Short- and long-term morbidity after treatment for testicular cancer

Impact of a one-year supervised physical activity program on long-term cancer-related fatigue and mediating effects of the gut microbiota in metastatic testicular cancer patients: protocol of the prospective multicentre, randomized controlled phase-III STARTER trial

BACKGROUND

Testicular germ cell tumours (TGCTs) are the most common malignancy in men aged 15-40 years, with increasing incidence worldwide. About 33 ~ 50% of the patients present with metastatic disease at diagnosis. TGCT survivors experience short- and long-term sequelae, including cancer-related fatigue (CRF). Physical activity (PA) has established effects on reducing CRF and other sequelae and improving health-related quality of life (HRQoL). However, its impact on TGCT survivors has so far received little attention. The gut microbiota plays a crucial role in various physiological functions, including cognition and metabolism, and may mediate the effects of PA on CRF and other sequelae, but this has not been investigated in randomized controlled trials.

METHODS

This national, multicentre, phase-III trial will evaluate the impact of a one-year supervised PA program on CRF and other short- and long-term sequelae in metastatic TGCT patients receiving cisplatin-based chemotherapy combined with etoposide+/-bleomycin. It will also investigate potential mediating effects of the gut microbiota and its metabolites involved in the gut-brain axis on the relationship between PA and CRF and other sequelae. A total of 236 men ≥ 18 years of age with metastatic TGCT (seminoma and non-seminoma) will be enrolled before starting first-line chemotherapy in several French hospitals. The primary (CRF) and secondary (cognitive/psychological/metabolic sequelae, HRQoL, etc.) outcomes and gut microbiota and relevant metabolites will be assessed at inclusion, during and at the end of the one-year intervention, and annually until 10 years since inclusion to assess long-term sequelae, more specifically CRF, cardiovascular toxicities, and second primary cancer occurrence in this population.

DISCUSSION

This trial will provide comprehensive and novel insights into the effects of a long-term supervised PA program on CRF and other sequelae in metastatic TGCT patients receiving first-line chemotherapy. It will also contribute to understanding the potential role of the gut microbiota and its metabolites in mediating the effects of PA on these outcomes. The findings of this study will help the development of effective PA interventions to improve the health of TGCT survivors and may have implications for other cancer populations as well.

TRIAL REGISTRATION

The study was registered on ClinicalTrials.gov (NCT05588700) on 20 Oct. 2022.

Distress, problems and unmet rehabilitation needs after treatment for gynecological cancer

INTRODUCTION

The prevalence of distress, problems and need for rehabilitation among women treated for gynecological cancer is largely unknown. The aims of this study were to examine the prevalence of distress, problems and unmet rehabilitation needs in the first years after treatment for gynecological cancer.

MATERIAL AND METHODS

Women treated for gynecological cancer within the last 2 years were invited. Participants responded to the National Comprehensive Cancer Network Distress Thermometer and Problem List measuring distress and problems. They also answered a questionnaire regarding physical endurance, muscle strength, and need for rehabilitation services.

RESULTS

Of 114 eligible women, 92 (81%) agreed to participate. Mean time since last treatment was 7.6 months (range 0-24.5 months). A total of 57% of the participants reported distress. The four most common problems reported were fatigue (58%), tingling in hands/feet (54%), worry (53%), and problems with memory/concentration (50%). Problems associated with distress were: dealing with partner, all emotional problems (i.e. depression, fears, nervousness, sadness, worry, and loss of interest in usual activities), appearance, memory/concentration, pain, sex, sleep, and problems with physical endurance and muscle strength. Fifty-two per cent reported unmet needs for rehabilitation services. Women with distress reported more unmet rehabilitation needs than those in the non-distressed group.

CONCLUSIONS

The prevalence of distress in this population of women treated for gynecological cancer was high. Having a high number of problems and having unmet needs for rehabilitation services were both associated with distress. Hence, measurement of distress seems to be helpful when assessing the need for rehabilitation services.

