Tuberculosis a disease that created and shaped thoracic surgery.

Today it is incredible to think that an infectious disease, Tuberculosis (TB) as the disease that shaped Thoracic Surgery. The history of TB has so far evolved similarities with that of the mythological Phoenix, where the resurgence of this never completely eradicated "Insidious Disease" has now re-emerged and brought new challenges to modern medicine that of multi drug resistance. The probability of success, in treating complicated multi-drug resistant (MDR) TB pushing us back to the pre-antibiotic era, now depends on several factors: (I) optimal antibiotic management; (II) patient compliance; (III) multi-disciplinary teamwork; (IV) experience in carrying out "not-routine" surgical procedures; and finally (V) ability to offer long term patient hospitalization, frequently months, without bureaucratic and economical problems. The probability of good patient outcome is higher when all of these criteria are satisfied.

Non-small cell lung cancer in surgically treated women.

AIM AND BACKGROUND: To determine whether female patients operated on for non-small cell lung cancer (NSCLC) have a survival advantage compared to male patients. METHODS AND STUDY DESIGN: We analyzed data from 1,426 prospectively collected patients submitted to lung resection for NSCLC between 1999 and 2008. RESULTS: Two groups, including 1,014 male and 412 female patients, were compared. Female patients were significantly younger, were more frequently asymptomatic, were less likely to be smokers, had better preoperative respiratory function, had a lower frequency of COPD, and were less commonly affected by cardiovascular comorbidity than men. Adenocarcinoma was more frequently present and early pathological stage (stage IA) more frequently detected in women at diagnosis. The operative mortality was significantly lower among women (1.6% vs 4.6%) (P = 0.012), and women underwent significantly more segmentectomies and fewer pneumonectomies (P = 0.001). The disease-related 5-year survival rate was significantly higher in women (66% vs 51%) (P = 0.0008). At univariate analysis the absence of symptoms at presentation, lower pathological stage, squamous cell type, and female gender were positive factors influencing long-term survival. At multivariate analysis low pathological stage, squamous cell type and female gender were confirmed as independent positive prognostic predictors. Women had a significant survival advantage irrespective of the histological subtype at pathological stage IA, IB, IIB and IIIA disease (P <0.05). CONCLUSIONS: Female gender was confirmed to be a particular subset amongst patients affected by NSCLC and exerted a positive effect on disease-related survival of patients submitted to surgical resection. This important effect of gender should be cautiously kept in mind in analyzing the results of current and future trials for lung cancer therapy.

Pulmonary aspergilloma: clinical aspects and surgical treatment outcome.

Aspergillomas are fungal balls within lung cavities. The natural history is variable. Hemoptysis is a dangerous sequela. Medical therapy is ineffective because of the lack of a lesion blood supply. Randomized trials are lacking. Surgery should be the treatment of choice in cases of hemoptysis, and even in asymptomatic patients, if lung function is not severely compromised. Cavernostomy and cavernoplasty may be options for high-risk patients. Percutaneous therapy should be reserved for patients who are not fit for surgery. Bronchial artery embolization is appropriate for symptomatic patients not suitable for surgery. Embolization could be considered a preoperative and temporary strategy.

Use of the proposals of the international association for the study of lung cancer in the forthcoming edition of lung cancer staging system to predict long-term prognosis of operated patients.

