Ophelimus mediterraneus sp. n. (Hymenoptera, Eulophidae): a new Eucalyptus gall wasp in the Mediterranean region.

We report here for the first time the presence of Ophelimus mediterraneus sp. n. in Mediterranean Europe. This species appears to be closely related to Ophelimus maskelli, a well-known invasive pest of Eucalyptus. Based on molecular (cytochrome oxidase I, 28S), morphological (multivariate ratio analysis) and bio-ecological investigations, our study gives unambiguous relevant criteria that allow the discrimination between these two species. A full description of O. mediterraneus sp. n. is also provided. The geographic distribution of O. mediterraneus sp. n. as well as its impact on Eucalyptus species needs to be more widely assessed since its presence may have been confused with O. maskelli in their sympatric introduced areas. Further investigations of potential parasitoids in the native area may thus be welcomed to evaluate classical biological control achievability.

A randomised clinical trial of two docetaxel regimens (weekly vs 3 week) in the second-line treatment of non-small-cell lung cancer. The DISTAL 01 study.

Docetaxel (75 mg m(-2) 3-weekly) is standard second-line treatment in advanced non-small-cell lung cancer (NSCLC) with significant toxicity. To verify whether a weekly schedule (33.3 mg m(-2) for 6 weeks) improved quality of life (QoL), a phase III study was performed with 220 advanced NSCLC patients, < or =75 years, ECOG PS < or =2. QoL was assessed by EORTC questionnaires and the Daily Diary Card (DDC). No difference was found in global QoL scores at 3 weeks. Pain, cough and hair loss significantly favoured the weekly schedule, while diarrhoea was worse. DDC analysis showed that loss of appetite and overall condition were significantly worse in the 3-week arm in the first week, while nausea and loss of appetite were more severe in the weekly arm in the third week. Response rate and survival were similar, hazard ratio of death in the weekly arm being 1.04 (95% CI 0.77-1.39). A 3-weekly docetaxel was more toxic for leukopenia, neutropenia, febrile neutropenia and hair loss; any grade 3-4 haematologic toxicity was significantly more frequent in the standard arm (25 vs 6%). The weekly schedule could be preferred for patients candidate to receive docetaxel as second-line treatment for advanced NSCLC, because of some QoL advantages, lower toxicity and no evidence of strikingly different effect on survival.

Prevalence and management of pain in Italian patients with advanced non-small-cell lung cancer.

Pain is a highly distressing symptom for patients with advanced cancer. WHO analgesic ladder is widely accepted as a guideline for its treatment. Our aim was to describe pain prevalence among patients diagnosed with advanced non-small-cell lung cancer (NSCLC), impact of pain on quality of life (QoL) and adequacy of pain management. Data of 1021 Italian patients enrolled in three randomised trials of chemotherapy for NSCLC were pooled. QoL was assessed by EORTC QLQ-C30 and LC-13. Analgesic consumption during the 3 weeks following QoL assessment was recorded. Adequacy of pain management was evaluated by the Pain Management Index (PMI). Some pain was reported by 74% of patients (42% mild, 24% moderate and 7% severe); 50% stated pain was affecting daily activities (30% a little, 16% quite a bit, 3% very much). Bone metastases strongly affected presence of pain. Mean global QoL linearly decreased from 64.9 to 36.4 from patients without pain to those with severe pain (P<0.001). According to PMI, 616 out of 752 patients reporting pain (82%) received inadequate analgesic treatment. Bone metastases were associated with improved adequacy and worst pain with reduced adequacy at multivariate analysis. In conclusion, pain is common in patients with advanced NSCLC, significantly affects QoL, and is frequently undertreated. We recommend that: (i). pain self-assessment should be part of oncological clinical practice; (ii). pain control should be a primary goal in clinical practice and in clinical trials; (iii). physicians should receive more training in pain management; (iv). analgesic treatment deserves greater attention in protocols of anticancer treatment.

Carboplatin + epirubicin +VP-16 + lenograstim followed by radiotherapy + carboplatin as radiosensitizer in limited small cell lung cancer. A multicenter phase II study.

