    Abstract: To evaluate long-term survival in a prospective series of patients newly diagnosed with glioblastoma and treated with a combination of lomustine (CCNU), temozolomide (TMZ), and radiotherapy. Patients and Methods Thirty-nine patients received radiotherapy of the tumor site only (60 Gy) and CCNU/TMZ chemotherapy (n = 31 received standard-dose CCNU, 100 mg/m 2 on day 1 and TMZ 100 mg/m 2 /d on days 2 to 6; n = 8 received intensified-dose CCNU 110 mg/m 2 on day 1 and TMZ 150 mg/m 2 on days 2 to 6) for up to six courses. Results In the whole cohort, the median overall survival (mOS) was 23.1 months; 47.4% survived for 2 years, and 18.5% survived for 4 years. After a median follow-up of 41.5 months, mOS had not been reached in the intensified group and was significantly higher than in the standard group (22.6 months; P = .024). In the intensified group, four of eight patients survived for at least 56 months, two of them without recurrence. O 6 -methylguanine–DNA methyltransferase (MGMT) gene promotor methylation in the tumor tissue was associated with significantly longer mOS (methylated, 34.3 months v nonmethylated, 12.5 months). A multivariate Cox proportional hazard model revealed MGMT status (methylated v nonmethylated; relative risk [RR] of death, 0.43; P = .003) and chemotherapy dose (intensified v standard; RR, 0.37; P = .012) as independent prognostic factors. WHO grade 4 hematoxicity was observed more frequently in the intensified group (57% v 16%). Conclusion The combination of radiotherapy, CCNU, and TMZ yielded promising long-term survival data in patients with newly diagnosed glioblastoma. Intensification of CCNU/TMZ chemotherapy may add an additional survival benefit, albeit with greater acute toxicity.

    Assessment of Disease Dissemination in Gastric Compared With Extragastric Mucosa-Associated Lymphoid Tissue Lymphoma Using Extensive Staging: A Single-Center Experience
    American Society of Clinical Oncology (ASCO) ; 2006

    Abstract: Molecular data and preliminary clinical findings have suggested mucosa-associated lymphoid tissue (MALT) lymphoma as a multifocal disease in a high percentage of patients. We report our findings with an extensive staging routine applied in patients diagnosed with MALT lymphoma at our institution. Patients and Methods A total of 140 consecutive patients (61 with gastric and 79 with extragastric MALT lymphoma) underwent staging according to a standardized protocol. Staging included gastroscopy with multiple biopsies, endosonography of the upper GI tract, computed tomography of thorax and abdomen, lymph node sonography, colonoscopy with multiple biopsies, otorhinolaryngologic assessment, magnetic resonance imaging of salivary and lacrimal glands, and bone marrow biopsy. All lesions suggestive of lymphoma involvement were subjected to biopsy, if accessible, and biopsies were evaluated for MALT lymphoma–specific genetic aberrations by means of reverse transcriptase polymerase chain reaction and/or fluorescent in situ hybridization. Results Fifteen (25%) of 61 patients with gastric MALT lymphoma had multiorgan involvement, with dissemination beyond the GI tract in six patients. By contrast, significantly more patients with extragastric MALT lymphoma had dissemination to another MALT organ (37 of 79 patients, 46%; P = .045). Nine of these 37 patients had dissemination to the stomach. Only three (2%) of 140 patients had bone marrow involvement. Multifocality was significantly associated with t(11;18)(q21;q21) in gastric lymphomas (P = .045) and with trisomy 18 in extragastric lymphomas (P = .011). Conclusion Our findings suggest that MALT lymphoma frequently presents as a multifocal disease. Extragastric MALT lymphomas are significantly more prone to dissemination than gastric MALT lymphomas.

    Phase II Study of Oxaliplatin for Treatment of Patients With Mucosa-Associated Lymphoid Tissue Lymphoma

    Abstract: Various chemotherapeutic regimens have been applied for treatment of mucosa-associated lymphoid tissue (MALT) lymphoma, but no standard regimen has been identified to date. In view of the activity of oxaliplatin (L-OHP) in various types of lymphoma, we performed a phase II study to evaluate the activity of L-OHP for treatment of MALT lymphoma. The primary objective of this study was to determine the objective response rate according to WHO standard criteria. Patients and Methods A total of 16 patients with MALT lymphoma of various sites of origin (four of the ocular adnexa, five of the salivary glands, three of the stomach, two of the lung, and one of the colon and the breast) were administered L-OHP at a dose of 130 mg/m 2 infused during 2 hours every 3 weeks. Restaging was performed every two cycles; treatment was continued until complete remission (CR) or for a maximum of six cycles in responders. Results Sixty-five cycles were administered (median, four; range, two to six); toxicity consisted of transient sensory neuropathy in eight patients and nausea/emesis WHO grade 2 in two patients, whereas hematologic adverse effects (thrombocytopenia and leukocytopenia grade 2) occurred in only one patient each. Fifteen patients responded to chemotherapy, with nine achieving CR (56%), six (37.5%) achieving partial response, and one achieving stable disease; the median time to response was 4 months (range; 2 to 4 months). Conclusion These data suggest L-OHP is a highly active agent for treatment of MALT lymphoma. However, a longer follow-up is needed to judge whether these remissions are durable.

    Abstract: To evaluate toxicity and efficacy of the combination of lomustine, temozolomide (TMZ) and involved-field radiotherapy in patients with newly diagnosed glioblastoma (GBM). Patients and Methods Thirty-one adult patients (median Karnofsky performance score 90; median age, 51 years) accrued in two centers received involved-field radiotherapy (60 Gy in 2-Gy fractions) and chemotherapy with lomustine 100 mg/m 2 (day 1) and TMZ 100 mg/m 2 /d (days 2 to 6) with individual dose adjustments according to hematologic toxicity. Results A median of five courses (range, one to six courses) were delivered. WHO grade 4 hematotoxicity was observed in five patients (16%) and one of these patients died as a result of septicemia. Nonhematologic toxicity included one patient with WHO grade 4 drug-induced hepatitis (leading to discontinuation of lomustine and TMZ) and one patient with WHO grade 2 lung fibrosis (leading to discontinuation of lomustine). The progression-free survival (PFS) rate at 6 months was 61.3%. The median PFS was 9 months (95% CI, 5.3 to 11.7 months), the median overall survival time (MST) was 22.6 months (95% CI, 12.5 to not assessable), the 2-year survival rate was 44.7%. O 6 -Methylguanine–DNA methyltransferase (MGMT) gene-promoter methylation in the tumor tissue was associated with longer PFS (P = .014, log-rank test) and MST (P = .037). Conclusion The combination of lomustine, TMZ, and radiotherapy had acceptable toxicity and yielded promising survival data in patients with newly diagnosed GBM. MGMT gene-promoter methylation was a strong predictor of survival.
