RESUMO

We present the case of a 35-year-old man with intractable nausea, vomiting, and severe anemia. A computed tomography (CT) scan of the chest, abdomen, and pelvis showed a circumferential lesion thickening of up to 3.5 cm at the level of the third portion of the duodenum. No aortocaval, retroperitoneal lymphadenopathy, nor secondary lesion was observed. Esophagogastroduodenoscopy (EGD) revealed a circumferential mass within the third portion of the duodenum. Histopathology of biopsy materials from the duodenal mass showed it most likely to be a poorly differentiated adenocarcinoma. The patient underwent a subtotal stomach-preserving pancreaticoduodenectomy with regional lymph node dissection. Histologically, tumor cells with basophilic cytoplasm and pleomorphic nuclei showed a solid pattern, and expressed CD30 and SALL4 immunohistochemically, leading to a diagnosis of embryonal carcinoma-like tumor. No other primary tumor could be identified, and the location of the tumor, mainly on the mucosal surface, suggested a duodenal origin. The UICC TNM staging was T3N2M0, stage IIB. This is a rare case of primary duodenal carcinoma with features of embryonal carcinoma.

RESUMO

Background: We investigated the impact of the age-adjusted Charlson comorbidity index (ACCI) on the pancreatic cancer survival and recurrence after curative surgery followed by adjuvant chemotherapy. Patients and Methods: This study included 155 patients who underwent curative surgery followed by adjuvant chemotherapy for pancreatic cancer between 2005 and 2014. The risk factors for the overall survival (OS) and recurrence-free survival (RFS) were identified. Results: An ACCI of 8 was regarded as the optimum critical point of classification considering the 1-, 3- and 5-year survival rates. The OS rates at 3 and 5 years after surgery were 25.7% and 19.0% in the ACCI-low group, respectively, and 7.6% and 0% in the ACCI-high group, which amounted to a statistically significant difference (P = 0.019). The RFS rates at 3 and 5 years after surgery were 17.3% and 13.8% in the ACCI-low group, respectively, and 7.1% and 0% in the ACCI-high group, which amounted to a marginally statistically significant difference (P = 0.104). A multivariate analysis showed that the ACCI was a significant independent risk factor for both the OS and RFS. Conclusions: The ACCI was a risk factor for the OS in patients who underwent curative surgery followed by adjuvant chemotherapy for pancreatic cancer. An effective plan is needed for determining the optimum surgical strategy according to the ACCI.

RESUMO

BACKGROUND: The short- and long-term outcomes of gastrectomy in elderly patients with gastric cancer have not been fully evaluated. PATIENTS AND METHODS: Patients who underwent gastrectomy were classified into two groups: Non-elderly patients (<80 years old) and elderly patients (≥80 years old). The surgical morbidity, overall and cancer-specific survival in the two groups were compared. RESULTS: A total of 411 patients were evaluated. The rate of overall complication was 29.4% in the non-elderly and 32.4% in the elderly (p=0.699). In the elderly, the overall and cancer-specific survival rates at 5 years after surgery were inferior to those of the younger group (59.8% vs. 66.7%, p=0.103 and 67.9% vs. 78.2%, p=0.028, respectively). CONCLUSION: The short-term outcomes after gastrectomy were almost equal for the two groups in the present study. The prognosis was poor in elderly patients, especially those with advanced gastric cancer.

RESUMO

BACKGROUND/AIM: We investigated the impact of the age-adjusted Charlson comorbidity index (ACCI) on esophageal cancer survival and recurrence after curative treatment. PATIENTS AND METHODS: This study included 122 patients who underwent curative surgery followed by adjuvant chemotherapy for esophageal cancer between 2005 and 2017. The risk factors for the overall survival (OS) and recurrence-free survival (RFS) were identified. RESULTS: An ACCI of 5 was regarded as the optimal critical point of classification considering the survival rates. The OS rates at 3 and 5 years after surgery were 64.2% and 54.4% in the low-ACCI group, respectively, and 42.3% and 29.2% in high-ACCI group, respectively (p=0.035). The RFS rates at 3 and 5 years after surgery were 50.2% and 43.6% in the low-ACCI group, respectively, and 28.5% and 21.3% in high-ACCI group, respectively (p=0.021). A multivariate analysis demonstrated that ACCI was a significant independent risk factor for both the OS and RFS. CONCLUSION: ACCI is a risk factor for survival in patients who undergo curative treatment for esophageal cancer. An effective plan for the perioperative care and surgical strategy should be developed according to ACCI.

