Sensitivity and specificity of a stool DNA multitarget assay panel for the detection of advanced colorectal neoplasia.
Colorectal cancer is the second-leading cause of cancer death. New noninvasive options for screening capable of diagnosing cancer at an early stage are needed to improve compliance and reduce mortality. This study was designed to provide an estimate of the sensitivity and specificity of a multitarget assay panel (MTAP) of stool DNA changes. ⋯ Sensitivity appeared to be equally high for patients with node-negative and advanced disease, as well as for advanced adenomas. This study contained a disproportionately high number of distal cancers and, as such, may not be representative of results in proximal lesions. Although a prospective study in an average-risk population is needed to validate these findings, MTAP may offer an important noninvasive option for population-based screening.

Clinical TrialIrinotecan, oxaliplatin, and 5-fluorouracil/leucovorin combination chemotherapy in advanced colorectal carcinoma: a phase II study.
The purpose of this study was to evaluate the efficacy and tolerance of a combination of irinotecan, oxaliplatin, and 5-fluorouracil (5-FU)/leucovorin in advanced colorectal cancer (ACC). Twenty-six consecutive patients with ACC and an Eastern Cooperative Oncology Group performance status of 0-2 were treated with a combination of oxaliplatin (120 mg/m2 intravenously [i.v.] for 2 hours) on day 1, irinotecan (250 mg/m2 i.v. for 90 minutes) on day 1, and 5-FU (2600 mg/m2 plus leucovorin 500 mg/m2 i.v. in a 24-hour infusion) on day 1 and 15, every 4 weeks. Five of the patients (19.2%) had shown previous chemoresistance. ⋯ Seventeen patients (65.4%) are still alive, and the median overall survival has not been reached yet. This combination of irinotecan, oxaliplatin, and 5-FU/leucovorin is fairly well tolerated and shows promising activity in ACC. This treatment merits further comparison with other combination regimens.
