BRAF V600E-mutated Colorectal Neuroendocrine Carcinoma Effectively Treated with a Chemotherapy Protocol for BRAF-mutated Metastatic Colorectal Cancer.

Metastatic colorectal neuroendocrine carcinoma (NEC) is often treated using a chemotherapy protocol for small-cell lung cancer; however, the prognosis is extremely poor. A 55-year-old woman with BRAF V600E-mutated transverse colon NEC and liver metastases underwent colectomy followed by FOLFOXIRI plus bevacizumab. Consequently, the liver metastases markedly shrank.

Efficacy of minocycline hydrochloride aspiration sclerotherapy with additional monoethanolamine oleate aspiration sclerotherapy for symptomatic hepatic cysts.

Aim: Minocycline hydrochloride (MINO) aspiration sclerotherapy (AS) has been widely used for treating hepatic cysts (HC). However, cyst recurrence remains problematic. Information on monoethanolamine oleate (EO) AS, another effective HC treatment, is currently limited.

[A case of gastric cancer showing a durable response after the discontinuation of nivolumab due to the early onset of immune-related adverse events].

The Japanese guidelines for the treatment of gastric cancer recommend nivolumab as third-line chemotherapy for metastatic gastric cancer. We report a case of gastric cancer exhibiting a durable response after the discontinuation of nivolumab due to the early onset of immune-related adverse event (irAE). A 64-year-old man with advanced HER2-positive gastric cancer and distant lymph node metastasis received nivolumab as fourth-line therapy.

Intraoperative laser flowmetry reflects levels of cerebral blood flow during neurosurgical procedures.

Changes in cerebral blood flow (CBF) during craniotomies (mean 62.2 years, n = 31) were studied using a laser flowmeter (LFM) to evaluate the utility in CBF monitoring. A small flat probe was applied to the brain surface near the surgical field.

Changes in the cerebrocortical capillary network following venous sinus occlusion in cats.

Background: Although the important protective effect of venous collateral pathways in sinus occlusion on parenchymal injury has been demonstrated in previous works, the vascular response in the capillary microcirculation itself after cerebral venous occlusion has not been fully elucidated. We examined the morphology of the capillary network after venous occlusion by relating stereologic morphometric parameters to changes in local cerebral blood flow and the development of brain edema.

Methods: Experimental venous sinus occlusion was induced by injection of 0.
