RESUMEN

BACKGROUND: Thrombomodulin is a thrombin receptor on the endothelial cell surface that plays an important role in the regulation of intravascular coagulation. The purpose of this study was to evaluate the efficacy and safety of treatment with recombinant human soluble thrombomodulin (rhTM) for patients with septic-disseminated intravascular coagulation (DIC) associated with gastroenterological surgery. MATERIALS AND METHODS: From April 2011-September 2013, 201 patients with DIC associated with gastroenterological surgery were treated in 16 institutions in Kumamoto, Japan. The patients were diagnosed according to the Japanese Association for Acute Medicine DIC scoring system. The clinical course, mortality rate at 28 d, and adverse events were evaluated retrospectively. RESULTS: Forty-five patients were excluded because they did not meet the Japanese Association for Acute Medicine DIC criteria or had an insufficient duration of drug administration. Thus, 156 patients were analyzed. Of these patients, 107 received rhTM at the discretion of the attending surgeon and 49 did not. The most common reason for surgery in both groups was peritonitis due to perforation of the colon. Within 7 d, the platelet count, prothrombin time-international normalized ratio, DIC score, neutrophil count, and C-reactive protein level significantly improved in the rhTM group compared with those in the control. Treatment with rhTM was significantly associated with reduced inhospital mortality at 28 d. The incidence of adverse events did not differ between the two groups. CONCLUSIONS: Therapy with rhTM may be associated with reduced inhospital mortality in patients with septic DIC associated with gastroenterological surgery without increasing adverse events.

RESUMEN

A 55-year-old woman consulted our hospital complaining of abdominal distention and vomiting. She was diagnosed with a malignant tumor in the small intestine and an ovarian tumor with an upper gastro-intestinal series based on a computerized tomography(CT)examination. Intra-operative findings showed that the primary tumor was located in the proximal jejunum, 10 cm on the anal side from Treitz's ligament. There were no liver metastases, but the tumor had spread into the peritoneal cavity(light ovary). The jejunum and light ovary were therefore resected. Pathological diagnosis of the resected specimen revealed adenocarcinoma with lymph node metastases(T4N1M1, UICC StageIV). The patient received systemic chemotherapy with oral S-1. A recurrent lesion on the right ovary was detected 6 months after surgery. The patient subsequently underwent resection of the right ovary. For lung metastases and recurrent peritoneal dissemination, combination chemotherapy with XELOX or FOLFIRI, along with capecitabine plus bevacizumab, and cetuximab, was administered. The patient died 33 months after the first surgery. Primary small intestinal adenocarcinoma is a rare disease, and it is often diagnosed at an advanced stage because there are very few characteristic symptoms. This case may be an important case for the development of a standard chemotherapy regimen for advanced and recurrent adenocarcinoma of the small intestine.

RESUMEN

BACKGROUND: Several previous studies have revealed that the Glasgow Prognostic Score (GPS) is a clinically useful scoring system to predict the prognosis of patients with various kinds of advanced cancers. However, there have been few reports on the relationship between the GPS and prognosis after hepatectomy for hepatocellular carcinoma (HCC). Therefore, we performed an analysis of the relationship between the GPS and prognosis after hepatectomy for HCC. METHODS: Between January 2005 and December 2009, 352 HCC patients underwent hepatectomy at Kumamoto University Hospital. Nineteen clinicopathologic factors were analyzed, using univariate and multivariate analyses. RESULTS: Univariate analysis showed that significant risk factors for poor survival included serum albumin level (<3.5 g/dL), tumor size (>35 mm), presence of ascites, portal vein invasion, operation time (>400 min), blood loss (>360 mL), requirement for blood transfusion, and GPS. Multivariate analysis revealed that tumor size [hazard ratio (HR) 3.355; p = 0.003], operation time (HR 2.634; p = 0.006), portal vein invasion (HR 2.419; p = 0.009), and GPS (HR 3.796; p < 0.001) were independent factors for poor prognosis. CONCLUSION: The GPS was demonstrated to be a statistically significant prognostic factor after hepatectomy for HCC.

