Erectile dysfunction in men treated for testicular cancer

Sexual function using the EORTC QLQ-TC26 in testicular cancer survivors: A multi-institutional, cross-sectional study

OBJECTIVE

To evaluate sexual function after treatment using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Testicular Cancer 26 (EORTC QLQ-TC26) questionnaire in Japanese testicular cancer (TC) survivors in a multi-institutional, cross-sectional study.

METHODS

This study enrolled TC survivors who visited any of eight high-volume institutions in Japan from 2018 to 2019. After obtaining informed consent, participants completed the EORTC QLQ-TC26 questionnaires. We evaluated sexual function after treatment for TC using the EORTC QLQ-TC26 and analyzed the impact of treatment on sexual function in TC survivors.

RESULTS

A total of 567 TC survivors responded to the EORTC QLQ-TC26. Median age at the time of response was 43 years (interquartile range [IQR] 35-51 years), and median follow-up period after treatment was 5.2 years (IQR 2.2-10.0 years). Sexual function, particularly ejaculatory function, was significantly lower after post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) than after Surveillance or Chemotherapy groups (p < 0.05). In the PC-RPLND group, nerve-sparing procedure preserved postoperative ejaculatory function after RPLND compared with the non-nerve-sparing and offered improved ejaculatory function with time. On multivariate analysis, RPLND was a significant predictor of post-treatment ejaculatory dysfunction, particularly without nerve-sparing (odds ratio 3.0, 95% CI 1.2-7.7, p < 0.05). In addition, TC survivors with nerve-sparing RPLND had higher sexual activity than those without.

CONCLUSION

This survey of the EORTC QLQ-TC26 showed that sexual function and activity in TC survivors after RPLND was reduced in the absence of nerve-sparing techniques.

Sexual function in male cancer survivors is not correlated to sperm quality

PURPOSE

Both infertility and erectile dysfunction (ED) are known long-term consequences of cancer treatment in young male cancer survivors. In the present study, we aimed to assess whether sperm quality and sexual function in male cancer survivors are associated.

METHODS

In this prospective study, n = 244 patients male cancer survivors who underwent sperm analysis and cryopreservation between 2008 and 2018 prior to the initiation of gonadotoxic treatment were invited. In total n = 50 had a follow-up sperm analysis and completed two questionnaires, the Aging Males' Symptom Scale (AMS) and the International Index of Erectile Function (IIEF-EF). Differences between the individual parameters were analyzed using the Wilcoxon or Mann Whitney test.

RESULTS

Azoospermia was present in n = 16/50 (32.0%) patients at time of follow-up. ED occurred in n = 9/43 (20.9%) patients and was observed more frequently in patients with oligo- or azoospermia than in those with normospermia, even though this association was not statistically significant. Sperm parameters (total sperm count, sperm concentration, progressive motility) did not differ between time of cryopreservation and time of follow-up. Mean total, somatic, psychological, and sexual AMS score was 23.6, 9.9, 6.6, and 6.8, respectively. Mean total IIEF-EF score was 27.3, indicating mainly mild ED.

CONCLUSIONS

More than one-third of cancer patients suffered from azoospermia, and ED was primarily present in this subgroup. We recommend implementing the screening of sexual dysfunction in the annual sperm testing that should be offered to all men after gonadotoxic treatment. Our study highlights the importance of counseling young cancer patients on both aspects-future infertility and sexual function-prior to treatment and at follow-up visits.

Erectile dysfunction among testicular cancer survivors: A systematic review and meta-analysis

BACKGROUND

Erectile dysfunction is one of the common complications of testicular cancer with a prevalence of 11.3%-84%. It has devastating effects on men and their partner's quality of life, sexual satisfaction, and sexual experience. The findings of the previous studies on this matter were uneven and inconsistent. Therefore, this systematic review and meta-analysis is conducted to acquire a more recent and comprehensive result.

METHODS AND MATERIALS

PubMed, Scopus, Goggle scholar, Science Direct, African Index Medicus, African Journal online, EMBASE, and Cochrane Library databases were searched. All necessary data were extracted using a standardized data extraction format. Data were analyzed using STATA 14 statistical software. A heterogeneity of studies was assessed using the I2 statistics. Publication bias was checked by using a funnel plot and Egger's regression test. A random-effects model was computed to estimate the pooled prevalence of erectile dysfunction.

