RESUMO

The risk of aerosol transmission has been a key factor for the rapid dissemination of the coronavirus pandemic. Transportation of coronavirus disease 2019 (COVID-19)-infected patients with active air leaks could expose unprotected health care personnel and other patients to aerosolized viral particles. We devised a way to avoid aerosolization while the chest tube drain is on water seal. It involves placing an Ultipor100 viral filter on the suction port of the drain system as well as sealing off the safety valve. This mechanism allows positive pressure from an air leak to escape while on water seal while trapping viral particles.

RESUMO

CASE: A 70-year-old woman pedestrian struck by a motor vehicle presented with multiple orthopaedic injuries including a humeral head fracture dislocation with a large segment of humeral head located in the mediastinum. Thoracic surgery personnel performed a minimally-invasive video-assisted thoracoscopic extraction of the humeral head, and the patient underwent subsequent reverse total shoulder arthroplasty. CONCLUSION: Intramediastinal displacement of the humeral head is a rare, yet serious traumatic injury that necessitates early recognition and comanagement with cardiothoracic or thoracic surgery. Early thoracic intervention to extract the humeral head and replacement arthroplasty is an effective treatment modality.

RESUMO

Primary lung adenocarcinomas are rare in pediatric patients, and even rarer in patients without precedent malignancy or congenital malformation. Here we present the first reported case of primary lung cribriform adenocarcinoma with squamoid morules in a previously healthy adolescent female. Molecular testing identified CTNNB1 mutation in the tumor and excluded other common mutations in lung adenocarcinoma. Our case suggests molecular alterations to the same signaling pathway can lead to similar histomorphology regardless of the tissue of origin.

RESUMO

A novel coronavirus pandemic may be particularly hazardous to health care workers. Airway management is an aerosol-producing high-risk procedure. To minimize the production of airborne droplets, including pathogens such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), from the endotracheal tube during procedures requiring lung deflation, we devised a technique to mitigate the risk of infection transmission to health care personnel.

RESUMO

Airleaks are one of the most common complications associated with elective lung resection. There have been many techniques and modern advancements in thoracic surgery, however airleaks persist. This review article will discuss several interventions ranging from conservative noninvasive to surgical management of the persistent airleak. These techniques include stopping of suction on the plueravac, fibrin patches, pleurodesis, use of endobronchial valves (EBVs), return to OR for operative intervention, and lastly to send patients home with mini pleuravacs.

RESUMO

Phase I testing of the hu14.18-IL2 immunocytokine (IC) in melanoma patients showed immune activation, reversible toxicities, and a maximal tolerated dose of 7.5 mg/m2/day. Preclinical data in IC-treated tumor-bearing mice with low tumor burden documented striking antitumor effects. Patients with completely resectable recurrent stage III or stage IV melanoma were scheduled to receive 3 courses of IC at 6 mg/m2/day i.v. on days 1, 2 and 3 of each 28-day course. Patients were randomized to complete surgical resection either following neoadjuvant (Group A) or prior to adjuvant (Group B) IC course 1. Primary objectives were to: (1) evaluate histological evidence of anti-tumor activity and (2) evaluate recurrence-free survival (RFS) and OS. Twenty melanoma patients were randomized to Group A (11 patients) or B (9 patients). Two Group B patients did not receive IC due to persistent disease following surgery. Six of 18 IC-treated patients remained free of recurrence, with a median RFS of 5.7 months (95% confidence interval (CI) 1.8-not reached). The 24-month RFS rate was 38.9% (95% CI 17.5-60.0%). The median follow-up of surviving patients was 50.0 months (range: 31.8-70.4). The 24-month OS rate was 65.0% (95% CI 40.3-81.5%). Toxicities were similar to those previously reported. Exploratory tumor-infiltrating lymphocyte (TIL) analyses suggest prognostic value of TILs from Group A patients. Prolonged tumor-free survival was seen in some melanoma patients at high risk for recurrence who were treated with IC.