Outcome of testicular non-seminomatous germ cell tumours: report from a tertiary cancer centre in eastern India

Non-seminomatous germ cell tumour (NSGCT) is a rare but highly curable malignancy. The literature on the management and outcomes of NSGCT is scarce from India. Here, we report the demography and treatment outcomes of NSGCT treated at our centre. This is a retrospective analysis of testicular and retroperitoneal NSGCT patients treated from March 2011 to December 2019. Patients were staged appropriately with imaging, pre- and post-operative tumour marker. Patients received stage adjusted adjuvant treatment after high inguinal orchiectomy. Patients with advanced disease were risk stratified as per International Germ Cell Cancer Collaborative Group (IGCCCG) classification. A total of 100 patients were treated with a median age of 28 years (Range: 18–51). Primary site was testis in 92 and retroperitoneum in 8 patients. Testicular violation was present in 17 (18%) patients. The stage of the disease was I in 32, II in 19 and III in 49 patients, respectively. IGCCCG risk groups were good in 29 (46%), intermediate in 13 (21%) and poor in 21 (33%) patients. Eleven patients (24%) underwent retroperitoneal lymph node dissection amongst 45 with post-chemotherapy residual disease. After a median follow-up of 26.6 months (range: 2.2–100.7), 3-year event-free survival and overall survival (OS) were 70.7% ± 5.6% and 78.2% ± 5.4%, respectively. S3 tumour marker (p = 0.01) and non-pulmonary visceral metastasis (p < 0.001) emerged as independent poor prognostic factors for OS in multivariate analysis. To conclude, testicular NSGCT has very high cure rate. Two-third patients present with advanced disease and one-third of them had poor risk disease. S3 tumour marker and non-pulmonary visceral metastasis are poor risk factors for OS.

Long-term Testis Cancer Survivors in Canada-Mortality Risks in a Large Population-based Cohort

BACKGROUND

Testis cancer (TC) patients are young with excellent cancer prognosis. Hence, the risk of late-onset treatment-related morbidity and mortality is of concern due to longer survival after treatment.

OBJECTIVE

We set to characterize long-term survival of TC patients through a Canadian population dataset.

DESIGN SETTING AND PARTICIPANTS

We used a population-based dataset, the Canadian Census Health and Environment Cohort (CanCHEC), to identify individuals diagnosed with TC between 1991 and 2010. We compared them with all other male individuals without TC.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The primary outcome was mortality due to cardiovascular disease (CVD) or nontesticular malignancy. Mann-Whitney or chi-square test was used where applicable. Data were analyzed using a Cox proportional hazard model with and without matching.

RESULTS AND LIMITATIONS

We identified 1950 individuals with TC. We compared them with 1 300 295 men with no TC. There were 335 deaths in the study group during the study period (17.2%) with a mean follow-up of 19.6 yr. TC patients were at increased risk of death from secondary malignancies (hazard ratio [HR] 1.63, 95% confidence interval [CI] 1.39-1.91; p < 0.0001) with specific risks for hematologic neoplasms (HR 3.86, 95% CI 2.78-5.37; p < 0.001) and other malignancies (HR 2.41, 95% CI 1.76-3.29; p < 0.001). Gastrointestinal, hematologic, and respiratory toxicities were the most common secondary malignancies leading to death. When stratified according to histology, nonseminoma (NS) patients were at significantly increased risk of death from CVD (HR 2.03, 95% CI 1.27-3.25; p = 0.0032). Individuals with seminoma were at increased risk of death from other nontestis neoplasms (HR 1.46, 95% CI 1.17-1.82; p = 0.0007), specifically hematologic neoplasms (HR 2.09, 95% CI 1.18-3.72; p = 0.0118).

CONCLUSIONS

NS patients are at increased risk of CVD-related death, whereas seminoma patients are at increased risk of death from non-testis-related malignancies.

