The Quality of Life and Hormonal Disturbances in Testicular Cancer Survivors in Cisplatin Era

Insulin-like Factor 3, Basal and Human Chorionic Gonadotropin-Stimulated Testosterone as Biomarkers to Predict the Effect of Testosterone Replacement in Testicular Cancer Survivors With Mild Leydig Cell Insufficiency

INTRODUCTION

Mild Leydig cell insufficiency affects a substantial proportion of testicular cancer survivors. Previous studies have not shown a beneficial effect of testosterone replacement therapy, however, with a pronounced interindividual effect. Thus, biomarkers identifying the subgroups that might benefit are wanted. We aimed to determine if insulin-like factor 3 (INSL3), basal and human chorionic gonadotropin (hCG)-stimulated testosterone can predict the effect of testosterone replacement therapy in testicular cancer survivors with mild Leydig cell insufficiency.

PATIENTS AND METHODS

We randomized adult testicular cancer survivors with mild Leydig cell insufficiency 1:1 to 12 months of transdermal testosterone replacement therapy (Tostran gel 2%) or placebo. INSL3, basal, and hCG-stimulated testosterone were measured at baseline. Outcomes (glucose, insulin, HbA1C, lipids, blood pressure, and body composition) were measured at baseline, 6 and 12 months. We applied a linear mixed-effect model comparing patients receiving testosterone with placebo in subgroups by biomarker.

RESULTS

We included and randomized 69 patients between October 2016 and February 2018. Patients with INSL3 and hCG-stimulated testosterone concentrations below the median had a -1.7 kg (95% CI: -3.1, -0.4) and -2.0 kg (95% CI: -3.5, -0.6) change in fat mass after 12 months of testosterone replacement therapy compared with placebo. This was not the case in patients with INSL3 and hCG-stimulated testosterone above the median. We did not find any effect of these biomarkers on glucose, insulin, HbA1c, or lipids.

CONCLUSION

Patients with INSL3 and hCG-stimulated testosterone concentrations below the median had decreased fat mass after 12 months of testosterone replacement therapy compared with placebo. It should be evaluated in larger trials if these biomarkers can be used as predictive markers identifying testicular cancer patients with mild Leydig cell insufficiency who might benefit from testosterone substitution.

Goal-Focused Emotion-Regulation Therapy (GET) in Young Adult Testicular Cancer Survivors: A Randomized Pilot Study

BACKGROUND

Young adult testicular cancer survivors experience adverse impacts after treatment. We developed Goal-focused Emotion-regulation Therapy (GET) to improve distress symptoms, emotion regulation, and goal navigation skills.

PURPOSE

This pilot study examined GET versus an active control intervention in young adult survivors of testicular cancer.

METHODS

Seventy-five eligible survivors treated with chemotherapy were randomized to receive GET or Individual Supportive Listening (ISL). Study acceptability, engagement, and tolerability were examined, and intervention fidelity and therapeutic alliance were compared between arms. Preliminary efficacy was evaluated by effect sizes for between-group changes in primary (anxiety and depressive symptoms) and secondary (career confusion, goal navigation, and emotion regulation) outcomes from baseline to immediately and 3-month post-intervention.

RESULTS

Among the 38 men randomized to GET, 81.1% completed all study sessions compared with 82.4% of the 37 men assigned to ISL. Fidelity to the intervention was 87% in GET. Therapeutic alliance wassignificantly higher among those receiving GET versus ISL. Participants exhibited a medium group-by-time effect size with greater reductions in depressive (d = 0.45) and anxiety (d = 0.29) symptoms for those in GET versus ISL, with a similar pattern at 3 months for depressive (d = 0.46) and anxiety (d = 0.46) symptoms.

CONCLUSIONS

GET is a feasible and acceptable intervention for reducing adverse outcomes after testicular cancer for young adults. Observed effect sizes preliminarily suggest meaningful change, though should be interpreted with caution in small samples. GET may be a developmentally-matched behavioral approach to improve psychosocial function in this cancer group.

Epidemiology of Male Hypogonadism

The epidemiology of male hypogonadism has been understudied. Of the known causes of endogenous androgen deficiency, only Klinefelter syndrome is common with a likely population prevalence of greater than 5:10,000 men (possibly as high as 10-25:10,000). Mild traumatic injury might also be a common cause of androgen deficiency (prevalence 5-10:10,000 men), but large, long-term studies must be completed to confirm this prevalence estimation that might be too high. The classic causes of male androgen deficiency-hyperprolactinemia, pituitary macroadenoma, endogenous Cushing syndrome, and iron overload syndrome-are rare (prevalence < 10,000 men).

Semen and serum platinum levels in cisplatin-treated survivors of germ cell cancer

Background

Testicular cancer survivors often have impaired gonadal function possibly related to chemotherapy. Platinum is a heavy metal that can be detected at low levels in serum many years after treatment, it is not known whether platinum also persists in semen and if platinum persistence in semen is associated with impaired fertility.

Methods

Adult cisplatin‐treated testicular cancer survivors were enrolled. High‐Performance Liquid Chromatography‐tandem mass spectrometry was used to measure semen and serum platinum levels. Semen quality and DNA Fragmentation Index (DFI) were assessed.

Results

From 11/2017 to 12/2019, 38 patients (median age 32 years; range: 19–52) were enrolled. Median cumulative cisplatin dose was 301 mg/m² (range: 274–404). Platinum levels were higher in semen than in blood (p = 0.03). Semen platinum levels were not significantly associated with time from last cisplatin dosing (r = −0.34; p = 0.09) nor cumulative dose (r = −0.10, p = 0.63). Sperm concentration was correlated with time from last cisplatin dosing (r = 0.58, p < 0.001) but not with semen platinum level (r = −0.15, p = 0.46). DFI was not significantly associated with time from last cisplatin dosing (r = 0.55, p = 0.08) or semen platinum level (r = −0.32, p = 0.33). In four patients with serial semen samples, platinum level decreased and sperm concentration and motility increased over time.

