Abstract
Aims and background In recent years, preoperative chemoradiation has received growing interest for the treatment of locally advanced pancreatic cancer. In an attempt to improve resectability and disease control, we used preoperative radiation therapy and concomitant 5-fluorouracil in a combined modality therapy protocol. The aim of the study was to evaluate definitive results in terms of toxicity, response and clinical outcome. Material and methods Twenty-eight patients with unresectable (cT4,19 patients) or resectable (cT3, 9 patients) nonmetastatic pancreatic tumors received radiotherapy (39.6 Gy) plus 5-fluorouracil (continuous infusion, days 1-4 at 1000 mg/m2/day). After 4 weeks, patients were evaluated for surgical resection. In 9 resected patients, electron-beam intra-operative radiotherapy (10 Gy) was given before reconstruction. Thereafter, in resected patients, adjuvant chemotherapy was prescribed. Results During chemoradiation, 1 patient (3.6%) developed grade 3 acute gastrointestinal toxicity and 2 patients (7.1%) developed grade 3 hematological toxicity. Three of 19 patients with unresectable tumors had tumor downstaging (15.8%). Two patients showed partial response (response rate, 7.1%; 95% CI, 0.2-25.3) and 4 patients (14.3%) had minimal tumor response. Four patients (14.3%) showed progressive disease after chemoradiation. One postoperative death was recorded. The median survival time was 11.3 months (20.5 and 9.0 months in resected and unresected patients, respectively). Only one local failure was recorded in 8 patients resected with negative margins. Conclusions Although the response rate is still low, our preliminary results suggest that preoperative 5-fluorouracil chemoradiation is well tolerated and may result in tumor downstaging. Delivery of intra-operative radiotherapy seems to be associated with a low rate of local recurrences.

Abstract
The delivery of postoperative combined modality adjuvant therapy for completely resected pancreatic adenocarcinoma was initially shown to be beneficial based on a prospective, randomized trial published 30 years ago. Since then, oncologists have debated whether chemotherapy alone, chemoradiation, or both are optimal adjuvant therapies following pancreatectomy for pancreatic ductal adenocarcinomas (PDAC). No global consensus has emerged, and there is no one superior modality despite randomized trials in part, to poor trial design, poor patient selection, and poor therapy options itself. We need to have a disciplined approach to the selection of patients for pancreatectomy, pathologic assessment of surgical resection margins, and postoperative (pre-treatment) imaging. In the era of the multidetector CT optimized for pancreatic imaging, tumors of "borderline resectability" have emerged as a distinct subset of PDAC. The attempt to standardize the definition of borderline resectable is a work in progress and modified with time. This distinction (between resectable and borderline resectable) is essential to minimize potentially confounding results of clinical trials. Additionally, preoperative therapy is not only preferred but mandatory in a large population of borderline resectable patients. Ultimately, as we develop more effective systemic therapies for PDAC, proceeding with surgery after a period of induction therapy will be even more compelling especially if there is a clear positive impact on overall survival.

Abstract
The role of neoadjuvant chemoradiation therapy in locally advanced pancreatic cancer (LAPC) is still controversial. The aim of this study was to evaluate surgical downstaging after concurrent chemoradiation therapy (CCRT) for LAPC by measuring the objective changes after treatment. From January 2003 through July 2011, 54 patients with LAPC underwent neoadjuvant CCRT. Computed tomography findings of the tumor size, including major vessel invasion, were analyzed before and after CCRT. Among the total recruited patients, 14 had borderline resectable malignancy and another 40 were unresectable before CCRT. After CCRT, a partial response was achieved in four patients. Stable disease and further disease progression were achieved in 36 and 14 patients, respectively. Tumor size showed no significant difference before and after CCRT (3.6 ± 1.1 vs. 3.6 ± 1.0 cm, P = 0.61). Vessel invasion showed improvement in two patients, while 13 other patients showed further tumor progression. Thirty-nine patients with unresectable malignancy and 11 patients with borderline resectable malignancy at time of initial diagnosis remained unchanged after CCRT. Four patients with borderline pancreatic malignancy progressed to an unresectable stage, whereas one unresectable pancreatic malignancy improved to a borderline resectable stage. Only one patient with borderline resectable disease underwent operation after CCRT; however, curative resection failed due to celiac artery invasion and peritoneal seeding. The adverse events associated with CCRT were tolerable. In conclusion, preoperative CCRT in LAPC rarely leads to surgical downstaging, and it could lower resectability rates.

Abstract
Pancreatic adenocarcinoma remains the fourth leading cause of cancer mortality in the U.S. Despite advances in surgical technique, radiotherapy technologies, and chemotherapeutics, the 5-year survival rate remains approximately 20% for the 15% of patients who are eligible for surgical resection. The majority of this group suffers metastatic recurrence. However, despite advances in therapies for patients with advanced pancreatic cancer, only surgery has consistently proven to improve long-term survival. Various combinations of chemotherapy, biologic-targeted therapy, and radiotherapy have been evaluated in different settings to improve outcomes. In this context, a neoadjuvant (preoperative) treatment strategy offers numerous potential benefits: (1) ensuring delivery of early, systemic therapy, (2) improving selection of patients for surgical therapy with truly localized disease, (3) potential downstaging of the neoplasm facilitating a negative margin resection in patients with locally advanced disease, and (4) providing a superior clinical trial mechanism capable of rapid assessment of the efficacy of novel therapeutics. This article reviews the recent trends in the management of pancreatic adenocarcinoma, with a particular emphasis on a multidisciplinary neoadjuvant approach to treatment.

Abstract
Treatment of pancreatic cancer is increasingly multimodal, with patients receiving chemotherapy, radiation, and surgical extirpation in hope of long-term cure. There is ongoing debate over the timing, sequence, and necessity of these treatments as they pertain to the spectrum of local-regional disease. Current guidelines support a neoadjuvant strategy in patients with locally advanced and borderline resectable disease. Although there is currently no high-level evidence to recommend neoadjuvant therapy for all patients, there are data to suggest that wider application of neoadjuvant therapy may be beneficial. Random-assignment prospective trials are ongoing. In this review we examine the literature addressing a neoadjuvant approach to potentially resectable, borderline resectable, and locally advanced pancreatic cancer and highlight the outcomes of preoperative emergence of latent metastatic disease, attempted resection rates, margin negative resection rates, and pathologic response to treatment.

