RESUMEN

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.

RESUMEN

PURPOSE: Patients with relapsed seminoma after first-line chemotherapy can be treated with salvage chemotherapy or postchemotherapy retroperitoneal lymph node dissection (PC-RPLND). Based on prior experience, surgical management can have worse efficacy and increased morbidity compared to nonseminomatous germ cell tumor. Our aim was to characterize the surgical efficacy and difficulty in highly selected patients with residual disease after first-line chemotherapy. MATERIALS AND METHODS: The Indiana University testis cancer database was queried to identify men who underwent PC-RPLND for seminoma between January 2011 and December 2021. Included patients underwent first-line chemotherapy and had evidence of retroperitoneal disease progression. RESULTS: We identified 889 patients that underwent PC-RPLND, of which only 14 patients were operated on for seminoma. One patient was excluded for lack of follow-up. Out of 13 patients, only 3 patients were disease free with surgery only. Median follow up time was 29.9 months (interquartile ranges : 22.6-53.7). Two patients died of disease. The remaining 8 patients were treated successfully with salvage chemotherapy. During PC-RPLND, 4 patients required nephrectomy, 1 patient required an aortic graft, 2 patients required a partial ureterectomy, and 3 patients required partial or complete caval resection. CONCLUSION: The decision between salvage chemotherapy and PC-RPLND as second-line therapy can be challenging. Salvage chemotherapy is effective but is associated with short and long-term morbidity. Surgical efficacy in this setting seems to be limited, but careful selection of patients may lead to surgical success without affecting the ability to receive any systemic salvage therapies if necessary or causing life-threating morbidity.

RESUMEN

BACKGROUND: Late relapse (LR) of germ cell tumor (GCT) is defined as relapsed disease >2 years from initial treatment. LR remains a challenge both for optimal screening methods and management. We report the method of detection, treatments received, and outcomes in patients with chemotherapy-exposed vs chemotherapy-naïve LR GCT. PATIENTS AND METHODS: The Indiana University testicular cancer database was queried identifying 131 patients with LR GCT evaluated at Indiana University from January 2000 to January 2019. Method of detection of LR was recorded along with site, treatment received, and survival outcomes. The cohort was divided into 4 groups according to seminoma versus non-seminoma GCT (NSGCT) and chemotherapy-exposed vs chemotherapy-naïve LR. Progression-free survival (PFS) and overall survival (OS) were analyzed using the Kaplan-Meier method and compared using the log-rank test. Medians with 95% confidence intervals were also calculated along with the 2-year probabilities. RESULTS: Median age at LR was 38.3 (range, 19.3-56.8). Chemotherapy-exposed accounted for 75 (57%) and chemotherapy-naïve for 56 (43%) of cases. The 2-year OS comparing chemotherapy-exposed versus chemotherapy-naïve was 78.2% versus 100% (P = .0003). For the 72 chemo-exposed NSGCT LR pts, 2-year PFS based on treatment: surgery vs chemotherapy versus surgery + chemotherapy was 67.1% versus 0% versus 47.1% (P < 0.0001). Fifty-nine percent of chemotherapy-exposed LR had elevation of alpha fetoprotein (AFP) at LR diagnosis. CONCLUSION: GCT pts require lifetime follow-up with annual physical exam and tumor markers. Surgical resection, when feasible, remains the preferred treatment for chemotherapy-exposed LR. Chemotherapy-exposed LR has worse outcomes compared to chemotherapy-naïve LR patients.

