The UK Divide: Does Having a Pembrolizumab-Chemotherapy Option in Head and Neck Cancer Matter? Real-world Experience of First-line Palliative Pembrolizumab Monotherapy and Pembrolizumab-Chemotherapy Combination in Scotland.

AIMS: The Scottish Medical Consortium recently approved first-line pembrolizumab monotherapy or in combination with chemotherapy for head and neck squamous cell carcinoma in the palliative setting, contrasting with the decision made by the National Institute for Health and Care Excellence, who approved monotherapy alone in England and Wales. The aim of this study was to provide real-world performance data for first-line pembrolizumab-containing treatments for head and neck squamous cell carcinoma in the palliative setting in Scotland. MATERIALS AND METHODS: We analysed the electronic records of patients who started pembrolizumab-containing treatment between 1 March 2020 and 30 September 2021. Outcomes included overall survival, progression-free survival (PFS), the duration of response and the disease control rate. Data were compared with the KEYNOTE-048 study and clinical factors were evaluated for association with survival. RESULTS: Our cohort included 91 patients (median follow-up 10.8 months). Patient characteristics were similar to those in the KEYNOTE-048 study, although our cohort had a higher proportion of patients with newly diagnosed, non-metastatic disease. For patients receiving monotherapy (n = 76), 12- and 24-month overall survival were 45% and 27%, respectively. For patients receiving pembrolizumab-chemotherapy (n = 15), 12-month overall survival was 60% (24-month overall survival had not yet been reached). Experiencing one or more immune-related adverse event (irAE; versus no irAEs), of any grade, was associated with favourable overall survival and PFS for patients receiving monotherapy in both univariable Log-rank analysis (median overall survival 17.4 months versus 8.6 months, respectively, P = 0.0033; median PFS 10.9 months versus 3.0 months, respectively, P < 0.0001) and multivariable analysis (Cox proportional hazards regression: overall survival hazard ratio 0.31, P = 0.0009; PFS hazard ratio 0.17, P < 0.0001). CONCLUSION: Our real-world data support the KEYNOTE-048 study findings and the value of combination treatment options. Additionally, our data show that irAEs of any grade, as reported in routine clinical records, are associated with better outcomes in this patient group, adding to the growing body of evidence showing that irAEs are generally a positive marker of programmed death-ligand 1 (PD-L1) inhibitor response.

Understanding the needs and preferences for cancer care among First Nations people: An integrative review.

AIM: This systematic review aimed to identify the needs and preferences for cancer care services among Australian First Nations people. DESIGN: Integrative review. DATA SOURCES: An integrative review was conducted. A wide range of search terms were used to increase the sensitivity and specificity of the searches in electronic databases. Methodological quality assessment, data extraction, was conducted independently by two reviewers, and a narrative synthesis was conducted. RESULTS: Forty-two studies were included. A total of 2965 Australian First Nations adults, both men and women of various ages across the lifespan, were represented; no First Nations children affected by cancer were represented in the studies. Three themes emerged which included: (1) discrimination, racism and trauma, resulting from colonization, directly impacted First National people's cancer care experience; (2) cultural ways of knowing, being and doing are fundamental to how First Nations people engage with cancer care services; and (3) First Nations people need culturally safe person-centred cancer care services that address practical needs. CONCLUSION: Most participants represented in this review experienced discrimination, racism and trauma, resulting from colonization, which directly negatively impacted Aboriginal peoples' cancer care experience. While the Optimal Cancer Pathway (OCP) was launched in Australia several years ago, people with cancer may continue to experience distressing unmet care needs. PATIENT OR PUBLIC CONTRIBUTION: Our team includes both First Nations people, non-First Nations researchers and healthcare professionals with expertise in cancer care. The researchers employed decolonizing restorative approaches to ensure voice, respect, accountability and reciprocity in this review work. IMPLICATIONS FOR NURSING PRACTICE: Members of the multidisciplinary team including nurses and policymakers should reflect on these findings, ensure that they have up-to-date cultural safety training and stand together with Indigenous and non-Indigenous cancer leaders to take proactive steps to stamp out and dismantle oppression in health, and safely implement the OCP.

