Abstract
BACKGROUND Through a phase I study with a fixed radiation dose of 54 Gy and escalating doses of weekly gemcitabine, we established a recommended dose of gemcitabine at 250 mg/m in combination with radiation therapy for patients with unresectable pancreatic cancer. OBJECTIVE The purpose of this phase-II study was to evaluate the safety and efficacy of the regimen which was established in the phase I study. METHODS In all patients with unresectable stage III and limited stage IV pancreatic cancer with no distant metastasis except for para-aortic lymph node involvement at a level as low as the left renal vein, a total dose of 54 Gy was delivered in 30 fractions of 1.8 Gy/d. Gemcitabine was given weekly at a dose of 250 mg/m. RESULTS Between December 2002 and March 2006, 22 patients were enrolled in this study and one withdrew after enrollment. Twenty of 21 patients (95%) completed the protocol therapy. Radiologic partial response was observed in 6 and stable disease was noted in 15. Normalization of the tumor marker (CA19-9) occurred in 61% of patients. The 1-year survival rate was 74% and the median survival time was 16.6 months. The major toxicity was leucopenia; grade 3 in 14 (67%), anorexia grade 3 in 2 (9.5%), and grade 3 gastric ulcer in 2 (10%) in National Cancer Institute's Common Terminology Criteria for Adverse Events version 3.0 (NCI-CTCAE v3.0). Neither grade 4 nor 5 was recognized. CONCLUSION Treatment with gemcitabine combined with radiation therapy according to the present schedule is well tolerated and can provide prolonged survival in patients with localized, unresectable pancreatic cancer.

Abstract
AIMS Patients with locally advanced pancreatic cancer (LAPC) are most commonly managed with chemotherapy or concurrent chemoradiotherapy (CRT), which may or may not include non-involved regional lymph nodes in the clinical target volume. We present our results of CRT for LAPC using capecitabine and delivering radiotherapy to a limited radiation field that excluded non-involved regional lymph nodes from the clinical target volume. MATERIALS AND METHODS Thirty patients were studied. Patients received 50.4 Gy external beam radiotherapy in 28 fractions, delivered to a planning target volume expanded from the primary tumour and involved nodes only. Capecitabine (500-600 mg/m2) was given twice daily continuously during radiotherapy. Toxicity and efficacy data were prospectively collected. RESULTS Nausea, vomiting and tumour pain were the most common grade 2 toxicities. One patient developed grade 3 nausea. The median time to progression was 8.8 months, with 20% remaining progression free at 1 year. The median overall survival was 9.7 months with a 1 year survival of 30%. Of 21 patients with imaged progression, 13 (62%) progressed systemically, three (14%) had local progression, two (10%) had locoregional progression and three (14%) progressed with both local/locoregional and systemic disease. CONCLUSION CRT using capecitabine and limited field radiotherapy is a well-tolerated, relatively efficacious treatment for LAPC. The low toxicity and low regional progression rates support the use of limited field radiotherapy, allowing evaluation of this regimen with other anti-cancer agents.

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 evaluate local effects and acute toxicities of involved field irradiation with concurrent cisplatin (CDDP) for unresectable pancreatic carcinoma. MATERIALS AND METHODS Thirty-three patients with unresectable pancreatic carcinoma were treated with chemoradiotherapy. Sixteen were Stage IVA; 17 were Stage IVB. The total prescribed dose of radiotherapy was 50 Gy/25 fractions or 50.4 Gy/28 fractions, using a three-dimensionally determined involved-field that included only the primary tumor and clinically enlarged lymph nodes. Twelve patients received a daily i.v. infusion of CDDP; 21 patients received a combination of CDDP and 5-fluorouracil either i.v. or through the proper hepatic artery. RESULTS Twenty-seven (82%) patients completed planned chemoradiotherapy. Nausea was the most frequent complaint. No patient experienced Grade 4 toxicities. More than half achieved pain relief. As for the primary site, only 4 patients (12%) achieved a partial response at 4 weeks; however, 3 additional patients attained >50% tumor reduction thereafter. The most frequent site of disease progression was the liver, and only 3 patients developed local progression alone. No regional lymph nodal progression outside the treatment field was seen. Median survival time and survival at 1 year were 7.1 months and 27%, respectively, for the entire group. Difference in overall survival between patients with and without distant metastases was significant (p = 0.01). CONCLUSIONS Involved-field irradiation with concurrent daily CDDP was well tolerated without compromising locoregional effects.

