RESUMEN
Given that esophageal cancer is highly malignant, the discovery of novel prognostic markers is eagerly awaited. We performed serological identification of antigens by recombinant cDNA expression cloning (SEREX) and identified SKI proto-oncogene protein and transmembrane p24 trafficking protein 5 (TMED5) as antigens recognized by serum IgG antibodies in patients with esophageal carcinoma. SKI and TMED5 proteins were expressed in Escherichia coli, purified by affinity chromatography, and used as antigens. The serum anti-SKI antibody (s-SKI-Ab) and anti-TMED5 antibody (s-TMED5-Ab) levels were significantly higher in 192 patients with esophageal carcinoma than in 96 healthy donors. The presence of s-SKI-Abs and s-TMED5-Abs in the patients' sera was confirmed by western blotting. Immunohistochemical staining showed that the TMED5 protein was highly expressed in the cytoplasm and nuclear compartments of the esophageal squamous cell carcinoma tissues, whereas the SKI protein was localized predominantly in the nuclei. Regarding the overall survival in 91 patients who underwent radical surgery, the s-SKI-Ab-positive and s-TMED5-Ab-negative statuses were significantly associated with a favorable prognosis. Additionally, the combination of s-SKI-Ab-positive and s-TMED5-Ab-negative cases showed an even clearer difference in overall survival as compared with that of s-SKI-Ab-negative and s-TMED5-Ab-positive cases. The s-SKI-Ab and s-TMED5-Ab biomarkers are useful for diagnosing esophageal carcinoma and distinguishing between favorable and poor prognoses.

BACKGROUND: RalA is a member of the Ras superfamily of small GTPases. The Anti-RalA autoantibodies (s-RalA-Abs) act as tumor markers in various types of cancer and are negatively associated with the p53 autoantibodies (s-p53-Abs). This study aimed to evaluate the relationship between s-RalA-Abs and s-p53-Abs in various types of cancer. METHODS: A total of 1833 cancer patients (esophageal cancer, 172; hepatocellular carcinoma, 91; lung cancer, 269; gastric cancer, 317; colon cancer, 262; breast cancer, 364; and prostate cancer, 358) and 73 healthy subjects were enrolled in the study. The levels of s-RalA-Abs and s-p53-Abs were analyzed using enzyme-linked immunosorbent assay, and the positivity rates and relations between the two autoantibodies were evaluated. The cutoff values for s-RalA abs and s-p53 abs were set as mean + 2 standard deviation and the values higher than the cutoff values were defined as positive. RESULTS: The titers in all cancer types were significantly higher than those in the controls (P < 0.01). The positivity rates for s-RalA-Abs ranged between 11.7 and 21.5%, and those for s-p53-Abs ranged between 12 and 28.5%. A combined assay of the two antibodies revealed positivity rates of 20.9 and 44.2%. In Stage 0/I/II tumors, the positivity rates of the combination of the two antibodies ranged between 21.5 and 42.3%. The two autoantibodies were complementary to each other in the prostate and breast cancers, but independent in other carcinomas. CONCLUSION: The combined use of s-RalA-Abs and s-p53-Abs tended to increase the positivity rate in all cancers, including Stage 0/I/II cancers.

PURPOSE: We evaluated the clinicopathological and prognostic significance of preoperative serum creatine kinase (CK) levels in gastric cancer. PATIENTS AND METHODS: The subjects of this retrospective study were 942 patients who underwent surgery without preoperative chemotherapy for gastric cancer (643 men and 299 women), excluding Stage IV gastric cancer, between January, 2001 and December, 2020. We set the cutoff values for CK according to gender, as 64 U/L for men and 57 U/L for women, and evaluated the clinicopathological, prognostic, and gender significance of low CK levels by multivariate analysis. RESULTS: Tumor depth was significantly associated with low serum CK levels (p < 0.001). The low CK group showed significantly worse overall survival than the high CK group (p = 0.01). The prognostic impact of low CK levels was evident only in men (p = 0.009). In women, low CK levels were not an independent risk factor for poor prognosis (p = 0.33). These prognostic impacts of low CK levels on overall survival and recurrence-free survival were similar. CONCLUSION: Low preoperative CK levels in men with gastric cancer were predictive of poor survival. These prognostic impacts of low CK levels were not evident in women.

