[PMID: 37946598 DOI: 10.1111/odi.14804] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 08/01/2023] [Accepted: 10/12/2023] [Indexed: 11/12/2023]
Abstract
OBJECTIVES Radiation-induced dry mouth negatively impacts patients' oral health and quality of life. Currently, evidence-based recommendation for non-pharmacologic interventions is still lacking. This study aimed to systematically review clinical trials evaluating the efficacy of non-pharmacologic interventions in cancer patients with radiation-induced dry mouth. METHODS Randomized controlled trials from 2000 were searched from 4 databases, including MEDLINE, Cochrane, Embase via OVID, and SCOPUS, up to December 16th, 2022 (PROSPERO registration CRD42022378405). The risk of bias was assessed using the revised Cochrane risk of bias assessment tool. RESULTS Twenty-one studies were included: 11 on artificial saliva, 4 on electrical nerve stimulation (TENS), 2 on acupuncture, and one study each on low-level laser therapy, stem cells, chewing gum, and probiotics. Overall bias was low, medium, and high in 33%, 48%, and 19% of the studies, respectively. Certain artificial saliva products and TENS were shown to improve dry mouth symptoms and salivary flow rate (SFR). One study showed that stem cell transplantation significantly increased SFR. CONCLUSIONS The evidence suggested that certain artificial saliva products and TENS are promising management. However, the evidence was still limited due to heterogeneity of interventions and outcome measurements. Thus, future studies using standard measurements and long-term follow-up are warranted.

Non-pharmacological strategies to alleviate dysgeusia in patients undergoing chemotherapy: A systematic review. Eur J Oncol Nurs 2024; 70:102569. [PMID: 38593535 DOI: 10.1016/j.ejon.2024.102569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2024] [Revised: 03/10/2024] [Accepted: 03/16/2024] [Indexed: 04/11/2024]
Abstract
PURPOSE Dysgeusia is a common side effect in oncology patients, significantly impacting their quality of life. This systematic review aims to evaluate the effectiveness of non-pharmacological strategies in treating dysgeusia in patients undergoing chemotherapy or radiotherapy. METHODS Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a comprehensive literature search across five databases: PubMed, Embase, Cochrane Library, CINAHL, and the British Nursing Database. We used the Joanna Briggs Institute Critical Appraisal Tools to assess the quality of the included studies. A harvest plot was used to synthesise evidence about the differential effects of population-level interventions. RESULTS Nine studies of non-pharmacological strategies to manage dysgeusia were included. These studies encompassed a variety of interventions, including oral applications and supplements, instrumental techniques, and educational programs. The review identified promising interventions such as cryotherapy and Miraculine supplementation, which showed potential in mitigating taste alterations. Instrumental techniques like photobiomodulation therapy and complementary and integrative medicine approaches, including acupuncture and herbs, were also found to be beneficial. Educational and self-management strategies emerged as effective interventions for empowering patients to manage dysgeusia. Despite the diversity of interventions and the limitations of the included studies, such as small sample sizes and geographical differences, these findings underscore the potential of non-pharmacological strategies in managing dysgeusia. CONCLUSION The results support the integration of these strategies into clinical practice, highlighting the importance of multidisciplinary approaches to improve patient care. Further research should prioritize rigorous studies to enhance evidence and explore long-term effects.

Abstract
BACKGROUND Cancer is one of the leading causes of death in most countries with an expected increased burden on healthcare systems. Since integrative medical treatments are not collected within the scope of existing cancer registries, the establishment of the Korean Medicine Cancer Registry (KMCARE), gathering integrative therapies, including conservative care and Korean medicine, is warranted. METHODS A prospective observational study based on the registry will be conducted in 5 Korean medical hospitals. A total of 650 eligible participants undergoing Korean medicine treatments within 1 month of a diagnosis of lung, colorectal, stomach, or breast cancer are anticipated to be enrolled in the registry. Data collected in the KMCARE can be classified into patient information, received treatments, and outcomes. The primary outcome is the Functional Assessment of Cancer Therapy-General Questionnaire score at 3 months. Secondary outcomes include the MD Anderson Symptom Inventory-Core and the Body Constitution Questionnaire at 3 and 6 months. After 6 months of follow-up periods, survival surveillance will be continued for additional 18 months. Descriptive and statistical analysis of primary and secondary outcomes, baseline data, safety, survival, and prognostic factors will be performed. DISCUSSION This is the first prospective, multi-centered, registry-based observational study of cancer patients in Korean medicine hospitals, which could reveal the current status of cancer patients receiving integrative cancer therapies, and provide better insight into the role of Korean medicine in palliative care for patients with cancer.