To understand the experiences, needs, and preferences for supportive care, among children and adolescents (0-19 years) diagnosed with cancer: a systematic review of qualitative studies.

PURPOSE: This study aimed to understand the experiences, needs, and preferences for supportive care, among children and adolescents (0-19 years) diagnosed with cancer. METHODS: A qualitative systematic review has been reported according to PRISMA guidelines. A comprehensive search was conducted across multiple databases (APA PsycINFO, CINAHL, and Medline) and citation searches. Studies were screened according to pre-determined inclusion and exclusion criteria. Methodological quality was evaluated. Findings were extracted in relation to the context of interest of experiences, needs, and preferences of supportive care. Each finding was accompanied by a qualitative verbatim illustration representing the participant's voice. RESULTS: 4449 publications were screened, and 44 studies were included. Cancer populations represented in the included studies included lymphoma, leukaemia, brain cancer, sarcomas, and neuroblastoma. Two overarching synthesised findings were identified as (1) coping, caring relationships, communication, and impact of the clinical environment, and (2) experiences of isolation, fear of the unknown, restricted information, and changing self. Children and adolescents articulated that cancer care would be enhanced by developing a sense of control over their body and healthcare, being involved in communication and shared decision-making, and ensuring the clinical environment is age-appropriate. Many experienced a sense of disconnection from the rest of the world (including peers, school, and experiences of prejudice and bullying), and a lack of tailored support and information were identified as key unmet care needs that require further intervention. CONCLUSIONS: Children and adolescent who are diagnosed with cancer are a unique and understudied group in oncological survivorship research, with the slowest progress in improvement of care over time. This review will facilitate the development of future interventions and promote the importance of tailored support for children and adolescents at all stages of the cancer journey. IMPLICATIONS FOR CANCER SURVIVORS: Children and adolescents continue to experience a range of difficulties despite routine contact with cancer healthcare professionals. Children and adolescents should be carefully assessed about their individual circumstances and preferences for support given the clear implications from this review that "one size" does not fit all.

The Effects of Human Papillomavirus Status and Treatment on the Positive Predictive Value of Post-radiotherapy 18F-Fluorodeoxyglucose Positron Emission Tomography-Computed Tomography in Advanced Head and Neck Squamous Cell Carcinoma.

AIMS: The high negative predictive value of post-chemoradiation (CRT) positron emission tomography-computed tomography (PET-CT) is well established in head and neck squamous cell cancers (HNSCC). The positive predictive value (PPV) remains under scrutiny, with increasing evidence that it is affected by several factors. The aim of this study was to assess the PPV of post-treatment PET-CT for residual nodal disease when stratified by treatment modality and tumour human papillomavirus (HPV) status. MATERIALS AND METHODS: This was a retrospective cohort study in a tertiary oncology centre carried out between January 2013 and December 2019. Patients were radically treated with radiotherapy only/CRT for node-positive HNSCC. PET-CT nodal responses were categorised as complete, equivocal (EQR) or incomplete (ICR), and outcomes extracted from electronic records. RESULTS: In total, 480 patients were evaluated, all had a minimum potential follow-up of 2 years, with a median of 39.2 months. The PPV of 12-week PET-CT was significantly different between HPV-positive (22.5%) and HPV-unrelated (52.7%) disease, P < 0.001. It was also significantly different between the CRT (24.8%) and radiotherapy-only (51.1%) groups, P = 0.001. The PPV of an EQR was significantly less than an ICR, irrespective of HPV status and primary treatment modality. In HPV-positive disease, the PPV of an EQR was 9.0% for the CRT group compared with 21.4% for radiotherapy only, P = 0.278. The PPV in those who achieved an ICR was 34.2% in the CRT group, significantly lower than 70.0% in the radiotherapy-only group, P = 0.03. CONCLUSION: The PPV of 12-week PET-CT is significantly lower for HPV-positive compared with HPV-unrelated HNSCC. It is poorer in patients with HPV-positive disease treated with CRT compared with radiotherapy alone.

Current Landscape of Ecological Momentary Assessment (Real-Time Data) Methodology in Cancer Research: A Systematic Review.

