Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality worldwide. Standard treatment such as chemotherapy, radiotherapy, and surgery have many limitations in the treatment of this disease. Therefore, new molecular-targeted therapies needed and being developed. Patients with advanced NSCLC have a short life expentancy; therefore, in addition to increasing their survival, improving their quality of life (QoL) is also an important treatment goal. In this case report, we introduce NSCLC patient treated with Allergen Removed Rhus Verniciflua Stokes(aRVS). In this case, survival time incresed as traditional korean medicine using aRVS. And the general condition of the patient became better. Further case study will be needed in order to determine the effects of aRVS on NSCLC.

Lobectomy is considered the standard strategy for early-stage non-small cell lung cancer (NSCLC). However, sublobar resection for NSCLC has recently received increased attention. The objective of this study was to compare 5-year survival, recurrence-free survival, postoperative mortality, and postoperative morbidities in patients who received segmentectomy versus those who received lobectomy through a meta-analysis. Sixteen studies were included and the combined hazard ratios or odds ratios were calculated. The results revealed that the 5-year survival rate after segmentectomy was comparable to that of lobectomy for stage IA NSCLC. However, segmentectomy for stage I NSCLC had lower rates of postoperative mortality and morbidities than lobectomy.

After the successful development of targeted therapy and immunotherapy for the treatment of advanced-stage non-small cell lung cancer (NSCLC), these innovative treatment options are rapidly being applied in the adjuvant setting for early-stage NSCLC. Some adjuvants that have recently been approved include osimertinib for epidermal growth factor receptor-mutated tumors and atezolizumab and pembrolizumab for selected patients with resectable NSCLC. Numerous studies on various targeted therapies and immunotherapy with or without chemotherapy are currently ongoing in the adjuvant setting. However, several questions regarding optimal strategies for adjuvant treatment remain unanswered. The present review summarizes the available literature, focusing on recent advances and ongoing trials with targeted therapy and immunotherapy in the adjuvant treatment of early-stage NSCLC.

Background: The resection of recurrent non-small cell lung cancer can be performed very rarely. There has been many arguments for longterm result and therapeutic role in surgical management of recurrent non-small cell lung cancer(NSCLC). We analyze our result of surgical re-resection of recurrent NSCLC for 10 years retrospectively. Material and Method: In the period from 1987 to 1997, 702 patients who had been confirmed for NSCLC had undergone complete resection in Seoul National University Hospital. As December 1997, 22 of these patients have been operated on the diagnosis of recurrent lung cancer. In these patients one has revealed for benign nodule at postoperative pathologic pathologic was unresectable. and two had revealed other cell type on postoperative pathologic examination. Analysis about postoperative survival rate and the factors that influence postoperative survival rate - sex, age, pathologic stage, cell type, operation adjuvant therapy after first and second operation location of recurrence disease free survival-was 59.1$\pm$10.9 year. There were 14 men and 3 women. Four patients was received radiation therpy after first opration and two patients was received postoperative chemotherapy. At first operation 2 patients was stage Ia, 8 was stage Ib, 1 was stage IIa 6 was stage IIb. Eleven patients had squamous. cell carcinoma at postoperatrive pathologic examination five had adenocarcinoma and one had bronchioalveolar carcinoma. In second operation 8 patients were received limited resection. 9 were received lobectomy or pneumonectomy. One-year survival rate was 82.4% and five-year survival rate was 58.2% Non-adjuvant therapy group after initial operation was more survived than adjuvant therapy group statistically. Conclusion: operation was more survived than adjuvant therapy group statistically. Conclusion : Operation was feasible treatment modality for re-resectable non-small cell lung cancer. But we cannot rule out possibility of double primary lung cancer for them. Postoperative prognostic factor was adjuvant therapy or nor after first oepration but further study of large scale is needed for stastically more valuable result.

The SH2B1 adaptor protein is recruited to multiple ligand-activated receptor tyrosine kinases that play important role in the physiologic and pathologic features of many cancers. The purpose of this study was to assess SH2B1 expression and to explore its contribution to the non-small cell lung cancer (NSCLC). Methods: SH2B1 expression in 114 primary NSCLC tissue specimens was analyzed by immunohistochemistry and correlated with clinicopathological parameters and patients' outcome. Additionally, 15 paired NSCLC background tissues, 5 NSCLC cell lines and a normal HBE cell line were evaluated for SH2B1 expression by RT-PCR and immunoblotting, immunofluorescence being applied for the cell lines. Results: SH2B1 was found to be overexpressed in NSCLC tissues and NSCLC cell lines. More importantly, high SH2B1 expression was significantly associated with tumor grade, tumor size, clinical stage, lymph node metastasis, and recurrence respectively. Survival analysis demonstrated that patients with high SH2B1 expression had both poorer disease-free survival and overall survival than other patients. Multivariate Cox regression analysis revealed that SH2B1 overexpression was an independent prognostic factor for patients with NSCLC. Conclusions: Our findings suggest that the SH2B1 protein may contribute to the malignant progression of NSCLC and could offer a novel prognostic indicator for patients with NSCLC.