BACKGROUND: Serum creatine kinase level has been reported to be a prognostic indicator in breast or lung cancers but no reports have been in esophageal cancer. We analyzed the prognostic significance of preoperative serum creatine kinase level in patients with esophageal carcinoma. METHODS: We evaluated the preoperative serum creatine kinase levels of 148 patients (118 male and 30 female) with esophageal squamous cell carcinoma. According to their median serum creatine kinase levels, we divided the patients into high and low serum creatine kinase groups. Univariate and multivariate analyses were used to evaluate the impact of serum creatine kinase level on the prognosis of the patients. RESULTS: The tumor depth (P < 0.01) and stage (P < 0.01) were significantly associated with serum creatine kinase levels. The prognosis was worse in the low serum creatine kinase group than in the high serum creatine kinase group (P = 0.02). In the subgroup analysis, although no survival difference was observed in the female patients between the groups (P = 0.171), the survival of low serum creatine kinase group was significantly worse than that of high creatine kinase group in the male patients (P = 0.001). Cox proportional hazard regression analysis revealed that nodal status (P = 0.019) and serum creatine kinase level (P = 0.047) were independent risk factors associated with overall survival in the male patients. CONCLUSIONS: Preoperative low serum creatine kinase level was useful in predicting overall survival in the male patients with esophageal squamous cell carcinoma.

BACKGROUND: Cofilin (CFL1, actin-binding protein) and ß-actin (ACTB) are key molecules in the polymerization and depolymerization of actin microfilaments. The levels of these antibodies were analyzed, and the clinicopathological significance in patients with esophageal carcinoma were evaluated. METHODS: The levels of anti-CFL1 and anti-ACTB antibodies were analyzed in serum samples of patients with esophageal carcinoma and of healthy donors. Eighty-seven cases underwent radical surgery and the clinicopathological characteristics and prognosis was examined. RESULTS: Serum anti-CFL1 antibody (s-CFL1-Ab) levels and anti-ACTB antibody (s-ACTB-Ab) levels were significantly higher in patients with esophageal carcinoma than in healthy donors. Following the receiver operating characteristic curve analysis between healthy donors and esophageal carcinoma, the sensitivity and specificity for serum anti-CFL1 antibody (s-CFL1-Ab) were 53.3% and 68.8%. The sensitivity and specificity for serum anti-ACTB antibody (s-ACTB-Ab) were 54.9% and 67.7%, respectively. Univariate and multivariate analysis showed that s-CFL1-Ab and s-ACTB-Ab levels were not associated with sex, age, tumor depth, lymph node metastasis, or anti-p53-antibody levels. s-ACTB-Ab levels but not s-CFL1-Ab levels significantly correlated with squamous cell carcinoma antigen. Neither s-CFL1-Ab nor s-ACTB-Ab levels alone were obviously related to overall survival. However, patients with low s-CFL1-Ab levels and high s-ACTB-Ab levels exhibited significantly more unfavorable prognoses than those with high s-CFL1-Ab and low s-ACTB-Ab levels. CONCLUSIONS: Serum levels of anti-CFL1 and anti-ACTB antibodies were significantly higher in patients with esophageal carcinoma than in healthy donors. A combination of low anti-CFL1 and high anti-ACTB antibodies is a poor prognostic factor in esophageal carcinoma.

