RESUMEN

BACKGROUND: The management of metastatic renal cell carcinoma (mRCC) has evolved rapidly, and results from the Cancer du Rein Metastatique Nephrectomie et Antiangiogéniques (CARMENA) trial bring into question the utility of cytoreductive nephrectomy (CN). The objective of this study was to examine overall survival (OS) and identify risk factors associated with patients less likely to benefit from CN in the targeted therapy era. METHODS: Patients with mRCC undergoing CN from 2005 to 2017 were identified. Kaplan-Meier methods and Cox proportional hazards regression analyses were used to assess OS and risk-stratify patients, respectively, on the basis of preoperative clinical and laboratory data. RESULTS: Six hundred eight patients were eligible with a median follow-up of 29.4 months. Ninety-five percent of the patients had an Eastern Cooperative Oncology Group performance status less than or equal to 1, and 70% had a single site of metastatic disease. In a multivariable analysis, risk factors significantly associated with decreased OS included systemic symptoms at diagnosis, retroperitoneal and supradiaphragmatic lymphadenopathy, bone metastasis, clinical T4 disease, a hemoglobin level less than the lower limit of normal (LLN), a serum albumin level less than the LLN, a serum lactate dehydrogenase level greater than the upper limit of normal, and a neutrophil/lymphocyte ratio greater than or equal to 4. Patients were stratified into 3 risk groups: low (fewer than 2 risk factors), intermediate (2-3 risk factors), and high (more than 3 risk factors). These groups had median OS of 58.9 months (95% confidence interval [CI], 44.3-66.6 months), 30.6 months (95% CI, 27.0-35.0 months), and 19.2 months (95% CI, 13.9-22.6 months), respectively (P < .0001). The median time to postoperative systemic therapy was 45 days (interquartile range, 30-90 days). CONCLUSIONS: Patients with more than 3 risk factors did not seem to benefit from CN. Importantly, OS in this group was equivalent to, if not higher than, OS for patients in the CN plus sunitinib arm of CARMENA, and this raises the possibility that a well-selected population might benefit from CN.

RESUMEN

BACKGROUND: Postchemotherapy retroperitoneal lymphadenectomy (PC-RPLND) is an essential, yet potentially morbid, therapy for the management of patients with advanced germ cell tumors. In the current study, the authors sought to define the complication profile of PC-RPLND using validated grading systems for intraoperative adverse events (iAEs) and early postoperative complications. METHODS: Between 2000 and 2018, all patients who underwent PC-RPLND were analyzed for iAEs and early postoperative complications using the Kaafarani and Clavien-Dindo classifications, respectively. Logistic regression models were conducted to assess patient and tumor factors associated with iAEs and postoperative complications. RESULTS: Of the 453 patients identified, 115 patients (25%) and 252 patients (56%), respectively, experienced an iAE and postoperative complication. Major iAEs (grade ≥3) were observed in 15 patients (3%) and major postoperative complications (grade ≥3) were noted in 80 patients (18%). The most common iAE was vascular injury (112 of 132 events; 85%), which occurred in 92 patients (20%), and the most frequent postoperative complication was ileus, which occurred in 121 patients (27%). Original and postchemotherapy retroperitoneal mass size, nonretroperitoneal metastases, intermediate and/or poor International Germ Cell Cancer Collaborative Group classification, previous RPLND, elevated tumor markers at the time of RPLND, and anticipated adjuvant surgical procedures increased the risk of both iAEs and postoperative complications. Patients who experienced an iAE were significantly more likely to experience a postoperative complication (odds ratio, 2.50; 95% confidence interval, 1.58-3.97 [P < .001]). CONCLUSIONS: In what to the authors' knowledge is the first analysis of PC-RPLND using validated classifications for both iAEs and postoperative complications, advanced disease and surgical complexity significantly increased the risks of major iAEs and postoperative complications. Standardized reporting of adverse perioperative events allows providers and patients to appreciate the consequences of PC-RPLND during counseling and decision making.

RESUMEN

OBJECTIVE: There is very little literature surrounding the prophylactic use of zonisamide in cluster headaches. The study aims to evaluate the effectiveness of zonisamide for prophylaxis of cluster headache in patients with chronic or episodic cluster headache. BACKGROUND: Both chronic and episodic cluster headaches are debilitating disorders which are often refractory to multiple prophylactic medication regimens. There is a scarcity of research in this area, and current prophylactic options for patients are fairly limited, which is troublesome for affected patients. Zonisamide is an established antiepileptic with a multifactorial mechanism of action which has shown to be useful in other headache disorders such as migraine. METHODS: Twenty cluster headache patients, both episodic (n = 12; ICHD 3.1.1) and chronic (n = 8; ICHD 3.1.2), who had been or currently were treated with zonisamide, were retrospectively evaluated. Effectiveness of the medication was assessed and identified as headache remission or a reduction in severity or frequency of cluster headache of greater than 50%. Responder status, side effects, and dosage were recorded. RESULTS: Fourteen (70%) patients responded to zonisamide treatment, while 6 (30%) did not. Recorded effective plasma zonisamide levels ranged from 10.2 to 31.9 µg/mL. Of the 6 non-responders, 2 stopped the medication due to ineffectiveness, while 4 discontinued the medication secondary to intolerable side effects ranging from gastrointestinal upset to malaise. No more serious adverse events occurred. Eight patients total experienced weight loss/anorexia which many perceived as a positive effect; they lost an average of 10.5% of their body weight in the first 6 months of therapy. CONCLUSIONS: Zonisamide appears to be an effective prophylactic treatment for patients with chronic and episodic cluster headache disorders. Further research in this area is clearly warranted.

