For many years, the treatment of jaundice due to head pancreatic adenocarcinoma is based on the endoscopic biliary stent. This technique has been shown to be preferable to a surgical shunt. Recently, adjuvant chemotherapy with FOLFIRINOX regimen (clinical trial) has revolutionized the treatment of metastatic pancreatic adenocarcinoma increasing overall survival in a major way. This design will also be developed in patients with neoadjuvant tumor called "borderline" (the limit of the resectability). However, several conditions (protocol) are required to consider the implementation of this design : age ≤ 75 years, PS 0 or 1, good hematological parameters and bilirubin ≤ 1.5 times the ULN. In addition, a randomized study showed that preoperative biliary stent treatment, despite a success rate of 94%, is associated with more complications than surgery fast (related gesture bladder). It would be interesting to analyze, prospectively, the fate of a series of patients with cancer of the pancreatic head with compression of the lower part of the bile duct, PS 0 or 1 and for which the only limit to FOLFIRINOX design is jaundice or high risk of jaundice.
We will be conducting a Phase II study investigating PEGPH20 in combination with gemcitabine and nab-paclitaxel in patients with borderline resectable pancreatic ductal adenocarcinoma (PDAC) at the Helen Diller Family Comprehensive Cancer Center at University of California, San Francisco (UCSF). There are multiple definitions of borderline resectable PDAC including the MD Anderson definition and the criteria developed during the Consensus Conference sponsored by the American Hepato-Pancreato-Biliary Association, Society of Surgical Oncology, and Society for Surgery of the Alimentary Tract. Borderline resectable PDAC cases will be identified per the definition developed in the currently running inter-group pilot trial for borderline resectable pancreatic cancer (NCT01821612). Per this trial, borderline resectable PDAC is defined as "presence of any one or more of the following on CT: - An interface between the primary tumor and the superior mesenteric vein or portal vein (SMV-PV) measuring ≥ 180° of the circumference of the vessel wall - Short-segment occlusion of the SMV-PV with normal vein above and below the level of obstruction that is amenable to resection and venous reconstruction - Short segment interface (of any degree) between tumor and hepatic artery with normal artery proximal and distal to the interface that is amenable to resection and reconstruction. - An interface between the tumor, and Superior mesenteric artery (SMA) measuring < 180º of the circumference of the vessel wall. This trial will be conducted in two parts. In Part I, pre-treatment endoscopic ultrasound (EUS)-guided core biopsies of the pancreatic tumor, CA 19-9 levels and functional MRIs including Dynamic contrast-enhanced (DCE)-MRI and Diffusion-weighted magnetic resonance imaging (DWI-MRI) will be obtained for the first fifteen patients enrolled. After a 1-week run-in period with PEGPH20 on days 1 and 4, patients will have repeat EUS-guided core biopsies, functional MRI, CA 19-9 level and baseline CT chest, abdomen and pelvis. Subsequently, patients will be started on treatment with PEGPH20, gemcitabine and nab-paclitaxel given weekly for 3 weeks, every 28 days. To evaluate the disease response to treatment, CA 19-9 levels will be checked monthly and restaging CT chest, abdomen and pelvis will be obtained every 8 weeks. If there is disease progression at any point in the study, patients will be taken off of study and alternative treatments will be offered. At the completion of 4 cycles of therapy, restaging CT scans will be obtained to determine resectability. If the patients are found to have resectable disease, an additional functional MRI will be obtained to evaluate the PDAC stroma. If the patients are able to have successful surgeries, tissue analyses will be performed on the resected pancreatic tumor. These patients will then proceed to get 2 cycles of adjuvant chemotherapy with gemcitabine and nab-paclitaxel. If the patients are deemed to be surgical candidates but are found to have unresectable disease in the operating room, an intraoperative core biopsy of the pancreatic tumor will be obtained for tissue analyses. At the time of initiation of therapy with PEGPH20, patients will be started on prophylactic dose of enoxaparin 1 mg/kg subcutaneous daily. This will be continued throughout the study participation. In Part II, an additional 21 patients will be enrolled, and will begin neoadjuvant therapy with PEGPH20, gemcitabine and nab-paclitaxel without the 1 week run-in of PEGPH20-only or the pre- and post-run-in EUS-guided biopsies.
This is a non-randomized pauci-centre, open-label phase II study. The treatment will consist in a chemotherapy by FOLFOX and nab-paclitaxel following modalities determined in the Brown University Phase I study. In neoadjuvant setting : 3 months of treatment Main criteria of Withdraw of the treatment: in case of tumor progression, non acceptable toxicity, or patient decision. Post-operative treatment (for 6 additional cycles) is recommended, but will depend on the result of the neo-adjuvant treatment and the ability of patients to receive adjuvant chemotherapy based on tolerance of neo-adjuvant treatment and general post-operative condition (i.e. adjuvant treatment if no progression during neo-adjuvant chemotherapy, less than 80% of residual viable tumor compared to initial tumor volume, acceptable tolerance and post-operative PS 0 - 2). Adjuvant treatment must be initiated within 8 weeks post-operatively.
This randomized phase II trial studies how well fludeoxyglucose F-18 (FDG)/positron emission tomography (PET) directed treatment improves response in patients with stomach or gastroesophageal junction cancer that has not spread past the stomach and is not responding to the usual treatment. PET scans are a different way to take pictures of cancer and can be used to look at how much energy (such as glucose) is being used by the cancer. Using PET scans early to monitor the success of treatment may allow doctors to measure response and change treatment accordingly.
A phase II, randomized study of placebo versus metformin in association to chemotherapy with capecitabine and radiation in the neoadjuvant treatment of locally advanced (T3-4N0M0 or TxN1-2M0) rectal carcinomas.
This phase I trial studies the side effects and best dose of multitargeted tyrosine kinase inhibitor PLX3397 (PLX3397) when given together with radiation therapy and antihormone therapy in treating patients with prostate cancer that is at intermediate or high risk of spreading. Multitargeted tyrosine kinase inhibitor PLX3397 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth, and may also help the radiation therapy work better. Radiation therapy uses high-energy x-rays to kill tumor cells. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as leuprolide acetate, goserelin acetate, or degarelix, may lessen the amount of androgens made by the body. Giving multitargeted tyrosine kinase inhibitor PLX3397 with radiation therapy and antihormone therapy may be a better treatment for prostate cancer.
This research study is evaluating whether a standard prostate MRI examination can improve radiation therapy planning for prostate cancer.
This phase I/II trial studies the side effects and best dose of stereotactic body radiation therapy while using intensity-modulated radiation therapy (IMRT) planning to help avoid radiation to normal tissue in patients with prostate cancer. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using small, high doses of radiation over several days and may cause less damage to normal tissue. This treatment schedule allows for a higher dose of radiation to be administered over a shorter overall treatment period in comparison to standard radiation therapy.
The primary objective of this study is to evaluate the safety of single agent idelalisib and to evaluate safety and define the maximum tolerated dose (MTD) of idelalisib in combination with chemotherapy in adults with metastatic pancreatic ductal adenocarcinoma.
