A percutaneous approach was developed for the performance of regional isolation-perfusion, a surgical chemotherapeutic procedure for the intraarterial treatment of neoplasms. This technique was compared with percutaneous transcatheter arterial occlusion-infusion concerning local and systemic drug levels. Floxuridine (FUDR) was administered into a femoral artery of adult mongrel dogs, first by arterial occlusion-infusion, and 4 weeks later by regional isolation-perfusion of the opposite hind limb. Local and systemic plasma samples and local muscle specimens were collected for determination of FUDR levels. Results indicated not only that regional isolation-perfusion could be accomplished percutaneously, using balloon catheters, but also that the technique produced significantly greater local tissue FUDR levels (P less than 0.05) than those achieved with arterial occlusion-infusion.

Background: Innovative systemic treatments and loco-regional chemotherapy by hypoxic pelvic perfusion (HPP) have been proposed for unresectable recurrent rectal cancer (URRC). Regorafenib and trifluridine-tipiracil reported significantly increased PFS 1.9-2.

Isolated thoracic perfusion with chemofiltration for progressive malignant pleural mesothelioma.

Introduction: Therapy of malignant pleural mesothelioma and especially the adequate role of surgery in this context remain the subject of controversial discussions. Radical surgery in particular, which is associated with substantial morbidity, failed to translate into a definite survival advantage. We report on interim results of an ongoing Phase II study of regional chemotherapy in terms of isolated thoracic perfusion with chemofiltration (ITP-F).

The development of effective treatment strategies to provide durable control of isolated diffuse metastases to the liver is a major challenge in clinical oncology. The number of patients afflicted annually with isolated liver metastases is considerable; of the 156,000 patients diagnosed with colorectal cancer in 2009, it is estimated that up to 40,000 will develop liver metastases as the sole or dominant site of disease progression and of whom only 10% to 20% will have tumors amenable to resection. Patients with neuroendocrine cancers and ocular melanoma will frequently develop isolated and diffuse liver metastases as the dominant mode of tumor metastasis and, although less frequent, patients with other types of cancers such as cutaneous melanoma or breast cancer can occasionally develop isolated diffuse metastases to the liver.

Background: Patients with ocular melanoma liver metastases have a poor prognosis, treatment options are limited, and median survival is less than 1 year. In this study, we characterized the early molecular changes that occur in tumors immediately after vascular isolation perfusion with melphalan with hyperthermia in patients with hepatic metastases from ocular melanoma.

Methods: Patients underwent treatment on a clinical trial using a 60-min hyperthermic isolated hepatic perfusion (IHP) with melphalan.

Thousands of patients die annually from unresectable metastatic or primary hepatic cancers confined to liver. Isolated hepatic perfusion (IHP) is a regional treatment strategy in which the vascular supply to the liver is isolated and perfused with a therapeutic regimen using an extracorporeal circuit consisting of a reservoir, heat exchanger, and oxygenator. Drug doses that would cause severe toxicities if delivered systemically can be confined to the liver by isolated hepatic perfusion, resulting in the ability to intensify treatment to the cancer-burdened region of the body.