Conclusions

Platinum is detected in semen of testicular cancer survivors at higher levels than matched blood samples. These preliminary findings may have important implications for the reproductive health of survivors of advanced testicular cancer, further study is needed to assess the relationship between platinum persistence in semen and recovery of fertility postchemotherapy.

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.

Use of Medications for Treating Anxiety or Depression among Testicular Cancer Survivors: A Multi-Institutional Study

BACKGROUND

This study examined sociodemographic factors, cisplatin-related adverse health outcomes (AHO), and cumulative burden of morbidity (CBM_Pt) scores associated with medication use for anxiety and/or depression in testicular cancer survivors (TCS).

METHODS

A total of 1,802 TCS who completed cisplatin-based chemotherapy ≥12 months previously completed questionnaires regarding sociodemographic features and cisplatin-related AHOs [hearing impairment, tinnitus, peripheral sensory neuropathy (PSN), and kidney disease]. A CBM_Pt score encompassed the number and severity of cisplatin-related AHOs. Multivariable logistic regression models assessed the relationship of individual AHOs and CBM_Pt with medication use for anxiety and/or depression.

RESULTS

A total of 151 TCS (8.4%) used medications for anxiety and/or depression. No cisplatin-related AHOs were reported by 511 (28.4%) participants, whereas 622 (34.5%), 334 (18.5%), 287 (15.9%), and 48 (2.7%), respectively, had very low, low, medium, and high CBM_Pt scores. In the multivariable model, higher CBM_Pt scores were significantly associated with medication use for anxiety and/or depression (P < 0.0001). In addition, tinnitus (P = 0.0009), PSN (P = 0.02), and having health insurance (P = 0.05) were significantly associated with greater use of these medications, whereas being employed (P = 0.0005) and vigorous physical activity (P = 0.01) were significantly associated with diminished use.

CONCLUSIONS

TCS with higher CBM_Pt scores had a higher probability of using medications for anxiety and/or depression, and conversely, those who were employed and physically active tended to have reduced use of these medications.

IMPACT

Healthcare providers should encourage TCS to increase physical activity to improve both physical and mental health. Rehabilitation programs should assess work-related skills and provide career development counseling/training.

A 25-year review of advances in testicular cancer: Perspectives on evaluation, treatment, and future directions/challenges

The year 2020 will be remembered for a number of different events, both good and bad. For the journal Urologic Oncology, Seminars and Original Investigations, this year represents the 25th anniversary of its inception and 1st publication. Under the encouragement of Editor-in-Chief Dr. Michael Droller, the collective editorial board has put together a reflection of the progresses made among the spectrum of genitourinary cancers across the entirety of therapeutic disciplines. In this review, we discuss the advances achieved in our knowledge and understanding of testicular germ cell tumors since 1995, and the challenges that lie ahead.

Late adverse effects and quality of life in survivors of testicular germ cell tumour

Currently, ~95% of patients with testicular germ cell tumour (TGCT) are cured, resulting in an increasing number of TGCT survivors. Although cured, these men face potential late adverse effects and reduced quality of life. Survivors face a twofold increased risk of second malignant neoplasms after chemotherapy and radiotherapy, with evidence of dose-dependent associations. For survivors managed with surveillance or treated with radiotherapy, the risk of cardiovascular disease (CVD) is comparable to the risk in the general population, whereas treatment with chemotherapy increases the risk of life-threatening CVD, especially during treatment and after 10 years of follow-up. Other adverse effects are organ-related toxicities such as neuropathy and ototoxicity. Pulmonary and renal impairment in patients with TGCT treated with chemotherapy is limited. Survivors of TGCT might experience psychosocial distress including anxiety disorders, fear of cancer recurrence and TGCT-specific issues, such as sexual dysfunction. Late adverse effects can be avoided in most patients with stage I disease if followed on a surveillance programme. However, patients with disseminated disease can experience toxicities associated with radiotherapy and chemotherapy, and/or adverse effects related to surgery for residual disease. The severity of adverse effects increases with dose of both chemotherapy and radiotherapy. This Review discusses the most recent data concerning the late adverse effects of today's standard treatments for TGCT.

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.

Tadalafil alleviates cisplatin-induced reproductive toxicity through the activation of the Nrf2/HO-1 pathway and the inhibition of oxidative stress and apoptosis in male rats

Male reproductive toxicity is a well-known adverse effect of cisplatin (CIS), an important antineoplastic agent used to control several types of cancers. Tadalafil (TDF), is a long-acting phosphodiesterase-5 (PDE5) inhibitor commonly used as treatment for erectile dysfunction. The aim of this work was to study the possible protective effect of TDF against CIS-induced testicular toxicity in rats and the possible involvement of Nrf2/HO-1 pathway, which demonstrates antioxidant and inflammatory activities utilizing zinc protoporphyrin-IX (ZnPP) as HO-1 inhibitor. Results revealed that TDF attenuated the CIS-induced disturbances in sperm count and activities, normalized the serum testosterone level, improved the CIS-induced changes in epididymal and testicular weights and restored the normal structure of testicular tissues. In addition, TDF upregulated the gene expression levels of Nrf2 and HO-1 and the activity of HO-1 whereas, it reduced the CIS-induced changes in testicular oxidative stress markers and the levels of inflammatory mediators (TNF-α and iNOS). Furthermore, TDF antagonized the CIS-induced increase in testicular gene expression of apoptotic markers caspase-3 and Bax, and the decrease in Bcl-2. However, ZnPP co-administration significantly attenuated all TDF-mediated improvements in CIS-induced testicular toxicity, biochemical changes, and apoptosis. In conclusion, TDF exerts a protective effect against CIS-induced reproductive toxicity in males, through different mechanisms, besides its inhibitory action to PDE5, possibly mediated by the upregulation of Nrf2/HO-1, along with its antioxidant, anti-inflammatory, and anti-apoptotic effects. Hence, the use of TDF represents a promising therapeutic approach to protect the male reproductive system from the harmful toxic effects of CIS.

