Symptoms of laryngeal cancer
Early symptoms: foreign body sensation and pain in throat, cough and blood in sputum, which can metastasize to ipsilateral deep middle cervical lymph nodes.
Late symptoms: After the cancer breaks, pain in the throat may occur, sometimes radiating into the ipsilateral ear, dyspnea, and metastasizing to the opposite side.
Related symptoms: foreign body sensation in throat, blockage in throat, cough, sore throat, hoarseness and difficulty breathing
Symptom diagnosis of laryngeal cancer
Often due to different types, the symptoms appear sooner or later and the severity of the disease are different. The main symptoms are:
It is the earliest symptom of vocal cord cancer, which is mostly persistent and gradually aggravated. The early symptoms of subglottic cancer are not significant, while hoarseness is a later symptom.
(2) Foreign body sensation and pain in throat:
It is often a symptom of supraglottic cancer in the early stage. After the cancer breaks, throat pain can appear, and sometimes it radiates into the ipsilateral ear, which is a symptom in the late stage.
(3) Cough and blood in sputum:
It occurs after cancer breaks, which is a common symptom.
It is a more advanced symptom, indicating that cancer has developed to block the laryngeal cavity.
(5) Cervical lymph node metastasis:
It can metastasize to ipsilateral deep middle cervical lymph nodes, and may metastasize to contralateral lymph nodes in late stage
According to the location of cancer, it can be divided into three different types
(A) Supraglottic type
(B) Glottic type
(3) Subglottic type
Staging of laryngeal carcinoma:
The letter T represents the size of the tumor and the scope of invasion of the primary tumor, T1: the tumor is limited to one side of the larynx; T2 tumors were located on both sides of the larynx; T3 tumor has caused the obstacle of vocal cord movement on one side; T4 tumor has invaded outside the larynx.
N indicates whether there is lymph node invasion, which is divided into four grades, namely N0, N1, N2 and N3. NO: No evidence of lymph node metastasis; N1: There is a suspicious lymph node with a diameter less than 3cm metastasis; N2: Lymph nodes are found on both sides of the neck, or there are more than two lymph nodes on one side, or the diameter of one side is greater than 3cm and less than 6cm; N3: A lymph node is more than 6cm in diameter.
The letter M indicates whether there is distant metastasis, and M0 indicates no metastasis; M1: Indicates metastasis;
The combination of T N M staging is the stage of laryngeal carcinoma:
Stage I: T1, N0 and M0;
Phase II: T2, N0 and M0;
Phase III: T3, N0 and M0; T1, T2, or T3, and N1, M0;
Phase IV: T4, N0 or N1, M0; Any T plus N2 or N3 and M0, or M1 plus any T or N;
T1 when the tumor is very small, T4 when distant metastasis occurs or invades adjacent structures (but excluding lymph nodes), and T4 when laryngeal cancer that has invaded lymph nodes reaches N2 or N3.
