At Mumbai's Kokilaben Dhirubhai Ambani Hospital, a new sentinel lymph node biopsy technique has spared 70 out of 75 early tongue cancer patients from extensive neck surgery. The method accurately detects microscopic lymph node spread, reducing unnecessary procedures and improving recovery times.

  • Sentinel lymph node biopsy spared 70 of 75 patients from major neck surgery.
  • Procedure involves only a 3 cm incision and averages a 4.5‑day hospital stay.
  • Clinical data confirm outcomes comparable to traditional surgery for selected patients.

Dr. Mandar Deshpande at Kokilaben Dhirubhai Ambani Hospital introduced the sentinel lymph node biopsy (SLNB) for early tongue cancer in 2023. In a series of 75 patients, 70 avoided extensive neck dissection, while only 5 required full surgery due to confirmed nodal involvement.

Clinical Workflow

The procedure begins with a small injection of a radioactive tracer into the tongue. Imaging tracks the tracer to identify the first lymph node it reaches. During surgery, surgeons locate and remove this sentinel node via a small incision, and an intra‑operative test determines the presence of cancer within 30 minutes. If the node is cancer‑free, the patient can avoid further dissection.

Limitations of Conventional Surgery

Traditional neck dissection often removes numerous nodes, causing pain, numbness, limited shoulder mobility, and larger scars. Dr. Deshpande notes that only 10‑20% of early tongue cancer patients actually have nodal metastasis, meaning many undergo unnecessary major surgery.

International Validation and Current Availability

SLNB has been validated in randomized controlled trials across Japan and Europe, showing comparable outcomes to standard treatment when appropriately selected. However, in India, the technique remains limited to a few centers due to the need for specialized nuclear imaging equipment and pathology expertise.

Why This Matters

BozokMedia analysis shows that reducing surgical extent not only improves patient quality of life but also lowers healthcare costs and resource utilization in tertiary care centers.
