A 58-year old patient with metastasizing squamous cell carcinoma of the left lung developed fever, diffuse abdominal pain and profuse diarrhea while treated with paclitaxel and radiation therapy. A sigmoidoscopy was performed to exclude pseudomembranous colitis but showed multiple mucosal petechiae. Histologic examination disclosed neutropenic colitis. Conservative treatment was successful.

Radiotherapy vs. radiotherapy and razoxane in the treatment of soft tissue sarcomas: final results of a randomized study.

PURPOSE: The effect of the sensitizer razoxane on soft tissue sarcomas (STS) was prospectively evaluated in a randomized, controlled trial. The main purpose of the study was to determine the response rates and local control under the combined treatment compared to irradiation alone. METHODS AND MATERIALS: Between 1978 and 1988, 144 patients entered the study; 130 were evaluable for response, toxicity, or survival. The patients were randomized to receive radiotherapy alone or radiotherapy with razoxane. They were divided into postoperative cases and patients with gross disease (unresectable primaries, recurrent disease, or metastatic disease). The median radiation dose was 60 Gy postoperatively, and 56-58 Gy in patients with gross disease. The dose difference has palliative reasons. Razoxane was given orally at a daily dose of 150 mg/m2 during the time of the radiotherapy, starting 5 days before the first irradiation. In general, the groups were comparable as to their prognostic factors. There was some imbalance, however, in favor of the postoperative group reveiving radiotherapy alone. RESULTS: Between the patient groups treated postoperatively in an adjuvant form, there were no substantial differences in local control and survival. Among 82 patients with gross disease, the treatment with radiotherapy and razoxane led to an increased response rate compared to photon irradiation alone (74 vs. 49%). The local control rate was likewise improved (64 vs. 30%;p < 0.05). The acute toxicity was somewhat higher in the sensitizer arm, but there was no difference in the occurrence of late complications. CONCLUSIONS: Radiotherapy combined with razoxane seems to improve the local control in inoperable, residual, or recurrent STS compared to radiotherapy alone. The combined treatment is a fairly well tolerated procedure at low costs. It can be recommended for inoperable primary STS or gross disease after incomplete resection, conditions which are still associated with limited local control and a grave prognosis.
