Oral capecitabine in gemcitabine-pretreated patients with advanced pancreatic cancer.
ABSTRACT To date, no standard regimen for salvage chemotherapy after gemcitabine (Gem) failure has been defined for patients with advanced pancreatic cancer (PC). Oral capecitabine (Cap) has shown promising activity in first-line chemotherapy trials in PC patients.
Within a prospective single-center study, Cap was offered to patients who had already received at least 1 previous treatment regimen containing full-dose Gem (as a single agent, as part of a combination chemotherapy regimen or sequentially within a chemoradiotherapy protocol). Cap was administered orally at a dose of 1,250 mg/m(2) twice daily for 14 days followed by 7 days of rest. Study endpoints were objective tumor response rate by imaging criteria (according to RECIST), carbohydrate antigen 19-9 (CA19-9) tumor marker response, time to progression, overall survival and toxicity.
A median of 3 treatment cycles (range 1-36) was given to 39 patients. After a median follow-up of 6.6 months, 27 patients were evaluable for response: no complete or partial responses were observed, but 15 patients (39%) had stable disease. A CA19-9 reduction of >20% after 2 cycles of Cap was documented in 6 patients (15%). Median time to progression was 2.3 months (range 0.5-45.1) and median overall survival (since start of Cap treatment) was 7.6 months (range 0.7-45.1). Predominant grade 2 and 3 toxicities (per patient analysis) were hand-foot syndrome 28% (13% grade 3); anemia 23%; leg edema 15%; diarrhea 13%; nausea/vomiting 10%, and leukocytopenia 10%.
Single-agent Cap is a safe treatment option for Gem-pretreated patients with advanced PC. Further evaluation of Cap in controlled clinical trials of Gem-pretreated patients with advanced PC is recommended.

ABSTRACT: Acinar cell carcinoma (ACC) of the pancreas is a rare tumor, and many aspects remain unclear because no large-scale clinical studies have been conducted. The present study investigated the clinical characteristics, treatment, and therapeutic outcomes of 115 patients registered in the Pancreatic Cancer Registry of the Japan Pancreas Society, and therapeutic plans were reviewed. Although ACC has been associated with advanced stage and poor prognosis, this tumor was resectable in 76.5% of the patients, and the 5-year survival rate after resection was favorable, being 43.9%. Confirming the diagnosis of ACC preoperatively is difficult, but this diagnosis should be kept in mind while planning surgery for ordinary pancreatic cancer. Once the diagnosis has been confirmed, a possibility of surgical resection should be pursued to achieve better prognosis. If ACC is unresectable or recurrent, chemotherapy is likely to prove useful. Multidisciplinary therapy centering on the role of surgery will need to be established.Pancreas 08/2007; 35(1):42-6. · 3.01 Impact Factor

ABSTRACT: This study evaluated the clinical activity and toxicity of combination chemotherapy with irinotecan and oxaliplatin in patients with advanced pancreatic cancer that had progressed despite > or =1 course of a gemcitabine-containing regimen. Thirty patients with metastatic pancreatic cancer and Karnofsky performance status > or =70 received oxaliplatin 60 mg/m2 on days 1 + 15 and irinotecan 60 mg/m2 on days 1 + 8 + 15 every 4 weeks. Patients were assessed on the basis of clinical benefit response, changes in serum tumour marker CA 19-9, objective tumour response, time to progressive disease (TTP), and survival. Six patients (20%) had clinical benefit response (median duration of 7.2 months). CA 19-9 levels were reduced > or =50% from baseline in 8 patients (26%) and remained stable in 8 patients. CT scans revealed that 3 patients (10%) had a partial response and 7 (23%) had stable disease. Two patients (7%) were down-staged and underwent surgery. Median TTP was 4.1 months, median survival was 5.9 months and the 1-year survival rate was 23.3%. The most serious adverse events were grade 3-4 leukopenia in 2 patients (6%), grade 3 neuropathy in 2 (6%) and grade 3 diarrhoea in 1 (3%). Chemotherapy with irinotecan and oxaliplatin is an active and well-tolerated combination in patients with advanced pre-treated pancreatic cancer.Oncology 01/2004; 67(2):93-7. · 2.61 Impact Factor

ABSTRACT: The present study was conducted to evaluate the efficacy and safety of the combination of Oxaliplatin, Leucovorin and 5-FU as second line therapy, following relapse to Gemcitabine, in patients with advanced adenocarcinoma of the pancreas. Patients with advanced pancreatic cancer previously treated with Gemcitabine were included in the study. All patients had histologically or cytologically confirmed adenocarcinoma of the pancreas that was unresectable, locally advanced or metastatic. Treatment consisted of Oxaliplatin 50 mg/m(2) (2-hour iv infusion), followed by Leucovorin 50 mg/m(2) (i.v. bolus) and 500 mg/m(2) 5-FU (1-hour iv infusion), administered weekly, until unacceptable toxicity or disease progression. Objective tumour response and toxicity were evaluated according to World Health Organisation (WHO) criteria. A total of 30 patients, 20 men and 10 women, median age 63 years (range 52-71 years) and Karnofsky Performance Status (PS) of > or =50 entered the study. The majority of patients (96%) had locally advanced disease. A total of 380 doses of chemotherapy were delivered, a median of 12 doses per patient. Partial responses were observed in 7 patients (PR 23.3%), stable disease in 9 (SD 30.0%), while 14 patients progressed (PD 46.7%). Improved PS was observed in 18 (42.8%) patients. Patients that had responded to first-line Gemcitabine treatment were found more likely to respond or stabilize their disease with second-line treatment. The median duration of response was 22 weeks, and median overall survival was 25 weeks, Grade 3/4 toxicity expressed per chemotherapy dose included leukopenia 16%, anemia 3.2%, thrombocytopenia 3.2%, diarrhea 14.2%, fatigue 16.1% and neurotoxicity 4.2%. Eight patients (27%) suffered a febrile neutropenic event managed successfully with oral antibiotic home therapy, while 17 patients required G-CSF support. There were no treatment related deaths. The combination of Oxaliplatin, Leucovorin and 5-FU was tolerated with manageable toxicity, offering encouraging activity as second-line treatment of patients with advanced or metastatic pancreatic adenocarcinoma, previously treated with Gemcitabine. Additional studies are warranted with this regimen in Gemcitabine relapsed pancreatic cancer patients.Investigational New Drugs 09/2005; 23(4):369-75. · 2.93 Impact Factor
