PURPOSE: The neoadjuvant rectal (NAR) score is a promising indicator of survival after preoperative chemoradiotherapy for rectal cancer. However, its effectiveness after neoadjuvant chemotherapy (NAC) alone has not been fully investigated. METHODS: We analyzed data retrospectively on 61 patients with rectal cancer, who received NAC followed by surgical resection between 2010 and 2015, and evaluated the impact of the NAR score on survival. RESULTS: The median NAR score was 14.9. Of the 61 patients, 13, 35, and 13 were classified as having NAR-low (< 8), NAR-intermediate (8-16), and NAR-high (> 16) scores, respectively. The median observation period was 49.0 months. According to the NAR score, the 3-year DFS in the NAR-low group was 100%, which was significantly better than that in the NAR-intermediate (64.8%, p = 0.041), and NAR-high (61.5%, p = 0.018) groups. When the NAR-intermediate and NAR-high groups were investigated as a single high-risk group, the 3-year DFS of the patients who received adjuvant chemotherapy was 88.7%, which was significantly better than that of the patients who did not receive adjuvant chemotherapy (53.3%, p = 0.042). CONCLUSIONS: The NAR score may predict the DFS and could serve as a favorable indicator of adjuvant chemotherapy after NAC alone.

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

BACKGROUND: We aimed to clarify the role of potassium voltage-gated channel subfamily J member 15 (KCNJ15) in esophageal squamous cell carcinoma (ESCC) cells and its potential as a prognosticator in ESCC patients. METHODS: KCNJ15 transcription levels were evaluated in 13 ESCC cell lines and polymerase chain reaction (PCR) array analysis was conducted to detect coordinately expressed genes with KCNJ15. The biological functions of KCNJ15 in cell invasion, proliferation, migration, and adhesion were validated through small interfering RNA-mediated knockdown experiments. Cell proliferation was further evaluated through the forced expression experiment. KCNJ15 expression was detected in 200 ESCC tissues by quantitative real-time reverse transcription PCR (qRT-PCR) and analyzed in 64 representative tissues by immunohistochemistry. Correlations between KCNJ15 expression levels and clinicopathological features were also analyzed. RESULTS: The KCNJ15 expression levels varied widely in ESCC cell lines and correlated with COL3A1, JAG1, and F11R. Knockdown of KCNJ15 expression significantly repressed cell invasion, proliferation, and migration of ESCC cells in vitro. Furthermore, overexpression of KCNJ15 resulted in increased cell proliferation. Patients were stratified using the cut-off value of KCNJ15 messenger RNA (mRNA) levels in 200 ESCC tissues using receiver operating characteristic curve analysis; the high KCNJ15 expression group had significantly shorter overall and disease-free survival times. In multivariable analysis, high expression of KCNJ15 was identified as an independent poor prognostic factor. Staining intensity of in situ KCNJ15 protein expression tended to be associated with KCNJ15 mRNA expression levels. CONCLUSIONS: KCNJ15 is involved in aggressive tumor phenotypes of ESCC cells and its tissue expression levels may be useful as a prognosticator of patients with ESCC.

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

BACKGROUND: Primary tumor location is a critical prognostic factor that also impacts the efficacy of anti-epidermal growth factor receptor (EGFR) therapy in wild-type RAS (KRAS/NRAS) metastatic colorectal cancer (CRC). However, the association between the incidence of BRAF and phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) mutations and primary tumor location remains unclear. METHODS: We prospectively collected tumor samples and clinical data of patients from 15 hospitals between August 2014 and April 2016 to investigate RAS, BRAF, and PIK3CA mutations using a polymerase chain reaction-based assay. According to the primary tumor location, patients were classified to right-sided (from cecum to splenic flexure) and left-sided (from descending colon to rectum) tumor groups. RESULTS: In total, 577 patients with CRC were investigated, 331 patients (57%) had CRC with wild-type RAS; of these 331 patients, 10.5%, 4.8%, and 5.9% patients harbored BRAFV600E, BRAFnon-V600E, and PIK3CA mutations, respectively. BRAF/PIK3CA mutations were more frequent in females, patients with right-sided tumors, and patients with peritoneal metastasis cases and less frequent in patients with liver metastases. The prevalence rates of BRAFV600E and PIK3CA mutations were higher in patients with right-sided tumors than in those with left-sided tumors (32.3% vs. 4.8% and 17.2% vs. 3.6%, respectively). CONCLUSIONS: More than half of the patients with right-sided CRC and wild-type RAS harbored BRAF/PIK3CA mutations, including BRAFnon-V600E, which may contribute to the difference in the anti-EGFR efficacy between the right- and left-sided CRC.

