RESUMO
PURPOSE: Treatment according to guidelines has been demonstrated to improve survival in a number of different cancer entities. Deviations from guidelines depend on several factors, including the patient's preferences, age and comorbidities. The aim of this study was to assess the adherence to guideline recommendations concerning surgical and adjuvant treatment in endometrial cancer. Furthermore, we sought to evaluate the reasons for non-adherence to guidelines by further examining the influence of comorbidities and age. METHODS: The influence of age, comorbidities, tumor stage and histological subtype on guideline adherence was evaluated by multivariable logistic regression in a cohort of 353 high-grade endometrial cancer patients. High-grade endometrial cancer was defined as carcinosarcoma, Type II (serous, clear cell, mixed cell carcinoma) and Type I G3 histology. RESULTS: Extensive surgical procedures, particularly systematic LNE, were less frequently applied in patients with comorbidities (p = 0.015) or higher age (p < 0.01). Guideline adherence was not affected by comorbidities (p = 0.563), but was significantly reduced with higher age (p < 0.01). In a multivariable model, higher age (p < 0.01), obesity (p = 0.011), higher FIGO Stage (p < 0.01) and histologic subtype (p < 0.01) significantly decreased OS. Surgery (p < 0.001), chemotherapy (p < 0.01) and systematic LNE (p = 0.011) were associated with higher OS. CONCLUSION: Age seems to be the strongest independent factor leading to guideline deviation. Comorbidities were associated with less aggressive treatment, but not with deviations from guidelines.

BACKGROUND: Similarities in outcome between grade 3 endometrioid cancer and non-endometrioid histologies have been reported by a number of studies. Other reports, however, stated a significantly better prognosis for G3 endometrioid compared to type II histology. In this population-based study, we compared the outcome and treatment approaches of high-grade endometrial cancer patients with FIGO stages I-III depending on their histology. MATERIAL AND METHODS: 284 high-grade endometrial cancer patients diagnosed between 1998 and 2015 were retrospectively analyzed. Overall survival (OS), recurrence-free survival (RFS), and recurrence rates were compared depending on histology. RESULTS: Type I G3 patients had a statistically significant OS advantage over women suffering from type II carcinoma (HR 1.527, 95%-CI 1.024-2.276; p = 0.038) and carcinosarcoma (HR 2.106, 95%-CI 1.270-3.493; p = 0.004) in univariable and multivariable Cox-regression analysis. RFS in Type I G3 was significantly superior compared to patients with carcinosarcoma (HR 1.719, 95%-CI 1.018-2.901; p = 0.043) and not significantly superior to type II patients (HR 1.368, 95%-CI 0.920-2.036; p = 0.122). Cumulative recurrence rates were significantly higher in carcinosarcoma compared to type I G3 (HR 2.217, 95%-CI 1.096-4.485; p = 0.027) in univariable analysis, but not after risk adjustment (HR of 1.472, 95%-CI 0.654-3.311; p = 0.350). CONCLUSION: The prognosis of patients with type I G3 endometrial cancer patients seems to be significantly superior to patients with type II cancer and particularly carcinosarcoma. Systematic LND seemed to be beneficial in all of the three subtypes. The benefit of adjuvant treatment methods may differ between histologies.

