Abstract
PURPOSE OF REVIEW This narrative review provides a comprehensive overview of the evolving role of retroperitoneal lymph node dissection (RPLND) in the management of testicular cancer (TC). It explores the significance of RPLND as both a diagnostic and therapeutic tool, highlighting its contribution to accurate staging, its impact on oncological outcomes, and its influence on subsequent treatment decisions. RECENT FINDINGS RPLND serves as an essential diagnostic procedure, aiding in the precise assessment of lymph node involvement and guiding personalized treatment strategies. It has demonstrated therapeutic value, particularly in patients with specific risk factors and disease stages, contributing to improved oncological outcomes and survival rates. Recent studies have emphasized the importance of meticulous patient selection and nerve-sparing techniques to mitigate complications while optimizing outcomes. Additionally, modern imaging and surgical approaches have expanded the potential applications of RPLND. In the context of TC management, RPLND remains a valuable and evolving tool. Its dual role in staging and therapy underscores its relevance in contemporary urological practice. This review highlights the critical role of RPLND in enhancing patient care and shaping treatment strategies, emphasizing the need for further research to refine patient selection and surgical techniques.

Abstract
Testicular mixed germ cell tumors (TMGCTs) are aggressive neoplasms that often have metastases at the time of diagnosis, primarily in the lungs, bones, and brain. Gastrointestinal metastases are rare, occurring in less than 5% of cases, while duodenal involvement is extremely rare, with only few reported cases. Furthermore, gastrointestinal bleeding is an atypical initial presentation of metastatic TMGCTs. Herein, we present a very rare case of upper gastrointestinal bleeding caused by a duodenal metastasis of a TMGCT in a 24-year-old man. The patient was admitted to our hospital due to abdominal pain and melena with a hemoglobin level of 52 g/L. He had no history of testicular swelling, or any other symptoms or signs of a testicular tumor. Upper gastrointestinal endoscopy revealed a duodenal tumor mass with irregular bleeding, and abdominal ultrasound and computed tomography showed a duodenal mass that infiltrate retroperitoneum. Emergency surgery was performed, and the histopathological findings of the resected specimen were consistent with TMGCT metastasis. Subsequently, a testicular tumor was confirmed and surgically removed; however, multiple metastatic deposits were observed in the lungs. Due to the patient's poor general condition, chemotherapy was not performed. The patient died 3 months after the initial diagnosis. This case suggests that, although duodenal metastatic TMGCTs are rare, they should be considered in the differential diagnosis of gastrointestinal bleeding in young male patients.

Abstract
The staging and surveillance of testicular cancer is a complex topic, which integrates clinical, biochemical, and imaging components. The use of imaging for staging and surveillance of testicular cancer is individually tailored to each patient by considering tumor histology and prognosis. This document discusses the rationale for use of imaging by imaging modality during the initial staging of testicular seminoma and nonseminoma tumors and during the planned surveillance of stage IA and IB testicular cancer by histological subtype integrating clinical suspicion for disease recurrence in surveillance protocols. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Magnetic resonance versus computed tomography for the detection of retroperitoneal lymph node metastasis due to testicular cancer: A systematic literature review. Eur J Radiol Open 2021; 8:100372. [PMID: 34458506 PMCID: PMC8377546 DOI: 10.1016/j.ejro.2021.100372] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 07/27/2021] [Accepted: 08/09/2021] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION It is essential to see if MRI can be used as an alternative to CT for the detection of retroperitoneal lymphadenopathy in patients with testicular neoplasms. By doing so, the amount of radiation received by these young patients might be reduced. MATERIAL AND METHODS A systematic literature review was carried out in 5 databases between January 1984 until December 2020. The articles included were randomized and non-randomized clinical trials, cross-sectional studies, cohort, case and control, and retrospective studies that compare the accuracy of MRI against CT to detect retroperitoneal lymph nodes in patients with testicular neoplasms. RESULTS The search string initially retrieved 222 non duplicated papers from which a total of 3 studies of diagnostic accuracy were included for analysis. These articles evaluated a total of 127 patients with testicular neoplasm; the sample size per study ranged from 25 to 52 patients, with a mean age between 29-34 years. MRI presented a sensitivity ranging from 98-80% and specificity of 100 % when read by an experienced radiologist. However, when it was read by a radiologist with 1 year of experience, the sensitivity dropped to 78 % and specificity to 91%. CONCLUSION This systematic literature review shows a knowledge gap since not much has been published regarding this topic; therefore, randomized clinical trials are mandatory. Research on when to use MRI over CT is necessary to reduce radiation exposure. The authors strongly suggest that readers start researching on this subject.

