Pineal anlage tumor: A case report and clinico-pathological review.

Clin Neurol Neurosurg 2021 Jul 5;206:106629. Epub 2021 May 5.

Department of Radiotherapy and Oncology, PGIMER, Chandigarh.

Pineal anlage tumor (PAT) is an extremely rare tumor of paediatric population. It is considered as a subtype of pineoblastoma having ectomesenchymal/ rhabdomyoblastic and cartilaginous differentiation. PAT is presumed to have an aggressive behaviour with propensity for craniospinal fluid (CSF) spread due to histologically resemblance with pineoblastoma, thus requiring intensive multimodality treatment with craniospinal irradiation and chemotherapy.

Part-time cancers and role of melatonin in determining their metabolic phenotype.

Life Sci 2021 Aug 8;278:119597. Epub 2021 May 8.

Departamento de Biologia Estrutural e Funcional, Instituto de Biociencias, Botucatu, Sao Poalo 18618-689, Brazil.

This brief review describes the association of the endogenous pineal melatonin rhythm with the metabolic flux of solid tumors, particularly breast cancer. It also summarizes new information on the potential mechanisms by which endogenously-produced or exogenously-administered melatonin impacts the metabolic phenotype of cancer cells. The evidence indicates that solid tumors may redirect their metabolic phenotype from the pathological Warburg-type metabolism during the day to the healthier mitochondrial oxidative phosphorylation on a nightly basis.

Intracranial spread of a systemic malignancy is common in advanced staged cancers; however, metastasis specifically to the pineal gland is a relatively rare occurrence. A number of primary lesions have been reported to metastasize to the pineal gland, the most common of which is lung. However, metastasis of a bronchial neuroendocrine tumor to the pineal gland is a seldom-reported entity. Read More

PTEN R130Q Papillary Tumor of the Pineal Region (PTPR) with Chromosome 10 Loss Successfully Treated with Everolimus: A Case Report.

Curr Oncol 2021 Mar 20;28(2):1274-1279. Epub 2021 Mar 20.

Department of Pediatric Neurology, Faculty of Medicine, Lebanese University, Beirut P.O. Box 6573/14, Lebanon.

Papillary tumors of the pineal region (PTPR) can be observed among adults with poor prognosis and high recurrence rates. Standards of therapy involve total surgical excision along with radiation therapy, with no promising prospects for primary adjuvant chemotherapy, as long-term treatment options have not been explored. Chromosome 10 loss is characteristic of PTPR, and gene alterations are frequently encountered in a wide range of human cancers and may be treated with mTORC1 inhibitors such as everolimus. Read More

Cancers (Basel) 2021 Mar 27;13(7). Epub 2021 Mar 27.

Anatomy and Physiopathology Division, Department of Clinical and Experimental Sciences, University of Brescia, 25123 Brescia, Italy.

The pineal gland is a small, pinecone-shaped endocrine gland that participates in the biological rhythm regulation of vertebrates. The recognized major product of the pineal gland is melatonin-a multifunctional endogenous indoleamine. Accumulating evidence suggests that the pineal gland is important for preserving ideal health conditions in vertebrate. Read More

Clinical and molecular heterogeneity of pineal parenchymal tumors: a consensus study.

Acta Neuropathol 2021 05 22;141(5):771-785. Epub 2021 Feb 22.

Department of Developmental Neurobiology, St. Jude Children's Research Hospital, Memphis, TN, USA.

Recent genomic studies have shed light on the biology and inter-tumoral heterogeneity underlying pineal parenchymal tumors, in particular pineoblastomas (PBs) and pineal parenchymal tumors of intermediate differentiation (PPTIDs). Previous reports, however, had modest sample sizes and lacked the power to integrate molecular and clinical findings. The different proposed molecular group structures also highlighted a need to reach consensus on a robust and relevant classification system. Read More
