Filter by:Despite significant advances in the understanding of brain tumor biology and genetics as well as improvements in surgical techniques, radiotherapy administration, and chemotherapy methods, many primary brain tumors remain incurable. Most primary brain tumors are highly infiltrative neoplasms, and are therefore unlikely to be cured by local treatments such as surgery, focal radiotherapy, radiosurgery or brachytherapy. A particularly problematic aspect of the management of patients with brain tumors is the eventual development of enhancing lesions on MRI after radiation therapy. The treating physician is then left with the dilemma of what this enhancing lesion may represent (radiation necrosis versus recurrent tumor). The differential diagnosis is between recurrent tumor or radiation necrosis however the amount of each contributing to the enhancing mass on MRI is difficult if not impossible to assess. This particular problem is very common and most patients develop some degree of radiation necrosis after therapy with radiation. Differentiation of necrosis from recurrence is particularly challenging. MRI is typically unable to make this important distinction as there is simply an enhancing mass, the etiology of which could be either necrosis or recurrence. Other imaging methods such as FDG-PET have been used but this technique is also complicated in that the normal brain has FDG uptake and it is often difficult to differentiate recurrence from necrosis. [F-18]FLT may prove to be the most reliable method in making this important differentiation (necrosis versus recurrence) as normal brain and necrotic brain do not have proliferative activity and thus no [F-18]FLT uptake whereas tumor will have proliferative activity and thus [F-18]FLT uptake.
The study is a prospective phase I trial of radiation therapy concurrent with capecitabine and oxaliplatin chemotherapy in the treatment of locally advanced pancreas adenocarcinoma. Eligibility criteria include pathologically confirmed, non-metastatic adenocarcinoma of the pancreas that is surgically unresectable. Patients will undergo radiation therapy (28 treatments of 1.8 Gy for a total of 50.4 Gy) concurrent with capecitabine and oxaliplatin chemotherapy. The primary objective of the study is to determine the maximum tolerated doses of capecitabine and oxaliplatin when delivered concurrently with 50.4 Gy radiation therapy with or without surgery in this patient population. Secondary objectives of the study are to determine the tumor response rate, survival rate, local control rate and the rate of distant metastases following capecitabine, oxaliplatin, and radiation therapy with or without surgery and to determine the rate at which patients with unresectable disease become resectable.
Patients must be currently treated at the Huntsman Cancer Institute or Intermountain Primary Children's Medical Center to be eligible for this study. Although there have been many advances in the assessment and treatment of infections responsible for febrile neutropenia in cancer patients, it still remains a common complication of cancer therapy and accounts for the majority of chemotherapy-associated deaths. This National Cancer Institute (NCI) funded proposal using the R-21 Quick-Trials Exploratory Grant mechanism is to conduct an exploratory/pilot project in a group of patients with persistent febrile neutropenia to provide critical information that will support the concept, and aid in the design, of a larger multi-center clinical trial. The ultimate goal of our interdisciplinary team of oncologists, infectious diseases experts, imagers, and biostatisticians is to conduct a prospective, multi-center trial to establish the utility and cost-effectiveness of PET/CT using the widely available glucose analogue [18F]fluoro-2-deoxy-D-glucose (FDG) in identifying sites of infection in cancer patients with persistent febrile neutropenia without an obvious identifiable source thus improving targeted therapy.
This study is designed as a randomized, prospective study to test the efficacy of imiquimod plus tazarotene in the treatment of LM. Eligible and consented patients will be randomized to one of two treatment groups: 1) topical imiquimod group, or 2) topical imiquimod combined with topical tazarotene group. All patients will undergo a staged surgical excision with rush permanent sections to confirm negative histologic margins. This will be followed by a surgical repair of the defect and long-term follow-up of five years to rule out recurrences. Both groups will have a polygonal excision using 2mm margins per stage.
The study is a prospective phase II trial of radiation therapy concurrent with cisplatin chemotherapy in the treatment of locally advanced or metastatic melanoma in patients who are deemed to require radiation therapy by treating physicians for purposes of local control or palliation. Eligibility criteria include pathologically confirmed melanoma. Patients will undergo radiation therapy (20 treatments of 2.5 Gy for a total of 50 Gy) concurrent with cisplatin chemotherapy.
Meningiomas account for 20% of primary adult brain tumors, occurring at an annual incidence of 6 per 100,000 (Louis, Scheithauer et al. 2000). Complete surgical resection is the treatment of choice but may not possible when the tumor invades critical structures (e.g., skull base, sagittal sinus) (Mirimanoff, Dosoretz et al. 1985; al-Rodhan and Laws 1990; Al-Rodhan and Laws 1991; Newman 1994; De Monte 1995; Levine, Buchanan et al. 1999; Barnett, Suh et al. 2000; Ragel and Jensen 2003). Up to 20% of meningiomas exhibit a more aggressive phenotype that does not respond to standard therapies (Kyritsis 1996). Adjuvant therapies are critical for patients with this subset of meningiomas. Radiation therapy and stereotactic radiosurgery are good adjuvant therapies but are limited by radiation neurotoxicity, tumor size constraints, and injury to adjacent vascular structures or cranial nerves (Goldsmith, Wara et al. 1994; Barnett, Suh et al. 2000; Goldsmith and Larson 2000). Standard chemotherapeutic treatments have been disappointing (Kyritsis 1996). Even drugs like temozolomide that have shown efficacy against malignant brain tumors have failed to inhibit the growth of refractory meningiomas in a phase II study (Chamberlain, Tsao-Wei et al. 2004).
RATIONALE: Providing cognitive-behavioral therapy (CBT) may reduce anxiety and improve quality of life of patients with advanced cancer. PURPOSE: To examine the development and pilot testing of a brief cognitive-behavioral therapy intervention to treat anxiety and improve quality of life in patients with advanced cancer. Hypothesis: Patients with anxiety associated with advanced cancer who receive CBT will report significantly fewer anxiety symptoms compared to those in the comparison condition.
Antigen expression levels in bone marrow from volunteering donors will be analyzed. The results of this analysis will be used to establish a clinical test to identify cancer patients who could qualify to receive an investigational treatment being developed by GlaxoSmithKline.
This is an open-label, three-parallel group pharmacokinetic study. Patients with advanced solid tumors will be assigned to one of three groups to receive I.V. doses of eribulin (E7389). The three groups are: normal hepatic function, mild hepatic impairment (Child-Pugh A) and moderate hepatic impairment (Child-Pugh B) according to the Child-Pugh System for classifying hepatic impairment.
This study will aims to determine the maximum tolerated dose of CGC-11047 when used in individual combinations with gemcitabine, or docetaxel, or bevacizumab, or erlotinib or cisplatin or 5-flurouracil or sunitinib in one of 7 treatment arms. The dose of CGC-11047 will be escalated until the maximum tolerated dose is established.
