Abstract
CONTEXT: - Testicular germ cell tumors with lymphovascular invasion (LVI) are staged pT2, and those with spermatic cord involvement are staged pT3.
OBJECTIVE: - To study the clinical significance of LVI within the spermatic cord without direct involvement of the cord soft tissues.
DESIGN: - A retrospective, multi-institutional review was performed on testicular GCTs with spermatic cord LVI in the absence of cord soft tissue invasion.
RESULTS: - Forty-four germ cell tumors had LVI in the spermatic cord without soft tissue invasion; 37 of 44 patients (84%) had nonseminomatous germ cell tumors (NSGCT), and 7 (16%) had pure seminomas. Patients with NSGCTs and spermatic cord LVI had worse clinical outcomes compared with patients with pure seminoma and spermatic cord LVI (P = .008). We then compared patients with NSGCTs and spermatic cord LVI (n = 37) to patients with NSGCTs and LVI limited to the testis (n = 32). A significantly greater percentage of patients with LVI in the spermatic cord presented with advanced clinical stage (76% versus 50%; P = .01). There was no statistically significant difference in disease recurrence/progression or death between patients with spermatic cord LVI and patients with LVI limited to the testis (P = .40; P = .50). There was no significant difference in the presence of embryonal dominant histology (P = .30) or rete testis invasion (P = .50) between the 2 groups. More hilar soft tissue invasion was seen in patients with LVI present in the spermatic cord (P = .004).
CONCLUSIONS: - In patients with NSGCTs, LVI in the spermatic cord, without soft tissue invasion, is associated with worse clinical stage at presentation compared with patients with LVI confined to the testis.