PURPOSE: Due to insufficient and conflicting prospective evidence, the recommendations on when to apply adjuvant radiochemotherapy in early-stage cervical cancer vary between international guidelines. In this population-based study, we evaluated the outcome of patients with early-stage cervical cancer based on risk factors and the adjuvant therapy they received. METHODS: The effect of primary therapy (surgery and radiochemotherapy RCT, surgery and radiotherapy RT, and surgery alone) on overall survival (OS) and recurrence-free survival (RFS) was evaluated in the complete cohort of 442 patients and in subgroups according to risk profile and nodal status. RESULTS: In low-risk patients, there was no difference in OS (p = 0.276) depending on whether patients received adjuvant therapy or not. Concerning RFS, patients with RT (including one patient with RCT) exhibited a significantly worse outcome compared to the group with surgery alone (p = 0.015). In intermediate-risk patients, the administration of adjuvant RT significantly benefited RFS when compared to surgery only in multivariate analysis (p = 0.031). Concerning OS, no significant influence for adjuvant treatment could be seen (p = 0.354). Though trends towards better OS and RFS could be observed in patients of the high-risk group-both in RCT and RT groups compared to surgery alone-the effects did not prove to be significant. CONCLUSION: Our study reaffirms the evidence against the use of adjuvant radio(chemo)therapy in low-risk early-stage cervical cancer. In intermediate-, and less pronounced in high-risk patients, however, it seems to be beneficial. The role of adjuvant radio(chemo)therapy in early cervical cancer should be further investigated in prospective randomized trials.

PURPOSE: Osteoarthritis of the ankle and tarsal joints is less common than osteoarthritis of the knee or hip, but the associated disability is at least as severe as that of the other major joints of the lower limb. The results for total arthroplasty are still not satisfactory. For this reason, arthrodesis is still the gold standard of non-joint-conserving surgery. For the reason of functionality, joint-conserving therapies play a major role in treatment of ankle and tarsal osteoarthritis. Low-dose radiotherapy has a long history of treatment of osteoarthritis. The aim of this survey was to examine the results of low-dose radiotherapy for osteoarthritis of the ankle and tarsal joints. MATERIALS AND METHODS: The analysis was performed on patients of three German radiotherapy institutions and included 66 irradiated joints. Pain was documented with the numeric rating scale (NRS). Evaluation of the NRS was done before and directly after each radiation therapy course as well as for the follow-up of 24 months. The median age of the patients was 68 years, with 24.5% male and 75.5% female patients. The upper ankle was treated in 37.9%, the lower ankle in 27.3% and the tarsal joints in 34.8%. RESULTS: We could find a significant response to radiotherapy. For the whole sample, the median pain was 7 on the NRS before radiotherapy, 5 after 6 and 12 weeks, and 4 after 12 months. The percentage of patients with 0 or 1 on the NRS was 19.6% 12 months after radiotherapy. An improvement of joint mobility could be detected in 56.7% of the cases. All investigated subgroups had a significant reduction in pain. CONCLUSION: Radiotherapy of ankle and tarsal osteoarthritis is an effective treatment without showing side effects. All analysed subgroups show a good response to radiotherapy for at least 24 months.

BACKGROUND: Humeral epicondylitis is a common elbow disease. The prevalence is about 1.7%. One of the most effective treatment options is radiotherapy. Some authors mention that they apply a second or third course of radiation for recurrent pain or partial or no response to the initial course. As the results of a re-irradiation have not been systematically analyzed, the aim of this study was to document the results of repeated radiation treatment and to identify those patients who will benefit. MATERIAL AND METHODS: The analysis was performed on patients from three German radiotherapy institutions and included 99 re-irradiated elbows. Pain was documented with the numeric rating scale (NRS). Evaluation of the NRS was done before and directly after each radiation therapy as well as for the follow-up of 24 months. The median age of the patients was 51 years with 48.8% male and 51.2% female patients. Repeated radiation was indicated because the initial radiotherapy resulted in 39.7% of no response, in 41.0% of partial response and in 19.3% of recurrent pain. RESULTS: A significant response to re-irradiation was found. For the whole sample the median pain score was 6 before re-irradiation, 3 after 6 weeks, 2 after 12 months and 1 after 24 months. The percentage of patients being free of pain or with very little pain was 50.9% 24 months after re-irradiation. All subgroups, notably those with no response, partial response and recurrent pain had a significant reduction of pain. CONCLUSION: Re-irradiation of humeral epicondylitis is an effective and safe treatment. All subgroups showed a good response to re-irradiation for at least 24 months.

