RESUMO
OBJECTIVE: To explore the surgical treatment and prognostic factors of bronchopulmonary carcinoid tumors (BPC). METHODS: The clinical data of 65 patients undergoing surgery for BPC from May 1999 to December 2007 were reviewed retrospectively. The predictors of univariate and multivariate analyses included gender, age, smoking history, pathological type and tumor stage. RESULTS: The procedures included segmentectomy (n = 1), lobectomy (n = 36), bilobectomy (n = 6), sleeve resection (n = 4), pneumonectomy (n = 11), carinal resection (n = 2), bronchoplastic resection (n = 4) and exploratory thoracotomy (n = 1). The 1- , 3- and 5-year overall survival rates were 86.2%, 73.8% and 64.6% respectively. Univariate analysis showed that gender (P = 0.029), age (P = 0.003), smoking history (P = 0.039), pathological type (P < 0.01), tumor stage (P < 0.01), postoperative radiochemotherapy (P < 0.01), lymph node metastasis (P < 0.01) and surgical type (P = 0.042) were prognostic factors. And multivariate analysis revealed that pathological type (P = 0.019) and lymph node metastasis (P < 0.01) were independent prognostic factors. CONCLUSION: Surgery remains a first-choice for BPC. The major resection procedure is anatomical lobectomy or pneumonectomy. Both pathological type and lymph node metastasis are independent prognostic factors.

OBJECTIVE: To compare the instructive value of the 6th and 7th editions of the UICC-AJCC staging system in prognosis of esophageal cancer (EC) patients. METHODS: The staging and prognosis of 1397 esophageal carcinoma patients undergoing curative resection from Jan. 2003 to Dec. 2006 in our hospital were retrospectively reviewed and analyzed according to the 6th AJCC staging system and the 7th UICC-AJCC staging system. RESULTS: The 5-year overall survival (OS) of EC patients with curative resection was 38.5% (481/1250 cases), with a follow-up rate of 89.5% (1250/1397 case). In overall terms, both the editions were statistically significant discriminators of OS (P < 0.05). The 5-year OS of stages I, II and III patients were 64.9%, 43.5%, 25.2% according to the 6th edition, and 63.5%, 44.5%, 23.5% according to the 7th edition, respectively. Distinct differences in survival were present among patients categorized as stage Ia and Ib according to the 7th edition (P < 0.05), with a 5-year OS of 80.0% and 58.3%, respectively. Similarly, according to the 7th edition, the 5-year overall survivals (OS) of the stages IIIa, IIIb and IIIc patients were 28.2%, 18.4% and 16.7%, respectively, showing that the prognoses were significantly different (P < 0.05). In addition, according to the 7th edition, the prognoses of patients in stages N0, N1, N2 and N3 were also significantly different (P < 0.01), and the 5-year OS were 50.0%, 31.5%, 18.7% and 16.7%, respectively. CONCLUSIONS: Both the 6th and 7th editions of UICC-AJCC staging system are significant discriminators for survival of esophageal cancer patients. The 7th edition is proved to be more accurate in prognosis. The number of lymph node metastases is an important predictor of prognosis.

OBJECTIVE: To evaluate and compare the value of cardiopulmonary exercise test and conventional pulmonary function tests in the prediction of postoperative cardiopulmonary complications in high risk patients with chest malignant tumors. METHODS: From January 2006 to January 2009, 216 consecutive patients with thoracic malignant tumors underwent conventional pulmonary function tests (PFT, spirometry + DLCOsb for diffusion capacity) and cardiopulmonary exercise test (CPET) preoperatively. The correlation of postoperative cardiopulmonary complications with the parameters of PFT and CPET were retrospectively analyzed using Chi-square test, independent sample t-test and logistic regression analysis. The P value < 0.05 was considered as statistically significant. RESULTS: Of the 216 patients, 57 did not receive operation due to advanced stage diseases or poor cardiopulmonary function in most of them. The remaining 159 underwent different modes of operations. Thirty-six patients (22.6%) in this operated group had postoperative cardiopulmonary complications and 10 patients (6.3%) developed operation-related complications. Three patients (1.9%) died of the complications within 30 days postoperatively. The patients were stratified into groups based on V(O(2)) max/pred (≥ 65.0%, < 65.0%); V(O(2)) max×kg(-1)×min(-1) (≥ 20 ml, 15 - 19.9 ml, < 15 ml) and FEV1 (≥ 2.0 L, 1.2 - 1.99 L, < 1.2 L) according to the criteria in reported papers. There was statistically significant difference among these groups in the parameters (P < 0.05), the rates of postoperative cardiopulmonary complications were much higher in the groups with poor cardiopulmonary function (V(O(2)) max/pred < 65.0%; V(O(2)) max×kg(-1)×min(-1) < 15 ml or FEV1 < 1.2 L). It was shown by logistic regression analysis that postoperative cardiopulmonary complications were significantly correlated with age, associated diseases, poor results of PFT or CPET, operation modes and operation-related complications. CONCLUSIONS: FEV1 in spirometry, V(O(2)) max×kg(-1)×min(-1) and V(O(2)) max/pred in cardiopulmonary exercise test can be used to stratify the patients' cardiopulmonary function status and is correlated well with FEV1. V(O(2)) max×kg(-1)×min(-1) is the best parameter among these three parameters to predict the risk of postoperative cardiopulmonary complications in patients with chest malignant tumors and borderline cardiopulmonary function.