BACKGROUND: Several recent studies suggest that serum anti-p53 antibodies (s-p53-Abs) may be combined with other markers to detect esophageal and colorectal cancer. In this study, we assessed the sensitivity and specificity of s-p53-Abs detection of a new electrochemiluminescence immunoassay (ECLIA; Elecsys anti-p53). METHODS: Elecsys anti-p53 assay was used to analyze the level of s-p53-Abs in blood sera from patients with esophageal or colorectal cancer taken before treatment. Control blood sera from healthy volunteers, patients with benign diseases, and patients with autoimmune diseases served as a reference. In addition, squamous cell carcinoma antigen (SCC-Ag) and cytokeratin 19 fragments (CYFRA21-1) were assessed in patients with esophageal cancer, and carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 were assessed in patients with colorectal cancer. RESULTS: Samples from 281 patients with esophageal cancer, 232 patients with colorectal cancer, and 532 controls were included in the study. The median value of s-p53-Abs in control samples was < 0.02 µg/mL (range < 0.02-29.2 µg/mL). Assuming 98% specificity, the cut-off value was determined as 0.05 µg/mL. s-p53-Abs were detected in 20% (57/281) of patients with esophageal cancer and 18% (42/232) of patients with colorectal cancer. In combination with SCC-Ag and CEA, respectively, s-p53-Abs detected 51% (144/281) of patients with esophageal and 53% (124/232) of patients with colorectal cancer. CONCLUSIONS: The new s-p53-Abs assay Elecsys anti-p53 was useful in detecting esophageal and colorectal cancers with high specificity. Adding s-p53-Abs to conventional markers significantly improved the overall detection rates.

PURPOSE: We evaluated the clinical impact of the carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) values at the time of recurrence in gastric cancer patients. METHODS: Among 790 patients with R0 resected gastric cancer without neoadjuvant therapy between 2004 and 2017, 89 recurrence cases were retrospectively evaluated. The clinical impact of CEA and CA19-9 values on recurrence sites and post-recurrent prognosis were evaluated using univariate and multivariate analyses. RESULTS: The positive rates of CEA and CA19-9 at recurrence were significantly higher than the preoperative positive rates (CEA, 56% vs 24%; CA19-9, 37% vs 15%). Although CA19-9-positive patients at recurrence exhibited a poor survival, the difference was not significant. The positive rates of CEA at liver or lymph node recurrence were significantly higher than the preoperative positive rates. The positive rate of CA19-9 at peritoneal recurrence was significantly higher than the preoperative positive rate. CA19-9-positive patients at recurrence exhibited worse prognosis than CA19-9-negative patients, although the difference was not significant. At lymph node recurrence, CA19-9-positive patients exhibited a significantly worse survival than CA19-9-negative patients. CONCLUSION: In recurrent gastric cancer, the positive status of CA19-9 at recurrence might have a negative prognostic impact after recurrence; particularly, in patients with lymph node recurrence.

We verified the significance of intestinal blood flow evaluation by indocyanine green(ICG)fluorescence during intracorporeal anastomosis in laparoscopic colectomy which was performed from July 2019 to December 2019 in our institute. For 11 cases of intracorporeal anastomosis, we examined the patient background, surgical results such as operation time and blood loss, evaluation of intraoperative ICG blood flow, and perioperative complications. In all cases, after the mesentery treatment in the abdominal cavity and before the intestinal incision, the blood flow of the planned anastomosis site was evaluated by ICG fluorescence observation. No cases were required to be changed the anastomosis site. The average operation time was 240 minutes and the average blood loss was 10 mL. There were no perioperative complications such as anastomotic leakage, stenosis, bleeding, nor wound infection. It was suggested that the intraoperative evaluation of ICG blood flow during intracorporeal anastomosis in laparoscopic colectomy may contribute to the suppression of complications such as anastomotic leakage.

