PURPOSE: Calcitonin is the most sensitive tumor marker of medullary thyroid carcinoma (MTC) and a calcium stimulation test is used to improve this sensitivity. In Japan, the electrochemiluminescence immunoassay (ECLIA) is currently the only test performed to measure serum calcitonin. There is a gender difference in the reference value of serum calcitonin; however, a reference upper limit for use with ECLIA has been reported only for women, but not for men. METHODS: We conducted the calcium stimulation test using ECLIA in 21 men with non-medullary thyroid carcinoma (non-MTC), before and after total thyroidectomy...

PURPOSE: We evaluated the long-term outcomes of clinical stage IA non-small cell lung cancer (NSCLC) patients with combined pulmonary fibrosis and emphysema (CPFE) who underwent lobectomy. METHODS: We reviewed the chest computed tomography (CT) findings and divided the patients into normal, fibrosis, emphysema and CPFE groups. We evaluated the relationships among the CT findings, the clinicopathological findings and postoperative survival. RESULTS: The patients were classified into the following groups based on the preoperative chest CT findings: normal lung, n = 187; emphysema, n = 62; fibrosis, n = 8; and CPFE, n = 17...

Yasushi Yoshikawa, Shigeru Miyagawa, Koichi Toda, Atsuhiro Saito, Yasushi Sakata, Yoshiki Sawa
BACKGROUND AND PURPOSE: Despite promising experimental results, clinically, intramyocardial myoblast injection failed to reverse remodeling and it induced arrhythmogenicity. In contrast, scaffold-free skeletal muscle-derived cell (SC) sheets attenuated cardiac dysfunction and arrhythmogenicity via paracrine effects. We report the first clinical trial of SC sheet implantation (SCSI) conducted in four patients with dilated cardiomyopathy (DCM) supported by a left ventricular assist device (LVAD)...

REVIEW
Kentaro Murakami, Hisahiro Matsubara
The "chronology of cancer" is a concept that describes the nature of cancers through the measure of time. The field extends from carcinogenesis to development, progression, and metastasis. Carcinogenesis is a multi-step process, which results from the accumulation of multiple genetic or epigenetic alterations. Various chronologies of gastrointestinal cancers have been reported for carcinogenesis caused by different risk factors. These chronologies are useful for developing cancer prevention strategies. The tumor growth rate is one of the most important factors in this field...

Atsushi Sano, Takuma Yotsumoto
The GIA Radial Reload is a surgical stapler with a curved cut line that is perpendicular to the direction of instrument insertion. We used the GIA Radial Reload in three cases of single-port thoracoscopic lung wedge resection. The operations were performed through a 3.0-4.5-cm incision. For the first stapler, we selected the GIA Radial Reload. The orientation of this device's cut line enabled us to easily cut the lung behind the lesion during single-port thoracoscopic surgery.

PURPOSE: Splenectomy is the standard therapy for medically refractory immune thrombocytopenia (ITP). Laparoscopic splenectomy (LS) has gained wide acceptance; however, the long-term outcomes of LS versus open splenectomy (OS) for patients with ITP remain unclear. METHODS: We analyzed, retrospectively, 32 patients who underwent splenectomy, as LS in 22 and OS in 10, for refractory ITP at our institute. Data were evaluated based on the American Society of Hematology 2011 evidence-based practice guidelines for ITP...

REVIEW
Suzuki Tomoaki
Multiple arterial grafting, including the use of the bilateral internal thoracic arteries (ITAs), has strong benefits on patient clinical outcomes after coronary artery bypass grafting (CABG) but is far from commonly accepted at present. We reviewed the previous randomized and leading observational studies and assembled an up-to-date profile on multiple arterial grafting. Many of the previous trials successfully showed the beneficial effects of arterial grafting after CABG. Although many of these were retrospective studies, the data presented, mostly from world-famous surgeons, show that multiple arterial grafting does have advantages with regard to the long-term patient outcome without increasing rates of early mortality or morbidity...

Preoperative biliary drainage (PBD) prior to pancreatoduodenectomy (PD) has gained popularity as bridge management to resolve jaundice, but its role is being challenged as it is thought to increase morbidity. To clarify the current recommendations for PBD prior to PD, we reviewed the literature, including all relevant articles published in English up until December, 2015. There is increasing evidence that PBD causes bile infection, which is related to the morbidity of infectious complications. Results of transhepatic drainage are poorer than those of endoscopic stenting, especially in an oncologic setting, although it is still unclear whether metallic stents are superior to nasobiliary drainage...

PURPOSE: The significance of sarcopenia after colorectal cancer (CRC) resection has only been discussed with relatively small samples or short follow-up periods. This study aimed to clarify the clinical significance of sarcopenia in a large-sample study. METHODS: We retrospectively analyzed the relationship between sarcopenia and clinical factors, surgical outcomes, and the survival in 494 patients who underwent CRC surgery between 2004 and 2013. Sarcopenia was defined based on the sex-specific skeletal muscle mass index measured by preoperative computed tomography...

Repeat hepatectomy is beneficial for selected patients with recurrence of liver malignancies. However, the operative procedure becomes technically demanding when the previous hepatectomy was complex, with hepatic veins and stump of portal pedicles exposed on the liver transection surface. We performed left hepatectomy after right paramedian sectoriectomy (RPMS) for three patients. Here, we describe our surgical technique and the postoperative outcomes achieved. This procedure allowed for safe adhesiolysis between the middle and right hepatic veins by following a fibrous plane...
