Early Stage Nsclc

Lung cancer is worldwide the most common malignancy. Standard of care treatments for early-stage non-small-cell lung cancer (NSCLC) include surgery and adjuvant chemotherapy. However, these patients continue to have poor prognosis due to systemic or local relapse. Immunotherapy has been considered as a novel approach to improve survival in patients with early-stage NSCLC. Since immune checkpoint inhibitors have transformed the treatment of advanced NSCLC, there is a growing interest in the role of immunotherapy in early-stage NSCLC. In this review, we summarize reported and ongoing clinical trials of immunotherapy in both neoadjuvant and adjuvant settings. We also highlight unaddressed issues in this field of research, such as the predictive markers, the optimal combination therapy, and the need for adjuvant immunotherapy. More studies are needed to optimize the treatment regimen of immunotherapy in patients with early-stage NSCLC.

Surgical Methods

An active introduction of screening programs potentially leads to a significant increase in the proportion of patients with early forms of non-small cell lung cancer. Surgical treatment, which is the standard of care for localized forms, due to functional limitations can be performed only in 65-70% of patients. The solution to this problem can be found in the improvement of the results of radiotherapy by using modern equipment, the planning systems, improved fractionation schemes and introduction of methods for summing radiation doses. Stereotactic radiotherapy allows high-precision delivery of high radiation dose to tumor with a minimal damage to surrounding healthy tissues. In this literature review based on the analysis of a large number of publications we show that it is not yet possible to make valid conclusions about the effectiveness and safety of stereotactic radiation therapy as an alternative to the surgical methods. It is necessary to plan and conduct randomized trials without further delay taking into account the expected high relevance of the method.

Metabolic alterations in malignant cells play a vital role in tumor initiation, proliferation, and metastasis. Biofluids from patients with non–small cell lung cancer (NSCLC) harbor metabolic biomarkers with potential clinical applications. In this study, we assessed the changes in the metabolic profile of patients with early-stage NSCLC using mass spectrometry and nuclear magnetic resonance spectroscopy before and after surgical resection. A single cohort of 35 patients provided a total of 29 and 32 pairs of urine and serum samples, respectively, pre-and post-surgery. We identified a profile of 48 metabolites that were significantly different pre- and post-surgery: 17 in urine and 31 in serum. A higher proportion of metabolites were upregulated than downregulated post-surgery (p < 0.01); however, the median fold change (FC) was higher for downregulated than upregulated metabolites (p < 0.05). Purines/pyrimidines and proteins had a larger dysregulation than other classes of metabolites (p < 0.05 for each class). Several of the dysregulated metabolites have been previously associated with cancer, including leucyl proline, asymmetric dimethylarginine, isopentenyladenine, fumaric acid (all downregulated post-surgery), as well as N6-methyladenosine and several deoxycholic acid moieties, which were upregulated post-surgery. This study establishes metabolomic analysis of biofluids as a path to non-invasive diagnostics, screening, and monitoring in NSCLC.
