BACKGROUND: Prior studies evaluating the impact of hysteroscopy on outcomes in endometrial cancer have predominantly evaluated type I tumors. We sought to evaluate whether hysteroscopy worsens prognosis in type II endometrial cancer. METHODS: A retrospective cohort analysis of 140 patients from two institutions with type II endometrial cancer was performed. Women who underwent either diagnostic hysteroscopy (HSC) or dilation and curettage (D&C) for cancer diagnosis from June 2001 until June 2010 were included...

BACKGROUND: HF10 is a highly attenuated type 1 herpes simplex virus (HSV) with proven effective oncolytic effect. Previous investigations have demonstrated that colon cancer mice model treated with HF10 not only had better survival but were also resistant to the reimplantation of the antitumor effect mediated by host antitumor immunity. Importantly, it has also been noted that in mice with antitumors implanted on both sides of the back, an injection of HF10 on only one side strongly restrains not only the injected antitumor but also the non-injected ones...

T2 (tumor invades perimuscular connective tissue; no extension beyond serosa or into liver) gallbladder cancer has generally been treated by S4aS5 subsegmentectomy (S4aS5 HR). We investigated the therapeutic effect of full-thickness cholecystectomy (FC) and gallbladder bed resection (GBR), in terms of tumor location and resection margin (distance from the tumor). At our department we employ the following protocol to determine the extent of resection needed to achieve R0 status: (1) A tumor located in the gallbladder fundus (Gf) or body (Gb) and only on the free peritoneal side was classified as P-type, for which full-thickness cholecystectomy and regional lymph node dissection were performed...

Gastrointestinal stromal tumors (GISTs) are the most common type of gastrointestinal mesenchymal tumors, although metastasis to the perigastric lymph nodes is relatively rare, compared with liver or peritoneal metastasis. In this report, we describe a case of stomach GIST with a solitary simultaneous metastasis in the left axillary lymph node. A 68-year-old man was diagnosed with a large upper-stomach GIST, and computed tomography and positron emission tomography revealed masses in the left axilla and right mediastinum...

BACKGROUND/OBJECTIVE: Positive carcinoembryonic antigen (CEA) messenger RNA (mRNA) in peritoneal lavage is associated with poor prognosis in patients with colon cancer. However, there are no reports about rectal cancer. Therefore we aimed to evaluate the frequency of positive CEA mRNA in peritoneal lavage and the significance of CEA mRNA in patients with low rectal cancer. METHODS: A total of 55 patients with low rectal cancer who received curative surgical resection were enrolled...

PURPOSE: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been proposed for controlling peritoneal seeding metastasis in some kinds of cancers, including those of colorectal origin, but their safety and oncological benefits are subjects of debate. We present our early experience with those procedures. METHODS: Data were retrospectively collected from all patients with peritoneal carcinomatosis (PC) and pseudomyxoma peritonei (PMP) treated using CRS and HIPEC at Yonsei Cancer Center between July 2014 and July 2015...

INTRODUCTION: A high cure rate for Wilms' tumor has been achieved using a multidisciplinary approach. The natural step forward is to offer the benefits of a minimally invasive technique for surgery, which is an obligatory part of treatment. Nevertheless, some authors resist using videolaparoscopic radical nephrectomy (VRN) because of concerns about reducing the cure index. METHODS: The present study included children with unilateral Wilms' tumor treated from December 2003 to December 2015 with neoadjuvant chemotherapy followed by VRN...

OBJECTIVE: The aim of the study was to confirm the noninferiority of mesorectal excision (ME) alone to ME with lateral lymph node dissection (LLND) in terms of efficacy. BACKGROUND: Lateral pelvic lymph node metastasis is occasionally found in clinical stage II or III lower rectal cancer, and ME with LLND is the standard procedure in Japan. ME alone, however, is the international standard surgical procedure for rectal cancer. METHODS: Eligibility criteria included histologically proven rectal cancer at clinical stage II/III; main lesion located in the rectum, with the lower margin below the peritoneal reflection; no lateral pelvic lymph node enlargement; Peformance Status of 0 or 1; and age 20 to 75 years...

