The patient was cancer-free for 6\u2009months, at which point a surveillance positron emission tomography-CT scan showed metabolically active hepatosplenic lesions and mediastinal and bilateral hilar lymph nodes. An endobronchial ultrasound bronchoscopy-guided fine needle aspiration of the mediastinal and hilar lymph nodes revealed non-necrotising granulomas. The workup was negative for bacterial, fungal or mycobacterial infection, cancer or autoimmune disease. Carcinoembryonic antigen and COLVERA (a circulating tumour DNA liquid biopsy test for the detection of recurrent colon cancer) tests were negative. Subsequently the rare diagnosis of a sarcoidosis-like reaction from oxaliplatin-based chemotherapy was made. Repeat imaging after 3\u2009months showed resolution of the hepatosplenic lesions and lymphadenopathy, alike.<\/jats:p>","DOI":"10.1136\/bcr-2019-229548","type":"journal-article","created":{"date-parts":[[2020,9,9]],"date-time":"2020-09-09T03:59:23Z","timestamp":1599623963000},"page":"e229548","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":8,"title":["Oxaliplatin-associated sarcoid-like reaction masquerading as recurrent colon cancer"],"prefix":"10.1136","volume":"13","author":[{"given":"Surya Kiran","family":"Aedma","sequence":"first","affiliation":[{"name":"Internal Medicine, Carle Foundation Hospital, Urbana, Illinois, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anusha","family":"Chidharla","sequence":"additional","affiliation":[{"name":"Internal Medicine, University of Illinois College of Medicine at Peoria, Peoria, Illinois, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Kelting","sequence":"additional","affiliation":[{"name":"Medical Oncology, University of Kansas Medical Center, Kansas City, Kansas, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4305-5701","authenticated-orcid":false,"given":"Anup","family":"Kasi","sequence":"additional","affiliation":[{"name":"Medical Oncology, University of Kansas Medical Center, Kansas City, Kansas, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,9,8]]},"reference":[{"key":"2025082712025649000_13.9.e229548.1","doi-asserted-by":"crossref","first-page":"229-37","DOI":"10.1200\/JCO.2004.05.113","article-title":"Folfiri followed by FOLFOX6 or the reverse sequence in advanced colorectal cancer: a randomized GERCOR study","volume":"22","author":"Tournigand","year":"2004","journal-title":"J Clin Oncol"},{"key":"2025082712025649000_13.9.e229548.2","doi-asserted-by":"crossref","unstructured":"Axel Grothey DS .
