Background/aim: We aimed to assess the risk factors for postoperative complications and long-term outcome of patients aged ≥80 years after curative resection for gastric cancer (GC).
Patients And Methods: Patients aged ≥80 years who underwent curative gastrectomy for stage I-III GC between 2013 and 2020 were included. Clinical factors were retrospectively analyzed.
Schwannomas that occur in the retroperitoneal cavity are rare. We herein report a patient who underwent safe laparoscopic resection by using a preoperative 3D computed tomography (CT) image and a fluorescent ureteral stent during the surgery. A 47-year-old man presented with left lower abdominal pain.

Advanced age is a risk factor for adverse outcomes after surgery. This study aimed to evaluate the short- and long-term outcomes of curative resection for colorectal cancer in nonagenarians.
View Article and Find Full Text PDFObjective: Resection is usually recommended for locally recurrent rectal cancer (LRRC) for which R0 resection is possible, but its suitability varies by individual patient risk. Here, we report outcomes of resected LRRC in our hospital.
Methods: We retrospectively evaluated short- and long-term results of 33 patients who underwent resections for LRRC from January 2003 to December 2019.
Background/aim: Perforation and postoperative complications have a negative effect on long-term outcomes in patients with colorectal cancer (CRC). The aim of this study was to evaluate the clinical factors with special reference to postoperative complications predicting the long-term outcome in those for whom curative resection for perforated CRC was performed.
Patients And Methods: Patients who underwent curative resection for perforated CRC at stage II or III from April 2003 to March 2020 were included.
Introduction: Lung cancer is one of the most common cancers. On the other hand, lung cancer metastasis to the appendix is extremely rare, and in many cases it has been diagnosed with the onset of acute perforating appendicitis.
Presentation Of Case: An 85-year-old man with fever and abdominal pain visited our hospital.
Background: Hemostasis is very important for a safe surgery, particularly in endoscopic surgery. Accordingly, in the last decade, vessel-sealing systems became popular as hemostatic devices. However, their use is limited due to thermal damage to organs, such as intestines and nerves.

Although ACC is classified as a low-grade tumor, metastases are frequently identified in the late period. Extrapulmonary metastases are rare, and their resection has rarely been reported.
View Article and Find Full Text PDFBackground/aim: Identifying useful biomarkers is central to selecting optimal therapeutic strategies for esophageal squamous cell carcinoma (ESCC). Serum p53 antibody (S-p53Ab), squamous cell carcinoma antigen (SCC-Ag), and carcinoembryonic antigen (CEA) were investigated to evaluate the significance of single and combined tumor markers in determining the diagnosis and prognosis of ESCC.
Materials And Methods: Serum samples were obtained preoperatively from 133 patients with histologically-confirmed ESCC, including 32 patients with stage I (24.
The aim of the present study was to investigate the prognostic value of the C-reactive protein-to-albumin ratio (CAR) and compare it with other inflammation-based prognostic scores (Glasgow prognostic score, modified Glasgow prognostic score, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, prognostic nutritional index and prognostic index) in patients with esophageal squamous cell cancer (ESCC). A database of 116 patients with primary ESCC who underwent treatment at the Division of Surgical Oncology at Nagasaki University Hospital between January 2007 and August 2014 was retrospectively reviewed and the correlations between CAR and overall survival (OS) were investigated. Kaplan-Meier and Cox regression analyses were used to assess independent prognostic factors.

