BACKGROUND Circulating tumor cells in the blood were frequently detected by reverse transcription-polymerase chain reaction during operation in patients with biliary-pancreatic cancer. We investigated the relationship between circulating tumor cells during operation and hematogenous metastases. METHODS Blood samples from 67 patients with(More)
Invariant chain (Ii) is a chaperone molecule that inhibits the binding of endogenous antigens to HLA class II. The tumor cell with overexpressed Ii chain is thought to escape attacking cytotoxic lymphocytes by suppressing the host immune. However, the relationship between Ii expression by the tumor and clinicopathological factors in gastric cancer remains(More)
BACKGROUND We have evaluated the safety and feasibility of combining median-to-lateral and anterior-to-median (MLAM) approaches to perform laparoscopic complete mesocolic excision (CME) with radical lymph node dissection along the gastrocolic trunk of Henle (GTH) for right hemicolon cancer. PATIENTS AND METHODS We retrospectively analyzed data obtained(More)
BACKGROUND AND AIM We investigated the clinical benefits of salvage gastrectomy for stage IV gastric cancer patients whose distant lesions showed complete response after chemotherapy. METHODS We enrolled 18 stage IV gastric cancer patients whose distant metastases had disappeared or were controlled by a combination of biweekly paclitaxel (PTX) and S-1.(More)
BACKGROUND The authors hypothesized that circulating tumor cells (CTCs) in patients with gastric cancer are associated with prognosis and disease recurrence. In this study, they evaluated CTCs in gastric cancer and clarified the clinical impact of CTCs. METHODS In total, 265 consecutive patients with gastric cancer were enrolled. Fourteen patients were(More)
BACKGROUND Natural killer (NK) cells are a group of effector cells that act nonspecifically against tumor cells. The correlation between intratumoral NK cell infiltration and clinicopathologic features remains unclear. METHODS The authors selected 146 patients with gastric carcinoma who underwent gastrectomy at Kagoshima University Hospital between(More)
PURPOSE The treatment of early breast cancer using breast-conserving therapy commonly ensures local control and acceptable cosmetic results. We herein report a useful technique, including the use of a thoracodorsal adipofascial cutaneous flap for reconstructing defects in the outer quadrant area after partial mastectomy, which achieved excellent results.

Breast conservative therapy (BCT) as treatment for early breast cancer usually ensures local control and acceptable cosmetic results. We describe a new technique of using an inframammary adipofascial flap to reconstruct defects caused by lower-pole partial mastectomy, which achieved excellent results (Kijima et al. in Am J Surg 193:789-91 (1); Sakai et al.(More)
BACKGROUND Oncoplastic techniques, which combine the concepts of oncologic and plastic surgery, are becoming more common, especially in Western countries, however, only a few case reports have been published in Japan. We report the results of oncoplastic surgery for Japanese patients with early breast cancer in the lateral quadrant area. METHODS In eight(More)
We report a case of early breast cancer, which was treated successfully by oncoplastic surgery. A 65-year-old Japanese woman was referred to us for investigation of a grouped calcification on mammography of her left breast, detected during mass screening for breast cancer. No mass lesion was palpated, but we suspected that the grouped calcification seen on(More)