PATIENT SUMMARY

We report long-term mortality following diagnosis of testis cancer. Nonseminoma patients have an increased risk of death from cardiovascular disease, while seminoma patients have an increased risk of death from secondary malignancies.

Organ-Sparing Surgery in Testicular Tumor: Is This the Right Approach for Lesions ≤ 20 mm?

Background: This study was conducted in order to analyze factors predicting malignancy in patients undergoing organ-sparing surgery (OSS) for small testicular lesions. Methods: Patients with small (≤20 mm) marker-negative clinical stage I testicular tumors were managed by OSS with tumor enucleation and frozen section examination (FSE) for the past 15 years at our institution. Benign and malignant cases were compared, focusing on preoperative and postoperative lesion sizes. Results: Eighty-nine patients were enrolled in this retrospective study. Ten (11.2%) of them were treated for synchronous bilateral tumors. Sixty-seven (67.7%) of ninety-nine lesions were benign, confirming a high concordance rate (98%) between FSE and final histology. Patients with benign tumors were significantly older than patients with malignant tumors (p = 0.026), and benign tumors were detected more frequently during urologic work-up of hormone disorders (p = 0.001). Preoperative tumor size was a strong predictor of malignancy (area under the curve (AUC) = 0.726; p < 0.001). According to the Youden index, the best cutoff to predict tumor dignity was 13.5 mm, resulting in a sensitivity and specificity of 53% and 85%, respectively. No cases of local recurrence or distant metastasis were confirmed after a median follow-up of 42 months. Conclusion: Our findings are consistent with previous reports, supporting an OSS approach in small testicular tumors whenever possible. Most tumors ≤ 20 mm were benign, and in the case of malignancy, OSS with FSE and consecutive orchiectomy is oncologically safe due to the high concordance rate of FSE and final histology, thus preventing a two-stage procedure.

The impact of age at orchiopexy on testicular cancer outcomes

PURPOSE

To estimate how many boys with UDT must undergo orchiopexy to prevent one case of TC, one death from TC and one exposure to TC treatment beyond radical orchiectomy as compared to being treated at an older age.

METHODS

This retrospective study utilized data from a 2007 Swedish study of males who underwent orchiopexy for UDT (Pettersson et al.). TC incidence for boys undergoing orchiopexy for UDT was assessed based on the age at orchiopexy (0-6 years, 7-9 years, 10-12 years, 13-15 years). The incidence of TC in each age cohort was calculated and used to determine the number needed to treat (NNT) for each age group using assumptions based on published TC outcomes.

RESULTS

For an index patient ≤ 6 years, 372 boys need to undergo orchiopexy to prevent a single case of TC, 1488 boys to prevent exposure to TC therapy beyond radical orchiectomy, and 5315 boys to prevent a single TC-related death compared to treatment at an older age.

CONCLUSION

While there is evidence supporting benefits of early orchiopexy, the NNT to affect TC outcomes is very high. Even those with delayed orchiopexies have low risk for TC poor outcomes. This information can be used when counseling patients and families faced with UDT about the risks related to TC, especially with comorbidities.

Psychosocial Issues in Long-Term Survivors of Testicular Cancer

Testicular cancer is the most frequent tumor in young males aged 15-39 years. As cure rates are currently around 90%, the prevalence of survivors is increasing. However, a disease-free condition does not necessarily correspond to a life free of physical and psychosocial health problems. The aim of this review was to explore psychosocial morbidity among testicular cancer survivors. A literature search was conducted in three electronic databases (PubMed, Medline, and Embase). The results of the search on cancer survivors were then combined with those of the search on psychosocial concerns and work performance. Eighty-four publications met the inclusion criteria. Physical, psychological, work-related problems and changing perspectives about work and life in general influenced life and career decisions among testicular cancer survivors. Individual health, sexual relationships and work problems, affect several important aspects of survival and significantly influence the QoL of long-term survivors.

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.

