Open AccessThe clinical impacts of postoperative complications after colon cancer surgery for the clinical course of adjuvant treatment and survival
We investigated whether or not postoperative complications (POCs) themselves have a negative survival impact or indirectly worsen the survival due to insufficient adjuvant chemotherapy in a pooled analysis of ...

Open AccessClinical practice guidelines for duodenal cancer 2021
Duodenal cancer is considered to be a small intestinal carcinoma in terms of clinicopathology. In Japan, there are no established treatment guidelines based on sufficient scientific evidence; therefore, in dai...

Metabolic bone disorders after gastrectomy: inevitable or preventable?
Some authors have suggested that a relationship exists between gastrectomy for gastric cancer and metabolic bone disorders. However, few studies have investigated metabolic bone disorders after gastrectomy for...

Surgical results of non-ampullary duodenal cancer: a nationwide survey in Japan
As non-ampullary duodenal cancer is relatively rare, the optimal treatment strategy, including the appropriate surgical procedure and efficacy of adjuvant chemotherapy, remains unclear. This nationwide survey ...

Limited resection vs. pancreaticoduodenectomy for primary duodenal adenocarcinoma: a systematic review and meta-analysis
It is well known that surgery is the mainstay treatment for duodenal adenocarcinoma. However, the optimal extent of surgery is still under debate. We aimed to systematically review and perform a meta-analysis...

Open AccessDoes the Endoscopic Surgical Skill Qualification System improve patients’ outcome following laparoscopic surgery for colon cancer? A multicentre, retrospective analysis with propensity score matching
This study aimed to investigate the short-term and oncological impact of the Endoscopic Surgical Skill Qualification System (ESSQS) by the Japan Society for Endoscopic Surgery on the operator performing laparo...

Postoperative D-dimer elevation affects tumor recurrence and the long-term survival in gastric cancer patients who undergo gastrectomy
We retrospectively evaluated the blood coagulation activity using the D-dimer level in the early period after gastrectomy and investigated whether postoperative hypercoagulation affects tumor recurrence and lo...

Perioperative body composition changes in the multimodal treatment of gastrointestinal cancer
Surgical resection and perioperative adjuvant therapy are widely accepted standard treatments for gastrointestinal cancer. However, body composition changes, such as weight loss and skeletal muscle loss, are u...

Laparoscopic surgery in patients diagnosed with clinical N2 colon cancer
The benefits of laparoscopic surgery for colorectal cancer have been well established. Several randomized controlled trials have demonstrated similar oncological outcomes between laparoscopic and open surgery ...

Equivalent feasibility and safety of perioperative care by ERAS in open and laparoscopy-assisted distal gastrectomy for gastric cancer: a single-institution ancillary study using the patient cohort enrolled in the JCOG0912 phase III trial
Laparoscopy-assisted distal gastrectomy (LADG) has an advantage of earlier recovery after surgery due to having lower invasiveness and wound pain than open distal gastrectomy (ODG). However, whether the same e...

Changes in bone metabolism after gastric cancer surgery in male patients: a prospective observational study
Several retrospective studies have shown that bone disorders occur after gastric cancer surgery. This study was designed to prospectively evaluate the changes in bone metabolism after gastrectomy for gastric c...

A phase II trial of capecitabine plus cisplatin (XP) for patients with advanced gastric cancer with early relapse after S-1 adjuvant therapy: XParTS-I trial
In Japan, standard regimens for advanced gastric cancer (AGC) include S-1 chemotherapy. The standard treatment for early relapse after adjuvant chemotherapy with fluoropyrimidine alone is platinum-based chemot...

Priority of lymph node dissection for proximal gastric cancer invading the greater curvature
The therapeutic efficacy of dissection of the splenic hilar lymph nodes (#10) has not been fully evaluated in locally advanced proximal gastric cancer (LAGC) invading the greater curvature of the stomach.

Does a laparoscopic approach attenuate the body weight loss and lean body mass loss observed in open distal gastrectomy for gastric cancer? a single-institution exploratory analysis of the JCOG 0912 phase III trial
Laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer may prevent the loss of body weight and lean body mass resulting from reduced surgical stress in comparison to open distal gastrectomy (ODG). A...

Article
Adjuvant therapy for locally advanced gastric cancer
D2 gastrectomy is now the globally accepted surgical standard for locally advanced gastric cancer. However, since 2000, different evidence has emerged regarding the efficacy of adjuvant chemoradiation, periope...

The survival and prognosticators of peritoneal cytology-positive gastric cancer patients who received upfront gastrectomy and subsequent S-1 chemotherapy
Upfront surgery and subsequent S-1 chemotherapy is frequently selected for peritoneal cytology-positive (CY1) gastric cancer patients without other distant metastases (CY1-only). The objective of this study wa...

Article
Postoperative weight loss leads to poor survival through poor S-1 efficacy in patients with stage II/III gastric cancer
We previously demonstrated that body weight loss (BWL) at one month after gastrectomy, a common finding after surgery for gastric cancer, was an independent risk factor for the continuation of adjuvant chemoth...

Impact of preoperative hand grip strength on morbidity following gastric cancer surgery
Sarcopenia is a decrease in both muscle mass and strength. It remains unclear whether sarcopenia is associated with morbidity after gastric cancer surgery. This study evaluated the impact of sarcopenia on the ...

Quality of life and nutritional consequences after aboral pouch reconstruction following total gastrectomy for gastric cancer: randomized controlled trial CCG1101
Total gastrectomy has detrimental effects on postoperative nutritional status and quality of life (QOL), but it is often unavoidable in the treatment of gastric cancer. Roux-en-Y (RY) is the most common recon...

Body composition analysis within 1 month after gastrectomy for gastric cancer
A significant body weight loss (BWL) is observed during 1 month after gastrectomy for gastric cancer. However, it remains unclear which body component mainly accounts for the weight loss.
