[Long-term efficacy of robotic radical total gastrectomy for gastric cancer and analysis of prognostic factors].
Objective: To analyze long-term outcomes and prognostic factors of gastric cancer patients after robotic radical total gastrectomy. Methods: A retrospective case-control study was conducted. Inclusion criteria: (1) receiving robotic radical total gastrectomy; (2) gastric adenocarcinoma was confirmed by postoperative pathology; (3) no previous history of other malignant tumors; (4) no preoperative chemotherapy or radiation therapy performed. ⋯ Multivariate analyses revealed that TNM stage (P<0.001; stage IIIB: HR=5.357, 95%CI:1.182 to 24.275; stage IIIC: HR=11.937, 95%CI: 2.677 to 53.226) and number of harvested lymph nodes at group 2 (P=0.034; 6-10: HR=0.562,95%CI:0.326 to 0.969; >10: HR=0.388, 95%CI: 0.176 to 0.857) were independent prognostic factors for overall survival. Conclusion: The long-term outcomes of robotic radical total gastrectomy were satisfactory. TNM stage and number of harvested lymph nodes at group 2 were independent prognostic factors for overall survival.

[Standardized diagnosis and treatment of colorectal cancer during the outbreak of corona virus disease 2019 in Renji hospital].
Corona virus disease 2019 (COVID-19) is currently raging in China. It has been proven that COVID-19 can be transmitted from human to human and cause hospital infection, which seriously threatens surgical staffs and inpatients. Although colorectal surgery is not a front-line subject in the fight against the epidemic, but in this special situation, it is a difficult task to provide the highest quality medical services and ensure the orderly clinical work, on the premise of maximizing the protection for patients and their families, health of medical staff, and the safety of wards and hospitals, We summarize how to carry out the clinical practice of colorectal surgery under the situation of the prevention and control of the COVID-19 epidemiology, including the procedures of diagnose and treatment for emergency patients with colorectal tumor, and share the experiences of the diagnosis of colorectal tumor, the management of patients with colorectal cancer who are scheduled to be admitted for surgery, the protection of wards, the perioperative management. ⋯ All disposable medical items, body fluids and feces of the patients in perioperative periods must be unified disposed according to the medical waste standard. (4) The surgical medical workers who process colorectal cancer patients with COVID-19 must be protected by three-level. After operation, the medical workers must receive medical observation and be isolated for 14 days. We hope our "Renji experience" will be beneficial to colleagues.

Comparative Study[Comparison of short-term efficacy and perioperative safety between neoadjuvant therapy and total neoadjuvant therapy in patients with locally advanced rectal cancer].
Objective: To compare the short-term efficacy and perioperative safety of neoadjuvant chemoradiotherapy (nCRT) with total neoadjuvant treatment (TNT) in patients with locally advanced rectal cancer (LARC). Methods: A retrospective cohort analysis was carried out. Inclusion criteria: (1) rectal adenocarcinoma confirmed by pathology with a distance from tumor inferior border to anal verge within 12 cm; (2) clinical stage cT3-4N0 or cT1-4N1-2 diagnosed by magnetic resonance imaging (MRI) or endorectal ultrasonography; (3) a single rectal tumor confirmed by colonoscopy; (4) patients suitable for chemoradiotherapy; (5) no previous history of other tumors. ⋯ Seventeen patients in the TNT group 22.4% (17/76) got pathologic complete response (pCR), which was significantly higher than 7.4% (4/54) in nCRT group (χ(2)=5.217, P=0.022). There were no statistically significant differences in ypTNM classification, perineural invasion and venous invasion between the two groups (all P>0.05). Conclusion: The pCR of TNT is higher than that of nCRT without increasing the incidence of toxicity and complications of radiotherapy and chemotherapy for patients with locally advanced rectal cancer.

[Rectum-preserving surgery after consolidation neoadjuvant therapy or totally neoadjuvant therapy for low rectal cancer: a preliminary report].
Objective: To investigate the feasibility and safety of sphincter-preserving surgery after neoadjuvant chemoradiotherapy (nCRT) with consolidation chemotherapy in the interval period or total neoadjuvant therapy (TNT) for low rectal cancer. Methods: A descriptive case series study was carried out. Clinical data of patients with locally advanced low rectal cancer (LALRC) who achieved complete clinical response (cCR) or nearly cCR (near-cCR) after nCRT at the Department of Colorectal Surgery of Fujian Medical University Union Hospital from May 2015 to February 2019 were retrospectively analyzed. ⋯ At present, 31 patients still survived. Conclusions: After nCRT with consolidation chemotherapy or TNT for low rectal cancer, patients with cCR, ycN0 according to PET-CT and MRI, and ypT0 after local excision, can consider the W&W strategy. Strict patient selection with a near-cCR for local resection and sphincter-preserving strategy can reduce the local regrowth of cancer, and the short-term outcomes are satisfactory.

Comparative Study[Comparison of long-term efficacy between watch and wait strategy and total mesorectal excision in locally advanced rectal cancer patients with clinical complete response after neoadjuvant therapy].
Objective: To compare long-term efficacy between watch and wait (W&W) strategy and total mesorectal excision (TME) in patients who were diagnosed with locally advanced rectal cancer (LARC) and attained clinical complete response (cCR) after neoadjuvant chemoradiotherapy (nCRT). Methods: A retrospective cohort study was carried out. A total of 238 patients with stage II-III LARC exhibiting cCR after nCRT in Sun Yat-sen University Cancer Center from September 16, 2010 to January 9, 2018 were enrolled. ⋯ When distance of tumor from the anal verge was ≤ 5 cm, the sphincter preservation rate (SPR) in the W&W group was 88.0% (44/50), which was significantly higher than the 54.4% (56/103) in the TME group (P<0.001). Conclusions: W&W is safe and feasible for patients with LARC and cCR after nCRT. The results should be verified by further clinical trials.
