NCT03776591

Brief Summary

The primary focus in this study is to investigate and improve the surgical technique. In addition the collection of clinical data during diagnostic and follow up and the collection of tumor and blood gives us the opportunity to investigate tumor biology and its relevance in terms of determine appropriate treatment strategy both surgically and oncological and to assess and predict treatment outcome. The aim of this study is to compare short and long-term outcomes between open D3 and laparoscopic CME (complete mesocolic excision) with CVL (central vascular ligation) right colectomy for right-sided colon cancer. Our primary hypothesis is that laparoscopic surgery improves quality of life by reducing pain, postoperative complications and thereby reduces hospital stay and convalescence. On the other hand it is to prove non-inferiority of the laparoscopic group compared to the open group by means of oncological outcome (survival, recurrence). Secondary aim is to evaluate surgical quality by comparing actual vascular stump length between the two groups by postoperative CT and compare number of lymph nodes removed with the specimen. With the use of liquid biopsy we want to detect circulating tumor DNA (ctDNA) and circulating tumor cells (CTCs) and evaluate their value as tumor markers by comparing the prognostic and predictive value. The hypothesis is that ctDNA and CTCs are more sensitive than standard parameters and imaging (CT CEA).
