Figure 1. Schematic representation of the experimental workflow Syngeneic murine colorectal cancer (CRC) and breast cancer cells were treated with temozolo- mide (TMZ) and/or cisplatin (CDDP) at clinically relevant concentrations in a pulsatile schedule (2 days treatment followed by drug washout and cell passaging) for a total of 12 in vitro treatment cycles (priming phase). Drug concentrations were as follows: 25 μM for TMZ and 1.5 μM for CDDP. Additionally, CRC cells were also treated with the standard-of-care cytotoxic agents: 2 μM for 5-fluorouracil <t>(5FU),</t> 5 μM for oxaliplatin (Oxa), and 35 nM for SN38 (the main active metabolite of iri- notecan). Primed cells were kept in drug-free medium for two passages and then injected into immunodeficient and immunocompetent mice to study the extent of immunological control induced by treatment with chemotherapeutic agents (ed- iting phase). Whole exome sequencing (WES) was performed at baseline (T0), at the end of the in vitro priming phase (T1) and on established tumors at the end of the in vivo challenge phase (T2).

On day 6, when the average tumor volume was 60–100 mm 3 , mice were randomized into 5 treatment groups: CTRL (saline vehicle), TMZ (20 mg/kg day-1-5 weekly), CDDP (5 mg/kg day 1 weekly), TMZ + CDDP, and FOLFOXIRI (5FU 25 mg/kg day 1, oxaliplatin 3 mg/kg day 1, irinotecan 25 mg/kg day 1, weekly).
