Objective: To analyze determinants of prognosis in patients with bronchial carcinoid tumors treated surgically and the potential concomitance of such tumors with second primary neoplasms. Methods: This was a retrospective analysis of 51 bronchial carcinoid tumors treated surgically between 2007 and 2016. Disease-free survival (DFS) was calculated by the Kaplan-Meier method, and determinants of prognosis were evaluated. Primary neoplasms that were concomitant with the bronchial carcinoid tumors were identified by reviewing patient charts. Results: The median age was 51.2 years, 58.8% of the patients were female, and 52.9% were asymptomatic. The most common histology was typical carcinoid (in 80.4%). Five-year DFS was 89.8%. Ki-67 expression was determined in 27 patients, and five-year DFS was better among the patients in whom Ki-67 expression was ≤ 5% than among those in whom it was > 5% (100% vs. 47.6%; p = 0.01). Concomitant primary neoplasms were observed in 14 (27.4%) of the 51 cases. Among the concomitant primary neoplasms that were malignant, the most common was lung adenocarcinoma, which was observed in 3 cases. Concomitant primary neoplasms were more common in patients who were asymptomatic and in those with small tumors. Conclusions: Surgical resection is the mainstay treatment of bronchopulmonary carcinoid tumors and confers a good prognosis. Bronchial carcinoid tumors are likely to be accompanied by second primary neoplasms.

Background: Lobectomy is still considered the most effective method of controlling primary lung tumors. Method: During the period from 1995 to 2000, 733 cases of non-small cell bronchial carcinoma. After clinical evaluation and surgical staging, 191 patients were submitted to surgical resection. Of those 191 surgeries, 63 were for locally advanced tumors and 128 (69 segmentectomies and 59 lobectomies) for primary tumors. Post-operative FEV1 of at least 800 ml was used as a measure of surgical success. Extended segmentectomies, in which the resection passes the intersegmental line, including the parenchyma of the adjoining segment, were used. Results: Among the 128 patients with primary tumors, there were 3 deaths and 10 patients fell out of contact. Therefore, 62 segmentectomies and 53 lobectomies were evaluated. There were 72 adenocarcinomas and 43 epidermoid carcinomas. The 5-year survival of lobectomy patients was 80% (T1N0), 72.7% (T2N0), 50% (T1N1) and 31.8% (T2N1), whereas that of segmentectomy patients was 80% (T1N0), 66.6% (T2N0), 41.1% (T1N1) and 30% (T2N1) (p > 0.05). Tumor size and enlarged interlobar lymph nodes were prognostically significant (p < 0.001), although method of resection influenced neither survival nor local or remote recurrence (p > 0.05). Conclusion: Extended segmentectomy represents an alternative treatment for primary tumors in patients with limited lung reserve.

Purpose: To assess the results of the surgical treatment of primary spontaneous pneumothorax (PSP) by means of axillary thoracotomy, blebs resection and abrasive pleurodesis, by comparing the results with the different options of treatment, and to discuss the surgical approach as the best therapeutic option for patient with the first occurrence of PSP. Material and methods: 35 axillary thoracotomy with abrasive pleurodesis for the treatment of PSP were carried out at the Department of Thoracic Surgery of the University of Caxias do Sul between January 1996 and March 1999. Results: 23 patients with their first episode of PSP and 12 patients in their second episode were treated. The pleural drains were kept for in an average period of 2.7 ± 1.6 days. The average time in hospital was about 4.9 ± 2.4 days. Morbidity was 8.5% and mortality rate was zero. There was no relapse in an average period of 22 months of follow-up. Conclusion: The indication of axillary thoracotomy and abrasive pleurodesis to the patients with primary spontaneous pneumothorax (PSP) at the first or recurrent episode showed low rates of morbidity and no relapse, besides short periods of hospitalization and pleural drain permanence. The possibility of indication as the first therapeutic method for the PSP should be considered.