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.

[Sexual dysfunctions of patients treated with orchidectmoy, chemotherapy and retroperitoneal lymphadenectomy, need for systematic andrological care?]

GOAL

Long-term evaluation of the incidence of sexual dysfunction from patients who were treated by orchidectomy, chemotherapy, and retroperitoneal lymphadenectomy for testicular cancer.

METHODS

In 2018, patients who were treated in two academic hospitals by orchiectomy, chemotherapy, and retroperitoneal lymphadenectomy, and were in complete remission, were included. The patients included in this study filled the survey, which covered aspects of their sexuality (the Male Sexual Health Questionnaire) and answered additional questions, which evaluated psychological impact and modification of their sexuality since the management of their cancer.

RESULTS

Twenty patients have been included, 70% of the patients treated for non-seminomatous germ cell tumor. Mean age was 36.4years±12.1 and the average duration of follow-up was 59months±34. Sexual dysfunction was found in 50% of the patients. Only 10% of the patients could preserve satisfying sexual activity during their treatment. Since the end of their treatment, 16%, 21% and 37% of patients respectively declared high libido loss, lower tumescent erections and persistence of anejaculation. In the end, nearly 70% of these patients wished a dedicated consultation with an urologist with subspecialty in andrology, in order to obtain further information during their care course.

DISCUSSION

These patients have shown multicomponent sexual dysfunction. They could benefit from a new healthcare pathway implying early involvement of andrologist network.

The Evaluation of the Effects of N-Acetylcysteine on Cisplatin-Induced Alterations in Exploratory Activity in Elevated Plus Maze Test in Rats

The aim of this study was to evaluate the potential beneficial effect of N-acetylcysteine (NAC) on cisplatin-induced alterations in anxiety levels in rats, by means of parameters of the exploratory activity obtained in the elevated plus maze (EPM) test. Animals were divided into four groups: control group, cisplatin group (7.5 mg/kg/weekly of cisplatin), N-acetylcysteine group (500 mg/kg/weekly of NAC), and cisplatin plus N-acetylcysteine group (7.5 mg/kg/weekly of cisplatin, and 500 mg/kg/weekly of NAC). After two weeks of treatment, exploratory activity (estimated by means of the number of rearings, head-dippings and the number of total exploratory activity episodes) was significantly reduced in cisplatin group comparing to control values. Although NAC induced no alterations in exploratory activity when applied alone, simultaneous administration with cisplatin resulted in significant attenuation of cisplatin-induced decline in exploratory activity. The exploratory activity gradually decreased in time-dependent manner during five minutes of EPM test in all groups. The results of this study confirmed clear beneficial effect of NAC supplementation against cisplatin- induced neurotoxicity in rats. Antioxidative properties of NAC were manifested through restoration of exploratory activity, confirming that NAC administration can attenuate anxiogenic effect of cisplatin therapy. Those results could recommend NAC supplementation as a potential protection against cisplatin-induced neurotoxicity.

Hypogonadism and Sexual Dysfunction in Testicular Tumor Survivors: A Systematic Review

Testicular tumor is the most common malignancy in men of reproductive age. According to the tumor histology and staging, current treatment options include orchiectomy alone or associated with adjuvant chemo- and/or radiotherapy. Although these treatments have considerably raised the percentage of survivors compared to the past, they have been identified as risk factors for testosterone deficiency and sexual dysfunction in this subgroup of men. Male hypogonadism, in turn, predisposes to the development of metabolic and cardiovascular impairment that negatively affects general health. Accordingly, longitudinal studies report a long-term risk for cardiovascular diseases after radiotherapy and/or cisplatin-based chemotherapy in testicular tumor survivors. The aim of this review was to summarize the current evidence on hypogonadism and sexual dysfunction in long-term cancer survivors, including the epidemiology of cardiovascular and metabolic disorders, to increase the awareness that serum testosterone levels, sexual function, and general health should be evaluated during the endocrinological management of these patients.

Sexual Function and Quality of Life in a National Cohort of Survivors of Bilateral Testicular Cancer

BACKGROUND

Sexual function and quality of life remain unexplored among long-term survivors of bilateral testicular cancer (TC).

OBJECTIVE

To investigate sexual function, fatigue, anxiety, and depression among long-term survivors of bilateral TC (unilateral TC with contralateral germ cell neoplasia in situ [TC+GCNIS] or bilateral TC [BTC]).

DESIGN, SETTING, AND PARTICIPANTS

This was a cross-sectional study of 2479 long-term TC survivors, of whom 126 were treated with contralateral radiotherapy for GCNIS, 93 were treated with bilateral orchiectomy for BTC, and 2260 had unilateral TC (reference group).

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Outcomes were assessed using validated questionnaires at a median time since diagnosis of 17 yr (interquartile range 12-23). Results for survivors of TC+GCNIS and of BTC were compared with those for the reference group. Adjustment was made for age and treatment for disseminated disease.

RESULTS AND LIMITATIONS

The age-adjusted risk of anxiety was significantly higher among BTC survivors (odds ratio 1.7, 95% confidence interval [CI] 1.1-2.8; p=0.002) than in the reference group. Apart from a higher risk of reduced motivation among survivors of TC+GCNIS (β=0.067, 95% CI 0.0013-0.13; p=0.046) there were no significant differences between the groups. Limitations include the low number of cases with symptoms of depression.

CONCLUSIONS

Survivors of BTC had a higher risk of anxiety but did not experience impairment of other aspects of quality of life when compared to survivors of unilateral TC. These results are of importance for evidence-based information on late effects for bilateral TC patients.

