Dr. Wolchok did not disclose most of his 31 relationships in articles recently published in other journals, including the New England Journal of Medicine, JAMA and Lancet Oncology. Dr. Wolchok has been paid more than $90,000 from major drug companies since 2014, according to a federal database that only includes payments from companies whose products received approval from the Food and Drug Administration. Most of his relationships are with early-stage start-ups.

Dr. Wolchok said he conducted a review of more than 300 articles and decided to submit updated disclosures on some of them “out of an abundance of caution.” Some journals, including Cancer Discovery, “have rejected these updates because they have determined they are not relevant to the subject matter,” Dr. Wolchok said in a statement.

Mr. Morey said that existing disclosures in the other articles, including those published in the New England Journal of Medicine, were appropriate, based on Dr. Wolchok’s interpretation of the journals’ guidelines.

Although medical journals vary in their requirements, many urge researchers to err on the side of revealing a company relationship. One set of guidelines published by the International Committee of Medical Journal Editors advises authors: “You should disclose interactions with ANY entity that could be considered broadly relevant to the work.” As an example, it says for a researcher studying a particular aspect of lung cancer, “you should report all associations with entities pursuing diagnostic or therapeutic strategies in cancer in general.”

Other corrections involved Dr. Michelle Bradbury, who is the head of a research laboratory at Memorial Sloan Kettering and a director in the radiology department. In two corrections published Monday in the journal Chemistry of Materials, Dr. Bradbury and other study authors said that they should have disclosed that two of them, as well as their institutions — Memorial Sloan Kettering and Cornell University — have a financial interest in Elucida Oncology. The original articles were published in 2017.

Dr. Bradbury is a co-founder and serves on the scientific advisory board of Elucida, which is exploring the use of nanoparticles in cancer detection and treatment, a focus of the articles. Another author, Dr. Ulrich Wiesner of Cornell University, is also a company co-founder and a member of its scientific advisory board. (Dr. Wolchok is also on the Elucida scientific advisory board, which he noted in one of his corrections.)
