Abstract
We report the case of a 64-year-old woman treated for a locally advanced pancreatic adenocarcinoma, which could not undergo radical resection due to encasement of the superior mesenteric artery. After chemoradiotherapy (six weeks), normalization of plasma CA19.9 levels was documented and CT showed shrinkage of the pancreatic mass but persistent encasement of the SMA. Surgical exploration followed by radical resection was performed 18 months later. Resection of the pancreatic head was then performed and the final pathological analysis showed a complete response. This case is unique in terms of the duration of follow-up between chemoradiotherapy and radical resection and raises two main concerns regarding the current standard of care of locally advanced pancreatic tumors; first, the difficulty of assessing the tumor response to chemoradiotherapy, second, the unfeasibility of establishing the timing of surgery, its indications and the survival benefits for patients with an objective response to therapy.

Abstract
AIMS The outcome of patients with pancreatic cancer from an unselected population within a UK region has not previously been reported. We undertook a review of pancreatic cancer in southeast Wales, with an emphasis on locally advanced non-metastatic pancreatic cancer (LANPC) in an attempt to define a subgroup of patients who would probably benefit from multi-modality treatment. MATERIALS AND METHODS Case notes of patients referred to Velindre Hospital between 1 January 2002 and 31 December 2005 were reviewed. Data on patient demographics, tumour characteristics, treatment, treatment response and overall survival were collected. The Log-rank test was used to compare survival between groups and Cox regression was used to evaluate whether age, gender, tumour site and treatment response correlated with overall survival in LANPC. RESULTS Of the 354 referrals (complete data on 315 patients), 93% were inoperable and 51% of inoperable patients received active treatment (149/294). One hundred and fourteen patients out of 315 (36%) had LANPC and 72/114 (64%) were fit for active treatment, including chemotherapy (n=66) and chemoradiotherapy (CRT) (n=6). The median survival of patients with LANPC was 7.4 months (95% confidence interval 6.4-8.5). Survival for patients receiving chemotherapy, CRT and no treatment was 9.2 (7.5-10.7), 12.6 (6.1-19.1) and 4.5 (3.7-5.3) months, respectively. Overall survival of patients who had non-progressive disease after initial chemotherapy was significantly better than those who progressed (11.8 vs 6.6 months, P=0.01). Of the 180/315 (57%) patients presenting with metastatic disease, 43% received active treatment. Overall survival of metastatic patients was 2.8 months (2.3-3.2 months); for those receiving active treatment, this was 5.6 months (5.1-6.1 months) and for those receiving active supportive care 1.8 months (1.6-2.0 months). CONCLUSIONS In this UK network, about half of the patients received active treatment. Although the overall outcome was poor, that of treated patients was comparable with published studies. For patients with LANPC, the initial response or disease stabilisation on chemotherapy defined a subset of patients who had better outcome. The role of CRT over and above chemotherapy needs to be defined through trials that should include a neoadjuvant 'chemotherapy-only' phase to select out patients who benefit from multi-modality treatment.

Abstract
Pancreatic cancer remains a significant therapeutic challenge in oncology as the 21st century begins. Currently available cytotoxic chemotherapeutic agents provide only a modest survival benefit for patients with advanced disease. Recent efforts to improve survival in the setting of locally advanced and metastatic disease have focused on combinations of cytotoxic agents and the integration of newer molecular agents. To date, these strategies have been somewhat disappointing, prompting some experts to consider changes in clinical trial design with more rigorous patient eligibility criteria. In the adjuvant therapy setting, investigation of newer agents has lagged behind studies in more advanced disease, but recent results suggested some evidence of incremental advance. However, just as in advanced pancreatic cancer, without a more disciplined approach to patient selection for surgical intervention and subsequent adjuvant therapy, progress can be expected to remain very slow. This review will provide a brief summary of the history of chemotherapy in the treatment of pancreatic cancer and focus on its current and future role in adjuvant therapy.

