ABSTRACT
ObjectiveTo analyze the measures and effects of comprehensive noise control in an automobile engine manufacturing enterprise. Methods An automobile engine manufacturing enterprise with noise exposure work-sites was selected as the research subject. The noise hazard status of the enterprise was investigated. The noise hazard exceeded the national standard in work-sites was comprehensively treated. The treatment effect was analyzed. Results A total of 395 work-sites exposed to noise were detected. Among them, 16 work-sites exceeded the national noise standard, with the rate of 4.1%. The work-sites with noise exceeding the national standard were mainly in the machine workshop and the casting workshop, with normalization of equivalent continuous A-weighted sound pressure level to a nominal eight hours working day (LEX,8h) ranging from 86.8 to 89.2 and 85.2 to 90.2 dB(A), respectively. In addition, the classification of occupational noise exposure of the mold protection group in the casting workshop was level Ⅱ, and classification of occupational noise exposure of other work-sites with excessive national standard was grade Ⅰ. After the enterprise implemented noise control measures such as process reform, equipment replacement, sound insulation, noise reduction, sound absorption, and vibration isolation, the LEX,8h of nine positions were lower than those before rectification [(86.7±1.1) vs (83.3±1.3) dB(A), P<0.01]. Conclusion The use of comprehensive control measures can achieve the purpose of reducing noise from the sources, and can be used for reference by relevant enterprises with noise hazards.
ABSTRACT

Esophagectomy is still the main treatment for locally advanced esophageal cancer. Ensuring the efficacy of oncology plays a crucial role in exploring organ preservation in the treatment of esophageal cancer. We should always be aware of the inherent difficulties and potential harms of organ preservation for esophageal cancer treatment and seek a personalized and reasonable balance between ensuring cure and preserving organs, provide the best treatment design for esophageal cancer patients, to achieve maximum therapeutic effect without sacrificing the life quality of patients.
ABSTRACT
Hepatocellular carcinoma is still a severe threat to people′s health of China. Most patients have advanced disease at the time of first diagnosis and lose the opportunity of radical surgery. In the past, the traditional medical drug treatment and radiotherapy are ineffective, which make the treatment of hepatocellular carcinoma into a bottleneck. With the emergence of target therapy represented as tyrosine kinase inhibitors and immunotherapy represented by programmed death-1 antibody and programmed death-ligand 1 antibody, the treatment of hepatocellular carcinoma has entered a new era and patients with advanced hepatocellular carcinoma have seen a new hope. The systemic therapy represented by target therapy and immunotherapy has not only greatly improved the survival of patients with advanced hepatocellular carcinoma, but also changed the treatment concept of hepatocellular carcinoma from single-drug therapy to combined therapy with multiple means. The treatment of hepatocellular carcinoma has changed from the era of surgery as the king to the era of surgery as the mainstay of whole-process management and comprehensive treatment. The authors review previous studies and their own experience to elaborate on the comprehensive treat-ment strategy for hepatocellular carcinoma based on surgical treatment in the era of targeted therapy and immunotherapy.

