Abstract
Improving survival in patients with pancreatic cancer remains a formidable challenge. For the few patients with localised stages of the disease, intra-operative radiotherapy, adjuvant chemoradiotherapy and neo-adjuvant therapies remain non-validated and the survival benefit conferred by 5-fluorouracil-folinic acid adjuvant chemotherapy over radical surgery alone is still a matter of debate. Gemcitabine has recently emerged as the standard single agent in advanced stages of the disease and pharmacokinetic refinements such as the use of a fixed-dose infusion rate may further improve still rather modest result figures. At present, most efforts deal with the development of more effective doublet or triplet therapies, combining gemcitabine with either conventional cytotoxic drugs--the most promising being oxaliplatin--or more innovative, targeted therapeutic agents. Among these agents, matrix metalloprotease inhibitors and farnesyltransferase inhibitors have already undergone Phase III trials, alone or in combination with gemcitabine, with rather disappointing results. However, preclinical and Phase I and II studies of cyclooxygenase-2 or lipoxygenase inhibitors, various immunotherapeutic approaches and several tyrosine kinase inhibitors or monoclonal antibodies against growth factors or their receptors are encouraging and may provide some hope for patients with pancreatic cancer.

Abstract
OBJECTIVE The aim of this study was to evaluate the efficacy and toxicity of S-1 in patients with metastatic pancreatic cancer. METHODS Patients were required to have a histological diagnosis of pancreatic adenocarcinoma with measurable metastatic lesions, and no prior chemotherapy. S-1 was administered orally at 40 mg/m2 twice daily for 28 days with a rest period of 14 days as one course. Administration was repeated until the appearance of disease progression or unacceptable toxicity. A pharmacokinetic study was done on day 1 in the initial 8 patients. RESULTS Nineteen patients were entered into this study. Four patients (21.1%) achieved a partial response with a 95% confidence interval of 6.1-45.6%. No change was noted in 10 patients (52.6%), and progressive disease in 5 patients (26.3%). The median survival time was 5.6 months with a one-year survival rate of 15.8%. The major adverse events were gastrointestinal toxicities such as nausea and anorexia, though most of them were tolerable and reversible. There were no large differences in the pharmacokinetic parameters of S-1 in patients with pancreatic cancer and those in patients with other cancers. CONCLUSION S-1 is active and tolerated in patients with metastatic pancreatic cancer, which will be confirmed in the following large-scale phase II study.

Abstract
BACKGROUND Additional systemic treatments for locally advanced or metastatic pancreatic cancer are needed, as current treatment options produce only modest survival benefits. Rubitecan (Orathecin; Supergen Inc., Dublin, CA, http://www.supergen.com) is an orally active camptothecin derivative with demonstrated responses in patients with pancreatic cancer in early clinical trials. This phase II, open-label trial was developed to assess the safety and efficacy of rubitecan in patients with locally advanced or metastatic pancreatic cancer refractory to conventional chemotherapy. METHODS Fifty-eight patients with failed or relapsed advanced pancreatic cancer after receiving at least one prior chemotherapy regimen were enrolled to receive eight consecutive weeks of treatment with rubitecan at a dose of 1.5 mg/m2 orally on five consecutive days per week, followed by 2 days off therapy, repeatedly. The primary end point was response rate. Time to progression, overall survival, changes in CA19-9 levels, and the composite measure of clinical benefit response were evaluated as secondary end points. RESULTS Among 43 patients with measurable disease, 7% (3/43) achieved partial responses and 16% (7/43) had disease stabilization for an overall response and disease stabilization rate of 23%. All responses were confirmed by independent radiology review. Median survival was longer in responding patients than in the overall study cohort (10 months versus 3 months). Gastrointestinal and hematologic toxicities were the most commonly reported adverse events. CONCLUSION Oral rubitecan produced responses and was well tolerated by heavily pretreated patients with refractory pancreatic cancer. The overall risk-benefit profile of oral rubitecan appears promising, supporting further evaluation in phase III trials in patients with refractory and chemotherapy-naive pancreatic cancer.

Abstract
In the last decade, continued efforts in pancreas cancer research have led to the development of new, more effective therapies. Additionally, progress in understanding the molecular processes underlying the development and progression of this disease provides hope for the development of more effective treatment strategies. Recent clinical trials have provided reason for hope that novel chemotherapy combinations and molecularly targeted agents will lead to improved clinical outcomes for patients with this disease. This article will summarize the data that has led to the current standards of therapy for patients with resectable and advanced pancreatic cancer and review new treatment strategies for this disease.

