Clinically relevant bone metastases are a major cause of morbidity and mortality for prostate cancer patients. Distinct phenotypes are described: osteoblastic, the more common osteolytic and mixed. A molecular classification has been also proposed. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor–host interactions, as described by the “metastatic cascade” model. Understanding these mechanisms, although far from being fully elucidated, could offer several potential targets for prevention and therapy. Moreover, the prognosis of patients is markedly influenced by skeletal-related events. They can be correlated not only with bone metastases, but also with “bad” bone health. There is a close correlation between osteoporosis—a skeletal disorder with decreased bone mass and qualitative alterations—and prostate cancer, in particular when treated with androgen deprivation therapy, a milestone in its treatment. Systemic treatments for prostate cancer, especially with the newest options, have improved the survival and quality of life of patients with respect to skeletal-related events; however, all patients should be evaluated for “bone health” and osteoporotic risk, both in the presence and in the absence of bone metastases. Treatment with bone-targeted therapies should be evaluated even in the absence of bone metastases, as described in special guidelines and according to a multidisciplinary evaluation.

Despite the introduction of novel therapeutic options, the prognosis of advanced endometrial cancer remains poor. In recent years, increasing attention has been directed toward the molecular characterization of endometrial cancer. However, data specifically focusing on advanced-stage disease are still limited. In our single-center, retrospective, exploratory study with a limited sample size, we analyzed 32 patients with advanced or recurrent endometrial cancer treated at the Modena Cancer Center. Comprehensive molecular profiling was performed to assess DNA mutations, copy number variations, and RNA expression. We characterized the molecular landscape of this cohort, evaluated selected genomic alterations across predefined clinical subgroups, and explored their association with overall survival. Consistent with previous reports, a high prevalence of PTEN and PIK3CA mutations were observed. Patients experiencing relapse more than six months after diagnosis were more likely to harbor CTNNB1 mutations. KRAS mutations were more frequently detected in younger patients and in those with endometrioid histology, whereas PPP2R1A and TP53 mutations were enriched in tumors with non-endometrioid histology. Notably, CTNNB1 mutations were associated with a favorable prognostic impact, while KRAS mutations correlated with poorer overall survival. Our findings underscore the need for further investigation into the molecular landscape of advanced endometrial cancer, particularly in the context of therapeutic implications. Combinatorial treatment strategies targeting specific molecular alterations, such as KRAS, in combination with other targeted agents or therapeutic approaches, warrant further exploration.
