Objectives : To evaluate the long-term survival effects of traditional Korean medicine (TKM) on refractory metastatic lung cancer and small cell lung cancer (SCLC), which have historically poor survival rates. Methods : A retrospective study was conducted using the medical records of two patients in Daejeon University hospital. The first patient, with SCLC, was treated from January 2000 to December 2009 and the other, with metastatic pulmonary cancer from primary hepatocellular carcinoma (HCC), was treated from September 2004 to February 2014. The patients were treated with herbal medicines at one-month intervals. During hospitalization, acupuncture and indirect moxibustion were performed concurrent with the administration of Western therapy. Treatment efficacy was assessed monthly using chest radiography, chest computed tomography, and laboratory examination data, and by measuring patient performance status. Results : Both patients exhibited a stable disease course for more than 9 years after the initial diagnosis of intractable lung cancer, suggesting that their disease status was controlled by TKM. Conclusions : We suggest that a combination of TKM with conventional Western therapy for refractory lung cancer patients is effective in controlling various symptoms related to lung cancer and improving quality of life, and may potentially prolong overall survival.

This study was carried out to investigate the mutagenic, antimutagenic, cytotoxicity and antitumor effect of Codonopsis lanceolata (CL). CL was extracted with 70% ethanol and then further fractionated to hexane, chloroform, ethyl acetate, butanol and water. Antimutagenic, cytotoxicity and antitumor effects of CL extracts were measured by using Ames test, SRB method, and the tumor growth inhibition test. CL extracts did not show any mutagenicity in the Ames test; however, 70% ethanol extracts and its fractions had strong antimutagenic effects against mutation induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and 4-nitroquinoline-1-oxide (4NQO). The ethyl acetate fraction of CL (200 ${\mu}g$/plate) showed approximately 72.1% inhibitory effect on the mutagenesis induced by 4NQO against TA98 strain, whereas 69.6% and 67.0% inhibitions were observed on the mutagenesis induced by MNNG and 4NQO against TA100 strain. In anticancer effects, the cytotoxicity of CL extract and its fractions against cancer cell lines including human cervical adenocarcinoma (HeLa), human hepatocellular carcinoma (HepG2), human breast adenocarcinoma (MCF-7), human lung carcinoma (A549) and transformed primary human embryo kidney (293) were investigated. The treatment of 1 mg/mL CL ethyl acetate fraction had the highest cytotoxicity of 74.5%, 70.7% and 80.3% against HeLa, MCF-7 and A549 cells, respectively. In contrast, the extract and its fractions showed only 2$\sim$31% cytotoxicity for a normal human kidney cell line (293). In vivo anticancer effect of CL extract was tested using Balb/c mice transplanted sarcoma-180 cells. CL ethyl acetate fraction showed the highest inhibition rate of 56.4% at the 50 mg/kg concentration.

Purpose: Accurate evaluation of cervical lymph node (LN) metastasis of head and neck squamous cell canter (SCC) is important to treatment planning. We evaluated the diagnostic accuracy of F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for the detection of cervical LN metastasis of head and neck SCC and performed a retrospective comparison with CT/MRI findings. Materials & Methods: Seventeen patients with pathologically proven head and neck SCC underwent F-18 FDG PET/CT and CT/MRI within 4 week before surgery. We recorded lymph node metastases according to the neck level system of imaging-based nodal classification. F-18 FDG PET/CT images were analyzed visually for assessment of regional tracer uptake in LN. We analyzed the differences in sensitivity and specificity between F-18 FDG PET/CT and CT/MRI using the Chi-square test. Results: Among the 17 patients, a total of 123 LN levels were dissected, 29 of which showed metastatic involvement. The sensitivity and specificity of F-18 FDG PET/CT for detecting cervical LN metastasis on a level-by-level basis were 69% (20/29) and 99% (93/94). The sensitivity and specificity of CT/MRI were 62% (18/29) and 96% (90/94). There was no significant difference in diagnostic accuracy between F-18 FDG PET/CT and CT/MRI. Interestingly, F-18 FDG PET/CT detected double primary tumor (hepatocellular carcinoma) and rib metastasis, respectively. Conclusion: There was not statistically significant difference of diagnostic accuracy between F-18 FDG PET/CT and CT/MRI for the detection of cervical LN metastasis of head and neck SCC. The low sensitivity of F-18 FDG PET/CT was due to limited resolution for small metastatic deposits.
