A recent study redefined and modified the pT2 and pT3 stages incorporating the histopathological variables (tumour grade, lymphovascular invasion, perineural invasion) similar to that used in the current AJCC\u20108E pT1 stage tumour subclassification. In this study, we validate and compare this proposed staging with the AJCC staging systems on an external data set.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>\n                      The data set from a previously published study was obtained. pT2 and pT3 stages were reconstructed as per AJCC 7th edition (AJCC\u20107E), AJCC\u20108E and the proposed staging. The staging systems were correlated with nodal metastasis, disease\u2010free survival (DFS), cancer\u2010specific survival (CSS) and overall survival (OS). All systems were compared using receiver operating characteristic (ROC) curves. A total of 281 cases formed the study cohort.

On adjusted analysis, all the staging systems had a significant correlation with DFS, while only AJCC\u20108E and the proposed staging correlated with CSS and OS. On ROC curve analysis, the proposed staging had the highest area under the curve and was the only staging system to statistically correlate with all the outcome variables.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The proposed staging for pT2\/pT3 tumour stages in penile cancer may improve the prognostic and predictive ability.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/his.14575","type":"journal-article","created":{"date-parts":[[2021,9,29]],"date-time":"2021-09-29T12:31:03Z","timestamp":1632918663000},"page":"566-574","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["A comparative study of AJCC and the modified staging system in pT2\/pT3 penile squamous cell carcinoma\u2009\u2013\u2009a validation on an external data set"],"prefix":"10.1111","volume":"80","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1404-7347","authenticated-orcid":false,"given":"Akash P","family":"Sali","sequence":"first","affiliation":[{"name":"Department of Pathology Homi Bhabha Cancer Hospital (A Unit of Tata Memorial Centre) Sangrur India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gagan","family":"Prakash","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology Tata Memorial Hospital Homi Bhabha National Institute Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"St\u00eanio","family":"de C\u00e1ssio Zequi","sequence":"additional","affiliation":[{"name":"Department of Urology AC Camargo Cancer Center S\u00e3o Paulo Brazil"},{"name":"National Institute for Science and Technology in Oncogenomics and Therapeutic Innovation.
