RESUMEN

Transformation from non-small cell lung cancer (NSCLC) to small cell lung cancer (SCLC) is rare and is associated with poor prognosis. However, the standard treatment protocols for patients with SCLC transformation remain unknown. Here, we report the case of a patient with advanced EGFR exon 19 deletion (19del) NSCLC who underwent SCLC transformation during targeted therapy. Biopsies and genetic testing were performed to adjust treatment regimens accordingly. The patient responded favorably to a combined treatment regimen comprising etoposide plus cisplatin chemotherapy and adebrelimab plus osimertinib. This case highlights the critical importance of acknowledging tumor heterogeneity in clinical decision-making and identifying potentially effective treatment options for patients with SCLC transformation. Additionally, we reviewed cases of the transformation of NSCLC to SCLC from 2017 to 2023.

RESUMEN

PURPOSE: This study aims to identify patient subgroups who benefit more from perioperative immunotherapy combined with chemotherapy (IO-CT) based on clinical and molecular characteristics in resectable non-small cell lung cancer (NSCLC). METHODS: Randomized controlled trials (RCTs) on perioperative IO-CT were searched. Beneficial differences of IO-CT regimens across different patient subgroups were assessed by pooling trial-specific ratios in event-free survival (EFS), overall survival (OS), pathological complete response (pCR), and major pathological response (MPR). RESULTS: Six studies (n = 3003) involving five IO-CT regimens were included. Compared to CT alone, all IO-CT regimens significantly improved EFS, OS, MPR, and pCR, but increased toxicity. Toripa-chemo showed the best EFS and nivo-chemo showed the best OS. Patients with PD-L1 ≥ 1% had more EFS benefits compared to those with PD-L1 < 1% (HR [hazard ratio]: 1.55, 95% CI 1.17-2.04). Squamous NSCLC patients had significantly more pCR and MPR benefits than non-squamous NSCLC patients (pCR: OR [odds ratio] 0.68, 95% CI 0.49-0.95; MPR: OR 0.61, 95% CI 0.45-0.82). Former smokers had significantly higher pCR benefits than non-smokers (OR: 2.18; 95% CI 1.21-3.92). Additionally, OS benefit was significantly higher in patients < 65 years compared to those ≥ 65 years (HR ratio: 0.59, 95% CI 0.36-0.95). For MPR, males benefited significantly more from IO-CT compared to females (OR: 1.69, 95% CI 1.18-2.42). CONCLUSION: Perioperative IO-CT is more effective but more toxic than CT alone in resectable NSCLC. Patients with PD-L1 ≥ 1%, squamous NSCLC, a history of smoking, age < 65 years and male gender may experience greater benefits from perioperative IO-CT.

RESUMEN

BACKGROUND: Stage IIIA-N2 non-small cell lung cancer (NSCLC) poses a significant clinical challenge, with low survival rates despite advances in therapy. The lack of a standardised treatment approach complicates patient management. This study utilises real-world data from Guy's Thoracic Cancer Database to analyse patient outcomes, identify key predictors of overall survival (OS) and disease-free survival (DFS), and address the limitations of randomised controlled trials. METHODS: This observational, single-centre, non-randomised study analysed 142 patients diagnosed with clinical and pathological T1/2 N2 NSCLC who received curative treatment from 2015 to 2021. Patients were categorised into three groups: Group A (30 patients) underwent surgery for clinical N2 disease, Group B (54 patients) had unsuspected N2 disease discovered during surgery, and Group C (58 patients) received radical chemoradiation or radiotherapy alone (CRT/RT) for clinical N2 disease. Data on demographics, treatment types, recurrence, and survival rates were analysed. RESULTS: The median OS for the cohort was 31 months, with 2-year and 5-year OS rates of 60% and 30%, respectively. Group A had a median OS of 32 months, Group B 36 months, and Group C 25 months. The median DFS was 18 months overall, with Group A at 16 months, Group B at 22 months, and Group C at 17 months. Significant predictors of OS included ECOG performance status, lymphovascular invasion, and histology. No significant differences in OS were found between treatment groups (p = 0.99). CONCLUSIONS: This study highlights the complexity and diversity of Stage IIIA-N2 NSCLC, with no single superior treatment strategy identified. The findings underscore the necessity for personalised treatment approaches and multidisciplinary decision-making. Future research should focus on integrating newer therapeutic modalities and conducting multi-centre trials to refine treatment strategies. Collaboration and ongoing data collection are crucial for improving personalised treatment plans and survival outcomes for Stage IIIA-N2 NSCLC patients.

