Background: Publication of the 2015 American Thyroid Association (ATA) management guidelines for adult patients with thyroid nodules and differentiated thyroid cancer was met with disagreement by the extended nuclear medicine community with regard to some of the recommendations related to the diagnostic and therapeutic use of radioiodine (131 I). Because of these concerns, the European Association of Nuclear Medicine and the Society of Nuclear Medicine and Molecular Imaging declined to endorse the ATA guidelines. As a result of these differences in opinion, patients and clinicians risk receiving conflicting advice with regard to several key thyroid cancer management issues. Summary: To address some of the differences in opinion and controversies associated with the therapeutic uses of 131 I in differentiated thyroid cancer constructively, the ATA, the European Association of Nuclear Medicine, the Society of Nuclear Medicine and Molecular Imaging, and the European Thyroid Association each sent senior leadership and subject-matter experts to a two-day interactive meeting. The goals of this first meeting were to (i) formalize the dialogue and activities between the four societies; (ii) discuss indications for 131 I adjuvant treatment; (iii) define the optimal prescribed activity of 131 I for adjuvant treatment; and (iv) clarify the definition and classification of 131 I-refractory thyroid cancer. Conclusion: By fostering an open, productive, and evidence-based discussion, the Martinique meeting restored trust, confidence, and a sense of collegiality between individuals and organizations that are committed to optimal thyroid disease management. The result of this first meeting is a set of nine principles (The Martinique

Background: The American Thyroid Association (ATA), the European Association of Nuclear Medicine, the European Thyroid Association, and the Society of Nuclear Medicine and Molecular Imaging have established an intersocietal working group to address the current controversies and evolving concepts in thyroid cancer management and therapy. The working group annually identifies topics that may significantly impact clinical practice and publishes expert opinion articles reflecting intersocietal collaboration, consensus, and suggestions for further research to address these important management issues. Summary: In 2019, the intersocietal working group identified the following topics for review and interdisciplinary discussion: (i) perioperative risk stratification, (ii) the role of diagnostic radioactive iodine (RAI) imaging in initial staging, and (iii) indicators of response to RAI therapy. Conclusions: The intersocietal working group agreed that (i) initial patient management decisions should be guided by perioperative risk stratification that should include the eighth edition American Joint Committee on Cancer staging system to predict disease specific mortality, the modified 2009 ATA risk stratification system to

In this paper, we present data from the Martinique Cancer Registry for the period 1981-2000 and interpret cancer incidence trends in the light of risk factor patterns. In Martinique, cancer data are available from 1981. The sources of information are represented by insurance records, medical evacuations, hospitals and laboratory files. We performed a Mantel-Haenszel chi test stratified on age in order to assess time trends and to compare incidence rates between men and women over the whole period. A total of 8992 incidents of cancer cases were recorded during the last 20 years among men and 6832 in women. (The overall age-standardized incidence rate is 222 per 10 person-years for men and 145 per 10 person-years for women.) The most common cancers are prostate cancer in men (104 per 10 person-years) and breast cancer in women (42 per 10 person-years). Except for thyroid and salivary gland cancer, men experienced higher incidence rates for all other cancers. Incidence of prostate cancer in men, breast cancer in women and colorectal cancer in both sexes strongly increased between 1981-1990 and 1991-2000, whereas no significant variation was observed for that of all digestive cancers together. Among women, cervical cancer incidence strongly decreased. These results demonstrate that Martinique tends to have the same cancer risk profile as France Mainland with, however, higher incidence rates for cervical, stomach and prostate cancer. Changes in lifestyle and greater accessibility to diagnostic and therapeutic procedures, in particular screening, have strongly contributed to the 'epidemiological transition' observed.
