Ginseng has been used as an herbal medicine, widely used in Asian countries, for long time. Recently, beneficial effects for immune functions of Korean red ginseng (KRG) have been reported in adults. This study was performed to investigate the effects of ginseng on immune functions in children after cessation of chemotherapy or stem cell transplantation for advanced cancer. Thirty patients, who were diagnosed and treated for leukemia and solid cancer at the department of pediatrics and adolescence of the Yeungnam University Hospital from June 2004 to June 2009, were enrolled for the study. The study group consisted of 19 patients who received KRG extract (60 mg/kg/d) for 1 yr and 11 patients who did not receive KRG extract were the control group. Blood samples were collected every 6 mo. Immune assays included circulating lymphocyte subpopulation, serum cytokines (IL-2, IL-10, IL-12, TNF-alpha, and IFN-gamma), and total concentrations of serum IgG, IgA, and IgM subclasses. Age at diagnosis ranged from 2 mo to 15 yr (median 5 yr). Nine patients received stem cell transplantation. The cytokines of the KRG treated group were decreasing more rapidly than that of the control group. Lymphocyte subpopulations (T cell, B cell, NK cell, T4, T8, and T4/T8 ratio) and serum immunoglobulin subclasses (IgG, IgA, and IgM) did not show significant differences between the study and the control groups. This study suggests that KRG extract might have a stabilizing effect on the inflammatory cytokines in children with cancer after chemotherapy.

Background: Cancer is a major cause of mortality in developing countries and correct and valid information about the epidemiology of this disease is the first step in the planning of health care in each region. The aim of this study was to determine the relative frequency, mean age and sex ratio of the most 10 common non-skin cancers in the world and Iran, among patients referred to an oncology clinic. Materials and Methods: This descriptive study was conducted in Mashhad, north east of Iran. The data obtained from the records of patients referred to the private oncology center between the years of 1985-2012". According to the latest report of GLOBOCAN study commonest malignancies included were lung, breast, colorectal, prostate, stomach, liver, cervix, esophageal, bladder cancers and Non-Hodgkin lymphoma. Results: A total of 4,606 cases were analyzed. The mean age was $55.5{\pm}13.8years$ (male: $59.5{\pm}13.9$, female: $52.6{\pm}12.9$). Overall, breast cancer (1,264 cases, relative frequency of 27.4%) was the most prevalent cancer; however the mean ages of diagnosis were not significantly different between 5-year time period divisions (p=0.290). The most common cancer in men was esophageal cancer (26.3%).The lowest mean age was related to women diagnosed with breast cancer ($48.5{\pm}11.8$) and men with non-Hodgkins lymphoma ($48.4{\pm}17.8$). There were statistically significant differences between the mean age of men and women with gastric (p=0.003) and esophageal cancers (p<0.001). Male to female sex ratios in our study for bladder, lung and stomach cancers were 6.57, 2.60 and 2.50 respectively. Conclusions: The results showed that breast cancer tends to be found in younger female patients and bladder cancer appears more often in men. Screening in target population in addition to early diagnosis may reduce death and disability.