Abstract
PURPOSE To evaluate response rate and toxicity of irinotecan and oxaliplatin plus fluorouracil (FU) and leucovorin (Folfirinox) in advanced pancreatic adenocarcinoma (APA). PATIENTS AND METHODS Chemotherapy-naive patients with histologically proven APA and bidimensionally measurable disease were treated with Folfirinox therapy every 2 weeks, which comprised oxaliplatin 85 mg/m(2) and irinotecan 180 mg/m(2) plus leucovorin 400 mg/m(2) followed by bolus FU 400 mg/m(2) on day 1, then FU 2,400 mg/m(2) as a 46-hour continuous infusion. Quality of life (QOL) was assessed using European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30). RESULTS Forty-seven patients were entered, and 46 received treatment. Thirty-five patients (76%) had metastatic disease. A total of 356 cycles were delivered, with a median of eight cycles per patient (range, one to 24 cycles). All patients were assessable for safety. No toxic death occurred. Grade 3 to 4 neutropenia occurred in 52% of patients, including two patients with febrile neutropenia. Other relevant toxicities included grade 3 to 4 nausea (20%), vomiting (17%), and diarrhea (17%) and grade 3 neuropathy (15%; Levi's scale). The confirmed response rate was 26% (95% CI, 13% to 39%), including 4% complete responses. Median time to progression was 8.2 months (95% CI, 5.3 to 11.6 months), and median overall survival was 10.2 months (95% CI, 8.1 to 14.4 months). Between baseline and end of treatment, patients had improvement in all functional scales of the EORTC QLQ-C30, except cognitive functioning. Responders had major improvement in global QOL. CONCLUSION With a good safety profile, a promising response rate, and an improvement in QOL, Folfirinox will be further assessed in a phase III trial.

Abstract
BACKGROUND Troxacitabine (Troxatyl) is a novel L-enantiomer nucleoside analog with activity in pancreatic cancer xenograft models. PATIENTS AND METHODS Troxacitabine 1.5 mg/m(2) was administered by 30-min infusions daily x5 every 4 weeks to 54 patients with advanced pancreatic cancer. Patients were evaluated for objective tumor response, time to tumor progression (TTP), changes in tumor marker CA 19-9, survival, safety, pain, analgesic consumption, Karnofsky performance status and weight change. RESULTS Median TTP was 3.5 months (95% CI 2.0-3.8), median survival 5.6 months (95% CI 4.9-7.4), and the 1 year survival rate 19%. Best responses were stable disease in 24 patients with eight patients having stable disease for at least 6 months (15%). A 50% or greater decrease in CA 19-9 was seen in seven of 44 assessed patients (16%). Grade 3 and 4 neutropenia were observed in 37% and 30% of patients with one episode of febrile neutropenia. The most common drug-related non-hematological toxic effects reported were cutaneous, with 22% and 6% of patients reporting grade 2 and 3 skin rash, respectively and 4% grade 2 hand-foot syndrome. CONCLUSION Troxacitabine administered by a bolus daily x5 monthly regimen has modest activity in advanced pancreatic adenocarcinoma.

Abstract
Pancreatic cancer remains a fearsome disease. New insights into the molecular pathogenesis may influence choice of treatment modalities and provide avenues for novel therapeutic strategies for testing in the clinic. The survival rate of patients with all stages of disease is poor and clinical trials are appropriate alternatives for treatment and should be considered. Surgical resection, when possible, remains the primary treatment modality and can result in long-term cure. Less invasive techniques such as laparoscopy may reduce the rate of unnecessary laparotomies. The role of adjuvant therapy is re-emerging. Patients with unresectable and metastatic disease are incurable and optimal palliation is the goal. These patients may benefit from palliative bypass of biliary or duodenal obstruction if symptomatic. Pain associated with local tumour infiltration may be palliated with radiation, with or without chemotherapy, or with coeliac nerve blocks or local neurosurgical procedures. Chemotherapy with gemcitabine has modest objective response rates but has been shown to improve symptoms.

