Active clinical trials for "Adenocarcinoma"

Gold markers implanted in the prostate are used frequently for position verification of the prostate during external-beam radiotherapy. By using the markers as a surrogate for the prostate itself, not only set-up errors, but also the internal motion of the prostate relative to the bony anatomy can be identified. It is thus believed that escalated dose marker guided radiotherapy should result in better biochemical control compared to conventional external beam radiotherapy, with a similar or lower incidence of toxicity. However, clinical data to support this is still limited. The purpose of this study is to directly compare late toxicity as well as biochemical control between patients treated with dose escalated marker guided radiotherapy versus conventional dose non-marker guided radiotherapy who has otherwise been treated with similar radiotherapy planning techniques and equipment. Prostate magnetic resonance imaging has undergone several technical improvements and shows promises for prostate tumor detection and localization. In addition to morphological information, magnetic resonance imaging allows an estimation of physiological properties of tissues. Diffusion-weighted magnetic resonance imaging is sensitive to restriction of diffusion of water molecules, and dynamic contrast enhanced magnetic resonance imaging can analyze tissue micro vascular properties. Multi para metric magnetic resonance imaging combining Diffusion-weighted and Dynamic contrast enhanced has demonstrated its value in distinguishing malignant from benign prostate tissue. Higher radiation dose levels were consistently associated with improved biochemical control outcomes and reduction in distant metastases. Radiation dose was one of the important predictors of long-term biochemical tumor control. Dose levels < 70.2 Grey and 70.2-79.2 Grey were associated with 2.3 and 1.3-fold increased risks of pro static specific antigen relapse compared with higher doses. However, further dose escalation to the whole gland is limited due to an unacceptable high risk of acute and late toxicity. Moreover, local recurrences often originate at the location of the macroscopic tumor, so boosting the radiation dose at the macroscopic tumor within the prostate might increase local control. A reduction of distant metastases and improved survival can be expected by reducing local failure. Treating the dominant focus or boosting the dose to this area while reducing the dose to as much healthy tissue as possible has significant potential for improving treatment.

The purpose of this study is to evaluate the efficacy of oral solution Oncoxin-Viusid in the reduction of acute toxicity of Radiotherapy (RTP) and Chemotherapy (QTP) in patients with histological diagnosis of cervical cancer and endometrial adenocarcinoma. This is a phase II, prospective, randomized and double blind clinical trial, which will include 66 patients assigned to 2 treatment arms: 33 patients will receive conventional treatment, plus a placebo of the nutritional supplement and another 33 patients will receive along with the conventional treatment the Oncoxin-Viusid nutritional supplement produced by the Catalysis Laboratories of Spain. Patients will receive oral treatment throughout the onco-specific treatment and up to 3 weeks after completion.

A prospective, open, multicenter, randomized III trial with two arms: Arm A: Primary tumor resection , followed by chemotherapy Arm B: Chemotherapy alone. Compare overall 2-year survival rates in patients treated for resectable rectal adenocarcinoma with unresectable metastasis, treated either with the primary tumor resection with chemotherapy +/- target therapy, or with chemotherapy (+/- target therapy) alone.

To evaluate tolerance to and efficacy of bevacizumab in the treatment of MCRC in elderly patients, we propose a phase II randomised study comparing a chemotherapy + bevacizumab arm with a chemotherapy alone arm in the first-line treatment of MCRC in patients aged 75 years and older. This study is destined to continue as a phase III trial if both arms meet the selection criteria to show or not the benefits of treatment with bevacizumab combined with chemotherapy.

They include patients who are candidates to complete concurrent treatment with endocavitary brachytherapy External radiation therapy + more QT based weekly cisplatin.

This trial tests new methods and materials for the real-time chemotherapy-associated side effects monitoring support system (RT-CAMSS) in patients with gastrointestinal cancers undergoing chemotherapy. RT-CAMSS is a monitoring support system that provides patients with evidence-based information and side-effect management and coping skills, emotional support and validation, and proactive care via text messages and questionnaires as they undergo chemotherapy.

This study will add an immunotherapy component to chemotherapy and radiation treatment in patients who have pancreatic cancer. The objective of this study is to see if the combined treatment is safe and feasible, and if a larger study is warranted.

This is a pharmacogenic, prospective, and multicenter study in patients with advanced lung adenocarcinoma.

This randomized phase III trial studies two different schedules of zoledronic acid to compare how well they work in reducing bone-related complications in patients with breast cancer, prostate cancer, or multiple myeloma that has spread to other places in the body and have bone involvement. Bone-related complications are a major cause of morbidity in patients with metastatic prostate cancer, breast cancer, and multiple myeloma. Zoledronic acid may stop the growth of cancer cells in the bone and may help relieve some of the symptoms caused by bone metastases. It is not yet known whether giving zoledronic acid more or less frequently is more effective in treating patients with metastatic cancer that has spread to the bone.

This will be a phase I study. This phase I study is not a standard drug dose escalation study, but rather a Clinical System Performance Evaluation Trial of a therapeutic device. However for purposes of this protocol we will refer to this portion of the trial as a phase I study. The purpose of this study is to demonstrate the feasibility and clinical practicability of the registered ultrasound and fluoroscopy (RUF) in combination with CMS Interplant system® in an initial cohort of 6 patients. This will involve demonstrating the feasibility of using the system in an actual operating room environment as well as obtaining a preliminary assessment of the accuracy and performance of the source location algorithm by comparing with postoperative CT dosimetry. The Primary endpoint of this study will be evaluation of the feasibility of using the RUF system and of performing real-time optimization in the operating room environment. The Secondary endpoints of this study will be: Acute and late toxicity as assessed by IPSS, SHIM, and EPIC questionnaires at multiple follow-up intervals. PSA-free survival. Study Population: The target population will be patients with a diagnosis of adenocarcinoma of the prostate who are seen in consultation at the Johns Hopkins Hospital. Approximately 360 patients per year with the diagnosis of prostate cancer are seen in the Department of Radiation Oncology at Johns Hopkins Hospital. Of these patients, approximately 45% have low-risk (T1a-T2a, Gleason 6 or less, PSA 10 ng/ml or less) or intermediate-risk disease and are suitable for brachytherapy based on disease risk. Within this group of patients, approximately 70% are eligible for brachytherapy based on gland size and no prior transurethral resection of prostate (TURP). Approximately 80% of patients offered brachytherapy at consultation decide to receive their treatment at Johns Hopkins. Overall, we currently perform 2 brachytherapy procedures per week on average, for a yearly total of approximately 90 cases. For purposes of homogeneity of treatment and patient population, this protocol will only enroll patients currently treated at this institution with brachytherapy alone, and will not enroll patients (intermediate or high risk disease) who will require external beam radiation in addition to brachytherapy.