RESUMEN

Tumor lysis syndrome (TLS) is the rapid disintegration of a malignant tumor treated with anticancer drugs or radiation, causing electrolyte abnormalities such as elevated uric acid levels, elevated potassium and phosphorus levels, and decreased calcium levels. These abnormalities can lead to hypotension, renal dysfunction, consciousness disorders, and even death in some cases. The current patient was a 65-year-old woman who had breast cancer with local invasion, lung metastasis, and bone metastasis from the time of the initial disease onset. Despite the administration of various chemotherapy and hormone therapy regimens, the tumor increased gradually, and at 2 years and 5 months after the initial onset, pain and bleeding from metastatic infiltration of the cervical lymph nodes were noted. Therefore, radiotherapy was indicated for palliation of pain and bleeding caused by metastatic invasion of the cervical lymph nodes. Irradiation (30 Gy/10fr) was planned with a 3-field technique using 4MVX and 10MVX. Approximately 11 h after the initial irradiation, symptoms such as respiratory distress, tachycardia, and hypotension were observed. Blood tests revealed hyperuricemia and hyperkalemia, leading to a diagnosis of TLS. Dialysis and electrolyte correction were immediately initiated resulting in normalization of electrolytes and stabilization of the blood pressure. It is crucial to understand that TLS is relatively rare but can occur after radiation therapy or in solid tumors, and warrants a prompt response if suspected based on symptoms or blood findings.

RESUMEN

BACKGROUND: The mechanisms of IPMN carcinogenesis are as yet unclear. This study aimed to determine whether expression of EZH2 promotes neoplastic progression of IPMN and PDCA, and to elucidate regulation of EZH2 expression by miR-101. METHODS: EZH2 mRNA and protein expression were investigated in 8 human pancreatic cancer cell lines by PCR and western blotting. Pre-miR-101 and anti-miR-101 were transfected into pancreatic cancer cells to elucidate EZH2 regulation by miR-101. To evaluate whether EZH2 modulates malignant progression of IPMN, EZH2 expression in IPMN was examined by immunohistochemistry. Next, we collected malignant and benign cells from FFPE samples of IPMNs using laser capture microdissection and extracted the RNA. miR-101 expression in IPMN was assessed using real-time PCR. RESULTS: All pancreatic cancer cell lines expressed EZH2 mRNA and protein. The induction of miR-101 by transfection of pre-miR-101 in MIA PaCa-2 was closely related to a reduction in EZH2 protein production compared with control, whereas there was little difference in the expression of EZH2 mRNA. Anti-miR-101 transfected pancreatic cancer cells showed an increase in EZH2 protein, while the level of EZH2 mRNA was not elevated. Immunohistochemistry revealed that the expression of EZH2 was significantly higher in malignant than benign IPMN. Expression of miR-101 was significantly lower in malignant IPMN than benign IPMN. CONCLUSIONS: MiR-101 targets EZH2 at the posttranscriptional level, and loss of miR-101 could be a trigger for the adenomacarcinoma sequence of IPMN by upregulation of EZH2. This study suggests miR-101-EZH2 blockade as a potential therapeutic target in IPMN carcinogenesis.

RESUMEN

BACKGROUND/AIMS: The correlation between the mass-forming type of intrahepatic cholangiocarcinoma (ICC) and the infection of the hepatitis B virus and hepatitis C virus are poorly understood. In this study, the clinical features of 34 patients with the mass-forming type ICC were reviewed to evaluate prognostic determinants. METHODOLOGY: Between January 1997 and December 2007, 34 patients underwent surgical resection for the mass-forming type of ICC in Kumamoto University Hospital. The significance of 14 clinicopathological factors consisting of age, gender, CA19-9 levels, CEA levels, size, intrahepatic metastases, portal vein invasion, bile duct invasion, histological differentiation, lymph node involvement, type B or C hepatitis, lymph node dissection, Sirius Red score of the tumor and platelet count in peripheral blood were analyzed, with regard to prognostic aspect. RESULTS: Univariate analysis showed that significant risk factors for poor survival included age =65 years, CEA levels =1.6ng/mL and pathological lymph node involvement. Multivariate analysis revealed that age, CEA levels and lymph node involvement were independent and significant poor prognostic factors. CONCLUSIONS: It was concluded that age, CEA levels and lymph node involvement were significantly poor prognostic factors. However, the infection with type B or C hepatitis was not a prognostic factor of the mass forming type ICC.