PATIENT SUMMARY

We evaluated quality of life and sexual function among long-term survivors of bilateral testicular cancer. Reassuringly, we did not find impaired quality of life apart from a higher risk of anxiety when comparing survivors of bilateral testicular cancer with survivors of unilateral testicular cancer.

Testicular cancer

Testicular cancer is the most common malignancy among men between 14 and 44 years of age, and its incidence has risen over the past two decades in Western countries. Both genetic and environmental factors contribute to the development of testicular cancer, for which cryptorchidism is the most common risk factor. Progress has been made in our understanding of the disease since the initial description of carcinoma in situ of the testis in 1972 (now referred to as germ cell neoplasia in situ), which has led to improved treatment options. The combination of surgery and cisplatin-based chemotherapy has resulted in a cure rate of >90% in patients with testicular cancer, although some patients become refractory to chemotherapy or have a late relapse; an improved understanding of the molecular determinants underlying tumour sensitivity and resistance may lead to the development of novel therapies for these patients. This Primer provides an overview of the biology, epidemiology, diagnosis and current treatment guidelines for testicular cancer, with a focus on germ cell tumours. We also outline areas for future research and what to expect in the next decade for testicular cancer.

Quality of Life in Long-Term Testicular Cancer Survivors With Compensated Leydig Cell Dysfunction

BACKGROUND

Compensated Leydig cell (LC) dysfunction, defined by elevated serum levels of luteinizing hormone (LH) in combination with normal total testosterone levels, is common in testicular cancer (TC) survivors. The association between this condition and quality of life is unknown. We aimed to clarify if TC survivors with compensated LC dysfunction have impaired quality of life.

PATIENTS AND METHODS

In total, 147 long-term TC survivors were included. On the basis of a single measurement of testosterone and LH, compensated LC dysfunction was defined by age-adjusted levels of LH above normal range combined with testosterone levels within the normal range. Quality-of-life outcomes including sexual function, anxiety and depression, fatigue, and overall self-evaluated quality of life were compared between patients with and without compensated LC dysfunction with adjustment for age.

RESULTS

In total, 60 TC survivors had compensated LC dysfunction and 87 TC survivors had normal LC function. TC survivors with compensated LC dysfunction had lower serum levels of total testosterone (11 vs. 13 nmol/L, P = .016). There were no significant differences in the investigated quality-of-life outcomes (anxiety, depression, sexual function, fatigue) between the 2 groups.

CONCLUSION

Compensated LC dysfunction in TC survivors was not associated with symptoms of depression, anxiety, sexual dysfunction, fatigue, or impaired overall self-evaluated quality of life. Limitations include the few cases of symptoms of depression (n = 7). Our findings do not suggest that testosterone substitution is indicated in TC survivors with compensated LC dysfunction.

Sexual Function in a Nationwide Cohort of 2,260 Survivors of Testicular Cancer after 17 Years of Followup

PURPOSE

Evidence on the long-term impact of testicular cancer treatment on sexual function is not clear. Our aim was to estimate the effect of testicular cancer treatment on the risk of sexual dysfunction in long-term survivors of testicular cancer.

MATERIALS AND METHODS

We performed a cross-sectional study of 2,260 long-term survivors of testicular cancer with a median followup of 17 years (IQR 12-24), including 1,098 who underwent orchiectomy alone (surveillance), 788 treated with bleomycin, etoposide and cisplatin alone or post-chemotherapy retroperitoneal surgery, 300 treated with abdominal radiotherapy and 74 who received more than 1 line of treatment. Sexual function was evaluated by the IIEF-15 (International Index of Erectile Function-15) questionnaire. Results were compared between treatment groups using logistic regression analysis with the results on each of the 5 IIEF-15 dimensions as the outcome and treatment as exposure using surveillance as the referent.

RESULTS

The risk of erectile dysfunction was increased in all treatment groups compared to surveillance, including bleomycin, etoposide and cisplatin alone (OR 1.5, 95% CI 1.0-2.1, p <0.05), bleomycin, etoposide and cisplatin with post-chemotherapy surgery (OR 2.1, 95% CI 1.4-3.4, p <0.005), radiotherapy (OR 1.7, 95% CI 1.1-2.5, p <0.05) and more than 1 line of treatment (OR 3.2, 95% CI 1.6-6.3, p <0.005). Orgasmic dysfunction was associated with radiotherapy, bleomycin, etoposide and cisplatin with post-chemotherapy surgery and more than 1 line of treatment.

CONCLUSIONS

Treatment with bleomycin, etoposide and cisplatin, radiotherapy and more than 1 treatment line increased the risk of erectile dysfunction in long-term survivors of testicular cancer compared to surveillance. Patients should be informed about this as part of the information on treatment related late effects.

A systematic review of quantitative observational studies investigating psychological distress in testicular cancer survivors

OBJECTIVE

Testicular cancer (TC) affects young men and may cause psychological distress despite a good prognosis. This systematic review evaluated the prevalence, severity, and correlates of anxiety, depression, fear of cancer recurrence (FCR), and distress in TC survivors.

METHODS

A systematic search of literature published 1977 to 2017 was conducted to find quantitative studies including TC survivor-reported outcomes relevant to review objectives. The quality of included articles was assessed, and a narrative synthesis conducted.

RESULTS

Of 6717 articles identified, 66 (39 good, 20 fair, and 7 poor quality) reporting results from 36 studies were included. Testicular cancer survivors' mean anxiety levels were higher than in the general population, while mean depression and distress were no different. Clinically significant anxiety (≈1 in 5) and to a lesser extent distress (≈1 in 7), but not depression, were more prevalent in TC survivors than the general population. Approximately 1 in 3 TC survivors experienced elevated FCR. Poorer psychological outcomes were more common among TC survivors who were single, unemployed/low socio-economic status, suffering from co-morbidities, experiencing worse symptoms/side effects, and using passive coping strategies.

