ABSTRACT

PURPOSE: The purpose of this study was to assess the predictors of metastasis-free survival (MFS) and of the volume of the local recurrence in patients with rising prostate-specific antigen (PSA) serum level after radiotherapy for prostate cancer and referred for prostate magnetic resonance imaging (MRI) and biopsy in view of salvage treatment. MATERIALS AND METHODS: A total of 132 consecutive men (median age, 70 years; IQR, 66-77 years) with rising PSA after prostate radiotherapy who underwent prostate MRI and biopsy in view of salvage treatment between January 2010 and July 2017 were retrospectively evaluated at a single center. MFS predictors were assessed with Cox models. Predictors of the volume of the local recurrence (number of invaded prostate sectors at biopsy) were assessed using Poisson regression among variables available at PSA relapse. RESULTS: At multivariate analysis, an initial Gleason score≥8 (OR=7 [95% confidence interval (CI): 1.2-40]; P=0.03), a recent radiotherapy (OR=17 [95% CI: 3.9-72]; P<0.0001), the use of androgen deprivation therapy at PSA relapse (OR=12.5 [95% CI: 2.8-57]; P=0.001) and the number of invaded prostate sectors (OR=1.5 [95% CI: 1.1-2]; P=0.007) and maximum cancer core length (OR=0.7 [95%CI: 0.6-0.9]; P=0.002) at biopsy performed at PSA relapse were significant MFS predictors. The PSA level at relapse was significant independent predictor of the volume of local recurrence only when used as a continuous variable (P=0.0002) but not when dichotomized using the nadir+2 threshold (P=0.41). CONCLUSION: Pathological and clinical factors can help predict MFS in patients with rising PSA after prostate radiotherapy and candidates to salvage treatment. The PSA level at relapse has strong influence on the local recurrence volume when used as a continuous variable.

ABSTRACT

OBJECTIVE: To analyse the functional and oncologic outcomes at one year of focal therapy with HIFU compared with total prostatectomy in patients with localised prostate cancer (PCa). PATIENTS AND METHODS: Retrospective and monocentric study from 2008 to 2014 comparing 2 cohorts of patients with localised PCa (T1/T2 clinical stage, Gleason score≤3+4=7 and PSA<15ng/mL), one treated by focal therapy (HIFU-F group), one by robot-assisted total prostatectomy (RATP group). Primary outcome was a trifecta defined as: absence of urinary incontinence, erectile function with sexual relations without treatment, negative PSA with negative surgical margins (RATP group) or negative biopsy cores (HIFU-F group). RESULTS: The 53 patients included in the "HIFU-F" group and the 66 patients in the "RATP" group were similar in terms of preoperative PSA, D'Amico risk group, erectile function but were different in terms of age, prostatic volume, length of cancer, Gleason score. Complication rate was not different. In multivariate analyse with propensity score, "HIFU-F" group achieved a better trifecta score than "RATP" group (OR=8,3, p=0,005). CONCLUSION: In case of low or intermediate risk localised PCa, "HIFU-F" group had better functional outcomes than initial learning curse "RATP" group, at one year. A long-term evaluation by a common endpoint is necessary to judge the oncological equivalence of both techniques. LEVEL OF EVIDENCE: 3.

ABSTRACT

OBJECTIVE: To estimate the feasibility and the impact of an ERAS program after radical cystectomy for bladder cancer. MATERIALS AND METHODS: This was a retrospective study comparing a historical pre ERAS group, including all the patients undergoing cystectomy for bladder cancer from January 2013 to December 2015 with a classic procedure, and an interventional ERAS group after introducing an enhanced recovery protocol before, during and after surgery, from February 2016. The principal outcome was the postoperative length of stay. Secondary outcomes mesures were impact on perioperative complication rate (Clavien classification≥3B), readmission rate, reanimation length of stay, ileus rate and adherence to the ERAS protocol. RESULTS: There were no differences between the 2 groups as far as demographics characteristics are concerned. In total, 97 patients were included, 56 in the control group, and 41 in the ERAS group. The adherence to the protocol was about 65.8%. The ERAS group had statistically significantly shorter median length of stay (D19 versus D14; P: 0.021). The major complications rate (Clavien≥3B) were about 23.2% for the control group and 12.1% for the ERAS group (P: NS). The reinsertion of nasogastric tube were higher in the control group (39.3% vs 21.9%; P: NS) and the readmission rate was about 7.1% in the control group versus 14.6% in the ERAS group (P: NS). CONCLUSION: In conclusion, introduction and application of an enhanced recovery protocol (ERAS) after cystectomy for bladder cancer allowed for better management of postoperative outcomes. It is clearly feasible in cystectomy, and improve significantly the median postoperative length of stay. Moreover, it may be effective in terms of faster return of bowel function and reduction of majors complications. LEVEL OF EVIDENCE: 4.