Abstract
BACKGROUND The purpose of this study was to evaluate whether (18)F-fluorodeoxyglucose positron emission tomography in combination with computed tomography (FDG-PET/CT) could correctly predict the pathologic response to preoperative chemoradiation therapy (CRT) for resectable pancreatic cancer. METHODS Each of the 40 patients underwent FDG-PET/CT before and after preoperative CRT. The maximum standard uptake value (SUV) was measured for the primary tumor before and after preoperative CRT, defined as pre-CRT SUV and post-CRT SUV, respectively. The proportional alteration of the SUV decline (regression index) between post-CRT SUV and pre-CRT SUV was also calculated. These three indicators were associated with the pathologic response. RESULTS Patients were classified as 21 responders and 19 nonresponders according to the histologic features. A pre-CRT SUV ≥ 4.7 was seen in 15 (71 %) of 21 responders and in 6 (32 %) of 19 nonresponders (p = 0.03). A regression index ≥ 0.46 was seen in 15 (71 %) responders and 5 (26 %) nonresponders (p = 0.01). CONCLUSIONS A better pathological response can be expected for pancreatic cancer patients who have a high regression index (≥ 0.46) and a high pre-CRT SUV (≥ 4.7). The SUV measurement using FDG-PET/CT is a useful tool for predicting the pathologic response to preoperative CRT.

Abstract
Conflicting data and substantial controversy exist regarding optimal adjuvant treatment for those patients with resectable or potentially resectable adenocarcinoma of the pancreas. Despite improvements in short-term surgical outcomes, the use of newer chemotherapeutic agents, development of targeted agents and more precise delivery of radiation, the 5-year survival rates for early-stage patients remains less than 25%. This article critically reviews the existing data for various adjuvant treatment approaches for patients with surgically resectable pancreatic cancer. Our review confirms that despite several randomized clinical trials, the optimal adjuvant treatment approach for these patients remains unclear.

Abstract
AIM To analyze the results of extracranial stereotactic radiotherapy (ESRT) experience in pancreatic cancer patients. METHODS Four noncoplanar fixed beams were used in all patients. RESULTS Analysis of 16 patients was carried out. Overall response rate was 56.2%. Fifteen patients experienced local and/or distant progression of disease (median follow-up: 24 months). Two-year local progression-free, distant progression-free, and overall survivals were 85.7%, 58.7%, and 50.0%, respectively. Toxicity was less than grade 2 in all, although 1 patient had severe duodenal bleeding. Quality of life scores were unchanged. CONCLUSIONS ESRT was associated with low complication rate, and not worsening the patients' quality of life.

Abstract
Pancreatic cancer is a devastating disease. It is the fourth leading cause of cancer-related death in Germany. The incidence in 2003/2004 was 16 cases per 100.000 inhabitants. Of all carcinomas, pancreatic cancer has the highest mortality rate, with one- and five-year survival rates of 25% and less than 5%, respectively, regardless of the stage at diagnosis. These low survival rates demonstrate the poor prognosis of this carcinoma. Previous therapeutic approaches including surgical resection combined with adjuvant therapy or palliative chemoradiation have not achieved satisfactory results with respect to overall survival. Therefore, it is necessary to evaluate new therapeutic approaches. Neoadjuvant therapy is an interesting therapeutic option for patients with pancreatic cancer. For selected patients with borderline or unresectable disease, neoadjuvant therapy offers the potential for tumor downstaging, increasing the probability of a margin-negative resection and decreasing the occurrence of lymph node metastasis. Currently, there is no universally accepted approach for treating patients with pancreatic cancer in the neoadjuvant setting. In this review, the most common neoadjuvant strategies will be described, compared and discussed.

Abstract
Pancreatic adenocarcinoma carries a dismal prognosis and remains a significant cause of cancer morbidity and mortality. Most patients survive less than 1 year; chemotherapeutic options prolong life minimally. The best chance for long-term survival is complete resection, which offers a 3-year survival of only 15%. Most patients who do undergo resection will go on to die of their disease. Research in chemotherapy for metastatic disease has made only modest progress and the standard of care remains the purine analog gemcitabine. For resectable pancreatic cancer, presumed micrometastases provide the rationale for adjuvant chemotherapy and chemoradiation (CRT) to supplement surgical management. Numerous randomized control trials, none definitive, of adjuvant chemotherapy and CRT have been conducted and are summarized in this review, along with recent developments in how unresectable disease can be subcategorized according to the potential for eventual curative resection. This review will also emphasize palliative care and discuss some avenues of research that show early promise.

Abstract
Adjuvant therapy for pancreatic cancer remains a controversial topic, with a paucity of randomized controlled trials in this area and various limitations in the trials that have been conducted to date, leaving many questions as to a true "standard of care" for patients with resectable or potentially resectable disease. Several large and well-conducted phase 3 trials have reported results recently and have helped to solidify the role of chemotherapy, with either 5-fluorouracil or gemcitabine, as an effective intervention in the adjuvant setting. The role of radiotherapy remains unclear, but it does seem to be feasible and safe, and there are trials in development that may shed more light on this question. Many small trials have pointed to the potential utility of neoadjuvant strategies in selecting the patients who are most likely to benefit from surgery and in improving outcomes by providing systemic therapy early on. Larger trials are ongoing in hopes that they will give more definitive answers as to when this strategy should be used. It is hoped that trials using novel agents, either alone or in combination with more traditional therapies, will better define the best strategy for improving outcomes in patients with resectable disease.