RESUMEN

The objective of this study was to enhance the membrane permeability and anticancer effectiveness of (20S)-protopanaxadiol (PPD) by introducing triphenylphosphonium into the OH group at the C-3 site. This study shows that the anti-proliferation activity of CTPPPPD, with an IC50 value of 1.65 ± 0.10 µmol/L, was 33-times better than that of PPD (with an IC50 value of 54.56 ± 4.56 µmol/L) and superior to that of cisplatin (with an IC50 value of 1.82 ± 0.25 µmol/L) against A549 cells. Biological examinations suggested that CTPPPPD treatment reduced the growth rate of A549 cells, increased the permeability of cell membranes, and changed the structure of chromosomal DNA in a concentration-dependent manner. Annexin V/PI assay and flow cytometry were employed to detect the effect of CTPPPPD on the apoptosis of A549 cells. The results showed that CTPPPPD could induce the apoptosis of A549 cells, and the apoptosis rate of A549 cells treated with 0, 1.0, 2.0, and 4.0 µM of CTPPPPD for 24 h was 0%, 4.9%, 12.7%, and 31.0%, respectively. The integration of transcriptomics and metabolomics provided a systematic and detailed perspective on the induced antitumor mechanisms. A combined analysis of DEGs and DAMs suggested that they were primarily involved in the central carbon metabolism pathway in cancer, as well as the metabolism of aminoacyl-tRNA biosynthesis, alanine, aspartate, and glutamate. Central carbon metabolism in cancer-related genes, i.e., SLC16A3, FGFR3, LDHA, PGAM1, and SLC2A1, significantly reduced after treatment with CTPPPPD. In particular, the dominant mechanism responsible for total antitumor activity may be attributed to perturbations in the PI3K-AKT, MAPK, and P53 pathways. The findings derived from transcriptomics and metabolomics were empirically confirmed through q-PCR and molecular docking. Further analyses revealed that CTPPPPD could be a promising lead for the development of protopanaxadiol for non-small-cell lung cancer (NSCLC) drugs.

RESUMEN

BACKGROUND: Circular RNAs (circRNAs) belong to a family of covalently closed single-stranded RNAs that have been implicated in cancer progression. Previous studies have reported that hsa_circ_0087784 was abnormally expressed in breast cancer. However, the role of hsa_circ_0087784 in non-small cell lung cancer (NSCLC) is unknown. METHODS: Here, we used RT-qPCR and FISH to examine hsa_circ_0087784 expression in NSCLC cells and tissue samples. The dual-luciferase reporter assay was used to identify downstream targets of hsa_circ_0087784. Transwell migration, 5-ethynyl-2´-deoxyuridine, and CCK-8 assays were used to examine migration and proliferation. Tumorigenesis and metastasis assays were used to determine the role of hsa_circ_0087784 in NSCLC progression in a mouse tumor xenograft model in vivo. RESULTS: We found that hsa_circ_0087784 was expressed at significantly high levels in NSCLC tissue samples and cell lines. Downregulation of hsa_circ_0087784 suppressed NSCLC cellular proliferation, as well as migration. Our dual-luciferase reporter assay revealed that miR-576-5p and CDCA4 were downstream targets of hsa_circ_0087784. CDCA4 overexpression or miR-576-5p suppression reversed the effects of hsa_circ_0087784 silencing on NSCLC cell migration, and EMT-related protein expression levels. CONCLUSION: Our findings suggested that downregulation of hsa_circ_0087784 inhibited NSCLC metastasis and progression through the regulation of CDCA4 expression and miR-576-5psponging.

RESUMEN

The treatment of non-small cell lung cancer (NSCLC) has evolved tremendously in recent decades as innovations in medical therapies advanced concomitantly with minimally invasive surgical techniques. Despite early skepticism regarding its benefits, video-assisted thoracoscopic surgery (VATS) techniques for the surgical resection of early-stage NSCLC have now become the standard of care. After being the subject of many studies since its inception, VATS has been shown to cause less postoperative pain, have shorter recovery time, and have fewer overall complications when compared to conventional open approaches. Furthermore, some studies have shown it to have comparable oncological outcomes, though more higher evidence studies are needed. Newer technologies and improved surgical instruments, advancements in nodule localization techniques, and improved preoperative staging procedures have allowed for the development of newer, less invasive techniques such as uniportal VATS and parenchymal-sparing sublobar resections, which might further improve postoperative rates of complications in specific cases. These minimally invasive approaches have allowed surgeons to offer surgery to high-risk patients and those who would otherwise not tolerate conventional thoracotomy, though some relative contraindications still exist. This review aims to describe the evolution of VATS lobectomy, current techniques, its indications, contraindications, preoperative testing, benefits, and outcomes in patients with stage I and II NSCLC.

