RESUMO

BACKGROUND: Despite mandated insurance coverage since 2006 and robust health infrastructure in urban settings with high concentrations of minority patients, race-based disparities in prostate cancer (PCa) treatment persist in Massachusetts. In this qualitative study, the authors sought to identify factors driving inequities in PCa treatment in Massachusetts. METHODS: Four hospitals offering PCa treatment in Massachusetts were selected using a case-mix approach. Purposive sampling was used to conduct semistructured interviews with hospital stakeholders. Additional interviews were conducted with representatives from grassroots organizations providing PCa education. Two study staff coded the interviews to identify major themes and recurrent patterns. RESULTS: Of the 35 informants invited, 25 participated in the study. Although national disparities in PCa outcomes were readily discussed, one half of the informants were unaware that PCa disparities existed in Massachusetts. Informants and grassroots organization representatives acknowledged that patients with PCa are willing to face transportation barriers to receive treatment from trusted and accommodating institutions. Except for chief equity officers, most health care providers lacked knowledge on accessing or using metrics regarding racial disparities in cancer outcomes. Although community outreach was recognized as a potential strategy to reduce treatment disparities and engender trust, informants were often unable to provide a clear implementation plan. CONCLUSIONS: This statewide qualitative study builds on existing quantitative data on the nature and extent of disparities. It highlights knowledge gaps in recognizing and addressing racial disparities in PCa treatment in Massachusetts. Improved provider awareness, the use of disparity metrics, and strategic community engagement may ensure equitable access to PCa treatment. PLAIN LANGUAGE SUMMARY: Despite mandated insurance and urban health care access, racial disparities in prostate cancer treatment persist in Massachusetts. This qualitative study revealed that, although national disparities were acknowledged, awareness about local disparities are lacking. Stakeholders highlighted the importance of ancillary services, including translators, rideshares, and navigators, in the delivery of care. In addition, whereas hospital stakeholders were aware of collected equity outcomes, they were unsure whether and who is monitoring equity metrics. Furthermore, stakeholders agreed that community outreach showed promise in ensuring equitable access to prostate cancer treatment. Nevertheless, most interviewed stakeholders lacked clear implementation plans.

RESUMO

In patients with prostate cancer, the duration of remission after treatment with androgen deprivation therapies (ADTs) varies dramatically. Clinical experience has demonstrated difficulties in predicting individual risk for progression due to chemoresistance. Drug combinations that inhibit androgen biosynthesis (e.g., abiraterone acetate) and androgen signaling (e.g., enzalutamide or apalutamide) have proven so effective that new forms of ADT resistance are emerging. In particular, prostate cancers with a neuroendocrine transcriptional signature, which demonstrate greater plasticity, and potentially, increased predisposition to metastasize, are becoming more prevalent. Notably, these subtypes had in fact been relatively rare before the widespread success of novel ADT regimens. Therefore, better understanding of these resistance mechanisms and potential alternative treatments are necessary to improve progression-free survival for patients treated with ADT. Targeting the bromodomain and extra-terminal (BET) protein family, specifically BRD4, with newer investigational agents may represent one such option. Several families of chromatin modifiers appear to be involved in ADT resistance and targeting these pathways could also offer novel approaches. However, the limited transcriptional and genomic information on ADT resistance mechanisms, and a serious lack of patient diversity in clinical trials, demand profiling of a much broader clinical and demographic range of patients, before robust conclusions can be drawn and a clear direction established.

RESUMO

OBJECTIVES: To examine the effects of racial residential segregation and structural racism on the diagnosis, treatment, and outcomes of patients with prostate cancer. PATIENTS AND METHODS: This retrospective cohort study examined men diagnosed with prostate cancer between 2005 and 2015. We collected data from Black and White men, aged ≥30 years, living within the 100 most populous counties participating in the Surveillance, Epidemiology, and End Results programme, a nationally representative dataset. The racial Index of Dissimilarity, a validated measure of segregation, was the primary exposure of interest. Outcomes of interest included advanced stage at diagnosis (Stage IV), surgery for localised disease (Stage I-II), and 10-year overall and cancer-specific survival. Multivariable Poisson regression analyses with robust error variance estimated the relative risk (RR) of advanced stage at diagnosis and surgery for localised disease at differing levels of segregation. Survival analysis was performed using competing hazards analysis. RESULTS: Multivariable models estimating stage at diagnosis showed that the disparities between Black and White men disappeared at low levels of segregation. Disparities in receiving surgery for localised disease persisted across all levels of segregation. In racially stratified analyses, segregation had no effect on stage at diagnosis or surgical resection for Black patients. White patients saw a 56% (RR 0.42, P < 0.001) reduced risk of presenting at advanced stage and 20% increased likelihood (RR 1.20, P < 0.001) of surgery for localised disease. Black patients in the lowest segregation areas had the lowest overall mortality, but the highest cancer-specific mortality. CONCLUSIONS: Our study provides evidence that residential segregation has a significant impact on Black-White disparities in prostate cancer, likely through improved outcomes for White patients and worse outcomes for Black patients in more segregated areas. These findings suggest that mitigating segregation and the downstream effects of socioeconomic factors could alleviate these disparities.