ABSTRACT

PURPOSE: To evaluate the variability induced by the imager in discriminating high-grade (Gleason≥7) prostate cancers (HGC) using dynamic contrast-enhanced MRI. MATERIAL AND METHODS: We retrospectively selected 3T MRIs with temporal resolution<10 seconds and comprising T1 mapping from a prospective radiologic-pathologic database of patients treated by prostatectomy. Ktrans, Kep, Ve and Vp were calculated for each lesion seen on MRI using the Weinmann arterial input function (AIF) and three patient-specific AIFs measured in the right and left iliac arteries in pixels in the center of the lumen (psAIF-ST) or manually selected by two independent readers (psAIF-R1 and psAIF-R2). RESULTS: A total of 43 patients (mean age, 63.6±4.9 [SD]; range: 48-72 years) with 100 lesions on MRI (55 HGC) were selected. MRIs were performed on imager A (22 patients, 49 lesions) or B (21 patients, 51 lesions) from two different manufacturers. Using the Weinmann AIF, Kep (P=0.005), Ve (P=0.04) and Vp (P=0.01) significantly discriminated HCG. After adjusting on tissue classes, the imager significantly influenced the values of Kep (P=0.049) and Ve (P=0.007). Using patient-specific AIFs, Vp with psAIF-ST (P=0.008) and psAIF-R2 (P=0.04), and Kep with psAIF-R1 (P=0.03) significantly discriminated HGC. After adjusting on tissue classes, types of patient-specific AIF and side of measurement, the imager significantly influenced the values of Ktrans (P=0.0002), Ve (P=0.0072) and Vp (P=0.0003). For all AIFs, the diagnostic value of pharmacokinetic parameters remained unchanged after adjustment on the imager, with stable odds ratios. CONCLUSION: The imager induced variability in the absolute values of pharmacokinetic parameters but did not change their diagnostic performance.

ABSTRACT

PURPOSE: To evaluate functional outcomes and patients' health-related quality of life over ten years after a W-shaped ileal neobladder urinary diversion. PATIENTS AND METHODS: From 1994 to 2004, 87 patients with bladder cancer underwent a cystoprostatectomy with a W-shaped ileal neobladder. Among them, 31 patients (35.6%) were evaluated. The average follow-up was 158months, average age was 72years. We assessed functional outcomes (use of protections, USP score, uroflowmetry, postvoid residual volume), overall health-related quality of life (SF-36 score), and specific urinary-related quality of life (Ditrovie scale). RESULTS: Daytime continence was satisfactory in 29 patients (96.8%). Night-time continence was satisfactory in 27 patients (87.1%). Mean daytime continence, hyperactivity and dysuria scores of the USP were respectively 1.5/9, 3.2/21 and 2/9. Mean value of the maximum flow rate was 18mL/s for an average voiding volume of 324mL and an average postvoid residual volume of 70mL. The 8 dimensions of the SF-36 were all comparable with the French population's values. According to the Ditrovie scale whose average value was 1.83, the health-related quality of life was unchanged or little changed by urinary disorders in 28 patients (90.3%). CONCLUSIONS: Our results suggest that voiding status and health-related quality of life remain satisfactory over ten years after an orthotopic ileal neobladder derivation. LEVEL OF EVIDENCE: 5.