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 outcomes following post-operative radiotherapy for Stage I/II testicular seminoma - an Australasian single-institution experience

INTRODUCTION

The aim of the study is to review the long-term oncological outcomes and adverse effects of post-operative radiotherapy (PORT) for Stage I/II seminoma patients in an Australian radiation treatment centre.

METHODS

This is a retrospective study of 125 patients with Stage I/II seminoma treated with PORT at the Alfred Health Radiation Oncology Service between 1992 and 2013. Patients were linked to the Victorian Cancer Registry to enable confirmation of survival and diagnosis of secondary malignancies (SM). The relapse-free survival (RFS), testicular-cancer-specific survival (TCSS), overall survival (OS) and SM-free survival (SMFS) were estimated with Kaplan-Meier methods.

RESULTS

The median age at diagnosis was 36 (range 20-62). The median time between diagnosis and PORT was 1.6 months (range: 0.5-4.5). Fifty patients (40%) had PORT to the para-aortic (PA) target alone, while the remaining had PORT to PA and ipsilateral or bilateral iliac lymph nodes. There were no acute adverse effects requiring admission. The median follow-up after PORT was 7.8 years (range = 0.1-19.1). There were two relapses, both of which occurred within 1 year of PORT (estimated 10-year RFS = 98.4%). Five deaths were reported, none of which were testicular cancer-related death (estimated 10-year TCSS = 100%, 10-year OS = 97.3%). There were seven SM (one lower lip cancer, one upper shoulder melanoma, one mesothelioma, two prostate cancer, one acute myeloid leukaemia and one contralateral testicular seminoma) reported in six patients, with estimated 10-year SMFS of 92.9%.

CONCLUSION

Our series confirms excellent oncological outcomes among patients with Stage I/II seminoma treated with PORT, with uncommon occurrence of SM.

Lower cognitive performance and white matter changes in testicular cancer survivors 10 years after chemotherapy

OBJECTIVE

Chemotherapy (CT) is associated with adverse effects on cognition. Only few studies have investigated cognition in testicular cancer (TC) patients and studies on very late effects of CT on cognition are absent. Further, brain changes in relation to treatment have not been investigated in TC. The objective of the present study is to compare psychosocial functioning, cognitive performance and brain (micro)structure following surgery and CT for TC, against surgery (S)-only.

METHODS

Twenty-eight CT (43.1±7.5 y) and 23 S-only (48.2±9.5y) TC survivors on average 14 yr post-treatment were examined using questionnaires, neurocognitive tests, and 3T-MRI [Diffusion Kurtosis Imaging (DKI), T1-weighted and Fluid Attenuated Inversion Recovery]. A multivariate cognitive performance score (Mahalanobis distance) was calculated to indicate the grade of cognitive performance. Kurtosis parameters, gray matter, and white matter (WM) volume were calculated from MRI data.

RESULTS

Overall, the CT group showed lower cognitive performance (5.35±1.7) compared with the S-only group (4.4±0.9; P=0.03; d=0.70). Further, TC patients reported more memory problems after CT. DKI revealed a significantly higher radial kurtosis after CT in several anterior and posterior brain areas (P<0.05, corrected), but this was unrelated to cognitive performance.

CONCLUSIONS

This cross-sectional study suggests that men receiving CT for TC are at risk for long-term lower cognitive performance. Although CT affected WM microstructure, this was unrelated to cognitive performance. More extensive, preferably prospective studies are warranted to confirm these results and to provide more insight into the possible mechanisms behind the observed cognitive sequelae after treatment for TC.

Dismantling the present and future threats of testicular cancer: a grounded theory of positive and negative adjustment trajectories

PURPOSE

Testicular cancer commonly affects men in the prime of their lives. While survival rates are excellent, little previous research has examined men's experiences of adjustment to survivorship. We aimed to explore this issue in younger testicular cancer survivors.

METHODS

In-depth qualitative interviews were conducted with testicular cancer survivors over two time points approximately 6 months apart in the year following treatment completion. Interviews were analysed using a grounded theory approach.

