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

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 clinical assessment of salivary gland hypofunction and xerostomia in cancer patients. This CPS was developed based on a 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. The objective assessment of saliva secretion involves an extra- and intra-oral clinical examination while the subjective assessment involves eliciting information on the patient's complaint of xerostomia and its impact on daily functioning. This CPS summarizes the common investigator- and patient-reported instruments used in clinical practice for assessing salivary gland hypofunction and xerostomia in cancer patients. There is a range of tools to assess salivary gland function in patients undergoing cancer therapy, patients recovering from cancer therapy, or cancer survivors. Clinicians should ideally conduct both objective and subjective measurements to ensure a clear understanding about the status of the patients in order to provide the most appropriate treatment.

Comparative Study of Morphine, Fentanyl or Nalbuphine Patient Controlled Analgesia (PCA) for Mucositis Pain in Pediatric Patients Undergoing Cancer Therapy. A Prospective Randomized Clinical Trial

Abstract Background Cancer treatment may cause several side effects, including severe oral mucositis (SOM). Oral mucositis is an inflammation of the oral mucosa that causes severe pain and ulceration. Children and adolescents are more prone to develop chemotherapy-induced SOM. Opiates have been the cornerstone of pain management for moderate to severe oral mucositis. The effective use of opiates requires balancing the desired effects of pain relief with undesired adverse effects Aim of the Work We evaluated the efficacy and safety of Nalbuphine (agonist – antagonist) in comparison with the pure agonist opioids (Morphine and Fentanyl) when used for oral mucositis pain in pediatric patients undergoing cancer therapy. Primary outcomes measures were Pain intensity self- assessment by using VAS, Number of active and total pushes of PCA buttons, Total opioid consumptions for each patient, and Patient satisfaction at the end of the 7 days using Patient Satisfaction Score PSS were assessed using a linear scale where 0 = very satisfied; 10 = very dissatisfied. Secondary outcomes measures were Adverse events including Respiratory depression, Bradycardia, Hypotension, Over sedation, Nausea and vomiting, Pruritus, Urinary retention. Patients and Methods This was a Randomized Clinical Trial conducted on 90 Pediatric patients who were diagnosed with cancer, admitted to Children Cancer Hospital -Egypt (CCHE-57357) and underwent cancer therapy that was complicated with Mucositis grade 3 and 4 (severe oral mucositis) according to the WHO scale for oral mucositis. Patients were randomly allocated into 3 equal groups each included 30 patients using of: PCA Morphine (Group M), PCA Nalbuphine (Group N) and PCA Fentanyl (Group F). Using equipotent doses of the three medications. Results Highly significant decrease in VAS score (7th day) and total opioid consumption (7th day), in Nalbuphine and Morphine groups; compared to Fentanyl group (p < 0.01 respectively). Significant increase in patient satisfaction score PSS in Nalbuphine drug group; compared to other drug groups (p = 0.032). Highly significant decrease in serious side effects (especially respiratory depression and sedation problems), in Nalbuphine and Morphine groups; compared to Fentanyl group (p = 0.0004). Conclusion Nalbuphine proven to be adequately effective, not inferior to Morphine in terms of improving pain relief, decreasing opioid consumptions in pediatric PCA users. However patients reported less satisfaction with Nalbuphine than Fentanyl or Morphine. In terms of safety profile, Nalbuphine had less adverse effects in pediatric patients with oral mucositis related to cancer therapy in comparison to Fentanyl or morphine.

Efficacy of topical agents in oral mucositis prevention: Systematic review and network meta-analysis.

