Filter by:In North America, around a quarter a million men are diagnosed with prostate cancer every year, and about 31,000 patients will die of their disease each year. Like other western countries, the incidence in Canada has increased due to an aging population and prostate specific antigen (PSA) screening. This has led to a significant demand on cancer care services for these patients. Prostate cancer patient with high risk features are more often treated with external beam radiation therapy (EBRT) plus two to three years of hormonal manipulation (luteinizing hormone-releasing hormone [LHRH] agonist). The most common radiation dose treatment for these patients is 74-78 Gy in 37-39 daily fractions of 180-200 cGy for a treatment length of 7.5 weeks. This fraction size is believed to offer the best balance between desired tumour kill and unwanted normal tissue injury. Larger fraction sizes of more than 250 cGy (hypofractionation) are usually avoided for curative therapy because late reacting normal tissues. However prostate cancer cells have a unique radiobiology characteristic that suggests that hypofractionated radiotherapy is more efficient at prostate tumour killing than standard fractionation is, and will produce equivalent tumour control with a lower total dose and a shorter overall treatment time. Improved target localization techniques and conformal radiation therapy technology have allowed for dose escalation and hypofractionated radiation delivery in these circumstances with minimal or no increased toxicities. This trial is designed to determine whether high risk prostate cancer patients can be safely treated with a dose escalation hypofractionated radiation therapy in 5 weeks as opposed to the usual 7-8 weeks. These patients will be randomized to either the usual 76 Gy in 38 fractions or 68 Gy in 25 fractions. 3D-Conformal Radiotherapy (3D-CRT) or Intensity Modulated Radiotherapy (IMRT) will be used to deliver the required radiation dose. Patients will also receive 28 months of androgen deprivation therapy (LHRH agonist). The primary outcome of the study is the acute and delayed toxicity and the secondary outcomes include biochemical failure, prostate specific mortality rate, bone metastases free survival, the prognostic and predictive value of several biological variables: presence of the PTEN deletion; expression of FoxP3 gene variants, topoisomerase 2α and cancer testis antigens; expression of X chromosome-linked micro-RNAs; presence of TMRSS2-ERG gene fusion and quality of life. It is planned to recruit 250 patients to this study.
1. The investigators hypothesize that increasing radiation dose to the functional MRI-defined lesion in the prostate bed will result in an improved initial complete response (reduction in prostate-specific antigen (PSA) to < 0.1 ng/mL), which is related to long-term outcome biochemically. 2. Biomarker expression levels differ in the DCE-MRI enhancing and non-enhancing tumor regions (when applicable). 3. 10-15% of men undergoing RT have free circulating DNA (fcDNA) or tumor cells (CTC) that are related to an adverse treatment outcome. 4. Prostate cancer-related anxiety will be reduced in the MRI targeted SRT arm, because the patients will be aware that the dominant tumor will be targeted with higher radiation dose (compared to those pts who were treated on standard arm prior to its closure).
This randomized phase IIA trial studies how well antiandrogen therapy works with or without axitinib before surgery in treating patients with previously untreated prostate cancer that is known or suspected to have spread to lymph nodes. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as antiandrogen therapy may lessen the amount of androgen made by the body. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known if antiandrogen therapy is more effective with or without axitinib before surgery in treating patients with prostate cancer.
The primary objective of this study is to evaluate the predictive value (in terms of remission) of a new technique for detecting circulating, functional, prostate cells among patients with localized adenocarcinoma of the prostate, and prior to any treatment.
The purpose of this study is to find out whether a protein, called mesothelin, found in the blood and tissue can be used as "marker" for esophageal cancer. Doctors at Memorial Sloan-Kettering Cancer Center would like to compare levels of this protein in patients with abnormal cells or tissue of the esophageal to the levels of this protein in patients being treated for cancer for the esophagus.
This phase I/II partially randomized trial studies the side effects and best dose of veliparib when given together with radiation therapy, carboplatin, and paclitaxel and to see how well it works in treating patients with stage III non-small cell lung cancer that cannot be removed by surgery. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether radiation therapy, carboplatin, and paclitaxel are more effective with or without veliparib in treating non-small cell lung cancer.
The clinical hypothesis of this study is that the addition of Panitumumab to the first line treatment combination of docetaxel plus cisplatin will provide benefit to patients with advanced gastric or gastroesophageal junction adenocarcinoma.
Background: It is estimated that in the Netherlands each year approximately 900 patients with gastric cancer or adenocarcinoma of the gastro-oesophageal junction are candidates for chemotherapy. Randomized studies comparing chemotherapy versus best supportive care have shown that survival and quality of life are prolonged with chemotherapy. However, no chemotherapy regimen is clearly superior with regard to prolongation of survival. Therefore, tolerability of treatment and ease of administration (outpatient compared to inpatient) are important considerations for the development of novel treatment schedules. Study design: This is an open-label, multicentre, phase II trial designed to evaluate the efficacy and safety of bevacizumab in combination with docetaxel, oxaliplatin and capecitabine chemotherapy (B-DOC) as first-line therapy in patients with inoperable locally advanced or recurrent and/or metastatic adenocarcinoma of the stomach or gastro-oesophageal junction. In case of HER2 positive inoperable locally advanced or recurrent and/or metastatic adenocarcinoma of the stomach or gastro-oesophageal junction trastuzumab is added to this regimen (B-DOCT). Study Endpoints: Primary endpoint Progression free survival defined as the time measured from B-DOCT study, Protocol version 3.0 dated January 18, 2011 Page 5 / 60 the day of registration to first progression or death. Secondary endpoints Toxicity Overall survival, defined as the time from registration to death Response rate defined as the percentage of partial and complete responses Duration of response defined as time from response to first progression Translational research on pharmacogenomic and biological factors that may predict treatment response.
This is a study to first establish feasibility of the study and then to register the treatment data of adult patients with a diagnosis of intermediate risk of prostate cancer presenting for definitive radiation treatment with either proton radiotherapy or Intensity Modulated Radiation Therapy (IMRT). The investigators propose to employ a hypofractionated strategy with our image guided treatment to further improve cancer control and decrease toxicity.
This phase I trial studies the side effects and the best dose of paclitaxel and carboplatin after cisplatin and radiation therapy in treating patients with stage IB-IVA cervical cancer. Drugs used in chemotherapy, such as cisplatin, paclitaxel, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving paclitaxel and carboplatin after cisplatin and radiation therapy may kill more tumor cells.