CONCLUSIONS

Many TC survivors do not experience significant psychological morbidity, but anxiety and FCR are prevalent. Inadequate coping resources (eg, low socio-economic status and social support) and strategies (eg, avoidance) and greater symptoms/side effects were associated with poorer outcomes. Theoretically driven prospective studies would aid understanding of how outcomes change over time and how to screen for risk. Age and gender appropriate interventions that prevent and manage issues specific to TC survivors are also needed.

Long-term toxicity of cisplatin in germ-cell tumor survivors

CONTEXT

Testicular germ-cell tumors (GCT) are highly curable. A multidisciplinary approach, including cisplatin-based chemotherapy has resulted in cure in the majority of patients with GCT. Thus, the life expectancy of survivors will extend to many decades post-diagnosis. Late treatment toxicities associated with cisplatin-based chemotherapy may impact their future health.

OBJECTIVE

To systematically evaluate evidence regarding the long-term toxicity of cisplatin in GCT survivors.

EVIDENCE ACQUISITION

We carried out a critical review of PubMed/Medline in February 2017 according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Identified reports were reviewed according to the Consolidated Standards of Reporting Trials (CONSORT) criteria. Eighty-three publications were selected for inclusion in this analysis.

EVIDENCE SYNTHESIS

Included reports evaluated long-term toxicities of cisplatin-based chemotherapy in GCT survivors. Studies reporting neuro- and ototoxicity, secondary malignancies, cardiovascular, renal and pulmonary toxicities, hypogonadism and infertility were found. Seven studies (8%) reported genetic underpinnings of long-term toxicities and 3 (4%) and 14 (19%) studies correlated long-term toxicities with circulating platinum levels and cumulative dose of cisplatin, respectively. Significant risks for long-term toxicities associated with cisplatin and platinum-based regimens were reported. The cumulative dose of cisplatin and circulating platinum were reported as risk factors. Several single-nucleotide polymorphisms identified patients susceptible to cisplatin compared with wild-type individuals.

CONCLUSIONS

GCT survivors cured with cisplatin-based chemotherapy are at risk for long-term side-effects. Detection of single-nucleotide polymorphisms could be a valuable tool for predicting long-term toxicities.

PATIENT SUMMARY

Herein, this article summarizes the available evidence of long-term toxicity of cisplatin-based chemotherapy in GCT survivors and provide insights from Indiana University.

Hormonal Changes and Sexual Dysfunction

Sexual dysfunction is a common concern for many patients with cancer after treatment. Hormonal changes as a result of cancer-directed therapy can affect both male and female sexual health. This has the potential to significantly impact patients' quality of life, but is underreported and undertreated in the oncology setting. This review discusses commonly reported sexual issues and the role that hormonal changes play in this dysfunction. Although medical and psychosocial intervention strategies exist, there is a clear need for further research to formally develop programming that can assist people whose sexual health has been impacted by cancer treatment.

A randomized double-blind study of testosterone replacement therapy or placebo in testicular cancer survivors with mild Leydig cell insufficiency (Einstein-intervention)

BACKGROUND

Elevated serum levels of luteinizing hormone and slightly decreased serum levels of testosterone (mild Leydig cell insufficiency) is a common hormonal disturbance in testicular cancer (TC) survivors. A number of studies have shown that low serum levels of testosterone is associated with low grade inflammation and increased risk of metabolic syndrome. However, so far, no studies have evaluated whether testosterone substitution improves metabolic dysfunction in TC survivors with mild Leydig cell insufficiency.

METHODS/DESIGN

This is a single-center, randomized, double-blind, placebo-controlled study, designed to evaluate the effect of testosterone replacement therapy in TC survivors with mild Leydig cell insufficiency. Seventy subjects will be randomized to receive either testosterone replacement therapy or placebo. The subjects will be invited for an information meeting where informed consent will be obtained. Afterwards, a 52-weeks treatment period begins in which study participants will receive a daily dose of transdermal testosterone or placebo. Dose adjustment will be made three times during the initial 8 weeks of the study to a maximal daily dose of 40 mg of testosterone in the intervention arm. Evaluation of primary and secondary endpoints will be performed at baseline, 26 weeks post-randomization, at the end of treatment (52 weeks) and 3 months after completion of treatment (week 64).

DISCUSSION

This study is the first to investigate the effect of testosterone substitution in testicular cancer survivors with mild Leydig cell insufficiency. If positive, it may change the clinical handling of testicular cancer survivors with borderline low levels of testosterone.

Clinical significance of androgen secretion disorders in men with a malignancy

Cancer and its treatment can lead in men to testosterone deficiency, accompanied by somatic and mental symptoms. Germ cell tumours and their treatment may disturb the pituitary-gonadal axis, hence leading to significant clinical abnormalities. In some prostate cancer patients, castration, temporary or permanent, is a desired therapeutic condition. Yet, it is burdened with various side effects of complex intensity and significance. Last but not least, patients in the terminal stage of a malignancy present with low testosterone concentrations as a part of anorexia-cachexia syndrome. Oncological management of such patients disturbs their homeostasis, androgen metabolism included, which results in numerous complications and worsens their quality of life. In the present paper, we analysed the frequency and sequelae of testosterone deficiency in some clinical scenarios, on the basis of original papers, meta-analyses and reviews available in PubMed. Androgen secretion disorders in male cancer patients depend on a cancer type, stage and methods of treatment. Number of testicular cancer survivors is increasing, and as a consequence, more patients cope with late complications, testosterone deficiency included. Hormone therapy in prostate cancer patients significantly prolongs survival, and then numerous men experience long-term adverse effects of androgen deficiency. Those, in turn, particularly the metabolic syndrome, may contribute to increased mortality. Androgen deficiency is a part of cancer anorexia-cachexia syndrome. The role of androgen deficiency in cancer patients is still under debate, and further studies are urgently needed to establish appropriate clinical guidelines.