PURPOSE: Osteoarthritis is a common disease, with a prevalence of symptomatic disease of 8.9%. One treatment option is radiotherapy. Most published samples were treated with an orthovoltage technique or with a telecobalt device. A lot of radiotherapy institutions are nowadays using linear accelerators for treatment of osteoarthritis. There is a discussion on whether the treatment results achieved with a linear accelerator are comparable to those with the orthovoltage technique. The aim of this study is to analyze the results of radiotherapy for osteoarthritis with a linear accelerator and compare the results with reference to different joints. MATERIALS AND METHODS: The analysis was performed in patients of two German radiotherapy institutions and included 295 irradiated joints. Pain was documented with the numeric rating scale (NRS). Evaluation of the NRS was done before and directly after each radiation therapy course as well as for the follow-up of 24 months. The median age of the patients was 65 years, with 39.0% male and 61.0% female patients. Most frequently, osteoarthritis of the knee (34.6%) or the finger (15.9%) was treated. RESULTS: We could find a significant response to radiotherapy. Median pain for the whole sample was 7 on the NRS before radiotherapy, 4 after 6 weeks, and 3 after 12 and 24 months. The percentage of patients with 0 or 1 on the NRS was 33.8% 12 months after radiotherapy. All investigated subgroups had a significant reduction of pain. CONCLUSION: Radiotherapy of osteoarthritis with a linear accelerator is an effective treatment which is very well tolerated. All analyzed subgroups show a good response to radiotherapy for at least 24 months. Orthovoltage therapy seems to be superior to treatment with a linear accelerator in a case-related analysis of the published samples. Further investigations should be performed for a definitive answer to this question.

Actinic keratoses (AK) are common lesions in light-skinned individuals that can potentially progress to cutaneous squamous cell carcinoma (cSCC). Both conditions may be associated with significant morbidity and constitute a major disease burden, especially among the elderly. To establish an evidence-based framework for clinical decision making, the guideline "actinic keratosis and cutaneous squamous cell carcinoma" was developed using the highest level of methodology (S3) according to regulations issued by the Association of Scientific Medical Societies in Germany (AWMF). The guideline is aimed at dermatologists, general practitioners, ENT specialists, surgeons, oncologists, radiologists and radiation oncologists in hospitals and office-based settings as well as other medical specialties involved in the diagnosis and treatment of patients with AK and cSCC. The guideline is also aimed at affected patients, their relatives, policy makers and insurance funds. In the first part, we will address aspects relating to diagnosis, interventions for AK, care structures and quality-of-care indicators.

PURPOSE: Ionizing radiation is able to cause severe damage to cardiac implantable electronic devices (CIED). In Germany, the DEGRO/DGK guideline recommends close monitoring of patients with CIEDs undergoing radiotherapy (RT). Nevertheless, especially in the era of intensity-modulated techniques and predominant use of 6â¯MV photons, errors of CIEDs are rare events. Therefore, we performed daily CIED controls and hypothesized that no relevant device interaction would occur in our cohort. METHODS: From 2014 to 2018, we collected data of 51 patients (62 courses) with daily interrogation (nâ¯= 1046) of CIED. The dose to the skin above the CIED was measured by semiconductor or ion chamber dosimetry at least once per RT course. In many cases the dose was also calculated. RESULTS: The prescribed dose to the planning target volume (PTV) ranged from 7.5 to 78.0â¯Gy (IQR 27.8-61.0â¯Gy). The median measured cumulative dose to the skin above the CIED was 0.17â¯Gy, whereas the median calculated dose was 1.03â¯Gy. No error occurred in the group with maximum beam energy >10â¯MeV. Three events without clinical relevance could be recognized in the group with an intensity-modulated technique at 6â¯MV. None of the three concerned devices were located directly within the PTV. CONCLUSION: Errors of CIEDs during RT are rare events. The approach according to the DEGRO/DGK guideline is safe, but also consumes resources. In our cohort it was not compulsory to relocate any CIED. Clinically relevant events are uncommon, so it remains debatable which procedure is necessary. Daily controls could be avoided in some selected cases without compromising patient safety.

