Prostate cancer is the most frequently diagnosed cancer among elderly men in the United States. Skeletal architecture is affected by metastasis and androgen deprivation therapy (ADT), which is considered a gold standard treatment in prostate cancer. Osteoporosis and skeletal effects are reported among most patients on ADT. To counter these effects and to reduce bone turnover, antiresorptive drugs such as bisphosphonates and denosumab are commonly prescribed in prostate cancer. These drugs increase the prevalence of osteonecrosis of the jaw in a subset of patients. The future should hold promise for new drugs that could have a positive impact on bone metabolism without jeopardizing bone integrity. [ABSTRACT FROM AUTHOR]

Objective: To update the clinical practice guidelines for the management of oral mucositis (OM) that were developed by the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO). This part focuses on honey, herbal compounds, saliva stimulants, probiotics, and miscellaneous agents.Methods: A systematic review was conducted by the Mucositis Study Group of MASCC/ISOO. The body of evidence for each intervention, in each clinical setting, was assigned an evidence level. The findings were added to the database used to develop the 2014 MASCC/ISOO clinical practice guidelines. Based on the evidence level, one of the following guidelines were determined: Recommendation, Suggestion, No Guideline Possible.Results: A total of 78 papers were identified within the scope of this section, of which 49 were included in this review and merged with nine publications that were reported in the previous guidelines update. A new Suggestion was made for honey (combined topical and systemic delivery) for the prevention of OM in head and neck cancer patients receiving radiotherapy with or without chemotherapy. A new Suggestion clarified that chewing gum is not effective for the prevention of OM in pediatric patients with hematological or solid cancer treated with chemotherapy. No guideline was possible for other interventions.Conclusions: Numerous natural products and herbal remedies were studied for the management of OM. Of the agents reviewed in this systematic review, a guideline in favor was made for honey (combined topical and systemic), while a guideline against was made for chewing gum. Additional research is warranted to clarify the potential of other interventions. [ABSTRACT FROM AUTHOR]

Purpose: To update the clinical practice guidelines for the use of antimicrobials, mucosal coating agents, anesthetics, and analgesics 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 of 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 2014 MASCC/ISOO clinical practice guidelines. Based on the evidence level, the following guidelines were determined: Recommendation, Suggestion, and No Guideline Possible.Results: A total of 9 new papers were identified within the scope of this section, adding to the 62 papers reviewed in this section previously. A new Suggestion was made for topical 0.2% morphine for the treatment of OM-associated pain in head and neck (H&N) cancer patients treated with RT-CT (modification of previous guideline). A previous Recommendation against the use of sucralfate-combined systemic and topical formulation in the prevention of OM in solid cancer treatment with CT was changed from Recommendation Against to No Guideline Possible. Suggestion for doxepin and fentanyl for the treatment of mucositis-associated pain in H&N cancer patients was changed to No Guideline Possible.Conclusions: Of the agents studied for the management of OM in this paper, the evidence supports a Suggestion in favor of topical morphine 0.2% in H&N cancer patients treated with RT-CT for the treatment of OM-associated pain.

Purpose: To update the clinical practice guidelines for the use of growth factors and cytokines 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 of 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 2014 MASCC/ISOO clinical practice guidelines. Based on the evidence level, the following guidelines were determined: recommendation, suggestion, and no guideline possible.Results: A total of 15 new papers were identified within the scope of this section and were merged with 51 papers that were reviewed in the previous guidelines update. Of these, 14, 5, 13, 2, and 1 were randomized controlled trials about KGF-1, G-CSF, GM-CSF, EGF, and erythropoietin, respectively. For the remaining agents there were no new RCTs. The previous recommendation for intravenous KGF-1 in patients undergoing autologous hematopoietic stem cell transplantation (HSCT) conditioned with high-dose chemotherapy and TBI-based regimens is confirmed. The previous suggestion against the use of topical GM-CSF for the prevention of OM in the setting of high-dose chemotherapy followed by autologous or allogeneic stem cell transplantation remains unchanged.Conclusions: Of the growth factors and cytokines studied for the management of OM, the evidence supports a recommendation in favor of KGF-1 and a suggestion against GM-CSF in certain clinical settings.

Purpose: The aim of this study was to update the clinical practice guidelines for the use of agents for the prevention and/or treatment of gastrointestinal mucositis (GIM).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. Based on the evidence level, one of the following three guideline determinations was possible: Recommendation, Suggestion, and No Guideline Possible.Results: A total of 78 papers across 13 interventions were examined of which 25 were included in the final review. No new guidelines were possible for any agent due to inadequate and/or conflicting evidence. Existing guidelines for probiotics and hyperbaric oxygen were unchanged.Conclusions: Of the agents studied for the prevention and treatment of GIM, the evidence continues to support use of probiotics containing Lactobacillus spp. for prevention of chemoradiotherapy and radiotherapy-induced diarrhea in patients with pelvic malignancy, and hyperbaric oxygen therapy to treat radiation-induced proctitis. Additional well-designed research is encouraged to enable a decision regarding palifermin, glutamine, sodium butyrate, and dietary interventions, for the prevention or treatment of GIM.

Purpose: To systematically review the literature and update the evidence-based clinical practice guidelines for the use of photobiomodulation (PBM), such as laser and other light therapies, 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) using PubMed and Web of Science. We followed the MASCC methods for systematic review and guidelines development. The rigorously evaluated evidence for each intervention, in each cancer treatment setting, was assigned a level-of-evidence (LoE). Based on the LoE, one of the following guidelines was determined: Recommendation, Suggestion, or No Guideline Possible.Results: Recommendations are made for the prevention of OM and related pain with PBM therapy in cancer patients treated with one of the following modalities: hematopoietic stem cell transplantation, head and neck (H&N) radiotherapy (without chemotherapy), and H&N radiotherapy with chemotherapy. For each of these modalities, we recommend 1-2 clinically effective protocols; the clinician should adhere to all parameters of the protocol selected. Due to inadequate evidence, currently, No Guideline Possible for treatment of established OM or for management of chemotherapy-related OM. The reported clinical settings were extremely variable, limiting data integration.Conclusions: The evidence supports the use of specific settings of PBM therapy for the prevention of OM in specific patient populations. Under these circumstances, PBM is recommended for the prevention of OM. The guidelines are subject to continuous update based on new published data. [ABSTRACT FROM AUTHOR]

New studies and literature continue to emerge on the management of mucositis secondary to cancer therapy. The evidence-based clinical practice guidelines for mucositis were first published in 2004 and updated in 2007 and 2014 by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO). The existing 2014 guidelines for mucositis are being updated in line with new literature to inform clinical practice. This paper describes the materials and methods employed for the comprehensive updates to the guidelines for managing mucositis. [ABSTRACT FROM AUTHOR]

Purpose: 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.Methods: 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.Results: 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.Conclusions: 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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Odontogenic myxofibroma (MF) is a benign odontogenic neoplasm that predominantly occurs in the mandible. It is a variant of odontogenic myxoma. There are several case reports of odontogenic MF reported in the literature. However, none of them were associated with a past history of malignancy. This article presents a case of odontogenic MF in a patient with a past history of treated carcinoma of the breast and rectum. [ABSTRACT FROM AUTHOR]
