ABSTRACT: This study evaluates the maximum tolerated dose (MTD) and activity of mitomycin, docetaxel, and irinotecan (MDI) regimen on metastatic pancreatic adenocarcinoma, previously treated with gemcitabine-containing chemotherapy.
Patients with less than 76 years, Karnofsky performance status > or = 60, and adequate bone marrow, kidney, and liver function were eligible for this trial. Treatment consisted of mitomycin 6 mg/m2 day 1, docetaxel and irinotecan on days 2 and 8 with escalating doses, every 4 weeks. Dose levels were level 1:30 and 70 mg/m2; level 2:30 and 100 mg/m2; level 3:30 and 85 mg/m2; and level 4:35 and 85 mg/m2. Dose-limiting toxicity (DLT) was defined as grade 4 neutropenia > 7 days, febrile neutropenia, grade 4 thrombocytopenia, nausea and vomiting, or diarrhea, grade > or = 3 nonhematological toxicity, or failure to recover to grade < or = 1 toxicity by day 43, occurring during the first cycle of chemotherapy.
Between September 2001 and October 2002, 15 eligible patients, three of whom had been previously treated with two lines of chemotherapy, received 33 cycles of MDI. Toxicity consisted of grade 3 to 4 neutropenia in 23% of cycles, fatigue, diarrhea, and vomiting in 10% of cycles, and one toxic death. DLT was observed in 2 of 6 level 2 patients (one toxic death and one grade 3 fatigue), and 2 of 3 level 4 patients (one neutropenic fever and one grade 3 fatigue). Thirteen patients were assessable for response. No objective response was observed among patients treated with MTD or higher doses. Three patients had stable disease; all other patients had progressive disease. The median time to tumor progression and median survival was 1.7 and 6.1 months, respectively.
The MTD was mitomycin 6 mg/m2 day one, and docetaxel 30 and irinotecan 85 mg/m2 days 2 and 8. This regimen is inactive in metastatic pancreatic cancer.

ABSTRACT: To assess the impact on local control and survival of intraoperative radiotherapy (IORT) in resectable pancreatic adenocarcinoma.
The outcome of 127 patients surgically treated with curative intent combined with IORT was compared with the therapeutic results of 76 patients treated with surgery as exclusive treatment.
Operative mortality and morbidity were similar in IORT and no-IORT patients. In 49 patients with locally limited disease (Stage I-II; LLD), IORT (n = 30) reduced the local failure rate and significantly prolonged time to local failure (TTLF), time to failure (TTF), and overall survival (OS) with respect to surgery alone (n = 19). The multivariate analyses, stratifying patients by age, tumor grade, resection margins, chemotherapy, and external-beam radiotherapy use, confirmed the independent impact of IORT on outcome. In patients with locally advanced disease (Stage III-IVA; LAD), IORT had an impact on local failure rate and on TTLF when combined with beam energies of greater than 6 MeV, whereas no effect on TTF and OS was observed.
IORT did not increase operative mortality and morbidity and achieved a significant improvement in local control and outcome in patients with LLD. In patients with LAD, beam energies greater than 6 MeV prolonged TTLF.

ABSTRACT: To evaluate the efficacy and toxicity of a cisplatin, epirubicin, gemcitabine, and fluorouracil (PEF-G) schedule on stage IV pancreatic adenocarcinoma.
Patients < or = 70 years, with no prior chemotherapy and with bidimensionally measurable stage IV pancreatic adenocarcinoma, Eastern Cooperative Oncology Group performance status < or = 2, and adequate bone marrow, kidney, and liver function were eligible for this trial. Eligibility criteria for clinical benefit assessment were pain with at least a daily analgesic consumption of two nonsteroidal anti-inflammatory drugs or Karnofsky performance status between 50 and 70. Treatment consisted of 40 mg/m2 each of cisplatin and epirubicin day 1, gemcitabine 600 mg/m2 on days 1 and 8 every 4 weeks, and fluorouracil 200 mg/m2/d as a protracted venous infusion.
Between April 1997 and April 1999, 49 patients from a single institution were eligible for the study. Altogether, 203 cycles (median, four cycles) of PEF-G were delivered. The objective response rate was 58% in 43 assessable patients and 51% in the intent-to-treat population. Fourteen patients had stable disease. Grade 3 or 4 World Health Organization neutropenia occurred in 51% of cycles, thrombocytopenia in 28%, anemia in 7%, stomatitis in 5%, and diarrhea, and nausea, and vomiting in 2%. The median duration of response was 8.5 months. The median time to tumor progression was 7.5 months. The median survival was 11 months in the assessable population and 10 months in the intent-to-treat population. Clinical benefit was achieved in 22 (78%) of 28 assessable patients.
PEF-G is a well-tolerated and safe regimen; it obtained a very high rate of durable responses and deserves further evaluation in a phase III trial.

ABSTRACT: The optimum conventional radiotherapy in glioblastoma multiforme patients has not been clearly defined by prospective trials. To better characterize a standard radiotherapy in glioblastoma multiforme, the impact on survival of different fields and doses was analyzed in a retrospective single center series.
One hundred and forty-seven patients with glioblastoma multiforme, submitted to biopsy only (n = 15), subtotal (n = 48) or total resection (n = 82) and who completed the planned postsurgical radiotherapy, were considered. The median age was 57 years, the male/female ratio 1.5/1, and the performance status > or =70 in 76%. Whole brain irradiation, followed by a boost to partial brain, was used in 75 cases with a whole brain dose of 44-50 Gy (median, 46) and a partial brain dose of 56-70 Gy (median, 60 Gy). Partial brain irradiation alone was used in 72 patients with a dose of 56-70 Gy (median, 61 Gy). Ninety-eight patients received 56-60 Gy (median, 59 Gy) to partial brain whereas 49 patients received 61-70 Gy (median, 63 Gy).
There was an almost significantly longer survival in patients irradiated to the partial brain alone with respect to those also receiving whole brain radiotherapy (P = 0.056). Doses >60 Gy significantly prolonged survival (P = 0.006). Multivariate analysis confirmed that the impact on survival of radiation dose was independent of age, performance status, extent of surgery, field of irradiation and the use of chemotherapy. The extent of irradiation field was not independently related to improved survival.
Our retrospective findings suggest that we reflect on the adequacy of the current standard irradiation parameters. Well-designed prospective trials are necessary to standardize the radiotherapy control group in patients with glioblastoma multiforme to be compared in phase III trials with innovative therapeutic approaches.
