Department of Radiology, Sun Yat-sen University Cancer Center, State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, Guangzhou, China.

Background: With the development of tyrosine kinase inhibitor (TKI) treatment, the prognosis of advanced lung adenocarcinoma (LUAD) patients with epidermal growth factor receptor () mutations has been continuously improving. This study aims to propose the utilization of pathological characteristics and imaging features to evaluate the impact of gene mutations on the prognosis of T1-4N0M0 LUAD.

Methods: Among the cases diagnosed with LUAD between April 2015 and April 2016, 438 patients with T1-4N0M0 LUAD were included, and the clinical characteristics were collected.

Background: Systemic chemotherapy (SC) stands the only first-line treatment for advanced intrahepatic cholangiocarcinoma (iCCA) for the past few decades. Immune checkpoint inhibitors (ICIs) have been proved to provide additional benefit in disease control. However, oncological outcome of iCCA remains poor and awaits further improvement with new treatment modalities.

State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, Guangdong Provincial Clinical Research Center for Cancer, Sun Yat-sen University Cancer Center, Guangzhou 510060, P.R. China; Department of Urology, Sun Yat-sen University Cancer Center, Guangzhou 510060, P.R. China. Electronic address:

Predicting the histopathology of residual retroperitoneal masses (RMMs) before post-chemotherapy retroperitoneal lymph node dissection in metastatic nonseminomatous germ cell tumors (NSGCTs) can guide individualized treatment and minimize complications. Previous single approach-based models perform poorly in validation. Herein, we introduce a machine learning model that evolves from a single-dimensional tumor diameter to incorporate high-dimensional radiomic features, with its effectiveness assessed using the macro-average area under the receiver operating characteristic curves (AUCs).

The ribosomal RNA (rRNA) is one of the most heavily modified RNA species in nature. Although we have advanced knowledge of the sites, functions, and the enzymology of many of the rRNA modifications from all kingdoms of life, we lack basic understanding of many of those that are not universally present. A single N modified uridine base (mU) was identified to be present on the 28 rRNA from humans and frogs but absent in bacteria or yeast.

November 2024

Department of Radiation Oncology, State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, Guangdong Provincial Clinical Research Center for Cancer, Sun Yat-sen University Cancer Center, Guangzhou, China.

Article Synopsis
  • The study compares magnetic resonance imaging (MRI) and computed tomography (CT) for tumor delineation in patients with locally advanced non-small cell lung cancer undergoing hypo-fractionated concurrent chemoradiotherapy.
  • MRI provided better soft-tissue resolution, which resulted in a smaller planning target volume and fewer cases of severe toxicity compared to CT.
  • There were no significant differences in locoregional progression-free survival, progression-free survival, or overall survival between the MRI-based and CT-based groups.

Background: Subsequent lines of therapy for chemotherapy-resistant metastatic colorectal cancer (CRC) have shown limited efficacy. Herein, we retrospectively investigated the efficacy and safety of hepatic artery infusion chemotherapy (HAIC) using oxaliplatin plus 5-FU/FUDR in patients with unresectable colorectal liver metastases (CRLM) who progressed following standard chemotherapy regimens.

Methods: From March 2017 to April 2023, CRC patients with unresectable CRLM who progressed following standard chemotherapy and subsequently received HAIC oxaliplatin plus 5-FU/FUDR were evaluated.

ARID1A, a core constituent of SWI/SNF complex, is mutated in approximately 10% of colorectal cancers (CRC). While ARID1A deficiency corresponds to heightened immune activity in CRC, immune checkpoint inhibitors (ICIs) have shown limited efficacy in these tumors. The discovery of targetable vulnerabilities associated with ARID1A deficiency in CRC could expand treatment options for patients.

Regulatory factor X1 promotes sorafenib-induced ferroptosis in hepatocellular carcinoma by transcriptional regulation of BECN1.

Cell Oncol (Dordr)

December 2024

State Key Laboratory of Oncology in South China and Collaborative Innovation Center for Cancer Medicine, Sun Yat-Sen University Cancer Center, Guangzhou, China.

Article Synopsis
  • Sorafenib is a first-line drug for advanced hepatocellular carcinoma (HCC), which shows limited effectiveness, but may induce cell death through a process called ferroptosis.
  • The study identified a key regulatory factor, RFX1, that enhances ferroptosis in HCC cells by inhibiting a specific antiporter system and regulating the expression of the BECN1 gene.
  • Findings suggest a new signaling loop involving STAT3 that promotes RFX1 expression and helps explain how sorafenib leads to HCC cell death, offering insights for potential therapeutic strategies.

J Inflamm Res

December 2024

Department of Anesthesiology, Sun Yat-Sen University Cancer Center, State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, Guangzhou, People's Republic of China.

Article Synopsis
  • Meniere's disease (MD) is linked to problems with the endolymphatic sac (ES), but the specific molecular causes are still unclear.
  • A study compared the proteins in ES luminal fluids from MD patients and healthy controls, identifying significant differences—6 proteins were found to be expressed differently, with some increased and others decreased in MD patients.
  • The findings suggest that certain proteins indicate inflammation and oxidative damage in MD, and one protein, CD44, might be connected to the overproduction of endolymph in the condition.

Department of Radiation Oncology, Sun Yat-sen University Cancer Center, State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, Guangdong Key Laboratory of Nasopharyngeal Carcinoma Diagnosis and Therapy, Guangzhou 510060, China. Electronic address:

Nasopharyngeal carcinoma (NPC), historically termed 'lymphoepithelioma-like carcinoma' due to its rich lymphocyte infiltration, benefit from PD-1 blockade treatment. However, a comprehensive understanding of its tumor microenvironment (TME) remains elusive, hindering the identification of effective biomarkers for immunotherapy. We leveraged multimodal profiling data, including gene expression, immunohistochemistry, and multiplex immunohistochemistry, from three independent cohorts of NPC patients with a total of 327 patients to dissect the TME in NPC.

Article Synopsis
  • Deficiency in DNA-damage repair (DDR) genes is linked to a higher risk of lung cancer, especially due to rare loss-of-function variants, prompting research into the role of rare regulatory variants.* -
  • By analyzing whole-genome sequencing data from nearly 3,000 lung cancer patients and 3,000 controls, researchers identified 750 rare functional regulatory variants (frVars) that affect the transcriptional activity of DDR gene promoters, with a notable increase in these variants among lung cancer cases.* -
  • Specifically, down-regulated transcriptional variants (dr-frVars) were significantly associated with lung cancer risk, highlighting the importance of functional regulatory variants in DDR genes, alongside more commonly studied variants, in contributing to
