European Cancer Organisation Essential Requirements for Quality Cancer Care: Adult glioma.

European Cancer Organisation Essential Requirements for Quality Cancer Care (ERQCCs) are explanations of the organisation and actions necessary to provide high-quality care to patients with a specific cancer type. They are compiled by a working group of European experts representing disciplines involved in cancer care, and provide oncology teams, patients, policymakers and managers with an overview of the essential requirements in any healthcare system. The focus here is on adult glioma. Gliomas make up approximately 80% of all primary malignant brain tumours. They are highly diverse and patients can face a unique cognitive, physical and psychosocial burden, so personalised treatments and support are essential. However, management of gliomas is currently very heterogeneous across Europe and there are only few formally-designated comprehensive cancer centres with brain tumour programmes. To address this, the ERQCC glioma expert group proposes frameworks and recommendations for high quality care, from diagnosis to treatment and survivorship. Wherever possible, glioma patients should be treated from diagnosis onwards in high volume neurosurgical or neuro-oncology centres. Multidisciplinary team working and collaboration is essential if patients' length and quality of life are to be optimised.

Neo-adjuvant chemo-radiation of rectal cancer with volumetric modulated arc therapy: summary of technical and dosimetric features and early clinical experience.

BACKGROUND: To report about initial technical and clinical experience in preoperative radiation treatment of rectal cancer with volumetric modulated arcs with the RapidArc (RA) technology. METHODS: Twenty-five consecutive patients (pts) were treated with RA. All showed locally advanced rectal adenocarcinoma with stage T2-T4, N0-1. Dose prescription was 44 Gy in 22 fractions (or 45 Gy in 25 fractions). Delivery was performed with single arc with a 6 MV photon beam. Twenty patients were treated preoperatively, five did not receive surgery. Twenty-three patients received concomitant chemotherapy with oral capecitabine. A comparison with a cohort of twenty patients with similar characteristics treated with conformal therapy (3DC) is presented as well. RESULTS: From a dosimetric point of view, RA improved conformality of doses (CI95% = 1.1 vs. 1.4 for RA and 3DC), presented similar target coverage with lower maximum doses, significant sparing of femurs and significant reduction of integral and mean dose to healthy tissue. From the clinical point of view, surgical reports resulted in a down-staging in 41% of cases. Acute toxicity was limited to Grade 1-2 diarrhoea in 40% and Grade 3 in 8% of RA pts, 45% and 5% of 3DC pts, compatible with known effects of concomitant chemotherapy. RA treatments were performed with an average of 2.0 vs. 3.4 min of 3DC. CONCLUSION: RA proved to be a safe, qualitatively advantageous treatment modality for rectal cancer, showing some improved results in dosimetric aspects.