RESUMEN

The main bottleneck in training a robust tumor segmentation algorithm for non-small cell lung cancer (NSCLC) on H&E is generating sufficient ground truth annotations. Various approaches for generating tumor labels to train a tumor segmentation model was explored. A large dataset of low-cost low-accuracy panCK-based annotations was used to pre-train the model and determine the minimum required size of the expensive but highly accurate pathologist annotations dataset. PanCK pre-training was compared to foundation models and various architectures were explored for model backbone. Proper study design and sample procurement for training a generalizable model that captured variations in NSCLC H&E was studied. H&E imaging was performed on 112 samples (three centers, two scanner types, different staining and imaging protocols). Attention U-Net architecture was trained using the large panCK-based annotations dataset (68 samples, total area 10,326 [mm2]) followed by fine-tuning using a small pathologist annotations dataset (80 samples, total area 246 [mm2]). This approach resulted in mean intersection over union (mIoU) of 82% [77 87]. Using panCK pretraining provided better performance compared to foundation models and allowed for 70% reduction in pathologist annotations with no drop in performance. Study design ensured model generalizability over variations on H&E where performance was consistent across centers, scanners, and subtypes.

RESUMEN

Background: Programmed cell death protein 1 (PD-1) inhibitor therapy has become a routine treatment for advanced non-small cell lung cancer (NSCLC). However, only some NSCLC patients would benefit from anti-PD-1 therapy. We urgently need to identify biomarkers associated with clinical response to change treatment strategies promptly for patients who fail to benefit from anti-PD-1 treatment. This study was aimed to explore whether circulating CD4+ T cells and CD8+ T cells could be biomarkers for predicting anti-PD-1 efficacy. Methods: In this study, 118 NSCLC patients who received anti-PD-1 therapy were enrolled. The percentages of circulating CD4+ T cells and CD8+ T cells before and after anti-PD-1 treatment were determined by flow cytometry. The programmed cell death ligand 1 (PD-L1) expression of tumor tissues was detected by immunocytochemistry. The anti-PD-1 treatment efficacy was assessed by immune response evaluation criteria in solid tumors (iRECIST). Results: The percentage of CD4+ T cells and CD4+/CD8+ ratio in the peripheral blood (PB) was significantly elevated after anti-PD-1 treatment. In contrast, the percentage of CD8+ T cells in the PB was significantly decreased after anti-PD-1 treatment. Furthermore, we found that the percentages of CD4+ T cells and CD4+/CD8+ ratios considerably increased, and the percentages of CD8+ T cells significantly reduced in the effective group. On the contrary, the patients in the ineffective group showed no significant differences in the biomarkers. Multivariate logistic revealed that the percentage of CD4+ T cells at baseline was an independent predictor of anti-PD-1 treatment. The area under the curve (AUC) of the CD4+ T cells percentage was 0.7834 with a cut-off value of 28.53% (sensitivity =82.5%, specificity =66.23%). Conclusions: The percentage of CD4+ T cells at baseline could predict anti-PD-1 efficacy in NSCLC patients.

RESUMEN

Background: Patients with non-small cell lung cancer (NSCLC) carrying SMARCA4 mutations (SMARCA4-Mut) tend to have more advanced disease and a poor prognosis. However, due to the rarity of this mutation and the lack of related studies, the characteristics of SMARCA4-Mut NSCLC patients remains poorly determined. To clarify the clinical characteristics and prognostic factors of SMARCA4-Mut NSCLC, we initiated the present study to provide a clinical reference. Methods: We used data from two cohorts of NSCLC-SMARCA4-mutated samples: The Cancer Genome Atlas (TCGA) database and our center's clinical data. The TCGA database was used to obtain 481 NSCLC-SMARCA4-Mut samples for clinical characterization. The center collected data on 224 consecutive NSCLC patients treated between December 2020 to July 2022. Among them, 26 harbored SMARCA4 mutations, and 20 were eligible for inclusion in the study. Clinical, pathological, and molecular features, as well as prognostic role of SMARCA4 mutations were analyzed. Additionally, we analyzed the prognostic impact of Napsin A expression in SMARCA4-Mut patients. Results: The TCGA database included 480 patients with SMARCA4-Mut NSCLC, 311 males (64.8%) and 169 females (35.2%), with a median age of 67 years. Among the 20 SMARCA4-Mut patients in our center series, 12 (60%) were males and 8 (40%) females, with a median age of 63. The intergroup prognostic correlation analysis showed that SMARCA4-Mut patients had significantly worse prognosis than those the wild-type SMARCA4 (SMARCA4-WT) (P=0.04). Within the SMARCA4-Mut group, patients with Napsin A expression had longer overall survival (OS) (P=0.03) than those without expression. Median survival in the Napsin A-positive and negative groups was 32 and 15 months, respectively. According to time-dependent receiver operating curve analysis, patients with Napsin A expression had significantly longer first-line treatment progression-free survival (PFS1) [area under the curve (AUC) =0.748] and OS (AUC =0.586). No prognostic value of Napsin A was found in patients SMARCA4-WT patients. Conclusions: SMARCA4-Mut is an adverse prognostic feature in NSCLC patients. Napsin A expression in SMARCA4-Mut patients is associated with prolonged OS.

