Objective: To explore improved treatment by retrospectively comparing survival time of gemcitabine-based concurrent chemoradiotherapy (GemRT) versus chemotherapy (Gem) alone in patients with locally advanced pancreatic cancer (LAPC). Methods: From January 2005 to June 2010, 56 patients with LAPC from Subei People's Hospital were treated either with Gem (n=21) or GemRT (n=35). Gem consisted of 4-6 cycles gemcitabine alone (1000 mg/m2 on Days 1, 8, 15, 28-day a cycle). GemRT consisted of 50.4Gy/28F radiotherapy with concurrent 2 cycles of gemcitabine (1000 $mg/m^2$ on days of radiation 1, 8, 15, 21-day a cycle). Radiation was delivered to the gross tumor volume plus 1-1.5 cm by use of a three-dimensional conformal technique. The follow-up time was calculated from the time of diagnosis to the date of death or last contact. Kaplan-Meier methodology wes used to evaluate survival. Results: Patient characteristics were not significantly different between treatment groups. The disease control rate and the objective response rate of GemRT versus Gem was 97.1% vs 71.4%, 74.3% vs 38.1%. The overall survival (OS) was significantly better for GemRT compared to Gem (median 13 months versus 8 months; 51.4% versus 14.3% at 1 year, respectively). Conclusion: Radiation therapy at 50.4Gy with 2 concurrent cycles of gemcitabine results in favorable rates of OS. Concurrent chemoradiotherapy should be the first choice for patients with LAPC.

Purpose: To evaluate the clinical outcomes of patients who underwent radiation therapy with or without targeted molecular therapy for the treatment of spinal metastasis from renal cell carcinoma (RCC). Materials and Methods: A total of 28 spinal metastatic lesions from RCC patients treated with radiotherapy between June 2009 and June 2015 were retrospectively reviewed. Thirteen lesions were treated concurrently with targeted molecular therapy (concurrent group) and 15 lesions were not (nonconcurrent group). Local control was defined as lack of radiographically evident local progression and neurological deterioration. Results: At a median follow-up of 11 months (range, 2 to 58 months), the 1-year local progression-free rate (LPFR) was 67.0%. The patients with concurrent targeted molecular therapy showed significantly higher LPFR than those without (p = 0.019). After multivariate analysis, use of concurrent targeted molecular therapy showed a tendency towards improved LPFR (hazard ratio, 0.13; 95% confidence interval, 0.01 to 1.16). There was no difference in the incidence of systemic progression between concurrent and nonconcurrent groups. No grade ${\geq}2$ toxicities were observed during or after radiotherapy. Conclusion: Our study suggests the possibility that concurrent use of targeted molecular therapy during radiotherapy may improve LPFR. Further study with a large population is required to confirm these results.

Aspirin and prednisolone have been used alone or in combination in the treatment of rheumatic diseases. We have investigated the significance of the difference of the anti-inflammatory and antipyretic activities between single and concurrent administration of aspirin and prednisolone in rats by using carrageenan as a phlogistic agent and brewer's yeast as a fever inducing agent. When prednisolone (9mg/kg) and aspirin (24mg/kg) were administered orally alone or in combination, both of the concurrent and single adminstration inhibited highly significantly the swelling of rat paw and the concurrent adminstraiton of aspirin and prednisolone showed the significantly higher inhibitory effects than aspirin single adminstration did, whereas there were not any significant differences between the prednisolone single adminstration and combined adminstration. The combined drug of aspirin and prednisolone marketed in Korea contains 148mg of aspirin and 1.15mg of prednisolone in a tablet. Therefore, we examined the anti-inflammatory and antipyretic activities of aspirin (150mg/kg), prednisolone (1mg/kg) and their combination. In anti-inflammatory effects, both of the concurrent and single administration inhibited higly significantly the swelling of rat paw, and the concurrent adminstration exhibited the significantly higher inhibitory effects than aspirin or prednisolon alone did. In antipyretic effects both of the concurrent and the single adminstration reduced significantly the brewer's yeast-induced fever. The effect of concurrent administration was greater than that of prednisolone single adminstration, whereas the effect of aspirin single adminstration was similar to that of combination. The results suggest that the anti-inflammatory and antipyretic effects are intensified by the concurrent adminstration of aspirin and prednisolone, but the antipyretic effects of enough doses of aspirin (150mg/kg) is comparable to that of the combination preparation.

There are very few case reports of the diagnosis and management of concurrent oral cavity and parapharyngeal space tumors. We present a case involving a 49-year-old female who presented with oral cavity squamous cell carcinoma confirmed by biopsy. Initial diagnostic workup revealed a concurrent parapharyngeal mass. Diagnostic studies and surgical therapy were tailored to account for both pathological entities. The patient was treated with a combination of surgery and adjuvant therapy. The surgical strategy was designed to address both lesions simultaneously. One year post-surgery, the patient had good response to therapy with no evidence of persistent or recurrent disease. This report discusses the outcome and treatment of a rare case of concurrent squamous cell carcinoma with a complicating parapharyngeal space tumor. It explores the diagnostic process, comprehensive workup, and the surgical management.