Abstract
Despite chemotherapy, median survival of patients with advanced pancreatic cancer (APC) remains poor. Gemcitabine (GEM) remains standard treatment. Numerous phase II studies have suggested that combination therapies may improve response rates. Mitomycin C (MMC) when used as a single agent may have response rates comparable to other cytotoxic drugs. Therefore, MMC could be an interesting drug to be combined with GEM. This study aimed to assess the feasibility, toxicity and efficacy of GEM combined with MMC in patients with APC. Between April 1997 and January 2002, 55 consecutive patients were treated with GEM 800 mg/m2 i.v., days 1, 8 and 15, and MMC 8 mg/m2 i.v., day 1, every 4 weeks in an outpatient setting. Patient characteristics included: M/F 34/21, median age of 58 years, ECOG PS 0-2. A median of 3 cycles was administered. The most frequent toxicity was thrombocytopenia grade III/IV in 54% of patients. Ten patients experienced dyspnea+/-X-ray-proven pneumonitis (n=2). One of these patients developed a hemolytic uremic syndrome after the sixth application of MMC. There was one early death as a consequence of a stroke. The objective response rate was 29% (95% confidence interval: 17-43). Eighteen patients had stable disease resulting in an overall tumor growth control of 62%. Time to progression was 4.7 months and median overall survival was 7.25 months. We conclude that, except for thrombocytopenia, the combination of GEM and MMC is well tolerated. These results compare favorably to single-agent chemotherapy with GEM or the combination of 5-fluorouracil plus MMC. Furthermore, this regimen is cost-effective and, since it can be given on an outpatient basis, contributes to the quality of life.

Abstract
BACKGROUND Gemcitabine (difluorodeoxycytidine) is active as a single agent in Hodgkin's disease and has been used successfully in combination with cisplatin to treat a variety of solid tumors. PATIENTS AND METHODS We evaluated the combination of gemcitabine/dexamethasone/cisplatin (GDP) as salvage chemotherapy in 23 patients with relapsed or refractory Hodgkin's disease (median age 36 years, range 19-57). Treatment consisted of gemcitabine 1000 mg/m(2) intravenously on days 1 and 8, dexamethasone 40 mg orally days 1-4 and cisplatin 75 mg/m(2) on day 1, every 21 days as an outpatient. Response was assessed following two cycles of treatment. RESULTS There were four complete responses and 12 partial responses for a response rate of 69.5% (95% confidence interval 52% to 87%); the remaining seven patients had stable disease and no patient progressed on treatment. All patients had successful stem cell mobilization and underwent transplantation with a median 10.6 x 10(6) CD34+ cells/kg. Hematological toxicity from GDP was mild (grade 3 neutropenia 8.6%, grade 3 thrombocytopenia 13%). CONCLUSIONS In summary, GDP is an active regimen for patients with relapsed or refractory Hodgkin's disease. The response rate is similar to the rates of other current salvage regimens, it can be given to outpatients with tolerable toxicity and it does not inhibit the mobilization of autologous stem cells.

Abstract
Pancreatic cancer remains a major unsolved health problem, with conventional cancer treatments having little impact on disease course. Almost all patients who have pancreatic cancer develop metastases and die. The main risk factors are smoking, age, and some genetic disorders, although the primary causes are poorly understood. Advances in molecular biology have, however, greatly improved understanding of the pathogenesis of pancreatic cancer. Many patients have mutations of the K-ras oncogene, and various tumour-suppressor genes are also inactivated. Growth factors also play an important part. However, disease prognosis is extremely poor. Around 15-20% of patients have resectable disease, but only around 20% of these survive to 5 years. For locally advanced, unresectable, and metastatic disease, treatment is palliative, although fluorouracil chemoradiation for locally advanced and gemcitabine chemotherapy for metastatic disease can provide palliative benefits. Despite pancreatic cancer's resistance to currently available treatments, new methods are being investigated. Preoperative chemoradiation is being advocated, with seemingly sound reasoning, and a wider role for gemcitabine is being explored. However, new therapeutic strategies based on the molecular biology of pancreatic cancer seem to hold the greatest promise.