Reproductive hormones and metabolic syndrome in 24 testicular cancer survivors and their biological brothers

Testicular cancer survivors have impaired gonadal function and increased risk of metabolic syndrome when compared to healthy controls. However, because of the fetal etiology of testicular cancer, familial unrelated healthy men might not be an optimal control group. The objective of this study was to clarify if testicular cancer survivors have impaired gonadal function and increased risk of metabolic syndrome when compared to their biological brothers. A cross-sectional study of testicular cancer survivors (ClinicalTrials.gov number, NCT02240966) was conducted between 2014 and 2016. Of 158 testicular cancer survivors included, 24 had a biological brother who accepted to participate in the study. Serum levels of reproductive hormones and prevalence of metabolic syndrome according to International Diabetes Federation Criteria and National Cholesterol Education Program (Adult Treatment Panel III) criteria comprised the main outcome measures of the study. Median age was similar in testicular cancer survivors and their biological brothers [44 years (IQR 39-50) vs. 46 (40-53) years respectively (p = 0.1)]. In testicular cancer survivors, follow-up since treatment was 12 years (7-19). Serum levels of luteinizing hormone and follicle-stimulating hormone were elevated (p ≤ 0.001), while total testosterone, free testosterone, inhibin B and anti-Müllerian hormone were lower (p ≤ 0.001) in testicular cancer survivors than in their biological brothers. The prevalence of metabolic syndrome was similar and apart from HDL-cholesterol, which was lower in testicular cancer survivors (p = 0.01); there were no differences in the individual components of the metabolic syndrome between testicular cancer survivors and their brothers. In conclusion, gonadal function was impaired in testicular cancer survivors, while we did not detect any difference in the prevalence of metabolic syndrome between testicular cancer survivors and their biological brothers.

Dynamics of hormonal disorders following unilateral orchiectomy for a testicular tumor

Testicular tumors and their treatment interfere with homeostasis, hormonal status included. The aim of the study was to evaluate hormonal disorders of the pituitary–gonadal axis in men treated for testicular tumors. One hundred twenty-eight men treated for a unilateral testicular tumor at our institution were included. The hormonal status was prospectively evaluated in 62 patients before orchiectomy, 120 patients 1 month after orchiectomy and 110 patients at least 1 year after the treatment. The concentrations of human chorionic gonadotropin (hCG), testosterone (T), estradiol, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and prolactin were measured. The clinically significant testosterone deficiency was defined either as testosterone <2.31 ng/mL or testosterone within the range of 2.31–3.46 ng/mL but simultaneous with T/LH ratio ≤1. Changes in hormone levels were significant: LH and FSH rose in the course of observation, and the concentration of hCG, testosterone, estradiol decreased. PRL concentration was the lowest at 1 month after orchiectomy. In multivariate analysis, the risk of the clinically significant testosterone deficiency was 0.2107 (95% CI 0.1206–0.3419) prior to orchiectomy, 0.3894 (95% CI 0.2983–0.4889) 1 month after surgery and 0.4972 (95% CI 0.3951–0.5995) 1 year after the treatment. The estradiol concentration was elevated in 40% of patients with recently diagnosed testicular cancer and that was correlated with a higher risk of testosterone deficiency after the treatment completion. Hormonal disorders of the pituitary–gonadal axis in men treated for testicular tumors are frequent. The malignant tissue triggers paraneoplastic disorders that additionally disturb the hormonal equilibrium.

Cisplatin-Induced Nephrotoxicity; Protective Supplements and Gender Differences

Cisplatin (CDDP) has been widely used as a chemotherapeutic agent for solid tumors. The most common side effect of CDDP is nephrotoxicity, and many efforts have been made in the laboratory and the clinic to employ candidate adjuvants to CDDP to minimize this adverse influence. Many synthetic and herbal antioxidants as well as trace elements have been investigated for this purpose in recent years and a variety of positive and negative results have been yielded. However, no definitive supplement has so far been proposed to prevent CDDP-induced nephrotoxicity; however, this condition is gender related and the sex hormone estrogen may protect the kidney against CDDP damage. In this review, the results of research related to the effect of different synthetic and herbal antioxidants supplements are presented and discussed with suggestions included for future work.

Longitudinal Changes in Serum Levels of Testosterone and Luteinizing Hormone in Testicular Cancer Patients after Orchiectomy Alone or Bleomycin, Etoposide, and Cisplatin

BACKGROUND

Controversy exists whether Leydig cells recover after testicular cancer (TC) treatment or whether premature hormonal aging will occur.

OBJECTIVE

Evaluate serial changes in total testosterone (TT) and luteinizing hormone (LH) in patients treated with orchiectomy alone (Stage I) or combination chemotherapy with bleomycin, etoposide, and cisplatin (BEP).

DESIGN, SETTINGS, AND PARTICIPANTS

Changes in TT and LH were investigated during 5-yr follow-up (Stage I: n=75, BEP: n=81). A selected group of TC patients with mild Leydig cell dysfunction (LH ≥ 8 IU/l) were followed for a longer period (Stage I: n=20, BEP: n=23). An age-matched control group of 839 healthy men served as controls for TT and LH levels.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Changes in age-adjusted TT and LH were evaluated separately in each treatment group with univariate linear regression analysis. The proportion of patients initiating testosterone substitution during follow-up was calculated.

RESULTS AND LIMITATIONS

In the 75 Stage I patients there were no significant changes in LH and TT, while in the 81 BEP treated patients there was a significant decline in LH during follow-up (-24.2 percentage point/yr, 95% confidence interval: -38.5 to -9.9, p=0.001). In total, 11% of Stage I patients and 15% of BEP-treated patients initiated testosterone substitution. In the 23 BEP-treated patients with mild Leydig cell dysfunction there was a significant decline in age-adjusted TT (-0.9 percentage point/yr, 95% confidence interval: -1.8 to -0.04, p=0.04), while in the 20 Stage I patients there were no significant changes in age-adjusted LH and TT. Limitations include the retrospective study design.

