While the vast majority of cancers are believed to occur sporadically, most forms of cancer, both adult and paediatric, have a hereditary equivalent. In the case of adult malignancies, these include hereditary breast and ovarian cancer and syndromes such as the multiple endocrine neoplasias types 1 and 2 characterised by specific tumours of the endocrine gland system. In the case of paediatric malignancies, these include syndromes such as retinoblastoma and Wilms tumour. In a little over a single decade, we have seen a tremendous increase in the knowledge of the primary genetic basis of many of the familial cancer syndromes. The majority of familial syndromes are inherited as autosomal dominant traits including hereditary colon cancer and familial malignant melanoma, however, the genetics behind autosomal recessive disorders such as Bloom syndrome and Fanconi anaemia are also being elucidated. A third mode of inheritance less well understood in the setting of familial cancer is that of imprinting recently observed in a subset of families with inherited paraganglioma. In this review, we discuss 31 genes inherited in an autosomal dominant manner associated with 20 familial cancer syndromes. Genes inherited in an autosomal recessive manner linked to familial cancer syndromes are also discussed. The identification of genes associated with familial cancer syndromes has in some families enabled a 'molecular diagnosis' that complements clinical assessment and allows directed cancer surveillance for those individuals determined to be at-risk of disease.

36 patients were operated on lung cancer (30), trachea (1), lung colon cancer metastases (1), left atrium paraganglioma, bronchogenic thymic cyst (1) and lung tuberculoma (2). Competing cardio-vascular diseases were as follows: coronary heart disease (30), valve failure (3) and critical stenosis of internal carotid artery (3). Simultaneous operations were performed in 13 (36.1%), consecutive - in 23 patients. Non-complicated postoperative period was registered in 19 patients. 6 of them had simultaneous surgery and 13 were operated on consecutively. Overall mortality rate was 8.3%; among patients operated on simultaneously it was 15.4%, among patients of the second group - 4.3%. There were no postoperative deaths among patients, operated first on cardio-vascular system.

Next-generation or massively parallel sequencing has transformed the landscape of genetic testing for cancer susceptibility. Panel-based genetic tests evaluate multiple genes simultaneously and rapidly. Because these tests are frequently offered in clinical settings, understanding their clinical validity and utility is critical. When evaluating the inherited risk of breast and ovarian cancers, panel-based tests provide incremental benefit compared with BRCA1/2 genetic testing. For inherited risk of other cancers, such as colon cancer and pheochromocytoma-paraganglioma, the clinical utility and yield of panel-based testing are higher; in fact, simultaneous evaluation of multiple genes has been the historical standard for these diseases. Evaluating inherited risk with panel-based testing has recently entered clinical practice for prostate and pancreatic cancers, with potential therapeutic implications. The resulting variants of uncertain significance and mutations with unclear actionability pose challenges to service providers and patients, underscoring the importance of genetic counseling and data-sharing initiatives. This review explores the evolving merits, challenges, and nuances of panel-based testing for cancer susceptibility.

Reversible cerebral vasoconstriction syndrome (RCVS) is characterised by severe thunderclap headaches (with or without the presence of acute neurological symptoms) and segmental vasoconstriction of cerebral arteries that resolves spontaneously in a period of three months. Cases have been described in the literature with producing and non-producing masses of metanephrines. Within these reports, associations with cavernous haemangioma, medulloblastoma, colon cancer, paraganglioma, pheochromocytoma, uterine fibroids, among others were found. However, no association with adrenal masses which do not produce metanephrines was found. In this context, we reported the case of a woman with this type of tumour associated with RCVS which provided a treatment challenge, as well as we reviewed the literature on cases of RCVS associated with masses.
