Filter by:Protein arginine methylation is an important process, which regulates diverse cellular functions including cell proliferation, RNA stability, DNA repair and gene transcription. Based on literature search, protein arginine methyltransferase (PRMT) indeed plays important roles in colon cancer pathophysiology. The PRMT expression level is involved in colon cancer patient's survival and has been suggested to be a prognostic marker in colon cancer patients. Recently, our group found a novel methylation on epidermal growth factor receptor (EGFR), which affected EGFR downstream signaling. investigators further observed the methylation event on EGFR not only regulated tumor growth in mouse xenograft model but also influenced cetuximab response in colon cancer cell lines. To further study the clinical correlation between EGFR methylation and cetuximab response, we propose to detect EGFR methylation level in paraffin embedded tissue samples from colorectal cancer patients with or without cetuximab treatment by IHC staining and analyze its correlation with cetuximab response. This study will provide an insight to the strategy of colorectal cancer therapy.
Main outcome: Assess the impact of cancer-related survival at 2 years in patients with unresectable metastatic colorectal cancer treated with chemotherapy alone versus surgery followed by chemotherapy. To assess overall survival. To evaluate postoperative morbidity and mortality in patients treated with resection of the primary tumor. Assess complications and meed for surgery in patients treated with systemic chemotherapy only during the course of the disease. Identify and describe the complications related to chemotherapy and toxicity in the short and medium term systemic treatment. Assessing the quality of life questionnaire QLQ-C30 and QLQ-CR29. To study prognostic survival factors. Method: multicenter randomized clinical trail (22 hospitals). Two parallel group in which to evaluate two therapeutic strategies for colorectal cancer metastasis unresectable stage IV: chemotherapy alone versus primary tumor resection plus chemotherapy. Subjects: patients with unresectable nonmetastatic colorectal cancer. Hypothesis:Surgical resection of the primary tumor in stage IV colorectal patients with unresectable synchronous metastases increases by 14% overall survival compared to patients receiving systemic treatment with chemotherapy without resection of the primary tumor (survival of 34% vs 20%).
This is a randomized Phase 1 study to evaluate the effects of Veliparib on cardiac repolarization in patients with solid tumors who's cancer has recurred or is no longer responding to current treatment.
This pilot clinical trial studies comprehensive gene sequencing in guiding treatment recommendations in patients with metastatic or recurrent solid tumors. Studying samples of blood and tissue from patients with cancer in the laboratory may improve the ability to plan treatment.
Colorectal neoplasms are the third most common malignancies in the United States. Patients with metastatic (stage IV) colorectal cancer have a median life expectancy of 2 years. The response rates to chemotherapy range from 35-40%. Epidemiologic evidence suggests that soy compounds may reduce the incidence of colorectal cancers. Laboratory analyses demonstrate that genistein, a soy-derived compound, may inhibit Wnt signaling, a pathway activated in majority of colorectal cancers. Laboratory observations also demonstrate that genistein may augment growth inhibition when combined with chemotherapeutic agents of 5-Fluorouracil and platinum compounds. Based on pre-clinical data the investigators hypothesize that combining genistein with the standard of care chemotherapeutic regimens will reduce chemotherapy resistance and improve response rates in patients. The aim of the study is to add genistein to the regimens of FOLFOX or FOLFOX-Avastin in patients with newly diagnosed stage IV colon or rectal neoplasms.
In health care, the phone has emerged as a clinical tool in its own right, especially for the development of psychological support to patients and that, in many pathologies. Its potential in the development of psycho-social support was quickly identified. However, to our knowledge, no prospective, randomized studies have evaluated the impact of a telephone call to both the anxiety and the management of side effects of neoadjuvant or adjuvant chemotherapy. The patient incomplete care by the hospital system and the general practitioner during chemotherapy, as well as the lack of information and poor preparation and / or management of side effects, are a source of distress and lead to a decrease quality of life for the patient and his family. We propose to determine on a population of 280 patients, the impact of two phone calls during 3 first inter-treatment intervals on the overall measure of mood states of the patient and his principal caregiver (anxiety, depression, confusion, angry, fatigue, force and interpersonal relation). We will also study the gain in quality of life, on anxiety level, frequency and severity of toxicities, as well as emotional comfort of the procedure.
The purpose of this study is to determine whether anesthesia maintained with propofol results in better one- and five-year-survival than anesthesia maintained with sevoflurane.
The purpose of this study is to determine the safety, tolerability and ability to stimulate hGCC-specific antibody and killer T cell immune responses of an Ad5-hGCC-PADRE vaccine in stage I and stage II Caucasian and African American colon cancer patients.
This study aims to compare the results of colonic surgery performed by single and multiport laparoscopy.
There is now overwhelming evidence documenting the efficacy of psychotherapy in the treatment of depression in the general population. Surprisingly, however, given the high prevalence of depression in cancer patients, there are very few studies on the efficacy of psychotherapy in this population. Published studies of psychotherapy in cancer patients generally include patients with high heterogeneity of psychiatric diagnosis and frequently include patients without a psychiatric diagnosis, with the aim of preventing the appearance of a psychiatric disorder. This heterogeneity complicates the interpretation of the efficacy and specificity of these interventions. Specifically, the efficacy of psychotherapy for major depression in patients with cancer is unknown.
