Objective:This study aimed to evaluate the clinical features and treatment outcomes of the value of response-adapted treatment following radiotherapy and induction chemotherapy follwing subsequent comprehensive therapy in patients with resectable locally advanced hypopharyngeal carcinoma. Methods:This cohort study was conducted from September 2010 to September 2020 in our hospital, 231 patients pathologically confirmed stage Ⅲ and ⅣB resectable locally advanced hypopharyngeal carcinoma included. For the IC-directed ART strategy, IC is used to select good candidates to receive radical RT or CCRT, and others undergo surgery. He response-adapted strategy was determined based on the primary tumor response, which was evaluated at a dose of 50 Gy. If the response reached complete response or partial response(more than 80% tumor regression), patients received radical RT or CCRT; otherwise, they received surgery, if possible, at 4 to 6 weeks after RT. The end points of the study were OS(overall survival), progression free survival(PFS), locoregional recurrence-free survival(LRRFS) and LDFS. Results:In IC-directed group, 75.0%(57/76) patients reached PR after 2 cycles of induction chemotherapy. While in RT-directed group, 70.3%(109/155) patients reached large PR at dose of 50 Gy. The median interquartile range follow-up period of the whole cohort was 63.8 months. The 5-year OS, PFS, LRRFS and SFL of the whole cohort were 47.9%、39.6%、44.3% and 36.2%, respectively. In evaluations based on the different treatment strategies, the 5-year OS and SFL were 51.3% versus 37.0%(HR 0.67; 95%CI 0.43-1.05; P=0.07) and 27.8% versus 39.8%(HR 0.68; 95%CI 0.46-0.99; P=0.04) between IC-directed and RT-directed groups. In additional, surgery complications did not significantly differ between these two groups. Conclusion:In this cohort study, the response-adapted strategy based on an early RT response facilitated better treatment tailoring, and higher laryngeal preservation compared with IC-directed strategies. This approach could provide a feasible laryngeal preservation strategy in patients with resectable locally advanced hypopharyngeal carcinoma.

Objective:To investigate the application value of Da Vinci robotic surgical system in radical resection of perihilar cholangiocarcinoma (pCCA).Methods:The retrospective and descrip-tive study was conducted. The clinicopathological data of 10 patients undergoing Da Vinci robotic radical resetion of pCCA in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from September 2018 to March 2021 were collected. There were 6 males and 4 females, aged (58±7)years. Observtaion indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. The patients were followed up by telephone interview and outpatient service to detect survival of patients and tumor recurrence up to June 2021. Measurement data with normal distribution were expressed as Mean± SD, and measurement data with skewed distribu-tion were represented as M(range). Count data were represented as absolute numbers. Results:(1) Surgical situations: 10 patients underwent Da Vinci robotic radical resection of pCCA succe-ssfully, without conversion to laparotomy or intraoperative blood transfusion. The operation time of 10 patients was (465±87)minutes, and the volume of intraoperative blood loss was (167±81)mL. Of the 10 patients, 1 case of Bismuth type Ⅲb had a positive surgical margin and the remaining 9 cases had R 0 resection. (2) Postoperative situations: the time to gastric tube extraction was (2.3±1.9)days, and the duration of postoperative hospital stay of the 10 patients was (19.9±9.0)days. Among the 10 patients, there was no second operation or perioperative death. Of the 10 patients, 6 cases had perioperative complications, including 5 cases wth pleural effusion, 3 cases with peritoneal effusion, and 1 case with intestinal obstruction, some patients had multiple complications. After symptomatic conservative treatment, pleural effusion and peritoneal effusion disappeared and intestinal obstruction was improved. None of the 10 patients had serious complica-tions such as bleeding, biliary fistula or intestinal fistula. (3) Follow-up: 10 patients were followed up for 3-20 months, with a median follow-up time of 11 months. During the follow-up, 3 of 10 patients had tumor recurrence which occurred in intrahepatic bile duct of residual liver, and no implantation metastasis was found in the rest of abdominal cavity. Of the 7 unrecurrent patients, 1 case died of gastrointestinal bleeding and multiple organ failure. Nine of 10 patients survived well. Conclusion:The Da Vinci robotic surgical system used for radical operation of pCCA is feasible.

Portal vein thrombosis is a common complication after esophagogastric devascularization and splenectomy (EDS), with concealment and potential risks, which limited the therapeutic effect. The patients undergoing EDS are often accompanied by severe liver cirrhosis, whose abnormal hemostasis poses a dilemma for antithrombotic therapy. This article reviewed on the research progress of hemostasis of these patients, and risk factors, mechanism, prevention, therapy of post-EDS portal vein thrombosis.

Liver transplantation is an effective curative treatment for hepatocellular carcinoma patients. However, most patients lost the change of surgery when diagnosed as hepatocellular carcinoma. Through local or systemic treatment, hepatocellular carcinoma can be treated in a downstaging manner to reduce tumor burden, so that patients who are beyond the transplantation criteria can still be up to the transplantation criteria after treatment, and finally receive liver transplantation. At present, pre-transplant downstaging treatment has been widely accepted. In this review, we summarized the indications, treatment options, treatment endpoints, and treatment outcomes of pre-transplant downstaging treatment.

