glottis cancer

You have laryngeal cancer symptoms, such as hoarseness or other voice changes, a cough that won’t go away or trouble swallowing. What are the survival rates for stage 0 and stage 1 laryngeal cancer?

Step 1: Understand the context of laryngeal cancer

Laryngeal cancer is a disease in which malignant cells form in the tissues of the larynx, and it can be staged using various systems.

Step 2: Identify relevant information about survival rates for stage 0 and stage 1 laryngeal cancer

According to the provided context, early treatment of laryngeal cancer is crucial, and with it, the survival rates for stage 0 and stage 1 are excellent.

Step 3: Determine the specific survival rates mentioned in the context

The context does not provide a specific percentage or number for the survival rates but mentions that they are "excellent" for stages 0 and 1.

Step 4: Consider additional information about laryngeal cancer symptoms and treatment

Early detection of laryngeal cancer is key, as it can be asymptomatic in its early stages. Symptoms like hoarseness or coughing may indicate the presence of small growths on the vocal cords.

The final answer is: $\boxed{Excellent}$

Common Signs and Symptoms of Glottic Cancer

Glottic cancer, also known as vocal cord cancer, begins in the vocal cords. The most common symptom is changes to your voice, such as hoarseness or a weak voice that lasts longer than a few weeks [1]. This may be an early sign of the cancer affecting your vocal cords.

Other symptoms may include:

• Hoarseness: A persistent change in voice tone or pitch [2]
• Hemoptysis: Coughing up blood, if the tumors are large and have invaded nearby tissues [3]
• Prolonged cough: A cough that persists for more than a few weeks without any apparent cause [4]

It's essential to note that early glottic cancer may not have any symptoms at all. Small growths of the vocal cords may produce hoarseness or coughing, making it more likely to be diagnosed early [5].

If you experience any of these symptoms, it is crucial to consult a healthcare professional for proper evaluation and diagnosis.

However, small growths of the vocal cords may produce hoarseness or coughing, making glottic cancer more likely to be diagnosed early. (Search result 3)

Diagnostic Tests for Glottic Cancer

Glottic cancer, also known as vocal cord cancer, can be challenging to diagnose due to its location and symptoms that may mimic other conditions. However, several diagnostic tests are used to confirm the presence of cancer in the glottis (middle part) of the larynx.

• Endoscopy: A flexible tube with a camera is inserted through the mouth or nose to visualize the vocal cords and surrounding areas. This test can help identify abnormalities, such as tumors or lesions ([10][12]).
• Biopsy: A tissue sample is collected from the affected area using a biopsy needle or during an endoscopy procedure. The sample is then examined under a microscope for cancer cells ([5][15]).
• Imaging scans: Various imaging tests are used to visualize the extent of the disease, including:
  • CT scan (Computed Tomography): A CT scan uses X-rays and computer technology to create detailed images of the larynx and surrounding tissues ([8][11]).
  • MRI (Magnetic Resonance Imaging): An MRI uses magnetic fields and radio waves to produce high-resolution images of the larynx and surrounding areas ([5][11]).
  • X-ray: A chest X-ray may be performed to check for any potential spread of cancer to the lungs or other parts of the body ([4][8]).

These diagnostic tests help confirm a glottic cancer diagnosis, determine the stage of the disease, and guide treatment decisions. Early detection and diagnosis are crucial in improving patient outcomes.

Treatment Options for Glottic Cancer

Glottic cancer, also known as cancer of the vocal cords, can be treated with various methods, including drug treatment. While surgery and radiation therapy are often used to treat glottic cancer, drug treatment is also an option in some cases.

• Chemotherapy: Chemotherapy may be used in combination with other treatments, such as radiation or surgery, to kill cancer cells that have spread beyond the vocal cords.
• Targeted Therapy: Targeted therapy involves using medications that specifically target and destroy cancer cells. This type of treatment is often used for advanced glottic cancer.

Radiation Therapy

While not a drug per se, radiation therapy is an important aspect of treating glottic cancer. Radiation can be used to kill cancer cells in the vocal cords or surrounding areas. In some cases, chemotherapy may be given during radiation therapy to enhance its effectiveness.

• Standard Course of Radiation: A standard course of radiation for glottic cancer typically consists of a total of 60-70 Gy administered in single daily fractions over 6 weeks [6].

Treatment Options

The treatment options for glottic cancer depend on the stage and extent of the disease. In some cases, drug treatment may be used as part of a combination therapy approach.

• Stage II Cancer: Treatment options for stage II cancer of the glottis include surgery and/or radiation, and sometimes chemotherapy [4].
• Advanced Glottic Cancer: For advanced glottic cancer, treatment often involves a combination of surgery, radiation, and chemotherapy [11].

The differential diagnosis of glottic cancer involves identifying other conditions that may present similarly to glottic cancer. According to the provided context, some of these differentials include:

• Benign mucosal lesions:
  • Vocal nodules
  • Polyps
  • Granulomas
  • Amyloidosis [13]
• Benign neoplasms:
  • Papillomas
  • Haemangiomas
  • Granular cell tumors
  • Lymphangioma, etc. [13]
• Vocal cord leukoplakia
• Carcinoma in situ of the larynx
• Laryngeal tuberculosis

It's worth noting that glottic cancer is a type of laryngeal cancer that specifically affects the true vocal cords and anterior and posterior commissures of the larynx [10]. The differential diagnosis for glottic cancer should take into account its specific location in the larynx.

In terms of clinical features, laryngeal mucoepidermoid carcinoma is a rare entity that can also be considered in the differential diagnosis. It develops from the reserve cells in excretory ducts of submucosal glands or from squamous cells in the surface epithelium [11].

It's also important to note that glottic cancer has a good prognosis when managed appropriately, and it rarely requires surgical intervention beyond initial biopsy or tracheostomy in acute airway obstruction [10].
