What is the medium-term cure rate and survival rate of soft palate cancer, and what is the cause of death of soft palate cancer?
Soft palate cancer accounts for 13.5% of primary palatal malignant tumors. The most common pathological type is glandular epithelium, followed by squamous epithelium, malignant melanoma and sarcoma. Early symptoms are not obvious and easy to be ignored.

In the middle and late stage, there is an ulcer in the center, the edge is raised, or it grows outward, especially around the uvula. The soft palate tumor first spread to the tonsil arch and hard palate. It extends outward through the superior pharyngeal constrictor, invading the medial pterygoid muscle and skull base, and occasionally involving or compressing the cranial nerves in the parapharyngeal space. In the late stage, it often invades the nasopharyngeal side wall, causing perforation or ulceration of the soft palate.

Extended data

Palatal cancer often starts from one side and spreads rapidly to the gingival side and the opposite side. In the late stage, it can spread to soft palate, alveolar process and buccal gum. After invading the palatine bone, it can penetrate the nasal cavity and the bottom of the maxilla and enter the maxillary sinus, becoming a secondary maxillary sinus cancer. The diagnosis is not difficult, but biopsy can obviously confirm the diagnosis.

For palatal cancer, besides T 1 and T2, cryotherapy can be considered, and surgery is the main treatment. Comprehensive treatment of radiotherapy and chemotherapy.

Surgical indications:

1. The early tumor was confined to mucosa and periosteum, and the primary tumor was removed together with the palatine bone.

2. If the tumor spreads to the bottom wall of maxilla, subtotal maxillectomy is performed.

3. The tumor spread to the maxillary sinus, and there was no other wall bone destruction, so total maxillary resection was performed. In recent years, maxillary defects can be repaired with titanium mesh and prosthesis.

4. If the tumor spreads to hard palate and soft palate, full-thickness resection of hard palate and soft palate should be performed; Soft palate defect, soft palate reconstruction

5. Bilateral selective or therapeutic neck lymph node dissection should be performed in the neck of advanced palate cancer.
