Article Abstract
Case 1: 63-year-old woman received abdominoperineal resection with lateral lymph node dissection for rectal cancer in 2008. After adjuvant chemotherapy, she suffered from lung metastasis and received partial pneumonectomy in 2012. However, chemotherapy was performed again for lung metastasis and mediastinal lymph nodes in 2013. Radiofrequency ablation (RFA)was performed to lung metastasis in 2016 due to ineffectiveness of chemotherapy. Case 2: 81-year-old man received Hartmann's procedure for rectal cancer with lung and liver metastasis in 2012. After 6 months of chemotherapy, liver partial resection and pulmonary partial resection were performed. In spite of additional chemotherapy, He received partial pneumonectomy in 2013. In 2014, he restart chemotherapy due to lung metastasis. In 2016, he received RFA for lung metastasis because of ineffectiveness of chemotherapy. After that, he received g-knife for brain metastasis. He is going to receive RFA for another lung metastasis.

Purpose: Lung cancer is currently the most common malignant tumor worldwide and one of the leading causes of cancer-related deaths, posing a serious threat to human health. MicroRNAs (miRNAs) are a class of endogenous non-coding small RNA molecules that regulate gene expression and are involved in various biological processes associated with lung cancer. Understanding the mechanisms of lung carcinogenesis and detecting disease biomarkers may enable early diagnosis of lung cancer.

Aberrant DNA methylation has been described in nearly all human cancers, yet its interplay with genomic alterations during tumor evolution is poorly understood. To explore this, we performed reduced representation bisulfite sequencing on 217 tumor and matched normal regions from 59 patients with non-small cell lung cancer from the TRACERx study to deconvolve tumor methylation. We developed two metrics for integrative evolutionary analysis with DNA and RNA sequencing data.

Background: Identifying molecular alterations specific to advanced lung adenocarcinomas could provide insights into tumour progression and dissemination mechanisms.
Method: We analysed tumour samples, either from locoregional lesions or distant metastases, from patients with advanced lung adenocarcinoma from the SAFIR02-Lung trial by targeted sequencing of 45 cancer genes and comparative genomic hybridisation array and compared them to early tumours samples from The Cancer Genome Atlas.
Results: Differences in copy-number alterations frequencies suggest the involvement in tumour progression of LAMB3, TNN/KIAA0040/TNR, KRAS, DAB2, MYC, EPHA3 and VIPR2, and in metastatic dissemination of AREG, ZNF503, PAX8, MMP13, JAM3, and MTURN.
Intraoperative radiotherapy for resectable brain metastases: a systematic review and meta-analysis.

Background: In recent years, intraoperative radiotherapy (IORT) with low-energy X-rays is emerging as an alternative to postoperative stereotactic radiotherapy (SRT) of the resection cavity in patients with resectable brain metastases (BMs).
Methods: We performed a systematic review of the MEDLINE, Embase, and Scopus databases, including all original articles on IORT for resectable BMs from 2015 to 2025. Data on safety, local control, and survival outcomes were collected.

Objectives: The 9th edition of the Tumor, Node, Metastasis (TNM-9) lung cancer classification is set to replace the 8th edition (TNM-8) starting in 2025. Key updates include the splitting of the mediastinal nodal category N2 into single- and multiple-station involvement, as well as the classification of multiple extrathoracic metastatic lesions as involving a single organ system (M1c1) or multiple organ systems (M1c2). This study aimed to assess how the TNM-9 revisions affect the final staging of lung cancer patients and how these changes correlate with overall survival (OS).
