Summary
Regional perfusion with chemotherapy drugs, like nitrogen mustard, can reduce tumor size and pain. Isolating an area allows high drug concentration, protecting the patient from systemic toxicity.
Area of Science:
- Oncology
- Surgical Oncology
- Pharmacology
Background:
- Regional perfusion with cytostatic drugs was explored by Klopp et al. for pain and tumor reduction.
- Blocking venous return enhanced the efficacy of regional arterial blood flow injections.
- Recurrent malignant disease treatment spurred innovation in localized chemotherapy delivery.
Purpose of the Study:
- To introduce a novel concept for treating regionally recurrent malignant disease.
- To develop a method for isolating a body area from systemic circulation for chemotherapy.
- To achieve high chemotherapeutic concentrations locally while minimizing systemic toxicity.
Main Methods:
- Concept development involving cardiothoracic, plastic, and oncological surgeons.
- Utilizing an extracorporeal circuit with a heart-lung machine for isolated perfusion.
- Laboratory development of isolation perfusion techniques in canine models (hind limb, mid gut, liver).
Main Results:
- High concentrations of chemotherapeutic agents can be achieved in isolated perfusion circuits.
- The dosage of nitrogen mustard tolerated in isolated hind limb perfusion was equivalent to a single systemic dose.
- The technique aims to maximize tumor exposure while protecting the patient from systemic side effects.
Conclusions:
- Isolated regional perfusion allows for targeted, high-dose chemotherapy delivery.
- This method offers a potential strategy to improve outcomes for regionally recurrent cancers.
- Further research and development of isolation perfusion techniques are warranted.

696
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

01:15Diabetes: Symptoms, Diagnosis, and Complications
2.1K
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

01:20Arteries of Lower Limbs
4.3K
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

01:15Veins of Lower Limbs
2.3K
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...
