Five Years PLEURATUMOR Register of the German Society of Thoracic Surgery

Abstract

Since 01.01.2015, the nationwide "PLEURATUMOR Register of the German Society of Thoracic Surgery (DGT)" has documented the most relevant parameters of patients with primary and secondary malignant pleural diseases receiving thoracic surgery in Germany. This online database is intended to record both primary and recurrent diseases. In particular, the registry focuses on the documentation of patients with pleural carcinosis, malignant pleural mesothelioma and tumours of the thymus with pleural dissemination. A structured evaluation of all patients documented up to and including December 2019 was carried out. At this time, 33 departments participated in the PLEURATUMOR Register and 670 patients have been recorded. Of these patients, 522 data sets were complete and 516 patients received surgical treatment. Most patients were documented in 2017 (n = 135; 26.2%), and in 2019 (n = 72; 14%). With 317 listed patients (61.4%), pleural carcinosis was the most frequently reported pleural tumour, followed by malignant pleural mesothelioma (n = 175; 33.9%) and thymoma/thymic carcinoma with pleural metastases (n = 11; 2.1%). The majority of patients (n = 499; 96.7%) were treated because of an initial manifestation. The most frequently documented procedure was VATS-talcum pleurodesis (n = 204; 39.5%). In 69 patients (13.4%) hyperthermic intrathoracic chemotherapy was performed after cytoreductive surgery. Postoperative complications occurred in 107 patients (20.7%); in 35 cases (6.8%) surgical revision was necessary. The overall 30-day mortality was 8.3% (n = 43). Due to the consistent data entry of the participating clinics, a representative dataset of pleural tumour diseases could be recorded. In the future, we hope for consistent continuation of data entry and the initiation of register-based studies.
