The introduction of precision medicine and next-generation sequencing (NGS) has profoundly influenced the clinical management of PCa, particularly by enabling the assessment of genetic alterations that guide treatment decisions. Liquid biopsy using diverse sample types, including plasma, urine, and semen, offers non-invasive alternatives to tissue biopsies. This study sought to compare the performance of NGS-based mutation detection across various sample types in PCa patients.</p><p><strong>Methods: </strong>Thirty-seven PCa patients, diagnosed with intermediate to advanced stages (II-IV), were enrolled. All collected samples, including tissues (n = 34), plasma (n = 37), urine (n = 32), and seminal fluids (n = 9), underwent targeted NGS of 437 cancer-related genes.

Mutations in FOXA1, SPOP, and TP53 were commonly detected across most sample types with comparable prevalence. AR mutations were observed with similar frequencies in plasma and semen samples, but were absent in tissue and urine samples. The average MVAFs were at similar levels among tissue, plasma, urine, and semen, although urine sediment samples exhibited the lowest MVAFs. Advanced disease stages correlated with increased circulating tumor DNA (ctDNA) detection in both plasma and urine samples. No significant survival advantage associated with ctDNA negativity was observed, likely due to the small sample size.</p><p><strong>Conclusions: </strong>This study validates the utility of urine and plasma samples as non-invasive and sensitive liquid biopsy options for PCa, showing comparable ctDNA detection rates.

It commonly shows basaloid, eosinophilic, oncocytoid or rhabdoid morphology. However, it can exhibit yolk sac like differentiation in very rare cases, with associated SALL4, GPC-3 and CDX2 and AFP expression, which can lead to the misdiagnosis of primary nasopharyngeal yolk sac tumor (YST).</p><p><strong>Patient concerns: </strong>A 58-year-old male patient with right nasal cavity mass, he complained for persistent right-sided nasal congestion for 3 months, accompanied by decreased sense of smell and protrusion of the right eyeball.</p><p><strong>Diagnosis: </strong>Histology showed tumor cells with glandular, large cystic, and microcystic architectural arrangement. Immunohistochemically, the tumor cells expressed SALL-4 and GPC-3. The findings supported obvious yolk sac tumor like features.