RESUMO

INTRODUCTION: We surveyed U.S. urology trainees to determine current prescribing practices after common endourological procedures. METHODS: An institutional review board approved, 22-item survey was distributed to all U.S. urology residents through the Society of Academic Urologists. The survey was divided into demographics including American Urological Association section, prescribing patterns after ureteroscopy, shockwave lithotripsy, percutaneous nephrolithotomy and transurethral prostate procedures, as well as attitudes surrounding opioid prescription. RESULTS: A total of 148 U.S. urology residents completed the survey (response rate 13%). All American Urological Association sections were represented, including Northeastern (12.8%), New England (8.1%), New York (6.1%), Mid-Atlantic (3.4%), Southeastern (19.6%), North Central (29.05%), South Central (10.1%) and Western (10.8%). By procedure, 72.3% of respondents prescribe opioids after ureteroscopy, 37.8% after shockwave lithotripsy, 93.9% after percutaneous nephrolithotomy, and 53.4% after transurethral prostate procedures. By procedure, the average number of tablets prescribed, were 7.5 (range 0-30) for ureteroscopy, 4.2 (0-20) for shockwave lithotripsy, 14.1 (0-40) for percutaneous nephrolithotomy and 6.7 (0-30) for transurethral prostate procedures. The average number of tablets prescribed by region varied significantly for ureteroscopy, percutaneous nephrolithotomy and transurethral prostate procedures (all p <0.0001), but did not vary significantly for shockwave lithotripsy (p=0.067). CONCLUSIONS: Opioid prescribing practices among U.S. urology residents for common urological procedures varied by regional American Urological Association section, and attitudes surrounding opioid dispensing influenced prescription patterns. While attitudes regarding opioid prescriptions after urological surgery are improving, residents may benefit from additional training, best practice policies and/or society guidelines.

RESUMO

Testicular torsion is a known cause of morbidity in pediatric patients, but the burden in the adult population is poorly understood. We sought to determine the incidence of testicular torsion and risk factors for orchiectomy in a population encompassing all ages. A cohort analysis of 1625 males undergoing surgery for torsion was performed using the 2011 and 2012 Healthcare Cost and Utilization Project Nationwide Emergency Departments Sample. Patient and hospital factors were examined for association with orchiectomy vs. testicular salvage. The estimated yearly incidence of testicular torsion was 5.9 per 100,000 males ages 1-17 years and 1.3 per 100,000 males ≥18 years. Among those undergoing surgical intervention, orchiectomy was performed in 33.6%. The risk of orchiectomy was highest in patients 1-11 years of age and patients over 50 years of age (46.0% and 69.7% of patients, respectively). Orchiectomy was also associated with public insurance (Medicaid/Medicare) or self-pay as primary payer. While testicular torsion is less common in the adult population, the rate of orchiectomy is high. Those with disadvantaged payer status are also at increased risk for testicular loss.

RESUMO

ABSTRACT Objective: Cystectomy with urinary diversion is the gold standard for muscle invasive bladder cancer. It also may be performed as part of pelvic exenteration for non-urologic malignancy, neurogenic bladder dysfunction, and chronic conditions that result in a non-functional bladder (e.g., interstitial cystitis, radiation cystitis). Our objective is to describe the surgical technique of urinary diversion using large intestine as a conduit whilst creating an end colostomy, thereby avoiding a primary bowel anastomosis and to show its applicability with respect to urologic conditions. Materials and Methods: We retrospectively reviewed five cases from a single institution that utilized the described method of urinary diversion with large intestine. We describe operative times, hospital length of stay (LOS), and describe post-operative complications. Results: Five patients with a variety of urologic and oncologic pathology underwent the described procedures. Their operative times ranged from 5 hours to 11 hours and one patient experienced a Clavien III complication. Conclusion: We describe five patients who underwent this procedure for various medical indications, and describe their outcomes, and believe dual diversion of urinary and gastrointestinal systems with colon as a urinary conduit to be an excellent surgical option for the appropriate surgical candidate.

