Summary
Familial papillary thyroid carcinoma (FPTC) shows a high recurrence rate. Key risk factors include family history, multifocality, vascular invasion, TNM staging, and ATA risk assessment.
Area of Science:
- Endocrinology
- Oncology
- Genetics
Background:
- Familial papillary thyroid carcinoma (FPTC) is a distinct subtype with poorer prognosis than sporadic PTC.
- Understanding FPTC recurrence is crucial for improved patient outcomes.
Purpose of the Study:
- To analyze recurrence rates in familial PTC (FPTC) patients treated with curative intent.
- To identify independent prognostic factors associated with FPTC recurrence.
Main Methods:
- Multicenter national study involving patients with confirmed FPTC.
- Utilized Cox regression and survival analysis for recurrence risk factor identification.
- Included TNM staging and American Thyroid Association (ATA) risk assessment.
Main Results:
- 252 FPTC cases analyzed with a mean follow-up of 90 months.
- Recurrence observed in 26.9% of patients.
- Independent recurrence predictors: number of FPTC cases in family, multifocality, vascular invasion, TNM stage, and ATA risk score.
Conclusions:
- FPTC exhibits a significant recurrence rate.
- Recurrence is strongly associated with family history, tumor characteristics (multifocality, vascular invasion), TNM staging, and ATA risk stratification.

14.5K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

02:59Cancer Prevention
7.6K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:20The Retinoblastoma Gene
4.6K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

02:38Mitogens and the Cell Cycle
7.7K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

02:15Replicative Cell Senescence
4.3K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...
