Little is known about the immunological effect of neoadjuvant chemoradiotherapy (NACRT) in the tumor microenvironment of pancreatic ductal adenocarcinoma. The objective of this study was to examine the immunological modifications induced by NACRT in patients with pancreatic cancer. Fifty-two patients with pancreatic cancer who underwent surgical resection(More)
The aim of this study was to assess the efficacy of combined resection and reconstruction (CRR) of the hepatic artery (HA) in surgery for hilar cholangiocarcinoma (HC). Among 172 patients who underwent surgical resection for HC, the following three groups were defined according to the type of vascular reconstruction: VR(−) group, in which neither CRR of the(More)
We report 3 cases of long-term control achieved via S-1 monotherapy in elderly patients with advanced non-small-cell lung cancer. In case 1, a 75-year-old man clinically diagnosed with stage IIIA lung adenocarcinoma received S-1 as fourthline chemotherapy. PR was achieved, and PFS was 8 months. In case 2, a 78-year-old woman clinically diagnosed with stage(More)
We report the cases of 2 patients with clinical T4( cT4) esophageal cancer who achieved pathological complete response on treatment with neoadjuvant chemoradiation therapy. Case 1 involved a 68-year-old woman who was diagnosed as having cT4 advanced esophageal cancer( with involvement of the aorta and left pulmonary vein). Neoadjuvant chemoradiation therapy(More)
INTRODUCTION We employed a safe approach during laparoscopic splenectomy by first mobilizing the pancreatic tail and then dissecting the splenic vessels at the splenic hilum before mobilizing the spleen. MATERIALS AND SURGICAL TECHNIQUE Patients were placed in the lithotomy position, and only the upper body was twisted to the right side. Five trocars were(More)
We describe a new wound management technique using a soft dressing material to stabilize the areola skin graft and protect the nipple after nipple-areola reconstruction at the final stage of breast reconstruction. We introduced a center-fenestrated multilayered hydrocellular polyurethane foam dressing material that provides adequate pressure and retains a(More)
BACKGROUND Although surgical resection is the only curative strategy for pancreatic cancer, the prognosis of patients with pancreatic cancer remains poor. Recently, neoadjuvant treatment has been frequently employed as a promising treatment. Here, the mid-term results of neoadjuvant chemoradiotherapy(NACRT)using S-1, which has been performed in our hospital(More)