Abstract
BACKGROUND Pancreatic cancer remains a difficult disease to treat. Diagnosis at an early stage may allow curative treatment with resection. In the past, the mortality associated with surgical treatment of pancreatic carcinoma was prohibitive but mortality associated with resection is now commensurate with all other major oncologic resections. Thus, the focus of surgical management has shifted to address several issues: the diagnosis and evaluation of patients with suspected pancreatic cancer, the role of preoperative endobiliary stenting, the role of laparoscopy, the extent of resection, the role of adjuvant and neoadjuvant treatment, and the role of specialized centers in treating the disease. METHODS The current literature is reviewed to address these issues and help guide physicians who first encounter patients with suspected pancreatic cancer as well as surgeons who ultimately resect them. Practical evidence-based information to guide the decision-making process is provided. RESULTS Surgical morbidity and mortality have achieved parity with other types of major oncologic resection, and a distinct survival advantage is possible when such therapy is applied early in the disease stage. Issues regarding the use of stents, extent of resection, and pre- vs post-operative chemoradiation therapy are becoming clearer as our collective experience broadens. CONCLUSIONS Surgical treatment of pancreatic cancer should be aggressively pursued given the clearly established survival advantage and relief of symptoms achieved when it is applied appropriately.

Abstract
Neoadjuvant chemoradiotherapy can be administered safely to patients with pancreatic cancer. Complete pathologic responses are rare, however, and the benefits of this approach compared with standard adjuvant therapy are uncertain. The only way to evaluate the efficacy of neoadjuvant chemoradiotherapy is a prospective trial involving a uniform patient population comparing the results of neoadjuvant and adjuvant therapy and a cohort receiving surgery alone. Such a study can be designed in an ethically sound manner but requires the collaboration of numerous institutions and careful coordination to achieve statistically conclusive results. The future of pancreatic cancer research rests on the availability and rapid transfer of new therapies from the laboratory to clinical research.

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
UNLABELLED Induction chemoradiotherapy (CRT) may downstage locally advanced pancreatic tumors but secondary resections are unfrequent. However some responders' patients may benefit of a R0 resection. PATIENTS AND METHODS We report 18 resections among 29 locally advanced pancreatic cancers; 15 patients were treated with neoadjuvant 5-FU-cisplatin based (13) or taxotere based (2 patients) chemoradiotherapy (45 Gy), and 3 patients without histologically proven adenocarcinoma were resected without any preoperative treatment. RESULTS The morbidity rate was 28% and the mortality rate was 7%; one patient died after resection (5.5%) and one died after exploration (9%). The R0 resection rate was 50%. The median survival for the resected patients was not reached and the actuarial survival at 3 years was 59%. Two specimens showed no residual tumor and the two patients were alive at 15 and 46 months without recurrence; one specimen showed less than 10% viable tumoral cells and the patient was alive at 36 months without recurrence. A mesenteric infarction was the cause of a late death at 3 years in a disease free patient (radiation induced injury of the superior mesenteric artery). The median survival of the 11 non-resected patients was 21 months and the actuarial survival at 2 years was 0%. When the number of the resected patients (18) was reported to the entire cohort of the patients with locally advanced pancreatic cancer treated during the same period in our institution, the secondary resectability rate was 9%. CONCLUSION Preoperative chemoradiotherapy identifies poor surgical candidates through observation and may enhance the margin status of patients undergoing secondary resection for locally advanced tumors. However it remains difficult to evaluate the results in the literature because of the variations in the definitions of resectability. The best therapeutic strategy remains to be defined, because the majority of patients ultimately succumb with distant metastatic disease.

Abstract
BACKGROUND Theoretical benefits of preoperative chemoradiation therapy (preop CRT) for pancreatic cancer include improved efficacy, resectability, and patient selection. The goal of this study was to evaluate the applicability of a nomogram, which was developed for patients undergoing resection without preop CRT and which incorporates several post-resection pathological factors, to a population of patients who received preop CRT prior to resection. METHODS From 1994 to 2004, 82 patients with biopsy-proven, radiographically localized adenocarcinoma of the pancreatic head underwent preop CRT followed by pancreaticoduodenectomy (PD); 50 concurrent patients underwent PD without preop CRT. Mean nomogram-predicted disease-specific survival (DSS) rates were compared with observed DSS rates from the time of resection. RESULTS Despite having more locally advanced tumors on initial staging (21 vs. 8%; P < .05), patients who received preop CRT had smaller resected tumors (mean 2.3 vs. 3.1 cm; P < .01), were less likely to have T3 tumors (54 vs. 80%, P < .01), were less likely to have positive lymph nodes (29 vs. 58%, P < .01), and had fewer positive lymph nodes (mean .4 vs. 1.9, P < .01), all factors that imply treatment effect and favorably impact on nomogram-predicted DSS. Observed DSS was similar to predicted DSS in both groups. CONCLUSIONS The similarity in observed and predicted DSS following resection in patients who received preop CRT suggests that the effects of preop CRT-whether treatment, selection, or no effect-are reflected by the nomogram. The ability of the nomogram to evaluate the effects of preop CRT on survival is limited by the potential effects of preop CRT on factors within the nomogram.

