- Abstract
Introduction: Cancer diagnoses are constantly increasing in clinical practice. Therefore, more and more patients are interested in how they can actively participate in the process of treatment. Spirituality represents a hidden issue of the population, which counts as a branch of complementary and alternative treatment. Therefore, the aim of our study was to investigate whether there are associations between spirituality and demographic and psychosocial factors, as well as religious beliefs, in cancer patients., Methods: We conducted a survey with 451 participants in 10 oncology centers between March and July 2021. A composition of the following 9 different questionnaires was used to collect data on spirituality, demographics, resilience, self-efficiency, life satisfaction, and sense of coherence: Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp12), General Life Satisfaction Short Scale (L-1), Resilienzskala Kurzform (RS-13), Sense of Coherence Scale - Leipziger Kurzform (SOC-L9), Allgemeine Selbstwirksamkeit Kurzskala (AKSU), Adolescent Food Habits Checklist, Likert-Scale of daily activities, questionnaire of the Working group Prävention und Integrative Onkologie (PRiO), and personal opinion on the cause of the disease. Calculated data and analyzed group differences using ANOVA Bonferroni were used to test associations between spirituality and the variables studied. For more detailed examination of spirituality, we took a closer look at the different components of spirituality - peace, meaning, and faith - and their relation to each other (three-factor spirituality analyses)., Results: Higher spirituality scores in total as well as meaning, peace, and faith were each associated with higher levels of resilience and life satisfaction. Higher religious belief was found to be associated with higher spiritual attitudes. High personal self-efficiency was found in people with higher spiritual beliefs in general as well as higher meaning and peace. Meaning and peace emerge as essential components of spiritual well-being and show a stronger association with expressions of general spirituality than faith., Conclusion: Spirituality takes a crucial role among the resources of life-threatening diseases. As such, further research is needed to expand and integrate patient options into a modernized concept of care. Our data indicate that higher spiritual well-being is associated with a more tolerant approach to illness. Thus, addressing spiritual needs in therapy is associated with better psychological adjustment to the individual situation and reduces negative distress. To promote spiritual needs in the future, cognitive as well as affective components of spirituality should be emphasized., (© 2024 S. Karger AG, Basel.)

- Abstract
Purpose: For patients with a cancer diagnosis, coping abilities are of high importance. Cancer patients with a high sense of coherence may cope better. The purpose of this study is to learn more about the correlation of sense of coherence and different aspects, such as demographics, psychological factors, lifestyle, complementary and alternative medicine (CAM) and lay aetiology., Methods: A prospective cross-sectional study was performed in ten cancer centres in Germany. The questionnaire consisted of ten sub-items, collecting information about sense of coherence, demographics, general life satisfaction, resilience, spirituality, self-efficacy, physical activity and sports, nutrition, CAM methods and cancer causes., Results: As many as 349 participants were evaluable. The mean sense of coherence score was M = 47.30. Significant associations were shown for sense of coherence and financial situation (r = 0.230, p < 0.001), level of education (r = 0.187, p < 0.001), marital status (η = 0.177, p = 0.026) and time interval since diagnosis (r = - 0.109, p = 0.045). Sense of coherence and resilience correlated on a high level, as well as spirituality, self-efficacy and general life satisfaction (r = 0.563, r = 0.432, r = 0.461, r = 0.306, p's < 0.001)., Conclusion: Several aspects, such as demographics and psychological factors, have a great influence on the sense of coherence. To help patients to cope better, physicians should try to strengthen sense of coherence, resilience and self-efficacy and, at the same time, consider patients' individual background such as level of education, financial capacity and emotional support by family members., (© 2023.

- Abstract
Summary The S3-guideline on endometrial cancer, first published in April 2018, was reviewed in its entirety between April 2020 and January 2022 and updated. The review was carried out at the request of German Cancer Aid as part of the Oncology Guidelines Program and the lead coordinators were the German Society for Gynecology and Obstetrics (DGGG), the Gynecology Oncology Working Group (AGO) of the German Cancer Society (DKG) and the German Cancer Aid (DKH). The guideline update was based on a systematic search and assessment of the literature published between 2016 and 2020. All statements, recommendations and background texts were reviewed and either confirmed or amended. New statements and recommendations were included where necessary. Aim The use of evidence-based risk-adapted therapies to treat low-risk women with endometrial cancer prevents unnecessarily radical surgery and avoids non-beneficial adjuvant radiation therapy and/or chemotherapy. For women with endometrial cancer and a high risk of recurrence, the guideline defines the optimum level of radical surgery and indicates whether chemotherapy and/or adjuvant radiation therapy is necessary. This should improve the survival rates and quality of life of these patients. The S3-guideline on endometrial cancer and the quality indicators based on the guideline aim to provide the basis for the work of certified gynecological cancer centers. Methods The guideline was first compiled in 2018 in accordance with the requirements for S3-level guidelines and was updated in 2022. The update included an adaptation of the source guidelines identified using the German Instrument for Methodological Guideline Appraisal (DELBI). The update also used evidence reviews which were created based on selected literature obtained from systematic searches in selected literature databases using the PICO process. The Clinical Guidelines Service Group was tasked with carrying out a systematic search and assessment of the literature. Their results were used by interdisciplinary working groups as a basis for developing suggestions for recommendations and statements which were then modified during structured online consensus conferences and/or additionally amended online using the DELPHI process to achieve a consensus. Recommendations Part 2 of this short version of the guideline provides recommendations on the treatment of precancerous lesions and early-stage endometrial cancer, surgical treatment, radiotherapy and drug-based therapy, follow-up, recurrence, and metastasis of endometrial cancer as well as the state of psycho-oncological care, palliative care, patient education, rehabilitative and physiotherapeutic care., Competing Interests: Conflict of Interest/Interessenkonflikt The conflicts of interest of the authors are listed in the long German-language version of the guideline.

- Abstract
Background: The usage of complementary and alternative medicine (CAM) is widespread among cancer patients. While reasons for and aims of using CAM have been evaluated in many studies, less is known about whether patients' concepts of how and why cancer develops has an influence on the choice of the CAM method., Methods: We pooled the data from all studies of our working group containing questions on lay etiological concepts and CAM usage and reanalyzed them with respect to the associations between these parameters., Results: The pooled dataset from 12 studies included 4792 patients. A third (1645 patients) reported using CAM. Most often used were supplements (55.9%), relaxation techniques (43.6%), and homeopathy (37.9%). Regarding perceived causes, patients most often marked stress (35.4%) followed by genes (31.9%). While all lay etiological beliefs were highly significantly associated with usage of CAM in general, there was no association between single lay etiological concepts and types of CAM used. Yet, in a network analysis, we found two associations: one comprising trauma, mistletoe, genes, and nutritional supplements, the other yoga, vitamin C, nutritional supplements, and TCM herbs. In the correlation heatmap, one cluster comprises etiological concepts of personality, immune system and trauma, and two clusters of CAM methods emerged: one comprising praying, yoga, meditation, and relaxation procedures, the other nutritional supplements, selenium, vitamins A and C., Conclusion: While physicians are trained to derive treatment strategies from etiological concepts, lay people choosing CAM do not follow these rules, which may point to other needs of patients addressed by CAM., (© 2023.

