Filter by:Prostate cancer is considered the fourth most common malignancy cancer in America. However, in Colombia the incidence is higher, and it is considered the second cause of death among men for malignance diseases. In the framework of clinical localized prostate cancer there is a controversy regarding the best predictors of risk and the best treatment options. The actual literature is discussing the possibility of underestimate the disease and actual tools are not sufficient for proper characterization. Is in this context that extended pelvic lymphadenectomy emerges as a stratification tool in prostate cancer that defines the real commitment of the disease. The investigators need to know the characteristics that the disease has on the investigators community so the investigators can generate appropriate therapeutic approach. Thus, the present prospective observational-descriptive multicenter study, want to determine in three referral centers in Bogotá Colombia , the frequency of pelvic node involvement in patients with localized clinical prostate cancer from the stratification achieved by pelvic lymphadenectomy extended.
The metastatic lesions may be very different from the primary tumor because of intrinsic tumor heterogenity, clonal selection through metastatic process and following previous cytotoxic treatments. Metastatic tumor harboring actionable targets or signaling pathways may respond to inhibitory agents directed against specific aberrations irrespective of tumor origin. In the MetAction study, patients will receive therapy based on molecular aberrations in the metastatic lesions, actionable target identification (ATI), rather than on histological tumor type. The ATI rate in an unselected metastatic patient population is uncertain, and response rates associated with ATI based targeted therapy have hardly been reported. In this perspective, The MetAction study is essentially a feasibility study aiming to tailor metastatic cancer therapy based on genomic profiles.
Ipilimumab adds a clinical benefit to radiation therapy in patients with melanoma metastatic to the brain. Melanoma is the third most common cancer causing brain metastases, after cancers of the lung and breast, which appears to reflect the relative propensity of melanoma to metastasize to the central nervous system (CNS). Brain metastases are responsible for 20 to 54 percent of deaths in patients with melanoma, and among those with documented brain metastases, these lesions contribute to death in up to 95 percent of cases, with an estimated median overall survival ranging between 1.8 and 10.5 months, depending upon other prognostic factors. Ipilimumab is an anti-Cytotoxic T-Lymphocyte Antigen 4 (anti-CTLA4) monoclonal antibody that has demonstrated a clinically relevant and statistically significant improvement in overall survival, either alone (second line) or in combination with dacarbazine (DTIC) in 1st line. Ipilimumab has shown activity against brain metastases. According to the European Medicines Agency (EMA) approved label for Yervoy®, the use of glucocorticoids at baseline (commonly prescribed when brain metastases are diagnosed) should be avoided before the administration of ipilimumab. Data show that the use of even high doses of glucocorticoids for the management of immune-related adverse events do not decrease the efficacy of Yervoy®. There is no documented experience on the efficacy of Yervoy® when given concomitantly with radiation therapy and glucocorticoids. In experimental models, radiation therapy is synergistic to anti-Cytotoxic T-Lymphocyte Antigen 4 (anti-CTLA4) strategies (abscopal effect). There are no published results from clinical trials on the interaction between radiation therapy and ipilimumab.
This study will look at two new technologies being developed for measuring cancer in bones. One of these technologies is a substance called Sodium Fluoride (NaF). Fluoride is a normal body substance. The amount that patients will receive has been shown to be very safe. One study of over 400 patients showed no adverse reactions after receiving the recommended dosage. NaF (known as a radiotracer) is taken up into the bones under a normal process and researchers can measure the amount within patient's bones through an imaging system called a Positron Emission Tomography/Magnetic Resonance Imaging (PET/MRI). This system combines aspects of both a PET study as part of the regular standard of care and an MRI study. The belief is that the combination of these two studies will be better than either study alone.People who have enrolled in this study will receive their clinically requested PET/CT scan as part of their normal diagnostic care and will follow all the said recommendations for this study such as not being pregnant, having fasted overnight, etc. Subjects will return within 7 days for a 10 mCi NaF PET/MRI study. The patients' imaging time will be up to 120 minutes depending on the MRI sequences acquired. Imaging for the PET portion of the study will take approximately 20-30 minutes with the rest of the time devoted to MRI sequences.