Objectives: Thoracoscopic management of mediastinal tumors is still subject to analysis. Seventy-three patients were submitted to thoracoscopy for the treatment of mediastinal masses and were analyzed retrospectively, in order to evaluate the effectiveness and complications of the procedure. Methods: Between 1983 and 1999, 21 conventional thoracoscopies and 52 video-assisted thoracic surgeries were performed (33 for diagnostic purposes and 40 for therapy). Patient ages ranged from two to 81 years (mean 43.8) with a slight predominance of females over males (41 versus 32). All underwent general anesthesia using simple (22) or double lumen (51) intubation. Results: The histological type of tumor was identified in all patients. For therapeutic purposes, conversion to thoracotomy was necessary in nine patients. The reasons were tumor size and invasion of nearby structures, difficulty to continue dissection, to perform an upper lobectomy, and to suture the iatrogenic diaphragm lesion. Four patients died during the first 30 postoperative days as a consequence of their primary pathology. Conclusions: Thoracoscopy was confirmed to be an effective diagnostic and therapeutic alternative for the treatment of mediastinal disorders.

Objective: To identify preoperative characteristics associated with complete surgical resection of primary malignant mediastinal tumors. Methods: Between 1996 and 2006, 42 patients with primary malignant mediastinal tumors were submitted to surgery with curative intent at a single facility. Patient charts were reviewed in order to collect data related to demographics, clinical manifestation, characteristics of mediastinal tumors and imaging aspects of invasiveness. Results: The surgical resection was considered complete in 69.1% of the patients. Cases of incomplete resection were attributed to invasion of the following structures: large blood vessels (4 cases); the superior vena cava (3 cases); the heart (2 cases); the lung and chest wall (3cases); and the trachea (1 case). Overall survival was significantly better among the patients submitted to complete surgical resection than among those submitted to incomplete resection. The frequency of incomplete resection was significantly higher in cases in which the tumor had invaded organs other than the lung (as identified through imaging studies) than in those in which it was restricted to the lung (47.6% vs. 14.3%; p = 0.04). None of the other preoperative characteristics analyzed were found to be associated with complete resection. Conclusions: Preoperative radiological evidence of invasion of organs other than the lung is associated with the incomplete surgical resection of primary malignant mediastinal tumors.

Background: Lung cancer is the leading cause of cancer-related death worldwide. Objective: To determine the time spent diagnosing, staging and surgically treating lung cancer in a university hospital. Method: Between January 1990 and December 1998, 69 (53 male, 16 female) patients were diagnosed with lung cancer and underwent surgery. The hospital records of these patients were reviewed to evaluate clinical and histological data, dates of outpatient visits, hospital admission, tests and procedures, as well as to determine if the patients were examined as inpatients or as outpatients. Results: The 15 patients investigated as outpatients were designated as group I, the 28 examined as both inpatients and outpatients as group II, and the 26 investigated as inpatients as group III. Age ranged from 43 to 79 years (mean ± SD; 61 ± 10). Of the 69 patients, 43 were smokers and 23 were ex-smokers. The mean time from onset of symptoms to the first outpatient visit was 110 days and 33 days from the first outpatient visit until diagnosis. There was a lapse of 25 days between diagnosis and surgery. The mean total elapsed time between the first outpatient visit and surgery was 58 days. The mean total time was 72 days for group I, 72 days for group II, and 35 days for group III (p < 0.01). There was no significant difference regarding total time in relation to the different stages of the disease (p = 0.16). Conclusions: The results show that patients waited too long before seeking medical assistance and that medical treatment of lung cancer was further delayed when patients were examined in an outpatient setting.

The objective of this study was to analyze the outcome of surgical treatment of pulmonary aspergilloma. To that end, we evaluated 14 adult patients so treated between 1981 and 2009 at the Botucatu School of Medicine University Hospital, in the city of Botucatu, Brazil. Data were collected from the medical records of the patients. Ten patients (71%) presented with simple pulmonary aspergilloma, and 4 (29%) presented with complex pulmonary aspergilloma. Hemoptysis was the most common symptom, and tuberculosis was the most prevalent preexisting lung disease. Two patients (14%) underwent surgery on more than one occasion. There were no intraoperative deaths. Half of the patients developed postoperative complications, prolonged air leak and empyema being the most common.

