MASCC/ISOO Clinical Practice Statement: Management of salivary gland hypofunction and xerostomia in cancer patients

PURPOSE

A MASCC/ISOO Clinical Practice Statement (CPS) is aimed at generating a concise tool for clinicians that concentrates practical information needed for the management of oral complications of cancer patients. This CPS is focused on the management of salivary gland hypofunction and xerostomia in cancer patients.

METHODS

This CPS was developed based on critical evaluation of the literature followed by a structured discussion of a group of leading experts, members of the Oral Care Study Group of MASCC/ISOO. The information is presented in the form of succinct bullets and tables to generate a short manual about the best standard of care.

RESULTS

Salivary gland hypofunction and xerostomia in cancer patients are managed by (i) stimulating saliva production of salivary glands with residual secretory capacity or (ii) artificial wetting of the oral and lip surfaces which can be achieved by pharmacological or non-pharmacological interventions. Pharmacological interventions encompass the use of sialagogues and sialolytics, while non-pharmacological interventions involve the use of moistening agents, mechanical, gustatory, or electrostimulation of the salivary glands. Additional treatment modalities may be incorporated in practice based on local availability and the clinician's experience.

CONCLUSION

The information presented in this CPS offers clinicians convenient access to the dosages and regimens of different interventions for managing salivary gland hypofunction or xerostomia to facilitate clinical efficiency and conserve valuable time for clinicians.

Effect of Honey-Lime Spray as Add-On Therapy on Chemotherapy-Induced Xerostomia in Breast Cancer Patients: A Pilot Randomized Double-Blinded Controlled Trial

INTRODUCTION

Xerostomia (dry mouth) is a common side effect among patients with cancer undergoing chemotherapy. There is no standard treatment for this symptom yet, although Persian medicine textbooks suggested some products to relieve xerostomia. We aimed to assess the efficacy of honey-lime spray in treating chemotherapy-induced xerostomia in breast cancer patients through a controlled study.

METHODS

In this pilot, randomized, double-blinded clinical trial conducted in Shohadaye Tajrish Hospital, Iran, the intervention group received honey-lime spray and nystatin, while the control group used distilled water plus nystatin for 2 weeks. The six-item dry mouth form and visual analog score (VAS) were used to evaluate xerostomia extent and pain, respectively.

RESULTS

The standardized value of the difference between the mean scores before and after the study was -10.21 (p < 0.001), and the effect size was estimated at 55%. Also, VAS showed a significant decrease in pain for the intervention group compared with the control group (p < 0.001). There were no serious side effects.

CONCLUSION

Honey-lime spray may be a good treatment choice for xerostomia in chemotherapy-induced breast cancer patients, but robust trials with larger samples and prolonged follow-ups are highly recommended.

Einleitung

Mundtrockenheit (Xerostomie) ist eine häufige Nebenwirkung bei Krebspatienten, die sich einer Chemotherapie unterziehen. Es gibt bisher keine Standardtherapie für dieses Symptom, doch Lehrbücher der persischen Medizin schlagen einige Mittel zur Linderung von Mundtrockenheit vor. Unser Ziel war es, die Wirksamkeit von Honig-Limetten-Spray zur Behandlung von chemotherapiebedingter Mundtrockenheit bei Patientinnen mit Brustkrebs im Rahmen einer kontrollierten Studie zu untersuchen.

Methoden

In dieser randomisierten, doppelt verblindeten klinischen Pilotstudie, die im Shohadaye Tajrish Hospital im Iran durchgeführt wurde, erhielt die Interventionsgruppe zwei Wochen lang Honig-Limetten-Spray und Nystatin und die Kontrollgruppe destilliertes Wasser plus Nystatin. Ein Mundtrockenheits-Fragebogen mit sechs Items wurde zur Beurteilung der Schwere der Mundtrockenheit verwendet und eine visuelle Analogskala zur Beurteilung der Schmerzen.

