The oral problems of 24 cancer patients on immunotherapy between 2017–2022 and referred by their oncologists, were reported. The age range was 49–80 years, and the median was 64 years. Lung cancer was the most common disease. Three patients a had history of autoimmune disease prior to cancer diagnosis. Patients received immunotherapy for two to 48 months. Prior to immunotherapy, 17 patients received cytotoxic chemotherapy, five angiogenesis inhibitors and one1 radiotherapy to head/neck. During immunotherapy, four patients received chemotherapy, one received bevacizumab, and eight received bone targeting agents, either alone or in combination. Presenting symptoms were oral pain (18 patients, 75%), dental pain (five patients), xerostomia (five patients), burning/itching (seven patients), bleeding (three patients), swelling (three patients), and taste problems (dysgeusia) (three patients). One patient was asymptomatic. Immune-related lesions were observed in 15 patients (62.50%), of which three were exacerbations of prior autoimmune disease. Three patients reported severe deterioration and itching after using a mouthwash. We also observed six (25%) infections (four candidiasis and two herpes simplex), and six (25.00%) cases of medication-related osteonecrosis of the jaw (MRONJ). Five of those MRONJ cases developed among the eight patients with the administration of bone targeting agents and one in a patient with bevacizumab. Two patients presented with more than one lesion. In conclusion, immune-related lesions were most common; oral infections and MRONJ were also observed. Various oral complications might be related to the interplay between immunotherapy and other therapies prior or concurrent to immunotherapy.

Medication-Related Osteonecrosis of the Jaw (MRONJ) is defined as a complication, which affects the jawbone of patients that meet all of the following criteria: (a) patients were in the past or are now on treatment with bone targeting agents (BTAs) and/or antiangiogenics, (b) they have exposed bone or bone that can be probed through an intraoral or extraoral fistula for more than 8 weeks, and (c) they have no history of radiotherapy or obvious metastatic disease to the jaws. Since the first reports, in 2003, plethora of articles on MRONJ significantly increased our knowledge of this potentially serious complication. However, controversies about the definition and clinical presentation, risk factors, radiological findings, staging and early diagnosis, prevention and treatment may affect the successful management and the quality of life of cancer patients. The purpose of this article is to present the current knowledge about MRONJ and the recent advances to best clinical practice and treatment. Important questions will be discussed, including the following: (1) Should we wait for 8 weeks when a patient on antiresorptive therapy, presents with exposed necrotic jawbone? (2) Can we exclude the diagnosis of osteonecrosis if a patient presents without exposed bone? (3) Is the dental extraction a risk factor for MRONJ? (4) Should we perform the dental extraction, when a patient on antiresorptives, presents with a symptomatic tooth? (5) What is the role of dental or periodontal infection? (6) Shall we re-start the antiresorptives following healing of previous MRONJ?

Objectives: To prospectively evaluate the imaging characteristics of Medication-Related Osteonecrosis of the Jaw (MRONJ), observed in the Orthopantomogram (OPG) and in Cone Beam Computed Tomography (CBCT), in patients with cancer. Materials and Methods: Cancer patients, who received Bone Targeting Agents (BTAs) and developed MRONJ, were prospectively included in the study. MRONJ was staged following the American Association of Oral and Maxillofacial Surgery (AAOMS) 2014 criteria. Four predefined radiological findings, osteolytic changes, sclerosis, periosteal reaction, and sequestration were assessed and were scored as “absent”, “localized”, “extensive” and “beyond the alveolar bone”. Results: Ninety-eight cancer patients were enrolled. Eighty patients (81.6%) received BTAs for over a year; 19 (19.4%) received BTAs between 13 to 24 months and 61 patients (62.2%) received BTAs for over 24 months. The majority of the patients (n=58, 59.2%) had stage 2 MRONJ and 35 (35.7%) were at MRONJ stage 3.Fifty-two (53.06%) patients were assessed with OPG and 89 (90.81%) with CBCT and CBCT was found more effective in detecting sclerosis and sequestration than OPG.Forty-three (43.87%) patients were assessed with both OPG and CBCT and were available for comparisons between OPG and CBCT. CBCT was significantly more accurate than OPG in interpreting the “beyond the alveolar bone” osteolytic changes, sclerosis, periosteal reaction and sequestration, in all MRONJ stages. P-value was 0.0002

We reported the alveolar bone histology prior to dental extractions in cancer patients, who received bone-targeting agents (BTA).Fifty-four patients were included. Patients underwent extractions, and bone biopsies were taken.Extractions were performed due to pain, swelling, purulence, fistula, and numbness, not responding to treatment, in 40 patients (group A); extractions due to asymptomatic, non-restorable teeth, were performed in 14 patients (group B). Complete alveolar jaw bone histological necrosis was observed in 28 of 40 (70%) patients of group A and none of group B (p .001). The development of clinical osteonecrosis (MRON) was assessed in 44 patients; 10 patients, who were also treated with Low Level Laser Treatments-LLLT, were excluded from this analysis, as the alternative therapies were a confounding factor. Twelve patients, with alveolar bone histological necrosis prior to extraction, developed medication-related osteonecrosis of the jaw (MRONJ) compared with two patients with vital or mixed vital/non-vital bone (p .0007). BTAs1 year and concurrent targeted therapy were also significantly associated with MRONJ (p = .016 and p = .050).Pain, swelling, purulence, fistula, and numbness were significantly associated with complete bone histological necrosis prior to extractions and increased MRONJ development. Research is justified to explore whether histological necrosis represents an early stage of osteonecrosis.