RESUMEN

Background: Patients with non-small cell lung cancer (NSCLC) have been shown to exhibit elevated levels of soluble programmed death-ligand 1 (sPD-L1) in the blood, associated with poor survival in NSCLC. The bronchoalveolar lavage fluid (BALF) composition reflects the tumor microenvironment of lung cancer. In this study, we investigated sPD-L1 levels in BALF and its role as a prognostic and predictive marker in patients with stage IV NSCLC. Methods: We prospectively obtained BALF from lung cancer patients who underwent bronchoscopy between January 2020 and September 2022 at Chungnam National University Hospital (CNUH). Finally, 94 NSCLC stage IV patients were included in this study. Soluble PD-L1 levels in BALF were measured using a human PD-L1 Quantikine ELISA kit. Results: The correlation between PD-L1 expression in tumor cells and sPD-L1 in BALF was weakly positive (rho =0.314, P=0.002). The median overall survival (OS) of the low sPD-L1 in BALF group was 16.47 months [95% confidence interval (CI): 11.15-21.79 months], which is significantly longer than 8.87 months (95% CI: 0.0-19.88 months, P=0.001) in the high sPD-L1 in BALF group. In 64 patients treated with or without immune checkpoint inhibitors (ICIs), sPD-L1 in BALF was significantly associated with progression-free survival (PFS) and OS. In the subgroup analysis of 31 patients treated with ICI, the objective response rate (ORR) in the low sPD-L1 BALF group was significantly higher than in high sPD-L1 in BALF group (ORR: 60.9% vs. 12.5%, P=0.02). Conclusions: Soluble PD-L1 in BALF is a potential prognostic indicator for patients with stage IV NSCLC and a predictive marker for ICI treatment response.

RESUMEN

Background: A previous network meta-analysis (NMA) compared the efficacy of anaplastic lymphoma kinase (ALK) inhibitors in ALK-positive non-small cell lung cancer (NSCLC). The phase III INSPIRE study of iruplinalkib was published recently. The present study aimed to add the results related to iruplinalkib to the NMA. Methods: A systematic literature search was performed in PubMed, Embase, Cochrane Library, Google, and Baidu. Randomized controlled trials (RCTs) reporting the independent review committee-assessed progression-free survival (PFS), objective response rate (ORR), or disease control rate (DCR) results of Asian patients with ALK inhibitor-naïve advanced ALK-positive NSCLC were eligible for inclusion in the NMA. Risk of bias was assessed using the Cochrane Risk of Bias 2 tool. Bayesian fixed-effect models were used for the direct and indirect pairwise comparisons. This study was registered with PROSPERO (CRD42024555299). Results: Eight studies, involving 1,477 Asian patients and seven treatments (crizotinib, alectinib, brigatinib, ensartinib, envonalkib, iruplinalkib, and lorlatinib), were included in the NMA. In terms of the overall risks of bias, all of the studies had "some concerns". All the next-generation ALK inhibitors were statistically superior to crizotinib in terms of PFS. Iruplinalkib had the best surface under the cumulative ranking curve (74.0%), followed by brigatinib (69.1%) and ensartinib (63.7%). Most of the pairwise comparisons did not reveal significant differences in the ORR and DCR. In terms of both the ORR and DCR, alectinib ranked first, followed by lorlatinib. Conclusions: Next-generation ALK inhibitors had better efficacy than crizotinib in the treatment of Asian patients with ALK inhibitor-naïve advanced ALK-positive NSCLC. Iruplinalkib may have more favorable PFS benefit than other ALK inhibitors for Asians.

