Multimodal Treatment of Pleural Mesothelioma with Cytoreductive Surgery and Hyperthermic Intrathoracic Chemotherapy: Impact of Additive Chemotherapy.

Cytoreductive surgery (CRS) combined with hyperthermic intrathoracic chemoperfusion (HITOC) is a promising treatment strategy for pleural mesothelioma (PM). The aim of this study was to evaluate the impacts of this multimodal approach in combination with systemic treatment on disease-free survival (DFS) and overall survival (OS). In this retrospective multicenter study, clinical data from patients after CRS and HITOC for PM at four high-volume thoracic surgery departments in Germany were analyzed.

Outcome after cytoreductive surgery combined with hyperthermic intrathoracic chemotherapy in patients with secondary pleural metastases.

Background: The role of cytoreductive surgery combined with hyperthermic intrathoracic chemotherapy (CRS+HITOC) for patients with secondary pleural metastases has scarcely been investigated.

Patients And Methods: We conducted a retrospective, multicentre study investigating the outcome of CRS+HITOC for 31 patients with pleural metastases from different primary tumours in four high-volume departments of thoracic surgery in Germany. The primary endpoint was overall survival (OS).

The Excretion of Cisplatin after Hyperthermic Intrathoracic Chemotherapy.

Hyperthermic intrathoracic chemotherapy (HITOC) is an additional intraoperative treatment option within the multimodality therapy of pleural malignancies. A chemotherapy perfusion with high-dose cisplatin is performed over a period of 60 min after surgical cytoreduction to improve local tumour control through the eradication of residual tumour cells. Although HITOC is increasingly used, there is only little scientific evidence about the necessary safety measures after HITOC.

Intraoperative Contrast-Enhanced Ultrasonography (Io-CEUS) in Minimally Invasive Thoracic Surgery for Characterization of Pulmonary Tumours: A Clinical Feasibility Study.

Background: The intraoperative detection of solitary pulmonary nodules (SPNs) continues to be a major challenge, especially in minimally invasive video-assisted thoracic surgery (VATS). The location, size, and intraoperative frozen section result of SPNs are decisive regarding the extent of lung resection. This feasibility study investigates the technical applicability of intraoperative contrast-enhanced ultrasonography (Io-CEUS) in minimally invasive thoracic surgery.

Surgical cytoreduction and hyperthermic intrathoracic chemotherapy for thymic tumours with pleural spread is effective on survival: results from the multicentre German hyperthermic intrathoracic chemotherapy study.

Objectives: Cytoreductive surgery and hyperthermic intrathoracic chemotherapy (HITOC) is effective on survival for patients with pleural metastatic thymic tumours.

Methods: Multicentre, retrospective analysis of patients with stage IVa thymic tumours treated with surgical resection and HITOC. Primary end point was overall survival, secondary end points were recurrence-/progression-free survival and morbidity/mortality.

[Mediastinal tumors : Diagnosis and treatment of the most common tumor entities].

The mediastinum is defined as the space formed ventrally by the sternum, dorsally by the spine, and laterally by the mediastinal pleura. A mediastinal mass is frequently an incidental finding. The wide spectrum of underlying diseases and the anatomic proximity to central structures makes diagnosis and treatment challenging.

Postoperative outcome after palliative treatment of malignant pleural effusion.

Background: The objective of this nationwide, registry-based study was to compare the two most frequently used procedures for the palliative treatment of a malignant pleural effusion (MPE) and to evaluate differentiated indications for these two procedures.

Methods: This was a retrospective observational study based on data of the "PLEURATUMOR" registry of the German Society for Thoracic Surgery. Patients who were documented in the period from January 2015 to November 2021 and had video-assisted thoracic surgery (VATS) talc pleurodesis or implantation of an indwelling pleural catheter (IPC) were included.

The Treatment of Malignant Pleural Effusion With Permanent Indwelling Pleural Catheters.

Background: 40 000 to 60 000 people develop malignant pleural effusion (MPE) in Germany each year. The most common causes are lung cancer and breast cancer. Patients with pleural carcinomatosis have a median survival time of four months.

Hyperthermic Intrathoracic Chemotherapy (HITOC) after Cytoreductive Surgery for Pleural Malignancies-A Retrospective, Multicentre Study.

In the context of quality assurance, the objectives were to describe the surgical treatment and postoperative morbidity (particularly renal insufficiency). A retrospective, multicentre study of patients who underwent cytoreductive surgery (CRS) with cisplatin-based HITOC was performed. The study was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation (GZ: RI 2905/3-1)).

Evaluation of Surgical Therapy in Advanced Thymic Tumors.

A complete resection of thymic tumors is known to be the most important prognostic factor, but it is often difficult to perform, especially in advanced stages. In this study, 73 patients with advanced thymic tumors of UICC stages III and IV who underwent radical resection were examined retrospectively. The primary endpoint was defined as the postoperative resection status.

