An Analysis of the Response of Human Tumor Microvascular Endothelium to Ionizing Radiation

NCT00132704 | Completed

• Study Type: observational
• Target: 149

Brief Summary

Doctors will take some tissue from the tissue removed during surgery in order to study how the blood vessels of the tumor respond to radiation therapy. The tissue obtained will be used to determine how these tumor blood vessels respond to radiation therapy delivered to the tumor, after it has been removed. This radiation is delivered in the research lab. This research is being conducted in order to develop new methods to treat tumors by radiation therapy. No additional surgery will be performed to obtain these samples, and only materials that remain after all diagnostic testing has been completed will be used.

Conditions

Ovarian Neoplasms; Colorectal Neoplasms; Melanoma; Small Cell Lung Cancer; Liposarcoma

Outcome Measures

Primary Outcomes (1)

• apoptotic response

  The peak apoptotic radiation response will be obtained for each of the tumor type and the result compared to that of the mouse experiments in Garcia-Barros (no formal testing only qualitative statements).

  2 years

Study Arms (2)

A

The experiments in Group A will be conducted in order to determine if human tumor microvascular endothelium displays similar dose parameters as mouse tumor endothelium, and if the microvascular endothelium of tumors of different types behaves in a similar fashion in its response to IR.

Radiation: Ionizing radiation (IR) therapy

B

The experiments in Group B will be conducted in order to determine if tumor endothelium isolated to near homogeneity demonstrates dose parameters similar to those used in single dose radiotherapy of brain tumors.

Radiation: Ionizing radiation (IR)

Interventions

Ionizing radiation (IR) therapy RADIATION

Tumors will be sliced into 0.5cm fragments, incubated in culture medium and then irradiated to evaluate the kinetics and dose-dependencies of the endothelial apoptotic response. We will irradiate tumor fragments ex vivo at 0, 7, 13, 15, 17, and 25 Gy.

A

Ionizing radiation (IR) RADIATION

Tissue fragments of a total quantity of at least a 4x4x4 cm3 will be required. For each tumor a paraffin block will also be made for routine staining and IHC. Endothelial cell populations (at least 500 cells) will then be exposed to radiation at 0, 7, 11, 13, 15, 17, and 25 Gy and harvested at 4, 5 and 8 hours post IR.

Study Population

undergoing surgery on the Neurosurgery, Hepatobiliary, Colorectal, Urology, Head and Neck, Gynecology, GMT and Thoracic Services at Memorial Sloan- Kettering Cancer Center.

You may qualify if:

• Patients who are felt to have adequate tumor volume for these studies, at least a 2 x 2 x 2 cm3 tumor by physical exam, imaging studies or colonoscopy reports
• Primary or recurrent tumors are eligible
• Patients must be suitable candidates for surgery
• Patients who have signed the informed consent

You may not qualify if:

• Patients who are not considered suitable candidates for surgery
• Patients who have received prior radiation therapy to the tumor being removed
• Patients who have received chemotherapy within 6 months of tumor removal
• Patients who are pregnant
• Patients may choose to be excluded at any time
• Minors are excluded from this study because there are expected to be very few minors with the tumor types which the investigators are evaluating in this study
