Abstract
Retroperitoneal lymph node dissection (RPLND) has been an integral part of a multimodal treatment strategy in testicular cancer. Surgeons, over the last decade, have advanced the understanding of RPLND by adopting perioperative care pathways, innovative biomarkers, surgical techniques, and developing algorithms for managing complications. This review summarizes updates on various aspects including the enhanced recovery after surgery pathway, imaging techniques, surgical approaches, dissection templates, and the management of complications. We conclude that RPLND has undergone significant evolution and refinement in the modern era and will continue to hold a critical role in the care of patients with testicular cancer.

Abstract
PURPOSE OF REVIEW The management of testicular cancer has evolved over time with multimodal therapy. Retroperitoneal lymph node dissection (RPLND), which is a complex and potentially morbid treatment option, remains the mainstay in surgical treatment. This article reviews the surgical template, approach and anatomical considerations with regards to nerve spare in RPLND. RECENT FINDINGS The standard full bilateral RPLND template has evolved over time to include the area between the renal hilum, bifurcation of the common iliac vessels, and the ureters. Morbidity with regards to ejaculatory dysfunction has led to further refinements in this procedure. Advancements in anatomical understanding of the retroperitoneal structures and their relationship to the sympathetic chain and hypogastric plexus has allowed for modification of surgical templates. Further refinements in surgical nerve sparing techniques have improved functional outcomes without sacrificing oncological outcomes. Finally, extraperitoneal access to the retroperitoneum and minimally invasive platforms have been implemented to further reduce morbidity. SUMMARY RPLND requires strict adherence to oncological surgical principles regardless of template, approach and technique. Contemporary evidence shows that outcomes are best for advanced testis cancer patients when managed at high volume tertiary care facilities with surgical expertise and access to multidisciplinary care.

Abstract
Data on robotic retroperitoneal lymph node dissection (R-RPLND) for metastatic testicular germ cell tumours (mTGCTs) are scarce and the use of R-RPLND itself is still under debate. The aim of our study was to evaluate the indications, feasibility and outcomes of R-RPLND, with special emphasis on differences between primary R-RPLND (pR-RPLND) and post-chemotherapeutic R-RPLND (pcR-RPLND) in mTGCTs. We retrospectively analysed the data of patients who underwent R-RPLND for mTGCT between November 2013 and September 2019 in two centres in Germany. Indications, operative technique, intra- and postoperative complications and oncologic outcome were analysed. Twenty-three mTGCT patients underwent R-RPLND (7 pR-RPLND, 16 pcR-RPLND). For pR-RPLND versus pcR-RPLND, median time of surgery was 243 min [interquartile range (IQR) 123-303] versus 359 min (IQR 202-440, p = 0.154) and median blood loss 100 mL (IQR 50-200) versus 275 mL (IQR 100-775, p = 0.018). Intra- and postoperative complications were more frequent in pcR-RPLND (pcR-RPLND: intra/post: 44%/44%; pR-RPLND: intra/post: 0%/29%). However, these were only statistically significant in the case of intraoperative complications (intra: p = 0.036, post: p = 0.579). Intraoperative complications (n = 7), conversions (n = 4) and transfusions (n = 4) occurred in pcR-RPLND patients only. After a median follow-up of 16.3 months (IQR 7.5-35.0) there were no recurrences or deaths. R-RPLND displays a valuable, minimally invasive treatment option in mTGCT. However, R-RPLND is challenging and pcR-RPLND especially bears a considerable risk of complications. This operation should be limited to patients with an easily accessible residual tumour mass and to surgeons experienced in robotic surgery and TGCT treatment.

Abstract
At the Canadian Testis Cancer Workshop, the multidisciplinary management of testis cancer care was discussed. The two-day workshop involved urologists, medical and radiation oncologists, pathologists, radiologists, physician's assistants, residents, fellows, nurses, patients, and patient advocacy group members.This review summarizes the discussion regarding clinical dilemmas in local and regional testis cancer. We present cases that highlight the need for a coordinated approach to individualize care. Overarching themes include the importance of a multidisciplinary approach to testis cancer, willingness to involve a high-volume experienced center, and given that the oncological outcomes are excellent, a reminder that clinical decisions need to prioritize selecting a strategy with the least treatment-related morbidity when safe.

