Few patients with advanced GCT need complex vascular, skeletal or intestinal surgery in an interdisciplinary setting with good functional and oncological outcome. Due to the complexity, treatment should be performed at specialized centres.
Definition of chronic male genital tract inflammation and its impact on male infertility is still a matter of debate. In particular, DNA integrity has been reported to be disturbed in subfertile men. Thus, the aim of this study was to investigate an association of DNA integrity to altered standard semen parameters as well as inflammatory parameters such as peroxidase-positive cells, macrophages and seminal interleukin-6 concentration. Macrophages were detected by CD18/HLA-Dr staining, and DNA integrity was analysed by acridine orange staining using flow cytometry. Interleukin-6 was detected by ELISA. Normal DNA integrity showed a significant correlation to sperm number and progressive motility. Moreover, a significant inverse correlation of DNA integrity to Interleukin-6 and macrophages could be demonstrated. Further on, seminal interleukin-6 also significantly correlated to macrophages. No association has been observed between the number of peroxidase-positive cells and normal DNA integrity. As disturbed DNA integrity has been reported to negatively influence spermatozoon-egg interaction and even fertilisation rates following ICSI, and as early miscarriages have been associated with sperm DNA damage, it should be screened very carefully for male genital tract inflammations in couples undergoing infertility treatment. Measuring Interleukin-6 seems superior to assessment of the number of leucocytes alone and additional assessment of DNA integrity into the diagnostic work-up should be considered.
Benchmark survival estimates for patients receiving perioperative chemotherapy for locally advanced penile squamous-cell carcinoma have been provided, with no substantial differences observed between neoadjuvant and adjuvant administration. This analysis may result in improved patient information, although prospective studies are warranted.
Objective
To investigate the diagnostic performance of gallium‐68 prostate‐specific membrane antigen positron emission tomography/computed tomography (68Ga‐PSMA PET/CT) in patients with recurrent prostate cancer with regard to the presence of lymph node metastases (LNM) and local recurrences after primary radiotherapy.
Patients and methods
We retrospectively reviewed 142 patients following salvage radical prostatectomy (sRP), 50 of which had a 68Ga‐PSMA PET/CT performed as a preoperative staging module. Predictive clinical parameters were analysed in a multivariate Cox regression analysis. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) and the accuracy of 68Ga‐PSMA PET/CT were analysed with regard to LNM and local recurrence.
Results
In all, 613 lymph nodes were resected in 40 patients and 23 lymph nodes had metastatic deposits in 14 patients. In all patients local recurrence could have been found with 68Ga‐PSMA PET/CT. Sensitivity, specificity, PPV and NPV and accuracy on a per lymph node basis were 34.78% (16.38–57.2%), 100% (99.38–100%), 100%, 97.52% (96.69–98.15%) and 97.55% (96.00–98.62%). For detecting local recurrence, the sensitivity and PPV were both 100% with an accuracy of 100% (92.89–100%).
Conclusion
68Ga‐PSMA PET/CT should be the standard imaging in biochemical recurrent prostate cancer. With this imaging module one detects first local recurrence and can detect locoregional and distant metastases more precisely than standard CT and bone scan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
