Testis cancer is a disease that directly affects a man's sense of masculinity and involves treatments compromising sexual function. The aim of this study was to investigate the prevalence of sexual dysfunction and the influence of chronic pain on sexuality in long-term testis cancer survivors. Thus, we examined 539 patients after they had one testis removed because of a testicular germ cell tumor. Having completed oncologic therapy, all patients received a detailed questionnaire asking about the occurrence and clinical presentation of testis pain before and after orchiectomy. In addition, items from the abridged International Index of Erectile Function and Brief Sexual Function Inventory were used to gain precise information on individual sexual function. Overall, 34.5% of our testicular cancer survivors complained of reduced sexual desire, and sexual activity was reduced in 41.6%. Erectile dysfunction was present in up to 31.5% of patients. In 24.4%, the ability to maintain an erection during intercourse was impaired. Ejaculatory disorders (premature, delayed, retrograde, or anejaculation) occurred in 84.9% of our testis cancer survivors. A total of 32.4% of our participants experienced a reduced intensity of orgasm, and 95.4% experienced reduced overall sexual satisfaction. There was a significant correlation between the occurrence of chronic pain symptoms and the relative frequency and intensity of erectile dysfunction, inability to maintain an erection, ejaculation disorders, and reduced intensity of orgasm. In conclusion, chronic pain has a negative impact on sexuality in testis cancer survivors.
Testicular intraepithelial neoplasia (TIN) of the testis is the noninvasive precursor of testicular germ cell tumours (GCT) and can be detected by a single random biopsy in 5% of patients with GCT in the contralateral testes. Although it is generally presumed that TIN is dispersed throughout the testis, we realize in about 60% of TIN bearing tissue close to testis tumours that its distribution is not homogenously diffuse, but may be focal. Thus we tested whether we can improve diagnostic safety in detecting TIN by increasing the number of biopsies. We could finally evaluate 295 men with proven testicular tumours. Three biopsies of contralateral testes were taken (each 5 mm length) from one surgical incision site and fixed in Bouin's solution or glutaraldehyde. TIN cells were histologically identified by their typical morphological characteristics and additionally by placental alkaline phophatase (PlAP) immunohistochemistry. Patients revealed testicular tumour without contralateral TIN in 271 cases and with contralateral TIN in 24 cases (8.1%). In 6 of these 24 men with contralateral TIN the cells could be detected in only one (n=5) or two (n=1) of the three specimen investigated. That means in these six patients TIN could have been missed if only one single random biopsy was taken. By increasing the number of biopsies (=increasing the number of investigated seminiferous tubules) the detection rate of contralateral TIN may be increased up to 8.1%. Thus we recommend multiple testicular biopsies to increase the diagnostic safety in detection of TIN. Biopsies may be taken from one randomly chosen surgical incision site.
The aim of the study was to investigate prospectively the prevalence of testosterone deficiency (TD) in patients with testicular germ-cell cancer (TGCC) using longitudinal data. A total of 376 TGCC patients were evaluated for serum testosterone levels before, during and after the following therapies: cisplatin-based polychemotherapy, carboplatin monotherapy, radiotherapy or surgery only. Complete serial hormone analyses were performed on 160 patients (age: 33.8±9.1years, mean±SD). All patients received treatment according to the guidelines of the 'German Testicular Cancer Study Group' and the 'European Germ Cell Cancer Consensus Group' or within studies performed by the 'European Organisation for Research and Treatment of Cancer' and the 'Deutsche Krebsgesellschaft'. Main outcome measurements were sexual hormone profiles over time. Statistical analysis of 1831 testosterone serum levels over time revealed a persistent TD in 23.9% of seminoma and 26.2% of non-seminoma patients. TD was associated with subnormal residual testicular volumes (<12mL). In conclusion, TD rates are high in testis cancer patients. This is present at primary diagnosis and most likely related to testicular dysgenesis or atrophy. Our longitudinal evaluation indicates that treatment modalities have minor influence and effect on the persistently high rates of TD in TGCC patients.
Chronic phantom pain has been found in up to 78% of limb amputees and is a major complication of limb amputation. Less is known about phantom phenomena after the amputation of other, i.e. visceral, parts of the body. In a retrospective design, we identified 539 patients in whom one testis was removed between 1995 and 2005. The operative technique was a unilateral standard radical inguinal orchiectomy. The underlying pathology in all cases was a testicular germ cell tumour. All patients received a detailed questionnaire asking about the occurrence of phantom testis pain (pain felt in the removed testis), phantom testis sensations (non-painful sensations as if the removed testis was still intact) and hallucinations (illusionary perceptions on the removed testis). Furthermore, we asked about the occurrence and clinical presentation of pain before and after surgery and about pre-operative testicular pain. Out of 238 respondents, 125 patients (53%) reported any kind of phantom experience. The prevalence of phantom testis pain was 25% (60/238), non-painful phantom sensations 16% (37/238) and male gonad hallucinations 12% (28/238). Patients with phantom symptoms reported pre-operative pain in the removed testis more often than patients without phantom symptoms. This study presents first data on the clinical characteristics and possible mechanisms of the phantom testis syndrome after surgical removal of one testis.
This study endorses the notion of a clinical benefit of the sequential use of sorafenib and sunitinib and supports observations from previous studies. In terms of the optimal succession of the two TKIs, the study does not allow a definite answer.
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.