Abstract
BACKGROUND For locally advanced and nonresectable cancer of the pancreas, we performed intra-arterial infusion chemotherapy with angiotensin-II (AT-II). In our preliminary report, this treatment resulted in a median of 14 months of survival without objective adverse effects. This study was designed to clarify the prognostic factor in this chemotherapy by using a larger number of cases. METHODS For 32 patients, intra-arterial chemotherapy was performed: 1 or 2 catheters were intraoperatively placed into the pancreas-supplying arteries. The tissue blood flow and its change by AT-II infusion were determined. For intra-arterial chemotherapy, a mixture of methotrexate (50 or 100 mg/m(2)) and AT-II (.4 microg/kg/hour) was repeatedly infused from the catheter, mainly at our outpatient clinic. RESULTS With our intra-arterial chemotherapy, the median survival period was 13 months. The median survival period was 19 months in patients without coexisting pancreatitis but was only 9 months in those with it (P =.0003). The presence or absence of coexisting fibrosis in the neighboring uninvolved pancreas offered the only prognostic indicator. The blood flow in cancerous tissue was increased during AT-II infusion, and this was characteristic in the patients whose neighboring uninvolved pancreas had normal parenchyma (nonatrophic) or higher blood flow before AT-II infusion. CONCLUSIONS Because the AT-II infusion played a role in shifting the blood flow from the surrounding uninvolved pancreas to the cancer tissues, we can speculate that cancer tissues might have thereby received a higher dose of anticancer drugs if the surrounding uninvolved pancreas had been nonfibrotic and more rich in tissue blood flow.

Abstract
Purpose The primary objective of this study was to determine the maximum-tolerated dose of cisplatin that could be added to full-dose gemcitabine and radiation therapy (RT) in patients with pancreatic cancer. Patients and Methods Nineteen patients were treated. Gemcitabine 1,000 mg/m2 was administered over 30 minutes on days 1, 8, and 15 of a 28-day cycle. Cisplatin followed gemcitabine on days 1 and 15. The initial dose level of cisplatin was 30 mg/m2, escalated to a targeted dose of 50 mg/m2 using Time-to-Event Continual Reassessment Method. RT was initiated on cycle 1, day 1, in 2.4 Gy fractions to a total dose of 36 Gy. A second cycle of chemotherapy was planned following a 1-week rest. Results Four of eight patients experienced acute dose limiting toxicity at the 50 mg/m2 cisplatin dose level. Patients treated at 30 and 40 mg/m2 cisplatin dose level tolerated therapy without dose-limiting toxicity. Median survival was 10.7 months (95% CI, 5.4 to 18.2) for all patients, and 12.9 months (95% CI, 7.4 to 21.2) for those without metastasis. Conclusion Cisplatin at doses up to 40 mg/m2 may be safely added to full-dose gemcitabine and conformal RT. The Time-to-Event Continual Reassessment Method trial design allowed rapid completion of the study and confidence in the conclusion about the maximum tolerated dose, but accrued more patients to a dose level above the maximum tolerated dose than the typical phase I design. Local and systemic disease control and survival in this study cohort supports further investigation of gemcitabine-based RT and combination chemotherapy in this disease.

Abstract
Pancreatic cancer is a common, highly lethal disease that is rising in incidence. Chemotherapy based on 5-fluorouracil (5-FU) has been shown to prolong survival in advanced pancreatic cancer. Gemcitabine improves major symptoms and survival outcomes compared with bolus 5-FU. Many novel small molecules are being widely and actively researched. These compounds are based on classical mechanisms of action as well as biological therapies targeting novel cellular survival pathways, and include fluoropyrimidines, nucleoside cytidine analogues, platinum analogues, topoisomerase-inhibitors, antimicrotubule agents, proteasome inhibitors, vitamin D analogues, arachidonic acid pathway inhibitors, histone deacytylator inhibitors, farnesyltransferase inhibitors and epidermal growth factor receptor therapies. Adjuvant chemotherapy has also demonstrated the best survival outcomes following resection compared to other adjuvant or neo-adjuvant strategies such as radiation-based treatments. These benefits are superimposed on the dramatic increase in resectability rates and reduction in post-operative mortality achieved by centralisation of treatment in high-volume speciality centres. Newer 'small-molecule' drugs as well as the latest 'large-molecule' biological agents hold considerable promise for the future. Real advances are anticipated over the next five years but are dependent on large randomised controlled trials for success.

