Metastasis02:30

Metastasis

7.0K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.2K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Summary
This summary is machine-generated.

Choroidal metastases, often from breast or lung cancer, require tailored treatment based on tumor characteristics and patient health. Management ranges from observation to radiotherapy or surgery for optimal outcomes.

Area of Science:

  • Ophthalmology
  • Oncology

Background:

  • The choroid is a frequent site for ocular metastasis due to its rich vascularization.
  • Breast and lung cancers are the primary sources of choroidal metastases, with distinct patterns of spread.

Purpose of the Study:

  • To review the diagnosis and treatment strategies for choroidal metastases.
  • To correlate primary cancer type with metastasis presentation.

Main Methods:

  • A comprehensive literature search was conducted on PubMed.
  • Keywords included "choroidal metastasis" and "treatment," "features," or "diagnosis."

Main Results:

  • Breast cancer accounts for 40-47% and lung cancer for 21-29% of choroidal metastases.
  • Bilateral, multifocal metastases suggest breast cancer; unilateral, unifocal suggest lung cancer.
  • Treatment is individualized based on systemic status and tumor characteristics.

Conclusions:

  • Choroidal metastases necessitate a multidisciplinary approach.
  • Treatment options are diverse, ranging from observation to local or systemic therapies and enucleation.
  • Understanding metastasis patterns aids in diagnosis and management planning.