[PMID: 38140327 PMCID: PMC10745914 DOI: 10.3390/nu15245068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 12/06/2023] [Accepted: 12/07/2023] [Indexed: 12/24/2023] Open
Abstract
Throughout their experience of illness and during the course of treatment, a substantial proportion of cancer patients are prone to develop nutritional and/or metabolic disturbances. Additionally, cancer patients often encounter long-term side effects from therapies, which may lead to impaired digestion, nutrient absorption or bowel motility. Therefore, the preservation and maintenance of an optimal and balanced nutritional status are pivotal to achieving a better prognosis, increasing the tolerance and adherence to cancer therapies and improving the overall quality of life. In this context, personalized nutritional programs are essential for addressing conditions predisposing to weight loss, feeding difficulties, digestion problems and intestinal irregularity, with the goal of promoting adequate nutrient absorption and minimizing the detrimental effects of treatment regimens. The focus of this research is to examine the most common clinical conditions and metabolic changes that cancer patients may experience, including stomatitis, xerostomia, diarrhea, nausea, vomiting, dysphagia, sub-occlusion, dysgeusia, dysosmia, anorexia, and cachexia. Furthermore, we present a pragmatic example of a multidisciplinary workflow that incorporates customized recipes tailored to individual clinical scenarios, all while maintaining the hedonic value of the meals.

Clinical management of salivary gland hypofunction in patients with head and neck cancer: a scoping review of physical salivary stimulation methods. Oral Surg Oral Med Oral Pathol Oral Radiol 2023; 136:442-458. [PMID: 37380576 DOI: 10.1016/j.oooo.2023.05.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Revised: 04/25/2023] [Accepted: 05/11/2023] [Indexed: 06/30/2023]
Abstract
OBJECTIVE(S) This scoping review aims to map the scientific literature on the therapies currently available for physical salivary stimulation in individuals with hyposalivation caused by radiotherapy. STUDY DESIGN Studies were included when they comprised the target population of adult individuals receiving radiotherapy of the head and neck region and who developed or were at risk of developing hyposalivation. Two reviewers selected the studies and extracted data on the type of physical salivary stimulation therapy used, the degree of glandular tissue involvement, and the percentage of salivary flow alteration. Therapies were classified according to either prophylactic application (before/during radiotherapy) or therapeutic application (post-radiotherapy). RESULTS Sixteen articles were included: 4 tested transcutaneous electrical nerve stimulation (TENS), 3 studied low-level lasers, 7 researched acupunctures, and 2 investigated acupuncture-like TENS. The outcomes of the prophylactic studies indicated beneficial effects (similar salivary flow or reduced salivary flow loss), although most studies did not include a comparable control group. Therapeutic studies presented conflicting results. CONCLUSION(S) Prophylactic therapies of physical salivary stimulation may produce better effects than therapeutic applications. However, the protocols best indicated could not be defined. Well-designed, controlled clinical trials should be researched in the future to support the clinical recommendation of any of these treatments.

Abstract
Many patients with cancer make use of complementary medicine alongside conventional medicine, but clinicians in oncology often lack the knowledge to adequately advise patients on the evidence base for complementary therapies. This study aims to provide an overview of recently published systematic reviews that assess the effects of complementary therapies on patient-reported health outcomes in patients with cancer. Systematic reviews, including a meta-analysis of at least two randomized controlled trials, were identified from the PubMed, Embase, Cochrane Library, CINAHL and PsycINFO databases. The methodological quality was assessed with AMSTAR 2. One hundred systematic reviews were included. The results suggest that several complementary therapies can improve health outcomes reported by patients with cancer, such as acupuncture to relieve pain, music interventions to reduce anxiety and yoga to improve cancer-related fatigue. The side effects related to complementary therapy use are generally mild. The results remain inconclusive for some intervention-outcome combinations. Many of the included systematic reviews insufficiently assessed the causes and impact of bias in their interpretation of the results. This overview of systematic reviews can support clinicians in counselling their patients on this topic and provide directions for future research and clinical practice guidelines in the field of complementary medicine.