Background: Globally 43.8 million people live with cancer. A 60% increase of cancer cases is estimated by 2040, with 29.4 million patients per year requiring therapy. Optimization of cancer management, using digital innovation, is urgently needed. CureCancer is a patient-centric/driven platform, which enables patients to self-create their profile, report symptoms, and communicate with physicians. We assessed CureCancer’s feasibility and patients’ and HCPs’ satisfaction. Methods: Patients from 9 Centers were asked to register at CureCancer, upload their data and complete a questionnaire on demographics, disease and treatment characteristics, and their satisfaction. Results: 159 patients were enrolled and 144 (90.6%) registered. 114 of 144 (79.1%), 63 males and 51 females, median age 54.5 years, completed the questionnaire. 64 patients were University and 35 were high School graduates. 46 patients had metastatic disease, 87 were on active treatment and 51 received supportive care. All patients also visited non-oncology HCPs. Nineteen patients changed work status and 49 had children below 24 years. Registration was “very/very much” easy for 98 (86.0 %) patients. File uploading was “very/very much” easy for 47 (41.2%) patients. Over 80% of patients and physicians preferred the digital way. 99 patients and all HCPs will recommend CureCancer to others. Easy data access, improved communication, feeling safe, treatment adherence, interventions from distance, particularly during covid-19 pandemic and saving time and money, were highly commented by patients and HCPs. Conclusion: CureCancer was feasible, and patients and HCPs were satisfied. Patients were successful to report information on their demographics, disease and treatment characteristics. They also disclosed the need to visit non-oncology HCPs during their cancer treatment and other socioeconomic issues. Integration of CureCancer in the routine practice is expected to improve cancer care and reduce cancer costs. Patients’ self-reporting, with CureCancer, can increase the accuracy of clinical trial results and map social/work/economic issues following cancer diagnosis to assist health care policy.

The aim of this systematic review was to update the clinical practice guidelines for the use of anti-inflammatory agents in the prevention and/or treatment of oral mucositis. A systematic review was conducted by the Multinational Association of Supportive Care in Cancer/ International Society of Oral Oncology (MASCC/ISOO) subcommittee on mucositis guideline update. The body of evidence for each intervention, in each cancer treatment setting, was assigned an evidence level. The findings were added to the database used to develop the clinical practice guidelines published in 2014. Based on the evidence level, one of the following three guideline determinations was possible: recommendation, suggestion, and no guidelines. A total of 11 new papers across five interventions were examined. The recommendation for the use of benzydamine mouthwash for the prevention of radiotherapy-induced mucositis remained unchanged. New suggestion for the use of the same for prevention of mucositis associated with chemoradiotherapy was made. No guideline was possible for any other anti-inflammatory agents due to inadequate and/or conflicting evidence. Of the anti-inflammatory agents studied for oral mucositis, the evidence supports the use of benzydamine mouthwash in the specific populations listed above. Additional well-designed research is needed on other (class of agents) interventions and in other cancer treatment settings.

Purpose: The aim of this study was to update the clinical practice guidelines for the use of basic oral care (BOC) interventions for the prevention and/or treatment of oral mucositis (OM). Methods: A systematic review was conducted by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society for Oral Oncology (MASCC/ISOO). The body of evidence for each intervention in each cancer treatment setting was assigned an evidence level. The findings were added to the database used to develop the 2013 MASCC/ISOO clinical practice guidelines. Based on the evidence level, one of the following three guideline determinations was possible: Recommendation, Suggestion, No guideline possible. Results: A total of 17 new papers across six interventions were examined and merged with a previous database. Based on the literature, the following guidelines were possible. The panel suggests that the implementation of multi-agent combination oral care protocols is beneficial for the prevention of OM during chemotherapy, head and neck (H&N) radiation therapy (RT), and hematopoietic stem cell transplantation (Level of Evidence III). The panel suggests that chlorhexidine not be used to prevent OM in patients undergoing H&N RT (Level of Evidence III). No guideline was possible for professional oral care, patient education, saline, and sodium bicarbonate, and expert opinion complemented these guidelines. Conclusions: The evidence supports the use of multi-agent combination oral care protocols in the specific populations listed above. Additional well-designed research is needed on the other BOC interventions prior to guideline formulation.