Abstract
BACKGROUND Postchemotherapy retroperitoneal lymph node dissection (pcRPLND) is mandated in patients with nonseminomatous germ cell tumor found to have residual masses after chemotherapy. Performed via the open approach, pcRPLND can incur significant perioperative morbidity. OBJECTIVE To demonstrate the feasibility of robotic pcRPLND (r-pcRPLND) and provide evidence for its selection criteria. DESIGN, SETTING, AND PARTICIPANTS A retrospective search identified 93 patients undergoing pcRPLND between April 2007 and March 2018, comprising 30 r-pcRPLND and 63 open pcRPLND (o-pcRPLND) procedures performed by a single surgeon. INTERVENTION r-pcRPLND and o-pcRPLND. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Baseline clinicopathologic characteristics and intraoperative variables including operating room (OR) time, estimated blood loss (EBL), resection of adjacent organs, and intraoperative consultation with other surgical services were recorded. Hospital length of stay (LOS) and perioperative complications were assessed as per the Clavien-Dindo classification, and oncologic outcomes such as nodal yield, histologic distribution, pathologic staging, time to recurrence, and cancer-specific survival were compared. RESULTS AND LIMITATIONS r-pcRPLND was performed in a well-selected cohort with lower clinical stage (p=0.006), favorable International Germ Cell Cancer Collaborative Group classification (p=0.01), and smaller retroperitoneal mass (p=0.001). o-pcRPLND required more frequent bilateral template dissection (88.9% vs 43.3%; p<0.001), resection of adjacent organs (36.5% vs 10%; p=0.007), consultation with other surgical services (46% vs 2%; p<0.001), and auxiliary procedures (54.0% vs 20%; p=0.003) to achieve complete oncologic control. OR time was similar between the two groups (o-pcRPLND 375min vs r-pcRPLND 388min; p=0.16) and EBL was significantly lower in r-pcRPLND (234 vs 825ml; p<0.001). Median LOS was significantly shorter after r-pcRPLND (2 vs 7d; p<0.001). A total of 31 patients (33%) suffered postoperative complications, of whom 18 (19.4%) had major complications. Nodal yield was similar (o-pcRPLND 23 vs r-pcRPLND 24; p=0.8). The distribution of lesion histology (necrosis/teratoma/GCT) was also similar pcRPLND (o-pcRPLND 25.4%/57.1%/17.4% vs r-pcPLND 33.3%/50%/16.7%; p=0.51). Overall, tumor recurred in 15 patients (16.1%), including three following r-pcRPLND (10%), all outside the operative field. On univariate analysis, surgical approach was not a significant predictor of time to recurrence (p=0.34). One limitation was that antegrade ejaculation was not assessed. CONCLUSIONS With rigorous patient selection, r-pcRPLND can be safely performed and may reduce perioperative morbidity while maintaining oncologic proficiency. PATIENT SUMMARY Resection of residual retroperitoneal mass after chemotherapy in patients with metastatic testicular cancer can be performed safely via a robotic approach. Robotic surgery can reduce the morbidity of the procedure.

Abstract
The surgical management of both early and advanced stage germ cell tumors of the testis remains a complex process of surgical decision making to maximize oncologic control while minimizing morbidity. Over the past 5 decades, the evolution of the surgical template for retroperitoneal lymphadenectomy (RPLND) has resulted in important modifications to achieve these goals. In this review, we will characterize the historical motivating factors that led to the modified template, outline patient and clinical factors in selecting these approaches in both early and advanced stage disease, and briefly discuss future horizons for their implementation.

