[Show abstract][Hide abstract] ABSTRACT: Primary extracranial and extraspinal meningiomas are very rare tumours, and primary pulmonary ones are even more uncommon. They present as a solitary pulmonary nodule, and most of them are benign, except for three cases. We describe a primitive atypical pulmonary meningioma first suspected of being a metastasis in a patient during follow-up ten years after therapy for breast cancer.
[Show abstract][Hide abstract] ABSTRACT: We have extensively assessed a biweekly regimen of irinotecan plus folinic acid and fluorouracil bolus (IRIFAFU) in metastatic colorectal cancer (MCRC). Here, we report on the safety and activity of BIFF (bevacizumab plus IRIFAFU) regimen in 94 mCRC patients.
Bevacizumab 5 mg/kg (1 hour), and irinotecan 180 mg/m(2) (1 hour) were given intravenously on day 1, 6S-folinic acid 250 mg/m(2) (2 hours), and fluorouracil 850 mg/m(2) (bolus) were given intravenously on day 2 every 2 weeks for a median of 9 cycles per patient (range, 1-12), and maintenance bevacizumab alone was delivered in 16 cases.
Grade ≥ 3 hematologic toxicities were neutropenia (50%) and febrile neutropenia (5%). Most common grade 3 nonhematologic side effects were diarrhea (20%), vomiting (7%), nausea (4%), and stomatitis (4%). Severe hypertension (1%) and epistaxis (1%) rarely occurred. Six complete responses and 44 partial responses were registered, giving a response rate of 53% (95% CI, 43%-64%). Median progression-free survival was 11.5 months (95% CI, 9.0-14.0 months). Forty-three (46%) patients eventually died, and the median overall survival was 24.0 months (95% CI, 20.2-27.8 months).
Bevacizumab appeared to increase the activity of the IRIFAFU regimen without worsening its tolerability. Efficacy of BIFF was comparable with that reported with other bevacizumab plus irinotecan-based combinations.

[Show abstract][Hide abstract] ABSTRACT: To estimate the safety, activity, and impact on quality of life of a combination of gemcitabine and pemetrexed in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) in the context of a randomized two-stage phase II study.
Patients in stage IIIB or IV NSCLC were randomly allocated to receive either gemcitabine 1250 mg/m(2) on day 1, and pemetrexed (Alimta) 500 mg/m(2) followed by gemcitabine 1250 mg/m(2) on day 8 of a 3-weekly cycle (GA arm), or paclitaxel 120 mg/m(2) followed by gemcitabine 1000 mg/m(2), both given on days 1 and 8 of a 3-weekly cycle (PG arm).
105 (GA arm, 51; PG arm, 54) eligible patients (stage IV, 32 and 30, respectively) were enrolled into this study; thereafter, accrual was stopped due to first-stage analysis. The response rate was 20% (95% confidence interval [CI], 10-33%) in the GA arm, and 32% (95% CI, 20-46%) in the PG arm. Median progression-free survival was 5.1 (95% CI, 3.7-6.5) months in the GA arm, and 8.3 (95% CI, 5.9-10.7) months in the PG arm, while median overall survival was 10.5 (95% CI 7.1-13.9), and 13.3 (95% CI 11.7-14.9) months, respectively. Severe neutropenia (36% vs 22%), and febrile neutropenia (14% vs 7%) were more common with the GA regimen, while hair loss (52% vs 16%) and any grade peripheral neuropathy (31% vs 2%) occurred more frequently with PG regimen. Other severe side effects of GA regimen were diarrhoea (10%), liver enzyme derangement (10%), and fatigue (8%).
The GA regimen was tolerated and moderately active in advanced or metastatic NSCLC. However, this combination did not yield any advantage in comparison with the PG regimen, and does not deserve further evaluation.

[Show abstract][Hide abstract] ABSTRACT: This phase II trial assessed the tolerability and efficacy of a triplet of oxaliplatin, irinotecan, and fluorouracil/folinic acid in advanced gastric cancer.
Patients with unresectable or metastatic gastric cancer, unexposed to palliative chemotherapy, received oxaliplatin 85 mg/m(2) iv and irinotecan 150 mg/m(2) iv on day 1, 6S-folinic acid 250 mg/m(2) iv and fluorouracil 750 mg/m(2) iv on day 2, every 2 weeks. Response rate (RR) was assessed after a minimum of four cycles, and treatment continued up to 12 cycles.
Sixty-three patients were treated, with a median of eight (range 1-12) cycles/patient. Two complete and 19 partial responses were registered (RR 33% [95% CI, 22-46%]). Median progression-free survival was 7.5 (95% CI, 5.6-9.4) months, and median overall survival was 12.1 (95% CI, 10.8-13.4) months. Most common grade > or =3 toxicities were neutropenia (59%), febrile neutropenia (7%), vomiting (20%), and diarrhoea (10%). All-grade neurotoxicity affected 33% of patients.
Oxaliplatin, irinotecan, and fluorouracil/folinic acid administered every 2 weeks are safe and active in advanced gastric cancer.

