Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute to this Special Issue titled “Immunotherapy and Targeted Treatment in Solid Tumors: Biomarkers and Novel Therapeutic Strategies” in Biomedicines. Immunotherapy and targeted therapies have revolutionized the treatment of solid tumors, significantly improving survival rates across multiple cancer types. However, not all patients respond equally to these therapies, and resistance mechanisms remain a major challenge. Understanding the molecular and immunological factors that influence treatment response is essential for advancing precision medicine approaches in oncology.

This Special Issue aims to explore innovative developments in immunotherapy and targeted therapies by focusing on predictive and prognostic biomarkers, combination strategies, and novel therapeutic approaches. The issue aligns with the scope of Biomedicines by emphasizing translational research that bridges molecular discoveries with clinical applications. We seek to provide a comprehensive perspective on optimizing cancer treatments through biomarker-driven strategies and emerging therapeutic innovations.

In this Special Issue, we welcome original research articles and comprehensive reviews. Topics of interest include (but are not limited to) the following research areas:

  • Biomarkers for predicting response and resistance to immunotherapy and targeted therapies;
  • Tumor microenvironment modulation and immune checkpoint inhibitors;
  • Advances in molecular profiling for precision oncology;
  • Novel combination strategies to overcome resistance and enhance treatment efficacy;
  • The role of the microbiome and host factors in immunotherapy response;
  • Translational research in cancer immunotherapy and targeted therapy;
  • Development of new agents and treatment paradigms in solid tumors;
  • Real-world data and clinical applications of precision oncology.

We look forward to receiving your contributions and collaborating on this exciting research topic.

Background and Purpose: Stratification based on specific image biomarkers applicable in clinical settings could help optimize treatment outcomes for recurrent non-small cell lung cancer patients. For this purpose, we aimed to determine the clinical impact of positive delta changes (any difference above zero > 0) between baseline [18F]FDG PET/CT metrics before the first treatment course and reirradiation. Material/Methods: Forty-seven patients who underwent thoracic reirradiation with curative intent at our institute between 2013 and 2021 met the inclusion criteria. All patients had histologically verified NSCLC, ECOG (Eastern Cooperative Oncology Group) ≤ 2, and underwent [18F]FDG PET/CT for initial staging and re-staging before primary radiotherapy and reirradiation, respectively. The time interval between radiation treatments was at least nine months. Quantitative metabolic volume and intensity parameters were measured before first irradiation and before reirradiation, and the difference above zero (>0; delta change) between them was statistically correlated to locoregional control (LRC), progression-free survival (PFS), and overall survival (OS). Results: Patients were followed for a median time of 33 months after reirradiation. The median OS was 21.8 months (95%-CI: 16.3–27.3), the median PFS was 12 months (95%-CI: 6.7–17.3), and the median LRC was 13 months (95%-CI: 9.0–17.0). Multivariate analysis revealed that the delta changes in SULpeak, SUVmax, and SULmax of the lymph nodes significantly impacted OS (SULpeak p = 0.017; SUVmax p = 0.006; SULmax p = 0.006), PFS (SULpeak p = 0.010; SUVmax p = 0.009; SULmax p = 0.009), and LRC (SULpeak p < 0.001; SUVmax p = 0.003; SULmax p = 0.003). Conclusions: Delta changes in SULpeak, SUVmax, and SULmax of the metastatic lymph nodes significantly impacted all clinical endpoints (OS, PFS and LRC) in recurrent NSCLC patients treated with reirradiation. Hence, these imaging biomarkers could be helpful with regard to patient selection in this challenging clinical situation. Full article