CONCLUSIONS

TT remained stable during 5-yr follow-up in TC patients treated with orchiectomy alone or BEP. BEP-treated patients with mild Leydig cell dysfunction during follow-up were at risk of long-term testicular failure and evaluation of Leydig cell function beyond follow-up should be considered in this group of patients.

PATIENT SUMMARY

This study shows that the majority of testicular cancer survivors had stable testosterone levels after treatment for testicular cancer. However, 11-15% of patients needed testosterone substitution after treatment.

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.

Anxiety and depression in long-term testicular germ cell tumor survivors

OBJECTIVE

Despite a good prognosis, the typically young age at diagnosis and physical sequelae may cause psychological distress in germ cell tumor survivors. We aimed to determine the frequency of anxiety and depression and analyze the impact of demographic and disease-related factors.

METHOD

We enrolled N=164 testicular germ cell tumor survivors receiving routine follow-up care at the University Cancer Center Hamburg and a specialized private practice (mean, 11.6 years after diagnosis). Patients completed the Generalized Anxiety Disorder Screener-7, the Patient Health Questionnaire-9 and the Memorial Symptom Assessment Scale-Short Form.

RESULTS

We found clinically significant anxiety present in 6.1% and depression present in 7.9% of survivors. A higher number of physical symptoms and having children were significantly associated with higher levels of both anxiety and depression in multivariate regression analyses controlling for age at diagnosis, cohabitation, socioeconomic status, time since diagnosis, metastatic disease and relapse. Younger age at diagnosis and shorter time since diagnosis were significantly associated with higher anxiety.

CONCLUSION

Although rates of clinically relevant anxiety and depression were comparably low, attention toward persisting physical symptoms and psychosocial needs related to a young age at diagnosis and having children will contribute to address potential long-term psychological distress in germ cell tumor survivors.

Testosterone deficiency and quality of life in Australasian testicular cancer survivors: a prospective cohort study

This is the first prospective study in a contemporary Australian/New Zealand population to determine the prevalence of testosterone deficiency in testicular cancer survivors at 12 months from treatment, and any association with poorer quality of life. Hormone assays from 54 evaluable patients in a prospective cohort study revealed biochemical hypogonadism in 18 patients (33%) and low-normal testosterone in 13 patients (24%). We found no association between testosterone levels and quality of life (all P > 0.05). Hypogonadal patients should be considered for testosterone replacement to prevent long-term morbidity.

Quality of life among testis cancer survivors

BACKGROUND

As the most common cancer among males in late adolescence and early adulthood and as a disease with a 5-year relative survival rate of 96%, testis cancer has many survivors who live many years during which chronic toxicities may impair their quality of life.

METHODS

In this review, I aimed to summarize the most relevant literature on quality of life among testis cancer survivors identified via PubMed literature search between 1990 and 2015.

RESULTS

Survivors of testis cancer experience an overall quality of life (QOL) that is not measurably different from that of men of the same age in the general population. Nonetheless, testis cancer and its treatments can result in a variety of long-term conditions that affect QOL. These include peripheral neuropathy, hearing loss, tinnitus, fatigue, and Raynaud-like phenomenon. Exercise interventions have been shown to improve fatigue and overall QOL in cancer survivors, and there is evidence that psychosocial and mind-body interventions may also be beneficial. Pharmacological interventions have not been shown to be helpful for cancer-related fatigue, hearing loss, or neuropathy.

CONCLUSIONS

Testis cancer survivors should be asked about symptoms related to the conditions above and referred to specialists as indicated. Survivors complaining of fatigue should be encouraged to adopt a regular program of aerobic exercise.

Orchiectomy and radiotherapy for stage I-II testicular seminoma: a prospective evaluation of short-term effects on body image and sexual function

INTRODUCTION

Orchiectomy followed by infradiaphragmatic radiotherapy is a common treatment for stage I-II testicular seminoma. Long-term effects of orchiectomy and radiotherapy for testicular seminomas on body image and sexual function have been reported; however, few data are available on short-term effects. Patients are usually of reproductive age and sexually active; therefore, short-term effects on body image and sexual function should also be studied.

AIMS

To prospectively evaluate short-term effects of orchiectomy and radiotherapy on body image and sexual function in testicular seminoma patients.

METHODS

Questionnaires on body image and sexual function were prospectively distributed to all testicular seminoma patients treated between 1999 and 2013. The questionnaire distributed prior to radiotherapy was returned by 161 patients; 133 (82%) returned the second after 3 months, and 120 (75%) completed the questionnaire after 6 months.

MAIN OUTCOME MEASURES

Body image and sexual function as assessed by a Dutch questionnaire on body image and sexuality after radiotherapy and orchiectomy.

RESULTS

Median age was 36 years (range 18-70). After orchiectomy, 48% expressed fertility concerns, and 61% reported their body had changed. Six months after treatment, erectile rigidity was significantly decreased compared with prior to radiotherapy (P = 0.016), and 23% reported decreased sexual interest, activity, and pleasure. Changes in body image were significantly associated with decreased sexual interest, pleasure, and erectile function. Even though 45% reported that treatment negatively affected their sexual life, the number of sexually active patients remained stable at 91%. [Correction added on 12 November 2014, after first online publication: 'prior radiotherapy' was corrected to 'prior to radiotherapy'.]

CONCLUSIONS

Short-term effects of treatment included fertility concerns and changes in body image. Reported erectile rigidity was significantly decreased after 6 months, as were sexual interest, activity, and pleasure. Disease and treatment had negative effects on sexual life, and changes in body image were associated with sexual dysfunction. Therefore, body image and sexual functioning should be addressed at an early stage in order to offer adequate treatment and counseling.