Abstract
A small number of patients exist with carcinoma of the pancreas with an inoperable but not metastasized tumor. Prospective randomized studies defined the standard of combined radiochemotherapy during the early 1980s for these patients. Since then, new drugs have shown considerable activity and in parallel improvements in radiotherapy treatment planning and delivery have been achieved. Therefore, it is time to ask whether patients with locally advanced, inoperable pancreatic cancer without metastases should still be irradiated or not. This review summarizes the current literature on combined radiochemotherapy for locally advanced carcinoma of the pancreas. Median survival times of 10-11 months and 1-year survival rates of about 40% can be achieved with modern radiochemotherapy regimens.

Abstract
Pancreatic carcinoma is a commonly occurring cancer that tends to present late in its course when potentially curative surgical treatment is not possible. The majority of patients are, therefore, candidates for systemic therapy. We review the patient and disease-related factors that contribute to the difficulties in the medical management of this condition and discuss new methods of assessing response to treatment, including the introduction of more clinically relevant novel end points such as clinical benefit response. We review the current trial literature examining the use of conventional cytotoxic agents in this disease, both as single agents and in combination. We also review the use of more novel targeted agents and examine their potential utility in this disease. The use of the farnesyl transferase inhibitors, matrix metalloproteinase inhibitors, epidermal growth factor receptor antagonists, and angiogenesis inhibitors is discussed.

Abstract
PURPOSE To compare the selective matrix metalloproteinase inhibitor BAY 12-9566 with the nucleoside analog gemcitabine in the treatment of advanced pancreatic cancer. METHODS Patients with advanced pancreatic adenocarcinoma who had not previously received chemotherapy were randomly assigned to receive BAY 12-9566 800 mg orally bid continuously or gemcitabine 1,000 mg/m2 administered intravenously on days 1, 8, 15, 22, 29, 36, and 43 for the first 8 weeks, and then days 1, 8, and 15 of each subsequent 28-day cycle. The primary end point was overall survival; secondary end points were progression-free survival, tumor response, quality of life, and clinical benefit. The planned sample size of the study was 350 patients. Two formal interim analyses were planned. RESULTS The study was closed to accrual after the second interim analysis on the basis of the recommendation of the National Cancer Institute of Canada Clinical Trials Group Data Safety Monitoring Committee. There were 277 patients enrolled onto the study, 138 in the BAY 12-9566 arm and 139 in the gemcitabine arm. The rates of serious toxicity were low in both arms. The median survival for the BAY 12-9566 arm and the gemcitabine arm was 3.74 months and 6.59 months, respectively (P <.001; stratified log-rank test). The median progression-free survival for the BAY 12-9566 and gemcitabine arms was 1.68 and 3.5 months, respectively (P <.001). Quality-of-life analysis also favored gemcitabine. CONCLUSION Gemcitabine is significantly superior to BAY 12-9566 in advanced pancreatic cancer.

Abstract
Achieving substantial and meaningful improvements in the response and survival rates for advanced pancreatic cancer has proved to be an elusive goal for many years. 5-Fluorouracil (5-FU)-based chemotherapy has typically produced discouraging response rates or improved clinical benefit for patients, and attempts to improve these results by altering 5-FU dosages, administration schedules, or using a variety of drugs in combination with 5-FU have been unrewarding. A clinical benefit, however, was identified when gemcitabine first generated improvements in symptom control in patients with advanced disease. In a subsequent randomized trial, gemcitabine demonstrated superiority to 5-FU with respect to response rate, time to progression, and median survival. These improvements were also associated with improvement in clinical benefit. The findings of subsequent randomized Phase III trials have suggested a survival benefit for gemcitabine compared with several single agents or combinations. Gemcitabine has thus become the de facto standard of care for advanced pancreatic cancer, and current efforts are directed toward finding strategies that can capitalize on and extend these clinical benefits.

