SOHO 2026 runs September 9–12, 2026 at the George R. Brown Convention Center, Houston, Texas.
This is a practical guide to the official poster and presentation rules for the Society of Hematologic Oncology's 14th Annual Meeting: the 55 × 35.5 in landscape poster and ePoster template, the August 28 ePoster upload deadline, what the abstract rules do and do not allow, where accepted abstracts are published in Clinical Lymphoma, Myeloma & Leukemia, and the hematologic oncology figures that make a poster worth stopping for. Every date and specification below links to official SOHO materials.

1. SOHO 2026 at a Glance: Dates, Venue, and Abstract Deadlines
SOHO 2026 runs September 9–12, 2026 at the George R. Brown Convention Center in Houston, Texas, as a hybrid meeting with in-person and on-demand access, and the abstract submission deadline is May 15, 2026 (11:59 p.m. CT). The presenting author must be a SOHO member — membership is free — and this is worth confirming early, since it is not required by comparable hematology or oncology meetings. Acceptance notifications are the one date where SOHO's own official pages disagree: the 2026 Submission Guidelines state "on or before June 12, 2026," while the Abstracts FAQ page says notifications go out "by June 15th" — so treat mid-June as the notification window and check your inbox (and spam folder) from June 12 onward.
Here is the SOHO 2026 timeline that matters, drawn from the official Submission Guidelines PDF and Abstracts FAQ.
| Date | Milestone |

| 15 May 2026 | Abstract submission closes (11:59 p.m. CT) |
| 12–15 June 2026 | Acceptance notifications sent (June 12 per Submission Guidelines PDF; June 15 per Abstracts FAQ) |
| 10 June 2026 | Early registration rate deadline |
| Wednesday, 9 September 2026 | Poster session; Poster Walks (guided group tours) run Wed–Fri lunch, Level 3, Poster Hall B3 |
| 28 August 2026 | ePoster upload deadline (11:59 p.m. CDT) |
| 31 August 2026 (5:00 p.m. CT) | Embargo lifts; accepted abstracts posted online |
| 9–12 September 2026 | SOHO 2026 Annual Meeting, George R. Brown Convention Center, Houston |

A SOHO 2026 poster and ePoster use the same 55 in wide × 35.5 in tall (140 cm × 90 cm) landscape template — and both a printed poster and an ePoster are required, since one does not substitute for the other. That dual requirement is easy to miss: SOHO's official ePoster instructions state plainly that "the ePoster submission does not take the place of your printed poster. Both formats are required for SOHO 2026." Building both from one landscape file keeps the layout consistent.
These SOHO 2026 poster size and format rules come from the official ePoster creation guidelines, distributed by SOHO's designated ePoster vendor. A few points shape how you build the sheet:
- 55 × 35.5 in (140 × 90 cm), landscape — a single-page PDF, not a multi-slide deck.
- Header text no smaller than 0.5 in (36 pt); body text no smaller than 0.25 in (14 pt) — use upper-and-lower case, not all caps, for readability.
- File naming convention:
category-poster number-poster.pdf(for example,HL-001-Poster.pdf). - Poster Walks: guided group tours through the Poster Hall (Level 3, Poster Hall B3) run Wednesday through Friday at lunch, with a poster leader walking each group through the top posters in a disease category — so a poster that reads clearly from a few feet away, not just up close, matters here.
The signaling-pathway and cell-therapy figures on a SOHO poster — BTK/BCR signaling, BCL2-pathway apoptosis, a CAR-T construct — are usually the slowest part of that layout to produce. You can generate publication-grade versions online for free and drop them straight into your poster file.

