    Notes: Abstract Modulation of 5-fluorouracil (FUra) using leucovorin (LV) is a standard treatment approach in patients with metastatic colorectal cancer. Modulation of FUra with interferon alfa has also shown some promise. Laboratory data have demonstrated increased cytotoxicity when FUra is combined with both LV and interferon. The current study examined the effects of double modulation of FUra using LV and interferon. Patients with measurable advanced colorectal cancer received bolus FUra 375 mg/m2 plus LV 20 mg/m2 daily for 5 days, repeated every 28 days. Recombinant human interferon alfa-2a, 3 million IU/m2 subcutaneously, was given daily on the days of chemotherapy then three times weekly. There was one complete response and nine partial responses (10/41) seen for an overall response rate of 24% (95% CI 12.0–40.0%). Overall, 70% of patients experienced one or more episodes of nonhematologic toxicity of grade 3 or more. Weight loss was common, with a mean decrease of 2.9 kg over the first two months (P〈0.0001). Improvements in tumor-related symptoms were balanced by increased fatigue and a deterioration in body weight and performance status. There was no evidence of progressive changes in FUra metabolism from interferon usage.

    Notes: Abstract We tested the hypothesis that neurochemical changes in the spinal cord dorsal horn associated with neuropathic pain states differ from those seen in association with non-painful neuropathies. Immunohistochemistry was performed on spinal cord sections from rats with a chronic constriction injury (CCI), which develop hyperalgesia, and from animals with a nerve crush injury, which do not develop hyperalgesia or other signs of a painful syndrome. Immunohistochemistry was quantified by computer-assisted densitometry. Calcitonin gene-related peptide (CGRP) immunoreactivity and substance P (SP) immunoreactivity were decreased from 1 to 4 weeks after injury in CCI and from 2 to 6 weeks in crush. Gamma-aminobutyric acid immunoreactivity was unchanged in both conditions at all time points. Met-enkephalin (Met-enk) immunoreactivity was increased in CCI and unchanged in crush. Although SP and CGRP are involved in pain transmission, we conclude that their decrease in immunoreactivity is not specific for the CCI model, but rather a more general event in nerve de- and regeneration. The increase in immunoreactivity for the opioid peptide Met-enk, however, was only seen in the late phase of CCI, and may be specific for conditions associated with neuropathic pain and its resolution.
