ABSTRACT

Objective: To explore the efficacy and safety of hepatic arterial infusion chemotherapy(HAIC) for unresectable hepatitis B-related intrahepatic cholangiocarcinoma(ICC). Methods: This is a retrospective controlled study. Data from 140 unresectable ICC patients who received HAIC treatment at Sun Yat-sen University Cancer Center from March 2015 to June 2023 were retrospectively collected, including 72 patients in the hepatitis B surface antigen(HBsAg)negative group (43 males and 29 females, aged (59.6±9.5)years(range: 34 to 81 years)), 68 cases in the HBsAg-positive group (48 males, 20 females, aged (53.4±11.4)years(range: 29 to 82 years)). HAIC treatment used the FOLFOX regimen combined with oxaliplatin, leucovorin,and fluorouracil. The differences in effects, prognosis,and adverse reactions between the two groups of patients after HAIC treatment were analyzed. All variables were expressed as categorical data. The χ2 test or Fisher's exact probability method was used to compare between groups. The Kaplan-Meier method was used to draw survival curves. The difference of survival curve between groups were compared through the Log-rank test. Results: According to the Response Evaluation Criteria in Solid Tumors(RECIST) version 1.1,the objective response rate(ORR) of the HBsAg-negative group was 23.2%(16/69),and the ORR of the HBsAg-positive group was 40.3%(25/62). The difference in ORR between the two groups was statistically significant(χ2=4.459,P=0.035). According to the modified RECIST(mRECIST) criteria,the ORR of the HBsAg-negative group was 27.5%(19/69), and the ORR of the HBsAg-positive group was 45.2%(28/62). The difference in ORR between the two groups was statistically significant(χ2=4.410,P=0.036). The median progression-free survival(PFS) of the HBsAg-negative group and the positive group were 7.1 months(95%CI: 5.8 to 13.2 months) and 7.3 months (95%CI: 5.7 to 10.3 months), respectively, and the median overall survival(OS) were 16.3 months (95%CI: 12.5 to 33.9 months) and 15.9 months (95%CI: 9.2 to 20.7 months) respectively. There were no statistically significant differences in PFS and OS between the two groups (both P>0.05). The main serious adverse reactions of the two groups of patients included increased AST, increased ALT, thrombocytopenia,and neutropenia. There were no statistically significant differences in various adverse reactions between the two groups after HAIC treatment (all P>0.05). Conclusion: Patients with HBsAg-positive unresectable ICC are more likely to benefit from HAIC treatment.

ABSTRACT

Objective: To determine the seroprevalence of celiac disease in susceptible population, and to analyze the relationship between demographic characteristics, dietary habits, lifestyle and serological positivity so as to provide guidance for the prevention and treatment of celiac disease in Southern China. Methods: A total of 1 273 individuals who participated in Guangdong Province Health Screening Program in 2015, were selected as serologically positive subjects of celiac disease, including people with irritable bowel syndrome, colitis, diarrhea, anemia, low BMI, short stature, type 1 diabetes mellitus (T1DM), rheumatoid arthritis (RA), ankylosing spondylitis, psoriasis and bristol grade=6 or 7. All subjects were tested for serum IgA anti-tissue transglutaminase antibodies (TTGA), IgA antibodies against deamidated gliadin peptides(DGPA) and IgG against deamidated gliadin peptides (DGPG). Dietary habits, lifestyle and demographic characteristics were compared in subgroups. Results: The seroprevalence of celiac disease in susceptible population was 0.94% (95%CI 0.54%-1.64%) including 0.08% (1/1 273) for TTGA, 0.47% (6/1 273) for DGPA, and 0.39% (5/1 273) for DGPG. The seropositive rate was 3.6% (1/28) in patients with psoriasis, 2.1% (2/95) in the low BMI group, 1.9% (1/53) in T1DM group, 1.8% (3/169) in diarrhea group and 1.1% (5/463) in RA group. No significant difference was found in age, gender, high carbohydrate diet or lifestyle between the negative and the positive subjects. Conclusions: In Southern China, the seropositive rate of celiac disease is 0.94% in susceptible population, which prompts an urgent need of serological screening for early diagnosis.

ABSTRACT

Metastasis is the major cause of death in colorectal cancer (CRC). Although multiple genes have been identified to be responsible for the development of CRC, the molecular changes that enable CRC cells to undergo early local invasion and to form distant metastatic colonies still remain largely unknown. Herein, we investigated the role of Forkhead box protein C2 (FOXC2) and explored the underlying mechanisms in invasion and metastasis of CRC. We show that both high FOXC2 expression and nuclear localization of FOXC2 are significantly correlated with advanced TNM (T=primary tumor; N=regional lymph nodes; M=distant metastasis) stages. FOXC2 enhanced the invasive abilities of CRC cells in vitro and promoted local invasion and distant metastasis in an orthotopic mouse metastatic model of CRC. Microarray analysis revealed that overexpression of FOXC2 increased the proto-oncogene MET tyrosine kinase expression and activated the hepatocyte growth factor (HGF)-MET signaling pathway. Furthermore, luciferase reporter assays and chromatin immunoprecipitation assays revealed that FOXC2 directly associated with MET promoter to increase the transcriptional activity of MET. Inhibition of MET attenuates the invasive phenotype and metastatic potential of FOXC2-overexpressing CRC cells, indicating that MET is a major mediator of FOXC2-promoted metastasis. In addition, FOXC2 expression was positively correlated with MET expression in CRC tissue samples. Our findings suggest that FOXC2 has a crucial role in CRC metastasis by regulating HGF-MET signaling via inducing MET expression, highlighting FOXC2 as a potential therapeutic target for preventing or reducing metastasis in CRC.