Oral mucositis (OM) is considered one of the most common side effects of patients undergoing cancer therapy. OM prevention plays a crucial role in the effectiveness of cancer treatment and the patient's quality of life. Different preventive treatments have been proposed in clinical trials, however with inconclusive results. A systematic review search was conducted in PubMed, Scopus, Web of Science, and Cochrane Database to answer the PICO question: in cancer patients, do specific topical agents compared to standard treatments or placebo reduce the onset and severity of oral mucositis? The risk of bias was assessed, and a network meta-analysis was conducted. Of 2913 results, 30 randomized clinical trials were considered suitable for inclusion. A total of 2564 patients were analyzed, of which 1284 belonged to the test group and 1280 belonged to the control group. Natural products were the most used, followed mainly by antimicrobial agents, coating agents, and basic oral care measures. Topical sucralfate resulted in the most powerful intervention for the OM prevention (OR = 0.04, 95%C.I. = 0.01-0.25, p-value = 0.001). Due to its cytoprotective action, low cost, ease of administration, and safety, sucralfate could become a potential ally to prevent the onset of OM during cancer therapy.

In-hospital outcomes and mortality of drug-induced pneumonitis and radiation pneumonitis in patients with thoracic cancer.

12042 Background: Pneumonitis is one of the challenging adverse events in thoracic oncology patients undergoing cancer therapy. The cancer treatments, including targeted agents, systemic chemotherapy, immune-checkpoint inhibitors, and radiation therapy have recently advanced, however, the data on incidence of drug-induced and radiation pneumonitis (DP and RP) and their association with in-hospital outcomes is limited. Methods: Data from the National Inpatient Sample Database from 2016 to 2019 were analyzed. Adult patients with primary lung cancer were included and categorized into three groups: (1). Patients without pneumonitis, (2). Patients with DP, (3). Patients with RP. Outcomes included in-hospital mortality, intensive care unit (ICU) admission, and hospital length of stay (LOS). Data were extracted using ICD-10 codes. Results: Our analysis included 1,631,940 hospitalized primary lung cancer patients (based on a weighted sample). Among all, 4,515 patients had DP, and 16,905 patients had RP. Overall, 69.3% had smoking history, however, no significant difference between DP and RP. There was a higher prevalence of chronic obstructive pulmonary disease (COPD) in RP than DP (66.5% vs 53.2%; p<0.05) (Table). The in-hospital mortality rate was highest in DP compared to other groups. Coarsened exact matching method was used to balance covariates between non-pneumonitis and pneumonitis patients (DP and RP). Multivariate logistic regression showed that pneumonitis patients had higher odds of intubation (OR: 1.57; 95% CI: 1.24-1.99; p<0.05) and mortality (OR: 1.48; 95% CI: 1.28-1.71; p<0.05) than non-pneumonitis. Pneumonitis patients also had 23% longer length of stay than non-pneumonitis patients. We then compared the outcomes between DP and RP using the same matching algorithm, however, there was no significant difference in the outcomes between the two groups. Over the study years, the trend for DP significantly increased, whereas the RP trend was stable. Conclusions: Hospitalized pneumonitis patients had relatively poor clinical outcomes compared to patients without pneumonitis. The trend of hospitalized drug-induced pneumonitis is increasingly common. [Table: see text]

A novel Bayesian generative approach for estimating tumor dynamics from published studies.

Tumor growth inhibition (TGI) modeling attempts to describe the time course changes in tumor size for patients undergoing cancer therapy. TGI models present several advantages over traditional exposure-response models that are based explicitly on clinical end points and have become a popular tool in the pharmacometrics community. Unfortunately, the data required to fit TGI models, namely longitudinal tumor measurements, are sparse or often not available in literature or publicly accessible databases. On the contrary, common end points such as progression-free survival (PFS) and objective response rate (ORR) are directly derived from longitudinal tumor measurements and are routinely published. To this end, a Bayesian generative model relating underlying tumor dynamics to summary PFS and ORR data is introduced to learn TGI model parameters using only published summary data. The parameterized model can describe the tumor dynamics, quantify treatment effect, and account for differences in the study population. The utility of this model is shown by applying it to several published studies, and learned parameters are combined to simulate an in silico trial of a novel combination therapy in a novel setting.

