ABSTRACT

BACKGROUND@#Chronic obstructive pulmonary disease (COPD) will reduce the cardiopulmonary function and increase perioperative risk. The aim of this study is to investigate the effect of preoperative short-term high intensity lung rehabilitation training on lung function and postoperative complications in patients with COPD who are eligible for lung cancer surgery.@*METHODS@#We analysis of 101 patients with COPD and a diagnosis of lung cancer, with 43 patients in pulmonary rehabilitation group and 58 patients in conventional group. The pulmonary function, postoperative pulmonary complications (PPCs) and length of stay (LOS) will be compared between the two groups, the lung function will be compared before and after the rehabilitation at the same time.@*RESULTS@#There were no significant difference between the two groups in general information, lung function before surgery, postoperative pulmonary infection [8 (18.6%) vs 17 (29.3%)], atelectasis [1 (2.3%) vs 1 (1.7%)], respiratory failure [1 (2.3%) vs 2 (3.4%)] and postoperative LOS [(8.93±3.78) d vs (9.62±3.98) d, P>0.05]. In the rehabilitation group, the FEV1 [(2.06±0.45) L vs (2.15±0.45) L, P<0.001] and PEF [(4.32±0.90) L/s vs (5.15±1.05) L/s, P<0.001) were higher, and PCO2 [(42.42±2.79) mmHg vs (41.58±2.98) mmHg, P=0.009] was lower after rehabilitation, significantly. The increase value of FEV1 in moderate to severe COPD group was higher than that of the mild COPD group after the rehabilitation [(0.16±0.05) L, 8.6% vs (0.06±0.05) L, 2.8%, P<0.001).@*CONCLUSIONS@#The short-term highly-intensity lung rehabilitation can improve lung function in lung cancer patients with COPD, and the improvement of pulmonary function in moderate to severe COPD patients is more obviously.

ABSTRACT

<p><b>BACKGROUND</b>Locally advanced lung cancer includes IIIA and IIIB lung cancer that tumors are localized within the chest and with no clinic and pathologic distal metastasis. In this study the results of extended resection of a portion of heart or great vessels with cardiopulmonary bypass was summarized in the treatment of locally advanced lung cancer.</p><p><b>METHODS</b>Lobectomy or pneumonectomy combined with extended partial excision of the heart or great vessels were carried out in 10 patients with locally advanced lung cancer. The operations included aortic resection and reconstruction with left heart bypass in 2 cases, extended resection of left atrium with normal cardiopulmonary bypass in 5 cases, and resection and reconstruction of superior vena cava in 3 cases respectively.</p><p><b>RESULTS</b>The patients had no operative complication except for one haemothorax, which was controlled by re-exploration. One patient died of brain metastasis 6 months after operation and another one died of multiple metastasis 26 months after operation. The others were alive.</p><p><b>CONCLUSIONS</b>CPB is a safe and effective anesthetic procedure during extended resection of locally advanced lung cancer although it is controversial for aggravating operative trauma, complex technique and higher cost.</p>

ABSTRACT

BACKGROUND: The role of p53 gene in human lung cancer has been confirmed. Since the discovery of p63 gene as the homologue of p53, its role and possible mechanism-have aroused the attention of investigators all over the world. But the principle concerning transcription and expression of p63 in small-cell lung carcinoma (SCLC) remains unclear.OBJECTIVE: To investigate the level of the expression of p63 gene in SCLC and lung adenocarcinoma tumor tissues, peri-carcinoma tissues and normal tissues, and observe the expression of p63 protein in these tissues so as to understand the principle and clinical significance concerning p63gene expression in SCLC and lung adenocarcinoma.DESIGN: Controlled experiment.SETTING: Department of Thoracic and Cardiovascular Surgery, Research Institute of Field Surgery of Daping Hospital of Third Military Medical University of Chinese PLA.PARTICIPANTS: Six SCLC specimens dissected during the surgical operation in Daping Hospital, Third Military Medical Univers ity of Chinese PLA, between October 2000 and September 2002 , were recruited. There were 4 male and 2 female patients aged 42 to 67 years (mean age of 50.7years); 15 specimens of lung adenocarcinoma were also collected at the same time. Tumor tissues, peri-carcinoma tissues and normal tissues were chosen in each specimen.METHODS: Reverse transcriptase polymerase chain reaction (RT-PCR)was used to detect and compare the transcription expression of two subtypes of p63 gene (TAP63 and △NP63)in the tumor tissues of 6 cases of SCLC and 15 cases of lung adenocarcinoma. At the same time, immunohistochemical staining technique was used to detect the expression of p63protein in the above tissues.MAIN OUTCOME MEASURES: ① Expression of p63 protein detected by RT-PCR in tissue specimens. ② Expression of p63 protein detected in tissue specimens detected by immunohistochemical staining technique.RESULTS: ① Expression of p63 protein detected by RT-PCR in tissue specimens: The positive expression of △Np63 gene could be found in 5cases (83%, 5/6) of SCLC cancer tissues and 1 case of SCLC peri-carcinoma tissues (17%, 1/6), and the expression of TAp63 was not observed in all of the tumor, peri-carcinoma and normal tissues of SCLC. There was no expression of △Np63 or TAp63 in tumor, peri-carcinoma and normal tissues of lung adenocarcinoma. ② Expression of p63 protein detected by immunohistochemical staining in tissue specimens: The positive expression rate of p63 protein in SCLC tumor tissues was significantly higher than that in lung adenocarcinoma tissues [83% (5/6), 17% (1/6), P < 0.01].CONCLUSION: p63 gene shows positive expression in SCLC, among which the expression level of △NP63 is increased while the expression level of p63 protein is obviously higher in SCLC than in adenocarcinoma tissues, which may be related to its regulatory role in the occurrence and development of SCLC. It is presumed that△NP63 gene has high transcription expression level in SCLC, which might inhibit cellular apoptosis, promote the proliferation of tumors, play the role as an oncogene. It suggests that p63 may be one of the factors influencing the prognosis of SCLC.

