Adenoid cystic carcinoma (ACC) is a rare malignant tumor of the salivary glands, with higher frequency in the submandibular gland, a prolonged clinical course, and poor long‐term survival. It tends to metastasize to lungs, bone, liver, brain, and rarely to skin BACKGROUNDAdenoid cystic carcinoma (ACC) is a rare malignancy arising in salivary glands and other sites, characterized by high rates of relapse and distant spread. Recurrent/metastatic (R/M) ACCs are generally incurable, due to a lack of active systemic therapies. To improve outcomes, deeper unders Adenoid cystic carcinoma (ACC) is a rare cancer with high potential for recurrence and metastasis. Efficacy of current treatment options, particularly for advanced disease, is very limited. Recent whole genome and exome sequencing has dramatically improved our understanding of ACC pathogenesis Background: We examined the assumption in conventional teaching about metastatic adenoid cystic carcinoma (ACC) being an indolent type of disease
Adenoid cystic carcinoma tends to invade the nerves and cause distant hematogenous metastasis (3), which is usually observed in the lungs (4), whereas renal metastasis is commonly observed in lung, breast and other cancers (5). Renal metastasis of a submandibular gland adenoid cystic carcinoma is rare Adenoid cystic carcinomas (ACCs) are rare tumors, and mostly arise from salivary gland, especially minor salivary glands.1They can also arise in various sites of the head and neck including the tracheobronchial tree and even in sites outside the head and neck, such as breast, uterine cervix, prostate, and the skin.2They have paradoxical behaviors . Physicians do not have a clear standard of care or approved drugs to recommend to ACC patients with advanced disease, so treatment plans are highly individualized and patient preferences often drive the final decision Purpose: We evaluated the safety and efficacy of pembrolizumab (pembro) ± radiation therapy (RT) in a phase 2 study among patients with progressive, metastatic adenoid cystic carcinoma (ACC). Methods and materials: Eligible patients had metastatic ACC with progression within the last year and ≥1 measurable lesion. Patients were randomized to pembro alone or with RT to 30 Gy in 5 fractions. Doctors treat adenoid cystic carcinoma as a chronic condition. Remote metastases can occur a decade or more after initial treatment of the primary tumor, with the most common metastatic locations being the lung, bone, and viscera

Adenoid cystic carcinoma (ACC) is a rare tumor, usually arising in the salivary gland, accounting for 1% of all head and neck cancers. ACC may have a long-term poor prognosis, as about 40% of radically treated patients will recur locoregionally and up to 60% will develop distant metastasis 6022 Background: Recurrent/metastatic adenoid cystic carcinoma (R/M ACC) is a malignant neoplasm of salivary gland origin with no standard treatment. The majority of ACCs are characterized by MYB over-expression which correlates to upregulation of several genes, including lenvatinib-relevant targets such as vascular endothelial growth factor A, the receptor tyrosine kinase KIT and fibroblast. The incidence of neck metastases in adenoid cystic carcinoma of the head and neck is considered low and reported incidence range from 0 to 18%. If tumors of the submaxillary gland are considered separately, the incidence of neck metastases reported ranges from 0 to loo%, with a pooled incidence of 34%, signifi 6026 Background: There is no specific therapy, including targeted agents, has consistently improved clinical outcomes in recurrent/metastatic adenoid cystic carcinoma of the head and neck (ACCHN). Recently, anti-angiogenic targeted therapy represents a potential effective strategy. We conducted a single-arm, phase II trial to evaluate apatinib, a small-molecule inhibitor of VEGFR-2, in ACCHN. ACC (Adenoid Cystic Carcinoma) is a rare and unique form of cancer that is known to be unpredictable in nature, with a typical growth pattern of being slow and gradual, but over time can be progressive, insidious and relentless. There are some general tendencies, such as the propensity for it to spread into surrounding nerve tissue or.