Hyperthermic intrathoracic chemotherapy (HITHOC): narrative review of the current literature, recommendations and future studies.

Although the method of hyperthermic intrathoracic chemotherapy (HITHOC) after cytoreductive surgery is known for more than 20 years now, the interest of the scientific community has been growing especially in recent years with annually increasing numbers of publications. The feasibility and safety of HITHOC has already been demonstrated. The primary objective now is to reach a consent about the optimal implementation and standardization of the procedure.

Assessment of concentration and penetration depth of cisplatin in human lung tissue after decortication and hyperthermic exposure.

Background: Hyperthermic perfusion of the pleural cavity with cisplatin after pleurectomy/decortication is an additional therapeutic option to reduce local relapse of malignant pleural tumours. Although there are data on the clinical effect, only little is known about the local impact on human lung tissue by cisplatin. The objective of this experimental study is to evaluate both the concentration and the penetration depth of cisplatin in human lung tissue after normothermic and hyperthermic exposure under ex-vivo-in-vitro conditions.

Exposure to cisplatin in the operating room during hyperthermic intrathoracic chemotherapy.

Purpose: Hyperthermic intrathoracic chemotherapy (HITOC) is an additive, intraoperative treatment for selected malignant pleural tumors. To improve local tumor control, the thoracic cavity is perfused with a cisplatin-containing solution after surgical cytoreduction. Since cisplatin is probably carcinogenic to humans, potential contamination of surfaces and pathways of exposure should be systematically investigated to enable risk assessments for medical staff and thus derive specific recommendations for occupational safety.

Video-assisted pulmonary metastectomy is equivalent to thoracotomy regarding resection status and survival.

Background: Surgical resection of pulmonary metastases leads to prolonged survival if strictly indicated. Usually, thoracotomy with manual palpation of the entire lung with lymph node dissection or sampling is performed. The aim of this study was to evaluate the role of video-assisted thoracoscopic surgery (VATS) in pulmonary metastectomy with curative intent.

Classification and staging of thymoma.

The appropriate therapy and prognosis of patients with thymic malignancies is decisively influenced by the local extent and dissemination of the tumor. For this reason, a staging system that reflects these factors is essential. Mainly the Masaoka-Koga classification, which was introduced in 1994, has been applied for this purpose.

[Extended Resection of Locally Advanced Thymic Tumours in Stage III].

In the treatment of locally advanced thymic tumours, specific diagnostic testing is required, with a multimodal therapeutic approach consisting of surgery, radio- and/or chemotherapy. The complete resection of the tumour represents the most important prognostic factor with regard to recurrence-free and long-term survival. Local invasive growth of malignant thymic tumours into neighbouring mediastinal structures is classified as Masaoka-Koga stage III.

Protocol of a retrospective, multicentre observational study on hyperthermic intrathoracic chemotherapy in Germany.

Introduction: Objective of the 'German hyperthermic intrathoracic chemotherapy (HITOC) study' is to evaluate the HITOC as additional treatment after surgical cytoreduction for malignant pleural tumours. Even though HITOC is applied with increasing frequency, there is no standardised therapy protocol concerning the technique of HITOC, the selection as well as dosage of chemotherapeutic agents and perioperative management in order to provide a safe and comparable, standardised treatment regime.

Methods And Analysis: This trial is a retrospective, multicentre observational study, which is funded by the German Research Foundation.

[Five Years PLEURATUMOR Register of the German Society of Thoracic Surgery].

Background: 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.

Surgical Cytoreduction and HITOC for Thymic Malignancies with Pleural Dissemination.

Background: Objective of this study was to assess postoperative morbidity and mortality as well as recurrence-free and overall survival in patients with thymic malignancies and pleural dissemination undergoing surgical cytoreduction and hyperthermic intrathoracic chemotherapy (HITOC).

Methods: Retrospective study between September 2008 and December 2017 with follow-up analysis in May 2018.

Adequate nephroprotection reduces renal complications after hyperthermic intrathoracic chemotherapy.

Background And Objectives: Hyperthermic intrathoracic chemotherapy (HITOC) is used for the treatment of malignant pleural tumors. Although HITOC proved to be safe, postoperative renal failure due to nephrotoxicity of intrapleural cisplatin remains a concern.

Methods: This single-center study was performed retrospectively in patients who underwent pleural tumor resection and HITOC between September 2008 and December 2018.

Incidental thoracic findings in computed tomography scans before transcatheter aortic valve implantation.

Objectives: Preoperative computed tomography (CT) scans for transcatheter aortic valve implantation (TAVI) are used routinely. In elderly high-risk patients, incidental radiographic findings are frequently reported. The aim of this study was to investigate the impact of auxiliary findings on the patients' mid-term survival, which might affect the treatment strategy.
