Feasibility of an MR-based digital specimen for tongue cancer resection specimens: a novel approach for margin evaluation. Front Oncol 2024; 14:1342857. [PMID: 38606095 PMCID: PMC11007136 DOI: 10.3389/fonc.2024.1342857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Accepted: 03/15/2024] [Indexed: 04/13/2024] Open
Abstract
Objective This study explores the feasibility of ex-vivo high-field magnetic resonance (MR) imaging to create digital a three-dimensional (3D) representations of tongue cancer specimens, referred to as the "MR-based digital specimen" (MR-DS). The aim was to create a method to assist surgeons in identifying and localizing inadequate resection margins during surgery, a critical factor in achieving locoregional control. Methods Fresh resection specimens of nine tongue cancer patients were imaged in a 7 Tesla small-bore MR, using a high-resolution multislice and 3D T2-weighted Turbo Spin Echo. Two independent radiologists (R1 and R2) outlined the tumor and mucosa on the MR-images whereafter the outlines were configured to an MR-DS. A color map was projected on the MR-DS, mapping the inadequate margins according to R1 and R2. We compared the hematoxylin-eosin-based digital specimen (HE-DS), which is a histopathological 3D representation derived from HE stained sections, with its corresponding MR-images. In line with conventional histopathological assessment, all digital specimens were divided into five anatomical regions (anterior, posterior, craniomedial, caudolateral and deep central). Over- and underestimation 95th-percentile Hausdorff-distances were calculated between the radiologist- and histopathologist-determined tumor outlines. The MR-DS' diagnostic accuracy for inadequate margin detection (i.e. sensitivity and specificity) was determined in two ways: with conventional histopathology and HE-DS as reference. Results Using conventional histopathology as a reference, R1 achieved 77% sensitivity and 50% specificity, while R2 achieved 65% sensitivity and 57% specificity. When referencing to the HE-DS, R1 achieved 94% sensitivity and 61% specificity, while R2 achieved 88% sensitivity and 71% specificity. Range of over- and underestimation 95HD was 0.9 mm - 11.8 mm and 0.0 mm - 5.3 mm, respectively. Conclusion This proof of concept for volumetric assessment of resection margins using MR-DSs, demonstrates promising potential for further development. Overall, sensitivity is higher than specificity for inadequate margin detection, because of the radiologist's tendency to overestimate tumor size.

Abstract
Today, both Ukraine and the world at large are faced with a significant number of oncological diseases with various localizations. The current state of diagnosis, prevention, early detection, and access to treatment leads to a substantial number of people in each country's healthcare system who require comprehensive cancer treatments. Modern medical and diagnosis protocols in oncology involve the usage of ionizing radiation and aggressive toxic chemotherapeutic agents which can significantly disrupt the physiology of the mucous membrane of the digestive tract during treatment, especially of the oral cavity. The most common complication of complex anticancer therapy is the development of various lesions of the oral cavity, including mucositis, which harms the patient's quality of life, limits the doses of chemotherapy and radiation therapy the patient can receive, and also negatively affects the effectiveness of complex therapy treatment. Acute oral mucositis is observed among almost 100% of treatment cases. This is a significant problem for clinical oncology as it may also reduce patient compliance with comprehensive anticancer treatment. The results indicate the presence of oral problems in 100% of patients receiving specialized antitumor chemotherapy and radiotherapy, as well as the presence of a high need for specialized dental treatment.

Abstract
Objectives: This study aims to investigate the factors that lead to poor compliance in initiating the treatment in patients with newly diagnosed head and neck cancers. Methods: A total of 193 patients from the head and neck cancer database dated from January 1, 2018 to September 30, 2020, were analyzed. Variables analyzed included age, gender, primary cancer site, T stage, N stage, M stage, overall stage (I-IV), patient's residential distance, and the impact of COVID-19. Univariate and multivariate analyses were used to assess the significance of these variables in relation to the time to receiving on-time treatment as recommended by specialists. Results: Upon multivariate analysis, the advanced stage and residential distance were significantly associated with initial compliance (P < .09). The impact of nasopharyngeal carcinoma (NPC) and COVID-19 shows a borderline significance (P = .224 and P = .184). Conclusions: The overall stage and patient living distance to the healthcare facility, patient with NPC, and the impact of COVID-19 might affect the compliance of initiating a curative-intent treatment in patients with newly diagnosed head and neck cancers.

