Lymphadenectomy (Lymph Node Dissection) in Delhi, India

A lymphadenectomy, also known as a lymph node dissection, is a surgical procedure to remove one or more lymph nodes. This procedure is performed to diagnose, stage, and treat various types of cancer that may have spread from their original site to nearby lymph nodes.

There are two main types of lymphadenectomy:

• Regional Lymphadenectomy: This involves the removal of lymph nodes in a specific area near the tumour. For example, in breast cancer surgery, a surgeon might perform an axillary lymph node dissection to remove lymph nodes from the armpit.
• Radical Lymphadenectomy: This is a more extensive procedure where a larger number of lymph nodes are removed, often from multiple regions. It's typically used when cancer is suspected of having spread more widely.

After the lymph nodes are removed, a pathologist examines them under a microscope to check for the presence of cancer cells. This information is crucial for determining the stage of the cancer and for guiding the patient's treatment plan.

At Max Hospitals, we frequently perform lymphadenectomy as a critical part of a comprehensive treatment plan for various types of cancer. This procedure serves a dual purpose: it helps us accurately diagnose and stage the cancer by determining if it has spread to the lymph nodes, and it acts as a treatment by removing affected lymph nodes to help prevent further spread. Here are some of the cancers for which lymphadenectomy is a common and effective procedure:

• Breast Cancer: A key part of treating breast cancer involves a lymph node dissection in the armpit (axillary lymph node dissection) to check for and remove cancer cells that may have spread from the breast tissue.
• Melanoma: For advanced melanomas, we often perform a lymph node dissection in the area closest to the skin lesion to check if the cancer has spread and to remove any affected nodes.
• Head and Neck Cancer: Lymphadenectomy is crucial for managing cancers in this region, as it helps determine the extent of the disease and removes nodes to prevent it from moving to other parts of the body.
• Thyroid Cancer: When treating thyroid cancer, especially if it's aggressive, we may remove lymph nodes in the neck to ensure all cancerous tissue is eliminated.
• Lung Cancer: Lymph node dissection in the chest is a standard procedure for lung cancer to assess the spread and remove any cancerous nodes, which is vital for staging and treatment planning.
• Gastrointestinal Cancers: For cancers of the stomach and colon, removing nearby lymph nodes is essential for both staging the disease and ensuring a more complete surgical removal of the cancer.

A lymphadenectomy, like any surgery, comes with certain risks and possible side effects. These can depend on how many lymph nodes are removed and from which part of the body.

Common Risks and Side Effects

• Pain and swelling around the surgical site
• Infection at the incision site
• Bleeding or blood clots (rare but possible)
• Fluid build-up (seroma) where lymph nodes were removed
• Nerve injury (can cause numbness, tingling, or weakness in the affected area)

Long-term Risks

• Lymphedema: swelling in the arm, leg, or other area due to lymph fluid build-up (especially common after removal of nodes in the armpit or groin)
• Reduced mobility or stiffness near the surgical area
• Increased risk of infection in the affected limb (because the immune defence in that region is lowered)
• Scarring

Undergoing a lymphadenectomy can feel overwhelming, but understanding what to expect at each phase helps patients and their families feel more prepared and confident. The journey typically involves three key phases: preparation before the procedure, the day of surgery, and post-operative recovery.

Preoperative Preparation

• Medical Evaluation: A thorough medical assessment is performed to ensure the patient is in the best possible health for surgery. This may include blood tests, imaging studies like CT or MRI scans, and a physical exam.
• Medication Adjustments: Patients are given specific guidance on which medications, particularly blood thinners, may need to be stopped or adjusted before the procedure to minimize the risk of bleeding.
• Practical Planning: Instructions are given for fasting before surgery and arranging for post-operative support at home, which is crucial for a smooth recovery.

On the Day of the Procedure

• Hospital Admission: The patient is admitted to the hospital, and a final review of their medical information is conducted.
• Anesthesia: The anesthesiology team administers general anesthesia to ensure the patient is comfortable and pain-free throughout the procedure.
• Surgical Process: The surgeon carefully performs the lymphadenectomy, removing the targeted lymph nodes. The specific technique and incision size depend on the location and number of nodes being removed.
• Immediate Recovery: After surgery, the patient is moved to a recovery room where they are closely monitored as the anesthesia wears off.