Start from a BCR/BTK pathway, a BCL2 mechanism, or a CAR-T construct before you open your poster template.
Explore the Tool3. SOHO 2026 ePoster: Requirements and the August 28 Upload Deadline
Every accepted SOHO 2026 abstract requires an ePoster, uploaded through the official submission portal by August 28, 2026, at 11:59 p.m. CDT. Submission happens at
soho2026.epostersubmission.com using a unique Poster Submission Code emailed to each corresponding author; the wizard also accepts an optional video (single .mp4 file, up to 2 GB), which SOHO strongly encourages but does not require.The ePoster uses the same 55 × 35.5 in landscape PDF as the printed poster (see §2), and resubmission is allowed anytime before the deadline if you need to fix a typo or swap a figure. Because the ePoster stays available to registrants after the meeting, a crisp vector-style figure holds up on screen far better than a scanned or photographed panel — a pathway diagram exported cleanly stays legible when someone zooms in later.
4. SOHO 2026 Oral Abstract Presentations: What's Confirmed and What's Still TBD
SOHO reserves oral presentation slots for abstracts the Scientific Committee judges "exceptional" during review, but as of July 21, 2026, SOHO had not published a general oral presentation time limit or slide template on its official pages. If your abstract is selected for an oral slot, the specific format arrives with your acceptance notification — so do not assume a slide ratio or time limit until you see it in writing.
What does not depend on that detail: an oral abstract slot at SOHO is still a short, focused presentation to a hematology and oncology audience, and nearly every slide benefits from one clear figure — a pathway schematic, a construct diagram, a trial or cohort schema — doing the explaining instead of a wall of text or a dense table.
5. What Figures Do You Need? SOHO 2026 Poster and Presentation Figures
Whether you are building a poster or oral slides, SOHO's hematologic oncology audience expects the same core figures — and unlike some meetings, SOHO abstracts cannot carry any at all, so your poster and slides are where the visual story has to live. SOHO's abstract rules are explicit: "no tables, figures, graphs, or images are allowed in the abstract submission." That makes the poster and any oral slides the only place your mechanism, construct, or study design gets drawn — there is no fallback abstract figure to lean on.
Across the meeting's 13 disease categories — from acute leukemias and lymphomas to multiple myeloma, MDS/MPN, and cellular therapy — three figure types recur on posters and slides:
- Signaling pathway or mechanism of action (MOA) — BCR/BTK signaling in CLL and mantle cell lymphoma, or BCL2-pathway apoptosis in the context of venetoclax, drawn with the correct upstream-to-downstream order.
- CAR-T or adoptive cell therapy construct — the scFv, hinge, transmembrane, costimulatory domain, and CD3ζ signaling tail, central to the meeting's cellular therapy track.
- Trial or cohort schema — the study design, arms, and endpoints behind your data, drawn with publication-grade clarity for a poster or a single slide.
Each of these historically takes hours in Adobe Illustrator or PowerPoint's shape tools. You can generate them from a text prompt or turn your accepted abstract into a starter figure instead, then refine and export to your 55 × 35.5 in poster template.

