Filter by:The main purpose of this study is to determine the effects (good and bad) Iressa plus anastrozole has on patients with relapsed ovarian cancer.
Phase I will determine the MTD and evaluated the safety profile of oral lenalidomide on days 1-21 when given with liposomal doxorubicin on day 1 of every 28 day cycle Phase II will commence once the MTD is established, additional subjects will be enrolled and receive oral lenalidomide on days 1-21 with liposomal doxorubicinon day 1 in 28 day cycles until disease progression is documented.
Phase I will determine the MTD and evaluated the safety profile of oral lenalidomide on days 1-14 when given with topotecan on days 1-5 of every 21 day cycle Phase II will commence once the MTD is established, additional subjects will be enrolled and receive oral lenalidomide on days 1-14 with topotecan on days 1-5 in 21 day cycles until disease progression is documented.
We have identified insulin-like growth factor binding protein (IGFBP)-3 as an invasion suppressor gene in ovarian endometrioid carcinoma, and showed association with lower cancer migration, invasion and metastasis. Recently, a novel model of ovarian EC formation from endometriosis was reported, and PTEN was found to be a major protein involved. Inactivation of PTEN has been reported in some ovarian EC tumors and methylation was suggested as one of the major epigenetic changes. This tumorigenesis model has lots of similarity to our established invasion model. Therefore, we plan to study the important of PTEN expression in ovarian EC and if inactivation of PTEN and IFGBP-3 is through methylation. Furthermore, by studying the signal transduction pathways using PTEN and IGFBP-3 transfection, we plan to study the mutual interaction between PTEN and IGFBP-3 on the suppression of tumor invasion in ovarian EC.
Ovarian cancer is the first in mortality rate of the gynecologic malignancies and the overall 5-year survival rate of ovarian cancer is only 20–30%. Besides, the incidence of ovarian cancer increased in recent years in Taiwan. Ovarian cancer is indeed a disease that should be respected, however, there has only been a little research done focusing on it in Taiwan. Patients with ovarian cancer who have stage I disease (localized to ovaries) after optimal surgical staging do not need any adjuvant therapy. In contrast, patients with disease spreading beyond the ovaries have median survival rates that decrease to < 10% for patients with bulky residual disease after surgery and treated with platinum-based combination chemotherapy. In developing effective therapy for ovarian cancer, there should be a distinction between preventative and therapeutic approaches. Immunoprevention will be developed for women who are at an increased risk for the development of ovarian cancer. In contrast, immunotherapy would be used as an adjuvant to surgery or in combination with chemotherapy or other biologics as chemoimmunotherapy or biochemoimmunotherapy. Mesothelin is expressed in some normal epithelial cells and is elevated in certain carcinomas. Mesothelin has been reported to be selectively overexpressed in most of the non-mucinous ovarian carcinomas. In addition, the specific epitopes of mesothelin in the HLA-A2 and A24 haplotype have been identified. It seems that mesothelin has the potential to be a target antigen for the immunotherapy of ovarian cancer. So the investigators would like to provide this proposal to address the development of mesothelin -specific immunologic assays. There are two aims in this project: 1. to develop and utilize assays to measure cytotoxic T lymphocytes (CTLs) to mesothelin, and 2. to evaluate the mesothelin-specific immunologic responses between normal control and ovarian cancer patients.
Comparison of the patient compliance treosulfan oral vs. intravenous (defined as end of therapy for the patient)
Comparison of topotecan weekly vs. topotecan day 1-5. The compatibility and activity are to be examined.
The combination of paclitaxel and carboplatin in a three weeks schedule has emerged as the current standard approach for the adjuvant treatment of ovarian cancer. Based on a phase I study now a multi-center phase II-trial was conducted.
Compatibility of the topotecan therapy in combination with carboplatin.
Pegylated liposomal doxorubicin (PLD) formulation has been approved for the treatment of recurrent ovarian cancer (ROC). Toxic skin reactions were reported as being the dose-limiting toxicity and have an impact on patients' quality of life (QoL). The primary aim of this study was to optimise the toxicity profile by choosing a biweekly schedule of PLD Furthermore, QoL was investigated. Secondary objective of this study was to evaluate the response rates of this new regimen.
