Abstract:
Objective To investigate the application value of serum tumor necrosis factor alpha (TNF-α) expression in diagnosing colorectal cancer (CRC).Methods One hundred and thirty inpatients with CRC in our hospital from February 2015 to November 2016 were selected and divided into 90 cases of CRC confirmed by operation and histopathology(CRC group),including intestinal cancer with and without metastasis,and 40 cases of benign colorectal diseases(colonrectal benign disease group),at the same time 40 persons undergoing physical examination were selected as the healthy control group.The levels of TNF-α,carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 724 were collected in all subjects.The data of various groups were not normally distributed,and the nonparametric statistical method was used to analyze and compare.Results Serum TNF-α level in clinical TNM stage Ⅱ(median 9.47 pg/mL),Ⅲ(9.95 pg/mL) and Ⅳ(9.67 pg/mL) of the CRC group was significantly higher than that in TNM stage Ⅰ(6.59 pg/mL);which in the CRC with metastasis group (9.95 pg/mL) was higher than 8.03 pg/mL in CRC without metastasis group,the difference was statistically significant (P<0.05);the TNF-α expression had no obvious difference among different ages and between different genders(P>0.05).The area under the ROC curve in each test index:TNF-α was 0.868,CEA was 0.912,CA724 was 0.523,and which of their joint detection was 0.940.Conclusion The expression of TNF-α is increased in the occurrence and development process of CRC,its serum level detection has certain clinical application value,the TNF-α expression has no obvious difference in the subjects with different ages and different sexes and has wide suitability.The combine detection of serum TNF-α,CEA and CA724 in the patients with CRC significantly increases the level,the combined detection of 3-index can have complementary advantages to increase the sensitivity of CRC diagnosis,which serve as the significant indexes in CRC early diagnosis,therapeutic effect evaluation and prognosis monitoring.
