Aims: To investigate the incidence of ordering tests for tumor markers which are used in cancer diagnosis, follow-up treatment and detection of recurrence, the rate of elevation in benign diseases and which clinics order them frequently. Materials and Method: Data for the tumor markers carbohydrate antigen 19-9 (CA 19-9), carcinoembryonic antigen (CEA), cancer antigen 125 (CA 125), cancer antigen 15-3 (CA 15-3) and alpha-fetoprotein (AFP) that were ordered by all the clinics in our Hospital between 2010 and 2011 were screened. When excluding repeated orders the results of 3,416 patients were available. It has been determined that in which benign diseases were the tumor markers frequently ordered and which of these conditions had high levels of them. Results: CA 19-9 was ordered for 1,858 patients 191 (10.3%) were malignant while 1667 (89.7%) were ordered in benign diseases. For CEA the total was 1,710, 226 (13.2%) malignant and 1484 (86.8%) benign, and for CA 125 1267, 111 (8.8%) malignant and 1156 (91.2%) benign. AFP was ordered for 1687 cases, 80 (4.7%) malignant but 1607 (95.3%) benign. CA 15-3 was ordered 1449 times, 174 (12%) for malignant and 1275 (88%) for benign diseases. In all cases, considerable proportions were positive. Conclusions: It was shown that clinicians frequently order tumor markers for benign conditions. The findings of this study has shown that tumor markers are used widely without indications as cancer screening tests.

Objective: To compare expression level of serum tumor associated materials (TAM) with several conventional serum tumor biomarkers, eg., carcinoembryonic antigen (CEA), carbohydrate antigen19-9 (CA19-9), carbohydrate antigen 15-3 (CA15-3), alpha-fetoprotein(AFP), in selected solid tumors. Methods: Patients diagnosed histologically or cytologically with liver, breast, esophageal, gastric, colorectal or pancreatic cancers were enrolled into this study. After diagnosis, the level of TAM was determined by chemical colorimetry, and levels of conventional tumor markers was measured by chemiluminescence methods. Results: A total of 560 patients were enrolled into this study. No statistically significant difference was detected in TAM and the above mentioned tumor biomarkers in terms of their positivity and negativity ( P>0. 05). Conclusions: Detection of TAM in liver, breast, esophageal, gastric, colorectal, and pancreatic cancer patients demonstrates a good accordance with CEA, CA199, CA153, and AFP, thus suggesting that further study is warranted to verify whether TAM could be a surrogate for these conventional biomarkers.

복막 가성점액종은 표준치료인 종양감축수술과 함께 복강 내 고온열 항암요법과의 병합치료로 생존율의 향상을 기대할 수 있다. 재발성 병변에 대해서는 추가적인 종양감축 수술이 권고되고 있지만, 치료시기에 따른 이환율과 사망률의 차이가 있어 조기발견이 중요하다. 수술 전 혈청 종양표지자 검사의 수치 이상 여부에 따른 재발과 생존율의 상관관계를 알아보고자 하는 연구들은 있지만, 추적관찰 중 수치 이상에 따른 재발여부에 관한 연구는 거의 없다. 저자들은 CSR과 HIPEC, 그리고 전신 항암화학요법을 시행받은 환자에서 CEA의 수치 상승이 질병의 재발과 상관관계가 있었음을 경험하였기에 보고하는 바이다.

Purpose: The prognostic significance of peri-operative serum carcinoembryonic antigen (CEA) and carbohydrate antigen (CA)19-9 determination in patients with gastric cancer has been controversial. This study was performed to evaluate the significance of CEA and CA19-9 as clinical predictors of prognosis. Materials and Methods: The correlations between peri-operative serum CEA/CA19-9 levels and clinicopathologic factors were evaluated retrospectively in gastric cancer patients who had undergone curative surgery during the period from January 1995 to December 1998 at the Department of Surgery, Yonsei University College of Medicine. Results: The positive rates for CEA and CA19-9 were $17.9\%$ and $18.4\%$, respectively. The CEA positivity was related to the depth of invasion (P=0.040), lymph-node metastasis (P=0.000), and stage (P=0.001). The CA19-9 positivity was significantly related to the depth of invasion (P=0.000), lymph-node status (P=0.000), and stage (P=0.000). The positive rate of combined assay of pre-operative CEA and CA19-9 was $30.0\%$ There were statistically significant correlations with stage, depth of invasion, or degree of lymphnode metastasis in the combined assay. The survival rates according to the positivity of CEA and to the positivity of CA19-9 were clearly different (P=0.000). Conclusion: It should be stressed that even a simple blood test prior to surgery could be useful in establishing the depth of invasion, the status of lymph-node involvement, and the prognosis. For improved survival, an aggressive lymphadenectomy and adjuvant chemotherapy should be considered for patients with positive levels of pre-operative CA19- 9.