비뇨기암에서의 $^{18}F-FDG$를 이용한 PET-CT 검사는 해부학적 구조 및 $^{18}F-FDG$의 배출 경로로 인해 암 진단에 한계가 있다. 그러한 한계점을 보완 할 수 있는 검사 중 아세트산을 이용한 검사가 진행되고 있으며 비뇨기암 환자를 대상으로 $^{11}C-Acetate$ PET-CT 검사의 임상 적용에 대하여 소개하고자 한다. 현재 본원에서 비뇨기암을 진단 받은 환자 중에 전립선암 환자 10명, 신세포암 환자 10명, 방광암 환자 2명을 총 22명을 임상 연구로 시행하였다. 모든 환자는 $^{18}F-FDG$ PET-CT 검사를 시행하였고, 평균 2주 정도의 기간 후에 $^{11}C-Acetate$ PET-CT 검사를 진행하였다. 검사 장비는 GE사의 D-710 PET-CT 장비를 사용했고, 검사 진행은 $^{11}C-Acetate$ 주사 후 15분 후에 PET-CT 검사를 시작하였고, $^{18}F-FDG$와 $^{11}C-Acetate$영상의 비교 평가는 핵의학과 전문의가 판별했다. 전립선암 환자의 경우 일반적으로 $^{18}F-FDG$의 섭취가 다른 암종에 비해 낮은 특징이 있다. 본원에서 연구된 10명의 환자 중 2명의 환자의 전이된 암이 $^{18}F-FDG$ 보다 $^{11}C-Acetate$의 섭취가 잘 나타났다. 신세포암의 경우 10명의 환자 중 8명의 환자에서 $^{18}F-FDG$ 보다 $^{11}C-Acetate$의 섭취가 확연히 잘 나타났다. 방광암 환자의 경우 방광의 $^{18}F-FDG$ 섭취가 너무 강하고, 이뇨제 사용여부와 환자의 조건이 맞지 않아 임상연구에서 제외하였다. 현재 임상 연구 진행 중인 검사로서 아직은 많은 환자에 대한 검사를 시행하지 못해서 이렇다 할 결과를 말하기에는 시기상조이다. 하지만, 해외에서는 이미 비뇨기암에서의 $^{11}C-Acetate$ PET-CT 검사가 어느 정도 유용하다는 논문이 많이 발표되었고, 본원에서도 현재 연구 진행 중이다. 보다 더 많은 환자에 대한 검사가 이루어진다면, 전립선암 환자에서 Prostatic specific antigen(PSA) 수치와 $^{11}C-Acetate$ PET-CT의 상관관계, 수술 전 환자에서의 조직 검사상의 Gleason sum 수치와의 상관관계, 다른 비뇨기암에서의 $^{18}F-FDG$ PET-CT 검사와 $^{11}C-Acetate$ PET-CT 검사 사이의 특이도, 민감도, 양성예측도, 음성예측도 등의 척도로서의 비교 등의 다양한 주제로서의 논문이 진행 될 수 있을 것이며, 비뇨기암에서의 $^{11}C-Acetate$ PET-CT 검사가 보다 더 활성화 되어 질 것이라 사료된다.

Nodular thyroid disease is a common clinical problem. The problem in clinical practice is to distinguish malignant or potentially malignant tumor from harmless nodules. The cases of thyroid nodule surgically managed at Department of General Surgery, Soon Chun Hyang Univ. Hospital during the period Jan. 1985 to July. 1992 were reviewed retrospectively. To assess method of distinguishing malignant from benign lesions of the thyroid gland, we reviewed 162 patients with thyroid nodule. There were 61(37.7%) malignant nodules and 101(62.3%) benign nodules. According to the review, distinguishing the benign from the malignant nodule with history, physical examination, clinical manifestation, and duration of illness was not suggested sufficiently. In ultrasonogram of 73 cases, 57.5% of nodules were solid, 20.6% were cystic, 21.9% were mixed solid and cystic. Of these, 28.5% of the operated solid lesions, 12.5% of the mixed lesions, and only 6.7% of the cystic lesions were malignant. Thyroid scanning of 82 cases revealed cold nodules in 60 patients(73.2%), of which 26 cases were malignant(36.6%) 137 patients underwent fine needle aspiration cytology(FNAC), and these results were as follow: sensitiviey was 70.6%, specificity was 93.0%, false-positive rate was 14.3%, and false-negative rate was 15.8%. 41 patients underwent frozen biopsy, and the results as follow: sensitivity was 80.0%, specificity was 89.7%. Neither scintigraphy nor ultrasonogram has sufficient specificity to distinguish benign from malignant nodule. But FNAC and frozen biopsy have sufficient accuracy to differentiate benign from malignant nodule. In the benign nodules, the most common type of operation was total lobectomy (60.4%). Of the malignant nodules, total thyroidectomy with or without modified radical neck dissection was performed in 30 cases(49.2%). We conclude that the single technique used to determine the differential diagnosis of a thyroid nodule are unrealiable. It is therefore essential to combine all avaiable clinical and laboratory information.

