Temporal Trends in the Incidence of Testicular Cancer in the United States over the Past Four Decades

Insurance remains a major source of disparity for patients with testicular cancer: call for advocacy

OBJECTIVE

To evaluate the effects of socioeconomic factors, including insurance status, on treatment and survival for patients with testicular cancer.

PATIENTS AND METHODS

We extracted a retrospective cohort from the National Cancer Database that included patients diagnosed with testicular cancer 2004-2020. Competing-risks and Cox regression multivariate models including demographic, pathological, and socioeconomic covariates were constructed to evaluate receipt of treatment and death, respectively.

RESULTS

A total of 95 955 patients with testicular cancer were identified. Compared with private insurance, Medicaid (sub-distribution hazard ratio [SHR] 0.70, P < 0.001), Medicare (SHR 0.73, P < 0.001), and uninsured (SHR 0.72, P < 0.001) patients were associated with decreased likelihood of receiving chemotherapy. Compared with private insurance, Medicaid (SHR 0.55, P < 0.001), Medicare (SHR 0.76, P-value <0.001), uninsured (SHR 0.63, P-value < 0.001), and other government insurance (SHR 0.71, P = 0.010) was associated with decreased likelihood of receiving radiation. Medicaid insurance status (reference private, HR 2.60, P < 0.001) conferred the second largest hazard of death, behind having Stage III disease (reference Stage 0). Compared with private insurance, Medicare (HR 2.20, P < 0.001), no insurance (HR 2.32, P < 0.001), and other government insurance (HR 1.53, P = 0.027) statuses had higher risk of death. Patients diagnosed in Medicaid-expansion states had lower all-cause mortality (11.4% vs 13.6%, P < 0.001).

CONCLUSIONS

Testicular cancer care relies on early diagnosis and treatment. It is critically important to have a healthcare system where individuals have access to insurance and are served equitably.

French AFU Cancer Committee Guidelines - Update 2024-2026: Testicular germ cell cancer

OBJECTIVE

To update the recommendations for the management of germ cell tumours of the testis.

MATERIALS AND METHODS

Comprehensive PubMed review from 2022 on the diagnosis, treatment and follow-up of testicular germ cell tumours (TGT), as well as safety of treatments. The level of evidence of the studies was assessed.

RESULTS

The initial assessment of a patient with a germ cell tumour of the testis is based on a clinical examination, biological evaluation (by measuring the serum markers AFP, total hCG, and LDH) and radiological evaluation (scrotal ultrasound and thoraco-abdomino-pelvic computed tomography [TAP]). Inguinal orchiectomy is the first therapeutic step, as it allows histological diagnosis and defines the local stage and risk factors for progression in stage I nonseminomatous germ cell tumours (NSGCTs). For patients with pure stage I seminoma, the risk of progression is between 15 and 20%, so surveillance is preferred in compliant patients; adjuvant chemotherapy with carboplatin AUC 7 is an option; and the indications for lumbo-aortic radiotherapy are limited. For patients with stage I NSGCT, various options exist, namely, surveillance or a risk-adapted strategy (surveillance or 1 cycle of bleomycin etoposide cisplatin [BEP] depending on the presence or absence of vascular emboli within the tumour). Retroperitoneal lymph node dissection for staging has a very limited role. Treatment of metastatic GCT consists of chemotherapy with BEP in the absence of contraindication to bleomycin, the number of cycles of which is defined according to the prognostic groups of the International Germ Cell Cancer Consortium Group (IGCCCG). Lumbo-aortic radiotherapy is still the standard treatment for stage IIA seminomatous germ cell tumours (SGCTs). At the end of chemotherapy, the size of any residual mass should be assessed via a TAP scan for SNGCTs, with retroperitoneal lymph node dissection recommended for any residual mass greater than 1cm, along with removal of all other metastatic sites. For SGCT, reassessment via 18FDG PET scans is necessary to determine the surgical indication for residual masses>3cm. Surgery remains rare in these situations.

CONCLUSION

Adherence to the recommendations for the management of GCT results in excellent specific survival rates of 99% for patients with stage I disease and over 85% for patients with metastatic disease.

Regional Differences in Stage III Nonseminoma Germ Cell Tumor Patients Across SEER Registries

PURPOSE

We investigated regional differences in patients with stage III nonseminoma germ cell tumor (NSGCT). Specifically, we investigated differences in baseline patient, tumor characteristics and treatment characteristics, as well as cancer-specific mortality (CSM) across different regions of the United States.

METHODS

Using the Surveillance, Epidemiology, and End Results (SEER) database (2004-2018), patient (age, race/ethnicity), tumor (International Germ Cell Cancer Collaborative Group [IGCCCG] prognostic groups) and treatment (systemic therapy and retroperitoneal lymph dissection [RPLND] status) characteristics were tabulated for stage III NSGCT patients, according to 12 SEER registries representing different geographic regions. Multinomial regression models and multivariable Cox regression models testing for cancer-specific mortality (CSM) were used.