There are few reports on laparoscopic stoma creation; we report here our experience with laparoscopic stoma creation. PATIENTS AND METHODS: Seven patients who underwent laparoscopic stoma creation between April 2019 and December 2019 were studied and their clinical outcome was evaluated retrospectively. Operation approach: We performed a colostomy in the transverse colon. At first, we insert a 12 mm first port into the site of stoma marking. And more, we insert three 5 mm ports on the opposite side of the first port. We remove the adhesions of the intestinal tract and create a colostomy. RESULT: We changed open method 2 cases out of 7 cases due to extensive adhesion. In laparoscopically, we had an operation time of 97 (42-130) minutes and a blood loss of 5(2-40) mL. We had no postoperative complications or stoma problems. CONCLUSION: Laparoscopic stoma creation was useful due to few postoperative complications and can be rapidly transferred to chemotherapy.

Some cancers are related to atherosclerotic diseases; therefore, these two types of disease may share some antibody biomarkers in common. To investigate this, a first screening of sera was performed from patients with esophageal squamous cell carcinoma (ESCC) or acute ischemic stroke (AIS) for serological identification of antigens using recombinant cDNA expression cloning (SEREX). The amplified luminescent proximity homogeneous assay-linked immunosorbent assay (AlphaLISA) method, which incorporates glutathione donor beads and anti-human IgG acceptor beads, was used to evaluate serum antibody levels. SEREX screening identified low-density lipoprotein receptor-related protein-associated protein 1 (LRPAP1) as a target antigen of serum IgG antibodies in the sera of patients with ESCC or AIS. Antigens, including recombinant glutathione S-transferase-fused LRPAP1 protein, were prepared to examine serum antibody levels. AlphaLISA revealed significantly higher antibody levels against the LRPAP1 protein in patients with solid cancers such as ESCC and colorectal carcinoma and some atherosclerosis-related diseases such as AIS and diabetes mellitus compared with healthy donors. Correlation analysis revealed that the elevated serum antibody levels against LRPAP1 were associated with smoking, a well-known risk factor for both cancer and atherosclerosis. Serum LRPAP1 antibody is therefore a common marker for the early diagnosis of some cancers and atherosclerotic diseases and may reflect diseases caused by habitual smoking.

BACKGROUND: The positive response and the clinical usefulness of 14 serum antibodies in patients with esophageal squamous cell carcinoma (ESCC) were examined in this study. The Cancer Genome Atlas (TCGA) was used to investigate the frequency of gene expressions, mutations, and amplification of these 14 antigens and also the possible effects of antibody induction. METHODS: Blood serum derived from 85 patients with ESCC was collected and analyzed for the 14 antibodies using ELISA. The prognosis between positive and negative antibodies were then compared. The antibody panel included LGALS1, HCA25a, HCC-22-5, and HSP70. RESULTS: Patient serum was positive for all antibodies, except VEGF, with the positive rates ranging from 1.18 to 10.59%. Positive rates for LGALS1, HCA25a, HCC-22-5, and HSP70 were > 10%. TCGA data revealed that all antigen-related genes had little or no mutation or amplification, and hence an increase in gene expression affected antibody induction. The positive results from the panel accounted for the positive rate comparable to the combination of CEA and SCC. No significant association was observed between the presence of antibodies and disease prognosis. CONCLUSIONS: The detection rates of LGALS1, HCA25a, HCC-22-5, and HSP70 were 10% higher in patients with ESCC. Gene overexpression may be involved in such antibody production. These four antibodies were applied as a panel in comparison with conventional tumor markers. Moreover, it was confirmed that the combination of this panel and the conventional tumor markers significantly improved the positive rate.

