Background: Maspin (mammary serine protease inhibitor) is a member of the serpin superfamily. A few studies have examined the role of maspin in tumor suppression of non-small cell lung cancer (NSCLC); however, its role in the development and progression of NSCLC still remains controversial. We evaluated the immunohistochemical expression of maspin in order to elucidate its clinical significance in NSCLC. Methods: We analyzed 145 patients with pathologically confirmed NSCLC, including 66 cases of squamous cell carcinomas (SCCs) and 79 cases of adenocarcinomas (ADCs). We performed a immuno-histochemical stain with maspin and PCNA (proliferating cell nuclear antigen) using tissue microarray blocks. Results: There were 108 men and 37 women in the study population. The mean age of patients in the study was 63.7 years (range, 40.0~82.0; median, 65.0). The proportion of maspin expression was significantly higher in SCCs (52/66, 78.8%; p<0.01) than in ADCs (17/79, 21.5%; p<0.01). Maspin expression was not associated with PCNA (p=0.828), lymph node involvement (p=0.483), or tumor stage (p=0.216), but showed correlation with well-to-moderate tumor differentiation (p=0.012). There was no observed correlation between maspin expression and survival with NSCLC (p=0.218). Conclusion: The present study suggests that maspin expression was significantly higher in SCCs than in ADCs and was associated with low histological grade. However, maspin expression was not an independent factor to predict a prognosis in NSCLC.

This report documents a case in which the administration of an herbal product, an extract of the lacquer tree, Rhus verniciflua Stokes, as sequential and concurrent treatment with chemotherapy was associated with a long term survival and good quality of life in a patient with metastatic non-small cell lung cancer(NSCLC). A 51-year-old Korean female was referred to the $M{\cdot}{\mu}$ Integrative Cancer Center, East-West Neo Medical centrer, Kyung Hee University for stage IV, metastatic NSCLC. She was treated with aRVS alone for 19 months and then received 1st line paclitaxel/carboplatin combined with aRVS, 2nd line gefitinib, and 3rd line pemetrexed. The number of cycles of pemetrexed administered was seventeen. aRVS was restarted as the 13th pemetrexed was administered. Pemetrexed with aRVS is currently ongoing. This patient has been alive for 41 months, and has been keeping a good performance status so far. We suggest aRVS as sequential and concurrent treatment with chemotherapy is an effective alternative treatment strategy.

Background: Recent studies have demonstrated that the epidermal growth factor receptor (EGFR) genotype is the most important predictive marker to EGFR-tyrosine kinase inhibitors (TKIs) and first-line gefitinib treatment will be approved in the near future for use in non-small cell lung cancer (NSCLC) patients with the EGFR mutation. Direct sequencing is known to be the standard for detecting EGFR mutations; however, it has limited sensitivity. Peptide nucleic acids (PNA)-mediated PCR clamping method is a newly introduced method for analyzing EGFR mutations with increased sensitivity and stability. Methods: A total of 71 NSCLC patients were analyzed for EGFR mutations using the PNA-mediated PCR clamping technique. Sixty-nine patients were analyzed for clinicopathologic correlation with EGFR genotype; 2 patients with indeterminate results were excluded. In order to determine EGFR-TKI drug response, 57 patients (42 gefitinib, 15 erlotinib) were included in the analysis. Results: The EGFR mutation rate was 47.8%. Being female, a non-smoker, and having adenocarcinoma were favorable clinicopathologic factors, as expected. However, more than a few smokers (33.3%), male (28.1%), and patients with non-adenocarcinoma (28.6%) had the EGFR mutation. Having a combination of favorable clinicopathologic factors did not increase the EGFR mutation rate significantly. Drug response to EGFR-TKIs showed significant differences depending on the EGFR genotype; ORR was 14.3% for wild type vs 69.0% for mutant type; DCR is 28.6% for wild type vs 96.6% for mutant type. The median EGFR-TKI treatment duration is 7.6 months for mutant type group and 1.4 months for wild type group. Conclusion: EGFR genotype determined using the PNA-mediated PCR clamping method is significantly correlated with the clinical EGFR-TKI responses and PNA-mediated PCR.