RESUMEN

PURPOSE: The long-term toxicities of chemotherapy and radiotherapy can represent a significant burden to testicular cancer survivors. Retroperitoneal lymph node dissection (RPLND) is an established treatment for testicular germ cell tumors with minimal late morbidity although little data exist on its efficacy in early metastatic seminoma. Surgery in early metastatic seminoma is a prospective phase II single-arm, multi-institutional trial of RPLND as first-line treatment for testicular seminoma with clinically low-volume retroperitoneal lymphadenopathy. PATIENTS AND METHODS: Twelve sites in the United States and Canada prospectively enrolled adult patients with testicular seminoma and isolated retroperitoneal lymphadenopathy (1-3 cm). Open RPLND was performed by certified surgeons with a primary end point of 2-year recurrence-free survival (RFS). Complication rates, pathologic up/downstaging, recurrence patterns, adjuvant therapies, and treatment-free survival were assessed. RESULTS: A total of 55 patients were enrolled, with a median (IQR) largest clinical lymph node size of 1.6 cm (1.3-1.9). RPLND pathology demonstrated a median (IQR) largest lymph node size of 2.3 cm (0.9-3.5); nine patients (16%) were pN0, 12 (22%) pN1, 31 (56%) pN2, and 3 (5%) pN3. One patient received adjuvant chemotherapy. With a median (IQR) follow-up of 33 months (12.0-61.6), 12 patients experienced recurrence, with a 2-year RFS of 81% and a recurrence rate of 22%. Of the patients who experienced recurrence, 10 were treated with chemotherapy and two underwent additional surgery. At last follow-up, all patients who experienced a recurrence were disease-free and the 2-year overall survival was 100%. Four patients (7%) experienced short-term complications, and four patients experienced long-term complications including incisional hernia (1) and anejaculation (3). CONCLUSION: RPLND is a treatment option for testicular seminoma with clinically low-volume retroperitoneal lymphadenopathy and is associated with low long-term morbidity.

RESUMEN

PURPOSE: On the basis of National Comprehensive Cancer Network guidelines, clinical stage (CS) II seminoma is treated with radiotherapy or chemotherapy. Primary retroperitoneal lymph node dissection (RPLND) demonstrated recent success as first-line therapy for RP-only disease. Our aim was to confirm surgical efficacy and evaluate recurrences after primary RPLND for CS IIA/IIB seminoma to determine if various clinical factors could predict recurrences. PATIENTS AND METHODS: Patients who underwent primary RPLND for seminoma from 2014 to 2021 were identified. All patients had at least 6 months of follow-up. Nineteen patients were part of a clinical trial. Patients receiving adjuvant chemotherapy were excluded from Kaplan-Meier recurrence-free survival (RFS) analysis. RESULTS: We identified 67 patients who underwent RPLND for RP-only seminoma. One patient had pN0 disease. Median follow-up time after RPLND was 22.4 months (interquartile range, 12.3-36.1 months) and 11 patients were found to have a recurrence. The 2-year RFS for RPLND-only patients without adjuvant chemotherapy was 80.2%. Patients who developed RP disease for a period > 12 months had the lowest chance of recurrence, with a 2-year RFS of 92.2%. Seven initial CS II patients were on surveillance for 3-12 months before surgery and no patients experienced recurrence. Pathologic nodal stage and high-risk factors such as tumor size > 4 cm or rete testis invasion of the orchiectomy specimen did not affect recurrence. CONCLUSION: CS II seminoma can be treated with surgery to avoid rigors of chemotherapy or radiotherapy. Patients with delayed development of CS II disease (> 12 months) had the best surgical results. Patients may present with borderline CS II disease, and careful surveillance may avoid overtreatment. Further study on patient selection and extent of dissection remains uncertain and warrants further investigation.

RESUMEN

BACKGROUND: Novel treatments and trial designs remain a high priority for bacillus Calmette-Guerin (BCG)-unresponsive non-muscle-invasive bladder cancer (NMIBC) patients. OBJECTIVE: To evaluate the safety and preliminary efficacy of anti-PD-L1 directed therapy with durvalumab (D), durvalumab plus BCG (D + BCG), and durvalumab plus external beam radiation therapy (D + EBRT). DESIGN, SETTING, AND PARTICIPANTS: A multicenter phase 1 trial was conducted at community and academic sites. INTERVENTION: Patients received 1120 mg of D intravenously every 3 wk for eight cycles. D + BCG patients also received full-dose intravesical BCG weekly for 6 wk with BCG maintenance recommended. D + EBRT patients received concurrent EBRT (6 Gy × 3 in cycle 1 only). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Post-treatment cystoscopy and urine cytology were performed at 3 and 6 -mo, with bladder biopsies required at the 6-mo evaluation. The recommended phase 2 dose (RP2D) for each regimen was the primary endpoint. Secondary endpoints included toxicity profiles and complete response (CR) rates. RESULTS AND LIMITATIONS: Twenty-eight patients were treated in the D (n = 3), D + BCG (n = 13), and D + EBRT (n = 12) cohorts. Full-dose D, full-dose BCG, and 6 Gy fractions × 3 were determined as the RP2Ds. One patient (4%) experienced a grade 3 dose limiting toxicity event of autoimmune hepatitis. The 3-mo CR occurred in 64% of all patients and in 33%, 85%, and 50% within the D, D + BCG, and D + EBRT cohorts, respectively. Twelve-month CRs were achieved in 46% of all patients and in 73% of D + BCG and 33% of D + EBRT patients. CONCLUSIONS: D combined with intravesical BCG or EBRT proved feasible and safe in BCG-unresponsive NMIBC patients. Encouraging preliminary efficacy justifies further study of combination therapy approaches. PATIENT SUMMARY: Durvalumab combination therapy can be safely administered to non-muscle-invasive bladder cancer patients with the goal of increasing durable response rates.