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
BACKGROUND & AIMS The endogenous opioid system is involved in modulating the experience of pain, the response to stress, and the action of analgesic therapies. Recent human imaging studies have shown a significant tonic modulation of visceral pain, raising the question of whether endogenous opioids tonically modulate the pain of visceral cancer. METHODS Transgenic mice expressing the first 127 amino acids of simian virus 40 large T antigen, under the control of the rat elastase-1 promoter, that spontaneously develop pancreatic cancer were used to investigate the role of endogenous opioids in the modulation of pancreatic cancer pain. Visceral pain behaviors were assessed as degree of hunching and vocalization. RESULTS Although mice with late-stage pancreatic cancer displayed spontaneous, morphine-reversible, visceral pain-related behaviors such as hunching and vocalization, these behaviors were absent in mice with early-stage pancreatic cancer. After systemic administration of the central nervous system (CNS)-penetrant opioid receptor antagonists naloxone or naltrexone, mice with early-stage pancreatic cancer displayed significant visceral pain-related behaviors, whereas systemic administration of the CNS-nonpenetrant opioid antagonist naloxone-methiodide did not induce an increase in visceral pain behaviors. CONCLUSIONS Our findings suggest that a CNS opioid-dependent mechanism tonically modulates early and late-stage pancreatic cancer pain. Understanding the mechanisms that mask this pain in early stage disease and drive this pain in late-stage disease may allow improved diagnosis, treatment, and care of patients with pancreatic cancer.

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
BACKGROUND We report the results of a multi-institutional phase II trial that used preoperative full-dose gemcitabine and radiotherapy for patients with potentially resectable pancreatic carcinoma. METHODS Patients were treated before surgery with three cycles of full-dose gemcitabine (1000 mg/m2 intravenously), with radiation during the second cycle (36 Gy in daily 2.4-Gy fractions). Patients underwent surgery 4 to 6 weeks after the last gemcitabine infusion. RESULTS There were 10 men and 10 women, with a median age of 58 years (range, 50-80 years). Nineteen patients (95%) completed therapy without interruption, and one experienced grade 3 gastrointestinal toxicity. The mean weight loss after therapy was 4.0%. Of 20 patients taken to surgery, 17 (85%) underwent resections (16 pancreaticoduodenectomies and 1 distal pancreatectomy). The complication rate was 24%, with an average length of stay of 13.5 days. There were no operative deaths. Pathologic analysis revealed clear margins in 16 (94%) of 17 and uninvolved lymph nodes in 11 (65%) of 17 specimens. One specimen contained no residual tumor, and three specimens revealed only microscopic foci of residual disease. With a median follow-up of 18 months, 7 (41%) of the 17 patients with resected disease are alive with no recurrence, 3 (18%) are alive with distant metastases, and 7 (41%) have died. CONCLUSIONS Preoperative gemcitabine/radiotherapy is well tolerated and safe when delivered in a multi-institutional setting. This protocol had a high rate of subsequent resection, with acceptable morbidity. The high rate of negative margins and uninvolved nodes suggests a significant tumor response. Preliminary survival data are encouraging. This regimen should be considered in future neoadjuvant trials for pancreatic cancer.

Abstract
In spite of the high mortality in pancreatic cancer, significant progress is being made. This review discusses multimodality therapy for patients with pancreatic cancer. Surgical therapy currently offers the only potential monomodal cure for pancreatic adenocarcinoma. However, only 10-20% of patients present with tumors that are amenable to resection, and even after resection of localized cancers, long-term survival is rare. The addition of chemoradiation therapy significantly increases median survival. To achieve long-term success in treating this disease it is therefore increasingly important to identify effective neoadjuvant/adjuvant multimodality therapies. Preoperative chemoradiation for potentially resectable pancreatic cancer has the following advantages: (1) neoadjuvant treatment would eliminate the delay of adjuvant treatment due to postoperative complications; (2) neoadjuvant treatment could avoid unnecessary surgery for patients with metastatic disease evident on restaging after neoadjuvant therapy; (3) down-staging after neoadjuvant therapy may increase the likelihood of negative surgical margins; and (4) neoadjuvant treatment could prevent peritoneal tumor cell implantation and dissemination caused during surgery. This review systematically summarizes the current status, controversies, and prospects of neoadjuvant treatment of pancreatic cancer.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (neo-CRT) is being used with increasing frequency for periampullary tumors, but how it alters the complication rate of pancreaticoduodenectomy (PD) is unclear. METHODS A retrospective analysis was conducted of 79 patients with periampullary malignancies who received 5-fluorouracil-based neo-CRT followed by PD. RESULTS There was no difference in mortality between PD after neo-CRT (3.8%) and conventional PD for either malignant (4.5%) or benign (2.2%) disease. Focusing only on patients with malignancy, the neo-CRT group had a significantly lower pancreatic leak rate than the conventional group (10% vs. 43%; P < .001). Intra-abdominal abscesses were less common in the neo-CRT group (8.8% vs. 21%; P = .019), and there was one (1.2%) amylase-rich abscess in neo-CRT group, compared with eight (12%) in the conventional group. In addition, two patients in the conventional group died of leak-associated sepsis, compared with none in the neo-CRT group. Multivariate analysis revealed that neoadjuvant chemoradiation (odds ratio, .15) was the most significant factor associated with a reduced risk of pancreatic leak. CONCLUSIONS Neo-CRT does not increase the mortality or morbidity of PD. In contrast, neo-CRT was associated with a marked reduction in the incidence of pancreatic leak, as well as leak-associated morbidity and mortality.

