Gemcitabine is a novel nucleoside analogue with activity in solid tumours. This study assessed the objective response rate to gemcitabine given weekly intravenously at a dose of 1250 mg/m2 for 3 weeks followed by 1 week of rest (one cycle) in chemonaive patients with inoperable non-small cell lung cancer (NSCLC). 161 patients with NSCLC were recruited from 10 sites in nine countries. Most patients had stage IIIb (31.3%) or IV (64.6%) disease, and 93.8% had a performance status of 0 or 1 according to the WHO scale. Of 151 evaluable patients, there were 3 complete responses and 30 partial responses lasting at least 4 weeks for an objective response rate of 21.8% (95% CI 15.5-29.3%). All responses were validated by an extramural Oncology Review Board. The mean duration of response was 8.8 months. The mean survival for all patients (16.1% of patients still alive 26 months after last patient started treatment) was 11.5 months. Improvements were also observed in secondary efficacy parameters such as performance status, weight, analgesic requirement, pain, and other disease-related symptoms including cough, dyspnoea, haemoptysis, anorexia, somnolence and hoarseness. Haematological and non-haematological toxicity was mild given the biological activity of gemcitabine. This study confirms gemcitabine as one of the most active agents in NSCLC with the added benefit of a modest toxicity profile and ease of administration on an out-patient basis. Gemcitabine is a suitable candidate for combination chemotherapy in patients with NSCLC.

Gemcitabine, a novel nucleoside analog, shows reproducible response rates of 20% and above in single-agent studies in non-small cell lung cancer. In the phase II studies reported, chemotherapy-naive patients received gemcitabine (starting doses, 800 to 1,250 mg/ m2) as a single agent on days 1, 8, and 15 of a 28-day cycle. In three large studies of 82, 84, and 161 patients, response rates were 22.5%, 20%, and 21.8%, respectively. The median duration of response in these studies was 8.1, 12.7, and 7.6 months, respectively. The median length of survival for all patients (responders and non-responders) was 8.1, 9.2, and 9.4 months, respectively. Three trials in Japan involving 206 patients produced response rates of 16.3%, 26.0%, and 20.9%. A US phase I/II study of gemcitabine at doses of 1,000 to 2,800 mg/ m2 recorded an overall response rate of 26% in a population of mainly stage IV (87%) patients. Responses were seen across disease stages and histologic subtypes in performance status 0, 1, and 2 patients and in the elderly. Gemcitabine produced marked benefit (lasting 2 to 5 months) in a number of disease-related symptoms, most notably cough, hemoptysis, and dyspnea. Improvements in performance status were seen in 52% of patients receiving gemcitabine. Gemcitabine was well tolerated with few of the side effects normally associated with cytotoxic drugs.

Recent studies have indicated that chemotherapy not only provides some survival benefit, but also reduces tumor-related symptoms and improves the performance status of patients receiving chemotherapy. Data from single-agent gemcitabine studies demonstrate improvements in a range of tumor symptoms, including cough, hemoptysis, pain, dyspnea, and anorexia, as well as increases in performance status. Indeed, more patients benefit from gemcitabine chemotherapy than suggested by the objective response rate. Surveys also have shown that patients are much more likely to accept chemotherapy for what is perceived by health care professionals as potentially small benefits. Gemcitabine has a role in the palliative treatment of patients with advanced non-small cell lung cancer.

PMID:Gemcitabine: symptomatic benefit in advanced non-small cell lung cancer. 920 9

The aim of the present phase II study was to assess the activity and safety of gemcitabine-cisplatin combination in advanced NSCLC, and to evaluate the impact of this regimen in terms of symptom benefit and quality of life (QOL). Eighty patients with pathologically confirmed advanced (stage IIIB and IV) NSCLC were enrolled into this study. Gemcitabine was administered on days 1, 8 and 15 at a dose of 1000 mg/m(2), and cisplatin was given on day 2 at a dose of 100 mg/m(2). The cycles were repeated every 4 weeks. The impact of treatment on QOL and on tumor-related symptoms was evaluated with the validated EORTC forms (QLQ-C30 and LC-13). The regimen was relatively well tolerated. Myelosuppresion was the principal toxicity. Grade 3/4 neutropenia, thrombocytopenia and anemia occurred in 58, 65 and 30% of patients respectively. In 143 cycles (35%) the administration of gemcitabine on day 15 was omitted due to myelosuppresion. Non-hematological toxicities were generally mild. Among the 76 patients available for response evaluation, there were 5 complete responses (7%) and 26 partial responses (34%); an overall response rate of 41%. The median duration of response was 8.0 months. The median survival for all 80 patients was 11.0 months and the actuarial 1-year survival probability 45%. During therapy global QOL improved in 22% of patients and particular functional domains increased in 19-37% of patients. Dyspnea was released in 36% of patients, fatigue in 45%, chest pain in 38%, shoulder pain in 27%, cough in 44%, and hemoptysis in 75%. The mean intensity scores of the last three symptoms decreased significantly with therapy. Our study confirmed relatively high efficacy of the gemcitabine-cisplatin combination in patients with advanced NSCLC. Of particular importance was that treatment with gemcitabine-cisplatin combination in a large proportion of patients was also associated with remarkable symptomatic release and with improvement of QOL. However, the high frequency of myelotoxicity-related gemcitabine omissions on day 15 of the cycle indicates that modification of the schedule should be considered in standard care.

PMID:A phase II study of gemcitabine plus cisplatin in patients with advanced non-small cell lung cancer: clinical outcomes and quality of life. 1175 Jul 16

The aim of the study was to assess the efficacy of a combination of gemcitabine and cisplatin in advanced non-small cell lung cancer. Twenty-five patients were included (13--IIIB, and 12--IV stage). Gemcitabine--1000 mg/m2 was given intravenously on days 1, 8, and 15, and cisplatin--100 mg/m2 on day 2. In 13 patients partial remission was obtained, in 8--stabilisation, and in 4--progression. Median survival was 12 months (range: 1.5-32 months). Mean time to progression was 6 months. Toxicity was tolerable and included mainly thrombocytopenia, neutropenia and anemia. In 11 patients pain relief was obtained. Furthermore cough, dyspnoea and hemoptysis disappeared in a proportion of patients. These results indicate the efficacy of the combination of gemcitabine and cisplatin regimen in advanced non-small cell lung cancer, and its acceptable toxicity.