RESUMEN

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. Patients were excluded for elevated preoperative serum tumor markers, receipt of AC, or if pure teratoma or primitive neuroectodermal tumor elements were found in the retroperitoneal pathology. RESULTS: We identified 117 patients with active NSGCT in the retroperitoneum after primary RPLND. We excluded seven patients who lacked meaningful follow-up and 13 patients who received AC. There were 97 patients treated with RPLND alone: 41 pN1, 46 pN2, and 10 pN3. In total, 77 of 97 patients had not recurred after a median follow-up time of 52 months. The 2-year recurrence-free survival (RFS) was 80.3%, and the 5-year RFS was 79%. No differences in RFS were noted among nodal stage-pN1, pN2, and pN3-on Kaplan-Meier analysis. Lymphovascular invasion in the orchiectomy specimen, a high-risk pathologic feature, was also predictive of recurrence after primary RPLND. All 20 patients who recurred were treated with first-line chemotherapy and remained continuously disease free. CONCLUSION: Most men with pathologic stage II disease treated with surgery alone in our series never experienced a recurrence. We did not observe a difference in recurrences between patients with pN1 and pN2. The recommendation for AC for pN2 disease may be overtreatment in most patients.

RESUMEN

PURPOSE: The optimal management of patients with metastatic germ cell tumors who achieve a complete response (CR) after first-line chemotherapy remains unsettled. This study reports long-term outcomes of patients with metastatic germ cell tumor managed with surveillance after achieving a CR to first-line chemotherapy. MATERIALS AND METHODS: Patients with metastatic nonseminomatous germ cell tumor treated at Indiana University between 1990 and 2017 who achieved a CR after first-line chemotherapy and were monitored with surveillance were retrospectively analyzed. CR was defined as normalization of tumor markers AFP and hCG, and no residual mass >1 cm in long axis. Kaplan-Meier methods were used to analyze progression-free survival (PFS) and overall survival (OS). RESULTS: Three hundred sixty-seven patients achieved a CR and were managed with surveillance. After a median followup of 4.97 years, 34 patients had disease progression. At most recent followup, 346 (94%) patients were alive with no evidence of disease, 10 patients (2.7%) died of their disease, 5 (1.4%) died of other causes and 6 (1.6%) were lost to followup. The estimated 2-year PFS was 91% (95% CI: 87%-94%) and 2-year OS was 98% (95% CI: 96%-99%). The estimated 2-year PFS by International Germ Cell Cancer Collaborative Group risk category was 92% for good vs 90% for intermediate vs 87% for poor risk (p=0.15), and the estimated 2-year OS was 99% for good vs 96% for intermediate vs 93% for poor risk disease (p=0.001). CONCLUSIONS: Patients with metastatic nonseminomatous germ cell tumor who achieve a CR after first-line chemotherapy can be observed. Most patients who relapse can be salvaged with surgery and/or chemotherapy.

RESUMEN

OBJECTIVES: To describe the most recent 7 year experience with 137 Indiana pouch patients at a single institution and provide data on complications with this type of urinary diversion during the first postoperative year. METHODS: We queried our bladder cancer database to identify all patients who underwent cystectomy with continent catheterizable urinary reservoir between 2012 and 2018. Pre-, intra-, and postoperative data were collected. Complications were stratified into early (within 90 days) and midterm (90-365 days). The primary outcomes were postoperative complications, and overall and cancer-specific mortality. RESULTS: A total of 137 patients underwent open cystectomy with Indiana pouch creation. Of these, 93% were radical cystectomies. On average, the operation took 422 minutes. There were 53 (39%) patients who experienced any type of complication during the first postoperative year (Clavien II-V). Twenty-five patients (18.2%) readmitted in the early postoperative period vs 18 (13.1%) patients midterm. There were 10 (7.3%) patients that required early reoperation and 11 (8%) in the midterm period. The overall mortality rate was 1.5% early and 3.7% midterm, with the majority of the mortality rate attributed to cancer progression (85.7%). CONCLUSION: Patients undergoing continent catheterizable reservoir urinary diversion appear to have comparable complication rates to other urinary diversions published in the literature. At high-volume urologic institutions, Indiana Pouch creation is a suitable option for select patients desiring a continent diversion.

