Charged Particle RT for Chordomas and Chondrosarcomas of the Base of Skull or Cervical Spine

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

The primary purpose of this study is to determine if the administration of a higher dose would decrease the chance of tumor recurrence, compared to the risk of tumor recurrence with a lower dose. Most of the treatment will be given protons, but participants may receive a small portion of treatment with x-rays, because less radiation is given to the skin with x-rays. This study uses two slightly different doses of radiation It is not clear at this time which of the dose levels is better.

Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • Establish acute and late toxicity rates for the different dose schedules. [ Time Frame: 5 years ]

Secondary Outcome Measures:
  • Establish local control rates for both dose schedules. [ Time Frame: 5 years ]
  • To provide date to be used as the basis for choosing the dose of charged particle radiation for chordomas of the base of skull and the cervical spine. [ Time Frame: 5 years ]

Enrollment: 274
Study Start Date: June 1999
Primary Completion Date: January 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Group 1
40-44 Treatments
Radiation: Charged Particle Radiation Therapy
Radiation doses will be determined by planning CT
Active Comparator: Group 2
37-40 Treatments
Radiation: Charged Particle Radiation Therapy
Radiation doses will be determined by planning CT

Detailed Description:
  • Participants will be assigned to a dose level by random chance, like flipping a coin.
  • A treatment plan will be determined by a treatment planning CT scan and will either involve 40-44 treatments or 37-40 treatments.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
