Oncology dermatology · CTCAE v5.0

Grade cutaneous adverse events with clinical confidence.

Oncoderm is a focused, mobile-first tool for oncology teams to assess dermatologic toxicities, including erythema, scalp rash, pruritus, oral mucositis, and paronychia, and produce CTCAE-aligned grades in under a minute.

Why oncoderm exists

Cutaneous toxicity is the most common adverse event in targeted oncology therapy, and the least standardised to grade.

0%

of patients on EGFR inhibitors develop a papulopustular rash.

Lacouture ME et al. Oncologist 2008; Support Care Cancer 2011.

0%

of patients on immune-checkpoint inhibitors report itch or rash within 6 weeks.

Sibaud V. Am J Clin Dermatol 2018.

0.00 κ

inter-rater agreement on CTCAE skin grading between oncologists; fair, not strong.

Atkinson TM et al. JNCI 2016.

0%

of grade-3 dermatologic AEs trigger dose interruption or discontinuation when graded correctly.

Hassel JC et al. Eur J Cancer 2017.

Patients are penalised twice: by the skin toxicity itself and by the dose modifications that follow. Grading needs to be reproducible, photo-anchored, and fast enough to fit into a 7-minute oncology consultation. That is what Oncoderm is for.

What Oncoderm grades

Five clinical signs. One unified grading flow.

Each sign has its own clinical anatomy: photographic in some cases, questionnaire-based in others. Oncoderm hides that complexity behind a single mobile-first interface, and produces a CTCAE-aligned grade in every case.

Sign 01

Erythema

Skin redness, papulopustular rash, and acneiform eruption, the hallmark dermatologic toxicity of EGFR inhibitors.

Input
Single standardised photograph
Output
CTCAE Grade 1 – 3
  • G1 Papules and/or pustules covering <10% BSA
  • G2 Papules and/or pustules covering 10–30% BSA; limiting instrumental ADL
  • G3 Papules and/or pustules covering >30% BSA; limiting self-care ADL

Oncoderm’s erythema engine analyses tone, contrast and lesion density against a calibrated reference cohort. Output includes a heat-mapped overlay that lets the clinician verify the AI’s region of interest before signing the grade.

Sign 02

Scalp rash

Pustular folliculitis and seborrheic-pattern dermatitis on the scalp; frequent but underreported on standard CTCAE checklists.

Input
Three photos: front, top, back
Output
Detected / Not detected
  • Detected Pustular, follicular or seborrheic features present on ≥1 view
  • Not detected No features on any view

Three-angle capture catches lesions that a single dermoscopic shot misses. The model returns per-view confidence so the clinician can re-photograph an uncertain region rather than over- or under-grade.

Sign 03

Pruritus

Itch is the most disabling subjective symptom in cutaneous oncology toxicity, and it has no biomarker.

Input
NRS-11 itch + distribution + excoriation + ADL impact
Output
CTCAE Grade 1 – 3
  • G1 Mild or localized; topical intervention indicated
  • G2 Widespread and intermittent; oral intervention indicated; limiting instrumental ADL
  • G3 Widespread and constant; limiting self-care ADL or sleep

Four-question structured assessment combining the NRS-11 itch numeric scale with distribution, excoriation severity, and functional impact; collapses into a single CTCAE grade in real time on the device.

Sign 04

Oral mucositis

Stomatitis is the dose-limiting toxicity for many mTOR inhibitors, chemo-radiotherapy regimens and conditioning protocols.

Input
Symptom + dietary + functional questionnaire
Output
CTCAE Grade 1 – 4
  • G1 Asymptomatic or mild symptoms; intervention not indicated
  • G2 Moderate pain or ulcer; not interfering with oral intake; modified diet indicated
  • G3 Severe pain interfering with oral intake
  • G4 Life-threatening; urgent intervention indicated

Mucositis grading is binary in practice; patients either tolerate oral intake or they don’t. Oncoderm walks the clinician through a four-domain questionnaire and produces the CTCAE grade with a one-tap escalation flag for grades 3 – 4.

Sign 05

Paronychia

Inflammation of the periungual tissue, frequent with EGFR inhibitors and taxane regimens; under-detected because it tends to present late in the treatment cycle.

Input
Questionnaire (nail-fold finding, intervention, ADL impact)
Output
CTCAE Grade 1 – 3
  • G1 Nail fold edema or erythema; disruption of the cuticle
  • G2 Pustular discharge or nail plate separation; oral intervention indicated; limiting instrumental ADL
  • G3 Surgical intervention or IV antibiotics indicated; limiting self-care ADL

Paronychia grades on a three-factor questionnaire (visual finding, intervention level, ADL impact); the final grade is the highest of the three. The assessment is HCP-administered with the patient present, and no image AI is required.

And one more capability

When the lesion does not fit a CTCAE category

Oncoderm also returns a ranked differential diagnosis with risk metrics from a single photograph, to support the clinician in deciding whether to refer or biopsy. This output is diagnostic decision support, not a CTCAE grade.

How it works

Three taps from open to signed grade.

  1. 01

    Open Oncoderm

    No login. No app store. A clinician opens the URL on any phone, tablet, or laptop and starts immediately.

    Open Oncoderm
  2. 02

    Capture or answer

    For erythema and scalp rash, the camera UI guides standardised photographs. For pruritus and mucositis, four short structured questions.

    Capture or answer
  3. 03

    Sign the grade

    A CTCAE grade with rationale, anchored to the input. The clinician can override, attach a note, and export the assessment as a structured record.
