- Abstract
Radiotherapy is a key cancer treatment, which greatly modified its practice in recent years thanks to medical imaging and technical improvements. The systematic use of computed tomography (CT) for treatment planning, the imaging fusion/co-registration between CT/magnetic resonance imaging (MRI) or CT/positron emission tomography (PET) improve target identification/selection and delineation. New irradiation techniques such as image-guided radiotherapy (IGRT), stereotactic radiotherapy or hadron therapy offer a more diverse therapeutic armamentarium to patients together with lower toxicity. Radiotherapy, as well as medical oncology, tends to offer a personalized treatment to patients thanks to the IGRT, which takes into account the inter- or intra-fraction anatomic variations. IGRT leads to adaptive radiotherapy (ART) with a new planification in the treatment course in order to decrease toxicity and improve tumor control. The use of systemic therapies with radiations needs to be studied in order to improve efficiency without increasing toxicities from these multimodal approaches. Finally, radiotherapy advances were impacted by radiotherapy accidents like Epinal. They led to an increased quality control with the intensification of identity control, the emergence of in vivo dosimetry or the experience feedback committee in radiotherapy. We will illustrate through the example of lung cancer.

- Abstract
Recurrences or second primary head and neck cancers meant, for a long time, therapeutic dead ends. Surgery was the standard treatment, but could only be achieved in 25% of the patients. The GETTEC-GORTEC (99-01) randomized trial showed that radiochemotherapy improved disease-free survival for a highly selected population. For inoperable patients, three options can be discussed: supportive care only, chemotherapy or radiotherapy with or without chemotherapy. The EXTREME protocol showed that combining platinum, 5FU and cetuximab improved overall survival for recurrent or metastatic forms. This is certainly the best option for advanced forms, which are not accessible to radiotherapy. Concerning radiotherapy, only one randomized trial compared chemoradiotherapy to chemotherapy alone using methotrexate. The overall survival, the main objective in this study, was not improved, however, the enrollment was incomplete and included many advanced stage tumors. Other articles are based on Vokes' initial work of radiochemotherapy delivered in split-course over a period of 11 weeks. All conventional and conformational radiotherapy series showed improved local control and disease-free survival rates, but at the expense of acute and late toxicities demanding a drastic patients selection. New radiotherapy techniques such as intensity modulated radiotherapy (IMRT) and stereotactic body radiotherapy (SBRT) have reduced toxicities with a likely oncological results improvement, offering treatments which are spread over six to seven weeks for IMRT and two weeks for SBRT. The better treatment tolerance allows an increasing number of eligible patients. The main future objective will be to define the specific IMRT and SBRT indications.

- Abstract
Radiation therapy contributes, with others therapeutic means, to cure many cancers without mutilation and sparing conservative functions. In France, in 2010, about 180,000 patients underwent external radiation therapy in 177 centers assumed by 660 radiation oncologists. Many progress and changes have been made during the past years with the implementation of new techniques as conformal and intensity modulated techniques. Renewal of innovative treatment machines is rapidly ongoing. Since 2007, after medical accidents, quality and security policies have been improved and coordinated to a national level with the active cooperation of the main institutional and professional partners. The new national "Plan Cancer 2009-2013" leads to improvement for patients to access to innovative and safe treatments and to clinical research.

- Abstract
Oxygen plays a direct role in cell death after exposure to ionizing radiations and tumour hypoxia, favoured by anaemia, is a factor of poor treatment response. Tumour phenotype is directly influenced by tissue oxygenation, inducing tumour cells adaptation to the environment and potential resistance to treatment. The correction of tumour hypoxia can increase treatment response. It is however difficult to directly correlate pO2 and vascularisation. Vessels from angiogenesis get endothelial cells but have lost the functions of normal vessels (receptors, muscles...). The role of angiogenesis has been demonstrated on initial tumour growth and on metastatic potential and regulation. Many pre clinical studies have demonstrated the benefit of combining anti angiogenic compounds and cytotoxic agents (chemotherapy drugs and ionizing radiations). Clinical studies are on going and new evaluation models of treatment response will be necessary.

