Clinical Trial
Clinical evaluation of granisetron as an inhibitor of nausea and vomiting induced by oral anticancer drugs.
In order to inhibit the nausea and vomiting induced by oral anticancer drugs, granisetron was administered orally at a dose of 2 mg once a day, and its usefulness and safety were evaluated. The subjects were 26 outpatients with gastric or colon cancer receiving chemotherapy with oral anticancer drugs and complaining of gastrointestinal symptoms. ⋯ In comparison with the condition before treatment, the patients were instructed to indicate on the record sheet the severity of nausea (4 grades), presence or absence of vomiting, and degree of appetite (4 grades) after treatment, and thereby to evaluate the clinical efficacy or antiemetic effect every day in accordance with clinical efficacy evaluation criteria of 4 grades (very effective, effective, slightly effective, and ineffective). i) Nausea disappeared in 47.8% of the patients on the 1st day of treatment and in 65.2% on the 5th day of treatment. ii) Vomiting was observed in 2 and 3 patients on the 1st and 3rd day, respectively, but not on the 4th day of treatment or thereafter. iii) The efficacy rate, comprising both very effective and effective, was 69.5% on the 1st day of treatment, and increased gradually to reach 78.2% on the 5th day of treatment. iv) There was no adverse reaction or abnormality of laboratory test values attributable to granisetron. Granisetron was safe and effective against nausea and vomiting induced by oral anticancer drugs.

Comparative Study
Comparison of 18F-fluoro-2-deoxyglucose positron emission tomography and gallium-67 citrate scintigraphy for detecting malignant lymphoma.
This study evaluates and compares the accuracy of positron emission tomography with 18F-fluoro-2-deoxyglucose (FDG-PET) and gallium-67 citrate (Ga-67) scintigraphy in identifying disease sites in patients with malignant lymphoma at initial diagnosis or relapse. Histology subgroups included low (n=5), intermediate (n=6), high-grade (n=5) non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD) (n=14). Ann-Arbor staging included 7 patients in stage I, 8 in stage II, 9 in stage II, 6 in stage IV and 11 extra-nodal. ⋯ In imaging lymphoma prior to therapy, FDG-PET had a higher sensitivity and detected significantly more disease sites when compared with Ga-67 scintigraphy in the initial evaluation of this group of patients. Upstaging of patients with FDG-PET may result in a change in treatment strategy. However, evaluation of the final sensitivity, specificity and accuracy of these imaging modalities will need a further study with a larger patient number.