Abstract 3560: Quantified kinematics and wearable sensors to predict serious adverse events in patients undergoing cancer therapy trials

Abstract Background: Serious adverse events (SAEs) are a critical determinant of drug toxicity in clinical trials. However the drivers of toxicity may be related to patient factors as much or more than drug related factors. Prior studies have shown that time in non-sedentary activity predicted toxicity in cancer patients receiving highly emetogenic chemotherapy. SAEs are a critical determinant of drug toxicity in clinical trials. However, predicting SAEs using conventional PS scales measurements, such as ECOG is challenging because measurements can vary among observers. Prior studies have used activity trackers to measure physical activity and showed that time spent in non-sedentary activity predicted toxicity in cancer patients receiving highly emetogenic chemotherapy. Here, we sought to extend these findings to early phase clinical trial participants by examining data collected in two single-arm, observational, prospective studies at USC Keck and MD Anderson centers. We explored the use of out-of-clinic wearable sensors as an objective metric of frailty so as to identify patients at risk for therapy complications. Methods: Adult patients diagnosed with cancer and enrolled in early stage clinical trials across USC Keck and MD Anderson centers were included in parallel single-arm, observational, prospective studies. Patients used a consumer grade wearable activity tracker (Fitbit) and the study examined associations between the number of severe adverse events to activity levels measured by metabolic equivalents (METs) and get-up-go times across the first 30 days. Trends were assessed using t-tests. Results: 36 eligible patients were included in METs activity analysis. There was a total of 16 recorded incidences of SAEs within the first 30 study days, with 10 patients experiencing at least one SAE. The median non-sedentary time for patients with no SAEs was 27.5 hours above 1.5 METs per week, compared to 21.5 hours for those with at least one SAE occurrence (p-value=0.0146, r2=0.1629). The median get-up-go times for those without SAEs was 10.0 seconds (n=26) and with SAEs was 9.8 seconds (n=10), (p-value=0.828, r2=0.0014). Conclusions: Non-sedentary time, as an objective measure of activity, can be used to identify those patients who are at greatest risk for SAEs in clinical trials. Widely available and inexpensive consumer grade sensors can be used as a stratification tool. Findings should be confirmed in larger patient cohorts across a wider variety of trial settings.

Interpretable machine learning-based individual analysis of acute kidney injury in immune checkpoint inhibitor therapy.

Acute kidney injury (AKI) is a critical complication of immune checkpoint inhibitor therapy. Since the etiology of AKI in patients undergoing cancer therapy varies, clarifying underlying causes in individual cases is critical for optimal cancer treatment. Although it is essential to individually analyze immune checkpoint inhibitor-treated patients for underlying pathologies for each AKI episode, these analyses have not been realized. Herein, we aimed to individually clarify the underlying causes of AKI in immune checkpoint inhibitor-treated patients using a new clustering approach with Shapley Additive exPlanations (SHAP). We developed a gradient-boosting decision tree-based machine learning model continuously predicting AKI within 7 days, using the medical records of 616 immune checkpoint inhibitor-treated patients. The temporal changes in individual predictive reasoning in AKI prediction models represented the key features contributing to each AKI prediction and clustered AKI patients based on the features with high predictive contribution quantified in time series by SHAP. We searched for common clinical backgrounds of AKI patients in each cluster, compared with annotation by three nephrologists. One hundred and twelve patients (18.2%) had at least one AKI episode. They were clustered per the key feature, and their SHAP value patterns, and the nephrologists assessed the clusters' clinical relevance. Receiver operating characteristic analysis revealed that the area under the curve was 0.880. Patients with AKI were categorized into four clusters with significant prognostic differences (p = 0.010). The leading causes of AKI for each cluster, such as hypovolemia, drug-related, and cancer cachexia, were all clinically interpretable, which conventional approaches cannot obtain. Our results suggest that the clustering method of individual predictive reasoning in machine learning models can be applied to infer clinically critical factors for developing each episode of AKI among patients with multiple AKI risk factors, such as immune checkpoint inhibitor-treated patients.

Implementation of malnutrition screening tool initiative in community cancer center for cycle 1 day 1, change in regimen, and new metastatic disease patients from Sept.–March 2022.

