RESUMO
A case oflaparoscopic lymphadenectomy in a patient with lymph node recurrence after endoscopic submucosal dissection (ESD)is presented. A 77-year-old man underwent ESD for gastric cancer. After 2 years, the patient was referred to our hospital with the diagnosis of lymph node recurrence. We offered radical surgery, including gastrectomy and lymphadenectomy; however, this suggestion was denied by the patient because ofstrong anxiety for gastrectomy. As an alternative therapy, laparoscopic lymphadenectomy for the limited area of high recurrence, without gastrectomy, was performed. Postoperative course was uneventful. The patient was discharged on the 10th postoperative day and remains cancer-free over 2 years after the operation. Laparoscopic lymphadenectomy for high risk area of recurrence may be considered in frail elderly patients to avoid the high burden ofgastrectomy.

A 52-year-old patient presented with epigastric pain.An enhanced CT scan showed a strongly enhanced appendix with abscess formation.Appendectomy was performed under the diagnosis of acute appendicitis with perityphlitic abscess.The stump of the appendix was white and hard, suggesting malignant transformation.Intraoperative frozen sectional examination indicated goblet cell carcinoid(GCC)of the appendix.Thereafter, we performed ileocecal resection with lymphadenectomy (D3).The final pathological diagnosis was GCC, pSS, pN1, Stage III a by the Japanese classification of colorectal carcinoma. Immunohistochemical examination was consistent with GCC including synaptophysin(+), chromogranin A(+), somatostatin receptor(SSTR)2(±), SSTR5(+), and cytokeratin 20(+).The patient received adjuvant chemotherapy and remains cancer-free over 5 years after the operation.

An 82-year-old woman underwent upper gastrointestinal endoscopy to evaluate upper abdominal pain.A type 2 tumor (adenocarcinoma, por, HER2+)was found in the lesser curvature of the gastric antrum.Abdominal CT showed bulky lymph node metastases and pancreatic invasion of lymph node No.6 , resulting in a diagnosis of cT3N3M0, Stage III B.Radical resection was not possible by gastrectomy, and chemotherapy(capecitabine plus cisplatin plus trastuzumab)was administered. The primary lesion and lymph node showed significant regression on CT after the administration of 8 courses of chemotherapy, which also clarified the border between the lymph node and pancreas.At this stage, it was determined that radical resection was feasible; distal gastrectomy(Roux-en-Y reconstruction)and D2 dissection and cholecystectomy were performed.No cancer cells were found in the primary lesion on histopathology.The therapeutic effect of preoperative chemotherapy was assessed as Grade 3, pCR, and retained tumor was only found in lymph node No.5 . On follow-up observation, the patient is alive 11 months after surgery, with no evidence of recurrence without neoadjuvant chemotherapy.

A 70-year-old man with a history of myocardial infarction (MI) and taking 2 antiplatelet drugs was diagnosed with anemia his 6-month post-MI checkup. A lower gastrointestinal endoscopy detected ascending colon cancer, and contrast-enhanced a computed tomography scan revealed hilar cholangiocarcinoma as well as lesions suspicious for gastrointestinal stromal tumors of the small intestine. The patient was given a preoperative diagnosis of synchronous triple malignant tumors. The decision to perform a two-stage procedure was made for the following reasons: the impossibility of discontinuing antiplatelet drugs 6 months after drug-eluting stent placement, continuous bleeding due to colon cancer and the possibility of suffering severe stress from surgery while at high risk for diseases such as hepatic failure. In the initial procedure, a right hemicolectomy and surgical resection of the mesenteric tumor (later diagnosed as a liposarcoma) were performed after portal vein embolization. Confirmation of an enlarged residual liver was confirmed 2 months after the initial procedure. The patient underwent right hepatectomy and resection of the extrahepatic bile duct and the biliary tract was surgically reconstructed. Safe resection of tumors was successfully performed by choosing a two-stage procedure for triple malignancy, including hilar cholangiocarcinoma, ascending colon cancer, and liposarcoma, in a single patient.

A 32-year-old man was admitted to our hospital with the complaint of epigastric pain. Gastrointestinal endoscopy revealed a type 5 advanced gastric cancer at the posterior wall of the antrum. Contrast-enhanced computed tomography (CT) and endoscopic ultrasonography showed a fluid collection, indicating peritoneal metastasis. CEA levels were elevated, at 16.5 ng/mL. A diagnosis was made of cStage â £ (T4aN3H0P1M1), and he underwent first-line chemotherapy using CDDP and S-1. However, this immediately failed with the severe adverse effect of vomiting.Docetaxel and S-1 were adopted as second-line chemotherapy. Since progression of the disease was confirmed after 8 cycles of second-line chemotherapy, nab-paclitaxel was administered as third-line chemotherapy. Despite a trend of increasing CEA after 4 cycles of third-line chemotherapy, CT revealed a tumor volume reduction as well as the disappearance of the fluid collection, after which staging laparoscopy was performed. Based on the finding that non-curative factors such as fluid collection and peritoneal nodules were not observed, distal gastrectomy was performed. Histopathological examination showed a ypStage â A (T1bN0H0P0M0)tumor with a grade 3 therapeutic response to chemotherapy.The patient is currently doing well with no recurrence 11 months after the operation.