Abstract
PURPOSE This study suggests that pancreatic adenocarcinoma is a chemoradiosensitive tumor and that preoperative chemoradiation provides antitumoral effect associated with major histopathological response in 50% of patients and a high R0 resection rate. Evaluation of histopathological response to neoadjuvant therapy may serve as a surrogate marker for treatment efficacy and remains an active area of investigation. OBJECTIVES The chemoradiosensitive of pancreatic adenocarcinoma has not yet fully been assessed. The purpose of this study is to determine the efficacy of preoperative chemoradiation, measured by the impact on the R0 resection rate and the histopathological response rate in patients presenting with resectable pancreatic adenocarcinoma. METHODS Patients with localized, potentially resectable pancreatic adenocarcinoma were treated with 50 Gy irradiation combined with 5-fluorouracil by continuous infusion (300 mg . m(-2) . d(-1); day 1-5; week 1-5) and cisplatin (20 mg . m(-2) . d(-1); day 1-5 and day 29-33). Patients presenting with resectable disease at restaging, without metastatic dissemination, underwent surgical resection. RESULTS Forty-one patients were enrolled. Twenty-seven patients (67.5%) completed chemoradiation receiving at least 75% prescribed chemotherapy dose without grade 4 nonhematological toxicity. Twenty-six patients (63%) underwent surgical resection with curative intent and 21 (80.7%) had R0 resection. Thirteen of 26 specimens (50%) presented a major pathologic response with more than 80% of severely degenerative cancer cells. Complete pathologic response was observed in one specimen. Median survival time and 2-year survival rate were 9.4 months and 20% for the entire cohort. The local recurrence and 2-year survival rates were 4% and 32%, respectively, for the 26 operated patients. CONCLUSIONS This study suggests that some pancreatic adenocarcinomas are chemoradiosensitive and that preoperative chemoradiation provides antitumoral effect associated with major histopathological response in 50% of patients and a high R0 resection rate. Further research is needed to determine the biologic difference between responders and nonresponders, to evaluate the predictive value of treatment response parameters, and to optimize the chemoradiation regimen.

Abstract
Surgical resection is necessary but generally insufficient as curative treatment for pancreatic cancer. Traditionally, postoperative (adjuvant) therapies have been utilized in an attempt to improve outcome, yet these efforts have met with extremely limited success. As preoperative (neoadjuvant) treatment strategies have evolved for the treatment of other malignancies, preoperative therapy for pancreatic cancer has been investigated by several groups over the past decade. At this time, no randomized trials comparing adjuvant and neoadjuvant therapies have been performed, nor have there been any large multicenter trials of neoadjuvant therapy for pancreatic cancer. In this manuscript, the rationale for neoadjuvant strategies are discussed in the context of the available data on both adjuvant and neoadjuvant therapy and clinical trials currently in development.

BACKGROUND We evaluated the feasibility and efficacy of neoadjuvant chemotherapy and radiation for patients with locally unresectable pancreatic cancer. MATERIALS AND METHODS From October 2000 to August 2006, 245 patients with pancreatic adenocarcinoma underwent surgical exploration at our institution. Of these, 78 patients (32%) had undergone neoadjuvant therapy for initially unresectable disease, whereas the remaining patients (serving as the control group) were explored at presentation (n=167). All neoadjuvant patients received gemcitabine-based chemotherapy, often in conjunction with docetaxal and capecitabine in a regimen called GTX (81%). Seventy-five percent of neoadjuvant patients also received preoperative abdominal radiation (5,040 rad). RESULTS Neoadjuvant patients were younger than control-group patients (60.8 vs 66.2 years, respectively, p<0.002). Seventy-six percent of neoadjuvant patients were resected as compared to 83% of control patients (NS). Concomitant vascular resection was required in 76% of neoadjuvant patients but only 20% of NS (p<0.01). Complications were more frequent in the neoadjuvant group (44.1 vs 30.9%, p<0.05), and mortality was higher (10.2 vs 2.9%, p<0.03). Among the neoadjuvant patients, all but one of the deaths were in patients that underwent arterial reconstruction. Mortality for patients undergoing a standard pancreatectomy without vascular resection was 0.8% in this series. Of patients resected, negative margins were achieved in 84.7% of neoadjuvant patients and 72.7% of NS. Within the cohort of neoadjuvant patients, radiation significantly increased the complication rate (13.3 vs 54.6%, p<0.006), but did not affect median survival (512 vs 729 days, NS). Median survival for patients who received neoadjuvant therapy (503 days) was longer than NS that were found to be unresectable at surgery (192 days, p<0.001) and equivalent to NS that were resected (498 days). CONCLUSIONS Resection rate, margin status, and median survivals were equivalent when neoadjuvant patients were compared to patients considered resectable by traditional criteria, demonstrating equal efficacy. Surgical resection with venous reconstruction following neoadjuvant therapy for patients with locally advanced pancreatic cancer can be performed with acceptable morbidity and mortality. This approach extended the boundaries of surgical resection and greatly increased median survival for the "inoperable" patient with advanced pancreatic cancer.

Abstract
Ductal adenocarcinoma of the pancreas is one of the leading causes of cancer death in the UK, Europe and US, with incidence closely paralleling mortality. Until recently, enthusiasm for treating these patients was limited for a number of reasons: the majority of patients undergoing surgery would relapse early, adjuvant treatment was of unproven value and systemic therapy in advanced disease had only a small chance of a short-term benefit. More recently, however, it has become recognised that specialist surgery can improve results and there is evidence that adjuvant chemotherapy has a significant advantage in terms of 5-year survival. In particular adjuvant systemic 5-fluorouracil with folinic acid can result in 5-year survival of < or = 29% (compared with 11% for controls) and adjuvant gemcitabine can improve disease-free survival to 13.4 months from a median of 6.9 months in controls, but not overall survival. In contrast the role of adjuvant chemoradiation in addition to chemotherapy remains unproven and the survival results appear to be inferior to systemic chemotherapy alone. New agents, such as capecitabine and erlotinib, are emerging with some activity in this dismal disease signalling hope for the future.

Abstract
Pancreatic cancer is the fourth leading cause of cancer-related death in the USA. The disease has a high mortality rate and the 5-year survival rate is estimated to be 4%. Currently, surgical resection is only possible in 20% of patients; even then, the overall 5-year survival rate is only 25%. As such, surgical therapy alone is not sufficient for pancreatic carcinoma, and prospective investigation of additional modalities is crucial. Numerous negative trials have shown that chemotherapy alone is the standard of care after resection of pancreatic carcinoma. However, results remain poor and progress with new drugs is needed in this setting. For locally advanced disease, the situation is more complicated; the ideal chemoradiation schedule has not been clearly defined, and improvements could come in the near future from the use of new radiotherapy tools and targeted therapies. For advanced disease, chemotherapy alone has given very disappointing results. A multidisciplinary approach combining biological assessment of targets with clinical trials to evaluate new targeted drugs should be considered.

