Mesencephalotomy for intractable pain due to malignant disease

Area of Science:

• Neurosurgery
• Oncology
• Pain Management

Background:

• Intractable pain is a significant challenge in patients with advanced malignant disease.
• Cancer-related pain often affects the head, neck, and upper trunk.
• Limited effective treatment options exist for severe, refractory cancer pain.

Purpose of the Study:

• To evaluate the efficacy of mesencephalotomy in managing intractable pain in cancer patients.
• To assess the suitability of mesencephalotomy for pain in the head, neck, and upper trunk regions.
• To determine the need for bilateral procedures in cases of bilateral pain.

Main Methods:

• Performed 40 mesencephalotomies on 38 patients with intractable pain due to malignancy.
• Conducted bilateral mesencephalotomies in 2 patients presenting with bilateral pain.
• Focused on patients with pain secondary to cancers of the nasopharynx, jaw, tongue, and neck.

Main Results:

• Mesencephalotomy was utilized as a treatment for intractable pain in 38 patients.
• The procedure was effective in managing pain in the head, neck, and upper trunk.
• Bilateral mesencephalotomy was necessary for 2 patients experiencing bilateral pain.

Conclusions:

• Mesencephalotomy is a viable neurosurgical option for intractable cancer pain.
• The procedure demonstrates effectiveness for pain in the head, neck, and upper trunk.
• Careful patient selection, including assessment for bilateral pain, is crucial for successful mesencephalotomy outcomes.
