Surgery has evolved as a mainstay of the management of ovarian cancer since evidence of the major benefit of complete surgery, i.e. achieving complete resection of the disease without visible macroscopic residue in a comprehensively explored abdominal cavity, has been made available. This objective may be difficult to complete in case of advanced ovarian cancer, as it requires the use of advanced techniques of peritoneal and visceral surgery, in the setting of adapted perioperative care, generally in institutions where the caseload is sufficient to ensure an appropriate surgical experience, and where specifically trained surgeons are available...

Women with ovarian cancer often undergo chemotherapy involving multiple agents. However, little is known about treatment-related central neurotoxicity in this population. The goal of this cross-sectional study was to assess brain structure and function and neurocognitive abilities in patients with ovarian cancer following first-line chemotherapy. Eighteen patients with ovarian, peritoneal and fallopian tube cancer and eighteen healthy controls matched for gender, age and education participated in the study...

Among advanced gastric cancer cases, peritoneal dissemination is a life-threatening mode of metastasis, and any strategy to control peritoneal metastasis will significantly improve treatment outcomes. Since intraperitoneal administration of anticancer drugs can induce an extremely high concentration of drugs in the peritoneal cavity, intraperitoneal chemotherapy would appear to be a reasonable and promising strategy to control the peritoneal dissemination. However, it has been reported in the past that intraperitoneal administration of mitomycin C or cisplatin resulted in no significant clinical effects against peritoneal metastasis of gastric cancer...

Near-infrared photoimmunotherapy (NIR-PIT) is a highly cell-selective cancer therapy based on an armed antibody conjugated with a phthalocyanine-based photo-absorber, IRDye700DX (IR700). NIR-PIT can quickly kill target cells that express specific proteins on the cellular membrane but only when the antibody-IR700 conjugate binds to the cell membrane and is then exposed to NIR light. NIR-PIT is highly selective based on the specificity of the antibody. Galactosyl serum albumin (GSA) is composed of albumin decorated with galactose molecules conjugated to the carboxyl groups of albumin...

Leptomeningeal metastasis (LM) is rarely observed in gynecologic cancers. As gadolinium-enhanced magnetic resonance imaging (Gd-MRI) is highly effective for diagnosing LM, the aim of this study is to describe the clinical behaviors and outcomes of LM patients who were diagnosed by Gd-MRI. After securing institutional review board approvals, we retrospectively reviewed patient records. Eight patients were found to have LM from gynecological malignancies. Primary tumors included three ovarian cancers, one tubal cancer, one peritoneal cancer, two endometrial cancers, and one cervical cancer...

Colorectal peritoneal carcinomatosis (CRPC) is a common systemic metastasis of intra-abdominal cancers. Intraperitoneal chemotherapy against CRPC is at present the preferred treatment. The aim of this study is to develop a novel hydrogel drug delivery system through the combination of 5-fluorouracil (5-FU) loaded polymeric micelles and cisplatin (DDP) in biodegradable thermosensitive chitosan (CS) hydrogel. The prepared CS hydrogel drug is a free-flowing solution at room temperature and forms a stationary gel at body temperature...

A 57-year-old woman had been diagnosed with sigmoid colon cancer at surgery for ovarian cancer, and underwent simultaneous radical resection. Because of the pathological diagnosis of sigmoid cancer with ovarian metastasis, adjuvant chemotherapy was scheduled, with Leucovorin(LV)25 mg. This was immediately followed with 5-fluorouracil(5-FU)500 mg, via a 2-hour systemic intravenous infusion daily for 5 consecutive days, with courses repeated at 5 weeks, followed by maintenance once every 1 or 2 weeks for 2 years...

: Epithelial ovarian cancer (EOC) cells metastasize within the peritoneal cavity and directly encounter human peritoneal mesothelial cells (HPMCs) as the initial step of metastasis. The contact between ovarian cancer cells and the single layer of mesothelial cells involves direct communications that modulate cancer progression but the mechanisms are unclear. One candidate mediating cell-cell communications are exosomes, 30-100 nm membrane vesicles of endocytic origin, through the cell-cell transfer of proteins, mRNAs, or microRNAs...