ABSTRACT
Objective:To investigate the treatment and prognosis of patients of G3 non-functional pancreatic neuroendocrine tumors (pNETs) with proliferation index of Ki-67 <55%.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 15 G3 non-functional pNETs patients with proliferation index of Ki-67<55% who were admitted to Zhongshan Hospital of Fudan University from April 2014 to April 2020 were collected. There were 11 males and 4 females, aged (58±10)years. All patients underwent radical resection of the primary lesion. Obser-vation indicators: (1) treatment; (2) postoperative pathological characteristics; (3) follow-up. Measure-ment data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( Q1, Q3) or M(range). Count data were described as absolute numbers. The Pearson correlation analysis was used to verify the correlation between variables. Kaplan-Meier method was used to draw survival curve and calculate survival rate. Log-Rank test was used for survival analysis. Results:(1) Treatment. All 15 G3 nonfunctional pNETs patients underwent radical resection of the primary lesion of pancreas, including 5 cases receiving pancreati-coduodenectomy, 10 cases receiving distal pancreatectomy with splenectomy. There were 5 patients with simultaneous liver oligometastasis who underwent combined segmental (lobectomy) hepatectomy. All 15 patients had negative tumor margin, and the operation time and volume of intraoperative blood loss of 15 patients was 120(90,210)minutes and 200(50,300)mL, respectively. None of patient had complications ≥Ⅲ grade of the Clavien-Dindo classification during the postoperative 30 days. Of the 15 patients, there were 5 cases receiving comprehensive treatment based on CAPTEM chemo-therapy (temozolomide combined with capecitabine), 2 cases receiving local interventional therapy, 2 cases receiving CAPTEM chemotherapy, 1 case receiving local interventional therapy combined with molecular targeted therapy, 1 case receiving local interventional therapy combined with long acting somatostatin therapy, 1 cases receiving long acting somatostatin therapy combined with molecular targeted therapy, and 3 cases without postoperative treatment. (2) Postoperative patholo-gical characteristics. The tumor diameter of 15 patients was 3.3(range, 0.5-6.0)cm. There were 2 cases with tumor diameter <2 cm, 13 cases with tumor diameter ≥2 cm. The number of lymph nodes dissected and number of lymph nodes metastatic was 6(4, 10) and 2(1,3) in 15 patients, respectively, including 12 cases with positive lymph node metastasis. Of the 15 patients, there were 5 cases with tumor invasion of adjacent organ, 5 cases with simultaneous liver metastasis, 8 cases with perineural invasion and 8 cases with vascular invasion. There were 3, 7, and 5 patients with stage Ⅱ, stage Ⅲ, and stage Ⅳ of pathological TNM staging, respectively. The proliferation index of Ki-67 and mitotic count was 32%±9% and (11±9)/10 high power field in the primary lesion of 15 patients, respectively, and there was no correlation between proliferation index of Ki-67 and mitotic count ( P>0.05). (3) Follow-up. All 15 patients were followed up after surgery for (55±24)months. The median survival time of 15 patients was 78(range, 43-113)months, with 1-, 3-, 5-year overall survival rate as 100%, 92%, 62%, respectively. During the follow up, 9 of the 15 patients underwent tumor recurrence, with the recurrence time as 20(14, 44)months. There were 8 patients died of tumor recurrence or metastasis. The median survival time was 86(range, 51-120)months in 5 patients receiving comprehensive treatment based on CAPTEM chemotherapy, versus 53(range, 45-60)months in 10 patients receiving other postoperative adjuvant therapy or without postoperative treatment, showing a significant difference between them ( χ2=4.21, P<0.05). Conclusion:The prognosis of patients of G3 nonfunctional pNETs with proliferation index of Ki-67<55% undergoing radical resection combined with postoperative comprehensive treatment based on CAPTEM chemotherapy in better than that of patients receiving other postoperative adjuvant therapy or without posto-perative treatment.
ABSTRACT
Objective:To summarize the clinical characteristics of 4 cases of mixed pituitary adenomas involving growth hormone(GH), prolactin(PRL), and thyroid stimulating hormone(TSH), and explore the standardized management approaches.Methods:The clinical data of four GH/PRL/TSH mixed pituitary adenoma patients diagnosed by Peking Union Medical College Hospital were retrospectively analyzed, including clinical manifestations, biochemical parameters, radiographic characteristics, as well as treatment and prognosis. Then literature review was conducted.Results:Among the 4 patients, 3 were male, with onset ages ranging from 15 to 38 years. All patients presented with coarse facial features as initial symptom. Three patients had visual impairment or visual field defects. All 4 patients had significantly elevated levels of GH and insulin-like growth factor-Ⅰ(IGF-Ⅰ). GH was not inhibited by oral glucose tolerance test. PRL concentration was over 100 ng/mL. Triiodothyronine(T 3)and thyroxine(T 4)were also elevated, while TSH was not inhibited. All pituitary adenomas in four cases were macroadenomas or giant adenomas, all of which were invasive growth, and one case developed pituitary stroke. Except for one patient who did not receive treatment in our hospital due to medical expenses, the remaining three patients underwent a combined treatment of medication and transnasal transsphenoidal pituitary adenoma resection. Among them, one patient had relief of central hyperthyroidism and hyperprolactinemia, but GH/IGF-Ⅰ did not meet the remission criteria. The other two patients had persistent non-resolution of at least 2 hormone axes. Conclusions:Patients with GH/PRL/TSH mixed pituitary adenoma were mainly characterized by coarse facial features, GH/PRL/TSH hyperfunction, large adenoma volume, low biochemical remission after surgery combined with drug treatment, and poor clinical prognosis.
