Long-term survival after pancreatic adenocarcinoma--often a misdiagnosis?
Prognosis of adenocarcinoma of the pancreas has remained poor, but a few patients are reported to live 5 years or longer after the diagnosis. Using the data of the Finnish Cancer Registry, we could identify only 78 patients (1.3%) who had survived for longer than 5 years after the diagnosis of pancreatic cancer among 5,837 patients diagnosed in Finland in 1975-1984. ⋯ The results suggest that the majority of patients with long-term survival following the diagnosis of pancreatic cancer have never had pancreatic adenocarcinoma. Taking a biopsy from a suspected pancreatic neoplasm and careful histological evaluation may prohibit misdiagnosis of this highly lethal disease.

Effective mobilisation of peripheral blood progenitor cells with 'Dexa-BEAM' and G-CSF: timing of harvesting and composition of the leukapheresis product.
The mini-BEAM regimen (BCNU, etoposide, cytarabine, melphalan) and its modification 'Dexa-BEAM' are effective salvage protocols for relapsed Hodgkin's disease and non-Hodgkin's lymphoma. Since many patients with relapsed lymphoma are eligible for high-dose chemotherapy with autologous stem cell rescue, we were interested in the suitability of these second line regimens for mobilising peripheral blood progenitor cells (PBPC). The kinetics of PBPC were studied in 15 patients treated with Dexa-BEAM and granulocyte colony-stimulating factor (G-CSF). ⋯ Nine patients were autografted with PBPC (15.4-213.8 x 10(4) CFU-GM kg-1) after myeloablative chemotherapy and experienced rapid and sustained engraftment (Platelets > 50 nL-1 on day +13 [9-22]). We conclude that PBPC can be mobilised effectively by Dexa-BEAM plus G-CSF. An adequate timing of PBPC collection (when the leukocyte count has exceeded 10 nL-1) and evaluation of the progenitor content of the leukapheresis products with 8G12-PE will allow to minimise the number of leukaphereses.