RESUMEN

BACKGROUND/AIMS: To determine the efficacy of portal vein embolization (PVE) against unresectable hepatocellular carcinoma (HCC). METHODOLOGY: We conducted a comparative study using 17 patients with HCC determined to be unresectable and who received a combination of PVE and transarterial chemoembolization (TACE) (PVE group) and 22 HCC patients with tumors in the unilateral lobe, which were treated only with repeated TACE (TACE group) from January 2000 to December 2008. RESULTS: There were no significant differences in background factors except for gender between the two groups. The cumulative intrahepatic recurrence rates in the non-portal-embolized area (in the contralateral lobe for the TACE group) at 1 year and 3 years was 41.1% and 58.8% in the PVE group and 77.3% and 81.8% in the TACE group, respectively. The former was significantly lower (p<0.05). The cumulative overall survival rate at 1 year, 3 and 5 years was 88.2%, 38.2% and 38.2% in the PVE group, and 68.1%, 22.7% and 8.5% in the TACE group, respectively. The former was significantly higher (p<0.05). CONCLUSIONS: Although in patients with unresectable HCC, when HCC is localized in the portal-embolized area, PVE combined with TACE can prevent intrahepatic metastasis to the non-portal-embolized area and improve overall survival.

RESUMEN

BACKGROUND/AIMS: To clarify the clinical benefits of the maneuver in right-side hepatectomy. METHODOLOGY: Eighty-one patients with liver tumor (54 hepatocellular carcinoma, 17 metastatic liver tumor and 10 other tumors) treated with a right-side hepatectomy were prospectively analyzed. The patients were divided into the following three groups: a conventional approach (group A, n=21); liver dissection under the hanging maneuver after liver mobilization (group B, n=19) and liver dissection under the hanging maneuver prior to liver mobilization (group C, n=41). RESULTS: The liver hanging maneuver was safely performed in all the patients in groups B and C. Tumor size had a significantly positive correlation with the amount of intraoperative blood loss (R=0.52, p<0.05) in group A only. The patients in groups B and C had a significantly lower intraoperative use of blood loss (both p<0.01), operation time (p<0.05 and p<0.01) and the frequency of blood product (both p<0.05), in comparison to group A, respectively. The postoperative morbidity and the mortality rates were similar in the three groups. CONCLUSIONS: Liver hanging maneuver is a safe procedure, which can decrease intraoperative blood loss and administration of blood product in right-side hepatectomy.

RESUMEN

Background: A variety of factors for short- and long-term outcomes have been reported after radical resection for gastric cancer (GC). Obesity and emaciation had been reported to be a cause of poor short- and long-term outcomes with gastrointestinal cancer. However, the indicators are still controversial. The purpose of this study was to evaluate the relationship between perirenal thickness (PT) and short- and long-term outcomes after radical surgery for GC. Methods: We analyzed the data of 364 patients with GC who underwent radical surgery. We evaluated the distance from the anterior margin of the quadratus lumborum muscle to the dorsal margin of the left renal pole using computed tomography (CT) as an indicator of PT. The association between PT and clinicopathological factors and short- and long-term outcomes was evaluated. Results: The PT data were divided into low, normal, and high groups by gender using the tertile value. We found that the PT low group was 121 patients, normal group was 121 patients, and high group was 122 patients. Multivariate analyses showed that the high PT group was an independent risk factor for a short-outcome after curative surgery in GC patients (odds ratio 2.163; 95% confidence interval [CI] 1.156-4.046; P = .016). And the low PT group was an independent risk factor for overall survival (hazard ratio 2.488; 95% CI 1.400-4.421; P = .0019) and relapse-free survival (hazard ratio 2.342; 95% CI 1.349-4.064; P = .0025) after curative surgery in GC patients. Conclusion: Perirenal thickness is a simple and useful factor for predicting short- and long-term outcomes after radical surgery for GC.