367 Background: Identification of patients at risk for malnutrition is imperative to provide early nutrition intervention. Patients undergoing cancer therapy are at risk for developing a variety of side effects that impact their intake, absorption, and nutritional status while undergoing antineoplastic therapy. Methods: 2021 Q4 Pilot: Implemented Malnutrition Screening Tool (MST) to identify patients at risk of malnutrition for C1D1 patients only during the Nurse Navigator visit. If the MST score is <2, but a patient requests Dietitian Counseling, a patient would be referred to the RD. If score is clinically significant, > or = 2, Nurse Navigator referred to the RD, including rationale and additional detail (i.e., amount of weight loss, poor appetite, etc.). RD reviewed all referrals related to the MST and completes further assessment and intervention if appropriate. 2022 Q4: Screening utilizing the MST was standardized during Nurse Navigator visits for all C1D1 patients, patients with new metastatic disease, patients with change in regimen and new oral therapy patients. Results: See table. Conclusions: Of the patients screened with the NCCN Distress Thermometer, 67% of those patients were identified to be screened for Malnutrition. Of the patients who were screened with the MST, ~ 26% of the patients were identified to be at risk for malnutrition. Early identification of malnutrition in treatment will result in early intervention and assessment by the dietitian to prevent poor outcomes.[Table: see text]

48 The collaboration of oncology Clinical Nurse Specialists and Public Health Nurses in comprehensive geriatric assessments in patients undergoing Cancer treatment

Abstract Background Cancer is a widespread health issue, with the number of people >70 diagnosed in 2020, reaching 7.2 million (37% of all cases) worldwide. This is expected to double by 2040. Valid and reliable tools to assess older patients undergoing cancer therapy are necessary to reduce toxicities, decrease delays, and better guide dose modifications. There are performance assessment tools used in oncology, however, they are subjective and have limited use for toxicity risk stratification. Currently, patients do not routinely have a frailty assessment in the oncology setting. Public Health Nurses (PHN) often know these individuals before commencing treatment, they may have a therapeutic relationship with the patient and family, and are in a prime position to perform a frailty assessment which can detect vulnerabilities and age related issues associated with mortality. Moreover, collaboration between Acute services and primary care may enhance CGA’s and improve patient care. Methods Two case studies are examined, where collaboration of Acute services and Primary care improved patient outcomes and quality of life. Results Case study 1: PHN identified early toxicities of treatment, Rockwood Scale used, Liaised with acute oncology CNS (Clinical Nurse Specialist) and dose of treatment modified, resulting in completion of treatment and avoidance of unnecessary hospital admissions. Case study 2: CNS contacted PHN as concerned about patient on treatment, G8 frailty score: 7 (very vulnerable). PHN supported a Comprehensive Geriatric Assessment (CGA). On discussion with Oncology team, treatment modified, and supports such as OT, Dietician and Physiotherapy were added. Conclusion Recommendations for practice include a role for combined Geriatric Oncology services, and also the use of in depth assessment tools in older patients to prevent treatment related toxicity. Collaboration of acute oncology and primary care teams may help identify earlier the need for CGA and enhance integration of care pathways.

Right ventricle toxicity in cancer treatment: a focused review on cardiac imaging.

Background: The right ventricle (RV) remains the 'forgotten chamber' in the clinical assessment of cancer therapy-related cardiac dysfunction (CTRCD). Aim: We aimed to review the role that various cardiac imaging modalities play in RV assessment as part of the integrative management of patients undergoing cancer therapy. Discussion: RV assessment remains challenging by traditional 2D echocardiography. In this review we discuss other parameters such as right atrial strain, and other echocardiographic modalities such as 3D and stress echocardiography. We also elaborate on the specific role that cardiac magnetic resonance imaging and equilibrium radionuclide angiocardiography can play in assessing the RV. Conclusion: Biventricular function should be monitored following chemotherapy for early detection of subclinical CTRCD and possible solitary RV changes.

