  • 유전자 치료등 폐암에 대한 새로운 치료법의 개발및 그 효능의 검증에 있어 적절한 동물 모델이 없음은 큰 제 한점중의 하나이다. 특히 종양의 생물학적 특성이나 치료에의 효과등이 장기자체의 환경에 크게 영향 을 받는다는 사실은, 인체에서의 폐암의 특성을 가지며 폐에 정 위적으로 발생하는 폐암의 동물모델의 개발 을 시급하게 한다. 저자등은 Nude rat을 대상 동물로 하여, 개흉하에 종양세포 부유액을 원하는 폐말단 부위에 직접 주입함으로 폐에 정 위적으로 폐암의 발달을 유도하였으며 이를 이용하여 발생된 비소세포 폐암의 병태를 연구하였다. 종양은 실험 대상 등물에서 모두 발생하였으며 이용한 두 가지 종류의 세포주(NCI-H46O과 NCI-H1299)에서 모두 효과적으로 발생하였다. 발생된 폐종양은 시간 경과에 따라 주위 조직으로의 침윤과 종격동 전이의 양상를 보였다. 종양 숙주 동물의 평균 수명은 약 5주 정도였다. 저자등이 개발한 비소세포폐암의 동물 모델은 기관지를 통한 종양 세포 주입법에 의한 폐암 모델에 비해 국소적으로 진행된 폐암을 원하는 부위에 정확히 만들 수 있음은 물론 외과적 처치를 비롯한 국소적 치료 방법의 개발이나 ?과의 검증에 두루 이용되기에 적절하다고 사료된다.

  • 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.

  • The lung adenocarcinoma is considered more aggressive than other types of non-small cell lung cancer. As metabolites of tryptophan degradation along the kynurenine pathway, including kynurenic acid, have been shown to induce immunosuppression and facilitate escape of tumor cells from immune surveillance, a hypothesis was set up that differences in biological behavior between types of lung cancer may be associated with altered activity of the kynurenine metabolic pathway. The aim of the study was to determine kynurenic acid levels in the serum of patients with bronchial adenocarcinoma for comparison with other types of non-small cell lung cancer. A total of 227 patients with non-small cell lung cancer were enrolled in the study, including 71 with adenocarcinoma and 96 with squamous cell carcinoma. Serum kynurenic acid concentration was determined with use of high performance liquid chromatography and fluorometry. The level of kynurenic acid in the serum of patients with adenocarcinoma was significantly higher than in those with squamous cell lung cancer ($107.1{\pm}62.8$ pmol/ml; 95%CI: 92.4 to 132.3 pmol/ml versus $82.1{\pm}47.6$ pmol/ml; 95%CI: 78.5 to 91.2 pmol/ml, respectively; p = 0.027). Differences between other histological types of lung cancer were insignificant. We conclude that increased activity of kynurenine metabolic pathway manifested by elevated serum kynurenic acid level may be one of the factors associated with clinically distinct biological behavior of adenocarcinoma, in particular high invasiveness and rapid progression.

  • Non-small cell lung cancer (NSCLC) is the most common type of lung cancer and that accounts for 85% of lung cancer patients. Although several EGFR-targeted drugs have been developed in the treatment of NSCLC, the clinical efficacy of EGFR-targeted drugs in NSCLC is limited by the occurrence of drug resistance. In this regard, Hsp90 represents great promise as a therapeutic target of cancer due to its potential to simultaneously disable multiple signaling pathways. In this study, we discovered that a natural product, flavokawain B disrupted Hsp90 chaperoning function and impaired the growth of gefitinib-resistant non-small cell lung cancer (H1975). The result suggested that flavokawain B could serve as a potential lead compound to overcome the drug resistance in cancer chemotherapy.

  • Objective: To demonstrate an improvement in metastatic cancer pain and a decrease in tumor size in a patient with non-small cell lung cancer. Method: A 53-year-old female patient diagnosed with metastatic non-small cell lung cancer in August 2022 underwent integrative cancer treatment (ICT) for two months to decrease the tumor size and improve back pain from bone metastasis. The patient underwent chemotherapy with ICT. Radiologic outcomes were assessed by chest, abdomen, and pelvis computed tomography based on the Response Evaluation Criteria in Solid Tumors (RECIST) protocol. Clinical outcomes were assessed using National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE), Eastern Cooperative Oncology Group (ECOG), and a numeric rating scale (NRS). Result: During the two months of treatment, the NRS scores for back pain were improved, and the ECOG score improved from grade 2 to 1. The size and metabolic activity of the primary lung tumor decreased and underwent partial remission based on RECIST. No serious side effects of grade 3 or higher were noted on the NCI-CTCAE test. Conclusion: This case suggests that ICT may have a therapeutic effect for cancer pain and a synergetic effect with chemotherapy for metastatic non-small cell lung cancer.

  • MiRNAs are endogenous, single stranded ~22-nucleotide non-coding RNAs (ncRNAs) which are transcribed by RNA polymerase II and mediate negative post-transcriptional gene regulation through binding to 3'untranslated regions (UTR), possibly open reading frames (ORFs) or 5'UTRs of target mRNAs. MiRNAs are involved in the normal physiology of eukaryotic cells, so dysregulation may be associated with diseases like cancer, and neurodegenerative, heart and other disorders. Among all cancers, lung cancer, with high incidence and mortality worldwide, is classified into two main groups: non-small cell lung cancer and small cell lung cancer. Recent promising studies suggest that gene expression profiles and miRNA signatures could be a useful step in a noninvasive, low-cost and repeatable screening process of lung cancer. Similarly, every stage of lung development during fetal life is associated with specific miRNAs. Since lung development and lung cancer phenomena share the same physiological, biological and molecular processes like cell proliferation, development and shared mRNA or expression regulation pathways, and according to data adopted from various studies, they may have partially shared miRNA signature. Thus, focusing on lung cancer in relation to lung development in miRNA studies might provide clues for lung cancer diagnosis and prognosis.

  • A total of eighty one patients with resected stage II and IIIA non-small cell lung cancer treated with postoperative adjuvant radiation therapy between Jan. 1971 and Dec. 1990 were retrospectively analysed to evaluate whether postoperative radiation therapy improves survival. Patterns of failure and prognostic factors were also analysed. The 5 year overall and disease free survival rate were 40.5%, 43.4% and median survival 30 months. The 5 year actuarial survival rates by stage II and IIIA were 53.9% and 36.2%. Loco-regional failure rate was 14.7% and distant metastasis rate was 33.3% and both 4%. Statistically significant prognostic factor affecting survival was presence of mediastinal lymph node metastasis[N2]. This retrospective study suggests that postoperative radiation therapy in resected stage II and IIIA non-small cell lung cancer can reduce loco-regional recurrence and may improve survival rate as compared with other studies which were treated by surgery alone.

  • 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.
