SMG Sparing IMRT Thesis
Word Document · DOCX
What the Thesis Contains
The document is a full 10-chapter academic dissertation (~29 KB, formatted in Times New Roman, double-spaced, with justified alignment, page numbers, and a structured dose constraints table). Here is a summary of the structure and key content:
Structure at a Glance
| Chapter | Title | Key Content |
|---|---|---|
| 1 | Introduction | Background, problem statement, aims, significance |
| 2 | Anatomy & Physiology | SMG microanatomy; why SMG loss hits resting saliva hardest (65-70% of resting output) |
| 3 | Radiobiology of Injury | Two-mechanism model (membrane damage + progenitor cell death); dose-response kinetics |
| 4 | IMRT Principles | Technical basis of IMRT; PARSPORT trial; all-gland vs. parotid-only sparing |
| 5 | Patient Selection & Oncologic Safety | Level IB anatomy; HPV+ oropharynx, NPC, OSCC selection criteria; 0 level IB failures at ≤39 Gy |
| 6 | Dose Constraints & Planning | Evidence-based constraint table (SMG ≤39 Gy, parotid ≤26 Gy); contouring; adaptive RT |
| 7 | Clinical Outcomes | Hawkins et al. PROM data; all-gland model superior to parotid-only; swallowing outcomes |
| 8 | SMGT + IMRT | Surgical transfer technique; 75% salivary flow at 12 months; Scrimger et al. Phase II |
| 9 | Discussion | Evidence synthesis; risk stratification; limitations; clinical implications |
| 10 | Conclusions & Future Directions | 7 key conclusions; 6 future research priorities including MR-linac and stem cell sparing |
Core Evidence Cited
- Hawkins et al., 2018 (PMID 28823405) - 252 patients; cSMG Dmean ≤39 Gy = best PROM predictor; zero level IB failures
- Mercadante et al., 2025 (PMID 39792256) - Systematic review (51 RCTs); IMRT tissue-sparing has strongest prevention evidence
- Scrimger et al., 2018 (PMID 30175876) - Phase II RCT; SMGT + IMRT = 75% salivary flow at 12 months
- He et al., 2025 (PMID 39707740) - OSCC; SMG sparing feasible; no nodes within/medial to SMG
- DAHANCA 2025 Guidelines - Level IB and SMG contouring recommendations
- Scott-Brown's Otorhinolaryngology and Cummings Otolaryngology - Physiological and radiobiological foundations
