Sebaceous Gland Carcinoma (SGC)

Sebaceous Gland Carcinoma (SGC) most commonly develops in the eyelids, but it may also occur in the head, neck, and trunk regions, which are abundant in sebaceous glands. For the diagnostic and therapeutic of sebaceous gland carcinomas, Protheragen provides fully integrated solutions.

Introduction to Sebaceous Gland Carcinoma (SGC)

Sebaceous gland carcinoma (SGC) is iniost radial/elliptic benign skin tumor in origin clearn a and usually developes in eye-lids region. Much of this tumor is clinically challenging due to the fact that it is often local recurs and metastates in malignancy therefore the prognosis remains gravely unfavorable. Sebaceous carcinoma has been more commonly reported recently, particularly in elderly Caucasian and male men. Thus, there is an increasing need to understand the pathogenesis of SGC and develop appropriate diagnostic and therapeutic approaches.

Diagnostics Development for Sebaceous Gland Carcinoma

Molecular Diagnostics

The next generation sequencing (NGS) technology has made it easier to detect actionable alterations in the SGC profile which intellectually shed light on possible therapeutic strategies. For example, mutations are frequently found in TP53 and RB1 in periocular SGC, while extraocular SGC is often found with mutations in PIK3CA and PTEN.

Immunohistochemistry

EMA, adipophilin, and androgen receptor are typical markers for distinguishing SGC from other malignancies such as squamous cell carcinoma and basal cell carcinoma. IHC can detect molecular chaperones too, like XIAP and BAG3, which are overexpressed in SGC and aid in the tumor's survival and proliferation.

Epigenetic Markers

DNA methylation and histone modulation, among other types of epigenetic alterations, are now regarded as potentially useful diagnostic markers for SGC. For example, the E-cadherin gene is often SGC associated with promoter region methylation which results in absent E-cadherin expression. Thus, this epigenetic alteration indicates a certain stage of the disease.

MicroRNA Profiling

Pioneering efforts in miRNA profiling have uncovered the differential expression of several miRNAs including members of the miRNA-200 family in SGC. Due to their role in tumor progression and metastasis, these miRNAs could potentially act as diagnostic markers and therapeutic targets.

Therapeutics Development for Sebaceous Gland Carcinoma

  • Targeted Therapies
    The discovery of actionable mutations via NGS has enabled the development of targeted therapies. These include, but are not limited to, BTK, FGFR2, PDGFRB, HRAS, and NF1. For example, there has been demonstrated efficacy in preclinical models of SGC where inhibitors against the PI3K/AKT/mTOR pathway were used, suggesting possible use in the clinic.
  • Immunotherapy
    The use of immunotherapy, in particular the use of immune checkpoints PD-1/PD-L1, is gaining much attention in treating SGC. Case reports have been positive with regard to responses to therapeutic with pembrolizumab and other checkpoint inhibitors, notably with MSI or high tumor mutation burden.