RESUMEN

PURPOSE: Retroperitoneal lymph node dissection (RPLND) for men with clinical stage (CS) I or II testicular nonseminomatous germ cell tumor (NSGCT) has both staging and therapeutic implications. We aimed to investigate the impact of lymph node count (LNC) on outcome after primary RPLND for men with CS I or II NSGCT using a nationally representative data set. MATERIALS AND METHODS: A retrospective analysis of men who received a primary RPLND for CS I or II NSGCT was performed using the National Cancer Database. The Kaplan-Meier method was used to determine overall survival (OS) according to LNC. Logistic regression analyses were used to identify factors associated with LNC >20 and factors predictive of lymph node-positive (pN+) disease after primary RPLND. RESULTS: Of 1,376 men who comprised our analytical cohort, 50.1% and 49.9% had 1-20 lymph nodes (LNs) and >20 LNs removed, respectively. Five-year OS rates were 96.4% and 99.1% for men with 1-20 and >20 LNs resected, respectively (p=0.004). A higher proportion of men with >20 LNs removed were treated at academic centers, had private insurance, presented with higher AJCC (American Joint Committee on Cancer) CS and were more likely to have pN+ disease, compared to those with 1-20 LNs removed. Factors significantly associated with pN+ disease after RPLND include higher AJCC CS and LNC (per 10-count increase). CONCLUSIONS: Higher LNC after primary RPLND significantly increases the likelihood of identifying pN+ disease and is associated with improved OS. Our data support the therapeutic implications of a thoroughly performed RPLND in the primary setting.

RESUMEN

INTRODUCTION AND OBJECTIVE: The management of severe symptoms secondary to radiation changes to the bladder can be difficult. Many patients often endure costly procedures, hospitalizations, transfusions, and physician visits for intractable symptoms. Our aim was to evaluate the short-term efficacy and feasibility of urinary diversion in patients with severe, debilitating symptoms related to radiation cystitis by focusing on perioperative data examining surgical feasibility and assess for any improvement in the number of procedures, transfusions, hospitalizations, and office visits required. METHODS: With IRB approval, we queried our institutional database for patients with a diagnosis code of radiation cystitis who underwent urinary diversion with or without bladder removal from 2011 to 2018. We reviewed institutional and regional record to assess pre, peri and postoperative outcomes, including rates of surgical procedures, hospitalizations, transfusions and clinic visits, in the year before and after treatment. Non-parametric statistics and linear regression were used. RESULTS: Of the 286 patients with radiation cystitis, 45 patients underwent definitive urinary diversion - 31 with concomitant cystectomy and 14 with diversion alone. Analysis of perioperative variables such as estimated blood loss, surgical time, post-operative hospital stay or complication rates were similar to our experience with cystectomy in non-radiated patients. With a mean follow up of 14.6 months, we found that the number of procedures, hospitalizations and transfusions objectively improved following radical surgery. Office visits, however, did not seem to be impacted by performing urinary diversion. There were no significant differences in post-operative benefits between patients that received a concomitant cystectomy and those that only underwent diversion. CONCLUSION: Patients suffering from severe refractory symptomatic radiation cystitis may be best treated with a radical surgical approach. Definitive urinary diversion with or without cystectomy can lower burden of disease by reducing the need for additional procedures, hospitalizations, and blood transfusions on short term follow-up.

RESUMEN

Squamous cell carcinoma of the penis (SCCP) is uncommon in some countries (including the U.S.), but is an important malignancy elsewhere. As a rare disease, progress has been slow compared to more common tumor types discussed in this anniversary issue and most often limited to single-center or retrospective datasets.  In this section we describe developments leading to the current standard approach with current research questions.