OBJECTIVE: To critically synthesize and describe the use and methods of ecological momentary assessment (EMA) in cancer research. DATA SOURCES: A systematic review was conducted and has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) Guideline. Electronic databases (APA PsycINFO, CINAHL, Cochrane Central Register of Controlled Trials, MEDLINE, Scopus, and Web of Science Core Collection) were searched using a variety of keywords and subject headings by an expert systematic review librarian. All publications were double screened by two reviewers using predetermined exclusion and inclusion criteria throughout the full review process. The review used Covidence Systematic Review Software. Methodological quality assessment and data extraction were performed. A narrative synthesis was conducted to examine the aim for EMA, the characteristics of the study samples, the EMA sampling procedures, EMA completion rates, outcome measures, and any implications of findings for survivorship care. CONCLUSION: A total of 42 EMA studies in cancer were included. Most studies used an electronic mobile device to capture EMA data apart from several that used paper diaries. Existing studies were found to have significant heterogeneity in methods and widely varying approaches to design and self-report measurements. While EMA in cancer research holds significant promise to advance cancer care research into the future by increasing ecological validity and reducing retrospective bias and can capture the unique idiographic within-person change over time, in real-time, further research is needed to develop standardized EMA self-report questionnaires. IMPLICATIONS FOR NURSING PRACTICE: This is the first comprehensive systematic review to describe the use and methods of EMA in cancer research. There is significant heterogeneity in methods and widely varying approaches to design and self-report measurements in EMA cancer research. People affected by cancer found taking part in EMA studies reported benefit from the experience. However, researchers must engage with cancer survivors in the development and co-design of future EMA questionnaires to ensure relevant and acceptability of EMA data collection protocols.

Exploring Experiences Among People Diagnosed With Cancer During the COVID-19 Pandemic: A Qualitative Descriptive Study.

OBJECTIVES: To describe the experiences of people diagnosed with cancer during the COVID-19 pandemic. DATA SOURCES: Qualitative data were collected through semistructured interviews conducted with people affected by cancer in the Australian context. Following institutional ethical approval, interviews were conducted over Microsoft Teams and Zoom platforms and complied with confidentiality requirements. Data were transcribed verbatim and analyzed, and emergent themes were developed using thematic analysis to understand patient experiences of cancer care during the COVID-19 pandemic. CONCLUSIONS: The COVID-19 pandemic was disruptive to the daily experiences of supportive care. Four overarching themes were identified related to: 1) the impact on accessing healthcare services, 2) encounters with healthcare professionals, 3) the impact on daily living, and 4) the impact of COVID on psychological well-being. IMPLICATIONS FOR NURSING PRACTICE: As the COVID-19 pandemic held global consequences on cancer practices, it is recommended that nursing and other multidisciplinary healthcare professionals reflect upon these findings, in the context of planning for future pandemics. We encourage further exploration into the sustainability of telehealth services universally, given the issues highlighted in this study.

Scan-Associated Distress in People Affected by Cancer: A Qualitative Systematic Review.

OBJECTIVE: The term "scanxiety" has been coined to describe the anxiety commonly associated with individuals undergoing cancer-related imaging. Despite the prevalence and severity of scanxiety across various clinical and demographic populations, there remains a significant lack of qualitative insights from existing studies that effectively capture patients' experiences of scanxiety in their own words. Therefore, this review addresses the following research question: What are the experiences of scanxiety distress among people affected by cancer across the cancer care continuum? DATA SOURCES: Following the PRISMA methodology, a meta-aggregation of qualitative studies was performed, encompassing patients of all age groups who had been diagnosed with cancer or were indicated for a cancer-related scan. Of the 556 articles screened, 15 were deemed eligible for inclusion in the analysis. CONCLUSION: The three overarching themes of 1) experience of "scan-itis," 2) experience of "patient-clinician support," and 3) development of self-management strategies reveal the complex and interconnected factors that influence scanxiety in individuals undergoing cancer-related imaging. These findings emphasized distress experienced by patients during the waiting period for scan results, the act of viewing the results, and even the delivery of "bad" news. Consequently, patients expressed a strong desire for increased information, communication, and empathy from attending healthcare providers. Patients also report a myriad of self-coping strategies to manage their scanxiety well before, during, and after their scan appointment. IMPLICATIONS FOR NURSING PRACTICE: The study highlights the need for targeted interventions for those undergoing cancer-related scans, including increased awareness and education for health professionals regarding scanxiety.

