There is no literature that mainly searched for rectal neuroendocrine tumor (rNET) using transanal minimal invasive surgery (TAMIS). We report our clinical experiences of TAMIS for rectal neuroendocrine tumors to evaluate the feasibility and safety. Between December 2010 and March 2020, the 25 consecutive patients with rectal neoplasma underwent the TAMIS procedure performed by single laparoscopic surgeon at the two hospitals. Of these, ten patients with rectal neuroendocrine tumors were reviewe...

Abstract null null Background null Transarterial chemoembolisation (TACE) is a treatment option for hepatocellular carcinoma (HCC), but the optimum agent for TACE remains unclear. We compared the efficacy of TACE with cisplatin versus with epirubicin in patients with unresectable HCC. null null null Methods null This multicentre, randomised, phase 2/3 trial was performed at 21 hospitals in Japan. Patients with liver-confined HCC, performance status 0–2, and Child-Pugh class A/B were randomised t...

OBJECTIVE: To propose an algorithm for resecting hepatocellular carcinoma (HCC) in the caudate lobe. BACKGROUND: Owing to a deep location, resection of HCC originating in the caudate lobe is challenging, but a plausible guideline enabling safe, curable resection remains unknown. METHODS: We developed an algorithm based on sublocation or size of the tumor and liver function to guide the optimal procedure for resecting HCC in the caudate lobe, consisting of 3 portions (Spiegel, process, and caval)...

In the 21st Nationwide Follow-up Survey of Primary Liver Cancer in Japan, data from 22,134 new patients and 41,956 previously followed patients were compiled from 546 institutions over a 2-year period from 1 January 2010 to 31 December 2011. Basic statistics compiled for patients newly registered in the 21st survey were cause of death, past medical history, clinical diagnosis, imaging diagnosis, treatment-related factors, pathological diagnosis, recurrence status, and autopsy findings. Compared ...

Aim We reviewed the data of a nationwide follow-up survey to determine the impact of hepatitis C virus (HCV) infection on the outcomes of hepatectomy for intrahepatic cholangiocarcinoma (ICC) of the mass-forming (MF) type and combined mass-forming and periductal infiltrating (MF+PI) types. Methods In total, 956 patients with ICC who underwent curative hepatic resection were included in this cohort study, and patients were classified according to virus status. Patients were classified according t...

Abstract Background Although liver resection is the only potentially curative treatment for colorectal liver metastases, recurrence is frequent. We previously published the early results of a randomized controlled phase 3 trial showing that adjuvant therapy with uracil-tegafur and leucovorin significantly prolongs recurrence-free survival. This study sought to elucidate the impact of adjuvant chemotherapy on patient survival after an additional follow-up period, building upon the results of our ...

The surgical indications for liver metastasis from bile duct cancer remain contentious, because surgery is generally thought unlikely to improve survival. However, recent reports show that long-term survival has been achieved with liver resection of metastasis from recurrent bile duct cancer in selected patients. Liver resection for liver metastasis from bile duct cancer was proposed only when the following criteria were met: liver-only metastasis, a solitary tumor, and no increase in the number...
