Hypoxic abdominal stop-flow perfusion in the treatment of advanced pancreatic cancer: a phase II evaluation/trial.

In the past decade, some authors have reported objective responses and prolonged median survival times using hypoxic abdominal perfusion (HAP) for the treatment of advanced pancreatic cancer. However, these promising results have not been confirmed by others, making it difficult to define the effectiveness of this loco-regional chemotherapy. The aim of this study, therefore, was to evaluate the response rate, time to disease progression and overall survival following HAP treatment of 22 consecutive patients with advanced pancreatic tumors. Within the period from 1999 to 2003, 22 patients with histological diagnosis of unresectable stage III/IV pancreatic cancer, not responsive to systemic chemotherapy, were treated with mitomycin C 30mg/m(2) and cisplatin 60mg/m(2) by HAP (stop flow technique). Immediately after perfusion, hemofiltration was performed to reduce systemic side toxic effects. Responses were assessed by CT-scan 30days from the end of treatment. Minor or partial responses were confirmed by a second CT-scan 4weeks later. Following 26 treatment cycles no death or technical complications were recorded; four patients (18.2%) achieved a partial response, 2 (9.1%) a minimal response and 13 (59.1%) stable disease. The remaining 3 patients (13.6%) showed progression of the disease. The median time to disease progression was 3 months (range 1-10). The median survival time from the start of regional chemotherapy was 6 months (range 1.9-16), with a 1-year survival rate of 9%. Our data show that HAP is a relatively effective second-line treatment for advanced stage pancreatic cancer with a low complication rate. We do not concur with the opinion of others that HAP is an inactive treatment approach. However, taking into account the invasiveness of this procedure, and associated morbidity and cost, HAP would not appear to be preferable to less invasive loco-regional chemotherapeutic alternatives.

Comparison of incidence of sepsis in cancer patients that underwent systemic or loco-regional chemotherapy.

In this retrospective non controlled trial we evaluated the incidence of sepsis in cancer patients in two different periods (January-June 2003 versus January-June 2004). The main difference in these two periods was that in our oncology department we changed from systemic chemotherapy to loco-regional chemotherapy using less myelosuppressive drugs and developed the domiciliary assistance. The aim of the study was to assess the incidence of sepsis in order to demonstrate a reduction of the infection related to the change of chemotherapy. In addition, this study may be able to describe the epidemiology of sepsis in cancer patients afferent to our oncology department. The incidence of sepsis was reduced in the second period from 24.3% to 6.2%. The pathogens more frequently isolated in this study were coagulase-negative staphylococci (CNS) followed by Escherichia coli and Staphylococcus aureus. Less invasive therapy may reduce infective complication of chemotherapy. The epidemiology of sepsis may be very helpful to design empiric therapeutic protocol for febrile patients that have received chemotherapy.

Thoracic stop-flow perfusion in the treatment of refractory non small cell lung cancer.

This study was undertaken to determine the survival of patients with unresectable and refractory non small cell lung cancer (NSCLC) submitted to thoracic stop-flow perfusion (TSP). Forty-five patients with NSCLC confined to thoracic region entered the study. All 45 patients had been pretreated with some form of chemotherapy and had progression of disease. The cytostatic regimen was mitomycin 10 mg/m2, navelbine 25 mg/m2 and cisplatin 60 mg/m2. In 39/45 patients, immediately after TSP, hemofiltration was performed to reduce systemic side effects There were 16/45 responses to the first TSP (CR 0; PR 16): a response rate of 35.6%. Median time to progression was 4 months. Median survival was 7.5 months.1-year survival rate was 36.4%, 2-year survival rate was 14%, and 3-year survival rate was 5.7%.

Hepatic intra-arterial chemotherapy (HIAC) of high dose mitomycin and epirubicin combined with caval chemofiltration versus prolonged low doses in liver metastases from colorectal cancer: a prospective randomized clinical study.

A multicenter randomized study comparing high dose of mitomycin and epirubicin given as hepatic intra-arterial chemotherapy (HIAC) combined with caval chemofiltration (CF) versus low doses of the same drugs in unresectable liver metastases from colorectal cancer showed a significant improvement in the survival rate of the 20 patients treated with high dose compared to the 22 patients treated with low doses with a 1 year survival of 69% vs 39%. The median survival was 17 vs 11 months and the responses were 65% vs 33%. Toxicity was colangitis in 50% of patients considered. The extrahepatic progression was similar in the two groups (7/20 vs 8/22).

