Objective: The aim of this study was to determine the impact of the sentinel lymph node mapping algorithm (SLN-A) on the staging in high-risk endometrial cancer (EC) compared to SLN plus selective lymphadenectomy (S-LND).
Methods: We retrospectively analyzed the database from a multicenter collaboration that included women with high risk features who underwent primary surgical staging.
Results: One-hundred and seventy-one women were identified (171), 66 in the SLN-A and 105 in the S-LND group, respectively. Pelvic LD was performed on 115 patients (67.2%) and aortic dissection was performed in 54/105 of the women in the S-LND group (51%). The 5-year comparison did not show a significant difference in the strategy adopted for nodal staging, regarding disease-free survival (DFS) [HR: 0.82; 95% CI 0.53-1.28; p = 0.390].
Conclusions: In this study focusing on women with EC in the HR groups, we did not find a difference in the 5-year DFS when comparing the SLN-A strategy with S-LND. The SLN strategy did not seem to compromise the prognosis of patients with a higher risk of recurrence.

Purpose: To establish a prognostic model to estimate progression-free survival (PFS) probability in bladder cancer (BCa) patients undergoing partial cystectomy.
Material And Methods: Consecutive patients who underwent partial cystectomy between August 2012 and April 2021 were enrolled. The primary endpoint was PFS during the follow-up.

Objectives: To develop a nomogram based on the radiomics features of tumour and perigastric adipose tissue adjacent to the tumor in dual-layer spectral detector computed tomography (DLCT) for lymph node metastasis (LNM) prediction in gastric cancer (GC).
Methods: A retrospective analysis was conducted on 175 patients with gastric adenocarcinoma. They were divided into training cohort (n = 125) and validation cohort (n = 50).

Objectives: The Scrotal and Penile Imaging Working Group (SPIWG) of the European Society of Urogenital Radiology (ESUR) aimed to formulate recommendations on the imaging modalities and minimal technical requirements for abdominopelvic imaging in the follow-up of adult patients treated for testicular germ-cell tumors (TGCT).
Methods: The SPIWG members performed an extensive literature search, reviewed the current clinical practice, and reached a consensus based on the opinions of experts in the field.
Results: Recurrence in patients treated for TGCT mainly occurs in retroperitoneal lymph nodes (LNs).