RESUMO

BACKGROUND: We describe the second largest contemporary series of flaps used in thoracic reconstruction. METHODS: A retrospective review of patients undergoing thoracomyoplasty from 2001 to 2013 was conducted. Ninety-one consecutive patients were identified. RESULTS: Thoracomyoplasty was performed for 67 patients with intrathoracic indications and 24 patients with chest wall defects. Malignancy and infection were the most common indications for reconstruction (P < 0.01). The latissimus dorsi (LD), pectoralis major, and serratus anterior muscle flaps remained the workhorses of reconstruction (LD and pectoralis major: 64% flaps in chest wall reconstruction; LD and serratus anterior: 85% of flaps in intrathoracic indication). Only 12% of patients required mesh. Only 6% of patients with <2 ribs resected required mesh when compared with 24% with 3-4 ribs, and 100% with 5 or more ribs resected (P < 0.01). Increased rib resections required in chest wall reconstruction resulted in a longer hospital stay (P < 0.01). Total comorbidities and complications were related to length of stay only in intrathoracic indication (P < 0.01). Average intubation time was significantly higher in patients undergoing intrathoracic indication (5.51 days) than chest wall reconstruction (0.04 days), P < 0.05. Average hospital stay was significantly higher in patients undergoing intrathoracic indication (23 days) than chest wall reconstruction (12 days), P < 0.05. One-year survival was most poor for intrathoracic indication (59%) versus chest wall reconstruction (83%), P = 0.0048. CONCLUSION: Thoracic reconstruction remains a safe and successful intervention that reliably treats complex and challenging problems, allowing more complex thoracic surgery problems to be salvaged.

RESUMO

BACKGROUND: The hypothesis that most cancers are of monoclonal origin is often accepted as a fact in the scientific community. This dogma arose decades ago, primarily from the study of hematopoietic malignancies and sarcomas, which originate as monoclonal tumors. The possible clonal origin of malignant mesothelioma (MM) has not been investigated. Asbestos inhalation induces a chronic inflammatory response at sites of fiber deposition that may lead to malignant transformation after 30-50 years latency. As many mesothelial cells are simultaneously exposed to asbestos fibers and to asbestos-induced inflammation, it may be possible that more than one cell undergoes malignant transformation during the process that gives rise to MM, and result in a polyclonal malignancy. METHODS AND RESULTS: To investigate the clonality patterns of MM, we used the HUMARA (Human Androgen Receptor) assay to examine 16 biopsies from 14 women MM patients. Out of 16 samples, one was non-informative due to skewed Lyonization in its normal adjacent tissue. Fourteen out of the 15 informative samples revealed two electrophoretically distinct methylated HUMARA alleles, the Corrected Allele Ratio (CR) calculated on the allele peak areas indicating polyclonal origin MM. CONCLUSIONS: Our results show that MM originate as polyclonal tumors and suggest that the carcinogenic "field effect" of mineral fibers leads to several premalignant clones that give rise to these polyclonal malignancies.

RESUMO

OBJECTIVE: A predicted postoperative (ppo) forced expiratory volume in 1 second (FEV1%) or diffusing capacity of the lung for carbon monoxide (DLCO%) of <40% has traditionally been considered to convey a high risk of lobectomy owing to elevated postoperative morbidity and mortality. These recommendations, however, were largely derived from the pre-video-assisted thoracoscopic surgical (VATS) era. We hypothesized that VATS lobectomy would be associated with acceptable morbidity and mortality at ppoFEV1% and ppoDLCO% values < 40%. METHODS: PpoFEV1% and ppoDLCO% were calculated for patients undergoing open or VATS lobectomy for lung cancer in the Society of Thoracic Surgeons General Thoracic database from 2009 to 2011. Univariate comparisons, multivariate analyses, and 1:1 propensity matching were performed. RESULTS: A total of 13,376 patients underwent lobectomy (50.9% open, 49.1% VATS). A decreased ppoFEV1% and ppoDLCO% were each independent predictors for both cardiopulmonary complications and mortality in the open group (all P ≤ .008). In the VATS group, ppoFEV1% was an independent predictor of complications (P = .001) but not mortality (P = .77), and ppoDLCO% was an independent predictor of complications (P = .046) and mortality (P = .008). With decreasing ppoFEV1% or ppoDLCO%, complications and mortality increased at a greater rate in the open lobectomy than in a propensity-matched VATS group (n = 4215 each). For patients with ppoFEV1% < 40%, mortality was greater in the open (4.8%) than in the matched VATS group (0.7%, P = .003). Similar results were seen for ppoDLCO% < 40% (5.2% open, 2.0% VATS, P = .003). The rate of complications was significantly greater at ppoFEV1% < 40% in the open (21.9%) than in the matched VATS (12.8%, P = .005) group and similar results were seen with ppoDLCO% < 40% (14.9% open, 10.4% VATS, P = .016). CONCLUSIONS: VATS lobectomy can be performed with acceptable rates of morbidity and mortality in patients with reduced ppoFEV1% or ppoDLCO%.

