State of the art of the molecular hyperselection to guide treatment with anti-EGFR antibodies in RAS WT mCRC: implications for clinical practice and future perspectives.

Introduction: Adding monoclonal antibodies to chemotherapy drastically changed the landscape of advanced colorectal cancer. The prediction of benefit from anti-EGFR therapies is mainly based on the absence of mutations in RAS and BRAF genes, the primary tumor sidedness and microsatellite MSS/MSI status. Molecular hyperselection may optimize the outcome of patients receiving anti-EGFR while detecting additional resistance alterations, both in chemo-naïve and in chemo-refractory settings.

[The role of bisphosphonates of adjuvant therapy in breast cancer].

Breast cancer is the most common neoplasm in women. Bone is the most common site of metastatic spread from primary operable breast cancer, causing pain, fractures and hypercalcemia. This spread depends on the release of osteolytic substances by the cancer cells.

Hepatoid adenocarcinoma of the stomach - a different histology for not so different gastric adenocarcinoma: a case report.

Hepatoid adenocarcinoma is an extrahepatic tumor characterized by morphological similarities to hepatocellular carcinoma. Hepatoid adenocarcinoma of the stomach is a cancer with an extremely poor prognosis with few cases reported. Here, we describe a 75-year-old Spanish man referred to our hospital with a history of abdominal pain, general fatigue, anorexia and sickness.