Human oral mucosa and oral microbiome interactions following supragingival plaque reconstitution in healthy volunteers: a diet-controlled balanced design proof-of-concept model to investigate oral pathologies

ABSTRACT Changes in the oral microbiome may contribute to oral pathologies, especially in patients undergoing cancer therapy. Interactions between oral microbiome and oral mucosa may exacerbate inflammation. We determined whether probiotic-controlled plaque formation could impact proximal oral mucosa gene expression profiles in healthy volunteers. A 3-weeks balanced sample collection design from healthy volunteers (HVs) was implemented. At Week-1 plaques samples and labial mucosa brush biopsies were obtained from HVs in the morning (N = 4) and/or in the afternoon (N = 4), and groups were flipped at Week-3. A fruit yogurt and tea diet were given 2-4hrs before sample collection. mRNA gene expression analysis was completed using RNA-Seq and DESeq2. Bacterial taxa relative abundance was determined by 16S HOMINGS. Bacterial diversity changes and metabolic pathway enrichment were determined using PRIMERv7 and LEfSe programs. Alpha- and beta-diversities did not differ morning (AM) vs. afternoon (PM). The most affected KEGG pathway was Toll-like receptor signaling in oral mucosa. Eighteen human genes and nine bacterial genes were differentially expressed in plaque samples. Increased activity for ‘caries-free’ health-associated calcifying Corynebacterium matruchotii and reduced activity for Aggregatibacter aphrophilus, an opportunistic pathogen, were observed. Microbial diversity was not altered after 8 hours plaque formation in healthy individuals as opposed to gene expression.

Study of usefulness of speckle-tracking echocardiography in detecting left ventricular dysfunction among adult cancer patients undergoing chemotherapy

Objective: Cancer treatment-related cardiac dysfunction (CTRCD) is a significant concern for patients undergoing chemotherapy. The aim of the present study was to study the accuracy and value of longitudinal strain in prediction of left ventricular dysfunction (LVD) in cancer patients undergoing cancer therapy. Methods: This was a prospective observational study conducted among 183 adult patients undergoing chemotherapy between 2018 and 2020. Patients with congenital or acquired valvular disease, prior myocardial infarction, coronary revascularization, or cardiac surgery were excluded. The patients were evaluated using a detailed history, clinical examination and echocardiography at baseline, 1 month, 3 months, and 6 months after chemotherapy. Speckle-tracking strain analysis was used to evaluate left ventricular (LV) global longitudinal strain (GLS), circumferential strain (GCS), and radial strain (GRS). LVD was defined as &qt;15% decrease in GLS, GCS, or GRS from baseline to 6 months. Accuracy of longitudinal strain in prediction of LVD was studied using ROC analysis. Results: Of the 183 patients, 59% were male, and 54.1% were between 46-60 years of age. Breast cancer was the most common malignancy (10.9%). The most common chemotherapy regimen was doxorubicin + paclitaxel (9.9%). At baseline, the mean GLS, GCS, and GRS were -18.6 (1.03)%, -20.4 (1.11)%, and 39.9 (6.09)%, respectively. At the 6-month follow-up, 27 (14.8%) patients had LVD. The incidence of LVD was higher (51.48%) in patients who received doxorubicin-containing regimens compared to non-doxorubicin-containing regimens (P <0.0001). GLS has good accuracy in prediction of LVD at 6 months of follow-up (88.37%). Conclusions: The incidence of LV dysfunction was higher (51.48%) in patients who received doxorubicin-containing regimens. GLS is different in LVD vs non LVD and the accuracy of GLS is more in prediction of LVD development during 6-month follow-up (88.37%).

