Metachronous Lung Cancer: Clinical Characteristics and Effects of Surgical Treatment

Synchronous Endobronchial Carcinoid Tumor and Adenocarcinoma of the Lung: A Case Report and Review of the Literature

Diagnosis of synchronous multiple primary lung cancers (SMPLCs) is a challenge as multiple lesions on chest CT imaging can be misdiagnosed as more common entities such as metastatic disease or infections. The possibility of multiple primary lung cancers should always be considered. Accurate diagnosis can significantly change the management and prognosis. We report a case of a 57-year-old woman, an ex-smoker with chronic obstructive pulmonary disease (COPD), who was found to have synchronous endobronchial carcinoid tumor and adenocarcinoma of the lung. The association of carcinoid tumors and adenocarcinoma of the lung has been infrequently reported, with only a handful of cases published to date. Early diagnosis of resectable tumors can improve survival in patients with SMPLCs.

Clinical study of systemic chemotherapy combined with bronchoscopic interventional cryotherapy in the treatment of lung cancer

Background

This study is designed to investigate the clinical value of systemic chemotherapy combined with bronchoscopic interventional cryotherapy in the treatment of lung cancer.

Methods

A total of 412 lung cancer patients admitted to Cangzhou People’s Hospital from March 2018 to March 2020 were collected and divided into test group and control group based on their treatment schedules. The test group received systemic chemotherapy combined with bronchoscopic interventional cryotherapy, while the control group received systemic chemotherapy alone. Tumor objective response rate (ORR), disease control rate (DCR), serum tumor marker levels, serum matrix metalloproteinase (MMP) content, T cell subset level, survival time and adverse reactions of the two groups were observed.

Results

The ORR and DCR of the test group were better than those of the control group, while those of the non-small cell lung cancer (NSCLC) patients in the test group were better than patients with small-cell lung cancer (SCLC) (P <  0.05). There was no significant difference in serum tumor marker levels, MMP content and T cell subset level between the two groups before treatment. After treatment, the serum tumor marker levels along with serum MMP-2, MMP-9 and CD8⁺ levels in the test group decreased more remarkably, while CD4⁺ and CD4⁺/CD8⁺ levels increased more significantly than those in the control group (P <  0.05). The serum MMP-2 and MMP-9 of NSCLC patients in the test group decreased more remarkably than those of SCLC patients, while there was no significant difference in CD8⁺, CD4⁺ and CD4⁺/CD8⁺. The progression-free survival and overall survival of the test group were obviously longer than those of the control group. The same trend was observed in NSCLC patients compared with SCLC patients in the test group (P <  0.05).

Conclusions

Systemic chemotherapy combined with bronchoscopic interventional cryotherapy for lung cancer has good clinical efficacy and safety, and can be widely used in clinical practice.

Systems pharmacology uncover the mechanism of anti-non-small cell lung cancer for Hedyotis diffusa Willd

Non-small cell lung cancer (NSCLC) has become one of the most general malignancies in the world and has been shown to be the leading cause of cancer-related deaths. Traditional Chinese medicine (TCM) is considered to be a useful medicine for survival, and has been used in Asia for thousands of years. Hedyotis diffusa Willd (HDW) is an important folk herb that is used in clinical treatment of various cancers in various Chinese medicine prescriptions. However, its underlying mechanism of action remains unclear. Presently, we used an innovative system-pharmacology platform to systematically uncover the pharmacological mechanisms of HDW in the treatment of NSCLC from molecules, targets, and pathway levels. The results show that HDW treatment of NSCLC may activate immunity, achieve anti-inflammatory, anti-proliferative and anti-migration therapeutic effects by regulating multiple pathways. This research provides a new idea for understanding the mechanism of TCM and promotes to develop potential drugs from HDW in modern medicine.