Abstract
Median as well as overall survival of pancreatic cancer patients in the advanced stage is extremely low despite advances in cancer therapy regarding tumor cell biology, therapy resistance, and diagnosis. In matters of chemoradiation therapy (CRT) in locally advanced pancreatic cancer, favorable positive effect has been reached with different radiotherapy proceedings such as intraoperative radiation therapy with or without external chemo-/radiation therapy or with CRT alone with regard to local tumor pain, local tumor remission, or local control of disease and overall survival. Primary (chemo-) radiation therapy only rarely leads to local remission. Intraoperative radiation therapy (IORT) merely reaches pain palliation in most cases. By administering up-to-date primary CRT, especially with gemcitabine-associated CRT, local remission in up to 50% of patients can be observed. By applying neoadjuvant CRT, better resectability and the reduction of postoperative positive lymph node metastasis has been seen in patients with resectable or possibly resectable pancreatic cancer. With primary CRT, resectability can also be achieved in patients with primary unresectable pancreatic cancer. It has been shown at the evaluation of patients' progression samples--either treated with neoadjuvant or primarily with radiotherapy (with conventional radiation technique)--that the rate of local recurrence or local progression can be reduced in comparison with historical cohorts. By contrast, the rate on distant metastases was not affected. Whereas concurrent CRT leads to favorable local tumor control, this procedure has a minor effect as to the survival in most of the studies. Because metastases occur mostly out of the irradiation field and because of partly advanced local tumor progression, the concept of combined CRT with continuing chemotherapy was developed. Median survival of pancreatic patients in the advanced stage is approx. 3-5 months, with a 12-month survival probability of 10% despite advances in cancer therapy. On the other hand, the 5-year survival probability is 0.4%-3.0%. The causes of such a dismal prognosis can be understood first of all in the commonly late diagnosis, second in the aggressive tumor cell biology with continuing therapy resistance, and finally because an acceptable resection rate can be achieved only in specialized centers. Only 10%-15% of patients can be resected after the diagnosis of pancreatic cancer. Resection is considered a potential curative therapy. However, median survival of these patients amounts to only 13-18 months, with a 5-year survival of 10%-20%. The survival rate did not improve with a radical resection and extended lymphadenectomy. Furthermore, 15%-30% of primary nonmetastatic pancreatic cancer is unresectable due to extended vessel infiltration at time of diagnosis. The prognosis for these patients is very dismal due to lack of specific therapy; moreover, median overall survival is a maximum of 6-8 months.

Abstract
PURPOSE To test the hypothesis that dual biochemical modulation of fluorouracil (FU) in combination with mitomycin improves the survival of patients with pancreas cancer. PATIENTS AND METHODS Eligibility included stage II or III unresectable adenocarcinoma of the pancreas, performance status of 0 to 2, and adequate organ function. Treatment included FU 200 mg/m2/d via continuous intravenous infusion for 4 weeks followed by 1 week of rest; leucovorin 30 mg/m2 administered via intravenous bolus infusion on days 1, 8, 15, and 22, followed by 1 week rest; mitomycin 10 mg/m2 intravenous bolus infusion every 6 weeks for a total of four doses. Dipyridamole 75 mg was administered orally three times daily during the FU administration. RESULTS Fifty patients (median age, 61 years; 23 males, 27 females) with localized unresectable pancreatic cancer were eligible for this trial. Twenty-seven patients survived past 1 year for a 1-year survival probability of 54% (95% CI, 40% to 68%). Overall, the objective response rate was 26% (confirmed and unconfirmed) in the 47 patients with measurable disease, with two complete responders. Six of the responding patients underwent curative successful resection of the tumor. The most common toxicity to treatment was stomatitis. Three patients had reversible hemolytic uremic syndrome. Five patients experienced grade 4 toxicity. There were no treatment-related deaths. CONCLUSION Potential improvement in survival and resectability of localized unresectable pancreatic cancer may be attained without radiation. The strategy of dual biochemical modulation of FU warrants additional investigation in a randomized fashion.

Abstract
Although complete surgical resection, when possible, leads to prolonged survival in pancreatic cancer, if used alone, its results remain sub-optimal. Neoadjuvant strategies are recent in pancreatic cancer: in primary resectable tumors, they ensure that all patients obtain additional treatment to complete surgery; in locally advanced tumors, they allow a better selection of candidates for curative resection. By delaying surgery, neoadjuvant strategies modify the initial diagnostic process and the symptomatic treatment of pancreatic cancer. Several recent phase I-II studies have confirmed the feasibility and efficacy of the association of chemotherapy and radiotherapy, which is well-tolerated and is associated with better local control and survival. Due to the aggressiveness of pancreatic cancers, most recent cytotoxic agents should be associated with modern radiation techniques. Neoadjuvant chemoradiation is under evaluation in pancreatic cancers, and no randomized phase III trials comparing neoadjuvant and adjuvant therapeutic sequences has been reported. Moreover, radiological and pathological evaluations, not only at diagnosis, but also after preoperative chemoradiation, must be standardized to improve the selection of patients who will benefit from this multi-modal treatment.

Abstract
BACKGROUND The most accepted treatment for locally advanced pancreatic cancer is chemoradiotherapy. However, indications to and results of pancreatic resections after chemoradiation are not yet defined. METHODS From June 1999 to December 2003, 28 patients with locally advanced pancreatic cancer (group 1) were enrolled for institutional trials of gemcitabine-based chemoradiotherapy. Tumors were stratified as unresectable or borderline resectable according to the pattern of vascular involvement at pretreatment computed tomographic scan. Patients with partial response or stable disease and in-range Ca19-9 were surgically explored. Perioperative outcome and survival of group 1 were compared with 44 patients primary resected for localized cancer with or without adjuvant treatment in the same time period (group 2). RESULTS Only one unresectable tumor was successfully resected compared to 7 out of 18 (39%) that were borderline resectable. Operations after chemoradiation were 1 hour longer and postoperative stays 5 days longer, but transfusion rate, morbidity, and mortality were not significantly different. Median survival was 15.4 months for group 1 (>21 for resected vs. 10 for not resected, P < 0.01) and 14 months for group 2. In both groups, a disease-free survival beyond 24 months was recorded only among patients resected with negative margins. CONCLUSIONS The conversion of an unresectable cancer to a resectable one is a rare event. On the contrary, the resection of a borderline resectable tumor was successfully accomplished in one-third of cases. Chemoradiotherapy did not increase the operative risk, but the interventions were more technically demanding and required a longer postoperative stay. Patients resected after chemoradiation for a locally advanced tumor had at least the same survival as those primary resected for a localized one. Only R0 resections in both groups gave the chance of disease-free survival longer than 24 months.

