[Epoietin alfa in lung cancer].

There is a high frequency of hematopoietic abnormalities in patients with neoplastic disorders, anemia being one of the most common and important, especially in lung cancer patients undergoing chemotherapy. A number of factors are able to affect the incidence and severity of chemotherapy-induced anemia: the type of chemotherapy, chemotherapy dose-intensity, chemotherapy duration, prior treatment, baseline Hb value and entity of Hb decrease during chemotherapy. An impaired erythroid marrow response to erythropoietin (EPO) and reduced EPO levels in response to anemia may contribute to the development of this form of anemia in lung cancer patients. Recombinant human EPO has been successfully used in the treatment of anemia. EPO increases the red cells mass and eliminates by approximately 50% the need for blood transfusions in patients with chronic anemia of cancer. EPO is also effective in the prevention of anemia of cancer patients. Besides increasing the levels of hemoglobin, EPO is also able to significantly improve the quality of life and performance status of anemic patients with cancer. EPO is well tolerated and the only drawbacks are represented by its cost and the need for a prolonged parenteral treatment. The use of EPO can be optimized by taking into consideration some predicting factors, by modulating the dose and by using iron support. In patients with lung cancer, the objective of EPO treatment may vary from palliation to survival improvement according to stage, type of antineoplastic treatment and prognosis. To take maximum advantage from its efficacy, EPO treatment in lung cancer patients needs to be individualized by identifying for each patient the risk of severe anemia and the objective of treatment.

The role of vindesine and lonidamine in the treatment of elderly patients with advanced non-small cell lung cancer: a phase III randomized FONICAP trial. Italian Lung Cancer Task Force.

AIMS: To evaluate the efficacy and treatment compliance in elderly patients with advanced non-small cell lung cancer (NSCLC) of two chemotherapeutic agents with mild toxicity, 153 previously untreated patients aged over 70 years were randomized to receive lonidamine (450 mg daily p.o. until progression), vindesine (3 mg/m2/daily i.v. weekly for 4 weeks and then every 2 weeks until progression), the combination of the two drugs at the same dose and schedule, or supportive therapy only in a four-arm factorial randomized trial. METHODS: 126 patients were included in the final analysis. Their median age was 75 years. Forty percent had stage IV disease and 60% stage III. Most patients were males (85%) and the majority had squamous histology (68%). RESULTS: Among 104 patients evaluable for response there were only 3 PRs (1/30 in the lonidamine arm and 2/33 in the lonidamine + vindesine arm). Overall, 8.7% and 9.5% of the patients, respectively, progressed or died early, before response evaluation; another 9.4% refused treatment continuation because of poor compliance with the study protocol. Eighty-five patients were fully evaluable for toxicity, which was generally mild. Leukopenia grade 1-3 was found in less than 30% of patients treated with vindesine or vindesine + lonidamine. The most common complaints associated with lonidamine treatment were myalgia (70% of patients), fatigue (55% and 83% of patients treated with lonidamine or lonidamine + vindesine, respectively) and testicular pain in nearly 40% of cases. The overall median survival was 170 days, with no significant impact on survival of either lonidamine or vindesine. CONCLUSIONS: The low response rate and survival together with the poor treatment compliance, even in the presence of mild toxicity, do not support the usefulness of these "gentle" chemotherapies in elderly NSCLC patients. The standard management of advanced NSCLC in elderly patients remains to be defined. Specifically designed studies to address this issue are warranted.

Phase II study of neoadjuvant chemotherapy in patients with surgically-proven, unresectable stage III non-small cell lung cancer.

BACKGROUND: The aim of this study was to assess whether patients with truly unresectable (bulky extracapsular N2, T4 for tracheobronchial angle or mediastinal organ invasion) stage III non-small cell lung cancer (NSCLC), as proven by cervical mediastinoscopy supplemented or not by left anterior mediastinoscopy and fiberoptic bronchoscopy or thoracotomy, could become resectable after induction cisplatin-containing chemotherapy. In addition, we studied the value of preoperatory magnetic resonance imaging (MRI), in evaluating the probability of achieving a radical resection after neoadjuvant chemotherapy. PATIENTS AND METHODS: Sixteen consecutive untreated stage III NSCLC patients were enrolled in the study. All the patients received two cycles of combination chemotherapy including cisplatin 100-120 mg/m2 intravenously (i.v.) days 1 and 22 and vinorelbine 30 mg/m2 i.v. days 1, 8, 15, 22 and 28 or vinblastine 5 mg/m2 i.v. days 1, 8, 15, 22 and 28. Thoracotomy was planned, after chemotherapy, for all non-progressive patients. No other treatment after surgery was devised following radical resection and patients with residual disease after surgery received standard post-operative radiotherapy. Response to treatment was evaluated by thorax CT and MRI two weeks after the last administration of chemotherapy. RESULTS: The overall complete resection rate was 38% (6 out of 16 patients). MRI was predictive of complete resectability in 80% of cases. In fact, 6 patients judged resectable were completely resected, 3 patients judged unresectable underwent only explorative thoracotomy or incomplete resection while MRI was unpredictive only in one case. The most important chemotherapy-related toxicity was hematological: eight patients (50%) had grades III-IV leukopenia. CONCLUSION: These results indicate that preoperative second generation cisplatin-based chemotherapy can make resectable truly unresectable stage III NSCLC patients in only 38% of cases and that MRI is a reliable tool for assessment of radical resection probability after neoadjuvant chemotherapy.

