Objectives To analyze the risk factors of secondary infections in breast cancer or lung cancer patients with chemotherapy-induced degree Ⅳ neutropenia, so as to provide reference for clinical treatment. Methods The case-control study design was used. Thirty-seven in-patients of breast cancer or lung cancer with secondary infections and 87 in-patients without secondary infection in the First Affiliated Hospital of Xi’an Jiaotong University from January to December 2014 were enrolled as study population. We collected the retrospective information and analyzed the risk factors of secondary infection with chemotherapy-induced degree Ⅳ neutropenia using factors under univariate analysis and logistic regression analysis. Results Single factor analysis showed that the patients whose MASCC<21 the had higher infection risks (P<0.05). For breast cancer patients with degree Ⅳ neutropenia, secondary infection risk of first two chemotherapy cycles was 2.87 times of subsequent cycles of chemotherapy. For lung cancer patients with degree Ⅳ neutropenia, invasive procedures and preventive use of antibiotics increased risk of infection (P<0.05). Logistic regression analysis showed MASCC score and chemotherapy cycles were significantly associated with secondary infection in breast cancer degree Ⅳ neutropenia patients (P<0.05). Invasive procedures were significantly correlated to secondary infection of patients with lung cancer degree Ⅳ neutropenia (P<0.05). Conclusions MASCC score and chemotherapy cycles are the risk factors of infection in breast cancer patients with degree Ⅳ neutropenia, and invasive procedures are the independent risk factors of infection in lung cancer patients with degree Ⅳ neutropenia.
Lung cancer ranks among the most prevalent and lethal malignancies globally. Its prognostic outcomes are not only contingent upon tumor characteristics and therapeutic interventions but also intricately linked to the nutritional and immune profiles of patients. This article conducts a thorough review of both domestic and international research, providing a comprehensive synthesis of the prognostic value of widely investigated nutritional and immune indicators in the context of lung cancer. The primary objective is to identify optimal prognostic markers in clinical practice, offering guidance for precise post-treatment assessment and early intervention for lung cancer patients.
ObjectiveTo investigate the feasibility and safety of single utility port Da Vinci robot-assisted lung resection via anterior approach.MethodsThe clinical data of 21 patients who underwent single utility port Da Vinci robot-assisted lung resection from February to March 2021 were retrospectively analyzed. There were 10 males and 11 females, with a median age of 50 (34-66) years. The operation time, blood loss, postoperative hospitalization time, postoperative complications and other indicators were analyzed.ResultsAll patients completed the operation successfully with no transition to thoracotomy or perioperative death. Overall surgery time was 103 (70-200) min, Docking time was 5 (3-10) min, operation time was 81 (65-190) min. The blood loss was 45 (20-300) mL. All patients had malignant tumors, the number of dissected lymph node station was 3 (1-6), and the number of lymph nodes was 5 (2-16). The postoperative indwelling time was 3 (2-5) d. The postoperative hospitalization time was 5 (3-7) d. The pain score for the first 3 days after surgery was 3±1 points.ConclusionSingle utility port robot-assisted lung resection via anterior approach is safe, less traumatic, more convenient and effective, which can be gradually promoted and applied to clinical trials.
Objective To review the current state of lung rehabilitation in China and explore the effect of lung rehabilitation on chronic respiratory diseases. Methods Database of CNKI ( 1979-2009) , VIP Chinese Periodical Database ( 1989-2009 ) , and Wanfang Data ( 1982-2009) resources were searched. Studies of lung rehabilitation were collected, and randomized and controlled trials were included. Data were extracted on study population, interfering and evaluating methods. The meta-analyses were performed by using RevMan 4. 2 software. The heterogeneity was analyzed by X2 and P value. Results A total of 3 clinical trials met the inclusion criteria. The study population were all severe and very severe chronic obstructive pulmonary diseases ( COPD) patients. Lung rehabilitation could improve daily activity( WMD:1. 29, 95% CI: 1. 05-1. 54) and dyspnea level ( SMD: - 1. 27, 95% CI: - 1. 67 to - 0. 86) of COPD patients. Conclusion The general level of studies on lung rehabilitation is not satisfied. Meta-analysis comfirmes that lung rehabilitation is beneficial in improving daily activity and dyspnea level of COPD patients.