Unenhanced MRI of the abdomen and pelvis for surveillance of patients with stage 1 testicular cancer post-radical orchiectomy. Abdom Radiol (NY) 2021; 46:1157-1162. [PMID: 32901295 DOI: 10.1007/s00261-020-02715-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 08/11/2020] [Accepted: 08/21/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVE To evaluate the ability of unenhanced magnetic resonance imaging (MRI) to detect metastatic lymphadenopathy in men with stage 1 testicular cancer on surveillance. MATERIALS AND METHODS With IRB approval, we identified 23 consecutive men with stage 1 testicular cancer (diagnosed after orchiectomy) undergoing surveillance with unenhanced MRI of the abdomen and pelvis. Three blinded radiologists (2 inexperienced R1/R2 and 1 experienced R3) independently assessed MRI for: presence, location and size of abnormal lymph nodes and degree of confidence (5-point Likert scale) in diagnosis. Diagnostic accuracy was tabulated and compared between groups using ROC. Inter-observer agreement was assessed using Cohen's kappa statistic. RESULTS 17.4% (4/23) men developed 6 metastatic lymph nodes (reference standard: interval development from baseline, size > 1.0 cm short axis). R1 and R2 detected 75% (3/4) patients with abnormal lymph nodes, compared to R3 who detected all four cases. False positive interpretations occurred in: 5.2% (1/19) R1, 10.5% (2/19) R2 and no patients for R3. Sensitivity, specificity and area under the ROC curve (AUC) were: R1: 75% (95% CI 19.4-99.4%), 94.7% (74.0-99.9%) and 0.85 (0.59-1.00), R2: 75% (19.4-99.4%), 89.5% (66.9-98.7%) and 0.82 (0.57-1.00) and, R3: 100% (95% 39.8-100.0%), 100% (82.4-100%) and 1.00 (1.00-1.00) with no difference in AUC between readers (p = 0.383). Comparison in accuracy between readers is limited due to the small sample size. Inter-observer agreement was substantial (K = 0.62). Median (range) degree of confidence scores were rated: R1 5 (5-5), R2 4 (3-5) and, R3 5 (5-5). CONCLUSION In this study, unenhanced MRI was adequate for surveillance of stage 1 testicular cancer; however, radiologist inexperience may lead to errors.

Abstract
INTRODUCTION Patients with testicular cancer (TC) are mainly young and survival rates are high. MRI has several times been proposed to replace CT in follow-up of this patient group to reduce image-related radiation exposure. However, current evidence is scarce for the use of MRI in this context. AIMS First, to retrospectively evaluate the ability of MRI of the retroperitoneum and pelvis to detect relapse in patients with TC stage I. Second, to present a relevant MRI protocol of the retroperitoneum and pelvis with diffusion weighted imaging (DWI). MATERIAL AND METHODS A retrospective analysis of written radiology reports compared to clinical data from clinical practice from 2010 to 2018. The cohort consists of 2487 MRIs of the retroperitoneum and pelvis in 759 patients with TC stage I (524 seminoma (69.0%), 235 non-seminoma (31.0%)), including 102 patients (13.4%) with confirmed relapse. Confirmed relapse was defined when treatment was initiated for metastatic TC. RESULTS Ninety-five patients had a relapse in the MRI scan field during follow-up. MRI of the retroperitoneum and pelvis showed a high sensitivity of 93.8% and a high specificity of 97.4% for detecting TC relapse. The sensitivity for detecting relapse ≥10 mm in short axis lymph node diameter was 100%. The negative predictive value was 99.7%, the positive predictive value was 59.9% and the accuracy was 97.3%. CONCLUSIONS MRI of the retroperitoneum and pelvis constitutes a safe alternative to CT in follow-up of patients with TC stage I with both a high sensitivity and a high specificity. We present a robust MRI protocol with DWI and estimate that MRI follow-up of TC stage I can be easily implemented in most modern radiology departments.