RESUMO

INTRODUCTION: Nuclear EGFR (nEGFR) has been identified in various human tumor tissues, including cancers of the breast, ovary, oropharynx, and esophagus, and has predicted poor patient outcomes. We sought to determine if protein expression of nEGFR is prognostic in early stage non-small cell lung cancer (NSCLC). METHODS: Resected stages I and II NSCLC specimens were evaluated for nEGFR protein expression using immunohistochemistry (IHC). Cases with at least one replicate core containing ≥5% of tumor cells demonstrating strong dot-like nucleolar EGFR expression were scored as nEGFR positive. RESULTS: Twenty-three (26.1% of the population) of 88 resected specimens stained positively for nEGFR. Nuclear EGFR protein expression was associated with higher disease stage (45.5% of stage II vs. 14.5% of stage I; p = 0.023), histology (41.7% in squamous cell carcinoma vs. 17.1% in adenocarcinoma; p = 0.028), shorter progression-free survival (PFS) (median PFS 8.7 months [95% CI 5.1-10.7 mo] for nEGFR positive vs. 14.5 months [95% CI 9.5-17.4 mo] for nEGFR negative; hazard ratio (HR) of 1.89 [95% CI 1.15-3.10]; p = 0.011), and shorter overall survival (OS) (median OS 14.1 months [95% CI 10.3-22.7 mo] for nEGFR positive vs. 23.4 months [95% CI 20.1-29.4 mo] for nEGFR negative; HR of 1.83 [95% CI 1.12-2.99]; p = 0.014). CONCLUSIONS: Expression of nEGFR protein was associated with higher stage and squamous cell histology, and predicted shorter PFS and OS, in this patient cohort. Nuclear EGFR serves as a useful independent prognostic variable and as a potential therapeutic target in NSCLC.

RESUMO

BACKGROUND: BRCA1-associated protein 1 (BAP1) is a tumor suppressor gene located on chromosome 3p21. Germline BAP1 mutations have been recently associated with an increased risk of malignant mesothelioma, atypical melanocytic tumors and other neoplasms. To answer the question if different germline BAP1 mutations may predispose to a single syndrome with a wide phenotypic range or to distinct syndromes, we investigated the presence of melanocytic tumors in two unrelated families (L and W) with germline BAP1 mutations and increased risk of malignant mesothelioma. METHODS: Suspicious cutaneous lesions were clinically and pathologically characterized and compared to those present in other families carrying BAP1 mutations. We then conducted a meta-analysis of all the studies reporting BAP1-mutated families to survey cancer risk related to the germline BAP1 mutation (means were compared using t-test and proportions were compared with Pearson χ2 test or two-tailed Fisher's exact test). RESULTS: Melanocytic tumors: of the five members of the L family studied, four (80%) carried a germline BAP1 mutation (p.Gln684*) and also presented one or more atypical melanocytic tumors; of the seven members of W family studied, all carried a germline BAP1 mutation (p.Pro147fs*48) and four of them (57%) presented one or more atypical melanocytic tumors, that we propose to call "melanocytic BAP1-mutated atypical intradermal tumors" (MBAITs). Meta-analysis: 118 individuals from seven unrelated families were selected and divided into a BAP1-mutated cohort and a BAP1-non-mutated cohort. Malignant mesothelioma, uveal melanoma, cutaneous melanoma, and MBAITs prevalence was significantly higher in the BAP1-mutated cohort (p ≤ 0.001). CONCLUSIONS: Germline BAP1 mutations are associated with a novel cancer syndrome characterized by malignant mesothelioma, uveal melanoma, cutaneous melanoma and MBAITs, and possibly by other cancers. MBAITs provide physicians with a marker to identify individuals who may carry germline BAP1 mutations and thus are at high risk of developing associated cancers.