RESULTS

The sample included 18 testicular cancer survivors between 22 and 44 years (mean age 34). A grounded theory was developed, which explained the process of positive adjustment over the first year following the treatment completion in terms of men's ability to dismantle the present and future threats of cancer, involving the key transitions of gaining a sense of perspective and striving to get on with life and restore normality. These were facilitated by six key processes. The processes that explained a negative adjustment trajectory are also presented.

CONCLUSIONS

These findings contribute to the understanding of the psychosocial impact of testicular cancer on younger men's lives and have implications for the provision of support to testicular cancer survivors. Further investigation into the feasibility of one-on-one peer support interventions is warranted, as well as informal support that respects men's desire for independence.

IMPLICATIONS FOR CANCER SURVIVORS

Understanding the processes involved in adjustment highlights ways in which health professionals can offer support to those struggling to adjust through challenging illness beliefs, encouraging emotional disclosure and facilitating peer mentoring.

Development and qualitative evaluation of a self-management workshop for testicular cancer survivor-initiated follow-up

PURPOSE/OBJECTIVES

To describe the needs of testicular cancer survivors, develop a nurse-led workshop, and explore the experience of participation.

RESEARCH APPROACH

A systematic intervention development process was used to design a self-management workshop for cancer survivors, which then was evaluated qualitatively.

SETTING

Outpatient clinic in England.

PARTICIPANTS

26 healthcare professionals, charity workers, family members, and testicular cancer survivors participated in the intervention development process. Six testicular cancer survivors attended the workshop and participated in the postintervention focus group discussion.

METHODOLOGIC APPROACH

Ten participants, including four survivors, completed the initial needs assessment interviews. Twenty-six participants then rated the identified needs on two dimensions: importance to self-management and changeability via a self-management intervention. Literature review and expert consultation were used to identify potential workshop components. To explore the experience of attending the intervention, six testicular cancer survivors who participated in the nurse-led workshop were interviewed six weeks later.

FINDINGS

The workshop was well received by participants, who appreciated the goal-setting and information provision activities. The men also felt that they had benefited from the experience of being in the group.

CONCLUSIONS

Testicular cancer survivors had unmet post-treatment needs. The systematic intervention development method led to an evidence-based workshop to address those needs. Men reported benefits from attending the workshop, which may help maintain and improve health.

INTERPRETATION

Nurse-led workshops can address the current unmet needs of testicular cancer survivors.

KNOWLEDGE TRANSLATION

Testicular cancer survivors may require support with health information, maintaining psychological health, and monitoring cancer symptoms. Survivors also need help planning and maintaining an active lifestyle. In addition, a brief workshop approach to intervention delivery is acceptable to testicular cancer survivors.

Molecular characteristics of malignant ovarian germ cell tumors and comparison with testicular counterparts: implications for pathogenesis

This review focuses on the molecular characteristics and development of rare malignant ovarian germ cell tumors (mOGCTs). We provide an overview of the genomic aberrations assessed by ploidy, cytogenetic banding, and comparative genomic hybridization. We summarize and discuss the transcriptome profiles of mRNA and microRNA (miRNA), and biomarkers (DNA methylation, gene mutation, individual protein expression) for each mOGCT histological subtype. Parallels between the origin of mOGCT and their male counterpart testicular GCT (TGCT) are discussed from the perspective of germ cell development, endocrinological influences, and pathogenesis, as is the GCT origin in patients with disorders of sex development. Integrated molecular profiles of the 3 main histological subtypes, dysgerminoma (DG), yolk sac tumor (YST), and immature teratoma (IT), are presented. DGs show genomic aberrations comparable to TGCT. In contrast, the genome profiles of YST and IT are different both from each other and from DG/TGCT. Differences between DG and YST are underlined by their miRNA/mRNA expression patterns, suggesting preferential involvement of the WNT/β-catenin and TGF-β/bone morphogenetic protein signaling pathways among YSTs. Characteristic protein expression patterns are observed in DG, YST and IT. We propose that mOGCT develop through different developmental pathways, including one that is likely shared with TGCT and involves insufficient sexual differentiation of the germ cell niche. The molecular features of the mOGCTs underline their similarity to pluripotent precursor cells (primordial germ cells, PGCs) and other stem cells. This similarity combined with the process of ovary development, explain why mOGCTs present so early in life, and with greater histological complexity, than most somatic solid tumors.

