The impact of age on rectal cancer treatment, complications and survival.

Background: The number of older patients with rectal cancer is increasing. Treatment outcome discrepancies persist, despite similar treatment guidelines. To offer the oldest patients optimal individually adjusted care, further knowledge is needed regarding treatment strategy and outcome.

Octogenarian patients with colon cancer - postoperative morbidity and mortality are the major challenges.

Background: Few studies have addressed colon cancer surgery outcomes in an unselected cohort of octogenarian patients. The present study aimed to evaluate the relative survival of octogenarian patients after a major resection of colon cancer with a curative intent.

Methods: All patients diagnosed with colon cancer at Levanger Hospital between 1980 and 2016 were included.

Risk for Acute Myocardial Infarction After Ophthalmologic Procedures.

Background: Preoperative cardiovascular evaluations are frequently done before ambulatory ophthalmologic procedures. However, whether these procedures can trigger an acute myocardial infarction (AMI) is unknown.

Objective: To assess the short-term risk for AMI associated with ophthalmologic procedures.

Completion surgery vs. primary TME for early rectal cancer: a national study.

Purpose: While local excision by transanal endoscopic microsurgery (TEM) or transanal minimally invasive surgery (TAMIS) is an option for low-risk early rectal cancers, inaccuracies in preoperative staging may be revealed only upon histopathological evaluation of the resected specimen, demanding completion surgery (CS) by formal resection. The aim of this study was to evaluate the results of CS in a national cohort.

Method: This was a retrospective analysis of national registry data, identifying and comparing all Norwegian patients who, without prior radiochemotherapy, underwent local excision by TEM or TAMIS and subsequent CS, or a primary total mesorectal excision (pTME), for early rectal cancer during 2000-2017.

Long-term trends in colorectal cancer: incidence, localization, and presentation.

Background: The purpose of this study was to assess trends in incidence and presentation of colorectal cancer (CRC) over a period of 37 years in a stable population in Mid-Norway. Secondarily, we wanted to predict the future burden of CRC in the same catchment area.

Methods: All 2268 patients diagnosed with CRC at Levanger Hospital between 1980 and 2016 were included in this study.