RESUMO

BACKGROUND: Many centers have adapted an Acuity Adaptable Cardiothoracic Unit (AACU) to fast track cardiac surgery patients, yet few data exist on the impact of such a unit on general thoracic surgery outcomes. We examined the effects of implementing an Acuity Adaptable Cardiothoracic Unit on patients undergoing major pulmonary resections. METHODS: We reviewed data from an IRB-approved, prospective thoracic surgery database for patients during the 3-y periods pre- and post-adoption of an Acuity Adaptable Cardiothoracic Unit. As surrogate endpoints to quality and cost, we examined length of stay, place of discharge, readmission rate, and 30-d mortality during these two time periods. RESULTS: A total of 488 patients underwent major pulmonary resections (416 lobectomies, 72 pneumonectomies) in this 6-y time period. Patients cared for in the AACU model had a shorter length of stay (LOS) compared with patients in a traditional ICU/general care model. The mean and median LOS for patients in the AACU model was 4.2 ± 0.3 d and 3 d, and for the traditional ICU/general care model these were 7.8 ± 1.2 d and 5 d, respectively (P < 0.001). Relative risk of readmission was 0.86 (95% CI = 0.45, 1.66, P = 0.392) and 30-d mortality was 0.49 (95% CI = 0.14, 1.68, P = 0.205) for patients in the AACU model compared with patients in the traditional ICU/general care unit. CONCLUSIONS: Implementation of an Acuity Adaptable Cardiothoracic Unit is associated with reduced length of hospital stay in patients undergoing major lung resections, without increased risk of readmission or 30-d mortality. Future studies will evaluate post-operative events unique to an AACU model.

RESUMO

BACKGROUND: No tool currently exists to rapidly allow surgeons to objectively quantify surgical risk in geriatric patients. The goal of our prospective study was to determine if individual questions extracted from validated screens for common geriatric syndromes would have predictive value for surgical risk in geriatric patients with thoracic neoplasms. METHODS: Patients ≥ 70 y old were recruited to participate in a prospective, IRB-approved study involving the preoperative administration of validated screening tests. Patients were given the geriatric depression scale (GDS), nutrition screening initiative nutritional health checklist (NSI NHC), mini mental status exam (MMSE), brief fatigue inventory (BFI), and assessed for activities of daily living (ADLs) and instrumental activities of daily living (IADLs). All patients enrolled in this study were scheduled for thoracic surgery. RESULTS: Patients who responded to having a dependency in the IADL "shopping" were more likely to have major complications and to be discharged to a non-home location than those without a dependency (P = 0.011, 0.003). Patients who answered "yes" to questions 1, 9, and 10 of the NSI NHC had a longer mean length of stay compared with patients who answered "no" (P = 0.039, 0.010, 0.031). Answering "yes" to GDS question 2 correlated with the incidence of major complications (r = 0.270 P = 0.037). Answering "yes" to GDS question 12 increased the likelihood of being discharged to a non-home location postoperatively (odds ratio = 11.64, 95% CI, 0.68-202.86, P = 0.047). CONCLUSIONS: Our data indicate that an abbreviated, rapid presurgical assessment can be developed for estimating operative risk, length of stay, and discharge destination in geriatric patients with thoracic malignancies using individual questions from previously validated screening tools.