Objective@#To investigate the pattern of lymph node metastasis (LNM) in patients with locally advanced (T3, T4) laryngeal squamous cell carcinoma (LALSC) and provide reference for the delineation of clinical target volume.@*Methods@#Clinical data of 272 patients with LALSC treated in our hospital from 2000 to 2017 were retrospectively analyzed. All patients underwent bilateral neck dissection (at least level Ⅱ-Ⅳ). The LNM ratio of each node level was calculated. The risk factors of LNM were identified by univariate and multivariate logistic regression analyses.@*Results@#LNM was found in 156 of 272 patients (57.1%). According to the location of primary lesions, all patients were divided into group A (n=72; unilateral without midline involvement), group B (n=86; unilateral with midline involvement) and group C (n=114; giant or central). In group A, the LNM ratio at ipsilateral level Ⅱ, Ⅲ and Ⅳ was 36.3%, 26.4% and 6.9%, whereas 13.9%, 8.3% and 1.4% at the contralateral level, respectively. In group B, the LNM ratio at ipsilateral level Ⅱ, Ⅲ and IV was 1.9%, 29.1% and 11.6%, whereas 18.6%, 14.0% and 1.2% at the contralateral level, respectively. In group C, the LNM ratio at the left neck level Ⅱ, Ⅲ and Ⅳ was 24.6%, 23.7% and 2.6%, whereas 21.9%, 26.3% and 6.1% at the right neck, respectively. Bilateral LNM ratio did not significantly differ between group A and group B/C (15.3%, 25.0%, P=0.093). Ipsilateral level Ⅲ metastasis (OR=2.929, 95%CI 1.041-8.245, P=0.042) and clinical N stage (OR=0.082, 95%CI 0.018-0.373, P=0.001) were associated with contralateral LNM. Ipsilateral level Ⅱ(P=0.043) or Ⅲ(P=0.009) metastasis were risk factors of the ipsilateral level Ⅳ metastasis.@*Conclusions@#Neck levels Ⅱ and Ⅲ are the high-risk LNM regions, whereaslevels Ⅳ and V are the low-risk areas. Ipsilateral level Ⅱ or Ⅲ metastases are the risk factors of ipsilateral level Ⅳ and contralateral cervical LNM. Contralateral neck LNM rarely occurs in cN0 stage patients.

Objective:To investigate the patterns of regional lymphatic spread and the value of elective neck treatment (ENT) in oral mucosal melanoma (OMM).Methods:In this retrospective analysis, 61 OMM patients with no distant metastasis treated in Cancer Hospital of Chinese Academy of Medical Sciences between 1984 and 2016 were recruitred. The regional lymph node distribution of cN+ disease, the value of ENT in cN 0 disease, the failure patterns and prognostic factors were retrospectively analyzed. Results:Overall, 55.7% of the patients were clinical/pathological cN+ . The most frequently involved locations were the level Ⅰ b (76%), followed by level Ⅱ and level Ⅲ. For cN 0 patients, the 5-year regional failure-free survival rate was 91.7% in patients who received at least ipsilateral level Ⅰ b-Ⅲ ENT and 52.4% in patients who did not receive at least ipsilateral level Ⅰ b-Ⅲ ENT ( P=0.036). The regional failure rate was 6% for patients treated with at least ipsilateral leve Ⅰ b-Ⅲ ENT, while in their counterparts who did not receive at least ipsilateral level Ⅰ b-Ⅲ ENT was 46%( P=0.035). For the regional failure pattern, the most frequently failure sites were level Ⅰ b (93%), level Ⅱ(50%) and level Ⅲ(36%). Conclusions:The cervical lymph node metastasis rate is relatively high in OMM patients. The pathway of regional LN spread follows a regular pattern. The most frequently involved regions for clinical/pathological cN+ and regional failure are both level Ⅰ b-Ⅲ. Elective treatment including at least ipsilateral level Ⅰ b-Ⅲ ENT should be recommended for OMM patients with cN 0.

Objective To evaluate the clinical efficacy,failure pattern and prognostic factors of the malignant mucosal melanoma of the head and neck ( MMHN) in a single center. Methods The treatment pattern,clinical efficacy, failure pattern and prognostic factors of 194 M0MMHN patients admitted to our institution from 1982 to 2017 were retrospectively analyzed.Results The 5-year overall survival (OS),local recurrence-free survival ( LRFS ), regional recurrence-free survival ( RRFS ) and distant metastasis-free survival (DMFS) were 41. 4%,57. 8%,76. 5% and 46. 5%,respectively. The failure rate was calculated as 74. 6%(141/189).Among them,40% (56/141) had distant metastasis as the first pattern of treatment failure,37%(52/141) had local relapse,15%(21/141) had regional relapse,5%(7/141) had concurrent distant metastasis and local/regional relapse and 3% ( 5/141) had concurrent local and regional relapse. Multivariate analysis demonstrated that surgical margins (P=0. 001) and adjuvant radiotherapy (P=0. 000) were the independent prognostic factors for LRFS. Conclusions Surgery combined with radiotherapy can yield relatively high LRFS in the comprehensive treatment of MMHN.Distant metastasis is the major failure pattern.
