Summary
Pregnancy is safe for women with differentiated thyroid cancer (DTC) and papillary thyroid microcarcinomas (PMCs). Deferring treatment until after delivery is a safe option for both mother and child, with no increased risk of disease progression.
Area of Science:
- Endocrinology
- Oncology
- Reproductive Medicine
Background:
- Thyroid cancer is a common endocrine malignancy.
- Pregnancy can impact various physiological processes.
- The effect of pregnancy on thyroid cancer requires careful evaluation.
Purpose of the Study:
- To review the impact of pregnancy on women with differentiated thyroid cancer (DTC).
- To assess pregnancy outcomes in women with newly diagnosed DTC.
- To evaluate surveillance for papillary thyroid microcarcinomas (PMCs) during pregnancy.
Main Methods:
- Literature review of clinical studies.
- Analysis of pregnancy outcomes in DTC and PMC patients.
- Evaluation of disease progression and recurrence during pregnancy.
Main Results:
- Pregnancy is not linked to high-risk pathological features in DTC.
- Active surveillance for PMCs during pregnancy shows no increased disease progression.
- Response-to-therapy status accurately predicts recurrence in previously treated DTC patients planning pregnancy.
Conclusions:
- Deferring surgery for newly diagnosed DTC or PMCs until after delivery is safe.
- Pregnancy does not significantly worsen outcomes for most thyroid cancer patients.
- Response-to-therapy is crucial for managing previously treated DTC in pregnant women.

01:26Factors Affecting the Risk of Infection
13.7K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

03:03mTOR Signaling and Cancer Progression
4.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:23The Thyroid Gland
7.7K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

01:12Relative Risk
2.2K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
