Abstract
This study assesses miR-21’s role in non-small cell lung cancer (NSCLC) cells. miR-21/PTEN RNA level in normal and NSCLC cell (A549) was detected by qPCR. After transfection of miR-21 and inhibitors, cell proliferation was assessed by MTT. PTEN, NF-κB, p53, BCL2,
BAX levels were measured after si-PTEN transfection. miR-21 was significantly lower and PTEN was higher in NSCLC cells than normal cells (P <0.001) and PTEN was negatively associated with miR-21. MTT assay showed that cell survival rate was decreased after miR-21 was inhibited and
increased after miR-21 was overexpressed. After inhibiting PTEN, protein expression of proliferation-related factors NF-κB and p53 was decreased. TUNEL experiment showed elevated cell apoptosis after miR-21 was inhibited and decreased apoptosis after miR-21 was overexpressed.
Inhibition of PTEN modulated Akt signaling as demonstrated by no changes of Akt expression and decreased p-Akt level along with downregulated BCL2 and BAX. In conclusion, miR-21/PTEN inhibits NSCLC cell proliferation and promotes cell apoptosis.

J Thorac Dis 2022; 14:4285-4296. [PMID: 36524081 PMCID: PMC9745515 DOI: 10.21037/jtd-22-890] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Accepted: 09/23/2022] [Indexed: 01/22/2024]
Abstract
BACKGROUND The survival of patients with stage IA-IIA non-small cell lung cancer (NSCLC) after surgery is heterogeneous. This study aimed to construct a prognostic risk model to predict the overall survival (OS) of these patients. METHODS Data from patients (n=9,914) from the Surveillance Epidemiology and End Results (SEER) database were analyzed. The cases were randomly divided into the training and the validation groups. Patients from the Shanghai Pulmonary Hospital (n=270) were also included as an external cohort. Independent significant factors affecting survival in the training cohort were used to construct a nomogram. The precision was evaluated using the concordance index (C-index) and calibration plots. The X-tile software was used to confirm the optimal cut-off value to classify the patients. RESULTS Sex, age at diagnosis, tumor size, visceral pleura invasion (VPI), tumor grade, and the number of examined lymph nodes were deemed independent prognostic factors and were selected to establish the nomogram. The C-indices of the nomogram for predicting OS were 0.671 [95% confidence interval (CI): 0.653-0.689] in the training group, and 0.668 (95% CI: 0.650-0.687) and 0.707 (95% CI: 0.651-0.763) in the validation and the testing groups, respectively. The cut-off value of risk points was 106.0, which stratified the patients into high-risk and low-risk groups. The high-risk patients had shorter 5-year OS than low-risk patients (P<0.001). CONCLUSIONS The established nomogram could evaluate the survival in patients with stage IA-IIA NSCLC after surgery and may provide prognostic information for clinicians to make decisions in the management of adjuvant therapy.

[PMID: 35803556 DOI: 10.1016/j.pdpdt.2022.103001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2022] [Revised: 07/04/2022] [Accepted: 07/04/2022] [Indexed: 11/16/2022]
Abstract
Photodynamic therapy (PDT) is an FDA approved treatment for lung cancer. In the United States the photosensitizer porfimer sodium (Photofrin®, Pinnacle Biologics) is intravenously introduced at 2mg/kg. After approximately 48 h, illumination to activate the photosensitizer is initiated, with 630nm red light at 200J/cm, delivered by fiber-optic catheter, brought to the tumor endo- bronchially, and delivered for 500 s. This will create, in the presence of oxygen, a Type II Photodynamic Reaction (PDR) which generates singlet oxygen species that are tumor ablative. Classically, PDT for lung cancer has been employed for symptomatic central and obstructing tumors with great success. This case report describes an innovative approach to treat a peripheral, early stage lung cancer employing magnetic navigation and endobronchial treatment. We report on a 79 year old male with numerous comorbidities including pulmonary fibrosis, who was found to have a biopsy proven peripheral and solitary non-small cell cancer. Due to prior SBRT (stereotactic body radiation therapy) with dose levels causing radiation fibrosis, he was not a candidate for repeat SBRT, and he was not a surgical candidate due to comorbidities. Tumor control with PDT was achieved without treatment related morbidity. This report details our findings.

