- Abstract
Objective: With the increasing complexity of oncological therapy, the number of inpatient admissions to radiotherapy and non-radiotherapy departments might have changed. In this study, we aim to quantify the number of inpatient cases and the number of radiotherapy fractions delivered under inpatient conditions in radiotherapy and non-radiotherapy departments., Methods: The analysis is founded on data of all hospitalized cases in Germany based on Diagnosis-Related Group Statistics (G-DRG Statistics, delivered by the Research Data Centers of the Federal Statistical Office). The dataset includes information on the main diagnosis of cases (rather than patients) and the performed procedures during hospitalization based on claims of reimbursement. We used linear regression models to analyze temporal trends. The considered data encompass the period from 2008 to 2017., Results: Overall, the number of patients treated with radiotherapy as inpatients remained constant between 2008 (N = 90,952) and 2017 (N = 88,998). Starting in January 2008, 48.9% of 4000 monthly cases received their treatment solely in a radiation oncology department. This figure decreased to 43.7% of 2971 monthly cases in October 2017. We found a stepwise decrease between December 2011 and January 2012 amounting to 4.3%. Fractions received in radiotherapy departments decreased slightly by 29.3 (95% CI: 14.0-44.5) fractions per month. The number of days hospitalized in radiotherapy departments decreased by 83.4 (95% CI: 59.7, 107.0) days per month, starting from a total of 64,842 days in January 2008 to 41,254 days in 2017. Days per case decreased from 16.2 in January 2008 to 13.9 days in October 2017., Conclusion: Our data give evidence to the notion that radiotherapy remains a discipline with an important inpatient component. Respecting reimbursement measures and despite older patients with more comorbidities, radiotherapy institutions could sustain a constant number of cases with limited temporal shifts., (© 2021.

- Abstract
Purpose: The current status of German residency training in the field of radiation oncology is provided and compared to programmes in other countries. In particular, we present the DEGRO-Academy within the international context., Methods: Certified courses from 2018 and 2019 were systematically assigned to the DEGRO-Curriculum, retrospectively for 2018 and prospectively for 2019. In addition, questionnaires of course evaluations were provided, answered by course participants and collected centrally., Results: Our data reveal a clear increase in curriculum coverage by certified courses from 57.6% in 2018 to 77.5% in 2019. The analyses enable potential improvements in German curriculum-based education. Specific topics of the DEGRO-Curriculum are still underrepresented, while others decreased in representation between 2018 and 2019. It was found that several topics in the DEGRO-Curriculum require more attention because of a low DEGRO-curriculum coverage. Evaluation results of certified courses improved significantly with a median grade of 1.62 in 2018 to 1.47 in 2019 (p = 0.0319)., Conclusion: The increase of curriculum coverage and the simultaneous improvement of course evaluations are promising with respect to educational standards in Germany. Additionally, the early integration of radiation oncology into medical education is a prerequisite for resident training because of rising demands on quality control and increasing patient numbers. This intensified focus is a requirement for continued high standards and quality of curriculum-based education in radiation oncology both in Germany and other countries.

- Abstract
Purpose: Total neoadjuvant therapy is a new paradigm for rectal cancer treatment. Optimal scheduling of preoperative chemoradiotherapy (CRT) and chemotherapy remains to be established., Patients and Methods: We conducted a multicenter, randomized, phase II trial using a pick-the-winner design on the basis of the hypothesis of an increased pathologic complete response (pCR) of 25% after total neoadjuvant therapy compared with standard 15% after preoperative CRT. Patients with stage II or III rectal cancer were assigned to group A for induction chemotherapy using three cycles of fluorouracil, leucovorin, and oxaliplatin before fluorouracil/oxaliplatin CRT (50.4 Gy) or to group B for consolidation chemotherapy after CRT. Secondary end points included toxicity, compliance, and surgical morbidity., Results: Of the 311 patients enrolled, 306 patients were evaluable (156 in group A and 150 in group B). CRT-related grade 3 or 4 toxicity was lower (37% v 27%) and compliance with CRT higher in group B (91%, 78%, and 76% v 97%, 87%, and 93% received full-dose radiotherapy, concomitant fluorouracil, and concomitant oxaliplatin in groups A and B, respectively); 92% versus 85% completed all induction/consolidation chemotherapy cycles, respectively. The longer interval between completion of CRT and surgery in group B (median 90 v 45 days in group A) did not increase surgical morbidity. A pCR in the intention-to-treat population was achieved in 17% in group A and in 25% in group B. Thus, only group B ( P < .001), but not group A ( P = .210), fulfilled the predefined statistical hypothesis., Conclusion: Up-front CRT followed by chemotherapy resulted in better compliance with CRT but worse compliance with chemotherapy compared with group A. Long-term follow-up will assess whether improved pCR in group B translates to better oncologic outcome.

