Here, we evaluated the therapeutic potential of antibodies (Abs) targeting cholinergic receptor nicotinic beta 2 subunit (CHRNB2) in gastric cancer. To investigate the effects of these Abs on malignant phenotypes in vitro and in mouse xenograft models, we generated gene knockouts through genome editing, performed RNA interference-mediated knockdown of gene expression, and ectopically expressed CHRNB2 in gastric cancer cells. The effects of anti-CHRNB2 Abs on the proliferation of cancer cells were evaluated both in vitro and in vivo. We determined the effects of Chrnb2 deficiency on mice and the clinical significance of CHRNB2 expression in gastric cancer clinical specimens. Knockdown of CHRNB2 attenuated gastric cancer cell proliferation, whereas forced overexpression of CHRNB2 increased cell proliferation. Knockout of CHRNB2 significantly influenced cell survival and functions associated with metastasis. The effects of polyclonal Abs targeting the C- and N-termini of CHRNB2 guided the development of anti-CHRNB2 monoclonal Abs that inhibited the growth of gastric cancer cells in vitro and in vivo. Pathway analysis revealed that CHRNB2 interfered with signaling through the PI3K-AKT and JAK-STAT pathways. Chrnb2-deficient mice exhibited normal reproduction, organ functions, and motor functions. CHRNB2 regulates multiple oncological phenotypes associated with metastasis, and blockade of CHRNB2 expression using specific Abs shows promise for controlling metastasis in gastric cancer.

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: Oligometastatic cancer (OM) is possibly associated with relatively better survival outcomes. We attempted to identify cases in line with this OM concept. PATIENTS AND METHODS: A total of 130 cases with unresectable metastatic pancreatic cancer underwent non-curative surgery from April 2001 to December 2019. Sites of metastasis, clinicopathological information, and surgical outcomes were collected to formulate a better definition of OM. RESULTS: OM criteria were defined as having metastasis to a single organ, few countable lesions and low serum cancer antigen 19-9 level. The median overall survival after non-curative surgery of OM cases was 13.0 months and was significantly better than that of non-OM cases (8.4 months, p=0.003). CONCLUSION: We propose single-organ metastasis of limited tumor volume (H1 or P1/2 by the Japanese Society of Cancer of the Colon and Rectum classification) and low serum cancer antigen 19-9 level (<2,000 U/ml) as new criteria for defining OM pancreatic cancer.

BACKGROUND: The Apolipoprotein-related MORtality RISk (AMORIS) study in Sweden revealed that serum uric acid (SUA) was significantly associated with hepatobiliary cancer occurrence. However, the association with postoperative hepatocellular carcinoma (HCC) recurrence has not been reported. METHODS: A total of 256 surgically resected HCC patients were included (from January 2003 to December 2017) in this study. Comparisons in terms of clinicopathologic factors and long-term outcomes were made between patients with high SUA (>6.1 mg/dl) at the time of hepatectomy and low SUA. Besides, SUA data at one postoperative year (1POY) of the same cohort were collected and analyzed in the same manner. RESULTS: About 88.8% of tumor relapse sites were the remnant liver. High SUA levels were associated with male and well-differentiated HCCs. Recurrence-free survival (RFS) of high SUA patients was significantly inferior to low SUA patients [median survival time (MST): 22.7 vs. 28.5 mo, P = 0.033], whereas no difference was observed in overall survival (MST: both not reached, P = 0.771). RFS of high SUA patients at 1POY also showed significantly poorer outcomes than low SUA patients (MST: 29.3 vs. 57.0 mo, P = 0.049). CONCLUSIONS: High SUA implies a significant risk factor of activating hepatocarcinogenesis. Keeping the SUA level low may be recommended after HCC resections.

