There is a lack of useful diagnostic tools to identify EGFR mutated NSCLC patients with long-term survival. This study develops a prognostic model using real world data to assist clinicians to predict survival beyond 24 months. EGFR mutated stage IIIB and IV NSCLC patients diagnosed between January 2009 and December 2017 included in the Spanish Lung Cancer Group (SLCG) thoracic tumor registry. Long-term survival was defined as being alive 24 months after diagnosis. A multivariable prognostic model was carried out using binary logistic regression and internal validation through bootstrapping. A nomogram was developed to facilitate the interpretation and applicability of the model. 505 of the 961 EGFR mutated patients identified in the registry were included, with a median survival of 27.73 months. Factors associated with overall survival longer than 24 months were: being a woman (OR 1.78); absence of the exon 20 insertion mutation (OR 2.77); functional status (ECOG 0–1) (OR 4.92); absence of central nervous system metastases (OR 2.22), absence of liver metastases (OR 1.90) or adrenal involvement (OR 2.35) and low number of metastatic sites (OR 1.22). The model had a good internal validation with a calibration slope equal to 0.781 and discrimination (optimism corrected C-index 0.680). Survival greater than 24 months can be predicted from six pre-treatment clinicopathological variables. The model has a good discrimination ability. We hypothesized that this model could help the selection of the best treatment sequence in EGFR mutation NSCLC patients.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of chemotherapy. CIPN can lead to a dose reduction and/or the interruption of chemotherapy, limiting its effectiveness, while chronic CIPN decreases patients’ quality of life. Improvements in cancer treatment and patients’ survival have increased the number of patients living with CIPN. The only evidence-based treatment for CIPN-related pain, duloxetine, provides only modest clinical benefit, and there is no effective clinical management option for numbness and tingling. Several experimental studies and clinical reports suggest that adjuvant ozone treatment may be beneficial in managing CIPN. Methods: This narrative review aims to provide an overview of current knowledge regarding CIPN and ozone therapy. Specifically, it summarizes experimental studies (18) and clinical reports (27) published between 1995 and 2025 that offer preliminary evidence supporting the potential role of ozone treatment in managing CIPN, highlighting the need for ongoing randomized clinical trials to establish its efficacy. Additionally, this review highlights existing gaps in the literature and proposes directions for future research. Results: The hypothesized mechanisms of action and experimental findings suggest that ozone therapy may be a valuable intervention for CIPN, a concept supported by preliminary clinical observations. Conclusions: Clinically relevant approaches for established CIPN are currently unavailable. While preliminary data suggest a potential role of ozone therapy, clinical evidence remains limited. Further high-quality randomized controlled trials are needed to confirm its efficacy and safety in this context; several trials are currently ongoing.

In the context of advanced BRAF-mutant melanoma, the treatment landscape has undergone a paradigm shift due to the impact of immune checkpoint inhibitors and BRAF/MEK inhibitors. This article presents three clinically illustrative melanoma cases that served as focal points for in-depth discussions during 12 expert meetings held across Spain. These include a treatment-naïve metastatic melanoma patient, a patient experiencing a recurrence while on anti-PD-1 adjuvant therapy, and a third patient whose melanoma relapsed ≥6 months after the end of adjuvant therapy. The discussions revolved around optimal treatment sequencing, emphasizing the challenges and alternatives discussed in each scenario. The common view aligned towards a nuanced approach that involves navigating the complexities of treatment choices. The conclusions underscore the need for personalized therapeutic strategies and highlight the ongoing challenge of refining real-life evidence-based algorithms for the management of metastatic BRAF-mutant melanoma.