Abstract
OBJECTIVE Anxiety and depression are frequent conditions among individuals undergoing antineoplastic therapy, but their relationship with oral mucositis is unclear. This systematic review evaluated the potential association of anxiety and depression with frequency and severity of chemo/radiotherapy-induced oral mucositis. MATERIALS AND METHODS Electronic searches were undertaken in five databases supplemented by manual scrutiny and gray literature searches in three other databases. The risk of bias was assessed using the Joanna Briggs Institute tool. RESULTS Eight observational studies conducted on 954 individuals (male-to-female ratio: 1.1:1; age range: six-82 years). Three (37.5%) studies included patients with solid tumors, two (25%) studies included hematopoietic/lymphoid tissue tumors, and two (25%) studies comprised mixed types of malignant neoplasms. Eight different instruments were used to assess oral mucositis, while seven different instruments were used to evaluate anxiety and depression. Associations of anxiety and/or depression with oral mucositis severity were reported in six (75.0%) studies. Oral mucositis-related symptoms, especially pain, were linked with depression in three (37.5%) studies. CONCLUSION A relatively low number of cases and data heterogeneity hamper definitive conclusion about the potential association between anxiety/depression and oral mucositis. Further studies that could guide more personalized treatments are warranted to investigate this plausible bidirectional interaction.

Abstract
Objective: To systematically summarize the evidence for photobiomodulation therapy (PBMT) in the prevention and treatment of oral mucositis (OM) in patients undergoing cancer treatment. An electronic search was conducted in 8 databases and grey literature. Background: PBMT is recommended for the management of OM resulting from cancer treatment, with several systematic reviews (SRs) being published in recent years on this topic. Methods: Only SRs with outcomes from clinical trials were included, with no language or year restriction. The AMSTAR 2 tool was used to assess the methodological quality of the SRs. Results: Five thousand eight hundred fifty-six references were found, and 16 were selected for this review. OM prevention and treatment were favorable for PBMT in most studies, with a significant reduction in OM severity. Most studies obtained moderate confidence. Conclusions: PBMT represents an effective strategy in the management of OM, and this evidence is supported by studies with acceptable methodological quality.

Abstract
Head and neck cancers (HNCs) have a profound impact on patients, affecting not only their physical appearance but also fundamental aspects of their daily lives. This bibliometric study examines the landscape of scientific research pertaining to the quality of life (QoL) among head and neck cancer (HNC) patients. By employing data and bibliometric analysis derived from the Web of Science Core Collection (WOS-CC) and employing R-package and VOSviewer for visualization, the study assesses the current status of and prominent areas of focus within the literature over the past decade. The analysis reveals noteworthy countries, journals, and institutions that have exhibited notable productivity in this research domain between 2013 and 2022. Notably, the United States, the Supportive Care in Cancer journal, and the University of Pittsburgh emerged as the leading contributors. Moreover, there was a discernible shift, with an increasing focus on the significance of QoL within the survivorship context, exemplified by the emergence and subsequent peak of related keywords in 2020 and the subsequent year, respectively. The temporal analysis additionally reveals a transition towards specific QoL indices, such as dysphagia and oral mucositis. Therefore, the increasing relevance of survivorship further underscores the need for studies that address the associated concerns and challenges faced by patients.

Abstract
Objectives After resection of an oral carcinoma, patients are faced with physical, psychological, and socioeconomic challenges. Rehabilitation plays an essential role in patients' reintegration into their social and professional environment. This study evaluated whether socioeconomic aspects affect oral cancer patients' participation in rehabilitation treatment. Materials and methods A retrospective analysis was conducted with 1,532 patients following surgical treatment of oral cancer during an international multicenter rehabilitation study of the German-Swiss-Austrian Cooperative Working Group on Maxillofacial Tumors using a questionnaire comprising disease-related and psychosocial items postoperatively and at least 6 months after surgery. Results Only 35.4% of patients participated in rehabilitation. Age (p<0.001), sex (p<0.001), and marital status (p<0.05) significantly influenced participation in rehabilitation. Postoperative impairment (p<0.05) as well as quality of life (p<0.01) were significantly worse in patients who participated in rehabilitation. Nevertheless, this group of patients returned to work significantly more often, although later, than those who did not participate in rehabilitation (p<0.05). Conclusions The findings show social inequalities and suggest a general undersupply of rehabilitative follow-up treatment in patients with oral cancer. More patients, especially older people and women should be referred to rehabilitation.