[Show abstract][Hide abstract] ABSTRACT: We evaluated safety and efficacy of PTK787/ZK222584 (PTK/ZK), a novel tyrosine kinase inhibitor of KIT, platelet-derived growth factor receptors and vascular endothelial cell growth factor receptors (VEGFRs), in patients with imatinib-resistant gastrointestinal stromal tumor (GIST). This is the first study of PTK/ZK in this population.
Patients with metastatic GIST that had progressed after >/= 4-week treatment with imatinib mesylate were eligible. Prior VEGFR-2 inhibitor therapy was not permitted. PTK/ZK 1250 mg orally once-daily was administered to 15 patients (accrued as a two-stage procedure), most of whom (n = 11) had been unsuccessfully treated with imatinib 800 mg daily, until treatment failure. Patients were monitored at 4- to 8-week intervals.
All 15 patients enrolled were eligible; two (13%) achieved partial response (PR), eight (53%) had stable disease (SD) >/=3 months, and five (33%) progressed. The clinical benefit rate (PR + SD) was 67% (95% CI 38% to 86%). Median time to progression was 8.5 months (range 0.9-24.8+ months). Three patients had not progressed at the time of analysis, including one PR at 24.8 months and two SDs at 16.6 and 18.6 months on treatment. PTK/ZK was generally well tolerated.
PTK/ZK 1250 mg p.o. once daily is active and well tolerated in patients with imatinib-resistant GIST.

[Show abstract][Hide abstract] ABSTRACT: In a previous phase I dose-escalation study, we showed a weekly administration of paclitaxel (TAX) and gemcitabine (GEM) to be active and very well tolerated in non-small-cell lung cancer (NSCLC) patients, with the lack of interaction between drugs. The dose of GEM 1500 mg/m(2) and TAX 100 mg/m(2) was selected for phase II studies due to its predictable kinetic behaviour and less severe thrombocytopenia.
Fifty-four chemo-naïve patients with advanced NSCLC (53 patients: stage IV) received TAX (100mg/m(2) i.v. infusion over 1h) followed by GEM 1500 mg/m(2) over 30 min) on days 1, 8, 15 and 21 of a 28-day cycle.
The objective response rate was 46% (95% CI 32-61), median OS of 10.4 ms (95% CI 6.5-4.3), and a 1-year survival rate of 53%. Grades 3 and 4 haematological toxicity consisted of non-febrile neutropenia and thrombocytopenia in 13 and 4% of the cycles, respectively. Grade 3 non-haematological toxicities were observed in three patients (asthenia, diarrhoea and neuropathy), and were always reversible.
This weekly schedule of TAX and GEM is highly active in chemo-naïve NSCLC patients and confirms the low toxicity profile already observed in a previous phase I study.

[Show abstract][Hide abstract] ABSTRACT: This study was undertaken to select the best schedule of administration for the paclitaxel plus gemcitabine combination in fit elderly patients affected by locally advanced or metastatic non-small cell lung cancer (NSCLC).
Ninety-eight patients in stage III or IV NSCLC, aged 70 years or more and in ECOG performance status (PS)<or=1, were randomly allocated to receive: paclitaxel 80 mg/m(2) plus gemcitabine 1000 mg/m(2) i.v. on days 1 and 8, with an intra-patient alternated dose escalation up to 100 and 1200 mg/m(2), respectively, over three cycles (arm A); or paclitaxel 80 mg/m(2) followed by gemcitabine 1000 mg/m(2) i.v. (100 min) on days 1 and 8 (arm B). Treatment was repeated in both arms every 3 weeks for a maximum of six cycles.
With a median of 3 (range, 1-6) delivered cycles, the two schedules yielded a similar response rate (25% versus 26%), failure-free survival (median, 3.3 months versus 3.2 months), progression-free survival (median, 5.1 months versus 5.2 months), and overall survival (median, 9.7 months versus 9.6 months). Survival was independently affected by the PS of patients and by the metastatic spread. Severe side effects were comparable and negligible in both arms.
A substantial difference between these two schedules in terms of efficacy and safety can be ruled-out. Paclitaxel plus gemcitabine is an advisable combination for treating fit elderly patients with advanced NSCLC.

