RESUMO
BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers, and surgical resection is the only potentially curative approach. However, the rate of recurrence remains high, particularly within the first 6 months, and is associated with a poor prognosis. The present study evaluated the clinical characteristics and risk factors for early recurrence in pancreatic ductal adenocarcinoma (PDAC) patients who underwent curative resection, regardless of the use of neoadjuvant chemotherapy, to identify predictive factors associated with early recurrence and poor outcomes as well as to determine the optimal treatment strategy for patients at high risk of early recurrence after surgical resection. METHODS: Patients who underwent pancreatic resection for PDAC at our institution from 2013 to 2021 were included in this study. We investigated the clinicopathological features of patients in groups: those with recurrence within 6 months, recurrence between 6 and 12 months, and recurrence beyond 12 months or no recurrence. A logistic regression analysis identified covariates associated with early recurrence at 6 and 12 months. RESULTS: The study included 403 patients with a median follow-up of 25.7 months. Recurrence was observed in 279 patients, with 14.6% recurring within 6 months, 23.3% within 6-12 months, and 62% after 12 months or not at all. The preoperative CA19-9 level, modified Glasgow prognostic score (mGPS), and positive peritoneal cytology were significant risk factors for early recurrence within 6 months, while positive peritoneal cytology, lymph node metastasis, and the absence of adjuvant chemotherapy were significant risk factors for recurrence within 12 months. For patients who received preoperative chemotherapy or chemoradiotherapy, the preoperative CA19-9 level, mGPS, and positive peritoneal cytology were significant independent risk factors for early recurrence within 6 months, while positive peritoneal cytology, lymph node metastasis, and the absence of adjuvant chemotherapy were significant independent risk factors for recurrence within 12 months. The study concluded that the overall survival after surgical resection for potentially resectable PDAC worsened according to the number of risk factors present in the patient. CONCLUSIONS: We clarified that preoperative CA19-9, positive peritoneal cytology, and the lack of adjuvant chemotherapy were consistent predictors for early recurrence within 6 and 12 months. In addition, an increased number of risk factors affecting the patient was associated with a poorer overall survival after potentially curable resection. Calculating the number of risk factors for early recurrence may be an essential predictive factor when considering treatment strategies.

INTRODUCTION: Postoperative pancreatic fistula (POPF) is one of the major critical complications after pancreatic resection. Recently, postoperative acute pancreatitis (POAP), a new concept for a pancreatic-specific complication following pancreatic resection, has been advocated, and its association with POPF has been reported. The present study examined the clinical features of POAP and identified the associations of POAP with POPF and other postoperative morbidities in pancreatic ductal adenocarcinoma (PDAC) patients undergoing pancreatic resection. METHODS: A total of 312 consecutive patients who underwent pancreatic resection for PDAC at our institution from 2013 to 2019 were enrolled in this study. POAP was defined as an elevated serum amylase level above the upper limit normal on postoperative day (POD) 0 or 1, based on Connor's definition. The severity of POPF was assessed by the International Study Group on Pancreatic Surgery definition. RESULTS: A total of 184 patients (58.9%) had POAP. POAP occurred in 58.5% of subtotal stomach-preserving pancreatoduodenectomy patients and 60% of distal pancreatectomy combined with splenectomy patients. The presence of POAP was significantly associated with the development of clinically relevant POPF, higher rates of severe morbidity, and a prolonged hospital stay after pancreatic resection. A multivariate analysis showed that the presence of POAP and elevated C-reactive protein levels on POD 3 were independent predictors of clinically relevant POPF after subtotal stomach-preserving pancreatoduodenectomy. CONCLUSIONS: POAP is associated with the development of POPF, higher rates of severe morbidity, and a prolonged hospital stay after pancreatic resection and is an independent risk factor for clinically relevant POPF after pancreatoduodenectomy. POAP represents an important indicator for planning treatment strategies to prevent serious complications, including POPF.