Abstract
PURPOSE This phase II study was undertaken to determine the efficacy of adding infusional fluorouracil (FU) to the chemotherapy doublet of gemcitabine and cisplatin in patients with advanced pancreatic cancer. PATIENTS AND METHODS The eligibility criteria included histologically or cytologically confirmed adenocarcinoma of the pancreas that was either unresectable or metastatic. No prior gemcitabine therapy was allowed. Patients received a combination of gemcitabine 1000 mg/m2 intravenously (IV) on days 1, 8, and 15; cisplatin 50 mg/m2 IV on days 1 and 15; and FU 175 mg/m2/d from days 1 to 15 by continuous IV infusion. Cycles were repeated every 28 days. Objective tumor response and toxicity were evaluated according to the World Health Organization criteria. RESULTS A total of 47 patients (median age, 57 years; males, 59%) were enrolled. Sixteen patients had locally advanced (LA) disease, and 31 patients had metastatic disease. A total of 183 cycles of chemotherapy were administered. In patients with metastatic disease (n = 31), the probability of survival at 6 and 12 months was 66% and 34%, respectively. Objective partial response or stable disease was observed in 26% (90% confidence interval [CI], 0.14 to 0.41) and 61% (90% CI, 0.45 to 0.74) of patients, respectively. In patients with LA disease (n = 16), there were three partial responses (19%; 90 CI, 0.07 to 0.39). One patient in this group was successfully resected after FU-based radiotherapy. The most common grade 3 to 4 toxicities were neutropenia (60%), thrombocytopenia (42%), and anemia (26%). Thirteen patients were hospitalized for treatment-related complications. CONCLUSION The combination of gemcitabine, cisplatin, and infusional FU has significant activity in patients with advanced pancreatic cancer.

Abstract
OBJECTIVE Recurrent and advanced cervical cancers are associated with high mortality and a lack of effective treatment options, especially for women who are poor candidates for surgery or radiation therapy. The broad clinical effectiveness and low toxicity of gemcitabine in other human malignancies suggest that it might be useful in treating cervical tumors. METHODS Fifteen phase I/II clinical trials on the use of gemcitabine, both as a single agent and in combination with cisplatin, in patients with recurrent or advanced carcinoma of the cervix were reviewed. Data from studies in which gemcitabine was used in combination with radiotherapy for induction therapy and with cisplatin for neoadjuvant chemotherapy were also evaluated. RESULTS Although single-agent gemcitabine was generally inferior to cisplatin, when used concurrently with cisplatin and/or radiation therapy, objective response rates were high and survival was prolonged. The drug also showed promise when used with cisplatin as neoadjuvant therapy. CONCLUSIONS Initial studies suggest that gemcitabine may be useful in the management of recurrent or advanced cervical cancer when used concurrently with cisplatin. Accordingly, a large phase III study will compare cisplatin/gemcitabine with the current standard, and further evaluation of gemcitabine appears to be warranted in conjunction with radiotherapy and in the neoadjuvant setting.

Abstract
BACKGROUND The effective treatment of unresectable pancreatic carcinoma represents a formidable challenge. There is a need to develop systemic therapies which combine efficacy with acceptable toxicity. The current 'gold standard' gemcitabine gives an objective response rate of the order of 20% and median survival up to 6 months. Here we have evaluated the efficacy and toxicity of mitomycin C, cisplatin and protracted infusional 5-fluorouracil (MCF). PATIENTS AND METHODS Forty-five patients with locally advanced (13 patients) or metastatic (32 patients) pancreatic carcinoma were treated with mitomycin C 7 mg/m(2) 6 weekly, cisplatin 60 mg/m(2) 3 weekly and protracted venous infusion 5-FU 300 mg/m(2)/day. Patients were evaluated for response after three cycles and received six cycles in total in the absence of progressive disease or poor tolerance. Median age was 62 (45-75) years; 41 patients were World Health Organization performance status 0-1. RESULTS Treatment was well tolerated with 36 (84%) patients completing three or more cycles. Grade 3 or 4 toxicities were uncommon: anaemia in three patients (7%), mucositis in two (5%), nausea and vomiting in three (7%) and diarrhoea in one (1%). An objective response was seen in 21 (46%) patients. There was one complete response. The median survival overall was 7.1 months and 10.5 months in responders. The median duration of response was 4.3 months. One-year survival was 29%, 2-year survival was 18%. CONCLUSIONS MCF combines efficacy with low toxicity in the treatment of advanced pancreatic carcinoma. The efficacy is at least comparable and may be superior to single-agent gemcitabine and MCF may therefore provide a cost-effective alternative.

Abstract
This update is devoted to discussion of optimal supportive and palliative care of patients with pancreatic cancer. Approximately 33,000 new cases of pancreatic cancer are predicted for the U.S. in 2002. Because diagnosis and intervention occur late in the course of this disease, the vast majority of patients already have metastatic disease at the time of diagnosis. These tumors are relatively resistant to systemic chemotherapy, making pancreatic cancer the fourth leading cause of cancer-related death in the U.S. and the Western world. For these reasons, efforts at identifying and treating disease-related symptomatology are priorities. This update overviews symptom management, supportive care strategies, and both standard and emerging palliative chemotherapy options. The incorporation of molecularly targeted therapies into treatment of metastatic pancreatic cancer is reviewed as well. These strategies are of relevance to internists, gastroenterologists, oncologists, and other specialists who care for patients with pancreatic cancer.