ABSTRACT

INTRODUCTION: Puerperal psychosis (PP) is a psychiatric disorder that occurs in 1 out of 1000 pregnancies. Well known since antiquity, its symptoms have often been described in mothers, but few studies have successfully investigated a related disorder in fathers. The characteristic of this pathology is more related to its appearance than to its semiological description which is why its nosographic place is always discussed. The objective here is to focus on the definition of PP and to suggest an entity for both genders. CASE REPORT: Our case report focused on the clinical description of an eighteen-year-old man suffering from an acute psychosis episode that occurred around the birth of his first child. Delusion followed a sudden decline in mood that lasted for a short period of time during the course of the third trimester of his wife's pregnancy. The delirium was rich with auditory and cenesthesic hallucinations, pregnancy and birth denial, feeling movements and hearing voices in his stomach. The symptoms disappeared after one month of treatment via an antipsychotic drug, risperidone. CONCLUSION: We can confirm that the symptomatic description of the disorder in this patient fits the classical descriptions of PP. Two elements make the PP different from other acute psychoses: the context of pregnancy and delirium focused on the child which can lead to a child murder. The absence of a framework precisely defining the PP does not improve its prevention and can lead to legal attitudes rather than medical care. Men suffering from acute psychosis in a context of pregnancy are submitted to the same risks as women. It is necessary to emphasize descriptions of PP in men to redefine the disease and consider that this entity involves both men and women.

ABSTRACT

RATIONALE AND OBJECTIVES: To assess the prostate T2 value as a predictor of malignancy on two different 3T scanners. PATIENTS AND METHODS: Eighty-three pre-prostatectomy multiparametric MRIs were retrospectively evaluated [67 obtained on a General Electric MRI (scanner 1) and 16 on a Philips MRI (scanner 2)]. After correlation with prostatectomy specimens, readers measured the T2 value of regions-of-interest categorized as "cancers", "false positive lesions", or "normal tissue". RESULTS: On scanner 1, in PZ, cancers had significantly lower T2 values than false positive lesions (P=0.02) and normal tissue (P=2×10(-9)). Gleason≥6 cancers had similar T2 values than false positive lesions and significantly higher T2 values than Gleason≥7 cancers (P=0.009). T2 values corresponding to a 25% and 75% risk of Gleason≥7 malignancy were respectively 132 ms (95% CI: 129-135 ms) and 77 ms (95% CI: 74-81 ms). In TZ, cancers had significantly lower T2 values than normal tissue (P=0.008), but not than false positive findings. Mean T2 values measured on scanner 2 were not significantly different than those measured on scanner 1 for all tissue classes. CONCLUSION: All tested tissue classes had similar mean T2 values on both scanners. In PZ, the T2 value was a significant predictor of Gleason≥7 cancers.

ABSTRACT

OBJECTIVE: Assess the toxicity of neoadjuvant chemotherapy (NAC), its impact on surgical schedule and postoperative morbidity of cystectomy for muscle-invasive bladder cancer (MIBC). PATIENTS AND METHODS: Retrospective multicentric study of 78 patients who underwent a cystectomy from January 2009 to March 2012 for MIBC. The following criteria have been studied: toxicity of NC (WHO classification), precystectomy interval, postoperative morbidity (Clavien), duration of stay, downsizing on CT-scan before cystectomy, and free of cancer pathology (pT0). RESULTS: Seventy-eight patients had been included, thirty-nine had a NAC. Thirty-three percent had a incomplete chemotherapy because of toxicity. Forty-eight percent had a significant toxicity and grade ≥ 3 toxicity was 33%. Median time between diagnosis and cystectomy was 12.6 weeks (0.7-38), 18 weeks with NAC (group 1) versus eight weeks without NAC (group 2) (P=0.01). In case of toxicity, the delay was 3.5 weeks longer (P=0.12). After cystectomy, 60% of patients had at least one postoperative complication; including 23% had major morbidity. NAC did not increase neither postoperative morbidity (P=0.15) nor duration of stay (18 vs 20 days; P=0.2). Radiological response rate to NC was 38%. pT0 rate was 79 vs 7.7%. The increase of precystectomy interval after NC did not worsen the pathological stage (P=0.5). CONCLUSION: NC had a high toxicity, but without impact on postoperative morbidity, and precystectomy interval did not have any impact on the prognosis. LEVEL OF EVIDENCE: 5.

