Randomized study of vinorelbine--gemcitabine versus vinorelbine--carboplatin in patients with advanced non-small cell lung cancer.

PURPOSE: The objective of this trial was to compare two vinorelbine-based doublets with carboplatin (CBDCA-VC) or with gemcitabine (VG) in patients with stage IIIB-IV non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: A total of 316 patients with advanced NSCLC previously untreated were randomized to either vinorelbine 30 mg/m(2) D1,8 with carboplatin AUC 5 D1 (VC) or vinorelbine 25mg/m(2) with gemcitabine (VG) 1000 mg/m(2) both given D1,8 every 3 weeks. The primary endpoint was response rate with secondary parameters being survival (OS), progression-free survival (PFS), tolerance and clinical benefit. RESULTS: The median number of cycles was four in each arm with a total of 1268 cycles. The objective response (OR) on intent-to-treat was 20.8% in VC and 28% in VG (p=0.15). Median PFS was 3.9 months in VC and 4.4 months (mo) in VG (p=0.18). Median survival was significantly longer (p=0.01) for VG with 11.5 mo compared to 8.6 mo in VC with 1 year survival at 48.9 and 34.4%, respectively. Tolerance was better in the VG arm as compared to the VC patients. Four toxic deaths were recorded in the VC group. Clinical benefit response rate was 32.4% compared to 40.9% in 111 and 110 evaluable patients in VC and VG, respectively. CONCLUSION: VG compared to VC resulted in a similar overall response rate, favourable median survival and a better toxicity profile. For non-cisplatin-based chemotherapy, VG is a useful alternative.

SRL172 (killed Mycobacterium vaccae) in addition to standard chemotherapy improves quality of life without affecting survival, in patients with advanced non-small-cell lung cancer: phase III results.

BACKGROUND: This open-label, randomised phase III study was designed to further investigate the clinical activity and safety of SRL172 (killed Mycobacterium vaccae suspension) with chemotherapy in the treatment of non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients were randomised to receive platinum-based chemotherapy, consisting of up to six cycles of MVP (mitomycin, vinblastine and cisplatin or carboplatin) with (210 patients) or without (209 patients) monthly SRL172. RESULTS: There was no statistical difference between the two groups in overall survival (primary efficacy end point) over the course of the study (median overall survival of 223 days versus 225 days; P = 0.65). However, a higher proportion of patients were alive at the end of the 15-week treatment phase in the chemotherapy plus SRL172 group (90%), than in the chemotherapy alone group (83%) (P = 0.061). At the end of the treatment phase, the response rate was 37% in the combined group and 33% in the chemotherapy alone group. Patients in the chemotherapy alone group had greater deterioration in their Global Health Status score (-14.3) than patients in the chemotherapy plus SRL172 group (-6.6) (P = 0.02). CONCLUSION: In this non-placebo controlled trial, SRL172 when added to standard cancer chemotherapy significantly improved patient quality of life without affecting overall survival times.

Circulating nucleosomes in serum.

In the nucleus of eukaryotic cells, DNA is associated with several protein components and forms complexes known as nucleosomes. During cell death, particularly during apoptosis, endonucleases are activated that cleave the chromatin into multiple oligo- and mononucleosomes. Subsequently, these nucleosomes are packed into apoptotic bodies and are engulfed by macrophages or neighboring cells. In cases of high rates of cellular turnover and cell death, they also are released into the circulation and can be detected in serum or plasma. As enhanced cell death occurs under various pathologic conditions, elevated amounts of circulating nucleosomes are not specific for any benign or malignant disorder. However, the course of change in the nucleosomal levels in circulation of patients with malignant tumors during chemotherapy or radiotherapy is associated with the clinical outcome and can be useful for the therapeutic monitoring and the prediction of the therapeutic efficacy.

UFT/leucovorin plus weekly paclitaxel in the treatment of solid tumors.

The palliation of symptoms and improvement of quality of life are important aspects of therapy in patients with incurable metastatic cancer. This article describes the preliminary results of a phase I study of uracil and tegafur, an orally available fluorouracil (5-FU) derivative combined with oral leucovorin plus weekly intravenous paclitaxel. While the daily oral dose of UFT is fixed at 300 mg/m2 plus 90 mg leucovorin on days 1 to 28, paclitaxel is escalated in 10 mg/m2 steps starting with 50 mg/m2 weekly as a 1-hour infusion. To date, 26 patients with a median age of 57 years have been entered into the protocol and have received a median 2.2 cycles of therapy. Dose level 4 (paclitaxel 80 mg/m2) has been recently completed. Major dose-limiting toxicities were fatigue syndrome (two patients) and diarrhea (five patients). Preliminary responses have been observed in three of 14 currently evaluable patients. This protocol is taking the development of protracted 5-FU administration--given orally as UFT--in combination with paclitaxel one step further, using paclitaxel in a dose-dense, weekly schedule. It is hoped that an active regimen for the outpatient treatment of solid tumors will be developed.

Recombinant granulocyte colony stimulating factor reduces the infectious complications of cytotoxic chemotherapy.

The aim of this study was to determine the usefulness of recombinant human granulocyte colony stimulating factor (r-metHuG-CSF) following conventional chemotherapy for small cell lung cancer. 130 previously untreated patients were randomised to receive either r-metHuG-CSF (230 micrograms/m2) or placebo on days 4-17 following CDE (cyclophosphamide, doxorubicin and etoposide) chemotherapy. Over all cycles, 53% of 64 patients on placebo and only 26% of 65 patients on r-metHuG-CSF had at least one experience of neutropenia with fever defined as a neutrophil count less than 1.0 x 10(9)/l and a temperature > or = 38.2 degrees C (P < 0.002). It resulted in a reduction in the requirement for parenteral antibiotics from 58% in placebo patients compared with 37% in the r-metHuG-CSF group (P < 0.02), and a significant reduction in the incidence of infection-related hospitalisation. Chemotherapy doses were reduced by 15% or more at least once in 61% of the placebo group compared with 29% in the r-metHuG-CSF group (P < 0.001). 47% of the patients treated with placebo and 29% of the patients treated with r-metHuG-CSF experienced at least one cycle with a delay of 2 days or more in the administration of chemotherapy (P < 0.04). r-metHuG-CSF was well tolerated. There were no significant differences between the two groups in terms of response or survival.
