AIM： To investigate the tumorigenicity of lung cancer by learning the accumulation of p53 and the exposure of cytokeratin 18 neo-epitope(CK-18neo) related to the clinicopathological parameters in non-small cell lung cancer(NSCLC). METHODS: To detect the monoclonal antibodies of p53 and M30 CytoDEATH(specific antibody for CK-18neo) in 62 cases of NSCLC (included 29 cases of squamous cell carcinoma and 33 cases of adenocarcinoma) and 10 cases of control group by adopting immunohistochemistry assay (LSAB). Moreover, the immunoreactivity of p53 was quantitatively evaluated with positive unit (PU). RESULTS: (1) p53 immunoreactivity was positive in 15 of 29 squamous cell carcinoma (51.72%), 15 of 33 adenocarcinoma (45.45%), 30 of 62 NSCLC (48.39%). In 10 control cases was negative. There were significant differences between these groups (P＜0.01). (2)In 62 cases of NSCLC, AI% of M30 is 1.10%, and in 29 cases of squamous cell carcinoma is 0.95%, and in 33 cases of adenocarcinoma is 1.24%. In 10 control cases, the AI% is 1.06%. There is not significant difference among these groups . (3) According to the results of Pearson's correlation analysis, we found positive linear correlation between the immunoreactivity of p53（-/+）, p53（5 degrees）and p53（PU）(P＜0.01). CONCLUSION: Our results suggested that the pathogenesis of NSCLC might be related to the mutation of gene p53 and cell excessive proliferation and insufficient apoptosis.

The abnormal expression (level and status) of the key molecular targets of tumors is related to molecular targeted therapy response, effect, and prognosis. Therefore, the expression level and status of key molecular targets of tumors must be accurately evalu-ated, regardless of the status before, during, and after receiving targeted therapy. Molecular imaging is a non-invasive method used for qualitative and quantitative research on key molecular targets of tumor in vivo and in real-time. This technique is also employed to screen treatment beneficiaries, guide therapy, and evaluate prognosis. This paper reviews the application progress of molecular imag-ing using various probes in cancer targeted therapy. The clinical value of molecular imaging in tumor targeted therapy is further ana-lyzed to promote the development of novel targeted therapy for tumors.

Objective:To compare the clinical efficacy of laparoscopic and open surgery in the treatment of hepatocellular carcinoma (HCC) at specific sites of liver.Methods:Data of patients with HCC undergoing hepatectomy in Mengchao Hepatobiliary Hospital of Fujian Medical University from September 2014 to May 2019 were retrospective analyzed. A total of 205 patients were enrolled, including 174 males and 31 females, aged (56.7±11.3) years. According to the surgical methods, patients were divided into laparoscopic group ( n=105) and open group ( n=100). The Child-Pugh score, maximum tumor diameter, tumor location, intraoperative blood loss, postoperative complication rate, liver function(glutamate transaminase, alanine transaminase, etc.) and length of hospital stay were compared between the two groups. Postoperative survival and recurrence were followed up. Survival curves and rates were analyzed by Kaplan-Meier and log-rank test. Results:There were no significant differences in Child-Pugh score, maximum tumor diameter, tumor location between the two groups. Compared to the open group, the laparoscopic group had a decreased blood loss [100 (50, 200) ml vs 150 (100, 200) ml], a lower incidence of postoperative complications[7.6%(8/105) vs 17.0%(17/100)], and a shorter hospital stay [(8.6±1.9) days vs (13.0±3.4) days](all P<0.05). The postoperative glutamate transaminase and alanine transaminase levels were lower in the laparoscopic group than those in the open group. The 1, 3, 5-year overall survival and recurrence-free survival were not significantly different between the two groups (χ 2=0.56, 0.21, P=0.456, 0.648). Conclusion:Laparoscopic surgery in the treatment of HCC at specific sites of liver is a safe, feasible and effective procedure.