RESUMO

BACKGROUND: Neuroendocrine carcinoma (NEC) originating from the extrahepatic bile duct (EHBD) is very rare but is known for its aggressiveness and poor prognosis. We herein report a case of rapidly progressed NEC in the extrahepatic bile duct. CASE PRESENTATION: An 84-year-old man was referred to our facility with obstructive jaundice and abdominal pain. Imaging studies revealed an irregular filling defect in the middle bile duct by endoscopic retrograde cholangiopancreatography and an enhanced wall thickening from the middle to distal portion by enhanced computed tomography. The patient was initially diagnosed with extrahepatic cholangiocarcinoma by a bile duct biopsy and underwent pancreatoduodenectomy with lymph node dissection. The pathological findings showed an NEC with an adenosquamous carcinoma component in the extrahepatic bile duct with lymph node metastases. The patient experienced multiple liver metastases 1 month after surgery and died 3 months after surgery. Due to the rapid progression of his disease, his general condition deteriorated, and he was unable to receive any additional treatments, such as chemotherapy. CONCLUSION: As shown in our case, NEC of the EHBD has an extremely poor prognosis and can sometimes progress rapidly. Multimodality treatment should be considered, even in cases of locoregional disease.

RESUMO

BACKGROUND/AIM: The aim of the present study was to evaluate the optimal number of harvested LNs (LNs) in patients who were LN metastasis-negative after curative esophagectomy for esophageal cancer. PATIENTS AND METHODS: Sixty-one patients who underwent curative surgery for esophageal cancer between 2005 and 2017 and diagnosed as lymph node metastasis-negative were included in this study. RESULTS: The 5-year overall survival rates were 27.8% for 0-20 harvested LNs, 35.7% for 21-30 harvested LNs, 79.4% for 31-40 harvested LNs, and 85.2% for ≥41 harvested LNs. Thirty harvested LNs was regarded as the optimal critical point of classification, considering the 5-year OS rate. The number of harvested LNs was selected as a significant prognostic factor in both univariate and multivariate analyses. The respective 3- and 5-year OS rates were 50.3% and 36.7% for <30 harvested LNs and 82.4% and 82.4% for ≥30 harvested LNs (p=0.003). CONCLUSION: Thirty or more harvested LNs was a significant prognostic factor in patients with metastasis-negative LNs after curative esophagectomy for esophageal cancer. Therefore, the number of harvested LNs might be useful for predicting the LN metastasis status in esophageal cancer.

RESUMO

BACKGROUND/AIM: We investigated the clinical impact of the lymph node ratio (LNR) on overall survival (OS) and recurrence-free survival (RFS) in esophageal cancer patients who underwent curative surgery. PATIENTS AND METHODS: One hundred twenty patients who underwent curative surgery for esophageal cancer between 2005 and 2017 were included in this study. The LNR was defined as the ratio of the number of metastatic lymph nodes (LNs) to the total number of harvested LNs. RESULTS: A lymph node ratio of 10% was regarded as the optimal critical point for classification based on the overall survival rate. The 3-year and 5-year OS rates were 65.5% and 57.0%, respectively, in the LNR<10% group, and 11.8% and 0% in the LNR≥10% group; the difference was statistically significant (p<0.001). The 3-year and 5-year RFS rates were 52.6% and 44.6%, respectively, in the LNR<10% group, and 0% and 0% in the LNR>10% group; the difference was also statistically significant (p<0.001). When comparing the sites of first relapse, the incidence of distant lymph node metastasis in the LNR>10% group was significantly higher than that in the LNR<10% group. CONCLUSION: The LNR was a risk factor for both OS and RFS in patients who underwent curative surgery for esophageal cancer.

