Filter by:This phase I dose escalation study will evaluate IGF-Methotrexate conjugate (765IGF-MTX) in patients with advanced, previously treated tumors. 765IGF-MTX is administered as an IV infusion over 1 hour on days 1, 8 and 15 of a 28 day cycle. Treatment continues until disease progression, unacceptable toxicity, or patient refusal. Assessment of response will be confirmed with imaging studies performed at the end of cycle 2 +/- 7 days, and every 2 weeks thereafter.
Malignant ascites represents a severe clinical problem for physicians and patients being confronted with this common symptom of advanced-stage gastrointestinal cancer. Unfortunately, there is no standardized and evidence-based treatment for malignant ascites and therapies which are commonly being used are only temporarily effective. Newer modes of therapy, such as the application of the tri-functional antibody catumaxomab, are associated with significant side effects and are limited to patients in stages of good overall performance. Therefore, there is still an urgent need for more effective, longer-lasting, and less toxic modes of treatment for peritoneal effusions caused by gastrointestinal cancers. Preclinical data strongly suggest that bevacizumab might be a very effective agent for the treatment of malignant ascites, which is in large part caused by the hyperpermeability-promoting factor VEGF. Emerging clinical results from cancer patients with malignant ascites treated with bevacizumab add further support to this idea. Bevacizumab has been tested in a variety of large clinical trials, has a good toxicity profile, and is effective in a number of human cancers underlying malignant ascites. In the present study, Bevacizumab will be administered as an intraperitoneal infusion at an absolute standardized dosage of 400 mg. This dosage was chosen because it is comparable to the approved standard dosage for intravenous administration which was also used in both studies reporting the successful and safe intraperitoneal administration of Bevacizumab to patients with malignant ascites. Finally, a standardized dosage seems more practical in the particular patient population treated in this study.
This study will help us know the effects of Vitamin D pills in Blacks. The results of this study may be the first step in creating ways to prevent the risks of colon and prostate cancer. It will also help us develop ways to reduce colon cancer and prostate cancer among Blacks. This study will find out if Vitamin D pills can increase Vitamin D to healthy levels in our bodies.
Transitoriness can be defined as confrontation with life's finitude. Cancer patients are perceived to experience this confrontation due to their diagnosis. It is perceived to impact cancer patients' ways of coping with the disease situation. In this study, cancer patients' levels of uncertainty, transitoriness and their perceived locus of control are assessed. It is aimed at exploring the association of uncertainty, locus of control, transitoriness and quality of life. If a stronger correlation of one or the other issue with quality of life can be discovered, it will inform the development of an adequate evidence-based nursing intervention to better support patients' coping with the disease.
