Brief Summary

This study will monitor and evaluate patient and personnel safety and toxicity during the implementation and evaluation of Pressurized IntraThoracic Aerosol Chemotherapy (PITAC) directed treatment. Furthermore, this study will focus on Quality of Life questionnaires, LENT score, and evaluate pain and breathlessness using af visual analogue scales (VAS).

Detailed Description

This is a safety and feasibility study of repeated (minimum two procedures) PITAC directed treatments, and the primary outcome is the number of patients with medical adverse events (AEs) according to the Common Terminology Criteria for Adverse Events (CTCAE) and/or surgical complications according to the Clavien-Dindo classification. This study will include consecutive MPE patients until 20 patients have completed at least two PITAC´s. The PITAC directed treatment will be performed in 4 week intervals. Bedside ultrasound, VAS-pain and VAS-breathlessness, and Quality of Life questionnaires will be performed at baseline, one month follow-up and three months follow-up.

Patients with MPE who are eligible for surgery are identified during the multidisciplinary tumor (MDT) conference at the Department of Surgery, Odense University Hospital (OUH), and included based on predefined in- and exclusion criteria. Patients with MPE from non-colorectal or -appendix cancer will be treated with a combination of cisplatin and doxorubicin. Patients with MPE from colorectal or appendix cancer will be treated with oxaliplatin.

In brief, The PITAC procedure is the application of aerosolized chemotherapy into the pleural cavity using thoracoscopy. PITAC is performed in the prone or lateral position. A double lumen endotracheal tube is used to allow exclusion of the ipsilateral lung, but this is not (always) necessary with the patient in the prone position. The first trocar is placed guided by ultrasound, and after safe positioning a second trocar can be inserted guided by video thoracoscopy. The chemotherapy is applied to the pleural cavity through a nebulizer inserted through one of the trocars and linked to a high-pressure injector. After five minutes the chemotherapy has been delivered to the pleural cavity, and after an additional 30 minutes of simple diffusion, the intrathoracic air saturated with chemotherapy is evacuated through a series of filters.

The patients are monitored for a minimum of one day and will after each PITAC directed treatment be screened for adverse events.

• Myocardial insufficiency, defined as NYHA class > 2

• Impaired liver function defined as bilirubin ≥1.5

• Fertility, pregnancy and lactation: Female subjects will be considered of non-reproductive potential if they are either a, b or c:

Arm && Interventions

Group	Intervention	Description
PITAC	PITAC	Malignant Pleural Effusion (MPE) from colorectal or appendix cancer will be treated with Pressurized IntraThoracic Aerosol Chemotherapy (PITAC) using oxaliplatin 92 mg/m2 in 150 ml dextrose. MPE from non-colorectal or -appendix cancer will be treated with PITAC using cisplatin 10.5 mg/m2 in 150 ml saline and 2.1 mg/m2 in 50 ml saline. PITAC is performed with a intrapleural pressure of 12 mmHg and the aerosolised chemotherapy will be nebulized at a maximum pressure of 300 PSI and a flow-rate of 0.5-1.8 ml/min. The PITAC directed treatment will be planned with 4 week intervals and patients may receive bi-directional systemic chemotherapy simultaneously.