Abstract
OBJECTIVES Surgical removal of squamous cell carcinoma of the tongue (SCCT) with tumour-free margin status (≥5 mm) is essential for loco-regional control. Inadequate margins (<5 mm) often indicate adjuvant treatment, which results in increased morbidity. Ultrasound (US)-guided SCCT resection may be a useful technique to achieve more adequate resection margins compared to conventional surgery. This study evaluates the application and accuracy of this technique. METHODS Forty patients with SCCT were included in a consecutive US cohort. During surgery, the surgeon aimed for a 10-mm echographic resection margin, while the tumour border and resection plane were captured in one image. Ex-vivo US measurements of the resection specimen determined whether there was a need for an immediate re-resection. The margin status and the administration of adjuvant treatment were compared those of with a consecutive cohort of 96 tongue cancer patients who had undergone conventional surgery. A receiver operating characteristic analysis was done to assess the optimal margin of ex-vivo US measurements to detect histopathologically inadequate margins. RESULTS In the US cohort, the frequency of free margin status was higher than in the conventional cohort (55% vs. 16%, p < 0.001), and the frequency of positive margins status (<1 mm) was lower (5% vs. 15%, respectively, p < 0.001). Adjuvant radiotherapy was halved (10% vs. 21%), and the need for re-resection was comparable (10% vs. 9%). A cut-off value of 8 mm for ex-vivo measurements prevented histopathologically inadequate margins in 76%. CONCLUSION US-guided SCCT resections improve margin status and reduce the frequency of adjuvant radiotherapy.

Abstract
ObjectiveIn many countries the access to high quality medical service depends on socioeconomic factors. Therefore, these factors are associated with the treatment and prognosis of many diseases. In Germany health care is claimed to be independent from such factors due to obligatory health insurance and a well-developed medical infrastructure. Thus, socioeconomically caused health disparities should be absent. The aim of this study was to analyze the association between socioeconomic factors and the survival of oral cavity cancer in Germany.Patients and methodsIn this descriptive cohort study socioeconomic status related factors as well as demographic, tumor-specific, and comorbidity factors of 500 patients treated for oral cavity cancer were obtained in the university hospital of Dresden. Pearson correlation was used to describe associations between continuous variables. Associations between categorical variables were assessed using the chi-square test. Overall and recurrence-free survival were studied using the Kaplan-Meier method. Log-rank test was carried out to test between-group differences. Cox proportional hazard models were used to estimate the risk of death and the risk of recurrence.ResultsSignificant differences in overall survival were found between the different educational levels and sex. Seventy-nine percent of the patients did not have a university degree or master craftsman/craftswoman. Less discrepancy was observed according to the marital status (49.4% married/engaged vs. 47.8% single, divorced, or widowed). In the multivariable analysis only sex, age at diagnosis, the Charlson score, the number of positive lymph nodes, and the nodal status were identified as independent predictors for overall survival whereas sex and the age at diagnosis were identified as independent predictors for recurrence-free survival.ConclusionDespite the equitable health system in Germany, significant associations between overall survival of oral cavity cancer and different socioeconomic factors could be found. For elimination of these disparities, health education programs should be established in socially deprived areas. Furthermore, clinicians should keep these factors in mind when determining recall periods for dental check-ups.

Abstract
BACKGROUND There is a need for studies that correlate the severity of oral mucositis (OM) with chemotherapy protocols, transient myelosuppression and oral health. OBJECTIVE To analyze the severity of OM among individuals with solid tumors during hospitalization and its correlation with the type of chemotherapy, myelosuppression and oral health condition. DESIGN AND SETTING Retrospective study at a public hospital in Bauru, state of São Paulo, Brazil, that is a regional referral center. METHODS Individuals diagnosed with solid malignant tumors who received chemotherapy during hospitalization for completion of the antineoplastic treatment cycle or who presented complications resulting from this were assessed. RESULTS Twenty-eight individuals (24.3%) manifested some degree of OM. The most prevalent degrees of OM according to the World Health Organization (WHO) and modified WHO classification were grades 2 (11.3%) and 5 (4.3%), respectively. It was observed that the higher the OM-WHO (P < 0.001; r = 0.306) and modified OM-WHO (P < 0.001; r = 0.295) classifications were, the greater the oral pain reported by the individuals was. Presence of mucositis in the upper lip and buccal mucosa contributed to increased severity of OM and worsening of swallowing during hospitalization. Thus, severe OM was associated with use of the FOLFIRI protocol (folinic acid, fluorouracil and irinotecan). CONCLUSION Individuals with tumors who presented severe OM had greater severity of oral pain and worse oral health. Use of the FOLFIRI protocol was associated with higher prevalence of severe OM, while use of 5-fluorouracil (5-FU) was correlated with worse oral condition.

