An immunohistochemical study demonstrated significant reductions in α‐SMA and collagen I levels, both in the ablated area and in the residual tumor tissue (Figure 2E), suggesting that LAA ablation depleted CAFs and ECM in pancreatic cancer, which would contribute to decreasing the stromal desmoplasia and enhancing intratumoral permeability. The gene discussed is ACTA1; the disease is familial pancreatic carcinoma.
