Chemo Port for Lung Cancer

As part of your lung cancer treatment plan, your medical team may recommend having a chemotherapy port (chemo port) implanted. A chemo port is a device that allows medications to be delivered directly into your vein without the need for repeated needle sticks. While this may be an unfamiliar procedure, understanding how a chemo port works can help you feel more informed and empowered when discussing your treatment options with your healthcare providers.

A chemo port is a small disc made of plastic or metal that sits just under the skin, typically on the chest. It has a soft, hollow tube called a catheter that connects the port to a large vein, usually near the heart. The port acts as an access point, allowing medications, fluids, blood products, and even contrast dyes for imaging to be easily administered directly into the bloodstream via the catheter.

Using a chemo port can make the process of receiving chemotherapy and other intravenous (IV) treatments more comfortable by eliminating the need for frequent needle sticks into smaller veins in your arms. With proper care, chemo ports are designed to remain in place for extended treatment periods.

In addition to chemotherapy delivery, chemo ports can be used for:

• Drawing blood samples
• Administering other IV medications or fluids
• Providing blood products like platelets or plasma
• Injecting contrast dyes for radiographic imaging procedures

Chemo ports are available in plastic or metal constructions. For lung cancer patients who require regular imaging tests like CT or MRI scans, the implanted ports are designed to be safe for use with these procedures. Some common types include:

• Single lumen port: Has one entry point into the catheter.
• Double lumen port: Contains two separate entries into the catheter.
• Power-injectable port: Allows for higher pressure injections of fluids or contrast.

Chemo ports are produced by various manufacturers and may be marketed under different brand names, such as Bardport®, Port-A-Cath®, PowerPort®, SlimPort®, X-Port™, and others.

The implantation of a chemo port is a minimally invasive procedure, typically performed by a surgeon or an interventional radiologist who specializes in image-guided procedures. Local anesthesia and moderate sedation are administered to ensure your comfort during the process, which may make you feel drowsy. It is advisable to have someone accompany you for transportation following the procedure.

During implantation, a small incision is made just under the collarbone to create an entry point for the port. The attached catheter is then carefully inserted and threaded through a vein, commonly the jugular or subclavian vein, near the heart. Finally, the port is positioned under the skin, and the incision is closed with stitches or surgical adhesive.

The implantation site will heal over time, and any stitches used will dissolve, leaving a minimal scar. Scarring is typically minimal and should not be a significant concern.

When it is time for chemotherapy or other treatments, your healthcare team will first clean and sterilize the area of skin over your chemo port. A special huber needle will then be inserted through your skin and into the port. You may feel a slight pinching sensation, but the process should not be painful.

A thin, flexible tube attaches to the huber needle, creating an easy pathway for administering medications, drawing blood samples, or injecting contrast dyes. A sterile dressing will be applied over the needle site to keep it clean and secure throughout your treatment session. After each use, the tubing will be flushed with a sterile solution to maintain patency.

Proper care of your chemo port is essential to prevent infections, though serious infections are relatively rare. When not in use, the port will be flushed periodically with a sterile saline solution, which may contain an antibiotic. This flushing, performed by your nurse under sterile conditions, keeps the port clear and reduces infection risk.

Watch for any signs of potential infection like redness, swelling, warmth, or pain at the port site and alert your cancer care team promptly if you have concerns. Clotting within the catheter, known as thrombosis, is another possible complication. To help prevent this, the saline flush solution often contains a small amount of the anti-clotting medication heparin. In cases of significant clotting, the port may need to be surgically replaced.

If you are undergoing lung cancer treatment, having a chemo port placed can be an important part of your care plan. This innovative device is designed to make medication delivery more efficient, comfortable, and accessible for patients receiving chemotherapy. In addition to chemotherapy administration, the port allows easy blood draws and injections required for imaging procedures.

While having a port protruding slightly under your skin may seem unusual initially, it is a temporary aspect of your treatment intended to improve your overall experience. Be sure to follow all instructions from your care team for proper port care and maintenance.
