Young adult Latino testicular cancer survivors: a pilot study of Goal-focused Emotion regulation Therapy (GET)

PURPOSE

Young adult Latino testicular cancer survivors experience adverse impacts after treatment. We developed Goal-focused Emotion regulation Therapy (GET) to improve distress symptoms, goal navigation skills, and emotion regulation. This open pilot trial extended GET to Latino young adult survivors of testicular cancer and assessed feasibility and tolerability as well as changes in anxiety and depressive symptoms. Secondary outcomes included goal navigation, emotion regulation, and components of hope-related goal processes (i.e., agency and pathway mapping). To assess the extent to which GET is culturally congruent or in need of adaptation, the influence of simpatía and acculturative stress were also examined.

METHODS

Thirty-five eligible young adult (age 18-39) survivors treated with chemotherapy were enrolled and assessed at baseline. Study acceptability, tolerability, and therapeutic alliance were examined. Preliminary efficacy was evaluated for changes in anxiety and depressive symptoms as well as psychological processes (goal navigation, agency, goal pathway skill, and emotion regulation) from baseline to immediate post- and 3-month post-intervention.

RESULTS

Among the 35 men assessed at baseline, 54% initiated intervention sessions. Among these, 94.7% completed all study procedures. Helpfulness ratings of intervention components and therapeutic alliance scores were strong. Repeated measures ANOVA revealed significant reductions in anxiety and depressive symptoms from pre- to post-intervention with sustained change at the 3-month follow-up. Favorable patterns of change were also observed in GET-related psychological processes. Simpatía was associated with less depressive symptoms at post-intervention, but not change in anxiety. Acculturative stress was associated with increased anxiety and depressive symptoms over time.

CONCLUSION

GET is a feasible and acceptable intervention for reducing adverse outcomes after testicular cancer for young adult Latino men. Results should be considered preliminary but suggest meaningful changes in emotional and psychological outcomes.

Testicular seminoma presenting as a large conglomerate mass in abdomen

Testicular seminoma commonly occurs in young men aged between 15 and 45 years old. Those with testicular cancer may present with a lump or swelling in the testicle. If treated and managed early, patients can expect a greater than 95% success rate. However, advanced stages of testicular seminoma can lead to eventual metastasis. We present a 45-year-old male patient with a prior history of testicular seminoma who was admitted to the emergency department with abdominal distension and acute abdominal pain. The CT identified a rather sizable abdominal mass and the biopsy confirmed metastatic testicular seminoma. Lymphoma was considered as the other differential diagnosis. Abdominal metastasis is rare in patients with testicular seminoma and usually leads to a poor survival outcome. Our patient did not attend follow-up appointments postorchidectomy, likely resulting in abdominal metastasis of testicular seminoma. This demonstrates the importance of ongoing surveillance of seminoma patients, and the challenges associated with differentiating large abdominal conglomerate mass in the CT scan. This patient is currently on active chemotherapy with bleomycin, cisplatin, and etoposide.

[Bilateral synchronous anaplastic variant spermatocytic tumor: Report of a rare neoplasm]

Spermatocytic tumor is a very rare germ cell testicular neoplasm that accounts for less than 1% of testicular cancers. It generally affects older men with a mean age of 53.6 years (range 19-92 years). Spermatocytic tumor is classified within the group of germ cell tumors not related to germ cell neoplasia in situ. It presents clinicopathological characteristics different from classic seminoma and is not considered a variant of the latter. Due to a morphologic overlap with classical seminoma, it was called "sperm cell seminoma" in the past. The anaplastic variant of spermatocytic tumor is exceptional, few cases have been described in the literature, it presents an earlier onset compared to spermatocytic tumor and a benign behavior despite showing histological patterns similar to classic seminoma. We present the second case of bilateral synchronous anaplastic spermatocytic tumor, in a young patient treated with orchiectomy and chemotherapy.

Guideline of guidelines: follow-up after orchidectomy for clinical stage 1 testicular cancer

Several medical organisations have developed evidence-based guidelines for the diagnosis, management, and follow-up of testicular cancer. This article aimed to review, compare, and summarise the most updated international guidelines and surveillance protocols for clinical stage 1 (CS1) testicular cancer. We reviewed a total of 46 articles on proposed follow-up strategies for testicular cancer, and six clinical practice guidelines including four guidelines published by urological scientific associations and two guidelines published by medical oncology associations. Most of these guidelines have been developed by panels of experts with different backgrounds in clinical training, and geographic practise patterns, which explains the considerable variability between published schedules, and recommended follow-up intensity. We present you with a comprehensive review of the most important clinical practice guidelines and propose unifying recommendations based on the most up to date evidence to help standardise follow-up schedules based on patterns and risk of disease relapse.