[Show abstract][Hide abstract] ABSTRACT: Triplet regimens were occasionally reported to produce a higher response rate (RR) than doublets in locally advanced or metastatic non-small-cell lung cancer (NSCLC). This trial was conducted to assess (i) whether the addition of cisplatin (CDDP) to either gemcitabine (GEM) and vinorelbine (VNR) or GEM and paclitaxel (PTX) significantly prolongs overall survival (OS) and (ii) to compare the toxicity of PTX-containing and VNR-containing combinations.
Stage III or IV NSCLC patients were randomly assigned to (i) GEM 1000 mg/m(2) and VNR 25 mg/m(2) on days 1 and 8 (GV arm); (ii) GEM 1000 mg/m(2) and PTX 125 mg/m(2) on days 1 and 8 (GT arm); (iii) GV plus CDDP 50 mg/m(2) on days 1 and 8 (PGV arm); and (iv) GT plus CDDP 50 mg/m(2) on days 1 and 8 (PGT arm). Treatments were repeated every 3 weeks for a maximum of six cycles.
A total of 433 (stage III, 160; stage IV, 273) patients were randomly allocated to the study. RR was 48% [95% confidence interval (CI), 42% to 54%] for triplets and 35% (95% CI, 32% to 38%) for doublets (P = 0.004). Median progression-free survival (6.1 versus 5.5 months, P = 0.706) and median OS (10.7 versus 10.5 months, P = 0.379) were similar. CDDP significantly increased the occurrence of severe neutropenia (35% versus 13%), thrombocytopenia (14% versus 4%), anaemia (9% versus 3%), vomiting (6% versus 0.5%), and diarrhoea (6% versus 2%). Conversely, frequency of severe neutropenia (30% versus 17%) and thrombocytopenia (11% versus 6%) was significantly higher with VNR-containing regimens.
Adding CDDP to GV or GT significantly increased RR, but did not prolong the OS of patients. Among doublets, the GT regimen should be preferred in view of its better safety profile.

[Show abstract][Hide abstract] ABSTRACT: We have assessed the survival rate of patients with non-small cell lung cancer and synchronous hematogenous solitary metastasis identified with complete staging workup, including total body [18F]fluorodeoxyglucose positron emission tomography scan, and treated with a multidisciplinary approach.
We examined the database of all patients who underwent surgery for primary non-small cell lung cancer in our institute. The criteria required for inclusion in this analysis were diagnosis of non-small cell lung cancer with synchronous hematogenous solitary metastasis by staging workup with total body computed tomography scan and brain magnetic resonance if indicated, total body positron emission tomography scan, radical surgery for the primary tumors, local treatment of the solitary metastasis, and systemic chemotherapy administration.
We analyzed the data from 1,509 patients treated from January 2000 to December 2005: 10 patients (0.7%) satisfied the selection criteria. The median overall survival was 26 months, and the median time to progression was 20 months; 6 patients were alive at the time of analysis, with a median follow-up of 30 months. Four patients were tumor progression-free after 9, 18, 23, and 32 months from the start of their treatment.
The presentation of non-small cell lung cancer with a synchronous hematogenous solitary metastasis identified by [18F]fluorodeoxyglucose positron emission tomography containing complete staging workup is extremely rare. This subset of patients can achieve long-term survival after a multidisciplinary treatment approach.

[Show abstract][Hide abstract] ABSTRACT: Oxaliplatin (OXA) and irinotecan (IRI) are active drugs for metastatic colorectal cancer, their toxicity profiles are not overlapping, and both drugs have shown at least additivity with folinic acid-modulated 5-fluorouracil (5FU). We carried out this phase II study to assess the activity and toxicity of a biweekly regimen including OXA plus IRI on day 1, and levo-folinic acid (LFA) plus 5FU on day 2 (OXIRIFAFU) in pretreated patients with metastatic colorectal cancer. Forty-one patients, all previously treated with adjuvant and/or palliative 5FU-based chemotherapy (16 of them already exposed to IRI, OXA or both), were enrolled into this trial. On the basis of sensitivity to previous treatment, 19 patients were considered as chemo-resistant and 14 patients as chemo-refractory. OXA 110 mg/m (over 2 h) and IRI 175 mg/m (over 1 h) were delivered on day 1, followed by LFA 250 mg/m (2-h infusion) plus 5FU 800 mg/m as intravenous bolus on day 2. Cycles were repeated every 2 weeks. A total of 348 cycles were delivered, with a median of nine cycles per patient (range, 1-12 cycles per patient). Five complete and 13 partial responses were reported on 40 assessable patients, giving a response rate of 45% [95% confidence interval (CI), 29-62%]; eight of 19 (42%) resistant patients and five of 14 (36%) refractory patients achieved a major response, which was also obtained in four of eight (50%) patients pretreated with IRI and in three of eight (38%) patients pretreated with OXA. Grade 3 or higher neutropenia occurred in 68% of patients, but febrile neutropenia or infections affected only seven (17%) patients. No episodes of grade 3 or higher thrombocytopenia or anemia were recorded. Occurrence of severe non-hematologic toxicities by patients were: diarrhea, 34%; vomiting, 17%; peripheral cumulative neuropathy, 15%; stomatitis, 10%; acute cholinergic syndrome, 7%. Actually delivered dose intensities of all three drugs resulted in about two-thirds of the planned ones. After a follow-up of 39 months, median progression-free survival was 7.5 months. Median overall survival was 14.4 (95% CI, 10.4-18.4) months from the start of OXIRIFAFU and 25.3 (95% CI, 18.1-32.5) months from the diagnosis of metastatic disease. This OXIRIFAFU triplet regimen was highly effective in resistant/refractory colorectal cancer patients. A slight dose reduction of all cytotoxic drugs could be advisable in order to improve the tolerability of this regimen without jeopardizing its activity.
