Tom K Grimsrud

Tom Kristian Grimsrud started at the Cancer Registry in 1994. Tom has a Cand.med. from the University of Oslo in 1980, he later became a specialist in occupational medicine in 1996 and obtained a Ph.D. at the University of Oslo in 2004 on exposure and lung cancer among nickel factory workers. Tom is involved in a number of projects and studies of occupational and environmental cancer. He has been responsible for several completed and ongoing studies on cancer risk with support from the Working Environment Fund in the Confederation of Business, the Norwegian Cancer Society and the Research Council of Norway. He has also contributed/contributes as a supervisor and researcher in studies aimed at cancer among firefighters, talc workers, navy employees and industrial workers.

 

Tom Kristian Grimsrud holds a Cand.med. University of Oslo (1980), is a specialist in occupational medicine (1996), and obtained his PhD from the University of Oslo in 2004 with the thesis "exposure and lung cancer among nickel factory workers".
 
Tom is involved in a number of projects and studies of occupational and environmental cancer. He has been responsible for several completed and ongoing studies of cancer risk among employees in the Norwegian nickel industry (supported by the Working Environment Fund and the Norwegian Cancer Society) and in the Norwegian petroleum industry (among other things supported by the Research Council of Norway).
 
From 2007, he led projects aimed at cancer among employees in the oil industry (refinery workers and offshore employees), projects that are still being continued in new studies. The first large cohort was established (at the Cancer Registry) in 1998, and Grimsrud led the follow-up, which in the first years was financed by the Ministry of Employment and Inclusion and the Research Council of Norway. Research activity among offshore employees has increased, and there are four ongoing projects which, among other things, finance the creation of a new cohort, as well as a research group with several younger researchers. Jo S Stenehjem took over in 2022 for Grimsrud as head of the research group, but Grimsrud still actively participates as co-PI. The research group works closely with the University of Bergen, the University of Oslo, the US National Cancer Institute and the Albert Einstein College of Medicine.
 
Grimsrud has also contributed/contributes as a supervisor and researcher in studies aimed at cancer among firefighters, talc workers, navy employees and industrial workers in a municipality in Nordland county.
 
In collaboration with American researchers, Grimsrud has worked on the risk of glioma (brain tumour), especially studies of reduced risk in allergic conditions (IgE in serum), vitamin D, and cytokines in serum, and increased risk linked to infections (case-control studies in Janus serum bank). The collaboration partners are affiliated with Ohio State University (USA), the Karolinska Institute and the H. Lee Moffitt Cancer Center and Research Institute, Tampa, Florida (USA).
 
Grimsrud also participates in a number of studies that examine the significance for cancer of exposure to chlorinated organic compounds (organochlorines, mainly pesticides and PCBs). The analyzes have been carried out in deep-frozen serum from the Norwegian population in the period 1972–1989 (Janus serum bank), and the studies have taken place under the direction of American researchers, including at the National Cancer Institute and the University of North Carolina.
 
Grimsrud has followed the research and preventive measures aimed at tobacco, snuff and new nicotine products, and contributed to summaries of knowledge in collaboration with researchers at the Institute of Public Health.
 
Another of his areas of work has been participation in the annual publication of cancer statistics in the publication Cancer in Norway, and service assignments in the form of information and guidance, both to parts of the healthcare system and to the public, on questions related to cancer risk from various environmental influences (radon , air pollution and other environmental conditions), and in the event of reports of concern about the accumulation of cancer and an increased risk of cancer (cluster problems, clusters).
