  • Introduction: Lung cancer, the leading cause of cancer deaths, is divided into 2 main classes based on its biology, therapy and prognosis: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Many cases are at an advanced stage at diagnosis, which is a major obstacle to improving outcomes. It is important to define the high risk group patients for early diagnosis and chance of cure. Blood group antigens are chemical components on erythrocyte membranes but they are also expressed on a variety of epithelial cells. Links between ABO blood groups with benign or malignant diseases, such as gastric and pancreas cancers, have been observed for a long time. In this study, we aimed to investigate any possible relationship between lung cancer histological subtypes and ABO-Rh blood groups. Materials and Methods: The files of 307 pathologically confirmed lung cancer patients were reviewed retrospectively. Cases with a serologically determined blood group and Rh factor were included and those with a history of another primary cancer were excluded, leaving a total of 221. The distribution of blood groups of the lung cancer patients were compared with the distribution of blood groups of healthy donors admitted to the Turkish Red Crescent Blood Service in our city in the year 2012. Results: There was no significant difference between patients with lung cancer of either type and the control group in terms of distribution of ABO blood groups and Rh factor (p: 0.073). There was also no relationship with non small cell cancer histological subtypes. Conclusions: In this study, we found no relationship between the ABO-Rhesus blood groups and NSCLC and SCLC groups. To our knowledge this is the first analysis of ABO blood groups in SCLC patients.

  • Background: Lung cancer is the leading cause of cancer death, late diagnosis being the main obstacle to improving the outcomes with stage at diagnosis as an important prognostic factor. Relationships between ABO blood groups and risk of benign or malignant diseases have been observed and in this study, we aimed to investigate whether they might affect prognosis and response to chemoradiotherapy in patients with local advanced non-small cell lung cancer (NSCLC). Materials and Methods: Eighty-one patients with non-metastatic local advanced NSCLC were included in the study. ABO blood groups were A in 45 (55.6%), B in 7 (8.6%), AB in 8 (9.9%), and O in 21 (25.9%) patients. The patients were also divided two groups according to blood group A (45 patients) and non-A (B, AB and O; 36 patients). Response to chemoradiotherapy was complete remission in 10 (12.3%), disease regression in 42 (51.9%), stable disease in 12 (14.8%), and disease progression in 17 (21.0%) patients. Results: There was no significant difference among ABO blood group categories or between patients with A blood group and those with non-A blood group in terms of responses to chemoradiotherapy (p>0.05). There were also no significant differences regarding overall and disease-free survival rates. Conclusion: The ABO blood group system has no significant effect on prognosis and response to chemoradiotherapy in patients with non-metastatic NSCLC.

  • Objective: Rhus verniciflua Stokes (RVS) has anticancer effect confirmed by preclinical studies and historical records. We thus tried to evaluate retrospectively the effect of RVS as a complementary medicine for patients with advanced non-small-cell lung cancer (NSCLC) showing refractory to conventional chemotherapy. Patients and Methods: From June 1, 2006 to June 30, 2007, patients with advanced NSCLC who received both the standardized RVS extract and a standard course of second or more line therapy such as pemetrexed ($Alimta^{(R)}$), erlotinib ($Tarceva^{(R)}$), and gefitinib ($Iressa^{(R)}$) were checked. A total of 13 patients were eligible for the final analysis after fulfilling inclusion/exclusion criteria. Time to progression (TTP) of these patients treated with the standardized RVS extract was checked in the aftercare period. Results: Patients received RVS treatment for a median period of 296 (range 84-698) days. The median TTP was 220.5 (range 36-489) days, and three patients (23.1%) had TTP values of 15 more months. No significant side effects from RVS treatment have been observed. Conclusion: The standardized RVS extract might have synergetic effects by assisting apoptosis in advanced NSCLC with concurrent standard therapy agents, since it prolonged TTP without significant adverse effects. This study suggests that the standardized RVS extract is beneficial to patients with chemotherapy-refractory NSCLC. Further clinical trials and preclinical studies are necessary to determine the efficacy and safety of the standardized RVS extract in NSCLC.