Abstract
Exocrine pancreatic cancer (pancreatic ductal adenocarcinoma) is one of the leading causes of cancer deaths in the western world, accounting for 5% of all cancer-related deaths. Only a small percentage of patients with pancreatic cancer are able to undergo potentially curative resection, even in specialized centres, and prognosis remains poor after successful surgery. Over the last few years efforts have been directed towards the development of adjuvant therapies in attempts to improve outcome. The main trials of adjuvant chemotherapy, chemoradiotherapy and chemoradiotherapy with follow-on chemotherapy are described in this paper, followed by the results of the ESPAC-1 trial and the status of ESPAC-2 and -3 trials.

Abstract
The study goal was to determine the technical feasibility and outcomes associated with pancreaticoduodenectomy for periampullary malignancies with near (>80%) or complete (100%) superior mesenteric venous (SMV) obstruction. A retrospective examination of 11 patients with high-grade or complete SMV obstruction who underwent pancreaticoduodenectomy at five academic medical centers is reviewed. Pancreaticoduodenectomy for locally advanced periampullary malignancies causing high-grade or complete SMV obstruction is technically feasible. Operative approaches and outcomes are presented. One 30-day death was observed. Median survival of the cohort is 18 months. Survivals exceeding 2 years post-resection have been observed. In a number of cases, significant palliation of pain and of biliary and duodenal obstruction were achieved. Based on this initial series, pancreaticoduodenectomy in the presence of near or total SMV obstruction is feasible, may result in an R0 resection, and may be beneficial in select patients with a periampullary malignancy. We suggest such an approach be considered particularly following completion of neoadjuvant therapy without systemic progression. Further studies and more long-term follow-up at high-volume centers are required, however, to better determine the indications and potential benefit of such an undertaking.

Abstract
There are relatively few randomized studies of adjuvant chemoradiotherapy and chemotherapy in patients with resected pancreatic adenocarcinoma. The European Study Group for Pancreatic Cancer 1 (ESPAC1) trial is the largest study of adjuvant treatment to date. The results of ESPAC1 are discussed in the context of other evidence from previous randomized studies, which have also been combined in a meta-analysis. Overall, the existing data show a clear benefit for postoperative adjuvant chemotherapy, which has not been demonstrated for adjuvant chemoradiotherapy. The subgroup of patients with resection margin positive disease did seem to benefit less from adjuvant chemotherapy, and showed a trend towards improved survival with chemoradiotherapy. Adjuvant chemoradiotherapy should be evaluated further in this latter group of patients. The optimal chemotherapy regimen for use as adjuvant treatment is the subject of ongoing trials. Other strategies which should be explored include neoadjuvant treatment and the incorporation of novel targeted agents into management.

