Article Synopsis
- Salivary gland Secretory Carcinoma (SC) is a rare tumor first described in 2010; a study analyzed 108 cases from the REFCOR database to evaluate diagnosis, treatment, and survival rates up to July 2021.
- MRI was found to be ineffective for diagnosing malignancy, and while 79% of patients received a diagnosis after two histological readings, 21% needed molecular testing for confirmation.
- Results showed high survival rates, with 91.4% overall survival and 89% recurrence-free survival at five years, suggesting a generally positive prognosis for SC patients.*
Introduction: Salivary carcinomas of the tongue represent a therapeutic challenge as their radical excision is particularly mutilating. We aimed to study the oncologic and functional outcomes of advanced stages salivary carcinomas of the tongue.
Materials And Methods: This retrospective multicentric study, based on the French national network on rare head and neck cancers (REFCOR), included all patients with a T3-T4 salivary carcinoma of the tongue, diagnosed between January 2009 and December 2018.
Objectives: The management of the facial nerve (FN) is a major issue in parotid cancer, especially when there is no preoperative facial palsy and FN invasion is discovered intraoperatively. The aim of this study was to assess the impact of FN resection in patients with parotid cancer abutting the FN, without pretreatment facial palsy, using a propensity score matching.
Materials And Methods: Data from all patients treated between 2009 and 2020 for a primary parotid cancer abutting or invading the FN but without pretreatment facial palsy were extracted from the national multicentric REFCOR database.
Article Synopsis
- Salivary carcinomas of minor salivary glands, particularly in the tongue, are rare tumors that may require surgery and/or (chemo-)radiotherapy for treatment.
- A study involving 103 patients diagnosed between 2009 and 2018 found that the most common types were adenoid cystic and mucoepidermoid carcinomas, with surgery being the primary treatment for most cases.
- Results indicated that 5-year overall survival was 84.7%, while event-free survival was lower at 38.6%; nonsurgical treatment, alcohol use, and tumor location negatively impacted event-free survival, while nodal positivity was a key factor affecting overall survival.
Bee populations are facing numerous stressors globally, including environmental pollution by trace metals and metalloids. Understanding whether bees can detect and avoid these pollutants in their food is pivotal, as avoidance abilities may mitigate their exposure to xenobiotics. While these pollutants are known to induce sublethal effects in bees, such as disrupting physiological mechanisms, their potential impacts on locomotive abilities, fat metabolism, and reproductive physiology remain poorly understood.
