Background: The immune checkpoint ligand, programmed cell death 1 ligand 1 (PD-L1), is expressed in various tumors and associated with response to drugs that target programmed cell death protein 1. Previous studies have estimated the level of PD-L1 expression among different stages of thymoma and thymic carcinoma to evaluate its potential use as a diagnostic factor; however, its varying expression level has been problematic. We conducted this meta-analysis of published literature to evaluate PD-L1 expression in thymomas and thymic carcinomas.

Objectives: Transforming anaplastic lymphoma kinase (ALK) gene rearrangements are well known as a unique subset of non-small cell lung cancer (NSCLC) with mutations other than EGFR. Currently, crizotinib is the standard first-line treatment for ALK-positive NSCLC.

Materials And Methods: With advances in detection methods, more and more uncommon ALK fusion partners have been identified.

Pulmonary involvement has been reported in >40% of autopsy series in patients with metastatic prostate cancer; however, isolated lung metastases have been documented in <1% of cases and 43.5% (10/23) cases underwent surgical resection and most of them have good outcome. We present a 74-year-old male Gleason high-grade prostate cancer patient with initially negative PSA and isolated pulmonary lesion which was confirmed as lung metastasis by resection.

Background: Whether or not mutation status detected by ddPCR in plasma predicts the effect of icotinib on patients with advanced lung adenocarcinoma was determined.

Methods: Plasma and matched tissue specimens from patients with advanced lung adenocarcinoma were collected prior to icotinib treatment. The ARMS method was used to detect mutation status in DNA extracted from tissue specimens, while the mutation status in ctDNA extracted from plasma specimens was determined by ddPCR.

Chromosomal translocation resulting in the fusion between the echinoderm microtubule-associated protein-like 4 () gene and the anaplastic lymphoma kinase () gene has been considered as a novel oncogenic fusion in a subset of non-small cell lung cancer (NSCLC), mostly in non-smokers with adenocarcinoma. EML4-ALK translocations are commonly reported to be mutually exclusive with epidermal growth factor receptor (EGFR) or KRAS mutations. Herein, we reported a rare case of 47-year-old female was diagnosed with lung adenocarcinoma and treated with three cycles of chemotherapy.

Article Synopsis
  • Non-small cell lung cancer (NSCLC) is the top cause of cancer-related deaths, and Compound K, derived from ginsenosides, shows potential anti-cancer effects on NSCLC cells.
  • The study found that Compound K reduces the viability of NSCLC cells and lowers glucose uptake and lactate production, also inhibiting key enzymes related to glucose metabolism.
  • Compound K's effectiveness is linked to its ability to suppress HIF-1α and GLUT1 expression, indicating it could be a novel treatment targeting glucose metabolism in NSCLC.

C-ros oncogene 1 receptor tyrosine kinase () rearrangement forms a novel molecular subgroup of non-small cell lung cancer (NSCLC). The present study explored the clinicopathological features and clinical efficacy of crizotinib in patients with -positive NSCLC. A retrospective analysis of 2,617 cases of NSCLC diagnosed between January 2013 and December 2016 was performed.

This study aimed to systematically evaluate the value of combined detection of serum CEA and CA125 concentrations for the diagnosis of lung cancer. Related studies regarding the diagnosis of lung cancer were searched in PubMed, Embase, CNKI, and Wanfang using a computer. The number of patients who were true-positive, false-positive, false-negative, and true-negative were extracted from each study.

Small intestinal metastases from primary lung cancer are rare. Such patients have a poor prognosis. Early diagnosis of small intestinal metastases is difficult because of the low incidence of clinically apparent symptoms.

Many studies conducted on the relationship between serum iron levels and lung cancer risk had produced inconsistent results. We therefore conducted a meta-analysis to determine whether serum iron levels were lower in lung cancer patients compared to those in controls.A literature survey was conducted by searching the PubMed, WanFang, CNKI, and SinoMed databases for articles published as of Mar 1, 2018.

Accumulating evidences have indicated that BIM expression largely decides the development of lung cancer and outcome of EGFR-mutant lung cancers after TKI treatments. BIM polymorphism is a 2,903-bp deletion in the second exon. To clarify the relationship between this BIM polymorphism and clinical outcomes of lung cancers, we conducted this meta-analysis and observed the survival and responses to TKIs.

In non-small cell lung cancer (NSCLC), driver gene alterations, such as , and , are usually mutually exclusive. Few clinical cases with co-existing fusion and de-novo amplification have been reported. In addition, the efficacy of crizotinib in Chinese patients with driver co-existing alterations is uncertain.

ALK rearrangement is a driver gene in non-small cell lung cancer (NSCLC). ALK-positive tumors are sensitive to ALK-tyrosine kinase inhibitors (TKIs). The detection of key driver genes is crucial to enable personalized treatment.

ROS1 rearrangement is a validated therapeutic driver gene in non-small cell lung cancer (NSCLC) and represents a small subset (1-2%) of NSCLC. A total of 17 different fusion partner genes of ROS1 in NSCLC have been reported. The multi-targeted MET/ALK/ROS1 tyrosine kinase inhibitor (TKI) crizotinib has demonstrated remarkable efficacy in ROS1-rearranged NSCLC.

The most frequent epidermal growth factor receptor (EGFR) mutations of lung cancer include exon 19 in deletion and the exon 21 L858R mutation. And EGFR-tyrosine kinase inhibitor (TKI) as the standard first line treatment show good response to classical/sensitizing EGFR mutations. With the development of detection methods, some uncommon genomic mutation events such as exon 18-25 kinase domain duplications (KDD) and EGFR rearrangements (EGFR-RAD51 or EGFR-PURB) are found.

We report a case of concomitant EML4-ALK and TPM3-ROS1 fusion in non-small cell lung cancer (NSCLC) in a 47-year-old Chinese man and review the clinical characteristics of this type double of fusion. The patient presented with a local tumor of the left upper lobe and underwent thoracoscopy. Postoperative surgical pathologic staging revealed T N M stage IA.

Lung adenocarcinomas with gene rearrangement in the receptor tyrosine kinase ROS1 have emerged as a rare molecular subtype. Although these lung adenocarcinomas respond to ROS1tyrosine kinase inhibitors, many patients ultimately acquire resistance. ROS1gene rearrangement is generally mutually exclusive with other driver genomic alterations, such as those in EGFR, KRAS, or ALK, thus multiple genomic alterations are extremely rare.

ROS1 rearrangement occurs in 1-2% of non-small cell lung cancer (NSCLC) cases. These patients would benefit from treatment with the anaplastic lymphoma kinase inhibitor, crizotinib; however, resistance to crizotinib inevitably develops in such patients despite an initial response. The mechanism of acquired resistance to crizotinib in patients with NSCLC with ROS1 rearrangement has not yet been identified.

Hemangiomas of the rib are extremely rare benign neoplasm. Here we present a case in a 47-year-old female, detected by chest X-ray and underwent a surgical resection. Histologically, the tumor was composed of a homogeneous conglomerate, irregular, thin walled and dilated blood vessels containing red blood cells, supported by fibrous stroma and intermingled to regular bone trabeculae.
