A contemporary comparison of laparoscopic versus open partial nephrectomy for renal cell carcinoma.

PURPOSE: To analyze surgical and oncologic outcomes of patients undergoing open partial nephrectomy (OPN) versus laparoscopic partial nephrectomy (LPN) for treatment of renal cell carcinoma (RCC). METHODS: We retrospectively investigated our institutional RCC database for patients who underwent PN for RCC from 1997 to 2018. Decision for technique was at the discretion of the operating urologist, following practice patterns and training history. Outcomes analyzed included pre/peri/post-operative parameters, pathologic outcomes, and disease recurrence rates. RESULTS: 1088 patients underwent PN from 1997 to 2018. After exclusionary criteria, 631 patients who underwent 647 unique PNs for a total of 162 OPN and 485 LPN remained. Baseline, pre-op, and pathologic characteristics were not statistically different. Surgical time was lower in laparoscopic cases [185 vs. 205 min] (p = 0.013). Margin involvement was not statistically different; LPN had lower estimated blood loss (EBL) [150 vs. 250 mL] (p < 0.001) and longer ischemia time [21 vs. 19 min] (p = 0.005). LPN had shorter length of stay [2 vs. 4 days] (p < 0.001), fewer overall complications (p < 0.001), and no significant difference in high-grade complications [2.89 vs. 4.32%] (p = 0.379). Fewer LPN patients developed metastases [1.65 vs. 4.94%] (p = 0.0499). Local recurrence rates were not statistically different [1.24 vs. 3.09%] (p = 0.193). Renal function was equivalent between cohorts post-operatively. CONCLUSION: Long-term oncologic outcomes were not significantly different between LPN versus OPN, with no statistical difference in patient and tumor characteristics. LPN was associated with lower EBL, shorter length of stay, and lower overall complication risk. Renal function was not significantly different between cohorts.

Estimated Prostate Volume by Semiautomatic Segmentation of MRI Is More Accurately Correlated with Radical Prostatectomy Specimen Weight than the Volume Calculated by Ellipsoid Formula.

INTRODUCTION: Accurate in vivo prostate volume (PV) estimation is important for obtaining prostate-specific antigen density (PSAD) and further predicting clinically significant prostate cancer (csPCa). We aimed to evaluate the accuracy of multiparametric magnetic resonance imaging (mpMRI)-estimated PV compared to both volume and weight of radical prostatectomy (RP). METHODS: We identified 310 PCa patients who underwent RP following combined targeted and systematic biopsy in our institution from September 2019 to February 2021. The MRI PV was determined using a semiautomated segmentation algorithm. RP PV was calculated using the prolate ellipsoid formula (length × width × height × π/6). Formula (prostate weight = [actual weight-3.8 g]/1.05 g/mL) was applied, and the resulting volume was used in further analysis. RESULTS: The median PV from MRI, RP, and RP weight were 39 mL, 38 mL, and 44 mL, respectively. Spearman's rank correlation coefficients (ρ) were 0.841 (MRI PV vs. RP weight), 0.758 (RP PV vs. RP weight), and 0.707 (MRI PV vs. RP PV) (all p < 0.001). Decreased correlation between the MRI PV and RP PV was observed in the larger (more than 55 mL) prostate. The PSAD derived from MRI PV showed most efficient to detect csPCa in RP specimen (57.9% vs. 57.6% vs. 45.4%). CONCLUSION: MRI PV is correlated better with RP weight than calculated RP PV, especially in larger prostate. The high csPCa detection rate in final pathology suggested that PSAD derived from MRI PV can be confidently used in clinical practice.

Radical cystectomy versus trimodality therapy for muscle-invasive bladder cancer: a multi-institutional propensity score matched and weighted analysis.

