Node harvest
When choosing a suitable technique for regression and classification with multivariate predictor variables, one is often faced with a tradeoff between interpretability and high predictive accuracy. To give a classical example, classification and regression trees are easy to understand and interpret. Tree ensembles like Random Forests provide usually more accurate predictions. Yet tree ensembles...
متن کاملLymph node harvest (LNH) in colorectal cancer; a critical appraisal.
The presence of lymph node metastases (LNM) in colorectal cancer is well recognized as one of the most important prognostic factors for long-term outcome (1, 2, 3). It may also determine patients most likely to benefit from adjuvant chemotherapy (4, 5). There is overwhelming evidence to suggest that increased LNH improves staging. More recently it has become evident that the total number of dis...
متن کاملRobotic Harvest of a Right Gastroepiploic Lymph Node Flap
Lymph node flap (LNF) transfer has proven to be an effective option in the treatment of lymphedema. As a result, much research is presently focused on finding an ideal donor site that results in good clinical outcomes while avoiding iatrogenic lymphedema of the donor area. The omental flap with its lymph nodes based on the right gastroepiploic vessels that has been described for the treatment o...
متن کاملNovel Methods of Lymph Node Evaluation for Predicting the Prognosis of Colorectal Cancer Patients with Inadequate Lymph Node Harvest.
PURPOSE Lymph node metastasis is an important factor for predicting the prognosis of colorectal cancer patients. However, approximately 60% of patients do not receive adequate lymph node evaluation (less than 12 lymph nodes). In this study, we identified a more effective tool for predicting the prognosis of patients who received inadequate lymph node evaluation. MATERIALS AND METHODS The numb...
متن کاملHarvest and Post-harvest Operations
Harvest and post-harvest operations constitute principal constraints to rice production, especially in irrigated systems, because of the larger yield that has to be handled. Post-harvest crop losses of up to 35% have been reported and attributed to inefficiency of manual threshing of rice by small-scale farmers. This leads to poor grain quality and rejection of locally produced rice. The Africa...