RESUMO

BACKGROUND: Pancreatic cancer is a fatal disease with a poor prognosis. Pancreatic cancer is often unresectable at the time of diagnosis, so the analysis of risk factors in patients with indications for surgery is important. We investigated the impact of intraoperative blood loss (IBL) on survival and recurrence in patients with stage II/III pancreatic cancer after curative surgery. PATIENTS AND METHODS: This study included 76 patients who underwent curative surgery for stage II/III pancreatic cancer between 2007 and 2012. The risk factors for overall (OS) and recurrence-free (RFS) survival were identified. RESULTS: IBL of 1,000 ml was considered to be the optimal cut-off value for classification based on a receiver operating characteristic (ROC) curve analysis. The OS rates at 5 years after surgery in the groups with low and high IBL were 36.6% and 11.4%, respectively, which was a statistically significant difference (p=0.003). The RFS rates at 1 year after surgery were 49.8% and 24.6%, respectively, which was a significant difference (p=0.045). A multivariate analysis demonstrated that IBL was a significant independent risk factor for OS. CONCLUSION: IBL is an independent prognostic factor after curative resection of stage II/III pancreatic cancer. The reduction of bleeding during surgery is necessary to improve the results of pancreatic cancer surgery.

RESUMO

BACKGROUND: The aim of the present study was to evaluate the clinical impact of the perioperative use of antiplatelet/anticoagulation therapy for postoperative bleeding after esophagectomy for esophageal cancer. PATIENTS AND METHODS: Patients were selected from the medical records of consecutive patients who were diagnosed with primary esophageal adenocarcinoma or squamous cell carcinoma and who underwent complete resection at Yokohama City University from January 2005 to September 2018. The patients were divided into the antiplatelet/anticoagulation treatment group and the non-treatment group. We compared the safety and feasibility of esophagectomy between two groups. RESULTS: One hundred and twenty-two patients underwent esophagectomy for esophageal cancer and were analyzed in the present study. Among them, 18 (14.8%) received anti-thrombotic therapy (anticoagulation group). The incidence of postoperative bleeding in patients overall was 8.2% (10/122). The incidence of postoperative bleeding in the anticoagulation group was 22.2% (4/18), while that in the non-anticoagulation group was 5.8% (6/104). Preoperative anticoagulation therapy was identified as a significant independent risk factor for postoperative bleeding (hazard ratio=4.673, 95% confidence interval=1.170-18.519; p=0.029). CONCLUSION: The perioperative use of anti-thrombotic therapy was a significant risk factor for postoperative bleeding after esophagectomy for esophageal cancer. Thus, when patients receive perioperative antiplatelet/anticoagulation treatment, careful attention is required after esophagectomy due to their increased risk of postoperative bleeding.

RESUMO

BACKGROUND: Several immune-inflammatory markers are associated with cancer progression. The purpose of the present study was to clarify the influence of the preoperative C-reactive protein-to-albumin ratio (CRP/ALB ratio) on survival of patients with esophageal cancer and recurrence after curative resection. PATIENTS AND METHODS: The preoperative CRP/ALB ratio was evaluated in 122 patients who underwent radical resection for esophageal cancer from 2005 to 2018. The correlations between the CRP/ALB ratio and cancer-specific overall (OS), recurrence-free (RFS) survival and the clinicopathological status were analyzed. RESULTS: The optimal cut-off value of the CRP/ALB ratio determined using receiver operating characteristic curve analysis was 0.04. Patients were divided into two groups based on this cut-off value: the low CRP/ALB group (n=59) and the high CRP/ALB group (n=50). The OS rate at 5 years after surgery was significantly lower in the group with high CRP/ALB at 40.5% whilst it was 63.5% in the low CRP/ALB group (p=0.005). The corresponding RFS rates at 5 years after surgery were 32.5% and 48.3%, respectively, which was a statistically significant difference (p=0.007). A multivariate analysis showed that a high CRP/ALB ratio was a significant independent risk factor for poorer cancer-specific OS and RFS. CONCLUSION: The preoperative CRP/ALB ratio was a strong prognostic marker for patients with esophageal cancer. The surgical strategy, including procedure and perioperative care should be carefully planned for patients with a high CRP/ALB ratio.