Abstract
Advances in chemotherapy for pancreatic cancer have been limited. In the past decade, the standard therapy for metastatic disease has switched from 5-fluorouracil (5-FU) to gemcitabine. However, several other cytotoxic agents have shown limited but promising efficacy in pancreatic cancer, and many of these appear to be well suited for combination chemotherapy. Although 5-FU and cisplatin have not demonstrated substantial survival benefits when combined with gemcitabine, results of several phase III trials with other agents are still pending. For locally advanced disease, most recent studies have incorporated gemcitabine into combined-modality therapy. Similarly, in surgically resectable disease, current trials are incorporating gemcitabine into adjuvant therapy. Other trials are using neoadjuvant therapy as a possible means to improve upon current surgical results. However, much hope comes from the development of newer "targeted" therapies for this disease. Although matrix metalloproteinase inhibitors and farnesyl transferase inhibitors did not appear to be effective in initial studies, other targeted therapies are beginning to enter clinical trials.

Abstract
The results from pancreatic ductal adenocarcinoma appear to be improving with increased resection rates and reduced postoperative mortality reported by specialist pancreatic cancer teams. Developments with medical oncological treatments have been difficult, however, due to the fundamentally aggressive biological nature of pancreatic cancer and its resistance to chemotherapy coupled with a relative dearth of randomised controlled trials. The European Study Group for Pancreatic Cancer (ESPAC)-1 trial recruited nearly 600 patients and is the largest trial in pancreatic cancer. The results demonstrated that the current best adjuvant treatment is chemotherapy using bolus 5-fluorouracil with folinic acid. The median survival of patients randomly assigned to chemoradiotherapy was 15.5 months and is comparable with many other studies, but the median survival in the chemotherapy arm was 19.7 months and is as good or superior to multimodality treatments including intra-operative radiotherapy, adjuvant chemoradiotherapy and neo-adjuvant therapies. The use of adjuvant 5-fluorouracil with folinic acid may be supplanted by gemcitabine but requires confirmation by ongoing clinical trials, notably ESPAC-3, which plans to recruit 990 patients from Europe, Canada and Australasia. Major trials such as ESPAC-1 and ESPAC-3 have set new standards for the development of adjuvant treatment and it is now clear that such treatment in this field has the potential to significantly improve both patient survival and quality of life after curative resection.

Abstract
BACKGROUND Gemcitabine has evolved as standard therapy in advanced pancreatic cancer since the demonstration of a significant clinical benefit. Phase II trials have shown that gemcitabine can be successfully combined with thymidylate synthase (TS) inhibitors such as continuous-infusion 5-fluorouracil (5-FU). However, continuous-infusion 5-FU is inconvenient because of the need for a central venous access. The aim of this study was to assess the efficacy and safety of gemcitabine in combination with raltitrexed (Tomudex), a novel and selective TS inhibitor that has the advantage of a 3-weekly treatment interval and manageable toxicity. PATIENTS AND METHODS Chemotherapy-naïve patients with measurable advanced pancreatic cancer were treated with raltitrexed 3 mg/m(2) as a 15-min infusion on day 1 and gemcitabine 1000 mg/m(2) on days 1 and 8, every 21 days. RESULTS Twenty-five eligible patients (17 male, eight female) with metastatic (21 patients) or locally advanced (four patients) disease entered the study. The median number of courses per patient was four (range 1-14). One patient was not evaluable for response. There were three partial remissions [12%; 95% confidence interval (CI) 2.6% to 31.2%] and nine stable disease situations (36%; 95% CI 18.0% to 57.5%), while the tumours of 12 patients (48%; 95% CI 27.8% to 68.7%) showed progressive disease after three treatment cycles. WHO grade 3/4 toxicity was rare and symptomatic in only one patient, who experienced grade 4 diarrhoea and grade 3 nausea and vomiting. Symptomatic benefit was seen in 12 patients. Median survival was 185 days (95% CI 129-241) with six patients still alive. CONCLUSIONS The efficacy of raltitrexed plus gemcitabine is limited, but compares well with other chemotherapy treatment options in advanced pancreatic cancer. However, this combination is convenient and symptomatic toxicity is rare. Thus, raltitrexed and gemcitabine should be investigated further in combination with drugs interfering with specific molecular targets.

