Study to Calculate the Radiation Dosimetry in Subjects With Head and Neck Cancer
Lead Sponsor:
University of Iowa
Conditions:
Head and Neck Cancer
Eligibility:
All Genders
21+ years
Brief Summary
Preliminary observations suggest positron emission tomography (PET) imaging with an F-18 labeled thymidine analog (FLT) can selectively identify proliferating and non-proliferating tissues, including ...
Detailed Description
There are approximately 40,000 new cases of head and neck cancer each year in the United States. Worldwide more than 500,000 individuals will develop head and neck cancer each year, ranking as the six...
Eligibility Criteria
Inclusion
- Ability to understand and willingness to sign a written informed consent document.
- Subject must have histologically confirmed stage III, or IV squamous cell carcinoma of the head and neck whose primary origin was from the oral cavity, oropharynx, hypopharynx, or larynx. Carcinoma must be staged using the American Joint Committee on Cancer (AJCC) staging criteria version 6. Adequate tumor must be amenable to biopsy via outpatient methods, therefore the majority of subjects will be those with oropharyngeal lesions.
- Subjects must be scheduled to receive combined chemo-radiotherapy treatment for their standard cancer care. Treatment decisions will be made by the treating otolaryngologist, radiation, and medical oncologists.
- Males or females greater than or equal to 21 years of age. Squamous cell cancer of the head and neck is exceedingly rare in children and not generally applicable to the pediatric population.
- Karnofsky score greater than or equal to 60% at time of screening.
- Life expectancy of greater than 6 months.
- Subject must have normal organ and marrow function as defined below:
- leukocytes greater than or equal to 3,000/microL
- absolute neutrophil count greater than or equal to 1,500/microL
- platelets greater than or equal to 100,000/microL
- total bilirubin within normal institutional limits
- AST(SGOT)/ALT(SGPT) less than or equal to 2.5 X institutional upper limit of normal
- creatinine within normal institutional limits
- BUN within normal institutional limits
- PT and PTT \< 2.0 X upper normal limits
- The effects of FLT on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. A screening urine hCG will be administered to women of childbearing potential before each FLT scan.
Exclusion
- Subjects who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.
- Subject may not be receiving any other investigational agents.
- Subject with a Karnofsky score below 60.
- Pregnant women are excluded from this study. FLT PET has the potential for teratogenic effects. Because there are potentially unknown risks for adverse events in nursing infants secondary to treatment of the mother with FLT, breastfeeding should be discontinued if the mother is imaged with FLT and may not resume for 48 hours after the FLT imaging.
- Subject with an inadequate marrow reserve as determined by history and/or the above tests.
- Subject with a bleeding or clotting dysfunction as determined by medical history and above tests.
- Subjects taking nucleoside analog medications such as those used as antiretroviral agents.
- Inadequate tumor volume to allow for 2 biopsies.