  • In metastatic non-small cell lung cancer (NSCLC), the role of radiotherapy (RT) has been limited to palliation to alleviate the symptoms. However, with the development of advanced RT techniques, recent advances in immuno-oncology therapy targeting programmed death 1 (PD-1) and programmed death ligand 1 (PD-L1) and targeted agents for epidermal growth factor receptor (EGFR) mutation or anaplastic lymphoma kinase (ALK) translocation allowed new roles of RT in these patients. Within this metastatic population, there is a subset of patients with a limited number of sites of metastatic disease, termed as oligometastasis that can achieve long-term survival from aggressive local management. There is no consensus on the definition of oligometastasis; however, most clinical trials define oligometastasis as having 3 to 5 metastatic lesions. Recent phase II randomized clinical trials have shown that ablative RT, including stereotactic ablative body radiotherapy (SABR) and hypofractionated RT, to primary and metastatic sites improved progression-free survival (PFS) and overall survival (OS) in patients with oligometastatic NSCLC. The PEMBRO-RT study, a randomized phase II study comparing SABR prior to pembrolizumab therapy and pembrolizumab therapy alone, revealed that the addition of SABR improved the overall response, PFS, and OS in patients with advanced NSCLC. The efficacy of RT in oligometastatic lung cancer has only been studied in phase II studies; therefore, large-scale phase III studies are needed to confirm the benefit of local ablative RT in patients with oligometastatic NSCLC. Local intensified RT to primary and metastatic lesions is expected to become an important treatment paradigm in the near future in patients with metastatic lung cancer.

  • Delphinidin is a major anthocyanidin compound found in various vegetables and fruits. It has anti-oxidant, anti-inflammatory, and various other biological activities. In this study we demonstrated the anti-cancer activity of delphinidin, which was related to autophagy, in radiation-exposed non-small cell lung cancer (NSCLC). Radiosensitising effects were assessed in vitro by treating cells with a subcytotoxic dose of delphinidin (5 μM) before exposure to γ-ionising radiation (IR). We found that treatment with delphinidin or IR induced NSCLC cell death in vitro; however the combination of delphinidin pre-treatment and IR was more effective than either agent alone, yielding a radiation enhancement ratio of 1.54 at the 50% lethal dose. Moreover, combined treatment with delphinidin and IR, enhanced apoptotic cell death, suppressed the mTOR pathway, and activated the JNK/MAPK pathway. Delphinidin inhibited the phosphorylation of PI3K, AKT, and mTOR, and increased the expression of autophagy-induced cell death associated-protein in radiation-exposed NSCLC cells. In addition, JNK phosphorylation was upregulated by delphinidin pre-treatment in radiation-exposed NSCLC cells. Collectively, these results show that delphinidin acts as a radiation-sensitizing agent through autophagy induction and JNK/MAPK pathway activation, thus enhancing apoptotic cell death in NSCLC cells.

  • The burden of lung cancer in terms of mortality is the highest among all types of cancers globally. The present study aimed to evaluate lifestyle related habits, clinico-pathological profile and treatment details of lung cancer patients who were registered at Malabar Cancer Centre (MCC), Kerala, during the calendar year 2010. A retrospective evaluation was made from medical records to gather data from 281 registered lung cancer cases in 241 males and 40 females, with a male to female ratio of 6.03: 1. Approximately 89% of the cases were above 50 years of age. Among males about 91% of the cases were smokers and 62% of them had a chronic smoking habit. Adenocarcinomas, squamous cell carcinomas, non-small cell carcinomas and small cell cancers accounted for 10.7, 13.9, 17.0 and 5.7% respectively. Out of 281 cases around 67% were diagnosed with distant metastasis and the remainder had regional lymph node involvement. However, no statistically significant difference was observed for secondary site of tumor according to gender. As majority of the cases reported at MCC were in an advanced stage of the disease, histology of the secondary site from supraclavicular lymph nodes or liver was taken for diagnosis. Initiation of population based screening for early detection of cancer, and primary and secondary prevention strategies for reducing the prevalence of tobacco consumption are high priorities to reduce the lung cancer burden in Kerala.

