Systematic treatment of breast cancer can reduce the risk of recurrence and prolong the survival，which has been widely recognized in clinical practice. Chemotherapy for breast cancer patients often contains corrosive drugs. According to the Health Industry Standard of China，corrosive drugs should not be infused through peripheral vein. In order to standardize the clinical application of chemotherapy infusion pathway，the Chinese Society of Breast Surgery（CSBrS）issued the Clinical Practice Guide for Central Venous Access for breast cancer，and recommended totally implantable venous access port as a safe infusion access for chemotherapy. Due to the safe operation precedure and low incidence of serious complications such as pneumothorax and hemothorax，implantable venous access port via basilic vein can be used as one of the options for chemotherapy infusion pathway.

The Chinese Medical Association's Clinical Practice Guide for Breast Surgery（2022）added a new chapter of clinical practice guideline about postoperative lymphedema of breast cancer. According to the Evidence-Based Medical evidences of diagnosis and treatment of postoperative lymphedema of breast cancer，referring to the GRADE standard and following the principle of clinical diagnosis and treatment accessibility，this guideline present recommendations on the high-risk population，diagnosis，staging，treatment and postoperative rehabilitation of postoperative lymphedema of breast cancer in grades. In this paper，combined with practical clinical experience，the key contents of the guideline are interpreted for the reference of relevant people.

The Nipple-sparing Mastectomy combined with Tissue Expander Implantation and Axillary Lymph Node Dissection with Lateral Mini-incision has been performed by our team since 2016，with more than 200 cases completed. This surgical method balances safety and aesthetics，improves surgical efficiency，and the therapeutic effect was satisfactory without significant complications. Firstly，a slightly curved arc incision is selected on the outside of the areola，extending no more than 6 cm in length. The breast skin flap is freed with an electrosurgical scalpel，and the posterior margin of the nipple is excised with a scalpel to check for cancer invasion by intraoperative frozen pathology. The breast gland is then excised from the surface of the pectoralis major，and the axillary lymphatic fatty tissue（Level Ⅰ andⅡ）is dissected using an ultrasonic scalpel. Subsequently，the tissue behind the pectoralis major is freed，and the lateral end of the pectoralis major rib is cut. After confirming that there is no cancerous infiltration on the cut margin behind the nipple，the tissue expander is placed using the dual-plane method to construct the cavity. Finally，two drainage tubes are left in place，and the incision is sutured layer by layer.

Laparoscopic surgery has been widely utilized in the treatment of rectal cancer. Considering the predominance of low and ultra-low rectal cancer in China，the rational selection of surgical approaches to achieve both tumor eradication and functional preservation is a clinically significant issue that warrants in-depth investigation. There is a wide range of laparoscopic techniques available for low rectal cancer，necessitating careful preoperative evaluation and precise determination of indications for neoadjuvant therapy. The fundamental objective should be achieving oncological clearance while ensuring appropriate selection of sphincter-preserving procedures. The choice of surgical approach should be personalized according to individual patient characteristics.

Laparoscopic anterior resection for low rectal cancer with preservation of the left colonic artery，following the principles of TME and neural function preservation，aims to maximize anastomosis blood supply and maintain autonomic neural function. The surgery has significant advantages in reducing surgical complications and accelerating recovery.The surgical procedure involves a five-port technique under endotracheal intubation and general anesthesia. Firstly，the sigmoid colon is dissected from the lateral abdominal wall，then the sigmoid mesocolic gutteris exposed. The dissection proceeds to the right side of the mesentery，entering the Toldt’s space in front of the sacroiliac promontory. The superior rectal artery，the superior mesenteric artery，and the left colonic artery are carefully dissected，and 253 lymph nodes are dissected. The superior rectal artery is ligated and divided according to the principles of TME. The rectum and its mesentery are separated until reaching the level of the pelvic muscle，with the Denonvilliers fascia and the lateral ligaments of the rectum being preserved to protect the vascular and nerve bundles. The rectum is divided at least 2 cm distal to the tumor.A transverse incision is made in the lower left abdomen，and the mesentery of the colon is dissected and the specimen is removed. The proximal end of the colon is placed the stapler seat，and pneumoperitoneum is reestablished. The rectal-colonic anastomosis is created under direct visualization.

Clinical practice China guidelines on central venous vascular access for breast cancer（2022 edition）was made by the experts of the Chinese Society of Breast Surgery（CSBrS）of the Chinese Medical Association organized. The purpose of the guideline was to standardize application of CVA in the clinical practice of breast cancer patients. There has differences among different CVA when they used for breast cancer patients. We mainly interpret the indications and contraindications of different CVAs，channel selection，prevention and treatment of complications and maintenance of different CVAs in the guidelines.