RESUMEN

We describe how we resected a hepatic angiomyolipoma and ascending colon cancer synchronously via laparoscopic left lateral segmentectomy and laparoscopic right colectomy, respectively. The patient was a 72-year-old man, admitted to our hospital after a liver tumor and ascending colon cancer were detected during a general health check. Computed tomography (CT) showed a hypervascular liver tumor mimicking hepatocellular carcinoma, 2 cm in diameter, in segment 3 of the liver. The ascending colon cancer was diagnosed as T2N0M0, Stage I. The left lateral liver and right colon were mobilized laparoscopically and hepatic transaction, followed by resection and anastomosis of the colon, were performed extracorporeally through the same 7-cm upper median incision. This type of laparoscopy-assisted combined resection is useful to obtain a pathological diagnosis of the liver tumor and to remove the entire tumor in a minimally invasive and cosmetic manner.

RESUMEN

The role of sorafenib is unclear in multimodal treatment for hepatocellular carcinoma (HCC). We analyzed patients who underwent multimodal treatment including surgical operation for advanced HCC after administration of sorafenib. A 79- year-old man underwent extended right hepatectomy for Stage III huge HCC. Three years later, multiple recurrences observed in the liver, and an extrahepatic tumor was diagnosed. Peritoneal seeding was suspected, thus we decided to start a sorafenib administration. After 11 months, new intrahepatic lesions were detected, but extrahepatic tumor was unchanged. We considered the extrahepatic tumor was solitary and resectable, and new lesions in the liver were still treatable, then we attempted a surgical treatment with partial hepatectomy and ablation therapy. The tumor was successfully resected, and residual viable tumors were treated by radiofrequency ablation. The patient remains alive without recurrence at 7 months. We could perform a surgical treatment for another 2 patients with sorafenib treatment. These results suggested that there are cases of advance HCC in which multimodality treatment including surgical treatment can be achieved after sorafenib administration.

RESUMEN

BACKGROUND: Solitary fibrous tumor (SFT) is a relatively rare mesenchymal tumor that mainly affects adults. Its prognosis is good after curative resection, but distant recurrences after 10 years or longer have been reported. Recurrent SFT usually arises as a local lesion; distant metastasis is rarely reported. Here, we report lung metastases that recurred a decade after excising a retroperitoneal primary SFT. CASE PRESENTATION: A 44-year-old woman had an SFT resected from her right retroperitoneum at our hospital. Ten years later, at age 54, she underwent a lung resection after CT showed three suspected metastases in her left lung. All three were histologically diagnosed as lung metastases from the retroperitoneal SFT. However, whereas the primary SFT had 1-2 mitotic cells/10 high power fields (HPF), the metastatic lesion increased malignancy, at 50/10 HPF. CONCLUSION: Patients who have had resected SFTs should be carefully followed up, as malignancy may change in distant metastasis, as in this case.

RESUMEN

AIM: The aim of the current study was to investigate whether the artery-first approach (AFA) improved surgical outcomes of pancreaticoduodenectomy (PD) at our non-high-volume center. PATIENTS AND METHODS: We retrospectively reviewed data on 121 consecutive patients who underwent PD between January 2009 and December 2018. The perioperative data of 49 patients who underwent conventional PD (conventional group) and 72 patients who underwent PD via artery-first approach were analyzed and compared to assess the effectiveness of the AFA. RESULTS: Although no significant difference was observed between the two groups overall, in those with pancreatic cancer, the duration of surgery, intraoperative blood loss and transfusion rate in the AFA group (n=33) were significantly lower than those for the conventional group (n=11) (p=0.011, p=0.021 and p=0.038 respectively). CONCLUSION: AFA can be used to reduce the operative time, intraoperative blood loss, and transfusion rate in patients with pancreatic cancer.