Abstract
Due to recent advances in medical technologies, cancer has become more curable and chronic, and post-treatment quality of life, including male fertility, has become an important issue. Cancer itself can affect spermatogenesis through complex interactions, and cancer treatment such as surgery, radiotherapy and chemotherapy, all have certain detrimental effects on spermatogenesis. Currently, sperm cryopreservation before cancer treatment is the mainstay of fertility preservation, and is recommended by numerous guidelines. Although fertility preservation should be discussed with all cancer patients before treatment, it still remains underused. Postpubertal patients who are unable to bank sperm may undergo testicular sperm extraction before treatment. For prepubertal boys, there is no clinically established guideline for fertility preservation. Investigations such as spermatogonial stem cell culture are ongoing, and may lead to clinical options for fertility preservation in the future.

Abstract
UNLABELLED What's known on the subject? and What does the study add? Modern surgical techniques have allowed preservation of fertility in most patients after post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND), but some patients still have infertility after surgery. We reviewed our experience treating infertility in 26 men after PC-RPLND. Using a structured clinical pathway we obtained sperm in 81% of men for use in assisted reproduction. OBJECTIVE To evaluate the effectiveness of a clinical pathway on sperm retrieval outcomes in patients presenting with infertility after post-chemotherapy (PC) retroperitoneal lymph node dissection (RPLND). PATIENTS AND METHODS We carried out a retrospective review of patients with advanced testicular cancer, presenting with infertility after PC-RPLND in a large reproductive urology practice. We implemented a clinical pathway where pseudoephedrine was first administered. If this medication failed, electroejaculation (EEJ) and/or testicular sperm extraction (TESE) was carried out. The primary outcome was retrieval of sperm for use in assisted reproduction. RESULTS Four men had retrograde ejaculation, of whom two converted to antegrade ejaculation with medical therapy. In all, 22 patients had failure of emission (FOE) and, of these, no patient converted to antegrade ejaculation with medication. In patients with FOE, sperm was found in 15/20 of those experiencing a successful EEJ. Seven patients underwent TESE for azoospermia on EEJ or no ejaculate on EEJ, three of whom had sperm found on TESE. Sperm was found for assisted reproduction in 81% (21/26) patients. CONCLUSIONS There appears to be no role for the use of pseudoephedrine therapy in patients with FOE after PC-RPLND. The use of a structured clinical pathway may optimize patient care.

Abstract
OBJECTIVES To evaluate the prognostic significance of the total number of lymph nodes obtained at postchemotherapy retroperitoneal lymph node dissection (PC-RPLND). After the multidisciplinary management of metastatic germ cell tumor, approximately 10%-15% of patients with the histologic finding of fibrosis or teratoma will suffer disease recurrence. METHODS Between 1989 and 2006, a total of 628 patients underwent PC-RPLND and were found to have either fibrosis or teratoma. After Institutional Review Board approval, complete clinical and pathologic data were obtained from our prospective testis cancer surgical database. A Cox proportional hazards regression model was constructed to evaluate the association of the total number of lymph nodes obtained at PC-RPLND on disease recurrence. RESULTS On pathologic evaluation, 248 (57%) patients had fibrosis and 184 (43%) patients had teratoma. The median number of lymph nodes resected was 25 (interquartile range, 15-37). On multivariable analysis, increasing postchemotherapy nodal size and decreasing lymph node counts were significant predictors of disease recurrence (P=.01, .04, respectively). For patients with 10 nodes removed, the predicted 2-year relapse free probability was 90%, compared with 97% when 50 nodes were removed. CONCLUSIONS Our data suggest that the total number of lymph nodes removed and analyzed is an independent predictor of disease recurrence after PC-RPLND. This has implications both for the urologist to assure completeness of resection and for the pathologist to meticulously assess the pathologic specimens.

Abstract
The retroperitoneum is the initial metastatic site in 90% of patients with nonseminomatous germ cell tumours (NSGCTs) of the testis. A retroperitoneal lymph node dissection (RPLND) provides accurate staging and effective therapy, minimizes the need for adjuvant chemotherapy in patients with low-volume metastases, and optimizes durable cure rates. We review the rationale for and development of RPLND, focusing specifically on the advantages and limitations of the variable surgical templates. Bilateral RPLND has a long-standing record of maximizing cancer control and minimizing secondary therapy. Both modified templates and prospective nerve-sparing techniques were introduced to optimize rates of antegrade ejaculation. Limited resections as advocated by modified templates are appealing in the setting of primary RPLND but can be associated with a 3-23% risk of residual disease. Modified templates have also been advocated for highly selected patients after chemotherapy but, if applied to all patients undergoing surgery after chemotherapy, will lead to an unacceptably high rate of residual disease, even in patients with small masses after chemotherapy. For patients undergoing primary or post-chemotherapy RPLND, a full bilateral template (with nerve-sparing when appropriate) maximizes cure rates while minimizing ejaculatory morbidity and the subsequent need for chemotherapy.