Abstract
OBJECTIVES Primary chemoradiotherapy for locally advanced pancreatic cancer (LAPC) may improve local control, curative resection rate and long-term survival. We performed a phase II study to evaluate toxicity and activity of primary radiation therapy and concurrent chemotherapy with gemcitabine (GEM) twice weekly in patients (pts) with LAPC. METHODS From 6/1999 to 6/2003, 23 LAPC pts received GEM 100 mg/m2 twice weekly in the first 15 pts and 50 mg/m2 in the last 8 pts, concurrently with radiotherapy (1.8 Gy/day for a total dose of 45 Gy). RESULTS The treatment was completed in 19/23 pts. Toxicities: G3-4 hematological toxicity occurred in 35 and 4% respectively; G3 nausea and vomiting and gastrointestinal toxicity in 30%. Clinical benefit was found in 10/18 pts (55%). Overall response: partial response rate 4/18 (22%); stable disease 13/18 (72%); progressive disease 1/18 (6%). Six pts underwent pancreaticoduodenectomy with extended lymphadenectomy (5/6 pts pT3, 1/6 pts microscopic cancer foci, 1/6 N+, 5/6 negative retroperitoneal margin). MEDIAN SURVIVAL: 14 months for the entire group, 12 months for unresected pts, 20 months for resected pts. CONCLUSIONS The treatment with GEM twice weekly at 50 mg/m2 associated with radiotherapy (45 Gy) is feasible and permits to obtain clinical benefit in a good percentage of pts. Objective response, median survival, and local and systemic control are similar to other studies and need further improvement.

Abstract
OBJECTIVES Chemoradiotherapy, which is one of the standard treatments for locally advanced pancreatic carcinoma, is considered a high-risk procedure in elderly patients. This study investigated the outcome and tolerability of this treatment in elderly patients. METHODS We reviewed our database from November 1993 to March 2003 and retrospectively examined the clinical data of patients with histologically confirmed exocrine pancreatic carcinomas that were nonresectable but confined to the pancreatic region, who were treated with protracted 5-fluorouracil infusion (200 mg/m2/day) and concurrent radiotherapy (50.4 Gy in 28 fractions over 5.5 weeks). We evaluated the outcome of patients > or =70 years and those <70 years. RESULTS There were 19 patients > or =70 and 39 patients <70. On pretreatment evaluation, the elderly patients showed lower serum albumin levels, lower transaminase levels, better ECOG performance status, more frequent body weight loss and less frequent abdominal and/or back pain with the administration of morphine than the younger patients. There were no significant differences in the frequency of severe toxicity. Neither the response rate nor the incidence of treatment discontinuation differed significantly between the two groups. The median survival time was longer in the elderly patients than in the younger patients (11.3 vs. 9.5 months, p = 0.04). CONCLUSIONS With careful patient selection, chemoradiotherapy can be one of the treatment options for locally advanced pancreatic carcinoma in elderly patients.

Abstract
Gemcitabine has been reported to be a potent radiosensitiser in human pancreatic cell lines. This study was conducted to evaluate the efficacy and toxicity of radiotherapy combined with gemcitabine for locally advanced pancreatic cancer. In all, 42 patients with pancreatic cancer that was unresectable but confined to the pancreatic region were treated with external-beam radiation (50.4 Gy in 28 fractions over 5.5 weeks) and weekly gemcitabine (250 mg m−2, 30-min infusion). Maintenance gemcitabine (1000 mg m−2 weekly × 3 every 4 weeks) was initiated 1 month after the completion of the chemoradiotherapy and continued until disease progression or unacceptable toxicity. Of the 42 patients, 38 (90%) completed the scheduled course of chemoradiotherapy. The major toxicity was leucopenia and anorexia. There was one death attributed to duodenal bleeding and sepsis. The median survival time was 9.5 months and the 1-year survival rate was 28%. The median progression-free survival time was 4.4 months. In 35 patients with documented disease progression at the time of analysis, 34 (97%) showed distant metastasis as the cause of the initial disease progression. The chemoradiotherapy used in this study has a moderate activity against locally advanced pancreatic cancer and an acceptable toxicity profile. Future investigations for treatment with more systemic effects are warranted.

