The Glasgow Prognostic Score (GPS) has been shown to be associated with survival rates in patients with advanced cancer. The present study aimed to compare the GPS with the Eastern Cooperative Oncology Group Performance Status (ECOG PS) in patients with gastric cancer with peritoneal seeding. For the investigation, a total of 384 gastric patients with peritoneal metastasis were retrospectively analyzed. Patients with elevated C-reactive protein (CRP; >10 mg/l) and hypoalbuminemia (<35 mg/l) were assigned a score of 2...

BACKGROUND: Intraperitoneal administration of paclitaxel had been considered a promising option to treat peritoneal metastasis, the most frequent pattern of recurrence in gastric cancer after D2 gastrectomy, but its safety and efficacy after gastrectomy had not been fully explored. METHODS: A phase II randomized comparison of postoperative intraperitoneal (IP) vs. intravenous (IV) paclitaxel was conducted. Patients with resectable gastric linitis plastica, cancer with minimal amount of peritoneal deposits (P1), or cancer positive for the peritoneal washing cytology (CY1) were eligible...

The advent of disease evaluation by means of multi-slice spiral computed tomography (MSCT) and magnetic resonance imaging (MRI) represents a continually emerging role in the evaluation of various diseases; however, its role is yet to be adequately defined. Thus, the aim of the study was to compare the diagnostic value of MSCT and MRI in the diagnosis of peritoneal metastasis in primary ovarian carcinoma. Between January 2013 and December 2015, MSCT or MRI data were collected from 42 patients who had been previously diagnosed with peritoneal metastasis of ovarian carcinoma at the First Affiliated Hospital of Kunming Medical University...

BACKGROUND: Curative surgery of synchronous peritoneal metastases (PM) and colorectal liver metastases (LM) has been recently investigated as feasible option. When synchronous peritoneal and liver resection is not achievable, the sequence of the surgery remains unknown. Our hypothesis was that liver resection (LR) promotes peritoneal growth resulting in a non-resectable PM. We sought to analyse the effects of major LR and liver regeneration after hepatectomy in a murine model of PM and the associated angiogenesis...

The patient is a 42-year-old woman with metastatic primary peritoneal carcinoma and known brain metastases, who subsequently developed cauda equina syndrome after presenting with ataxia, lower extremity weakness, and bowel and bladder incontinence secondary to leptomeningeal metastasis after treatment with neoadjuvant chemotherapy, surgical debulking, and adjuvant chemotherapy. Metastases to the central nervous system (CNS) and leptomeninges are rare events in epithelial ovarian and primary peritoneal carcinomas as these tumours do not have a predilection for the CNS...

The patient was a 66-year-old woman. An induration of approximately 15 mm in size that accompanied redness was palpable in the umbilical fossa. She did not respond to 1-month antibiotic treatment provided by the previous physician. For this reason, a biopsy of the site was performed with the possibility of neoplastic disease in mind, resulting in the detection of adenocarcinoma. Subsequent detailed whole-body examination revealed advanced gastric cancer and peritoneal dissemination, and the induration in the umbilical fossa was diagnosed as a direct infiltration from the peritoneal dissemination...

The prognostic significance of glandular differentiation in urothelial carcinoma (UC) is controversial, and thus far there is no established treatment strategy against metastasis of glandular component. We describe here a case of metastatic UC with glandular differentiation that had histological disappearance of adenocarcinoma components at autopsy after sequential chemotherapy with S-1 and cisplatin (CDDP) and with mFOLFOX6 (fluorouracil, oxaliplatin, and leucovorin) plus bevacizumab (mFOLFOX6+Bev). A 62-year-old Asian male was diagnosed with invasive UC with glandular differentiation (T2N0M0) by radical cystectomy and ileal conduit, and careful follow-up observation was made...

Endometriosis, although not malignant, has clinically demonstrated properties of invasiveness and metastasis. The pathogenesis of endometriosis, however, has not yet been elucidated. The immunological differences between endometriosis and malignant gynecologic tumors were analyzed by assessing C-type lectin receptors, which are associated with innate immunity, and immunoglobulin secretion, which is associated with B cell adaptive immunity, in the peritoneal fluid of these patients. Peritoneal fluid samples were obtained from 42 patients with benign masses (control group), 38 with endometriosis, and 43 with gynecologic (ovarian, uterine, and cervical) cancers...

We previously designed and synthesized dehydroxyepoxyquinomicin (DHMEQ) as an inhibitor of NF-κB based on the structure of microbial secondary metabolite epoxyquinomicin C. DHMEQ showed anti-inflammatory and anticancer activity in various in vivo disease models without toxicity. On the other hand, the process of cancer metastasis consists of cell detachment from the primary tumor, invasion, transportation by blood or lymphatic vessels, invasion, attachment, and formation of secondary tumor. Cell detachment from the primary tumor and subsequent invasion are considered to be early phases of metastasis, while tumor cell attachment to the tissue and secondary tumor formation the late phases...

Peritoneal metastasis (PM) following primary resection of colorectal cancer is common. The combined use of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy has significantly improved the survival outcome of patients with colorectal PM (CRPM). Diagnosing and treating early PM is essential as its extent is correlated with poorer outcomes. There are two novel therapies - second-look surgery and synchronous hyperthermic intraperitoneal chemotherapy - that are proposed to prophylactically treat or intervene early in the disease process to reduce the incidence and adverse outcomes associated with PM...

Intraperitoneal metastasis is a common occurrence and is usually involved in the poor prognosis of ovarian cancer. Its specific metastatic pattern implies that certain indispensable microenvironmental factors secreted in the peritoneal cavity can direct metastatic ovarian cancer cells to permissive niches for secondary lesion formation. However, the underlying molecular mechanisms are ill defined. Herein, we report that GRO-α and IL-8 are predominately upregulated in culture media derived from either normal or cancerous omenta and are associated with increased ovarian cancer aggressiveness...

Intra-abdominal metastasis (IAM) of central nervous system (CNS) tumors via ventriculoperitoneal shunt (VPS) is rare but has been previously reported (e.g., germinomas and medulloblastomas). However, there has been no previous report in the literature involving meningiomas. A case of primary rhabdoid meningioma with widespread intra-abdominal carcinomatosis after placement of a VPS in a 36-year-old man is described. The patient underwent preoperative angioembolization of the tumor, craniotomy, and surgical excision, followed by postoperative gamma knife radiosurgery...

The differentiation between a primary mucinous ovarian neoplasm and an extra-ovarian metastasis in the ovary is often challenging in the histopathologic practice. Among various ovarian metastases from the gastro-intestinal tract the low-grade appendiceal mucinous neoplasm (LAMN) is an important differential diagnosis to consider particularly in case of pseudomyxoma peritonei. A newly recognized marker in the routine diagnostic of a mucinous neoplasm in the ovary is SATB2 (Special AT-rich sequence-binding protein 2)...