Abstract
Retroperitoneal lymph node dissection after chemotherapy (PC-RPLND) plays a crucial role in managing patients with advanced germ cell tumours (GCTs). In the last few years improvements in radiographic staging, a better understanding of the role of serum tumour markers, and the introduction of cisplatin-based chemotherapy have all contributed to this surgical therapy. PC-RPLND is necessary when residual radiographic abnormalities are present after chemotherapy. The need for a PC-RPLND in the face of normal findings from computed tomography (CT) is controversial. CT criteria alone are not sufficiently reliable to distinguish viable tumour or teratoma from necrosis. No combination of variables can predict negative retroperitoneal pathology with sufficient accuracy after induction chemotherapy. Unresected teratoma or viable GCT are at least partly chemorefractory and, if untreated, will progress. So completeness of resection is an independent and consistent predictive variable of clinical outcome. In PC-RPLND surgical margins should not be compromised in an attempt to preserve ejaculation, although nerve-sparing dissections are possible in patients with marker normalization after chemotherapy and necrotic tissue in frozen-section histology. In these patients nerve-sparing techniques and the reduction of surgical field to the left- or right-sided template are applicable to preserve antegrade ejaculation and consecutive fertility. The size and location of residual masses coupled with the retroperitoneal desmoplastic reaction make PC-RPLND a technically demanding procedure that should be performed by experienced surgeons in dedicated referral centres.

Abstract
BACKGROUND The anatomical extent of postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) has been discussed controversially for many years. OBJECTIVE To evaluate the necessity of PC-RPLND with modified or radical template resection in patients with advanced nonseminomatous germ-cell tumors (NSGCT) and residual masses following systemic chemotherapy. DESIGN, SETTING, AND PARTICIPANTS The charts of 152 consecutive patients who were treated at two tertiary referral centers were retrospectively reviewed. INTERVENTION All patients underwent PC-RPLND, with 54 and 98 patients undergoing a radical template resection and 98 patients undergoing a modified template resection. Modified template resection was performed if the location of the residual mass corresponded to the primary landing zone of testis cancer and the residual mass measured < or = 5 cm in diameter. In all other cases a full bilateral PC-RPLND was chosen. MEASUREMENTS The following data were analyzed: location of the residual mass, extent of surgery, length of surgery, treatment-associated complications, nerve-sparing approach, adjunctive surgical procedures, postoperative morbidity, duration of hospital stay, early and late complications, relapse rates, cancer-specific survival rates, and overall survival rates. RESULTS AND LIMITATIONS Overall, 84 patients (55.2%) had necrosis/fibrosis, 45 (29.6%) had mature teratoma, and 23 (15.1%) had vital cancer in the surgical specimens. Antegrade ejaculation was preserved in 85% and 25% of patients undergoing modified and bilateral PC-RPLND (p=0.02), respectively. Eight recurrences (5.2%) were observed after a mean follow-up of 39 mo (range 6-105 mo): one patient had an in-field relapse following modified PC-RPLND, and seven patients had recurrences outside the boundaries of full bilateral PC-RPLNDs. The 2-yr disease-free survival rates were 78.6% and 92.8% for bilateral and modified PC-RPLND, respectively. The limitations of this study were a short follow-up, a limited number of patients, and the retrospective nature of the study. CONCLUSIONS Full bilateral PC-RPLND is the standard approach to extensive residual masses. In well-defined masses a modified template PC-RPLND does not interfere with oncologic outcome but decreases treatment-associated morbidity.