RESUMO

BACKGROUND/AIM: Tumor microenvironments consist of many types of immune cells, in which regulatory T-cells (Tregs) are supposed to play important roles to suppress anti-tumor immunity. Regional lymph nodes are essential for antitumor immunity in colorectal cancer (CRC). In this study, we compared the diversity of phenotypes of T-cells in normal tissue and regional lymph nodes in order to determine the immunosuppressive mechanism of lymph node metastasis of CRC. PATIENTS AND METHODS: Fifty patients were enrolled in this study, and paired samples (tumor tissue, normal tissue, and three regional lymph node samples and as well as non-regional lymph node samples) were obtained from each patient. In each paired-sample set, the proportions of different immune cell types and T-cells expressing immune checkpoint molecules were compared using flow cytometry. RESULTS: Higher proportions of Tregs [7.58% (4.94%-13.87%) vs. 1.79% (0.03%-5.36%), p<0.001] and lower proportions of INFγ-producing CD4-positive T (iCD4+) cells [21.49% (12.08%-27.35%) vs. 26.55% (15.65%-37.63%), p<0.001] were observed in tumor tissue than in normal mucosa. Parts of regional lymph nodes nearest the tumor had a greater proportion of Tregs [5.86% (4.18%-7.69%)] and lower proportions of iCD4+ [5.94% (3.51%-9.04%)] and INFγ-producing CD8-positive T (iCD8+) cells [21.93% (14.92%-35.90%)] than distant parts of regional lymph nodes and non-regional lymph nodes. Both immune-suppressing molecules (CTLA-4 and PD-1) and immune-promoting molecules (OX-40 and ICOS) tended to be highly expressed in tumor tissue and local lymph nodes. CONCLUSION: In patients with CRC, regional lymph nodes, especially the parts nearest the tumor, had a higher proportion of Tregs and other suppressive immunophenotypes of T-cells than those located more distantly.

RESUMO

BACKGROUND/AIM: The present study aimed to identify risk factors for anastomosis leak (AL) after esophagectomy for esophageal cancer. PATIENTS AND METHODS: One-hundred twenty-two patients who underwent esophagectomy for esophageal cancer between 2008 and 2018 were included. The rate of AL was measured based on the definition of leak as adapted from the Surgical Infection Study Group. To identify the risk factors for AL, logistic regression analysis was used. RESULTS: AL was found in 44 of the 122 patients (36.1%). Among the factors examined, the lymph node dissection status (p=0.007) and preoperative serum albumin level (p=0.022) were significant independent risk factors for AL. The incidence of AL was 26.7% (20 of 75) among patients who received 2-field lymph node dissection and 51.1% (24 of 47) among those who received 3-field lymph node dissection. The incidence of AL was 29.9% (23 of 77) in the preoperative serum albumin levels ≥4.0 g/dl group and 46.7% (21 of 45) in the serum albumin levels <4.0 g/dl group. CONCLUSION: Lymph node dissection status and preoperative serum albumin levels were risk factors for AL in patients who received esophagectomy for esophageal cancer.

RESUMO

BACKGROUND: The short- and long-term outcomes of esophagectomy for esophageal cancer were fully evaluated in patients older than 75 years of age. PATIENTS AND METHODS: The present study selected patients who received esophagectomy for esophageal cancer. Patients were divided into non-elderly patients [age <75 years (non-elderly group)] and elderly patients [age ≥75 years (elderly group)]. The postoperative surgical morbidity, postoperative 30-days mortality, recurrence-free survival (RFS), and overall survival (OS) rates were evaluated between the non-elderly group and elderly group. RESULTS: One hundred twenty-two patients were evaluated in this study. Ninety-eight patients and 24 patients were classified into the non-elderly group and elderly group, respectively. The postoperative surgical complication rates in the non-elderly and elderly groups were 71.4% and 75.0%. There was not a statistically significant difference between the two groups (p=0.710). Mortality was observed in 1 patient in the elderly group (4.2%) due to cardiovascular disease. Significant differences were observed in the five-year OS and RFS rates of the elderly and non-elderly groups (55.4% vs. 29.7%, p=0.0017 and 42.2% vs. 21.2%, p=0.0334, respectively). CONCLUSION: Although the rate of postoperative surgical complications after esophagectomy for esophageal cancer was almost equal in the elderly and the non-elderly patients, significant differences were observed in the mortality and long-term outcomes of the two groups. Thus, the surgical strategy and perioperative care must be carefully planned for esophageal cancer patients older than 75 years of age.

RESUMO

BACKGROUND/AIM: To evaluate the outcomes of curative resection for Borrmann type IV gastric cancer through an analysis of the clinical, surgical and pathological data and through identifying which of these prognostic factors are associated with survival. PATIENTS AND METHODS: We retrospectively analyzed 2798 patients who had undergone excision of the primary lesion and 122 patients with type IV gastric cancer undergoing curative resection (R0 or 1) at Yokohama City University Hospital and Kanagawa Cancer Center between November 1995 and May 2016. RESULTS: Borrmann type IV gastric cancer had more advanced and unfavorable clinicopathological factors compared to other types. The 5-year overall survival rate was 28%, and the median survival was 21.8 months. The overall survival rate was influenced by the depth of invasion, lymph node metastasis, peritoneal lavage cytology (CY), stage and intraoperative blood loss. Of these, independent prognostic factors were intraoperative blood loss (<400 vs. ≥400 ml, risk ratio 1.64; p=0.045) and CY (0 vs. 1, risk ratio 2.25; p=0.004). CONCLUSION: The control of intraoperative bleeding had a positive impact on the survival of patients receiving curative resection for Borrmann type IV gastric cancer.

