Elevated neutrophil-to-lymphocyte ratio is independently associated with poorer chemotherapeutic response and overall survival in patients with advanced or metastatic bladder cancer. The neutrophil-to-lymphocyte ratio can be an inexpensive novel factor in prognosticating disease progression and providing better patient counseling.
ObjectiveTo determine the role of neutrophil-to-lymphocyte ratio (NLR) in prognosticating survival outcomes in patients with advanced/metastatic urothelial bladder cancer.MethodsWe retrospectively reviewed 84 patients undergoing radical cystectomy (RC) for UCB from January 2002 to June 2012. NLR was computed (median: 5 days) prior to surgery. No patients received neoadjuvant chemotherapy. NLR was analyzed as a continuous variable and a cut-off point of 2.7 was obtained, with a statistical receiver operating characteristics of 0.74. Kaplan–Meier curves, multivariate Cox proportional hazard and logistics regression models were used to predict NLR association with survival outcomes.ResultsThe median follow-up period was 30.1 months (range: 3.2–161.7) owing to high recurrence rate and subsequent mortalities, compared to the median 64.7 months in patients alive at the end of study period. NLR ≥2.7 was associated with worse survival outcomes (5-year disease-specific survival: 22% vs 58%, p = 0.017, 95%CI: 1.193–6.009; 5-year overall survival: 23% vs 60%, p = 0.008, 95%CI: 1.322–6.147). Furthermore, on multivariate analyses, higher NLR was independently associated with higher recurrence rate (p = 0.007, HR =6.999, 95%CI: 1.712–28.606), higher T staging (p = 0.021, HR = 3.479, 95%CI: 1.212–9.990) and lymph node involvement (p = 0.009, HR = 4.534, 95%CI: 1.465–14.034).ConclusionThis study suggests that NLR can be an inexpensive novel factor for patients risk stratification pre-operatively. This improves patient counseling and identifies patients who may benefit from multimodal treatment.
Background
There have been few reports on the feasibility and safety of robotic multivisceral surgeries. The da Vinci Xi boasts significant upgrades that improve its applicability in combined resections. We report our early experience of multivisceral, multi‐quadrant resections with the Xi system.
Methods
Between May 2015 and August 2019, 13 multivisceral resections were performed. Patient demographics, procedural data, and perioperative outcomes were evaluated.
Results
The procedures were completed at a median operative time of 290 (range, 210–535) minutes. The median postoperative length of hospital stay was 3.5 (range, 2–7) days. There was one case of readmission for anastomotic leak, but no positioning injuries, external robot arm collisions or issues arising from trocar position. There were no cases of perioperative mortality.
Conclusion
Multivisceral resections can be safely accomplished using the Xi. Further studies are necessary to ascertain whether there are benefits of the robotic approach over conventional laparoscopy in these complex cases.
Objective
To evaluate the efficacy of multiparametric magnetic resonance imaging (mp-MRI) using Prostate Imaging Reporting and Data System version 2.0 (PI-RADSv2) definitions in detecting organ-confined prostate cancer.
Methods
All patients who underwent radical prostatectomy between January 1, 2014 and December 30, 2014 were identified. All underwent mp-MRI within 180 days before surgery. Those with prior pelvic irradiation or androgen deprivation therapy were excluded. Fully embedded, whole-mount histopathology was centrally reviewed and correlated with imaging for tumour location, Gleason score (GS) and stage.
Results
There were 39 patients included, of which 35 (90%) had mp-MRI done post-biopsy. A total of 93 cancer foci were identified on whole-mount pathology, of which mp-MRI detected 63 (68%). Of those detected by mp-MRI, 14 were PI-RADS 3 (
n
= 6 for GS 6,
n
= 8 for GS 7, no GS ≥ 8) and 49 were PI-RADS 4–5 (
n
= 7 for GS 6,
n
= 33 for GS 7, and
n
= 9 for GS ≥ 8). There were 30 (32%) cancer foci missed by mp-MRI (
n
= 15 for GS 6,
n
= 13 for GS 7 and
n
= 2 for GS ≥ 8). A lesion classified as PI-RADS 4–5 predicted a higher grade cancer on pathology as compared to PI-RADS 3 (for GS 7 lesions, odds ratio [OR] = 3.53, 95% CI: 0.93–13.45,
p
= 0.064). The mp-MRI size detection limit was 20 mm
2
and 100 mm
2
for 50% and 75% probability of cancer, respectively. In associating with radiological and pathologic stage, the weighted Kappa value was 0.69 (
p
< 0.0001). The sensitivity and positive predictive values for this study were 68% (95% CI: 57%–77%) and 78% (95% CI: 67%–86%), respectively.
Conclusion
In this predominantly post-biopsy cohort, mp-MRI using PI-RADSv2 reporting has a reasonably high diagnostic accuracy in detecting clinically significant prostate cancer.