RESUMEN

PURPOSE: Presence of teratoma in the orchiectomy and residual retroperitoneal mass size are known predictors of finding teratoma during postchemotherapy retroperitoneal lymph node dissection (PC-RPLND). We sought to determine if the percentage of teratoma in the orchiectomy specimen could better stratify the risk of teratoma in the retroperitoneum. MATERIALS AND METHODS: The Indiana University Testis Cancer Database was reviewed to identify patients who underwent PC-RPLND for nonseminomatous germ cell tumors from 2010 to 2018. A logistic regression model was fit to predict the presence of retroperitoneal teratoma using teratoma and yolk sac tumor in the orchiectomy, residual mass size and log transformed values of prechemotherapy alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin. The study cohort was split into 60% training and 40% validation sets using 200 bootstraps. A predictive nomogram was developed for predicting teratoma in the retroperitoneum. RESULTS: A total of 422 men were included. Presence of teratoma in the orchiectomy (OR 1.02, p <0.001), residual mass size (OR 1.16, p <0.001) and log transformed prechemotherapy AFP (OR 1.12, p=0.002) were predictive factors for having teratoma in the retroperitoneum. The C-statistic using this model demonstrated a predictive ability of 0.77. Training set C-statistic was 0.78 compared to 0.75 for the validation set. A nomogram was developed to aid in clinical utility. CONCLUSIONS: The model better predicts patients at higher risk for teratoma in the retroperitoneum following chemotherapy, which can aid in a more informed referral for surgical resection.

RESUMEN

OBJECTIVES: To investigate the clinical characteristics and survival outcomes of a large clear cell papillary renal cell carcinoma cohort. METHODS AND MATERIALS: A retrospective review of patients with clear cell papillary renal cell carcinoma at a single academic center was performed after Institutional Review Board approval. Patients underwent either partial or radical nephrectomy from September 2009 to July 2019. Demographic and clinical characteristics, recurrence, and cancer specific and overall survival were reported. RESULTS: A total of 90 patients were included in the study. Median follow up was 26.5 months. Median age was 61 (range 27 to 87). 47.8% of patients were African American. 26.7% of patients had end stage renal disease. 37.8% had multifocal renal tumors. 48.9% underwent partial nephrectomy, while the remainder underwent radical nephrectomy. 43.3% underwent an open surgical approach, 40.0% a robotic approach, and 16.7% a laparoscopic approach. Pathologic stage included T1a (90.0%), T1b (1.1%), and T2b (8.9%). Fuhrman grades 1-3 were present in 18.9%, 77.8%, and 3.3% of patients, respectively. There were no cancer specific deaths. There was one local recurrence and no metastases. The overall survival at a median follow up of 26.5 months was 92.1% (95% confidence interval 83.1%-96.4%). CONCLUSIONS: Clear cell papillary renal cell carcinoma typically presents at a low stage and grade and has favorable survival outcomes. A nephron-sparing approach to treatment should be considered when feasible due to the tumor's indolent nature and propensity towards multifocality.

RESUMEN

OBJECTIVE: To characterize the health-related quality of life reported by patients who received an ileal conduit (IC), Indiana pouch, or neobladder urinary diversion after radical cystectomy. MATERIALS AND METHODS: The Functional Assessment of Cancer Therapy-Vanderbilt Cystectomy Index survey was administered to patients with bladder cancer undergoing radical cystectomy and urinary diversion from 2015-2018. Surveys were completed prior to radical cystectomy and then longitudinally throughout the postoperative course. RESULTS: A total of 146 patients completed questionnaires over a median of 12.3 months, 83 (56.8%) received an IC, 31 (21.2%) an Indiana pouch, and 32 (21.9%) an orthotopic neobladder. There were no significant differences in health related quality of life among urinary diversion groups considering the Trial Outcome Index scores, general overall FACT-G assessment, or total Functional Assessment of Cancer Therapy-Vanderbilt Cystectomy Index instruments. Patients who received IC were older and had higher Charlson Comorbidity Index scores (p <.005) yet still experienced similar improvements in health related quality of life commensurate with the other diversion cohorts. There was a significant difference in physical well-being favoring neobladder over IC or Indiana Pouch urinary diversions (p <.05). CONCLUSIONS: To our knowledge this is the first and largest quality of life analysis comparing all three methods of urinary diversion in a longitudinal fashion utilizing a standardized, validated, treatment-specific health survey. Proper preoperative counseling is critical to ensure understanding of the benefits of available urinary diversion.
