CITED4 enhances the metastatic potential of lung adenocarcinoma

CITED4 expression is significantly upregulated in ADC tissues and cells. CITED4 interacted with CTNNB1 and functioned synergistically to enhance CLDN3 transcription. The CITED4-CTNNB1-CLDN3 axis plays a key role in the invasion and metastasis of ADC and provides a novel therapeutic target for lung cancer treatment.

Identification of differentially expressed circular RNAs associated with thymoma

The expression levels of hsa_circ_0001173, hsa_circ_0007291, hsa_circ_0003550, and hsa_circ_0001947 were significantly upregulated and positively correlated with immune imbalance in thymoma patients. The discovery of new differentially expressed circRNAs can be used not only as a biomarker for diagnosis, but also as a potential target for the treatment of thymoma.

Long-term outcomes of high-dose (74 GyE) proton beam therapy with concurrent chemotherapy for stage III nonsmall-cell lung cancer

Forty-five patients with stage III non-small cell lung cancer (14 stage IIIA, 31 stage IIIB) who received high-dose (74 GyE) passive-scattering proton beam therapy (PBT) with concurrent chemotherapy were retrospectively reviewed to analyze survivals and toxicities. The 3- and 5-year overall survival rates were 63.7% and 38.8%, respectively, and the median overall survival was 49.1 months. Passive-scattering PBT of 74 GyE with chemotherapy showed favorable survival and a low incidence of severe adverse events in patients with stage III NSCLC.

Is major pathologic response sufficient to predict survival in resectable nonsmall-cell lung cancer patients receiving neoadjuvant chemotherapy?

Pathologic response and nodal status of 194 nonsmall-cell lung cancer patients who received neoadjuvant chemotherapy and surgery were investigated. We demonstrated that major pathologic response was not adequate to predict survival, but when combined with nodal downstaging it could improve the efficacy of predicting survival in these patients. This helped to identify the population subset with the most favorable prognosis.

Biglycan, tumor endothelial cell secreting proteoglycan, as possible biomarker for lung cancer

We found that biglycan (BGN) is expressed in tumor endothelial cells (TECs) and that BGN expression in TECs is associated with tumor progression and prognosis in lung cancer. Moreover, BGN expression in preoperative serum was significantly associated with BGN expression in TECs and with tumor malignancy.

Management of chyle leakage after general thoracic surgery: Impact of thoracic duct embolization

After the introduction of thoracic duct embolization (TDE), only three of 48 patients underwent surgical ligation of thoracic duct. The length of hospital stay of patients who underwent lung cancer surgery was shorter than that before the introduction of TDE. This study demonstrated that TDE is an effective method for the management of postoperative chyle leakage and can help avoid invasive surgery in this group of patients.

A retrospective analysis of pembrolizumab plus chemotherapy versus pembrolizumab monotherapy for advanced or recurrent non-small cell lung cancer

There was no significant difference in clinical response and prognosis between the combination therapy group and the monotherapy group. We think that the higher frequency of treatment discontinuation due to adverse events in the combination therapy group compared to the monotherapy group is one reason why there was no significant difference in prognosis between the two groups.

Feasibility investigation of near-infrared fluorescence imaging with intravenous indocyanine green method in uniport video-assisted thoracoscopic anatomical segmentectomy for identifying the intersegmental boundary line

  • Pages: 1407-1414
  • First Published: 16 March 2021

Based on a large amount of clinical data, we found that the identification rate of IBL via ICGF-based method is comparable to the traditional MID method which is the globally accepted. Our study shows that the ICGF-based method can highly accurately identify the IBL and make anatomical segmentectomy easier and faster, and it helps to ensure sufficient resection margins, and therefore has the potential to be a feasible and effective technique to facilitate the quality of uniport VATS segmentectomy.

Pseudomesotheliomatous carcinoma of lung adenocarcinoma diagnosed using transesophageal ultrasound-guided bronchoscopic aspiration

Endoscopic ultrasound with bronchoscope-guided fine-needle aspiration (EUS-B-FNA), a minimally invasive procedure, may be useful for the diagnosis of pseudomesotheliomatous (PMC) carcinoma because a sufficient amount of tissue can be obtained for diagnosis. This is the first report of PMC diagnosed using EUS-B-FNA. Our findings suggest that EUS-B-FNA may reduce the risk of dissemination for PMC.

Handling benign interlobar lymphadenopathy during thoracoscopic lobectomy

Calcified or inflammatory lymph nodes between the target bronchus and pulmonary artery is a huge challenge when performing thoracoscopic lobectomy. Here, we report a strategy to handle this clinical situation. A needle was passed across the nodes and the target vessel was closed with a proximal and distal suture, and then gradually transected with scissors. After dissection of adenopathies, the target bronchus was stapled.
