Purpose: Oral cancer resection can cause physical and psychological impairments that influence the quality of life (QoL). Depending on the postoperative time-distance, the occurrence and intensity of these impairments may change. We evaluated the sequelae and changes in therapy-related impairments during the postoperative course to detect associations between the time since surgery and the presence of disorders., Methods: Data from a questionnaire completed by 1359 patients who underwent surgical treatment of oral squamous cell carcinoma and were involved in a multicenter rehabilitation study of the German-Austrian-Swiss Cooperative Group on Tumors of the Maxillofacial Region (DÖSAK) that included 43 oral and maxillofacial clinics in Germany, Austria, and Switzerland were retrospectively analyzed., Results: Physical impairments, including those in appearance, mouth opening ability, ability to smell, gastric disorders, mandible mobility, breathing, and shoulder/arm mobility, were significantly associated with and increased with time-distance since surgery. Esthetic appearance most strongly correlated with the highest perception of worsening. Regarding psychological disorders, worry about tumor recurrence, depression, and worse prospects were significantly associated. Among the postoperative sequelae, fear of tumor recurrence decreased continuously; however, depression and worse prospects increased. The general QoL did not significantly differ overall during the postoperative course., Conclusions: Therapy-related impairments change during the postoperative course based on the time-distance since surgery. The general QoL may not markedly vary; however, single impairments, to some extent, can increase or decrease., Implications for Cancer Survivors: Continuous adaptation of supportive cancer therapy is required during follow-up to sufficiently address individual treatment needs., (© 2021.

Objectives: After resection of an oral carcinoma, patients are faced with physical, psychological, and socioeconomic challenges. Rehabilitation plays an essential role in patients' reintegration into their social and professional environment. This study evaluated whether socioeconomic aspects affect oral cancer patients' participation in rehabilitation treatment., Materials and Methods: A retrospective analysis was conducted with 1,532 patients following surgical treatment of oral cancer during an international multicenter rehabilitation study of the German-Swiss-Austrian Cooperative Working Group on Maxillofacial Tumors using a questionnaire comprising disease-related and psychosocial items postoperatively and at least 6 months after surgery., Results: Only 35.4% of patients participated in rehabilitation. Age (p<0.001), sex (p<0.001), and marital status (p<0.05) significantly influenced participation in rehabilitation. Postoperative impairment (p<0.05) as well as quality of life (p<0.01) were significantly worse in patients who participated in rehabilitation. Nevertheless, this group of patients returned to work significantly more often, although later, than those who did not participate in rehabilitation (p<0.05)., Conclusions: The findings show social inequalities and suggest a general undersupply of rehabilitative follow-up treatment in patients with oral cancer. More patients, especially older people and women should be referred to rehabilitation., Competing Interests: The authors declare that they have no competing interests., (Copyright © 2022 Korn et al.)

Purpose: Patients with oral cancer have gender-specific differences with respect to health-related quality of life (HRQoL) and psychosocial variables (PV). The aim of the present study was to evaluate HRQoL and PV outcomes in patients treated for oral squamous cell carcinoma., Methods: Data of 1234 patients were collected from a multicenter rehabilitation study of the German-Austrian-Swiss Cooperative Group on Tumours of the Maxillofacial Region (DÖSAK). Patient characteristics, oncological variables, post-treatment impairments, general quality of life (QoL), and PV (coping strategies, control beliefs, personal traits, perceived social support, depression, anxiety, and fear of tumor recurrence) were recorded., Results: After treatment, HRQoL was similar between genders concerning general QoL, but men experienced significantly more treatment-related functional impairments influencing HRQoL. PV revealed gender-specific coping strategies, with women reporting significantly more "depressive coping," "religiosity," "fatalistic externality," and higher "social burden." Owing to their religious coping strategies, fatalistic attitude, and perceived higher social integration, women demonstrated superior disease acceptance, despite higher depression, anxiety, and lower psychosocial resilience. Conversely, men reported more introverted personal traits and lower social integration., Conclusion: Interventions during oral cancer treatment should address PV and have gender-specific elements to improve HRQoL after therapy., (© 2022.

