This paper reviews the toxicity profile of gemcitabine, a novel anticancer drug. Gemcitabine has been administered using two different treatment schedules: once weekly or twice weekly for 3 weeks followed by a week of rest (one cycle). It was well tolerated and alopecia was not a problem. Toxicity was greater in the twice-weekly schedule. Comparing the once-weekly with the twice-weekly schedule, WHO grade 3 or 4 thrombocytopenia was reported in 4.7 and 25.6% of patients, respectively. Other hematological toxicity was minimal. Transient WHO grade 3 or 4 elevations of ALT and AST occurred in 9.2 and 7.2% of patients, respectively, in the once-weekly schedule. For the twice-weekly schedule the corresponding percentages were 12.2 and 13.8%. Symptomatic toxicity was greater in patients who received twice-weekly gemcitabine. Nausea and vomiting was mild and generally well controlled without 5HT3 antagonists. However, there was a greater incidence of nausea and vomiting on the twice-weekly schedule. Flu-like symptoms were documented in 19.8% of patients receiving once-weekly and 63.3% of patients receiving twice-weekly gemcitabine. Peripheral edema, not related to cardiac, hepatic or renal failure, was seen more often in patients on twice-weekly treatment. As the efficacy of gemcitabine in non-small cell lung cancer was equivalent when using both regimens, the better tolerated and more easily administered once-weekly schedule is recommended.

While many studies have demonstrated the prevention of nausea and vomiting in patients receiving moderately or highly emetogenic anti-cancer agents, there are few reports of mildly emetogenic anti-cancer agents. In the present study, we performed a 2-year multi-center study to determine the types and efficacy of antiemetic therapy administered in a total of 77 cancer patients who received mildly emetogenic anti-cancer agents between September 2015 and August 2017. The effectiveness of antiemetic therapy was evaluated based on the frequency of nausea and vomiting and use of rescue medication. This information was reported by patients and collected every 24 hours for 120 hours after the administration of anti-cancer agents with a mild emetogenic risk. The combination of 5-HT3 receptor antagonist(1 or 3 mg granisetron, 0.75 mg palonosetron) and 6.6 mg dexamethasone was the most common antiemetic therapy used in our patient population. There was no significant difference in the effectiveness of all 5-HT3 receptor antagonists that were evaluated. Gemcitabine and nab-paclitaxel were the most commonly used with a total of 64 patients receiving a combination of these mildly emetogenic agents. Poor performance status was associated with failure to achieve total control(TC)of nausea and vomiting(p=0.0304), while habitual alcohol consumption was associated with TC of nausea and vomiting(p=0.0331).
