RESUMO

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspirations (EBUS-TBNAs) are well established for staging lung cancer. A growing number of publications report on lymphoma diagnosis via EBUS-TBNA-acquired cytology; however current guidelines recommend histologic diagnosis. Research on the value of EBUS-TBNA-acquired cytology versus surgical-acquired histology in the diagnosis of lymphoma is lacking. METHODS: We conducted a retrospective review of patients with mediastinal lymphoma diagnosed between 2010 and 2016. Mediastinal lymphadenopathy was accessible through both EBUS-TBNAs and surgical procedures. All data were extracted from our clinic's medical database and analyzed. RESULTS: Fifty-one patients newly diagnosed with lymphoma in the mediastinum were identified (median age, 43.5 years; mean age, 48.6 ± 20.6 years). A minimally invasive procedure was performed as a first diagnostic step in 29 patients, whereas surgical biopsy was performed in the remaining 22. The time to final diagnosis was significantly longer if a minimally invasive procedure was performed first compared with a surgical procedure (mean, 44 days [median, 38 days] vs 16 days [median, 8 days]; p < 0.030). The number of procedures to obtain a final diagnosis ranged from one to five (median, 2 procedures per patient) in the EBUS-TBNA group. This was significantly higher than that in the surgical group (median, 1 procedure per patient; p < 0.00005). CONCLUSIONS: We demonstrate that surgical biopsies are safe and well tolerated for lymphoproliferative disease diagnosis and lead to a final diagnosis in the shortest possible time. Unnecessary procedures were significantly reduced if a surgical biopsy was performed as the first step.

RESUMO

BACKGROUND: Pulmonary metastasectomy is an established treatment modality for patients with soft as well as bone tissue sarcomas. Aim of this study is to describe the Essen experience in the surgical management of patients with pulmonary sarcoma metastases. METHODS: This is a retrospective single center analysis of perioperative outcome of patients undergoing pulmonary metastasectomy for sarcoma metastases from 1997-2017 and a summary of published papers on this topic. RESULTS: During the observation period 327 patients (49.23% female) underwent pulmonary metastasectomy for metastases of extrathoracic sarcomas in curative intent. The number of resected metastases was 1-3 in 283 cases (86.54%), 4-9 in 31 cases (9.48%) and 10 or more lesions in 14 cases (4.28%). Wedge resections or precision excisions with laser or electrocautery were performed in 278 cases (85.02%), anatomical segmental resections in 16 patients (4.89%) and lobectomies in 33 patients (10.09%). Bilateral procedures were performed in 98 cases (29.96%). Lymphadenectomy was performed in 122 patients. Positive lymph nodes were found only in 6 cases. All of these cases were patients with soft tissue sarcoma as primary tumor. Preoperative neoadjuvant treatment was performed in 79 patients (24.15%) with chemotherapy, in 54 patients (16.51%) with radiochemotherapy and in 10 patients (3.05%) with radiotherapy. Major postoperative complications were observed in 2.75% of all patients. Thirty-day mortality was 0%. CONCLUSIONS: Pulmonary metastasectomy in sarcoma patients is a feasible and safe treatment strategy even in patients with bilateral metastases and multiple lesions. Thoracic lymph node metastases are rare and did not influence survival in our cohort.

RESUMO

BACKGROUND: Operative risk scoring algorithms identify patients with severe AS for transcatheter valve implantation in whom the anticipated operative mortality for conventional surgery would be considered prohibitive. We compared the three risk scores EuroScore 1 (LES), society of thoracic surgeons' (STS) score and ACEF (age-creatinine-ejection fraction score) to the readjusted EuroScore 2 recently presented. METHODS: We reviewed all consecutive patients receiving either isolated conventional aortic valve replacement (cAVR) or transapical aortic valve implantation (TA-TAVI) in a two-year period (n = 206). 30-days mortality was considered as primary endpoint. RESULTS: TA-TAVI was performed in 76 patients, isolated cAVR in 130 patients. Overall mortality was 4.4% (TA-TAVI: 7.9%; cAVR: 2.3%). EuroScore 2 showed a good estimation for the entire population as well as within the subgroups: 4,02 ± 5,36% (TA-TAVI: 6.16 ± 7.14%, cAVR: 2.77 ± 3.42%). Predicted mortalities as assessed by LES were largely overestimated (TA-TAVI: 27.4 ± 20.9% cAVR: 10.6 ± 10.6%, sensitivity: 0.89, specificity: 0.71). STS predicted mortality was 6.3 ± 4.4% for TA-TAVI patients as to 3.2 ± 3.1% for cAVR patients (sens.: 0.22, spec.: 0.96) and ACEF predicted a mortality of 1.16 ± 0.36% for cAVR and 1.58 ± 0.59% for TA-TAVI patients (sens.: 0.78, spec.: 0.89). CONCLUSION: The newly refined EuroScore 2 showed a good correlation within the studied population. For the individual patient, new cut-offs will have to be defined to triage patients for TAVI procedure. A drawback for complex score systems such as EuroScore and STS is the lack of recalibration to smaller populations as encountered in even large single centers.
