Endocrine therapy plays a crucial role in the treatment of women with hormone receptor-positive breast cancer. However, non-adherence remains a frequent issue known to negatively impact survival. Based on a comprehensive literature review, this article explores the terminologies employed to describe adherence and methods used for its assessment, the adherence data reported with adjuvant endocrine therapy with targeted therapies, the determinants of adherence or non-adherence, and finally, tested solutions to address it. The results show that a better understanding of the causes of non-adherence would help to better identify patients at risk, and to develop personalized intervention programs capable of improving adherence to adjuvant endocrine therapy. In light of the literature, interventions are likely to require a multimodal approach and integration into our future healthcare pathways., (Copyright © 2024 Société Française du Cancer.

Refractory thyroid cancers include radio-iodine-refractory cancers, metastatic or locally advanced unresectable medullary and anaplastic thyroid cancers. Their management has been based for several years on the use of multi-target kinase inhibitors, with anti-angiogenic action, with the exception of anaplastic cancers usually treated with chemo- and radiotherapy. The situation has recently evolved due to the availability of molecular genotyping techniques allowing the discovery of rare but targetable molecular abnormalities. New treatment options have become available, more effective and less toxic than the previously available multi-target kinase inhibitors. The management of refractory thyroid cancers is therefore becoming more complex both at a diagnosis level with the need to know when, how and why to look for these molecular abnormalities but also at a therapeutic level, innovative treatments being hardly accessible. The cost of molecular analyzes and the access to treatments need also to be homogenized because disparities could lead to inequality of care at a national or international level. Finally, the strategy of identifying molecular alterations and treating these rare tumors reinforces the importance of a discussion in a multidisciplinary consultation meeting., (Copyright © 2021 Société Française du Cancer.

Low vitamin D plasmatic rates have been correlated to an increased risk of developing cancer. It has been proved that vitamin D could facilitate cell differentiation and have anti-inflammatory, anti-angiogenic and pro-apoptotic effects. Epidemiological studies are likely to show a protective role regarding colon cancer and possibly towards breast cancer., (Copyright © 2013 Elsevier Masson SAS. All rights reserved.)

Average 20% of the cancer patients will have bone metastasis most of time painful and with variable clinical expressions. Due to animal models, the bone metastasis pain is better known and it explains the different treatments mechanisms. After a suitable evaluation of the pain, several therapeutic approaches can be suggested. In addition to the classical analgesics, several medications are known to be efficient in few indications like neuropathic pain. Besides a local surgery, an external radiotherapy or an interventional radiology treatment can often be useful along with a medical treatment. When there is a bone progression, the anti-cancer treatment by chemotherapy, hormonotherapy or targeted therapies must always be reviewed, because if efficient it could have an analgesic action.