Combined irinotecan and oxaliplatin in patients with advanced pre-treated pancreatic cancer.

OBJECTIVES: 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. METHODS: 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. RESULTS: 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%). CONCLUSION: Chemotherapy with irinotecan and oxaliplatin is an active and well-tolerated combination in patients with advanced pre-treated pancreatic cancer.

Intra-arterial hepatic chemoembolization in liver metastases from neuroendocrine tumors: a phase II study.

Neuroendocrine tumors, particularly those of gastrointestinal tract origin, have a predisposition for metastasizing to the liver, causing parenchymal substitution and paraneoplastic syndrome. Lipiodol embolization combined with anticancer drugs is a recent tool in regional therapy. It has been proven that chemoembolization reduces tumor bulk and hormone levels, and that it palliates the symptoms of many patients with liver-dominant neuroendocrine metastases. Beginning in December 1988, ten patients with unresectable and chemotherapy-refractory liver metastatic neuroendocrine tumors were treated with chemoembolization based on a mixture of lipiodol, mitomycin, cisplatin, epirubicin, followed by gelfoam powder and contrast media. Toxicity encountered included: upper right quadrant pain requiring narcotics, elevation of lactate dehydrogenase, alkaline phosphatase, and transaminases. One patient had liver abscess and persistent fever for 2 weeks. We obtained two complete remissions lasting 12 and 34 months and 5 partial remissions. The median survival was 22 months. Four patients had urinary elevation of 5-hydroxyindolacetic acid (5-HIAA). They showed more than a 75% decrease in urinary secretion after treatment. In a patient with transplanted liver we noticed a partial response lasting 7 months. We conclude that chemoembolization will improve the clinical condition of a significant percentage of patients with liver metastases, that future therapy of carcinoid tumors will be based on specific tumor biology and that treatment will be customized for each individual patient combining the use of cytoreductive procedures including radiofrequency ablation, laser treatment and chemoembolization.

Gemcitabine versus FLEC regimen given intra-arterially to patients with unresectable pancreatic cancer: a prospective, randomized phase III trial of the Italian Society for Integrated Locoregional Therapy in Oncology.

Gemcitabine is considered the gold standard treatment for unresectable pancreatic adenocarcinoma. Intra-arterial drug administration had shown some interesting results in small phase II studies. In this study, patients were randomly assigned to receive gemcitabine at a dose of 1,000 mg/m2 over 30 minutes intravenously weekly for 7 weeks, followed by 1 week of rest, then weekly for 3 weeks every 4 weeks or FLEC: 5-fluoruracil 1,000 mg/m2, leucovorin 100 mg/m2, epirubicin 60 mg/m2, carboplatin 300 mg/m2 infused bolus intra-arterially into celiac axis at a 3-week interval 3 times or 5-fluorouracil 400 mg/m2 plus folinic acid 20 mg/m2 for 5 days every 4 weeks for 6 cycles. The primary endpoint was overall survival, while time to treatment failure, response rate, clinical benefit response were secondary endpoints. Sixty-seven patients were randomly allocated gemcitabine and 71 were allocated FLEC intra-arterially. Patients treated with FLEC lived for significantly longer than patients on gemcitabine (p=0.036). Survival at 1 year increased from 21% in the gemcitabine group to 35% in the FLEC group. Median survival was 7.9 months in the FLEC group and 5.8 months in the gemcitabine group. Median time to treatment failure was longer with FLEC (5.3 vs 4.2 months for FLEC vs gemcitabine respectively; p=0.013). Clinical benefit was similar in both groups (17.9% for gemcitabine and 26.7% for FLEC; p=NS). CT-scan partial response was similar in both groups (5.9% for gemcitabine and 14% for FLEC; p=NS). Toxicity profiles were different. Compared with gemcitabine, the FLEC regimen given intra-arterially improved survival in patients with unresectable pancreatic adenocarcinoma.

Intra-arterial chemiotherapy for invasive bladder cancer.

