Clinical and Experimental Studies to Improve Radiotherapy Outcome in AIDS Cancer Patients

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.
Verified October 2011 by International Atomic Energy Agency.

The researchers plan:

  • To undertake clinical studies of radiotherapy with or without the administration of the chemotherapeutic agent cisplatin, known to be a radiosensitizer;
  • To perform pre-clinical studies of the radiosensitivity of human fibroblasts and cervical cancer cell lines in culture, with or without the addition of various HIV proteins or protease inhibitors, in order to determine the extent of any cellular radiosensitizing properties of these molecules;
  • To develop strategies for sensitizing tumour cells to radiation, specifically by down-regulating specific viral proteins that are known to be factors associated with resistance to radiotherapy.

Study Start Date: December 2004
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Radiotherapy alone
EBRT pelvis 46 Gy, 4 field box technique + ICBT LDR 1x30 Gy/A or HDR 3x8 Gy/A
Radiation: Radiotherapy alone
EBRT pelvis 46 Gy 4 field box technique + ICBT LDR 1x30 Gy/A or HDR 3x8 Gy/A
Experimental: Radiotherapy plus Chemotherapy
EBRT pelvis 46 Gy, 4 field box technique + ICBT LDR 1x30 Gy/A or HDR 3x8 Gy/A + weekly cisplatin 30 mg/m2 during EBRT
Radiation: Radiotherapy with cisplatin
EBRT pelvis 46 Gy 4 field box technique + ICBT LDR 1x30 Gy/A or HDR 3x8 Gy/A + weekly cisplatin 30 mg/m2 during EBRT

Detailed Description:
Clinical study addresses the question of whether radiotherapy plus weekly cisplatin offers an advantage over the same radiotherapy given alone in AIDS patients with cervix cancer. External beam radiotherapy is used with 50 Gy in 25 daily fractions (last interim analysis, October 2005) suggested lowering the total dose down to 46 Gy in 23 daily fractions). Brachytherapy component was specified as either 30 Gy of LDR in a single fraction or 3 fractions of 8 Gy using HDR. Cisplatin was administered weekly at a dose of 30 mg/sqm.
