Filter by:The primary objectives of this study are to evaluate the safety and best dose of a regimen including bevacizumab and erlotinib in combination with docetaxel and prednisone. In addition, the investigators wish to evaluate how well these drugs might work against this disease. Bevacizumab and erlotinib are novel drugs that attack the blood vessels supplying the tumor cells and attack a receptor on the tumor cells, respectively. This study has two parts. In the first part of the study, eighteen patients will be enrolled. Patients will receive escalating doses of docetaxel in combination with standard doses of bevacizumab and erlotinib until the safest dose is determined. An additional 37 patients will enter into the second part of the study and all will receive the safest dose. In this part of the study, the effectiveness of this regimen against hormone refractory prostate cancer (HRPC) will be monitored by evaluating prostate-specific antigen (PSA) and objective response of the tumor.
The primary objective of this study is to collect material for study's to assess mechanisms of tumor progression, mechanisms of resistance, isolation of stem cells and biologic markers in tissue, serum and peripheral blood mononuclear cells.
RATIONALE: Diagnostic procedures, such as technetium Tc 99m demobesin-4 followed by single-photon emission computer tomography, CT scan, and MRI, may help find prostate cancer and learn the extent of disease. PURPOSE: This phase I trial is studying the side effects of technetium Tc 99m demobesin-4 and to see how well it works for imaging procedures in patients with prostate cancer.
This is a study of men who have undergone a standard 10 or more core biopsy for detection of prostate cancer and determined to have prostate cancer Gleason score ≤ 7 (low to moderate risk 2-7). Of these men, one arm of a two arm randomized group will be administered a treatment regime of Dutasteride versus the control group who receive standard of care, prior to mapping biopsy. This proposal aims at studying the apparent effect of the use of Dutasteride (3 months) on initial tumor volume (at diagnosis) in men with low volume cancer before undergoing 3D mapping biopsy.
A new solution for guiding the surgeon in robot-assisted laparoscopic radical prostatectomy (RALP) is image-guided navigation using transrectal ultrasound (TRUS). A TRUS-guided intraoperative navigation system using a robotic ultrasound probe manipulator (TRUS Robot) has been developed. The proposed research is a pilot clinical trial of the TRUS Robot and three-dimensional (3-D) navigation software to test its image-guidance ability of helping the surgeon during RALP. This is a dual robot approach, a Tandem-RALP (T-RALP). The TRUS Robot allows a steady holding as well as remote manipulation of the TRUS probe. In addition, the TRUS Robot can track the accurate position of TRUS probe which allows 3-D reconstruction of the images. While the intraoperative TRUS findings will not be used in surgical decision making in this trial, the use of TRUS imaging during radical prostatectomy can potentially improve the visualization of the NVB and subsequently improve postoperative recovery of potency in men. In addition, the 3-D reconstruction images of the prostate gland can potentially provide clear and accurate guidance of surgical landmarks to the surgeon..
The purpose of this research study is to determine the safety of giving ketoconazole, hydrocortisone and dutasteride (KHAD) with lapatinib. Safety is primarily based on dose limiting toxicity (DLT) evaluation at various dose levels (DL). The investigators believe that there is evidence in castrate resistant prostate cancer (CRPC) that two growth factor receptors (EGFR and Her 2/Neu) are increased in prostate cancer (PCa) cells. Both these receptors are turned off by the drug lapatinib. By adding lapatinib, the investigators hope that signaling from the receptors will be turned off and therefore make the participant's cancer more responsive to KHAD treatment.
Neurovascular bundle (NVB) contains capsular vessels to the prostate and cavernous nerves that provides the macroscopic landmark used during nerve-sparing radical prostatectomy. The preservation of NVB during radical prostatectomy improves postoperative recovery of potency and continence. However, the visualization of the NVB during radical prostatectomy can be challenging. Recently, an attempt has been made to use a transrectal ultrasound (TRUS) imaging to delineate the anatomy of the prostate gland and NVB during laparoscopic radical prostatectomy. However, it is difficult to obtain a steady image of TRUS with an operator. The investigators plan to perform a feasibility study to obtain TRUS imaging of the prostate and NVB during robot-assisted laparoscopic radical prostatectomy (RALRP). The investigators plan to use a robot-assisted TRUS probe holder to gently manipulate the probe to obtain steady TRUS images that may aid in visualization and dissection of the NVB during RALRP.
RATIONALE: Conformal radiation therapy uses a 3-dimensional (3-D) image of the tumor to help focus thin beams of radiation directly on the tumor. Giving conformal external-beam radiation therapy in higher doses over a shorter period of time may kill more tumor cells and have fewer side effects. Androgens can cause the growth of prostate cancer cells. Hormone therapy, such as leuprolide acetate, may lessen the amount of androgens made by the body. It is not yet known whether radiation therapy is more effective when given together with or without hormone therapy in treating patients with prostate cancer who have undergone surgery. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared with radiation therapy given together with hormone therapy in treating patients who have undergone surgery for stage I, stage II, or stage III prostate cancer.
A growing body of literature supports the role of angiogenesis in the development and spread of a variety of human cancers including prostate cancer. - Vascular endothelial growth factor (VEGF) expression is low in normal prostate tissue, but markedly increased in tumor tissues, and has a positive association with tumor stage and grade - Plasma VEGF levels are significantly elevated in patients with hormone refractory prostate cancer (HRPC) compared to those patients with localized disease and have been associated with disease progression in other cancer patient population. - The Cancer and Leukemic Group-B demonstrated that VEGF levels correlate with survival. Pazopanib is a potent multi-target receptor tyrosine kinase inhibitor of vascular endothelial growth factor receptors.
The goal of the Phase I part of this clinical research study is to find the highest tolerable dose of Revlimid® (lenalidomide) that can be given in combination with paclitaxel to patients with prostate cancer who have failed treatment with taxanes. The goal of the Phase II part of this clinical research study is to learn if lenalidomide and paclitaxel can help to control prostate cancer. The safety of this combination treatment will be studied in both phases of the study. UPDATE: Study was terminated early due to slow accrual as a Phase I dose escalation study, without progression to Phase II study portion.