Patterns of Relapse in Australian Patients With Clinical Stage 1 Testicular Cancer: Utility of the Australian and New Zealand Urogenital and Prostate Cancer Trials Group Surveillance Recommendations

PURPOSE

International guidelines advocate for active surveillance as the preferred treatment strategy for patients with stage 1 testicular cancer after orchidectomy although a personalized discussion is required.

MATERIALS AND METHODS

We conducted an analysis of individuals registered in iTestis, Australia's testicular cancer registry, to describe the patterns of relapse and outcomes of patients treated in Australia where the Australian and New Zealand Urogenital and Prostate Cancer Trials Group Surveillance Recommendations are widely adopted.

RESULTS

A total of 650 individuals diagnosed between 2000 and 2020 were included, 63% (411 of 650) seminoma and 37% (239 of 650) nonseminoma. The median age was 34 years (range 14-74). 26% (106 of 411) with seminoma and 15% (36 of 239) nonseminoma received adjuvant chemotherapy. After a median follow-up of 43 months (range 0-267) postorchidectomy, relapse occurred in 10% (43 of 411) of seminoma and 18% (43 of 239) of nonseminoma. The two-year relapse-free survival was 92% (95% CI, 89 to 95) and 82% (95% CI, 78 to 87) in seminoma and nonseminoma, respectively. All relapses (86 of 86) were detected at a routine surveillance visit; 98% (85 of 86) were asymptomatic and detected solely through imaging (62 of 86, 72%), tumor markers (6 of 86, 7%), or a combination (17 of 86, 20%). The most common relapse site was isolated retroperitoneal lymphadenopathy (53 of 86, 62%). No nonpulmonary visceral metastases occurred. At relapse, 98% (84 of 86) had International Germ Cell Cancer Collaborative Group (IGCCCG) good prognosis; 2 of 86 intermediate prognosis (both nonseminoma). No deaths occurred.

CONCLUSION

In our cohort of stage 1 testicular cancer, where national surveillance recommendations have been widely adopted, recurrences were detected at routine surveillance visits and, almost exclusively, asymptomatic with IGCCCG good-prognosis disease. This provides reassurance that active surveillance is safe.

The Importance of Repeat Imaging Prior to Treatment Decision-making in Testicular Cancer: Commentary From the Inaugural Global Society of Rare Genitourinary Tumors Summit

Testicular cancer is a rare cancer that often affects young and otherwise healthy patients. Imaging plays a critical role in the staging and surveillance of patients with testicular cancer. Indeterminate findings on staging or surveillance imaging, can lead to challenging management decisions for clinicians and patients. In this article, we review the importance of short-interval, repeat imaging for several scenarios faced by patients with testicular cancer and their clinicians. The challenging scenarios and recommendations provided in this article summarize the discussion from the inaugural Global Society of Rare Genitourinary Tumors (GSRGT) Summit held on December 11-12, 2020.

Imaging Modality and Frequency in Surveillance of Stage I Seminoma Testicular Cancer: Results From a Randomized, Phase III, Noninferiority Trial (TRISST)

PURPOSE

Survival in stage I seminoma is almost 100%. Computed tomography (CT) surveillance is an international standard of care, avoiding adjuvant therapy. In this young population, minimizing irradiation is vital. The Trial of Imaging and Surveillance in Seminoma Testis (TRISST) assessed whether magnetic resonance images (MRIs) or a reduced scan schedule could be used without an unacceptable increase in advanced relapses.

METHODS

A phase III, noninferiority, factorial trial. Eligible participants had undergone orchiectomy for stage I seminoma with no adjuvant therapy planned. Random assignment was to seven CTs (6, 12, 18, 24, 36, 48, and 60 months); seven MRIs (same schedule); three CTs (6, 18, and 36 months); or three MRIs. The primary outcome was 6-year incidence of Royal Marsden Hospital stage ≥ IIC relapse (> 5 cm), aiming to exclude increases ≥ 5.7% (from 5.7% to 11.4%) with MRI (v CT) or three scans (v 7); target N = 660, all contributing to both comparisons. Secondary outcomes include relapse ≥ 3 cm, disease-free survival, and overall survival. Intention-to-treat and per-protocol analyses were performed.