Purpose: Surgical therapy for oral cancer can lead to severe physical and psychological disorders that negatively impact patient quality of life (QoL). This study aimed to evaluate the relationship between fulfillment of patients' information needs during oral cancer treatment and patients' perception of posttherapeutic disorders influencing QoL., Methods: A retrospective analysis of 1359 patients who were surgically treated for oral cancer using questionnaires administered during the multicenter rehabilitation study by the German-Austrian-Swiss Cooperative Group on Tumors of the Maxillofacial Region (DÖSAK). Patients and medical practitioners completed questionnaires following cancer treatment., Results: Approximately 37% of patients felt inadequately informed about possible physical and psychological consequences of surgery. In contrast, only 16% of patients felt they were given inadequate information about the operative procedure and possible complications, and with regard to tumor diagnosis and cancer disease, only 15% of patients. Significant correlations were found between lacking information and increased perception of posttherapeutic disorders, whereas correlations with tumor-specific and operation-related parameters were markedly lower. The patients with superior QoL after treatment stated more frequently, nearly independent of individual patient characteristics, that the information that they were given prior to therapy was adequate. Information concerning possible physical and psychological consequences of an operation, however, was frequently stated to be inadequate, independent of QoL., Conclusion: Patients whose information needs concerning the diagnosis and treatment of oral cancer are adequately fulfilled may benefit in terms of their therapeutic outcome, experiencing less perception of posttherapeutic physical and psychological disorders and a superior QoL.

Background: Tumorous diseases of the head and neck region annually occur in more than 550.000 cases worldwide. Little is known about patient specific care needs and potential relationships between non-fulfillment of those following therapeutic and especially surgical treatment of head and neck cancer (HNC)., Objectives: This study aimed to evaluate potential correlations between patient specific care needs, regarding physiological rehabilitation, family/social support, economic needs, and their impact on health-related quality of life (HRQoL)., Methods: A total of 1359 patients were included in this retrospective analysis. Data derived from the exploratory international multicenter rehabilitation study of the German-Austrian-Swiss Cooperative Group on Tumors of the Maxillofacial Region (DÖSAK), including 43 oral and maxillofacial departments in Germany, Austria, and Switzerland using the Bochum patient questionnaire on rehabilitation and a questionnaire on tumor and treatment related data., Results: Results showed a significant correlation of a patient's social bonds and depression, coping with depression, and anxiety. Patients' needs for speech therapy, physiotherapy or respiratory training were hardly ever met and patients had to compensate for financial losses during hospitalization for acute treatment., Conclusion: In conclusion, this study describes social, physical, and socio-economic care needs. A multidisciplinary approach managing cancer and treatment related side effects is necessary, as well as enhanced awareness of care needs of practitioners during early recovery after surgery., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

Background: Posttherapeutic mucositis is a common secondary effect of oral cancer treatment. Mucositis affects the oral mucosa, which leads to specific physical impairments in oral function and a negative impact on quality of life., Objective: To evaluate the impairments associated with oral mucositis and their impact on posttherapeutic quality of life., Methods: A retrospective analysis was conducted on 1,652 patients treated for oral cancer during the multicenter rehabilitation study of the German-Austrian-Swiss Cooperative Group on Tumors of the Maxillofacial Region (DÖSAK), which included 43 clinics from Germany, Austria, and Switzerland. The analysis was based on questionnaires filled out by patients following treatment., Results: Approximately 10% of 1,652 patients included in our study had physical or psychological impairments due to increased posttreatment oral mucositis; this was mainly due to adjuvant radiotherapy or radiochemotherapy administered. Oral mucositis was significantly associated with specific physical impairments, especially xerostomia and pain (p = 0.000), which required supportive care and analgesia (p = 0.000). Additionally, impaired ingestion and speech significantly led to psychological disorders such as public avoidance behavior and social isolation (p = 0.001). Depressive coping of disease (p = 0.001) and concomitant depressive tendencies (p = 0.004) were highly associated with mucositis, which was accompanied by diminished general condition (p = 0.001), bleak future prospects (p = 0.006), and a reduction in quality of life (p = 0.002)., Conclusion: Minimizing mucositis-related impairments should be a main effort in oral cancer treatment to optimize patient outcome and improve quality of life after therapy., (© 2019 S.