（1）Incision. It is recommended to use the parallelogram method or S shape，inside to the left margin of the sternum，outside to the anterior axillary line no more than the anterior axillary line，about 1cm above the lower margin of the clavicle，and about 1cm below the upper margin of the costal arch.（2）Cold knife peel the flap. Flap dissociation should be carried out in the superficial layer of the superficial fascia of the breast tissue，and the subdermal vascular network should be preserved during the separation process. As far as possible，low output power should be selected to reduce thermal damage.（3）glandulectomy. After the completion of flap dissociation，glandular tissue was separated from the pectoralis major muscle，and the peeled glands were wrapped with clean gauze，which was conducive to axillary dissection and enlargement. Intraoperative damage to pectoralis major fibers should be avoided，and attention should be paid to ligation or electrocoagulation of the perforator artery of the internal thoracic artery and many small perforator vessels from the pectoralis major muscle.（4）axillary lymph node staging. The protective axillary vein was separated and its branches ligation. After the third level lymph nodes were dissected by bipolar electrotome，the axilla was dissected to protect the long thoracic nerve and the thoracolumdoric nerve.（5）Interthoracic lymph node dissection（Rotter lymph node）：sharp separation of the space between the large and small thoracic muscles to complete lymph node dissection in this region.（6）Careful hemostatic irrigation. One porous drainage tube was placed under the axilla and one beside the sternum，and the suction tube was in a negative pressure state.

Laparoscopic techniques have become popular for the surgical treatment of gastric cancer and are used for many procedures. However，intracorporeal esophagojejunostomy during laparoscopic total gastrectomy is technically challenging. Various methods of intracorporeal anastomosis for esophagojejunostomy have been applied. However，anastomosis with a circular stapler is troublesome and requires special equipment for purse-string suture and anvil insertion. However，anastomosis methods using linear staplers require advanced techniques and numerous staplers. Totally，π-shape reconstruction（3-in-1 procedure for esophagojejunostomy）is widely used.

Laparoscopic technology has been developed in colorectal surgery in China for 30 years. The key to the success of this technology is standardized technical practice and standardized technical promotion. The incidence of rectal cancer，especially mid and lower rectal cancer，is relatively high in China，and because of the special anatomical position，it is more involved in functional preservation. Therefore，the standardization of laparoscopic surgery is more important for radical resection of rectal cancer. This article elaborates on the standardized development of laparoscopic surgery for rectal cancer in China from the aspects of surgical indications，standardized promotion of technology，systematic training，and further standardization of technological innovation.

The first choice of treatment for de novo stage Ⅳ breast cancer is systemic therapy based on molecular typing. Thanks to the rapid iteration of new anti-cancer drugs and the popularization of clinical application of genetic testing tools，the survival time and quality of life of patients with de novo stage Ⅳ breast cancer have been greatly improved，and the principles of local surgical treatment have become a hot issue of clinical concern. Based on this，the Chinese Society of Breast Surgery took the lead and conducted a discussion on the key issues in the diagnosis and treatment of de novo stage Ⅳ breast cancer，developed the clinical practice guidelines for diagnosis and treatment of de novo stage Ⅳ breast cancer（2022 edtition）.

Recently，with the increasing proportion of adenocarcinoma of esophagogastric junction and upper third gastric cancer，and the maturity and wide application of laparoscopic technology，the digestive reconstruction after laparoscopic total gastrectomy has become a technical hotspot and difficulty in gastric cancer surgery. The selection strategy of reconstruction mode is still worth discussing. Based on the available evidence，the reconstruction strategy is suggested as follows. The use of linear stapler for related digestive reconstruction has certain advantages. Posterior disconnection has certain advantages in technical operation，but its indications should be paid attention to. Anteperistalsis and antiperistalsis can be selected according to the surgeon’s habits. Roux-en-Y anastomosis without pouch is the main reconstruction.

To analyze the effects of one-and two-step breast reconstruction on patient reported outcomes and complications.

A total of 98 patients who underwent immediate breast reconstruction after total mastectomy from March 2017 to March 2022 were selected and divided into two groups according to different reconstruction methods：the one-step group received 50 cases of immediate prosthesis implantation reconstruction surgery，and the two-step group received 48 cases of immediate dilator-delayed prosthesis implantation reconstruction surgery. SPSS 21.0 software was used to analyze the data，and the count data were compared by line χ² test or Fisher exact test. Measurement data were represented by（

The incidence of seroma and poor wound healing in one-step group was higher than that in two-step group，and the incidence of capsular contracture was lower than that in two-step group（P<0.05）. The number of Clavien-Dindo grade Ⅲ cases in one-step group was higher than that in two-step group（P<0.05）. The levels of postoperative social mental health，breast satisfaction and surgical outcome satisfaction in one-step group were lower than those in two-step group（P<0.05）. The results of linear mixed effects regression model showed that the poor wound healing was related to the surgical method and the use of mesh（P=0.043，0.033）. Capsular contracture and seroma were related to radiotherapy and mesh use（P=0.041，0.036）. Social psychological health and breast satisfaction were correlated with surgical methods（P=0.024，0.001）. The satisfaction of surgical outcome was related to postoperative radiotherapy and lymph node status（P=0.017，0.039）.

Compared with one-step breast reconstruction，two-step method can reduce the incidence of poor incision healing，lower complication grade，and has more advantages in improving patients' postoperative social psychological satisfaction and breast satisfaction.