ABSTRACT

OBJECTIVE: To report our experience for the management of urethro-rectal fistula by the York Mason technique. PATIENTS AND METHODS: We retrospectively analyzed the data of patients treated surgically for FUR by the technique of York Mason, between 2000 and 2012. RESULTS: Seventeen patients were included in the study. All patients had a bowel diversion before surgery. We observed four recurrences of FUR (23.5%). Recurrences occurred in a radiation field for two patients and in a oncologic recurrence for 1 patient. The fourth recurrence was treated by a second procedure of York Mason successfully. CONCLUSION: In our study, the York Mason technique was safe and reproducible for the treatment of FUR. The main factor of failure was a history of pelvic radiotherapy.

ABSTRACT

AIM: To assess multiparametric magnetic resonance imaging (mp-MRI) in predicting prostate biopsy results. MATERIALS AND METHODS: Patients who underwent mp-MRI prior to prostate biopsy were prospectively included. The prostate was subdivided into 14 sectors and mp-MRI findings assessed using a five-level subjective suspicion score (SSS). Biopsy included targeted samples of abnormal sectors and systematic samples of normal peripheral zone sectors. RESULTS: Two hundred and eighty-eight patients were included [153 biopsy naïve, 135 with negative (n = 51) or positive (n = 84) prior biopsy]. Biopsy was positive in 168 patients. mp-MRI area under the receiver operating characteristic (ROC) curve (AUC) was 69.1% (95% CI: 67.1-70.9%), 72.5% (95% CI: 69.5-76%), and 73.8% (95% CI: 68.3-79.3%) at per sector, per lobe, and per patient analysis, respectively. At the per sector level, the AUC was significantly larger if detection was limited to cancers with a Gleason score of ≥7 (72.6%; 95% CI: 69.8-75.8%; p < 0.01) or ≥8 (87.1%; 95% CI: 78.3-95.7%; p < 0.01). mp-MRI performance was significantly influenced by prostate volume (p = 0.02), the presence of a concordant hypoechoic area (p < 0.001), but not by prostate-specific antigen (PSA) value, status of prior biopsy, or radiologists' experience. SSS was significantly associated with the Gleason score in true-positive lobes and patients (p < 0.0001). Using a SSS threshold of ≥3, cancer was missed in 13/102 lobes and 4/72 patients with cancers of Gleason score ≥7. CONCLUSION: mp-MRI provides a good detection of cancers with a Gleason score of ≥7 in candidates suitable for prostate biopsy.

ABSTRACT

PURPOSE: Gold markers are frequently used for a better daily repositioning of the prostate before irradiation. The purpose of this work was to analyze if the combination of an androgen deprivation with the external irradiation could modify the position of the gold markers in the prostate. PATIENTS AND METHODS: Ten patients have been treated for a prostate cancer, using three implanted gold markers. The variations of the intermarker distances in the prostate were measured and collected on daily OBI(®) kilovoltage images acquired at 0° and 90°. Five patients had a 6-month androgen deprivation started before the external irradiation (H group) and five did not (NH group). RESULTS: A total number of 1062 distances were calculated. No distance variation greater than 3.7mm was seen between two markers, in any of the two groups. The median standard deviations of the daily intermarker distance differences were 0.7mm (range 0.3-1.2mm) for the H group and 0.6mm (range 0.2-1.2mm) for the NH group. The intermarker distances variations were noted as greater than -2mm, between -2mm and 2mm and greater than 2mm in 16.4, 83.4 and 0.2% for the H group and 1.3, 98.5 and 0.2% for the NH group, respectively. CONCLUSION: The distance variations remained less than 4mm in both groups and for all the measurements. In the NH group, the variation of the distance between two markers remained below 2mm in 98.5%. In the H group, the presence of a reduction of distance above 2mm in 16.4% of measurements could indicate the shrinkage of the prostate volume.
