Abstract
ABSTRACT Lung cancer continues to be the leading cause of cancer-related death in the world, which is classically subgrouped into two major histological types: Non-small cell lung cancer (NSCLC) (85% of patients) and small-cell lung cancer (SCLC) (15%). Tumor location has been reported to be associated with the prognosis of various solid tumors. Several types of cancer often occur in a specific region and are more prone to spread to predilection locations, including colorectal cancer, prostate cancer, gastric cancer, ovarian cancer, cervical cancer, bladder cancer, lung tumor, and so on. Besides, tumor location is also considered as a risk factor for lung neoplasm with chronic obstructive pulmonary disease/emphysema. Additionally, the primary lung cancer location is associated with specific lymph node metastasis. And the recent analysis has shown that the primary location may affect metastasis pattern in metastatic NSCLC based on a large population. Numerous studies have enrolled the "location" factor in the risk model. Anatomy location and lobe-specific location are both important in prognosis. Therefore, it is important for us to clarify the characteristics about tumor location according to various definitions. However, the inconsistent definitions about tumor location among different articles are controversial. It is also a significant guidance in multimode therapy in the present time. In this review, we mainly aim to provide a new insight about tumor location, including anatomy, clinicopathology, and prognosis in patients with lung neoplasm.

JOURNAL OF ONCOLOGY 2020; 2020:6615575. [PMID: 33488709 PMCID: PMC7787720 DOI: 10.1155/2020/6615575] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 11/19/2020] [Accepted: 11/23/2020] [Indexed: 12/13/2022]
Abstract
Lung cancer is still the leading cause of cancer-related death worldwide. Of lung cancer, lung adenocarcinoma (LUAD) is the most common subtype. Most patients with LUAD would develop into metastasis, which limits the available treatment. Targeted therapy and immunotherapy provided options for those advanced patients. But they also broached up challenges to identify the appropriate patients. This study aims to reveal the landscapes of genomic mutations in primary and metastatic LUAD and their actionability. This study enrolled 636 patients with LUAD, of whom 85 and 551 were from patients with and without metastasis, respectively. Next-generation sequencing technology was used to retrieve their genomic information. Genomic mutations including short nucleotide variation, long variation, copy number variations, and fusions were called. The corresponding actionability was revealed. A comparison of genomic mutations and actionability between primary and metastatic LUAD was performed. In primary tumors, BRCA2 and FAT3 were significantly mutated in older patients; while in metastases, ALK and NOTCH2 were significantly mutated in younger patients. Primary tumors in male patients were significantly mutated in LRP1B and KRAS. Compared to primary tumors, metastases harbored less short nucleotide variations but more copy number variations and fusions. In metastases, chromosome 1 and chromosome 9 had less short nucleotide variations and more CNV than in primary tumors. Genomic variations of activated dendritic cells were more frequently mutated in metastases. EGFR genomic variations were negatively associated with PD-L1 and TMB. Patients with EGFR inhibitor treatment tend to have lower PD-L1 expression. The revealed discrepancy between primary and metastatic lung cancer could help guide the treatment strategies and the development of novel drugs.

[PMID: 30628193 PMCID: PMC6397910 DOI: 10.1111/1759-7714.12959] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2018] [Revised: 11/23/2018] [Accepted: 12/06/2018] [Indexed: 12/14/2022] Open
Abstract
Background Primary tumors located in the right and left side have distinctive prognoses, but the details have not been fully identified in non‐small cell lung cancer (NSCLC). This study investigated the impact of primary tumor side on long‐term survival in NSCLC patients. Methods Data of 90 407 patients from the Surveillance, Epidemiology, and End Results (SEER) Program were analyzed. To avoid bias between groups, we used innovative propensity score matching (PSM) analysis. Results There was no significant distinction in overall survival (OS) between right (n = 53 496) and left (n = 36 911) side tumors (hazard ratio [HR] 0.993, 95% confidence interval [CI] 0.9756–1.011; P = 0.432). Left side was associated with superior five‐year cancer‐specific survival (CSS) compared to right side NSCLC (HR 0.977, 95% CI 0.9574–0.9969; P = 0.024). No significant difference was observed in OS (P = 0.689) or CSS (P = 0.288) after PSM analysis. In the 51 319 patients who underwent surgery, left side (n = 21 245) was associated with poor OS compared to right side (n = 30 074) NSCLC (HR 1.039, 95% CI 1.011–1.067; P = 0.006), while CSS was similar (HR 1.031, 95% CI 0.997–1.065; P = 0.069). In patients who underwent surgery, there was also no significant difference in OS (P = 0.986) or CSS (P = 0.979) after PSM analysis. Conclusion The prognosis between right and left side NSCLC in stage I–IIIA was similar regardless of whether patients underwent surgery. Primary tumor side cannot be considered a prognostic factor when choosing appropriate treatment.