ABSTRACT
Objective:To evaluate the efficacy and safety of comprehensive treatment for retinoblastoma (RB).Methods:A retrospective clinical study. From January to December in 2019, 157 cases (203 eyes) of RB who were diagnosed by the Department of Ophthalmology of Xinhua Hospital and received comprehensive treatment were included in this study. Of cases, 76 were male, and 81 were female; 111 were unilateral, and 46 were bilateral. The medium of age at diagnosis was 20.1 months. All patients received treatment for the first time. Patients with intraocular tumors were divided into A-E stages, extraocular stage and distant metastasis according to international intraocular RB classification standard. The median follow-up time was 37.4 months. Clinical features, treatment, prognosis and ocular complications of all cases were recorded.Results:Among 157 cases (203 eyes), 137 cases (180 eyes) were in intraocular stage; 6, 14, 10, 98, and 52 of eyes were in A-E stages, respectively. Twelve cases (12 eyes) were in extraocular stage; 8 cases (11 eyes) were in distant metastasis stag; 8 cases died due to distant metastasis; 149 cases (94.9%, 149/157) survived; 48 eyes were enucleated, 34 of which underwent initial enucleation, and 14 eyes underwent enucleation after eye-preserving treatment. The overall global salvage rate was 155 eyes (76.4%,155/203), and that after eye-preserving treatment was 91.7% (155/169). Severer eye for bilateral cases was taken into account for statistic; 120 cases (120 eyes) received initial eye-preserving treatment. Among them, 36 and 84 eyes underwent initial intravenous chemotherapy (IVC) and initial intra-arterial chemotherapy (IAC), respectively. The enucleation of the two groups was 7(19.4%, 7/36), 7(8.3%, 7/84); 33 (91.7%, 33/36) and 33 (39.3%, 33/84) eyes received the second treatment, respectively. There was no significant difference in the rate of enucleation between the two treatments ( χ2=2.037, P=0.154). There was significant difference in the percentage of secondary treatment ( χ2=27.937, P<0.001). Fifty-four eyes (45.0%, 54/120) stabilized after initial treatment, and 66 eyes (55.0%, 66/120) underwent secondary treatments due to poor response or tumor recurrence. For 66 eyes receiving secondary treatments, enucleation, IAC, intravitreous chemotherapy (IVitC), IAC combined with IVitC, and laser and/or cryotherapy was performed in 6, 18, 12, 13, and 17 eyes, respectively. The number of eyes of enucleation among the IAC, IVitC, and IAC combined with IVitC group was 5 (27.8%, 5/18), 1 (9.3%, 1/12), and 2 (15.4%, 2/13) eyes, which was no significantly different ( χ2=2.001, P=0.368). Until the last follow-up, visual acuity outcomes were acquired in 148 eyes (72.9%, 148/203). Among them, 41, 53, 16 and 38 eyes had no light perception, light perception to finger counting, 20/400, and ≥20/200, respectively. In total, among 203 eyes, 121 eyes received IAC, of which 2, 4, and 1 eyes had optic disc atrophy, vitreous hemorrhage, and severe retinal-choroidal atrophy, respectively; 60 eyes received IVitC, of which one and one eye had vitreous hemorrhage and macular hemorrhagic necrosis, respectively. Conclusions:In this study, the overall survival rate was 94.9% after comprehensive treatment and the rate of global salvage after eye-preserving treatment was 91.7%. The comprehensive treatment of retinoblastoma had a relatively high efficacy and safety.