Male reproductive health after childhood, adolescent, and young adult cancers: a report from the Children's Oncology Group

The majority of children, adolescents, and young adults diagnosed with cancer will become long-term survivors. Although cancer therapy is associated with many adverse effects, one of the primary concerns of young male cancer survivors is reproductive health. Future fertility is often the focus of concern; however, it must be recognized that all aspects of male health, including pubertal development, testosterone production, and sexual function, can be impaired by cancer therapy. Although pretreatment strategies to preserve reproductive health have been beneficial to some male patients, many survivors remain at risk for long-term reproductive complications. Understanding risk factors and monitoring the reproductive health of young male survivors are important aspects of follow-up care. The Children's Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancer (COG-LTFU Guidelines) were created by the COG to provide recommendations for follow-up care of survivors at risk for long-term complications. The male health task force of the COG-LTFU Guidelines, composed of pediatric oncologists, endocrinologists, nurse practitioners, a urologist, and a radiation oncologist, is responsible for updating the COG-LTFU Guidelines every 2 years based on literature review and expert consensus. This review summarizes current task force recommendations for the assessment and management of male reproductive complications after treatment for childhood, adolescent, and young adult cancers. Issues related to male health that are being investigated, but currently not included in the COG-LTFU Guidelines, are also discussed. Ongoing investigation will inform future COG-LTFU Guideline recommendations for follow-up care to improve health and quality of life for male survivors.

Very late relapse of testicular tumour in combination with renal cancer and their retroperitoneoscopic removal

Late relapse of a testicular cancer is an uncommon occurrence. We report a case of late relapse of a testicular tumour combined with a renal cancer and their successful removal with retroperitoneoscopy. The 36-year-old patient underwent left orchiectomy, retroperitoneal lymph node dissection, and chemotherapy, because of mixed tumor including teratoma and embryonal carcinoma. 18 years after the successful primary therapy elevated serum alpha-fetoprotein level had been confirmed, then MRI and PET-CT scans demonstrated a 30 mm left renal mass and 22 mm retroperitoneal lymph node above the bifurcation of the left common iliac artery. We performed retroperitoneoscopic lymph node dissection and left renal tumour resection in the same session. The histology revealed embryonal carcinoma for the retroperitoneal lymph node and renal cell carcinoma for the left renal mass. We can conclude that late followup of patients with testicular tumour is important. Retroperitoneoscopy is feasible approach for the removal of retroperitoneal lymph node metastasis and resection of renal tumor.

Pure seminoma: a review and update

Pure seminoma is a rare pathology of the young adult, often discovered in the early stages. Its prognosis is generally excellent and many therapeutic options are available, especially in stage I tumors. High cure rates can be achieved in several ways: standard treatment with radiotherapy is challenged by surveillance and chemotherapy. Toxicity issues and the patients' preferences should be considered when management decisions are made. This paper describes firstly the management of primary seminoma and its nodal involvement and, secondly, the various therapeutic options according to stage.

Sequelae of treatment in long-term survivors of testis cancer

CONTEXT

Testicular cancer patients are often diagnosed at a young age, and because of the advances in the treatment of this disease, the vast majority have a normal life expectancy after therapy. Thus, recognition of the long-term sequelae of treatment (ie, surgery, radiation therapy, and chemotherapy) is particularly important in these patients.

OBJECTIVE

To review the adverse effects and the risk of secondary malignancy in long-term survivors of testicular cancer.

