A 55-year-old known smoker for 25 years presents with a low pitched voice. Endoscopy shows a mass limited to the vocal cord on the left. A biopsy is suggestive of laryngeal cancer type T1N0. Treatment of choice would be –
**Core Concept**
Laryngeal cancer, particularly T1N0, requires a treatment approach that balances oncological efficacy with preservation of vocal cord function. The primary goal is to achieve local control of the tumor while maintaining the patient's voice quality.
**Why the Correct Answer is Right**
For early-stage laryngeal cancer like T1N0, **surgical options** are often favored to achieve local control. The treatment of choice is **endoscopic laser surgery** or **open partial laryngectomy**. However, the most common and preferred surgical approach is **transoral laser microsurgery (TLM)** or **transoral robotic surgery (TORS)** for T1 glottic cancers. These minimally invasive techniques allow for precise tumor removal while preserving the vocal cord.
**Why Each Wrong Option is Incorrect**
**Option A:** Radiation therapy is often used for more advanced laryngeal cancers or in patients who are not good surgical candidates. However, for early-stage T1N0 laryngeal cancer, surgery is generally preferred to achieve local control and preserve vocal cord function.
**Option B:** Chemotherapy alone is not typically used as a primary treatment for early-stage laryngeal cancer. It may be used in conjunction with radiation therapy for more advanced disease.
**Option C:** Chemoradiation is a treatment option for more advanced laryngeal cancers or in patients who are not good surgical candidates. However, for early-stage T1N0 laryngeal cancer, surgery is generally preferred to achieve local control and preserve vocal cord function.
**Clinical Pearl / High-Yield Fact**
The **Tumor-Node-Metastasis (TNM) staging system** is crucial for determining the appropriate treatment approach for laryngeal cancer. A T1N0 classification indicates a small tumor limited to the vocal cord with no lymph node involvement, making surgical resection a viable option.
**Correct Answer:** C. Transoral laser microsurgery (TLM) or transoral robotic surgery (TORS) is the preferred treatment for early-stage laryngeal cancer like T1N0.