This study was carried out to investigate the anti-cancer effects of Gunbibosinhangam-tang (GBHT I) and Gunbibosinhangam-tang-gamibang (GBHT II, GBHT III) on solid tumor and immune cells. The animals were divided into 4 groups ; Control, no treatment. GBHT I, treatment with GBHT itself. GBHT II, treatment with GBHT increased the quantity of Hedyotis Diffusae twice. GBHT III, treatment with GBHT increased the quantity of Hedyotis Diffusae four times. We investigated the effects of GBHT on proliferation of solid tumor cells (S-180), thymocytes, splenocytes in vitro in order to examine cytotoxicity for S-180 and immuno-stimulating activities. The experiments that is about solid tumor weight and survival rate in tumor bearing mice were performed also. As compared with the control group, treatments with GBHT II and GBHT III suppressed the proliferation of S-180 effectively. Treatments with all experimental groups accelerated the proliferation of thymocytes and splenocytes significantly. In addition, GBHT III was significantly decreased on solid tumor weight and increased on survival rate in tumor bearing mice. Based upon these results, we suggest that GBHT and GBHT-gamibang have both anti-cancer effects for S-180 and immuno-stimulating activities for thymocytes and splenocytes. Therefore, we conclude that GBHT and Hedyotis Diffusae is useful to treat the patients with cancer.

Background: To compare response evaluation criteria in solid tumours (RECIST) and volumetric evaluation (VE) for colorectal cancer with liver-limited metastasis. Patients and Methods: VE of liver metastases was performed by manual contouring before and after chemotherapy on 45 pairs of computed tomography (CT) images in 36 patients who suffered from metastatic colorectal cancer (mCRC) with liver metastasis only. Cohen kappa was used to compare the agreement between VE and RECIST. Pearson correlation was performed for their comparison after cubic root transformation of the aggregate tumor volumes. Logistic regression was done to identify clinical and radiographic factors to account for the difference which may be predictive in overall response (OR). Results: There were 16 partial response (PR), 23 stable disease (SD) and 6 progressive disease (PD) cases with VE, and 14 PR, 23 SD and 8 PD with RECIST. VE demonstrated good agreement with RECIST (${\chi}$=0.779). Discordant objective responses were noted in 6 pairs of comparisons (13.3%). Pearson correlation also showed excellent correlation between VE and RECIST ($r^2$=0.966, p<0.001). Subgroup analysis showed that VE was in slightly better agreement with RECIST for enlarging lesions than for shrinking lesions ($r^2$=0.935 and $r^2$=0.780 respectively). No factor was found predictive of the difference in OR between VE and RECIST. Conclusions: VE exhibited good agreement with RECIST. It might be more useful than RECIST in evaluation shrinking lesions in cases of numerous and conglomerate liver metastases.

간세포암종은 만성 간질환과 간경변증을 동반하는 경우가 많고, 예후에 종양 인자 이외에도 잔존 간 기능이 주요한 영향을 미친다. 또한, 간세포암종에 대한 고위험인자를 가진 경우 특정한 영상 소견(예: 고혈관성)을 보이면, 조직검사 없이도 비침습적인 진단이 가능하다. 다른 고형암에서와 마찬가지로 수술적 절제, 방사선치료, 항암치료 등의 치료가 시행되기도 하지만, 간세포암종에서만 이루어진다고도 할 수 있는 간이식, 경동맥화학색전술, 고주파열치료술과 같은 치료 방법들이 시행되기도 한다. 종양의 다양성, 치료 방법의 다양성, 사회적 여건(의료 보건 체계, 의료 자원의 가용성 등) 등을 반영하며 여러 간세포암종 가이드라인들이 발표되어 왔으며, 각 가이드라인들은 여러 측면에서 유사하면서도 서로 상이하기도 하다. 본고에서는 다음의 간세포암종 진료 가이드라인들을 살펴보고, 가이드라인들의 특징과 앞으로 가이드라인에서 다루어야 할 부분 등에 대하여 논하고자 한다.

