To determine whether there is statisstical difference in FosB (FBJ murine osteosarcoma viral oncogene homolog B) protein expression between laryngeal cancer tissue and adjacent tissue through immunohistochemistry methods.
If there are differences, further the investigators will collect relevant patients information,such as clinical stages, pathological types, clinical prognosis and so on. ultimately analyze whether it is related to the expression of FOsB in laryngeal cancer tissue and adjacent tissues
laryngeal squamous cell carcinoma was diagnosed ,and biopsy was confirmed by two pathologists;
Primary tumor of Laryngeal ,and there was no distant metastasis;
Standard treatment such as surgery and Preliminarily-diagnosed parients;
full clinical and pathological data information and good follow-up;
Secondary cancer or cancer with distant metastasis;
Patients who have not seen a doctor for the first time or have received surgery or radiotherapy or chemotherapy in other hospitals;
Clinical and pathological data were missing and loss to follow-up;