Abstract
OBJECTIVE This ex vivo study evaluated the effects of different fixed dental prostheses and protective materials on scattered radiation during radiation therapy (RT). STUDY DESIGN Natural teeth (group NT) and 4 types of prostheses (group BL: bilayer lithium disilicate glass-ceramic; group MZ: monolithic zirconia ceramic; group BZ: bilayer zirconia-based all ceramic; and group BM: bilayer metal-ceramic restorations) were examined in maxillary and mandibular arch phantoms. All groups were divided into 3 subgroups: (1) without protective material over the prostheses; (2) protected with a soft acrylic night guard; and (3) protected with polyvinylsiloxane putty. All groups were irradiated with helical RT at 2 Gy and 6 MV photon energy. Doses were measured internally and externally 3 times on each phantom. Results were significant at P < .05. RESULTS No statistically significant differences in doses were found between groups NT and BL in either phantom, but these groups were different from the others. The differences between groups BZ and MZ were insignificant. Doses in group BM were significantly larger than all other groups. No significant differences existed between doses with and without protective material. CONCLUSIONS Doses increased significantly due to scattered radiation from the prostheses with increasing material density. Protective materials had no significant effect on dose.

Abstract
BACKGROUND: Oral mucositis is one of the complications in patients undergoing cancer therapy. Oral cryotherapy (OC) is an intervention to reduce the severity of oral mucositis.
AIM: To identify, analyze, and evaluate articles regarding the effectiveness of cryotherapy for oral mucositis in cancer patients undergoing cancer therapy.
METHODS: We performed searching on seven databases (PubMed, CENTRAL, Wiley, CANCERLIT, Science Direct, EBSCO, and SpringerLink). The investigation focused on English-language articles, intervention, or observational study reporting on the effectiveness of OC against oral mucositis in patients undergoing chemotherapy, and published between October 2015 and October 2020.
RESULTS: Eleven articles met the eligibility criteria for inclusion consisting of 5 RCTs, 3 Quasi-Experiment studies, 2 Cohort studies, and one pre-experimental study. The majority of the studies show that OC is an effective intervention to reduce the degree and severity of oral mucositis in patients undergoing cancer therapy (Hematopoietic Stem Cell Transplantation and chemotherapy).
CONCLUSION: OC is practical, low-cost, and relatively safe and can be an alternative therapy in reducing oral mucositis as a side effect of cancer therapy.

Abstract
PURPOSE Oral cancer resection can cause physical and psychological impairments that influence the quality of life (QoL). Depending on the postoperative time-distance, the occurrence and intensity of these impairments may change. We evaluated the sequelae and changes in therapy-related impairments during the postoperative course to detect associations between the time since surgery and the presence of disorders. METHODS Data from a questionnaire completed by 1359 patients who underwent surgical treatment of oral squamous cell carcinoma and were involved in a multicenter rehabilitation study of the German-Austrian-Swiss Cooperative Group on Tumors of the Maxillofacial Region (DÖSAK) that included 43 oral and maxillofacial clinics in Germany, Austria, and Switzerland were retrospectively analyzed. RESULTS Physical impairments, including those in appearance, mouth opening ability, ability to smell, gastric disorders, mandible mobility, breathing, and shoulder/arm mobility, were significantly associated with and increased with time-distance since surgery. Esthetic appearance most strongly correlated with the highest perception of worsening. Regarding psychological disorders, worry about tumor recurrence, depression, and worse prospects were significantly associated. Among the postoperative sequelae, fear of tumor recurrence decreased continuously; however, depression and worse prospects increased. The general QoL did not significantly differ overall during the postoperative course. CONCLUSIONS Therapy-related impairments change during the postoperative course based on the time-distance since surgery. The general QoL may not markedly vary; however, single impairments, to some extent, can increase or decrease. IMPLICATIONS FOR CANCER SURVIVORS Continuous adaptation of supportive cancer therapy is required during follow-up to sufficiently address individual treatment needs.