Objectives : Epidermal growth factor receptor-inhibitors have demonstrated improved overall survival in patients with non-small cell lung cancer, but their use is associated with dermatologic adverse reactions that often require symptomatic treatment. Methods : A 44-year-old woman, who started the chemotherapy of Iressa$^{(R)}$ on August 2010, developed cutaneous symptoms such as papulopustular rash, dry skin, and pruritus on her face and scalp after taking Iressa$^{(R)}$ for four weeks. The patient visited our clinic with such symptoms on March 2011 and underwent herebal remedy targeted to alleviate the skin reactions. The severity of dermatologic symptoms was evaluated with the numeric rating scale and the Common Terminology Criteria for Adverse Events version 4.0. Results : Noticeable changes on the skin lesion were observed after the two months of treatment, without any dose modification of the Iressa$^{(R)}$. The cutaneous symptoms as papulopustular rash, dry skin and pruritus were improved and there was no adverse event induced by the treatment with herbal medicine. Conclusions : This case report suggests that the treatment with a herbal medicine, Samultang-gagambang be considered as a useful treatment to relieve EGFR-inhibitor induced dermatologic adverse reactions.

From 1979 to 1982, 80 patients with unresectable non-small-cell lung cancer without metastasis were treated with high-dose radiotherapy to the primary and to regional lymph nodes with or without supraclavicular lymphatics in the Department of Therapeutic Radiology, Seoul National University Hospital. Of these, 56 patients$(70\%)$ were completely evaluable, and 59 patients$(74\%)$ had squamous cell carcinoma, 13a large cell undifferentiated carcinoma and 831 adenocarcinoma. 21 patients$(26\%)$ had Stage II and 59 patients$(74\%)$ had Stage III. The complete and partial response rate in the high-dose$(\approx\;6,000\;rad)$ radiotherapy was $70\%\;with\;19\%$ complete response. 69 patients$(86\%)$ failed in the treatment, by the failure pattern, $64\%$ had local failure alone, $35\%$ had local failure and distant metastasis and $1\%$ had distant metastasis alone. The failure rate in the thorax were $76\%$ in squamous cell carcinoma, $40\%$in adenocarcinoma and $20\%$ in large cell undifferentiated carcinoma Preliminary result shows that actuarial survival at 1, 2 and 3 years were $56\%,\;26\%\;and\;20\%$ in overall patients and $64\%,\;37\%\;and\;21\%\;in\;Stage\;II\;and\;54\%1,\;21\%\;and\;18\%$ in Stage III, respectively. Overall median survival was 14 months; 17 months in Stage II and 13 months in Stage m. 8 patients$(10\%)$ have lived a minimum of 2 years with no evidence of disease. There was no fatal complication confirmed to be induced by radiotherapy, so definitive high-dose radiotherapy was tolerated well without major problems and resulted in good local control and survival.

The syndrome of inappropriate secretion of the antidiuretic hormone (SIADH) is a well recognized paraneoplastic phenomenon related to impaired water excretion, and can result in dilutional hyponatremia as well as central nervous system symptoms. It is characterized by a decrease in plasma osmolarity with inappropriately concentrated urine. The causes of SIADH are associated with pulmonary and endocrine disorders, central nervous system diseases, and malignancies, including lung cancer. The other causes of SIADH include some drugs, particularly chemotherapy agents. Anticancer drugs, such as cisplatin, vincristine, and cyclophosphamide are well known causes of SIADH but the mechanisms are unclear. Recently, we encountered a patient with advanced non-small cell lung cancer who suffered from general weakness and altered mentality after an intravenous carboplatin and gemcitabine combination.

Objectives: We report a case of traditional Korean medicine (TKM) treatment for skin side effects after taking afatinib (Giotrif$^{(R)}$). Methods: A 62-year-old female who was diagnosed with non-small cell lung cancer stage 4 (T4N2M1b) and was on treatment with afatinib (29.56 mg/day for 4 months) complained of skin toxicity as a side effect. For 16 admission days, the patient was treated with acupuncture, moxibustion, and herbal medicine (oral decoction and external ointment). Results: Improvement of skin toxicity was measured by a numeric rating scale. In addition, Quality of life (QOL) was measured using EORTC Quality of Life Questionnaire, Core 30 (EORTC QLQ-C30) and EORTC Quality of Life Questionnaire, 13-item lung cancer-specific module (EORTC QLQ-LC13) Developed by the European Organization for Research and Treatment of Cancer (EORTC). Tumor size and carcinoembryonic antigen (CEA) were also examined during follow up. Conclusions: After a combined TKM treatment, skin toxicity symptoms and quality of life scales were significantly improved with no side effects. The tumor size was not changed on computed tomography during follow-up period. CEA levels were decreased.

