Hepatectomy is the main treatment of sizable benign or malignant liver tumors (primary or metastatic). The liver remnant is essential to be adequate in both volume and function in order to avoid severe complications or morbidity of the patient. Therefore the evaluation of the liver function and the future liver volume has become of paramount importance in the preoperative patient assessment. Computed tomography has a significant contribution in the multimodality preoperative imaging of the lesion and the liver infrastructure, as well as of the liver volume. The present article reviews the existing data regarding the impact and efficacy of the patents developed to enhance the capabilities of computed tomography, in terms of evaluating liver volume, function and surgical anatomy. © 2013 Bentham Science Publishers

Introduction. Adequate lymph node evaluation is an important determinant of prognosis in patients with colorectal cancer. Current guidelines recommend evaluation of at least 12 lymph nodes; however, a significant number of patients fail to meet these criteria. Aim. To investigate the factors that influence adequate recovery and evaluation of lymph nodes in colorectal cancer Methods. We retrospectively analyzed 454 consecutive cases of colorectal cancer surgically treated from September 2000 to September 2006. Univariate and multivariate linear and logistic regression analysis was used to study the effect of various factors in lymph node recovery. Results. The number of lymph nodes retrieved ranged from 0 to 62 with a median of 13 nodes. Overall, 189 (41.6%) patients had fewer than 12 nodes removed. Patient age, tumor stage, location and size were associated with lymph node retrieval. Multivariable regression revealed that the aforementioned variables, including gender and hospital type, explained 17% of the observed variance of the lymph node number. Conclusion. Patient and tumor characteristics, although important, are only partly responsible for the variation of lymph node yield. Quality of surgical resection and/or the thoroughness of examination of the tissue by the pathologist might explain the wider proportion of this variance. Training in colorectal node evaluation could help to improve the quality of cancer care. Free full text available at www.tumorionline.it.
