Brief Summary

Aim of the project is to surveil results after extended lymphadenectomy for right sided colon resection for cancer with different operative techniques. Patients operated for right sided colon cancer will be involved. There are different operative methods used in terms of extend of lymphadenectomy and access (open, laparoscopic and robotic assisted) that are already implemented. The Norwegian standard operation contains less extended lymph node dissection. Patients operated by the standard method will serve as control group. Choice of access and extend of lymph node dissection in Norway is dependant on the surgeon and hospital. At Haukeland University Hospital extend and access of surgery are determined by a multidisciplinary team meeting. More radical surgery might result in more complications and the benefit for the patients in terms of oncological result and survival is uncertain. At Haukeland University Hospital, extended lymphadenectomy has been mostly performed by open surgery. During the study phase we will introduce extended lymphadenectomy by laparoscopy and robotassisted surgery. Hypothesis is that more radical surgery performed by minimal invasive surgery will result in equal or better oncological results, and less complications, shorter hospital stay and better quality of life. As method we choose a prospective observational study. All eligible patients with adenocarcinoma of the right colon without another ongoing oncological treatment for other cancers will be included. Patientdata will be prospectively registered in a web-based database. Aim of the study will be to define the optimal extend of lymphadenectomy to achieve the best oncological result. In addition, we will analyse the results dependent on the surgical access (open, laparoscopic or robotic). The assumed difference between the operative methods is small. Therefore, the study is designed and approved as a multicenter registration in order to achieve the necessary statistical power.

Outcome Measures

Primary Outcomes (1)

  • Surgical complications defined by Calvien Dindo II to V

    The primary aim of the project is to compare the impact of surgical radicality on clinical outcomes for right-sided colon cancer. The Clavien Dindo classification is a validated system ranging from I-V.

    From the operation to discharge and readmission within 30 days

Secondary Outcomes (3)

  • Surgical quality described by the specimen quality and number of lymph nodes harvested

    Postoperatively

  • Oncological quality will be measured by overall survival and recurrence

    Postoperatively up to five years

  • Quality of life after surgery measured with the 15D instrument

    2021 to 2024

Study Arms (3)

Access (Open, laparoscopic, robotic)

Outcomes will be analysed for the different groups

Procedure: Surgical access

Extend of lymphadenectomy described by VAS score

The extend of lymphadenectomy achieved will be described by a visual analogue scale (VAS) after the operation

Procedure: Surgical access

Quality of the specimen

The quality of the specimen will be documented postoperatively by a graded classification system

Procedure: Surgical access
