BACKGROUND Primary diffuse leptomeningeal gliomatosis is a rare neoplasm confined to the meninges without evidence of primary tumor in the brain or spinal cord parenchyma. Cerebrospinal fluid diversion via ventriculoperitoneal shunt may be used as a therapeutic modality. Herein, we describe the first report of cytologic findings of a case of this neoplasm with shunt-related peritoneal metastasi...

The present study presents a case of peritoneal malignant mesothelioma (PMM) following radiation therapy for cervical cancer. A 34-year-old Japanese woman, without asbestos exposure, was referred to the Department of Gynecologic Oncology, Saitama Medical University International Medical Center due to a cervical mass, and was diagnosed with cervical squamous cell carcinoma (SCC). The serum level...

that pleural exudate from patients with thoracic tumors may contain free tumor cells, some of which show mitotic figures. The study of the diagnostic significance of these cells has long been a part of exfoliative cytology (1, 10). How ever, our extensive search in the literature on cancer did not reveal any mention of experiments concerning the growth potentialities of free tumor cells floatin...

Because existing surgical and management methods can consistently cure only early-stage ovarian cancer, novel strategies for early detection are required. Silencing of tumor suppressor genes such as p16INK4a, VHL, and hMLH1 have established promoter hypermethylation as a common mechanism for tumor suppressor inactivation in human cancer and as a promising target for molecular detection in bodil...

OBJECTIVE To determine which computed tomography (CT) imaging features predict pleural malignancy in patients with advanced epithelial ovarian carcinoma (EOC) using video-assisted thoracic surgery (VATS), pathology, and cytology findings as the reference standard. METHODS This retrospective study included 44 patients with International Federation of Obstetrics and Gynecology (FIGO) stage III ...

Gastric cancer is the third most common cause of cancer death worldwide, although it is not in the top 10 causes of cancer death in Northern America. Due to clear differences in incidence, screening, risk factors, tumor biology, and treatment between gastric cancers from Eastern and Western countries, our treatment is primarily guided by trials from Western countries. Patients undergo an extens...

A 61-year-old never-smoking woman with stage IV lung adenocarcinoma with initially unknown epidermal growth factor receptor (EGFR) status, lung metastasis, pleural dissemination, and malignant pleural effusion in 2007 received 10 prior anti-cancer regimens including gefitinib as second- and ninth-line treatments, with minimal efficacy with gefitinib. EGFR mutation analysis performed in pleural ...

OBJECTIVE Diagnostic laparoscopy is recommended for the pretherapeutic staging of gastric cancer to detect any unexpected or unconfirmed intra-abdominal metastasis. The aim of this study was to evaluate the role and indications of diagnostic laparoscopy in the detection of intra-abdominal metastasis. METHODS Standard diagnostic laparoscopy with peritoneal cytology examination was performed pr...

BACKGROUND/AIM S-1, cisplatin, and docetaxel (DCS) constitute an effective regimen for gastric cancer. We conducted a retrospective cohort study of systemic DCS and a prospective phase I trial of intraperitoneal DCS in the preoperative setting for marginally resectable gastric cancer. PATIENTS AND METHODS Under the systemic regimen, patients received cisplatin (60 mg/m(2)) plus docetaxel (40 ...