Malignant mesothelioma in 2004: How advanced technology and new drugs are changing the perspectives of mesothelioma patients. Highlights from the VIIth Meeting of the International Mesothelioma Interest Group.

Malignant mesothelioma (MMe) is a seemingly uncommon tumour whose incidence has in fact increased steadily and progressively over the last 30 years. Indeed, an actual "epidemic" is expected in the next 20 years, with over 1300 new cases a year till 2020 at least. Despite unquestionable improvement in the diagnostic methods at our disposal and the availability of new treatment strategies, the prognosis of MMe patients remains dramatically poor. For all the above reasons, translational research is the key to success; indeed, ever increasing knowledge of the molecular mechanisms underlying MMe pathogenesis could lead (and is actually leading) to new, hopefully more active, treatment options. To foster discussion among investigators working in this field, and to exchange different viewpoints concerning the newest advances in MMe pathogenesis and treatment, the VII International Mesothelioma Interest Group (IMIG) meeting was held in Brescia (Italy) between 24 and 26 June 2004 in cooperation with the Italian Group for the Study and Therapy of MMe (GIMe). The aim of this report is to summarize the most significant advances in the different disciplines applied to MMe presented and discussed during the IMIG meeting and how these advances will be changing the perspective of patients with MMe.

Alternating chemotherapy with cyclophosphamide, doxorubicin, vincristine and cisplatin, etoposide followed by prophylactic cranial and thoracic irradiation for small cell lung cancer (SCLC): long-term results.

Both CAV (Cyclophosphamide, Doxorubicin, Vincristine) and PE (Cisplatin, Etoposide) are effective and non cross-resistant regimens in the treatment of SCLC. We designed a chemotherapeutic scheme including CAV and PE given in an alternating fashion with the following schedule: Cyclophosphamide 1000 mg/sm, Doxorubicin 50 mg/sm, Vincristine 2 mg/sm I.V. on day 1, alternated every 21 days with Cisplatin 20 mg/sm and Etoposide 80 mg/sm I.V. days 1-5 for 6 cycles. Following chemotherapy (CT) chest radiotherapy in patients (pts) with limited disease (LD) in complete response (CR) or partial response (PR) and prophylactic cranial irradiation (PCI) in CRs were given, 32 pts entered the study and 27 were evaluable: 9/27 (33.3%) had CR (8/15 with LD had CR) and 15/27 (55.5%) PR. The overall median survival was 53.71 weeks: 79.85 weeks for LD pts and 32.86 for ED.4 pts with LD were alive after 2 years and 2 of them are still alive without disease at 44 and 46 months. Toxicity was acceptable in all patients. Alternating chemotherapy with CAV and PE followed by chest and brain RT in responding LD pts is an effective induction treatment for SCLC although long-term survival still remains disappointing.

Oral chemotherapy for poor risk small-cell lung cancer patients with combined idarubicin and etoposide.

Sixteen patients with previously untreated small-cell lung cancer, unsuitable for standard aggressive intravenous chemotherapy due to advanced age or poor performance status or very advanced disease including brain metastases or either extensive liver or marrow involvement with impaired organ function, were treated with combined oral chemotherapy including 4-demethoxydaunorubicin (IMI30, idarubicin) 30 mg/sm on day 1 and etoposide (VP16) 150 mg/sm on days 2,3,4 every 4 weeks. Out of 13 evaluable patients 1 had a complete response and 2 had a partial response with an overall objective response rate of 23% (95% confidence-limits 5-53.8%). Toxicity was generally very mild. Although the compliance of this regimen is excellent, its antitumor activity seems unsatisfactory even in this category of poor-risk small-cell lung cancer patients.

Recombinant alpha interferon in the treatment of low-grade non-Hodgkin's lymphoma: results of a cooperative phase II trial in 31 patients.

Thirty-one patients with advanced stage of favorable histology non-Hodgkin's lymphomas were entered into a multicenter phase II trial with recombinant alpha A interferon as single agent. Interferon was administered intramuscular in doses of 6 x 10(6)/IU/m2 three times per week for 12 weeks. Dose escalation was applied, in the absence of toxicities greater than WHO grade II, in patients not responding after 4 weeks. In responding patients treatment was continued at the same dose with a weekly maintenance schedule for 12 additional weeks. Objective responses (4 complete, 10 partial) were obtained in 14 of the 27 evaluable patients (52%). Median time to progression was 15 months for partial responders, while none of the complete responders has relapsed up to the present time. Toxicity was generally moderate and manageable. Treatment was discontinued in three patients because of side effects, and one patient refused therapy after 3 weeks. Our study shows that recombinant alpha A interferon has antitumor activity in patients with favorable histology non-Hodgkin's lymphoma.

Malignant pleural mesothelioma. Multivariate analysis of prognostic factors on 113 patients.

We report on clinical features of 113 cases of pathologically confirmed Malignant Pleural Mesothelioma, observed in Genoa (Italy) between 1979 and 1985. Overall median survival was 10 months. Among the pretreatment variables studied (age, sex, asbestos exposure, pathological type, chest pain and dyspnea at the time of diagnosis), the only one of prognostic value in the univariate analysis was the histological subtype: median survivals were 12, 7 and 4 months for the patients in the epithelial, mixed, and fibrosarcomatous groups, respectively (p = 0.0012). A multivariate analysis confirmed the independent predictive power of the histotype (p = 0.0022). A review of literature data concerning prognostic factors in Malignant Pleural Mesothelioma is presented.
