Background: In this study several tumor-related volumes were assessed by means of a computer-based application and a survival analysis was conducted to evaluate the prognostic significance of pre- and postoperative volumetric data in patients harboring glioblastomas. In addition, MGMT (O6-methylguanine methyltransferase) related parameters were compared with those of volumetry in order to observe possible relevance of this molecule in tumor development.

Methods: We prospectively analyzed 65 patients suffering from glioblastoma (GBM) who underwent radiotherapy with concomitant adjuvant temozolomide.

The anti-epidermal growth factor receptor antibody cetuximab (Erbitux, CTX) is currently used for the treatment of locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN), as yet with modest effectiveness, prompting for the identification of response predictors to this treatment and for the targeting of additional pathways implicated in this disease. Within this scope, we investigated the effect of SRC/STAT pathway components on LA-SCCHN patient outcome. SRC, STAT1, STAT3, STAT5A, STAT5B, ANXA1, CAV1, IGFBP2, EPHA2, EPHB2, and MSN relative gene expression, as well as Stat protein activation, were assessed on LA-SCCHN tumor tissues from 35 patients treated with combined radiotherapy (RT) and CTX-based regimens.

Concomitant administration of radiotherapy with cisplatin or radiotherapy with cetuximab appear to be the treatment of choice for patients with locally advanced head and neck cancer. In the present retrospective analysis, we investigated the predictive role of several biomarkers in an unselected cohort of patients treated with concomitant radiotherapy, weekly cisplatin, and cetuximab (CCRT). We identified 37 patients treated with this approach, of which 13 (35%) achieved a complete response and 10 (27%) achieved a partial response.

Background And Purpose: The importance of tumor volume as a prognostic factor in high-grade gliomas is highly controversial and there are numerous methods estimating this parameter. In this study, a computer-based application was used in order to assess tumor volume from hard copies and a survival analysis was conducted in order to evaluate the prognostic significance of preoperative volumetric data in patients harboring glioblastomas.

Patients And Methods: 50 patients suffering from glioblastoma were analyzed retrospectively.

Background: Induction chemotherapy (IC) followed by concomitant chemoradiotherapy (CCRT) has the potential of being an ideal multi-modality approach for improving the prognosis of patients with squamous cell carcinoma of the head and neck (SSCHN).

Patients And Methods: Thirty-four patients with locally advanced SCCHN were treated with 3 cycles of IC, consisting of docetaxel 75 mg/m2 and cisplatin 75 mg/m2 every 3 weeks, followed 3-4 weeks later by definitive radiotherapy (70 Gy) and concomitant weekly cisplatin 40 mg/m2.

Results: After a median follow-up of 27.

Background: Clinical studies have shown that temozolomide (TMZ) and irinotecan demonstrate activity in high grade astrocytic tumors (HGAT). However, the optimal schedule of administration is unknown.

Patients And Methods: In the present study, a total of 45 HGAT patients, 38 with glioblastoma multiforme (GBM) and 7 with anaplastic astrocytoma (AA), were treated with TMZ, 150 mg/m(2) on days 1-5, followed by irinotecan, 150 mg/m(2) on days 6 and 17, every 4 weeks for 6 cycles or until the occurrence of unacceptable toxicity or disease progression.

The primary objective of this phase II study was to access the complete response (CR) rate to a new innovative induction regimen in patients with locally advanced head and neck cancer (LA-HNC). From October 2000 until October 2003 a total of 38 eligible patients (33 men and 5 women) entered the study. The large majority of them presented with a performance status of 0-1 and with clinical stage IV disease.

Background: Clinical research on the treatment of nasopharyngeal cancer (NPC) has been focused primarily on the reduction of incidence of the development of distant metastases as well as the improvement of locoregional control.

Patients And Methods: Untreated patients with stage IIB-IVB nonmetastatic NPC were treated with three cycles of induction chemotherapy (IC) consisting of epirubicin 75 mg/m(2) followed by paclitaxel 175 mg/m(2) as 3-h infusion on day 1 and cisplatin 75 mg/m(2) on day 2 every 3 weeks, followed by concomitant radiation therapy (70 Gy), and chemotherapy (CCRT) with weekly paclitaxel 60 mg/m(2).

Results: From November 1999 until April 2003, 47 patients entered the study.

Purpose: Surgery remains the standard treatment for glioma, followed by radiotherapy (RT) with or without chemotherapy. Despite multidisciplinary approaches, the median survival time for patients with glioblastoma multiform (GBM) remains at less than 1 year from initial diagnosis. Temozolomide (TMZ), an oral alkylating agent, has shown promising activity in the treatment of malignant gliomas.