Perforated gastric cancer reported to be relatively rare and to have a poor prognosis. This study examined 9 patients with perforated gastric cancer. Two-thirds of the patients were male and the median age was 69 years. The timing of the diagnosis of gastric cancer was preoperative clinical findings in 4 cases, intraoperative surgical findings in 3 cases, and postoperative examination in 2 cases. The depths of tumor invasion were T3 in 3 cases, T4a in 4 cases, and T4b in 2 cases and 5 patients were Stage â £. Four patients underwent palliative gastrectomy and only 1 patient underwent curative(R0)gastrectomy. Four patients underwent repair surgery, 2 of which underwent omental patch repair during the initial surgery. One of patients with omental patch repair received 2-stage curative gastrectomy; the other patient received chemotherapy after recovering from acute peritonitis. The median overall survival was 17.9 months and the prognosis was favorable in cases with curative resection or chemotherapy. For patients with perforated gastric cancer, if curative resection cannot be expected, the initial surgery should be directed toward the treatment of peritonitis and radical oncological surgery or systemic chemotherapy should be planned following patient recovery.

Only a few studies have been conducted regarding the palliative radiation therapy(RT)for gastric cancer(GC)bleeding. Data of 9 patients with gastric cancer requiring blood transfusions due to gastric bleeding who were treated with RT were reviewed. All patients were men with a median age of 83(range, 70-91)years. The clinical stage was â ¡B in 2 patients, â ¢in 1, â £A in 1, and â £B in 5. Performing gastrectomy was difficult in 4 patients with distant metastasis or tumor invasion to adjacent organ, 3 with poor performance status, and 2 with advanced age. The median hemoglobin levels before RT was 6.0 (range, 3.3-7.7)g/dL, and all patients received blood transfusions before RT. Seven patients received 30 Gy RT and 2 patients received 50 Gy. Two patients received concurrent chemotherapy. A total of 2 hematological and 4 non-hematological treatment-related adverse events occurred. All patients improved conservatively. Hemorrhage occurred in 8 patients, except for 1. Of the 8 patients who responded to RT, 1 had rebleeding on day 81. The median rebleeding-free survival time from the beginning of RT was 125(range, 21-421)days. Palliative radiation therapy was useful for bleeding control in nonresectable gastric cancer.

Laparoscopic-assisted total gastrectomy(LATG)has several complications early during the introduction of the procedure, so a careful approach is necessary. In this study, we evaluated short-term outcomes after LATG at our hospital. From 2014 to 2017, 21 patients underwent LATG using ENDO-PSI. A 6-cm midline incision was made at the epigastrium, and the abdominal esophagus was transected using ENDO-PSI. The anvil head was fixed with extracorporeal ligation, and an end loop was added to the proximal side of the first suture. Reconstruction was performed with the Roux-en-Y method. The jejunojejunal anastomosis was performed extracorporeally, and esophagojejunostomy was performed using a circular stapler through the small incision. There were 15 men and 6 women, with a mean age of 74 years. The mean operation time was 296 min, and volume of blood loss was 75 mL. The median fasting period was 3(3-10)days, and the postoperative hospitalization period was 12(8-28)days. The postoperative complications were Grade â ¡ in 4 patients and Grade â ¢ in 1 patient. The complication due to esophagojejunostomy was anastomotic leakage in 1 patient, while no anastomotic stenosis was found. LATG using ENDO-PSI can be safely performed.

The aim of this study was to compare the outcome of using trans-anal ileus tube and self-expandable metallic stent(SEMS) for obstructive colorectal cancer. METHODS: Between 2014 and 2018, 14 patients received trans-anal ileus tube placement (group I)and 34 received SEMS insertion as bridge to surgery(BTS)and underwent primary resection. RESULTS: The technical success rate was 100%in both groups, and the clinical success rate was 85.7%(12/14 cases)in group I and 91.2%(31/34 cases)in group S. In group S, the CROSS score significantly improved, the rates of stoma construction and postoperative complications were significantly lower, and the period until oral intake and hospital discharge was significantly short. CONCLUSION: SEMS insertion is more effective than trans-anal ileus tube placement in terms of short-term outcome.

In elderly patients, surgical procesure is decided considering the general condition and surgical invasion. The aim of this study was to clarify the appropriate rage of lymph node dissection for elderly colorectal cancer patients. One hundred forty one colorectal cancer patients aged 75 years or more, who underwent R0 colorectal resection with D2 or D3 lymph node dissection in clinical T3/T4 or clinical N+, were enrolled in this study. The patients whose tumor located in the rectum below the peritoneal reflection(Rb)were excluded. Five-year overall survival(OS)rate and disease specific survival(DSS)rate were 79.1% and 89.4%, respectively. More than 2 preoperative co-morbidities and macroscopic type 3-5 were independent prognostic factors in OS, whereas the rage of lymph node dissection was not risk factor. When comparing the outcomes of D2 and D3 dissections by age, D3 dissection was better tendency in DSS in patients aged under 80, however, D2 dissection was better tendency in patients aged 80 or more. In elderly colorectal cancer patients, there was no difference in prognosis between D2 and D3 dissection, and especially in patients aged 80 years or more, D2 might be sufficient if R0 resection was possible.

