Summary
Combined neck dissection and brachytherapy effectively treat recurrent nasopharyngeal carcinoma (NPC) with extracapsular spread (ECS). This approach, including mandatory flap reconstruction, yields satisfactory outcomes for nodal metastasis in NPC patients.
Area of Science:
- Oncology
- Head and Neck Surgery
- Radiation Oncology
Background:
- Recurrent nasopharyngeal carcinoma (NPC) presents challenges, particularly with nodal metastasis involving extracapsular spread (ECS).
- Optimal treatment strategies for recurrent NPC with ECS remain an area of active investigation.
- Previous treatments, including radiotherapy, influence subsequent management options.
Purpose of the Study:
- To evaluate the efficacy of combined neck dissection and brachytherapy for recurrent NPC with nodal metastasis and extracapsular spread (ECS).
- To compare treatment outcomes between patients with and without ECS.
- To identify and mitigate potential postoperative complications.
Main Methods:
- A prospective study involving 158 patients with regional recurrent NPC after radiotherapy.
- Patients with ECS underwent extended radical neck dissection (RND) followed by brachytherapy.
- Patients without ECS were treated with RND alone; outcomes were compared.
Main Results:
- Macroscopic ECS was present in 25.9% of patients.
- No significant difference in 5-year nodal control (62% vs. 65%) or disease-free survival (38% vs. 44%) was observed between patients with or without ECS.
- Regional flap reconstruction was utilized in 41 patients to prevent wound necrosis and carotid blowout; nerve palsies occurred at low rates.
Conclusions:
- Combined surgery and brachytherapy offer satisfactory results for recurrent NPC with ECS.
- Mandatory reconstruction with regional flaps is crucial to prevent severe complications such as wound necrosis and carotid artery blowout.
- This aggressive treatment strategy demonstrates acceptable safety profiles, with no cases of cerebral ischemia from accelerated atherosclerosis.

Detailed Structure and Function of Lymph Nodes
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Secondary Lymphoid Organs
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