OBJECTIVE: Up to now surgical treatment has been still the most effective treatment for esophageal cancer. However, postoperative lymph node recurrence is still a frequent event and affects long term survival considerably. The aim of this study is to compare the results of lymph node dissection via left vs. right thoracotomies and to verify whether there is any essential difference in lymphadenectomy between these two approaches. METHODS: Five hundred and fifty-nine cases with thoracic esophageal cancer were randomly selected from the database of esophageal cancer patients who underwent surgical treatment in our hospital between May 2005 and January 2011, including 282 cases through left thoracotomy and 277 cases through right thoracotomy. This series consisted of 449 males and 110 females with a mean age of 58.8 years (age range: 36 - 78 years). The pathological types were mainly squamous cell carcinoma (548 cases) and other rare types (11 cases). The data were analyzed and compared using Chi-square test. The P-value < 0.05 was considered as statistically significant. The actual 5-year survival rate was calculated based on the recent follow-up data of the patients who underwent surgery at least 5 years ago. RESULTS: The average number of dissected lymph nodes was 23.4 via left versus 24.6 via right thoracotomies. The overall lymph node metastasis rate was 48.9% via left thoracotomy and 53.8% via right thoracotomy, and 34.8% vs. 50.5% in the chest (P < 0.001), 29.1% vs. 17.7% in the abdomen (P = 0.001). The pathologically confirmed lymph node metastasis rate was 45.9%, 44.0% and 34.9% in the upper, middle and lower segments of thoracic esophagus, respectively. The lymph node metastasis rates detected via left and right thoracotomy in the stage T1 cases were 14.7% (5/34) vs. 42.9% (12/28) (P < 0.001), and in the stage T2 cases were 35.4% (17/48) vs. 52.8% (28/53) (P = 0.007); in the station of para-thoracic esophagus were 9.6% vs. 13.4%, in the left upper mediastinum were 2.1% vs. 7.6%, and in the right upper mediastinum were 1.4% vs. 26.0%, respectively. The preliminary actual 5-year survival rate was 38.2% in the cases via left thoracotomy vs. 42.1% in those via right thoracotomy. CONCLUSIONS: The results of this study demonstrate that lymph node dissection is more complete via right thoracotomy than via left thoracotomy, especially for the tracheoesophageal groove and para-recurrent laryngeal nerve nodes, which may eventually improve the survival of patients with esophageal cancer. Therefore, surgical treatment via right thoracotomy by Ivor-Lewis (two incisions) mode or Levis-Tanner (three incisions) mode with two-field or three-field complete lymph node dissection may become prevalent in the future.