Abstract
BACKGROUND The outcome after resection of advanced pancreatic cancers is extremely poor because of the high incidence of the postoperative development of liver metastasis and local recurrence. We performed a combination of chemoradiation and liver perfusion chemotherapy and extended pancreatectomy. METHODS Nineteen patients with T3 pancreatic head cancers were enrolled. A total of 24 Gy in 12 fractions of 10-MV x-rays with a concurrent intravenous infusion of 5-fluorouracil (5-FU; 3 g/12 days) was administered to the pancreatic head area. An extended pancreaticoduodenectomy was performed, and catheters were placed into the gastroduodenal artery and the superior mesenteric vein. During the first 28 postoperative days, 5-FU was continuously infused via the hepatic artery and portal vein (3.5 g/28 days x 2). Finally, 36 Gy in 18 fractions with 5-FU (3 g/6 days) was applied to the pancreatic bed. RESULTS After preoperative chemoradiation, four patients did not undergo surgical resection because of distant metastases. Fifteen patients underwent pancreaticoduodenectomy, liver perfusion chemotherapy, and postoperative chemoradiation. No patient developed grade 3 toxicity as a result of preoperative chemoradiation, but one patient (7%) developed grade 3 leukopenia during the postoperative treatments. The morbidity rate was 20% (3 of 15 patients), and the mortality rate was 0%. The overall 3-year survival rate was 53%. The 3-year disease-free survival rate was 66% in patients who pathologically responded well (>50%), versus 0% in patients with poor responses (P = .04). CONCLUSIONS A combination of preoperative and postoperative chemoradiation plus postoperative liver perfusion chemotherapy with an extended pancreatectomy is feasible, and the long-term outcomes are also promising.

Abstract
Advances in minimally invasive surgery have revolutionized the field of surgery. Despite the great strides in equipment and experience, operative conduct remains confined by the limits of exposure. Retroperitoneal fat can be abundant and can contribute greatly to difficulty in exposure. Visceral organs ventral to the retroperitoneum preclude direct access and require optimal patient positioning to operate. Additionally, the major vascular pedicles all originate in the retroperitoneum off of the abdominal aorta or enter the inferior vena cava. The pancreas, in particular, is surrounded by the portal vein, celiac axis, superior mesenteric vein and artery, and splenic vein and artery. If injured during surgery, these vessels can present a life-threatening emergency. The issues related to the vasculature, coupled with the difficulty in resecting portions of the pancreas and the relative paucity of pancreatic procedures, have greatly concentrated these cases at tertiary care centers staffed by experienced laparoscopists. However, as surgical technology improves and fellowships train more surgeons with advanced laparoscopic skills, minimally invasive pancreatic surgery may diffuse with more community-based health care networks.

Abstract
INTRODUCTION The accuracy of endoscopic ultrasound (EUS) for the diagnosis and staging of pancreatic ductal adenocarcinoma (PDA) has been confirmed. Chemo-radiotherpay (CRT) induces tumor changes which can limit the accuracy of EUS. The aim of our study was to analyze the efficacy of EUS following neoadjuvant CRT comparing findings with the pathology results. PATIENTS AND METHODS From November 1996 to October 2003, 45 patients with histologically proven and EUS-staged PDA were treated with neo-adjuvant CRT and radical surgery. All were restaged before surgery using both EUS and computed tomography. Fifteen patients were found to have developed distant metastases. Thirty patients finally underwent pancreaticoduodenectomy (N=24) or distal pancreatectomy (N=6). RESULTS Following CRT, tumor stage was correctly assessed in 12 patients (40%). The most frequent misinterpretation was overestimation of tumor size (N=13, 43.3%). Locoregional vascular invasion of veins was suspected by EUS in 13 patients (43.3%) but surgical findings and the histological examination were both negative. Node status was correctly assessed in 27 patients (90%) but nodal involvement was found on the histological specimen in only 3 patients. CONCLUSION Preoperative EUS after neoadjuvant CRT for PDA does not enable reliable definitive selection of patients for surgery, probably due to radiation-induced pancreatic changes.

Abstract
Pancreatic duct carcinoma remains a common disease with a poor prognosis. More than 30,000 Americans will die of the disease in 2004, making it the fourth leading cause of cancer death. Despite significant advances in the treatment of many other human tumors, the 5-year survival rate for persons diagnosed with pancreatic cancer has not changed in decades and remains <5%. This is due both to the inherently aggressive biology of the disease and to its late diagnosis in most cases. Surgical resection of localized disease remains the only hope for cure of pancreatic cancer. Over the past 2 decades, significant advances in diagnostic imaging, staging, surgical technique, and perioperative care have led to marked improvement in the surgical management of pancreatic cancer patients. Operative mortality rates for pancreaticoduodenectomy are now <5% at major centers, and the average length of hospital stay has been reduced to <2 weeks. Improvements in patient outcome after pancreatic cancer surgery have made possible, for the first time, the design and conduct of large adjuvant therapy studies in pancreatic cancer. Such clinical trials are critical for improving outcomes for pancreatic cancer patients.

