In the era of precision oncology, comprehensive molecular profiling is critical for guiding targeted and immunotherapy strategies. This study presents the analytical and clinical validation of a 1021-gene next-generation sequencing (NGS) panel, designed for use with both formalin-fixed paraffin-embedded (FFPE) tissue- and liquid-biopsy specimens. Analytical validation confirmed the assay’s high sensitivity and specificity across variant types—including SNVs (Single Nucleotide Variations), indels, CNVs (Copy Number Variations), and fusions—down to a 0.5% variant allele frequency. The assay also accurately identified microsatellite instability (MSI) and tumor mutational burden (TMB), essential biomarkers for immunotherapy. Clinical validation was performed on over 1300 solid tumor samples from diverse histologies, revealing actionable alterations in over 50% of cases. The panel detected on-label treatment biomarkers in 12.57% of patients, increasing to 20.15% when immunotherapy markers were included. Additionally, the assay demonstrated strong concordance with orthogonal methods and was effective in detecting variants in plasma-derived circulating tumor DNA in 70% of evaluable cases. These findings support the robust performance and broad clinical applicability of the 1021-gene panel for comprehensive genomic profiling in both tissue and liquid biopsies, offering a valuable tool for personalized cancer treatment.

Background and Clinical Significance: Rectal angiosarcoma is an exceptionally rare and aggressive malignancy, comprising less than 1% of soft tissue sarcomas. This case highlights the diagnostic and therapeutic challenges posed by this disease, and the lack of established guidelines emphasizing the importance of a multidisciplinary approach. Case Presentation: A 41-year-old male firefighter, with a history of heavy smoking, presented with lower abdominal pain, rectal bleeding, and urgency. Imaging and biopsy confirmed rectal angiosarcoma, stage IIIB. The patient underwent IMRT/VMAT radiation therapy followed by laparoscopic rectal amputation with colostomy. No sign of recurrence or metastatic disease was present on follow-up imaging. Conclusions: This case underlines the importance of a personalized treatment strategy and multidisciplinary collaboration in rare malignancies. Early diagnosis and cooperation across specialties are critical for achieving the best possible outcomes.

Background: The primary endpoint was to assess the nutritional status in patients diagnosed with prostate cancer (PCa) in Romania. The secondary endpoint was to analyze the impact of obesity on mortality and disease recurrence. Methods: In this retrospective cohort study, we analyzed the files of 354 patients diagnosed with PCa between August 2001 and May 2022 and referred to the Medical Oncology Department of Neolife Medical Center. A total of 257 patients fulfilled the inclusion criteria and were the subject of this study. Results: Excess weight was seen in 190 (73.9%) patients, with 119 (46.3%) being overweight and 71 (27.6%) having obesity. Subgroup analysis showed that at diagnosis, patients with obesity (PwO) were younger (p = 0.022), had lower PSA (p = 0.016), and had lower 10-year all-cause mortality rates (p = 0.04) than patients without obesity. Patients with metastases had lower weight (p = 0.001) and BMI (p = 0.033), higher PSA (p < 0.001), Gleason scores (p = 0.002), ISUP grade group (p < 0.001), and 10-year all-cause mortality rate (p < 0.001) than patients without metastases. Weight (AUROC = 0.637, 95% CI: 0.557–0.717, p = 0.001; cut-off = 77.5 kg, Se = 52.5%, Sp = 71.2%) and BMI (AUROC = 0.591, 95% CI: 0.507–0.676, p = 0.033; cut-off = 23.5 kg/m², Se = 25.4%, Sp = 91.9%) were independent predictors of the presence of metastases at diagnosis. In the androgen deprivation therapy (ADT) group, PwO had a shorter time to castration resistance than patients without obesity (Log Rank test: χ2 = 4.395, p = 0.036). Conclusions: Weight and BMI are accessible tools that could be useful in determining the presence of metastatic disease. PwO on ADT may develop castration resistant PCa faster than patients without obesity.
