Filter by:A minority of patients with colorectal liver metastases and hepatobiliary cancer (primary liver cancer) are candidates for surgery, but there are no curative treatment options for these patients. Their median survival time is 3 to 12 months. Stereotactic radiation (SRT) (highly conformal radiotherapy (CRT)) is a treatment option for these patients with unresectable liver cancer, now possible due to improvements in our ability to localize and immobilize liver tumors and an improved understanding of the partial liver volume tolerance to radiation. SRT should permit liver tumors to be treated to tumorcidal doses while sparing the uninvolved liver, decreasing the risk of treatment related normal tissue toxicity. With such conformal radiation, it is possible to deliver radiation in fewer fractions than traditionally required, which should be more convenient for patients. In this study, CRT will be delivered during shallow breathing or breath hold to minimize organ motion due to breathing, decreasing the volume of normal liver that must be irradiated.
Studies have provided evidence that residual microscopic malignant cells in autologous bone marrow or blood stem cell grafts can contribute to posttransplant relapse. Researchers are currently exploring different methods in an attempt to purify or "purge" the stem cell product to minimize the risk of tumor contamination. The CD133+ antigen is a protein contained on or "expressed" on numerous cells in the human body including specific hematopoietic progenitor (blood forming) cells. However, this antigen is not expressed on certain cancer cells including neuroblastoma. A technique using the investigational CliniMACS cell sorting device has been developed in an effort to filter out only those stem cells that express this CD133+ antigen in order to infuse a hematopoietic stem cell product with no tumor contamination potential. The primary objective of this study is to establish safety of treating patients with a high dose chemotherapy regimen of Busulfan and Melphalan followed by autologous CD133+ hematopoietic stem cell support. Transplants recipients are expected to achieve engraftment as defined by an absolute neutrophil count of greater than or equal to 500/mm3 for three consecutive days by day 42-post infusion. Thus, safety of the treatment plan will be evaluated in terms of failure to engraft by this specific time period.
This study is an open-label study. It has two stages. Stage 1 is a dose escalation phase of the study to determine and evaluate the safety and tolerability of repeated treatments with a genetically engineered herpes simplex virus NV1020 administered locoregionally to the liver. Stage 2 is to evaluate the dose found in Stage 1 to be "optimally tolerated". Stage 2 is to assess the efficacy of the optimally tolerated dose of NV1020 by itself and in combination with second-line chemotherapy. Assignment to Stage 1 or Stage 2 of the study is determined by when the patient enters the study.
MEK is a critical member of the MAPK pathway involved in growth and survival of cancer cells. PD-325901 is a new drug designed to block this pathway and kill cancer cells. The purpose of this study is to study the effectiveness of PD-325901 in patients with colon cancer, breast cancer, and melanoma. PD-325901 will be given by mouth as a pill twice a day, CT scans will be done and biopsies will be taken of a tumor before and once during treatment to measure the effects of the drug. Blood samples will be taken to measure the amount of drug in the blood.
AG-024322 may work in cancer by stopping cancer cells from multiplying. AG-024322 is and intravenous drug from a new class of drugs call cyclin-dependent kinase (CDK inhibitors). This research study is the first time that AG-024322 will be given to people.
To evaluate the survival benefit of adjuvant chemotherapy after curative resection with D2 or greater lymph node dissection in T3-4 gastric cancer patients.
The aim of the study is to obtain information on FLT used in a PET-scan as a marker for the proliferation of colorectal liver metastases, so that the risk of recurrence can be identified in a noninvasive way, concerning patients with resectable colorectal liver metastases. The hypothesis of this study is that a higher uptake of FLT in the liver metastases has a good correlation with the proliferation rate of the metastases. This rate is related to the risk of recurrence.
To determine Carboplatin's optimal exposures(optimal AUCs)and parameters they depend on.
The median survival at progression after first-line chemotherapy for metastatic gastric cancer is about 2.5 months. There are no data which a possible benefit of second line therapy. for this reason a trial which investigates a possible benefit or chemotherapy compared to best supportive care as second line treatment is urgently necessary. Irinotecan shows response rates of 20% in the first line therapy with high rates od disease stabilization. There are few trials investigating irinotecan in the second line setting. Response rates of 20% are reported in tis setting. Irinotecan is supplied without costs from the company Pfizer.
To see if Disease Free Survival (DFS) is improved when complete surgical resection of liver metastases (R0) is followed by chemotherapy with CPT-11 and 5-FU/FA as FOLFIRI regimen, compared to 5-FU/FA alone.