Abstract
BACKGROUND Computed tomography (CT) is insensitive to small metastatic deposits in patients with pancreatic cancer. This study aimed to evaluate additional staging information obtained by laparoscopy in the subset of patients with locally extending pancreatic cancer but no evidence of distant disease using computed tomography. METHODS Between April 2000 and February 2004, 74 patients with locally unresectable pancreatic cancer and no evidence of metastasis detected by high-quality pancreas protocol computed tomography underwent outpatient staging laparoscopy and peritoneal lavage cytology. RESULTS Occult tumor was found during staging laparoscopy in 25 of the 74 patients (34%). The results were positive for peritoneal lavage cytology in 27% (20/74), for liver lesions in 16% (12/74), and for peritoneal implants in 7% (5/74) of the patients. Body and tail tumors were twice as likely as pancreatic head tumors to have unsuspected metastasis (53% vs 28%). CONCLUSIONS Even the best computed tomography scan is not adequate for accurate staging of locally extended pancreatic cancer because occult distant disease will be found in half of the patients with left-sided disease and one-fourth of those with right-sided pancreatic cancer.

Abstract
BACKGROUND Neoadjuvant (preoperative) chemoradiotherapy (CRT) for pancreatic cancer offers theoretical advantages over the standard approach of surgery followed by adjuvant CRT. We hypothesized that histological responses to CRT would be significant prognostic factors in patients undergoing neoadjuvant CRT followed by resection. METHODS Since 1994, 193 patients with biopsy-proven pancreatic adenocarcinoma have completed neoadjuvant CRT, and 70 patients have undergone resection. Specimens were retrospectively examined by an individual pathologist for histological responses (tumor necrosis, tumor fibrosis, and residual tumor load) and immunohistochemical staining for p53 and epidermal growth factor receptor. Factors influencing overall survival were analyzed with the Kaplan-Meier (univariate) and Cox proportional hazards (multivariate) methods. RESULTS The estimated overall survival (median +/- SE) in the entire group of patients undergoing resection was 23 +/- 4.2 months, with an estimated 3-year survival of 37% +/- 6.6% and a median follow-up of 28 months. Complete histological responses occurred in 6% of patients. Overexpression of p53 was more common in patients with large residual tumor loads. Tumor necrosis was an independent negative prognostic factor, as were positive lymph nodes, a large residual tumor load, and poor tumor differentiation. CONCLUSIONS Histological response to neoadjuvant CRT--as measured by residual tumor load--may be useful as a surrogate marker for treatment efficacy. Characterization of the tumor cells that survive neoadjuvant CRT may help us to identify new or more appropriate targets for systemic therapy.

Abstract
The length and quality of life of patients with localized pancreatic cancer will be maximized by accurate preoperative assessment of resectability, a standardized technique of tumor resection, and the routine use of protocol-based adjuvant or neoadjuvant therapy. Continued efforts to enroll patients with localized and advanced pancreatic cancer into well-designed clinical trials should remain a high priority for oncologists across all disciplines. At present, preoperative therapy remains investigational but has a sound clinical basis and remains a reasonable alternative to up front surgery. Future clinical trials for resectable pancreatic cancer will lead to progress only if the principles of multidisciplinary cancer care and quality assurance are incorporated into their design and conduct.

Abstract
PURPOSE The benefits provided by preoperative chemoradiotherapy (CRT) in pancreatic ductular adenocarcinoma (PDA) are still controversial. However, in most reports from referral centers, improvement in local control and survival appears to be provided in selected patients. The aim of this retrospective study was to analyze the radiation-induced pathologic effects of preoperative CRT in patients with resectable PDA and determine the precise long-term outcome of the responding patients. METHODS AND MATERIALS Between November 1996 and October 2003, 61 patients underwent preoperative CRT for resectable PDA. The tumor location was the pancreatic head in 49 patients and pancreatic body in 12 patients. Of the 61 patients, 21 (34.5%) did not undergo surgery because of disease progression and 40 (65.5%) underwent pancreatic resection, including pancreaticoduodenectomy in 32 (80%) and distal pancreatectomy in 8 (20%). RESULTS A major pathologic response was noted in 9 patients, including three complete responses, and was found only in patients with tumor of the pancreatic head. The local control rate was similar in patients with and without a major pathologic response. Survival in patients with a major response was significantly greater than in those without a response or with a minor response. CONCLUSION Major tumor downstaging can be provided by preoperative CRT in patients with resectable cephalic PDA. Survival appears to be significantly improved in selected patients.