ABSTRACT
Objective:To analyze long-term outcomes of inoperable non-metastatic pancreatic cancer patients treated with definitive radiotherapy-based comprehensive treatment.Methods:Clinical data of 168 patients with medically unfit, refusal to surgery or inoperable non-metastatic pancreatic cancer treated with radiotherapy-based comprehensive treatment in PLA General Hospital between January 2016 and December 2020 were retrospectively analyzed. Survival outcomes,prognostic factors and patterns of treatment failure were analyzed in the radiotherapy ( n=95) and combined chemoradiotherapy ( n=73) groups. The survival analysis was conducted by Kaplan-Meier method. The survival curve was compared by log-rank test. Independent prognostic factors were identified by Cox proportional harzard model. Results:With a median follow-up of 20.2 months in the entire group, the median overall survival (OS) and median progression-free survival (PFS) were 18.0 and 12.3 months. The corresponding median OS and median PFS after receiving radiotherapy were 14.3 and 7.7 months. The 1-, 2-and 3-year OS rates were 72.1%, 36.6% and 21.5%, and the 1- and 2-year local control rates were 82.6% and 64.3%, respectively. The median OS for stage Ⅰ, stage Ⅱ and stage III were 27.1, 18.0 and 17.0 months, respectively. There was no significant difference in the median OS of patients with localized disease (stage Ⅰ-Ⅱ) between the radiotherapy and combined chemoradiotherapy groups (21.1 vs. 20.4 months, P=0.470). In patients with locally advanced disease (stage Ⅲ), combined chemoradiotherapy group showed better median OS compared with radiotherapy group (19.2 vs. 13.8 months, P=0.004). Clinical stage, CA19-9 before radiotherapy, comprehensive treatment and biological effective dose (BED 10) were identified as the independent prognostic factors for OS ( P=0.032, 0.011, 0.003 and 0.014). The cumulative 1- and 2-year actuarial rates of treatment failure, local-regional recurrence and distant metastasis were 48% and 74.4%, 15.0% and 27.4%, 23.6% and 33.1%, respectively. Liver metastasis (16.1%, 27/168) and local recurrence (11.9%, 20/168) were the primary patterns of treatment failure. Conclusions:Definitive radiotherapy-based comprehensive treatment effectively prolongs long-term survival in patients with inoperable non-metastatic pancreatic cancer. Definitive radiotherapy can be an alternative treatment option with curative intent for patients with localized pancreatic cancer who are medically unfit or refuse to undergo surgery. The combination of radiotherapy and chemotherapy remains an effective treatment choice for locally advanced unresectable pancreatic cancer.
ABSTRACT
Objective:To explore different strategies of central repair first or malperfusion first to treat type A aortic dissection complicated with limb malperfusion.Methods:From January 2020 to December 2021, 302 patients were diagnosed with acute type A aortic dissection, and 17 consecutive patients were diagnosed as type A acute aortic dissection complicated with limb malperfusion and underwent Sun’s procedure. There were 16 males and 1 female with an average of(52.6±4.2)years. Surgical strategies were as follows: immediate central repair-Sun’s procedure in 14 patients, endovascular stenting followed by central repair in 3 patients, endovascular stenting after central repair in 1 patient.Results:The incidence rate of limb malperfusion of acute Stanford A aortic dissection was 5.6%(17/302). Average extracorporeal circulation time was(271.8±38.9)min, average aortic cross-clamp time was (186.3±31.8)min, and the average circulatory arrest time was (48.75±11.3)min. Early mortality rate was 17.6%(3/17). Two patients were left hospital voluntarily because of cerebral infarction. One patient underwent leg incision osteofascial compartment syndrome and discharged unevently. Five patients underwent continuous renal replacement therapy and hemoperfusion. Follow-up results showed that patients with serious limb malperfusion have symptoms of nerve dysfunction including amyosthenia and sensory disturbance, but recovered gradually with rehabilitation.Conclusion:Sun’s procedure is safe and feasible for type A acute aortic dissection complicated with mild limb malperfusion. For serious limb malperfusion, endovascular stent followed by Sun’s procedure is a good choice with CRRT and hemoperfusion.