UNLABELLED: A phase II trial was undertaken to test the activity and toxicity of carboplatin (300 mg/m2, i.v. day 1) + epirubicin (75 mg/m2, i.v. day 1) + VP-16 (100 mg/m2, i.v. days 1 to 3) + lenograstim (5 mcg/kg, s.c. days 6 to 15) administered every 3 weeks for 4 cycles and subsequent chest irradiation (50 Gy) + daily carboplatin (25 mg/m2) in the first-line treatment of adults affected by limited small cell lung cancer (SCLC). PATIENTS AND METHODS: A single-stage phase II design was used; the complete response (CR) rate after chest radiotherapy was the primary end-point. Twenty-three CRs were required out of 38 patients to consider the treatment worthy of further study. Prophylactic cranial irradiation (PCI) was planned in case of CR. Patients aged < or = 70 were eligible if they had limited SCLC, a performance status not worse than 2 by the ECOG scale and no prior chemotherapy or radiotherapy. RESULTS: From January 1995 to April 1999, 33 patients were enrolled; the median age was 60 years. All the patients started chemotherapy; 23 patients received chest irradiation and concurrent daily carboplatin; 11 patients also received PCI. Toxicity was generally mild. Sixteen CRs (48.5%, 95% CI: 30.8-66.5) were recorded; the objective response rate was 72.7% (95% CI: 54.5-86.7). The median time-to-progression was 7.9 months (95% CI: 6.5-10.4). The median-survival was 10.7 months (95% CI: 9.2-16.1). CONCLUSION: Induction chemotherapy with carboplatin + epirubicin + VP-16 followed by chest irradiation plus concurrent daily carboplatin is well-tolerated but not sufficiently active to warrant further study in the treatment of patients with limited SCLC.

Amifostine plus cisplatin plus vinorelbine in the treatment of advanced non small cell lung cancer: a multicenter phase II study.

PURPOSE: to evaluate the activity and toxicity of the combination cisplatin plus vinorelbine plus amifostine in advanced non small cell lung cancer (NSCLC). PATIENTS AND METHODS: a two-stage Simon design was applied. To proceed after the first stage, responses from seven of 19 patients were needed. Overall, 17 responses from 40 treated patients were required to comply with the design parameter. Inclusion criteria were cyto-histologically proven stage IIIB-IV NSCLC; age of 70 years or less; Eastern Cooperative Oncology Group (ECOG) performance status of 2 or less; normal cardiac, hepatic, renal and bone marrow functions; and no previous chemotherapy. Patients were staged by physical examination, biochemistry, chest radiograph, brain, thoracic and abdominal computed tomographic (CT) scans, and bone scan. All patients received cisplatin 100 mg/m(2) intravenously (iv) day 1, vinorelbine 25 mg/m(2) iv days 1-8-15-22, amifostine 740 mg/m(2) iv day 1 every 4 weeks up to six cycles. Eleven of 40 enrolled patients were stage IIIB and 29 stage IV, with a median age of 57 years (range, 38-70 years). RESULTS: all patients were evaluable for response and toxicity (intention to treat analysis). We observed 20 (50%) objective responses, with four (10%) complete responses. Median time to progression was 20 weeks, and median survival was 45 weeks. The toxicity was manageable. The reported main toxicities were neutropenia grade 4 in 10% of patients, grade 1 and grade 3 nephrotoxicity both in 5% of patients and grade 1 amifostine-related hypotension in 15% of patients. CONCLUSION: these data show that cisplatin plus vinorelbine plus amifostine is an active and feaseable regimen in stage IIIB-IV NSCLC. A phase III trial comparing cisplatin plus vinorelbine versus cisplatin plus vinorelbine plus amifostine in advanced NSCLC is warranted.

Carboplatin plus vinorelbine, a new well-tolerated and active regimen for the treatment of extensive-stage small-cell lung cancer: a phase II study. Gruppo Oncologico Centro-Sud-Isole.

PURPOSE: To evaluate the activity and toxicity of the combination carboplatin plus vinorelbine in extensive small-cell lung cancer (SCLC). PATIENTS AND METHODS: A two-stage optimal Simon design was applied. To proceed after the first stage, responses from 8 of 11 treated patients were needed. Overall, 31 responses of 43 treated patients were required to comply with the design parameters. Inclusion criteria were cytohistologically proven SCLC; extensive disease; age of 70 years or less; Eastern Cooperative Oncology group performance status (ps ECOG) of 2 or less; normal cardiac, hepatic, renal, and bone marrow functions; and no previous chemotherapy. Patients were staged by physical examination; biochemistry; chest radiograph; brain, thoracic; and abdominal computed tomographic (CT) scans, and bone scan. All patients received carboplatin 300 mg/m2 intravenously (i.v.) day 1 and vinorelbine 25 mg/m2 i.v. on days 1 and 8 every 4 weeks up to six cycles. Of 43 enrolled patients, 36 were men and 7 women, with a median age of 63 years (range, 46 to 70 years). RESULTS: All patients were assessable for response and toxicity. We observed 32 (74%) objective responses, with 23% complete responses. Median time to progression was 25 weeks, and median survival was 37 weeks. The treatment was well tolerated. The reported main toxicities were leukopenia grade 3 in 21% of patients and grade 4 in 5% of patients, anemia grade 2 in 11% of patients and grade 3 in 2% of patients, and thrombocytopenia grade 3 in 7% of patients. CONCLUSION: These data show that carboplatin plus vinorelbine is an active and well-tolerated regimen in extensive SCLC. In view of the activity, low toxicity, and ease of administration, it may be a reasonable alternative to more toxic cisplatin-containing regimens.

