We investigated the incidence and significance of LN in APPF tissue removed during robotic and laparoscopic radical prostatectomy (RP). Patients and Methods: We retrospectively analysed RP performed by a single surgeon from 2013 to 2023. A total of 670 patients underwent RP, with 407 procedures conducted laparoscopically and 263 robotically. Histological results were available for 509 patients, who were examined for the presence of LN and any evidence of metastatic involvement. Results: LN were detected in the periprostatic fat of eighty patients; however, only twelve had lymph node metastasis. Seven of the twelve patients presented with prostate-specific antigen (PSA) levels greater than 10 ng\/mL. All LN-positive patients had a Gleason score of seven or higher. On MRI, all patients had a PIRADS score of four or higher, and eleven were staged at T3 or higher. Additionally, all twelve patients had a Briganti score exceeding twenty. Conclusions: Our series indicates that the APPF contains LN that can harbour metastatic disease. Patients can have LN involved in APPF without the involvement of pelvic LN. Therefore, our study suggests that routine excision of APPF should be considered for appropriate LN staging and to avoid missing any metastasis, and that scoring systems like Briganti should be used to help identify this high-risk group.<\/jats:p>","DOI":"10.3390\/jcm15124614","type":"journal-article","created":{"date-parts":[[2026,6,15]],"date-time":"2026-06-15T08:57:58Z","timestamp":1781513878000},"page":"4614","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Assessment of Presence and Metastatic Involvement of Lymph Nodes in Anterior Periprostatic Fat (APPF) in Prostate Cancer Patients Treated with Robotic and Laparoscopic Radical Prostatectomy"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8940-2310","authenticated-orcid":false,"given":"Mudassir","family":"Wani","sequence":"first","affiliation":[{"name":"Department of Urology, Cardiff and Vale University Health Board, Cardiff CF14 4XW, UK"},{"name":"Faculty of Social and Applied Sciences, Canterbury Christ Church University, Chatham ME4 4UF, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jayasimha","family":"Abbaraju","sequence":"additional","affiliation":[{"name":"Department of Urology & Nephrology, Dartford and Gravesham NHS Trust, Dartford DA2 8DA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bikram","family":"Bhattacharjee","sequence":"additional","affiliation":[{"name":"Department of Radiology, Dartford and Gravesham NHS Trust, Dartford DA2 8DA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdousamad Said","family":"Omar","sequence":"additional","affiliation":[{"name":"Department of Surgery, Aneurin Bevan University Health Board, Newport NP18 3XQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hasan","family":"Al-Chalabi","sequence":"additional","affiliation":[{"name":"Department of Urology, Aneurin Bevan University Health Board, Newport NP18 3XQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4220-5613","authenticated-orcid":false,"given":"Sanjeev","family":"Madaan","sequence":"additional","affiliation":[{"name":"Faculty of Social and Applied Sciences, Canterbury Christ Church University, Chatham ME4 4UF, UK"},{"name":"Department of Urology & Nephrology, Dartford and Gravesham NHS Trust, Dartford DA2 8DA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,14]]},"reference":[{"key":"ref_1","first-page":"209","article-title":"Global Cancer Statistics 2020: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries","volume":"71","author":"Sung","year":"2021","journal-title":"CA Cancer J.