EVIDENCE ACQUISITION

We conducted a Medline search to identify original articles and reviews on the long-term effects of testicular cancer treatment. Although the search included articles from January 1948 to February 2011, the majority of the included articles were published in the last two decades.

EVIDENCE SYNTHESIS

All studies examining the long-term sequelae of treatment in testicular cancer are retrospective in nature, with most classified as cohort, case-control, and/or epidemiologic studies. Given that no standardized method of reporting long-term complications exists, evidence synthesis is limited.

CONCLUSIONS

Recent evidence suggests an increased risk of cardiovascular disease, neurotoxicity, and mild reductions in renal function in survivors of testicular cancer. Treatment of testicular malignancy can also negatively affect gonadal function and fertility and has been shown to result in an increased risk of solid malignancy and leukemia.

A prospective study of cognitive complaints in patients with testicular cancer

Self-reported memory and concentration problems (cognitive complaints) among testicular cancer patients treated with chemotherapy or radiotherapy during the 1990-ies were prospectively explored. The chemotherapy group had significantly higher prevalence of cognitive complaints compared to the radiotherapy group at 3-months follow-up, while at 12-months no significant group difference was found. Treatment modality (chemotherapy vs. radiotherapy) was not significantly associated with the presence of cognitive complaints at any time point after adjustment for relevant QoL variables.

INTRODUCTION

Cognitive complaints are frequent among patients with cancer. Oncologists and patients have become concerned that systemic chemotherapy may have cognitive side effects. After this concern became public there was a risk of expectation bias in studies of cognitive complaints. We prospectively explored cognitive complaints in patients with testicular cancer treated with chemotherapy or radiotherapy during the 1990s, before today's increased awareness of this possible side effect.

PATIENTS AND METHODS

The European Organisation for Research and Treatment of Cancer (EORTC) quality of life (QoL) questionnaire (QLQ-C30) and a testicular cancer module (TC module) were completed before treatment (baseline), at 3 months, and at 12 months by 276 chemotherapy and 71 radiotherapy patients enrolled in 3 EORTC studies. Cognitive complaints were based on the cognitive function (CF) items (concentration and memory) of the QLQ-C30. Other QLQ-C30 functions and symptoms represented adjustment variables.

RESULTS

The chemotherapy group (CHEMO) showed a significant increase in prevalence of cognitive complaints from baseline to 3 months. At 12 months these rates were back at baseline levels. The radiotherapy group (RAD) showed no significant change in the prevalence of cognitive complaints over time. Significant differences between the 2 treatment groups were observed only at the 3-month follow-up. In multivariate analyses, treatment modality did not show significant association with cognitive complaints at any time point, whereas current fatigue showed significant associations at all time points.

CONCLUSION

In patients with testicular cancer with no information or expectation bias, an increased rate of cognitive complaints was observed shortly after chemotherapy, with return to baseline levels at 12 months. Treatment modality (chemotherapy vs. radiotherapy) was not associated with cognitive complaints at any time point after adjustment for relevant QoL variables.

Self-reported cognitive problems in testicular cancer patients: relation to neuropsychological performance, fatigue, and psychological distress

OBJECTIVE

There is a concern about negative cognitive effects of systemic chemotherapy. We prospectively explored self-reported cognitive problems in testicular cancer patients (TCPs) treated with and without chemotherapy.

METHODS

One hundred and twenty-two TCPs were interviewed about concentration and memory problems shortly after orchidectomy but before any additional treatment (baseline), and then at a median of 1 year after end of treatment (follow-up). Symptoms of psychological distress, fatigue, and peripheral neurotoxicity were assessed by questionnaires, and patients also underwent neuropsychological testing. Self-reported cognitive problems were compared between three treatments groups: no chemotherapy, one cycle of chemotherapy, and multiple cycles of chemotherapy. Variables associated with an increase of self-reported cognitive problems from baseline to follow-up were explored.

