목적 : 국소적으로 진행된 III, IV기 두경부종양의 방사선치료시 항암화학요법을 병행할 경우 방사선에 대한 민감도를 증가시켜 치료효과를 향상시키는 것으로 알려져 있다. 따라서 본 연구는 방사선-항암화학 병용요법이 국소제어율 및 생존율에 미치는 영향을 알아보기 위하여 방사선 단독치료군의 치료결과와 후향적으로 비교분석하였다. 대상 및 방법 : 1983년 11월부터 1994년 3월까지 인제대학교부속 백병원에서 두경부종양으로 진단받고, 추적관찰이 가능했던 III, IV기의 편평상피세포종양 환자 31명(I군: 방사선 단독치료 16명, II군: 방사선-항암화학 병용요법 15명)을 데상으로 하였다. 남녀 비는 I, II군에서 각각 12:4, 15:0 이었고 연령분포는 각각 17-74세(중앙값 64세), 34-71세(중앙값 54세)였다. 병기별 분포는 III기가 각각 5명, 3명, IV기가 11명, 12명이었다 방사선치료는 4MV 선형가속기(LINAC)를 사용하였고 총 방사선 조사선량은 I군 50-77.6Gy(중앙값 70.2Gey), II군 50-75.6Gy(중앙값 70Gy)이었다. 항암화학요법은 cisplatin + 5-FU (7명), methotrexate + leucovorin + 5-FU + cisplatin (혹은 carboplatin) (2명), 방사선민감제로서 clsplatin (6명)이 사용되었다. 결과 : 총 추적관찰기간은 4-134개월(중앙값 16개월)이었다 전체관해율은 I군 $66.6\%$(완전관해 $53.3\%$, 부분관해 $13.3\%$), 11군 $93.3\%$(완전관해 $60\%$, 부분관해 $33.3\%$)였고, 완전관해된 환자에서 2년 종양제어율은 각각 $50\%$, $40\%$이었다. 국소실패율은 I군과 II군에서 각각 $71.5\%$, $72.7\%$이었고, 원격전이율은 $14.4\%$와 $9.1\%$였다. 5년 생존율은 전체 환자에서 $21.5\%$, I군과 II군에서 $23.4\%$, $23.5\%$로 두 군간의 생존율의 차이는 통계학적으로 유의하지 않았다(P>0.05). 3년 무병생존율 역시 $44.5\%$와 $40\%$로 통계학적으로 유의한 차이를 보이지 않았다(P>0.05). 치료에 따른 급성 부작용은 피부독성이 I군 7/16명(RTOG/EORTC 등급 1; 5명, 2; 1명, 3: 1명), II군 5/15명(등급 2: 1명, 3: 4명, 4: 1명), 식도염 및 인두염이 각각 14/16명(등급 1: 7명, 2; 6명, 3이상 1명), 6/15명(등급 2: 1명, 3: 1명), 구강점막염은 각각 6/15명(등급 1: 1명, 2: 2명, 3; 2명, 4: 1명), 9/15명(등급 2: 4명, 4; 5명)으로 두 군간의 차이는 없었으나, 혈액학적 독성은 II군에서만 8/15($53.3\%$)가 관찰되었다. 결론 : 본 연구에서는 방사선-항암화학 병용요법군이 방사선 단독치료군에 비해 종양의 전체관해율은 높았으나, 5년 생존율 및 3년 무병 생존율에서는 두 군간에 통계학적으로 유의한 차이가 없었다(p>0.05). 그러나, 본 연구는 대상환자의 숫자가 제한되어 있어 항암화학요법의 역할을 규명하기 위해서는 앞으로 더 많은 환자를 대상으로 하여 오랜 기간의 추적관찰이 필요하리라 생각된다.

Purpose: To determine failure patterns and survival outcomes of T4N0-1 non-small cell lung cancer (NSCLC) treated with definitive radiotherapy. Materials and Methods: Ninety-five patients with T4N0-1 NSCLC who received definitive radiotherapy with or without chemotherapy from May 2003 to October 2014 were retrospectively reviewed. The standard radiotherapy scheme was 66 Gy in 30 fractions. The main concurrent chemotherapy regimen was $50mg/m^2$ weekly paclitaxel combined with $20mg/m^2$ cisplatin or AUC 2 carboplatin. The primary outcome was overall survival (OS). Secondary outcomes were failure patterns and toxicities. Results: The median age was 64 years (range, 34 to 90 years). Eighty-eight percent of patients (n = 84) had an Eastern Cooperative Oncology Group performance status of 0-1, and 42% (n = 40) experienced pretreatment weight loss. Sixty percent of patients (n = 57) had no metastatic regional lymph nodes. The median radiation dose was EQD2 67.1 Gy (range, 56.9 to 83.3 Gy). Seventy-one patients (75%) were treated with concurrent chemotherapy; of these, 13 were also administered neoadjuvant chemotherapy. At a median follow-up of 21 months (range, 1 to 102 months), 3-year OS was 44%. The 3-year cumulative incidences of local recurrence and distant recurrence were 48.8% and 36.3%, respectively. Pretreatment weight loss and combined chemotherapy were significant factors for OS. Acute esophagitis over grade 3 occurred in three patients and grade 3 chronic esophagitis occurred in one patient. There was no grade 3-4 radiation pneumonitis. Conclusion: Definitive radiotherapy for T4N0-1 NSCLC results in favorable survival with acceptable toxicity rates. Local recurrence is the major recurrence pattern. Intensity modulated radiotherapy and radio-sensitizing agents would be needed to improve local tumor control.

