Aim: The T cell receptor–CD3 complex has shown great potential in tumor therapy. However, there is currently no research on CD3D in tumors. Materials & methods: Correlation between CD3D expression ...

Near-infrared (NIR) fluorescence imaging has been proved as an effective modality in identifying the tumor border and distinguishing the tumor cells from healthy tissue during the oncological surgery. Developing NIR fluorescent probes with high tumor to background (T/B) signal is essential for the complete debulking of the tumor, which will prolong the survival rate of tumor patients. However, the nonspecific binding and “always-on” properties of the conventional fluorescent probes leads to high background signals and poor specificity.

Colon cancer is one of the most malignant cancers worldwide. Nearly 20% of all colon cancer patients are diagnosed at stage IV (metastasis). However, further study of colon cancer is difficult due to a lack of understanding of its pathogenesis. In this study, we acquired high–throughput sequence data from TCGA datasets and performed integrated bioinformatic analysis including differential gene expression analysis, gene ontology and KEGG pathways analysis, protein–protein analysis, survival analysis, and multivariate Cox proportional hazards regression analysis in order to identify a panel of key candidate genes involved in the metastasis of colon cancer. We then constructed a prognostic signature based on the expression of REG1B, TGM6, NTF4, PNMA5, and HOXC13 which could provide significant prognostic value for colon cancer.

Background: Pulmonary tuberculosis (TB) is associated with an increased risk of lung cancer. Our study investigated whether the coexistence of an old pulmonary TB lesion is an independent prognostic factor for lung cancer survival in Chinese non-small cell lung cancer patients. Methods: We performed a retrospective review of 782 non-small cell lung cancer patients who underwent surgical resection as their primary treatment in 2006 and were followed for 5 years. The associations between lung cancer survival and the presence of old pulmonary TB lesions were assessed using Cox’s proportional hazard regression analysis adjusted for WHO performance status (PS), age, sex, smoking-status, tumor stage, and surgical approach. Results: Sixty-four of the patients had old pulmonary TB lesions. The median survival of squamous cell carcinoma patients with TB was significantly shorter than that of patients without TB (1.7 vs. 3.4 years, p < 0.01). The presence of an old pulmonary TB lesion is an independent predictor of poor survival with a hazard ratio (HR) of 1.72 (95% CI, 1.12–2.64) in the subgroup of squamous cell carcinoma patients studied. Conclusion: The presence of an old pulmonary TB lesion may be an important prognostic factor for predicting the survival of squamous cell carcinoma patients.

A 55-year-old man was re-admitted for persistent hemoptysis and high fever three weeks after an initial left upper sleeve lobectomy for a central squamous lung cancer tumor. Pulmonary artery pseudoaneurysm and pulmonary infection were confirmed by multidetector computed tomography angiography and subsequent emergency completion pneumonectomy. The development of pulmonary artery pseudoaneurysm, secondary to post-operative pulmonary infection and pulmonary vascular manipulation, is rare and prompt surgical manipulation is mandatory.