Objective : The purpose of this study is to analyze Korean patients' characteristics, who were concurrently treated with both Korean herbal medicines and Western chemical medicines using nation-wide database. Method : Using the patients sample data (HIRA-NPS 2018) provided by Health Insurance Review and Assessment Service, a group of patients who co-administered Korean herbal and Western medicines was selected, and their basic characteristics, diagnosis, and prescribed chemical medicines were analyzed. Results : Out of the 1,481,921 sample population, 17,629 patients (1.2%) were selected as a concurrent medication group. Compared to the whole sample, the concurrent medication group was composed of more women (65.8% vs. 51.1%), the more elderly people (65 or older years old) (44.5% vs. 14.6%), and the higher prevalence of chronic diseases (49.1% vs. 22.2%). The most frequent diagnosis treated with Western medicines was mental and behavioral disorders, musculoskeletal and circulatory disorders. Frequently used drugs among concurrent medication group were anti-anxiety drugs, gastric ulcer treatment drugs, and senile diseases treatment drugs. Conclusion : The evidence reported in this study is expected to provide herb-drug interaction researchers with important reference to set the priorities of research topics in the future.

Objectives : In order to observe clinical effects, carboxytherapy and electroacupuncture, we analyzed relation effect and patients' character, and researched correlation among reduction of BFM(Body Fat Mass), WHR(Waist-Hip Ratio) and AC(Arm Circumference). Methods : Among outpatients who had admitted to department of oriental rehabilitation medicine, Dae-Jeon oriental medicine hospital, Dae-Jeon university from January to September, 2008 for obesity treatment and abdominal fat, 44 subjects were chosen and carboxytherapy and electroacupuncture were practiced concurrently. Results : 1. The group under the concurrent practice of carboxytherapy and electroacupuncture showed significant decrease in BFM, BFR(Body Fat Rate), WHR and AC. 2. The group under the concurrent practice of carboxytherapy and electroacupuncture did not show statistical significance but showed decrease in BFM, WHR. The degree of decrease was proportional to that of obesity. 3. As AC decreased, BFM, WHR reduction tended to increase as well in the group under the concurrent practice of carboxytherapy and electroacupuncture. 4. Compared to the group under the sole practice of electroacupuncture, the group under the concurrent practice of carboxytherapy and electroacupuncture showed less change in BFM reduction and greater change in WHR reduction. Conclusions : From the above results, the concurrent practice of carboxytherapy and electroacupuncture had an effect on obesity and reducing abdominal fat, but did not show statistically significant decrease compare to the sole practice of electroacupuncture.

These studies were attempted to investigate the preventive effect of Ganoderma lucidum extract administered concurrently with glutathione on the liver damage induced by carbon tetrachloride ($CCl_4$) in rats. S-GOT and S-GPT activities of all the pre-treatment groups were significantly decreased, as compared with those of the control intoxicated by $CCl_4$. The concurrent administrations of Ganoderma lucidum extract with glutathione (100+100mg/kg, 200+100mg/kg, and 400+100mg/kg, respectively) were more effective than the individual administrations. i.e., Ganaderma lucidtcm extract (100, 200 and 400mg/kg, respectively) and glutathione (100, 200 and 400mg/kg, respectively). On the determination of lipid-peroxidation in liver, the concurrent administrations of Ganoderma lucidum extract with glutathione (100+100mg/kg, and 200+100mg/kg, respectively) significantly reduced the liver TBA values. Although hepatic cellular necrosis and fatty acid deposit were remarkably increased by $CCl_4$ intoxication, the concurrent administration of Ganoderma lucidum extract with glutathione (200+100mg/kg) reduced the pathological changes of parenchymal cell necrosis and fatty changes around centrilobalar area of the control. These findings indicate that the concurrent administrations of Ganoderma lucidum extract with glutathione showed better improvements than the individual administrations of them in all pathological aspects, in particular, against hepatitis and hepatic necrosis due to the cellular necrosis and fatty infiltration.

