Patients with risk factors (cSCC with a tumour thickness > 4 mm or recurrent disease) may develop metastases within the first 2 years despite a negative SLNB. Therefore these patients should be closely monitored during the follow-up. Based on our data SLNB does not provide diagnostic value for patients with cSCC.
Paediatric oncological therapy seems to have led to fertility impairment in about 1/3 of the participants. Considering this serious impairment, patients and their families should be given comprehensive counselling ahead of therapy to enable fertility-preserving measures. For persons who wish to have children after undergoing therapy we recommend a hormone and sperm analysis. An early analysis may enable a more successful family planning.
Hormone and semen analyses were carried out to examine the diagnostic value of hormones and hormone combinations as markers of spermatogenesis in male patients who had received oncological treatment in childhood. Hormone analyses from 73 participants and spermiograms from 42 participants were evaluated. Spearman's correlation coefficients and measures of diagnostic accuracy were calculated for the hormone and semen analysis values. Inhibin B levels of <80 ml/ml, follicle-stimulating hormone (FSH) levels of >10 IU l(-1) and a combination of the two parameters showed positive predictive values for azoospermia of 0.423, 0.6154 and 0.6667 respectively. While 32% of the 73 participants showed a combination of abnormal inhibin B and FSH values, which strongly indicates impaired spermatogenesis, 31% of the 42 spermiogram results revealed azoospermia. The hormone and semen analyses showed that approximately one-third of the participants had fertility impairment. Inhibin B alone thus does not reflect spermatogenesis as well as inhibin B in combination with FSH in patients who have undergone cancer treatment in childhood. Both parameters should therefore be evaluated in paediatric cancer follow-up programmes to allow better identification of treatment regimens that cause persistent azoospermia in male childhood cancer survivors.
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.
