Background: The purpose of this study is to examine the effect of psychological intervention on the life quality of patients with laryngeal cancer.
Methods: Two hundred and ten patients with laryngeal cancer were randomly assigned to the study group receiving psychological intervention and control group receiving routine nursing care. The Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), and the Europe Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) were used to evaluate life quality.
Results: There were no significant differences in the scores of HAMD, HAMA, and EORTC QLQ-C30 between the 2 groups before treatment (P>0.05). After treatment, the scores in the study group were significantly different to those in the control group (P<0.05). In addition, the satisfaction rate and compliance rate of patients in the study group were increased, compared to the control group (P<0.05).
Conclusion: Psychological intervention is beneficial in improving life quality in patients with laryngeal cancer after surgery.

Keywords: psychological intervention, compliance, laryngeal cancer

Introduction

Laryngeal cancer is one of the most frequently diagnosed malignancies in head and neck, accounting for 5.7%–7.6% of all cancer cases.1 Environmental pollution, especially in some developing countries, is an important contributor to the increasing incidence of laryngeal cancer.2 Common symptoms include hoarseness, dysphagia, trouble breathing, and lump in the neck.3 Surgery is currently the main treatment for laryngeal cancer.4 The 5-year survival rate for patients with laryngeal cancer at stages I and II is >68% after surgical resection, while at stages III and IV the survival rate is only 40%–50%. Laryngectomy, either partial or total, is associated with a high incidence of postoperative complications, thus reducing life quality and leading to poor compliance.57

In the present study, we implemented psychological intervention nursing in patients with laryngeal cancer during hospitalization. The Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Europe Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), satisfaction rate, and adherence rate were used to assess the effect of psychological intervention.

Patients and methods

Patients

We enrolled 210 patients with laryngeal cancer who were admitted to the Department of Otolaryngology-Head and Neck Surgery of The Second Affiliated Hospital of Xi’an Jiaotong University (Xi’an, People’s Republic of China) from March 2014 to August 2016. Written informed consent for research was obtained from each patient, and this study was approved by the Institutional Human Experiment and Ethics Committee of The Second Affiliated Hospital of Xi’an Jiaotong University. Inclusion criteria were pathological diagnosis of laryngeal cancer, eligibility to receive psychological intervention, and normal psychological behaviors. The patients were randomly assigned to 2 groups: control group (n=108) and intervention group (n=102). In the control group, there were 62 males and 46 females, with a mean age of 55.25±2.38 years (range, 39–76 years). In the intervention group, 59 were men and 43 were women, with a mean age of 55.27±2.40 years (range, 40–76 years). Concerning their education, 42 and 38 patients graduated from high school and 47 and 44 patients had a bachelor’s degree in the control and intervention groups, respectively. No significant difference in the parameters studied was noted between the 2 groups. Patients in the intervention group were given psychological intervention, while those in the control group were given a standard nursing care (Figure 1).

Psychological intervention

We developed a series of patient intervention programs. The detailed protocols are summarized in this paper. Before surgery, clinicians explained advanced surgical instruments and procedures to patients and encouraged them to receive the therapy. Also, patients were informed of the potential surgery-related risks and complications. Preoperative psychological intervention aimed to reduce anxiety levels of patients.8 Moreover, description of successful surgical cases will enhance the confidence of the patients. Patients were warmly welcomed to the operating room. Nurses should provide a continuity of care throughout the perioperative period and explain to the patients what will happen during operation, attempting to alleviate any anxieties from surgery. After operation, the majority of patients find it difficult to accept the fact that they have lost the ability to speak. Therefore, it is important for nurses to provide delicate care and encourage them to face reality. In addition, patients need to be taught how to clean and sterilize the inner cannula, which would help them to increase self-care capacity.

Control group

The control group received routine nursing care, including introduction to the equipment and the environment. Patients were instructed to communicate through body language, pay attention to clean the oral cavity, and stop drinking and smoking. Meanwhile, nurses informed them regarding the operation necessity and attention after operation.

