AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS AND AMERICAN COLLEGE OF ENDOCRINOLOGY DISEASE STATE CLINICAL REVIEW: TIMING OF MULTIPLE ENDOCRINE NEOPLASIA THYROIDECTOMY AND EXTENT OF CENTRAL NECK LYMPHADENECTOMY

[Hereditary cancer syndromes: a modern paradigm]

About 5-10% of malignant neoplasms (MN) are hereditary. Carriers of mutations associated with hereditary tumor syndromes (HTS) are at high risk of developing tumors in childhood and young age and synchronous and metachronous multiple tumors. At the same time, this group of diseases remains mainly an oncological problem, and clinical decisions are made only when MNs are detected in carriers of pathogenic mutations.Individual recommendations for cancer screening, treatment, and prevention should be developed for carriers of mutations associated with HTS to prevent an adverse outcome of the disease. It is essential to identify patients at risk by doctors of all specialties for further referral to medical and genetic counseling with molecular genetic testing (in case of indications). The problems of standardization of enrollment criteria for genetic tests, further tactics of prevention, screening, and treatment of many hereditary oncological diseases remain unsolved.This review was created to inform doctors of various specialties, including endocrinologists, about the HTS. This allows them to get acquainted with main clinical features of specific syndromes, helps to understand the difference between hereditary and non-hereditary cancer, recognize signs of hereditary cancer, and introduce the indications for genetic examination and genetic counseling of the patient. Also, significant differences between international and domestic recommendations on screening measures, diagnosis, and treatment of HTS underline the need to review the existing and develop new algorithms for medical support of patients with HTS.

From the laboratory bench to the operating room: the role of the surgeon in cancer prevention

BACKGROUND

The last 200 years have seen remarkable achievements in the art and clinical practice of surgery. These advances include the introduction of antisepsis, anesthesia, vascular anastomosis, antimicrobials, organ transplantation, and the widespread application of minimally invasive operative procedures. Very recently, a surgical procedure has been shown to cure diabetes, representing the most effective treatment of a metabolic disorder by surgeons.

METHODS

The author reviewed the major surgical milestones in the modern surgical era and prepared this monograph for presentation as the Claude H. Organ, Jr. Memorial Lecture at the 68^th Annual Meeting of the Southwestern Surgical Congress.

RESULTS/CONCLUSIONS

This address summarizes the story of medullary thyroid carcinoma and multiple endocrine neoplasia type 2, an archetype for a surgical procedure to prevent cancer development.
