Filter by: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.
Patients face multiple stresses and challenges in the aftermath of cancer diagnosis. Despite needs perceived by elderly patients might differ from those of younger patients, there is a paucity of published data assessing the specific evolution and relevant determinants of health-related quality of life (HRQoL) in older patients with cancer. Such determinants may include cancer type/location/stage, treatment type/intensity, comorbidities, nutritional status or socioeconomic features, but also practical organization of care -frequency, geographical distance, supporting measures -, or psychosocial and material support - social network, housing conditions and contextual neighborhood features. Comparatively to dementia or cancer in younger patients, little is known in the oncogeriatric field of the impact on caregivers' perceived burden and HRQol of the support they provide to patients. Further, the potential interactions between patients' and caregivers' HRQoL remain largely unknown, while caregivers are often themselves old with chronic diseases and/or daily living activities' limitations. The DEQOLAGE study is a prospective observational cohort study that aims to describe the HRQoL of patients aged over 70 years with a colorectal or prostatic cancer during the first year following the diagnosis of the disease as well as the HRQoL and burden in their main caregivers. This study will allow a comprehensive assessment of multiple determinants of HRQoL operating at different levels, including individual (cancer type/location/stage, treatment type/intensity, comorbidities, nutritional status or socioeconomic features), contextual (social network, housing conditions and contextual neighborhood features) and organizational factors (frequency, geographical distance, supporting measures). We also hypothesize that complex interactions may operate between patient's and caregiver's HRQoL and perceived burden. Quality of life measurement will be based on two recent scales specifically designed for the elderly to confirm their psychometric properties and in-field feasibility.
observational prospective study, designed for patients with colorectal cancer receiving for the first time 5-FU or capecitabine, with or without other chemotherapy combinations.
Endoscopic resection of adenomas in the colon is the cornerstone of effective colorectal cancer prevention. Endoscopic mucosal resection (EMR) is currently the most used technique for resection of large distal colorectal adenomas, however, maintains some important limitations. In large lesions, EMR can often only be performed in a piecemeal fashion resulting in relatively low R0-resection rates and high recurrence rates. Endoscopic submucosal dissection (ESD) is a newer procedure that is more difficult resulting in a longer procedural time, but is promising due to the high en-bloc resection rates and the very low recurrence rates. The aim of this multicenter randomized study is to compare EMR and ESD with regard to recurrence rates and radical (R0) resection rates, and to put this into perspective against the costs and complication rates of both strategies and the burden perceived by patients on the long term-term.
The purpose of this study is to evaluate the safety and effectiveness of robot-assisted simultaneous resection in selected patients with sigmoid colon cancer or rectal cancer liver metastases, and compared with the traditional open procedure.
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 purpose of this study is to observe whether hepatic infusion by oxaliplatin, irinotecan and raltitrexed with or without embolization by lipiodol or microspheres are effective in the treatment of refratory liver metastasis from colorectal cancer.
