The synchronous and consecutive (metachronous) development of two or more primary adenocarcinomas accounts for 3 to 5% of cases of colorectal cancer. Aim of this study is to review our experience in the management of patients with synchronous and metachronous lesions, and reach conclusions regarding their optimal diagnosis, treatment and follow-up. ⋯ Patients with colorectal cancer must be followed up regularly after surgery. Follow up aims at early diagnosis and treatment of metachronous lesions that can appear many years after diagnosis of the primary lesion. Preoperative colonoscopy is an invaluable diagnostic (biopsy) and staging (exclusion of synchronous lesions, localization of the primary) modality, dictating the surgical approach. Additionally, it contributes to cancer prevention allowing the discovery and removal of small polyps before their transformation.

Hemodialysis (HD) patients are exposed to persistent inflammatory state. Erythropoietin resistance is known to be strongly associated with chronic inflammation. Aim of the study was to analyze the effect of elevated inflammatory markers on hemoglobin levels and rhEPO requirements in stable patients of our hemodialysis center. ⋯ A better management of anemia might improve inflammatory state and survival in this population.