PURPOSE: Osteoarthritis is a common disease with a prevalence of approximately 8.9% among the average population. One treatment option is low-dose radiotherapy. Some authors mention that they apply a second or third course of radiation for recurrent pain or partial or no response to the initial course. As the results of re-irradiation have not been analysed systematically, the aim of this study was to document the results of repeated radiation treatment and to identify those patients who will benefit. METHODS AND MATERIALS: The analysis was performed on patients of three German radiotherapy institutions and included 217 re-irradiated joints. Pain was documented with the numeric rating scale (NRS). Evaluation of the NRS was done before and directly after each radiation therapy as well as at the follow-up of 24 months. The median age of the patients was 67 years, with 40% male and 60% female patients. Re-irradiation was indicated because the initial radiotherapy resulted in no response in 21.2%, in partial response in 41.5%, and in recurrent pain in 37.3%. RESULTS: We found a significant response to re-irradiation. For the whole sample, the median pain was 6 before re-irradiation, 4 after 6 weeks, and 3 after 12 weeks, 6 months, 12 months, and 24 months. The percentage of patients being free of pain or with very little pain was approximately 25% 12 months after re-irradiation. All subgroups, notably those with no response to the first course versus partial response to the first course versus recurrent pain, had significant reduction of pain. CONCLUSION: Re-irradiation of osteoarthritis is an effective and safe treatment. All subgroups showed a good response to re-irradiation for at least 24 months.

BACKGROUND: Epicondylitis humeri is a common disease with a prevalence of 1.7%. One of the treatment options is radiotherapy. Most published cases were treated with the orthovoltage technique or with a telecobalt device. Many radiotherapy institutions are nowadays using linear accelerators for treatment of epicondylitis humeri. There is a discussion whether the treatment results with linear accelerators are comparable to the orthovoltage technique. The aim of this study was to analyze the results of radiotherapy with a linear accelerator for epicondylitis humeri. MATERIAL AND METHODS: The analysis was performed on patients of 2 German radiotherapy institutions and included 138 irradiated elbows. Pain was documented with the numeric rating scale (NRS). Evaluation of the NRS was done before and directly after each radiation therapy course as well as for the follow-up of 24 months. The median age of the patients was 49 years with 48.4% male and 51.6% female. In all, 81.0% were suffering from from epicondylitis humeri radialis while 16.7% were treated because of epicondylitis humeri ulnaris. In 65.4% the dominant arm was treated. RESULTS: A significant response to radiotherapy could be found. For the whole sample the median pain was 7 on the NRS before radiotherapy, 4 after 6 weeks and 0 after 12 and 24 months. The percentage of patients with 0 or 1 on the NRS was 64.6% 12 months after radiotherapy. All subgroups, notably those with epicondylitis humeri radialis and epicondylitis humeri ulnaris had a significant reduction of pain. CONCLUSION: Radiotherapy of epicondylitis humeri with a linear accelerator is an effective treatment without showing side effects. All analyzed subgroups showed a good response to radiotherapy for at least 24 months.

PURPOSE: Osteoarthritis of the knee is a common disease, often associated with a Baker's cyst. Besides osteoarthritis, also other joint pathologies of the knee can be causative for a Baker's cyst. Radiotherapy is known to be an effective treatment for osteoarthritis, with an anti-inflammatory effect. As the excessive production of synovia usually is associated with intraarticular inflammation, our hypothesis was that radiotherapy might positively influence the synovial production and reduce the volume of a Baker's cyst. MATERIALS AND METHODS: We performed a prospective trial, including 20 knees receiving radiotherapy for knee arthritis. Besides documentation of NRS (numeric rating scale), WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) score and Knee Society Score, the volume of the Baker's cyst was calculated for a short- (6 to 12 weeks) and long-term (9 to 12 months) follow-up. Ultrasonic volumetry was performed using an ultrasound device with a high-resolution multifrequency linear probe (6-9â¯MHz). RESULTS: Low-dose radiotherapy improved NRS, WOMAC score and Knee Society Score significantly. The mean volume of Baker's cyst decreased from 22.3â¯ml to 10.7 respectively 3.1â¯ml during follow-up. A decrease in volume of more than 25% compared to the baseline could be achieved for 75% of the patients in the short-term and 79% of the patients in the long-term follow up. CONCLUSION: Radiotherapy of knee osteoarthritis is an effective treatment that decreases the volume of a Baker's cyst. Most patients respond to the treatment. Whether radiotherapy is an effective treatment for Baker's cyst without associated osteoarthritis has to be further examined.