ABSTRACT

<p><b>BACKGROUND</b>To investigate the expression of p63 gene and its significance in non-small cell lung cancer (NSCLC) and pulmonary benign disease tissues.</p><p><b>METHODS</b>p63 gene mRNA expression (TAp63 and ΔNp63) was detected in 40 NSCLC and 10 pulmonary benign disease tissues by RT-PCR (reverse transcriptase-PCR) technique, and immunohistochemical method was used to observe p63 protein expression in the above tissues.</p><p><b>RESULTS</b>ΔNp63 mRNA overexpression was observed in 18 squamous cell carcinoma (18/23), 1 bronchioloalveolar carcinoma (1/6) and 2 paracancerous tissues of squamous cell carcinoma (2/23). There was no expression of TAp63 both in NSCLC and benign disease tissues of the lung. Immunochemistry showed that the positive rate and intensity of p63 protein expression were significantly higher in squamous cell carcinoma than those in adenocarcinoma and benign disease tissues of the lung ( P < 0.01).</p><p><b>CONCLUSIONS</b>p63 gene is mainly amplified in squamous cell carcinoma of the lung. It may act as an oncogene in the carcinogenesis and development of squamous cell carcinoma.</p>

ABSTRACT

<p><b>BACKGROUND</b>To explore the sequential variation of pulmonary flow spectrum and its value on evaluation of risk for pulmonary resection in perioperative patients with lung cancer.</p><p><b>METHODS</b>Forty-nine patients with lung cancer who underwent pneumonectomy (12 cases) and lobectomy (37 cases) were observed for the values of Doppler pulmonary flow spectrum before operation, on the 3-5 days and 8-10 days postoperatively. Moreover the patients were divided into different groups according to the different operative procedures and with or without postoperative cardiac arrhythmia.</p><p><b>RESULTS</b>Doppler pulmonary flow spectrum changed in all cases who underwent pneumonectomy and lobectomy from 3 to 5 days postoperatively. These changs included prolonged preejection period (PEP), shortened acceleration time (ACT), increased PEP/ACT ratio, increased pulmonary artery mean pressure (PAMP), and increased pulmonary vascular resistance (PVR). There were significant differences comparing with those before operation ( P < 0.01). The patients who underwent lobectomy recovered to the same level of pre operation on the 8th to 10th postoperative days. However, the changes of pulmonary flow spectrum continuously existed in the patients who underwent pneumonectomy on the 8th to 10th postoperative days. There were significant differences of pulmonary flow spectrum between patients with postoperative arrhythmia and without postoperative arrhythmia before operation.</p><p><b>CONCLUSIONS</b>Pulmonary hemodynamic obviously changes after pulmonary resection in the patients with lung cancer and the changes last longer in pneumonectomy patients. Patients with postoperative cardiac arrhythmia have marked pulmonary hemodynamic changes before operation. Doppler pulmonary flow spectrum can not only be used to analyse the pulmonary hemodynamic changes for those cases undergoing pulmonary resection after operation, but also to evaluate the risk of pulmonary resection before operation.</p>