RESUMEN

Background: Pembrolizumab 400 mg every six weeks (Q6W) and nivolumab 480 mg every four weeks (Q4W) are used since 2020 and the coronavirus disease 2019 (COVID-19) pandemic. This recommendation relied on pharmacokinetic and pharmacodynamic models. The objective of the IDEE (Immunothérapie Double dose Etendue: Experience bretonne) study is to determine the safety and efficacy of this treatment regimen in real life conditions. Methods: We conducted an observational, retrospective, multicentric study including 117 patients with advanced non-small cell lung cancer (NSCLC) who received pembrolizumab Q6W or nivolumab Q4W between March 2020 and March 2021. Results: The median age was 67 years, 68% were men with predominantly lung adenocarcinoma. The median time to double-dose regimen failure (TDDF) was 9.2 months. The survival rate at 12 months was 79%. TDDF was not influenced by sex, line of treatment, pathologic subtypes or anti-programmed cell death protein 1 (PD-1) antibody. There was no correlation between TDDF and duration of prior exposition to immunotherapy before switching. Sixty-eight patients experienced double-dose treatment failure, 28% because of toxicity including five definitive discontinuations. Five grade ≥3 immune-adverse events were reported included two cases of pneumonitis, all responding to corticosteroid therapy. Conclusions: Our multicentric cohort supports the feasibility of pembrolizumab Q6W and nivolumab Q4W for patients with advanced NSCLC. There is no warning signal regarding safety neither efficacy in our real-life data.

RESUMEN

Background: Sleeve lobectomy (SL) and extended SL (ESL), which aim to preserve pulmonary function and enhance the quality of life of patients while ensuring oncological outcomes, are valuable surgical options for the treatment of centrally located non-small cell lung cancer (NSCLC). This study aimed to compare perioperative adverse events and long-term survival between SL and ESL in NSCLC patients, providing a comprehensive review of surgical outcomes, complications, and survival to assess the roles of SL and ESL in thoracic oncology. Methods: This single-center retrospective study assessed the outcomes of NSCLC patients who underwent SL or ESL from June 2014 to January 2022. The patients were selected based on specific inclusion criteria, and statistical analyses were conducted to examine the postoperative outcomes, overall survival (OS), and disease-free survival (DFS) of the patients. Results: A total of 218 patients met the inclusion criteria. Among 218 patients, 33 underwent ESL and 185 underwent SL. Compared to SL, ESL was associated with longer operative times and higher R0 resection rates (93.9% vs. 78.8%, P=0.047). Despite the higher complexity of ESL compared to SL, there were no significant differences in the perioperative complications or mortality rates between the groups. Survival analysis was conducted on the propensity score matching (PSM) data, the results demonstrated superior OS and DFS in the ESL group compared to the SL group. Advanced age, more advanced nodal (N) status, and non-R0 resection were significant predictors of poorer prognosis. Conclusions: ESL is a feasible and effective alternative for treating centrally located NSCLC, with better R0 resection rates and comparable survival outcomes to SL, without increasing the risk of grade III-IV complications. Further studies with larger cohorts need to be conducted to validate these findings and refine the surgical techniques.

RESUMEN

Background: Tumor markers such as serum carcinoembryonic antigen (CEA) and cytokeratin fragment 19 (CYFRA 21-1) are utilized for assessing the effectiveness of chemotherapy in non-small cell lung cancer (NSCLC) patients. Yet, it remains uncertain whether these markers can reliably forecast responses to combined chemoimmunotherapy. Our study aimed to examine the significance and effectiveness of these markers in predicting responses among NSCLC patients undergoing combined chemoimmunotherapy. Methods: This two-part observational study involved patients with NSCLC who were treated with combined chemoimmunotherapy in Japanese hospitals. An initial retrospective study of these patients, with serum CEA and CYFRA 21-1 as prognostic factors for combined chemoimmunotherapy outcomes, served as a discovery cohort. Patients in a subsequent prospective study served as a validation cohort, where we assessed the prognostic accuracy of CEA and CYFRA 21-1 cut-off points determined by the discovery cohort. Results: In total, 121 patients treated with combined chemoimmunotherapy were included, with 44 and 77 patients in the discovery and validation cohorts, respectively. Serum CYFRA 21-1 levels >3.0 ng/mL were significantly associated with progression-free survival (PFS) in both the discovery and validation cohorts (P=0.01, P=0.04, respectively). PFS did not differ significantly by CEA levels (P=0.21). Conclusions: After combined chemoimmunotherapy treatment, serum CYFRA 21-1 stands out as a potentially valuable biomarker for predicting the prognosis of NSCLC.