PURPOSE: To evaluate the utility of the proposals of the International Association for the Study of Lung Cancer (IASLC) in the forthcoming 7th edition of lung cancer staging system to classify patients submitted to radical surgical resection of non-small cell lung cancer and to compare their value in predicting long-term prognosis with the existing 6th edition of the American Joint Committee on Cancer (AJCC)/Union Internationale Contre le Cancer (UICC) TNM classification. METHODS: Nine hundred twenty-one patients received an anatomic resection and hilar-mediastinal dissection for primary non-small cell lung cancer during the period 1990 to 2005. Histopathologic staging following the actual AJCC/UICC TNM classification were as follows: 207 T1, 562 T2, 148 T3, and 4 T4; 570 N0, 149 N1, 198 N2, and 4 N3; 163 stage IA, 346 IB, 23 IIA, 157 IIB, 224 IIIA, and 8 IIIB. Stages reclassified using the proposals of IASLC for the new staging system were as follows: 101 T1a, 106 T1b, 400 T2a, 103 T2b, 210 T3, and 1 T4; 163 stage IA, 262 IB, 157 IIA, 106 IIB, 230 IIIA, and 4 IIIB. RESULTS: Follow-up was obtained for 836 patients. Mean follow-up was 46.5 +/- 48.9 months. N-status (unchanged between the 2 classifications) was confirmed to be a significant prognostic factor. Significant differences in 10-year disease-related survival were demonstrated between stages IIB and IIIA only (35% vs 14%) of the AJCC/UICC TNM classification and between stages IB and IIA (60% vs 46%) and stages IIB and IIIA (39% vs 15%) of the IASLC proposals for a new classification. DISCUSSION: The proposals of IASLC in the forthcoming 7th edition of the lung cancer staging system are demonstrated to be better able to separate prognostically distinct groups of patients operated for non-small cell lung cancer than the accepted existing 6th AJCC/UICC TNM classification.

Open window thoracostomy for pleural empyema complicating partial lung resection.

BACKGROUND: Although an open-window thoracostomy (OWT) represents the ideal method for drainage of postpneumonectomy empyema, several controversies exist concerning its application to pleural empyema complicating pulmonary resections less than pneumonectomy. METHODS: Between January 1993 and December 2003, 19 patients (16 male and 3 female) were treated for a pleural empyema complicating partial lung resection. The median age was 62 years (range, 17 to 79). Five patients (26%) had a bronchopleural fistula. RESULTS: In 2 patients (10%), successful control of the infection was achieved with the OWT. In 10 patients (56%), the OWT was closed by obliteration of pleural cavity with antibiotic solution (2 patients) or intrathoracic muscle transposition (8 patients). OWT closure was successfully performed in all of 5 patients with postoperative pleural empyema due to bronchopleural fistula. Prolonged chest drainage was not successful in any patient with late onset postoperative pleural empyema. Univariate analysis revealed that previous left pulmonary resections (p < 0.05) and timing of OWT (p < 0.001) were significant predictors of empyema healing after pulmonary resections smaller than pneumonectomy. CONCLUSIONS: Immediate OWT is a significant predictor of empyema healing after partial lung resection. Smaller pleural cavities appeared to increase the likelihood of healing. Prolonged chest tube drainage failed to control the infection in late onset of postoperative pleural empyema due to entrapped lung.

Predictors of successful closure of open window thoracostomy for postpneumonectomy empyema.

BACKGROUND: Although the open window thoracostomy (OWT) represents the ideal method for drainage of postpneumonectomy empyema (PPE), several controversies exist concerning its closure. METHODS: Between January 1993 and December 2003, an OWT was created in 31 patients (29 male and 2 female) with PPE. The median age was 61 years (range, 32 to 76). In 26 patients (84%) a bronchial stump fistula developed. The OWT closure was correlated with characteristics of PPE and the timing of OWT. RESULTS: In 15 patients (48%), the OWT could be closed by obliteration of pleural cavity with antibiotic solution (3 patients) or intrathoracic muscle transposition (12 patients). A successful closure was observed in 13 of the 15 patients (87%). All patients closed by Clagett's procedure remained empyema free. Recurrent cancer (n = 4), poor functional status (n = 3), refusal of further operation (n = 2), and persistent tuberculous empyema (n = 2) were common causes of failure of OWT closure. Univariate analysis revealed that the timing of empyema development after surgery (p = 0.02) and the timing of OWT (p = 0.03) were significant predictors of thoracostomy closure. CONCLUSIONS: Late onset of PPE and immediate OWT creation are significant predictors of OWT closure. Smaller dimensions of the pleural cavity appeared to increase the likelihood of closure. When the pleural cavity shows healthy granulation tissue and no bronchopleural fistula, the Clagett's procedure is safe and effective to obliterate the pleural cavity. Obliteration by muscle flap transposition can be reserved for patients with persistent or recurrent bronchopleural fistula.