ABSTRACT
Biliary tract cancers (BTC) is a type of digestive tract malignant tumors that originate from biliary epithelial cells, is characterized by strong occult and highly invasive, and has a high mortality rate. Early detection and diagnosis are considered to be the key to obtaining radical surgical treatment. R0 resection is an effective measure to benefit patients with BTC. However, most of the patients present with local progression or associated distant metastasis, making it impossible to undergo radical surgical treatment. With existing diagnosis and treatment methods, the 5-year survival rate of patients is still very low. Therefore, how to improve the level of diagnosis and treatment of BTC, prolong survival, and improve the quality of life has become an urgent problem to be solved. In view of the characteristics of BTC and the continuous deepening of clinical pathological molecular research, adjuvant therapy, precisely targeted therapy, immunotherapy, and comprehensive treatment are currently considered to be standardized diagnosis and treatment models and research directions beyond surgery. Therefore, this article systematically analyzes the current research progress of BTC both domestically and internationally, aiming to provide strategies for the diagnosis and treatment of patients with BTC.
ABSTRACT
Objective:To explore the effectiveness and safety of comprehensive treatment of type 2 diabetes mellitus (T2DM) based on syndrome differentiation and diet.Methods:Prospective clinical study. A total of 147 patients with T2DM from September 2021 to August 2022 who met the inclusion criteria were included in the self-controlled trial. On the basis of diet and exercise intervention, the subjects were treated and observed with comprehensive treatment based on syndrome differentiation for 120 days. The main outcome indicators including TCM symptom score, fasting blood glucose (FPG), 2 hPG, HbA1c , Fasting insulin (FINS), C-peptide(C-PR), and the secondary outcome indicators including blood lipid (TC, TG, HDL-C, LDL-C), blood pressure, and safety indicators were performed before and after treatment.Results:After treatment, the FPG of subjects decreased from (8.75±2.26) mmol/L to (7.05±1.23) mmol/L, 2 hPG decreased from (10.75±3.01) mmol/L to (7.07±0.78) mmol/L, HbA1c decreased from (6.82±1.47)% to (5.49±0.63)%, and FINS decreased from (15.4±9.33) μIU/ml to (8.82±7.28) μIU/ml, C-PR decreases from (1.95±0.91) nmol/L to (1.72±1.53) nmol/L, SBP decreased from (137.51±17.94) mmHg to (125.79±7.57) mmHg, DBP decreased from (82.85±9.65) mmHg to (77.54±6.21) mmHg,TG decreased from (1.57±1.04) mmol/L to (1.25±1.24) mmol/L, HDL-C increased from (1.48±0.41) mmol/L to (1.66±0.46)mmol/L. The above differences were statistically significant ( P<0.05). Conclusion:The comprehensive treatment of T2DM based on syndrome differentiation and diet can significantly reduce the blood glucose indicators including FPG, 2 hPG, HbA1c, FINS and C-PR, and benefit blood pressure and blood lipids with no adverse reactions.
ABSTRACT
Esophageal cancer is one of the common malignant tumors in the worldwide and has regional characteristics in China. At present, the treatment of esophageal cancer is still a comprehensive diagnosis and treatment mode based on surgery. With the application of minimally invasive technique in surgery of esophageal cancer, the concept of surgical diagnosis and treatment for esophageal cancer is constantly updating. The application of robotic surgical system in esophageal surgery promotes the surgical quality of lymph node dissection and improves the technique of intraluminal anastomosis under total endoscopy. For locally advanced esophageal cancer, a diagnosis and treatment mode based on neoadjuvant therapy has been gradually accepted by most of doctors around China. Combined with the latest researches at home and abroad, the authors investigate the development of surgical techniques, the renewal of surgical concept and the changes on diagnosis and treatment, summarize the new advances in comprehensive surgical treatment for esophageal cancer, in order to provide the theoretical guidance for the standardized treatment of esophageal cancer.
ABSTRACT
Comprehensive treatment of biliary tract cancer has evolved rapidly, thereby improving disease control and long-term survival. The authors focus on the update of this emerging field and its impacts on surgical treatment to explore the development of surgery in the treatment of biliary tract cancer in the future. With the goal of medium- and long-term benefits, a comprehensive treat-ment based on multidisciplinary team and surgery-centered approach is recommended throughout treatment of biliary tract cancer. In the era of multidesciplinary team, surgical treatment of biliary tract cancer will develop toward precision, limited surgical scope, and minimally invasive technique.