RESUMO

BACKGROUND: We investigated the clinical influence of anastomotic leak (AL) on esophageal cancer survival and recurrence after curative surgery. PATIENTS AND METHODS: This study included 122 patients who underwent curative surgery for esophageal cancer between 2008 and 2018. The patients were classified into those with AL and those without. The risk factors for overall (OS) and recurrence-free (RFS) survival were identified. RESULTS: AL was found in 44 out of the 122 patients (36.1%). The respective OS rates at 3 and 5 years after surgery were 43.9% and 40.2% in the AL group and 63.9% and 53.2% in the non-AL group, which were significantly different (p=0.0049). In contrast, the respective RFS rates at 3 and 5 years after surgery were 44.8% and 29.8%, and 44.9% and 42.4%, which were not significantly different (p=0.2306). A multivariate analysis showed that AL was a significant independent risk factor for both poorer OS and RFS in patients who underwent curative surgery for esophageal cancer. CONCLUSION: To improve survival of patients with esophageal cancer, the surgical procedure, perioperative care and surgical strategy must be carefully planned in order to prevent AL.

RESUMO

BACKGROUND: The C-reactive protein (CRP)-to-serum albumin ratio is associated with a poor prognosis in patients with several cancers. The purpose of this study was to clarify the relationship between the preoperative CRP/Alb ratio and overall survival of pancreatic ductal adenocarcinoma (PDAC) in patients who received radical surgery and S-1 adjuvant chemotherapy. PATIENTS AND METHODS: We included 117 patients who underwent radical surgery with S-1 adjuvant chemotherapy. We constructed receiver operating characteristic curve (ROC curve) of the CRP/Alb ratio to determine the cut-off value. We analyzed the relationship among the CRP/Alb ratio, clinicopathological status, and survival. RESULTS: The optimal cut-off value of the CRP/Alb ratio was 0.036. All patients were divided into a high-ratio group (CRP/Alb ratio ≥0.036) and low-ratio group (CRP/Alb ratio <0.036). The 5-year overall survival (OS) rates in the high- and low-ratio groups were 22.5% and 36.4%, respectively (p=0.0089). The 5-year disease-free survival (DFS) rates in the high- and low-ratio groups were 12.5% and 22.1%, respectively (p=0.0097). The univariate and multivariate analyses of the OS showed that the pathological N factor and CRP/Alb ratio were independent factors of the survival. The univariate and multivariate analyses of the RFS showed that the pathological N factor, resection margin, and CRP/Alb ratio were independent factors of the survival. CONCLUSION: The preoperative CRP/Alb ratio is a strong prognostic factor for PDAC patients with undergo curative resection with S-1 adjuvant chemotherapy.

RESUMO

Background: The aim of this study was to determine whether or not the short- and long-term outcomes were affected by the age-adjusted Charlson comorbidity index (ACCI) in patients who underwent curative resection for gastric cancer. Methods: The patients were retrospectively selected from among the medical records of consecutive patients who underwent curative gastrectomy with nodal dissection for gastric cancer at Yokohama City University and Kanagawa Cancer Center from January 2000 to August 2015. Results: A total of 2254 patients were eligible for inclusion in the present study. One thousand six hundred fifty-six patients had an ACCI of <6 points (ACCI low group), while 598 had a score of ≥6 points (ACCI high group). The median age (p<0.001) and American Society of Anesthesiologists physical status (ASA-PS) score (p<0.001) of the ACCI high group were higher in comparison to the ACCI low group. The incidence of surgical complications in the ACCI high group was significantly higher than that in the ACCI low group (12.0% vs. 7.2%, p<0.001). Univariate and multivariate analyses demonstrated that an ACCI high classification was a significant risk factor for postoperative complications. In addition, the 5-year OS rates of the ACCI low and ACCI high groups were 85.4% and 74.1%, respectively. The difference was statistically significant (p<0.001). The univariate and multivariate analyses demonstrated that an ACCI high classification was a significant prognostic factor for OS. Conclusions: Our results support that a high ACCI value is an independent risk factor for the short- and long-term outcomes of patients with gastric cancer. To improve the survival of patients with gastric cancer, it is necessary to carefully plan the perioperative care and the surgical strategy according to the ACCI.