BACKGROUND: Previous randomised controlled trials comparing bladder preservation with radical cystectomy for muscle-invasive bladder cancer closed due to insufficient accrual. Given that no further trials are foreseen, we aimed to use propensity scores to compare trimodality therapy (maximal transurethral resection of bladder tumour followed by concurrent chemoradiation) with radical cystectomy. METHODS: This retrospective analysis included 722 patients with clinical stage T2-T4N0M0 muscle-invasive urothelial carcinoma of the bladder (440 underwent radical cystectomy, 282 received trimodality therapy) who would have been eligible for both approaches, treated at three university centres in the USA and Canada between Jan 1, 2005, and Dec 31, 2017. All patients had solitary tumours less than 7 cm, no or unilateral hydronephrosis, and no extensive or multifocal carcinoma in situ. The 440 cases of radical cystectomy represent 29% of all radical cystectomies performed during the study period at the contributing institutions. The primary endpoint was metastasis-free survival. Secondary endpoints included overall survival, cancer-specific survival, and disease-free survival. Differences in survival outcomes by treatment were analysed using propensity scores incorporated in propensity score matching (PSM) using logistic regression and 3:1 matching with replacement and inverse probability treatment weighting (IPTW). FINDINGS: In the PSM analysis, the 3:1 matched cohort comprised 1119 patients (837 radical cystectomy, 282 trimodality therapy). After matching, age (71·4 years [IQR 66·0-77·1] for radical cystectomy vs 71·6 years [64·0-78·9] for trimodality therapy), sex (213 [25%] vs 68 [24%] female; 624 [75%] vs 214 [76%] male), cT2 stage (755 [90%] vs 255 [90%]), presence of hydronephrosis (97 [12%] vs 27 [10%]), and receipt of neoadjuvant or adjuvant chemotherapy (492 [59%] vs 159 [56%]) were similar between groups. Median follow-up was 4·38 years (IQR 1·6-6·7) versus 4·88 years (2·8-7·7), respectively. 5-year metastasis-free survival was 74% (95% CI 70-78) for radical cystectomy and 75% (70-80) for trimodality therapy with IPTW and 74% (70-77) and 74% (68-79) with PSM. There was no difference in metastasis-free survival either with IPTW (subdistribution hazard ratio [SHR] 0·89 [95% CI 0·67-1·20]; p=0·40) or PSM (SHR 0·93 [0·71-1·24]; p=0·64). 5-year cancer-specific survival for radical cystectomy versus trimodality therapy was 81% (95% CI 77-85) versus 84% (79-89) with IPTW and 83% (80-86) versus 85% (80-89) with PSM. 5-year disease-free survival was 73% (95% CI 69-77) versus 74% (69-79) with IPTW and 76% (72-80) versus 76% (71-81) with PSM. There were no differences in cancer-specific survival (IPTW: SHR 0·72 [95% CI 0·50-1·04]; p=0·071; PSM: SHR 0·73 [0·52-1·02]; p=0·057) and disease-free survival (IPTW: SHR 0·87 [0·65-1·16]; p=0·35; PSM: SHR 0·88 [0·67-1·16]; p=0·37) between radical cystectomy and trimodality therapy. Overall survival favoured trimodality therapy (IPTW: 66% [95% CI 61-71] vs 73% [68-78]; hazard ratio [HR] 0·70 [95% CI 0·53-0·92]; p=0·010; PSM: 72% [69-75] vs 77% [72-81]; HR 0·75 [0·58-0·97]; p=0·0078). Outcomes for radical cystectomy and trimodality therapy were not statistically different among centres for cancer-specific survival and metastasis-free survival (p=0·22-0·90). Salvage cystectomy was done in 38 (13%) trimodality therapy patients. Pathological stage in the 440 radical cystectomy patients was pT2 in 124 (28%), pT3-4 in 194 (44%), and 114 (26%) node positive. The median number of nodes removed was 39, the soft tissue positive margin rate was 1% (n=5), and the perioperative mortality rate was 2·5% (n=11). INTERPRETATION: This multi-institutional study provides the best evidence to date showing similar oncological outcomes between radical cystectomy and trimodality therapy for select patients with muscle-invasive bladder cancer. These results support that trimodality therapy, in the setting of multidisciplinary shared decision making, should be offered to all suitable candidates with muscle-invasive bladder cancer and not only to patients with significant comorbidities for whom surgery is not an option.

Impact of an Expanded Definition of Family History on Outcomes of Active Surveillance for Prostate Cancer.