- Abstract
Advances in medical imaging have greatly enhanced the speciality of radiation oncology by allowing more healthy tissue to be speared for better tumour coverage. Positron emission tomography (PET) with the glucose analogue [18F]-fluoro-2-deoxy-D-glucose (FDG) is a functional imaging method that has become widely used in oncology over the last decade. It has been rapidly incorporated in the staging and treatment planing of many patients with cancer in several anatomic sites such as non-small cell lung carcinomas. However, the initial data were controversial by the use of non dedicated PET units, the lack of patient immobilisation for radiation therapy, or the lack of image registration for fusion PET images with computed tomography (CT). The increased number of combined PET/CT units installed and the development of new isotopes that allow advances in biological and molecular tumour and healthy tissue imaging should lead to enhanced target definition for highly conformal radiation therapy. Such developments might also allow tumour viability or healthy tissue function to be imaged, which could be used during treatment as early indicators of tumour response or healthy tissue injury, possibly leading to a change in treatment strategy based on functional and biological imaging. The contribution of PET imaging advances using FDG or new tracers for treatment planing in the new era of image guided radiation therapy will be discussed in this review.

- Abstract
Anemia is very common in head and neck cancer patients, and seems to be correlated with intratumoral hypoxia. Anemia is one of the main prognostic factors of locoregional recurrence and, in some studies, of poor survival. Blood transfusions and human recombinant erythropoietin (rHuEPO) are the two main methods used in clinical practice to correct hemoglobin level during curative treatment. Blood transfusions were rarely evaluated, and did not influence locoregional control of patients treated with radiotherapy with or without chemotherapy. Retrospective studies evaluating combined treatment of rHuEPO and radiotherapy reported positive impact on locoregional recurrence and actuarial survival. Since the end of 2003, this approach is a matter for debate after the negative results of a prospective randomized study on progression-free survival concerning head and neck cancer patients treated with definitive or postoperative external radiotherapy with or without rHuEPO. Although many biases were reported against this publication, several questions are to be answered in the near future. Among them, erythropoietin receptor expression and activation on tumour cell seem to be the more appropriate explanation of these negative results. In October 2004, preliminary results of the RTOG 99-03 study have been presented at the Astro annual meeting in Atlanta. This prospective randomized trial was designed to determine if concurrent rHuEPO administration (40,000 units) with radiotherapy (with or without chemotherapy) could improve locoregional control in non-operative head and neck cancers. In the rHuEPO arm, haemoglobin level was significantly increased compared with control arm. However, the addition of concurrent rHuEPO to definitive radiotherapy did not improve locoregional control or survival for mildly/moderately anemic patients with head and neck squamous cell carcinoma. Future clinical trials using biological markers are thus imperative to target which patients could benefit from these molecules.

- Abstract
Little is known about epidemiology of adults soft tissue and visceral sarcomas (ASTS). The frequency of previous cancers and associated genetic diseases has been analyzed out of 493 ASTS, treated between 1997 and 2002 at Oscar Lambret Cancer Center. Median age is 51, sex ratio is close to 1. Liposarcomas and malignant fibrous histiocytofibromas are the two main types (respectively 104 and 86 cases). Upper and lower limbs are the two main locations (respectively 176 and 75 cases). Fifteen patients had associated genetic disease, including 12 cases of Recklinghausen diseases. 7 out of those 15 patients have neurosarcoma. 30 patients have previous cancers, including 7 breast cancers, 3 lymphomas and 3 chronic lymphocytic leukemias. Four out of those 30 patients have two different previous cancers. 13 patients have radiation-induced sarcomas, after an average 10-year-period, and an average dose of 53 Gy. Undifferenciated sarcomas are the main histologic type (8/13), followed by angiosarcomas (2/13). Radiation-induced sarcomas are located in the chest wall (7/13), in pelvis (2/13) and head and neck (2/13). Those sarcomas are high grade (10 grade III tumours). ASTS epidemiology is complex with different risk factors depending on histologic type.

- Abstract
The role of oxygen as an enhancer of the biological effect of ionising radiation is crucial for radiotherapy. Most of the solid tumours have an inadequate vasculature (neo-angiogenesis) leading to hypoxic areas, favoured by anaemia. Many clinical approaches have been used to overcome this problem with oxygen breathing, radiosensitizing drugs or anaemia correction. All these parameters will be developed together with the methods available for measuring tumour oxygenation and the biological consequences of anaemia and hypoxia on tumour physiology.
