Primary testicular lymphoma: Treatment patterns and survival of 1740 men from the National Cancer Database.
Abstract:
Background: The standard of care (SOC) for primary testicular lymphoma (PTL) is orchiectomy, chemotherapy (CHT) and radiation (RT) of the contralateral testis regardless of stage. PTL is rare and usually presents in elderly men; we hypothesized that men may not receive SOC and may have worse outcomes. To assess this, we queried the National Cancer Database (NCDB) which includes 70% of newly diagnosed US cancers, to analyze treatment patterns and survival of men with PTL in the rituximab era.
Methods: Using NCDB data (2006 to 2013), we searched for men diagnosed with extra nodal lymphoma (N = 109210), primary site testis (N = 1865). Patients were analyzed in 2 treatment groups: 1) CHT + RT (SOC group); and 2) CHT alone, RT alone and orchiectomy alone, grouped as no-SOC. Kaplan-Meier (KM) survival plots were used to investigate 5-year overall survival (OS). Log rank test was used to estimate survival differences between treatments.
Results: 1740 men with PTL underwent orchiectomy. Median age was 69. 794 (45.6%) were Stage 1, 217 (12.5%) were Stage 2, 88 (5.1%) were Stage 3, 274 (15.7%) were Stage 4. 367 men (21.1%) had no staging information available and were not included in the survival analysis. 619 (35.5%) received SOC, 692 (39.8%) had CHT alone, 54 (3.1%) had RT alone, and 375 (21.6%) received no further treatment. KM analysis by stage (Table 1) showed 5-year OS was significantly higher in the SOC group vs.non-SOC for Stage 1 (83.8% vs. 66.1%, p < 0.001), Stage 2 (78.2% vs. 58.7%, p = 0.003) and Stage 4 (64.3% vs. 54.5%, p = 0.001). Stage 3 patients receiving SOC had a non-significant trend toward survival advantage (74.1% vs 60.7%, p = 0.07).
Conclusions: This study represents the largest PTL cohort reported to date and is reflective of current treatments. These data show that most US PTL patients do not receive guideline-recommended SOC, and OS is significantly worse across stages for those that do not receive SOC, highlighting the need for improved management of PTL.
