Abstract Purpose We conducted a patterns-of-care survey on chemoradiation for locoregionally confined anal cancer in Austria to evaluate areas of disagreement and to identify possible targets for further standardization. Methods An anonymous questionnaire comprising 38 questions was sent to all Austrian radiation oncology departments. Results were analyzed descriptively and compared to two international guidelines. Results The response rate was 93%. Work-up generally includes DRE, endoscopy, and cross-sectional imaging of chest/abdomen and pelvis. PET-CT is used by 38%. Screening for HIV and biopsies of suspicious lymph nodes are infrequently used. All centers perform IMRT, mainly with daily IGRT. Median doses to the primary are 54.7 Gy (T1–2) and 59.4 Gy (T3–4). Suspicious nodes receive a boost (median dose 54 Gy), while elective nodal areas are mainly treated with 45–50.4 Gy. Target delineation of elective nodal areas seems generally uniform, although disagreement exists regarding inclusion of the common iliac nodes. No agreement was found for OAR-delineation and dose constraints. Concurrent chemotherapy is mitomycin and 5‑FU/capecitabine. Supportive care beyond skin care is infrequently offered. Intensive follow-up is performed for at least 5 years. Treatment of T1N0 shows considerable disagreement. Conclusion We found a high rate of agreement between the centers and concordance with major guidelines. PET-CT, routine HIV testing, and biopsies of suspicious LN seem underrepresented. The largest controversy regarding target volumes concerns inclusion of the common iliac nodes. Prescribed doses are generally in line with the recommendations or higher. OAR delineation, dose constraints, supportive care, and treatment of early anal cancer represent areas for further standardization.

105 Background: Radiation oncologists are frequently involved in providing palliative and supportive care (PSC) for patients with advanced cancers through delivery of palliative radiation. Whether they are confident in their ability to assess and initiate treatments for pain, non-pain, and psychosocial distress is unknown. The American Society for Radiation Oncology (ASTRO) surveyed its practicing members in the United States on self-assessment of their primary PSC skills, and access to continuing medical education on PSC. Methods: We electronically surveyed 4,093 practicing radiation oncologists in the United States. The survey consisted of 17-questions in five sections: demographics, PSC training, domains of PSC, perceived barriers as a radiation oncologist to initiate advanced care planning, and discussion on prognosis. Results: The majority (91%) of radiation oncologists surveyed believe PSC is an important competency for radiation oncologists. Most radiation oncologists reported that they are moderately confident in their ability to assess and manage pain and GI symptoms but less confident in their ability to manage anorexia, anxiety, and depression. Despite areas of decreased confidence, a large number (42%) of radiation oncologists do not receive any additional PSC education beyond their residency training. Lastly, a perceived fear of upsetting referring medical oncologists and lack of clinic time are concerns for radiation oncologists who may want to initiate goals of care/advance care planning discussions with patients and their families. Conclusions: Radiation oncologists are more confident in their ability to assess and manage pain than in their ability to manage depression, anxiety, anorexia, and fatigue. There is a need for increasing continuing medical educational efforts in PSC for practicing radiation oncologists, and strengthening PSC training in residency programs.

Cholangiokarzinome oder cholangiozelluläre Karzinome (CCC) sind seltene Tumoren des biliären Systems mit einer Inzidenz von 2–4/100000 pro Jahr. Zu ihnen zählen die perihilären Gallengangskarzinome (Klatskin-Tumore), mit ca. 60% das häufigste CCC, die peripheren (intrahepatischen) Cholangiokarzinome, das Gallenblasenkarzinom, die Karzinome der extrahepatischen Gallengänge und das periampulläre Karzinom. Zum Zeitpunkt der Diagnose ist nur bei etwa 20% eine chirurgische Resektion als einzige kurative Therapieoption möglich. Die Lebertransplantation ist wegen der hohen Rezidivrate derzeit nicht indiziert. Die Prognose von nicht resektablen Cholangiokarzinomen ist mit einer mittleren Überlebenszeit von sechs bis acht Monaten schlecht. Eine wirksame Therapie zur Verlängerung der Überlebenszeit existiert aktuell nicht. Die wichtigste Massnahme im Rahmen der «best supportive care» ist die Beseitigung der Cholestase (endoskopisch, perkutan oder chirurgisch), um einer Cholangitis oder Cholangiosepsis vorzubeugen. Durch eine systemische Chemotherapie lassen sich Ansprechraten von ca. 20% erreichen. 5-FU und Gemcitabine sind die derzeit am häufigsten eingesetzten Substanzen, die mit einer perkutanen oder endoluminalen Bestrahlung kombiniert werden können. Multimodale Therapiekonzepte können im Einzellfall erfolgreich sein, müssen jedoch erst in Evidence-Based-Medicine-gerechten Studien evaluiert werden, bevor Therapieempfehlungen für die Praxis formuliert werden können.

SummaryRadiobiological and cell biological knowledge is increasingly used to further improve local tumour control or to reduce normal tissue damage after radiotherapy. Important research areas are evolving which need to be addressed jointly by nuclear medicine and radiation oncology. For this differences of the biological distribution of diagnostic and therapeutic nuclides compared with the more homogenous dose-distribution of external beam radiotherapy have to be taken into consideration. Examples for interdisciplinary biology-based cancer research in radiation oncology and nuclear medicine include bioimaging of radiobiological parameters characterizing radioresistance, bioimage-guided adaptive radiotherapy, and the combination of radiotherapy with molecular targeted drugs.

Summary:PET/CT imaging is most likely to be of use in radiation oncology with patients who have poorly defined target volume areas, e.g. brain tumours, bronchogenic carcinoma, and cases of miscellaneous geographical miss. Other tumours that call for dose escalated radiotherapy, such as head and neck tumours, bronchogenic carcinoma, and prostate carcinomas may further benefit from an accurate delineation of the metabolically active tumour volume and its differentiation from surrounding healthy tissue, or tumour atelectasis.