- Abstract
Background: Being diagnosed with cancer is challenging. Many patients wish to be actively involved in treatment and contribute to therapy, but the patients' coping abilities and desire for involvement differ. The individual level of resilience seems to play a major role. Our study aims to learn more about the associations of resilience and factors as demographics and psychological factors., Methods: This multicentric cross-sectional study was conducted in ten oncological centers in Germany in summer 2021. The questionnaire collected information on demographics, resilience, self-efficacy, general satisfaction with life, and sense of coherence. Considered lifestyle-aspects were diet and physical activity. 416 patients were included in the analyses., Results: A moderate mean resilience score was achieved (M = 69). Significant correlations in demographics were found for resilience and education (r = 0.146, p = 0.003), income (r = 0.205, p = 0.001), and time since receiving diagnosis (r = - 0.115, p = 0.021). Resilience and self-efficacy correlated on a high level (r = 0.595, p < 0.001), resilience and sense of coherence, and resilience and general satisfaction with life in a moderate way (r = 0.339, p < 0.001; r = 0.461, p = 0.001)., Conclusions: Resilience portrays an important aspect in cancer treatment. Detecting patients at risk, stabilizing, or improving resilience are important to focus on and strengthen them accordingly. Possible negatively influencing factors (e.g., low self-efficacy) need to be considered. Factors affecting resilience but difficult to influence, as educational background, should be screened for. Also, the combination of low resilience and low income seems to describe a vulnerable patient group., (© 2022. The Author(s).)

- Abstract
Background: Approximately half of all cancer patients use complementary or alternative medicine., Aim: The results of the German S3 guidelines on complementary oncology are presented and placed into the context of patient consultation., Material and Methods: The core recommendations of the S3 guidelines are summarized including an overview of the evidence., Results: Selected methods of complementary medicine can be used with the aim of improving the quality of life and reducing side effects. Comprehensive data are available for physical activity with respect to survival, quality of life and supportive therapy. For most other methods the evidence is relatively low. Therefore, weighing up the benefits and risks more frequently resulted in negative recommendations in the guidelines, especially for methods based on substances. Exceptions to this are three micronutrients (vitamins B12, D and selenium), as even in the case of a well-balanced diet, deficiency symptoms are possible. Therefore, routine measurement of the blood levels of these micronutrients is recommended., Conclusion: The questions from patients on what they can do by themselves should be answered respectfully and based on evidence. The benefits and risks of complementary methods must be carefully considered. To do this, regular questioning of patients on the interest in complementary methods is recommended. The decisive benefit of complementary medicine is the chance for patients to become active themselves. Therefore, all recommendations refer to the discussion with the patient, which do not formulate a therapy but are consultation recommendations: should be recommended instead of should be done., (© 2022.

- Abstract
Background/aim: People who are undergoing cancer treatment often ask themselves what they can do in addition to conventional medical therapy with regard to nutrition, activity, and complementary methods. However, we know little about the motivation why people opt for one or the other measure. The aim of this study was therefore to examine the extent of physical activity (PA), healthy nutrition, and the use of complementary methods in relation to both demographic and psychological data., Materials and Methods: A questionnaire was used to collect data on demographic data, resilience, coherence, self-efficacy, spirituality, satisfaction, and complementary and alternative medicine (CAM) behavior, PA, and diet. Between March and July 2021, data from 446 patients were collected. Regression models and correlation analyzes were used to examine the associations between CAM use, diet and PA with the other variables surveyed., Results: CAM usage could only be predicted based on the patient's spirituality. Women used CAM more often and ate more healthily. Healthy eating was also related to younger age, shorter medical history, resilience, satisfaction, and coherence. In addition, the results showed that daily PA was related to the level of resilience, spirituality, and self-efficacy., Conclusion: Which people or why patients use CAM remains a question to be further investigated. Our data suggest that CAM seeks to address similar needs that others find in spirituality. In order to promote a healthy diet and PA in cancer patients in the future, various psychological variables seem conceivable. Resilience stands out, which is related to an overall healthier lifestyle., (Copyright © 2023, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.)

- Abstract
Background: Approximately half of all patients with cancer use at least one method of complementary medicine during or after tumor treatment. The substances most commonly taken are micronutrients, food supplements, and plant extracts., Methods: This guideline is based on pertinent articles retrieved by a systematic search in the Medline, Cochrane Library, Embase, PsycInfo, and Cinahl databases., Results: The evidence is offen scant for any effect of a complementary method on patient-relevant endpoints such as relief of disease symptoms, reduction of treatment side effects, or prolonged survival. Micronutrients are available in different compositions, and their dosages vary. In most studies on the use of vitamins and trace elements by cancer patients, the blood level of the substance in question was not measured before its administration, so that it remains unknown whether a deficiency was present. For this reason, no well-founded conclusion on the effects of these substances can be drawn, and their use cannot be recommended in most cases. On the other hand, there is high-level evidence supporting physical exercise by cancer patients during and after their treatment. For patients with any type of cancer, mortality is lower among those who perform more physical exercise, whether before or after they receive the diagnosis of cancer (exercise before diagnosis, hazard ratio [HR] 0.82, 95% confidence interval [CI] [0.79; 0.86]; exercise after diagnosis, HR 0.63, 95% CI [0.53; 0.75]). Physical exercise during and after treatment for cancer should, therefore, be recommended to all cancer patients., Conclusion: The inherent positive attribute of complementary medicine is patient empowerment: it enables patients to help themselves in an active way even while undergoing cancer treatment, as well as afterward. To avoid risks to health, patients should be instructed about unsafe methods, asked repeatedly about their use of complementary medicine, and informed specifically about potential interactions between such interventions and their cancer treatment.

- Abstract
Salivary glands carcinomas are very rare epithelial malignant tumors. In 2013 in Europe, 7800 new diagnoses were estimated, 8.5 % of all head and neck cancer. The last WHO classification (2017) counts more than 20 malignant histotypes, this variety as well as the rarity of some of them needs a skilled pathologist for diagnosis. Surgery remains the mainstay of management followed by radiation in high-grade and high-risk pathological features cases. The intensity modulated radiotherapy (IMRT) should be preferred over conformational radiotherapy techniques as adjuvant and exclusive treatment in advanced cases. Particle radiotherapy (i.e. protons, carbon ions) can have a role in advanced/unresectable disease since it was proved to have better results over photons in loco-regional control both in adenoid cystic carcinoma and in other histotypes. Although chemotherapy is still the most frequent treatment for metastatic patients, several new compounds (i.e. anti-angiogenic agents, tailored agents, checkpoint inhibitors) are under investigation., Competing Interests: Declaration of Competing Interest L.D.L. reports grant and other financial relationship with Eisai, Ipsen, Merck Serono, MSD, BMS, Lilly and Biogen; the other authors declare they have no conflict of interest., (Copyright © 2020 Elsevier B.V.