RESUMO

INTRODUCTION: This study aims to compare outcomes of percutaneous nephrolithotomy (PCNL) performed with a nephrostomy tube placed prior to surgery versus access at the time of surgery. MATERIALS AND METHODS: Between March 2005 and August 2014, 233 PCNLs were performed. One hundred and nine of those cases underwent placement of nephrostomy tubes at least 1 day prior to surgery (Group A), and the remaining 124 cases were performed in which access was obtained at the time of PCNL (Group B). Patient demographics, comorbidities, stone size, sepsis rates, and additional complication rates including bleeding and inability to access stone were compared. RESULTS: There were no significant differences in patient demographics, stone size, or comorbidities when comparing the two groups. Success rates were not significantly different, 92.7% in Group A compared to 94.4% in Group B. Similarly, there was no significant difference in complication rates or ICU admissions. The rate of sepsis in Group A was 1.83% compared to 2.42% in Group B, which showed no statistical significance. Notably, there were more patients with neurogenic bladders in the pre-placement group (p = 0.05). CONCLUSION: Pre-placement of a nephrostomy tube prior to PCNL did not result in a decreased incidence of complications or sepsis and did not demonstrate increased success rates. Patients with neurogenic bladders may be more vulnerable to suffering from sepsis and therefore role of timing of nephrostomy tube placement must be further studied.

RESUMO

Urologic tumors invading the inferior vena cava can be a difficult management problem. They are traditionally dealt with utilizing hypothermic circulatory arrest through central cannulation for cardiopulmonary bypass performed through a median sternotomy in addition to the large abdominal incision for the kidney tumor. We describe a single incision approach utilizing normothermic cardiopulmonary bypass to address this technical challenge.

RESUMO

Although open radical cystectomy (ORC) remains the gold-standard management of muscle-invasive bladder cancer, the number of centers performing robotic-assisted radical cystectomy (RARC) has recently increased, prompting greater oncological outcome concerns. Although limited in patient number and follow-up, short-term RARC data from centers of excellence appear to show the approach to be safe and effective, with improved perioperative and functional outcomes, while maintaining comparable oncologic efficiency. Nevertheless, despite the surge of centers adopting RARC, the long-term effectiveness of minimally-invasive techniques has yet to be proven. This review of published RARC series affirms the need for prospective, long-term, controlled studies to adequately evaluate the role of robotics in bladder cancer surgery.

RESUMO

BACKGROUND AND PURPOSE: Obesity is becoming an increasing problem and is associated with increased incidence of renal-cell carcinoma. We sought to assess the impact of obesity on outcomes of laparoscopic partial nephrectomy for renal masses. PATIENTS AND METHODS: We retrospectively reviewed the pathologic and clinical outcomes from January 2004 through August 2010 of consecutive partial nephrectomies that were performed at a single institution. Patients were segregated according to preoperative body mass index (BMI), and outcomes were compared. RESULTS: Seventy-eight nonobese (BMI<30), 24 obese (BMI 30-35), and 24 morbidly obese (BMI>35) patients were identified. Obese patients were significantly more likely to be female (66% >35 vs 32% <30). Other baseline characteristics were similar. There was a significant relationship between estimated blood loss (P=0.03) and increasing BMI when compared as a trend. No significant differences were observed in regard to operative time, transfusion rate, complications, or surgical margin status between groups. CONCLUSION: Laparoscopic partial nephrectomy can be safely performed in obese patients without significant expected difference in outcomes.