Annals of surgical oncology Vol. 27 ( 4 ) page： 1233 - 1240 2020.4

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

BACKGROUND: Squamous cell carcinoma antigen (SCC-Ag) and carcinoembryonic antigen (CEA) are widely used in clinical practice to predict the prognosis of patients with esophageal squamous cell carcinoma (ESCC). However, their predictive values for prognosis are controversial. This study determined optimal cutoff values of serum SCC-Ag and CEA concentrations for predicting postoperative recurrence of ESCC, which enabled selection of high-risk patients. METHODS: The study retrospectively analyzed 427 patients who underwent curative resection for ESCC. The optimal cutoff values of preoperative SCC-Ag and CEA concentrations for predicting postoperative recurrence were determined using combined analysis of hazard ratios and sensitivities for recurrence. Using the optimal cutoff value, the study evaluated survival, recurrence patterns, and temporal changes in marker concentrations. RESULTS: The preoperative SCC-Ag concentration of 1.1 ng/ml was the optimal cutoff value for predicting postoperative recurrence, whereas precise cutoff values could not be determined for preoperative CEA concentrations. High preoperative SCC-Ag concentrations (> 1.1 ng/ml), which were significantly associated with more aggressive tumor phenotypes and shorter disease-free survival, were identified as an independent prognostic factor in the multivariable analysis. High preoperative SCC-Ag concentrations were significantly associated with greater prevalence of lung/pleura and local recurrences. Normalization of serum SCC-Ag concentrations after neoadjuvant treatment or esophagectomy was not associated with a decreased risk of postoperative recurrence. CONCLUSIONS: The optimal cutoff value of preoperative SCC-Ag concentrations that predicted recurrence of ESCC was 1.1 ng/ml, illuminating the utility of serum SCC-Ag concentrations as an easily measurable tool for selecting a perioperative management strategy.

OBJECTIVE: This multicenter, single-arm phase II study (UMIN000008429) aimed to evaluate the efficacy and safety of capecitabine plus oxaliplatin (CapOX) as postoperative adjuvant chemotherapy for patients with locally advanced rectal cancer. METHODS: Patients with resectable clinical Stage II or III rectal cancer were enrolled to receive eight cycles of CapOX therapy (130 mg/m2 oxaliplatin on day 1 and 2000 mg/m2 oral capecitabine on days 1-14, every 3 weeks) after curative surgical resection. The primary endpoint was 3-year relapse-free survival (RFS) rate, and secondary endpoints were 3-year overall survival (OS) rate, treatment compliance, and safety. RESULTS: A total of 40 patients (Stage II, 21; Stage III, 19) were enrolled between September 2012 and November 2015 from seven institutions. Thirty-nine patients (97%) received R0 resection, and 32 patients (84%) received postoperative CapOX therapy. The completion rate of all eight cycles of CapOX therapy was 66%. Relative dose intensities were 87% for oxaliplatin and 84% for capecitabine. At a median follow-up period of 46 months, disease recurrence was observed in nine patients, including three with local recurrence. Three-year RFS and OS rates were 75% (95% CI 57-86%) and 96% (95% CI 80-99%), respectively. Frequencies of Grade ≥ 3 hematological and non-hematologic adverse events were 19% and 38%, respectively. CONCLUSION: CapOX therapy is feasible as adjuvant chemotherapy for locally advanced rectal cancer.