Abstract
BACKGROUND This phase II study was initiated to determine the activity and toxicity of a combination of gemcitabine (GEM) and cisplatin (CDDP) in patients with pancreatic cancer. PATIENTS AND METHODS CDDP 35 mg/m(2) was given as a 30-min infusion and GEM 1000 mg/m(2) as a 30-min infusion. Both drugs were administered once weekly for 2 consecutive weeks out of every 3 weeks to chemonaive patients with locally advanced or metastatic pancreatic cancer. RESULTS Forty-five advanced pancreatic cancer patients received this regimen for a total of 180 cycles of chemotherapy. One complete and four partial responses have been observed for an overall response rate of 9% (95% confidence interval 10% to 11%). Twenty-one patients (46%) had stable disease and 19 progressed on therapy. The median time to progression was 3.6 months, with a median survival of 5.6 months. A clinical benefit was obtained in nine of 37 patients (24%). Side-effects were mainly represented by hematological toxicity. Grade 3/4 WHO toxicities included neutropenia (6% of the patients) and thrombocytopenia (11%). The dose of GEM and CDDP was reduced in 14 patients (31%) and treatment was delayed in 10 patients (22%). CONCLUSIONS Our results in terms of response rate, clinical benefit and survival do not support an advantage for the combination of GEM and CDDP given by this schedule.

Abstract
Metastatic pancreatic cancer is one of the leading causes of cancer-related deaths in North America and Europe. In the past, patients with metastatic pancreatic cancer have had few treatment options. However, recently, several effective palliative therapies and procedures have become available. The systemic administration of gemcitabine has been shown to result in clinical benefit and in a prolongation of median survival, and is now established as the standard first-line treatment for patients with metastatic pancreatic cancer. Clinical trials are exploring whether the use of gemcitabine-based chemotherapy combinations will result in further benefit. Several novel chemotherapeutic and biologic agents appear promising, and are likely to play a role in the treatment of patients with pancreatic cancer in the future. Palliative procedures, such as biliary or duodenal stenting and celiac plexus blockade, should be considered in conjunction with systemic therapy in patients with specific complications from pancreatic cancer.

Abstract
Death from pancreatic cancer remains high with few long-term survivors. Systemic chemotherapy with 5-fluorouracil-based combinations had minimal impact on natural history of this disease. Several new agents with activity against pancreatic cancer have been identified over the past decade. Gemcitabine has modest activity in this disease. Combination chemotherapy trials incorporating gemcitabine, cisplatin, 5-fluorouracil, oxaliplatin, docetaxel or irinotecan show improved outcomes in objective response rates and survival that need to be confirmed in prospectively randomized studies. Advancement in the understanding of the biology of pancreatic cancer has helped identify several molecular targets for the development of novel therapies. Ongoing and future treatment regimens for pancreatic cancer will incorporate traditional cytotoxic drugs and novel targeted therapies.

Abstract
Until recently, 5-fluorouracil was the most widely used treatment for non-resectable pancreatic cancer. This treatment, however, only resulted in a median survival time of approximately 4 months. In the last few years, gemcitabine has rapidly become the new treatment benchmark, due more to its superior clinical benefit rather than to it conferring an increased median survival (approximately 5-6 months). Thus, the outlook for patients with pancreatic cancer is still relatively bleak. A number of new treatment options are presently being investigated. Some of these are combination therapies involving gemcitabine and other chemotherapeutic agents or radiation. Other novel treatment strategies are also already being evaluated in clinical studies. Some of the more promising treatments in development are discussed and evaluated in this article.

Abstract
Gemcitabine has become a new standard for treatment of advanced pancreatic cancer. This development is based not only on drug efficacy but also on a favorable side-effect profile. Combinations of gemcitabine with antitumor drugs such as cisplatin, 5-fluorouracil, docetaxel, irinotecan, oxaliplatin, or capecitabine, and biological agents such as cetuximab or trastuzumab, have yielded promising results in phase II trials. However, none of these combinations has yet reached the level of an evidence-based standard treatment.