RESUMO

BACKGROUND AND PURPOSE: Patients with Gleason (GL) 6 prostate cancer in one or two biopsy cores can be upgraded and/or upstaged at the time of surgery, which may adversely impact long-term outcome. A novel model for prediction of adverse pathologic outcomes was developed using preoperative characteristics. PATIENTS AND METHODS: Between 2003 and 2007, 1159 patients underwent robot-assisted radical prostatectomy (RARP) at our institution. GL 6 prostate cancer in one or two biopsy cores was identified in 416 (36%) patients. Logistic regression analyses were used to assess the rate of GL ≥7 and/or extraprostatic extension at RARP. Covariates consisted of age, body mass index (BMI), number of positive cores, greatest percent of cancer in a core (GPC), clinical stage, and preoperative prostate-specific antigen (PSA) level. After backward variable selection, the developed model was internally validated using the area under the curve and subjected to methods of calibration. RESULTS: Respectively, 278 (67%) and 138 (33%) patients had one or two positive biopsy cores. At RARP, 90 (22%) patients were upgraded to GL ≥7 and 37 (9%) had extraprostatic extension. The novel model relied on age, BMI, preoperative PSA level, and GPC for prediction of adverse pathologic outcomes and was 69% accurate. Calibration plot revealed a virtually perfect relationship between predicted and observed probabilities. CONCLUSIONS: In patients with GL 6 prostate cancer in one or two biopsy cores, 25% have more ominous pathology at RARP. The model provides an individual assessment of adverse outcomes at surgery. Consequently, it may be considered when counseling patients regarding their management options.

RESUMO

AIM: To compare outcomes in patients treated with laparoscopic partial nephrectomy (LPN) and laparoscopic radical nephrectomy (LRN) for clinical T1bN0M0 renal masses. MATERIALS AND METHODS: Between 2002 and 2008, 33 and 52 consecutive patients who underwent LPN and LRN, respectively, for clinical stage T1bN0M0 tumors were retrospectively identified from a prospectively maintained database of 450 patients undergoing laparoscopic renal surgery. Perioperative, pathological, and postoperative outcomes were compared. RESULTS: The two groups of patients were similar in age, sex, and body-mass index. Mean radiographic tumor size was smaller (4.8 vs. 5.2 cm, p = 0.04) in the LPN group. Mean operative time (228 vs. 175 minutes, p < 0.0001) and mean estimated blood loss (233 vs. 112 mL, p = 0.003) were higher in the LPN group. Intraoperative complication rates of 15.2% versus 5.7% (p = 0.28) and postoperative complication rates of 24.2% versus 13.5% (p = 0.20) were observed in the LPN and LRN groups, respectively. Overall median follow-up was 15 and 21 months for the LPN and LRN cohorts, respectively. A 12.5% and 29.3% decline in estimated glomerular filtration rate was observed (p = 0.002), and 30.3% compared with 55.7% of patients developed an estimated creatinine clearance (eCrCl) < 60 mL/minutes after treatment (p = 0.04) for LPN and LRN, respectively. There were no differences in pathological stage distribution between the two groups. In the LPN group there were no local or systemic recurrences, and one positive surgical margin was observed. One patient developed metastatic disease in the LRN group. CONCLUSIONS: LPN for T1b renal tumors provides superior intermediate-term preservation of renal function compared with LRN. Continued follow-up of these patients is required to evaluate oncological outcomes.

RESUMO

BACKGROUND AND PURPOSE: Energy-based hemostasis of the prostatic vascular pedicles (PVP) during robot-assisted radical prostatectomy (RARP) may cause collateral thermal injury to adjacent neural tissue and has been shown to negatively impact sexual function recovery. The unique engineering design of the EnSeal(®) (Ethicon, Cincinnati, OH) has been demonstrated to limit collateral thermal tissue damage to <1.0 mm. Use of tissue and instrument cooling before and during device activation may potentially further reduce thermal spread. As such, we sought to evaluate the collateral tissue effects of EnSeal with or without cold saline irrigation (CSI) during PVP control. PATIENTS AND METHODS: The EnSeal Trio device was used for PVP control in 20 consecutive men undergoing bilateral, non-nerve-sparing RARP. Ipsilateral vascular pedicles were randomly selected to EnSeal plus CSI (<4 °C) application to the tissue before and during device activation or EnSeal alone. The primary end point was the distance of thermal injury from the inked margin using both hematoxylin and eosin (H&E) and terminal transferase uridyl nick end-labeling (TUNEL) apoptosis staining. A mean of three measurements was taken for each pedicle. Pathologic analysis was performed by a single, blinded uropathologist. RESULTS: Mean distance of thermal injury from the inked margin using H&E staining was 0.31 mm (range 0.15-0.40 mm) and 0.98 mm (range 0.7-1.2 mm) for the EnSeal plus CSI and EnSeal alone, respectively (P < 0.0001). TUNEL staining also demonstrated lateral tissue damage of 0.39 mm (range 0.2-0.5 mm) and 1.12 mm (range 0.9-1.3 mm), respectively (P < 0.001). No complications related to hemostasis or postoperative bleeding were observed in the study. CONCLUSIONS: The hemostatic properties of EnSeal work effectively when submerged in CSI. Adjacent thermal tissue damage is significantly minimized with the addition of CSI. This may have a beneficial impact on nerve preservation and sexual function outcomes after RARP.