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: High-dose methotrexate (HD-MTX) is recognized as an efficient component of therapy against pediatric osteosarcoma in combination with other drugs such as cisplatin (CDP), carboplatin (CBDCA), doxorubicin (ADM), etoposide (VP-16) and ifosfamide (IFO). Objectives: To demonstrate the feasibility and effectiveness of the HD-MTX/CDP/DOX/VP-16/IFO [MTX(+)] protocol comparable to CDP/ADM/CBDCA/IFO [MTX(-)] for treating childhood osteosarcoma at Ramathibodi Hospital (1999-2014). Materials and Methods: A retrospective analysis was conducted of osteosarcoma patients aged less than 18 years treated with two chemotherapeutic regimens between 1999 and 2014. A total of 45 patients received the MTX(-) and 21 the MTX(+) protocol. Results: Overall limb-salvage and amputation rate were 12.9% and 77.7%, respectively. Kaplan-Meier analysis results for 3-year disease free survival (DFS) and overall survival (OS) regardless of treatment regimens were $43.4{\pm}6.0%$ and $53.2{\pm}6.1%$ respectively. The 3-year DFS and OS were improved significantly with the MTX(+) protocol compared to MTX(-) protocol (p=0.010 and p=0.009, log rank test) [$69.8{\pm}10.5%$, $79.8{\pm}9.1%$ for MTX(+) and $31.1{\pm}6.9%$, $42.2{\pm}7.4%$ for MTX(-) protocol, respectively]. Patients with metastatic osteosarcoma treated with the MTX(+) protocol had statistically significant higher 3-year DFS and OS than those treated with the MTX(-) protocol ($66.7{\pm}13.6%$ and $15.0{\pm}8.0%$ for 3-year DFS, p=0.010, $73.3{\pm}13.2%$ and $20{\pm}8.9%$ for 3-year OS, p=0.006, respectively). The independent risk factors for having inferior 3-year DFS and OS were poor histological response (tumor necrosis <90%) and treatment with the MTX(-) protocol. The multivariate analysis identified only the treatment with the MTX(-) protocol as an independent predictor of inferior OS with a hazard ratio (HR) of 3.53 (95% confidence interval of 1.2-10.41, p=0.022). Conclusions: Our study demonstrated the tolerability, feasibility and efficacy of the HDMTX-based regimen improving the survival rate in pediatric osteosarcoma cases, in line with reports from developed countries.

Purpose: This study aimed to investigate neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) as prognostic factors in patients with locally advanced non-small cell lung cancer (NSCLC) who received concurrent chemoradiotherapy (CCRT). Materials and Methods: We retrospectively analyzed 66 patients with locally advanced NSCLC treated with definitive CCRT. Among these patients, 95% received paclitaxel/carboplatin or docetaxel/cisplatin. The median radiation dose was 66 Gy in 33 fractions. The NLR and PLR before/after CCRT were evaluated. The maximally selected log-rank test was used to obtain the cutoff values related to the overall survival (OS). Results: Patients with high post-CCRT NLR (>3.12) showed worse OS, locoregional progression-free survival (LRPFS), and distant metastasis-free survival (DMFS) than those with low NLR (2-year OS: 25.8% vs. 68.2%, p < 0.001; 2-year LRPFS: 12.9% vs. 33.8%, p = 0.010; 2-year DMFS: 22.6% vs. 38.2%, p = 0.030). Patients with high post-CCRT PLR (>141) showed worse OS and LRPFS than those with low PLR (2-year OS: 37.5% vs. 71.1%, p = 0.004; 2-year LRPFS: 16.5% vs. 40.3%, p = 0.040). Patients with high NLR change (>1.61) showed worse OS and LRPFS than those with low NLR change (2-year OS: 26.0% vs. 59.0%, p < 0.001; 2-year LRPFS: 6.8% vs. 31.8%, p = 0.004). The planning target volume (hazard ration [HR] = 2.05, p = 0.028) and NLR change (HR = 3.17, p = 0.025) were the significant factors for OS in the multivariate analysis. Conclusion: NLR change after CCRT was associated with poor prognosis of survival in patients with locally advanced NSCLC. An elevated NLR after CCRT might be an indicator of an increased treatment failure risk.

The purpose of this study were to illustrate the various medication error types and causes and identified to related drugs to provide basic data for preventing nurses' medication error by analysing 73 cases of AJN 'medication Error' column(1993, Oct -2000, Nov). Nurses' types of medication error were classified into 7 types. The most frequent error types are wrong medication$(21.9\%)$ and the wrong dose$(21.9\%)$ together. The others are wrong $time(4.1\%)$, $omission(2.7\%)$, mechanical $error(2.7\%)$, incorrect IV $rate(1.4\%)$. wrong route $administration(1.4\%)$ in order. Nurses' causes of medication error were 9 kinds.