PURPOSE: Despite family history being an established risk factor for prostate cancer, the role of a broader definition of family history inclusive of not just prostate cancer but other genetically related malignancies has not been investigated in the active surveillance population. Here, we evaluate the impact of an expanded definition of family history on active surveillance outcomes. MATERIALS AND METHODS: Patients undergoing active surveillance for prostate cancer at Massachusetts General Hospital from 1997-2019 with detailed data available on family cancer history were identified. Primary outcome was biopsy progression-free survival, and secondary outcomes were treatment-free survival, adverse pathological features at prostatectomy, and biochemical recurrence after treatment. Statistical analyses were conducted using the Kaplan-Meier method and Cox regression. RESULTS: Among 855 evaluable patients, 300 (35.1%) patients had any family history of prostate cancer, and 95 (11.1%) had a family history of related malignancies suggestive of a hereditary cancer syndrome. Family history of prostate cancer alone was not associated with biopsy progression, whereas family history suggestive of a hereditary cancer syndrome was associated with a significantly increased risk of biopsy progression (HR 1.43, 95%CI 1.01-2.02), independent of other known clinicopathological risk factors in multivariable analysis. Similarly, family history suggestive of a hereditary cancer syndrome was associated with significantly lower treatment-free survival (HR 1.58, 95%CI 1.14-2.18) in multivariable analysis. No significant association was found between family history and adverse features on surgical pathology or biochemical recurrence. CONCLUSIONS: An expanded family history suggestive of a hereditary cancer syndrome is an independent predictor of biopsy progression during active surveillance. Men with such a family history may still be offered active surveillance but should be counseled regarding the higher risk of disease progression.

NCCN Guidelines® Insights: Prostate Cancer Early Detection, Version 1.2023.

The NCCN Guidelines for Prostate Cancer Early Detection provide recommendations for individuals with a prostate who opt to participate in an early detection program after receiving the appropriate counseling on the pros and cons. These NCCN Guidelines Insights provide a summary of recent updates to the NCCN Guidelines with regard to the testing protocol, use of multiparametric MRI, and management of negative biopsy results to optimize the detection of clinically significant prostate cancer and minimize the detection of indolent disease.

Outcomes of robotic-assisted pyeloplasty in symptomatic versus asymptomatic patients.

OBJECTIVE: To evaluate the outcome of robotic-assisted laparoscopic pyeloplasty (RAP) in symptomatic patients with ureteropelvic junction obstruction (UPJO) versus patients who were incidentally found to have UPJO. METHODS: We retrospectively reviewed the records of 141 patients who underwent RAP at Massachusetts General Hospital between 2008 and 2020. Patients were categorized into symptomatic group and asymptomatic group. We compared patient demographics as well as preoperative and postoperative symptoms and functional renal scans. RESULTS: The study population included 108 patients in the symptomatic group and 33 patients in the asymptomatic group. Mean age was 46 ± 17 years with average follow-up time of 12 ± 18 months. Asymptomatic patients had significantly higher rate of definite obstruction (80% versus 70%) and equivocal obstruction (10% versus 0.9%) on preop renogram (P: 0.001). There was no significant difference in the preop split renal function in symptomatic versus asymptomatic group (39 ± 13 versus 36 ± 13 P: 0.3). Following RAP, 91% of symptomatic patients achieved symptom resolution, while four asymptomatic patients (12%) developed new symptoms postoperatively. Compared to preoperative renogram, RAP resulted in improvement in renogram indices in 61% of symptomatic versus 75% of asymptomatic patients (P: 0.2). CONCLUSION: Although asymptomatic patients had worse obstructive indices on renogram, both symptomatic and asymptomatic groups had comparable improvement in renal function following robotic pyeloplasty. RAP is a safe and efficacious minimally invasive option to offer symptom resolution in symptomatic patients and improve obstruction in both symptomatic and asymptomatic patients with UPJO.

Transperineal Multiparametric Magnetic Resonance Imaging-Ultrasound Fusion Targeted Prostate Biopsy Combined with Standard Template Improves Prostate Cancer Detection.