Closing the cancer care gap with a patient-reported nutrition screening: A retrospective analysis of a quality improvement project on an oncology ward (CCC study)

Early identification of patients at risk for malnutrition followed by individualized nutrition interventions is a central step to the provision of appropriate nutrition care. However, a health care professional (HCP)-based nutrition screening is not always consistently integrated into routine care. Patient-reported (PR) nutrition screening could thus potentially alleviate the burden on the HCPs and contribute to a greater number of patients who are identified and treated for malnutrition. In 2021 a Quality Improvement Project (QIP) at our out-patient oncology clinic was undertaken to implement the change from a HCP-based nutrition screening to a PR-screening. This was followed by a retrospective analysis in which the primary outcome measure was the rate of nutrition consultations initiated for patients undergoing cancer therapy. In total n=1657 patient data sets derived from comparable time periods before and after the QIP were analyzed and compared. Both groups had a comparable mean age and gender distribution. The most common diagnosis in both groups was gastrointestinal tumors. The change in routine care from a HCP-based nutrition screening to a PR-screening led to a significant increase in nutrition consultation rates (RD=19%; p<0.001; 95% CI 14.4%-23.5%) and screening rates (RD =30.5%; p <0.001; 95% CI 26.2%-34.7%). The change to PR-screening potentially facilitates an increase in nutrition screening rates. This in turn leads to an increased rate of patients identified at risk for malnutrition and thus referrals for nutrition consultations. Our findings indicate that a PR nutrition screening tool could play a role in closing the care gap and contribute to reducing rates of malnutrition among this population where screening is not consistently integrated into routine care.

Prevalence of cancer therapy cardiotoxicity as assessed by imaging procedures: A scoping review.

Advances in treatment and optimization of chemotherapy protocols have greatly improved survival in cancer patients. Unfortunately, treatment can cause a reduction in left ventricular (LV) ejection fraction (EF) leading to cancer therapy-related cardiac dysfunction (CTRCD). We conducted a scoping review of published literature in order to identify and summarize the reported prevalence of cardiotoxicity evaluated by noninvasive imaging procedures in a wide-ranging of patients referred to cancer treatment as chemotherapy and/or radiation therapy. Different databases were checked (PubMed, Embase, and Web of Science) to identify studies published from January 2000 to June 2021. Articles were included if they reported data on LVEF evaluation in oncological patients treated with chemotherapeutic agents and/or radiotherapy, measured by echocardiography and/or nuclear or cardiac magnetic resonance imaging test, providing criteria of CTRCD evaluation such as the specific threshold for LVEF decrease. From 963 citations identified, 46 articles, comprising 6841 patients, met the criteria for the inclusion in the scoping review. The summary prevalence of CTRCD as assessed by imaging procedures in the studies reviewed was 17% (95% confidence interval, 14-20). The results of our scoping review endorse the recommendations regarding imaging modalities to ensure identification of cardiotoxicity in patients undergoing cancer therapies. However, to improve patient management, more homogeneous CTRCD evaluation studies are required, reporting a detailed clinical assessment of the patient before, during and after treatment.

A hospital-based oral health education program impacts in pediatric cancer patients-A pilot study.

To assess the impact of an oral health education and preventive program (OHEPP) for pediatric cancer patients. This was a single-arm study with 27 children and adolescents undergoing antineoplastic treatments. Patients were followed up for 10 weeks, and their oral health conditions were evaluated using the Modified Gingival Index (MGI), Visible Plaque Index (VPI), and the modified Oral Assessment Guide (OAG). Audiovisual resources, storytelling, and ludic instruments were used to provide oral health education to patients and parents/caregivers. The patients' mean age was 9.41(±4.49) years, and acute lymphoblastic leukemia was the most prevalent diagnosis (22.2%). Mean MGI and VPI values were 0.82(±0.59) and 54.11%(±19.92%) at baseline and 0.33 (±0.29) and 19.83% (±11.47%) after 10weeks, respectively (p<.05). The mean OAG score was 9.51 (±2.54) and 36 cases (19.8%) of severe oral mucositis (SOM) were documented. Patients with higher MGI were more likely to develop SOM. The OHEPP had a positive impact on pediatric patients undergoing cancer therapy by improving their periodontal health, reducing biofilm accumulation, and preventing the development of OM lesions.

Presence of cachexia in the treatment phase of head and neck cancer: a chronic nutritional condition in patients undergoing cancer therapy.