- Abstract
Background: Data on patients' needs with respect to physicians' ethical behavior and virtues are important but not available in most cases., Patients and Methods: In an iterative process together with patients' representatives, we developed a standardized questionnaire which was distributed to the representatives of the Women's Self-Help after Cancer in Germany. We started with the classical ethical virtues and clustered them to characteristics. The patients' representatives were asked to rate in different communications settings., Results: One hundred eighty-six patients' representatives took part in the survey. For four communication situations (first communication on symptoms, diagnosis of cancer, choice of therapy, doubts on therapy), competence was rated as very important by 80-89% and as important by 6-7%; honesty as very important by 78-89% and as important by 5-12%; respect as very important by 66-71% and as important by 19-21%; and patience as very important by 55-68% and as important by 6-24%. Compassion was rated as less important, with only 24-31% rating it as very important and another 26-32% as important. Additional desires expressed by the participants were physicians having more time (9.1%) and a better relationship between physician and patient (7.0%)., Conclusion: Competence, honesty, respect, and patience are important characteristics which should be focused on in communication training of medical students and physicians. In spite of compassion being rated as less important, training on compassion/empathy might help doctors to improve coping with the continuous confrontation with complications, progress, suffering, and death of their patients.

- Abstract
Summary The first German interdisciplinary S3-guideline on the diagnosis, therapy and follow-up of patients with endometrial cancer was published in April 2018. Funded by German Cancer Aid as part of an Oncology Guidelines Program, the lead coordinators of the guideline were the German Society of Gynecology and Obstetrics (DGGG) and the Gynecological Oncology Working Group (AGO) of the German Cancer Society (DKG). Purpose Using evidence-based, risk-adapted therapy to treat low-risk women with endometrial cancer avoids unnecessarily radical surgery and non-useful adjuvant radiotherapy and/or chemotherapy. This can significantly reduce therapy-induced morbidity and improve the patient's quality of life as well as avoiding unnecessary costs. For women with endometrial cancer and a high risk of recurrence, the guideline defines the optimal extent of surgical radicality together with the appropriate chemotherapy and/or adjuvant radiotherapy if required. An evidence-based optimal use of different therapeutic modalities should improve the survival rates and quality of life of these patients. This S3-guideline on endometrial cancer is intended as a basis for certified gynecological cancer centers. The aim is that the quality indicators established in this guideline will be incorporated in the certification processes of these centers. Methods The guideline was compiled in accordance with the requirements for S3-level guidelines. This includes, in the first instance, the adaptation of source guidelines selected using the DELBI instrument for appraising guidelines.

- Abstract
Summary The first German interdisciplinary S3-guideline on the diagnosis, therapy and follow-up of patients with endometrial cancer was published in April 2018. Funded by German Cancer Aid as part of an Oncology Guidelines Program, the lead coordinators of the guideline were the German Society of Gynecology and Obstetrics (DGGG) and the Gynecological Oncology Working Group (AGO) of the German Cancer Society (DKG). Purpose The use of evidence-based, risk-adapted therapy to treat low-risk women with endometrial cancer avoids unnecessarily radical surgery and non-useful adjuvant radiotherapy and/or chemotherapy. This can significantly reduce therapy-induced morbidity and improve the patient's quality of life as well as avoiding unnecessary costs. For women with endometrial cancer and a high risk of recurrence, the guideline defines the optimal surgical radicality together with the appropriate chemotherapy and/or adjuvant radiotherapy where required. The evidence-based optimal use of different therapeutic modalities should improve survival rates and the quality of life of these patients. The S3-guideline on endometrial cancer is intended as a basis for certified gynecological cancer centers. The aim is that the quality indicators established in this guideline will be incorporated in the certification processes of these centers. Methods The guideline was compiled in accordance with the requirements for S3-level guidelines. This includes, in the first instance, the adaptation of source guidelines selected using the DELBI instrument for appraising guidelines. Other consulted sources include reviews of evidence which were compiled from literature selected during systematic searches of literature databases using the PICO scheme. In addition, an external biostatistics institute was commissioned to carry out a systematic search and assessment of the literature for one area of the guideline. The identified materials were used by the interdisciplinary working groups to develop suggestions for Recommendations and Statements, which were then modified during structured consensus conferences and/or additionally amended online using the DELPHI method with consent being reached online. The guideline report is freely available online. Recommendations Part 1 of this short version of the guideline presents recommendations on epidemiology, screening, diagnosis and hereditary factors, The epidemiology of endometrial cancer and the risk factors for developing endomentrial cancer are presented. The options for screening and the methods used to diagnose endometrial cancer including the pathology of the cancer are outlined. Recommendations are given for the prevention, diagnosis, and therapy of hereditary forms of endometrial cancer.

- Abstract
Background: The standard treatment for muscle-invasive bladder cancer is radical cystectomy with pelvic lymphadenectomy. Primary organ-preservation by means of multimodal therapy, however, can be a viable alternative to radical surgery., Objectives: The concept and results of multimodal therapy, consisting of initial transurethral resection of the bladder tumor (TUR-B), followed by simultaneous radiochemotherapy (RCT), are presented., Materials and Methods: Evaluation of retrospective cohorts and prospective therapy optimization studies on organ-preservation treatment regimens. Comparative meta-analyses comparing cystectomy with multimodal treatment are presented., Results: Complete TUR-B, including bladder mapping and tumor biopsy, should precede simultaneous RCT. Radiosensitization should be cisplatin-based or consist of a combination of 5‑fluorouracil and mitomycin C. Complete response rates after TUR-B plus RCT are generated in 60-90% of patients along with 5‑year survival rates of 40-75% and preservation of the bladder in approximately 80% of surviving patients., Conclusions: Multimodal therapy by means of TUR-B followed by simultaneous RCT is a viable alternative to radical cystectomy for patients with muscle-invasive urinary bladder carcinoma. Patients with early tumors (cT2/3N0) are particularly suitable in whom initial TUR-B leads to complete tumor resection (R0).

