Paediatric medulloblastoma cells are susceptible to Viscum album (Mistletoe) preparations.
Medulloblastoma constitute more than 20% of all paediatric brain tumours and are the most common malignant brain tumours in children. Adjuvant chemotherapy has seen a strong increase in the use of complementary medicine for cancer treatment. Evidence for cytotoxic and apoptotic effects of Viscum album (Mistletoe) in vitro is available, however, no data concerning paediatric tumours, especially paediatric brain tumours, has been provided so far. ⋯ These in vitro results show that paediatric medulloblastoma cells respond to Viscum album preparations, by undergoing cell death through apoptosis and that this growth-inhibition correlates with the lectin content of the used preparation.

Post-operative concurrent chemoradiation therapy using oral uracil-tegafur versus weekly intravenous fluorouracil for locally advanced rectal cancer.
This prospective, nonrandomized study was conducted to compare the efficacy and toxicity of post-operative concurrent chemoradiation therapy (CCRT) using daily oral uracil-tegafur plus leucovorin (UFUR/LV) vs. weekly intravenous fluorouracil plus leucovorin (5-FU/LV) in patients with locally advanced rectal cancer. ⋯ Because of a similar survival rate and lower toxicity, oral UFUR/LV is suggested as an alternative regimen to intravenous 5-FU/LV in post-operative CCRT of locally advanced rectal cancer.

Antiproliferative effects of mistletoe (Viscum album L.) extract in urinary bladder carcinoma cell lines.
The aim of the study was to evaluate the antiproliferative potency of Viscum album extract (VA-E) in human bladder carcinoma cell lines with regard to its possible use for intravesical therapy of superficial bladder cancer. ⋯ VA-E and cytotoxic proteins, i.e., mistletoe lectins (ML) and viscotoxins (VT), were able to block the growth of bladder carcinoma cells. Together with the immunomodulating properties of VA-E, the observed antiproliferative potency might give a rationale for the topical intravesical application of VA-E for the treatment of superficial bladder cancer.

Dose-finding study of docetaxel added to ifosfamide and cisplatin followed by concomitant capecitabine and radiotherapy in the treatment of locally advanced squamous cell carcinoma of the head and neck.
Docetaxel (DOC) is a promising new drug in the management of squamous cell carcinoma of the head and neck. The aim of this phase I study was to determine the toxicity and maximum tolerated dose (MTD) as well as to obtain preliminary data on the activity of DOC combined with fixed doses of ifosfamide (IFO) and cisplatin (CDDP), followed by concomitant capecitabine (C) and radiation therapy in the organ-sparing treatment of patients with locally advanced, inoperable squamous cell carcinoma of the head and neck (A-SCCHN). ⋯ Out-patient administration of DOC, IFO and CDDP for A-SCCHN was safe and did not affect the ability to administer chemoradiotherapy on schedule. Myelosuppression was the DLT.

High-grade gliomas: results in patients treated with adjuvant radiotherapy alone and with adjuvant radio-chemotherapy.
Despite advances in the surgical, radiotherapeutic and chemotherapeutic fields, the outcome for patients with high-grade gliomas remains poor. Our experience of patients treated with and without chemotherapy is reported. ⋯ Radio-chemotherapy plus adjuvant temozolomide seemed to offer the best results in patients not submitted to debulking surgery. The performance status remained the most important prognostic factor. Tolerance to the combined regimen was very good.