Adenoid cystic carcinoma (ACC) is a rare salivary gland malignant neoplasm. Clinically it represents as an indolent yet a persistent lesion, which shows propensity for late distant metastases, involving vital tissues often leading to the death of the patient. Its innoceous clinical presentation remains a diagnostic challenge 6082 Background: Adenoid cystic carcinoma (ACC) is a salivary gland malignancy characterized by a high rate of distant recurrence. Systemic therapy has generally failed to produce durable benefit. Radiation (RT) is used for localized disease and as directed treatment for metastases. Here, we report the safety and efficacy of pembrolizumab (pembro) administered with or without hypofractionated. Adenoid cystic cancer (ACC) is the most common SGC histotype observed in metastatic subjects (60%) and distant metastases are the principal cause of failure, being diagnosed in 25-55% of the patients. First-line treatment is palliative chemotherapy that is typically not associated with any benefit neither in response rate nor in outcome Adenoid cystic carcinoma is a rare malignant tumor arising from exocrine glands such as the major and minor salivary glands of the paranasal sinuses or the external auditory canal. Although multiple retrospective clinical studies of ACC have been reported to date, clinical questions, such as 1) long-term prognosis beyond 20 years, 2) usefulness and suitability for treatment of therapeutic.
Adenoid cystic carcinoma (ACC) is a rare malignant tumor of the salivary glands, with higher frequency in the submandibular gland, a prolonged clinical course, and poor long‐term survival.It tends to metastasize to lungs, bone, liver, brain, and rarely to skin. Comprehensive skin examination and appropriate follow‐up is recommended, since cutaneous metastasis represents disease progression. However, postoperative immunohistochemical analysis showed that the tumor was a metastatic adenoid cystic carcinoma. During the secondary pulmonary relapse, although the tumor was correctly diagnosed as a metastatic adenoid cystic carcinoma by intraoperative examination, it again mimicked primary lung adenocarcinoma
Purpose: Vorinostat is a histone deacetylase inhibitor (HDACi). Based on a confirmed partial response (PR) in an adenoid cystic carcinoma (ACC) patient treated with vorinostat in a prior phase 1 trial, we initiated this phase 2 trial Introduction. Adenoid cystic carcinoma is a malignant neoplasm that arises within the secretory glands, most commonly in the salivary glands of the head and neck ().Salivary adenoid cystic carcinoma (SACC), which arises from ductal, myoepithelial, and basal cells, comprises approximately 25% of the malignant tumors in the major salivary glands and approximately 50% of those in the minor glands ()
PURPOSE: The role of chemotherapy in adenoid cystic carcinoma (ACC) is controversial because ACC is usually stable without chemotherapy and lack of randomized trials. Here, we conducted the first randomized trial to evaluate the efficacy of axitinib as compared to observation in ACC. PATIENTS AND METHODS: In this multicenter, prospective phase II trial, we enrolled patients with recurrent or. Preclinical results for AL101 monotherapy in patient-derived xenograft models of adenoid cystic carcinoma were presented at the 2019 American Association for Cancer Research Annual Meeting. 2 The agent had previously been explored in a phase I trial of patients with locally advanced or metastatic solid tumors and had demonstrated a partial.

Adenoid Cystic Carcinoma (AdCC) is a very rare form of cancer which can occur in various parts of the body. The neck and head are the most common sites of occurrence of this type of cancer. AdCC usually affects the major as well as the minor salivary glands. The distinctive histologic appearance is the main characteristic of this type of neoplasm The multitargeted tyrosine kinase inhibitor lenvatinib had antitumor activity in patients with recurrent or metastatic adenoid cystic carcinoma (ACC), but required active monitoring and management.
Adenoid cystic carcinomas mostly occur in the salivary glands. Other primary sites of involvement include the lacrimal gland, the larynx, and the lungs. Adenoid cystic carcinomas spread along nerve sheaths, resulting in severe pain, and they tend to recur. Lymph node metastases are unusual; hematogenous tumor spread is characteristic Introduction: Laryngeal adenoid cystic carcinoma (LACC) is an extremely rare malignant neoplasm. The etiology of LACC remains unknown, and it is characterized by multiple recurrences, slow progression, and late distant metastasis Genetic hallmarks of recurrent/metastatic adenoid cystic carcinoma.