RESUMEN

BACKGROUND: Solid pseudopapillary neoplasm of the pancreas is a rare tumor in young women, metastasizing in only 5-15% of cases, and most commonly to the liver. Although treatment guidelines have not been established, surgical resection is usually performed. We report a rare case of repeat hepatectomy for liver metastases after distal pancreatectomy with solid pseudopapillary neoplasm. CASE PRESENTATION: The patient was a 71-year-old woman who underwent distal pancreatectomy for solid pseudopapillary neoplasm, and liver metastasis occurred 4 years after the first surgery. Partial liver resection was performed for four liver metastases, and histopathological examination revealed a diagnosis of liver metastasis from solid pseudopapillary neoplasm. However, 18 months later, liver metastases were detected again; three tumors were identified, and partial resection was performed, which has provided 18 months' recurrence-free survival. CONCLUSIONS: Long-term prognosis can be expected following R0 resection for resectable liver metastasis from solid pseudopapillary neoplasm.

RESUMEN

BACKGROUND AND OBJECTIVES: It is important to identify prognostic factors in patients with hepatocellular carcinoma (HCC) before hepatectomy. No previous studies have addressed the predictive efficacy of the preoperative doubling times of alpha-fetoprotein (AFP) and protein induced by vitamin K absence (PIVKA-II). METHODS: A total of 210 HCC patients who underwent a hepatic resection between 1998 and 2006 were prospectively evaluated. Serum AFP and PIVKA-II levels were measured at least twice before surgery to calculate the doubling times. Nineteen clinical factors that can be examined preoperatively, including the doubling times of AFP and PIVKA-II were investigated to identify prognostic factors for disease-free and overall survival after hepatectomy. RESULTS: There was no relationship between preoperative levels and doubling times of AFP and PIVKA-II. In a multivariate analysis, patients with a doubling time of AFP ≤30 days and PIVKA-II ≤16 days showed a significantly worse disease-free (P = 0.02, P = 0.03, respectively) and overall survival (P < 0.0001, P = 0.03, respectively). CONCLUSIONS: In HCC patients, the doubling times of preoperative serum AFP or PIVKA-II levels are useful tools to predict early postoperative recurrence and a poor prognosis.

RESUMEN

BACKGROUND: This study was performed to clarify the influence of preoperative chemotherapy on liver function and the correlation between histological hepatic injury and the postoperative outcome in patients with colorectal liver metastases who underwent a hepatic resection. METHODS: Twenty-seven patients who underwent a hepatic resection for colorectal liver metastases were included. Fifteen patients with initially unresectable colorectal liver metastases who were able to undergo a tumor resection after FOLFOX (oxaliplatin plus fluorouracil and leucovorin, with a mean number of 7.7 cycles) were compared to 12 patients who underwent a hepatectomy with no preoperative chemotherapy. The postoperative mortality, morbidity, changes in liver function tests, and pathology of the resected liver were examined. RESULTS: Preoperative FOLFOX therapy was significantly associated with the macroscopic appearance of oxaliplatin-associated blue liver (p = 0.02), and a tendency toward sinusoidal dilatation (33.3% in the FOLFOX group versus 8.3% in the no-chemotherapy group, p = 0.056). Preoperative liver function tests showed that the albumin and indocyanine green retention rate at 15 min (ICG-R15) test values were significantly worse after FOLFOX therapy; however, intraoperative events, postoperative liver function test values, and morbidity rates were similar in the two groups. There was no postoperative mortality in any of the patients. CONCLUSIONS: Although preoperative FOLFOX administration in patients with colorectal liver metastases caused macroscopic blue liver, microscopic sinusoidal dilatation in the liver parenchyma, and a significant decrease in liver function, there was no increase in the morbidity and mortality rates, in comparison to findings in patients without preoperative chemotherapy.

