Cardiophrenic angle lymph node metastasis from a fallopian primary tumor.

Isolated cardiophrenic angle node metastases are relatively rare, as are primary fallopian tube carcinomas. We describe a case of a cardiophrenic angle node metastasis from such a tumor, with no peritoneal involvement. A 52-year-old woman, who had been previously diagnosed with fallopian tube carcinoma, was referred with a right cardiophrenic angle mass. A thoracoscopic resection was performed. The pathological diagnosis was lymph node metastasis from the primary lesion.

Treatment of metastatic refractory colorectal cancer following regorafenib failure

At present, there is no set strategy for the treatment of patients with colorectal cancer subsequent to the failure of standard treatment, other than the use of regorafenib (RGR) and TAS-102. The best order in which to use these drugs, and their safety and efficacy in combination with other drugs, are currently under investigation. It has been reported that RGR has a resensitizing effect on tumors that have previously failed to respond to anticancer drugs; this makes it a promising salvage therapy for colorectal cancer. The present report describes the results of a retrospective study on 17 patients with metastatic colorectal cancer who received RGR treatment following the failure of standard therapy. Following RGR failure, 71% of the patients were fit for further anticancer treatment, and these patients survived longer than those who did not receive further treatment. Furthermore, this intervention did not shorten the period of best supportive care. As a considerable number patients were fit for further anticancer therapy after RGR treatment, which resulted in prolonged survival without shortening the period of best supportive care, it may be beneficial for future research to focus on finding the optimal time at which to switch from RGR to further anticancer therapy.