  • 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.

  • Objective : This study reports one case of a patient diagnosed with squamous cell carcinoma of the lung cancer with bone metastasis. Methods : A 56-year old male patient was diagnosed as squamous cell lung cancer in 1997 and received chemotherapy. The chemotherapy stopped after one cycle because of toxicity and the lung abscess. After four months from the diagnosis, rib metastasis was found and received the radiation therapy for two weeks. After the treatment, adverse effects such as nausea and anorexia appeared. The patient visited K. Korean Medicine Hospital and started the treatment with the allergen removed Rhus verniciflua stokes (aRVS) since December, 1997. Results and Conclusion : During treatment, the patient's quality of life had improved, and he had survived for 14 years after the administration of aRVS. This case suggests that aRVS can be an alternative treatment for the advanced NSCLC patients with bone metastasis.

  • Background: Hepatitis B virus (HBV) infection has been reported to be associated with inferior prognosis in hepatocellular and pancreatic carcinoma cases, but has not been studied with respect to non small cell lung cancer (NSCLC). The purpose of this study was to investigate the prognostic significance of HBV infection in advanced NSCLC patients. Materials and Methods: A retrospective cohort of 445 advanced NSCLC patients was recruited at our hospital from January 1, 2003 until August 30, 2014. Serum HBV markers were tested by enzyme-linked immunosorbent assay. COX proportional hazards analysis was used to evaluate associations of HBV infection with overall survival (OS). Results: Of 445 patients who were qualified for the study, 68 patients were positive for HBsAg, also considered as HBV infection. Patients in HBsAg negative group were found to have better OS (12.6 months [12.2-12.9]) than those in HBsAg positive group (11.30 months [10.8-11.9]; p=0.001). Furthermore, COX multivariate analysis identified HBV infection as an independent prognostic factor for OS (HR 0.740 [0.560, 0.978], p=0.034). Conclusions: Our study found that HBsAg-positive status was an independent prognostic factor for OS in patients with advanced NSCLC. Future prospective studies are required to confirm our findings.

  • The 14-3-3 protein has been shown to be involved in the cancer process. However, there is no understanding of the relationship between 14-3-$3{\gamma}$ (14-3-3 gamma) expression and prognosis in advanced non-small cell lung cancer. In this study, we therefore investigated the association between protein levels by immunohistochemistry and clinicopathological features of advanced NSCLC patients. Survival curves were estimated using the Kaplan-Meier method and tested by log-rank. Multivariate analysis was conducted with the Cox's regression model to determine independence of factors. p values less than 0.05 were considered significant. A total 153 patients were studied, with 54.3% being stage III and 45.8% stage IV. Fifty-one cases (33.3%) were squamous cell carcinomas, and 98 cases (64.1%) were adenocarcinomas. High 14-3-$3{\gamma}$ expression was seen in 59.5% and significantly correlated with lymph node metastasis (p=0.010) and distant metastasis (p=0.017). On Kaplan-Meier analysis, high 14-3-$3{\gamma}$ expression was associated with poorer survival with a marginal trend toward significance (p=0.055). On multivariate analysis, age, treatment, and 14-3-$3{\gamma}$ expression proved to be independent prognostic parameters. In vitro experiments indicated that 14-3-$3{\gamma}$ overexpression also played a potential role in cancer invasion. In conclusion, our data suggest that 14-3-$3{\gamma}$ overexpression is associated with invasion and a poor prognosis. Therefore, 14-3-$3{\gamma}$ may be a potential prognostic marker of advanced non-small cell lung cancer.