RESUMEN

Penile squamous cell carcinoma (PSCC) is a rare malignancy with poor outcomes in advanced stages, with dismal response and survival rates using conventional surgical and systemic options. Additionally, the ability to detect and monitor residual disease with current imaging modalities remains difficult. Therefore, advances in multimodal management and disease monitoring are desperately needed. We present a case of advanced PSCC utilizing multimodal management informed by next-generation sequencing and circulating tumor DNA monitoring. These genomic techniques were valuable in guiding management and deserve further evaluation in the management of PSCC and other rare malignancies.

RESUMEN

OBJECTIVES: Immunotherapy (IO) drugs have been increasingly utilized in locally advanced or metastatic clear cell renal cell carcinoma (ccRCC) and urothelial carcinoma of the bladder (UC). Multiple trials have demonstrated clear survival benefit, however, there are often barriers to access for these advanced therapies which has been demonstrated in other non-urologic malignancies. The goal of this study was to assess socioeconomic and demographic factors associated with the receipt of IO for advanced ccRCC and UC. MATERIALS AND METHODS: We queried the National Cancer Database (NCDB) for patients with stage IV ccRCC and UC. The study period was 2015 to 2020 for ccRCC (FDA approval date of IO) and 2017 to 2020 for UC (FDA approval date of broadened indication for IO, initial limited approval in 2016). The primary outcome of interest was receipt of IO therapy using multivariable logistic regression, adjusting for relevant socioeconomic and demographic variables. RESULTS: We identified 15,926 patients with stage IV ccRCC and 10,380 patients with stage IV UC of which 5,419 (34.0%) and 2,231 (21.5%) received IO therapy, respectively. IO utilization increased with each successive year. In both malignancies, treatment at a non-academic facility, education level, income, and insurance were independently associated with IO utilization. For ccRCC, black (OR = 0.77, 95% CI, 0.64-0.93, P = 0.009) and Hispanic race (OR = 0.73, 95% CI, 0.61-0.86, P = 0.006) were each associated with decreased IO utilization but there were no independent associations between race and receipt of IO in patients with UC. CONCLUSIONS: In the era of FDA-approved IO therapy for advanced ccRCC and UC, this national cohort analysis suggests that IO utilization is increasing over time, but significant disparities exist based on income, education, and insurance status in both malignancies. Additionally, patients treated at non-academic facilities were less likely to receive IO therapy for these specific genitourinary malignancies. In ccRCC, additional disparities were seen black and Hispanic races which each were associated with lower odds of IO receipt. Identifying strategies to mitigate these differences and provide equitable access to IO therapy is of imperative need.

RESUMEN

Prolonged ischemic priapism presents a treatment challenge given the difficulty in achieving detumescence and effects on sexual function. To evaluate current practice patterns, an open, web-based multi-institutional survey querying surgeons' experience with and perceived efficacy of tunneling maneuvers (corporoglanular tunneling and penoscrotal decompression), as well as impressions of erectile recovery, was administered to members of societies specializing in male genital surgery. Following distribution, 141 responses were received. Tunneling procedures were the favored first-line surgical intervention in the prolonged setting (99/139, 71.2% tunneling vs. 14/139, 10.1% implant, p < .001). Although respondents were more likely to have performed corporoglanular tunneling than penoscrotal decompression (124/138, 89.9% vs. 86/137, 62.8%, p < .001), penoscrotal decompression was perceived as more effective among those who had performed both (47.3% Very or Extremely Effective for penoscrotal decompression vs. 18.7% for corporoglanular tunneling; p < .001). Many respondents who had performed both tunneling procedures felt that most regained meaningful sexual function after either corporoglanular tunneling or penoscrotal decompression (33/75, 44.0% vs. 33/74, 44.6%, p = .942). While further patient-centered investigation is warranted, this study suggests that penoscrotal decompression may outperform corporoglanular tunneling for prolonged priapism, and that recovery of sexual function may be higher than previously thought after tunneling procedures.

RESUMEN

Testosterone is an archetypal androgenic-anabolic steroid (AAS), while its exogenous administration is considered to be the gold standard for the treatment of male hypogonadism. The benefits are not due to its intrinsic nature alone but are due to the result of its interactions with the androgen receptor (AR). As the management of hypogonadism continues to advance into the modern era, it would be preferable for modern andrologists to have multiple tools at their disposal to influence AR activity. Nandrolone, or 19-nortestosterone, is one such compound. In the following review of the literature, we examine the history, pharmacology, and clinical applications of this medication. We also present the results of our novel pilot study examining the favorable effects of nandrolone on joint pain for hypogonadal men.
