Title: Phase II study of hypofractionated radio-chemotherapy with gemcitabine plus oxaliplatin for unresectable nonmetastatic locally advanced pancreatic cancer. Protocol code: IRST157.01 Phase: II Study Design: monocentric, prospective, open-label not randomized trial. Description of Study Treatment: radio-chemotherapy schedule - GEMOX: Gemcitabine (GEM) 1000 mg/m2, day 1, and Oxaliplatin (OX) 100 mg/m2, day 2, every 2 weeks for 4 cycles. - Hypofractionated radiotherapy (35 Gy in 7 fractions in 9 consecutive days, one session per day excluding Saturday and Sunday) administered 15 days after the 4th chemotherapy cycle. - Further 4 cycles of GEMOX, starting 7-15 days after the end of the radiotherapy. Objectives: Step A: primary objective = to evaluate the safety of radiotherapy treatment. Secondary objective = the control of IM (internal margin) intra-fraction. Step B: primary objective = to evaluate the proportion of the resectable patients after radio-chemotherapy. Secondary objectives = overall Response Rate (ORR); safety profile of combinated treatment;overall survival (OS); local progression free survival (LPFS) and progression free survival (PFS). Statistical Considerations: Step A: Assuming that the probability to observe a toxicity involving the radiotherapy treatment discontinuation with the new treatment is less than 20%, 11 patients are to be evaluated for toxicity. If no toxicity involving the radiotherapy treatment discontinuation will be observed in 11 patients, the treatment can be considered safe with a probability > 90%. If 1 toxicity involving the radiotherapy treatment discontinuation will be observed, 7 more patients needs to be recruited. If no further toxicity involving the radiotherapy treatment discontinuation occurs, the treatment could be considered safe with a probability ≥ 90%. If 2 or more toxicity involving the radiotherapy treatment discontinuation on 11 patients or 2 or more toxicity involving the radiotherapy treatment discontinuation on 18 patients will be observed, the study will be stopped because not safe and another kind of radiotherapy schedule must be designed. Step B: If the radiotherapy treatment will be considered no toxic, the study will continue in Step B : the goal of this phase II study is to increase the proportion of resectable patients of at least 15% with the new radio-chemotherapeutic treatment. By using the single-stage design (Gehan EA, J Chron Dis 1961) a total of 40 patients is required to be recruited in 2 years, and a further one-year period of follow-up is requested. If at least 7 patients out of 40 enrolled will be resectable, the hypothesis that the proportion of resectable patients will be less or equal to P1 (P1=the proportion of resectable patients with the new radio-chemotherapeutic treatment) will be refused and the treatment could be considered active.
1. Background - Advanced guidewires with a U-shaped tip could effectively cross the long or multi-occlusive segment smoothly and go into the distal outflow vessel. - The guidewire looping technique is a safe and effective method for the recanalization of the occluded lesions in infrapopliteal vessels. 2. Objective - To compare the performance a loop-tipped guidewire with a straight-tipped guidewire in achieving successful deep biliary cannulation. 3. Design - Prospective randomized trial. 4. Setting: - Tertiary-care medical center 5. Patients - This study will involve 192 patients with biliary diseases which require endoscopic retrograde cholangiopancreatography. 6. Intervention - Cannulation of bile duct by using a loop-tipped guidewire or a straight-tipped guidewire 7. Main outcome measurements - Compare the cannulation success rate, the duration of the cannulation, immediate and late complications.
This phase Ⅱ study was designed to evaluate the efficacy and safety of mFOLFIRINOX as first-line treatment for metastatic pancreatic cancer in China.
Recently up-coming drug, etomidate which is a modulator of GABA(gamma-Aminobutyric acid)-A receptor has been known that it maintains the appropriate sedative levels and affects little effects on respiratory system. The investigators are now trying to investigate that etomidate with meperidine combination regimen is superior to the midazolam with meperidine more effective and less harm on sedation during the ERCP procedure.
The overall aim of this study is to investigate a novel "dual instance" planning method to make use of the respiratory motion to improve pancreatic radiation therapy (RT) treatment planning. Specific Aim 1: Acquire patient abdominal MRI and CT at both deep inspiration (INSP) and expiration (EXP) positions and characterize the changes in geometric relationships between the INSP and EXP instances for tumor and normal tissues including stomach, duodenum and bowel. We hypothesize that INSP and EXP MRI and CT characterization will allow identification of patients who may benefit from the dual instance planning method. Specific Aim 2: Develop, investigate and evaluate plans based on free breathing, single instance breath hold, and the novel dual instance anatomical information. We hypothesize that use of the dual instance method will lead to improved plans, demonstrated by the ability to increase dose to the target, while maintaining the clinically-accepted normal tissue dose constraints.
Pancreatic cancer has an extremely poor prognosis with a 5-year survival rate of less than 5%. About 25% of patients have the opportunity for radically surgical resection when diagnosis. However, the recurrence rate is up to 85% within 2 years. Data from clinical trials indicated that gemcitabine-based adjuvant chemotherapy reduced recurrence and enhanced overall survival for patients who have undergone surgery to remove their tumor. Nab-paclitaxel could enhance the intratumoral concentration of gemcitabine; recent studies showed that nab-paclitaxel plus gemcitabine significantly improved progression-free survival and overall survival of metastatic pancreatic cancer patients. The present study is intended to investigate the activity and safety of the combination of gemcitabine and nab-paclitaxel as adjuvant chemotherapy in treating patients with pancreatic cancer after curative resection.
The investigators preliminary data suggests that FOLFOX-A may have equal or superior activity as compared to FOLFIRINOX and appears to be better tolerated. Therefore, FOLFOX-A may be a better regimen in the adjuvant setting for patients with resected pancreatic cancer. This protocol will obtain preliminary data on safety and disease-free and overall survival following administration of FOLFOX-A for patients with resected pancreatic cancer.

This study is a research initiative established to explore the use of magnetic resonance imaging (MRI) as a tool for detecting organ motion as it pertains to planning radiation therapy.
