Metastatic Basal Cell Carcinoma: Next-Line Treatment After Smoothened Inhibitor Failure

Metastatic basal cell carcinoma (mBCC) is an advanced-stage disease that requires systemic management and close multidisciplinary oversight. When first-line systemic therapy does not achieve objective tumor response, a defined next-line strategy applies.

Previous Line — Why Escalation Is Needed

The recommended first approach for mBCC is multidisciplinary consultation together with systemic therapy using a smoothened (hedgehog pathway) inhibitor (oral vismodegib). The primary goal of this line is objective tumor shrinkage. When that goal is not reached — or when further treatment with a smoothened inhibitor is no longer feasible — the protocol escalates to the next line.

Next-Line Approach (Partial Overview)

Once smoothened inhibitor therapy is no longer viable, the management approach shifts to either a systemic cytotoxic option or a supportive and palliative framework — with the choice guided by individual patient factors.

Full criteria, sequencing, and structured evidence-based options are available in the complete protocol below.