BACKGROUND/AIM: The prognostic nutritional index (PNI) is used as a marker to evaluate the nutritional and immunological status of patients with various cancers. This study aimed to investigate whether preoperative PNI is a prognostic factor in patients with pancreatic cancer who underwent perioperative adjuvant chemotherapy and surgical resection. PATIENTS AND METHODS: We retrospectively enrolled 232 pancreatic cancer patients who underwent surgical resection with perioperative adjuvant chemotherapy between January 2013 and December 2022. Overall survival (OS) and relapse-free survival (RFS) rates were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed using the Cox proportional hazards regression models. RESULTS: The optimal cutoff value for the preoperative PNI was 44.3 in the present study. PNI <44.3 was associated with older age (p<0.001) and affected the clinical course of postoperative adjuvant chemotherapy. The PNI <44.3 had an important influence on the decreased OS (25.1 vs. 39.0 months) and RFS (13.1 vs. 22.8 months). In univariate and multivariate analyses, the preoperative PNI was an independent prognostic factor for OS [hazard ratio (HR)=1.682, 95% confidence interval (CI)=1.059-2.673, p=0.028] and RFS (HR=1.559, 95% CI=1.037-2.344, p=0.033). CONCLUSION: Preoperative PNI is a prognostic factor for both OS and RFS in patients with pancreatic cancer who underwent perioperative adjuvant chemotherapy and surgical resection. This study suggests that a low PNI may cause a lack of full-dose adjuvant chemotherapy, leading to recurrence and resulting in a poor prognosis for surgical pancreatic cancer patients treated with perioperative adjuvant chemotherapy.

BACKGROUND: Intraductal oncocytic papillary neoplasm (IOPN), previously classified as a subtype of intraductal papillary mucinous neoplasm (IPMN), has been described as an independent disease by the WHO since 2019. IOPN is a rare tumor, with few reported cases. Herein, we report a case of resected non-invasive IOPN that formed a lesion protruding toward the duodenum from the accessory papilla. CASE PRESENTATION: An 80-year-old woman was referred to our hospital because of a giant mass in the pancreatic head detected on abdominal contrast-enhanced computed tomography (CT) performed for a close examination of a mass in the right breast. CT revealed a 90-mm-sized tumor with a mixture of solid and cystic components, with contrast enhancement in the pancreatic head, and a dilated main pancreatic duct. Esophagogastroduodenoscopy revealed a semi-circumferential papillary tumor protruding toward the duodenal lumen, which did not protrude from the papilla of Vater. Transpapillary biopsy led to a preoperative diagnosis of IPMN with an associated invasive carcinoma. As there were no distant metastasis, open subtotal stomach-preserving pancreaticoduodenectomy was performed. Analysis of the surgical specimen and histopathological examination revealed that the tumor was an IOPN that protruded toward the duodenal mucosa from the accessory papilla while replacing the duodenal mucosa with no obvious stromal invasion. CONCLUSION: IOPN is a rare and poorly recognized tumor with few reported cases. There have been no reports describing IOPN forming a protruding lesion toward the duodenum from the accessory papilla. Therefore, further accumulation of cases such as this one is important to advance the study of IOPN.
RESUMO
BACKGROUND/AIM: The prognosis of patients with pancreatic cancer remains poor, despite recent advances in surgical techniques, perioperative care, neoadjuvant and adjuvant chemotherapy. This study aimed to investigate the preoperative neutrophil-to-lymphocyte ratio (NLR) as a prognostic factor and determine the optimal cutoff value in surgical patients with pancreatic cancer. PATIENTS AND METHODS: We retrospectively enrolled 461 patients with pancreatic cancer who underwent resection between January 2013 and December 2022 in the Department of Gastrointestinal Surgery at Kanagawa Cancer Center. The association between continuous or categorical variables and NLR was analyzed using the Mann-Whitney U-test and Fisher's exact test. Overall survival (OS) and relapse-free survival (RFS) rates were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed using Cox proportional-hazard regression models. RESULTS: The optimal cutoff value for the preoperative NLR was 3.2. The NLR≥3.2 was associated with a large tumor size (p=0.005), poor histological differentiation (p=0.002), and less adjuvant chemotherapy (p=0.048). The NLR≥3.2 had an important influence on the decreased OS (21.6 vs. 25.8 months), and RFS (10.3 vs. 14.3 months). In univariate and multivariate analyses, the preoperative NLR was an independent prognostic factor for OS (p=0.022) and RFS (p=0.002). CONCLUSION: Preoperative NLR (cutoff value: 3.2) within two weeks before surgery is a prognostic factor for OS and RFS in surgical patients with pancreatic cancer. This study could help establish evidence on the immune system's impact and a unified treatment strategy pre-surgery, potentially improving the prognosis for patients with pancreatic cancer.

