The National Oncology Trainee Collaborative for Healthcare Research - a UK-wide trainee-led collaborative aiming to increase participation in cancer research and support resident doctors in gaining oncology research experience.
Conclusions:
🔵Acceptably low primary emergence rates

🔵Lower toxicity with INO radiotherapy

🔵No OS difference vs MUC

🔵INO may be a feasible alternative in modern practice

Involved neck only versus mucosal radiotherapy for head and neck squamous cell cancer of unknown primary (HNSCCUP): a national retrospective multicentre cohort study
Introduction: Target volumes for irradiation remain ill-defined for head and neck squamous cell cancer of unknown primary (HNSCCUP). The aim of this study was to compare two commonly used radiotherapy...

Survival Data (see paper for full data, and sub-group analysis)

5-yr OS was similar between INO and MUC RT groups, 82% and 80%.

Death from other causes (not HNSCUP) was higher in MUC RT cohort (p=0.003).

Primary site emergence was rare, occurring in only 3/195 patients (1.5%)

Treatment and toxicity:
🔵RT dose/fractionation differed notably, with MUC receiving higher-dose schedules.

🔵Acute feeding-tube use was higher in MUC (33% vs 11%, p<0.001).

🔵NTCP for grade ≥2 xerostomia at 6 months was significantly higher in MUC group

Study Design:
Retrospective observational multi-centre study
18 UK cancer centres

Outcomes of interest: OS, emergence of primary site, disease relapse/recurrence, toxicity, and enteral feeding rates.

Study Aims:
🔵The aim of the study was to directly compare involved neck only (INO) RT versus bilateral neck and/or mucosal irradiation in patients with unilateral HNSCCUP.
November 29, 2025 at 1:53 PM
Background:
🔵Management of HNSCCUP remains controversial, particularly regarding the optimal RT strategy, as traditional approaches have favoured comprehensive irradiation of bilateral neck and mucosal sites to minimize the risk of missing an occult primary.
