A 55 year old known smoker since 25 years presents with a low pitched voice. Endoscopy shows a mass limited to the vocal cord on the left. Biopsy is suggestive of laryngeal cancer type T1NO. Treatment of choice would be
**Core Concept**
The question is testing the management of early-stage laryngeal cancer, specifically a T1N0 tumor, which is a type of squamous cell carcinoma confined to the vocal cord. The optimal treatment approach should balance cancer control with preservation of laryngeal function.
**Why the Correct Answer is Right**
For T1N0 laryngeal cancer, the treatment of choice is **surgical removal of the tumor with conservation of the larynx**, also known as **endoscopic laser surgery**. This approach allows for precise tumor excision while preserving the patient's voice and laryngeal function. The goal is to achieve a complete resection with negative margins while minimizing the risk of recurrence and complications.
**Why Each Wrong Option is Incorrect**
* **Option A:** Radiotherapy alone may be considered for patients who are poor surgical candidates or have a high risk of recurrence, but it is not the first-line treatment for early-stage laryngeal cancer.
* **Option B:** Chemotherapy is typically used as an adjunct to surgery or radiotherapy for more advanced disease, but it is not the primary treatment for T1N0 laryngeal cancer.
* **Option C:** Open surgery, such as horizontal partial laryngectomy, is generally reserved for more advanced laryngeal cancer or when endoscopic laser surgery is not feasible.
**Clinical Pearl / High-Yield Fact**
For patients with early-stage laryngeal cancer, the primary goal of treatment is to preserve laryngeal function while achieving a complete resection of the tumor. Endoscopic laser surgery is a minimally invasive approach that allows for precise tumor excision and can help maintain the patient's voice and quality of life.
**Correct Answer:** C. Open surgery, such as horizontal partial laryngectomy, is generally reserved for more advanced laryngeal cancer or when endoscopic laser surgery is not feasible.