PURPOSE: To establish the clinicopathological importance of serum p53 autoantibody (s-p53-Ab) titrations in patients with gastric cancer. METHODS: Preoperative s-p53-Ab titers were analyzed in 448 gastric cancer patients between 2010 and 2017. Seropositive patients were divided into three groups based on their antibody titers: 1.31-10.0 U/mL (low group); 10.1-100 U/mL (medium group); and > 100 U/mL (high group). We evaluated the associations between the s-p53-Abs and clinicopathological factors, carcinoembryonic antigen (CEA) levels, and cancer antigen 19-9 (CA19-9) levels. Overall survival was analyzed by multivariate analyses. RESULTS: A total of 72 patients (16%) were positive for s-p53-Abs. The rate of positivity for s-p53-Abs + CEA + CA19-9 was significantly higher than that for CEA + CA19-9, even in stage I gastric cancers. Gender, tumor depth, lymphatic node metastases, and distant metastases were all significantly associated with the presence of s-p53-Abs; however, overall survival was not associated with the antibodies. The patients in the high titer group (> 100 U/mL) had a relatively worse survival than those in the other groups. CONCLUSIONS: Based on our findings, s-p53-Abs improve the overall rate of positivity for detecting gastric cancer, but the prognostic value of a high s-p53-Ab titer for predicting overall survival is limited.

Neoadjuvant chemotherapy has been performed for locally advanced colorectal cancer with invasion to other organs or lateral lymph node metastasis in to control local recurrence and distant metastasis. We evaluated the treatment results and the significance of surgery in 53 patients(36 rectal cancer cases and 17 sigmoid colon cancer cases)who underwent surgery after chemotherapy by XELOX plus bevacizumab for 3 months. As pretreatment diagnosis, 42 cases were T4b and 39 cases were lymph node positive. Combined resection was performed in 34 cases including 12 cases of total pelvic exenteration. Pathological diagnosis showed 27 cases of ypT4b and 34 cases of ypN0. Pathological curative resection was performed in 90.4%. Histological effect by chemotherapy was 31 cases in Grade(Gr)1a, 10 cases in Gr 1b, 8 cases in Gr 2, and 4 cases in Gr 3, respectively. The 5-year survival rate was 60.9% in Gr 1a or lower and 100% in Gr 1b or higher. Tumor markers( CEA and CA19-9)were reduced into normal range after neoadjuvant chemotherapy in all 4 patients with Gr 3. Pathological CR could not be predicted from clinical findings after neoadjuvant chemotherapy. It was suggested that neoadjuvant chemotherapy for locally advanced rectal cancer with invasion to other organs or lateral lymph node metastasis is useful for improving the prognosis, surgical resection is indispensable as a multidisciplinary treatment, and that the pathological therapeutic effect leads to prognosis prediction.

BACKGROUND: Studies investigating serum midkine (s-MK) concentrations have employed a polyclonal antibody enzyme-linked immunosorbent assay system (ELISA), because the targeted polyclonal antibody has low specificity. We used a newly developed monoclonal antibody ELISA to investigate the prognostic and diagnostic capabilities of s-MK in patients with esophageal squamous cell carcinoma. METHODS: Serum samples from 102 patients with esophageal squamous cell carcinoma were analyzed using a newly developed monoclonal antibody ELISA specifically developed to detect s-MK. s-MK cutoff value was set at 421 pg/mL (mean + 2 SD) based on data from healthy controls. Clinicopathological characteristics, including tumor stage and positivity rates for two conventional tumor markers, serum p53 (s-p53-Abs) antibodies and SCC-antigen, were evaluated to assess a possible correlation with s-MK. The prognostic capability of a high s-MK level was evaluated using univariate and multivariate methods. RESULTS: Overall positive rate for s-MK concentrations: 21%. Large tumors (> 50 mm) showed significantly higher concentrations than smaller specimens, but other clinicopathological factors were not associated with s-MK. A combination assay using SCC-antigen together with s-p53-Abs and s-MK clearly increased our capability to detect esophageal squamous cell carcinoma. Although the difference was not statistically significant (P = 0.310), the high s-MK group experienced worse overall survival than our low s-MK group. CONCLUSIONS: s-MK and conventional tumor marker combination increased our capability to detect esophageal squamous cell carcinoma. Although s-MK might be associated with esophageal squamous cell carcinoma progression, it was not an independent risk factor reducing patient survival. This study was registered as UMIN000014530.

