Primary Retroperitoneal Lymph Node Dissection for Patients With Pathologic Stage II Nonseminomatous Germ Cell Tumor-N1, N2, and N3 Disease: Is Adjuvant Chemotherapy Necessary?

J Clin Oncol 2022 Jun 8:JCO2200118. Epub 2022 Jun 8.

Department of Urology, Indiana University School of Medicine, Indianapolis, IN.

Purpose: According to National Comprehensive Cancer Network guidelines, adjuvant chemotherapy (AC) has been advocated after primary retroperitoneal lymph node dissection (RPLND) to reduce the risk of relapse in pathologic nodal (pN) stage pN2 or pN3, whereas surveillance is preferred for pN1. We sought to explore the oncologic efficacy of primary RPLND alone for pathologic stage II in nonseminomatous germ cell tumors (NSGCTs) to reduce overtreatment with chemotherapy.

Methods: Patients with pathologic stage II NSGCT after primary RPLND between 2007 and 2017 were identified. Read More

Postchemotherapy retroperitoneal residual mass resection for germ cell testicular tumors: a single-center experience.

Rev Assoc Med Bras (1992) 2022 Apr;68(4):524-529

Ege University Faculty of Medicine, Department of Urology - Izmir, Turkey.

Objective: Postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) plays an important role in the management of advanced germ cell testicular tumors. Bilateral template lymph node dissection is considered a standard treatment in postchemotherapy residual masses; however, modified unilateral templates have gained acceptance in patients with unilateral residual disease. In this study, we aimed to demonstrate the perioperative and oncological outcomes of the patients with advanced testicular cancer who underwent unilateral modified template PC-RPLND in our center.

Performance characteristics of F-fluciclovine positron emission tomography/computed tomography prior to retroperitoneal lymph node dissection.

Can Urol Assoc J 2022 Mar;16(3):E167-E172

Department of Urology, UT Southwestern Medical Center, Dallas, TX, United States.

Introduction: We aimed to determine whether anti-1-amino-3-F-fluorocyclobutane-1-carboxylic acid (F-fluciclovine) positron emission tomography/computed tomography (PET/CT) can accurately detect residual non-seminomatous germ cell tumor (NSGCT) prior to retroperitoneal lymph node dissection (RPLND). There is no reliable way to differentiate between fibrosis/necrosis, teratoma, and viable germ cell tumor in patients receiving post-chemotherapy RPLND. Functional imaging, including F-fludeoxyglucose (18F-FDG) PET/CT, has been disappointing. Read More

Burned-Out Testicular Tumor Presenting as a Retroperitoneal Mass: A Case Report.

Cureus 2022 Jan 25;14(1):e21603. Epub 2022 Jan 25.

Department of Radiation Oncology, Iran University of Medical Sciences, Tehran, IRN.

Spontaneous primary tumor regression, or burned-out tumors, refers to the presence of a metastatic tumor with the histological regression of the primary lesion. The burned-out phenomenon has been reported in various malignancies, with testicular germ cell tumors (GCTs) accounting for a significant share of these cases. However, burned-out testicular tumors are a rare clinical phenomenon and are generally difficult to diagnose, as there is no evidence of primary testicular cancer. Read More