Oral health in older adults with cancer

Cancer is a disease of older adults, with 60% of cancer diagnoses and 70% of cancer deaths occurring in individuals ≥ 65 years. Normal oral aging may transition to disease in the presence of one or more potential modifiers, such as a new oncological diagnosis or a new treatment. Oral conditions in patients with cancer cause significant morbidity. Previous work suggests that oral conditions are neither elicited/assessed/reassessed nor well-managed or investigated in older patients. However, frequently reported oral conditions in patients undergoing cancer therapy include xerostomia, dysgeusia, candidiasis, mucositis, and dental caries. Some oncological treatments such as hematopoietic stem cell transplant or chemotherapy/radiotherapy for head and neck cancers entail higher risks of oral complications. No specific recommendations in the case of older adults with cancer-associated oral conditions are available. Treatment recommendations are based on low levels of evidence and/or evidence extrapolated from younger patients with câncer.

Cancer-therapy-induced mucosal injury from 2001 to 2021: A bibliometric analysis.

Cancer-therapy-induced mucosal injury (CMI) is a common and deleterious complication that affects patients undergoing cancer therapies. This study was aimed at elucidating knowledge bases and predicting research trends of this field, by analyzing the bibliographic data of CMI. The bibliographic data of CMI from 2001 to 2021 were extracted from the Web of Science Core Collection database in March 2022. After screening, a total of 8181 articles and reviews were included in the study. CiteSpace and VOSviewer were applied to analyze and visualize cooperation, cooccurrence, cocitation, and coupling networks. A steady increase in publications and a burst of citation since 2019 were seen in the subject. Supportive Care in Cancer, International Journal of Radiation Oncology Biology Physics, Annals of Oncology, Cancer, and Radiotherapy and Oncology were the most influential journals of this field. The University of Adelaide, University of Texas MD Anderson Cancer Center, and Memorial Sloan Kettering Cancer Center were the top three most productive institutions. ST Sonis, RV Lalla, JB Epstein, and DMK Keefe were the authors with impressive publications and citations. The intellectual base was the publication network of improved treatments based on updating knowledge of CMI. The future trends would be the pathogenesis of CMI, mechanism-based interventions, microbiota of oral and gastrointestinal mucosa, and photobiomodulation. This study introduced the evolving publication network and predicted the research trends of CMI, which helped researchers to obtain detailed and reliable knowledge of the discipline, and focus on the most urgent unsolved problems in this field.

Pulmonary function tests, fatigue levels and functional capacity in head and neck cancer patients undergoing cancer therapy

BACKGROUND: The changes in pulmonary functions and fatigue; occurring in the months and years following cancer therapy have been well documented. The changes that occur in the hours of the cancer treatment are less clear. AIMS AND OBJECTIVES: The changes detected in the early stage of cancer treatment may help to prevent late pulmonary &amp; associated complications. MATERIALS AND METHODS: The pre and post scores were taken after 3 days of treatment. PFT was recorded by vitalograph &amp; peak flow meter, fatigue levels were assessed by FACIT-F scale and functional capacity was assessed by distance covered in 6- minute walk test. RESULTS: One hundred and seventeen patients with head and neck cancer were recruited 108 were males and 09 females with mean age of 52.2 years; there is a significant statistical reliable difference between the pre &amp; post treatment values, with P-value is 0.001&lt; 0.05. It justifies the deuteriations in health outcome post intervention. CONCLUSION: There is significant deterioration seen in the PFT, fatigue levels, functional capacity; could cause significant clinical problems. Early detection of all these changes can helps the patients as well as therapist to avoid or minimal late complications.

Interprofessional Collaboration Among Dental Hygiene and Nursing Students on the Oral Health of Cancer Patients.

One third of patients diagnosed with cancer develop oral complications during cancer treatment. Health care professionals play an important role in the management of patients undergoing cancer therapies; however, optimal oral care for cancer patients is often missing from nursing and dental hygiene curricula. A quasi-experimental mixed-methods study was conducted with accelerated bachelor of nursing and dental hygiene students following a presentation and small-group case review. Pre/post surveys and findings from a debriefing session showed increased confidence to screen, counsel, and refer patients between disciplines compared to a control group.