BACKGROUND/AIM: This retrospective study focused on the correlation between molecular markers and prognostic outcomes of colon cancer patients depending on sidedness. MATERIALS AND METHODS: A total of 117 stage I-III colon cancer patients who underwent colectomy were enrolled. Novel methylation markers (KIF1A, PAX5 and VGF) were selected for epigenetic evaluation and p53 and ERCC1 protein expression was examined for the investigation of genetic alterations. RESULTS: High frequency of methylation was observed in 68.2% of right-sided and 39.7% of left-sided colon cancer cases (p=0.004). Abnormal p53 was identified in 52.3% of right-sided and 75.3% of left-sided cases (p=0.015). In right-sided cases, highly methylated genes demonstrated significantly favorable disease-free survival (p=0.049). Regarding left-sided cases, advanced T stage (p=0.028) and abnormal p53 (p=0.028) were revealed to be significant predictive factors of the disease-free survival outcome. CONCLUSION: Molecular alterations, as significant prognostic factors, might differ depending on the sidedness of colon cancers.

Modified Systemic Inflammation Score is Useful for Risk Stratification After Radical Resection of Squamous Cell Carcinoma of the Esophagus. Reviewed International journal

Kanda M, Koike M, Tanaka C, Kobayashi D, Hattori N, Hayashi M, Yamada S, Omae K, Fujiwara M, Kodera Y

Annals of surgical oncology Vol. 26 ( 13 ) page： 4773 - 4781 2019.12

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

BACKGROUND: Inflammation plays a critical role in the development and progression of cancers. We evaluated the clinical significance of the preoperative modified systemic inflammation score (mSIS) to predict long-term outcomes of patients with esophageal squamous cell carcinoma (ESCC). METHODS: We included 443 patients who underwent curative resection of ESCC. The mSIS was formulated according to the serum albumin level (ALB) and lymphocyte-to-monocyte ratio (LMR) as follows: mSIS 0 (ALB ≥ 4.0 g/dL and LMR ≥ 3.4), mSIS 1 (ALB < 4.0 g/dL or LMR < 3.4), and mSIS 2 (ALB < 4.0 g/dL and LMR < 3.4). RESULTS: Patients were categorized into preoperative mSIS 0 (n = 165), mSIS 1 (n = 183), and mSIS 2 (n = 95) groups. Preoperative mSIS was significantly associated with age, preoperative body mass index, and pathological disease stage. The disease-specific survival times of patients in preoperative mSIS 0, 1, and 2 sequentially shortened (P = 0.009), and mSIS 2 was identified as an independent prognostic factor (hazard ratio 2.63, 95% confidence interval 1.33-5.27, P = 0.0053). In most patient subgroups, the mSIS was associated with greater risk of disease-specific death. A stepwise increase in the prevalence of hematogenous recurrences was directly proportion to the mSIS. When patients were subdivided by mSIS before neoadjuvant treatment, there were no significant differences in disease-specific survival. CONCLUSIONS: Our findings demonstrate that the preoperative mSIS may serve as a powerful prognosticator of ESCC that definitively stratifies clinical outcomes as well as a tool for selecting treatment strategies.

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

BACKGROUND/AIM: We previously reported that expression of melanoma-associated antigen (MAGE)-D4 mRNA was a prognostic factor for esophageal squamous cell carcinoma (ESCC). The aim of this study was to validate the expression of MAGE-D4 in two additional patient cohorts, and to investigate its biological functions. MATERIALS AND METHODS: The role of MAGE-D4 in cell proliferation, adhesion, and migration was determined by gene knockdown experiments in the KYSE590 cell line. MAGE-D4 protein expression was analyzed in ESCC tissues by immunohistochemistry. A second validation cohort consisted of an ESCC mRNA dataset from The Cancer Genome Atlas. RESULTS: Knockdown of MAGE-D4 significantly decreased cell proliferation and migration. Expression of MAGE-D4 protein was significantly associated with disease-free survival. In the second validation cohort, high MAGE-D4 mRNA expression was associated with significantly shorter overall survival and disease-free survival. CONCLUSION: MAGE-D4 plays an important role in the malignant behavior of ESCC. MAGE-D4 was validated as a prognostic indicator in two independent ESCC patient cohorts.