RESUMO

BACKGROUND/AIM: We investigated the impact of Beppu's nomogram on colorectal liver metastasis in patients receiving perioperative chemotherapy and/or targeted therapy. PATIENTS AND METHODS: This study included 43 patients who underwent primary hepatic resection for colorectal liver metastasis at the Kanagawa Cancer Center from June 2006 to March 2011. The patients were classified as having a Beppu's nomogram score ≤9 (low-risk group) or ≥10 (high-risk group). The risk factors for the disease-free survival (DFS) were identified. RESULTS: The respective DFS rates at 1, 2, and 3 years after surgery were 72.0%, 43.3%, and 17.3% in the low-risk group and 27.8%, 16.7%, and 8.3% in the high-risk group, the difference being significant (p=0.009). The multivariate analysis showed that Beppu's nomogram score ≥10 was a significant independent risk factor for the DFS. CONCLUSION: Beppu's nomogram score was an independent prognostic factor for colorectal liver metastasis in patients receiving perioperative chemotherapy and/or targeted therapy. Thus, Beppu's nomogram might be a useful tool for predicting the risk of recurrence after hepatectomy, even in the era of newly-developed chemotherapy.

RESUMO

BACKGROUND/AIM: Postoperative pneumonia after esophageal cancer can lead to additional pain, prolonged hospital stay, and respiratory failure. These adverse events might lead to early recurrence and/or death. We investigated the influence of postoperative pneumonia on the esophageal cancer survival and recurrence after curative surgery. PATIENTS AND METHODS: This study included 122 patients who underwent curative surgery for esophageal cancer between 2008 and 2018. The patients were classified into: i) those with postoperative pneumonia (pneumonia group) and ii) those without postoperative pneumonia (non-pneumonia group). The risk factors for the overall survival (OS) and recurrence-free survival (RFS) were identified. The rate of postoperative pneumonia was measured by the revised Uniform Pneumonia Score. RESULTS: Postoperative complications were found in 34 of the 122 patients (27.9%). The OS rate at 5 years following surgery was 28.2% in the pneumonia group and 55.1% in the non-pneumonia group (p=0.006). The RFS rate at 5 years after surgery was 18.9% in the pneumonia group and 49.2% in the non-pneumonia group (p=0.061). A multivariate analysis showed that postoperative pneumonia was a significant independent risk factor for OS. CONCLUSION: The development of postoperative pneumonia was a risk factor for a decreased overall survival in patients who underwent curative surgery for esophageal cancer. The surgical procedure, perioperative care and surgical strategy should be carefully planned in order to avoid postoperative pneumonia.

RESUMO

Background: The predictive roles of secreted protein acidic and rich in cysteine (SPARC) in pancreatic ductal adenocarcinoma (PDAC) patients after curative resection have not been clarified. We investigated the correlations between the SPARC expression and the postoperative prognosis. Methods: We retrospectively analyzed the clinical data from consecutive patients who underwent curative resection for pancreatic cancer in our institution from 2005 to 2014. Stromal SPARC expression was analyzed by immunohistochemistry on tumor tissue microarrays (TMAs) from the patients. Results: A total of 179 patients were enrolled to this study. The median follow-up period of the present study was 62.1 months. Seventy patients had positive SPARC expression (39.1%). There were no significant differences between the positive SPARC-positive group and the SPARC-negative group. In the survival analysis, there was a significant difference between the SPARC-positive and SPARC-negative groups in the 5-year overall survival (OS) rates after surgery, which were 8.1% and 19.8%, respectively (p=0.0316). A univariate analysis showed that the SPARC expression, size of tumor, lymph node metastasis, and residual tumor were possible prognostic factors. A multivariate analysis showed that the SPARC expression (hazard ratio [HR]: 1.44, 95% confidence interval [CI]: 1.017-2.051), lymph node metastasis (HR: 2.019, 95% CI: 1.318-3.091), and residual tumor (HR: 1.648, 95% CI: 1.132-2.401) were independent prognostic factors. Conclusions: The stromal SPARC expression in resectable pancreatic cancer patients might be useful as a prognostic marker.
