Input mode
Open RCP Composer
Core case inputs and decision-changing items. Detailed anatomy and teaching notes stay out of the way.
Scope: v1.0 encodes adult mucosal SCC/unknown primary, nasopharyngeal, salivary-gland and sinonasal pathways. Thyroid, cutaneous, skull-base, paediatric and other rare tumours are routed to dedicated disease modules. The country comparator reports source coverage; “Not computed” never means agreement.
Regression tests not run
Use “Run self-tests” above.

1. Clinical situation

Route the disease family first; then preserve the reported site-specific stage without deriving it.

Case
Why is stage group not computed?

Head-and-neck stage grouping changes by site, HPV association, EBV context and TNM edition. This release records the clinician-verified group and c/p/y prefixes but does not reproduce copyrighted staging tables or invent a group from incomplete data.

2. Diagnostic work-up and baseline function

Separate disease mapping from the supportive-function baseline that determines safe treatment.

Work-up
Baseline safety and rehabilitation

Document weight trajectory, oral intake/feeding support, dentition, aspiration risk, voice and swallowing before treatment. These are treatment-selection and survivorship variables, not cosmetic extras.

3. Site-directed biology

Only request biomarkers that answer a defined diagnostic, staging, prognostic or treatment question.

Biology

4. Surgery and pathological risk

Positive margin and extranodal extension are preserved separately from other postoperative risk factors.

Pathology

5. Anatomy, fitness and re-irradiation barriers

These inputs change the feasible pathway; they do not automatically select a substitute regimen or prescription.

Safety
Open BED/EQD2 Workbench →Reconstruction support only; expert interpretation remains required.
Open local RT Prescription Navigator →The Navigator transfers a rationale, not an automatically authorised prescription.

6. Follow-up, trials and source layer

Surveillance and trial hand-off remain tied to disease family, treatment and late-effect risk.