Objectives: The aim of the current study was to evaluate the functional and psychosocial impacts and changes in overall quality of life (QoL) following oral squamous cell carcinoma (OSCC) therapy in different age groups and in different oral locations., Materials and Methods: The study assessed questionnaire responses from patients with OSCC (n = 1319) after 6 months of oncologic therapy, as collected in the DÖSAK Rehab Study. Oncological variables, dental status, sensory, QoL, psychosocial outcomes and coping strategies in younger (45-60 years) and older (61-100 years) patients were assessed for different OSCC locations including the entire oral cavity, maxilla, mandible and others besides the maxilla and mandible., Results: Younger patients were generally less satisfied with their dental status and experienced more sensory and QoL impairments, as well as more psychological burden, compared to the older patients. Depending on the age group, different coping strategies were used. Oncologic therapy targeted to the mandible and other locations besides the maxilla and mandible led to the strongest sensory and QoL limitations., Conclusions: Regardless of age, oncologic OSCC therapy leads to profound sensory and psychosocial restrictions and to limitations in QoL. Reasons for the poorer functional and QoL outcomes in younger patients include a more invasive treatment and a lower psychosocial resilience. The identification of patients with depressive and dysfunctional coping strategies should be carried out for all ages, but especially in younger patients, in order to develop functional coping strategies through individualized counseling, treatment and rehabilitation., Registration of Clinical Trials: Observational study, therefore not required., (Copyright © 2018 Elsevier Ltd.

Background: The impairment of the appearance is a major problem for patients with carcinomas of the oral cavity. These patients want to recover their preoperative facial appearance. Some do not realize that this is not always possible and hence develop a desire for further cosmetic and reconstructive surgery (CRS) which often causes psychological problems., Method: The desire of patients for CRS ( N  = 410; 26%) has been acquired in this DÖSAK rehab study including multiple reasons such as medical, functional, aesthetic and psychosocial aspects. They relate to the parameters of diagnosis, treatment and postoperative rehabilitation. Patients without the wish for CRS ( N  = 1155; 74%) served as control group. For the surgeons, knowledge of the patient's views is relevant in the wish for CRS. Nevertheless, it has hardly been investigated for patients postoperatively to complete resection of oral cancer. In this retrospective cross-sectional study, questionnaires with 147 variables were completed during control appointments. Thirty-eight departments of Oral and Maxillofacial Surgery took part, and 1652 German patients at least 6 months after complete cancer resection answered the questions. Additionally, a physician's questionnaire ( N  = 1489) was available. Statistical analysis was performed with SPSS vers. 22., Results: The patient's assessment of their appearance and scarring are the most important criteria resulting in wishes for CRS. Furthermore, functional limitations such as eating/swallowing, pain of the facial muscles, numb regions in the operating field, dealing with the social environment, return to work, tumour size and location, removal and reconstruction are closely related., Conclusion: The wish for CRS depends on diverse functional psychosocial and psychological parameters. Hence, it has to be issued during conversation to improve rehabilitation. A decision on the medical treatment can be of greater satisfaction if the surgeon knows the patients' needs and is able to compare them with the medical capabilities. The informed consent between doctor and patient in regard to these findings is necessary.