Several studies showed that the survival rate of stage IIIB disease with malignant pleural effusion is worse than stage IIIB disease without malignant effusion. But, malignant pleural effusion was considered T4. To analyze changes the survival time for malignant pleural effusion, in the seventh revision of TNM classification for lung cancer. The records of all patients had to have either a histological or cytological diagnosis of non-small cell lung cancer (NSCLC), who were admitted to Wonkwang university hospital between January 2004 and December 2006 were reviewed retrospectively. We evaluated the survival time of 187 patients with advanced lung cancer with and without malignant pleural effusion. This included the pleural effusion or nodule M1 a (pleural dissemination, currently classified as T4), nodule(s) in the other lung M1 a (contralateral lung nodule, currently classified as M1), nodule(s) with the same lobe as the primary tumor T3 (currently classified as T4), other T4 factors T4 (T4 MO anyN), and extrathoracic sites of disease M1b (distant metastasis, currently classified M1). Among the 187 patients, T4anyNMO was 57 patients in the current TNM classification. In the next edition of the TNM classification, T4MOanyN-T4 (excluding same lobe nodules) was 12 patients, pleural dissemiantion-M1a was 45 patients, contralateral lung nodule(s)-M1a was 7 patients, and metastatic disease-M1b was 55 patients. We compared the survival time for these groups. Survival time was 11 months, 8 months, 11 months, and 4 months. The survival time of malignant pleural effusion was shorter than other T4 factors without pleural effusion. But, there was no remarkable difference in statistics due to small cases (p=0.23). We strongly suggest that malignant pleural effusion in advanced NSCLC will be categorized with metastatic disease.

Background: Acyl protein thioesterase-1 (APT1) is a cytosolic protein that may function in the depalmitoylation of numerous proteins, including the Ras family. However, the clinical role of depalmitoyl thioesterase in human cancer is not known. We evaluated the APT1 expression in lung cancer tissue and its clinicopathological findings according APT1 expression pattern. Methods: APT1 expression was examined by immunohistochemistry in the tumor tissue from 79 patients, who had undergone curative surgical removal of the primary lesion; all patients had been diagnosed with stage I non-small cell lung cancer between 1993 and 2004, at Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul, Korea. Results: The APT1 expression was seen in 50 out of 79 (63.3%) cases. The positive APT1 expression was significantly related with histologic subtype and T stage, but was not influenced by differentiation. The positive APT1 expression was not significantly related to patient age, gender, or smoking history. The median follow-up duration was 10.0 years; the 5-year survival rate was 71.0%. The positive APT1 expression group showed significantly worse overall survival and worse disease-free survival without statistical significance. Conclusion: We conclude that positive APT1 expression in stage I lung cancer after surgery is closely associated with overall survival. To evaluate APT1 as a prognostic marker in lung cancer, comprehensive studies on advanced stage cases are needed.

Background: Pemetrexed, a multi-targeted antifolate has been used as a second line treatment against non-small cell lung cancer (NSCLC). We aimed to clarify the efficacy and survival according to line of treatment, histologic type, and expression of thymidylate synthase (TS). Methods: Ninety-eight patients were treated with pemetrexed as a second line treatment (n=43) or as an additional course of treatment (n=55). TS expression was studied with immunohistochemistry and graded as 0 to 3 based on the extent of expression. Results: The response rate (RR) in 98 subjects was 10.2% and the disease control rate (DCR=PR+SD) was 30.6%. RR and DCR were 12.7% and 32.7% in non-squamous cell carcinoma (NSQC) compared to 7.0% and 27.9% in squamous cell carcinoma (SQC) (p>.05). No significant differences in RR and DCR were observed between a second line group (4.7%, 20.9%) and a further line group (14.5%, 38.2%). A similar trend was observed in the 88 response evaluable subjects. TS was expressed in 28.6% (grade 1), 24.5% (grade 2) and 7.1% (grade 3), respectively, and it was not expressed in 39.8% of subjects. TS expression rate was significantly higher in the SQC (72.1%) compared to NSQC (50.9%, p=0.033). However, the efficacy of pemetrexed was not significantly different by the extent of TS expression. Conclusion: Pemetrexed showed efficacy, not only in a second-line setting, but also in further lines of treatment for NSCLC. The efficacy of pemetrexed tended to be higher in patients with NSQC compared to SQC. TS expression rate was significantly higher in SQC compared to NSQC.