Abstract
PURPOSE More than 80% of patients who undergo a potentially curative resection for pancreatic cancer develop local or distant recurrence. Neoadjuvant chemoradiotherapy might offer potential benefits regarding local and systemic control and survival. This multi-institutional Phase II trial explored the feasibility of preoperative chemoradiation in this situation. METHODS AND MATERIALS Treatment consisted of concurrent radiotherapy (50 Gy within 5 weeks), and chemotherapy with 5-fluorouracil (300 mg/m(2)/day, 5 days/week, 5 consecutive weeks) and cisplatin (20 mg/m(2)/day, Days 1-5 and 29-33), followed by surgical resection of the pancreatic tumor in patients without progression. RESULTS A total of 41 patients were enrolled. Of these, 38 (93%) received > or =47 Gy; 30 patients (73%) received > or =75% of the prescribed doses of chemotherapy. Surgical resection was performed in 26 patients (63%). Because of local or metastatic progression, 5 patients (12%) did not undergo surgery and 10 underwent surgery without resection of the pancreatic tumor. Operative mortality was 2.8%. Among 40 evaluable patients, 27 were successfully treated (67.5%; 95% CI, 50.9-81.4%). CONCLUSIONS Pancreatic cancer is chemo-radiosensitive. The proposed pre-operative scheme is feasible, does not prevent successful surgery, and must be tested on a Phase III setting. Yet, the large proportion of tumor progression during and after chemoradiation justifies the use of more efficient drugs such as Gemcitabine, and optimized radiotherapy including new techniques such as intensity-modulated radiation therapy.

Abstract
Pancreatic cancer is a common, highly lethal disease with a rising incidence. In the last years continued efforts in pancreatic cancer research have led to a change in the classic approaches and to the development of new biological agents that appear to show promise. Adjuvant chemotherapy with gemcitabine has recently demonstrated better survival outcomes following surgical resection compared to no treatment, especially in patients with positive margins or lymph nodes. The addition of anti-VEGF agents to adjuvant regimens could improve long-term outcomes. In locally advanced disease, neoadjuvant regimens have not produced complete remissions, but partial responses have been reported ranging between 10 and 20%, with conflicting survival results. Combination trials with radiochemotherapy and new drugs appear well tolerated with encouraging preliminary results. In the metastatic setting, novel chemotherapeutic combinations and molecular targeted agents have shown promise in improving outcomes. To date, second line therapy is increasingly proposed and may even provide survival benefits in the future. This article summarizes the current standards of therapy for patients with resectable, advanced and metastatic pancreatic cancer.

Abstract
OBJECTIVES The aim of this study was to evaluate the possibility of subsequent resection of locally advanced pancreatic adenocarcinoma after chemotherapy and external-beam radiotherapy. PATIENTS AND METHODS Between January 1996 and January 2001, 33 consecutive patients (18 males and 15 women, mean age 63 years) with locally advanced PA were treated with chemotherapy and concurrent external-beam radiotherapy. Radiotherapy delivered 45-50.4 Gy, in a classical manner (N=27) or on a split-course (N=6). Chemotherapy was made of 5FU by continuous infusion for all patients during 5 weeks and cisplatin at the 1st and 5th weeks (N=22). Tumor resectability was reassessed at the end of the chemoradiotherapy; surgical resection of tumour was attempted in patients whose tumor demonstrated reduction in size, and supplementary radiotherapy of 10 to 15 Gy was delivered to the others. RESULTS Thirty-nine percent of patients experienced grade 3 acute toxicity. WHO criteria response to chemoradiotherapy four weeks after the end of treatment were: 4 partial responders (12%), 6 minor responders (18%), 14 stable disease (42%), 9 progression (28%). Ten patients underwent exploratory laparotomy, in one case vascular encasement did not allow for tumor resection, and in another patient, there was peritoneal carcinomatosis. In the 8 remaining patients, surgical (R0) resection was possible. In one patient histological examination showed fibrosis with no residual tumour. After a median follow-up period of 40 months, median survival was 16 months (66% and 37% of survival at 1 and 2 years respectively). In operated and non-operated patients, survival rates at 24 months were 73% and 12.5% respectively. At 1 year, 80% of the patients treated with radiochemotherapy developed recurrence, metastatic recurrence in 88%. Initial laparotomy, split course radiotherapy were poor outcome factors whereas chemotherapy appears to be a favorable outcome factor. CONCLUSION Subsequent resection of locally advanced pancreatic adenocarcinoma is possible after chemoradiotherapy allowing for a prolonged survival in some patients.

Abstract
BACKGROUND AND PURPOSE The majority of patients with pancreatic cancer have advanced disease at the time of diagnosis and are not amenable for surgery. Stereotactic radiotherapy (SRT) may be an alternative treatment for patients with locally advanced disease. The effect of SRT was investigated in the present phase-II trial. PATIENTS AND METHODS Twenty-two patients with locally advanced and surgically non-resectable, histological proven pancreatic carcinoma were included into the trial. The patients were immobilized by the Elekta stereotactic body frame (SBF) or a custom made body frame. SRT was given on standard LINAC with standard multi-leaf collimator. Central dose was 15 Gyx3 within 5-10 days. RESULTS Evaluation of response was found to be very difficult due to radiation and tumour related tissue reaction. Only two patients (9%) were found to have a partial response (PR), the remaining had no change (NC) or progression (PD) after treatment. Six patients had local tumour progression, but only one patient had an isolated local failure without simultaneous distant metastasis. Median time to local or distant progression was 4.8 months. Median survival time was 5.7 months and only 5% were alive 1 year after treatment. Acute toxicity reported 14 days after treatment was pronounced. There was a significant deterioration of performance status (P=0.008), more nausea (P=0.001) and more pain (P=0.008) after 14 days compared with base-line. However, 8 of 12 patients (66%) improved in performance status, scored less nausea, pain, or needed less analgesic drugs at 3 months after treatment. Four patients suffered from severe mucositis or ulceration of the stomach or duodenum and one of the patients had a non-fatal ulcer perforation of the stomach. CONCLUSIONS SRT was associated with poor outcome, unacceptable toxicity and questionable palliative effect and cannot be recommended for patients with advanced pancreatic carcinoma.