Ovarian cancer is characterized by extensive peritoneal metastasis, with tumor spheres commonly found in the malignant ascites. This is associated with poor clinical outcomes and currently lacks effective treatment. Both the three-dimensional (3D) environment and the dynamic mechanical forces are very important factors in this metastatic cascade. However, traditional cell cultures fail to recapitulate this natural tumor microenvironment. Thus, in vivo-like models that can emulate the intraperitoneal environment are of obvious importance...

Here, we describe a patient with primary peritoneal carcinoma (PPC) who developed a late, solitary brain metastasis. It is a case of a 68-year-old female presented with a 1-month history of progressive gait disturbance who had undergone a surgical resection of PPC five years prior, followed by adjuvant chemotherapy. An MRI revealed a 4.6cm mass lesion in her right cerebellum. The patient underwent total removal of the tumour. The histopathology was consistent with a brain metastasis due to PPC. This condition is a rare malignancy of peritoneum, and only six cases of brain metastasis have been reported in PPC patients to date...

Gastric cancer (GC) is the most common epithelial malignancy worldwide. Basic transcription factor 3 (BTF3) plays a crucial role in the regulation of various biological processes. We designed experiments to investigate the molecular mechanism underlying the role of BTF3 in GC cell proliferation and metastasis. We confirmed that BTF3 expression was decreased in GC tissues and several GC cell lines. Lentivirus-mediated downregualtion of BTF3 reduced cell proliferation, induced S and G2/M cell cycle arrest, and increased apoptosis...

The reciprocal interplay of cancer cells and host cells is an indispensable prerequisite for tumor growth and progression. Cells of both the innate and adaptive immune system, in particular tumor-associated macrophages (TAMs) and T cells, as well as cancer-associated fibroblasts enter into a malicious liaison with tumor cells to create a tumor-promoting and immunosuppressive tumor microenvironment (TME). Ovarian cancer, the most lethal of all gynecological malignancies, is characterized by a unique TME that enables specific and efficient metastatic routes, impairs immune surveillance, and mediates therapy resistance...

BACKGROUND AND AIMS: Growing evidence suggests that microRNA plays an essential role in the development and metastasis of many tumors, including gastric cancer (GC). Expression of microRNA-203 (miR-203) has been reported to decrease in GC. In addition, overexpression of miR-203 inhibits grow of GC cells in vitro and in vivo. However, whether miR-203 affects cell migration and invasion of GC remains unclear. This study aimed to reveal the role of miR-203 on migration and invasion of GC, and its potential mechanisms...

PURPOSE: Human epidermal growth factor receptor 2 (HER2) is over-expressed in over 30% of ovarian cancer cases, playing an essential role in tumorigenesis and metastasis. Non-invasive imaging of HER2 is of great interest for physicians as a mean to better detect and monitor the progression of ovarian cancer. In this study, HER2 was assessed as a biomarker for ovarian cancer imaging using (64)Cu-labeled pertuzumab for immunoPET imaging. METHODS: HER2 expression and binding were examined in three ovarian cancer cell lines (SKOV3, OVCAR3, Caov3) using in vitro techniques, including western blot and saturation binding assays...

Advanced ovarian cancers are highly metastatic due to frequent peritoneal dissemination, resulting in dismal prognosis. Here we report the functions of cancer-derived extracellular vesicles (EVs), which are emerging as important mediators of tumour metastasis. The EVs from highly metastatic cells strongly induce metastatic behaviour in moderately metastatic tumours. Notably, the cancer EVs efficiently induce apoptotic cell death in human mesothelial cells in vitro and in vivo, thus resulting in the destruction of the peritoneal mesothelium barrier...