Standard treatment for transitional cell carcinoma confined to the bladder is radical cystectomy that allow to obtain an overall 5-year disease-free survival rate only of 50-70%. It has been demonstrated that intra-arterial chemotherapy produces the same survival outcomes as radical cystectomy. This study aimed to evaluate the activity and toxicity of a bladder-sparing loco-regional treatment. Five patients with transitional cell carcinoma of the bladder (4 locally advanced and 1 pelvic relapse) were treated with doxorubycin 25 mg/m2, cisplatin 40 mg/m2 and methotrexate 50 mg/m2, all infused bolus via internal iliac arteries on day 1, every three weeks. We obtained 3 complete responses, 1 stable disease and 1 progression of disease. The treatment was well tolerated with a minimal hematological toxicity and no others major toxicity. Median disease free survival was 8 months (1-17), median overall survival was 22 months (2-55). This loco-regional regimen of chemotherapy is active and safe in locally advanced bladder cancer patients and permits a prolonged good quality of life regarding the maintenance of the physiological functions of the lower urinary tract.

Molecular therapy: clinical applications. intra-arterial adenoviruses administration.

Gene therapy involves the introduction of foreign DNA into somatic cells to produce a therapeutic effect. The therapeutic gene is transferred into the tumor cells using a vector. Transfer may either be in vivo in which the DNA and vector are directly introduced into the body, or ex vivo, in which cells are removed from the body, transfected with DNA and then reintroduced into the patients. The mode of gene transfer can be classified into chemical, physical and viral (1). Viruses are the most popular vectors in clinical trials because they invade cells and manipulate the cell's machinery to make viral protein; but the immune response they provoke can rapidly destroy the viral vector or the infected cells, blocking production of the useful protein. Most nonviral vector fly under the radar of immune system, but most of them have not been as efficient as viruses in shuttling genes into cells and the genes that were delivered didn't remain active for long. Intra-arterial administration can have advantages over intravenous, and intralesion routes.

Randomised trial of gemcitabine versus flec regimen given intra-arterially for patients with unresectable pancreatic cancer.

Gemcitabine is considered the golden standard treatment for unresectable pancreatic adenocarcinoma. Intra-arte-rial drug administration had shown a deep rationale with some interesting results. In a multicenter phase III trial, we compared gemcitabine given weekly with a combination of 5-fluoruracil, leucovorin, epirubicin, carboplatin (FLEC) administered intra-arteriously as first-line therapy in unresectable pancreatic adenocarcinoma. Patients were randomly assigned to receive gemcitabine at a dose of 1,000 mg/m2 over 30 minutes intravenously weekly for 7 weeks, followed by 1 week of rest, then weekly for 3 weeks every 4 weeks or 5-fluoruracil 1,000 mg/m2, leucovorin 100 mg/m2, epirubicin 60 mg/m2, carboplatin 300 mg/m2 infused bolus intra-arteriously at three-weekly interval for 3 times. The primary end point was overall survival, while time to treatment failure, response rate, clinical benefit response were secondary endpoints. Sixty-seven patients were randomly allocated gemcitabine and 71 were allocated FLEC intra-arterially. Patients treated with FLEC lived for significantly longer than patients on gemcitabine (p=.036). Survival at 1 year was increased from 21% in the gemcitabine group to 35% in the FLEC group. Median survival was 7.9 months in the FLEC group and 5.8 months in the gemcitabine group. Median time to treatment failure was longer with FLEC (5.3 vs 4.2 months for FLEC vs gemcitabine respectively; p=.013). Clinical benefit was similar in both groups (17.9% for gemcitabine and 26.7% for FLEC; p=NS). CT-scan partial response was similar in both group (5.9% for gemcitabine and 14% for FLEC; p=NS). Toxicity profiles were different. Compared with gemcitabine, FLEC regimen given intra-arteriously, improved survival in patient with unresectable pancreatic adenocarcinoma.

Regional combined with systemic chemotherapy in unresectable biliary tract cancers: a phase II study.

