No guideline read says whether drugs that damage tissue if they leak can safely go through one.","summary":"The gap. None of the guidelines read for the midline protocol (CDC 2011, ESMO 2015, the Japanese extravasation guideline 2024) says whether vesicant or irritant chemotherapy may be given through a midline; the INS Standards, which address infusate limits, could not be read. The Japanese extravasation guideline cites a case report of oxaliplatin extravasation from a midline.\n\nThe evidence so far. A prospective Japanese study of 59 patients given continuous fluorouracil through a midline reported no phlebitis and complications in 6.8% (abstract). Whether this extends to vesicants and to irritants such as oxaliplatin has not been studied in any source read.","asOf":"2026-11-11","links":[{"label":"Sakakida et al., Midline catheter use for cancer patients receiving 5-FU chemotherapy (Oncologist 2025; abstract read)","url":"https://doi.org/10.1093/oncolo/oyaf108"},{"label":"JSCN/JSMO/JASPO multidisciplinary clinical practice guidelines for the management of extravasation of anticancer drugs (ESMO Open 2024)","url":"https://doi.org/10.1016/j.esmoop.2024.103932"}],"tags":["protocol-upgrade","upgrade:untested","evidence:insufficient"],"related":[],"cancers":[],"sections":["chemotherapy"],"technologies":["infusion-devices-vascular-access","picc-lines"],"targets":[],"drugs":["oxaliplatin","fluorouracil"],"companies":[],"institutions":[],"pathways":[],"terms":["extravasation-infusion-reaction"],"trials":[],"people":[],"bottlenecks":["b-toxicity-qol"],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"For continuous or repeated irritant chemotherapy, a midline with its tip in the axillary vein has an extravasation and phlebitis rate no higher than a PICC.","rationale":"Midlines avoid a central line's infection and placement burden; if they are safe for more drugs, many people could avoid a PICC, and if they are not, a clear limit would prevent injuries.","test":"A prospective registry of midlines used for anticancer drugs, recording drug class, dwell time, extravasation, phlebitis and infection, followed by a randomised comparison with PICCs for irritant infusions if the registry is reassuring.","maturity":"early-clinical","actor":"research","cost":"small","horizonYears":3},"route":"/ideas/idea-upgrade-midline-vesicant-safety-study/","neighbours":{"section":[{"id":"chemotherapy","kind":"section","name":"Chemotherapy","route":"/fronts/chemotherapy/"}],"technology":[{"id":"infusion-devices-vascular-access","kind":"technology","name":"Infusion pumps, ports, and ambulatory chemotherapy devices","route":"/technologies/infusion-devices-vascular-access/"},{"id":"picc-lines","kind":"technology","name":"Peripherally inserted central catheters (PICC lines)","route":"/technologies/picc-lines/"}],"drug":[{"id":"fluorouracil","kind":"drug","name":"Fluorouracil (5-FU)","route":"/drugs/fluorouracil/"},{"id":"oxaliplatin","kind":"drug","name":"Oxaliplatin","route":"/drugs/oxaliplatin/"}],"term":[{"id":"extravasation-infusion-reaction","kind":"term","name":"Infusion reactions, hypersensitivity and extravasation","route":"/terms/extravasation-infusion-reaction/"}],"bottleneck":[{"id":"b-toxicity-qol","kind":"bottleneck","name":"Toxicity and quality of life are undervalued","route":"/bottlenecks/b-toxicity-qol/"}],"protocol":[{"id":"midline-catheters-for-anticancer-therapy","kind":"protocol","name":"Midline catheters in cancer care: when to use one, insertion, care and limits","route":"/protocols/midline-catheters-for-anticancer-therapy/"}]}}