Abstract
BACKGROUND The importance of pancreatic cancer staging is uncertain. The aim of this report was to evaluate the accuracy of combined standard imaging techniques in predicting the pathologic stage and to evaluate the prognostic effect of clinical staging to identify patient groups in which laparoscopy and laparotomy could be beneficial. METHODS Fifty-four patients were included in this analysis. The techniques used for clinical staging were endoscopic retrograde cholangiopancreatography, abdominal computed tomographic scan, and ultrasonography. All patients underwent both clinical and surgical/pathologic staging. A comparison was performed between presurgical stage and surgical/pathologic stage. The prognostic effect of different factors on survival was evaluated with both univariate (log-rank) and multivariate (Cox) analysis. RESULTS Sensitivity and specificity for vascular involvement were 73.9% and 96.3%, respectively. Sensitivity and specificity for nodal involvement were 63.6% and 95.4%, respectively. A total of 33.3% of patients showed a higher than expected pathologic stage, and 3.7% showed a lower than expected pathologic stage, by comparing clinical and pathologic evaluation. A highly significant correlation was observed between clinical T stage (P = .0067) and tumor diameter (P = .0037) and patient survival. Maximal prognostic differentiation was observed by dividing patients into two groups based on imaging results: group A (favorable prognosis) and group B (unfavorable prognosis). The median survival was 25.1 and 8.0 months for group A and B, respectively. Five-year survival was 20.1% and 0%, respectively (multivariate analysis: P = .0007). CONCLUSIONS Integrated standard imaging studies achieved reasonable diagnostic accuracy in our analysis. A single classification based on clinical stage and tumor diameter evaluated by imaging predicts prognosis in patients with pancreatic carcinoma.

Abstract
PURPOSE A Phase I-II dose-escalation study was performed to evaluate the possible impact of the dose on response, toxicity, pain relief, and outcome in patients with unresectable pancreatic carcinoma. METHODS AND MATERIALS A total of 50 patients entered the study. The external beam radiotherapy (RT) dose was 39.6 Gy in the first 15 patients, 50.4 Gy in the next 15 patients, and 59.4 Gy in the remaining 20 patients, at five 1.8-Gy fractions weekly. During external beam RT, patients received concurrent continuous infusion of 5-fluorouracil (1000 mg/m(2) on Days 1-4 and 21-24). Patients were evaluated for toxic reactions, local disease control, survival, and pain relief. RESULTS No treatment-related deaths occurred from acute toxicity. Four patients required a temporary treatment interruption because of acute hematologic (2 patients) or GI (2 patients) toxicity, not correlated with the delivered RT dose. Three patients (6%) developed late toxicity (duodenal ulcer in 2 and duodenal stenosis in 1). All patients who developed late toxicity had received a dose of 59.4 Gy. At univariate analysis, only the RT dose correlated significantly with the incidence of late toxicity (at 2 years, 39.6-50.4 Gy resulted in 0% and 59.4 Gy resulted in 58.2%; p = 0.023). At multivariate analysis, the RT dose also showed a trend with the incidence of late side effects (p = 0.052). Overall, 6 patients had a partial response (12%) and 44 (88%) had no change. The overall response rate was 8.0% (95% confidence interval, 1.5-20.5%). The rate of response was not different in the three groups. In-field locoregional disease progression was seen in 7 patients (14.0%). Distant relapse was documented in 34 patients (68.0%). None of analyzed variables, in particular, the RT dose delivered, showed a statistically significant correlation with objective response, local control, incidence of metastasis, disease-free survival, or overall incidence of pain symptoms after therapy. The whole group median survival was 9 months. The actuarial survival rate at 1, 2, and 3 years was 31.3%, 2.8%, and 0.0%, respectively. None of analyzed parameters correlated significantly with survival at univariate or multivariate analysis. CONCLUSION In a Phase I-II study, the association of high RT doses with the incidence of severe toxicity in the treatment of unresectable pancreatic carcinoma was confirmed. Furthermore, this dose-escalation study did not document a clearcut correlation, using 5-fluorouracil-based chemoradiation, between the radiation dose and clinical outcome.

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
The combination of gemcitabine with concurrent radiation therapy (Gem/RT) is a promising new approach that is being investigated in patients with unresectable pancreatic cancer. However, substantial toxicity with this combination has also been observed. This review was conducted to determine whether Gem/RT could be safely delivered in the neoadjuvant setting, based on our experience with this combined therapy in a cohort of patients with previously unresectable pancreatic cancer, who subsequently underwent surgical resection. Between July 1996 and June 2001, a total of 67 patients with locally unresectable pancreatic cancer, without distant metastatic disease, received Gem/RT at our institution. Seventeen patients (25%) underwent exploratory surgery following Gem/RT, and nine underwent standard Whipple resection. Thus 9 (52%) of 17 patients who had exploratory operations or 9 (13%) of 67 patients, underwent surgical resection. Thirty-day mortality after resection was 0%, and there were no major surgical complications. Median length of hospital stay was 14 days (range 11 to 19 days). With a median follow-up of 32 months, median survival for the resected patients was 17.6 months (95% confidence interval 12.6 to 37.3 months). Median survival for the remaining 58 patients was 11.9 months (95% confidence interval 9.6 to 14.7 months, P=0.013). We conclude that surgical resection may be safely performed after Gem/RT in a select group of patients initially considered to have unresectable pancreatic cancer. The use of Gem/RT in a neoadjuvant setting is currently being investigated in a multi-institutional phase II trial.

Abstract
Prognosis of pancreatic carcinoma remains poor, with one-year and five-year overall survival rates of 20 and 5% respectively. Only 5 to 15% of patients present with tumors amenable to resection. Long-term (5 years) survival after curative resection is less than 20%, and the median survival is about 12 months. This paper updates recent trends about concomitant chemoradiation. At first, a review of the studies on adjuvant chemoradiation after surgery is proposed. Then, indications of preoperative chemoradiation for patients with localized resectable adenocarcinoma are discussed. The last part concerns the most important and recent studies about chemoradiation in locally advanced pancreatic cancer, either with 5-fluoro-uracile or based on new drugs like gemcitabine.

