|Condition or disease||Intervention/treatment||Phase|
|Esophageal Cancer Lung Cancer Lymphoma||Drug: topotecan hydrochloride Radiation: low-LET electron therapy Radiation: low-LET photon therapy||Phase 1|
I. Define the maximum tolerated dose and safety profile of topotecan (TOPO) administered with daily high-dose thoracic radiotherapy to a total of 60 Gy in patients with solid tumor or lymphoma.
II. Assess the qualitative and quantitative nature of the toxic effects encountered in this treatment.
III. Estimate the tissue and tumor TOPO concentrations during radiotherapy by evaluating plasma TOPO levels.
IV. Evaluate, using Western blot and immunohistochemical stain, the effects of TOPO/radiotherapy on topoisomerase I levels in peripheral blood lymphocytes (PBL).
V. Determine whether TOPO induces apoptosis in PBL from this patient population.
VI. Examine tumor tissue pre- and post-treatment (if available) for topoisomerase I levels, DNA damage, topoisomerase I/DNA complexes, and apoptotic events.