Malignancies of the uterus metastasize by direct invasion of neighboring structures, lymphatically or hematogenously. Endometrial and cervical cancers lymphatically spread to the pelvic and para-aortic lymph nodes. For endometrial cancer the depth of myometrial invasion, lymphosvascular space involvement (LVSI) and a microcystic, elongated and fragmented (MELF) glandular invasion pattern are predictors for lymph node metastases. Metastases to the pelvic lymph nodes occur in approximately 10 % of endometrial cancer patients and in 30 % of these cases the para-aortic lymph nodes are also involved...

BACKGROUND: Advanced head and neck squamous cell carcinomas frequently develop distant metastases to limited organs, including the lungs, bone, mediastinal lymph nodes, brain, and liver. Peritoneal carcinomatosis as an initial distant metastasis from hypopharyngeal squamous cell carcinoma is quite rare. CASE PRESENTATION: A 75-year-old man diagnosed with hypopharyngeal squamous cell carcinoma and his clinical stage was determined as T2N2cM0. Notably, the right retropharyngeal lymph node surrounded more than half of the right internal carotid artery...

INTRODUCTION: For carcinoma of the ampulla of Vater, lymph node metastasis around the abdominal aorta is an inoperable factor equivalent to distant metastasis, such as hepatic metastasis or peritoneal carcinomatosis, making the cancer unresectable. PRESENTATION OF CASE: A 53-year-old man was referred to our hospital and was diagnosed as having carcinoma of the ampulla of Vater with lymph node metastases around the abdominal aorta. Although only chemotherapy was initially scheduled, the chemotherapy was effective, and the metastases were dramatically reduced after 4 cycles of chemotherapy...

Chronic inflammatory conditions during peritoneal dialysis (PD)-treatment lead to the impairment of peritoneal tissue integrity. The resulting structural and functional reorganization of the peritoneal membrane diminishes ultrafiltration rate and thereby enhances mortality by limiting dialysis effectiveness over time. Tumour necrosis factor (TNF) and its receptors TNFR1 and TNFR2 are key players during inflammatory processes. To date, the role of TNFR1 in peritoneal tissue damage during PD-treatment is completely undefined...

OBJECTIVE: Association between cancer and systemic sclerosis (SSc) has been described. However, paraneoplastic SSc is not well known. The aim of this article is to describe cases of paraneoplastic systemic sclerosis and to compare them to other cases of the literature, to find characteristics that can make suspect a paraneoplastic mechanism when SSc is diagnosed. METHODS: We retrospectively analyzed patients, in our department who, over the last 15 years, presented with Raynaud's phenomenon with a diagnosis of SSc (including cancer during the period of SSc)...

Introduction. Gallbladder volvulus is a rare, potentially fatal condition unless diagnosed and treated early. Choledochal cysts are rare congenital malformations of the biliary tree predisposing to different pathologies and posing the risk of degradation into cholangiocarcinoma and gallbladder cancer. Dealing with both diseases at once has not been published yet in the literature. Presentation of Case. We report a case of gallbladder volvulus in an elderly female who happened to have a concomitant type I choledochal cyst...

Background. Pelvic inflammatory disease (PID) rarely results in diffuse ascites. Severe adhesive disease secondary to PID may lead to the formation of inclusion cysts and even pelvic peritoneal nodularity due to postinflammatory scarring and cause an elevation of serum CA-125 levels. The constellation of these findings may mimic an ovarian neoplasm. Case. We report a case of a 22-year-old female who presented with multiple pelvic cysts and diffuse ascites due to Chlamydia trachomatis infection. The initial gynecologic exam did not reveal obvious evidence of PID; however, a positive Chlamydia trachomatis test, pathologic findings, and the exclusion of other etiologies facilitated the diagnosis...
