title: Locoregional/systemic chemotherapy of locally advanced/metastasized pancreatic cancer with a combination of mitomycin-C and gemcitabine and simultaneous follow-up by imaging methods and tumor markers.
abstract: Stimulated by surprising results in the first 7 patients treated with intraarterial/systemic chemotherapy with a combination of Mitomycin-C + Gemcitabine we now report on the data of 28 pancreatic cancer patients in comparison to 15 patients treated with gemcitabine alone(1000 mg/m2). Tumor response was evaluated on the basis of imaging methods, tumor markers and life quality parameters like body weight, pains and Karnofsky index etc. Tumor markers were monthly determined, imaging methods every 1-3 months. The locoregional/systemic approach included 3 week cycles with i.a. application of mitomycin-C + gemcitabine on day 1 and i.v. application of gemcitabine on days 8 and 15. The alltogether 125 cycles (mean 4 cycles per patient) resulted in 43% PR (n = 12), 1 CR (3%), 255 MR, 11% SD and 18% PD in the imaging methods and 20% CR, 60% PR, 4% MR and 12% SD in the course of the relevant tumor markers. Progression free survival amounted to a median of 7.5 (6) months defined by imaging methods (tumor markers). Second line treatments following new progress after effective locoregional approach with gemcitabine or a combination of gemcitabine + oxaliplatin did not result in a new tumor regression. However, third line therapy trials in 3 patients with high dose 5-FU or CPT 11 induced new antitumoral efficacy (survival of these tumors > 15, > 17 and > 28 months, n = 2 M1, n = 1 T3M0). About 75% of patients reported on a relevant benefit of life quality parameters. Side effects are on principle comparable to those of gemcitabine monotherapy, except for a tendency to a higher rate of pulmonary complications and 1 HUS observed. Even if not compared in a randomized study locoregional/systemic combined treatment modality seems to result in a higher rate of abjective tumor response defined by imaging methods as well as tumormarkers. Comparing tumor marker and imaging response to therapy CA 19-9 often showed a more rapid and subtle answer to therapy and an earlier new increase suggesting tumor markers as an essential part in the follow-up of these patients in order to optimize the patient's palliative treatment. Our results should stimulate the clinicians to rediscuss the chemosensitivity of exocrine pancreatic cancer and to perform prospective randomized studies focusing on combined gemcitabine approaches.
