Core Tip

Core Tip: Pancreatic cancer has very poor prognosis with a 5-year overall survival of 5% and a median overall survival (OS) time of 8-12 mo. The concomitant use of modulated electro-hyperthermia (mEHT) in addition to chemotherapy has been introduced. mEHT has specific antitumor effects, increasing survival and tumor response. This was a retrospective data collection on 217 patients affected by locally advanced pancreatic cancer performed in 9 Italian centres, aiming to assess survival, tumour response and toxicity. The mEHT group had a greater OS (20 mo vs 9 mo, P < 0.001), higher number of partial responses (45% vs 24%, P = 0.0018) and a lower number of progressions (4% vs 31%, P < 0.001) than no-mEHT group. Adverse events were observed in 2.6% of mEHT sessions. mEHT have beneficial effects on survival and tumor response of stage III-IV pancreatic tumor patients, without adding toxicity.