Try Free6. Designing a Winning SOHO Poster: Accuracy That Survives Peer Scrutiny
A winning SOHO poster passes two tests: it is grasped in a few seconds during a Poster Walk, and it is scientifically exact enough to survive scrutiny from a hematologist standing in front of it. The best layouts are built around one dominant "hero" figure — usually the pathway MOA or the CAR-T construct with the key result nearby — with everything else arranged to support it on the 55 × 35.5 in landscape sheet.
The second test is where scientific figures live or die — and where general-purpose AI image generators fall short. A tool like Nano Banana Pro or GPT Image can produce something that looks about 99% right, but on a scientific figure 99% right is effectively 0% right: a reversed pathway arrow, a mislabeled domain, or an inverted mechanism turns a compelling poster into one that misleads a reviewer. A flat, raster AI image also gives you no way to fix that last one percent.
This is the core difference with SciFig. Every figure is a fully editable SVG whose elements — arrows, labels, receptors, domains — you can correct individually, so you, the author who actually knows the biology, close the gap to 100% and sign off on the science. The hematologic oncology figures that reward this care are exactly the ones reviewers scrutinize:
- BCR/BTK pathway — get the signaling order right (BCR cross-linking → SYK → BTK → NF-κB/NFAT); a common mistake places BTK upstream of the B-cell receptor itself.
- BCL2-pathway apoptosis — BCL2 normally restrains pro-apoptotic BAX/BAK and BIM; a venetoclax mechanism figure that shows BCL2 promoting apoptosis has inverted the biology.
- CAR-T construct — get the domain order right (scFv, hinge, transmembrane, costimulatory domain, CD3ζ); a construct missing the CD3ζ signaling tail is the detail a cell-therapy reviewer notices first.
Whether your SOHO 2026 poster earns attention during a Poster Walk comes down to whether these figures are accurate, clear, and legible from a few feet away — which is exactly where an editable AI figure workflow compresses days of design work into hours without giving up scientific control.
7. Create Your SOHO 2026 Figures with AI: The SciFig Workflow
You already have two things most colleagues do not: your accepted abstract and a clear understanding of your study's mechanism — use both to generate your figures online for free, then edit them until they are exactly right. Here is the SciFig workflow for a SOHO presenter:
Path 1 — Upload your accepted abstract. Drop it into PDF-to-Figure. It parses your background and methods and returns a starter pathway diagram or trial schema in one click — a 70%-there draft, not a blank canvas.
Path 2 — Copy a structured prompt. For a mechanism or pathway figure, Text-to-Figure gives more control. Copy and adjust to your study:
Schematic of BCR/BTK signaling in chronic lymphocytic leukemia: B-cell
receptor cross-linking activates SYK, which activates BTK, driving
downstream NF-kB and NFAT signaling and B-cell survival; show a BTK
inhibitor blocking the kinase and interrupting the cascade.
Path 3 — Sketch and scan. If you sketched your hero figure on paper, photograph it and drop it into Sketch-to-Figure to get a publication-style version that preserves your topology.
From any path, you edit individual elements in the vector canvas — labels, arrows, domain placement — and export to editable PPTX or layered SVG for final composition, at high resolution for the 55 × 35.5 in poster without artifacting. A new SciFig account starts with 150 starter credits plus 50 refill credits every day, which covers a full set of poster figures for most authors. For the companion guides in this conference series, see the ASH 2026 poster guide and the EHA 2026 poster guide.
Optional — disclose your AI use. SOHO has not published a specific generative-AI policy, but many journals and meetings now ask authors to disclose AI assistance and remain responsible for accuracy. If you build and review a figure in SciFig, you can add one line to its caption — for example: Figure created by the authors using SciFig and reviewed for scientific accuracy (scifig.ai).

Use the path that matches what you already have, then edit every element until the science is exact.
Try Free8. SOHO 2026 Abstract Awards, Disease Categories, and Disclosure Rules
SOHO 2026 awards eight poster prizes — $2,500 for first place, $1,750 for second, $1,000 for third, and $500 each for five honorable-distinction posters — and every abstract must state whether informed consent was obtained and disclose any off-label drug use. Abstracts are organized into 13 disease categories: acute lymphoblastic leukemia, acute myeloid leukemia, cellular therapy, chronic lymphocytic leukemia, chronic myeloid leukemia, Hodgkin lymphoma, aggressive B-cell lymphoma, indolent B-cell lymphoma, mantle cell lymphoma, T-cell lymphoma, myelodysplastic neoplasms, myeloproliferative neoplasms, and multiple myeloma.
SOHO does not run a separate conflict-of-interest disclosure form the way some societies do — the informed-consent and off-label statements live directly in the abstract text, per the official Submission Guidelines. Accepted poster presenters also receive complimentary meeting registration, on top of eligibility for the eight cash awards judged on novelty, significance, and clarity.
Tip
The single highest-leverage decision in your preparation window is which figure becomes the hero on your 55 × 35.5 in sheet. Pick the one your Poster Walk group needs to remember afterward — usually the pathway MOA or the CAR-T construct with the key result nearby — and design the rest around it.
9. Where SOHO 2026 Abstracts Are Published (Clinical Lymphoma, Myeloma & Leukemia)
Accepted SOHO 2026 abstracts are reprinted for distribution in the Meeting Proceedings supplement of Clinical Lymphoma, Myeloma & Leukemia (CLML), and the embargo on accepted abstracts lifts August 31, 2026, at 5:00 p.m. CT, when they are posted online. Searches for "SOHO 2026 abstracts" or "SOHO abstract book" almost always mean this CLML supplement, published just before the meeting opens.
Because your abstract text cannot carry a figure (see §5), it is worth making sure the mechanism or pathway your poster and slides depict tells the same story a reader would infer from your published CLML abstract text alone.