BACKGROUND/AIM: The standard treatment for resectable pancreatic cancer is preoperative adjuvant chemotherapy (NAC) + curative surgery + adjuvant chemotherapy. Although excellent local control results of carbon ion radiotherapy (CIRT) for pancreatic cancer have been reported, no reports have compared CIRT with the standard treatment for resectable pancreatic cancer. In this study, we compared the results of CIRT for resectable pancreatic cancer with those of standard therapy and investigated the usefulness of CIRT. PATIENTS AND METHODS: The subjects were 35 patients who underwent CIRT for clinical cT1-2, N0-1, and M0 cancers at Kanagawa Cancer Center, Yokohama, Japan, from September 2018 to September 2021, and 110 patients who underwent standard treatment (NAC + curative surgery + adjuvant). Overall survival (OS) and recurrence-free survival (PFS) were compared between the two groups using propensity score-matching (PSM). RESULTS: Twenty-three CIRT monotherapy patients were matched with NAC + curative surgery + adjuvant chemotherapy patients by PSM. Although there was no significant difference in RFS between the two groups, OS was significantly poorer in the CIRT monotherapy group than in the NAC + curative surgery + adjuvant chemotherapy group. CONCLUSION: This single-centre retrospective propensity score-matched comparison of CIRT and NAC + curative resection + adjuvant chemotherapy as the standard therapy for resectable pancreatic cancer showed an inferiority of CIRT in terms of OS, but no difference in PFS. Therefore, CIRT monotherapy may be a treatment strategy for patients with contraindications for standard treatment of curative surgery plus perioperative chemotherapy.

BACKGROUND/AIM: Pancreatic cancer has the highest risk of venous thromboembolism (VTE). Additionally, chemotherapy for cancer patients increases the risk of developing VTE. Due to recent advances in neoadjuvant chemotherapy (NAC) regimens, more patients with resectable pancreatic cancer will receive NAC. However, the incidence, risk, and predictors of developing VTE in these patients have not been fully evaluated. PATIENTS AND METHODS: We retrospectively evaluated the incidence, risk, and predictors of VTE among 67 consecutive patients with resectable pancreatic cancer who received neoadjuvant combination therapy with gemcitabine+S-1 (NAC-GS) followed by surgery and 45 patients with resectable pancreatic cancer who underwent upfront surgery (Up-S). RESULTS: The incidence of VTE in the NAC-GS and Up-S groups was 10.4% and 6.6%, respectively. Preoperative D-dimer levels were significantly higher in the NAC-GS group, and D-dimer levels were significantly increased during NAC-GS. Preoperative D-dimer level was the only predictor for VTE in patients with resectable pancreatic cancer who received NAC-GS. CONCLUSION: There is an increased risk of developing VTE during NAC. Screening with D-dimer and taking appropriate measures to suppress critical VTE is essential to provide NAC to patients with resectable pancreatic cancer.

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: 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.

OBJECTIVE: To investigate the prognostic values of the preoperative modified Glasgow Prognostic Score (mGPS) and carcinoembryonic antigen (CEA) alone and combined in elderly patients with colorectal cancer (CRC) planning to receive curative surgery. METHODS: We retrospectively analyzed 130 elderly patients (aged ≥80 years) with CRC who received curative surgery between 2008 and 2016. The preoperative mGPS and CEA levels were calculated. RESULTS: Elevated preoperative mGPS or CEA level was significantly associated with shorter relapse-free survival (p = 0.005, both) and cancer-specific survival (p = 0.011 and p < 0.001, respectively). Combined use of these two factors improved the predictive accuracy for tumor recurrence relative to that of either factor. CONCLUSION: Both mGPS and CEA were independent prognostic factors of CRC in elderly patients receiving curative surgery, but their combination was more accurate.

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.