- Abstract
Objective: To analyze the financial burden of complementary and alternative medicine (CAM) in cancer treatment., Materials and Methods: Based on a systematic search of the literature (Medline and the Cochrane Library, combining the MeSH terms 'complementary therapies', 'neoplasms', 'costs', 'cost analysis', and 'cost-benefit analysis'), an expert panel discussed different types of analyses and their significance for CAM in oncology., Results: Of 755 publications, 43 met our criteria. The types of economic analyses and their parameters discussed for CAM in oncology were cost, cost-benefit, cost-effectiveness, and cost-utility analyses. Only a few articles included arguments in favor of or against these different methods, and only a few arguments were specific for CAM because most CAM methods address a broad range of treatment aim parameters to assess effectiveness and are hard to define. Additionally, the choice of comparative treatments is difficult. To evaluate utility, healthy subjects may not be adequate as patients with a life-threatening disease and may be judged differently, especially with respect to a holistic treatment approach. We did not find any arguments in the literature that were directed at the economic analysis of CAM in oncology. Therefore, a comprehensive approach assessment based on criteria from evidence-based medicine evaluating direct and indirect costs is recommended., Conclusion: The usual approaches to conventional medicine to assess costs, benefits, and effectiveness seem adequate in the field of CAM in oncology. Additionally, a thorough deliberation on the comparator, endpoints, and instruments is mandatory for designing studies., (© 2016 S. Karger AG, Basel.)

- Abstract
Purpose: Many cancer patients use complementary and alternative medicine (CAM) during or after their therapy. Because little is known about CAM in palliative care, we conducted 2 surveys among patients and professionals in the palliative setting., Participants and Methods: Patients of a German Comprehensive Cancer Center were interviewed, and an independent online survey was conducted among members of the German Society for Palliative Care (DGP)., Results: In all, 25 patients and 365 professional members of the DGP completed the survey (9.8% of all members); 40% of the patients, 85% of the physicians, and 99% of the nurses claimed to be interested in CAM. The most important source of information for professionals is education, whereas for patients it is radio, TV, and family and friends. Most patients are interested in biological-based methods, yet professionals prefer mind-body-based methods. Patients more often confirm scientific evidence to be important for CAM than professionals., Conclusions: To improve communication, physicians should be trained in evidence for those CAM methods in which patients are interested., (© The Author(s) 2015.)

- Abstract
Background: Endocrine therapy is a mainstay of prostate cancer therapy. Given that few data exist on patient physician communication with regard to this field of therapy and adherence, we conducted a survey of patient members of a German support organization., Patients and Methods: We developed a structured questionnaire that was tested in a pilot version and then programmed as an online questionnaire., Results: The questionnaire was completed by 694 patients. While 58 % of participants rated the information they received as comprehensive, 42 % did not. Fifty-one percentage stated that they were informed of side effects in detail, and 35 % received information on supportive treatments available in the event of side effects. Patients with higher education more often reported receiving information on side effects (p = 0.036) as well as alternatives for treatment (p = 0.001). Only 13 % stated that their questions were answered in detail, with 43 % receiving no answers or only non-detailed answers. Additional information was sought by 82 %, mostly from the Internet (67 %) and patient support groups (66 %). Seventy-six percentage experienced side effects that imposed limitations on their daily activities. Of those patients with side effects, 60 % reported that their physicians did not react to their complaints. There is a significant association between side effects in general and depression in particular and non-adherence (p < 0.01 and p = 0.002, respectively). In contrast, better information on side effects is associated with better adherence (p < 0001)., Conclusion: In order to improve adherence, detailed information on side effects and comprehensive supportive care is most important. Physicians should not rely on written information but should rather mainly engage in direct communication.

- Abstract
About half of all patients with cancer use complementary or alternative medicine (CAM). In 2013, we started a lecture program for patients, followed by evidence-based recommendations on counseling on CAM. These recommendations have been published before by this working group. The aim of the program is to provide scientific facts on the most often used CAM methods in standardized presentations which help patients discuss the topic with their oncologists and support shared decision making. The article presents the evaluation of the pilot phase. Participants received a standardized questionnaire before the start of the lecture. The questionnaire comprises four parts: demographic data, data concerning experience with CAM, satisfaction with the lecture, and needs for further information on CAM. In 2013, seven lectures on CAM were given in cooperation with regional branches of the German Cancer Society in several German states. Four hundred sixty patients and relatives took part (75% females and 16% males). Forty-eight percent formerly had used CAM. Most often named sources of information on CAM were print media (48%) and the Internet (37%). Most participants rated additional written information valuable. About one third would like to have an individual consultation concerning CAM. A standardized presentation of evidence on CAM methods most often used, together with recommendations on the self-management of symptoms, is highly appreciated. The concept of a highly interactive lecture comprising is feasible and if presented in lay terminology, adequate. In order to give additional support on the topic, written information should be provided as the first step.

- Abstract
Background and Purpose: Physical 3D treatment planning provides a pool of parameters describing dose distributions. It is often useful to define conformal indices to enable quicker evaluation. However, the application of individual indices is controversial and not always effective. The aim of this study was to design a quick check of dose distributions based on several indices detecting underdosages within planning target volumes (PTVs) and overdosages in normal tissue., Materials and Methods: Dose distributions of 215 cancer patients were considered. Treatment modalities used were three-dimensional conformal radiotherapy (3DCRT), radiosurgery, intensity-modulated radiotherapy (IMRT), intensity-modulated arc therapy (IMAT) and tomotherapy. The volumes recommended in ICRU 50 and 83 were used for planning and six conformation and homogeneity indices were selected: CI, CN, CICRU, COV, C∆, and HI. These were based on the PTV, the partial volume covered by the prescribed isodose (PI; PTVPI), the treated volume (TVPI), near maximum D2 and near minimum D98. Results were presented as a hexagon-the corners of which represent the values of the indices-and a modified test function F (Rosenbrock's function) was calculated. Results refer to clinical examples and mean values, in order to allow evaluation of the power of F and hexagon-based decision support procedures in detail and in general., Results: IMAT and tomotherapy showed the best values for the indices and the lowest standard deviation followed by static IMRT. DCRT and radiosurgery (e.g. CN: IMAT 0.85 ± 0.06; tomotherapy 0.84 ± 0.06; IMRT 0.83 ± 0.07; 3DCRT 0.65 ± 0.08; radiosurgery 0.64 ± 0.11). In extreme situations, not all indices reflected the situation correctly. Over- and underdosing of PTV and normal tissue could be qualitatively assessed from the distortion of the hexagon in graphic analysis. Tomotherapy, IMRT, IMAT, 3DCRT and radiosurgery showed increasingly distorted hexagons, the type of distortion indicating exposure of normal tissue volumes. The calculated F values correlated with these observations., Conclusion: An evaluation of dose distributions cannot be based on a single conformal index. A solution could be the use of several indices presented as a hexagonal graphic and/or as a test function.