RESULT

Fourteen full-text studies were included in this systematic review and meta-analysis. The pooled prevalence of erectile dysfunction among testicular cancer survivors was found to be 34.60% (95% CI: 25.89, 43.30 [I2 = 95.9% p = 0.000]). Study design subgroup analysis indicated that the pooled prevalence of erectile dysfunction was 50.02% (95% CI: 22.78, 77.28% [I2 = 96.1 p = 0.000]), and 27.36% (95% CI: 19.23, 34.48% [I2 = 91.6, P = 0.000]) in the case-control and cohort studies, respectively. Likewise, the level of erectile dysfunction was varied based on ED erectile dysfunction measuring tools and testicular cancer treatment modalities.

CONCLUSION

In this study erectile dysfunction was found to be a highly prevalent complication in testicular cancer survivors. It had also causes of heterogeneity in terms of treatment modalities, study designs, and measuring tools. Therefore prevention of this complication should be the concern of the responsible bodies.

Prevalence of erectile dysfunction in male survivors of cancer: a systematic review and meta-analysis of cross-sectional studies

Background

Prevalence of erectile dysfunction (ED) in male survivors of cancer across cancer types has not been systematically analysed.

Aim

To estimate the prevalence of ED in all types of cancer and identify characteristics associated with ED in survivors of cancer.

Design and setting

Systematic review and meta-analysis (MA) of cross-sectional studies.

Method

MEDLINE, CINAHL, PsycINFO, and EMBASE were searched, targeting reports published from inception to 1 February 2020. All retrospective or prospective studies reporting prevalence of ED in male patients with cancer and using a validated tool for detection of ED were included. A random-effects MA model was used to pool prevalence of ED as absolute estimates at three different stages, that is, ‘healthy’, ‘at diagnosis’, and ‘after treatment’. A univariate MA regression including the three-level group variable as the only independent variable was used to assess the difference in ED prevalence across the three groups. Further MAs were conducted for studies involving patients at diagnosis and after treatment, and statistical inferences were made with setting for multiple testing controlling for a false discovery rate (FDR) <0.05.

Results

In total, 1301 studies were assessed for inclusion. Of these, 141 were potentially eligible and subsequently scrutinised in full text. Finally, 43 studies were included with a total of 13 148 participants. Overall, pooled data of the included studies showed an ED prevalence of 40.72% (95% confidence interval [CI] = 31.80 to 50.29) in patients with cancer, with prevalences of 28.60% (95% CI = 12.10 to 53.83) at time of diagnosis and 42.70% (95% CI = 32.97 to 53.03) after treatment, with significant difference between these two stages and across cancer locations, controlling for an FDR <0.05.

Conclusion

Erectile dysfunction was particularly high in male survivors of cancer and was associated with cancer treatment, cancer site, and age.

Erectile dysfunction and cancer: current perspective

Erectile dysfunction (ED) is one of the major but underreported concerns in cancer patients and survivors. It can lead to depression, lack of intimacy between the couple, and impaired quality of life. The causes of erectile dysfunction are psychological distress and endocrinal dysfunction caused by cancer itself or side effect of anticancer treatment like surgery, radiotherapy, chemotherapy and hormonal therapy. The degree of ED depends on age, pre-cancer or pre-treatment potency level, comorbidities, type of cancer and its treatment. Treatment options available for ED are various pharmacotherapies, mechanical devices, penile implants, or reconstructive surgeries. A complete evaluation of sexual functioning should be done prior to starting anticancer therapy. Management should be individualized and couple counseling should be an integral part of the anticancer treatment.

Impact of cancer therapy on post-treatment ejaculation disorder and sexual life in testicular cancer survivors

OBJECTIVE

To evaluate the impact of cancer therapy on post-treatment ejaculation in patients with testicular cancer.

METHODS

A total of 74 testicular cancer survivors provided completed International Index of Erectile Function-15 questionnaires before and after treatment between 2010 and 2017. Sexual function, particularly ejaculatory function, was evaluated before and after treatment. In this study, patients who answered "1 = almost never/never" or "2 = a few times" for questionnaire number 9 (ejaculation frequency) were defined as having "ejaculation disorder."

RESULTS

Of 74 testicular cancer survivors, 50 (68%) had no ejaculation disorders before treatment. Four (44%) of nine survivors, who received chemotherapy and retroperitoneal lymph node dissection, developed ejaculation disorders after treatment. On multivariate analysis, retroperitoneal lymph node dissection was a significant predictor of post-treatment ejaculation disorder (P = 0.042). Of 60 survivors with evaluable ejaculation function after treatment, 24 (40%) did not attempt sexual intercourse, and multivariate analysis showed ejaculation disorder had a significant negative impact on having sexual intercourse (P = 0.035). Furthermore, the mean International Index of Erectile Function-15 scores in the groups with and without ejaculation disorders after treatment were 24.0 and 51.9, respectively (P < 0.001).