RESUMEN

A 75-year-old woman was admitted to our department because of epigastric pain. Imagings revealed cancer of the head of the pancreas. She was an HBV carrier, although no liver dysfunction was observed. Her serum HBV-DNA level was lower than 2.6. We performed pancreaticoduodenectomy for pancreatic cancer. No postoperative complication was observed. The histopathological diagnosis was tubular adenocarcinoma of the pancreas. As a postoperative adjuvant chemotherapy, gemcitabine hydrochloride (GEM) was injected at a dose of 800mg/m2 once a week. Disorientation and jaundice were observed after six doses of GEM. Blood chemistry revealed that total bilirubin and ammonia were abnormally elevated, and that blood coagulant factors were diminished. Serum HBV-DNA level was lower than 2.6. It showed no reactivation of HBV. Abdominal CT showed no recurrence but fatty liver. Fresh frozen plasma was supplied and branched chain amino acids were injected after GEM was administration discontinued. Lactulose was also given orally. With these conservative treatments, she recovered completely. Careful monitoring of liver function during GEM administration is required in a HBV carrier.

RESUMEN

BACKGROUND: Although cumulative evidence supports the fact that stromal myofibroblasts promote tumor progression, the influence of myofibroblasts on intrahepatic cholangiocarcinoma (ICC) is unclear. We hypothesized that hepatic stellate (HS) cells can differentiate into myofibroblasts in ICC stroma and that they promote cancer progression. This study aims to: (1) assess the influence of myofibroblasts on the prognosis of ICC, (2) identify HS cells in ICC stroma, and (3) investigate the interaction between HS cells (LI90 and LX-2) and ICC cells (HuCCT-1 and MEC) in vitro. METHODS: The association between alpha-smooth muscle actin (alpha-SMA) expression and the prognoses of 46 ICC patients after hepatic resection was evaluated by immunohistochemical analysis. The HS cells in myofibroblasts of ICC were identified (double immunostaining) using antibodies for alpha-SMA, glial fibrillary acidic protein (GFAP), and desmin. The influence of HS cells on the invasion and growth of ICC cells was examined in vitro using a coculture system. RESULTS: Patients with high alpha-SMA expression exhibited the worse outcomes. Multivariate analyses revealed that high alpha-SMA expression (P = 0.0045) and positivity for lymph-node metastasis were independent prognostic factors. Because desmin- or GFAP-positive cells coexpressing alpha-SMA were observed in the ICC samples, they were considered to be derived from the HS cells. On coculturing with HS cells, a remarkable increase was observed in the invasion and growth of the two ICC cell lines. CONCLUSIONS: Stromal myofibroblasts may relate to the poor prognoses in ICC patients. HS cells appear to be involved in the progression of ICC.

RESUMEN

BACKGROUND: Poorly differentiated hepatocellular carcinoma (HCC) has a malignant potential such as frequent microvascular invasion even if the tumor is smaller than 3 cm in diameter. The aim of this study was to clarify the preoperative predictors of poorly differentiated HCC for safe local ablation therapy. METHODS: Sixty-six patients underwent a hepatic resection for solitary small-sized HCC (

RESUMEN

Hepatoblastoma is a rare malignancy in adults. It is often diagnosed after the appearance of symptoms, therefore, the tumor size tends to be larger. In patients with no indication for a hepatic resection, the prognosis of adult hepatoblastoma is quite poor. A 54-year-old man with hepatitis C virus-associated liver cirrhosis was initially treated with a hepatic resection for a hepatic tumor, 3 cm in diameter. The tumor consisted of osteoid-like and cartilaginous foci, myxomatous stroma, and poorly differentiated hepatocellular carcinomatous cells and was diagnosed as a mixed epithelial and mesenchymal hepatoblastoma. Two years after the first operation, multicentric hepatocellular carcinomas developed in the remnant liver and were successfully treated with a secondary hepatic resection combined with radio-frequency ablation. The patient is now alive with no recurrence at 5 years after the initial hepatectomy. To the best of our knowledge, the primary hepatoblastoma was the smallest such tumor reported and this is the first report of a metachronous hepatoblastoma and hepatocellular carcinoma in an adult hepatitis patient.