RESUMO

OBJECTIVES: To present outcomes of a contemporary series of patients undergoing radical cystectomy (RC) for bladder cancer after previous treatment for localized cancer of the prostate (CaP). METHODS: A retrospective review of more than 1000 RCs performed for bladder cancer between 1995 and 2008 identified 49 patients previously treated for localized CaP. Patients were stratified according to the type of primary therapy received for CaP: any form of primary or adjuvant radiotherapy (brachytherapy or external beam radiotherapy) versus radical prostatectomy (RP) monotherapy. Perioperative data were analyzed and compared between the 2 groups. RESULTS: Of 49 patients, 40 (82%) underwent primary or adjuvant radiotherapy and 9 (18%) RP alone. Eleven (22%) patients received a continent diversion. Mean estimated blood loss (EBL) and hospital stay were 979 mL and 12 days, respectively. Extravesical disease (≥pT3a) was present in 23 patients (57.5%) in the radiotherapy group and in 2 patients (22%) in the RP group. Ten patients (all in the radiotherapy group) had a positive margin, 9 (90%) of whom had pathologic T4 disease. The overall major perioperative complication rate was 41%. Of the 6 patients with an ONB (all after RP), 4 had severe incontinence. CONCLUSIONS: Patients undergoing RC after previous treatment for localized CaP are at increased risk for perioperative morbidity. Patients should be counseled that orthotopic diversion after RP may be associated with significant incontinence. Extravesical disease is more prevalent in patients treated with previous radiation. We observed a high rate of positive margins associated with pathologic T4 disease in this cohort.

RESUMO

BACKGROUND AND PURPOSE: Angioembolization is often the first-line treatment for patients with renal angiomyolipoma (AML). Regrowth and repeated hemorrhage after embolization, however, remain a concern. Laparoscopic partial nephrectomy (LPN) is the definitive, minimally invasive treatment alternative. We compared the outcomes of LPN in patients who had a diagnosis of AML with patients with other renal tumors. PATIENTS AND METHODS: From a prospective LPN database, we identified patients with a final pathologic diagnosis of AML (group 1). The ability of preoperative imaging to predict AML final pathology results was studied. Surgical and postoperative outcomes in group 1 were compared with the outcomes of the rest of our LPN cohort (group 2). RESULTS: Of 184 LPNs that were performed between 2002 and 2008, 14 (7.6%) patients and 15 renal units had a diagnosis of AML. Two patients underwent concomitant LPN and radiofrequency ablation (RFA) for multiple AML lesions. In group 1, only 33% of the patients had a preoperative diagnosis of AML. There were no significant differences in tumor size, age, preoperative estimated creatinine clearance, body mass index, and comorbidities between the groups. The mean estimated blood loss in groups 1 and 2 was 214 mL and 178 mL, respectively (P = 0.5). The complication rates were similar between the groups. With a median follow-up of 15 months, no AML recurrences or bleeding was observed in group 1. CONCLUSIONS: The results of LPN or RFA, when appropriate, in AML patients are comparable to the results of LPN for other renal tumors. The preoperative imaging studies were a poor predictor of AML in patients who were undergoing LPN.