The outcomes of first-generation EGFR-TKIs (Gefitnib and Erlotinib) have shown great advantages over traditional treatment strategies in patients with non-small cell lung cancer (NSCLC), but unfortunately we have to face the situation that most patients still fail to respond in the long term despite initially good control. Up to now, the mechanism of acquired resistance to EGFR-TKIs has not been fully clarified. Herein, we sought to compile the available clinical reports in the hope to better understanding the subsequent treatment choices, particularly on whether restoring after a drug holiday or switching to another EGFR-TKI is the better option after failure of one kind of EGFR-TKI.

Stage 3 non-small cell lung cancer (NSCLC) exhibits significant diversity, making it challenging to define an optimal treatment. A collaborative multidisciplinary approach is essential in crafting individualized treatments. Previously, targeted therapies and immunotherapies were commonly used to treat patients with advanced and metastatic lung cancer. Such treatments are now being extended to individuals considered surgery, as well as patients once considered unsuitable for surgery. These changes have increased surgical success and substantially reduced postoperative recurrence. However, the possibility of severe adverse effects from immunotherapy can deter some patients from performing surgery. It is essential to carefully explore the clinical traits and biomarkers of patients who may benefit the most from immunotherapy, and patients for whom immunotherapy should not be prescribed. In summary, it's crucial to effectively integrate the latest immunotherapy in treating stage 3 NSCLC patients, thereby increasing their opportunities for surgical intervention, and ensuring they receive the best possible care.

Mediator 19 (Med19) is a component of the mediator complex which is a coactivator for DNA-binding factors that activate transcription via RNA polymerase II. Accumulating evidence has shown that Med19 plays important roles in cancer cell proliferation and tumorigenesis. The involvement of Med19 in sensitivity to the chemotherapeutic agent cisplatin was here investigated. We employed RNA interference to reduce Med19 expression in human non-small cell lung cancer (NSCLC) cell lines and analyzed their phenotypic changes. The results showed that after Med19 siRNA transfection, expression of Med19 mRNA and protein was dramatically reduced (p<0.05). Meanwhile, impaired growth potential, arrested cell cycle at G0/G1 phase and enhanced sensitivity to cisplatin were exhibited. Apoptosis and caspase-3 activity were increased when cells were exposed to Med19 siRNA and/or cisplatin. The present findings suggest that Med19 facilitates tumorigenic properties of NSCLC cells and knockdown of Med19 may be a rational therapeutic tool for lung cancer cisplatin sensitization.

Lung cancer remains the leading cause of cancer-related death throughout the world. Non-small cell lung cancer(NSCLC) is the most deadly form of lung cancer. Patients with non-small cell lung cancer are often found to be unavailable for operation at primary diagnosis. They are typically given conventional chemotherapy. When the tumor progresses during chemotherapy, a change in regimen is considered. The average period of administration differs with the regimen. In this case report, the authors introduce two cases of non-small cell lung cancer patients treated with allergen removed Rhus verniciflua stokes based herbal medicine along with pemetrexed($Alimta^{(R)}$) and erlotinib($Tarceva^{(R)}$). The authors report this case because these molecular-targeted agents were used for longer periods than expected, while improving the performance and other symptoms. Further studies illuminating the synergistic effects through conjunctive treatment with both conventional and Eastern medicine in lung cancer treatment should be performed in the future.

Lung cancer is a serious health problem and leading cause of death worldwide due to its high incidence and mortality. More than 80% of lung cancers feature a non-small cell histology. Over few decades, systemic chemotherapy and surgery are the only treatment options in this type of tumor but due to their limited efficacy and overall poor survival of patients, there is an urge to develop newer therapeutic strategies which circumvent the problems. Enhanced knowledge of translational science and molecular biology have revealed that lung tumors carry diverse driver gene mutations and adopt different intracellular pathways leading to carcinogenesis. Hence, the development of targeted agents against molecular subgroups harboring critical mutations is an attractive approach for therapeutic treatment. Targeted therapies are clearly more preferred nowadays over systemic therapies because they target tumor specific molecules resulting with enhanced activity and reduced toxicity to normal tissues. Thus, this review encompasses comprehensive updates on targeted therapies for the driver mutations in non-small cell lung cancer (NSCLC) and the potential challenges of acquired drug resistance faced i n the field of targeted therapy along with the imminent newer treatment modalities against lung cancer.