Peripheral lung adenocarcinomas harboring epithelial growth factor receptor mutations with microRNA-135b overexpression are more likely to invade visceral pleura. Oncol Lett 2017; 14:7931-7940. [PMID: 29250182 DOI: 10.3892/ol.2017.7195] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2016] [Accepted: 08/11/2017] [Indexed: 01/15/2023] Open
Abstract
Lung adenocarcinoma, characterized by its early and aggressive local invasion and high metastatic potential, is the most frequently observed histological type of non-small-cell lung cancer (NSCLC). Visceral pleural invasion (VPI) caused by peripheral lung adenocarcinomas is closely associated with the poor prognosis of patients with NSCLC. The association between VPI and some clinicopathological characteristics has been observed in the past few decades. However, the molecular mechanism of VPI in lung adenocarcinomas is unknown. In the present, the expression level of microRNA (miR-)135b and epidermal growth factor receptor (EGFR) mutations using the reverse transcription-quantitative polymerase chain reaction and DNA sequencing, respectively. In addition, the present study aimed at exploring the association between the miR-135b level, EGFR mutations and VPI in peripheral lung adenocarcinoma. The results of the present study demonstrated that miR-135b was significantly upregulated in lung adenocarcinoma compared with adjacent normal tissue and positively associated EGFR mutations in peripheral lung adenocarcinoma. Furthermore, it was identified that lung adenocarcinomas with EGFR mutations and miR-135b overexpression were more likely to invade visceral pleura. Taken together, these findings indicate that miR-135b overexpression is positively associated with mutations to EGFR, which may promote the development of peripheral lung adenocarcinomas by the formation of VPI. This indicates that the two factors may serve as prognostic markers and molecular targets for the treatment of peripheral lung adenocarcinomas.

Abstract
Histone acetyltransferases (HATs) play vital functions in the tumorigenesis of many solid organ malignancies. We previously screened a human HATs cDNA library and identified Tat-interactive protein-60KDa (TIP60) as a candidate critical HATs in the origination of lung cancer. In this study, our data suggested that overexpression of TIP60 inhibited the cell viability of A549 and H1299 cells since day 2. Compared to the control group, the viability of these two lung cancer cells was inhibited by 25% and 19% at day 6 with the overexpression of TIP60. It increased by 36% and 26% when TIP60 was knockdown for 6 days. The invasion ability of these two cells was also restrained when TIP60 was overexpressed. While knockdown of TIP60 had the opposite effect. Inhibition of TIP60 significantly promoted the expression of molecules in AKT signaling pathway especially c-Myc. Furthermore, compared to paired tumor-adjacent tissue, lung cancer tumors had low expression of TIP60. Therefore, we concluded that TIP60 might inhibit the viability and invasion ability of lung cancer cells through down-regulation of AKT signaling pathway.

Abstract
Background Tongue cancer is still one of the leading causes of mortality around the world. Recently, the ubiquitin system has been established as a critical modulator of tumors. In order to find the oral cancer related E3 ubiquitin ligases, we screened the human E3 ubiquitin ligase library and found that RING finger protein 139 (RNF139) regulated the biological behavior of tongue cancer cells. Methods MTT assay was used to analyze the cell viability changes of tongue cancer SCC9 and SCC25 cells caused by RNF139. The invasion ability of SCC9 and SCC25 cells with or without the knockdown of RNF139 was evaluated through transwell assay. The immunoblotting was recruited to determine the expression level of RNF139 in human tongue cancer tissues and para-carcinoma tissues. The effect of RNF139 on tumorigenicity of tongue cancer cells was analyzed by xenograft model on immunodeficient Balb/c nude mice. Results Overexpression of RNF139 inhibits the viability of tongue cancer cells since day 2. The colony formation ability of SCC9 and SCC25 cells was also decreased with the overexpression of RNF139. Knockdown of RNF139 significantly promoted the invasion ability of SCC9 and SCC25 cells. Furthermore, knockdown of RNF139 also induced the activation of AKT signaling pathway. While human tongue cancer tissues had low expression of RNF139. In nude mice, knockdown of RNF139 promoted the tumorigenicity of the SCC25 cells. Conclusions Our data establish a role for RNF139 in regulating the progression of tongue cancer.

Abstract
Due to recent advances in high-resolution detection technology, multiple primary lung cancer (MPLC) is becoming an increasingly common diagnosis. However, the genotype-phenotype correlations in MPLC patients have not yet been assessed. In this study, we analyzed the clinical and pathological data for 129 consecutive MPLC patients who received curative surgery at the Tongji University Shanghai Pulmonary Hospital, China. We have screened 129 patients in the present study and found mutations in EGFR, BRAF, ROS1 and KRAS genes, as well as the rearrangement of the EML4-ALK gene in 113 patients. The mean patient age was 59.9 (25-78) years old and 41 patients were males (31.8%). Among the total patients, 123 (95.4%) had two primary lesions, 5 (3.9%) had three primary lesions, and 1 (0.8%) had four primary lesions. In 38.8% of the patients, all lesions were located on only one side of the body. Most of the detected mutations (98 patients) were in the EGFR gene. The patients exhibited significant differences in the EGFR mutation, age at diagnosis, and foci location.

Abstract
This study aims to analyze the role of RNF126 in the oncogenesis of tongue cancer. The cell proliferation and viability of human tongue cancer cells, SCC25 and SCC9 cells, were determined by cell counting and MTT assay, respectively. The effect of RNF126 on regulating AKT signaling pathway was analyzed through western blotting. The transplantation tumor model of nude mice was used to evaluate the tumorigenecity of RNF126. Knockdown of RNF126 inhibited the proliferation and viability of SCC9 and SCC25 cells. Inhibition of RNF126 also decreased the activity of AKT1 as well as its downstream molecules. Furthermore, RNF126 regulated the tumor volume on mice model. These data suggested that RNF126 might be related to the progression of tongue cancer through regulating AKT signaling pathway.