CONCLUSION

Ejaculation disorders occur at high rate after retroperitoneal lymph node dissection. Many testicular cancer survivors reporting no sexual intercourse have ejaculation disorders, suggesting an adverse impact on sexual life. Urologists should provide proper counselling regarding the risk of ejaculation disorder and its possible impact on sexual life.

Erectile Dysfunction in Germ Cell Tumor Survivors

Purpose

Germ cell tumors (GCTs) are the most common malignant neoplasms in adolescents and young adults, and most patients with these tumors can be completely cured. Therefore, maintaining quality of life (QOL) is important. Erectile dysfunction (ED) is one factor that reduces the QOL of GCT survivors. We aimed to clarify the relationship between ED and age, follow-up period, serum levels of hormones, and treatment methods for GCT survivors.

Materials and Methods

We evaluated ED using the Sexual Health Inventory for Men questionnaire (SHIM) and measured serum levels of hormones in survivors after GCT treatment. The relationships between the SHIM score responses and age, serum levels of hormones, follow-up period, and treatment methods were assessed using a logistic analysis.

Results

Fifty-two GCT survivors were enrolled and 46 survivors completed the SHIM. The median age, follow-up period, and SHIM score were 38 years, 35 months, and 18, respectively. Regarding the SHIM scores, 85% had scores <22 and 46% had scores <17. The percentage of SHIM scores <17 was 69% in patients with under 2 years of follow-up. It significantly improved to 33% in patients with over 2 years of follow-up. The multivariate analysis identified the follow-up period as an independent factor for SHIM scores <17. Age, serum levels of hormone, and treatment method were not significant factors for SHIM scores <17.

Conclusions

Improvement of SHIM score can be expected after GCT treatment regardless of age, serum levels of hormone, and treatment method.

Erectile dysfunction in testicular cancer survivors: a meta-analysis of case-control studies

Introduction

Testicular cancer (TC) is the most frequent cancer among men aged 14-44 years. The risk of erectile dysfunction (ED) in TC patients varied within a wide range across different studies. This study aims to estimate the risk of ED in TC patients by conducting a meta-analysis of case-control studies.

Material and methods

Relevant studies were searched using PubMed, EMBASE, Scopus, and the Cochrane Library up to June 2019. Case-control studies that reported the incidence of ED in TC patients were included.

Results

A total of 8 studies involving 2060 TC patients and 2651 healthy men were included. All the TC patients underwent unilateral orchiectomy; other treatment modalities were also conducted if necessary. ED occurred in 16.9% (348/2060) of TC patients and 9.4% (251/2651) of healthy men. Compared with healthy men, TC patients experienced a significantly increased risk of ED (OR = 2.39, 95% CI: 1.56-3.67). Substantial heterogeneity was observed. In addition, subgroup analysis revealed that the risk (OR = 3.76, 95% CI: 2.45-5.78) for ED in TC patients with follow-up < 5 years was significantly higher than that (OR = 1.61, 95% CI: 1.10-3.67) with follow-up ≥ 5 years. Heterogeneity was improved after subgroup analysis.

Conclusions

TC patients experienced an increased risk for ED compared with healthy men. The long-term risk for ED in TC patients was lower than the short-term risk.

Fertility considerations in men with testicular cancer

The modern approach to cancer management has evolved into a multidisciplinary initiative focused not only on cancer specific and overall survival, but also patient quality of life and survivorship. Future fertility is often a major concern for young patients undergoing cancer therapy. Fertility preservation has emerged as a viable but significantly underutilized option. Patients and families should be aware of the varying effects of antineoplastic therapy on their future fertility to allow for an informed decision regarding their fertility preservation options. In this review we discuss the epidemiology, pathophysiology, and management of fertility in the setting of testicular cancer diagnosis and treatment.

