Qualitative research is very common and valued in international medical journals and scientific research.
In order to increase the quality and clarity of scientific research, it is important to: establish the main objective and specific objectives of the study, consider the research question ( research problem), establish research hypotheses, use appropriate research methods and present relevant conclusions, as well as the completeness and clarity of research reporting.
The quality of life of patients affected by oncological diseases is one of the strategic areas of research in medicine and health psychology. The progression of the disease, its treatment and possible complications affect both physical aspects and the emotional and social functioning of the patient [8,9].
Therefore, the evaluation of prognostic factors affecting quality of life is very important in patients with head cancer after surgical treatment. In addition to the physical aspects, the psychological well-being of cancer patients is extremely important. The diagnosis and long-term treatment often lead to severe stress, sleep difficulties and lowered mood, which can develop into more serious disorders such as depression or anxiety. Patients also struggle with uncertainty about the future, which puts additional strain on their mental health. Cancer patients' quality of life also includes the social sphere, which plays a key role in the treatment process and adaptation to a new reality. Relationships with loved ones, the possibility to receive emotional support and the maintenance of existing social roles can affect the level of satisfaction with life despite the disease. The support of the environment, both from family and professional caregivers, helps patients cope with daily challenges and better adapt to changing conditions. The spiritual dimension cannot be overlooked either, and for many patients this becomes an extremely important part of coping with their illness. Finding meaning in a difficult situation, accepting a new reality and developing ways to maintain internal balance can contribute to an improvement in overall well-being [12–14].
The success of cancer therapy is not just about prolonging a patient's life, but also about maintaining it to the highest possible quality. Cancer treatment is accompanied by numerous side effects that can significantly reduce the patient's quality of life. Analysis of these aspects allows us to better understand the needs of patients and to tailor medical and psychological care in a way that improves their quality of life despite the difficulties resulting from the disease and its treatment. Research on quality of life not only assesses the effectiveness of treatment, but also allows the therapeutic approach to be adapted in a way that takes into account medical outcomes, comfort and well-being of patients [15].
The negative effects of head cancer have been attributed to both the natural progression of the disease and treatment, which usually consists of maximally safe chirurgical resection followed at some point by radiation therapy, chemotherapy or a combination of the two.
Concerns about tumor recurrence/progression, limited ability to work and reduced functional independence can add to patients' suffering [4].
Awareness of the importance of exercise therapy and neurological rehabilitation to prevent complications after surgery for head cancer during and after treatment is growing rapidly. Sufficient levels of physical activity before, during and after cancer treatment have been shown to be associated with a better prognosis, lower risk of recurrence and mortality, and fewer negative treatment-related side effects [7].
The European Organization for Research, Treatment of Cancer (EORTC) introduced the Quality of Life Assessment Tool in 1994 as a way to measure quality of life in cancer. This was useful in identifying patients whose lower quality of life had a major impact on their daily living activities, particularly to the greatest extent after surgical treatment.
Describing the needs of head and neck cancer patients during follow-up care is a critical step in evaluating current practice and designing for improvement.
Future research efforts should include collaborating with other researchers to select standardized instruments to improve comparability between studies, and gathering rich information from patients through experiences detailed in qualitative studies. Evaluating other creative approaches to meeting the needs of this patient population through randomized controlled trials and raising awareness among health care providers about unmet patient needs and prognostic factors affecting patients' quality of life.
This study highlights the importance of identifying each patient's individual and unique needs as part of routine follow-up care. Future studies are needed to elucidate the reasons for unmet care, assess the psychological support of patients diagnosed with head cancer to help improve the quality of life of these patients, and the need to analyze prognostic factors affect quality of life [16].
Addition, analysis of quality of life survey results can help identify subgroups of patients who are more likely to experience disorders and therefore require additional targeted support in their recovery [17].
The difficulty is how best to define the concepts of quality of life and how to measure them empirically and then draw conclusions that will serve to improve the quality of life of cancer patients [18].
Thanks to medical advances over the past 20 years, the marked increase in the life expectancy of patients with diffuse glioma opens the field to new therapeutic targets.
Neurocognitive performance, epileptic seizures and activities of daily living are direct indicators of brain function and quality of life in patients with diffuse glioma.
The number of tumor resections is positively correlated with return to normal socio-professional life. Rydén and co-authors add that age, cognitive function, resection and follow-up treatment (chemotherapy or radiation therapy) determine return to work [2].
The results of the study by Vigano et al. showed that after a longer period of time after surgery and radiotherapy, quality of life improved after 3–6 months compared to immediately after surgery. Time was found to be a predictor of all three factors of the questionnaire, that is, general and specific symptoms and interference with daily life [19].
Our own research has shown that the prognostic factors affecting the quality of life of patients three months after surgery for head cancer include the type of cancer, patients' independence, acceptance of the disease and social support. The level of quality of life as exemplified by the somatic, psychological, social and environmental domains in the study group of patients three months after surgery for head cancer can be described as good, taking into account the cause of the cancerous lesion.
Quality of life is becoming an important issue in clinical decision-making for gliomas.
Some patients returned to an active socio-occupational life after surgery for glioma after repeat surgery, and some patients showed neurocognitive impairment in the post-operative period, which significantly affected their quality of life.
Several studies have found that lower physical fitness in glioma patients is associated with higher levels of fatigue and more impairment, so exercise and other interventions to improve physical functioning could potentially help reduce symptoms and improve quality of life [4].
Our own study showed that in terms of somatic and psychological domains, the lowest quality of life three months after surgery for head cancer was reported in the group of patients with glioma, and the highest in the group of patients with meningioma.
Since cancer patients often begin treatment with poor physical fitness, exercise therapy should be started at the time of diagnosis and continued during and after treatment.
The results of the study by Vigano et al. showed that older patients had a reduced quality of life, which is understandable in that patients who have undergone surgery for head cancer may be debilitated, have poorer physical function even before surgery, and are additionally burdened by multiple chronic diseases [19].
Hannon et al. showed a correlation between poor quality of life and reduced satisfaction with treatment and acceptance of the disease. In addition, patients who were less satisfied with their treatment had a reduced quality of life [20].
Our own research similarly showed that the more independent the patients were three months after surgery for head cancer, the higher their quality of life and the better they accepted their illness, and the less social support they needed.
The long-term neurocognitive and psychosocial sequelae of treatment are increasingly important in patients with head cancer. Prospective evaluations of the efficacy of cancer-targeted treatment appear to be crucial [21].
Treatment in patients with head cancer often interferes with vital structures, resulting in survivors experiencing bio-psycho-social problems related to changes in appearance, communication, breathing, eating and drinking, intimate relationships, and feeling their impact on long-term quality of life [22].
A strength of the present study is the use of four research tools that are standarised, which translated into the reliability of the results. In addition, the study was conducted in a thorough and reliable manner and lasted a long period of time − 16 months. Also a strength is the innovative nature of the study and the emphasis on its direct relevance to the care of oncology patients with head cancer.
A weakness of the study was the relatively small size of the study group, due to the fact that some patients refused to participate in the study due to health difficulties and could not complete the questionnaires.
In the light of the results obtained and taking into account the limitations of the study, it seems reasonable to continue research into the quality of life of oncology patients on a larger scale. In the future, it would be worth considering conducting studies on larger and more diverse patient populations, which would increase the statistical power of the analyses and enable a more precise assessment of the impact of individual clinical and socio-demographic factors on quality of life.
