Overview
If left untreated, patients with papillary thyroid cancer may progress to develop metastasis. Common complications of papillary thyroid cancer include vocal cord compression, dysphagia, and dyspnea. The presence of metastasis is associated with a particularly poor prognosis among patients with papillary thyroid cancer. The 10-year survival rate papillary thyroid cancer is 99%.
Natural History
- The symptoms of papillary thyroid cancer usually develop in the third or fourth decade of life and start with symptoms such as a painless lump in the neck. Without treatment, the patient will develop symptoms of compression and metastasis, which may be fatal.[1]
Complications
- Complications of papillary thyroid cancer include:[1]
- Metastasis
- Involvement of recurrent laryngeal nerve
- Dysphagia
- Dyspnea
Prognosis
- Prognosis is generally excellent, and the 10-year relative survival rate of patients with papillary thyroid cancer is approximately 99%.[2]
- Prognosis of patients with papillary thyroid cancer depends on the following features:[3][4]
- Patient's age
- Size of the tumor
- Presence of metastatic disease
- Presence of tumor invasion into adjacent tissues
- Gender (male gender has been associated with higher mortality rate)
5 year Relative Survival Rate
- 5-year relative survival rate of papillary thyroid cancer depends on the invasion of the tumor at the time of diagnosis.[5]
- Localized tumor: 100%
- Tumor with regional metastasis: 100%
- Tumor with distant metastasis: 78%
