RESUMEN

PURPOSE: To identify predictive factors for immediate continence after radical prostatectomy. PATIENTS AND METHODS: A total of 1553 patients underwent radical prostatectomy in a single institution (670 RRP, 883 RARP), had complete perioperative data and follow-up for urinary continence and were included in this prospective analysis. Immediate continence was defined as no pad usage after catheter removal. Evaluated parameters included age, body mass index, ECOG performance status, erectile function, prostate volume, PSA, Gleason score, tumor stage and D'Amico risk groups, as well as surgical approach (RRP, RARP), surgeon volume, nerve-sparing, lymphadenectomy, blood transfusions and duration of catheterization. RESULTS: A total of 240 men (15.5 %) did not require any pads 1 day or later after removal of the transurethral catheter. Correlation of parameters with immediate continence revealed significance for age (p < 0.001), ECOG-score (p = 0.025), erectile function (p = 0.001), nerve-sparing (p = 0.022), Gleason score (p = 0.002) and surgeon volume (p ≤ 0.022). Multivariate analyses identified IIEF-score >21 (p = 0.031), ECOG (p < 0.05), bilateral nerve-sparing (p = 0.049), Gleason score <3 + 4 (p ≤ 0.028), less blood transfusion (p ≤ 0.044) and surgeon volume (p ≤ 0.042) as the remaining prognostic parameters for immediate continence after radical prostatectomy. The type of surgical approach (robotic vs. open radical prostatectomy) did not yield significant influence. CONCLUSION: Evaluating continence in a contemporary prospective cohort revealed 15.5 % of patients never requiring a pad postoperatively. Predictive parameters for immediate continence were erectile function, ECOG, bilateral nerve-sparing, less blood transfusion and Gleason score. Furthermore, the surgeon's experience but not his operative technique had a significant impact on immediate postoperative continence.

RESUMEN

BACKGROUND: Chemotherapy-associated ovarian damage comprises not only infertility, but also premature menopause. The latter has been reported as a consequence of alkylating chemotherapy for breast cancer or Hodgkin's lymphoma. In this study, we assessed the long-term impact of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone)-like regimens on ovarian function in patients with aggressive non-Hodgkin lymphoma (NHL). PATIENTS AND METHODS: Long-term survivors after CHOP or CHOP plus etoposide (CHOEP) treatment within the Mabthera International Trial or the NHL-B1 trial of the German NHL Study Group were requested to respond to a questionnaire and to consent to blood sampling for hormone assessment. RESULTS: A total of 46 of 81 contacted patients with a median age of 32.5 years at the time of enrolment into the aforementioned clinical trials responded to the questionnaire. The median follow-up after completion of treatment was 14 years. Last menstrual bleeding occurred significantly earlier in patients compared with the general population (47 versus 51 years, P < 0.0001). In comparison to the distribution of menopausal symptoms in the general population, the percentage of women with moderate or severe menopausal symptoms was increased. In 23 patients who agreed to participate in laboratory analyses, anti-Muller hormone as a marker of ovarian reserve was decreased when compared with correspondent age groups of the general population. CONCLUSION: Although most female patients regain fertility after CHOP-like chemotherapy, late ovarian impairment occurs frequently. Therefore, awareness of such delayed side-effects at the time of counselling is of importance.

RESUMEN

OBJECTIVES: To evaluate the Prostate Imaging Reporting and Data System (PI-RADS) proposed by the European Society of Urogenital Radiology (ESUR) for detection of prostate cancer (PCa) by multiparametric magnetic resonance imaging (mpMRI) in a consecutive cohort of patients with magnetic resonance/transrectal ultrasound (MR/TRUS) fusion-guided biopsy. METHODS: Suspicious lesions on mpMRI at 3.0 T were scored according to the PI-RADS system before MR/TRUS fusion-guided biopsy and correlated to histopathology results. Statistical correlation was obtained by a Mann-Whitney U test. Receiver operating characteristics (ROC) and optimal thresholds were calculated. RESULTS: In 64 patients, 128/445 positive biopsy cores were obtained out of 95 suspicious regions of interest (ROIs). PCa was present in 27/64 (42%) of the patients. ROC results for the aggregated PI-RADS scores exhibited higher areas under the curve compared to those of the Likert score. Sensitivity/Specificity for the following thresholds were calculated: 85 %/73 % and 67 %/92 % for PI-RADS scores of 9 and 10, respectively; 85 %/60 % and 56 %/97 % for Likert scores of 3 and 4, respectively [corrected. CONCLUSIONS: The standardised ESUR PI-RADS system is beneficial to indicate the likelihood of PCa of suspicious lesions on mpMRI. It is also valuable to identify locations to be targeted with biopsy. The aggregated PI-RADS score achieved better results compared to the single five-point Likert score. KEY POINTS: • The ESUR PI-RADS scoring system was evaluated using multiparametric 3.0-T MRI. • To investigate suspicious findings, transperineal MR/TRUS fusion-guided biopsy was used. • PI-RADS can guide biopsy locations and improve detection of clinically significant cancer. • Biopsy procedures can be optimised, reducing unnecessary negative biopsies for patients. • The PI-RADS scoring system may contribute to more effective prostate MRI.

RESUMEN

Two monoclonal antibodies (LAM-A and LAM-B) specific for laminin from normal and neoplastic parietal yolk sac (PYS) cells were produced in rats immunized with a mouse yolk sac carcinoma cell line. Both antibodies immunoprecipitated the 400,000- and 200,000-Da chains of laminin and reacted with purified PYS laminin in ELISA. LAM-A reacted with mouse and rat PYS laminin, whereas LAM-B reacted only with mouse PYS laminin. Formaldehyde- and methanol-fixed adult and fetal somatic tissues were immunohistochemically unreactive with either of the two antibodies. In acetone-fixed tissue sections, both antibodies reacted weakly with some medullary tubules of the kidney, the follicular basement membrane of the ovaries, and the seminiferous tubules. The antibodies appear to react with the polypeptide determinants residing on the terminal portion of the long arm of laminin. It is concluded that laminin derived from normal or malignant PYS cells has distinct antigenic sites that are immunochemically not apparent in most other basement membranes.