PURPOSE: Vaginal brachytherapy reduces the risk of local recurrence and was shown to be equieffective in preventing vaginal vault recurrence, but less toxic compared to external-beam radiotherapy in a subset of high intermediate-risk endometrial cancer patients and is administered as single adjuvant treatment in those patients. Different radiotherapeutic approaches with various dosing schemes exist toward brachytherapy. The aim of this study was to compare the outcome and long-term quality of life after brachytherapy with two different high-dose-rate dosing schemes. METHODS: Retrospective analysis was conducted of the recurrence and survival rates of 104 patients with endometrial cancer FIGO stage I-II that underwent adjuvant brachytherapy with three times 5 Gy or four times 5 Gy to the upper two-thirds of the vaginal vault in two different institutions between January 2010 and December 2013. Quality of life was assessed by EORTC QLQ-30 questionnaire and EN 24 module. RESULTS: The vaginal vault recurrence rates were 4.9% and 5.0% for patients treated with 3 × 5 Gy and 4 × 5 Gy, respectively (p = 0.98). We did not observe a difference in pelvic recurrence (p = 0.96), overall survival (p = 0.33) or quality of life between the different radiotherapy regimens. Metastatic recurrence and the use of chemotherapy contribute to impairment on quality of life. Younger patients (< 70 years) reported worse emotional functioning (p = 0.02) and higher symptom scales of diarrhea (p = 0.01) and financial problems (p = 0.03). Sexual activity was lower in patients younger than 70 years (p = 0.05). CONCLUSIONS: Further prospective studies are needed to evaluate the effect of dosing schemes on recurrence rates and quality of life. Younger patients (< 70 years) seem to experience greater reduction in quality of life due to endometrial cancer diagnosis.

Patients with brain tumours face a number of medical and social challenges. Previous studies have shown that these patients and their relatives need a high level of patient-oriented information and counselling. However, these needs are often underestimated. In this single-centre cross-sectional study, we evaluated, for the first time, the information needs of patients with brain tumours and their relatives depending on diagnosis, age and level of education. The participants were interviewed using pre-specified questionnaires. Answers were evaluated descriptively using standard statistical methods. A total of 888 questionnaires were sent out. The return rate was 50.7%. The majority of patients (nP = 103; 59.9%) and a higher proportion of relatives (nR = 103; 72.5%; p = 0.019) wished to receive a maximum of information. The majority (79.7% of patients; 83.1% of relatives) also stated that they preferred a personal, face-to-face meeting as primary source of information. The need for information increased with education (p = 0.015), and decreased with tumour grade (p = 0.025) and age (p = 0.118). Our data indicate that patients with brain tumours and their relatives have high information needs throughout their disease and continuously require information and counselling. Optimal provision of information is based on personal preferences, which needs to be evaluated appropriately. Patient-oriented information and counselling are parts of a successful communication strategy that can improve cancer care significantly.