Role of Adjuvant Radiotherapy in Acinic Cell Carcinoma of the Salivary Glands: A Systematic Review.

A systematic review was carried out to evaluate if adjuvant radiotherapy for acinic cell carcinomas (ACCs) of salivary glands improves survival. Twelve retrospective studies published between 2000 and 2020 that analysed the effect of radiotherapy on salivary gland neoplasms and ACCs of salivary glands and met the inclusion criteria were included in the review. The overall quality of the studies was moderate to low. There was no high-quality evidence for improved survival with radiotherapy for ACCs of the salivary gland. Some evidence suggests that there may be an advantage for patients with high-grade tumours, but these data should be interpreted with caution due to the small number of patients and low-quality evidence. Good quality of evidence is lacking. Recommendation for adjuvant radiotherapy for tumours with poor prognostic factors will require discussion and shared decision-making with the patients.

What are the experiences of supportive care in people affected by brain cancer and their informal caregivers: A qualitative systematic review.

PURPOSE: To critically synthesise qualitative research to understand experiences of supportive care in people affected by brain cancer and their informal caregivers. METHODS: A qualitative systematic review was conducted according to the Joanna Briggs methodology and has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Guidelines. Electronic databases were searched by an expert systematic review librarian for all qualitative studies irrespective of research design. All publications were double screened by two reviewers using a pre-determined exclusion and inclusion criteria. The review was managed using Covidence systematic review software. Methodological quality assessment and data extraction were performed. Qualitative findings accompanied by illustrative quotes from included studies were extracted and grouped into categories, which created the overall synthesised findings. RESULTS: A total of 33 studies were included which represented a total sample of 671 participants inclusive of 303 patients and 368 informal caregivers. There was a total of 220 individual findings included in this review, which were synthesised into two findings (1) caregivers and patients perceived supports which would have been helpful and (2) caregiver and patient experiences of unmet supportive care needs. CONCLUSION: This review highlighted the suffering and distress caused by brain cancer and associated treatments. Both patients and their informal caregivers experienced disconnect from themselves in renegotiating roles, and a profound sense of loneliness as the physical deterioration of the disease progressed. Both patients and informal caregivers reported similar unmet needs within the current service provision for brain cancer. However, what is apparent is that current cancer services are provided solely for patients, with little or no consideration to the support needs of both the patient and their informal caregiver. Service re-design is needed to improve care coordination with individualised informational support, implementation of holistic needs assessments for both the patients and their caregivers, better community support provision, improved opportunities for emotional care with early referral for palliative care services. IMPLICATIONS FOR CANCER SURVIVORS: It is recommended that members of the multidisciplinary brain cancer team reflect on these findings to target holistic needs assessments and develop shared self-management care plans for both the patient and the informal caregiver.

The unmet supportive care needs of people affected by cancer during the COVID-19 pandemic: an integrative review.

PURPOSE: To critically synthesise evidence regarding the supportive care needs of those living with cancer during the COVID-19 pandemic. METHODS: An integrative systematic review followed a pre-registered protocol, reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) Guidelines. We searched three databases (CINAHL, MEDLINE, and APA PsycINFO) using keywords and included all qualitative, quantitative, and mixed methods studies irrespective of research design published between December 2019 and February 2022. All articles were double screened according to a pre-determined eligibility criterion with reference lists of the final included studies checked for further studies. The review process was managed using Covidence systematic review software. Data from the studies were extracted, methodological quality appraisal conducted, and a narrative synthesis conducted. RESULTS: Eighteen publications were included. The findings identified that individuals affected by cancer reported a range of physical, psychological, social, and health system unmet needs during the global pandemic. Unique to the pandemic itself, there was fear of the unknown of the longer-term impact that the pandemic would have on treatment outcomes, cancer care follow-up, and clinical service delays. CONCLUSION: Many individuals living with cancer experienced unmet needs and distress throughout the different waves of the COVID-19 pandemic, irrespective of cancer type, stage, and demographic factors. IMPLICATIONS FOR CANCER SURVIVORS: We recommend clinicians use these findings to identify the individual person-centred needs to optimise recovery as we transition to the post-pandemic cancer care.

