Summary
Introduction:The primary tumour type most likely to metastasize to the brain is lung cancer. In heavily pre-treated patients, limited therapeutic option is available and the results of availability therapies reported in literature are disappointing. The present phase II study was designed to assess the efficacy and safety of temozolomide (TMZ) as palliative treatment for brain metastases (BrM) in NSCLC patients pre-treated with WBRT and at least one line of chemotherapy for metastatic brain disease. Material and methods: Temozolomide was administered orally at 150 mg/mq/day for five consecutive days for the first cycle, doses were increased to 200 mg/mq/day for 5 days every 28 days for subsequent cycles if no grade 3/4 haematological toxicity was observed. Eligibility criteria included cytological or histological confirmed NSCLC; BrM, recurrent or progressing after WBRT and at least one line of chemotherapy. A total of 30 consecutive patients entered the study and received the allocated treatment.Results: Three patients (10%) achieved an objective response (OR) of BrM with two complete remission. Stable disease and progressive disease were achieved in 3 (10%) and 24 patients (80%), respectively. A correlation between response to TMZ * Corresponding author. and sensitivity to the previous first line chemotherapy was reported. Time to progression and overall survival were examined both for responder patients and for all included patients. For long-term survivors, we considered the patients who survived >12 months after the start of TMZ. According to this definition, three patients resulted long-term survivors: 2 with OR and 1 with stable brain disease. No grades 3 or 4 toxicity occurred. The total of treatment-related adverse events were mild or moderate (G1-2) in intensity. No patients discontinued TMZ as a result of treatment-related toxicity. Discussion: The results of the present trial clearly demonstrates that TMZ is active and safe in BrM NSCLC patients previously treated with WBRT and at least one line of chemotherapy.
About one-third of the cases of non-Hodgkin's lymphomas occur in patients aged 60 years or more. Nevertheless, there are very few data in the literature regarding the optimal therapeutic approach for both aggressive and indolent histologies. Fludarabine-based combination regimens are an effective choice for younger patients affected by low-grade non-Hodgkin's lymphomas, but there is a lack of information about their tolerability and efficacy in older patients. We performed a phase II study to test the efficacy and safety of the combination of Fludarabine, Mitoxantrone and Dexamethasone (FND) in newly-diagnosed, chemo-naive elderly patients affected by low-grade non-Hodgkin's lymphomas with unfavorable prognostic factors. From March 1999 to March 2002, 18 patients were enrolled into the study. All the patients were evaluated for toxicity and response. Neutropenia and thrombocytopenia have been registered as the main toxicities. Thirteen (72%) patients experienced a complete response and 4 (22%) a partial response: the overall response rate was 94%. At a median follow-up of 19 months, the median time for progression-free-survival and the median survival time were not reached yet. The 2-years projected progression-free-survival and overall-survival are 52% and 67% respectively. When administered as first-line treatment to a population of elderly patients affected by high-risk, low-grade non-Hodgkin's lymphomas, FND showed a high efficacy and a good toxicity profile. Our data compare favorably to those reported for the same schedule administered both as first- or second-line therapy in younger patients.
e18026 Background: During the past five years the paradigms of advanced lung cancer therapy dramatically changed; Bevacizumab and Pemetrexed, when administered separately in association with platinum salts, demonstrated to improve survival in patients with non-squamous histologies. In the aim to investigate activity and safety of a three-drugs-regimen containing both these agents and cis-platinum, we conducted a multi-institutional phase II study started on november 2007. Methods: chemonaive patients with non-squamous non-small cell lung cancer were considered eligible We adopt the two-stage of Simon model as statistical design of the study; activity of the regime, expressed as overall response rate and safety were the main end-points. Administered doses were 75 and 500 mg/p.s.m for cis-platinum and pemetrexed respectively and 7.5 mg./kg for Bevacizumab, for 3 - 6 cycles. G-CSF were administered only after the first cycle of therapy, whereas vitamin supplementation started from day 1 of the first cycle. No maintenance therapy was allowed. Results: We registered 9 partial responses among the first 15 patients treated so, accordingly with the design of the study, we completed the enrollment up to 32 patients. Patients characteristics are: male/female: 20/12, median age (years): 59 (r. 36 - 77), ECOG-WHO/PS 0/1: 21/11. One hundred eighty-three cycles of CPBev were administered: we registered only 13 cases of grade 3 adverse events. No grade 4 toxicities were observed. One case of allergic reaction to cis-platinum were observed. In terms of response rate, we registered 20/32 (62.5%) partial responses, 8/32 (25%) stable diseases and 4/32 (12.5%) progressive diseases, with a clinical benefit rate of 28/32 (87.5%). Results in terms of outcome parameters expressed by progression-free and overall survival will be presented at the meeting. Conclusions: On the basis of our data, CPBev have a good toxicity profile and seems to be extremely active in advanced non-squamous lung carcinomas.