Since the introduction of chemotherapy for the treatment of childhood leukemia more than 50 years ago, the results of childhood cancer have improved dramatically. The 5-year survival rate of disease, many of which were uniformly fatal in the prechemotherapy era, reached to more than 75%. This remarkable improvement in survival is a direct result of the incorporation of chemotherapeutics into treatment regimens that previously relied only on surgery or radiotherapy for the primary tumor. The multimodality approach, which integrates surgery and radiotherapy to control local disease with chemotherapy to eradicate systemic or metastatic disease, has become the standard approach to treating most childhood cancers. The overall improvement in outcomes in childhood solid tumors has been related to the development of multidisplinary cooperative studies that has permitted the development of well-designed tumor treatment protocols characterized by uniform staging criteria, sharing informations in pathologic classification, uniform methods for tumor markers, oncogenes, and other biologic and genetic factors. Important advances in the biologic study of cancer and its genetic basis led to a number of observations that impact directly on the management of childhood solid tumors. Identification of specific genes, oncogenes, tumor markers, and other biologic and pathologic factors plays an important role in both staging and clarifying the risk categorization of individual patients. Treatment of the patient is influenced by the recognition of specific risk factors. This knowledge has resulted in a change in the approach to care based not only on staging criteria, but also on risk-based management. This concept uses various risk factors of outcomes. Risk-based management allows for each patient to maximize survival, minimize long-term morbidity and improve the quality of life, especially for children's growth and development.

Objective: To evaluate whether data acquired from perfusion computed tomography (PCT) parameters can aid in the prediction of treatment outcome after palliative chemotherapy in patients with unresectable advanced gastric cancer (AGC). Materials and Methods: Twenty-one patients with unresectable AGCs, who underwent both PCT and palliative chemotherapy, were prospectively included. Treatment response was assessed according to Response Evaluation Criteria in Solid Tumors version 1.1 (i.e., patients who achieved complete or partial response were classified as responders). The relationship between tumor response and PCT parameters was evaluated using the Mann-Whitney test and receiver operating characteristic analysis. One-year survival was estimated using the Kaplan-Meier method. Results: After chemotherapy, six patients exhibited partial response and were allocated to the responder group while the remaining 15 patients were allocated to the non-responder group. Permeability surface (PS) value was shown to be significantly different between the responder and non-responder groups (51.0 mL/100 g/min vs. 23.4 mL/100 g/min, respectively; p = 0.002), whereas other PCT parameters did not demonstrate a significant difference. The area under the curve for prediction in responders was 0.911 (p = 0.004) for PS value, with a sensitivity of 100% (6/6) and specificity of 80% (12/15) at a cut-off value of 29.7 mL/100 g/min. One-year survival in nine patients with PS value > 29.7 mL/100 g/min was 66.7%, which was significantly higher than that in the 12 patients (33.3%) with PS value ≤ 29.7 mL/100 g/min (p = 0.019). Conclusion: Perfusion parameter data acquired from PCT demonstrated predictive value for treatment outcome after palliative chemotherapy, reflected by the significantly higher PS value in the responder group compared with the non-responder group.

Background: Osteosarcomas are the most common solid malignancies of bone. In the last two decades there have been no concrete developments in their systemic treatment. In this trial we aimed to present our osteosarcoma patient clinical and demographic outcomes. Materials and Methods: Patients treated and followed up for osteosarcoma in Ankara Numune Education and Research Hospital from 2002 to 2012 were reviewed retrospectively. Results: A total of 21 patients (15 male, 6 female) were diagnosed with osteosarcoma. The disease was located at extremities in 76% and in 14% was metastatic at the time of diagnosis. Median disease free survival (DFS) was 36 months in non-metastatic patients and median progression free survival (PFS) was 2 months in metastatic patients (p<0.0001). Median overall survival (OS) was 80 months and 4 months, respectively (p=0.012). There were no survival differences in terms of presentation with pathological fracture, tumor size, tumor grade, alkaline phosphatase and lactate dehydrogenase level and type of chemotherapy regimen. Conclusions: Tumor site and stages are the most important prognostic factors for osteosarcoma. Extremity primary tumors have beter survival rates than non-extremity tumors. As a result of the use of effective chemotherapy the long term survival rates have improved from 10-20% to 60-70% in the last decades but we need more active agents, especially for metastatic cases.