Observations

HAMA, HAMD, and EORTC QLQ-C30 assessment was performed by 8 nurses at 1 week before and 3 months after surgery. Mean durations and costs of hospitalization were recorded. Degree of satisfaction of patients was scored using Likert scales, ranging 1–5 (1= very unsatisfactory; 2= unsatisfactory; 3= moderate; 4= satisfactory; 5= very satisfactory). The questionnaire consisted of 10 single choice questions and 10 multiple choice questions. The scoring ranged from 1 to 5 points per question (1= much worse; 2= worse; 3= good; 4= better; 5= much better). The maximum score was 100.

Statistical analysis

Data analysis was performed using SPSS software (version 17.0; SPSS Inc., Chicago, IL, USA). A Student’s t-test and chi-square test were used to compare HAMA, HAMD, and EORTC QLQ-C30 between the 2 groups before and after treatment. Statistical significance was set at P<0.05.

Results

HAMD and HAMA scores

The HAMD and HAMA scores were significantly reduced in both the groups after treatment (P<0.05 vs. control values before treatment; Table 1). Moreover, compared to the control group, the intervention group had significantly lower HAMD and HAMA scores (P<0.05), suggesting a reduction of anxiety levels.

Assessment of survival quality

In terms of physical health, mental health, social function, self-evaluation, and special adverse reaction, patients in the intervention group had a significant improvement after treatment (P<0.05 vs the scores before treatment; Table 2). By contrast, patients in the control group had only an improvement of physical health after treatment.

Hospitalization duration and expenses, and patient satisfaction

With regard to hospitalization duration and expenses, there were significant differences between the 2 groups (P<0.05; Table 3). In addition, the 2 groups differed significantly in the satisfaction rate and compliance rate (P<0.05; Table 3).

Discussion

Quality of life is a multi-dimensional concept and quantitative measure that reflects physical activity and psychological status, which are associated with happiness, satisfaction, or gratification.9

With the change of modern medical model from biomedical model to biopsychosocial medical model, psychology has been widely used in clinic.10 Traditional medical therapies focus on the resolution of physical symptoms and prolongation of life span, but spare psychological disorders. Therefore, the purpose of improving the quality of treatment should include improvement of the quality of life of patients, restoration of the patient’s physical function, and maintenance of healthy psychological state of patients and social function.

Cancer-related emotional disorder has a deleterious impact on quality of life and patient compliance, consequently reducing overall survival by 10%–20%.11,12 After surgery, patients experience a painful process, such as pain, dry mouth, sticky saliva, feeling ill, and use of painkillers. They can easily suffer from depression and anxiety and commit suicide. Psychological intervention can preserve the confidence of patients, improve quality of life, and reduce cancer-specific anxiety and stress. For patients with laryngeal cancer, psychological intervention is particularly necessary because of the dramatic physical changes after surgery, such as loss of phonation, hyposmia, hypogeusia, and frequent coughing.13,14 This study was conducted to explore the clinical significance of psychological intervention in patients with laryngeal cancer. We found that HAMA and HAMD scores were significantly reduced in the intervention group, compared to the control group. Moreover, the life quality of patients in the intervention group improved after treatment. These data suggest that psychological intervention can alleviate anxiety levels and thus provide survival benefits to cancer patients.

Our data also showed that hospitalization duration and expense reduced and patient satisfaction increased in the intervention group, compared to the control group. These results suggest that psychological intervention contributes to the recovery of wounds after surgery. The reduction in therapy expense may enhance patient compliance. Increasing evidence indicates the importance of psychological intervention in the treatment of cancer patients. However, psychological intervention of cancer patients has not been widely employed in local hospitals in the People’s Republic of China.

With the rapid development of medical psychology in recent years, psychological intervention for improving the negative emotion of cancer patients, therapeutic effect, patient compliance, and quality of life of patients has attracted the attention of the whole society; some studies have proved that psychological intervention has become an integral part of the overall treatment of tumor.15 Although psychological intervention plays an important role in the treatment of tumors, the psychological intervention has not been widely used in the People’s Republic of China, especially in primary hospitals, even without a psychotherapist.16 The results of this study found that psychological intervention could improve anxiety, depression, and quality of life of patients. Therefore, in addition to the necessary surgery and drug treatment, psychological intervention is worthy of popularization and application.

Conclusion

Our data support that psychological intervention can improve the life quality of patients with laryngeal cancer. The psychological intervention should not be underestimated in clinical research.