Abstract
Radiotherapy and chemotherapy can impair salivary gland (SG) function, which causes xerostomia and exacerbate other side effects of chemotherapy and oral infection, reducing patients' quality of life. This animal study aimed to assess the efficacy of electroacupuncture (EA) as a means of preventing xerostomia induced by 5-fluorouracil (5-FU). A xerostomia mouse model was induced via four tail vein injections of 5-FU (80 mg/kg/dose). EA was performed at LI4 and LI11 for 7 days. The pilocarpine-stimulated salivary flow rate (SFR) and salivary glands weight (SGW) were recorded. Salivary immunoglobulin A (SIgA) and lysozyme were determined via enzyme-linked immunosorbent assay (ELISA). SG was collected for hematoxylin and eosin staining to measure acini number and acinar cell size. Tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and aquaporin 5 (AQP5) mRNA expressions in SG were quantified via RT-qPCR. 5-FU caused significant decreases in SFR, SGW, SIgA, lysozyme, AQP5 expression, and acini number, while TNF-α and IL-1β expressions and acinar cell size were significantly increased. EA treatment can prevent 5-FU damage to the salivary gland, while pilocarpine treatment can only elevate SFR and AQP5 expression. These findings provide significant evidence to support the use of EA as an alternative treatment for chemotherapy-induced salivary gland hypofunction and xerostomia.

Abstract
INTRODUCTION Esophagus cancer patients are at risk for malnourishment. Feeding jejunostomy is used in advanced esophagus cancer patients in order to support and supplement the patients' nutrition needs. In dumping syndrome, the food is rapidly introduced into the intestine at a rate that is faster than normal, it is associated with both digestive system and vasoactive symptoms. Dumping syndrome has an association with both esophagus cancer patients and feeding jejunostomy. In the mid and long term, dumping syndrome is an important issue that contributes to the risk of malnourishment in advanced esophagus cancer patients. In recent studies, acupuncture was effective in regulating digestive symptoms. Acupuncture is considered to be a safe intervention, that was previously shown to be effective in treating digestive-related symptoms. METHODS Sixty advanced esophageal cancer patients post-feeding jejunostomy will be divided into 2 equal groups, an intervention group (n = 30) and a control group (n = 30). Patients in the intervention group will receive acupuncture using the following acupoints: ST36 (Zusanli), ST37 (Shangjuxu), ST39 (Xiajuxu), PC6 (Neiguan), LI4 (Hegu), and Liv 3 (Taichung). Patients in the control group will receive shallow acupuncture on 12 non-acupoints (sham points), 1 cm from the above mention points. Patients and assessors will be blind to trial allocation. Both groups will receive acupuncture twice a week for 6 weeks. The main outcome measurements are: body weight, BMI, Sigstad's score, and the Arts' dumping questionnaire. DISCUSSION There are no previous studies that have examined the use of acupuncture on patients with dumping syndrome. This single-blind randomized control trial will investigate the effect of acupuncture on dumping syndrome in advanced esophagus cancer patients with feeding jejunostomy. The results will determine if verum acupuncture can affect dumping syndrome and prevent weight loss.

Abstract
Acupuncture is a common part of complementary medicine. However, traditional Chinese acupuncture has been built on concepts which are not in accordance with science-based medicine. Our aim was to critically assess the evidence presented in systematic reviews (SRs) and meta-analyses (MAs) about the effectiveness of acupuncture on radiotherapy induced xerostomia. A systematic search was conducted in February 2022. We evaluated all SRs/MAs using the AMSTAR-2 instrument. Eight SRs, with 12 controlled studies were included. All SRs summarize that the methodological drawbacks do not allow to give a clear statement about the effectiveness of acupuncture. While objective assessments in most SRs/MAs reported no difference between real and sham acupuncture, some favorable effects on subjective xerostomia symptoms are found. No clinical meaningful effectiveness of acupuncture on xerostomia has been proven so far, but positive subjective findings need to be explored more. While most SRs recommend further studies, studies involving patients with a serious cancer diagnosis are ethically questionable.

