Dendritic cell maturation is induced by p53-armed oncolytic adenovirus via tumor-derived exosomes enhancing systemic antitumor immunity.

Dendritic cells (DCs) are crucial in cancer immunity, because they activate cytotoxic T cells by presenting tumor antigens. Recently, oncolytic virus therapy has been recognized as a systemic immune stimulator. We previously developed a telomerase-specific oncolytic adenovirus (OBP-301) and a p53-armed OBP-301 (OBP-702), demonstrating that these viruses strongly activate systemic antitumor immunity.

Long-term activation of anti-tumor immunity in pancreatic cancer by a p53-expressing telomerase-specific oncolytic adenovirus.

Background: Pancreatic cancer is an aggressive, immunologically "cold" tumor. Oncolytic virotherapy is a promising treatment to overcome this problem. We developed a telomerase-specific oncolytic adenovirus armed with p53 gene (OBP-702).

Correction: Time course change of the insulin requirements during the perioperative period in hepatectomy and pancreatectomy by using an artificial pancreas STG-55.

Local oncolytic adenovirotherapy produces an abscopal effect via tumor-derived extracellular vesicles.

Extracellular vesicles (EVs) play important roles in various intercellular communication processes. The abscopal effect is an interesting phenomenon in cancer treatment, in which immune activation is generally considered a main factor. We previously developed a telomerase-specific oncolytic adenovirus, Telomelysin (OBP-301), and occasionally observed therapeutic effects on distal tumors after local treatment in immunodeficient mice.

Effects of early endometriosis on IVF-ET outcomes.

There have been very few reports on the outcomes of in vitro fertilization and embryo transfer (IVF-ET) in women with stage I/II endometriosis. The objective of this study was to investigate IVF-ET outcomes in women with early-stage endometriosis. We enrolled 35 women less than 40 years with unexplained infertility who underwent IVF-ET into the study.

Comparison between the gonadotropin-releasing hormone antagonist protocol and the gonadotropin-releasing hormone agonist long protocol for controlled ovarian hyperstimulation in the first in vitro fertilization-embryo transfer cycle in an unspecified population of infertile couples.

Purpose: We aimed to compare the efficacy of a gonadotropin-releasing hormone (GnRH) antagonist protocol and a GnRH agonist long protocol used in the first in vitro fertilization-embryo transfer (IVF-ET) cycle in an unspecified population of infertile couples.

Methods: Fifty and 34 patients were treated with a GnRH agonist long protocol (agonist group) and GnRH antagonist protocol (antagonist group), respectively, in the first treatment cycle. The primary and secondary outcome measures were cumulative live birth rates after fresh and cryopreserved-thawed ETs and incidence of grades II and III ovarian hyperstimulation syndrome (OHSS), respectively.

Hysteroscopic tubal catheterization under laparoscopy for proximal tubal obstruction.

Purpose: The purpose of this study was to investigate the fertility outcomes of infertile patients having proximal tubal obstruction treated with hysteroscopic tubal catheterization (HCT) for recanalization under diagnostic laparoscopy.

Methods: From January 2000 to December 2008, diagnostic laparoscopy was used to assess the tubal status of 61 patients with unilateral or bilateral proximal tubal obstruction, as confirmed by hysterosalpingography. Among them, 35 patients with tubal obstruction confirmed by chromopertubation under laparoscopy subsequently underwent HCT.

Delayed pneumothorax after laparoscopic ovarian cystectomy.

Background: We describe a case that developed a delayed pneumothorax after laparoscopic surgery.

Case: A 40-year-old woman (BMI: 19.1) underwent a laparoscopic ovarian cystectomy.

Concurrent chemoradiation for locally advanced squamous cell carcinoma of the vagina: case series and literature review.

Background: We reviewed our experience with patients with primary squamous cell carcinoma of the vagina who received concurrent chemoradiation therapy (CCRT).

Methods: We retrospectively analyzed six patients (median age, 60 years) with squamous cell carcinoma of the vagina who underwent CCRT between 2002 and 2005 at the University of the Ryukyus Hospital. Two patients were in International Federation of Obstetricians and Gynecologists (FIGO) stage II, one in stage III, and three in stage IVA.

Laparoscopic marsupialization of pelvic lymphocele under transvaginal ultrasonographic guidance.

Lymphocyst formation is a common complication of pelvic lymphadenectomy. We treated a 54-year-old woman with lymphocele by laparoscopic marsupialization. She developed hydronephrosis as a result of retroperitoneal lymphocele after total abdominal hysterectomy and pelvic lymphadenectomy for endometrial cancer.

Squamous cell carcinoma arising in an ovarian mature cystic teratoma complicating pregnancy: a case report.

Background: The question of whether patients with pure stage I squamous cell carcinoma in a mature cystic teratoma (MCT) should undergo conservative surgery, or postoperative adjuvant treatment remains unresolved.

Case: A 33-year-old woman with a left ovarian cyst underwent laparoscopic cystectomy at 16 weeks of gestation. Histological examination confirmed squamous cell carcinoma arising in an MCT.