- Abstract
Background: A high proportion of cancer patients use complementary and alternative medicine (CAM). In oncology, risks of CAM are side effects and interactions., Objective: Our aim was to conduct a survey on professionals in palliative care regarding attitudes toward CAM., Design and Subjects: An internet-based survey with a standardized questionnaire was sent to all members of the German Society for Palliative Care., Measurements: The questionnaire collected data on attitude toward CAM and experiences., Results: Six hundred and ninety questionnaires (19 %) were returned (49 % physicians, 35 % nurses, 3 % psychologists). Acceptance of CAM is high (92 % for complementary and 54 % for alternative medicine). Most participants had already been asked on CAM by patients (95 %) and relatives (89 %). Forty-four percent already had used complementary methods and 5 % alternative methods. Only 21 % think themselves adequately informed. Seventy-four percent would use complementary methods in a patient with advanced tumor, and 62 % would use alternative therapy in patients if there was no other therapy. Even from those who are skeptical 45 % would treat a patient with alternative methods., Conclusions: In order to inform patients on CAM and to further patients' autonomy, evidence on benefits and harms of CAM must be provided. As awareness of risks from CAM is low and critical appraisal especially of alternative medicine missing, but interest on information on CAM is high, experts should provide evidence-based recommendations for CAM in palliative care to members of different professions. This could be done by a curriculum focusing on the most often used CAM methods.

- Abstract
Patient-reported outcomes are an important tool in clinical research. In the setting of cancer treatments, benefit of therapy is essentially characterised by improvement of survival as well as quality of life (QoL). A standardised instrument to assess QoL is the standardised QoL questionnaire of the European Organisation for Research and Treatment (EORTC QLQ-C30 questionnaire). QoL instruments provide data on different aspects (domains) of the framework of QoL. Using these questionnaires in studies provides data on how a treatment affects QoL in a group of patients. The goal of our concept is to individualise QoL and to use validated instruments in order to integrate patients' perspectives and aims into treatment assessment, planning and control. We propose to use the domains of the EORTC QLQ-C30 and to ask the patient to determine which objectives besides survival are relevant for him and should be achieved by treatment. These individual goals can be used in a process of shared decision-making to choose and monitor treatment. In clinical studies, this approach would allow to recruit more patients who would most probably benefit from the therapy. In addition, supportive data could be gathered in correlation to treatment goals and actual benefits., (© 2013 John Wiley & Sons Ltd.)

- Abstract
About 50% of cancer patients use complementary and alternative medicine (CAM). Women with breast cancer use CAM more frequently than others. We linked a questionnaire to the largest internet portal for cancer patients in Germany. The questionnaire addresses attitude towards CAM, disclosure to the oncologist, source of information, and objectives for use of CAM. 80 patients with breast cancer took part in our study, 61 currently using CAM. Most frequently used CAM methods were selenium, relaxation techniques, prayer, vitamin C, and meditation. Satisfaction was highest with relaxation techniques, vitamin C, homeopathy, yoga and Chinese herbs, lowest with mistletoe and acupuncture. 70% of participants did not think their oncologist took time to discuss CAM. Only 16% believed that their oncologist was well-informed about CAM. 46% relied on naturopaths and non-medical practitioners concerning CAM. Objectives for the use of CAM were to reduce side effects, boost the immune system, and become active.

- Abstract
Background: In Europe about 40% to 50% of patients with cancer use complementary or alternative medicine (CAM). Only scarce data regarding the use of CAM have been reported from comprehensive cancer Centers., Patients and Methods: We carried out a survey on patients attending the counseling Unit for CAM of a German comprehensive cancer Center using a standardized questionnaire., Results: A total of 165 patients participated in the survey; 60% had already used CAM. Trace elements and vitamins were most often used. Strengthening oneself and one's immune system were the two main reasons (73% and 69% respectively for CAM use). The most important sources of information are print media and physicians (41% and 35% respectively). The two main reasons for using CAM were practitioners spending more time with patients and patients having experienced positive effects from CAM., Conclusion: For patients with cancer becoming active is an important goal, while disappointment in conventional medicine is not. Accepting patients' motivation for autonomy may help oncologists to increase adherence to conventional therapy.

- Abstract
Background: In total, 40-70% of cancer patients use complementary or alternative medicine (CAM). Many of them ask for advice from non-medical practitioners (NMPs). Our aim was to investigate the attitude of NMPs regarding their treatments for cancer patients., Methods: A survey was performed on members of NMP associations, using an online questionnaire on diagnosis and treatment, goals for using CAM, communication with the oncologist, and sources of information., Results: Of the 1,500 members of the NMP associations, 299 took part. The treatments were found to be heterogeneous. Homeopathy is used by 45% of the NMPs; 10% believe it to be a treatment directly against cancer. Herbal therapy, vitamins, orthomolecular medicine, ordinal therapy, mistletoe preparations, acupuncture, and cancer diets are used by more than 10% of the NMPs. None of the treatments is discussed with the respective physician on a regular basis., Conclusions: Many therapies provided by NMPs are biologically based and therefore may interfere with conventional cancer therapy. Thus, patients are at risk of interactions, especially as most NMPs do not adjust their therapies to those of the oncologist. Moreover, risks may arise from these CAM methods as NMPs partly believe them to be useful anticancer treatments. This may lead to the delay or even omission of effective therapies., (© 2014 S.

- Abstract
Introduction: Complementary and alternative medicine (CAM) is often used by cancer patients, yet, communication with the oncologist is poor. The objective of our study was to gather information on patients' usage of CAM, source of information, and aims, in order to derive strategies to improve the communication between physicians and patients on this topic., Materials and Methods: An online survey was conducted by linking a standardized questionnaire to the largest internet portal for cancer patients in Germany. The questionnaire addresses CAM usage, disclosure to physicians, source of information, objectives for using CAM, and perceived reasons for cancer., Results: Of 170 participants, 77% were currently using CAM. Disclosure to a physician was rather high with 63% having informed their oncologist. Asked whether the oncologist took time to discuss CAM, 74% answered 'no'. Most frequently used are biologically based therapies, relaxation techniques, prayer, and meditation. Most patients want to reduce side effects, boost their immune system, and get active. Almost half the participants had positive experiences with some type of CAM before they fell ill., Conclusion: Understanding patients' concepts of the etiology of cancer and accepting their goals for using CAM may help oncologists communicate with their patients and guide them to a safe use of CAM., (© 2014 S.

- Abstract
Background: Cancer patients often use complementary and alternative medicine (CAM), yet discussion with the oncologist is often missing and oncologists lack knowledge in CAM., Patients and Methods: In order to learn more about the attitude of professionals in oncology toward CAM, a survey was conducted on employees of a German university clinic using a structured questionnaire., Results: In total, 547 employees took part in the survey. One-third would definitely use CAM on cancer patients. Female employees are more interested in CAM than males (80% versus 20%; P = 0.001); physicians are less interested than nurses (57% versus 72%; P = 0.008). 2.5% of physicians and 9% of nurses are convinced that CAM is as effective as conventional therapy in cancer. Fifty-two percent of physicians and 12% of nurses agree that adverse effects due to CAM may be possible. Seventy-three percent did not consider themselves adequately informed on CAM for their professional work., Conclusions: As a substantial part of participants would use CAM on cancer patients and most are interested in but not trained on this topic, there is a need for training of professionals from different professions working in oncology.