Ergebnisse

Der standardisierte Wert der Differenz zwischen den mittleren Scores vor und nach der Studie betrug −10,21 (p < 0,01), und die geschätzte Effektstärke betrug 55%. Zudem zeigte die VAS eine signifikante Abnahme der Schmerzen in der Interventionsgruppe im Vergleich zur Kontrollgruppe (p < 0,01). Es traten keine schwerwiegenden Nebenwirkungen auf.

Schlussfolgerung

Honig-Limetten-Spray könnte eine gute Wahl für die Behandlung von Mundtrockenheit bei Brustkrebspatientinnen unter Chemotherapie sein, doch hierzu werden belastbare Studien mit größerem Probenumfang und längerer Nachbeobachtung nachdrücklich empfohlen.

Complementary and Integrative Medicine in Head and Neck Cancer

Complementary/integrative medicine (CIM) is an evolving area of collaboration between oncology, patient and their beliefs, and practitioners of complementary medicine. Evidence-informed decision-making is necessary to advise patients on which treatments may be incorporated into standard of care treatments for cancer. Patients use CIM for a variety of reasons and often have unrealistic expectations of cure or disease modifications; on the other hand, there is increasing evidence that symptoms, side effects, and dysfunction related to cancer and its treatment can be ameliorated by CIM approaches to improve patient satisfaction and quality of life. Open communication between patients and providers is paramount.

Diagnosis, Prevention, and Treatment of Radiotherapy-Induced Xerostomia: A Review

In patients with head and neck cancer, irradiation (IR)-sensitive salivary gland (SG) tissue is highly prone to damage during radiotherapy (RT). This leads to SG hypofunction and xerostomia. Xerostomia is defined as the subjective complaint of dry mouth, which can cause other symptoms and adversely affect the quality of life. In recent years, diagnostic techniques have constantly improved with the emergence of more reliable and valid questionnaires as well as more accurate equipment for saliva flow rate measurement and imaging methods. Preventive measures such as the antioxidant MitoTEMPO, botulinum toxin (BoNT), and growth factors have been successfully applied in animal experiments, resulting in positive outcomes. Interventions, such as the new delivery methods of pilocarpine, edible saliva substitutes, acupuncture and electrical stimulation, gene transfer, and stem cell transplantation, have shown potential to alleviate or restore xerostomia in patients. The review summarizes the existing and new diagnostic methods for xerostomia, along with current and potential strategies for reducing IR-induced damage to SG function. We also aim to provide guidance on the advantages and disadvantages of the diagnostic methods. Additionally, most prevention and treatment methods remain in the stage of animal experiments, suggesting a need for further clinical research, among which we believe that antioxidants, gene transfer, and stem cell transplantation have broad prospects.

State of Rehabilitation Research in the Head and Neck Cancer Population: Functional Impact vs. Impairment-Focused Outcomes

PURPOSE OF REVIEW

Management of head and neck cancer (HNC) typically involves a morbid combination of surgery, radiation, and systemic therapy. As the number of HNC survivors grows, there is growing interest in rehabilitation strategies to manage HNC-related comorbidity. In this review, we summarize the current state of HNC rehabilitation research.

RECENT FINDINGS

We have organized our review using the World Health Organization's International Classification of Function (ICF) model of impairment, activity, and participation. Specifically, we describe the current research on rehabilitation strategies to prevent and treat impairments including dysphagia, xerostomia, dysgeusia, dysosmia, odynophagia, trismus, first bite syndrome, dysarthria, dysphonia, lymphedema, shoulder syndrome, cervicalgia, cervical dystonia and dropped head syndrome, deconditioning, and fatigue. We also discuss the broader impact of HNC-related impairment by exploring the state of rehabilitation literature on activity, participation, psychosocial distress, and suicidality in HNC survivors. We demonstrate that research in HNC rehabilitation continues to focus primarily on impairment-driven interventions. There remains a dearth of HNC rehabilitation studies directly examining the impact of rehabilitation interventions on outcomes related to activity and participation. More high-quality interventional studies and reviews are needed to guide prevention and treatment of functional loss in HNC survivors.