Abstract
Retroperitoneal lymph node dissection (RPLND) is an important component of the multimodal treatment which cures most patients diagnosed with testicular germ cell tumors. Considering the high cure rates achieved, research focus in recent years has been directed toward improving quality of life and decreasing long-term treatment related sequelae. Consequently, the role of RPLND has evolved over the past 3 decades in both low-stage and advanced testicular cancer. The use of RPLND in clinically stage I and low volume stage II disease may offer the advantages of treating retroperitoneal teratoma which is present in 15% to 20% of patients, avoiding chemotherapy and reducing the need for frequent imaging during follow-up. Similarly, ongoing studies are evaluating the safety and effectiveness of RPLND for the treatment of early stage seminoma to avoid the long-term effects of chemotherapy and radiotherapy. RPLND is traditionally used for the treatment of residual masses >1 cm after completion of chemotherapy. Its role in subcentimeter residual masses remains somewhat controversial given the fact that 25% to 30% of these patients are found to harbor either teratoma or viable nonteratomatous germ cell tumors. The presence of teratoma increases the probability of teratoma in metastatic sites. Modified unilateral templates were developed based on early mapping studies with the aim of preserving antegrade ejaculation. Recent data suggests initial mapping studies underestimated the risk of contralateral retroperitoneal metastases which may reach 32%. Furthermore, antegrade ejaculation may be preserved in >95% of patients undergoing bilateral nerve sparing primary RPLND and >80% undergoing nerve-sparing PC-RPLND, which, in our view is the more prudent oncologic approach. Recently, multiple series have demonstrated the safety and short-term efficacy of minimally invasive RPLND; however, larger studies with prolonged follow-up are required to validate the long-term oncologic efficacy of newer techniques.

Abstract
Testicular ultrasound is typically the first-line imaging examination in evaluating scrotal pathology. However, MR imaging can often provide valuable additional information, especially when ultrasound and/or clinical examinations are inconclusive. This is particularly evident when encountering testicular or paratesticular lesions, where accurate localization and characterization are paramount for management and prognosis. After reviewing normal scrotal anatomy as seen on MR imaging and offering a sample imaging protocol, the article describes specific indications for scrotal MR imaging and highlights imaging findings unique to various benign and malignant causes.

Abstract
Testicular cancer is a rare malignancy mainly affecting young men. Survival for testicular cancer remains high due to the effectiveness of multimodal treatment options. Accurate imaging is imperative to both treatment and follow-up. Both computed tomography (CT) and magnetic resonance imaging (MRI) suffer from size cut-offs as the only distinguishing characteristic of benign vs. malignant lymph nodes and may miss up to 30% of micro-metastatic disease. While functional [positron emission tomography (PET)] imaging may rule out disease in patients with seminoma who have undergone chemotherapy, there is insufficient evidence to recommend its use in other settings. This review highlights the uses and pitfalls of conventional imaging during staging, active surveillance, and post-treatment phases of both seminomatous and non-seminomatous germ cell tumors (NSGCT).