The case is of a 62-year-old man with no medical history and no family history.A type 2 tumor was found in the entire circumference of the sigmoid colon by colonoscopy after a positive result on a fecal occult blood test, and 5 liver metastases were recognized in both lobes of the liver by using contrast-enhanced CT.He was first treated by primary tumor resection. Subsequently, 5-fluorouracil/l-leucovorin/oxaliplatin (mFOLFOX6) plus bevacizumab (BV) was started 1 month after the surgery and a total of 8 cycles of mFOLFOX6 plus BV were administered without any adverse events.On CT assessment after the chemotherapy, the patient was diagnosed with stable disease according to RECIST guidelines since the size of the tumor only showed a slight reduction.However, it was considered to be an optimal response based on the morphologic criteria. Thereafter, a medial segmentectomy and partial resection of the liver was performed.A mucus reservoir was found in the tumor site, and no viable tumor cells were detected pathologically, which confirmed the pathological complete response with mFOLFOX6 plus BV.

BACKGROUND: The value of pancreatoduodenectomy (PD) with extended lymphadenectomy for pancreatic cancer has been evaluated by many retrospective studies and 3 randomized controlled trials (RCT). However, the protocols used and the results found in the 3 RCTs were diverse. Therefore, a multicenter RCT was proposed in 1998 to evaluate the primary end point of long-term survival and the secondary end points of morbidity, mortality and quality of life of patients undergoing standard versus extended lymphadenectomy in radical PD for pancreatic cancer. METHODS: From March 2000 to May 2003, 112 patients with potentially curable pancreatic head cancer were enrolled and intraoperatively randomized to a standard or extended lymphadenectomy group. No resected patients received any adjuvant treatments. RESULTS: A hundred and one eligible patients were analyzed. Demographic and histopathological characteristics of the two groups were similar. The mean operating time, intraoperative blood loss and number of retrieved lymph nodes were greater in the extended group, but the other operative results were comparable. CONCLUSIONS: Although this multicenter RCT was conducted in a strict setting, extended lymphadenectomy in radical PD did not benefit long-term survival in patients with resectable pancreatic head cancer and led to levels of morbidity, mortality and quality of life comparable to those found after standard lymphadenectomy.

Some hemophilic patients in Japan suffer from infections with both human immunodeficiency virus (HIV) and hepatitis virus because they received contaminated nonheated blood products. Coinfection with HIV appears to accelerate the course of chronic hepatitis. Although powerful antiviral therapy was introduced as HIV treatment and the prognosis of HIV patients was dramatically improved, the risk of rapid progression of hepatitis and carcinogenesis remains for the patients. Recently, we performed surgery for hepatocellular carcinoma (HCC) in two hemophilic patients with HIV and hepatitis C virus (HCV) coinfection. Case 1 was a 52-years-old man who suffered from liver cirrhosis, hypersplenism, and hyperammonemia due to portosystemic shunt. A recent abdominal computed tomography (CT) scan had revealed a low-density area in segment VI of the liver. Splenectomy and partial resection of the liver were performed. Case 2 was a 66-year-old man who had been diagnosed with chronic hepatitis at age 50, and HIV infection at age 52 years. When his serum alpha-fetoprotein level was increased, CT scan of the liver revealed a mass in segment VIII. Subsegmentectmy of the liver was performed. Although the CD4 value in each patient was lower than 200 micro l, the operations were safely carried out and no major complication occurred. Because the chance of encountering HCC patients infected with HIV and HCV is increasing in Japan, we should consider the perioperative care of these patients, as well as the protection of medical workers against HIV infection.

Surgical practice for gastric cancer in Japan is based on the Gastric Cancer Treatment Guidelines issued in 2001 by the Japanese Gastric Cancer Association. These recommendations list options for treatment of each stage of cancer, with clear distinctions between interventions recommended for routine use and those that should be confined to trial settings until further evidence for their curative potential becomes available. In this review, we discuss standard surgery, local resection, segmental resection, and pylorus-preserving gastrectomy (PPG) as examples of limited resection and describe in detail the indications for limited lymph-node dissection in cases of early-stage gastric cancer. At present, evidence does not support the conclusion that limited surgery is effective for local resection or for improving quality of life. Thus, use of limited surgery should be considered an experimental approach both in Japan and the West. We conclude that surgeons who are familiar with the criteria for selecting surgical procedures should decide on a case-by-case basis which technique is most appropriate. Choices should be made with consideration of the stage of the cancer, invasiveness of the surgical procedure, and the patient's history. For all procedures, the patient must give informed consent and the surgeons must accurately assess the success of the operation after surgery.

