Optimal perioperative treatment for patients requiring segmental colectomy for colon cancer is laparoscopic resection embedded in a FT program. If open surgery is applied, it is preferentially done in FT care. This study was registered under NTR222 (www.trialregister.nl).

Background: PET scans using FDG and somatostatin receptor imaging agents have both been used to study neuroendocrine tumours. Most reports have documented the sensitivity and specificity of each radiopharmaceutical independently, and even suggested the superiority of one over the other for different grades of disease.Aim: The aim of this work was to develop a grading scheme that describes the joint results of both the FDG and somatostatin receptor imaging PET scans in staging subjects with neuroendocrine tumours in a single combined parameter. The grading scheme that has been developed is referred to as the NETPET grade.Methods: This is a retrospective study which assessed subjects who had both FDG and somatostatin receptor PET imaging at our institution within 31 days of each other. The NETPET grade was assigned by experienced nuclear medicine physicians and compared with other clinical data such as WHO grade and overall survival.Results: In the period 2011-2015 we were able to recruit 62 subjects with histologically proven metastatic neuroendocrine tumour for review. The NETPET grade incorporating both the FDG and somatostatin receptor imaging results was significantly correlated with overall survival by univariate analysis (p=0.0018), whereas in this cohort the WHO grade at the time of diagnosis did not correlate with survival.Conclusions: The NETPET grade has promise as a prognostic imaging biomarker in neuroendocrine tumours. It permits the capturing of the complexity of dual radiotracer imaging in a single parameter which describes the subjects' disease and is readily amenable to use in patient management and further research.

LSR was associated with a 15.4% reduction in major complication rates, less pain, improved quality of life, and shorter hospitalization at the cost of a longer operating time.

Objective:The study aims to investigate the prognostic value of the lymphocyte-to-monocyte ratio (LMR) in patients with colorectal cancer (CRC) undergoing curative resection and to compare it to established biomarkers including the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), modified Glasgow prognostic score (mGPS), and combined BRAF-mismatch repair (MMR) status.Background:The prognostic significance of systemic inflammatory markers in CRC such as the NLR, PLR, and mGPS has been well defined. Commonly used genetic markers such as combined BRAF-MMR status have also been found to be prognostic. Recent evidence, although limited, suggests that the preoperative LMR may be prognostic in CRC.Methods:Data from the Northern Sydney Local Health District from January 1998 to December 2012 were retrospectively collected. Of 3281 consecutive patients identified, 1623 patients who underwent curative resection were deemed eligible for inclusion. The relation between the LMR, clinicopathologic variables, and other biomarkers were analyzed in Kaplan-Meier log-rank survival analysis and then multivariate Cox regression models looking for association with overall survival (OS).Results:In multivariate analysis of all patients, elevated LMR was associated with better OS (hazard ratio 0.569, 95% confidence interval: 0.478–0.677, P < 0.001) independent of age (P < 0.001), T stage (P < 0.001), N stage (P < 0.001), and grade (P = 0.049). The NLR, PLR, and combined BRAF-MMR status were not independently significant. In multivariate subgroup analysis of 389 patients with mGPS, LMR remained the only independently significant biomarker (hazard ratio 0.620, 95% confidence interval: 0.437–0.880, P = 0.007).Conclusions:The LMR is an independent predictor of OS in patients with CRC undergoing curative resection and appears to be superior to pre-existing biomarkers.
