Unravelling oligometastatic disease from the perspective of radiation and medical oncology. Part II: prostate cancer and colorectal cancer.

Oligometastatic disease (OMD) defines a status of cancer that is intermediate between localized and widely spread metastatic disease, and can be treated with curative intent. While imaging diagnostic tools have considerably improved in recent years, unidentified micrometastases can still escape from current detection techniques allowing disease to progress. The variety of OMD scenarios are mainly defined by the number of metastases, the biological and molecular tumour profiles, and the timing of the development of metastases. Increasing knowledge has contributed to the earlier and improved detection of OMD, underlining the importance of an early disease control. Based on increasing detection rates of OMD in the current real clinical practice and the lack of standardized evidence-based guidelines to treat this cancer status, a board of experts from the Spanish Societies of Radiation Oncology (SEOR) and Medical Oncology (SEOM) organized a series of sessions to update the current state-of-the-art on OMD from a multidisciplinary perspective, and to discuss how results from clinical studies may translate into promising treatment options. This experts' review series summarizes what is known and what it is pending clarification in the context of OMD in the scenarios of Non-Small Cell Lung Cancer and Breast Cancer (Part I), and Prostate Cancer and Colorectal Cancer (Part II), aiming to offer specialists a pragmatic framework that might contribute to the improved management of patients.

Post-Irradiation Morphea in Breast Cancer: An Uncommon Differential Diagnosis to Keep in Mind.

Breast cancer is the most common cancer in women of developed countries. Early stage diagnosis is followed, in many cases, of conservative surgery and local radiotherapy. This treatment reduces loco-regional recurrences but may be accompanied by local complications. Morphea of the breast is an uncommon skin condition and has been described after radiotherapy. The inflammatory stage of morphea can commonly be mistaken for a local recurrence or inflammation. We report the case of a 51-year-old woman with breast cancer who underwent a conservative surgery with postoperative chemo and radiotherapy. She developed a sclerodermiform plaque with a biopsy that showed histopathological changes consistent with morphea.
