Objective: Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are the most common colorectal cancer markers. We aimed to identify the appropriate clinical conditions for measuring serum CEA and CA19-9 levels before surgery and during follow-up. Methods: This study included 1275 colorectal cancer patients who were divided into 3 groups according to preoperative CEA levels (group A, ≤5 ng/mL; group B, >5–≤11 ng/mL; group C, >11 ng/mL). Each group was subdivided into 2 groups according to preoperative CA19-9 levels (cutoff level: ≤37 U/mL). Recurrence and survival rates were analyzed. Results: Recurrence rate, disease-free survival after curative surgery, and prognosis were significantly worse in group A and B patients with high CA19-9 levels. At recurrence, CEA levels showed a greater increase in group B and C patients; CA19-9 levels increased in group A patients with high CA19-9 levels. At recurrence, high serum CA19-9 levels were observed in group A patients with high preoperative serum CA19-9 levels, even if the serum CEA level did not increase. Preoperative CA19-9 levels could predict recurrence and prognosis in groups A and B. Conclusion: Periodic CA19-9 determination is useful for monitoring recurrence among group A patients with high CA19-9 levels.

Abstract: Colorectal cancer is a serious health problem in Indonesia as well as in North Sulawesi. Serum carcinoembryonic antigen (CEA) is a progmostic factor in patients with this disease. This study was aimed to obtain the correlation between the histopathological differentiation stage and serum CEA level in colorectal cancer patients at Prof. Dr. R. D. Kandou Hospital Manado. This was an analytical correlation study. Subjects were colorectal cancer patients who had preoperative serum CEA level and histopathological differentiation stage results. Data were analyzed with Anova test (variant analysis) and Spearman Rho test. The results showed that there were 58 colorectal cancer patients enrolled in this study. The patients’ data were obtained from the Digestive Surgery clinic and nursery room of Prof. Dr. R. D. Kandou Hospital Manado. Of the 58 patients, 37 (63.79%) had moderate differentiated colorectal cancer. Related to serum CEA level, 23 patients (39.65%) had moderate differentiated colorectal cancer with serum CEA level 20-100 ng/ml. The Spearman Rho test showed that there was a positive correlation between serum CEA level and histopathoplogical differentiation stage of cancer (r = 0.877 and P = 0.001). Conclusion: There was a significant correlation between serum CEA level and histopathological differentiation stage of colorectal cancer. The better the differentiation stage, the higher the serum CEA level.Keywords: carcinoembryonic antigen, colorectal cancer, differentiation stageAbstrak: Karsinoma kolorektal (KKR) telah menjadi masalah kesehatan yang serius di Indonesia dan Sulawesi Utara pada khususnya. Kadar carcinoembryonic antigen (CEA) merupakan salah satu faktor prognostik pada penderita KKR. Penelitian ini bertujuan untuk mengetahui hubungan antara derajat diferensiasi histopatologik dengan kadar CEA dalam serum pada pasien KKR di RSUP Prof. Dr. R. D. Kandou Manado. Jenis penelitian ini ialah analitik korelatif. Subyek penelitian ialah 58 pasien KKR yang mempunyai hasil pemeriksaan kadar CEA serum preoperasi dan pemeriksaan derajat diferensiasi histopatologik. Analisis statistik menggunakan uji Anova (analisis variansi) dan korelasi Spearman Rho. Data pasien diambil dari pasien yang datang dan kontrol di Poliklinik Bedah Digestif serta dari ruang perawatan Bedah Digestif RSUP Prof. Dr. R. D. Kandou Manado. Hasil penelitian memperlihatkan derajat diferensiasi tumor kolorektal terbanyak ialah diferensiasi sedang/moderate differentiated yaitu 37 pasien (63,79%). Bila dihubungkan dengan nilai CEA serum, yang terbanyak ditemukan ialah jenis diferensiasi sedang pada pasien dengan kadar CEA serum 20-100 ng/ml sebanyak 23 orang (39,65%). Uji Spearman Rho memperlihatkan bahwa kadar CEA berkorelasi positif dengan derajat diferensiasi KKR (r = 0,877 dan P = 0,0001). Simpulan: Terdapat korelasi bermakna antara kadar CEA serum dan derajat diferensiasi kanker kolorektal. Derajat diferensiasi KKR yang baik memiliki kadar CEA yang tinggi.Kata kunci: carcinoembryonic antigen, karsinoma kolorektal, derajat differensiasi

Serum tumor markers such as alpha-fetoprotein (AFP), carcinoembryonic antigen, carbohydrate antigen (CA) 19-9, CA242, and CA50 were analyzed to evaluate their diagnostic values in single and combined tests for distinguishing intrahepatic cholangiocarcinoma (ICC) from hepatocellular carcinoma (HCC). Preoperative serum levels of AFP, carcinoembryonic antigen, CA19-9, CA242, and CA50 were measured in 45 ICC and 76 HCC patients. The serum levels and the positive rate of AFP, CA19-9, and CA242 were significantly different between the ICC patients and HCC patients. Although AFP (—) was the most sensitive assay for distinguishing ICC from HCC (91.1%), its specificity was significantly lower than that of CA242 (+) and CA19-9 (+). The combination of AFP (-) and CA242 (+) afforded a high specificity of 94.3 per cent and showed highest accuracy (78.5%). Evaluation of patients without liver cirrhosis also showed similar results. The diagnostic value of CA242 (+) is better than that of CA19-9 (+) and AFP (-) in distinguishing ICC from HCC. Combined detection of AFP (—) and CA242 (+) can improve the specificity and accuracy of diagnosing ICC.

Objective The purpose of this study was to explore serum miR-135a-5p expression in colorectal cancer and examine the potential usefulness of this molecule as a biomarker for diagnosis in colorectal cancer. Methods Serum samples were collected from 60 patients with primary colorectal cancer, 40 patients with colorectal polyps and 50 healthy controls. Serum miR-135a-5p expression levels were detected by reverse transcription quantitative real-time quantitative polymerase chain reaction. Serum carcinoembryonic antigen and carbohydrate antigen 199 concentrations were detected by MODULAR ANALYTICS E170. Results The relative expression level of serum miR-135a-5p in colorectal cancer patients, colorectal polyps patients and healthy controls was 2.451 (1.107, 4.413), 0.946 (0.401, 1.942) and 0.949 (0.194, 1.415), respectively, indicating that it was significantly higher in colorectal cancer patients than that in the other two groups ( U = 351.0, 313.0, both P < 0.001). Additionally, it was significantly correlated with different degrees of tumour differentiation ( U = 215.0, P = 0.029) and different tumour stages ( U = 202.0, P = 0.013). There was no significant correlation between the relative expression of serum miR-135a-5p and carcinoembryonic antigen ( r2 = 0.023, P = 0.293) or carbohydrate antigen 199 ( r2 = 0.067, P = 0.068) in colorectal cancer patients. Compared with colorectal polyps group, AUCROC of serum miR-135a-5p in colorectal cancer group was 0.832 with 95% CI 0.73–0.93; compared with healthy control group, AUCROC was 0.875 with 95% CI 0.80–0.95. Conclusion Serum miR-135a-5p expression in colorectal cancer patients was higher than that in patients with colorectal polyps and healthy controls, suggesting that serum miR-135a-5p may prove to be an important biomarker for auxiliary diagnosis of colorectal cancer.