Antidepressants and testicular cancer

PURPOSE

Re-examine association of fluoxetine and paroxetine with risk of testicular cancer noted in drug screening, with 4 years more follow-up and expanded study of these and other antidepressant drugs.

METHODS

In the Kaiser Permanente Medical Care Program in Northern California, 906 men with testicular cancer diagnosed August 1996-December 2010 were compared with 38,253 matched controls with race/ethnicity recorded regarding receipt of antidepressant drugs at least 2 years before diagnosis or control index date. Analyses emphasized duration of use and histological subgroups.

RESULTS

With control for race/ethnicity and use of other antidepressant drugs, odds ratios (OR) and 95 % confidence intervals (CI) for associations with testicular cancer were as follows: fluoxetine 1.22 (0.88-1.71), paroxetine 1.19 (0.78-1.83), and 1.21 (0.92-1.58) for all serotonin reuptake inhibitors. There was no statistically significant association with risk of all testicular cancers or their histological subtypes for any individual drug or for tricyclics or all antidepressants combined except for citalopram with all testicular cancers 2.55 (1.43-4.52) and those of mixed histology 4.36 (1.50-12.68) and nefazodone with embryonal cancers 9.79 (1.85-51.81). These could readily be chance findings in the context of the many analyses that were performed. Duration of use was not associated with risk of the drugs and drug groups with sufficient numbers of exposed cases for analysis.

CONCLUSIONS

We found little evidence to support a testicular carcinogenic effect of fluoxetine, paroxetine, or other antidepressant drugs, but a weakly positive association is not ruled out. The signals in prior screening may have been due to chance and/or uncontrolled confounding.

Sperm counts and endocrinological markers of spermatogenesis in long-term survivors of testicular cancer

Background:

The objective of this study was to assess markers of spermatogenesis in long-term survivors of testicular cancer (TC) according to treatment, and to explore correlations between the markers and associations with achieved paternity following TC treatment.

Methods:

In 1191 TC survivors diagnosed between 1980 and 1994, serum-follicle stimulating hormone (s-FSH; n=1191), s-inhibin B (n=441), and sperm counts (millions per ml; n=342) were analysed in a national follow-up study in 1998–2002. Paternity was assessed by a questionnaire.

Results:

At median 11 years follow-up, 44% had oligo- (<15 millions per ml; 29%) or azoospermia (15%). Sperm counts and s-inhibin B were significantly lower and s-FSH was higher after chemotherapy, but not after radiotherapy (RT), when compared with surgery only. All measures were significantly more abnormal following high doses of chemotherapy (cisplatin (Cis)>850 mg, absolute cumulative dose) compared with lower doses (Cis ⩽850 mg). Sperm counts were moderately correlated with s-FSH (−0.500), s-inhibin B (0.455), and s-inhibin B : FSH ratio (−0.524; all P<0.001). All markers differed significantly between those who had achieved post-treatment fatherhood and those with unsuccessful attempts.

Conclusion:

The RT had no long-term effects on the assessed markers of spermatogenesis, whereas chemotherapy had. At present, the routine evaluation of s-inhibin B adds little in the initial fertility evaluation of TC survivors.

Long-term and late effects of germ cell testicular cancer treatment and implications for follow-up

Germ cell testicular cancer (TC) represents a malignancy with high cure rates. Since the introduction of cisplatin-based chemotherapy in the late 1970s, the 5-year survival rate has increased considerably, and it is currently above 95%. Because TC is usually diagnosed before the age of 40 years, these men can expect to live for another 40 to 50 years after being successfully treated. This success, however, is hampered by an increased risk of long-term and late effects of treatment. Secondary malignant neoplasms and cardiovascular disease represent the most common potentially life-threatening late effects, typically occurring more than 10 years after treatment. Other long-term effects include pulmonary toxicity, nephrotoxicity, neurotoxicity, decreased fertility, hypogonadism, and psychosocial problems. The incidence and time to onset of these various adverse effects vary according to treatment type and intensity. There is still little knowledge about underlying mechanisms and genetic susceptibility of the various adverse effects. Apart from treatment burden, it is not yet possible to identify patients who are at high risk for certain late effects after TC treatment. In this clinical review, we present the current status regarding different somatic and psychosocial long-term late effects after treatment for TC, based on Medline searches and our own research. Moreover, we postulate recommendations for general medical evaluations that should begin after treatment is completed and continue during follow-up.

Health-related quality of life, depression, and sexual function in testicular cancer survivors in a developing country: a Serbian experience

PURPOSE

The aims of this study were to assess health-related quality of life (HRQoL), depression, adverse physical symptoms, and sexual function within Serbian long-term testicular cancer survivors (TCS) and to address cultural specificity.

METHODS

This is a cross-sectional study involving 202 TCS, followed up after platinum-based chemotherapy. The HRQoL was measured using the Short Form 36 and the European Organization for Research and Treatment of Cancer Quality of Life questionnaire. The Beck Depression Inventory (BDI) was used to explore general depressive status while sexual function was assessed using a nine-item questionnaire.

RESULTS

The mean follow-up time since treatment was 47.3 ± 26.8 months. The highest values of the SF-36 scales were obtained for physical functioning, and the lowest SF-36 values were obtained for vitality. Age of patients and BDI scores statistically significantly influenced total quality of life. The mean score of the whole sample on the BDI-II was 4.0. Age is the only statistically significant risk factor for the development of depression. A total of 27.3% TCS reported decreased sexual function compared to the period before treatment. Any level of impairment of erectile function was reported by 20.8% patients and problems with ejaculation by 25.7% patients. Loss of desire was reported by 17.3% TCS. The presence of sexual problems statistically significantly lowered scores of SF-36 domains.

CONCLUSION

Sexual problems seriously impaired HRQoL in TCS. Additionally, HRQoL was also affected by age, depression, and fatigue. Serbian TCS achieved high levels of SF-36 scores, and these results are comparable to studies conducted in developed countries.