OBJECTIVE: To investigate the efficacy of surgical treatment of sternal tumors and repairing methods of the chest wall defects. METHODS: Fifteen patients with sternal tumors were diagnosed and underwent resection of the sternal tumors according to the en-bolck principle and repair of the chest wall defects using various materials from January 1968 to December 2010 in our hospital. RESULTS: Of 6 patients with sternal manubrim tumors, one patient had reconstruction only with steel wire, other 5 patients healed completely after repair with soft materials. Of 7 patients with sternal body tumors, one patient recovered quickly without reconstruction because he had only partial resection; four patients had chest wall repair with soft materials, but they breathed hardly; and two patients had chest wall reconstruction with rigid materials. One patient had ventilatory support, another patient recovered quickly. Ventilatory support was needed in two patients treated by subtotal sternectomy because they had chest wall repair with soft materials. CONCLUSIONS: In surgical treatment of sternal tumors by manubrim sternetomy, the chest wall defects can be constructed with soft materials. After resection of sternal body tumors and subtotal sternectomy, the thoracic wall defects need to be reconstructed with rigid materials.

OBJECTIVE: To compare the short-term outcomes of surgical treatment for non-small cell lung cancer (NSCLC) by video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT). METHODS: Data of 737 consecutive NSCLC patients who underwent surgical treatment for non-small cell lung cancer by video-assisted thoracoscopic surgery and 630 patients who underwent pulmonary resection via open thoracotomy (as controls) in Cancer Institute & Hospital, Chinese Academy of Medical Sciences between January 2009 and August 2011 were retrospectively reviewed. The risk factors after lobectomy were also analyzed. RESULTS: In the 506 NSCLC patients who received VATS lobectomy, postoperative complications occurred in 13 patients (2.6%) and one patient died of acute respiratory distress syndrome (0.2%). In the 521 patients who received open thoracotomy (OT) lobectomy, postoperative complications occurred in 21 patients (4.0%) and one patient died of pulmonary infection (0.2%). There was no significant difference in the morbidity rate (P > 0.05) and mortality rate (P > 0.05) between the VATS group and OT group. In the 190 patients who received VATS wedge resections, postoperative complications occurred in 3 patients (1.6%). One hundred and nine patients received OT wedge resections. Postoperative complications occurred in 4 patients (3.7%). There were no significant differences for morbidity rate (P = 0.262) between these two groups, and there was no perioperative death in these two groups. Univariate and multivariate analyses demonstrated that age (OR = 1.047, 95%CI: 1.004 - 1.091), history of smoking (OR = 6.374, 95%CI: 2.588 - 15.695) and operation time (OR = 1.418, 95%CI: 1.075 - 1.871) were independent risk factors of postoperative complications. CONCLUSIONS: To compare with the NSCLC patients who should undergo lobectomy or wedge resection via open thoracotomy, a similar short-term outcome can be achieved via VATS approach.

OBJECTIVE: To explore the clinical features and surgical management of esophageal gastrointestinal stromal tumors (GIST). METHODS: The clinical data of patients with esophageal GISTs undergoing surgery at our hospital between January 1999 and April 2012 were retrospectively reviewed. RESULTS: Of 14 patients, the male: female ratio was 8:6; the median age of the patients was 42 years (range 33 - 63 years). Dysphagia was the most common symptom, and all cases were diagnosed postoperatively. The tumors were resected by enucleation or esophagectomy or endoscopic submucosal resection. The median follow-up was 43.5 months, ranging from 2 to 142 months, with all patients have no recurrence and metastasis. CONCLUSION: Esophageal GIST is rather rare. At present, surgical resection and postoperative diagnosis remain the mainstay for treatment of patients with esophageal GISTs in China.

