Overview

If left untreated, [#]% of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].

OR

Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].

OR

Prognosis is generally excellent/good/poor, and the 1/5/10-year mortality/survival rate of patients with [disease name] is approximately [#]%.

Natural History, Complications, and Prognosis

Natural History

The symptoms of familial amyloidosis usually develop:^[1]^[2]^[3]^[4]^[5]^[6]^[7]
- Transthyretin (TTR): After 50 years of age
- Apolipoprotein AI: Third decade and older
- Apolipoprotein AII: Early adulthood
- Fibrinogen Aa: Fourth to fifth decade
- Lysozyme: Third to fourth decade
- Gelsolin: Late adulthood
- Cystatin C: Third to fourth decade
In amyloidosis, insoluble fibrils of amyloid are deposited in the organs, causing organ dysfunction and eventually death.^[8]

Complications

In patients with amyloidosis, the most frequent complications include:^[9]

Prognosis

Prognosis is generally excellent/good/poor, and the 1/5/10-year mortality/survival rate of patients with [disease name] is approximately [--]%.
Depending on the extent of the [tumor/disease progression] at the time of diagnosis, the prognosis may vary. However, the prognosis is generally regarded as poor/good/excellent.
The presence of [characteristic of disease] is associated with a particularly [good/poor] prognosis among patients with [disease/malignancy].
[Subtype of disease/malignancy] is associated with the most favorable prognosis.
The prognosis varies with the [characteristic] of tumor; [subtype of disease/malignancy] have the most favorable prognosis.