RESULTS

Six hundred sixty-nine patients enrolled (35 UK centers, 2008-2014); mean tumor size was 2.9 cm, and 358 (54%) were low risk (< 4 cm, no rete testis invasion). With a median follow-up of 72 months, 82 (12%) relapsed. Stage ≥ IIC relapse was rare (10 events). Although statistically noninferior, more events occurred with three scans (nine, 2.8%) versus seven scans (one, 0.3%): 2.5% absolute increase, 90% CI (1.0 to 4.1). Only 4/9 could have potentially been detected earlier with seven scans. Noninferiority of MRI versus CT was also shown; fewer events occurred with MRI (two [0.6%] v eight [2.6%]), 1.9% decrease (-3.5 to -0.3). Per-protocol analyses confirmed noninferiority. Five-year survival was 99%, with no tumor-related deaths.

CONCLUSION

Surveillance is a safe management approach-advanced relapse is rare, salvage treatment successful, and outcomes excellent, regardless of imaging frequency or modality. MRI can be recommended to reduce irradiation; and no adverse impact on long-term outcomes was seen with a reduced schedule.

Spermatocytic tumor: A rare case report

BACKGROUND

Spermatocytic tumor is a rare, malignant neoplasm of the testes. Since the prognosis for this tumor type is favorable, accurate diagnosis and differentiation from other malignant testicular neoplasms (classic seminoma and lymphoma) are crucial. To add to the existing literature on the diagnosis of spermatocytic tumor, herein we report the detailed clinical and histopathologic findings for a case that we encountered.

CASE SUMMARY

A 60-year-old Chinese man presented with a solid mass in the right scrotum. The mass was surgically removed and spermatocytic tumor was diagnosed. On microscopy, the tumor cells displayed an unusual arrangement in lobules, presenting a pseudo-glandular appearance. To summarize and compare the diagnostic features of this tumor and those of the differential diagnoses, we report our case findings and those mentioned in the literature for various testicular tumors. Although imaging methods can detect masses early in development, their diagnostic capabilities are limited. Biopsy, histopathology, and immunohistochemistry are necessary for confirmatory diagnosis.

CONCLUSION

It is important to identify and review the key diagnostic features of spermatocytic tumor.

A Randomized Controlled Trial of Goal-Focused Emotion-Regulation Therapy for Young Adult Survivors of Testicular Cancer: Effects on Salivary and Inflammatory Stress Markers

Despite the substantial adverse psychological impact of testicular cancer, few interventions have sought to improve psychosocial functioning and stress-related biomarkers in young adult survivors. Goal-focused Emotion-regulation Therapy (GET) is designed to improve distress symptoms, emotion regulation, and goal navigation skills, which would be expected to improve regulation of stress-sensitive biomarkers. The aim was to examine the effects of GET versus an active control intervention on salivary stress and circulating inflammatory markers in young adult survivors of testicular cancer. Young adult men with testicular cancer (N = 44) who had undergone chemotherapy within the last 2 years were randomized to GET or individual supportive therapy (ISP) delivered over 8 weeks. Saliva samples were collected for 2 consecutive days at baseline and post-intervention (awakening, 8 hr later, bedtime) to measure diurnal rhythm. Circulating plasma levels of CRP, IL-6, IL-1ra, TNFαRII, and VEGF were measured at baseline and post-intervention. Regression modeling demonstrated a significant group effect on daily output of salivary cortisol (area under the curve) (β = −57, p < .05), with cortisol output decreasing from baseline to post-intervention for those receiving GET (Cohen’s d = 0.45). There were no significant intervention effects in salivary alpha-amylase. Plasma levels of IL-1ra were significantly lower post-intervention in GET compared to ISP; no other significant plasma effects were observed. GET, an intervention designed to promote goal-related and emotion-focused self-regulation, has potential to mitigate stress-related processes and inflammation in this young adult survivor group. More research is needed to determine efficacy.

Magnetic resonance versus computed tomography for the detection of retroperitoneal lymph node metastasis due to testicular cancer: A systematic literature review

INTRODUCTION

It is essential to see if MRI can be used as an alternative to CT for the detection of retroperitoneal lymphadenopathy in patients with testicular neoplasms. By doing so, the amount of radiation received by these young patients might be reduced.

MATERIAL AND METHODS

A systematic literature review was carried out in 5 databases between January 1984 until December 2020. The articles included were randomized and non-randomized clinical trials, cross-sectional studies, cohort, case and control, and retrospective studies that compare the accuracy of MRI against CT to detect retroperitoneal lymph nodes in patients with testicular neoplasms.

RESULTS

The search string initially retrieved 222 non duplicated papers from which a total of 3 studies of diagnostic accuracy were included for analysis. These articles evaluated a total of 127 patients with testicular neoplasm; the sample size per study ranged from 25 to 52 patients, with a mean age between 29-34 years. MRI presented a sensitivity ranging from 98-80% and specificity of 100 % when read by an experienced radiologist. However, when it was read by a radiologist with 1 year of experience, the sensitivity dropped to 78 % and specificity to 91%.

