Filter by:This study aims to test the hypothesis that insertion of an endorectal balloon into a patient receiving radical prostate radiotherapy by treatment radiographers is feasible without the patient experiencing undue discomfort. In addition this study will test the hypotheses that insertion of the rectal balloon prior to radiotherapy delivery stabilises rectal volume during radiotherapy treatment and minimises organ motion within the pelvis.
Background: - Radiation is a common treatment for prostate cancer. It helps damage tumor cells and causes them to die. Radiation can be effective, but some tumors may be harder to treat with radiation or even with surgery. This happens to a small number of men who have either radiation or surgery for prostate cancer. Most men who have these hard-to-treat tumors do not know if the tumor has recurred only in the prostate or has spread to another area. Also, men whose prostate cancer has recurred only after radiation may have different treatment options. This study will use improved imaging studies to better understand why some men do not respond as well to initial radiation treatments. Objectives: - To use detailed imaging studies to look at the results of local radiation therapy for prostate cancer. Eligibility: - Men at least 18 years of age who are scheduled to have radiation for prostate cancer. - Men at least 18 years of age whose prostate cancer has returned after earlier treatments. Design: - All participants will have a medical history and physical exam. Blood and urine samples will be collected. Imaging studies will be used to evaluate the cancer at the start of the study. - All participants will have an initial full magnetic resonance imaging (MRI) scan of the prostate. Tumor and healthy tissue samples will be collected. - Those whose cancer has recurred after treatment will discuss possible treatment options with the study doctors. - Participants who are scheduled to have radiation will have radiation therapy. This will be given according to the current standard of treatment. - After radiation, participants will have regular follow-up tests and imaging studies. They will have another full MRI scan 6 months after the end of radiation treatment.
This study aims to find out whether the effect of docetaxel chemotherapy may be improved by combining it with another anti-cancer drug called sunitinib, which stops blood vessels from growing (anti-angiogenic agent). Sunitinib is an oral anti-angiogenic drug that has been approved for the treatment of kidney cancer, a rare form of soft tissue tumor called gastrointestinal stromal tumor, and a rare form of cancer in the pancreas called pancreatic neuroendocrine tumor. Sunitinib is usually given continuously at a dose of 37.5mg (3 pills) daily either alone or in combination with chemotherapy. However, there are studies which have shown that the continuous administration of sunitinib may reduce chemotherapy effectiveness. On the other hand, a short course of sunitinib before each chemotherapy cycle may sensitize the tumor to chemotherapy. This treatment strategy will be used in patients with different kinds of cancers with a commonly used chemotherapy drug, docetaxel. Ths study aims to evaluate if intermittent administration of low dose sunitinib before docetaxel chemotherapy can improve the treatment response in cancer patients. Study Hypothesis: Low dose, short course sunitinib at 12.5mg daily orally for 1 week prior to chemotherapy can normalize tumor vasculature and enhance delivery of chemotherapy into the tumor, and improve treatment response and progression-free survival.
The purpose of this study is to assess the safety and effectiveness of natural killer T (NKT) cell-based autologous adoptive immunotherapy in subjects with metastatic, treatment-refractory breast cancer, glioma, hepatocellular carcinoma, squamous cell lung cancer, pancreatic cancer, colon cancer or prostate cancer.
Accelerated Hypofractionation Radiotherapy for prostate cancer of 36.25 Gy delivered in 5 fractions will not be inferior to the standard treatment of 70.2 Gy given in 26 fractions with respect to two-year failure defined as a positive biopsy two years post treatment completion or earlier evidence of biochemical or clinical failure.
Nodal involvement among patients with prostate cancer is known to be a poor prognostic factor. Traditionally, the presence or absence of nodal disease in patients with prostate cancer is ascertained with the use of anatomical imaging methods such as computed tomography (CT) and magnetic resonance imaging (MRI). However, the sensitivities of CT and MRI for the detection of pelvic nodal disease is rather low, with reports placing the value to lie between 50-80%. Positron emission tomography (PET) with the use of carbon-11 or fluorine-18 tagged choline (Choline-PET) is an approach which is known to deliver a high sensitivity for the imaging of prostate cancer disease burden in the primary, nodal and the metastatic areas. The investigators in this prospective trial intend to utilize Choline-PET among all newly diagnosed patients of prostate cancer who are presumed to be non-N1 (absence of nodal disease on conventional imaging) and non-M1 (absence of metastatic disease on conventional imaging).
Quality of life data following SBRT for prostate cancer has been obtained in only a small numbers of patients. A prospective study using validated quality of life questionnaires is needed to determine outcomes after treatment with SBRT. Our study will be the first essential step in developing a better evidence base on the comparative risks and benefits of SBRT treatment with regards to quality of life assessment and outcomes.
This study is investigating measurement of prostate motion during radiotherapy using the implanted gold markers. If motion is greater than 3mm then the beam will be stopped and position corrected (gating).
Background: Prostate cancer (PCa) is the most common cancer for men. When treated early enough it is typically curable. However, common treatments, such as radical prostatectomy and radiation therapy, often result in significant negative outcomes with regard to sexual, psychological and social function. Both men and partners have identified the need for more information and support to address sexual health concerns after treatment. However, very few sexual rehabilitation interventions have been developed and rigorously assessed. Purpose: The investigators propose to develop and pilot test a new program to meet the sexual health needs of men with PCa and their partners using an online, professionally facilitated education/support program. The goals of the program are to improve sexual function, intimacy and mood for men and their partners after treatment for localized PCa. The program will be offered through Cancer Chat Canada, an existing and well-tested Canadian platform for professionally facilitated support group programs. What Participants Can Expect: A total of 24 men and their female partners (48 individuals) will be recruited and assigned to one of two groups. The first group will participate in the program immediately; the second group will be offered the program after a 5-month delay. The decision about which group will start immediately and which later will be made randomly (by chance). Both groups of men and partners will be asked to complete questionnaires three times and, at the end of the program, to provide the researchers feedback about how satisfied they were with the program, the changes they made, things they learned as a result of the program, and suggestions for improving the program. Participants must have access to a computer, an Internet connection and be willing to attend online, chat room meetings each week for 1.5 hours for 6 weeks. Implications: Sexual rehabilitation is a high need for men affected by PCa, but is difficult to access. The investigators hope to improve access to sexual health care through this study.
Surgical removal of tumor at an early stage remains the primary treatment for most cancers. However, there is currently no reliable screening blood test for detection of lung, colon, or breast cancer. The Specific Aims are to: 1) assess the diagnostic accuracy of six FFA metabolites to detect lung and colon cancer in surgical patients; 2)determine the rate and extent to which FFA metabolites decrease over time after surgery for lung and colon cancer; and, 3)determine the positive and negative predictive values and overall test accuracy for diagnostic prostate and breast biopsies.
