Identification of sentinel lymph nodes by contrast-enhanced ultrasonography with Sonazoid in patients with breast cancer: a feasibility study in three hospitals.

The aim of this prospective study was to evaluate the feasibility of periareolar injection of the contrast agent Sonazoid (SNZ) followed by ultrasonography (US) for the identification of sentinel lymph node (SLN) in breast cancer patients with clinically negative node. Patients (n = 100) with T1-2N0M0 breast cancer received a periareolar injection of SNZ followed by US to identify contrast-enhanced SLN. Each contrast-enhanced SLN underwent fine needle aspiration cytology (FNAC) followed by SLN biopsy with a conventional method using blue dye and/or radiocolloid (B/R).

Association of GSTP1 methylation with aggressive phenotype in ER-positive breast cancer.

Aim: We investigated the association of glutathione S-transferase P1 (GSTP1) expression and methylation status with clinicopathological characteristics of estrogen receptor (ER)-positive breast cancers.

Materials And Methods: Primary ER-positive breast cancer patients (n=177, stage I-III) were retrospectively analyzed. A quantitative GSTP1 methylation assay was performed using DNA micro-dissected from formalin-fixed and paraffin-embedded (FFPE) breast surgical specimens and GSTP1 expression was examined immunohistochemically.

Significance of TP53 mutations determined by next-generation "deep" sequencing in prognosis of estrogen receptor-positive breast cancer.

Next-generation "deep" sequencing (NGS) was used for the mutational analysis of TP53, and a DNA microarray was used for the determination of the TP53 mutation-associated gene expression signature (TP53 GES) in 115 estrogen receptor (ER)-positive breast cancers. NGS detected 27 TP53 mutations, of which 20 were also detected by Sanger sequencing (SS) and seven were detected only by NGS. A significantly higher number of mutant alleles (33.

[A case of gastric cancer with liver metastasis had a good reaction to S-1/CDDP chemotherapy after S-1 chemotherapy was ineffective].

A woman in her sixties underwent total gastrectomy for gastric cancer. The pathological diagnosis was pT3, pN3, sH0, pCY0, sP0, sM0, fStage IV. Chemotherapy with S-1 was used after surgical treatment.

[Case report--a long-term surviving patient who received lymph node dissection of skip metastasis from rectosigmoid cancer to bilateral lateral lymph nodes].

Skip metastasis in colorectal cancer consists of about 10% of lymph node metastases. We report a rare long-term surviving patient of skip metastasis to lateral nodes after lymph node dissection. A forty-two years old female received anterior resection for advanced rectosigmoid cancer.

Pilot study of a combination of S-1 and paclitaxel for patients with peritoneal metastasis from gastric cancer.

Background: This pilot study was carried out to evaluate the efficacy of chemotherapy for patients with peritoneal dissemination from gastric cancer or positive lavage cytology diagnosed by staging laparoscopy.

Methods: Sixteen patients were enrolled. Paclitaxel was administered at 120 mg/m(2) on day 1 and S-1 was administered orally at 80 mg/m(2) for 14 consecutive days, followed by a 1-week rest, as one course.

[A case of epidermoid cyst in the intrapancreatic accessory spleen mimicking pancreatic malignant tumor].

We report a rare case of an epidermoid cyst in the intrapancreatic accessory spleen with producing CA19-9. A 42-year-old woman was referred to department of internal medicine of our hospital due to growing cystic lesion at the pancreatic tail. Laboratory tests on admission revealed a high serum CA19-9 (102.

[Outcome of therapy for type 4 gastric cancer with peritoneal metastasis--diagnosis by laparoscopy and effect of chemotherapy].

Unlabelled: Laparoscopy (st-lap) was performed for type 4 advanced gastric cancer cases, and chemotherapy was performed for P1 or CY1[ P(+)] cases. We present the results here.

Subjects: The subjects were type 4 advanced gastric cancer cases from October 2002 to December 2007 who underwent st-lap, as well as 7 P0 and CY0 [P(-)] cases (the operative group), and 18 P(+) cases which underwent chemotherapy (the chemotherapy group).

Surgical approach to left subclavian artery aneurysm in Marfan syndrome.

We present a case of left subclavian artery aneurysm in a 48-year-old man with Marfan syndrome. Aneurysmectomy and interposition with an artificial graft were successfully performed through an infraclavicular incision by dividing the clavicle at its midshaft. The clavicle bone was reconstructed with a steel plate, and the postoperative course was uneventful.

[A case of metastatic pancreatic cancer after combination chemotherapy with uracil-tegafur and gemcitabine].

We report a case of pancreas head cancer with liver metastasis treated with uracil-tegafur (UFT) and gemcitabine combined chemotherapy. A 66-year-old man was referred to our hospital for obstructive jaundice. We planned to perform a pancreatoduodenectomy, but a small nodule was found at laparotomy on the liver surface.

[A case of advanced sigmoid colon cancer performed resection of liver metastases after long-term control by S-1 and CPT-11 combination chemotherapy].

A 60-year-old man diagnosed as advanced sigmoid colon cancer was performed sigmoidectomy and D3 lymph node dissection. Intra-operative findings were SE, P0H1N4M (-), and Stage IV. One month after the operation, we started a combination chemotherapy using S-1 plus CPT-11 as one course for five weeks.

[Pilot study of neo-adjuvant chemotherapy involving intraperitoneal administration of paclitaxel and oral S-1 for patients with T3 gastric cancer].

The prognosis of patients with T3 gastric cancer is poor, even if a curative resection is performed. Novel combination neo-adjuvant chemotherapy has been introduced for T3 gastric cancer patients. This pilot study involving 5 patients was performed between December 2002 and March 2003.

[A long-term survival case of unresectable hepatohilar bile duct cancer treated with radiotherapy and hepatic arterial infusion chemotherapy ].

The patient, a 79-year-old woman, underwent distal gastrectomy for gastric cancer in November 2002. The lesion was judged to be T1 N0H0POM0 and fStage IA. A hepatohilar tumor was found 1 year after gastrectomy by CT scan.