RESULTS

Significantly larger proportions of TCPs in the two chemotherapy groups had an increase of self-reported cognitive problems from baseline to follow-up compared to the no-chemotherapy group. Increase of self-reported cognitive problems was significantly associated with psychological distress, fatigue, lower level of education, and Raynaud-like symptoms, but not with a decline in neuropsychological test performance.

CONCLUSION

In this explorative study of TCPs, an increase of self-reported cognitive problems from baseline to 1-year follow-up was associated with chemotherapy and with symptoms of fatigue and psychological distress at follow-up, while no significant association was found with a decline in neuropsychological test performance.

[What's new in the treatment of seminomas?]

Pure testicular seminoma is a rare disease with an excellent prognosis. Its management is controversial. In stage I disease, several treatment options are considered. Those are radiation therapy alone, chemotherapy alone or active surveillance, which is becoming increasingly popular. For more advanced stages, treatment is based on chemotherapy with or without radiation therapy. In this article, we review thoroughly the existing literature and recent recommendations the various treatment options, their advantages and disadvantages in different stages of the disease.

Male factor assessment in infertility

Male infertility assessment is more than a semen analysis. By interpreting a semen analysis, clinicians recognize its uses and limitations. Once understood, clinicians can then apply modern techniques of endocrine and radiologic evaluation to diagnosis of male reproductive dysfunction. It is important to identify patients with infertility not only to allow reproductive potential but also to identify a population susceptible to future disease states.

Testicular germ cell tumors: pathogenesis, diagnosis and treatment

Testicular germ cell tumors represent the most common solid malignancy of young men aged 15-40 years. Histopathologically, testicular germ cell tumors are divided into two major groups: pure seminoma and nonseminoma. The pathogenesis of testicular germ cell tumors remains unknown; however, cryptorchidism is the main risk factor, and molecular studies have shown strong evidence of an association between genetic alterations and testicular germ cell tumors. In cases of suspicion for testicular germ cell tumor, a surgical exploration with orchiectomy is obligatory. After completion of diagnostic procedures, levels of serum tumor markers and the clinical stage based on the International Union Against Cancer tumor-node-metastasis classification should be defined. Patients with early-stage testicular germ cell tumors are treated by individualized risk stratification within a multidisciplinary approach. The individual management (surveillance, chemotherapy or radiotherapy) has to be balanced according to clinical features and the risk of short-term and long-term toxic effects. Treatment for metastatic tumors is based on risk stratification according to International Germ Cell Cancer Collaborative Group classification and is performed with cisplatin-based chemotherapy and residual tumor resection in cases of residual tumor lesion. High-dose chemotherapy represents a curative option for patients with second or subsequent relapses.

A prospective study of neuropsychological functioning in testicular cancer patients

BACKGROUND

Whether systemic chemotherapy has a negative effect on cognitive function in patients, concern oncologists. In testicular cancer patients (TCPs) treated with cisplatin-based chemotherapy, only few cross-sectional studies have addressed this concern. We prospectively studied neuropsychological functioning in TCPs.

PATIENTS AND METHODS

In a consecutive sampling, 122 TCPs were examined at baseline (after orchidectomy, before any additional treatment) and then at follow-up at a median of 12 months after end of treatment. The examinations included a neuropsychological test battery, interview on background variables and questionnaires on mental distress, fatigue and neurotoxic symptoms. Changes in neuropsychological functioning from baseline to follow-up were compared between three treatments groups: no chemotherapy (N = 31), one cycle of chemotherapy (N = 38) and two or more cycles of chemotherapy (N = 53). Variables associated with a decline in neuropsychological test performance from baseline to follow-up were explored.

RESULTS

No statistically significant differences in proportions of TCPs with a decline in neuropsychological test performance were observed between the three treatment groups. Decline in neuropsychological test performance was not associated with demographic variables, distress, fatigue or with chemotherapy.

CONCLUSION

No negative effect of systemic chemotherapy on neuropsychological test performance in TCPs at 1-year follow-up was found in this study.