Lung volume reduction surgery （LVRS） has been applied generally since it was redeveloped and lucubrated. A recent large, multicenter trial showed LVRS can improve lung function, exercise capacity, quality of life, and even survival in certain highly selected patients. LVRS has been developed as an effective therapy for severe emphysema, which offers a new approach for the victims of emphysema. The development of operative technique and clinical effect about LVRS are reviewed in this article.
Abstract： Objective To introduce the new procedure of endobronchial ultrasoundguided transbronchial needle aspiration (EBUSTBNA) for staging lung cancer and diagnosing thoracic diseases, in order to determine its value in the evaluation of thoracic diseases. Methods We retrospectively reviewed the data of all patients examined with EBUSTBNA our institution between September 2009 and May 2010. Among the patients, there were 75 males and 31 females with an average age of 62.3 years old. Based on their primary indication, we divided all the 106 patients into three categories. (1) There were 76 patients with known or bly suspected lung cancer. Enlarged mediastinal lymph nodes on radiographic examination of the chest (≥1.0 cm) were detected in all the patients. (2) There were 22 patients with enlarged mediastinal lymph nodes or mediastinal masses of unknown origin. (3) There were 8 patients with pulmonary mass located close to the central airways. Results (1) 76 patients underwent EBUSTBNA for known or bly suspected lung cancer. Among them, 58 patients were confirmed to have mediastinal lymph nodes metastasis on EBUSTBNA. Sixteen in the 18 patients with negative EBUSTBNA underwent thoracoscopy or thoracotomy for pulmonary resection and mediastinal lymph node dissection. Postoperative pathology confirmed that 12 patients did not have metastatic nodes, 2 patients had metastatic nodes and 2 other patients had benign lesions within the lung. The diagnostic sensitivity, specificity and accuracy of EBUSTBNA for the mediastinal staging of lung cancer were 96.66%(58/60), 100.00%(12/12) and 97.22%(70/72), respectively. (2) 22 patients underwent EBUSTBNA for the evaluation of mediastinal adenopathy or mass in the absence of any identifiable pulmonary lesion. Among them, 7 had malignancy, 13 had benign diseases on EBUSTBNA and the sensitivity of EBUSTBNA in distinguishing malignant mediastinal diseases was 87.50% (7/8). (3) 8 patients with pulmonary mass located close to the central airways were accessed by EBUSTBNA. Definite diagnosis was achieved in 7 patients, and lung cancer was detected in 6 patients. The sensitivity and the diagnostic accuracy of EBUSTBNA for the diagnosis of unknown pulmonary mass was 85.71%(6/7) and 87.50%(7/8), respectively. All the procedures were uneventful, and there were no complications. Conclusion EBUSTBNA is a highly effective and safe procedure. We believe that EBUSTBNA should be used routinely in the diagnosis and staging of thoracic diseases.
Objective To improve accuracy of clinical diagnosis through analyzing the CT characteristics and clinical manifestations of patients with benign lung diseases whose CT manifestations initially led to a suspicion of lung cancer. Methods This study collected 2 239 patients of benign lung disease verified by postoperative pathology in the Department of Thoracic Surgery, Beijing Chao-yang Hospital from June 2006 to December 2016. Lesions of 173 patients (101 males and 72 females with a mean age of 56.0 years) were considered very likely to be malignant on preoperative contrast CT scan, which were sorted to 20 types of lung diseases, and the 20 types of diseases contained 907 patients diagnosed or misdiagnosed. Statistical analyses were performed using the CT and clinical characteristics of the 173 patients. Results Among the 907 patients with benign lung disease, the benign pathologies that were most commonly misdiagnosed by preoperative enhanced CT were pulmonary leiomyoma (100.0%), pulmonary actinomycosis (75.0%), pulmonary cryptococcosis (71.4%), sclerosing hemangioma (50.0%) and organizing pneumonia (44.2%). Among the 173 patients with benign diseases, the most common diseases were tuberculosis (29.5%), organizing pneumonia (28.9%), pulmonary hamartoma (6.4%) and pulmonary abscess (6.4%). In the 173 patients, 17.3% had fever, 56.6% coughing, 8.7% yellow sputum, 28.9% hemoptysis, 16.2% chest pain, 18.5% elevated leukocyte counts and 4.6% elevated carcinoembryonic antigen levels. Most of the CT manifestations consisted of nodular or mass shadows, 70.5% of which had foci≤3 cm and manifestations were similar to those of lung cancer, such as a spiculated margin (49.1%), lobulation (33.5%), pleural indentation (27.2%) and significant enhancement (39.3%). Furthermore, some patients had uncommon tumor signs, such as calcification (12.7%), central liquefactive necrosis (18.5%), satellite foci (9.8%) and multiple pulmonary nodules (42.2%). Moreover, 24.3% of the patients had enlarged lymph nodes of the mediastinum or hilum. Conclusion As the CT manifestations of some benign lung conditions are similar to those of lung cancer, careful differential diagnosis is necessary to identify the basic characteristics of the disease when the imaging results are ambiguous, and the diagnosis of a lung disease need incorporate the patients' clinical characteristics and a comprehensive analysis.