Unresectable biliary tract cancers have a very poor prognosis. No good systemic chemotherapeutic regimen is available. This study aimed to evaluated the activity and toxicity of a novel approach of combined loco-regional and systemic chemotherapy. Twenty four patients with advanced or metastatic biliary tumors were treated with epiadriamycin 50 mg/m2 and cisplatin 60 mg/m2 administered bolus in proper hepatic artery on day 1, combined with systemic continuous infusion of 5-fluorouracil 200 mg/m2/day, from day 1 to day 14, every 3 weeks. The overall response rate was 8/24 (33%), including one complete response and 7 partial responses (stable disease 46%, progression 21%). The treatment was well tolerated with a minimal hematological toxicity; the major clinical problem was the deep venous thrombosis related to central venous catheter, that occurred in 5 patients (21%). Median overall survival was 14,6 months and 1-year and 2-year survival were 54% and 38% respectively. Performance status improved in 33% of patients and weight gain more than 7% was observed in 17%. This novel combined loco-regional and systemic chemotherapeutic regimen is active and safe for advanced biliary tract cancer patients.

Hypoxic pelvic perfusion with mitomycin C using a simplified balloon-occlusion technique in the treatment of patients with unresectable locally recurrent rectal cancer.

HYPOTHESIS: To evaluate the role of hypoxic pelvic perfusion in providing therapeutic options for palliation without relevant complications in a homogeneous group of patients with unresectable locally recurrent rectal cancer who are nonresponders or have disease progression after the standard treatments. DESIGN: Nonrandomized and noncontrolled phase II experimental study. SETTING: University hospital, L'Aquila, and the National Cancer Institute, Naples and Milan, Italy. PATIENTS: Eleven patients had symptomatic unresectable pelvic recurrent rectal cancer. The mean +/- SD product of the 2 maximum perpendicular diameters of the recurrent cancer was 24.2 +/- 11.0 cm(2) (range, 10-48 cm(2)). Tumor fixation to the pelvic side walls or proximal sacrum were the main criteria for unresectability. All patients were free from extrapelvic disease and had a life expectancy longer than 3 months. INTERVENTION: Patients were submitted to one course of pelvic perfusion with mitomycin C (MMC) (25 mg/m(2)) by means of a simplified balloon occlusion technique. A pharmacokinetic evaluation of the procedure was also performed. MAIN OUTCOME MEASURES: Response rate and time to disease progression were the primary endpoints; overall survival was the secondary endpoint. RESULTS: Mean +/- SD value of the ratios of pelvic MMC area under the plasma concentration curve (0 to 20 minutes) (AUC(0-20)) to systemic MMC AUC(0-20) was 13.30 +/- 6.52. During the procedures there were no technical, hemodynamic, or vascular complications, and no deaths occurred during surgery or in the postoperative period. The response rate was 36.3% (95% confidence interval [CI], 6.5%-66.1%). Pain response rate was 45.4% (95% CI, 16.6%-76.2%). Median survival was 12.2 months (range, 5.7-19.5 months). Median time to disease progression was 6 months (range, 3-8 months). Two-year overall survival was 9.1%. CONCLUSIONS: Hypoxic pelvic perfusion with MMC is a safe and good palliative treatment for patients with unresectable locally recurrent rectal cancer. Further studies are necessary to establish if a different sequence in the multimodular treatment of these patients could be more useful.

Intra-arterial chemotherapy for unresectable pancreatic cancer.

BACKGROUND: A phase II trial of a new intra-arterial chemotherapy regimen for unresectable pancreatic cancer (UPC). PATIENTS AND METHODS: Ninety-six patients with UPC were treated with intra-arterial chemotherapy at three-weekly intervals. The schedule used was FLEC: 5-fluorouracil 1000 mg/m2, folinic acid 100 mg/m2, carboplatin 300 mg/m2; epirubicin 60 mg/m2. RESULTS: The overall response rates by CT-scan evaluation were: 15% partial response (PR), 44% stable disease (SD), 17% progressive disease (PD). The overall median survival was 9.9 months, and 10.6 and 6.8 for UICC stage III and IV, respectively. Pain reduction occurred in 42% of patients. A weight gain > 7% from baseline occurred in 8% of patients. A total of 341 courses of FLEC were administered. Grade 3-4 hematological toxicity was seen in 25% of patients; ematemesis in 4%; grade 3 gastrointestinal toxicity in 3%; and grade 3 alopecia in 16%. One sudden death, a pre-infarction angina, and a transitory ischemic attack were observed. The only complication related to the angiographic procedure was an intimal dissection of the iliac artery. CONCLUSIONS: The intra-arterial FLEC regimen was well tolerated and active. It requires only one day of hospitalization. Efficacy could only be assessed in a randomized study against a gemcitabine containing regimen.
