A 49-year-old male with Ewing sarcoma and bone, pleural, lung and mediastinal lymph node metastasis was treated with cabozantinib after four lines of previous systemic treatments. He responded objectively and subjectively well for 8 months. In this heavily pretreated patient, the daily starting dose of 60 mg had to be reduced to 30 mg because of adverse events. We conclude that treatment with cabozantinib administered in further-line was active in this particular patient with metastatic Ewing sarcoma....

Background/Aim: The host's systemic inflammatory response is thought to affect the progression of cancer and the antitumor effects of chemotherapy. Meta-analyses have reported that the peripheral blood platelet-to-lymphocyte ratio (PLR) is a prognostic indicator of this effect. Therefore, we hypothesized that PLR may differ, depending on sentinel lymph node metastasis (SLNM) in patients diagnosed with cT1N0M0 breast cancer by preoperative imaging. This study investigated the ability of preoperative...

Pancreatic cancer is often diagnosed due to the patient seeking medical attention for abdominal pain. It is among the most painful cancers, with pain severity strongly correlating with prognosis. Perineural invasion is a prominent feature of pancreatic cancer and often the first route of metastasis resulting in neuropathic pain. While surgical pain is present, it is generally short-lived; chemo- and radio-therapy associated side effect pain is often longer lasting and more difficult to manage. Treatment-induced...