Long-Term Follow Up of the Erectile Function of Testicular Cancer Survivors

The diagnosis of testicular cancer (TC) can have a considerable and persistent impact on a patient's sexuality, especially given its location. The high prevalence of TC in young adults, and the good prognosis, explain the great interest in sexual dysfunction and its influence on post-treatment quality of life. The aim of this study was to evaluate the impact of the diagnosis and treatments (inguinal orchiectomy and chemotherapy) on sex life. For this purpose, we recruited 241 TC patients attending the Laboratory of Seminology-Sperm Bank "Loredana Gandini" for sperm cryopreservation (mean age 31.3 ± 6.9 years) and 223 cancer-free healthy men who were undergoing andrological screening (mean age 32.0 ± 7.7 years). The IIEF-15 questionnaire was administered at the baseline (post-orchiectomy, pre-chemotherapy-T0) and at 6 (T1), 12 (T2), 18 (T3), 24 (T4), 48 months (T5) and >5 years (T6, median 96 months) after chemotherapy to all patients, to evaluate the following domains: erectile function (EF), orgasmic function (OF), sexual desire (SD), intercourse satisfaction (IS) and overall satisfaction (OS). A subgroup of patients also underwent blood sex hormone analysis for further correlations with IIEF scores. At the baseline, 37.7% of patients had erectile dysfunction (EF score <26) and all IIEF domains except OF showed significantly lower scores than in controls (p < 0.001). Long-term follow-up revealed persistently lower scores in TC survivors than in controls for EF, SD, IS, and OS. Furthermore, most IIEF domains did not improve significantly in TC patients during the duration of the follow-up, with the exception of EF, which showed a significant improvement from T2. Finally, no significant correlation was found between hormone levels (gonadotropin and testosterone) and IIEF-15 scores. In conclusion, TC and its treatment have a significant effect on sexuality. The absence of a clear correlation with biochemical hypogonadism suggests that this may to a large extent be due to the surgical procedure itself, or to the psychological impact of a cancer diagnosis.

Physical long-term side-effects in young adult cancer survivors: germ cell tumors model

PURPOSE OF REVIEW

After the important advances in the treatment of germ cell tumors (GCTs) leading to high cure rates, physical long-term side-effects represent an important cause of death in these young adult survivors. Highlighting these physical long-term side-effects, their monitoring and their prevention modalities is necessary for a better management of these cancer survivors.

RECENT FINDINGS

Impaired fertility, increased risk of developing a second cancer, cardiac, pulmonary, renal and neural toxicity, hearing and vision impairment are the major physical side-effects in young adult cancer survivors. Long-term cardiac toxicity, next to second malignancies, represents life-threatening conditions in testicular cancer survivors. The long-term nephrotoxity in testicular GCTs survivors is most frequently associated to the treatment either in those treated with cisplatin-based chemotherapy, mainly Bleomycine, Etoposide, Cisplatin, or those receiving infradiaphragmatic radiation therapy, whereas pulmonary toxicity is mainly attributed to bleomycin related toxicities.

SUMMARY

There are no clear and comprehensive data concerning the monitoring and prevention of long-term side-effects in testicular cancer survivors. Physical activity and interventions in modifiable cardiovascular risk factors and lifestyles may reduce the incidence of long-term side-effects in these cancer survivors.

Fertility preservation of patients with testicular cancer

Background

Testicular cancer (TC) is one of the most common malignancies in young men of reproductive age. Although TC is a curable malignancy with a high survival rate, its treatment requires various cytotoxic modalities and negatively impacts spermatogenesis; therefore, the fertility preservation of patients with TC has been studied.

Methods

In order to give an overview of fertility preservation in patients with TC, the literature was reviewed. Original and review articles were identified and examined on the basis of PubMed database searches.

Results

Chemotherapy and radiotherapy damage spermatogenesis and retroperitoneal lymph node dissection negatively impacts ejaculatory function. Testicular sperm extraction facilitates successful sperm retrieval in patients with TC with postchemotherapy azoospermia. Although preserved sperm is used with a very low frequency (8%), the conception rates in those who have used sperm are not inferior.

Conclusion

The number of studies is limited, and because numerous treatment factors affect fertility, outstanding questions remain about preserving the fertility of patients with TC. Further studies are necessary in order to determine the best means of preventing and treating infertility in patients with TC.

Long-term recovery of normal sexual function in testicular cancer survivors

Testicular cancer (TC) is the most common solid cancer in men between the third and fourth decade of life. Due to successful treatment approaches, TC survivors (TCSs) have long life expectancy, but with numerous potential long-term sequelae, including sexual dysfunction. We investigated predictors of long-term normal sexual function (SF) recovery in TCSs. Sociodemographic, medical, and psychometric data were analyzed in 143 Caucasian-European TCSs, who underwent orchiectomy at a single institution. Health-significant comorbidities were scored with the Charlson Comorbidity Index (CCI). Patients completed the International Index of Erectile Function (IIEF). Statistical models tested the association between predictors (including age at surgery, body mass index, CCI, and adjuvant therapy: radiotherapy [RT], chemotherapy [CT], CT followed by retroperitoneal lymph node dissection [RPLND] and RPLND alone) and the long-term recovery of normal SF (defined as IIEF-erectile function [EF] ≥26, and sexual desire [SD], intercourse satisfaction [IS] orgasmic function [OF], and overall satisfaction [OS] domain scores in the upper tertiles). At a mean follow-up of 86 months, 35 (25.5%) TCSs had erectile dysfunction (ED), with 16 (11.2%) experiencing severe ED. Median time of EF recovery was 60, 60, and 70 months after CT, RT, and RPLND, respectively. Only adjuvant RT emerged as an independent predictor of nonrecovery of normal EF (HR: 0.55, P= 0.01). Neither adjuvant CT nor CT plus RPLND or RPLND alone significantly impaired the recovery of normal erections. Adjuvant therapy was not associated with impaired recovery of normal sexuality as a whole, considering the IIEF-SD, -OF, -IS, and OS domains.

