Objective To investigate the status quo and influencing factors of depression and anxiety in postoperative patients with thoracic neoplasms. Methods The general information questionnaire and Huaxi emotional-distress index scale (HEI) were adopted to survey 70 patients after surgery of thoracic neoplasms at the thoracic nursing outpatients from September to November 2016. There were 43 males and 27 females with age of 18-78 (56.20±11.34) years. Results The prevalence rate of depression and anxiety among postoperative patients with thoracic neoplasms was 50.0%, and moderate to severe negative emotions predominated. There was significant difference in educational levels, postoperative hospitalization and postoperative complications (P<0.05), while no significant difference in age, gender, disease types, complicated diseases, surgical procedures, pathological stages and hospitalization expenditures between patients with unhealthy emotions and normal emotions (P>0.05). Conclusion There is a high prevalence rate of negative emotion among postoperative patients with thoracic neoplasms. Educational levels, postoperative hospitalization and postoperative complications are important factors for negative emotion.
Pulmonary adenocarcinoma in situ is reclassified as precursor glandular lesions in the fifth edition of WHO classification of thoracic tumours, causing widespread attention and heated debate among domestic thoracic oncologists, radiologists, pathologists and surgeons. We would like to comment on the topic and make a few suggestions on the management of pulmonary nodule during lung cancer screening. We are open to all suggestion and welcome debates.
Mediastinal and chest wall tumors contain various benign and malignant tumors. In order to further standardize the whole-course diagnosis and treatment of mediastinal and chest wall tumors, the consensus was formulated through discussion by the expert group. Based on the clinical diagnosis and treatment experience and various prospective and retrospective studies, the consensus was formed.
Objective To establish a patient-derived tumor xenograft (PDTX) model and to observe the latency and rate of tumor formation, tumor size, tumor invasion and metastasis of transplanted tumors. Methods Seven patients with chest tumor in Drum Tower Hospital from April to December 2015 were chosen. There were 5 males and 2 females with age ranging from 61-71 years, including 4 patients of esophageal tumor and 3 patients of lung tumor. PDTX model was established by surgical removal of fresh tumor tissues of these patients and transplantation in NOD-Prkdcem26Il2rgem26Nju subcutaneous (NCG) mice. The latency and rate of tumor formation, tumor size, tumor invasion and metastasis of transplanted tumors were observed, and pathology of HE staining and immunohistochemical testing results were compared between PDTX model and the patients. Results PDTX model was successfully established in 4 patients, and the success rate was 66.7%, including 2 patients of esophageal cancer. The PDTX model retained the differentiation, morphological and structural characteristics of original tumors. Conclusion Pathology and molecular biology characteristics of PDTX model are consistent with the original tumor, which can be an " avatar” of tumor patients for clinical pharmacodynamics screening and new drug research and development.
Objective To understand the status quo of depression and anxiety emotion in perioperative patients with thoracic neoplasms under the concept of enhanced recovery aftersurgery. Methods Huaxi emotional-distress index scale (HEI) was adopted to investigate the mental status of 195 patients with thoracic neoplasms in Department of Thoracic Surgery, West China Hospital, and the nursing outpatients between September and November in 2016. There were 118 males and 77 females at age of 17–80 (55.72±12.66) years. Results There was significant difference in mental health level between the preoperative patients and the postoperative patients (3.70±3.41vs. 11.01±9.78,P<0.001). The incidence of depression and anxiety emotion in the postoperative patients was significantly higher than that in the preoperative patients (50.00%vs. 9.60%, P<0.001). Besides, there was significant difference of depression and anxiety degree between the preoperative patients and postoperative patients (P<0.001). Moderate to severe depression and anxiety were mostly found in the postoperative patients while mild to moderate depression and anxiety in the preoperative patients. Conclusion Patients with thoracic neoplasms have much emotional obstacle in perioperative period. The incidence and severity degree of depression and anxiety emotion in postoperative patients are higher than those in preoperative patients.
ObjectiveTo explore the clinical characteristics, diagnosis and treatment of thoracic inflammatory myofibroblastic tumor.MethodsThe clinical data, pathological features, treatment and prognosis from 10 patients with thoracic inflammatory myofibroblastic tumor confirmed by pathology were analysed retrospectively from April 2012 to April 2019 at Jiangsu Province Hospital (The First Affiliated Hospital of Nanjing Medical University).ResultsTen participants including six males and four females with a mean age of 37.9 years old. Lesions were detected by physical examination in five patients, cough, chest pain and hemoptysis were the common symptoms. A total of 10 lesions including six in the right lung, three in the left lung and one in the mediastinum. Nine patients were treated with surgery, and one patient received high-frequency electrocautery though rigid bronchoscopy under general anesthesia. All the patients were confirmed by immunohistochemistry, positive rate of smooth muscle actin was 70%, positive rate of anaplastic lymphoma kinase was 70%. The mean follow-up time was 35.9 months, and one patient relapsed the other nine patients were cured.ConclusionsInflammatory myofibroblastic tumor is potentially malignant or low malignant, the clinical manifestations and imaging findings are not specific, once confirmed by pathology, radical surgery is the first choice. For the lesion limited to the airway, interventional therapy could be the choice, but close follow up is needed.
Abstract： Objective To investigate the effect of preoperative oral carbohydrate （CHO） administration on perioperative risks of patients with surgical thoracic oncology，and provide evidence for establishing new scientific preoperative fasting strategy.Methods?In this prospective study， from July to September 2010，32 out of 65 enrolled patients with surgical thoracic oncology in Department 1 of Thoracic Surgery，Cancer Hospital of Peking University， were randomly allocated to preoperative experiment group （fasting overnight and oral 12.5% dextrose 400 ml administration 2 h before anesthesia induction） or control group （fasting overnight and water deprivation from midnight）. Clinical data were collected including subjective evaluation of thirst and hunger measured by visual analogue scale （VAS）， blood glucose level（BGL），serum insulin level， homeostasis model assessment insulin resistance（HOMA-IR），postoperative length of hospital stay （LOS） and complications.Results?Sixteen patients were enrolled in each group. VAS scores of thirst and hunger of the preoperative experiment group at 1 h before anesthesia induction were significantly lower than those of the control group（24 vs. 49，24 vs. 62 ，P=0.000）. BGL（8.59±0.43 mmol/L vs. 5.59±0.43 mmol/L， P=0.000）， serum insulin level （24.33±1.80 mIU/ ml vs. 16.28±1.80 mIU/ml， P=0.004）and HOMA-IR（9.23±0.77 vs. 4.03±0.77，P=0.000）of the preoperative experiment group before anesthesia induction were significantly higher than those of the control group，and these three variables of the preoperative experiment group returned to baseline level soon after surgery. There was no statistical difference in postoperative LOS and complication rate between the two groups （P＞0.05）.Conclusion?Preoperative oral CHO treatment is safe for non-diabetic patients with surgical thoracic oncology， can alleviate their subjective discomfort，decrease insulin resistance， and ameliorate their perioperative stress and metabolism.