RESULTS

In 3,174 stage III NSGCT patients, registry-specific patient counts ranged from 51 (1.5%) to 1630 (51.3%). Differences across registries existed for age (12%-31% for age 40+), race/ethnicity (5%-73% for others than non-Hispanic whites), IGCCCG prognostic groups (24%-43% vs. 14-24% vs. 3%-20%, in respectively poor vs. intermediate vs. good prognosis), systemic therapy (87%-96%) and RPLND status (12%-35%). After adjustment, clinically meaningful inter-registry differences remained for systemic therapy (84%-97%) and RPLND (11%-32%). Unadjusted 5-year CSM rates ranged from 7.1% to 23.3%. Finally in multivariable analyses addressing CSM, 2 registries exhibited more favorable outcomes than SEER registry of reference (SEER Registry 12): SEER Registry 4 (Hazard Ratio (HR): 0.36) and SEER Registry 9 (HR: 0.64; both P = .004).

CONCLUSION

We identified important regional differences in patient, tumor and treatment characteristics, as well as CSM which may be indicative of regional differences in quality of care or expertise in stage III NGSCT management.

Lymph Node Dissection in Testicular Cancer: The State of the Art and Future Perspectives

PURPOSE OF REVIEW

This narrative review provides a comprehensive overview of the evolving role of retroperitoneal lymph node dissection (RPLND) in the management of testicular cancer (TC). It explores the significance of RPLND as both a diagnostic and therapeutic tool, highlighting its contribution to accurate staging, its impact on oncological outcomes, and its influence on subsequent treatment decisions.

RECENT FINDINGS

RPLND serves as an essential diagnostic procedure, aiding in the precise assessment of lymph node involvement and guiding personalized treatment strategies. It has demonstrated therapeutic value, particularly in patients with specific risk factors and disease stages, contributing to improved oncological outcomes and survival rates. Recent studies have emphasized the importance of meticulous patient selection and nerve-sparing techniques to mitigate complications while optimizing outcomes. Additionally, modern imaging and surgical approaches have expanded the potential applications of RPLND. In the context of TC management, RPLND remains a valuable and evolving tool. Its dual role in staging and therapy underscores its relevance in contemporary urological practice. This review highlights the critical role of RPLND in enhancing patient care and shaping treatment strategies, emphasizing the need for further research to refine patient selection and surgical techniques.

Twenty Years' Experience in Retroperitoneal Lymph Node Dissection for Testicular Cancer in a Tertiary Referral Center

Background and Objectives: The aim of this article is to present a single-surgeon, open retroperitoneal lymph node dissection (RPLND) series for testicular cancer in a high-volume center. Materials and Methods: We reviewed data from patients who underwent RPLND performed by an experienced surgeon at our institution between 2000 and 2019. We evaluated surgical and perioperative outcomes, complications, Recurrence-Free Survival (RFS), Overall Survival (OS), and Cancer-Specific Survival (CSS). Results: RPLND was performed in primary and secondary settings in 21 (32%) and 44 (68%) patients, respectively. Median operative time was 180 min. Median hospital stay was 6 days. Complications occurred in 23 (35%) patients, with 9 (14%) events reported as Clavien grade ≥ 3. Patients in the primary RPLND group were significantly younger, more likely to have NSGCT, had higher clinical N0 and M0, and had higher nerve-sparing RPLND (all p ≤ 0.04) compared to those in the secondary RPLND group. In the median follow-up of 120 (56-180) months, 10 (15%) patients experienced recurrence. Finally, 20-year OS, CSS, and RFS were 89%, 92%, and 85%, respectively, with no significant difference in survival rates between primary vs. secondary RPLND subgroups (p = 0.64, p = 0.7, and p = 0.31, respectively). Conclusions: Open RPLND performed by an experienced high-volume surgeon achieves excellent oncological and functional outcomes supporting the centralization of these complex procedures.

Hyperandrogenism and Hyperestrogenism Secondary to Mixed Germ-Cell Testicular Tumor

Testicular cancer with androgen and estrogen secretion is classically associated with Leydig cell tumors. Rare case reports have described this finding in germ-cell tumors along with signs of androgen and estrogen excess including gynecomastia and infertility. We report the case of a 19-year-old male with a non-seminomatous testicular germ-cell tumor found to have hyperandrogenism, hyperestrogenism, and suppression of central sex hormones. Similar findings may be underreported in the literature, and males with suspected testicular malignancy should be appropriately screened for signs of androgen and/or estrogen excess so they can be offered appropriate monitoring and counseling.