Abstract
The advantages of neoadjuvant (preoperative) chemoradiation therapy for pancreatic cancer include the assurance that all resected patients receive multimodality therapy; the opportunity for patients with occult metastatic disease to manifest themselves; and the potential to improve resectability. Since 1994, Duke University Medical Center has treated over 180 patients with localized pancreatic cancer using neoadjuvant 5-fluorouracil (5FU)-based chemoradiation therapy (CRT). Approximately 20% of patients demonstrate distant disease progression during CRT and avoid the morbidity of laparotomy. Almost 20% of locally advanced tumors on initial-staging CT can be resected following CRT. Patients who have successfully undergone resection have experienced favorable survival with an estimated 5-year survival rate of 36%. This article reviews the authors' experience and the lessons learned from it.

Abstract
Gemcitabine sensitizes tumor cells to radiation and cisplatin and thereby enhances the cytotoxic effect of gemcitabine. Here we report the efficacy and toxicity of concurrent chemoradiation with gemcitabine and cisplatin in the treatment of patients with locally advanced, unresectable pancreatic cancer. A total of 47 patients (29 men, 18 women; median age 61 years) with histologically proven advanced pancreatic carcinoma were included in the study. They underwent chemotherapy with gemcitabine 300 mg/m2 and cisplatin 30 mg/m2 on days 1, 8, 22, and 29; concurrent radiation (45-50 Gy) was applied to the tumor and regional lymph nodes (1.8-2.0 Gy/fraction 5 days per week). Subsequent to chemoradiotherapy, treatment was continued with more two cycles of gemcitabine (1000 mg/m2) and cisplatin (50 mg/m2) applied on days 1 and 15 of a 4-week cycle. After completion of chemoradiotherapy, 9 patients (19.1%) achieved a complete response and 23 patients (48.9%) a partial response, for an overall response rate of 68%. The lesions were considered resectable in 27 patients, and 25 of the 27 patients underwent laparotomy. The other 20 patients underwent a definitive pancreatic resection. Altogether, 13 patients had negative surgical margins. With a median follow-up of 25.7 months (range 12.7-38.7 months) after completion of chemoradiation, distant metastasis had occurred in 23 patients and local recurrence in only 4 of 44 patients (8.5%). the median progression-free survival was 7.8 months (range 6.2-9.4 months). The median survival amounted to 10.7 months (range 8.4-13.0 months) for all patients, whereas it was prolonged to 24.2 months (range 6.8-41.7 months) for those undergoing R0 resection. The main toxicities associated with chemoradiation included grade 3/4 leukopenia (68% of patients) and thrombocytopenia (61%). Episodes of cholangitis were observed in 11 patients. We concluded that gemcitabine and cisplatin can safely be combined with external beam radiation. This preoperative treatment approach is highly effective and appears to improve survival in patients whose tumors are rendered completely resectable.

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
Adenocarcinoma of the pancreas is the fourth leading cause of cancer death in men and women in the United States. It affects nearly as many people each year as does the human immunodeficiency virus and has a much worse outcome. This article reviews the progress in treatment of this disease since 1975, outlines the current clinical and research challenges in the field, and suggests a plan of action to address these challenges. The world literature in the field since 1975 was reviewed, and the pancreatic cancer Progress Report Group of the National Cancer Institute (NCI) is reviewed and presented. Some progress has been made in understanding and treating pancreatic cancer since 1975. Much remains to be done. The lack of progress in the field can largely be attributed to the lack of importance and subsequent lack of research dollars attributed to it by the NCI. The NCI is addressing this issue by proposing to fund Specialized programs of research excellence grants in pancreatic cancer. In addition, other mechanisms exist within the NCI to allow for additional funding of pancreatic cancer. Using the tremendous progress made in the field of human immunodeficiency virus research as an example, it is hoped that similar improvements can be made in the field of pancreatic cancer if substantial and sustained efforts are made.

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
BACKGROUND Studies have suggested an increased risk of peritoneal seeding in patients with pancreatic cancer diagnosed by percutaneous FNA. EUS-FNA is an alternate method of diagnosis. The aim of this study was to compare the frequency of peritoneal carcinomatosis as a treatment failure pattern in patients with pancreatic cancer diagnosed by EUS-FNA vs. percutaneous FNA. METHODS Retrospective review of patients with non-metastatic pancreatic cancer identified 46 patients in whom the diagnosis was made by EUS-FNA and 43 with the diagnosis established by percutaneous FNA. All had neoadjuvant chemoradiation. Patients underwent restaging CT after completion of therapy, followed by attempted surgical resection if there was no evidence of disease progression. RESULTS There were no significant differences in tumor characteristics between the two study groups. In the EUS-FNA group, one patient had developed peritoneal carcinomatosis compared with 7 in the percutaneous FNA group (2.2% vs. 16.3%; p<0.025). No patient with a potentially resectable tumor in the EUS-FNA group had developed peritoneal carcinomatosis. CONCLUSIONS Peritoneal carcinomatosis may occur more frequently in patients who undergo percutaneous FNA compared with those who have EUS-FNA for the diagnosis of pancreatic cancer. A concern for peritoneal seeding of pancreatic cancer via percutaneous FNA is warranted. EUS-guided FNA is recommended as the method of choice for diagnosis in patients with potentially resectable pancreatic cancer.