Abstract
The article provides a summary of the epidemiologic and clinical aspects of testicular malignancy. Current standard imaging and novel techniques are reviewed. Present data and clinical treatment trends have favored surveillance protocols over adjuvant radiation or chemotherapy for low-stage testicular malignancy. This has resulted in increasing numbers of imaging studies and the potential for increased long-term exposure risks. Understanding imaging associated risks as well as strategies to minimize these risks is of increasing importance. The development, validation and incorporation of alternative lower risk highly efficacious and cost-effective imaging techniques is essential.

Abstract
Germ cell tumors (GCTs) of the testis are rare, but are the most common cancer in young men. GCTs may consist of one predominant histologic pattern or may represent a mixture of multiple histologic types. For treatment purposes, two broad categories are recognized: 1) pure seminoma and 2) others, which together are termed nonseminomatous GCTs (NSGCTs). In general, seminoma tends to be less aggressive, to be diagnosed at an earlier stage, and to spread predictably along lymphatic channels to the retroperitoneum before spreading hematogenously to the lung or other organs. Compared with NSGCTs, seminoma is exquisitely sensitive to radiation therapy and platinum-based chemotherapy. NSGCTs are usually mixed tumors and teratoma often exists at the sites of metastasis with other GCT elements; cure often requires chemotherapy to kill the chemosensitive-components and surgery to remove the teratomatous components. The main factors contributing to excellent cure rates of GCTs are careful staging at diagnosis; adequate early treatment using chemotherapeutic combinations, with or without radiotherapy and surgery; and very strict follow-up and salvage therapy. We review several clinical studies and summarize the current trends in the management of GCTs.

Abstract
In testicular germ cell tumour (GCT), imaging plays a central role in assessment of tumour bulk, sites of metastases, monitoring response to therapy, surgical planning and accurate assessment of disease at relapse. The primary modality used for imaging patients with GCT is computed tomography (CT) but plain film radiography, ultrasound, magnetic resonance imaging (MRI) and positron emission tomography (PET) may all have roles to play. This article reviews the role of imaging of testicular germ cell tumours.

Abstract
Germ cell cancers of the testis are rare malignancies that occur most commonly in young adult male life. These malignancies are highly curable, and adoption of sophisticated treatment strategies, related to known prognostic-based variables, has resulted in overall cure rates of approximately 95% with acceptable morbidity. These treatment approaches require a thorough knowledge of the underlying pathology and patterns of tumour spread. In recent years a number of prognostic factor-based staging classifications have evolved, each of which can accurately predict prognosis. However, in 1997, an internationally agreed-upon consensus classification applicable to both seminoma and non-seminoma was published. This classification was well validated and has now been incorporated into the TNM and American Joint Committee on Cancer (AJCC) staging systems.

Abstract
Regardless of the treatment option selected for management of low-stage germ cell cancer, ultimate survival is nearly identical. Treatment-related morbidity is very low regardless of management modality and the individual patient can expect similar physical limitations owing to therapy. The overall difference in loss of productivity between treatment programs varies by little more than 1 week. The cost of treatment is similar for all methods, although there is a definite financial advantage to surveillance, less so for selective surveillance, when compared with other forms of management. Socioeconomic factors are of importance when managing limited resources for a large population, but are of less concern to an individual, especially when the mean differences in per patient costs vary by only $5000. Because of these close similarities in efficacy, morbidity, and costs treatment decisions should be individualized. A responsible and reliable patient can be managed safely by selective surveillance. Those individuals considered to be less self-motivated to pursue intensive care should be managed by primary therapy. Without more information regarding the long-term outcomes associated with primary adjuvant chemotherapy, primary adjuvant RPLND, where experienced surgical support is available, is the preferred management for low-stage germ cell cancer in patients selected for, or electing, active treatment rather than surveillance. Active investigations examining the role of medical management in this population should be continued. Our preferred choice of initial management is to offer selective surveillance to appropriate patients and modified RPLND to the remainder.

