Beskrivelse
Inclusion Criteria:
AJCC pathological stage I-IV cancers of the head and neck meeting the following criteria:
- If gross total resection is performed it must be completed within 7 weeks of registration
- Site of tumor origin in the nasopharynx, oral cavity, oropharynx, parotid, larynx, or hypopharynx (excluding lip, or sinuses)
Pretreatment evaluations required for eligibility include:
- History and physical examination within four weeks prior to study entry
- Dental evaluation with management according to the guidelines in Appendix IV prior to start of radiation
- Serum pregnancy test, if applicable, within one week prior to study entry; urine dipstick test on the first day of treatment
- Radiographic Studies: Pre-operative CT or MRI of the primary tumor and neck for clinical staging is required
- Patients must be ≥ 18 years of age.
- Women of childbearing potential (WOCBP) must be willing to consent to using effective contraception while on treatment.
- Pregnant women are ineligible as radiation therapy involves unforeseeable risks to the embryo or fetus. WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [hCG], or in accordance with local regulations, whichever is more sensitive).
- Patients must sign a study-specific informed consent form prior to registration.
Exclusion Criteria:
- Histology positive for melanoma.
- Gross (visible or palpable) disease left after surgery.
- Less than gross total resection or patients requiring staged surgery.
- Prior head and neck radiotherapy.
- Women of childbearing potential (WOCBP) who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period

Postop IMRT for Head/Neck cancer
CT for Radiation Treatment Planning
|
Patients will be enrolled in study through the duration of their radiation therapy, approximately 6-8 weeks.
After which time no further evaluations will be made.
Andre navn:
Treatment planning CT scans will be required to define tumor, clinical, and planning target volumes.
This study requires CT scans prior to initiation of treatment then again on the third and sixth week of radiation treatment

Volumetric/Dosimetric Changes During IMRT for bulky and postoperative head/neck patients
Tidsramme: 7 weeks
|
To evaluate whether those patients undergoing standard intensity modulated radiation therapy (IMRT) for bulky and postoperative head and neck cancers demonstrate significant anatomic changes, causing dosimetric/volumetric changes during treatment which lead to under-dosing of tumor and/or over dosing of critical structures.