PURPOSE: Several studies have evaluated the association between ABO blood group and the prognosis of various types of cancer; however, little is known about the relationship between ABO blood group and esophageal squamous cell carcinoma (SCC). We investigated how ABO blood group and clinicopathological characteristics are related to the survival of Japanese patients with esophageal SCC. METHODS: We reviewed the medical records of 181 patients who underwent surgery for esophageal SCC between June, 2004 and December, 2015 and analyzed the association between ABO blood group and clinicopathological factors. Clinicopathological factors were also evaluated by univariate and multivariate analyses for possible association with survival. RESULTS: The prevalence of each blood group was as follows: A, 35.5%; B, 22.4%; O, 32.8%; and AB, 8.2%. The 5-year overall survival of all patients was 37.1%. Patients with non-type B blood had significantly worse 5-year overall survival than those with type B blood (30.2 vs. 58.8%, P < 0.05). CONCLUSIONS: ABO blood groups were associated with the survival of Japanese patients with esophageal SCC. Patients with non-B blood groups had significantly worse overall survival than those with the B blood group.

Objectives The current carbohydrate antigen 125 (CA125) cutoff value demonstrated high specificity but low sensitivity. Therefore, we used new cutoff values to evaluate the clinical impact of perioperative CA125 in gastric cancer. Methods This study retrospectively analyzed 525 patients with gastric cancer (349 males and 176 females), of whom 445 patients underwent R0 resection and 80 patients underwent R1/R2 resection between 2011 and 2020. The receiver operating characteristic curve indicated preoperative and postoperative cutoff CA125 values of 15.7 IU/mL and 17.3 IU/mL, respectively, to predict overall survival. Furthermore, we analyzed changes in postoperative CA125 levels and evaluated their prognostic impact using multivariate analysis. Results The preoperative CA125-positive rate was 25%. Males, advanced TNM factors, and noncurative resection cases demonstrated significantly higher positive rates than the other group. The preoperative CA125-positive group exhibited a significantly higher noncurative resection rate than the preoperative CA125-negative group (32% versus 10%, P < 0.01). Preoperatively, CA125-positive status was an independent poor prognostic factor (P < 0.01), and at three months postoperatively, it tended to be a poor prognostic factor. Conclusions High preoperative CA125 (>15.7 IU/mL) was a significant predictor for noncurative resection and poor overall prognosis in gastric cancer. Furthermore, postoperative CA125-positive status three months postoperatively was also a potential predictor of recurrence and poor prognosis.
RESUMEN
PURPOSE: The lactate dehydrogenase-to-albumin ratio (LAR) has been reported as a potential prognostic biomarker in various cancers; however, only a few pieces of information have been reported on esophageal cancer. Therefore, this study aimed to evaluate the prognostic significance of preoperative LAR in patients with esophageal cancer. METHODS: This study included 236 patients (193 men and 43 women; mean age of 66 years [range, 41-83 years]) with esophageal cancer who underwent curative surgery between September 2008 and March 2020. A total of 107 patients underwent upfront surgery, and 129 patients received neoadjuvant treatment. Patients were assigned into two groups, high and low LAR, based on preoperative LAR using a cutoff value of 6.2. The clinicopathological and prognostic significance of preoperative LAR was evaluated in univariate and multivariate analyses. RESULTS: Patients with deep tumors and neoadjuvant treatment were significantly associated with high LAR (p <0.05). The high LAR group showed a significantly poorer prognosis than the low LAR group (p <0.01). The multivariate analysis for the overall survival showed that deep tumors, lymph node metastasis, and high LAR were independent poor prognostic factors (p <0.05). CONCLUSION: High LAR was a useful poor prognostic biomarker in patients with esophageal cancer.
RESUMEN
WD repeat-containing protein 1 (WDR1) regulates the cofilin 1 (CFL1) activity, promotes cytoskeleton remodeling, and thus, facilitates cell migration and invasion. A previous study reported that autoantibodies against CFL1 and ß-actin were useful biomarkers for diagnosing and predicting the prognosis of patients with esophageal carcinoma. Therefore, the present study aimed to evaluate the serum levels of anti-WDR1 antibodies (s-WDR1-Abs) combined with serum levels of anti-CFL1 antibodies (s-CFL1-Abs) in patients with esophageal carcinoma. Serum samples obtained from 192 patients with esophageal carcinoma and other solid cancers. And s-WDR1-Ab and s-CFL1-Ab titers were analyzed using the amplified luminescent proximity homogeneous assay-linked immunosorbent assay. Compared with those of healthy donors, the s-WDR1-Ab levels were significantly higher in the 192 patients with esophageal, whereas these were not significantly higher in the samples from patients with gastric, colorectal, lung, or breast cancer. In 91 patients treated with surgery, sex, tumor depth, lymph node metastasis, stage and C-reactive protein levels were significantly associated with overall survival, as determined using the log-rank test, whereas the squamous cell carcinoma antigen, p53 antibody and s-WDR1-Ab levels tended to be associated with a worse prognosis. Although no significant difference was observed in the survival between the positive and negative groups of s-WDR1-Abs or s-CFL1-Abs alone in the Kaplan-Meier test, the patients in the s-WDR1-Ab-positive and s-CFL1-Ab-negative groups exhibited a significantly poorer prognosis in the overall survival analysis. On the whole, the present study demonstrates that the combination of positive anti-WDR1 antibodies with negative anti-CFL1 antibodies in serum may be a poor prognostic factor for patients with esophageal carcinoma.
RESUMEN
PURPOSE: Hypercalcemia has been reported as a poor prognostic factor in malignant tumors. However, no report has shown the clinical impact of serum calcium levels on patients with esophageal cancer. We evaluated the prognostic impact of preoperative serum calcium levels on patients with esophageal cancer. METHODS: We evaluated 240 patients (197 men, 43 women; mean age, 66 years; age range, 34-85 years) with esophageal cancer who underwent radical surgery between September 2008 and December 2017. After assigning the patients to two groups (high calcium group, 8.8 mg/dL or more and low calcium group, 8.7 mg/dL or less), we compared the groups' overall survival and the clinicopathological features. The clinicopathological and prognostic significance of preoperative serum calcium levels were evaluated in a univariate and multivariate analysis. RESULTS: The patients with deep tumors showed low serum calcium levels significantly more frequently (P <0.05). The low calcium group showed a significantly worse prognosis than the high calcium group (P <0.05). However, low serum calcium level was not an independent poor prognostic factor. CONCLUSIONS: Preoperative low serum calcium levels were associated with advanced tumors. Low serum calcium might be associated with esophageal cancer progression.