PURPOSE: Adjuvant treatment of high-grade endometrial cancer varies greatly due to the lack of definitive results from controlled randomized trials on the subject. In a retrospective study, we sought to investigate the influence of post-operative radio-, chemo, and radiochemotherapy on survival time and recurrence rates among high-grade endometrial cancer patients. METHODS: 284 high-grade endometrial cancer patients (FIGOI-III, or unknown classification) diagnosed between 1998 and 2015 were retrospectively analyzed. All patients underwent surgery. Overall survival (OS), recurrence-free survival (RFS), and recurrence rates were compared for post-operative treatment modalities of radiotherapy alone (RT), chemotherapy alone (CTX), radiochemotherapy (RCT), and observation (OBS). RESULTS: Post-operative RCT and RT resulted in a significantly improved 5-year OS of 94.1% (HR 0.104, CI 0.013-0.809) and 62.1% (HR 0.615, CI 0.390-0.969), respectively, compared to 43.6% for OBS. CTX did not significantly improve OS leading to a 5-year OS of 56.5% (HR 0.783, CI 0.224-2.740). 5-year recurrence rate was lowest for patients treated with RCT (5.3%). 5-year RFS was 94.1% for the RCT group and proved to be significantly superior to 58.8% for RT (HR 9.034, CI 1.184-68.948), 56% for CTX (HR 12.738, CI 1.337-121.346), and 37.4% for OBS (HR 16.407, CI 2.127-126.575), respectively. In comparison with OBS, RT alone resulted in a significant improvement in RFS (HR 0.551, CI 0.354-0.856). CONCLUSIONS: Our retrospective population-based study indicates a survival benefit from treating high-grade endometrial cancer with post-operative RCT. Randomized controlled trials are needed to minimize potential confounding parameters and further clarify the subject.

Tumor-induced osteomalacia (TIO) is a paraneoplastic syndrome resulting in renal phosphate wasting and decreased bone mineralization. TIO is usually induced by small, slowly growing tumors of mesenchymal origin (phosphaturic mesenchymal tumor mixed connective tissue variant [PMTMCT]). Nonspecific symptoms including fatigue, bone pain, and musculoskeletal weakness make the diagnosis elusive and often lead to a delay in treatment. The prognosis of TIO is excellent following complete resection of the neoplasm, which leads to the rapid and complete reversal of all symptoms. If the tumor cannot be detected, treatment relies on supplementation with phosphate and active vitamin D compounds. Subsequent radiotherapy in case of incompletely resected tumors or definitive radiotherapy in unresectable tumors is an important treatment option to avoid recurrence or metastasis even though this occurs rarely. Due to the risk of recurrence or late metastases, long-term monitoring is required even in TIO patients diagnosed with a benign tumor.

BACKGROUND: Many cancer patients receive a central venous catheter or port system prior to therapy to assure correct drug administration. Even appropriate hygienic intervention maintenance carries the risk of contaminating the middle port (C-port) of a three-way cock (TWC), a risk that increases with the number of medical interventions. Because of the complexity of the cleaning procedure with disconnection and reconnection of the standard luer lock cap (referred as "intervention"), we compared luer lock caps with a "closed access system" consisting of a luer access split septum system with regard to process optimization (work simplification, process time), efficiency (costs) and hygiene (patient safety). METHODS: For determination of process optimization the workflow of an intervention according to the usual practice and risks was depicted in a process diagram. For determining the actual process costs, we analyzed use of material and time parameters per intervention and used the process parameters for programming the process into a simulation run (n = 1000) to determine the process costs as well as their differences (ACTUAL vs. NOMINAL) within the framework of a discrete event simulation.Additionally cultures were carried out at the TWC C-ports to evaluate possible contamination. RESULTS: With the closed access system, the mean working time of 5.5 minutes could be reduced to 2.97 minutes. The results for average process costs (labour and material costs per use) were 3.92 for luer lock caps and 2.55 for the closed access system. The hypothesis test (2-sample t-test, CI 0.95, p-value<0.05) confirmed the significance of the result.In 50 reviewed samples (TWC's), the contamination rate for the luer lock cap was 8% (4 out of 50 samples were positive), the contamination rate of the 50 samples with the closed access system was 0%.Possible hygienic risks (related to material, surroundings, staff handling) could be reduced by 65.38%. CONCLUSIONS: In the present research, the closed access system with a divided split septum was superior to conventional luer lock caps. The advantage of the closed access system lies in the simplified handling for staff, which results in a reduced risk of patient infection due to improved clinical hygiene.
