Filter by:By obtaining clinical specimens from participants with triple negative breast cancer (TNBC), colorectal cancer (CRC), high grade serous ovarian cancer (HGSOC), and other select tumor types to establish and profile as freshly implanted tumors in mice, the aim of this study is to identify agents with predicted activity in the host patient while also potentially providing them with personalized cancer treatment options
Outcome measurement for patients with gastric, ovarian, colorectal, or pleural cancer/mesothelioma with peritoneal/pleural carcinomatosis undergoing pressurized intraperitoneal/intrathoracal aerosol chemotherapy (PIPAC/PITAC) with cisplatin and doxorubicin or oxaliplatin. Record of (partial/total) tumor response rate via survival rate, time until tumor progression (according to RECIST-criteria), peritoneal carcinomatosis index (PCI) before and after therapy, histological tumor progression/regression, ascites/pleural affusion volume, degree of tumor cell apoptosis.
Randomized trials have already demonstrated that geriatric intervention was able to improve survival in the general elderly population but only a few have been performed in cancer patients. At the end, these data are not sufficient to consider geriatric intervention as validated in this setting. Case Management, coordinated by a geriatrician and a trained nurse, could improve prognosis of elderly patients with cancer. This approach, can be integrated in daily oncology practice. This strategy will be compared to usual oncological management in a randomized phase III trial.
Colorectal cancer is an aggressive malignancy with a poor overall outcome. The purpose of this study is to evaluate the feasibility, safety and efficacy of neoadjuvant oxaliplatin, irinotecan combined with 5-fluorouraci/leucovorin or S-1 or capecitabine in patients with resectable colorectal cancer.
The aim of the project is to study the role of minimally invasive imaging methods, such as magnification endoscopy with narrow-band imaging (M-NBI) combined with confocal laser endomicroscopy (CLE), in correlation with immunohistochemical analysis, for assessing the angiogenesis status of patients with gastrointestinal tumors, in particular with colorectal and gastric cancer. Angiogenesis, i.e. the process of forming new blood vessels, represents an essential event for tumor growth and metastasis and the importance of its understanding stems from potential applications for diagnosis, prognosis stratification and mainly from the possibility of developing and improving targeted therapies. While current methods for evaluating tumor vascularity are based on immunohistochemistry techniques with microvascular density (MVD) calculations, these imply repeated tissue sampling and are not feasible in the context of clinical practice. Imaging techniques might overcome limitations associated with MDV measuring, obtaining both functional and morphological information and enabling repeated evaluations that are necessary for the assessment of a dynamic process as angiogenesis during follow-up of targeted therapies. NBI is a digitally enhanced endoscopic imaging technique that uses optical filters to illuminate tissue with light at blue and green wavelengths. These are selectively absorbed by hemoglobin and, as a result superficial vascular networks are highlighted and morphological changes in capillary patterns can be described for different lesions. CLE represents a revolutionary technology that enables endoscopists to collect real-time in vivo histological images or "virtual biopsies" of the gastrointestinal mucosa during endoscopy, and has raised significant interest for the potential clinical applications and numerous research possibilities. After intravenous administration of fluorescein as a contrast agent, CLE enables real-time visualization of the tumor vasculature, which is structurally and functionally altered compared to the normal vascular networks. Therefore M-NBI will be used for enhanced visualization of morphological changes of the superficial capillaries, while CLE will be directed towards vascular regions of interest for characterization of these changes at the microscopic level. Furthermore, imaging studies will be backed by MVD calculation using immunohistochemical methods, based on tissue samples harvested during endoscopic procedures.
observational prospective study, designed for patients with colorectal cancer receiving for the first time 5-FU or capecitabine, with or without other chemotherapy combinations.
Acute colorectal obstruction has been reported to occur in 7 - 29% of all colorectal malignancies, but emergent surgical decompression is associated with high morbidity and mortality rates. Recently, self-expandable metal stents(SEMS) have been suggested as an alternative to surgery and effectively decompress the colonic obstruction and allow for bowel preparation and elective surgery. Theoretically, SEMSs are classified into uncovered stents and covered stents. Covered stents have the advantage of less frequent stent occlusion by tumor in-growth and the disadvantage of a high risk of stent migration, whereas uncovered stents are associated with less stent migration, although they appear to be more prone to tumor ingrowth. To overcome the drawbacks of conventional stents, a double-layered combination covered stent was developed. In the present study, the investigators evaluated the efficacy and safety of the newly designed covered stent by comparing it with the uncovered stent in patients with malignant colorectal obstruction.
The purpose of this study is to compare the safety and efficacy of laparoscopic resection with natural orifice specimen extraction versus conventional laparoscopic surgery for sigmoid colon or rectal cancer.
This study evaluates the safety and effectiveness of pre-operative artesunate given orally once a day for 14 days prior to surgery in patients with Stage II/III colorectal cancer. Artesunate is an established antimalarial drug with an excellent safety profile, is well tolerated and affordable. A number of laboratory studies and one small pilot clinical study in patients with colorectal cancer have shown that artesunate can reduce the proliferation and growth of cancer cells. Two hundred patients diagnosed with Stage II/III operable colorectal cancer will be randomly allocated to receive oral artesunate 200mg daily or a matching placebo for 14 days prior to surgery. Patients will be followed up closely for 5 years to see if giving artesunate preoperatively reduces the risk of cancer recurring after surgery.
The main purpose of this 3-part study is to evaluate the safety and efficacy of the study drug known as LY2880070 in participants with advanced or metastatic solid tumors.