CONCLUSION

This systematic literature review shows a knowledge gap since not much has been published regarding this topic; therefore, randomized clinical trials are mandatory. Research on when to use MRI over CT is necessary to reduce radiation exposure. The authors strongly suggest that readers start researching on this subject.

Two cycles of adjuvant carboplatin for clinical stage 1 testicular seminoma in New Zealand centres: A retrospective analysis of efficacy and long-term events

Background

Adjuvant carboplatin reduces relapse risk in clinical stage 1 (CS1) seminoma, though there is a paucity of long‐term safety data.

Aim

Our objective was to report long‐term outcomes of two cycles of adjuvant carboplatin dosed at area under the time–concentration curve (AUC) of 7.

Methods and results

We performed a retrospective analysis on treatment and outcomes of patients with CS1 seminoma who received adjuvant carboplatin from 2000 to 2016 at our centres in the Midland Region, New Zealand. Of 159 patients, median age 39 years, 153 received two cycles of carboplatin: 147 dosed at AUC7 and 6 at AUC6. Six patients had one cycle of carboplatin AUC7. One patient relapsed at 22 months and died of bleomycin pneumonitis 2 months after achieving a complete response with BEP chemotherapy. Neither RTI (present in 21.3%) nor tumor size >4 cm (in 43.3%) was predictive of relapse. Median follow‐up was 106 months. At 15 years, outcomes were: relapse‐free survival 99.4%, overall survival 91.4%, disease‐specific survival 100%, subsequent malignant neoplasm rate 7.6%, and second testicular germ cell tumor rate 3.85%. One patient had persistent grade 1 thrombocytopenia at 46 months.

Conclusions

These data add to the body of evidence that two cycles of carboplatin AUC7 is safe and effective adjuvant treatment for CS1 seminoma.

Follow-up of percutaneous microwave (MW) ablation of hepatic lesion: predictive value of CT at 24-h compared with CT at 1 month

To retrospectively assess the predictive value of the CT performed at 24 h, compared with the CT performed at 1 month, in the evaluation of the technical success of microwave (MW) ablation of hepatic lesions. In a single center, 50 patients with HCC underwent percutaneous MW ablation between November 2016 and March 2019. Each patient underwent a contrast-enhanced CT exam at 24 h and at 1 month after the procedure. For each patient, was assessed the presence or absence of residual disease, the appearance of a new lesion, complications, and the involvement of the hepatic capsule, both at 24-h and at 1 month. Overall correlation between residual disease, appearance of a new nodule and complications was also assessed. A total of 50 hepatic lesions were treated with US-guided MW ablation. Patients' mean age was 70.9 years (range 28-87 years). Mean nodule diameter was 17.6 mm (range 7-35 mm). Contingency tables and the χ² test showed a strong association when looking at capsule involvement (accuracy: 100%), residual disease (accuracy: 90%; p-value 0.003), and the appearance of a new HCC nodule (accuracy: 88%; p-value 0.007); regarding complications, the accuracy was 78% (p-value 0.014). Optimal correlation was reached in 62% of cases, moderate correlation in 26%, minimum correlation in 10% of cases; no cases of zero correlation were recorded. CT at 24 h and 1 month showed comparable efficacy in evaluating residual disease after MW thermal ablation of liver lesions. However, further studies are needed to assess which factors may cause false-negative results at the 24-h CT.

Contemporary management of early stage testicular seminoma

Therapy for early stage testicular seminoma has changed radically over the past several decades. Given high cure rates and clinical trials supporting less active therapy in most cases, close observation after radical orchiectomy is now considered standard of care for clinical stage (CS) IA/IB seminoma, with either radiation therapy (RT) or chemotherapy salvage options possible. For CS IIA/IIB seminoma characterized by non-bulky retroperitoneal lymph node involvement (≤5 cm in greatest dimension), RT or combination chemotherapy are the standard of care. Given high comparable survival rates, preventing treatment-related toxicity and second malignancy, and limiting quality of life deficits associated with intense treatment has gained much greater importance. Clinical trials are currently testing the feasibility of retroperitoneal lymph node dissection (RPLND) for low volume CS IIA/IIB metastatic testicular seminoma to this end. Likewise, one cycle of chemotherapy is being evaluated as an adjuvant approach to reduce recurrence rates in CS I disease with unfavorable risk factors. Moreover, recent genomic and molecular studies have recently identified novel signatures and a potential biomarker for testicular seminoma. In this review, we first summarize the evolution of early stage seminoma management and discuss the effectiveness and drawbacks of contemporary treatment strategies. We further outline future perspectives and potential challenges in management of early stage testicular seminoma.
