To measure the toxic potential of asbestos fibers-a known cause of asbestosis, lung cancer, and malignant mesothelioma-asbestos minerals are generally first ground down to small fibers, but it is unknown whether the grinding condition itself changes the fiber toxicity. To evaluate this, we ground chrysotile ore with or without water for 5-30 min and quantified asbestos-induced reactive oxygen species generation in elicited murine peritoneal macrophages as an indicator of fiber toxicity. The toxicity of dry-ground fibers was higher than the toxicity of wet-ground fibers...

Management of peritoneal surface malignancies has gradually evolved by the introduction of cytoreductive surgery in combination with intraperitoneal chemotherapy applications. Recently, peritoneal metastases of intraabdominal solid organ tumors and primary peritoneal malignancies such as peritoneal mesothelioma are being treated with this new approach. Selection criteria are important to reduce morbidity and mortality rates of patients who will experience minimal or no benefit from these combined treatment modalities...

Diffuse malignant peritoneal mesothelioma (MPeM) is rare and arises from peritoneal serosal surfaces. Although it shares similar histomorphology with its counterpart, malignant pleural mesothelioma, etiologies, clinical courses, and therapies differ. Nuclear grading and level of mitoses have been correlated with prognosis in malignant pleural mesothelioma with epithelioid subtype. Whether nuclear grading and level of mitoses correlate with prognosis in MPeM is still unknown. Our study utilizes a 2 tier system incorporating nuclear features and level of the mitoses to stratify cases of MPeM with epithelioid subtype...

A wild-born, captive-reared, 14 yr old, primiparous female California sea lion Zalophus californianus presented for anorexia of 14 d duration and abdominal distention. Routine complete blood cell count revealed leukocytosis with a neutrophilia, and serum chemistry revealed hypoalbumenemia and hyponatremia. Treatment with broad spectrum antibiotics and non-steroidal anti-inflammatories were started, but the animal continued to decline. Abdominal radiographs revealed a mature mineralized fetal skull and spine in the caudal abdomen and abdominal ultrasound revealed ascites but could not confirm the fetus...

Introduction Peritoneal surface malignancies have long been regarded as incurable, however, they can be treated with cytoreductive surgery in addition to hyperthermic intraperitoneal chemotherapy. This approach is associated with an increase in morbidity and mortality, unless hyperhydration is provided in a timely manner. Methods Cisplatin (CDDP) is the most widely used chemotherapeutic agent. Plasma levels of cisplatin (CDDP), a widely used chemotherapeutic agent, were measured before, during, and after the procedure...

High-grade versions of appendiceal goblet cell carcinoids ('adenocarcinoma ex-goblet cell carcinoids') are poorly characterized. We herein document 77 examples. Tumors occurred predominantly in females (74%), mean age 55 years (29-84), most with disseminated abdominal (77% peritoneal, 58% gynecologic tract involvement) and stage IV (65%) disease. Many presented to gynecologic oncologists, and nine had a working diagnosis of ovarian carcinoma. Metastases to liver (n=3) and lung (n=1) were uncommon and none arose in adenomatous lesions...

Peritoneal carcinomatosis (ptc) represents advanced malignant disease and has generally been associated with a grim prognosis. Peritoneal surface malignancy is often the major source of morbidity and mortality; it is of major concern in cancer management. Although ptc is categorized as metastatic disease, it represents a special disease pattern considered to be a locoregional disease limited to the abdominal cavity. The combination of cytoreductive surgery (crs) and intraoperative hyperthermic intraperitoneal chemotherapy (hipec) has successfully been used as locoregional treatment for selected patients with ptc from gastric, colorectal, and ovarian cancer; with mesothelioma; and with pseudomyxoma peritonei...

Leiomyomatosis peritonealis disseminata (LPD) is a rare smooth muscle tumor, which is characterized by the dissemination of multiple smooth muscle-like nodules throughout the omental and peritoneal surfaces. The present report describes the case of a 33-year-old woman who had previously undergone laparoscopic myomectomy due to a bizarre leiomyoma. Five years after the initial operation, the patient was referred to our hospital with irregular episodes of right abdominal pain. As the presentation was highly suspicious of malignant uterine tumor metastasis or LPD, the patient subsequently underwent laparoscopic total hysterectomy, bilateral salpingo-oopherectomy, omental resection and excision of some of the disseminated nodules...

