ECT, which combines chemotherapy with the application of an electric field to enhance drug uptake by tumor cells, has shown promise as a local treatment, particularly in cases where conventional therapies such as radiotherapy have been exhausted or are unsuitable. The review, conducted according to SANRA guidelines, included 18 studies, on ECT in anorectal tumors, ranging from preclinical trials in dogs to case reports and clinical studies in humans. The findings indicate that ECT can achieve high tumor overall response rates (70-100%) with minimal side effects, offering benefits such as tumor reduction and preserved organ function. These results highlight the potential of ECT to provide not only tumor reduction but also the preservation of vital organ function with a relatively low toxicity profile. However, further comparative research is necessary to substantiate its role as a standard therapeutic option. Moreover, the evidence is limited by significant heterogeneity across studies, small sample sizes, and a lack of comparative research with other local treatments like radiotherapy and cryosurgery. Consequently, while ECT appears to be a promising option, particularly for palliative care or in a neoadjuvant setting, it cannot yet be recommended as a standard treatment. Future research should focus on larger, more robust studies with standardized outcomes and explore the potential synergy between ECT and other therapies to establish its place in the treatment of anorectal tumors.<\/jats:p>","DOI":"10.1177\/15330338251349596","type":"journal-article","created":{"date-parts":[[2025,7,8]],"date-time":"2025-07-08T03:08:39Z","timestamp":1751944119000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Electrochemotherapy for Anorectal Tumors: A Narrative Literature Review"],"prefix":"10.1177","volume":"24","author":[{"given":"Martina","family":"Ferioli","sequence":"first","affiliation":[{"name":"Azienda Ospedaliero-Universitaria di Ferrara"},{"name":"Radiation Oncology, Department of Medical and Surgical Sciences (DIMEC), Alma Mater Studiorum - Bologna University, Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandra","family":"Arcelli","sequence":"additional","affiliation":[{"name":"Radiation Oncology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Savino","family":"Cilla","sequence":"additional","affiliation":[{"name":"Responsible Research Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-9966-6342","authenticated-orcid":false,"given":"Arina A","family":"Zamfir","sequence":"additional","affiliation":[{"name":"Radiation Oncology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giorgio","family":"Tolento","sequence":"additional","affiliation":[{"name":"Radiation Oncology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dajana","family":"Cuicchi","sequence":"additional","affiliation":[{"name":"Surgery of the Alimentary Tract, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy"},{"name":"Alma Mater Studiorum University of Bologna"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milly","family":"Buwenge","sequence":"additional","affiliation":[{"name":"Radiation Oncology, Department of Medical and Surgical Sciences (DIMEC), Alma Mater Studiorum - Bologna University, Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5202-3472","authenticated-orcid":false,"given":"Erika","family":"Galietta","sequence":"additional","affiliation":[{"name":"Radiation Oncology, Department of Medical and Surgical Sciences (DIMEC), Alma Mater Studiorum - Bologna University, Bologna, Italy"},{"name":"Radiation Oncology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3368-1810","authenticated-orcid":false,"given":"Bruno","family":"Fionda","sequence":"additional","affiliation":[{"name":"Fondazione Policlinico Universitario Agostino Gemelli IRCCS"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"Tagliaferri","sequence":"additional","affiliation":[{"name":"Fondazione Policlinico Universitario Agostino Gemelli IRCCS"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matteo","family":"Rottoli","sequence":"additional","affiliation":[{"name":"Surgery of the Alimentary Tract, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy"},{"name":"Alma Mater Studiorum University of Bologna"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gilberto","family":"Poggioli","sequence":"additional","affiliation":[{"name":"Surgery of the Alimentary Tract, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy"},{"name":"Alma Mater Studiorum University of Bologna"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessio G","family":"Morganti","sequence":"additional","affiliation":[{"name":"Radiation Oncology, Department of Medical and Surgical Sciences (DIMEC), Alma Mater Studiorum - Bologna University, Bologna, Italy"},{"name":"Radiation Oncology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,7,8]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02140894"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00261-007-9356-4"},{"key":"e_1_3_2_4_2","unstructured":"NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines\u00ae) Rectal Cancer Version 1.2024.