Abstract
Patient-reported outcomes (PRO) are an important component of treatment evaluation. Typically they are completed by patients on paper, but through advances in technology such as mobile phone apps and websites, there is a great opportunity for electronic completion. It can be challenging, particularly at a regional or national level, to maintain accurate core clinical records on head and neck cancer (HNC) (baseline, recurrence, second primary, and further treatment), and these will influence PROs and the reporting of outcomes. In addition, with data security and confidentiality there is merit in undertaking anonymous surveys, but in this approach, there is a reliance on patients' recall. The aim of this study therefore was to compare updated hospital records with details completed by patients. In January 2019, 395 HNC patients who had been treated in 2015 and 2016 were sent a survey. They were asked to recall the clinical variables of gender, age at diagnosis, tumour site, tumour stage, and primary treatment, and these were analysed for agreement with the hospital records. The kappa statistic (KP) was used to measure the strength of agreement for categorical variables. There were 146 responders and one patient correctly stated that they did not have cancer. Five indicated further disease rather than primary cancer. Agreement between the hospital record and patients' recall was excellent for gender (KP=0.97) and age group (KP=0.92), very good for treatment (KP=0.79), and good for site of cancer (KP=0.61), but poor for stage of cancer (KP=0.18). In general, patients gave accurate accounts of these details apart from tumour stage.

Abstract
BACKGROUND Tumorous diseases of the head and neck region annually occur in more than 550.000 cases worldwide. Little is known about patient specific care needs and potential relationships between non-fulfillment of those following therapeutic and especially surgical treatment of head and neck cancer (HNC). OBJECTIVES This study aimed to evaluate potential correlations between patient specific care needs, regarding physiological rehabilitation, family/social support, economic needs, and their impact on health-related quality of life (HRQoL). METHODS A total of 1359 patients were included in this retrospective analysis. Data derived from the exploratory international multicenter rehabilitation study of the German-Austrian-Swiss Cooperative Group on Tumors of the Maxillofacial Region (DÖSAK), including 43 oral and maxillofacial departments in Germany, Austria, and Switzerland using the Bochum patient questionnaire on rehabilitation and a questionnaire on tumor and treatment related data. RESULTS Results showed a significant correlation of a patient's social bonds and depression, coping with depression, and anxiety. Patients' needs for speech therapy, physiotherapy or respiratory training were hardly ever met and patients had to compensate for financial losses during hospitalization for acute treatment. CONCLUSION In conclusion, this study describes social, physical, and socio-economic care needs. A multidisciplinary approach managing cancer and treatment related side effects is necessary, as well as enhanced awareness of care needs of practitioners during early recovery after surgery.

Abstract
OBJECTIVE Quality of life in cancer patients has become an important outcome measure. This study aimed to translate and validate the European Cancer Research and Treatment Core Quality of Life Questionnaire (EORTC QLQ-C30) in Azerbaijan. METHODS Forward-backward procedure was applied to translate the EORTC QLQ-C30 from English into Azeri. Then a cross sectional study was conducted to validate the questionnaire in Azerbaijan. A sample of patients with confirmed diagnosis of oral cancer completed the Azeri version of the questionnaire from January 2017 to December 2018. Construct validity was assessed by performing know groups comparison and item-scale correlation matrix. Reliability was examined by estimating the Cronbach's alpha coefficient for internal consistency. RESULTS In all 141 patients with oral cancer participated in the study. Known groups comparison indicated that the Azeri version of EORTC QLQ-C30 well differentiated between patients who differed in the disease stage. Those with higher stage reported lower functioning and higher symptoms. In addition item-scale correlation matrix showed a good correlation between items and its own hypothesized subscales as expected (Pearson correlation coefficient ranging from 0.735-0.978). The Cronbach's alpha coefficient ranged form 0.68 to 0.94 indicating acceptable results for the internal consistency of the questionnaire. CONCLUSION This preliminary validation study proved that the Azeri version of EORTC QLQ-C30 is a valid measure of quality of life in cancer patients. However, studies with other cancer patients and stronger psychometric evaluations are recommended.
