Therefore, we herein studied the prognostic significance of the presence and location of CD3+, CD8+, and FoxP3+ T lymphocytes in colorectal cancer samples. In the intratumor analysis, our data did not reveal any association between lymphocyte infiltrations with clinical or pathological data. However, in the tumor margins, we found that the presence of high infiltrations of CD3+, CD8+, or FoxP3+ T lymphocytes were associated with TNM stages I-II (p = 0.021, p = 0.022, and p = 0.012, respectively) and absence of lymph node metastases (p = 0.010, p = 0.003, and p = 0.004, respectively). Despite these associations with good prognostic indicators, we were not able to find any statistically significant alterations in the overall survival of the patients, even though high infiltrations of FoxP3+ T lymphocytes in the tumor margins resulted in an increased overall survival of 14 months. Taken together, these data show that the presence of CD3+, CD8+, or FoxP3+T lymphocyte infiltrates in the tumor margins are associated with the pathogenesis of CRC, but only high Foxp3+ T lymphocyte infiltrations in the tumor invasive margins are inclined to indicate favorable prognosis.<\/jats:p>","DOI":"10.3390\/biology10080808","type":"journal-article","created":{"date-parts":[[2021,8,20]],"date-time":"2021-08-20T08:44:45Z","timestamp":1629449085000},"page":"808","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Increased CD3+, CD8+, or FoxP3+ T Lymphocyte Infiltrations Are Associated with the Pathogenesis of Colorectal Cancer but Not with the Overall Survival of Patients"],"prefix":"10.3390","volume":"10","author":[{"given":"Ana Margarida","family":"Barbosa","sequence":"first","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s\u2014PT Government Associate Laboratory, 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3221-0403","authenticated-orcid":false,"given":"Olga","family":"Martinho","sequence":"additional","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s\u2014PT Government Associate Laboratory, 4710-057 Braga, Portugal"}]},{"given":"Rosete","family":"Nogueira","sequence":"additional","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s\u2014PT Government Associate Laboratory, 4710-057 Braga, Portugal"},{"name":"CGC Genetics\/Centro de Gen\u00e9tica Cl\u00ednica-Unilabs\u2014Laboratory of Pathology, 4000-432 Porto, Portugal"}]},{"given":"Juliana","family":"Campos","sequence":"additional","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s\u2014PT Government Associate Laboratory, 4710-057 Braga, Portugal"}]},{"given":"Liliana","family":"Lobo","sequence":"additional","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s\u2014PT Government Associate Laboratory, 4710-057 Braga, Portugal"}]},{"given":"Henrique","family":"Pinto","sequence":"additional","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s\u2014PT Government Associate Laboratory, 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5779-9752","authenticated-orcid":false,"given":"Adhemar","family":"Longatto-Filho","sequence":"additional","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s\u2014PT Government Associate Laboratory, 4710-057 Braga, Portugal"},{"name":"Laboratory of Medical Investigation (LIM) 14, Faculty of Medicine, University of S\u00e3o Paulo, S\u00e3o Paulo 01246-903, Brazil"},{"name":"Molecular Oncology Research Center, Barretos Cancer Hospital, Barretos, S\u00e3o Paulo 14784-400, Brazil"}]},{"given":"Ant\u00f3nio G.","family":"Castro","sequence":"additional","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s\u2014PT Government Associate Laboratory, 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3526-3199","authenticated-orcid":false,"given":"Sandra F.","family":"Martins","sequence":"additional","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s\u2014PT Government Associate Laboratory, 4710-057 Braga, Portugal"},{"name":"Coloproctology Unit, Braga Hospital, 4710-243 Braga, Portugal"}]},{"given":"Eg\u00eddio","family":"Torrado","sequence":"additional","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s\u2014PT Government Associate Laboratory, 4710-057 Braga, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,20]]},"reference":[{"key":"ref_1","first-page":"89","article-title":"Epidemiology of colorectal cancer: Incidence, mortality, survival, and risk factors","volume":"14","author":"Rawla","year":"2019","journal-title":"Prz.
