inclusion of clinical trials for further evaluation of new drugs or drug combinations, the common practice looking for survival in studies following protocols with only 1 treatment sequence might represent a negative predictive factor with respect to overall survival, as can be demonstrated by a comparison of our data with relevant recent literature. Our results further indicate that the interest of the clinicians and companies should not be focused only on first-line therapies, but also on 2nd- and 3rd-line strategies, as in our patients a second- and third-line therapy could be started in 73% and 68% of the patients respectively.