Purpose: In this study of patients with oral squamous cell carcinoma, the authors sought to clarify the functional and psychosocial harms of neck dissection (ND), which lessens quality of life., Materials and Methods: The study included questionnaire responses from patients with oral squamous cell carcinoma (n = 1,652) and clinicians (n = 1,489), as collected in the DÖSAK Rehab Study. Psychosocial and functional factors were assessed. Functional and psychosocial outcomes in patients who did not receive ND were compared with those in patients who underwent selective supraomohyoid ND (SND), modified radical ND (MND), and radical ND (RND)., Results: Patients with ND had lower quality of life than those without ND. Burdens after SND (n = 923) were generally lesser than those after MND (n = 301) or RDN (n = 678). There were meaningful differences between the SND, MND, and RND and without-ND groups in impairments in speech intelligibility for strangers and familiar persons, ingestion and swallowing, tongue mobility, opening of the mouth, lower jaw mobility, neck mobility, and shoulder and arm movement (P < .05). Many patients with ND faced a lower functional status and negative professional and financial consequences., Conclusions: Because of the burdens associated with ND, the decision to perform this treatment for oral squamous cell carcinoma should incorporate information on health-related quality of life and survival rates., (Copyright © 2016 American Association of Oral and Maxillofacial Surgeons.

Background: The incidence of oral squamous cell carcinoma (OSCC) is in the top 10 of all cancer entities. Regular oral examinations by dentists play an important role in oral cancer prevention., Methods: Patients with OSCC ( n = 1,607) and physicians ( n = 1,489) completed questionnaires during the DÖSAK Rehab Study. The psychosocial and functional factors collected in these questionnaires were assessed in the present study. We compared patients who visited their dentist at least once a year (group A) with those who visited their dentist less than once a year (group B)., Results: Patients in group A had significantly better health-related quality of life after tumor treatment than patients in group B. Patients in group A also had a smaller tumor size and less lymph node metastasis and lost fewer teeth during the treatment. This resulted in better prosthetic rehabilitation and better psychological status after tumor treatment., Conclusions: Dentists play an important role in the early recognition of oral cancer. This study should encourage dentists to take a more active role in oral cancer prevention.

Diet is important for both quality of life (QoL) and survival of patients with oral cancer. Their intake of food is impeded by functional restrictions in chewing and swallowing. In the DÖSAK REHAB STUDY 1652 patients from 38 hospitals within the German-language area of Germany; Austria and Switzerland were examined with regard to functional and psychological variables having an impact on diet. Chewing and swallowing are correlated with mobility of the tongue and the mandible as well as opening of the mouth. Thirty five percent of the patients lost weight; 41% maintained their weight and 24% gained weight. The QoL of patients who were able to maintain their weight and of those who gained weight was significantly better than that of patients who lost weight. A normal diet was important for maintaining weight. Mashed food; liquid food and loss of appetite were closely associated with loss of weight; although it was possible for nutritional counseling and dietary support to be implemented particularly favorably in this respect. Due to problems with eating patients' strength deteriorated; thus restricting activity. Radiotherapy had a negative impact on diet and weight. It influenced sense of taste; dryness of the mouth; swelling and discomfort when ingesting food. Pain and scars in the region of the operation also cause patients to dislike hard; spicy and sour food. Support from a nutritional counselor in implementing a calorie-rich diet remedied this and such support needs to be integrated into patient management. The fact that a poor nutritional status is of such great importance is well-known; but what is often lacking is the systematic implementation of continued professional nutritional counseling over a long period of time; weight control and psycho-social support of the operated patients; particularly those who also have had radiotherapy.

Background: Return to work (REW) after cancer treatment is important for both patients and their families and for society in general. For patients it can be a sign of complete recovery and return to normal life., Patients and Methods: A total of 755 out of 1,652 patients from 38 hospitals within the German-language area (DÖSAK REHA STUDY) were working at the time their cancer was diagnosed. QoL was determined after therapy and ranges from 0 to 100%., Results: Overall, 51% were blue-collar workers (BCWs) and 49% white-collar workers (WCWs). The WCWs resumed work significantly sooner. There were no differences in the medical parameters. For 19 impairments, there were considerably more severe impairments reported in the self-administered questionnaires for BCWs. The groups did not differ with regard to depressive moods. Patient behaviour changed in several dimensions as a result of the treatment., Conclusion: WCWs managed to return more frequently and faster to work than BCWs. It is important that the rehabilitative measures be coordinated.