Cisplatin, epirubicin, and vindesine with or without lonidamine in the treatment of inoperable nonsmall cell lung carcinoma: a multicenter randomized clinical trial.

BACKGROUND: Lonidamine (LND) is an indazol-carboxylic acid derivative that selectively inhibits the energy metabolism of neoplastic cells, and increases the permeability of cell membranes. In vitro studies have demonstrated that LND can potentiate the oncolytic activity of cytotoxic drugs and is able to reverse the acquired multidrug resistance of neoplastic cells. Some clinical trials have suggested a synergism of LND with alkylating agents, cisplatin, and anthracyclines in various solid tumors. METHODS: From June 1990 to June 1993, 158 previously untreated patients with Stage IIIB and IV nonsmall cell lung cancer (NSCLC) were enrolled into a multicentric randomized trial to evaluate the addition of LND to a cisplatin-epirubicin-vindesine regimen. Eighty patients in the control arm (A) received cisplatin, 60 mg/m2 intravenously (i.v.); epirubicin, 60 mg/m2 i.v.; and vindesine, 3 mg/m2 i.v. (PEV), on Day 1 every 4 weeks, whereas 78 patients in the experimental arm (B) received the same regimen with the addition of LND from 75 mg orally three times on Day 1 to 150 mg orally three times on Day 7+ until tumor progression occurred. RESULTS: The experimental treatment achieved a significantly higher proportion of major responses in comparison with the control regimen (43% vs. 24%; P=0.02). The addition of LND apparently potentiated the activity of this cytotoxic treatment, particularly in patients with metastatic disease (overall response rate, 39% vs. 17%). The median time to progression (5 vs. 8 months; P=0.0007) and the median survival time (7.6 vs. 11 months; P=0.0013) were also statistically improved in Arm B. The acute toxicity of the 2 treatments was low: only 6% of patients in Arm A and 4% of patients in Arm B had to withdraw from treatment due to Grade 4 World Health Organization toxicity. The main additional side effects related to the administration of LND were epigastralgia, myalgia, asthenia, and orchialgia. However, these symptoms were mild and controlled by the concomitant administration of low doses of steroids. CONCLUSIONS: The mild acute toxicity of the PEV regimen and the acceptable and nonoverlapping additional side effects of LND render our experimental therapy worthy of consideration for the management of NSCLC patients with poor performance status or low tolerance to more aggressive therapeutic approaches.

Carboplatin plus epirubicin plus VP-16, concurrent 'split course' radiotherapy and adjuvant surgery for limited small cell lung cancer. Gruppo Oncologico Centro-Sud-Isole (GOCSI).

Thirty-three patients with limited small cell lung cancer (SCLC) received carboplatin, epirubicin and VP-16 chemotherapy, concurrent 'split course' thoracic radiotherapy, followed by surgery for patients achieving an objective response (OR). High-risk patients and those staged T4-N3 (IIIB) at diagnosis, were excluded from surgery. After induction chemoradiotherapy we obtained 90.9% OR, with 63.3% obtaining complete response (CR). Ten patients (30.3%) were eligible for surgery after induction therapy. Five patients (15.1%) were subjected to surgery and five additional patients refused. Of the five patients who were subjected to surgery, four had a complete response (CR), (three pathological confirmations), and one had a partial response (PR), (unresectable). The median survival time for all patients was 16 months with 12.1% of the long-term survivors still living after 2 years and 9% still living after 3 and 4 years. Toxicity consisted mainly of myelosuppression. This study shows a high activity of the chemotherapy and the chemoradiotherapeutic regimen employed but a low feasibility for adjuvant surgery in SCLC.

Carboplatin, epirubicin, and VP-16 chemotherapy in the treatment of small cell lung cancer.

In our study, 72 SCLC patients, 23 with limited and 49 with extensive disease, were treated with carboplatin, epirubicin, and VP-16 (CEV) chemotherapy (CBDCA 300 mg/m2 day 1, EDX 50 mg/m2 day 1, VP-16 100 mg/m2 i.v. days 1-3, every 4 weeks). Patients with limited disease were also subjected to concurrent "split-course" chest radiotherapy followed by surgery in responders if they were not staged IIIB at diagnosis. In limited disease we obtained 96.5% objective responses (OR) with 52.5% complete responses (CR), a median survival of 14 months, with 13% long-term survivors at 30 months. In extensive disease we obtained 83.6% OR with 28.5% CR, and a median survival of 10 months. Toxicity consisted mainly of manageable myelosuppression, especially for limited disease. These data show high activity of CEV chemotherapeutic regimen.