ABSTRACT
With the deep understanding of gastric cancer and the development of new technology, various comprehensive treatment modes for different stages of gastric cancer have been widely recognized. Endoscopic technology represented by endoscopic submucosal dissection is an important method for diagnosis of gastric cancer and treatment for early gastric cancer. Surgical operation is the preferred treatment for locally advanced gastric cancer, mainly including total gastrectomy, distal gastrectomy, pylorus preserving gastrectomy, proximal gastrectomy and the corresponding regional lymph node dissection. Neoadjuvant chemotherapy, adjuvant chemotherapy and hyperthermic intraperitoneal chemotherapy play important roles in preoperative and post-operative adjuvant therapy of gastric cancer, while the role of radiotherapy needs to be further observed. In recent years, targeted therapy represented by trastuzumab which is positive for human epidermal growth factor receptor-2 and immunotherapy represented by programmed death-1 inhibitors have made important progress in the treatment of gastric cancer. However, they need to be further proved to become the first-line treatment for gastric cancer. The authors believe that with more research results of gastric cancer, the comprehensive treatment of gastric cancer will be more diversified, which will make the treatment of gastric cancer individualized and accurate and finally benefit more patients.
ABSTRACT

In recent years, the concept of 'total neoadjuvant therapy' has become one of the important treatment methods for locally advanced rectal cancer. The authors focus on pancrea-tic cancer, introduce the development status of total neoadjuvant therapy in pancreatic cancer and summarize the current controversies and challenges in the application of total neoadjuvant therapy in pancreatic cancer, in order to further standardize the diagnosis and treatment of pancreatic cancer and improve the overall level of pancreatic cancer treatment in China.
ABSTRACT
Objective:To summarize the surgical treatment experience of extended thymectomy for myasthenia gravis(MG), and to explore the surgical treatment of MG.Methods:Retrospectively analyzed the clinical data of 527 MG patients undergoing extended thymectomy in our hospital from June 1996 to October 2017, including 242 males and 285 females, aged 5 to 77 years, with a mean age of(52.6±13.7) years old. The course of illness was 12 days to 18 years. There were 22 cases of hyperthyroidism, 7 cases of pure red blood cell aplastic anemia, 1 case each of hypothyroidism, irritable bowel disease, rheumatoid arthritis, ankylosing spondylitis and thrombocytopenia syndrome. There were 272 cases of MG in Osserman Ⅰ, 72 cases inⅡa, 78 cases inⅡb, 81 cases in Ⅲ, and 24 cases in Ⅳ, respectively. The muscle fatigue test and neostigmine test of all patients were positive, and the diagnosis was confirmed by chest CT examination. Meanwhile, summarize the perioperative data and postoperative follow-up.Results:3 cases died during the postoperative period, all of which were thymoma with MG, including 2 cases of Osserman Ⅲ MG and 1 case of Ⅳ MG; 15 cases of postoperative myasthenia crisis, including 2 OssermanⅡb cases, 11 Osserman Ⅲ cases and 2 Osserman Ⅳ cases, also including 7 cases of tracheotomy; 70 cases of plasma exchange, of whom 2 cases of hypotonic syndrome and 2 cases of lower extremity venous thrombosis. The postoperative pathological types were followed by thymic hyperplasia 293 cases(55.60%), thymoma 207 cases(39.28%), thymic cyst 24 cases(4.55%) and thymic atrophy 3 cases(0.57%) in descending order. 378 cases were followed up with an average follow-up of(85.9±58.5)months; MG with complete remission, partial remission, no change and deterioration accounted for 135(35.71%), 192(50.79%), 41(10.85%) and 10(2.65%)cases, respectively. Complete remission rate ranked as Osserman typeⅠ>Ⅱa>Ⅳ>Ⅱb>Ⅲ, the deterioration rate from high to low was Osserman type Ⅲ>Ⅳ>Ⅰ. 18 OssermanⅠcases showed no effects, whose preoperative course of disease> 5-10 years; 1 OssermanⅠcase was worsening who initially was diagnosed with ophthalmic MG and underwent video-assisted thoracoscopic thymectomy. The left thymus lobe was left unresected and developed 6 years later. Another operation was performed to remove the left lobe thymus, confirming the compensatory hypertrophy of the left lobe thymus. Among the worsening patients, 6 died, all of them were thymoma with MG, including 5 cases of type Ⅲ and one case of type Ⅳ. The cause of death was omyasthenia crisis(3 cases), sudden respiratory arrest after 3 months of rapid stopping of brompistigmine(2 cases)and cholinergic crisis(1 case).Conclusion:Standardized extended thymectomy is an effective method for the treatment of MG. Earlier surgery for ocular muscle type MG can effectively reduce the risk of generalization. MG with Osserman Ⅱb or higher is prone to myasthenia crisis. Comprehensive treatments should be taken to reduce MG-related risks. Myasthenia crisis can occur repeatedly in severe patients in the long term after surgery, requiring regular medication and comprehensive MG treatments.
