Submitting to ESMO Open goes smoothly when your draft already matches the journal's own rules. Editors screen new manuscripts against the ESMO Open guide for authors before peer review, so formatting, structure, and required statements should be right on the first draft rather than repaired during upload. This template sets that structure up for you.
It is a manuscript shell aligned to ESMO Open. It covers front matter, the abstract the journal expects, a body organized to the journal's article types, and a reference list in the journal's required style. Confirm current scope and article types on the ESMO Open journal page before you draft.
Prepare the title, authors, affiliations, and ORCID iDs. Write the abstract to the journal's rule and word limit, organize the body to the article type, and apply the required reference style from the first citation. Complete every declaration (ethics, competing interests, funding, data availability) the ESMO Open guide for authors lists, and cite figures and tables in order.
The common failure modes are formatting or reference style that does not match the guide for authors, missing required statements, and an incomplete portal checklist. Clear all three against the ESMO Open guide for authors before you submit.
The shell mirrors what editorial staff check first: article-type fit, the abstract rules, required declarations, and the journal's reference style. For more detail see the author resources. When your draft is ready, upload it through Editorial Manager.

Read the ESMO Open guide for authors once before drafting and once before upload. Draft the abstract after results are stable. Set the reference style before adding citations. Keep a cover letter that states your contribution and fit to ESMO Open in under a page.
Skim two or three recent ESMO Open papers to calibrate depth and figure style. Make the novelty clear in the first two pages. Deposit data and code when the policy on the ESMO Open journal page requires it. Disclose any preprint or conference version with identifiers in the cover letter.
Do one focused pass against the ESMO Open guide for authors: scope, length, reference style, required declarations, and figure quality. Then submit through Editorial Manager.