RESUMO

PURPOSE: Accurate staging of esophageal cancer (ECA) is critical in determining appropriate therapy. Endoscopic ultrasound (EUS), computed tomography (CT) and positron emission tomography (PET) scanning can be used, but limited data exists regarding the use of combined PET/CT fusion imaging and EUS in ECA staging. The objective of this study is to evaluate the role of integrated PET/CT imaging and EUS in the staging of ECA. PROCEDURES: Identification of patients diagnosed with ECA from 2004 to 2007 that underwent staging PET/CT and EUS. Data regarding tumor detection, lymph node identification, presence of metastatic disease, and affect on patient management were collected and compared between PET/CT and EUS. RESULTS: Eighty-one patients (65 male, 16 female) were identified with mean age of 63.5 years who underwent EUS and PET/CT to stage known ECA. PET/CT identified the primary tumor in 74/81 (91.4%) of cases, compared to 81/81 (100%) with EUS. Locoregional adenopathy was seen by PET/CT in 29/81 (35.8%) of cases, compared to 49/81 (60.5%) by EUS (p = 0.0001). PET/CT identified celiac axis adenopathy in 8/81 (9.9%) of cases, compared to 11/81 (13.6%) with EUS (p = 0.5050). PET/CT identified 17/81 (21.0%) of patients with distant metastases who subsequently did not undergo attempt at curative surgical resection. CONCLUSIONS: In ECA, EUS is superior to PET/CT for T staging and in identifying locoregional nodes, while PET/CT provides M staging. EUS and integrated PET/CT appear to independently affect treatment decisions, indicating complimentary and necessary roles in the staging of ECA.

RESUMO

BACKGROUND: The presentation, management, and outcome of patients with primary cardiac sarcomas are not well defined. Furthermore, the role of adjuvant therapy has not been delineated in the management of primary cardiac sarcomas. METHODS: Patients with primary cardiac sarcoma and noncardiac sarcoma, diagnosed between 1988 and 2005, were identified in the Surveillance, Epidemiology, and End Results (SEER) database. Clinical characteristics and outcomes of primary cardiac sarcoma were defined and compared with the characteristics of noncardiac sarcomas. Univariate and multivariate methods were used to identify factors associated with primary cardiac sarcoma survival. RESULTS: Compared with noncardiac sarcomas, primary cardiac sarcomas were found to occur in a younger age group and were more likely to present with advanced disease. Primary cardiac sarcomas were ten times more likely to be vessel-derived (eg, angiosarcoma), comprising almost half of all cases. Median overall survival for cardiac sarcoma patients was 6 months whereas that for noncardiac sarcoma patients was significantly longer at 93 months (p < 0.001). Furthermore, cardiac sarcoma patients who underwent surgery had a median survival of 12 months whereas those who did not undergo surgery had a median survival of 1 month (p < 0.001). CONCLUSIONS: Cardiac sarcomas are a distinct, rare subset of soft tissue sarcomas with a poor prognosis. Surgery continues to be the central component of successful management. Future clinical efforts should be directed at developing approaches to permit safe radical excision and, potentially, developing effective adjuvant therapy.

RESUMO

Minimally invasive approaches increasingly are used to treat esophageal cancer and Barrett's esophagitis with high-grade dysplasia. The goals of a minimally invasive esophageal resection are to provide sound oncologic therapy while minimizing morbidity. This article describes the technique the authors use for laparoscopic-thoracoscopic esophagectomy. Comparison data are presented for alternative endoscopic therapy primarily used in candidates not suitable for surgery.

RESUMO

The role of left ventricular assist device (LVAD) in treatment options of congestive heart failure is becoming more important and the widespread application is imminent. There are, however, some serious complications associated with LVAD, which make patient management more challenging. We report a rare surgical case of asymptomatic diaphragmatic hernia, which was diagnosed 8.5 years after heart transplantation and LVAD explantation. A left mini (7 cm), muscle- and nerve-sparing thoracotomy was performed, and we found the splenic flexure of the colon herniated into the left pleural space through a small, circumferential defect of the diaphragm ( approximately 4 cm in diameter) created for the inflow cannula of LVAD. The hernia was reduced and the defect was repaired.