Methods Eligible randomized controlled trials (RCTs) were collected from inception to June 2020 from 9 bibliographic databases. The risk of bias evaluation of the analyzed literature was carried out using the Cochrane risk-of-bias tool. Network meta-analysis was mainly performed using STATA 14.2 and OpenBUGS 3.2.3 by figuring out the network diagrams, league figures, and SUCRA values. Results A total of 41 studies with 3,011 participants reported data suitable for network meta-analysis. There was a low to moderate risk of bias in twenty of the articles. ST36 was the most widely prescribed acupoint. Based on network meta-analysis, four outcome indicators were described, namely, acupuncture + medication ranked first in treating radiation enteritis, moxibustion + medication ranked first in preventing radiotherapy-induced leukopenia, acupuncture + medication ranked first in preventing radioactive oral mucositis, and acupuncture ranked first in improving the stimulated salivary flow rate of radioactive xerostomia. Conclusion The findings of the network meta-analysis manifested that acupuncture therapy combined with medication has superiority in most RIAEs, both reducing incidence and relieving symptoms. However, high-quality studies are still needed to provide conclusive evidence. Systematic review registration https://inplasy.com/inplasy-2020-7-0054/, identifier: INPLASY202070054.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 106:154430. [PMID: 36099656 DOI: 10.1016/j.phymed.2022.154430] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 06/24/2022] [Accepted: 09/01/2022] [Indexed: 02/05/2023]
Abstract
BACKGROUND Acupuncture is commonly used for cancer-related conditions worldwide, and evidence is increasing year on year. There is a need to summarize the evidence of acupuncture for cancer-related conditions comprehensively and critically. OBJECTIVE To evaluate and summarize the systematic reviews (SRs) that assess the effects and safety of acupuncture for cancer-related conditions, and to inform clinical practice and future studies. METHODS A comprehensive search was conducted on Pubmed, Embase, the Cochrane Library, Web of Science, CNKI, VIP, Sinomed, and Wanfang from their inception to October 16, 2021. SRs of randomized controlled trials (RCTs) on acupuncture for cancer-related conditions were to be included. Two reviewers screened the eligible articles, and four reviewers in pair extracted data and assessed the methodological quality/risk of bias of all included reviews by AMSTAR 2 and ROBIS tools. The overlap of primary studies was measured by calculating corrected covered areas. Data from the included reviews were synthesized with a summary of meta-analysis or narrative description. RESULTS Fifty-one SRs of RCTs on acupuncture for cancer-related conditions were included and synthesized. The methodological quality of SRs included 1 "high", 5 "low" and 45 "very low" by AMSTAR 2. Sixteen SRs assessed as low risk of bias (31.37%), and 35 SRs had high risk of bias (68.63%) by ROBIS. Acupuncture showed effective on systemic conditions in relation to different cancers, including cancer-related pain (17 SRs, 80 RCTs), fatigue (7 SRs, 18 RCTs), insomnia (4 SRs, 10 RCTs), quality of life (2 SRs, 15 RCTs); conditions in relation to chemo-radiotherapy, including nausea and vomiting (3 SRs, 36 RCTs) and bone marrow suppression (2 SRs, 21 RCTs); and conditions in relation to specific cancers, including breast cancer-related menopause (3 SRs, 6 RCTs), hot flashes (12 SRs, 13 RCTs), arthralgia (5 SRs, 10 RCTs), and nasopharyngeal cancer-related dysphagia (1 SRs, 7 RCTs). Acupuncture appeared to have benefit for patients with lymphoedema (3 SRs, 3 RCTs), gastrointestinal function (5 SRs, 27 RCTs), and xerostomia (4 SRs, 7 RCTs). Limited evidence showed inconsistent results on acupuncture for chemotherapy-induced peripheral neuropathy (3 SRs, 6 RCTs), depression and anxiety (3 SRs, 9 RCTs). Acupuncture was regarded as a safe therapy for cancer patients as no severe adverse events related were reported. CONCLUSION Evidence from SRs showed that acupuncture is beneficial to cancer survivors with cancer-related pain, fatigue, insomnia, improved quality of life, nausea and vomiting, bone marrow suppression, menopausal symptoms, arthralgia, and dysphagia, and may also be potential for lymphoedema, gastrointestinal function, and xerostomia. For neuropathy, depression and anxiety, acupuncture should be used as an option based on individual conditions. Acupuncture is relatively safe without serious adverse events. More well-designed clinical trials of acupuncture are recommended on cancer-related depression and anxiety, arthralgia, xerostomia, gastrointestinal dysfunction and dysphagia.

