Quality of life during early radiotherapy in patients with head and neck cancer and pain

Dentists Role in Psychological Screening and Management of Head-and-neck Cancer Patients Undergoing Radiotherapy - Narrative Review

Objectives

Head-and-neck cancer management primarily involves surgery and chemoradiotherapy. Recurrent radiotherapy (RT) sessions are often linked to social, physical, and psychological burdens. Oral physicians are part of the palliative care team and play a pivotal role in decimating the physical side effects associated with disease and its treatment. There is a need to familiarise dentists with the psychological aspect of the treatment.

Material and Methods

Various libraries were searched from the year 2012 to 2022. A total of nine studies that had head-and-neck RT patients exclusively were included in the study.

Results

Anxiety and depression are patients' most prevalent psychological problems during and after the RT regimen. A few most used psychological screening tools were identified.

Conclusion

Dental professionals are uneducated about the holistic approach to managing RT patients. The current narrative review details the various psychological screening tools and care measures that can be incorporated into the dental setup to help these patients.

The impact of radiotherapy on the quality of life in patients with early-stage clinical head and neck cancer

Radiotherapy (RT) for patients with head and neck squamous cell carcinoma (HNSCC) affects vital functions related to the irradiation volume of the head and neck region and, in addition, has a negative impact on social functioning, thereby significantly impairing patients' quality of life (QoL). The aim of this study was to assess changes in the quality of life in patients with head and neck cancer treated with curative RT at 12 months after completion of RT. The aim of this study was to assess the differences between the baseline QoL of patients with early clinical stage HNSCC and at 12 months after curative/radical RT. The prospective clinical study included 92 patients in good general condition (ECOG 0-1 - Eastern Cooperative Oncology Group performance status), without regional or distant metastases, diagnosed with pathomorphologically confirmed early-stage head and neck squamous cell carcinoma treated with definitive RT. All patients participating in the study signed an informed consent form. QoL was assessed using the standard EORTC QLQ-C30 and QLQH&N35 questionnaires. In addition, information on clinical aspects and data relating to socio-demographic factors were obtained from each patient. Statistical analysis was performed using a statistical package (SPSS 17.0). T-test was used for dependent and independent samples. A general linear model was used for repeated measures. Patients' QoL deteriorated significantly after definitive RT. Worse QoL Core-30 scores in patients 12 months after the end of RT, compared with baseline QoL, before the start of RT, were observed in domains such as physical performance, fulfillment of life roles, cognitive functioning, loss of appetite, fatigue and constipation. For the QLQ-H&N35 questionnaires, patients 12 months after the end of RT reported problems in relation to aspects of life such as senses, mouth opening, dry mouth, thick saliva, pain, and weight loss. RT, even in early clinical stage head and neck cancer, has a negative impact on QoL, despite modern treatment techniques.

Pain management in patients undergoing radiation therapy for head and neck cancer - a descriptive study

OBJECTIVES

Patients with head and neck cancer (HNC) experience serious pain related to tumour, surgery, chemotherapy, and radiotherapy treatment (RT). Oral mucositis, a painful complication of RT, may require opioid analgesics to control pain.This longitudinal study, during RT but also four weeks post-RT, examines the relationships between oral mucositis, pain, and opioid doses in in HNC patients. The aim was to evaluate the clinical effectiveness of an opioid treatment strategy.

METHODS

Sixty-three patients with HNC undergoing radiotherapy answered self-reported questionnaires on pain intensity on a 0-10 numerical rating scale (NRS) three times a week. Oral mucositis signs were evaluated using the WHO mucositis index score, ranging from 0 (normal) to 4 (severe), and pharmacological treatment with opioids was registered prospectively once a week. All data were related to given radiation dose, and all outcome measures at each time point therefore relate to the same radiation dose (i.e., not to when the patient was included in the study).

RESULTS

Opioids were used by 78% of the patients. Most of the patients experienced only mild pain (NRS 0-4), although the majority developed mucositis grade 2-4 according to WHO mucositis index. Function-related pain intensity and opioid doses were highest during the sixth week of RT, with 3.67 (0-9) in NRS and 84 (0-430) mg oral morphine equivalents per day (median, range). At that same time point, significant positive correlations were found between the grade of mucositis and pain intensities. Patients with mucositis grade 2-4 were investigated further; in this subgroup, we found that opioid doses did not differ between patients with mild pain and patients with moderate to severe pain. Our multivariate data analysis defined a cluster of patients characterized by the presence of mucositis, cancer site in pharynx, concomitant chemotherapy, and the absence of surgery.

CONCLUSIONS

In HNC patients who were followed closely by pain care personnel during and after RT, pain was often satisfactorily alleviated with a structured use of opioids, including stepwise increases of fentanyl patches and oral morphine as needed. However, some patients with oral mucositis grade 2-4 experienced severe pain. Strong opioids, i.e. the third step of the WHO pain ladder, remain the mainstay of analgesic therapy in treating moderate to severe cancer-related pain, including patients with HNC. This real-life study indicates that RT-related pain is not a fatality. A proactive stance, monitoring these patients closely and regularly, is probably crucial in order to achieve good treatment results. Further studies are needed to develop better pain treatment strategies for those patients who develop severe oral mucositis-related pain despite intensive opioid treatment.

Are patient education and self-care advantageous for patients with head and neck cancer? A feasibility study

AIM

This study evaluates whether patient education and individually self-care reduces pain and improves QoL, mood and sleep during and after radiotherapy treatment for patients with head and neck cancer.

DESIGN

A longitudinal, two-armed feasibility study design was performed.

METHODS

Sixty-four participants with curative intent were included in the study. All participants answered questions about pain three times a week and completed a survey questionnaire about pain, QoL, psychological aspects and barriers towards pain management at baseline, at 4 weeks and at 10 weeks. Thirty-four of the participants attended in two education sessions on pain based on their beliefs about pain and received individualized self-care instructions based on their weekly rating of pain.

RESULT

This study did not find any significant group differences for the pain, QoL, mood and sleep.

Treatment of mucositis with combined 660- and 808-nm-wavelength low-level laser therapy reduced mucositis grade, pain, and use of analgesics: a parallel, single-blind, two-arm controlled study

Oral squamous cell carcinoma (OSCC) is the most frequent oral malignant neoplasia. As consequence of OSCC treatment, oral mucositis (OM) is one of the most common adverse effects of OSCC treatment. Currently, there is no consensus for OM treatment. The purpose of the current study was to test the combination of red and infrared low-level laser therapy (LLLT) for OM treatment. Primary culture of human fibroblast was performed to identify LLLT dose. After laboratory tests, a two-arm parallel, single-blind, controlled study was conducted. The two arms were group 1, both 660- and 808-nm wavelengths (300 J/cm², 9 J of total energy, 100 mW, spot size 3 mm²), and group 2, only 660-nm wavelength (300 J/cm², 9 J of total energy, 100 mW, spot size 3 mm²). Both treatments were performed twice a week. Group 1 presented a reduction of mucositis grade in comparison to group 2. Group 1 also presented reduction of analgesics prescription. But no significant differences between groups 1 and 2 were observed according to the pain scale. In conclusion, the current study demonstrated that a combination of red and infrared at a higher dose (300 J/cm²) reduced both oral mucositis grade and analgesics prescription. The effects of the combination of RT and LLLT are unclear and need more studies.