Capecitabine, oxaliplatin, irinotecan and bevacizumab as perioperative strategy of borderline and/or high risk resectable colorectal cancer liver metastases
The purpose of this study is to collect and bank samples of blood and tissues (such as brain tissue or lymph nodes), as well as cerebrospinal fluid (CSF), which is the fluid that bathes and cushions the spinal cord. The investigator will analyze DNA biomarkers in the samples. The investigator hopes that by studying the biomarkers, he can develop tests in the future that can detect central nervous system (CNS) metastasis in blood samples before they show up on x-ray and develop medicines that can specifically target CNS metastasis.
This is a Phase 2 study to see if an investigational drug, ANG1005, can shrink tumor cells in breast cancer patients with recurrent brain metastases.
This pilot clinical trial studies fludeoxyglucose F18 (FDG)-positron emission tomography (PET) in imaging patients with prostate cancer treated with ranolazine. Diagnostic procedures, such as FDG-PET, may help find prostate cancer and find out how far the disease has spread. Giving ranolazine may enhance FDG-PET imaging by increasing the amount of glucose available for uptake by the scan.
The incidence of brain metastases (BM) in metastatic breast cancer is increasing, due to the improvement in the control of systemic disease, and due to an improved detection through imagery. The treatment management of single BM remains controversial. Indeed, even though it is widely accepted that local treatment increases the median survival time in patients having a good prognostic status, the adding of "adjuvant" whole-brain radiation therapy (WBRT) is currently subject to controversy, due to its potential toxicity. Yet, two randomized trials have demonstrated a clear increase in intra-cerebral recurrence and in death from neurologic origin in case of absence of "adjuvant" WBRT, without change in overall survival (but overall survival was not a primary endpoint in any of these studies). The data from literature on cognitive toxicity (CT) of WBRT on BM are scarce and sometimes controversial. CT of WBRT affects the subcortical frontal functions. It is postulated that the alteration of hippocampal neurogenesis (mainly due to inflammation process), situated in the subgranular zone of the dentate gyrus, has an essential role in the development of these brain dysfunctions. It has been shown that the incidence of BM in the hippocampal region (hippocampus + 5mm expansion) is low, in the range of 8,6%. New irradiation techniques, in particular intensity-modulated radiotherapy associated with rotational radiotherapy, allow to modulate the dose on an intra-cerebral structure, all the while distributing an adapted dose to the remaining brain. This prospective, randomized study, will compare, through a battery of neuropsychological tests, the cognitive impact of WBRT of 40 Gy in 20 fractions with or without hippocampal avoidance by intensity modulated radiotherapy, in patients presenting with a single operated brain metastasis of breast cancer. If the hippocampal avoidance leads to a significant improvement in cognitive function, this radiotherapy scheme could become the standard postoperative treatment to be proposed to patients presenting the best prognostic factors. This would allow to prevent long-term cognitive deficit, while preserving WBRT benefit on intra-cerebral control. Justification of evaluation criteria : Principal criteria : Evaluation criteria to assess cognitive toxicity have been selected on the basis of the recommendations from C. Meyers and P. Brown, who propose an adapted test battery to evaluate memory, verbal function, visual and motor coordination, and executive function. The selected tests have been validated, also in French. They comprise HVLT-R (Hopkins Verbal Learning Test Revised), COWAT (Controlled Oral Word Association Test), Grooved Pegboard test, TMT A and B (Trailmaking tests A and B), and MMSE. The calculation of patient numbers was based on the HVLT-R test, as memory is thought to be the most frequently affected domain. The tests will be performed before treatment ("baseline" cognitive function), at 4 months and at 12 months. In case of a missing answer to the evaluation tests, the reason(s) for not answering will be noted. Secondary criteria : Quality of life : QLQ-C30, QLQ-BN20, ADL, IADL Intra-cerebral Progression-free survival (PFS) Overall survival.