PURPOSE: Transperineal (TP) prostate biopsy provides an effective approach to prostate cancer (PCa) detection. Although transrectal targeted biopsy has been well described, the specific advantage of the standard TP template or TP targeted biopsy using multiparametric (mp) magnetic resonance imaging (MRI)-ultrasound (US) fusion remains less understood and without consensus. MATERIALS AND METHODS: We identified all men who underwent a transperineal standard 20-core template in addition to a targeted biopsy with mpMRI-US fusion-guided software from September 2019 to February 2021. We assessed and compared clinical, MRI and biopsy characteristics between standard TP template and fusion targeted biopsies. RESULTS: A total of 301 men underwent TP fusion biopsy during the study period. Target lesions on MRI were sampled with 3 targeted cores per patient (IQR 3-4). The overall cancer detection rate was 74.1% and 63.5% by standard template and targeted biopsy, respectively, of which 52.5% and 59.7% were clinically significant (cs) PCa. Combined csPCa detection rate was 62.2%. Of 176 cases with a cancer diagnosis by both biopsy methods, 18.8% were upgraded with targeted biopsies while 18.2% were upgraded with template biopsies. CONCLUSIONS: In men with suspicious lesions on mpMRI, TP MRI fusion-guided biopsies combined with standard template provide a higher overall cancer detection rate and higher detection rate of csPCa than the standard template or targeted biopsy alone. In the setting of a suspicious mpMRI prostate lesion, targeted plus standard template should be included as part of the TP biopsy procedure.

Complications and Outcomes of Salvage Cystectomy after Trimodality Therapy.

PURPOSE: Salvage cystectomy is required for some patients with intravesical recurrence after trimodality therapy. We compared postoperative outcomes between salvage cystectomy post-trimodality therapy, primary cystectomy and primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy. MATERIALS AND METHODS: We included 265 patients who underwent radical cystectomy at Massachusetts General Hospital for cT1-T4 bladder cancer between 2003 and 2013. Patients were grouped as salvage cystectomy post-trimodality therapy, primary cystectomy or primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy. Early (≤90 days) and late (>90 days) complications were compared. Disease-specific survival and overall survival were calculated using a Cox regression model, and adjusted survival curves were generated. RESULTS: The median followup from the time of cystectomy was 65.5 months. There was no difference in intraoperative and early complications between the groups. The detection of late complications was higher in salvage cystectomy post-trimodality therapy compared to primary cystectomy and primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy (p=0.03). In multivariable Cox regression analysis, salvage cystectomy post-trimodality therapy was associated with a higher incidence of any late (HR 2.3, p=0.02) and major late complications (HR 2.1, p <0.05). There was no difference in disease-specific survival (p=0.8) or overall survival (p=0.9) between the groups. CONCLUSIONS: Salvage cystectomy post-trimodality therapy for intravesical recurrence post-trimodality therapy has an intraoperative and early complication rate comparable to primary cystectomy and primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy. Salvage cystectomy post-trimodality therapy is associated with a higher risk of overall and major late complications than primary cystectomy. The disease-specific survival and overall survival of patients who require salvage cystectomy post-trimodality therapy are comparable to both groups.

To stage or not to stage: determining the true clinical significance of the biopsy tract through perinephric fat in assessing renal cell carcinoma.

AIMS: Perinephric fat invasion (PFI) is a key component of renal cell carcinoma (RCC) staging, but there are limited data pertaining to biopsy tract seeding (BTS) resulting in perirenal tissue involvement [BTS with perinephric fat invasion (BTS-P)].The aim is to correlate clinical outcomes with pathologic stage to determine whether the presence of BTS-P should be considered a criterion to stage RCC as part of the pT3a category in the absence of any other upstaging variables. MATERIALS AND RESULTS: We identified 304 renal biopsies from patients with subsequent nephrectomies for RCC; 33 of the tumours contained PFI. Each case was reviewed to determine the presence of BTS-P and other forms of invasion [e.g. non-BTS-P PFI, sinus fat invasion (SFI), and/or renal vein invasion (RVI)], and these findings were compared with survival outcomes. Ten (30%) of 33 tumours with PFI showed BTS-P as the only finding, and were otherwise pT1 tumours; six (60%) patients were alive without disease (AWOD) (mean, 77.5 months), three were lost to follow-up (LTF), and one died of other disease (DOOD). Two patients showed true PFI plus BTS-P; one was LTF and one is AWOD at 107 months. Ten (43%) of 23 patients with tumours with true invasion (PFI ± SFI and/or RVI) are AWOD (mean, 97.7 months), eight (35%) died of disease (DOD), four were LTF, and one DOOD. Kaplan-Meier survival curves showed that the cancer-specific survival was significantly worse in patients with true invasion (P = 0.044) than in those with BTS-P as the sole finding. CONCLUSION: Patients with tumours showing BTS-P only appear to have better outcomes than those with other non-PFI invasion, suggesting that this finding should not be upstaged to pT3a. Additional studies are needed to corroborate the significance of our observations.