Identifying the unmet supportive care needs of individuals affected by testicular cancer: a systematic review.

PURPOSE: To critically appraise studies to identify experiences of unmet supportive care needs of individuals affected by testicular cancer. METHODS: A registered priori systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. CINAHL, PsycINFO, and MEDLINE were searched for quantitative, qualitative, and mixed methods studies using a wide range of search terms. All articles were double screened according to a pre-determined eligibility criterion. Reference lists of the final included studies were checked for further eligible studies. The review process was managed using Covidence systematic review software. Data from the studies were extracted, methodological quality appraisal conducted, and a narrative synthesis conducted. RESULTS: Of the 72 papers identified, 36 studies were included. In descending order of frequency of need, psychological needs were identified in 26/36, physical needs 18/36, interpersonal/intimacy needs 19/36, health system/information needs 11/36, cognitive needs 9/36, social needs 7/36, and of equal frequencies counts of 4/36 for family, practical, and patient-clinician information needs. Only one study explored spiritual needs and no daily living needs were identified. CONCLUSIONS: The experience of needs varied in terms of frequency and distress which were commonly influenced by the age of the individual across the cancer care continuum persisting after 1-year post-treatment. IMPLICATIONS FOR CANCER SURVIVORS: When caring for individuals affected by testicular cancer, clinicians are encouraged to take a holistic lens to cancer care, particularly to explore issue or concerns that young men affected by testicular cancer might be embarrassed or reticent to discuss.

How does Integrative Oncology Influence Patients' Physical and Psychosocial Outcomes, and What are Patients, Carers and Healthcare Professionals' Experiences? An Integrative Review.

OBJECTIVE: To identify the relationship between integrative oncology (IO) services on patients' physical and psychosocial outcomes and to explore the experiences of IO among patients, carers and healthcare professionals. DATA SOURCES: This integrative review was reported according to PRISMA guidelines. A search architecture was developed using key words and the following databases were searched: Medline (OVID), EmCare for Nurses (OVID), PsycINFO (OVID); AMED (OVID), CINAHL (EBSCO), Pubmed, the Cochrane Library (CCRT and CDSR) controlled trials databases and ANZ CTR. All articles were assessed according to a pre-determined selection criterion. 426 articles were assessed and 18 were included (4 qualitative, 9 quantitative and 5 mixed methods). CONCLUSION: Patients reported a reduction in some cancer related symptoms and treatment related side effects. Positive psychosocial impacts were reported such as an increased ability to cope with their cancer diagnosis and treatment. The experiences of healthcare professionals highlighted the importance of a collaborative approach among the Multi-Disciplinary Team (MDT), ongoing education and research to ensure Complementary Integrative Therapies (CIT) were evidence-based. IMPLICATIONS FOR NURSING PRACTICE: The provision of IO impacts positively on patients' self-reported physical and emotional wellbeing and quality of life at all stages of their cancer experience. Patients reported that IO supported their engagement in their own health and wellbeing by increasing feelings of control and empowerment. However, to successfully integrate CIT with conventional cancer treatments it is imperative that cancer centres adopt a collaborative and evidence-based informed approach to CIT.

Radionuclide ventriculography phase analysis for risk stratification of patients undergoing cardiotoxic cancer therapy.

BACKGROUND: Accurate diagnostic tools to identify patients at risk of cancer therapy-related cardiac dysfunction (CTRCD) are critical. For patients undergoing cardiotoxic cancer therapy, ejection fraction assessment using radionuclide ventriculography (RNVG) is commonly used for serial assessment of left ventricular (LV) function. METHODS: In this retrospective study, approximate entropy (ApEn), synchrony, entropy, and standard deviation from the phase histogram (phase SD) were investigated as potential early markers of LV dysfunction to predict CTRCD. These phase parameters were calculated from the baseline RNVG phase image for 177 breast cancer patients before commencing cardiotoxic therapy. RESULTS: Of the 177 patients, 11 had a decline in left ventricular ejection fraction (LVEF) of over 10% to an LVEF below 50% after treatment had commenced. This patient group had a significantly higher ApEn at baseline to those who maintained a normal LVEF throughout treatment. Of the parameters investigated, ApEn was superior for predicting the risk of CTRCD. Combining ApEn with the baseline LVEF further improved the discrimination between the groups. CONCLUSIONS: The results suggest that RNVG phase analysis using approximate entropy may aid in the detection of sub-clinical LV contraction abnormalities, not detectable by baseline LVEF measurement, predicting a subsequent decline in LVEF.