The sensitivity and specificity of a new automated electrochemiluminescence immunoassay system, Elecsys® Anti-p53 (Elecsys), were compared with that of the conventional serum anti-p53 antibody (s-p53-Ab) enzyme-linked immunosorbent assay kit [MESACUP anti-p53 test (MESACUP)]. Elecsys and MESACUP were used to analyze the levels of s-p53-Abs in patients with esophageal, colorectal and breast cancer. A total of 532 controls and 288, 235 and 329 patients with esophageal, colorectal and breast cancer, respectively, were enrolled. Additionally, the sera of patients with benign diseases of the esophagus, colorectal system and breast, patients with autoimmune diseases and healthy volunteers were analyzed as controls. Sensitivity and specificity were compared between the two assay systems. Positive agreement rates were 58.7% in all samples, 71.2% in esophageal samples, 73.6% in colorectal samples and 35.1% in breast samples. Negative agreement rates for the different cancer types were ≥97.1% and the overall agreement rates were ≥92.3%. When the specificities of the two assays were aligned for all samples, Elecsys demonstrated higher sensitivities for all types of analyzed cancer together, as well as for esophageal, colorectal and breast cancer, respectively. Although positive concordance between the two assay systems was low in terms of specificity, Elecsys had a higher sensitivity than the MESACUP.