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

Abstract
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
PURPOSE To evaluate the effectiveness of small-field radiotherapy in combination with concomitant 5-fluorouracil (5FU) or cisplatin for locally advanced pancreatic carcinoma. MATERIALS AND METHODS From November 1993 to January 1999, 53 patients underwent continuous 5FU infusion at 200mg/m2 (27 patients) or a 30-min cisplatin infusion at 5mg/m2/day (26 patients) just prior to each irradiation. The radiation field was limited to cover the primary and the paraaortic regions at celiac and supramesenteric axis levels. A total dose of 50.4Gy in 28 sessions was given in 5.6 weeks. RESULTS Median and 1-year survival rates were 10.2 months and 35.2%, respectively. Local failure occurred in 19 patients (36%) and liver metastases in 16 patients (30%). All local recurrences occurred only within the radiation field. CONCLUSIONS Median survival rates were comparable to other studies. Because local failure occurred only within the radiation field, the use of relatively small-field radiotherapy may be justified in the treatment of locally advanced pancreatic carcinoma in addition to concurrent administration of either 5FU or cisplatin.

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

Abstract
BACKGROUND Chemoradiotherapy is widely used for patients with locally advanced pancreatic carcinoma. The purpose of this study was to clarify the efficacy and feasibility of chemoradiotherapy with more intensive radiotherapy in these patients, using a combination of intraoperative radiotherapy (IORT), conformal external-beam radiaotherapy (EBRT), and protracted 5-fluorouracil (5-FU). METHODS Thirty patients with unresectable locally advanced pancreatic carcinoma were enrolled in this Phase II study. The treatment consisted of IORT (25 grays [Gy]), followed by EBRT (40 Gy in 20 fractions, 5 times per week), and concurrent protracted 5-FU infusion (200 mg/m(2)), beginning 2-4 weeks after IORT. The authors evaluated the efficacy and adverse effects of this treatment by following up patients for 12.0-28.1 months. Survival from the date of IORT was calculated using the Kaplan-Meier method. RESULTS In 11 of the 30 patients, metastatic spread was detected in the abdominal cavity at laparotomy. The full EBRT dose was administered in 28 of the 30 patients. Of the remaining 2 patients, EBRT was terminated at 8 Gy due to progression of brain metastasis and another patient did not receive EBRT or chemotherapy due to massive ascites after IORT. The overall response rate for primary pancreatic tumor on dynamic computed tomography scan was 23.3% (7 partial responses). Grade 3 or 4 toxicity (according to the National Cancer Institute Common Toxicity Criteria) was observed in 15 of the 28 patients who received the full irradiation dose (53.6%). These included anorexia, nausea, emesis, fatigue, leukopenia, and/or elevation of transaminase levels. There were no directly treatment-related deaths, but 1 patient died of hepatic failure related to late effects of irradiation after 25.6 months. The median survival time of the 30 patients was 7.8 months and the 2-year survival rate was 8.1%. The median survival time of the 19 patients without metastatic spread in the abdominal cavity was 12.9 months and that of the 11 patients with metastatic spread was 5.8 months. CONCLUSIONS The present regimen of chemoradiotherapy is not superior to conventional chemoradiotherapy (EBRT and 5-FU) for patients with locally advanced pancreatic carcinoma.

Abstract
This study investigated the maximum-tolerated dose of gemcitabine based on the frequency of dose-limiting toxicities of weekly gemcitabine treatment with concurrent radiotherapy in patients with locally advanced pancreatic cancer. Fifteen patients with locally advanced pancreatic cancer that was histologically confirmed as adenocarcinoma were enrolled in this phase I trial of weekly gemcitabine (150-350 mg x m(-2)) with concurrent radiotherapy (50.4 Gy in 28 fractions). Gemcitabine was administered weekly as an intravenous 30-min infusion before radiotherapy for 6 weeks. Three of six patients at the dose of 350 mg x m(-2) of gemicitabine demonstrated dose-limiting toxicities involving neutropenia/ leukocytopenia and elevated transaminase, while nine patients at doses of 150 mg x m(-2) and 250 mg x m(-2) did not demonstrate any sign of dose-limiting toxicity. Of all 15 enrolled patients, six patients (40.0%) showed a partial response. More than 50% reduction of serum carbohydrate antigen 19-9 level was observed in 13 (92.9%) of 14 patients who had pretreatment carbohydrate antigen 19-9 levels of 100 U x ml(-1) or greater. The maximum-tolerated dose of weekly gemcitabine with concurrent radiotherapy was 250 mg x m(-2), and this regimen may have substantial antitumour activity for patients with locally advanced pancreatic cancer. A phase II trial of weekly gemcitabine at the dose of 250 mg x m(-2) with concurrent radiation in patients with locally advanced pancreatic cancer is now underway.