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
PURPOSE Maximal therapeutic gain in xenograft sarcoma and toxicity for jejunal mucosa is time dependent for concurrent gemcitabine and radiotherapy (RT). We used a time-dependent schedule to determine the maximal-tolerated dose and dose-limiting toxicities (DLTs; Grade 4 hematologic or Grade 3 other toxicity). METHODS AND MATERIALS Patients with pancreatic cancer (n = 33), periampullary carcinoma (n = 1), or bile duct cancer (n = 2) were treated with 3-day conformal RT with 50.4 Gy (tumor, lymphatics) plus a 5.4-Gy boost. Concurrent cisplatin (20 mg/m(2)/d on Days 1-5 and 29-33) and gemcitabine (initially 600 mg/m(2), weekly on Fridays 68 h before RT) were administered. Because of DLT, the doses were reduced to 500 mg/m(2) weekly and then 500, 400, or 300 mg/m(2) on Days 2, 5, 26, 33. RESULTS DLT occurred at all dose levels of gemcitabine >300 mg/m(2). Fourteen patients were treated at the recommended Phase II dose of gemcitabine (300 mg/m(2)) without DLT. The response to chemoradiation allowed 10 of 30 initially unresectable patients with primary pancreatic carcinoma to undergo radical surgery, including a complete response in 2 cases. CONCLUSIONS At the recommended Phase II dose, chemoradiation with gemcitabine and cisplatin can be administered safely in pancreatic carcinoma. However, at higher dose levels, toxicity is severe and frequent. Patients with a chance for conversion to resection could benefit from this schedule.

Abstract
BACKGROUND AND OBJECTIVES Gemcitabine is an active agent in pancreatic cancer, with known radiosensitizing properties. Therefore, a phase II study was conducted to evaluate the efficacy of gemcitabine combined with radiation therapy in patients with localized unresectable adenocarcinoma of the pancreas. METHODS Weekly gemcitabine at a dose of 1,000 mg/m(2) for 7 weeks was given as an induction phase. Patients who showed both clinical benefit response (CBR) and reduced or stable tumor size on computed tomography (CT) scan entered the chemoradiotherapy phase of the treatment. This consisted of gemcitabine 400 mg/m(2) weekly x3 every 28 days for 2 cycles, given concurrently with radiotherapy, for a total dose of 50.4 Gy in 28 fractions. After completion of radiotherapy, gemcitabine was continued as maintenance. RESULTS Twenty patients entered this study. Ten patients (50%) achieved CBR to gemcitabine in the induction phase; these patients had no objective tumor progression and were therefore enrolled in the chemoradiotherapy phase. Four patients (20%) had a partial response, and three patients (15%) underwent pancreatectomy. Two patients had negative surgical margins, and in one patient histologic examination of the residual mass showed only fibrosis. The median survival for the entire group was 8 months, and the median survival has not yet been reached for the chemoradiotherapy group. CONCLUSIONS Treatment with gemcitabine concomitant with radiation therapy according to the present schedule is well tolerated and can provide prolonged CBR and disease stabilization in patients with localized, unresectable pancreatic cancer.

Abstract
BACKGROUND Resection of pancreatic adenocarcinoma has a limited impact on survival. We hypothesized that delivering preoperative radiochemotherapy (RTCT) might enhance local control of the cancer and improve survival. METHODS Nineteen patients with localized pancreatic cancer (14 head and 5 body) were treated during the past 4 years with an intramural protocol consisting of continuous infusion of fluorouracile (5-FU: 650 mg/m(2)/D1-D5 and D21-D25 and Cisplatin 80 mg/m(2)/bolus D2 and D22 with preoperative external beam radiotherapy (RT) (30Gy split course RT or 45 Gy standard fractionation RT). RESULTS Four patients did not have surgical resection: Three patients were noted to have liver metastases and 1 patient developed peritoneal carcinomatosis. The remaining 15 patients had potentially curative resection (12 Whipple procedure and 3 distal subtotal pancreatectomy). There was no postoperative death. Pathologic findings showed five major responses including 2 patients with complete pathologic response. The overall median survival for the 19 study patients was 20 months. The median disease free and 2-year overall survival for the group with resection were 30 months and 52.3%. CONCLUSIONS Preoperative RTCT followed by resection is well-tolerated and safe for patients with localized pancreatic cancer. Major histological response occurred for 25% of patients. This approach could offer improvement in patient survival.

Abstract
Treatment of pancreatic cancer remains a challenging task that often requires a multidisciplinary approach to confer optimal response and, ideally, maximize survival. A combination of locoregional approaches such as surgery and radiotherapy, along with systemic therapies for eradication of micrometastases, should be considered both for patients who are operative candidates and for those with locally advanced, unresectable disease. How best to combine these modalities in terms of schedule, timing, and choice of agents is a question that continues to be actively investigated. Some of these data are equivocal or conflicting; thus standards of care for combined-modality treatment have not been uniformly accepted to date. This article provides an overview of combined-modality therapy, focusing on the major studies that have guided our current approach to the treatment of pancreatic cancer and examining new strategies that are likely to improve outcomes and survival for patients in the future.

Abstract
The survival of patients diagnosed with pancreatic cancer is dismal. Few patients on initial presentation are suitable for surgical resection. This has prompted clinical studies with chemotherapy and/or radiotherapy designed either to increase the number of patients eligible for surgery (neoadjuvant therapy) or to prolong the survival of patients who had undergone surgery (adjuvant therapy). None of these studies may at this time be considered definitive. Wherever possible, patients felt eligible for neoadjuvant or adjuvant therapy should be entered on clinical trials. Where this is not possible, clinicians should exercise their best judgment in offering this type of treatment to pancreatic cancer patients under their care.

Abstract
Pancreatic cancer is one of the deadliest malignancies and is fatal in more than 95% of affected individuals. For locally advanced disease, the combination of 5-FU and radiation appears to offer the best chance for delaying disease progression. The introduction of gemcitabine into chemoradiotherapy regimens may provide additional improvements in the management of patients. Preoperative therapy has proved feasible but has not shown improvement in overall survival.