- Abstract
Purpose: A total of 40 % of cancer patients use complementary and alternative medicine (CAM), and patients with advanced cancer use CAM more often than others. The aim of our study was to gather data on CAM use and reasons to use CAM of patients with advanced cancer being admitted for residential palliative care and their relatives., Methods: Structured interviews were carried out with 25 patients and 25 relatives of those patients, respectively, of a German comprehensive cancer center based on a standardized questionnaire of the working group Prevention and Integrative Oncology of the German Cancer Society., Results: Median age of patients was 64.5 years (relatives: 53.5); 15 patients were male and 10 were female (relatives: 7 and 18). In total, 40 % of all patients used some CAM method at the time of the study, supplements and prayer being the most frequent method. Main reasons for using CAM were to sustain one's own strength (52 % for patients and 72 % for relatives) and to be able to do something by oneself (36 and 40 %). Sources of information were television/radio (48 and 28 %) and family/friends (40 and 48 %). Relatives also use the Internet (40 %)., Conclusions: Also for patients in palliative care and their relatives, CAM is important. Reasons for using CAM are similar for patients with less advanced cancer. As most patients do not discuss using CAM with their physician, side effects and interactions of biologically based treatments may be dangerous. The desire of patients to act autonomously should be encouraged. Yet, physicians should ensure safe administration of complementary methods by including CAM in their communication with the patient and the family.

Background and Purpose: Complementary and alternative medicine (CAM) is of high relevance in oncology. Only a minority of professionals feel competent in CAM. Our aim was to provide a strategy for establishing evidence-based counseling on CAM in oncology in the German health system., Methods: We performed a systematic search of the literature on patient counseling concerning CAM. Of 811 articles identified in this search 51 met our inclusion criteria. Data from these articles were analyzed and adapted to the needs of German patients by a group of experts of the DEGRO ("Deutschen Gesellschaft für Radioonkologie") and the German Cancer Society. In the next step a strategy about how to integrate evidence-based counseling on CAM at cancer centers and oncological institutions was developed., Results: First, evidence-based recommendations on CAM counseling were derived. The core of our strategy combines two levels of information provision: level 1 will be oncologists, radiotherapists and other specialists and level 2 oncological CAM experts. The latter group will serve as trainers and backup for complicated or advanced questions and for individual counseling of patients with complex needs. Professionals in level 1 will be offered special training., Conclusion: Evidence-based counseling on CAM is not only possible but also mandatory in order to meet patient information needs. Our proposal would allow for integrated counseling available at all oncological institutions and guarantee a high quality. Furthermore, provision of information on two different levels allows the effective use of resources (manpower and financing).

- Abstract
Purpose: Many cancer patients use complementary and alternative medicine (CAM). However, data in hematological cancers are lacking on which types of CAM are being used, what information sources on CAM patients use and to what extent CAM is being addressed in the consultation with the hematologist., Methods: We developed a standardized questionnaire on CAM which was provided online to the representatives of the worldwide Chronic Myeloid Leukemia Advocates Network., Results: A total of 53 leaders of patients' advocacy groups for chronic myeloid leukemia (CML) patients from 35 countries responded to the survey. In almost all countries, CAM is important for CML patients and is widely used in addition to conventional leukemia treatment. Mostly, patients have to pay by themselves. General practitioners, herbalists, healers and naturopaths are the main sources for CAM treatments. Information on CAM is derived most frequently from the Internet, and family and friends, but rarely provided by the oncologist. Disclosure of CAM use to the oncologist is low, but increases if oncologists offer CAM., Conclusions: In spite of very different health care systems, the features of CAM usage are similar in the different countries. We suggest extending the cooperation of self-help and scientists in order to provide training of oncologists on CAM and quality-controlled, evidence-based information on CAM on the Internet both for patients as well as health professionals as a promising strategy to increase safe use of CAM in patients with CML.

- Abstract
Background: In a previous analysis (Int J Radiat Oncol Biol Phys 70:828-835,2010), we assessed whether an adjuvant supplementation with selenium (Se) improves Se status and reduces the radiation-induced side-effects of patients treated by adjuvant radiotherapy (RT) for cervical and uterine cancer. Now, a potential relation between the planning target volume (PTV) of the RT and the Se effect concerning radiation induced diarrhoea was evaluated in detail., Methods: Whole blood Se concentrations had been measured in patients with cervical (n=11) and uterine cancer (n=70) after surgical treatment, during, and at the end of RT. Patients with initial Se concentrations of less than 84 μg/l were categorized as Se-deficient and randomized before RT to receive Se (as sodium selenite) per os on the days of RT, or to receive no supplement during RT. Diarrhoea was graded according to the Common Toxicity Criteria system (CTC, Version 2a). The evaluation of the PTV of the RT was ascertained with the help of a specialised computer-assisted treatment planning software used for radiation planning procedure., Results: A total of 81 patients had been randomized for the initial supplementation study, 39 of which received Se [selenium group, SeG] and 42 serving as controls [control group, CG]. Mean Se levels did not differ between SeG and CG upon study initiation, but were significantly higher in the SeG compared to the CG at the end of RT. The actuarial incidence of at least CTC 2 radiation induced diarrhoea in the SeG was 20.5% compared to 44.5% in the CG (p=0.04). The median PTV in both groups was 1302 ml (916-4608). With a PTV of <= 1302 ml (n=41) the actuarial incidence of at least CTC 2 diarrhoea in the SeG was 22.3% (4 of 18 patients) compared to 34.8% (8 of 23 patients) in the CG (p=0.50). In patients with a PTV of > 1302 ml (n=40) the actuarial incidence of at least CTC 2 diarrhoea in the SeG was 19.1% (4 of 21 patients) versus 52.6% (10 of 19 patients) in the CG (p=0.046)., Conclusions: Se supplementation during RT was effective to improve blood Se status in Se-deficient cervical and uterine cancer patients, and reduces episodes and severity of RT-induced diarrhoea. This effect was most pronounced and significant in patients with large PTV (> 1302 ml).

- Abstract
Background: Many cancer patients use complementary and alternative medicine (CAM). Most websites offering online information on CAM are not helpful for them., Methods: We extracted decisive elements for online information on CAM by analyzing the literature on the information needs of cancer patients and on counseling cancer patients on CAM., Results: Key issues for online information on CAM are the qualification of the authors, transparency and accountability of the information, description of the aims, a scientific approach, description of treatment alternatives, support for the patient-physician relationship, individualized information, a summary of the information, disclosure of funding, and the privacy policy., Conclusions: The communicative challenge will be to convey information without destroying hope and motivation. We suggest that CAM topics should be integrated into broader information provided on cancer (etiology, conventional treatment). By also providing information for physicians, such a website could promote shared decision-making. Online information will gain the status of independent expert knowledge if provided by a well-known scientific organization as, e.g., a national cancer society., (Copyright © 2013 S.