Objective : This report is aimed to investigate the effectiveness of traditional korean therapy including intravenous Cultivated Wild Ginseng Pharmacopuncture (CWGP) and Soram immunopharmacopuncture with XELOX chemotherapy in treating metastatic colorectal cancer patient. Methods : A 47-year-old woman who was diagnosed as metastatic colorectal cancer on Oct 2011 was concurrently treated with traditional Korean therapy (TKT) and XELOX (capecitabine plus oxaliplatin) for 7 months. TKT includes intravenous CWGP, Soram immuno-pharmacopuncture, acupuncture, moxibustion, and herbal medicine. The effectiveness of therapies was evaluated with computed tomography and tumor marker levels such as carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9). And pain on the lateral abdomen was recorded with Visual Analogue Scale (VAS). Results : The tumor mass size of metastatic liver was decreased from 10 cm to 4.3 cm. The tumor marker levels such as CEA and CA19-9 are also decreased. From these results, this case report suggests that the TKT with palliative chemotherapy may be a useful method to treat unresectable metastatic colorectal cancer.

The CA(carbohydrate antigen)19-9 is complex protein that can be used as an important marker which aids the clinical diagnosis and prognosis of various pancreaticobiliary tumors. However, it was also reported that there were some CA19-9 positive patients with benign disease as using RIA method. The purpose of this study is to evaluate the clinical usefulness of serum level of CA19-9 with RIA(radioimmuno assay), CIA(chemiluminescence immuno assay), and conventional liver function tests. The correlation between CIA and RIA in CA19-9 of pancreatobiliary disease was 0.9833(P<0.01). Also, the correlations between CIA and RIA in CA19-9 of benign and malignant pancreaticobiliary tumor patients was 0.8714(P<0.01) and 0.9727(P<0.01) respectively. The correlation between CA19-9 and ALP was 0.5140(P<0.01) and CEA was 0.3385(P<0.05) as using CIA. The measurement of serum CA19-9 levels by CIA method may be useful in differentiating patients with malignant disease from those with benign disease in pancreaticobiliary tumors.

Background: To explore whether combined detection of serum tumor markers (CEA, CA72-4, CA19-9 and TSGF) improve the sensitivity and accuracy in the diagnosis of gastric cancer (GC). Materials and Methods: An automatic chemiluminescence immune analyzer with matched kits were used to determine the levels of serum CEA, CA72-4, CA19-9 and TSGF in 45 patients with gastric cancer (GC group), 40 patients with gastric benign diseases (GBD group) hospitalized in the same period and 30 healthy people undergoing a physical examination. The values of those 4 tumor markers in the diagnosis of gastric cancer was analyzed. Results: The levels of serum CEA, CA72-4, CA19-9 and TSGF of the GC group were higher than those of the GBD group and healthy examined people and the differences were significant (P<0.001). The area under receiver operating characteristic (ROC) curves for single detection of CEA, CA72-4, CA19-9 and TSGF in the diagnosis of GC was 0.833, 0.805, 0.810 and 0.839, respectively. The optimal cutoff values for these 4 indices were 2.36 ng/mL, 3.06 U/mL, 5.72 U/mL and 60.7 U/mL, respectively. With combined detection of tumor markers, the diagnostic power of those 4 indices was best, with an area under the ROC curve of 0.913 (95%CI 0.866~0.985), a sensitivity of 88.9% and a diagnostic accuracy of 90.4%. Conclusions: Combined detection of serum CEA, CA72-4, CA19-9 and TSGF increases the sensitivity and accuracy in diagnosis of GC, so it can be regarded as the important means for early diagnosis.

We report on a rare case involving a 23-year-old female patient with mediastinal cystic mass complicated with acute pericarditis and cardiac tamponade. Pericardial fluid demonstrated lymphocyte-predominant exudate and the level of carcinoembryonic antigen (CEA) was unexpectedly elevated. Successive aspiration of mediastinal cystic mass revealed a very high level of CEA (>100,000 U/mL) and carbohydrate antigen 19-9 (>15,000 ng/mL). This patient was clinically diagnosed as an infected bronchogenic cyst complicated with pericarditis and cardiac tamponade. The treatment resulted in alleviation of her symptoms.

Background: To verify whether serum tumor abnormal protein (TAP) would correlate with the responsiveness of palliative chemotherapy in patients with advanced gastric cancer, and the variation of conventional serum tumor markers e.g., carcinoembryonic antigen (CEA), antigen 125 (CA125),carbohydrate antigen19-9 (CA19-9) of adjuvant chemotherapy in patients with early gastric cancer. Materials and Methods: Patients with histologically confirmed gastric cancer and treated with chemotherapy were enrolled into this study. TAP values of these patients were determined by detecting abnormal sugar chain glycoprotein in serum, combined with the area of agglomerated particles. For patients with advanced gastric cancer, responsiveness of palliative chemotherapy was compared with variation of TAP and the relation between variation of TAP and tumor markers in patients with early gastric cancer was analyzed. Results: Totally 82 gastric cancer patients were enrolled into this study. The value of TAP is more closely related to responsiveness of palliative chemotherapy for patients with advanced gastric cancer. The correlation between TAP and responsiveness to palliative chemotherapy is stronger than the correlation between several conventional serum tumor markers (CEA, CA125 and CA199). The variation of TAP was also positively correlated with the trend of CA125 in adjuvant chemotherapy. Conclusions: TAP is sensitive in monitoring the responsiveness to palliative chemotherapy in patients with advanced gastric cancer. But this result should be confirmed by randomized clinical trials for patients with gastric cancer.