With the development and improved availability of low-dose computed tomography (LDCT), an increasing number of patients are clinically diagnosed with lung cancer manifesting as ground-glass nodules. Although radical surgery is currently the mainstay of treatment for patients with early-stage lung cancer, traditional anatomic lobectomy and mediastinal lymph node dissection (MLND) are not ideal for every patient. Clinically, it is critical to adopt an appropriate approach to pulmonary lobectomy, determine whether it is necessary to perform MLND, establish standard criteria to define the scope of lymph node dissection, and optimize the decision-making process. Thereby avoiding over- and under-treatment of lung cancer with surgical intervention and achieving optimal results from clinical diagnosis and treatment are important issues before us.
Objective To evaluate the diagnostic value and utility of flexible bronchoscopy in the preoperative assessment in patients with solitary pulmonary nodules (SPNs). Methods A total of 111 patients with SPNs of unknown origin treated between January and June 2016 were retrospectively enrolled. The clinical characteristics, bronchoscopy findings and surgical strategies were collected. Results In the total 111 cases, malignant and benign SPNs were 79 and 32 cases, respectively. The mean diameter of malignant SPNs was larger than that of benign SPNs [(2.04±0.58) vs. (1.70±0.75) cm, P<0.05]. Bronchoscopy identified 9 cases (8.1%) unsuspected findings. Surgeries were modified or cancelled in 3 patients (2.7%) because of bronchoscopy findings. Transbronchoscopy biopsies were performed in 26 patients, 9 of whom were diagnosed lung cancer preoperatively, with a sensitivity of 45% (9/20) and a specificity of 100% (6/6). Conclusions Flexible bronchoscopy can be contributed to diagnosis of SPN before surgery and determination of surgical strategies. It is suggested that flexible bronchoscopy could be included in the routine preoperative work-up of SPN.
Abstract： Objective To investigate strategies for prevention，early diagnosis，and prompt treatment for acute pulmonary embolism（PE）after video-assisted thoracoscopic surgery（VATS）lobectomy. Methods From January 2007 to November 2010, 1 115 patients with lung cancer underwent VATS lobectomy in the First Affiliated Hospital of Guangzhou Medical College. Among them, 13 patients had acute PE postoperatively, including 6 male patients and 7 female patients with their mean age of 62.3 years（ranging from 42 to 73 years）.All the patients were diagnosed by spiral CT pulmonary artery angiography（SCTPA）, and received anticoagulation therapy with low molecular weight heparin and warfarin. Results The incidence of acute PE after VATS lobectomy was 1.17%（13/1 115）, and the patients with low PE-related early mortality risk accounted for a large proportion（11/13）. There were 12 patients with right-side PE. All the patients’ signs and symptoms were significantly alleviated after administration of anticoagulation therapy. Nine patients received SCTPA review after treatment which showed that their PE had disappeared or been significantly absorbed. No hematological complications including thoracic hemorrhage or wound errhysis occurred after treatment. All surviving patients were followed up for 1 month to 3 months. During follow-up, these patients were alive without PE recurrence. Conclusion SCTPA is the first-choice examination for the diagnosis of acute PE after VATS lobectomy. Prophylaxis against PE and prompt treatment are necessary depending on individual manifestations. VATS lobectomy should be favored as a minimally invasive surgical treatment for patients with lung cancer, for the low incidence of postoperative PE and low PE-related early mortality risk.