Abstract
Objectives Most non-metastatic cancer patients can harvest a preferable survival after surgical treatment, however, patients sometimes refuse the recommended cancer-directed surgery. It is necessary to uncover the factors associated with patent's decision in taking cancer surgery and explore racial/ethnic disparities in surgery refusal. Methods Based on the Surveillance, Epidemiology and End Results (SEER)-18 program, we extracted data of non-metastatic cancer patients who didn't undergo surgery. Ten common solid cancers were selected. Four racial/ethnic categories were included: White, black, Hispanic, and Asian/Pacific Islander (API). Primary outcome was patient's refusal of surgery. Multivariable logistic regression models were used, with reported odds ratio (OR) and 95% confidence interval (CI). Results Among 318,318 patients, the incidence of surgery refusal was 3.5%. Advanced age, female patients, earlier cancer stage, uninsured/Medicaid and unmarried patients were significantly associated with higher odds of surgery refusal. Black and API patients were more likely to refuse recommended surgery than white patients in overall cancer (black-white: adjusted OR, 1.18; 95% CI, 1.11–1.26; API-white: adjusted OR, 1.56; 95% CI, 1.41–1.72); those racial/ethnic disparities narrowed down after additionally adjusting for insurance type and marital status. In subgroup analysis, API-white disparities in surgery refusal widely existed in prostate, lung/bronchus, liver, and stomach cancers. Conclusions Patient's socioeconomic conditions reflected by insurance type and marital status may play a key role in racial/ethnic disparities in surgery refusal. Oncological surgeons should fully consider the barriers behind patient's refusal of recommended surgery, thus promoting patient-doctor shared decision-making and guiding patients to the most appropriate therapy.

Abstract
Current lung cancer diagnosis methods encounter delayed visual confirmation of tumor foci and low-resolution metrics in imaging findings, which delays the early treatment of tumors. Here, we developed a potent lung cancer imaging and treatment strategy centered around a nanotransformational concept of tumor iron mineralization in situ, which employs Prussian blue/calcium peroxide nanocomposites as a precursor. The resultant iron mineralization in tumor cells greatly facilitates the early and differential diagnosis of lung carcinoma from benign nodules via medical imaging, meanwhile introducing oxidative stress to activate the cellular apoptosis and ferroptosis pathways, resulting in inhibition of the malignant behavior of tumor cells. Tumor-microenvironment-triggered iron mineralization enables integration of the detection and prevention of tumor metastasis at its early stages with no assistance of toxic drugs, which offers a potential solution for the precise management of lung cancer with ideal outcomes.

Abstract
Objective: The objective of this research is to explore the diagnostic value of imaging plus tumor markers in the early detection of lung cancer. Methods: Sixty patients with lung cancer treated in our hospital from January 2018 to January 2019 were selected as group A. They were matched with 60 patients with benign lung disease as group B and 60 healthy subjects examined in our hospital as group C. The carcino-embryonic antigen (CEA), CYFRA21-1, and neuron-specific enolase (NSE) were assessed, and the diagnostic value of tumor markers plus imaging in lung cancer diagnosis was explored. Results: The CEA, CYFRA21-1, and NSE in group A were evidently superior to those in groups B and C, and those in group B were superior to those in group C (all P < 0.001). CEA had the highest sensitivity (56.7%), and NSE had the highest specificity (93.3%). The tumor markers plus imaging had the highest sensitivity for different types of lung cancer, and the sensitivity to early lung cancer (90%) was superior to other diagnostic methods (P < 0.05). Conclusion: The tumor markers plus imaging is of great significance in early lung cancer diagnosis and provides a reference for judging the pathological classification.