Identifying the supportive care needs of men and women affected by chemotherapy-induced alopecia? A systematic review.

PURPOSE: To systematically evaluate evidence regarding the unmet supportive care needs of men and women affected by chemotherapy-induced alopecia (CIA) to inform clinical practice guidelines. METHODS: We performed a review of CINAHL, MEDLINE, PsychINFO, Scopus, the Cochrane Library (CCRT and CDSR) controlled trial databases and clinicaltrials.gov from January 1990 to June 2019 according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Twenty-seven publications were selected for inclusion in this analysis. RESULTS: Included reports used qualitative (ten) and quantitative (17) studies. Across these studies men and women reported the major impact that CIA had on their psychological well-being, quality of life and body image. Hair loss had a negative impact irrespective of gender, which resulted in feelings of vulnerability and visibility of being a "cancer patient". Men and women described negative feelings, often similar, related to CIA with a range of unmet supportive care needs. CONCLUSIONS: Some patients are not well-prepared for alopecia due to a lack of information and resources to reduce the psychological burden associated with CIA. Hair loss will affect each patient and their family differently, therefore, intervention and support must be tailored at an individual level of need to optimise psychological and physical well-being and recovery. IMPLICATIONS FOR CANCER SURVIVORS: People affected by CIA may experience a range of unmet supportive care needs, and oncology doctors and nurses are urged to use these findings in their everyday consultations to ensure effective, person-centred care and timely intervention to minimise the sequalae associated with CIA.

Functional Imaging to Predict Treatment Response in Head and Neck Cancer: How Close are We to Biologically Adaptive Radiotherapy?

It is increasingly recognised that head and neck cancer represents a spectrum of disease with a differential response to standard treatments. Although prognostic factors are well established, they do not reliably predict response. The ability to predict response early during radiotherapy would allow adaptation of treatment: intensifying treatment for those not responding adequately or de-intensifying remaining therapy for those likely to achieve a complete response. Functional imaging offers such an opportunity. Changes in parameters obtained with functional magnetic resonance imaging or positron emission tomography-computed tomography during treatment have been found to be predictive of disease control in head and neck cancer. Although many questions remain unanswered regarding the optimal implementation of these techniques, current, maturing and future studies may provide the much-needed homogeneous cohorts with larger sample sizes and external validation of parameters. With a stepwise and collaborative approach, we may be able to develop imaging biomarkers that allow us to deliver personalised, biologically adaptive radiotherapy for head and neck cancer.

Prostate Cancer Prehabilitation and the Importance of Multimodal Interventions for Person-centred Care and Recovery.

BACKGROUND: Prostate cancer is the second most commonly diagnosed cancer globally. Cancer prehabilitation is defined as a process on the continuum of care that occurs between the time of a cancer diagnosis and the beginning of acute treatment. This article will discuss the importance of prostate cancer prehabilitation interventions in optimising physical and psychological recovery to enhance person-centred care. DATA SOURCES: Electronic databases including CINAHL, MEDLINE, PsychINFO, Scopus, professional websites, and grey literature were searched using Google Scholar. CONCLUSION: Prehabilitation in cancer care aims to enhance perioperative care and recovery. An emerging field of research suggests that the preoperative period may be physically and psychologically salient to introduce modifiable self-management behaviours to optimise overall recovery. IMPLICATIONS FOR NURSING PRACTICE: Prostate cancer specialist nurses provide the hub of person-centred care across the entire cancer care continuum embedded within the multidisciplinary team. Individually tailored interventions such as exercise and pelvic floor muscle training programmes, nutritional advice, anxiety and depression reduction, and sexual well-being interventions should be considered in the prehabilitation phase of the cancer care continuum.

