Filter by:Cancer is the leading cause of mortality in the investigators country. According to the statistics of the Department of Health, the incidence of ovarian cancer increased in recent years and the mortality rate is highest in all gynecologic malignancies in Taiwan. Ovarian cancer becomes a more and more important disease gradually in the field of gynecologic malignancies. The classification of histology in ovarian cancer included epithelial ovarian cancer、germ cell tumors、sex-cord cell tumors…etc. Epithelial ovarian carcinoma is the most common ovarian cancer clinically. Early diagnosis is difficult due to the lack of obvious initial symptoms, so ovarian cancer patients are usually at advanced stage when the diagnosis is confirmed. The prognostic parameters for ovarian carcinomas include tumor stage, histological subtype, degree of malignancy, residual tumor after surgical intervention and the response to chemotherapy. However, the possible etiology and mechanism of ovarian cancer is still unclear. However, there is no epidemiologic data of ovarian cancer in Taiwan. Therefore the investigators propose this study to use Taiwan registry database provided by Department of Health to analyze the epidemiology and prognosis of ovarian cancer patients in Taiwan.
The purpose of this trial is to estimate the therapeutic efficacy of the experimental targeted regimen including the EGFR antibody panitumumab (in combination with carboplatin and either pegylated liposomal doxorubicin or gemcitabine) in relation to the respective standard combination in patients with a KRAS wildtype with platinum-sensitive recurrent ovarian cancer. It is expected that the progression free survival rate at 12 months is improved by the targeted regimen.
Specific aims: Identification and characterization of cancer stem cell-like population (cancer stem cells or cancer initiating cells) from primary tumor tissue, primary ascites and peripheral blood of ovarian cancer patients and genetically engineered mouse ovarian cancer cell lines. Objectives: In the future, individualized therapy must incorporate analysis of the cancer stem cells or cancer initiating cells of ovarian cancer cells when designing therapeutic strategies for ovarian cancer patients. Aims of this project: 1. Isolation and identification of cancer stem cell-like population (cancer stem cells or cancer initiating cells) from primary tumor tissue, primary ascites and peripheral blood of ovarian cancer patients 2. In vivo tumorigenicity assay will be performed to measure tumor formation from these cancer stem cell-like population when equal numbers were injected into the dorsal fat pad of nude mice. 3. To establish a standard protocol of stem cell-like population maintenance 4. Screening of potential specific biomarkers involved in these ovarian cancer stem cell-like population.
Intend of use: A blood test for Cancer Associated Antibodies (CAAA) is an aid in initial diagnosis of ovarian cancer in women with suspected ovarian pathology as detected by primary diagnostic techniques. Test Description: Blood is collected from patients and serum/plasma is tested for the presence of CAAA on experimental test kit. Objectives: To assess the effectiveness of the CAAA test. Target Population: The study population will include women that have been diagnosed with suspected ovarian cancer (OC), verified by pathology/cytology as patients, women with suspected ovarian cancer but verified by pathology/cytology as non-cancers and a control set of blood samples will be collected from age matched women with no history of cancer. Structure: Women that will be enrolled for the study will be checked for the presence of CAAAb, and the results of the CAAAb test will be compared to the pathology submitted by the physicians in the participating centers for the patient population and to the clinical history for the control population. Sample Size: The investigators will collect at least 50 patients verified by pathology/cytology and for each patient at least two aged matched healthy controls and two aged matched suspected but verified as non-cancers. Total amount at least 250 samples. (Multi center study, statistical rationale provided below). Primary Effectiveness Variables: The effectiveness of the test will be defined by the specificity of the test conditionally that the sensitivity is not lower than a pre-defined level of 95%. Endpoint: The endpoint of this study is to show that the effectiveness is higher than 50%. Clinical Monitor: For each site a dedicated CRO will be appointed to monitor the clinical trials. All data will be stored in a protected internet-based database, and any changes of the data will be traced and recorded.
Ovarian cancer, especially epithelial ovarian carcinoma, has the highest mortality rate among the gynecologic malignancies. The majority of patients with epithelial ovarian carcinoma are diagnosed at advanced stage which has the overall survival rates of only 19-30%. As the advance in the managements which prolonged the overall survival, metastatic lesion in rare location such as brain was noted in few patients of ovarian cancer in recent years. In the retrospective study, the investigators will review the medical records of the ovarian cancer patients with brain metastasis in the investigators hospital to investigate the incidence, clinical courses, optimal managements and possible prognostic factors in the rare condition.
The purpose of this study is to create new tests to identify biomarkers for ovarian cancer so that a screening test can be developed. For patients who have a diagnosis of ovarian Cancer, researchers will use blood samples before and after treatment to see if disease status can be determined by measuring the amount of biomarker.
The primary objective of this phase-II study is to assess the toxicity of consolidation intensity-modulated whole-abdominal radiotherapy using tomotherapy in patients with advanced optimally debulked stage International Federation of Gynecology and Obstetrics (FIGO) III ovarian cancer with a complete remission after adjuvant chemotherapy. 36 patients will be treated to a total dose of 30 Gy in 1.5 Gy fractions. The planning target-volume includes the entire peritoneal cavity and the pelvic and para-aortal node regions. Intensity-modulated whole-abdominal radiotherapy allows an effective sparing of liver, kidneys and bone-marrow (vertebral bodies and pelvic bones).
This research study is looking at tumor tissue samples from patients who have undergone surgery for advanced stage III or stage IV ovarian epithelial cancer. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn how tumor infiltrating T cells can predict how patients will respond to treatment.
A study to examine the combination of temsirolimus and Caelyx® (chemotherapeutic) in advanced or recurrent breast, endometrial and ovarian cancer.
RATIONALE: Drugs used in chemotherapy, such as paclitaxel and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. PURPOSE: This phase II trial is studying the side effects of giving paclitaxel together with cisplatin as first-line therapy and to see how well it works in treating patients with stage I, stage II, stage III, or stage IV ovarian epithelial cancer.