ABSTRACT
At present, surgical resection remains as the main treatment for patients with colorectal cancer (CRC). Alongside the progress in oncologic surgical technique, minimally invasive approaches, such as laparoscopy and transanal total mesorectal excision (taTME), and individualized surgical options, such as lateral lymph node dissection and multivisceral resection, the patient mortality associated with traditional surgical approaches has been improved. Neoadjuvant therapy can decrease local recurrence and distant metastasis, and improve the survival of patients. The optimization of adjuvant therapy shortens treatment cycle, reduces treatment risk and toxicities. Recently, neoadjuvant immunotherapy has become the new standard of the treatment for mismatch repair-deficient or microsatellite instability high CRC. However, it shows unsatisfactory outcomes in patients with mismatch repair-proficient/microsatellite stable CRC, which needs overcoming the limi-tation of CRC genephenotype. With more researches on CRC, the more biomarkers predicting the response to treatment will be found and the novel comprehensive treatment of CRC will be developed, which will make the treatment of CRC more individualized and accurate, and finally benefit more patients.
ABSTRACT
A greater controversy remains in clinical diagnosis and treatment of Siewert type II adenocarcinoma of esophagogastric junction (AEG), compared with Siewert type I and III AEG. In 2018, the first edition of Chinese Expert Consensus on the Surgical Treatment for Adenocarcinoma of Esophagogastric Junction was published in the Chinese Journal of Gastrointestinal Surgery. In the past few years, the advance in minimally invasive thoracoscopic surgery has been proven to reduce thoracic trauma in Siewert type II AEG. Meanwhile, distal thoracic esophagectomy can achieve more complete resection, and upper abdomen-right thoracic approach can ensure the mediastinal lymph node dissection and improve long-term survival. The concept and practice of endoscopic surgery and the comprehensive treatment also give new supplements to the treatment regimen of Siewert type II AEG. More clinical researches should be conducted to address the surgical residual safety and lymph node dissection issues.

Bladder cancer(BC) ranks the first of genitourinary tumor in China and is one of the most common urological malignancies, in which 25%-30% of patients were diagnosed with muscle-invasive bladder cancer. Radical cystectomy combined with pelvic lymph node dissection is the standard procedure for treatment, which can effectively avoid tumor recurrence or distant metastasis as well as improve the prognosis of patients. However, some patients may not tolerate or refuse to undergo radical bladder surgery due to worry about high complication rate, high morbidity and poor postoperative quality of life. With the increasing understanding of bladder cancer heterogeneity and biological behavior, the treatment of bladder cancer has changed from a surgery-based treatment model to an individualized and comprehensive treatment model by multidisciplinary collaboration. The bladder-preserving treatment can achieve the same oncological prognosis as that of radical bladder surgery with a better quality of life of the patients, which has become a hot topic and focus of research in muscle-invasive bladder cancer treatment. This article reviewed the progress of research related to the comprehensive treatment of muscle-invasive bladder cancer with preservation of the bladder.
