Objective To explore the histopathological features of 850 patients with esophageal malignant tumor in 10 years.Methods From January 2002 to January 2012, 850 patients diagnosed with esophageal malignant tumor were enrolled.Tumor location, general type, pathological type and TNM stage were retrospectively analyzed.All the data were described as case number and percentage.Results Among the 850 cases of esophageal malignant tumor, 33 lesions (3.9％) located in the neck segment of esophagus, 119 lesions (14.0％) located in the upper segment, 44 lesions (5.2 ％) located in the upper-middle segment, 409 lesions (48.1％) located in the middle segment, 123 lesions (14.5 ％) located in the middle-lower segment, 122 lesions (14.4％) located in the lower segment.Among the 724 eases clearly diagnosed as esophageal malignant tumor by general type, the most cases were ulcer type (305 cases, 42.1％), followed by medulla type (260 cases, 35.9％), fungating type (80 cases, 11.0％) and constrictive type (70 cases, 9.7％), and the least cases were intraluminal type (nine cases, 1.2％).Among the 850 cases of esophageal malignant tumor, squamous cell carcinoma (794 cases, 93.4 ％) was the most common cytological type, followed by small cell carcinoma (19 eases, 2.2％), and the least common cytological type was adenocarcinoma (seven cases, 0.8 ％).Among the 724 cases with clear TNM staging, case number of Tis, T1, T2, T3 and T4 stage was eight (1.1％), six (0.8％), 271 (37.4％), 278 (38.4％) and 161 (22.2％), respectively.Among the 122 cases of distal esophageal carcinomas (104 cases with clear TNM staging), most cases were squamous cell carcinoma (112 cases, 91.8 ％), the others cases were adenocarcinoma (three cases, 2.5 ％), small cell carcinoma (three cases, 2.5 ％), basaloid squamous cell, adenosquamous, neuroendocrine carcinomas and carcinosarcoma (one case in each type, 0.8％).Conclusions Esophageal carcinoma was mostly located in the middle segment of in which squamous cell carcinoma was predominant while adenocarcinoma was less common.Esophageal cancer located at lower segment of esophagus is with a wide range of pathological spectrum, squamous cell carcinoma was still dominant, however, esophageal adenocarcinoma is rare.

Objective To explore the relation between clinical-pathological features,Siewert classification and prognosis of esophagogastric junction (EGJ) carcinoma,and to assess the applicability of the new edition of American Joint Committee of Cancer (AJCC) staging guideline on EGJ adenocarcinoma in China.Methods From 2002 to 2012,the clinical data,pathological features,treatment and prognosis of 218 patients with EGJ malignant tumor were retrospectively analyzed.The patients were typed according to Siewert classification criteria and each case was staged according to 7th edition of AJCC TNM staging criteria for esophagus adenocarcinoma and gastric cancer.Kaplan-Meier method and Log-rank test were performed for survival analysis.Results According to the Siewert classification,type Ⅰ was rare (nine cases,4.1％),type Ⅱ was the most common type (150 cases,68.8％) and followed by type Ⅲ (59 cases,27.1％).There was no significant difference in survival curve among the three types (P＞0.05).The survival curve was drawn according to 7th edition of AJCC TNM staging criteria for esophagus adenocarcinoma.In T staging,the prognosis of patients at T4b was better than that of patients at T4a,the prognosis of patients at ⅡB was better than that of patients at ⅡA.The survival curve of patients at Ⅲ C obviously crossed with that of patients at Ⅳ,which was not in conformity with clinical results.The survival curve was drawn according to 7th edition of AJCC staging criteria for gastric cancer.In T staging,the survival curve of patients at Tis was overlapped with that of patients at T1a.The survival rate of patients at ⅡB could not be accurately predicted by the overall staging.In general,the survival of patients with EGJ carcinoma was better predicted according to 7th edition of AJCC staging criteria for gastric cancer than 7th edition for esophagus adenocarcinoma.Conclusions Neither 7th edition of AJCC staging criteria for esophagus adenocarcinoma nor for gastric cancer could accurately predict its prognosis.In our country,EGJ malignant tumor was similar to gastric cancer and had specific clinical-pathological features.It is necessary to research and establish EGJ carcinoma staging criteria instead of applying the current staging criteria for esophagus adenocarcinoma or gastric cancer.

Objective To study effects and other related problems of surgery for patients with cervical spine fracture and ankylosing spondylitis.Methods Twelve patients with cervical spine fracture and ankylosing spondylitis were treated with surgery from April 1986 to April 2004.All eases were studied retrospectively.They were followed up for an average of 67.5 months and their complete clinical data were kept.The neurological function was evaluated by ASIA (American Spinal Injury Association) impairment scale,and the image analyzing software (Image-Pro Plus 5.1) was used to measure the angles of superior and inferior vertebral bodies of the fusion segment at flexion and extension positions.The difference between flexion and extension angles,?,served as the parameter of interspinal movement.According to the definition of spinal fusion by FDA (Food and Drug Administration),the?≥4?was considered as nonfusion.Other related problems were discussed by descriptive study.Results The average improvement in the nine patients with neurological injury was 1.3 ASIA grades.The injured segments in 10 cases were treated with fusion,of whom nine were fused by internal fixation.The fusion rate was 100%.Three cases were scheduled to have laminoplasty,but two had to receive laminectomy instead because of intraoperative complete fracture at the hinged side.Ten patients were complicated by insufficient function of major organs preop- eratively,and endotracheal intubation was difficult to perform in eight cases.Postoperative complications occurred in three cases,but fortunately healed completely.There were no deaths or fatal complications.Conclusions The neurological function can be improved by surgery for patients with cervical spine fracture and ankylosing spondylitis. Although the cervical spine is instable for most of the patients,fusion with internal fixation is indicated and can be successful.Those who had preoperative systemic diseases are likely to suffer from postoperative complications.The difficult endotracheal intubation is a common intraoperative problem.