Abstract
OBJECTIVES Since pre-existing expectations, that is, beliefs, in a treatment may modify outcomes, and acupuncture studies often fail to measure expectations, we wanted to investigate the use of acupuncture, interest, and belief in acupuncture effects among patients undergoing cancer therapy. METHOD A cross-sectional design, where the participants answered a study-specific questionnaire with questions regarding their use of, interest and belief in acupuncture treatment. RESULTS A total of 457 patients with cancer (48% men, mean age 65 years) answered the questionnaire. Acupuncture was used by 4 (1%) patients during their cancer therapy, and 368 (83%) expressed an interest in receiving acupuncture. Of the 457 patients, 289 (63%) believed acupuncture to be effective for at least 1 of 17 requested symptoms, most commonly pain (56% of the patients) and muscle tension (40%). They believed acupuncture to be effective for a mean value 3 of the 17 requested symptoms. Women (P < .001), and patients 41 to 65 years (P < .001), expressed a stronger belief in acupuncture effects than others. CONCLUSIONS Men and older patients expressed weaker beliefs in acupuncture effects than other patients, indicating the importance of collecting expectancy data in future randomized sham-controlled acupuncture studies to be able to treat expectancy as an effect-modifier. The high interest and beliefs in acupuncture effects found also indicate that acupuncture should be available for patients with cancer, for side effects where acupuncture has shown to be effective. In a clinical setting, older men might need more encouragement regarding positive expected outcomes of the acupuncture treatment than younger women.

Abstract
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.

The relationship between the severity of oral dryness and the use of dry-mouth interventions by various subgroups of dry-mouth patients. Clin Oral Investig 2022; 26:3097-3108. [PMID: 35006295 DOI: 10.1007/s00784-021-04292-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 11/10/2021] [Indexed: 11/03/2022]
Abstract
OBJECTIVE Dry-mouth patients use different interventions to relieve their oral dryness. As recent studies showed that various subgroups of dry-mouth patients perceived different intra-oral regions as most dry, the present study investigated whether the use of dry-mouth interventions by various subgroups of dry-mouth patients was related to the perceived oral dryness as well as salivary flow rate. MATERIALS AND METHODS Xerostomia Inventory (XI) scores, Regional Oral Dryness Score (RODI) scores and used dry-mouth interventions were extracted from the medical records of 528 patients visiting a saliva clinic. Based on their medical history, they were allocated into 6 subgroups. RESULTS The subgroups of dry-mouth patients used a wide range of interventions to relieve their oral dryness. Sjögren's syndrome patients used most interventions more frequently than patients with oral dryness due to use of a limited number of medications and controls. Patients using medications showed associations between the total XI score and dry-mouth interventions aimed at the entire mouth. In medication using patients and controls, the locally applied intervention "using mouth gel" was associated with RODI scores of the anterior tongue. CONCLUSION The use of dry-mouth interventions was associated with dry-mouth feelings. Use of interventions aimed to relieve dryness of the entire mouth was significantly associated with total XI score, while locally applied interventions were significantly associated with the severity of dryness at specific intra-oral regions, the anterior tongue in particular. CLINICAL RELEVANCE The results will help clinicians to advise dry-mouth patients about the most suitable interventions for relief of oral dryness complaints.

A nomogram for predicting late radiation-induced xerostomia among locoregionally advanced nasopharyngeal carcinoma in intensity modulated radiation therapy era. Aging (Albany NY) 2021; 13:18645-18657.

Abstract
Background: Dry mouth sensation cannot be improved completely even though parotids are spared correctly. Our purpose is to develop a nomogram to predict the moderate-to-severe late radiation xerostomia for patients with locoregionally advanced nasopharyngeal carcinoma (LA-NPC) in intensity modulated radiation therapy (IMRT) / volumetric modulated arc radiotherapy (VMAT) era. Methods: A dataset of 311 patients was retrospectively collected between January 2010 and February 2013. The binary logistic regression was to estimate each factor’s prognostic value for development of moderate-to-severe patient-reported xerostomia at least 2 years (Xer2y) after completion of radiotherapy. Therefore, we can develop a nomogram according to binary logistic regression coefficients. This novel model was validated by bootstrapping analyses. Results: Contralateral Parotid mean dose (coMD<24.4Gy), VMAT (yes), and platinum-based concurrent chemoradiotherapy (no) were significantly related to patient-reported xerostomia at least 2 years (Xer2y) (all p < 0.001), and were included in the nomogram. Receiver operating characteristic (ROC) analysis revealed AUC (area under the ROC curve) with the value of 0.811 (0.710-0.912) of the nomogram, which was significantly higher than coMD 0.698 (0.560-0.840) from QUANTEC2010 (p<0.001). Calibration plots illustrated that the predicted Xer2y was close to the actual observation, and decision curve analyses (DCA) indicated valid positive net benefits. Conclusion: We developed a feasible nomogram to predict patient-rated Xer2y based on comprehensive individual data in patients with LA-NPC in the real world. The proposed model is able to facilitate the development of treatment plan and quality of life improvement.
