Is oestrogen an important player in melanoma progression?

Area of Science:

• Endocrinology
• Oncology
• Dermatology

Background:

• Oestrogen regulates cellular behavior through classical estrogen receptors (ERα, ERβ) and G protein-coupled estrogen receptor (GPER).
• Oestrogen dependency is established in breast, ovarian, and endometrial cancers.
• Growing evidence suggests melanoma may also be a hormonally dependent tumor.

Purpose of the Study:

• To explore the role of oestrogen in melanoma progression.
• To investigate the potential of targeting oestrogen pathways for melanoma therapy.

Main Methods:

• Review of existing literature on oestrogen receptors and their function.
• Analysis of studies reporting gender-related differences in melanoma.
• Examination of case reports on melanoma during pregnancy.

Main Results:

• Oestrogen receptors (ERα, ERβ, GPER) are present in the skin, indicating a local hormonal microenvironment.
• Observations of gender differences and pregnancy-related melanoma progression suggest a role for oestrogen.
• The precise effect of oestrogen on melanoma progression remains controversial but warrants consideration.

Conclusions:

• The skin's hormonal microenvironment, influenced by oestrogen, may play a role in melanoma.
• Further research into oestrogen's effect on melanoma is crucial.
• Targeting oestrogen pathways could represent a novel therapeutic strategy for melanoma.
