Radiation vs Surgery for Vocal Cords Cancer: An Expert Guide

When it comes to treating vocal cords cancer, the decision between radiation therapy and surgery depends on several key factors. Each option has its own set of benefits and drawbacks. Here’s a detailed look at the considerations involved.

Early Stage Vocal Cords Cancer (T1 and T2)

For early-stage vocal cords cancer, typically categorized as T1 and T2, radiation therapy is often the preferred treatment method. This is due to its high efficacy and minimal invasiveness. Radiation therapy, especially external beam radiation, is virtually 100% curative for early-stage tumors (T1 and T2 Carcinoma in Situ (CIS)).

For tumor extension just slightly above or below the vocal cords, radiation remains highly effective, with cure rates around 90%. This category includes the T2 stage.

However, if the cancer has invaded beyond the mucosa into the vocal cord muscle (T3 Carcinoma In Situ), the success rate with radiation alone drops substantially to around 50%. In such cases, a hemilaryngectomy—surgical removal of half the larynx—may be more appropriate.

While radiation can still be attempted in these cases, the risks and outcomes must be carefully considered. If the cancer recurs after radiation, a total laryngectomy (removal of the entire larynx) is necessary, even if the initial treatment was radiation. This results in a 90% cure rate but at the cost of permanent voice loss and a tracheostomy.

Advanced Vocal Cords Cancer (T3 and T4)

For more advanced tumors, the approach changes. When the cancer has invaded the actual vocal cord muscle (T3) or spread to the cartilage or neighboring lymph nodes (T4), the options become more limited.

In cases where the cancer has spread to the local cartilage, a total laryngectomy is typically recommended. This surgical option provides the best long-term survival rates. However, it comes with the trade-off of permanent vocal loss and the need for a tracheostomy.

Concurrent chemotherapy can improve survival rates for T3 cancers, but the recurrence risk is still high. In such cases, a vertical hemilaryngectomy may be recommended to ensure complete tumor removal and to reduce the risk of recurrence.

For T4 cancers, where the tumor has spread to the surrounding lymph nodes or cartilage, a total laryngectomy is almost always the only viable option. Additional lymph node dissection may be performed if necessary.

Regardless of the stage, it is essential that patients discuss all treatment options with a multidisciplinary team, which typically includes head and neck surgeons, radiation oncologists, and medical oncologists. A thorough examination, including a laryngoscopy and review of imaging, helps in making an informed decision.

Conclusion

Choosing between radiation therapy and surgery for vocal cords cancer is complex and depends largely on the stage and specifics of the tumor. Both methods have their own sets of benefits and drawbacks, and the decision should be made after careful consideration and consultation with specialists.