BACKGROUND: The value of 5-aminolevulinic acid (ALA) in fluorescence detection of peritoneal metastases and the underlying mechanisms were evaluated in patients with peritoneal surface malignancies. MATERIALS AND METHODS: Oral 5-ALA was administered at a concentration of 20 mg ⁄kg body weight with 50 ml of water 2 hours prior to surgery (n=115). The diagnostic value of 5-ALA based fluorescence production was evaluated following white light inspection during prior to cytoreductive surgery and hyperthermic intraperitoneal chemotherapy...

Intraperitoneal chemotherapy together with cytoreductive surgery is the standard of care for a number of peritoneal surface malignancies. However, this approach fails to maintain the complete response and disease recurs due to microscopic residual disease. Although safer than systemic chemotherapy regimens, locoregional treatment with chemotherapeutics can induce toxicity which is a major concern affecting the patient's treatment protocol and outcome. For an enhanced treatment efficacy, efforts should be made to maximize cytotoxic effects of chemotherapeutic agents on tumor cells while minimizing their toxic effects on host cells...

Macrophage infiltration promotes tumorigenesis. However, the macrophage infiltration regulatory molecules have not been fully determined. Nerve injury-induced protein 1 (ninjurin1) is a homophilic cell surface adhesion molecule that plays an important role in cell migration and attachment. Although ninjurin1 is believed to play a role in several malignancies, it is unclear whether ninjurin1 expression contributes to cancer progression. We used transgenic mice (tg mice) that overexpressed ninjurin1 on macrophages...

OBJECTIVE: To review our 25-year experience with hyperthermic intra-peritoneal chemotherapy (HIPEC). BACKGROUND: Combining cytoreductive surgery (CRS) and HIPEC as local treatments for peritoneal carcinomatosis (PC) was proposed 25 years ago. METHODS: A prospective database of all patients undergoing HIPEC for PC since 1989 was searched for clinicopathological data, 90-day morbidity and mortality, and survival. RESULTS: Among 1,125 HIPEC procedures, PC origin was colorectal (342; 30%), ovarian (271; 24%), pseudomyxoma peritonei (189; 17%), gastric (127; 11%), malignant mesothelioma (84; 8%), or other (112; 10%)...

OBJECTIVES: To evaluate and compare the ability of DW-MRI and CT to detect sites of peritoneal dissemination in gynecologic malignancies. The reproducibility of DW-MRI and CT interpretation between radiologists was also assessed. METHODS: Single institution prospective cohort study of women with suspected advanced gynecologic cancer who underwent surgical staging from 2010 to 2013. Participants underwent both DW-MRI and contrast-enhanced CT prior to surgery. Radiologists and surgeons were blinded, respectively, to surgical and DW-MRI results...

INTRODUCTION: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is an effective treatment for selected patients with peritoneal surface malignancies (PSM). Although it can have significant morbidity, perioperative mortality is low. Little is known about whether major complications after CRS/HIPEC have a lasting impact on patients' quality of life (QOL). METHODS: We retrospectively reviewed data from a prospectively collected database on patients treated with CRS/HIPEC for PSM (2011-2014)...

A woman in her 50s visited our hospital in February 2015 with a complaint of dull abdominal pain in the right lower quadrant. She had a medical history of appendectomy for appendicitis in her 20s. Computed tomography(CT)revealed a tumor 90 mm in diameter near the ileocecum. Elective surgery was planned under the suspicion of gastrointestinal tumor, malignant lymphoma, or ileal cancer. She was emergently hospitalized 1 day earlier than scheduled because of high fever and severe abdominal pain. CT revealed that the tumor had increased to 120 mm in diameter without free air...

The introduction of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has led to an improvement in the survival of select patients with peritoneal surface malignancies (PSM). However, it is important to carefully identify patients who will benefit from this procedure and to avoid an unnecessary laparotomy in those who will not. The currently available imaging modalities are unable to accurately predict the peritoneal cancer index (PCI) score or the completeness of cytoreduction...