An Exploration of the Rs of Radiobiology in Prostate Cancer.

OBJECTIVES: To explore the four Rs of radiobiology (Repair, Reoxygenation, Reassortment, and Repopulation) as a means to understand the effects of ionising radiation on biological tissue and subsequently as the basis for conventional fractionated treatment schedules. These radiobiological principles will form a rationale for combined regimens in prostate cancer treatment involving androgen deprivation therapy and radiation therapy and the associated toxicities of this approach will be discussed. DATA SOURCES: Electronic databases including CINAHL, MEDLINE, Scopus, professional websites, books and grey literature were searched using Google Scholar. CONCLUSION: It is important for nurses to understand the four Rs of radiobiology to grasp the effects of ionising radiation on biological tissue as the basis for conventional fractionated treatment schedules in prostate cancer. Men can experience a sequalae of physical and psychological side effects of treatment that can negatively impact quality of life. IMPLICATIONS FOR NURSING PRACTICE: Men can experience a range of unmet supportive care needs particularly related to informational, sexual, and psychological needs. For men affected by prostate cancer opting for radiation therapy (+/-) androgen deprivation therapy, nurses should ask targeted questions based on the Common Terminology Criteria for Adverse Events related to urinary and bowel function, potency and fatigue, and sexual health. We also recommend the use of holistic needs assessments to tailor self-management care plans. Evidence-based self-management advice should be provided in response to each man's unique needs.

Positron Emission Tomography-Computed Tomography Surveillance after (Chemo)Radiotherapy in Advanced Head and Neck Squamous Cell Cancer: Beyond the PET-NECK Protocol.

AIMS: To evaluate the implementation of 18-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) surveillance after (chemo)radiotherapy, to compare outcomes for those who achieved a complete (CR), equivocal (EQR) and incomplete (ICR) nodal response on 12-week PET-CT according to their human papillomavirus (HPV) status, and to assess the safety of ongoing surveillance beyond 12 weeks in the HPV-positive EQR group. MATERIALS AND METHODS: All patients with node-positive head and neck squamous cell carcinoma (HNSCC) treated with (chemo)radiotherapy between January 2013 and September 2017 were identified. PET-CT responses were classified as CR, ICR or EQR. Patient outcomes were obtained from electronic records. RESULTS: In total, 236 patients with a minimum of 2 years of follow-up were identified. The mean age was 59 years; 79.3% had N2 disease; 77.1% of patients had oropharyngeal cancer and 10.1% had squamous cell carcinoma of unknown primary, of whom 82.0% (169) were HPV positive; 78.0% received chemoradiotherapy. The median time from the end of radiotherapy to PET-CT was 91 days. Of the HPV-related HNSCC, 60.4% achieved CR, 29.0% EQR and 10.6% ICR. With a median follow-up of 41.7 months, there was no difference in survival between patients with HPV-related HNSCC achieving CR and EQR (median overall survival not reached for both, P = 0.67) despite the omission of immediate neck dissection in 98.0% of the EQR group. CONCLUSION: Patients with HPV-positive HNSCC who have achieved EQR have comparable survival outcomes to those who achieved a CR despite the omission of immediate neck dissections; this shows the safety of ongoing surveillance beyond 12 weeks in this group of patients.

Radiotherapy-induced xerostomia: a randomised, double-blind, controlled trial of Visco-ease™ oral spray compared with placebo in patients with cancer of the head and neck.

Radiotherapy-induced xerostomia (RIX) is a common and untreatable side effect of radiotherapy to the head and neck. Visco-ease™ mouth spray (Lamellar Biomedical Ltd), a new product that is made from lamellar body mimetics, reduces the viscosity of saliva ex vivo. The purpose of this study was to evaluate its safety and effectiveness in the treatment of RIX in 43 patients with cancer of the head and neck. They were randomised into the Visco-ease™ or placebo groups, and asked to complete the Groningen radiotherapy-induced xerostomia (GRIX) questionnaire each week. The primary endpoint was a change in GRIX score from baseline to end of treatment. There was no difference in scores between the two groups, and none of the patients had device-related serious adverse events. Visco-ease™ oral spray was safe and tolerable but no better than placebo in reducing RIX in this group of patients.