RESUMO

Acute esophageal necrosis (AEN) is an uncommon event. We report a case of an 84-year-old female with a giant paraesophageal hernia who presented with coffee ground emesis and on esophagogastroduodenoscopy (EGD) demonstrated findings consistent with acute esophageal necrosis and a giant paraesophageal hernia with normal-appearing gastric mucosa. She was managed conservatively with bowel rest, parenteral nutrition, and continuous intravenous proton pump inhibitor (PPI). After significant improvement in the gross appearance of her esophageal mucosa, surgery was performed to reduce her giant paraesophageal hernia. The patient's postoperative course was uneventful, and she was discharged home on postoperative day 6, tolerating a normal diet. The percutaneous endoscopic gastrostomy (PEG) tube was removed in clinic 2 months postoperatively.

RESUMO

BACKGROUND: EUS, CT, and positron emission tomography (PET) have all been used in the preoperative staging of esophageal cancer separately or in various combinations. OBJECTIVE: Our purpose was to determine the value and role of EUS when used in conjunction with CT and PET imaging in staging cancer of the esophagus and gastroesophageal junction. DESIGN: Retrospective single-center clinical trial. SETTING: Academic tertiary care center. PATIENTS: Data were examined for 56 patients who concomitantly underwent examination with EUS, CT, and PET in a multimodality staging program. MAIN OUTCOME MEASUREMENTS: EUS, CT, and PET were examined for their ability to detect the primary tumor, local tumor stage, locoregional adenopathy, and distant metastases. With use of surgical resection as baseline therapy, the frequency at which EUS, CT, and PET affected and changed management was examined. RESULTS: EUS is the only imaging test that identified all primary tumors and provided tumor staging. EUS identified a significantly greater number of patients (58.9%) with locoregional nodes than did CT (26.8%), P = .0006, or PET (37.5%), P = .02. CT identified 14.3% and PET identified 26.8% of patients with distant metastases. With CT alone, 15.2% of patients were not taken to surgery, whereas PET affected management by preventing surgery because of metastatic disease in 28.3% of patients. EUS changed management by guiding the need for neoadjuvant therapy in 34.8% of patients. LIMITATIONS: Retrospective study, nonblinded study, lack of pathologic reference standard. CONCLUSION: The primary strength of EUS in a multimodality staging strategy is in identifying patients with locally advanced disease and guiding the need for preoperative neoadjuvant therapy. EUS is not suited to determine resectability of esophageal cancer alone and thus is most effective when used in conjunction with other imaging tests such as CT and PET.

RESUMO

We report on the technical feasibility, dosimetric aspects, and daily image-guidance capability with megavoltage CT (MVCT) of stereotactic body radiotherapy (SBRT) using helical tomotherapy for medically inoperable T1/2 N0 M0 non-small cell lung cancer. Nine patients underwent treatment planning with 4D-CT in a double vacuum based immobilization system to minimize tumor motion and to define a lesion-specific 4D-motion envelope. Patients received 60 Gy in 5 fractions within 10 days to a PTV defined by a motion envelope plus a 6 mm expansion for microscopic extension and setup error using tomotherapy, with daily pretreatment MVCT image guidance. The primary endpoint was technical feasibility. Secondary endpoints were defining the acute and sub-acute toxicities and tumor response. Forty three of 45 fractions were successfully delivered, with an average delivery time of 22 minutes. MVCT provided excellent tumor visualization for daily image guidance. No significant tumor regression was observed on MVCT in any patient during therapy. Median mean normalized total doses were: tumor 117 Gy10; residual lung 9 Gy3. Maximum fraction-size equivalent dose values were: esophagus 5 Gy39; cord 7 Gy36. No patient experienced > or = grade 2 pulmonary toxicity. 3 complete, 4 partial and 2 stable responses were observed, with <3 months median follow-up. The mean tumor regression is 72%. SBRT using tomotherapy proved to be feasible, safe and free of major technical limitations or acute toxicities. Daily pretreatment MVCT imaging allows for precise daily tumor targeting with the patient in the actual treatment position, and therefore provides for precise image guidance.