Unlabelled: Quality of life (QoL) in head and neck cancer patients has been of increasing interest for some years. Unfortunately, only poor data exist regarding the impact of professional psychological support on QoL., Objectives: The purpose of this study was to investigate psychological aspects of QoL as well as the potential need for additional psychological treatment., Material and Methods: A total collective of 1761 patients from 38 hospitals yielding 1652 patients' questionnaires containing 147 items was evaluated. QoL, impairments and psychological and surgical treatment were evaluated., Results: Most patients had no psychological interview, and the majority of those who had an interview did not even want one. However, 17% of those patients who did not receive an interview wished to have one. When a psychological interview was performed, most patients (77.5%) evaluated this as helpful. Patients who wished to have a psychological interview but did not receive one showed a significantly worse QoL than those patients without a wish for such an interview. Moreover, having an interview, which does not meet the needs of the patients, diminishes QoL compared with not having an interview., Conclusions: Taken together, these findings emphasise the impact of psychological treatment at least on a significant number of head and neck cancer patients., (Copyright © 2012 John Wiley & Sons, Ltd.)

Objectives: Besides survival time quality of life (QoL) is the most important criterion for measuring the success of the therapy and rehabilitation of patients with carcinoma of the oral cavity. Interestingly, assessments by doctors sometimes differ from those of patients concerning QoL and level of information. Particularly the probability of cancer recurrence is unclear for many patients., Material and Methods: Fear of recurrence (FOR) data were gathered from a total collective of 1761 patients from 38 hospitals within the German-language area of Germany, Austria and Switzerland (DÖSAK-REHAB-STUDIE) yielding 1652 patient questionnaires containing 147 items which were evaluated. They refer to periods at least 6 months after therapy. QoL was determined by the patient and ranges from 0% to 100% and FOR was measured using a Likert scale. Statistical analysis was performed using SPSS 19.0., Results: FOR affected 80% of the patients to a varying degree and influenced QoL very significantly. Patients with a high level of FOR were also more mentally instable. Their functional impairment in particular contributed to a reduced QoL. They felt less informed by their doctors about their illness and rehabilitation. The medical parameters had a smaller influence on FOR and QoL., Conclusion: The patients' knowledge of their medical situation must be improved to make patient assessment of QoL more realistic, particularly when patients with good prospects indicate low QoL. The patients' subjective evaluations have to be more strongly integrated into the concept of the multi-disciplinary team in establishing a comprehensive therapy and rehabilitation plan., (Copyright © 2012 Elsevier Ltd.

Smoking is a causative factor in oral squamous cell carcinomas (SCC). Unfortunately, only poor data exist regarding the quality of life of smokers vs non-smokers with SCC. The purpose of this study is to show a correlation between variables for comprehensive interdisciplinary rehabilitation and better patient quality of life (LQ). A total collective of 1,761 patients from 38 hospitals within the German-language area of Germany, Austria and Switzerland (DÖSAK-REHAB-STUDIE) yielding 1,652 patients' questionnaires containing 147 items were evaluated. They refer to the periods before (t1) and immediately after surgery (t2), as well as at least 6 months later (t3). LQ was determined by the patient and ranges from 0% to 100%. Significant differences were found between smokers (80%) and non-smokers (20%) with respect to diagnosis, therapy and rehabilitation. Disabilities and impairments in speech, appearance, chewing/swallowing, pain and LQ were examined. Smokers were more often and more severely affected. Differences were found in the size of the tumour, scar tissue, ingestion, functionality of the facial muscles and a numb feeling in the head and shoulder area. Smoking has a severe effect on the oral cavity. Non-smokers suffer far less from the effects of SCC and the ensuing therapy. During therapy and rehabilitation, the LQ is much higher in non-smokers. This supports the importance of enhanced efforts to inform people about the consequences of smoking so as to prevent them from smoking. Moreover, psychological support might be helpful to give up smoking.