Abstract
BACKGROUND The use of neoadjuvant (preoperative) chemoradiotherapy (CRT) for pancreatic cancer has been advocated for its potential ability to optimize patient selection for surgical resection and to downstage locally advanced tumors. This article reports our experience with neoadjuvant CRT for localized pancreatic cancer. METHODS Since 1995, 111 patients with radiographically localized, pathologically confirmed pancreatic adenocarcinoma have received neoadjuvant external beam radiation therapy (EBRT; median, 4500 cGy) with 5-flourouracil-based chemotherapy. Tumors were defined as potentially resectable (PR, n = 53) in the absence of arterial involvement and venous occlusion and locally advanced (LA, n = 58) with arterial involvement or venous occlusion by CT. RESULTS Five patients (4.5%) were not restaged due to death (n = 3) or intolerance of therapy (n = 2). Twenty-one patients (19%) manifested distant metastatic disease on restaging CT. Twenty-eight patients with initially PR tumors (53%) and 11 patients with initially LA tumors (19%) were resected after CRT. Histologic examination revealed significant fibrosis in all resected specimens and two complete responses. Surgical margins were negative in 72%, and lymph nodes were negative in 70% of resected patients. Median survival in resected patients has not been reached at a median follow-up of 16 months. CONCLUSIONS Neoadjuvant CRT provided an opportunity for patients with occult metastatic disease to avoid the morbidity of resection and resulted in tumor downstaging in a minority of patients with LA tumors. Survival after neoadjuvant CRT and resection appears to be at least comparable to survival after resection and adjuvant (postoperative) CRT.

Abstract
PURPOSE To determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of twice-weekly gemcitabine (TW-G) when administered in conjunction with fixed dose amifostine (A) during external radiotherapy (RT) in patients with advanced pancreatic cancer. METHODS AND MATERIALS Ten patients with previously untreated, locally advanced, or asymptomatic-metastatic pancreatic adenocarcinoma were enrolled in this study. RT was delivered by using the standard four-field technique (1.8 Gy daily fractions, 45 Gy followed by a boost of 5.4 Gy, in 5-1/2 weeks). The starting dose of TW-G was 60 mg/m(2) (i.v., 30-min infusion), which is equal to the upper limit of previously reported MTD of TW-G when given without A during RT. A was given just before the TW-G, at a fixed dose of 340 mg/m(2) (i.v., rapid infusion). TW-G doses were escalated by 30-mg/m(2) increments in successive cohorts of 3 to 6 additional patients until DLT was observed. Toxicities were graded using the Radiation Therapy Oncology Group and National Cancer Institute Common Toxicity Criteria, version 2.0. RESULTS In general, therapy was well tolerated in patients treated at the first two dose levels of 60 mg/m(2) and 90 mg/m(2). The DLT of TW-G given in conjunction with A during RT were neutropenia, thrombocytopenia, and nausea/vomiting at the dose level of 120 mg/m(2). Of the 10 patients eligible for a median follow-up of 10 months, 5 remain alive; 1 complete responder, 3 partial responders, and 1 with stable disease. CONCLUSION A dose of TW-G at a level of 90 mg/m(2) produced tolerable toxicity and it may possess significant activity when delivered in conjunction with 340 mg/m(2) dose of A during RT of the upper abdomen. Due to the higher MTD of TW-G seen in our study, we consider that the A supplementation may optimize the therapeutic index of TW-G-based chemoradiotherapy protocols in patients with pancreatic carcinoma.

Abstract
BACKGROUND AND OBJECTIVES The combination of 5-fluorouracil and radiotherapy is thought to be the most effective treatment for locally unresectable pancreatic carcinoma. The outcomes, however, are far from acceptable from the viewpoint of long-term survival. We assessed the survival benefits of oral adjuvant chemotherapy with doxifluridine (5'-DFUR) following radiotherapy for patients with the disease. METHODS Thirty-five consecutive patients who underwent bypass surgery and radiotherapy for localized advanced unresectable adenocarcinoma of the pancreas head were retrospectively reviewed in regard to disease progression and survival. Ten of the 35 patients underwent adjuvant chemotherapy with 5'-DFUR after radiotherapy in an outpatient setting. RESULTS The 1-year survival for patients treated with radiotherapy alone was 29%. The 1-, 2-, and 3-year survivals for patients treated with the adjuvant chemotherapy after radiotherapy were 50, 40, and 30%, respectively (P = 0.0069, log-rank test). The elevation of tumor markers was delayed (P = 0.0346) and local control rate was improved (P = 0.0475) in patients with chemotherapy. Multivariate analysis demonstrated that the adjuvant chemotherapy with 5'-DFUR was a significant independent prognostic factor as well as tumor size. CONCLUSIONS The adjuvant chemotherapy with 5'-DFUR following radiotherapy led to a significant prolongation of the survival for patients with unresectable localized pancreatic cancer.

Abstract
Chemoradiotherapy for unresectable LAPA is associated with a median survival time of 9 months or more and manageable toxic side effects. Experience with RT-FSP provides evidence that chemoradiotherapy may extend survival time with or without resection. Chemoradiotherapy or entry into clinical trials is the standard for LAPA. The next generation of clinical trials for LAPA will incorporate newer agents, such as gemcitabine and irinotecan into chemoradiotherapy regimens. Novel agents, such as matrix-metaloproteinase inhibitors, transcription factor inhibitors, antiangiogenic factors, cyclooxegenase-2 inhibitors, and agents that target the K-ras point mutations associated with 90% of pancreatic cancers, are in early phases or clinical development and may have activity for micrometastic or minimal residual disease. Lower toxicity makes these drugs attractive agents for maintenance therapies. The multitude of new agents provides hope to patients and a welcome challenge for further investigation.

Abstract
PURPOSE: To evaluate the efficacy and toxicity of a cisplatin, epirubicin, gemcitabine, and fluorouracil (PEF-G) schedule on stage IV pancreatic adenocarcinoma. PATIENTS AND METHODS: Patients ≤ 70 years, with no prior chemotherapy and with bidimensionally measurable stage IV pancreatic adenocarcinoma, Eastern Cooperative Oncology Group performance status ≤ 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. RESULTS: 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. CONCLUSION: 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.
