Metastasis

6.4K
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...

Pituitary metastasis is rare but life-threatening. Early diagnosis and understanding clinical signs of pituitary metastasis, often from breast cancer, can improve patient quality of life.

Area of Science:

  • Endocrinology
  • Oncology
  • Neurology

Background:

  • Tumor metastasis to the pituitary gland is a rare, poorly documented, and life-threatening condition.
  • Understanding its clinical manifestations is crucial for earlier diagnosis, timely treatment, and improved quality of life for patients.

Purpose of the Study:

  • To retrospectively analyze clinical data of patients with pituitary metastases.
  • To identify common primary tumor origins, clinical manifestations, and survival outcomes.
  • To compare findings with existing literature and enhance understanding of pituitary metastasis.

Main Methods:

  • Retrospective chart review of 11 patients treated at City of Hope National Medical Center (1984-2018).
  • Analysis of tumor origin, pituitary manifestation, time to metastasis, treatment, and survival.

  • Literature review and comparison of data from 289 reported cases (1957-2018).

    • Main Results:

    • The study identified 11 patients with pituitary metastases (mean age 59.2 years), median survival of 10 months.
    • Breast cancer and lymphoma were the most common primary origins.
    • Diabetes insipidus and panhypopituitarism were the most frequent clinical manifestations.
    • Literature review showed breast cancer as the most frequent primary origin and visual symptoms as the most common manifestation.
    • The posterior pituitary is more susceptible to metastasis than the anterior.
    • Pituitary metastasis can occur after successful primary tumor treatment.

    Conclusions:

    • Pituitary metastasis is a serious complication, with breast cancer being a frequent cause.
    • Clinical manifestations like diabetes insipidus and panhypopituitarism require attention for early detection.
    • Further research into the molecular mechanisms of pituitary metastasis is warranted.