Purpose: The therapy of patients with oral cancer often requires a combination of surgery and radiotherapy. This leads to trauma of healthy tissue. The impact of this side effect on quality of life was investigated. Additionally the impairment of 19 factors was determined (comprehension of speech for unknown others, comprehension of speech for familiar others, eating/swallowing, mobility of the tongue, opening range of the mouth, mobility of lower jaw, mobility of neck, mobility of arms and shoulders, sense of taste, sense of smell, appearance, strength, appetite, respiration, pain, swelling, xerostomia, halitosis)., Methods: This retrospective multicenter study was conducted under the auspices of DOESAK (a German, Austrian and Swiss cooperative group on tumors of the maxillofacial region). The Bochum Questionnaire on Rehabilitation was used to determine 147 items. 3894 questionnaires where sent to 43 clinics in Germany, Austria and Switzerland. 1761 questionnaires where returned, while 1411 of them included all of the answers necessary for this study., Results: 686 of 1411 patients where irradiated. Before the beginning of therapy the impairment of the 19 factors was not significantly higher in the group that later received radiotherapy. After therapy there is a significantly higher impairment of the irradiated patients. The factors that are especially worse are xerostomia, swallowing and understanding of speech. The quality of life was not significantly lower., Conclusions: Although radiotherapy leads to trauma of healthy tissue this method is indicated as it has no significant impact on quality of life. During the rehabilitation physiotherapists should relieve the impairment of speech, eating and swallowing.

Purpose: The surgical treatment of oral cancer results in functional and aesthetical impairments. Patients' quality of life is considerably impaired by oral symptoms resulting from therapy of oral cancer. In many cases the inevitable resection of the tumor, as well as the adjuvant radiochemotherapy will cause the destruction of physiologically and anatomically important structures. One focus of research was the specific rehabilitation of dental loss by functional dentures. Another was the course of 19 impairments (comprehension of speech for unknown others, comprehension of speech for familiar others, eating/swallowing, mobility of the tongue, opening range of the mouth, mobility of lower jaw, mobility of neck, mobility of arms and shoulders, sense of taste, sense of smell, appearance, strength, appetite, respiration, pain, swelling, xerostomia, halitosis)., Methods: Commissioned by the German, Austrian and Swiss cooperative group on tumors of the maxillofacial region (DOSAK), data were collected in 3.894 questionnaires at 43 hospitals in Germany, Austria and Switzerland. The catalogue comprised 147 items in 9 chapters. At the end of the enquiry, 1.761 anonymous questionnaires were returned by 38 hospitals. 1.652 of these could be evaluated regarding the question., Results: The sum score of the 19 impairments was highly increased immediately after the operation and recovered over the next 6 months, without, however, reaching the pre-surgery level. Of 1.652 patients, only 35% did not lose any teeth during therapy. 23% lost up to 5, 17% up to 10 teeth. A quarter of the patients lost more than 10 teeth. The more teeth were lost, the greater the decline of quality of life (p < or = 0.001), although this could be allayed by the functionality of the dentures (p < or = 0.001). There is a reciprocal dependence between the functionality of dental prosthetics and impairment by eating/swallowing (p < or = 0.001)., Conclusions: Patients' quality of life after radical surgery of a carcinoma of the oral cavity depends not only on the functionality of dentures and the specificity of rehabilitation, but also from the initial findings, the extent and location of the resection, the chosen therapy, the general circumstances of the patient's life as well as their strategies of coping. These factors, however, unlike those of functionality of dental prosthesis and rehabilitation, are not modifiable.
