Review[Recent progress in therapy for chronic myelogenous leukemia].
In chronic myelogenous leukemia (CML), abnormalities develop in hematopoietic stem cells, affecting three hematopoietic cell series, including leukocytes, erythrocytes, and platelets. The occurrence of the Philadelphia (Ph1) chromosome and BCR/ABL fused genes are involved in its pathophysiology. Methods of treating CML consist of bone marrow transplantation, and administration of interferon (IFN) and other antineoplastic drugs. ⋯ When bone marrow transplantation is impossible, administration of IFN is the treatment of choice. IFN administration may induce disappearance or a decrease in the Ph1 chromosome. IFN administration has been demonstrated to significantly increase the survival rate over conventional chemotherapy (hydroxyurea or busulfan).

Clinical Trial[Clinical evaluation of 2-mg granisetron tablet for nausea and vomiting induced by anticancer drugs including cisplatin].
The antiemetic effects on nausea and vomiting induced by anticancer drugs and safety of a 2-mg granisetron tablet were studied in cancer patients, particularly in the field of gynecology, who had been treated with anticancer drugs including cisplatin (CDDP) at 50 mg/m2 or more. The 1-mg granisetron tablet is already commercially available and used widely in clinical practice by oral administration of two tablets per dosage. In this investigation, the clinical efficacy, safety and usefulness of a 2-mg tablet, which can be taken more easily, were studied. ⋯ For safety, neither adverse experiences nor abnormal laboratory values were judged to be of clinical significance. The 2-mg granisetron tablet was considered "extremely useful" or "useful" in 22 (66.7%) of 33 patients. The above results confirmed the excellent antiemetic effect on nausea and vomiting induced by anticancer drugs including CDDP and the high degree of safety of a 2-mg granisetron tablet.

Multicenter Study Clinical Trial[Clinical efficacy of GG032X tablets, a new dosage form of ondansetron (fast dispersing tablet), on cisplatin-induced nausea and emesis].
The inhibitory effects of GG032X tablets, a new dosage form (fast dispersing tablet) of ondansetron, 5-HT2 receptor antagonist, on nausea and emesis induced by cisplatin (CDDP), were investigated along with safety and usefulness. Subjects were chemotherapy patients starting CDDP administration for the first time, who were receiving a high single dose of CDDP (50 mg/m2 or more and intravenous drip infusion of less than 4 hours), or lower multiple doses of CDDP (a single dose of 10 mg/m2 or more, administered intravenously for 3-5 consecutive days). GG032X tablets were administered orally 1-2 hours before CDDP administration. ⋯ Study results of these two groups were almost the same as those for already-approved ondansetron tablets. According to the results of questionnaires for the patients who participated in the study and took GG032X tablets, the drug was found to be easy to take and had favorable results. Based on the above results, GG032X tablets were evaluated as having the same inhibitory effect as the already-approved ondansetron tablets against CDDP-induced nausea and emesis, and were considered safe and clinically useful.

Clinical Trial[Clinical evaluation of 2 mg granisetron tablet for nausea and vomiting induced by anticancer drugs including cisplatin].
1. The clinical efficacy and safety of the 2 mg granisetron tablet were assessed in 32 mainly lung cancer patients who were to receive treatment with anticancer drugs including CDDP. 2. ⋯ The study medication was judged to be "safe" in 96.9% (31/32) of cases, without causing any adverse reactions. 5. The above results indicate that the 2 mg granisetron tablet is safe and useful.

Randomized Controlled Trial Comparative Study Clinical Trial[A randomized cross-over comparative study of granisetron alone and combination of granisetron, methylprednisolone and droperidol as antiemetic prophilaxis in CDDP-based chemotherapy for gynecologic cancer].
A cross-over clinical trial was carried out to compare the efficacy and safety of granisetron alone (40 micrograms/kg) as a "single" group, with that of granisetron, methylprednisolone (250 mg/ body) and droperidol (0.5 ml/body) as a "cocktail" group for control of emesis and vomiting induced by CDDP-based chemotherapy in 68 courses of 34 patients with gynecologic malignancies. At the first course, "single" or "cocktail" drugs were administered at day 1, 2, and 3 of chemotherapy, and at the second course, "cocktail" or "single" drugs in as cross-over fashion. We examined the degree of nausea and frequency of vomiting during the first 7 days of chemotherapy. ⋯ Clinical response (extremely good, good) in the current series of 68 courses of chemotherapy was also evaluated to be 45% and 35% in the "single" group, respectively, against 75% and 20% in the "cocktail" group, respectively. There was no clinical toxicity or side effects in either treatment group. We conclude that the cocktail treatment is very useful for not only acute, but also late emesis in CDDP-based chemotherapy in gynecologic malignancies.