- Abstract
Purpose: Considering the various comorbidities associated with aging, the feasibility and usefulness of concurrent chemoradiotherapy (CRT) in older patients with inoperable non-small cell lung cancer (NSCLC) is a controversial issue. Here, we compared the feasibility of CRT and the effects of various comorbidities on the prognosis of a minimally selected population of inoperable NSCLC patients aged 60-77 years., Patients and Methods: The study comprised 161 patients with inoperable NSCLC who received CRT with a target radiation dose greater than 60 Gy and platinum-based chemotherapy from 1998 to 2007. The total population included 69 patients aged 60-69 years and 53 aged 70-77 years. These two age cohorts were included in the study with a follow-up of a median 14.5 months., Results: The two groups showed no differences in long-term survival, as reflected by the 5-year survival rates of 13.0 ± 4.1 % (60- to 69-year-olds) and 14.4 ± 4.9 % (70- to 77-year-olds). During the treatment phase, the groups were comparable in terms of toxicity and the feasibility of chemotherapy. Compared to patients in their 60s, the septuagenarians had more pulmonary comorbidities (p = 0.02), diabetes mellitus (p = 0.04), cardiac comorbidities (p = 0.08), and previous cancer disease (p = 0.08) that exerted a negative effect on survival. In patients without comorbidities, there were no differences between the age groups., Conclusion: Age is not a contraindication for concurrent CRT per se, because elderly patients do not have a worse long-term prognosis than younger seniors. However, "elderly patients" (≥ 70-77 years) have more concomitant diseases associated with shorter survival than "moderately aged patients" (≥ 60-69 years).

- Abstract
Background and Purpose: Gastric carcinoma is characterized by a high rate of local recurrences and distant metastases and is often not resectable due to locally advanced stage. The aim of this study was to examine feasibility and effectiveness of neoadjuvant radiochemotherapy (RCT) for locally advanced, primarily nonresectable gastric carcinoma and to achieve curative resection., Patients and Methods: 21 patients with locally advanced gastric cancer located in cardia (n = 17) and corpus (n = 4; seven cT3; 14 cT4; 18 cN+; all cM0) with a median age of 61 years were scheduled to receive neoadjuvant RCT. Therapy consisted of a conventionally fractionated, conformal radiotherapy using the shrinking-field technique (1.8 Gy to 45 Gy + 5.4 Gy) and chemotherapy using cisplatin (20 mg/m(2), d1-5, 29-33), 5-fluorouracil (5-FU; 800 mg/m(2), d1-5, 29-33) or paclitaxel (135 mg/m(2), d1, 29). 4-6 weeks after completion of RCT, surgery was performed whenever feasible., Results: Hematologic toxicity was moderate with grade 3 leukopenia in 10/21 patients and grade 3 thrombopenia in 5/21 (CTC). Nonhematologic toxicities consisted of 5/21 cases of fever as well as one fungal sepsis. Following RCT, tumors were classified resectable in 16/21 patients (76%); 12/21 patients (58%) were operated on, 11/12 achieved clear margins (R0). Response was as follows: complete remission (CR) 3/21 (14%), partial remission 13/21 (62%), no change 3/21 (14%), systemic progressive disease (PD) 2/21 (10%). The median survival and the 2-year survival rates were 18 months and 42%, respectively, for the patients following R0 resections as compared to 10 months and 0% for the remaining patients (p = 0.035). Local control (4 years) for patients following R0 resection was 89%., Conclusion: Neoadjuvant RCT is feasible and locally highly effective but must be further investigated involving a higher number of patients.