OBJECTIVE: As a rare benign lung tumor, pulmonary sclerosing hemangioma (PSH) occurs predominantly in Asian women in their fifth and sixth decades of life. PSH is considered to be evolved from primitive undifferentiated respiratory epithelium. In this study, we summarized our experience in 89 cases of PSH. METHOD: There were a total of 89 patients who received surgical resection and were histopathologically diagnosed as PSH during the period January 2001 to December 2010 in department of thoracic surgery, Cancer Institute and Hospital, Peking Union Medical College and Chinese Academy of Medical Sciences. The clinical data of these patients including symptoms, disease courses, image characteristics and surgical procedures were collected and reviewed retrospectively. RESULTS: The PSHs were most frequently (50.6%) found in the patients aged 41 to 60 years with a median age of 51 years (range: 24 - 71), and the sex ratio (male/female) was approximately 1:7 in this series. In the 89 patients, 53 (59.6%) were asymptomatic while the other 36 (40.4%) had some non-special symptoms such as cough (30.3%), hemoptysis (24.7%). There were only 3 cases (3.4%) with multiple PSHs, 4 cases (4.5%) combined with synchronous primary lung cancer, and 13 cases (14.6%) with lesions located in the hilar region. The median diameter of the 92 lesions was 2.3 cm (range: 0.3 - 6.0 cm), of which 38% located in the right lower lobe and 26.1% in the right middle lobe, and only about 1/3 were assumed as PSHs preoperatively based on CT imaging. One of the five patients who underwent PET-CT scan had been misdiagnosed as malignant. Of the 92 lesions, 47 were resected by enucleation, 29 by wedge resection, 14 by lobectomy, and 2 by pneumonectomy. CONCLUSION: PSH frequently occurs in the middle-aged women. Most individuals with PSH are asymptomatic or have some non-specific symptoms. Their lesions are usually found accidentally by chest imaging. Although PSH often shows typical imaging characteristics of benign neoplasm of the lung, it is difficult to establish a defined pathological diagnosis preoperatively. The significant error or deferred rate of intraoperative frozen-section evaluation for PSH may result in some unnecessarily extensive surgical procedures. The complete surgical resection is considered the only effective treatment for PSH, and the normal pulmonary tissue should be reserved as possible.

OBJECTIVE: To explore the pathoclinical features of adult primary mediastinal liposarcoma and their correlation with the prognosis. METHODS: The clinical data of 19 patients with adult primary mediastinal liposarcoma who were treated in our hospital between 1970 and 2011 were retrospectively analyzed. Eighteen patients underwent open thoracic tumor excisions for at least one time, and the remaining one patient only received biopsy surgery. Histopathological results after surgery revealed that 6 well-differentiated type tumors, 6 myxoid type tumors, 3 pleomorphic type tumors, 2 mixed type tumors, and 2 un-classified tumors. RESULTS: Among 6 patients with well-differentiated type tumors, 1 died after having been survived for 10 years; 5 were still alive, with a mean duration of 126.2 months,the 5-year survival rate was 100%. Among 6 patients with myxoid type tumors, 5 patients had follow-up data, with a mean survival of 26.2 months. Among 3 patients with pleomorphic type tumors, only one patient had follow-up data: the patient finally died, with a survival of 34 months. Of 2 patients with mixed type tumors, only one patient had follow-up data: the patient survived 8 months and died. Of 2 patients with un-classified type tumors, one had follow-up data: the patient lived for 24 months and died. CONCLUSIONS: Mediastinal liposarcoma is a rare disease. Surgery is the primary therapeutic modality. Different pathological subtypes have different epidemiological features, biological behaviors, and malignant potentials. Pathological subtype is an important prognosis factor. Patients with well-differentiated tumors have much better prognosis than those with other subtypes.

OBJECTIVE: To investigate the outcome for surgical treatment of bilateral thoracotomy in patients with lesions of left main bronchus invading carina by bilateral thoracotomy. METHODS: The clinical data of 4 patients with lesions of left main bronchus invading carina undergoing bilateral thoracotomy were retrospectively reviewed. RESULTS: There were two male and two female patients with a median age of 37.5 (range: 27 - 55) years old. Four patients were all accessed by bilateral thoracotomy, and received carinal reconstruction. Of these 4 patients, three patients received left pneumonectomy and one patient received carinal resection without concomitant pulmonary resection. Pathological results showed that one patient had tuberculosis. And other three patients were of 1 squamous cell carcinoma and 2 adenoid cystic carcinomas. Three patients received mechanical ventilation for a period of 3 - 21 days. one patient died of anastomotic dehiscence at 5 days postoperatively. CONCLUSION: Bilateral thoracotomy is an alternative approach for relatively young patients with decent cardiopulmonary functions with lesions of left main bronchus invading carina. Operation type should be based on histopathological type and length of involved left main bronchus.