Serum tumor markers in patients with cancer assist with establishing diagnosis, estimating prognosis, monitoring treatment, and detecting tumor recurrence. Changes in the p53 tumor suppressor gene are the most common genetic abnormalities in many different human malignancies. Several studies have demonstrated that serum p53 antibodies (S-p53Ab) comprise an early marker of malignant disease, a marker for treatment effects and a prognostic factor for patients with several types of tumors.
View Article and Find Full Text PDFIntroduction: Multiple primary neoplasms are relatively rare, but their incidence has increased because of aging and improvements in diagnostic imaging.
Presentation Of Case: A 67-year-old man presented with epigastric pain. On upper gastrointestinal endoscopy, an ulcer was seen at the gastric angle, and biopsy showed moderately differentiated adenocarcinoma (AC).
Background: The aim of this retrospective study was to evaluate the clinical relevance of serum p53 antibody (S-p53Ab) as a biomarker and to investigate whether its diagnostic value could be improved when combined with other biomarkers of gastric cancer (GC).
Patients And Methods: Serum samples were obtained preoperatively from 208 patients with histologically-confirmed GC, including 126 stage I patients (60.6%).

Introduction: Single-incision laparoscopic surgery has been reported to be a safe and feasible technique for colorectal cancer. However, the technique needs skill due to the limitations of the device. An organ retractor is a new grasp device that has the potential to overcome these limitations.

Presentation Of Case: A 79-year-old man with melena visited our hospital.
Background/aim: Photodynamic therapy (PDT) is an effective laser treatment for locally treating advanced bile duct carcinoma (BDC). The study's objective was to evaluate the increased cytocidal effect by apoptotic PDT using a novel photosensitizer, glucose-conjugated chlorin, by irradiation of light-emitting diode laser (G-PDT) in comparison with conventional PDT using talaporfin sodium (T-PDT).
Materials And Methods: The cytocidal effect of G-PDT was compared to that of T-PDT as a control.
Background/aim: Oxidative stress is defined as an imbalance between the pro-oxidant and antioxidant potential of cells leading to intracellular DNA damage. To clarify the oxidative stress response as a tumor marker, we investigated measurement of urinary 8-hydroxydeoxyguanosine (8-OHdG) levels in hepatobiliary diseases.
Materials And Methods: Relationships between urinary 8-OHdG levels and clinicopathological factors were analyzed in 101 patients, including 84 with hepatobiliary malignancies, and 18 healthy volunteers.
Objectives: To determine the use of the mucin proteins MUC5B and MUC5AC as prognosis markers for non-small cell lung cancer (NSCLC) carrying epidermal growth factor receptor (EGFR) mutations.
Setting: Patients who underwent surgical resection at Nagasaki University Hospital and related facilities in Japan between June 1996 and March 2013.
Participant: 159 Japanese patients (male: n=103; female: n=56) with NSCLC, who underwent surgical resection (EGFR-mutant type: n=78, EGFR wild type: n=81).
Aim: To evaluate hepatic fibrosis and tumor diagnosis preoperatively, we investigated the elasticity calculated by the new parameter of ultrasonography, acoustic radiation force impulse (ARFI).
Methods: We examined ARFI of the non-tumorous right and left lateral liver and in the tumor by push pulse of probe in 95 patients with hepatic malignancies undergoing hepatectomy. Measurement of ARFI as hepatic stiffness was indicated as the Vs (m/s).
Background/aims: Despite recent advances in surgical techniques, blood loss is an important factor associated with postoperative outcomes in pancreatectomy. It is useful to identify risk factors of increased blood loss.
Methodology: The clinical records of 161 patients who underwent an elective pancreatectomy for peripancreatic diseases between 1994 and March 2011 were retrospectively examined.
Purpose: Despite recent advances in surgical techniques, blood loss can still determine the postoperative outcome of hepatectomy. Thus, the preoperative identification of risk factors predicting increased blood loss is important.
Methods: We studied retrospectively the clinical records of 482 patients who underwent elective hepatectomy for liver disease, and analyzed the clinicopathological and surgical parameters influencing intraoperative blood loss.
Aim: To clarify perioperative factors associated with poor survival following hepatectomy.
Patients And Methods: Clinical parameters and stress score, including surgical stress score (SSS) and comprehensive risk score (CRS) were examined from 183 hepatocellular carcinoma patients who underwent hepatectomy.
Results: Factors associated with tumor relapse were increased blood loss/weight, uncontrolled ascites and grade B liver damage (p<0.