Multiparametric Magnetic Resonance Imaging-Ultrasound Fusion Biopsy Improves but Does Not Replace Standard Template Biopsy for the Detection of Prostate Cancer.

PURPOSE: There exists a growing debate as to whether multiparametric magnetic resonance imaging with fusion transrectal ultrasound guided prostate biopsy alone without a standard template biopsy is sufficient to evaluate patients with suspected prostate cancer. Our objective was to describe our experience with fusion targeted prostate biopsy and assess whether it could obviate the need for concomitant standard 12-core template prostate biopsy. MATERIALS AND METHODS: We retrospectively reviewed our prospectively collected database of patients who underwent fusion transrectal ultrasound guided prostate biopsy. All images and lesions were graded according to the Prostate Imaging Reporting and Data System, version 2. All patients underwent targeted biopsy followed by standard 12-core double sextant biopsy within the same session. Clinically significant prostate cancer was defined as Grade Group 2 or greater prostate cancer. RESULTS: A total of 506 patients were included in analysis. Indications were elevated prostate specific antigen with a previous negative prostate biopsy in 46% of cases, prostate cancer on active surveillance in 35%, elevated prostate specific antigen without a prior prostate biopsy in 15% and an isolated abnormal digital rectal examination in 3%. For standard vs fusion prostate biopsy the overall cancer detection rate was 57.7% vs 54.0% (p=0.12) and the clinically significant prostate cancer detection rate was 24.7% vs 30.8% (p=0.001). Of the 185 patients diagnosed with clinically significant prostate cancer 29 (16%) would have been missed if only targeted fusion prostate biopsy had been performed. CONCLUSIONS: Fusion targeted prostate biopsy is associated with a higher detection rate of clinically significant prostate cancer compared to standard double sextant biopsy. However, standard double sextant biopsy should still be performed as part of the routine fusion targeted prostate biopsy procedure to avoid missing a significant proportion of clinically significant prostate cancer.

Active Surveillance of Prostate Cancer is a Viable Option for Men Younger than 60 Years.

PURPOSE: At most centers strict age criteria are lacking for eligibility for active surveillance of prostate cancer. Younger men are often counseled to undergo definitive treatment despite limited data on the outcomes of active surveillance in younger men. We compared clinical characteristics and outcomes in men who enrolled in active surveillance at age less than 60 vs 60 years old or older. MATERIALS AND METHODS: We retrospectively reviewed the records of 2 institutional cohorts of a total of 2,084 men in whom prostate cancer was managed by active surveillance between 1995 and 2016. We compared outcomes in men who began active surveillance at age 60 vs 60 years or older using the Kaplan-Meier method and Cox proportional hazards regression. RESULTS: We identified 417 and 1,667 men who began active surveillance at younger than 60 and 60 years old or older, respectively, who met study inclusion criteria. At a median followup of 6.2 years we found no significant difference between men younger than 60 and 60 years old or older in the 5-year rates of biopsy progression-free survival (83% vs 83%), treatment-free survival (74% vs 71%), metastasis-free survival (99.7% vs 99.0%) or prostate cancer specific survival (100% vs 99.7%). Of the younger men 131 (31%) ultimately underwent treatment, including for pathological progression in 67% and prostate specific antigen progression in 18%. On multivariate analysis significant predictors of biopsy progression and progression to treatment among younger men were 20% or greater involvement of any core on diagnostic biopsy (HR 2.21, p = 0.003) and prostate specific antigen density 0.15 ng/ml/ml or greater (HR 1.93, p = 0.01). CONCLUSIONS: Active surveillance is a viable option in select men younger than 60 years with low volume, low risk prostate cancer. However, patients must be surveyed closely and understand the significant likelihood of ultimately requiring treatment.

Global and Regional Respiratory Mechanics During Robotic-Assisted Laparoscopic Surgery: A Randomized Study.

