FOLFOX activity in a rare case of metastatic colonic adenocarcinoma of the tongue: A case report

Abstract Background Adenocarcinomas of the oral cavity are rare neoplasms, and only four cases of primary colonic adenocarcinoma of the tongue have ever been described in literature. Very few information about chemotherapy sensitiveness of this type of neoplasia is available, with only one regimen that showed some activity in a metastatic patient. Case presentation We describe the case of a patient bearing a metastatic colonic adenocarcinoma of the tongue submitted to a first-line chemotherapy with oxaliplatin, 5-fluorouracil and folinic acid (FOLFOX regimen). After chemotherapy the patient obtained the complete disappearance of the primitive neoplasia located in the body of the tongue, and a tumor size reduction > 50% of liver and lung metastases. Conclusions This case demonstrated the activity of the combination of oxaliplatin and 5-fluorouracil in this very rare neoplasia. The FOLFOX regimen might be considered either in advanced and especially in the neoadjuvant setting, when the reduction of the primary tumor is highly needed

Immunotherapy for patients with advanced urothelial cancer: Current evidence and future perspectives

In recent years, immunotherapy has produced encouraging results in a rapidly increasing number of solid tumors. The responsiveness of bladder cancer to immunotherapy was first established in nonmuscle invasive disease in 1976 with intravesical instillations of bacillus Calmette-Guérin (BCG). Very recently immune checkpoint inhibitors demonstrated good activity and significant efficacy in metastatic disease. In particular the best results were obtained with programmed death-ligand-1 (PD-L1) and programmed death-1 (PD-1) inhibitors, but many other immune checkpoint inhibitors, including anti-cytotoxic T-lymphocyte-associated protein-4 (CTLA-4) antibodies, are currently under investigation in several trials. Simultaneously other therapeutic strategies which recruit an adaptive immune response against tumoral antigens or employ externally manipulated tumor infiltrating lymphocytes might change the natural history of bladder cancer in the near future. This review describes the rationale for the use of immunotherapy in bladder cancer and discusses recent and ongoing clinical trials with checkpoint inhibitors and other novel immunotherapy agents

Second-line treatment options in hepatocellular carcinoma

For many years, sorafenib has been the only approved systemic treatment for advanced hepatocellular carcinoma (HCC). For over a decade, randomized controlled trials exploring the efficacy of new drugs both in first- and second-line treatment have failed to prove any survival benefit. However, in the past few years, several advances have been made especially in pretreated patients; phase III trials of regorafenib, cabozantinib, and ramucirumab in patients with elevated α-fetoprotein have demonstrated efficacy in patients progressing after or intolerant to sorafenib. In addition, early phase I and II trials have shown promising results of immunotherapy alone or in combination with tyrosine-kinase inhibitors or monoclonal antibodies in the same setting of patients. In this review, we will discuss the evidence on second-line options for HCC, focusing on the latest results that are currently refining the treatment scenario