Post-Operative Care and Recovery

• Pain Management: Mild to moderate pain or discomfort is normal and is managed with prescribed medication to ensure the patient is comfortable during the initial healing period.
• Drainage and Swelling: A surgical drain is placed to help remove fluid and reduce swelling in the surgical area. This is removed once fluid collection has subsided.
• Activity Restrictions: The patient is advised to avoid strenuous activities and heavy lifting for a period of time to allow for proper healing.
• Lymphedema Prevention: In some cases, a lymphadenectomy can lead to lymphedema (swelling). The patient is given instructions on how to prevent this, which may include exercises, massage, and wearing a compression garment.
• Follow-up Visits: Regular appointments are scheduled with the surgeon to monitor the patient's recovery, remove any sutures, and discuss the pathology report of the removed lymph nodes.

What exactly are lymph nodes?

Lymph nodes are small, bean-shaped glands that are part of your immune system. They help filter waste and fluid from your body and contain immune cells that help fight off infections and diseases, including cancer.

Why is a lymphadenectomy necessary for cancer treatment?

The procedure serves a dual purpose. It helps doctors determine if cancer has spread to the lymph nodes, which is crucial for accurate staging. It is also a treatment, as removing the affected lymph nodes can help prevent the cancer from spreading to other parts of the body.

Is a lymphadenectomy the only treatment I will need?

Often, a lymphadenectomy is just one part of a comprehensive cancer treatment plan. It may be combined with other therapies, such as chemotherapy, radiation, or targeted therapy, depending on the type and stage of your cancer.

How long does the surgery take?

The duration of the surgery varies widely depending on the number of lymph nodes being removed and their location. Your surgeon will give you a more specific estimate during your consultation.

How long will I have to stay in the hospital?

Hospital stays can range from a same-day discharge to a few days. The length of your stay will depend on the extent of the surgery and how quickly you recover.

Will I have a scar?

Yes, a lymphadenectomy is a surgical procedure that requires an incision, so a scar is expected. The size and appearance of the scar will depend on the location and type of surgery performed.

How painful is the recovery?

Some pain and discomfort are normal after surgery. Your healthcare team will provide you with a pain management plan, including medication, to ensure you are comfortable throughout your recovery.

When can I return to my normal activities?

This varies by person and the type of surgery. While you will be encouraged to walk soon after the procedure, strenuous activities and heavy lifting should be avoided for several weeks to allow your body to heal properly.

What is lymphedema, and how can I prevent it?

Lymphedema is a type of swelling that can occur if a significant number of lymph nodes are removed. To help prevent it, your care team may recommend specific exercises, physical therapy, massage, or wearing a compression garment.

What is a sentinel lymph node biopsy?

A sentinel lymph node biopsy is a less extensive procedure where only the first one or two lymph nodes to which the cancer is likely to spread (the "sentinel" nodes) are removed and examined. If they are free of cancer, no further lymph nodes may need to be removed.

How long does it take to get the pathology report?

The pathology report, which confirms whether cancer cells were found in the removed lymph nodes, can take a few days to a week. Your doctor will discuss the results with you as soon as they are available.

Can a lymphadenectomy affect my immunity?

Removing lymph nodes may have a temporary impact on your body’s ability to fight certain infections. However, your body has many lymph nodes throughout, so the impact is generally not significant.

Are there any dietary restrictions after surgery?

While there are no specific dietary restrictions related to the procedure itself, a healthy diet is crucial for promoting healing and overall well-being. Your doctor may provide specific nutritional advice based on your needs.

What if I feel a lump or swelling after surgery?

You should immediately contact your doctor. It's important to have any new swelling or lumps checked out to ensure they are a normal part of the healing process and not a sign of a complication.

Is a lymphadenectomy covered by insurance?

Yes, since lymphadenectomy is a medically necessary procedure for cancer treatment, it is typically covered by most health insurance plans. It's always a good idea to contact your insurance provider directly to confirm your specific coverage details.