OBJECTIVE: To evaluate the diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in cases of undiagnosed intrapulmonary lesions. METHODS: A total of 89 patients with intrathoracic lesions underwent EBUS-TBNA, including 56 pulmonary lesions, 7 lymph node staging in lung cancer patients, 21 unknown hilar and/or mediastinal lymphadenopathies and 5 mediastinal tumors. All samples were evaluated for cytological and pathological examinations. RESULTS: No complication of EBUS-TBNA was observed. Among 89 cases, 76 had positive results, 5 negative and 5 cases excluded as unsatisfied samples. In 56 patients with pulmonary lesions, EBUS-TBNA demonstrated 45 malignant tumors, 5 benign diseases, 3 suspicious cancers, 1 negative and 2 unsatisfied samples. In 7 lung cancer patients staged by EBUS-TBNA, 5 showed metastasis and 2 showed no metastasis. In 21 cases with mediastinal and/or hilar lymphadenopathy, EBUS-TBNA demonstrated 3 malignant tumors, 13 benign diseases, 2 negative and 3 unsatisfied samples. All 5 mediastinal lesions were malignant. Three suspicious cancers were confirmed, 1 by CT-guided percutaneous transthoracic needle biopsy and 2 by clinical follow-ups. In 2 lung cancer patients EBUS-TBNA showed negative, 1 surgical sample showed metastasis and another no metastasis by PET-CT. Three negative cases were diagnosed as benign by clinical follow-ups. The diagnostic sensitivity, specificity, positive predictive value and negative predictive value of EBUS-TBNA were 95%, 100%, 100% and 20% respectively. CONCLUSION: EBUS-TBNA is both effective and safe in making a diagnosis of intrathoracic lesions.

OBJECTIVE: To evaluate the indication and safety of video assisted thoracic surgery (VATS) for chest tumors. METHODS: Data of 144 consecutive patients receiving VATS between January and November 2009 in Cancer hospital Chinese Academy of Medical Sciences were retrospectively reviewed. RESULTS: There was no conversion to open thoracotomy. Overall morbidity rate was 2.08% (3/144) and mortality rate was 0.69% (1/144). There were no significant differences for operative time, number of nodal dissection, morbidity rate, mortality rate, overall hospitalization and postoperative length of stay between VATS lobectomy group and open thoracotomy (OT) lobectomy group. Chest tube duration was shorter in the VATS lobectomy group than OT lobectomy group and more early-stage lung cancer patients were found in VATS group. There were no significant differences for number of nodal dissection, chest tube duration, morbidity rate, mortality rate, and postoperative length of stay between VATS lung wedge resection group and OT lung wedge resection group. Operative time and overall hospitalization were shorter in the VATS wedge resection group than OT wedge resection group. CONCLUSION: Morbidity and mortality rate of VATS were acceptable. VATS lobectomy can be used as an alternative surgical technique for early-stage lung cancer. For lung wedge resection, VATS was superior than OT.

OBJECTIVE: To evaluate the value of transbronchial needle aspiration (TBNA) combined with transesophageal endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the diagnosis of mediastinal and pulmonary hilar lesions as well as in the lymph node staging (N staging) of lung cancer. METHODS: 129 patients with mediastinal and pulmonary hilar lesions underwent either TBNA or EUS-FNA with cytological needle aspiration. The samples obtained from TBNA or EUS-FNA were examined by both cytologiy and histopathology. RESULTS: Of the 129 patients, 59 underwent TBNA and 70 EUS-FNA. The diagnostic rate were 84.7% (50/59) by TBNA and 94.3% (66/70) by EUS-FNA, resepectively. The diagnosis of 116 (89.9%) patients were confirmed by either TBNA or EUS-FNA. The pathological and cytological diagnostic rates were 92.2% (107/116) and 88.0% (102/116), resepectively. The diagnostic rate was elevated by 8.4% (9/107) through pathological examination. The histological classification rates by cytological and pathological examination were 73.8% (76/116) and 89.3% (92/103), respectively. The diagnostic rate of histological classification was elevated by 35.5% (27/76) through pathological examination. CONCLUSION: The combination of TBNA and EUS-FNA can improve the diagnostic rate for wider mediastinal and pulmlonary hilar lesions. Pathological examination of the samples obtained from the TBNA and EUS-FNA can elevate not only the rate of diagnosis but also the rate of histological classification.