International journal of clinical oncology Vol. 26 ( 7 ) page： 1264 - 1271 2021.7

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: The carcinoembryonic antigen (CEA) "value" itself is often useless in patients with a normal CEA level at initial presentation and those with tumor-irrelevant elevated CEA. Although the unified marker using CEA has been desirable for recurrent tumor staging as well as for primary tumor staging, little is known concerning its relationship with the survival of patients with recurrent colorectal cancer in particular. METHODS: This retrospective historical study included patients who experienced disease relapse after curative surgery for stage I-III colorectal cancer between 2006 and 2018. A total of 129 patients with recurrent disease after curative surgery for colorectal cancer were included. We focused on the CEA "ratio" (CEA-R: the ratio of the CEA level at the time of recurrence to that measured 3 months before recurrence) and aimed to evaluate the correlation between CEA-R and survival in recurrent colorectal cancer. RESULTS: Patients with a high CEA-R (≥ 2) exhibited significantly worse 2 year survival than those with a low CEA-R (< 2) (88.1% vs. 44.9%, P < 0.001), irrespective of the CEA value before primary resection. Multivariate analyses demonstrated that the CEA-R (HR; 3.270, 95% CI 1.646-6.497, P = 0.001) was a significant prognostic factor. CONCLUSION: The CEA-R is a potential marker stratifying the survival of patients with disease relapse who exhibit aggressive biology at recurrent disease foci. As a novel marker, the CEA-R would serve as a clinical guide for tailoring treatment strategies at the time of disease relapse in patients with colorectal cancer.

European journal of surgical oncology : the journal of the European Society of Surgical Oncology and the British Association of Surgical Oncology Vol. 47 ( 5 ) page： 1005 - 1011 2021.5

Language：English Publishing type：Research paper (scientific journal)

INTRODUCTION: The oncological benefit of neoadjuvant chemotherapy (NAC) alone for locally advanced rectal cancer (LARC) remains controversial. The aim of this study was to clarify the clinical risk factors for poor prognosis before and after NAC for decision making regarding additional treatment in patients with LARC. MATERIALS AND METHODS: We examined a total of 96 patients with MRI-defined poor-risk locally advanced mid-low rectal cancer treated by NAC alone between 2006 and 2018. Survival outcomes and clinical risk factors for poor prognosis before and after NAC were analyzed. RESULTS: In the median follow-up duration after surgery of 60 months (3-120), the rates of 5-year overall survival (OS), relapse-free survival (RFS), and local recurrence (LR) were 83.6%, 78.4%, and 8.2%, respectively. In the multivariate analyses, patients with cT4 disease had a significantly higher risk of poor OS (HR; 6.10, 95% CI; 1.32-28.15, P = 0.021) than those with cT3 disease. After NAC, ycN+ was significantly associated with a higher risk of poor OS (HR; 5.92, 95% CI; 1.27-27.62, P = 0.024) and RFS (HR; 2.55, 95% CI; 1.01-6.48, P = 0.048) than ycN-. In addition, patients with CEA after NAC (post-CEA) ≥ 5 ng/ml had a significantly higher risk LR (HR; 5.63, 95% CI; 1.06-29.93, P = 0.043). CONCLUSION: NAC alone had an insufficient survival effect on patients with cT4 disease, ycN+, or an elevated post-CEA level. In contrast, NAC alone is a potential treatment for other patients with LARC.

BACKGROUND: Gastric cancer (GC) with hepatic metastasis has a poor prognosis. Understanding the molecular mechanisms involved in hepatic metastasis may contribute to the development of sensitive diagnostic biomarkers and novel therapeutic strategies. METHODS: We performed transcriptome analysis of surgically resected specimens from patients with advanced GC. One of the genes identified as specifically associated with hepatic metastasis was selected for detailed analysis. GC cell lines with knockout of the candidate gene were evaluated in vitro and in vivo. Expression of the candidate gene was analysed in GC tissues from 300 patients. RESULTS: Ethanolamine kinase 2 (ETNK2) was differentially upregulated in GC patients with hepatic metastasis. ETNK2 expression was elevated in GC cell lines derived from haematogenous metastases. ETNK2 knockout significantly suppressed proliferation, invasion, and migration; increased apoptosis; reduced Bcl-2 protein expression; and increased phosphorylated p53 expression. In mouse xenograft models, ETNK2 knockout virtually abolished hepatic metastasis. Stratification of GC patients based on ETNK2 mRNA level revealed significant associations between high ETNK2 tumour expression and both hepatic recurrence and worse prognosis. CONCLUSIONS: Upregulation of ETNK2 in GC enhances hepatic metastasis, possibly via dysregulation of p53-Bcl-2-associated apoptosis. ETNK2 expression may serve as a biomarker for predicting hepatic recurrence and a therapeutic target.