BACKGROUND/AIMS: Although the progression of hilar bile duct cancer is slow, without adequate treatment the prognosis becomes poor. Margin-positive or negative resection has often been reported to correlate with the prognosis. Moreover, the value of combined vessel resection for hilar bile duct cancer is still obscure. METHODOLOGY: Fifty-five out of 98 cases of hilar bile duct cancer were treated with surgery. The patients were classified as a microscopic margin-positive resection group with 12 cases and a microscopic margin-negative resection group with 43 cases. The agreement between preoperative diagnosis and pathological findings of resected specimens was examined, as were cumulative survival rates according to clinical and pathological factors. RESULTS: In diagnosis of portal invasion with computed tomography, the rate of coincidence, overestimate and underestimate were 69.8%, 13.2% and 17.0%, respectively. Corresponding rates in diagnosing arterial invasion were 58.5%, 15.1% and 26.4%, respectively, and for lymph node metastasis 54.7%, 9.4% and 35.8%, respectively. The 5-year survival rates for margin-positive and negative resection groups were 17.9% and 26.5%, respectively (NS). Patients surviving for more than 1 year in the margin-positive resection group tended to exhibit exposed cancer cells only at the bile duct, rarely showing lymph node metastases. Combined arterial resection had a poor prognosis and high, usually lethal, complication rates. CONCLUSIONS: Accurate preoperative diagnosis rates of vessel invasion and lymph node metastasis were 60-70% and 56%, respectively. The long-term survival was expected even in margin-positive resection cases without lymph node metastasis. Combined hepatic arterial resection showed no clinical advantage.

PURPOSE: Although many studies have focused on clinical risk factors for prognosis of patients with surgically treated gastric cancer, little information is available regarding the timing of recurrent malignant disease. The purpose of this study was to determine the factors that are predictive of early and late recurrences after gastrectomy. PATIENTS AND METHODS: We reviewed the hospital records of patients with hisotological proof of gastric cancer who were admitted to Sendai National Hospital during the period from 1985 to 1995. A total of 923 records were examined, and 251 patients with recurrent disease were identified. The patients were divided into an "early recurrence group" consisting of 195 patients (died within one year after surgery) and a "late recurrence group" of 56 patients (died two years or more after surgery). Clinicopathological characteristics were examined, and independent risk factors influencing the timing of recurrence were determined by a multiple logistic regression analysis. RESULTS: The mean tumor size of early recurrence cases was larger than that of late recurrence cases (p=0.0294). Tumors penetrating the serosa with direct invasion to continuous structures were found more frequently in the early recurrence group than in the late recurrence group. The patients with early recurrence showed a higher tendency to have nodal involvement, lymphatic invasion and vascular invasion. The relative risks of early and late recurrences associated with different variables were estimated by a multiple logistic regression method. The following variables were found to be significant risk factors for early recurrence: male gender (p=0.0382), lymph node metastasis (p=0.0016), and vascular invasion (p=0.0006). CONCLUSION: Male patients who have node-positive gastric cancer with vascular invasion have a high risk of early recurrence.

BACKGROUND: Retrospective studies using multivariate analysis of clinical and pathological features in gastric cancer have identified a number of high-risk, independent prognostic factors. In these clinical features, tumor size can be measured easily before or during the operation without the requirement of any special equipment, but its prognostic value in patients with gastric cancer is unclear. The aim of this study was to review the experience at our institution of gastric adenocarcinoma to determine the influence of tumor size on outcome. PATIENTS AND METHODS: Between January 1985 and December 1995, 697 patients with gastric adenocarcinoma underwent resection of the stomach at the Department of Surgery, Sendai National Hospital, Japan. Data on age, gender, tumor location, structure and size, evidence of local invasion, and type of operation performed for each patient were obtained. The sizes of tumors were derived from measurements made in fresh resected specimens. The patients were divided into three groups: 102 patients with tumors of less than 2 cm in diameter, 392 patients with tumors of 2-7 cm in diameter, and 203 patients with tumors of more than 7 cm in diameter. RESULTS: In these three groups, there were statistical differences in tumor location, macroscopic type, depth of invasion, lymph node metastasis, histological type, lymphatic invasion, vascular invasion and cancer-stromal relationship. Patients with larger tumors had more invasion into the gastric wall in terms of depth of invasion and more frequent lymph node metastasis than did patients with smaller tumors. Histologically, diffuse, scirrhous-type was more common in the larger tumor group. The frequency of lymphatic and vascular permeation in the larger tumor group was higher than that in the other groups. The 5-year survival rates according to tumor size were 94.3% in cases of tumors of less than 2 cm, 75.1% in cases of tumors of 2-7 cm, and 26.3% in cases of tumors of more than 7 cm. Multivariate analysis revealed that the prognosis of gastric cancer patients was affected most by depth of invasion, followed by lymph node metastasis and tumor location. Tumor size is not an independent prognostic factor. CONCLUSION: In conclusion, according to the results of univariate analysis, tumor size is clinically a predictor of survival of patients with gastric cancer. In multivariate analysis, however, it is not an independent factor, and the presence of lymph node metastasis, depth of invasion and tumor location are more important than tumor size.
