Critical Reviews in Oncology/Hematology | Year: 2016

Paranasal sinus cancers are rare diseases, accounting for about 5% of all head and neck malignancies. The variety of histological types and the overlapping pathological features with other entities constitute difficulties in pathologic interpretation, often requiring a skilled interpretation or a second opinion. Treatment of locally advanced disease relies on surgery and radiation therapy for operable disease, with a possible role for systemic treatment in selected histologies within a multimodal approach; unresectable paranasal sinus cancers are generally treated with a combination of radiotherapy and chemotherapy. The employment of high conformal radiation techniques, such as Intensity Modulated Radiation Therapy orcharged particle therapy, proton or carbon ion therapy may improve outcome and reduce late effects. Surgical treatment has evolved due to the progressive application of transnasal endoscopic techniques for naso-ethmoidal malignancies and due to innovative reconstructive techniques after resection of cancers of the maxillary sinus. Because of the rarity and complexity of this disease, multicenter trials represent an urgent need to improve prognosis and to reduce treatment-related effects. © 2015 Elsevier Ireland Ltd. Source

Thyroid | Year: 2015

Background: The choroid is a rare site of thyroid cancer metastases, and has been described in patients with evidence of advanced breast, lung, and prostate carcinomas. To the authors' knowledge, only seven reported cases exist with choroidal metastasis secondary to papillary thyroid carcinoma (PTC). This study describes an additional patient with metastatic PTC with simultaneous appearance of choroidal mass and cutaneous deposits while on systemic therapy with a tyrosine kinase inhibitor (TKI). These infrequent sites of metastasis are typically associated with a dismal prognosis following the diagnoses. However, this patient has not shown evidence of choroid or cutaneous recurrence one year following local targeted and systemic therapy. Patient findings: The case is presented of a 70-year-old male with widely metastatic PTC to the lymph nodes, lung, and mediastinum who was found to have choroidal metastasis six years after his initial diagnosis. Summary: The patient was asymptomatic and was found to have an incidental right choroidal mass on routine ophthalmology exam. Magnetic resonance imaging of the orbit revealed an isolated right choroid lesion suspicious for melanoma or metastasis. Concurrent to this discovery, he was noted to have progression of the lung and mediastinal disease along with new dermal lesions on the chest wall suspicious for dermal metastasis. Both the choroid and dermal metastases occurred while being on a TKI. Given his previous history of male breast carcinoma, a biopsy of the choroid was performed, which confirmed PTC. The patient developed endophthalmitis and subsequently underwent enucleation of the right eye. The choroid mass was completely excised, measured 3.5 mm×9.5 mm with negative margins, and histopathology was consistent with metastatic PTC. Pulmonary, mediastinal, and cutaneous lesions regressed after external beam radiation therapy, following which systemic therapy was changed to a different multikinase inhibitor. Conclusion: A rare and unique case is reported of choroidal metastasis from PTC that presented with concurrent new dermal metastasis in addition to lung and mediastinal lymph node progression. Furthermore, the patient developed choroid and dermal lesions while on a TKI and remained stable without recurrence in these regions after switching to an alternate multikinase inhibitor. © 2015, Mary Ann Liebert, Inc.

Purpose: There is a limited number of therapies with a high level of recommendations for mucositis, while several strategies are currently employed with a limited evidence for efficacy. A national survey among Italian oncologists who treat head and neck cancer (HNC) was conducted in order to assess the most common preventive and therapeutic protocols (including nutritional support and pain control) for oral mucositis (OM) in patients undergoing chemoradiotherapy. Methods: From September to November 2012, a nationwide electronic survey with 21 focused items was proposed to chemotherapy and radiotherapy centers. Results: We collected 111 answers. Common Terminology Criteria for Adverse Events (CTCAE) scale is employed by 55 % of the physicians in assessing mucosal toxicity. The most relevant predictive factors for OM development are considered smoke, alcohol use, planned radiotherapy, and concurrent use of radiosensitizing chemotherapy. Prophylactic gastrostomy is adopted in <10 % of the patients. Preventive antibiotics or antimycotics are prescribed by 46 % of the responders (mainly local or systemic antimycotic drugs). Alkalinizing mouthwashes or coating agents are frequently adopted (70 % of the cases). Among therapeutic interventions, systemic fluconazole is administered by 80 % of the physicians. Pain is mainly treated by weak followed by strong opioids. Conclusions: A variety of preventive and therapeutic protocols for OM exists among the participating Italian centers, with some uniformity in respect to nutritional support, use of antimycotic and painkillers. There is an urgent need for well-conducted clinical trials aimed at assessing the best choices for OM prevention and treatment in HNC. © 2014 Springer-Verlag. Source

Purpose: The purpose of this study was to estimate the risk and severity of oral and gastrointestinal mucosal toxicities associated with selected targeted agents. Methods: We searched the English-language literature in February 2011 for reports of randomized clinical trials comparing a FDA-approved targeted agent to a standard of care regimens. Long-term follow-up and secondary reports of trials were excluded, leaving 85 studies for analysis. Using meta-analytic methods, we calculated the relative risks of oral and gastrointestinal toxicities, adjusting for sample size using the inverse variance technique. For each targeted agent and each side effect, we calculated the number needed to harm, the number of patients that, if treated with the more toxic regimen, would produce one additional episode of the toxicity. Results: Oral mucositis was significantly more frequent among patients treated with bevacizumab, erlotinib, sorafenib, or sunitinib, although this difference was confined to low-grade mucositis. The clinical significance of these findings is unclear given its low incidence and mild severity. In contrast, diarrhea was significantly more frequent with most of the targeted agents studied, with adjusted relative risks between 1.5 and 4.5. An additional patient with diarrhea will be observed for every three to five patients treated with these targeted agents, compared with conventional regimens. Conclusions: Oral mucosal toxicities occasionally complicate treatment with these targeted agents, but the clinical significance of this finding is not clear. Diarrhea is a hallmark of treatment with these targeted agents; this side effect should be carefully ascertained to permit early intervention and control. © 2013 Springer-Verlag Berlin Heidelberg.

Purpose: The aim of this project was to develop clinical practice guidelines on the use of antimicrobials, mucosal coating agents, anesthetics, and analgesics for the prevention and management of oral mucositis (OM) in cancer patients. Methods: A systematic review of the available literature was conducted. The body of evidence for the use of each agent, in each setting, was assigned a level of evidence. Based on the evidence level, one of the following three guideline determinations was possible: recommendation, suggestion, or no guideline possible. Results: A recommendation was developed in favor of patient-controlled analgesia with morphine in hematopoietic stem cell transplant (HSCT) patients. Suggestions were developed in favor of transdermal fentanyl in standard dose chemotherapy and HSCT patients and morphine mouth rinse and doxepin rinse in head and neck radiation therapy (H&N RT) patients. Recommendations were developed against the use of topical antimicrobial agents for the prevention of mucositis. These included recommendations against the use of iseganan for mucositis prevention in HSCT and H&N RT and against the use of antimicrobial lozenges (polymyxin-tobramycin-amphotericin B lozenges/paste and bacitracin-clotrimazole-gentamicin lozenges) for mucositis prevention in H&N RT. Recommendations were developed against the use of the mucosal coating agent sucralfate for the prevention or treatment of chemotherapy-induced or radiation-induced OM. No guidelines were possible for any other agent due to insufficient and/or conflicting evidence. Conclusion: Additional well-designed research is needed on prevention and management approaches for OM. © 2013 Springer-Verlag Berlin Heidelberg. Source