Objective: To analyze tuberculosis treatment outcomes and their predictors. Methods: This was a retrospective longitudinal cohort study involving tuberculosis patients treated between 2004 and 2006 at the Instituto de Pesquisa Evandro Chagas, in the city of Rio de Janeiro. We estimated adjusted risk ratios (ARRs) for the predictors of treatment outcomes. Results: Among 311 patients evaluated, the rates of cure, treatment abandonment, treatment failure, and mortality were 72%, 19%, 2%, and 6%, respectively. Changes in the treatment regimen due to adverse events occurred in 8%. The factors found to reduce the probability of cure were alcoholism (ARR, 0.30), use of the streptomycin+ethambutol+ofloxacin (SEO) regimen (ARR, 0.32), HIV infection without the use of antiretroviral therapy (ART; ARR, 0.36), and use of the rifampin+isoniazid+pyrazinamide+ethambutol regimen (ARR, 0.58). Being younger and being alcoholic both increased the probability of abandonment (ARR, 3.84 and 1.76, respectively). It was impossible to determine the ARR for the remaining outcomes due to their low prevalence. However, using the relative risk (RR), we identified the following potential predictors of mortality: use of the SEO regimen (RR, 11.43); HIV infection without ART (RR, 9.64); disseminated tuberculosis (RR, 9.09); lack of bacteriological confirmation (RR, 4.00); diabetes mellitus (RR, 3.94); and homosexual/bisexual behavior (RR, 2.97). Low income was a potential predictor of treatment failure (RR, 11.70), whereas disseminated tuberculosis and HIV infection with ART were potential predictors of changes in the regimen due to adverse events (RR, 3.57 and 2.46, respectively). Conclusions: The SEO regimen should not be used for extended periods. The data confirm the importance of ART and suggest the need to use it early.

Objective: To evaluate the effect that the distribution of food baskets to tuberculosis (TB) patients has on treatment outcomes at a primary health care clinic. Methods: Retrospective comparative study of the medical and social aspects of 142 patients at a primary health care clinic in the city of Duque de Caxias, Brazil. The patients were divided into two groups: the first group included 68 patients treated with standard regimens (between September of 2001 and December of 2003); and the second group included 74 patients treated with the same regimens but also receiving food baskets on a monthly basis (between January of 2004 and July of 2006). Results: The statistical comparison between the two groups revealed that the cure rate was higher in the group receiving the food baskets (87.1% vs. 69.7%), whereas the rate of noncompliance was markedly lower (12.9% vs. 30.3%). Conclusions: The results indicate that the distribution of food baskets can be a useful strategy to improve compliance with TB treatment at primary health care clinics.

Objective: To analyze the association of dysglycemia with clinical, laboratory, and radiographic characteristics of patients with pulmonary tuberculosis (PTB), as well as with their tuberculo-sis treatment outcomes. Methods: This was a longitudinal study involving 140 patients diag-nosed with PTB (positive cultures for Mycobacterium tuberculosis or positive Xpert MTB/RIF results from sputum samples). Patients were evaluated at diagnosis (M0), after completing the second month of treatment (M2), and at the end of treatment (MEND). At M0, the pati-ents were classified into three groups: normoglycemia+PTB (NGTB); pre-diabetes melli-tus+PTB (PDMTB), and diabetes mellitus+PTB (DMTB), in accordance with glycated hemoglo-bin levels (< 5.7%, 5.7%-6.4%, and = 6.5%, respectively). Treatment outcomes were classified as favorable (cure or treatment completion) and unfavorable (death, loss to follow-up, or treatment failure). Results: In our sample, 76 patients (61.4%) had dysglycemia, 20 of whom (14.3%) had DM at M0. The patients with dysglycemia, in comparison with those in the NGTB group, more frequently presented with positive sputum smear microscopy (94.2% vs. 75.9%; p = 0.003); cavities (80.2% vs. 63.0%; p = 0.03); bilateral lesions (67.4% vs. 46.0%; p = 0.02); and higher median of affected thirds of the lungs (3.0 vs. 2.0; p = 0.03) on chest radiography. No significant differences regarding outcomes were found among the groups, but tuberculosis lethality was higher in the DMTB group than in the PDMTB and NGTB groups (20% vs. 2.2%). Conclusions: PTB patients with dysglycemia had laboratory and radiographic manifestations indicative of more advanced disease, and the risk of death was higher in the DMTB group. These findings reinforce the recommendation for early screening for DM in patients with newly diagnosed tuberculosis in order to reduce the risk of death during treatment.