OBJECTIVE: To assess the presentation, imaging features, and prognostic factors of primary soft tissue sarcoma of mediastinum. METHODS: The clinical data of 22 patients with primary soft tissue sarcoma of mediastinum, 12 males and 10 females, aged 46 (28-69), hospitalized over 27 years were retrospectively reviewed, focusing on the clinical presentations, preoperative diagnosis, imaging features, immunohistochemical studies, treatment, and survival. RESULTS: Chest pain, dyspnea, cough, and shoulder pain were the most common complaints. Imaging findings showed large lobulated mass. The overall 5-year survival rate was 62. 8%. The 5-year survival rate of the patients with tumors larger than 10 cm was 65.6%, significantly higher than that of the patients with tumors smaller than 10 cm (38.8% , P = 0. 019). The long-term survival rate of the patients who received complete resection was 84 months , longer, though not significantly, than that of the patients who received incomplete resection (8 months, P = 0.059). The 5-year survival rate of the patients with lesions at high grade and stage III were 38.2% and 38.2% respectively, both lower, though not significantly, than those of lesions at low grade and stage I (60% and 60% respectively, both P =0.317). The 5-year survival rate of the patients who received surgery only was 8 months, shorter, though not significantly, than that of the patients who received surgery plus adjuvant therapy (12 months, P = 0.204). CONCLUSION: Tumor size and character of resection are important prognostic factors for primary soft tissue sarcoma of mediastinum.

OBJECTIVE: To analyzed the indication and prognostic factors of surgical treatment of lung cancer invading left atrium and great vessels (T4). METHODS: We retrospectively reviewed the database of 136 T4 lung cancer (tumors invading left atrium and great vessels) patients who received surgical treatment in Cancer Hospital of Chinese Academy of Medical Science (CAMS) from September 1981 to January 2007. There are 114 men and 22 women, the median age was 58 years (range 28 - 76). All patients were divided into three subgroups according to the invading site: tumor invading left atrium group, tumor invading superior vena cava group and tumor invading pulmonary artery group. All patients were divided into two subgroups according to the character of operation: complete resection group and incomplete resection group. Patients were divided into three subgroups according to pathological lymph node status: N0, N1 and N2 group. RESULTS: One hundred and thirty six lung cancer patients received resection of primary lesions plus arterioplasty of pulmonary artery (PA) (n = 83) and/or angioplasty of superior vena cava (SVC) (n = 21) and/or partial resection of left atrium (LA) (n = 32). Complete resection was possible in 120 patients and 16 patients underwent incomplete resection. Five-year survival was 43.0% for entire group, 52. 8% for PA group, 18.2% for SVC group and 18.4% for LA group. Factors significantly influencing the overall 5-year survival were the pathologic N status (5-year survival 15.1% for N2, 5-year survival 44.9% for N1, 5-year survival 74% for N0 group; N2 versus N1 versus N0, P = 0.028) and the completeness of resection (5-year survival 37.5% for complete resection, 5-year survival 22.4% for incomplete resection group; complete versus incomplete, P = 0.042). Pathological lymph node status but not histology and character of operation was an independent prognostic factor using Cox regression analysis (P = 0.01, RR = 1.923, 95% CI: 1.172 -3. 157). CONCLUSION: Pathological lymph node status is an independent prognostic factor for T4 lung cancer. Patients with pathological N0-1 lung cancer invading left atrium and great vessels (T4) may benefit from surgical treatment. In the preoperative workup, every possible effort should be made to achieve a careful evaluation of mediastinal lymph noda status. Compared with incomplete resection group, complete resection group may have a better prognosis. Tumor invading extrapericardial PA may be defined as T2.

OBJECTIVE: To explore the methods of the treatment and the principles of the prevention of bronchus-pleural fistula (BPF) after pneumonectomy. METHODS: The clinical data of 15 cases of BPF after pneumonectomy in 815 lung cancer cases treated from July 1999 to June 2006 were analyzed retrospectively. RESULTS: The occurrence rate of BPF after right pneumonectomy was 3.9% (12/310), higher than 0.6% (3/505) of left pneumonectomy (P < 0.01). The occurrence rate of BPF in cases with positive cancer residues in stump of bronchus was 22.7% (5/22), higher than 1.3% (10/793) of the cases with negative stump of bronchus (P < 0.01). The occurrence rate of BPF in the cases received preoperative radio- or chemotherapy was 5.0% (6/119), higher than 1.3% (9/696) of the cases received operation only (P < 0.05). There were no BPF occurred in the 76 cases whose bronchial stump were covered with autogenous tissues. All of the cases diagnosed as BPF were undertaken either closed or open chest drainage. Two cases were cured by thoracentesis aspiration and infusion antibiotics repeatedly. Two cases were cured by blocking the fistula with fibrin glue after sufficient anti-inflammatory treatment and hypertonic saline flushing. Six cases were discharged with a stable condition after closed drainage only. One case was discharged with open drainage for long time and 1 case was cured by hypertonic saline flushing after failure to cover the BPF using muscle flaps. Three cases died of multi-organs functional failure. CONCLUSIONS: BPF are related to the bronchial stump management and positive or negative residue of tumor at the bronchial stump. Autogenous tissues covering of the bronchial stump is a effective method for decrease the rate of BPF and especially for those patients received preoperative radio- or chemotherapy and right pneumonectomy. It should be performed for early mild cases with repeated thoracentesis aspirations or blocking the fistula with fibrin glue together with antibiotics. Chest closed drainage immediately and flushing with hypertonic saline repeatedly are effective methods for BPF.