RESUMO

OBJECTIVE: The objective of this study was to compare the outcomes of patients >or=70 years of age undergoing laparoscopic partial nephrectomy (LPN), laparoscopic radical nephrectomy (LRN), and laparoscopic ablative techniques (LAT) for small renal masses. METHODS: From a prospectively maintained database we identified 19 (LRN), 28 (LPN), and 19 (LAT) patients aged >or=70 who underwent surgery for cT1aN0M0 lesions. Perioperative, surgical, and functional outcomes were compared. RESULTS: The three groups were similar in age, race, body mass index, and estimated creatinine clearance. In the LRN group, mean tumor diameter was larger (3.3 vs. 2.4 cm [LPN] and 2.7 cm [LAT]; p = 0.0005) and there was a higher percentage of central tumors (73.7% vs. 25.0% and 5.3%; p < 0.0005) when compared with the LPN and LAT groups, respectively. Although intraoperative and postoperative complication rates were similar, mean estimated blood loss and operative time were highest in the LPN group (p < 0.05). Moreover, 42.1%, 39.3%, and 42.1% of patients had preoperative stage 3 chronic kidney disease in the LRN, LPN, and LAT groups, respectively. Patients who underwent LRN had a lower follow-up estimated creatinine clearance (43.4 vs. 61.4 mL/min [LPN] and 59.2 [LAT]; p < 0.01) and a higher likelihood of developing stage 3 chronic kidney disease after treatment (100% vs. 25.0% [LPN] vs. 18.2 [LAT]; p < 0.0005). CONCLUSIONS: Impaired renal function is common in elderly patients presenting with renal masses. LPN and LAT provide superior preservation of renal function when compared with LRN in this population. In appropriately selected patients >or=70 years of age presenting with T1a renal lesions, laparoscopic nephron-sparing approaches should be considered.

RESUMO

PURPOSE: To describe genitourinary (GU) toxicity in men with a history of transurethral resection of the prostate (TURP) treated with external beam radiation therapy (EBRT) for prostate cancer. METHODS AND MATERIALS: Seventy-one men with a history of TURP were treated with EBRT for prostate cancer. The median time from TURP to EBRT was 15 months. The median EBRT dose was 70 Gy, and 21 men (30%) received androgen deprivation therapy (ADT). Acute GU toxicity and late GU toxicity were scored by Radiation Therapy Oncology Group criteria and compared with a cohort of 538 men without prior TURP. The median follow-up for men with TURP and men without TURP was 40 months and 50 months, respectively (p = 0.7605). RESULTS: The rate of acute Grade 2 GU toxicity or higher was 41%, and was increased with a history of more than 1 TURP (73% vs. 31%, p = 0.0036). The 4-year rate of freedom from late Grade 3 GU toxicity or higher was 84%, and was decreased with ADT (45% vs. 95% without ADT, p = 0.0024). By last follow-up, maximal GU toxicity tended to resolve (p < 0.0001) and there was no worsening of urinary symptom scores (p = 0.6911). Compared to men without a prior TURP, TURP patients had a lower rate of freedom from late Grade 3 toxicity or higher (84% vs. 96%, p = 0.0483). Multivariate analysis suggested a higher rate of late Grade 3 toxicity or higher with TURP (risk ratio, 2.87; p = 0.0612) and EBRT dose of 74 Gy or greater (risk ratio, 2.26; p = 0.0521). CONCLUSIONS: Men treated for prostate cancer with EBRT after TURP have a higher risk of severe GU toxicity; however, the overall incidence is low, and toxicity tends not to persist.

RESUMO

OBJECTIVES: To review our laparoscopic partial nephrectomy (LPN) experience, examine the evolution of technique, and compare the outcomes between the early and recent experience. The indications and surgical technique of LPN continuously evolve. METHODS: Data for 184 patients who underwent LPN for a tumor between October 2002 and August 2008 was retrieved from a prospective database. Surgical and functional outcomes for the entire cohort were analyzed and the first 50 (group 1) and most recent 50 (group 2) cases were compared. RESULTS: The groups were similar in terms of baseline renal function, body mass index, and comorbidities. The mean tumor size and the proportion of central tumors in groups 1 and 2 were 2.4 vs 3 cm and 12% vs 52%, respectively (P <.003). In group 2 we stopped the use of ureteral catheters and bolster renorrhaphy, and routinely clamped the renal hilum. Mean warm ischemia time in groups 1 and 2 (30 and 27 minute, respectively, P = .3) and the complication rate were similar. Overall, patients with tumors >4 cm had more complications (P = .042). In group 2 the estimated blood loss and hospital stay decreased (243 vs 140 mL, P = .01, 1.4 vs 2.5 days, P <.001). Overall 78% of the tumors were malignant and the positive margin rate was 3%. With a median follow-up of 18 months, no local or distant tumor recurrences were observed. CONCLUSIONS: With growing experience and technical modifications, LPN is now performed for patients with larger and more central tumors. Longer follow-up is necessary to evaluate oncologic outcomes.