Pulmonary sequestration is defined as a mass of lung tissue separated from the tracheobronchial tree and irrigated by an anomalous systemic artery. It is rarely seen in conjunction with lung neoplasms. We report the case of a 39-year-old female patient diagnosed with a carcinoid tumor, located in the intermediate bronchus and accompanied by bronchiectasis in the right lower lobe. The patient underwent thoracotomy for the resection of the affected area. During surgery, she presented with significant hemorrhage resulting from the transection of the anomalous artery that irrigated an intralobar pulmonary sequestration, which was located in right lower lobe and had not been identified in pre-operative examinations.

Objective: To analyze the outcomes of patients undergoing repair of congenital tracheal stenosis. Methods: This was a retrospective review of congenital tracheal stenosis patients treated between 2001 and 2007 at the University of São Paulo School of Medicine Hospital das Clínicas in São Paulo, Brazil. Results: Six boys and one girl (age at diagnosis ranging from 28 days to 3 years) were included. Five of the patients also had cardiac or major vessel malformations. The stenosis length was short in three patients, medium in one and long in three. The techniques used were pericardial patch tracheoplasty in three patients, resection and anastomosis in two, slide tracheoplasty in one and vascular ring correction in one. One patient died during surgery due to hypoxia and hemodynamic instability, and one died from septic shock on postoperative day 11. Other complications included pneumonia, arrhythmia, stenosis at the anastomosis level, residual stenosis, granuloma formation and malacia. The mean follow-up period was 31 months; four patients were cured, and one required the use of a T-tube to maintain airway patency. Conclusions: Congenital tracheal stenosis is a curable disease. However, its repair is complex and is associated with high rates of morbidity and mortality.

Objective: To describe the results of the surgical treatment of children with necrotizing pneumonia. Methods: A retrospective analysis of the medical charts of 20 children diagnosed with necrotizing pneumonia and submitted to surgical treatment between March of 1997 and September of 2008 in the thoracic surgery departments of two hospitals in the city of Manaus, Brazil. We compiled data regarding age, gender, etiologic agent, indications for surgery, type of surgical resection performed, and postoperative complications. Results: The mean age of the patients was 30 months. Of the 20 patients studied, 12 (60%) were female. The most common etiologic agents were Staphylococcus aureus, in 5 patients (25%), and Klebsiella sp., in 2 (10%). The indications for surgery were sepsis, in 16 patients (80%), and bronchopleural fistula, in 4 (20%). The types of surgical procedures performed were lobectomy, in 12 patients (60%), segmentectomy, in 7 (35%), and bilobectomy, in 1 (5%). There were 8 patients (40%) who also underwent decortication. The postoperative complications were as follows: bronchopleural fistula, in 4 patients (20%); empyema, in 1 (5%); pneumatocele, in 1 (5%); and phlebitis of the left arm, in 1 (5%). Four (20%) of the patients died. Conclusions: Surgical resection should be considered in patients with evidence of pulmonary necrosis. Resection is indicated in cases of severe sepsis, high output bronchopleural fistula, or acute respiratory failure that are refractory to clinical treatment.