BACKGROUND: Primary small cell carcinoma of the esophagus is rare. Although surgery is successful in eradicating local tumor, the five-year survival rate of patients with primary small cell carcinoma of the esophagus after resection is lower than that of patients with primary squamous cell carcinoma of the esophagus. The purpose of this study was to analyze the clinical manifestations, pathological features and treatment of primary small cell carcinoma of the esophagus. METHODS: A total of 73 patients with primary small cell carcinoma of the esophagus who had been treated by surgery from 1984 to 2003 were analyzed retrospectively. RESULTS: In this series, the overall resection rate was 94.5% (69/73), the radical resection rate 89.0% (65/73) and the operative mortality 1.4% (1/73). The 1-, 3- and 5-year survival rates of patients were 50.7%, 13.7% and 8.2%, respectively. CONCLUSIONS: Primary small cell carcinoma of the esophagus is rare with a poor prognosis. Surgical resection is the leading method for patients with stage I or II primary small cell carcinoma of the esophagus. Postoperative chemotherapy is beneficial to these patients. The patients of stage III or IV should be given chemotherapy and radiation therapy.

OBJECTIVE: To investigate the classification, incidence, clinical characteristics, diagnosis and surgical treatment of pulmonary sequestration. METHODS: The clinical data of 23 patients with pulmonary sequestration, 13 males and 10 females, aged 39 (12 - 71), with a course of 3 days to 9 years, hospitalized during the period from May 1974 to November 2006, were reviewed retrospectively. RESULTS: The cases of sequestration were presents which were resected and confirmed by pathology in our department. The incident rate of pulmonary sequestration was 0.29% among the patients who underwent operation during that period. Nineteen (83%) of the 23 patients suffered from interloper pulmonary sequestration and 4 suffered from extralobar pulmonary sequestration. Eighteen of the 23 patients had recurrent pneumonia with the clinical manifestations of cough, fever, and hemoptysis. Fourteen cases got confirmed diagnosis before operation. CONCLUSION: The diagnosis of pulmonary sequestration mainly depends on X-ray, CT and MRI. The sequestration should be removed whenever it is diagnosed.

OBJECTIVE: To evaluate the surgical therapeutic strategy for non-small cell lung cancer (NSCLC) with (N2) mediastinal lymph node metastasis. METHODS: The clinical data of 325 patients with N2 NSCLC treated surgically between 1961 and 1995 were analysed. RESULTS: The over-all 5-year survival rate was 19.6%. Survival was higher in patients with radical resection than with palliative resection, with squamous-cell carcinoma than with adenocarcinoma, with sleeve lobectomy and pneumonectomy than with regular lobectomy, with 1 to 3 mediastinal metastatic lymph nodes than those over 4, and with adjuvant therapy (chiefly postoperative radiotherapy) than without. All these differences were statistically significant (P < 0.05). There was no 5-year survivor in patients with T3 or T4 tumor, nor in those with distant metastasis. CONCLUSION: It is suggested that surgery is the best choice for N2 NSCLC patients with T1 or T2 tumor, with non-adenocarcinoma, and with metastatic mediastinal lymph nodes less than 4 in number. Surgery is probably not a good choice in those with T3 tumor varieties. At operation, radical resection of the tumor and systematic removal of all hilar and mediastinal lymph nodes are essential for disease staging and survival improvement. Adjuvant therapy may improve long-term survival and is especially indicated in patients with residual tumor and/or metastatic mediastinal lymph nodes over 3 in number.
