RESUMO
Metastases pulmonares isoladas de sarcomas de partes moles ocorrem em 20%-50% dos pacientes, e 70% destes pacientes apresentarão doença limitada aos pulmões. A ressecção cirúrgica é bem aceita como tratamento padrão nas metastases de sarcomas de partes moles confinadas aos pulmões, com muitos estudos relatando sobrevida em cinco anos de 305-40%, ssndo que o fator preditor de sobrevida é a ressecção completa. O objetivo deste estudo é determinar as variáveis clínicas e demográficas relacionadas ao tratamento e associadas com a sobrevida global a longo prazo (90 meses) nos pacientes submetidos a metastasectomia pulmonar de sarcomas de partes moles. Uma revisão retrospectiva foi realizada nos pacientes com metastases pulmonares que foram submetidos à toracotomia para ressecção das metástases, após o tratamento do tumor primário. Os dados foram coletados de acordo com as características do tumor primário, dados demográficos, tipo de tratamento e evolução. Pacientes (n=77) com sarcomas de partes moles previamente tratados foram submetidos a um total of 122 toracotomias e 273 nódulos ressecados. O seguimento mediando de todos os pacientes foi de 36.7 meses (variação: 10-138 meses). O índice de complicações pós-peratórias foi 9.1%, e a mortalidade em 30 dias de 0%. A sobrevida global em 90 meses para todos os pacientes foi de 34.7%. A análise multivariada identificou o número de metástases, o intervalo livre de doença, e ressecção completa, como fatores prognósticos independentes para a sobrevida global. Estes resultados confirmam que a metastasectomia pulmonar é um procedimento seguro e com potencial curativo para pacientes com tumors primários tratados. Um grupo seleto de pacientes pode apresentar uma sobrevida a longo prazo interessante após a ressecção pulmonar.
Isolated pulmonary metastases from soft tissue sarcomas occur in 20%-50% of these patients, and 70% of these patients will have disease limited only to the lungs. Surgical resection is well accepted as a standard approach to treat metastases from soft tissue sarcomas isolated to the lungs, with many studies reporting overall 5-year survival ranging from 30% to 40%, and the most consistent predictor of survival in these patients is complete resection. The aim of this study is to determine demographics and clinical treatment-related variables associated with long-term (90-month) overall survival in patients with lung metastases undergoing pulmonary metastasectomy from soft tissue sarcomas. A retrospective review was performed of patients who were admitted with lung metastases and underwent thoracotomy for resection, after treatment of the primary tumor. Data were collected regarding primary tumor features, demographics, treatment, and outcome. Patients (n=77) with preview soft tissue sarcomas treated, were submitted to a total of 122 thoracotomies and 273 nodules resected. Median follow-up time of all patients was 36.7 months (range: 10-138 months). The postoperative complication rate was 9.1%, and the 30-day mortality rate was 0%. The 90-month overall survival rate for all patients was 34.7%. Multivariate analysis identified the number of metastases resected, disease-free interval, and complete resection as the independent prognostic factors for overall survival. These results confirm that lung metastasectomy is a safe and potentially curative procedure for patients with treated primary tumors. A select group of patients can achieve long-term survival after lung resection.

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 (3 cases); 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.

OBJETIVO: Identificar características pré-operatórias associadas à ressecção cirúrgica completa de tumores malignos primários do mediastino. MÉTODOS: Entre os anos de 1996 e 2006, 42 pacientes com tumores malignos primários do mediastino foram submetidos a tratamento cirúrgico com intenção curativa em uma única instituição. Dados demográficos, manifestações clínicas, características do tumor mediastinal e aspectos de invasão por métodos de imagem foram identificados através da análise de prontuários. RESULTADOS: A ressecção cirúrgica foi considerada completa em 69,1 por cento dos pacientes. As causas de ressecção incompleta foram atribuídas à invasão das seguintes estruturas: grandes vasos (4 casos); veia cava superior (3 casos); coração (2 casos); pulmão e parede torácica (3 casos); e traqueia (1 caso). Os pacientes que foram submetidos à ressecção cirúrgica completa tiveram sobrevida global significativamente melhor que os pacientes submetidos à ressecção incompleta. A frequência de ressecção incompleta foi significativamente maior nos casos nos quais foram identificadas características radiológicas de invasão de outros órgãos além do pulmão do que nos casos cujas características eram restritas ao pulmão (47,6 por cento vs. 14,3 por cento; p = 0,04). Nenhuma das outras características pré-operatórias analisadas foi associada com a ressecção cirúrgica completa. CONCLUSÕES: Evidências radiológicas de invasão de órgãos além do pulmão no pré-operatório estão associadas à ressecção cirúrgica incompleta de tumores primários malignos do mediastino.

BACKGROUND: Symptomatic pericardial effusion in patients with cancer may lead to a life-threatening event that requires diligent treatment, but the best surgical treatment is still controversial. The purpose of this study was to identify predictors of survival for patients with solid malignancies and symptomatic pericardial effusion, which might help to select the best surgical treatment for each patient. METHODS: We retrospectively analyzed 47 patients with solid malignancies concomitant with symptomatic pericardial effusion who underwent surgery between 1994 and 2004. Overall survival was calculated from date of surgery, and prognostic importance of clinical and pathological variables was assessed. RESULTS: The most common primary sites of disease were breast (46.8%) and lung (25.6%). Initial pericardiocentesis were performed in 29 patients; median volume of fluid drained was 480 mL. Median interval from the diagnosis of primary cancer to the development of pericardial effusion (pericardial effusion-free interval) was 34.8 months. Definitive surgical treatment was performed in 43 patients, as follows: subxiphoid pericardial window (n = 21); thoracotomy and pleuropericardial window (n = 10); pericardiodesis (n = 8); and videothoracoscopic pleuropericardial window (n = 4). Pericardiocentesis was the only procedure in four patients. Median follow-up was 2.9 months. Median overall survival was 3.7 months. Pericardial effusion-free interval longer than 35 months and more than 480 mL of fluid drained at initial pericardiocentesis were determinants of better survival. CONCLUSIONS: Pericardial window and pericardiodesis seem to be safe and efficacious in treating effusion of the pericardium. Pericardial effusion-free interval and volume drained at initial pericardiocentesis are determinants of outcome.