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

BACKGROUND: Gastric cancer (GC) exhibits heterogeneous clinical and molecular features, requiring the development of new biomarkers to further understand this disease. Our transcriptomic analysis detected overexpression of melanoma-associated antigen A6 (MAGEA6) in metastatic GC, leading us to determine the clinical significance of MAGEA6 in GC. MATERIALS AND METHODS: Fourteen GC cell lines and 230 pairs of surgically resected gastric tissues were subjected to mRNA expression analysis. Polymerase chain reaction array analysis was performed to identify coordinately expressed cancer-related genes, and immunohistochemistry (IHC) was used to detected MAGEA6 expression in situ. RESULTS: MAGEA6 mRNA levels were positively correlated with the expression of matrix metallopeptidase 9 mRNA. MAGEA6 mRNA levels were higher in GC tissues compared with those in normal adjacent tissues. Patients with high MAGEA6 expression had significantly worse prognosis. MAGEA6 protein levels in primary lesions predicted the likelihood of recurrence. CONCLUSION: Overexpression of MAGEA6 in GC tissues represents a promising biomarker for assessing the malignant phenotype of GC.

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

BACKGROUND: Identification of gastric cancer-related molecules is necessary to elucidate the pathological mechanisms of this heterogeneous disease. The purpose of this study was to identify novel genes associated with aggressive phenotypes of gastric cancer. METHODS: Global expression profiling was conducted using tissues from four patients with metastatic gastric cancer to identify genes overexpressed in gastric cancer. Fifteen gastric cell lines and 262 pairs of surgically resected gastric tissues were subjected to mRNA expression analysis. The contribution of the candidate gene on gastric cancer cell proliferation, invasion, adhesion, and migration were evaluated using small interfering RNA. RESULTS: DnaJ heat shock protein family (Hsp40) member C12 (DNAJC12) was identified as a candidate gene by transcriptome analysis. In clinical samples, DNAJC12 mRNA levels were higher in gastric cancer tissues compared with normal adjacent tissues. Patients with high DNAJC12 expression showed significantly shorter overall survival in our cohort and in the extra-validation cohort analyzed by a published microarray dataset. High DNAJC12 expression in gastric cancer tissues was significantly associated with lymphatic involvement, infiltrative growth type, lymph node metastasis, and advanced stage and was identified as an independent prognostic factor for overall survival in multivariable analysis. Increased expression of DNAJC12 was found in 12 of 14 examined gastric cancer cell lines. Knockdown of DNAJC12 expression significantly decreased the proliferation and invasion abilities of gastric cancer cells. CONCLUSIONS: Our findings support DNAJC12 as a candidate gene associated with aggressive phenotypes of gastric cancer.

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

BACKGROUND AND AIM: A reliable classification for predicting postoperative prognosis and perioperative risk of hepatocellular carcinoma (HCC) patients is required to make a precise decision for HCC treatment. In the present study, we assessed the perioperative and prognostic importance of indocyanine green (ICG) testing, tumor-node-metastasis (TNM) stage, albumin-bilirubin (ALBI) grade, and ALBI-TNM (ALBI-T) score using consecutive resected HCC cases. METHODS: Between 1998 and 2011, 273 consecutive patients who underwent primary and curative hepatectomy for HCC were identified. Among these 273 cases, 235 Child-Pugh class A patients were enrolled in the present study. RESULTS: Correlation analysis showed that the value of linear predictor for ALBI grade was significantly correlated with ICG 15-minute retention rates (r = 0.51, P < 0.0001). Survival analysis for both recurrence-free survival (RFS) and overall survival (OS) showed there were significant differences between the two groups stratified by stage or ALBI-T score (stage, RFS: P = 0.01, OS: P = 0.003; ALBI-T, RFS: P < 0.0001, OS: P < 0.0001). In addition, Cox proportional hazard model identified ALBI-T score was a significant predictor for both RFS and OS (RFS, P = 0.001; OS, P = 0.004). Furthermore, ALBI-T score could predict perioperative risk in hepatectomy such as longer operation time and excessive intraoperative blood loss. CONCLUSIONS: This study showed a robust association of ALBI-T score with postoperative HCC patient survival and perioperative risk in hepatectomy. ALBI-T score can be used as a simple and powerful tool for assessing HCC patients with further study.
