<jats:title>Background and purpose</jats:title>
<jats:p>Combining chemoradiotherapy (CRT) with deep regional hyperthermia (HT) shows promise for enhancing clinical outcomes in selected rectal cancer patients. This study aimed to integrate the evidence and evaluate the efficacy of this combined treatment approach.</jats:p>

<jats:title>Materials and methods</jats:title>
<jats:p>A systematic search of the PubMed, Scopus, and Mendeley databases was performed. This review was conducted according to the PRISMA guidelines. The quality of studies was evaluated using the Newcastle–Ottawa scale (NOS). Random-effects meta-analyses (DerSimonian and Laird) were performed. The primary outcome was pathological complete response (pCR), and secondary endpoints were overall survival (OS), disease-free survival (DFS), local recurrence-free survival (LRFS), and toxicity.</jats:p>

<jats:title>Results</jats:title>
<jats:p>In total, 12 studies were included, mostly of moderate quality. Patients with locally advanced rectal cancer (LARC; <jats:italic>n</jats:italic> = 760) and locally recurrent rectal cancer (LRRC; <jats:italic>n</jats:italic> = 22) were eligible. The pooled pCR rate was 19% (95% confidence interval [CI]: 16–22%) among all 782 patients and 19% (95%CI:16–23%) among 760 LARC patients. Due to significant study heterogeneity, survival outcomes were pooled by excluding LRRC patients. The pooled 5‑year OS rate among 433 LARC patients was 87% (95%CI: 83–90%). The pooled 5‑year DFS and LRFS in LARC patients were 75% (95%CI: 70–80%) and 95% (95%CI: 92–97%), respectively. There was a lack of consistent reporting of HT treatment parameters and toxicity symptoms among the studies.</jats:p>
</jats:sec>
<jats:sec>
<jats:title>Conclusion</jats:title>
<jats:p>The collective clinical evidence showed that neoadjuvant CRT combined with HT in rectal cancer patients is feasible, with a 19% pCR rate and excellent survival outcomes in long term follow-up.</jats:p>