- Abstract
Purpose: We assessed whether adjuvant supplementation with selenium improves the selenium status and reduces side effects of patients treated by radiotherapy (RT) for cervical and uterine cancer., Methods and Materials: Whole-blood selenium concentrations were measured in patients with cervical cancer (n = 11) and uterine cancer (n = 70) after surgical treatment, during RT, at the end of RT, and 6 weeks after RT. Patients with initial selenium concentrations of less than 84μg/L were randomized before RT either to receive 500 μg of selenium (in the form of sodium selenite [selenase, biosyn Arzneimittel GmbH, Fellbach, Germany]) by mouth on the days of RT and 300 μg of selenium on the days without RT or to receive no supplement during RT. The primary endpoint of this multicenter Phase 3 study was to assess the efficiency of selenium supplementation during RT; the secondary endpoint was to decrease radiation-induced diarrhea and other RT-dependent side effects., Results: A total of 81 patients were randomized. We enrolled 39 in the selenium group (SG) and 42 in the control group (CG). Selenium levels did not differ between the SG and CG upon study initiation but were significantly higher in the SG at the end of RT. The actuarial incidence of diarrhea of Grade 2 or higher according to Common Toxicity Criteria (version 2) in the SG was 20.5% compared with 44.5% in the CG (p = 0.04). Other blood parameters, Eastern Cooperative Oncology Group performance status, and self-reported quality of life were not different between the groups., Conclusions: Selenium supplementation during RT is effective in improving blood selenium status in selenium-deficient cervical and uterine cancer patients and reduces the number of episodes and severity of RT-induced diarrhea., (Copyright © 2010 Elsevier Inc.

- Abstract
Malignant salivary gland tumors are rare. The most common tumor site is the parotid. Aetiologic factors are not clear. Nutrition may be a risk factor, as well as irradiation or a long-standing histologically benign tumor that occurs at youth. Painless swelling of a salivary gland should always be considered as suspicious, especially if no sign of inflammation is present. Signs and symptoms related to major salivary gland tumors differ from those concerning minor salivary gland tumors, as they depend on the different location of the salivary gland. Surgical excision represents the standard option in the treatment of resectable tumors of both major and minor salivary glands. Neutron, heavy ions or proton radiotherapy may be a treatment option for inoperable locoregional disease. Surgery, irradiation or re-irradiation are treatment options for local relapse, whereas radical neck dissection is indicated for regional relapses. Metastatic disease may be either treated with radiotherapy or palliative chemotherapy, depending on the site of metastases. For highly selected patients the employment of anti-androgen therapy is indicated., (2009 Elsevier Ireland Ltd. All rights reserved.)

- Abstract
Background and Purpose: After a patterns-of-care study (PCS) in 2003/2004 addressing benign disorders in general, the German Cooperative Group on Radiotherapy for Benign Diseases (GCG-BD) conducted several multicenter cohort studies including the use of radiotherapy (RT) in painful gonarthrosis (GNA)., Material and Methods: From 2006 to 2008, a PCS for GNA was conducted in all German RT institutions using a standardized structured questionnaire. Patient accrual, patient number, pretreatment, pain record, treatment indications, RT technique, and target volume concepts for painful GNA were assessed. In addition, the long-term functional and subjective outcomes were evaluated., Results: 238/248 institutions (95.9%) returned the questionnaire: 50 (21%) reported no clinical experience with RT in GNA, while 188 (79%) institutions treated 4,544 patients annually (median 15; range one to 846 cases per institution). Indications for treatment were acute pain symptoms in 18.9%, chronic pain in 95.3%, and treatment-refractory pain in 81.1%. The median total dose was 6 Gy (range 3-12 Gy), with a median single dose of 1 Gy (0.25-3 Gy). 40.4% of the institutions applied two fractions and 51.4% three fractions weekly. RT was delivered with orthovoltage units (25%), linear accelerators (79.6%), and cobalt-60 units (8.3%). 42 institutions evaluated the long-term clinical outcome in a total of 5,069 cases. Median pain reduction for at least 3 months was reported in 60% (5-100%), median pain reduction for at least 12 months in 40% (10-100%), and median persistent pain reduction in 27.8% (10-85%) of the treated patients. In 30% of patients (7-100%), a second RT series was applied for inadequate pain response or early pain recurrence. No radiogenic acute or chronic side effects were observed., Conclusion: This PCS comprises the largest number of cases reported for RT in painful and refractory GNA. Despite variations in daily RT practice, high response and low toxicity for this treatment in a very large number of painful and refractory GNA cases renders low-dose RT an effective conservative therapy which can be applied prior to surgical procedures.

- Abstract
Purpose: To compare acute gastrointestinal (GI) and genitourinary (GU) toxicity between patient groups with localized prostate adenocarcinoma, treated with conventionally fractionated (CFRT) and hypofractionated (HFRT) three-dimensional conformal external-beam radiotherapy (3D-CRT)., Patients and Methods: 91 patients were enrolled into a randomized study with a minimum follow-up of 3 months. 44 men in the CFRT arm were irradiated with 74 Gy in 37 fractions at 2 Gy per fraction for 7.5 weeks. 47 men in the HFRT arm were treated with 57 Gy in 17 fractions for 3.5 weeks, given as 13 fractions of 3 Gy plus four fractions of 4.5 Gy. The clinical target volume (CTV) included the prostate and the base of seminal vesicles. The CTV-to-PTV (planning target volume) margin was 8-10 mm. Study patients had portal imaging and/or simulation performed on the first fractions and repeated at least weekly., Results: No acute grade 3 or 4 toxicities were observed. The grade 2 GU acute toxicity proportion was significantly lower in the HFRT arm: 19.1% versus 47.7% (chi(2)-test, p = 0.003). The grade 2 GU acute toxicity-free survival was significantly better in the HFRT arm (log-rank test, p = 0.008). The median duration of overall GI acute toxicity was shorter with HFRT: 3 compared to 6 weeks with CFRT (median test, p = 0.017)., Conclusion: In this first evaluation, the HFRT schedule is feasible and induces acceptable or even lower acute toxicity compared with the toxicities in the CFRT schedule. Extended follow-up is needed to justify this fractionation schedule's safety in the long term.

- Abstract
Background: The aim of this exploratory study was to evaluate whether significant differences exist between whole blood selenium levels (WBSL) in patients with prostate cancer (PC), benign prostatic hyperplasia (BPH), healthy male inhabitants (HMI) in northern Bavaria and the normal value. Furthermore, we investigated whether differences exist between prostatic tissue selenium levels (PTSL) in patients with PC, BPH and the benign tissue surrounding the PC., Material and Methods: We prospectively evaluated WBSL in 24 patients with PC, 21 patients with BPH, and 21 HMI. Measurements of PTSL were performed in 17 patients with PC and 22 patients with BPH. In 9 cases with PC, measurements were also done in the benign tissue surrounding the carcinoma. Measurements were performed using automated graphite furnace atomic absorption spectrophotometry., Results: In patients with PC, there is a significantly lower WBSL in comparison to HMI (p=0.04). There is no significant difference in WBSL between BPH-patients and HMI (p=0.13) and between PC- and BPH-patients (p=0.67). In all patients and the HMI, there is a significantly lower WBSL in comparison to the recommended normal value of 85-162 microg/l (p<0.01). There is no significant difference in PTSL between PC and BPH (p=0.49), and between PC and the tissue compartment surrounding the PC (p=0.56). PTSL seemed to be reduced in the compartment surrounding the PC in comparison to BPH (p=0.03). In PC-patients, there is no significant correlation between WBSL and prostate specific antigen (PSA) (? = -0.20; p=0.36), Gleason score (? = 0.32, p=0.13), and T-stage (? = 0.22; p=0.23)., Conclusion: Since the WBSL measured in all men with PC and BPH, and in HMI participating in our study were significantly lower than the recommended normal range, our findings may support the recommendation of selenium supplementation.