Background: Many recent results of clinical trials show that pre-operative concurrent chemoradiotherapy and surgical resection could increase the survival of N2 positive stage IIIA non-small cell lung cancer. This study was performed to assess the feasibility, toxicity, and affect rates of concurrent chemoradiotherapy and surgical resection in N2 positive stage IIIA non-small cell lung cancer. Material and Method: Thirty-one patients who underwent preoperative concurrent chemoradiotherapy for N2 positive stage IIIA non-small-cell lung cancer from May 1997 to April 1999 were entered into the study. Mean age was 61 yrs(43∼70 yrs), There were 24 men and 7 women. The confirmation of N2 disease were achieved through mediastinoscopic biopsy(24) and CT scans(7). Induction was achieved by two cycles of cisplatin and etoposide(EP) plus concurrent chest radiotherapy to 45 Gy. Resections were done at 3 weeks after the complection of preoperative concurrent chemoradiotherapy. Resections were performed in 23 patients, excluding 5 refusals and 3 distant metastasis. Result: All patients were compled the thoracic radiotherapy except one who had distant metastasis. Twenty three patients were completed the planned 2 cycles of EP chemotherapy, and 8 patients were received only 1 cycle for severe side effects(6), refusal(1), and distant metastasis(1). There was one postoperative mortality, and the cause of death was ARDS. Three patients who had neutropenic fever and one patient who had radiation pneumonitis were required admission and treatment. Esophagitis was the most common acute side effect, but relatively well-tolerated in most patients. The complection rate of concurrent chemoradiotherapy was 74%, resection rate was 71%, pathologic complete remission rate was 13.6%, and pathologic down-staging rate was 68%. Conclusion: Morbidity related to each treatment was acceptable and many of the patients have benefited down staging of its disease. Further prospective, preferably randomized, clinical trials of larger scale may be warranted to confirm the actual benefit of preoperative concurrent chemoradiotherapy and surgical resection in N2-positive stage IIIA non-small cell lung cancer.

목적 : 국소 진행된 비인강암으로 유도 화학요법 혹은 동시 화학요법 및 방사선 치료를 받은 환자들의 부작용 및 단기 생존율을 비교하기 위하여 본 연구를 시행하였다. 대상 및 방법 : 1989년 10월부터 1998년 5월까지, 비인강암으로 진단받고 유도 화학요법 혹은 동시 화학요법 및 방사선 치료를 받은 62명의 환자들을 대상으로 후향적 분석을 시행하였다. 유도 화학요법군은 50명, 동시 화학요법군은 12명이었다. 나이, 성, 전신 수행능력, 조직학적 유형 등은 양군에서 비교적 고르게 분포하였다. 병기 분포는, 유도 화학요법군의 경우 IIB가 $32\%$, III가 $30\%$, 그리고 IV가 $38\%$였으며, 동시 화학요법군은 각각 50, 33.3, $16.7\%$였다. 양군에서 화학요법 약제는 CF (cisplatin and 5-FU)였고, 약제 투여 방법은 동일하였다. Cisplatin $100\;mg/m^2$을 day 1에, 5-FU $1,000\;mg/m^2$을 day $2\~6$에 각각 정맥투여하였으며 3주 간격으로 반복하였다. 방사선 치료 종료시까지 시행된 화학요법의 횟수는 양군 모두 테$1\~3$회(중앙값 2회)였다. 방사선 치료는 양군 모두 일일선량 $1.8\~2.0\;Gy$를 주 5회 조사하였다. 총 방사선량은, 유도 화학요법군의 경우 $69.4\~86\;Gy$ (중앙 선량 73.4 Gy), 동시 화학요법군은 $69.4\~75.4\;Gy$ (중앙 선량 70.8 Gy)였다. 추적기간은, 유도 화학요법군의 경우 $9\~l16$개월(중앙값 40.5개월), 동시 화학요법군은 $14\~29$개월(중앙값 21개월)이었다. 결과 : 전체 환자에서 2년 생존율은 $78.7\%$였다. 치료 방법별 2년 전체 생존율은, 유도 화학요법군이 $77\%$, 동시 화학요법군은 $87\%$였으며(p>0.05), 2년 무병 생존율은 각각 $56\%$ 와 $81\%$였다(p>0.05). 최종 치료에 대한 완전 관해율은 $75.5\%$와 $91.7\%$로 동시 화학요법군에서 높았으나 통계학적 유의성은 없었다. 방사선 치료시 grade $3\~4$의 혈액학적 독성은 양군에서 차이가 없었고, grade 2의 백혈구 감소가 동시 화학요법군에서 많았다 $(18\%\;vs\;66.7\%)$. Grade $3\~4$의 점막염은 동시 화학요법군에서 많았다$(4.0\%\;vs\;33.3\%)$. 전체적으로 grade $3\~4$의 급성 부작용이 동시 화학요법군에서 빈번하였고$(6.0\%\;vs\;41.7\%,\;p=0.005)$, 부작용으로 사망한 경우는 없었다. 결론 : 국소 진행된 비인강암에서 동시 화학요법을 시행함으로써 치료의 반응율과 2년 무병 생존율이 향상되는 경향을 보였으나, 통계학적 의의는 없었다. 따라서, 좀더 많은 대조군과 장기 추적관찰이 요구된다.