Objective We present clinical and radiologic data of periodontal tissue involvement preceding the appearance of osteonecrosis of the jaw (ONJ) in 5 patients with solid tumors, who received antiresorptives alone or in combination with targeted therapies. Study Design Five patients with osteonecrosis before dental extraction were studied. Results Periodontal involvement was evidenced by pain, bleeding, fistula, purulence, swelling, periodontal pocket, and tooth mobility. Combined endoperiodontal lesions were considered in 1 patient. Duration of symptoms before ONJ diagnosis lasted 8 to 24 weeks. Routine therapy was performed in 2 of 5 patients. Widening of the periodontal ligament was observed in 4 patients, and dense alveolar bone was seen in 1 patient. Local complications of ONJ required dental extractions in 4 of 5 patients. Spontaneous tooth exfoliation was observed in 1 patient. Alveolar bone biopsies, after the extraction in 2 patients, confirmed osteonecrosis. Osteonecrosis healed in 2 patients—1 after the dental extraction and 1 after 3 dental extractions and surgical debridement. Postextraction socket healed in 1 patient, and the area with exposed bone remained asymptomatic. Osteonecrosis progressed in 2 patients. Conclusions Clinical and radiologic signs of periodontal tissue involvement, before dental extraction in patients treated with antiresorptives alone or in combination with targeted therapy, may represent developing osteonecrosis.

In the subadult age group, third molar development, as well as age-related morphological tooth information can be observed on panoramic radiographs. The aim of present study was to combine, in subadults, panoramic radiographic data based on developmental stages of third molar(s) and morphological measurements from permanent teeth, in order to evaluate its added age-predicting performances. In the age range between 15 and 23 years, 25 gender-specific radiographs were collected within each age category of 1 year. Third molar development was classified and registered according the 10-point staging and scoring technique proposed by Gleiser and Hunt (1955), modified by Köhler (1994). The Kvaal (1995) measuring technique was applied on the indicated teeth from the individuals' left side. Linear regression models with age as response and third molar-scored stages as explanatory variables were developed, and morphological measurements from permanent teeth were added. From the models, determination coefficients (R (2)) and root-mean-square errors (RMSE) were calculated. Maximal-added age information was reported as a 6 % R² increase and a 0.10-year decrease of RMSE. Forensic dental age estimations on panoramic radiographic data in the subadult group (15-23 year) should only be based on third molar development.

Introduction: Mucormycosis is a rare fungal infection, with high morbidity and mortality. Palatal ulceration may suggest a number of differential diagnoses, one of which is rhinocerebral/craniofacial mucormycosis and for which it may be the first presenting clinical finding. We report a case of sinus mucormycosis in a patient with chronic myelomonocytic leukaemia‐2 (CMML‐2), now classified in the myelodysplastic/myeloproliferative neoplasms, presenting with dental pain and palatal ulcer. Case presentation: A 72‐year‐old female with CMML‐2 presented with pain of the left maxillary molar and a dark‐brown necrotic ulcer with a white irregular border on the hard palate. Invasive fungal infection was included in the differential diagnosis. Computerized tomography disclosed inflammatory lesions in the left nasal, ethmoid and frontal sinuses. Histological examination of the ulcer showed fungal hyphae typical of agents of mucormycosis. Rhizopus arrhizus was isolated from the culture. Liposomal amphotericin B was introduced, combined with haematological support and maxillectomy. Mucormycosis was controlled, but the patient died of progressive acute myeloid leukaemia and multiple bacteraemias. A literature review of rhinocerebral mucormycosis with palatal involvement disclosed 109 cases; palatal involvement was present among other presenting signs in 34 patients and as the presenting sign leading to diagnosis in nine cases, including the present case. Six of the nine patients (66.6 %) survived the infection, compared with 43 of 101 (42.6 %) with other signs at presentation. Conclusion: Palatal ulcer may represent an early sign of sinus mucormycosis. Awareness by healthcare professionals is critical for the prompt diagnosis of this rapidly developing and life‐threatening infection.

Item does not contain fulltext OBJECTIVES: The objective of this study is to compare subjective image quality and diagnostic validity of cone-beam CT (CBCT) panoramic reformatting with digital panoramic radiographs. MATERIALS AND METHODS: Four dry human skulls and two formalin-fixed human heads were scanned using nine different CBCTs, one multi-slice CT (MSCT) and one standard digital panoramic device. Panoramic views were generated from CBCTs in four slice thicknesses. Seven observers scored image quality and visibility of 14 anatomical structures. Four observers repeated the observation after 4 weeks. RESULTS: Digital panoramic radiographs showed significantly better visualization of anatomical structures except for the condyle. Statistical analysis of image quality showed that the 3D imaging modalities (CBCTs and MSCT) were 7.3 times more likely to receive poor scores than the 2D modality. Yet, image quality from NewTom VGi(R) and 3D Accuitomo 170(R) was almost equivalent to that of digital panoramic radiographs with respective odds ratio estimates of 1.2 and 1.6 at 95% Wald confidence limits. A substantial overall agreement amongst observers was found. Intra-observer agreement was moderate to substantial. CONCLUSIONS: While 2D-panoramic images are significantly better for subjective diagnosis, 2/3 of the 3D-reformatted panoramic images are moderate or good for diagnostic purposes. CLINICAL RELEVANCE: Panoramic reformattings from particular CBCTs are comparable to digital panoramic images concerning the overall image quality and visualization of anatomical structures. This clinically implies that a 3D-derived panoramic view can be generated for diagnosis with a recommended 20-mm slice thickness, if CBCT data is a priori available for other purposes. 01 januari 2013
