Altered fractionation for head and neck cancer.
A conventional course of radiation for squamous cell carcinoma in the United States is generally 70 Gy in 7 weeks, with a once-daily dose of 1.8 to 2 Gy. This schedule has a modest success rate in curing head and neck cancer. The past several decades have seen numerous investigations into altering this schedule to optimize the results of radiation. Two approaches, founded on radiobiologic princ...
متن کاملAltered Fractionation for Head and Neck Cancer
Delivery of therapeutic radiation in multiple sessions, or fractions, has been practiced since the discovery of radiation’s potential to cure malignancies. Initially, this was done out of practical necessity: Radiation was delivered at a low dose rate, and the treatment sessions had to be repeated to obtain the desired effect. Technologic improvements eventually allowed for treatments in one se...
متن کاملHead-to-head comparison of serum fractionation techniques.
Multiple approaches for simplifying the serum proteome have been described. These techniques are generally developed across different laboratories, samples, mass spectrometry platforms, and analysis tools. Hence, comparing the available schemes is impossible from the existing literature because of confounding variables. We describe a head-to-head comparison of several serum fractionation scheme...
متن کاملSurfaces of Constant Temperature for Glauber Dynamics
The wavefunction of a single spin system in a prepared initial state evolves to equilibrium with a heat bath. The average spin q(t) = p↑(t)− p↓(t) exhibits a characteristic time for this evolution. With the proper choice of spin flip rates, a dynamical Ising model (Glauber) can be constructed with the same characteristic time for transition of the average spin to equilibrium. The Glauber dynami...
متن کاملHead and neck cancer: altered fractionation schedules.
Local control is paramount in the treatment of localized advanced head and neck cancer. Standard radiotherapy cures a high percentage of early tumors--more than 80% of the early laryngeal tumors--but fewer of the advanced tumors. Attempts have therefore been made to improve the therapeutic ratio by: A) hyperfractionation: reducing the dose per fraction to reduce late morbidity; the total dose i...
