Item Handling and reporting of orchidectomy specimens with testicular cancer: areas of consensus and variation among 25 experts and 225 European pathologists(Wiley, 2015-09) Berney, Daniel M.; Algaba, Ferran; Amin, Mahul; Delahunt, Brett; Compérat, Eva; Epstein, Jonathan I.; Humphrey, Peter; Idrees, Mohammed; Lopez-Beltran, Antonio; Magi-Galluzzi, Cristina; Mikuz, Gregor; Montironi, Rodolfo; Oliva, Esther; Srigley, John; Reuter, Victor E.; Trpkov, Kiril; Ulbright, Thomas M.; Varma, Murali; Verrill, Clare; Young, Robert H.; Zhou, Ming; Egevad, Lars; Department of Pathology and Laboratory Medicine, IU School of MedicineThe handling and reporting of testicular tumours is difficult due to their rarity. METHODS AND RESULTS: A survey developed by the European Network of Uro-Pathology (ENUP) and sent to its members and experts to assess the evaluation of testicular germ cell tumours. Twenty-five experts and 225 ENUP members replied. Areas of disagreement included immaturity in teratomas, reported by 32% of experts but 68% of ENUP. Although the presence of rete testis invasion was reported widely, the distinction between pagetoid and stromal invasion was made by 96% of experts but only 63% of ENUP. Immunohistochemistry was used in more than 50% of cases by 68% of ENUP and 12% of experts. Staging revealed the greatest areas of disagreement. Invasion of the tunica vaginalis without vascular invasion was interpreted as T1 by 52% of experts and 67% of ENUP, but T2 by the remainder. Tumour invading the hilar adipose tissue adjacent to the epididymis without vascular invasion was interpreted as T1: 40% of experts, 43% of ENUP; T2: 36% of experts, 30% of ENUP; and T3: 24% of experts, 27% of ENUP. CONCLUSIONS: There is remarkable consensus in many areas of testicular pathology. Significant areas of disagreement included staging and reporting of histological types, both of which have the potential to impact on therapyItem Oncological Follow-up Strategies for Testicular Germ Cell Tumours: A Narrative Review(Elsevier, 2022-09-07) Kaufmann, Ernest; Antonelli, Luca; Albers, Peter; Cary, Clint; Gillessen Sommer, Silke; Heidenreich, Axel; Oing, Christoph; Oldenburg, Jan; Pierorazio, Phillip Martin; Stephenson, Andrew J.; Fankhauser, Christian Daniel; Urology, School of MedicineContext: The aim of this review is to describe the proportion of testicular germ cell tumours (tGCTs) with recurrence, and the timing and anatomical sites of relapse across different disease stages and after different treatment options. We summarise published follow-up protocols and discuss current and future developments to personalise follow-up for patients with tGCT. Evidence acquisition: A systematic literature search was conducted and current guidelines and selected institutional follow-up protocols were reviewed. Evidence synthesis: Of 302 publications, we screened 68 full texts and included 29 studies; 22 of these were retrospective and seven were prospective in nature, contributing data for 20 570 patients. The number of patients included per study ranged from 119 to 2483. We compared the guideline follow-up protocols of the European Society for Medical Oncology, European Association of Urology, National Comprehensive Cancer Network, and American Urological Association, as well as institutional follow-up protocols. The protocols differed in terms of the number, time points, and type of follow-up investigations. Conclusions: Future research should assess how tGCT can be followed to ensure high adherence, define the role of miR-371a-3p microRNA during follow-up, and develop follow-up protocols after curative treatment in the metastatic setting. Patient summary: In this review of follow-up protocols for men with testis cancer, we observed different recommendations and discuss future research areas to improve follow-up for these patients.