RESUMEN

Background: Immune checkpoint inhibitors (ICIs) have become one of the standard treatments for non-small cell lung cancer (NSCLC) patients without driver mutations. However, a considerable proportion of patients suffer from severe immune side effects and fail to respond to ICIs. As effective biomarkers, programmed cell death ligand 1 (PD-L1) expression, microsatellite instability (MSI), the tumor mutation burden (TMB) and tumor-infiltrating lymphocytes (TILs) require invasive procedures that place heavy physical and psychological burdens on patients. This study aims to identify simple and effective markers to optimize patient selection through therapeutic decisions and outcome prediction. Methods: This retrospective study comprised 95 patients with metastatic NSCLC who were treated with ICIs either as the standard of care or in a clinical trial. The following data were extracted from the medical records. The baseline and dynamic neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were calculated in the present study. Responses were assessed by computed tomography (CT) imaging and classified according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 every 6-12 weeks during treatment. Results: In total, 95 patients were included in the present study. The median age of patients was 61 years, 83.2% (79/95) patients were male, 62.1% (59/95) were former or current smokers, 66.3% (63/95) had adenocarcinoma, 93.7% (89/95) had stage IV disease, and 87.4% were without molecular alterations. A higher overall response rate (ORR) and prolonged median progression-free survival (PFS) was observed in patients with a lower cycle 3 (C3) NLR [7.7 vs. 5.5 months, hazard ratio (HR): 1.70, 95% confidence interval (CI): 0.90-3.22; P=0.12] and derived NLR (dNLR) (8.2 vs. 5.6 months, HR: 1.67, 95% CI: 0.94-2.97; P=0.08). After two cycles of ICI treatment, patients who had an increased NLR, dNLR, and PLR had a lower ORR and an inferior median PFS than those with a decreased NLR (5.5 vs. 8.5 months, HR: 1.87, 95% CI: 1.09-3.21; P=0.02), dNLR (5.6 vs. 8.4 months, HR: 1.49, 95% CI: 0.87-2.57; P=0.15), and PLR (11.8 vs. 5.5 months, HR: 2.28, 95% CI: 1.32-3.94; P=0.003). Moreover, patients with both an increased NLR and PLR had a worse ORR and median PFS than those with either an increased NLR or PLR, or both an increased NLR and PLR (11.8 vs. 5.5 vs. 5.6 months, P=0.003). In addition, the dynamic changes in the PLR could serve as an independent predictive factor of PFS in NSCLC patients treated with ICIs. Conclusions: Elevated dynamic changes in the NLR and PLR were associated with lower response rates and shorter PFS in the patients with NSCLC treated with ICIs. Our results also highlight the role of dynamic changes in the PLR in identifying patients with NSCLC who could benefit from ICIs.

RESUMEN

Background: Definitive chemoradiotherapy (dCRT) is the cornerstone for locally advanced non-small cell lung cancer (LA-NSCLC). The study aimed to construct a multi-omics model integrating baseline clinical data, computed tomography (CT) images and genetic information to predict the prognosis of dCRT in LA-NSCLC patients. Methods: The study retrospectively enrolled 105 stage III LA-NSCLC patients who had undergone dCRT. The pre-treatment CT images were collected, and the primary tumor was delineated as a region of interest (ROI) on the image using 3D-Slicer, and the radiomics features were extracted. The least absolute shrinkage and selection operator (LASSO) was employed for dimensionality reduction and selection of features. Genomic information was obtained from the baseline tumor tissue samples. We then constructed a multi-omics model by combining baseline clinical data, radiomics and genomics features. The predictive performance of the model was evaluated by the area under the curve (AUC) of the receiver operating characteristic (ROC) and the concordance index (C-index). Results: The median follow-up time was 30.1 months, and the median progression-free survival (PFS) was 10.60 months. Four features were applied to construct the radiomics model. Multivariable analysis demonstrated the Rad-score, KEAP1 and MET mutations were independent prognostic factors for PFS. The C-index of radiomics model, genomics model and radiogenomics model all performed well in the training group (0.590 vs. 0.606 vs. 0.663) and the validation group (0.599 vs. 0.594 vs. 0.650). Conclusions: The radiomics model, genomics model and radiogenomics model can all predict the prognosis of dCRT for LA-NSCLC, and the radiogenomics model is superior to the single type model.