- Abstract
A total of 502 patients treated between 1990 and 2002 with low-dose radiotherapy (RT) for painful heel spurs were analysed for prognostic factors for long-term treatment success. The median follow-up was 26 months, ranging from 1 to 103 months. Events were defined as (1) slightly improved or unchanged pain after therapy, or (2) recurrent pain sensations during the follow-up period. Overall 8-year event-free probability was 60.9%. Event-free probabilities of patients with one/two series (414/88) were 69.7%/32.2% (p<0.001); >58/ < or = 58 years (236/266), 81.3%/47.9% (p=0.001); high voltage/orthovoltage (341/161), 67.9%/60.6% (p=0.019); pain anamnesis < or = 6 months/ >6 months (308/194), 76.3%/43.9% (p=0.001); single dose 0.5/1.0 Gy (100/401), 86.2%/55.1% (p=0.009); without/with prior treatment (121/381), 83.1%/54.9% (p=0.023); men/women (165/337), 61.2%/61.5% (p=0.059). The multivariate Cox regression analysis with inclusion of the number of treatment series, age, photon energy, pain history, single-dose and prior treatments revealed patients with only one treatment series (p<0.001), an age >58 years (p=0.011) and therapy with high voltage photons (p=0.050) to be significant prognostic factors for pain relief. Overall low-dose RT is a very effective treatment in painful heel spurs.

- Abstract
The impact of squamous cell carcinoma antigen (SCC) in the follow-up of patients with advanced cervical cancer treated with (chemo-) radiotherapy in primary and postoperative settings was evaluated. One hundred and forty-one patients with histologically proven squamous cell carcinoma of the uterine cervix were treated at the department of radiotherapy and radiation oncology. The serum level of SCC before treatment was elevated in 72% of the patients (cut-off level: 2.0 ng/ml). The course of SCC levels during (chemo-)radiotherapy reflects the tumor response: those patients, who had no significant decline of tumor marker values, had a lower response rate and worse outcome (p<0.001). Patients with a SCC level below the median of 7.2 U/ml had a significantly better prognosis and a better treatment response than those above the median (p=0.001). After treatment, 98% of patients with complete remission and 87% of patients with partial remission had a serum level below the cut-off In the case of recurrent disease, 82% of patients had a significant increase of SCC serum levels (p <0.001) before clinical manifestation of relapse. The lead- time ranged between one and 16 months (median: 4.5 months). We concluded that SCC is an essential tumor marker for monitoring treatment response and detecting recurrences in patients with squamous cell carcinoma of the uterine cervix undergoing (chemo-) radiotherapy. In this retrospective analysis, the value of SCC correlated with prognosis in patients with carcinoma of the cervix treated with (chemo-)radiotherapy.

- Abstract
Background: The aim of this study was to investigate, whether ultrasensitive PSA assays can help to find a lower cut-off value for biochemical recurrence of prostate cancer after resection., Materials and Methods: This was a retrospective analysis of the patient files of 113 men with prostate cancer who underwent surgery. The mean follow-up time was 26 months. PSA measurements were performed with the ultra sensitive Immulite assay (DPC, USA), with an analytical sensitivity of 0.001 ng PSA/ml. Patients with baseline PSA levels > 0.1 ng/ml after surgery were excluded. Different cut-off levels for PSA were applied on the values and PSA doubling-times calculated., Results: Maximum PSA 0.01 ng/ml, 0.05 ng/ml, 0.1 ng/ml, 0.2 ng/ml and > 0.4 ng/ml were reached by 87%, 61%, 50%, 42% and 20% of patients, respectively. From a cut-off point of 0.1 ng/ml the chance of further progression to PSA levels of 0.2 ng/ml and 0.4 ng/ml was 75% and 40%, respectively. The PSA doubling time was 2.1 months in patients with PSA values > 0.4, 15 months for patients below 0.4 ng/ml and 22.4 months for patients whose PSA never exceeded 0.1 ng/ml., Conclusion: PSA cut-off values below 0.4 ng/ml lack sufficient clinical significance. However, patients with PSA values > 0.1 ng/ml should be monitored thoroughly and at shorter intervals, as further increase, i.e. tumour progression, is very likely to occur.

- Abstract
Malignant salivary gland tumours are rare. The most common tumour site is the parotid. Aetiologic factors are not clear. Nutrition may be a risk factor, as well as irradiation or an histologically benign tumour occurred at a young age. Painless swelling of a salivary gland should always be considered as suspicious, especially if no sign of inflammation is present. Signs and symptoms related to major salivary gland tumours differ from those concerning minor salivary gland tumours, as they depend on the different location of the salivary gland. Surgical excision represents the standard option in the treatment of resectable tumours of both major and minor salivary glands. Neutron radiation may be a treatment option for inoperable locoregional disease. Surgery, irradiation or re-irradiation are treatment options for local relapse, whereas radical neck dissection is indicated for regional relapses. Metastastic disease may be either treated with radiotherapy or palliative chemotherapy, depending on the site of metastases.

- Abstract
Purpose: The aim of this investigation was to describe the alterations in oral mucosa after radiotherapy., Methods and Materials: Biopsies were taken from patients before irradiation, at 60 Gy, and 6-12 months after radiotherapy. Histomorphological evaluation of the vessels was performed, and endothelial expression of ICAM-1, VCAM-1, and E-selectin was also evaluated, as well as distribution of LFA-1-, Mac-1-, VLA-4-, RM3/1-, 27E10-, and 25F9-bearing cells in the subepithelial tissue., Results: The expression of ICAM-1 was downregulated after radiotherapy, whereas the percentage of LFA-1- and VLA-4-bearing cells increased. VCAM-1 remained at low levels. The subepithelial infiltration was still dominated by RM3/1-positive macrophages. The number of vessels decreased, while the lumina of the remaining vessels in the deeper connective layer increased., Conclusions: The late effects of radiotherapy are characterized by a decreased number of blood vessels and by significantly different expression patterns of the adhesion molecules studied, and of integrins and macrophage subpopulations compared to the conditions before irradiation and at 60 Gy.