BACKGROUND: Pneumoperitoneum and nonphysiological positioning required for robotic surgery increase cardiopulmonary risk because of the use of larger airway pressures (Paws) to maintain tidal volume (VT). However, the quantitative partitioning of respiratory mechanics and transpulmonary pressure (PL) during robotic surgery is not well described. We tested the following hypothesis: (1) the components of driving pressure (transpulmonary and chest wall components) increase in a parallel fashion at robotic surgical stages (Trendelenburg and robot docking); and (2) deep, when compared to routine (moderate), neuromuscular blockade modifies those changes in PLs as well as in regional respiratory mechanics. METHODS: We studied 35 American Society of Anesthesiologists (ASA) I-II patients undergoing elective robotic surgery. Airway and esophageal balloon pressures and respiratory flows were measured to calculate respiratory mechanics. Regional lung aeration and ventilation was assessed with electrical impedance tomography and level of neuromuscular blockade with acceleromyography. During robotic surgical stages, 2 crossover randomized groups (conditions) of neuromuscular relaxation were studied: Moderate (1 twitch in the train-of-four stimulation) and Deep (1-2 twitches in the posttetanic count). RESULTS: Pneumoperitoneum was associated with increases in driving pressure, tidal changes in PL, and esophageal pressure (Pes). Steep Trendelenburg position during robot docking was associated with further worsening of the respiratory mechanics. The fraction of driving pressures that partitioned to the lungs decreased from baseline (63% ± 15%) to Trendelenburg position (49% ± 14%, P < .001), due to a larger increase in chest wall elastance (Ecw; 12.7 ± 7.6 cm H2O·L) than in lung elastance (EL; 4.3 ± 5.0 cm H2O·L, P < .001). Consequently, from baseline to Trendelenburg, the component of Paw affecting the chest wall increased by 6.6 ± 3.1 cm H2O, while PLs increased by only 3.4 ± 3.1 cm H2O (P < .001). PL and driving pressures were larger at surgery end than at baseline and were accompanied by dorsal aeration loss. Deep neuromuscular blockade did not change respiratory mechanics, regional aeration and ventilation, and hemodynamics. CONCLUSIONS: In robotic surgery with pneumoperitoneum, changes in ventilatory driving pressures during Trendelenburg and robot docking are distributed less to the lungs than to the chest wall as compared to routine mechanical ventilation for supine patients. This effect of robotic surgery derives from substantially larger increases in Ecw than ELs and reduces the risk of excessive PLs. Deep neuromuscular blockade does not meaningfully change global or regional lung mechanics.

Incidence, Clinicopathological Risk Factors, Management and Outcomes of Nonmuscle Invasive Recurrence after Complete Response to Trimodality Therapy for Muscle Invasive Bladder Cancer.

PURPOSE: We describe the incidence, clinicopathological risk factors, management and outcomes of recurrent nonmuscle invasive bladder cancer after a complete response to trimodality therapy of muscle invasive bladder cancer. MATERIALS AND METHODS: We retrospectively reviewed the records of 342 patients with cT2-4aN0M0 muscle invasive bladder cancer and a complete response after trimodality therapy from 1986 to 2013. Using competing risks analyses we examined the association between baseline clinicopathological variables and nonmuscle invasive bladder cancer outcomes. Kaplan-Meier and the generalized Fleming-Harrington test were used to compare disease specific and overall survival. RESULTS: At a median followup of 9 years nonmuscle invasive bladder cancer recurred in 85 patients (25%) who had had a complete response. On Kaplan-Meier analysis baseline carcinoma in situ was associated with recurrent nonmuscle invasive bladder cancer (p = 0.02). However, on multivariate analysis carcinoma in situ and other baseline clinicopathological characteristics did not predict such recurrence. Patients with recurrent nonmuscle invasive bladder cancer had worse 10-year disease specific survival than those without recurrence (72.1% vs 78.4%, p = 0.002), although overall survival was similar (p = 0.66). Of the 39 patients (46%) who received adjuvant intravesical bacillus Calmette-Guérin 29 (74%) completed induction therapy and 19 (49%) reported bacillus Calmette-Guérin toxicity. Three-year recurrence-free and progression-free survival after induction bacillus Calmette-Guérin was 59% and 63%, respectively. CONCLUSIONS: After a complete response to trimodality therapy nonmuscle invasive bladder cancer recurred in 25% of patients, developing in some of them more than a decade after trimodality therapy. No baseline clinicopathological characteristics were associated with such recurrence after a complete response. Patients with nonmuscle invasive bladder cancer recurrence had worse disease specific survival than those without such recurrence but similar overall survival. Adjuvant intravesical bacillus Calmette-Guérin had a reasonable toxicity profile and efficacy in this population. Properly selected patients with recurrent nonmuscle invasive bladder cancer after a complete response may avoid immediate salvage cystectomy.

