Abstract Background Postoperative adjuvant chemotherapy using oxaliplatin in addition to 5-FU-based anticancer agents has become the standard treatment for colorectal cancer, however, there is insufficient evidence regarding efficacy and safety of combination therapy elderly patients. In this study, retrospective analysis results from CCOG-1302 study was performed confirm them. Methods The patients CAPOX continuous (8 courses CAPOX) intermittent (2 + 4 capecitabine 2 arms were divided into...

The pretreatment albumin-globulin ratio (AGR) is a frequently used inflammation-associated factor that has been reported to have associations with the survival outcomes of various malignancies.We retrospectively analyzed 162 patients pancreatic cancer who underwent preoperative treatment followed by curative surgery at Nagoya University Hospital between April 2010 and December 2020. Representative nutritional status indicators neutrophil-lymphocyte (NLR), platelet-lymphocyte (PLR),...

This report describes a very rare case of synovial chondromatosis with deposition calcium pyrophosphate dihydrate (CPPD) crystals (pseudogout) in the temporomandibular joint (TMJ) 46-year-old male patient. Synovial is non-neoplastic disease characterized by metaplasia connective tissue leading to chondrogenesis membrane. Pseudogout an inflammatory joints caused CPPD, producing similar symptoms those observed gout but not hyperuricaemia. Both diseases commonly affect knee, hip and elbow...

Abstract Background Large type 3 (diameter ≥ 8 cm) and 4 gastric cancers have been arbitrarily combined in Japan as a single entity. However, whether these two types are oncologically similar remain unclear. This study aimed to clarify this issue. Methods In retrospective study, we analyzed database of 3,575 patients from nine institutions who underwent gastrectomy between 2010 2014. Using propensity scores balance significant variables, compared prognoses tumor recurrences. Results Of with...

Intra-abdominal desmoid tumors are usually slow growing and solitary, but multifocal develop on rare occasions. Diagnosing before histological examination of a surgical biopsy is often difficult. In particular, if patient has prior history malignancy, it may be difficult to differentiate between these lesions disease recurrence or metastasis.We present case multiple rapidly intra-abdominal after trauma, without familial adenomatous polyposis. A 51-year-old male underwent abdominal perineal...

Background/Aim: Pancreatic cancer cells release certain tissue factors into the bloodstream. It is well known that pancreatic progresses with thrombus formation. Because we routinely measure serum D-dimer levels in preoperative patients as a screening marker of deep venous thrombosis, examined its association high our cohort resected cases. Patients and Methods: We 315 ductal adenocarcinoma who underwent surgical resection department from January 2012 to July 2021. All cases were divided...

Adequate surgical margins following gastrectomy for gastric cancer are required. In addition, a method accurately detecting tumor location without palpation is needed during robotic surgery. Although several methods have been reported, most of these either lack accuracy or require increased time and effort intraoperative detection. Herein, we introduce new using preoperative indocyanine green (ICG) marking the built-in ICG detection system da Vinci Xi Surgical System in to determine...

Pancreatic fistula after gastrectomy with lymph node dissection is associated prolonged hospital stay and critical complications such as intra-abdominal bleeding sepsis. Polyglycolic acid (PGA) sheets are absorbable suture reinforcement materials. A randomized Phase II trial has been planned to evaluate the effect of PGA on preventing postoperative pancreatic fistula. total 320 patients will be recruited from thirteen institutions. Patients who scheduled undergo distal or randomly allocated...

This retrospective study examined early the predictive factors for successful conversion surgery (CS) with R0 resection in patients metastatic gastric cancer (MGC) who underwent systemic chemotherapy. included 204 diagnosed adenocarcinoma, received chemotherapy between 2009 and 2019. Of these patients, 31 (15%) CS resection. The incidence of was not affected by volume lesions or presence peritoneal metastasis. overall survival time group significantly longer than that non-CS (hazard ratio,...