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
BACKGROUND Resected pancreatic cancer has a high risk of recurrence and mortality despite the the use of chemoradiotherapy. Because pancreatic cancers express tumor antigens such as carcinoembryonic antigen (CEA), it may be possible to immunize patients to induce tumor antigen-specific immune responses. We hypothesize that high-frequency tumor antigen-specific immune responses will reduce recurrence and increase survival. Autologous dendritic cells (DCs) loaded with tumor antigens are particularly potent at inducing tumor antigen-specific immune responses. METHODS Three patients with resected pancreatic adenocarcinoma following neoadjuvant chemoradiotherapy received autologous, monocyte-derived DCs loaded with the mRNA encoding CEA monthly for 6 mo. RESULTS It was feasible to generate an adequate number of DC from these patients and to cryopreserve them for repeated use. The DC demonstrated the typical immature phenotype. The immunizations were well-tolerated without evidence of adverse events. All three developed injection site reactivity. All three are alive without evidence of disease at more than 2 1/2 yr from the original diagnosis. CONCLUSION The postoperative period following neoadjuvant chemoradiotherapy and pancreaticoduodenectomy for pancreatic cancer is an ideal environment to test novel immune-based therapies. DC-based immunotherapy in this setting is safe and feasible and may lead to prolonged survival.

Abstract
PURPOSE To assess the toxicity and efficacy of preoperative chemoradiation in pancreatic cancer. METHODS AND MATERIALS Between November 1996 and December 2001, 32 patients with biopsy-proven pancreatic adenocarcinoma (28 head; 4 body) were treated by chemoradiation consisting of either split-course therapy (two courses of 15 Gy separated by a 2-week break, n = 10) or standard-fractionation therapy (45 Gy during 5 weeks, n = 22). Concurrent chemotherapy included continuous infusion of 5-fluorouracil and a cisplatin bolus. Pancreatic resection was scheduled for 4-6 weeks after completion of chemoradiation treatment. RESULTS All 32 patients completed the chemoradiation protocol. Only 2 cases of Grade 3 toxicity (weight loss, vomiting) and one fatal Grade 4 infection occurred. Of the 32 patients, 19 underwent curative resection. Two patients had a complete pathologic response. One patient died 36 months after diagnosis of late treatment-related toxicity (acute superior mesenteric artery thrombosis) with no evidence of disease. The 2-year overall survival rate for the entire group and the resected patients was 37.3% (95% confidence interval 18.2-56.4%) and 59.3% (95% confidence interval 34.1-84.9%), respectively. CONCLUSION Preoperative chemoradiation with 5-fluorouracil and cisplatin is feasible and promising.

Abstract
BACKGROUND This study examined the effect that 18-fluorodeoxyglucose positron emission tomography ((18)FDG-PET) imaging had on the clinical management of patients with suspected periampullary malignancy. METHODS Fifty-four patients with suspected pancreatic neoplasms underwent both whole-body (18)FDG-PET and abdominal computed tomography (CT). Malignant or benign disease was confirmed pathologically in 47 patients. RESULTS Of the 41 patients with malignancy, (18)FDG-PET failed to identify the primary tumor in 5 patients. (18)FDG-PET demonstrated increased uptake suggesting primary malignancy in 37 patients. Malignant pathology was confirmed in 36 cases. (18)FDG-PET identified malignant locoregional lymph node metastases in six of ten patients. All nodes identified before surgery by (18)FDG-PET were also seen on preoperative CT. Six patients who were thought to have resectable disease by CT were found to have distant metastasis at laparotomy. (18)FDG-PET did not detect metastasis in any of these cases. Before surgery, (18)FDG-PET identified distant metastases that were not detected by CT in one patient. CONCLUSIONS Despite high sensitivity and specificity in diagnosing periampullary malignancy, (18)FDG-PET did not change clinical management in the vast majority of patients previously evaluated by CT. In addition, (18)FDG-PET missed >10% of periampullary malignancies and did not provide the anatomical detail necessary to define unresectabilty.
