Filter by:Ovarian cancer is the third most common gynecological malignancy worldwide. Because of late, aspecific symptoms, the disease is usually diagnosed at an advanced stage. Most patients experience recurrence and die as a result of the disease within 5 years. Treatment is a combination of surgical debulking and systemic administered chemotherapy. Intra-peritoneal (IP) chemotherapy with is currently considered the most effective treatment. In patients with at least an optimal surgical debulking, this leads to an improvement in life expectancy from 50 to 66 months. IP administration of chemotherapeutic agents is still not common practice. Furthermore recent studies revealed that cancer cells express a variety of tumor antigens, which can be targeted by the immune system. Also ovarian cancer shows evidence of a role for the immune system in clinical outcome. Novel insights into the mechanism of action of chemotherapy indicate that the efficacy of chemotherapeutic interventions are dependent on the modulation of the immune system. The impression exists that since IP chemotherapy is used, relatively more recurrences outside the abdominal cavity are observed. As of yet, no studies have described pharmacokinetics and pharmacodynamics of IP administered cisplatin and paclitaxel in the blood circulation. The investigators propose to study the use of this aspiration fluid from the IP cavity as a biomarker for the efficacy of chemotherapy intervention, monitor the effect of chemotherapy on IP tumor cells in the peritoneal cavity and monitor the effect of chemotherapy on immune cells present in the IP cavity. As well the investigators propose to correlate the presence and amount of tumor cells in peritoneal fluid with the debulking efficacy and CA 125 levels. Secondary to this the investigators intend to determine the pharmacokinetics of cisplatin and paclitaxel when administered in the IP cavity in the central circulation (plasma) as well as in the peritoneal fluid. In this observational explorative study women, aged younger than 70 years, who will receive standard IP chemotherapy for advanced epithelial ovarian cancer, who are in an adequate physical and biochemical state to receive chemotherapy are included. Immunological cell counts, tumor marker, immunological cell pathway activation and plasma concentrations of cisplatinum and paclitaxel in venous blood and in fluid aspirated from the abdominal cavity will be measured.
Probiotics modulate the gut microflora and immune status in lung cancer who need chemotherapy.
Broadly speaking, the goal of this study is to better understand the influence of chemotherapy treatment on the cognitive and neural mechanisms underlying human behavior. Extant literature lacks diversity in studied cancer populations and treatment protocols, and provides limited understanding of the cognitive abilities that are impaired by chemotherapy. To overcome these limitations, this study will employ a sophisticated battery of tests on an understudied cancer population. Eligible participants will either be patients diagnosed with hematological malignancy (HM) or demographically matched healthy control patients. After HM diagnosis and treatment protocols have been established, patients will be inducted into the longitudinal study comprised of three visits: 1) after diagnosis but prior to chemotherapy treatment (baseline), 2) after one treatment cycle (one month post-baseline), and 3) after three treatment cycles (three months post-baseline). Patients will undergo a test battery designed to measure specific behavioral and neural mechanisms of attention; tests will either be computer-based cognitive tasks or simulated driving tests that immerse patients into virtual driving scenarios. During each test, EEG will be concurrently measured through non-invasive scalp electrophysiology recordings; EEG recordings will reveal underlying neural mechanisms affected by chemotherapy. Additionally, neuropsychological tests of vision, attention, and memory will be administered, as well as questionnaires to evaluate health, mobility, and life space. Finally, blood samples will be collected to examine levels of circulating inflammation-specific proteins typically present in cancer patients. This study will allow us to better understand the mechanisms through which chemotherapy influences cognitive performance. Results from this study will influence the administration of chemotherapy treatments so that patients can continue to receive the highest medical care while maintaining optimal cognitive abilities and quality of life.
The investigators discover the investigators' miRNA tool can be a useful tool to predict the patients with stage II colon who can benefit from chemotherapy.Then the investigators plan to make an observation study that may validation this tool.
The purpose of this study is to determine whether a specially-designed music-narratives are effective in reducing side effects of chemotherapy in 7- to 12-year-olds with cancer.
The purpose of this study is to identify the treatment outcomes of surgical resection with sequential adjuvant chemotherapy and radiotherapy in patients with stage IIIA non-small cell lung cancer and N2 disease at only the sub- or para-aortic level.
Women of reproductive age who will receive treatment for cancer that includes chemotherapy may participate in a study measuring ovarian function over time. Eligible women are asked to complete a questionnaire, a menstrual diary, a brief physical examination, an ultrasound, and a blood test before, during and after cancer treatment.
Whether patients with stage II colon cancer should receive adjuvant chemotherapy or not is still on debate.MicroRNA(miRNA) is a promising tool. Investigators invented a tool consisting of 6 miRNA(miR-21、miR-20a-5p、miR-103a-3p、miR-106b-5p、miR-143-5p and miR-215) that was effective to identify one should accept adjuvant chemotherapy or not. Here investigators randomly assign patients to be assessed by classical pathological features or the miRNA tool of determining who should accept chemotherapy. Disease free survival and overall survival are the end points of observation.
The purpose of this study is to evaluate whether the R0 rate, pathological response degree, patterns of recurrence and long-term outcomes may be initially predicted in patients with locally advanced gastroesophageal junction and gastric cancer treated with a neoadjuvant approach and salvage surgery.
The aim of this study is to evaluate the efficacy of a neoadjuvant approach in patients with locally advanced gastric cancer and the identification of prognostic factors.