Abstract
Treatment of testis cancer has improved dramatically over the last 25 years with cure rates that now approach 95%. This success in treatment is the result of multimodal therapy that may include cisplatinum-based chemotherapy, surgery, and radiotherapy. Although there is little dispute that chemotherapy is appropriate as initial treatment for advanced testis cancer, controversy remains regarding the management of early stage B and stage A testis cancer. In part, the current controversy is driven by the performance characteristics of presently available staging methods, that may include serum markers, histologic parameters from orchietomy specimens, and radiographic imaging. This article reviews the performance characteristics and use of these staging methods.

Abstract
The role of Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) in the treatment evaluation of retroperitoneal lymph-node metastases of non-seminomatous testicular tumors (NSTT) was prospectively studied in 10 consecutive patients before, during and after chemotherapy. The results thus obtained were compared with laparotomy findings before and after chemotherapy, the histology of the primary testicular tumor, and that of retroperitoneal residual lesions after chemotherapy. MRI and CT proved to be equivalent in detection and in determining the anatomical localization and size of the retroperitoneal lymph node metastases. Unlike CT, MRI revealed unmistakable changes in the structure of the retroperitoneal lymph-node metastases during chemotherapy, for which no histological cause was found except in mature teratoma. In mature teratoma a high T2 signal was found within the metastases, corresponding with a high water content. On the basis of tumor consistency and signal intensity in the T1- and T2-weighted images, MRI cannot yet warrant any conclusion about the ultimate effect of chemotherapy.

Abstract
The Testicular Cancer Center Intergroup Study entered surgically staged patients with nonseminomatous tumor and metastases limited to the regional lymph nodes into a previously reported cooperative trial of immediate versus delayed therapy for positive retroperitoneal node disease. Patients with negative nodes (stage I) were placed in an observation registry with specified treatment strategy upon relapse. Of 264 stage I cancer patients 27 (10.2%) had recurrence: 5 of these 27 patients died after recurrence of the testicular malignancies, while 4 other nontumor-related deaths have occurred. Pre-lymphadenectomy staging characteristics observed to predict significantly node positivity are the results of radiological examinations, presence of tumor invasion, vascular invasion and tumor histology. In a multiple logistic regression analysis with these variables, misclassification still occurs in more than a fourth of the patients. Future refinements in diagnosis may allow for better prediction of these patients at risk to have positive lymph nodes and ultimately recurrence. Presently, if assessment of nodal involvement is the objective, noninvasive procedures are not an adequate substitute for surgical staging with modified lymphadenectomy.

Abstract
The purpose of this research was to evaluate two sources of error in the performance of computerized tomography (CT) and magnetic resonance imaging (MRI) of the abdomen/pelvis. The sources of error assessed were inter- and intra-observer reliability. Thirty abdomen/pelvis CT scans were randomly selected from each of three hospitals (university, VA, military) with different CT scanners. Two radiologists were recruited from each site to be CT observers. Forty-five abdomen/pelvis MRI scans were randomly selected from two institutions with different MRI scanners. Four observers were recruited to read the MRI scans. All scans were read blind without clinical information or patient identification. Overall inter-observer and intra-observer diagnostic agreement was significantly higher for MRI compared to CT. Inter-observer diagnostic agreement rates were also significantly higher for MRI when the etiologies of neoplastic vascular and metabolic/toxic were assigned. Observer experience in CT (range: 5-9 yr) or MRI (range: 2-4 yr) was not statistically associated with improved diagnostic agreement. This research addresses many of the criticisms of the MRI literature and compares MRI favorably to CT.

Abstract
Magnetic resonance imaging techniques have made it possible to delineate a variety of pathologic processes in the retroperitoneum, including lymphadenopathy, atherosclerotic and aneurysmal disease of the aorta, congenital venous anomalies, and primary and secondary retroperitoneal neoplasms. The availability of multiplanar image display, the excellent soft tissue contrast resolution, and the fact that exogenous contrast materials are not needed are valuable assets of this imaging modality.
