Comparative Study Clinical Trial
Comparison of fluorine-18 fluorodeoxyglucose positron emission tomography and Ga-67 scintigraphy in evaluation of lymphoma.
The accuracy of fluorodeoxyglucose positron emission tomography (FDG-PET; dual-head camera with attenuation correction) and Ga-67 scintigraphy was compared to identify disease sites in patients with Hodgkin disease (HD) and intermediate and high-grade non-Hodgkin lymphoma (NHL) at initial diagnosis or clinical recurrence. ⋯ In imaging aggressive lymphoma and HD before therapy, FDG-PET has significantly higher site and patient sensitivity than Ga-67 scintigraphy (100% vs. 71.5% and 100% vs. 80.3%, respectively). The change in disease stage by FDG-PET may result in a change in therapy strategy.

Most institutional teams utilize multimodality therapy in their efforts to cure patients with primary high-grade extremity soft tissue sarcomas, although the value of adjuvant systemic chemotherapy is still disputed by some oncologists. This single-institution Phase II study describes an effort to control metastasis by the use of two cycles of chemotherapy as the initial preoperative treatment. ⋯ IMAP plus GM-CSF is satisfactory as initial treatment for primary extremity soft tissue sarcomas in two monthly cycles preceding irradiation. The prescribed irradiation was generally tolerable and effective in permitting limb-sparing surgery. Although the outcome of patients treated on this regimen has been favorable, the metastasis problem has not been eliminated.

Clinical Trial
CPT-11 plus cisplatin in patients with advanced, untreated gastric or gastroesophageal junction carcinoma: results of a phase II study.
This Phase II study assessed the response rate and toxicity profile of the combination CPT-11 and cisplatin administered weekly to patients with untreated, advanced adenocarcinoma of the stomach or the gastroesophageal junction. ⋯ The combination of CPT-11 and cisplatin is active against gastric or gastroesophageal adenocarcinoma and needs to be studied further. A modification in doses and schedules may be warranted to make the regimen more tolerable to patients. The addition of other active drugs or radiation therapy to this regimen would be of interest.