Objective: To describe demographic characteristics, surgical results, postoperative complications, and overall survival rates in surgically treated patients with lung metastases. Methods: This was a retrospective analysis of 119 patients who underwent a total of 154 lung metastasis resections between 1997 and 2011. Results: Among the 119 patients, 68 (57.1%) were male and 108 (90.8%) were White. The median age was 52 years (range, 15-75 years). In this sample, 63 patients (52.9%) presented with comorbidities, the most common being systemic arterial hypertension (69.8%) and diabetes (19.0%). Primary colorectal tumors (47.9%) and musculoskeletal tumors (21.8%) were the main sites of origin of the metastases. Approximately 24% of the patients underwent more than one resection of the lesions, and 71% had adjuvant treatment prior to metastasectomy. The rate of lung metastasis recurrence was 19.3%, and the median disease-free interval was 23 months. The main surgical access used was thoracotomy (78%), and the most common approach was wedge resection with segmentectomy (51%). The rate of postoperative complications was 22%, and perioperative mortality was 1.9%. The overall survival rates at 12, 36, 60, and 120 months were 96%, 77%, 56%, and 39%, respectively. A Cox analysis confirmed that complications within the first 30 postoperative days were associated with poor prognosis (hazard ratio = 1.81; 95% CI: 1.09-3.06; p = 0.02). Conclusions: Surgical treatment of lung metastases is safe and effective, with good overall survival, especially in patients with fewer metastases.

Objective: To compare inpatient and outpatient treatment of tuberculosis, in terms of outcomes, in the city of São Paulo, Brazil, as well to determine which variables are most frequently associated with hospitalization. Methods: A prospective, longitudinal study carried out between January and December of 2007, at two large hospitals and at outpatient clinics, in two regions of the city of São Paulo. For inpatients, data were collected with a structured questionnaire. Additional data were obtained from the São Paulo State Department of Health Tuberculosis Database. Results: Of the 474 patients included in the study, 166 were inpatients, and 308 were outpatients. The multivariate analysis showed that hospitalization for tuberculosis was associated with hospital/emergency room diagnosis of tuberculosis (OR = 55.42), with HIV co-infection (OR = 18.57), with retreatment (OR = 18.51), and with having previously sought treatment at another health care facility (OR = 12.32). For the inpatient and outpatient groups, the overall cure rates were 41.6% and 78.3%, respectively, compared with 30.4% and 58.5% for those who were co-infected with HIV, whereas the overall mortality rates were 29.5% and 2.6%, respectively, compared with 45.7% and 9.8% for those who were co-infected with HIV. Conclusions: Among inpatients, tuberculosis appears to be more severe and more difficult to diagnose, resulting in lower cure rates and higher mortality rates, than among outpatients. In addition, tuberculosis patients co-infected with HIV have less favorable outcomes.

Objective: Personal experiences, perceptions, and views of patients are crucial in understanding the subjective impacts of diseases. The complexity and duration of tuberculosis treatment impose significant physical, emotional, social, and economic burdens, highlighting the need for person-centered, integrated care strategies that address stigma, fatigue, and accessibility to support well-being. Patient-reported outcomes (PROs) are essential for capturing patient perspectives and improving health care strategies. In this study we explored the multifaceted experiences of patients with tuberculosis, seeking to understand their values and priorities during treatment. Methods: Semistructured interviews with adult tuberculosis patients were conducted at a referral center for tuberculosis diagnosis and management in northern Portugal. After verbatim transcription and anonymization, thematic analysis was performed. Results: Seventeen interviews were conducted. Most (58.8%) of the study participants were male, and most had pulmonary tuberculosis. Our thematic analysis identified five PROs: treatment experiences; health-related quality of life; functional status; symptoms and symptom burden; and health behaviors. People with tuberculosis acknowledged the impact of multiple factors on their overall health, particularly the psychological and physical burdens of tuberculosis and its treatment. Several areas for improvement and opportunities for enhanced support were identified, particularly in communication, emotional support, and management of treatment burden. Conclusions: Our findings highlight the need for tailored PRO measures (PROMs) addressing treatment burden, psychosocial distress, and functional limitations in tuberculosis care. Enhancing communication, psychological support, and multidisciplinary approaches in tuberculosis management could improve patient outcomes and overall well-being. Addressing tuberculosis-related stigma and providing targeted interventions may contribute to a more people-centered approach to care.