NCCN Guidelines Insights: Prostate Cancer Early Detection, Version 2.2016.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Prostate Cancer Early Detection provide recommendations for prostate cancer screening in healthy men who have elected to participate in an early detection program. The NCCN Guidelines focus on minimizing unnecessary procedures and limiting the detection of indolent disease. These NCCN Guidelines Insights summarize the NCCN Prostate Cancer Early Detection Panel's most significant discussions for the 2016 guideline update, which included issues surrounding screening in high-risk populations (ie, African Americans, BRCA1/2 mutation carriers), approaches to refine patient selection for initial and repeat biopsies, and approaches to improve biopsy specificity.

Patterns of Recurrence in Upper Tract Transitional Cell Carcinoma: Imaging Surveillance.

OBJECTIVE: The objective of our study was to evaluate recurrence patterns of upper tract transitional cell carcinomas (UT-TCCs) after radical nephroureterectomy (RNU). MATERIALS AND METHODS: Sixty-eight patients (mean age, 78 years; 34 men and 34 women) with UT-TCC after having undergone RNU from 2001 to 2008 were included in this study. Radiologic examinations and clinical notes were reviewed to record tumor location, tumor morphology, histologic T stages and grades, lymphovascular invasion (LVI) status, and surgical procedures. Five-year imaging and clinical follow-up (2001-2013) findings were noted at 3, 6, 12, 18, 24, 36, 48, 60, and more than 60 months after RNU for recurrence pattern and tumor-free survival. Kaplan-Meier survival curves and Cox regression models were used to assess tumor-free survival and to perform a multivariate analysis. RESULTS: Forty-one postoperative recurrences were noted in 20 patients. The mean time to relapse was 16 months, and time to relapse ranged from 1 to 66 months. Tumor site (multifocal lesions involving both renal collecting system and ureter), tumor morphology (mass), T stage (muscle invasion [T2-T4]), histologic grade (grade 3), and the presence of LVI were identified as risk factors for postoperative recurrence in UT-TCC. T stage was the only independent risk factor. CONCLUSION: Urinary tract, lymph node, liver, bone, and lung recurrences were common in patients with UT-TCC and were detected most frequently at 3-24 months. Tumor site, tumor morphology, T stage, grade, and LVI status were associated with recurrence after RNU. T stage was the only independent predictor of tumor-free survival. Close surveillance for extra-urinary tract recurrences in high-risk groups and a shorter-interval follow-up of the urinary tract in low-risk patients with adjuvant chemotherapy are recommended. Identifying recurrence patterns in UT-TCC can aid in planning an effective tailored imaging surveillance strategy.

NCCN Clinical Practice Guidelines Prostate Cancer Early Detection, Version 2.2015.

Prostate cancer represents a spectrum of disease that ranges from nonaggressive, slow-growing disease that may not require treatment to aggressive, fast-growing disease that does. The NCCN Guidelines for Prostate Cancer Early Detection provide a set of sequential recommendations detailing a screening and evaluation strategy for maximizing the detection of prostate cancer that is potentially curable and that, if left undetected, represents a risk to the patient. The guidelines were developed for healthy men who have elected to participate in the early detection of prostate cancer, and they focus on minimizing unnecessary procedures and limiting the detection of indolent disease.

Prostate cancer early detection, version 1.2014. Featured updates to the NCCN Guidelines.

The NCCN Guidelines for Prostate Cancer Early Detection provide recommendations for men choosing to participate in an early detection program for prostate cancer. These NCCN Guidelines Insights highlight notable recent updates. Overall, the 2014 update represents a more streamlined and concise set of recommendations. The panel stratified the age ranges at which initiating testing for prostate cancer should be considered. Indications for biopsy include both a cutpoint and the use of multiple risk variables in combination. In addition to other biomarkers of specificity, the Prostate Health Index has been included to aid biopsy decisions in certain men, given recent FDA approvals.