Understanding and Managing Erectile Dysfunction in Patients Treated for Cancer

Cancer can cause sexual adverse effects by direct and indirect pathways. It can involve sexual organs, indirectly affect body image, or cause fatigue or depression with subsequent effects on libido. Erectile dysfunction (ED), the inability to obtain or maintain an erection firm enough for sexual intercourse, can also result from adverse effects of cancer treatment, such as fatigue, pain, or anxiety about therapy. In addition, depressed feelings about having cancer can affect sexuality, causing a range of signs and symptoms that can lead to ED. Chemotherapy, hormone therapy, surgery, and radiation can all cause sexual adverse effects. Additional factors that play a role include patient age and degree of ED before starting cancer treatment. In this article, we discuss how chemotherapy, hormone therapy, surgery, and radiation affect erectile function as well as possible treatment options for ED.

Update in germ cell tumours

PURPOSE OF REVIEW

The purpose of this study is to update the reader on advances in postpubertal male germ cell tumours (GCTs) over the last 18 months.

RECENT FINDINGS

Single nucleotide polymorphisms, including in four sex-determination genes, have been identified as additional genetic susceptibility loci to testicular GCT development. New insights into cisplatin resistance implicate the PDGFR-PIK3CA-AKT and RAS pathways. Circulating tumour cells and circulating microRNAs are potential new biomarkers. In clinical stage I (CS-I) GCT, two large studies have confirmed the excellent outcomes achieved with surveillance, which is now the management option of choice for CS I-A nonseminoma and all CS-I seminomas; CS I-B nonseminoma remains controversial. First-line trials of dose-dense multidrug regimens reported promising results but have not yet supplanted BEPx4. Survivorship issues, including secondary malignancies from chemotherapy, remain important in this disease and are a continuing focus of ongoing research.

SUMMARY

Important research questions remain across all aspects of GCT. The next decade is likely to produce many new and exciting discoveries that will benefit GCT patients.

Pharmacologic and surgical therapies for sexual dysfunction in male cancer survivors

The recent recognition that many men experience sexual dysfunction following their diagnosis and treatment of genitourinary cancers, has led to the development multiple varied strategies that attempt to restore or preserve that function. In this manuscript we review the understanding of why it happens, highlight novel management strategies and discuss the concept of penile rehabilitation (PR) following prostate cancer (PCa) treatment, glans preserving strategies among men diagnosed with penile cancer and address the controversial issue of testosterone therapy in men with PCa.

Sexual dysfunction and infertility as late effects of cancer treatment

Sexual dysfunction is a common consequence of cancer treatment, affecting at least half of men and women treated for pelvic malignancies and over a quarter of people with other types of cancer. Problems are usually linked to damage to nerves, blood vessels, and hormones that underlie normal sexual function. Sexual dysfunction also may be associated with depression, anxiety, relationship conflict, and loss of self-esteem. Innovations in cancer treatment such as robotic surgery or more targeted radiation therapy have not had the anticipated result of reducing sexual dysfunction. Some new and effective cancer treatments, including aromatase inhibitors for breast cancer or chemoradiation for anal cancer also have very severe sexual morbidity. Cancer-related infertility is an issue for younger patients, who comprise a much smaller percentage of total cancer survivors. However, the long-term emotional impact of being unable to have a child after cancer can be extremely distressing. Advances in knowledge about how cancer treatments may damage fertility, as well as newer techniques to preserve fertility, offer hope to patients who have not completed their childbearing at cancer diagnosis. Unfortunately, surveys in industrialised nations confirm that many cancer patients are still not informed about potential changes to their sexual function or fertility, and all modalities of fertility preservation remain underutilised. After cancer treatment, many patients continue to have unmet needs for information about restoring sexual function or becoming a parent. Although more research is needed on optimal clinical practice, current studies suggest a multidisciplinary approach, including both medical and psychosocial treatment options.
