Background:
Bulky or multiple lymph node (LN) metastases are associated with poor prognosis in cervical cancer, and the size or number of LN metastases is not yet reflected in the staging system and therapeutic strategy. Although the therapeutic effects of surgical resection of bulky LNs before standard treatment have been reported in several retrospective studies, wellplanned randomized clinical studies are lacking. Therefore, the aim of the Korean Gynecologic Oncology Group (KGOG) 1047/DEBULK trial is to investigate whether the debulking surgery of bulky or multiple LNs prior to concurrent chemoradiation therapy (CCRT) improves the survival rate of patients with cervical cancer IIICr diagnosed by imaging tests.
Methods
The KGOG 1047/DEBULK trial is a phase III, multicenter, randomized clinical trial involving patients with bulky or multiple LN metastases in cervical cancer IIICr. This study will include patients with a short-axis diameter of a pelvic or para-aortic LN ≥2 cm or ≥3 LNs with a short-axis diameter ≥1 cm and for whom CCRT is planned. The treatment arms will be randomly allocated in a 1:1 ratio to either receive CCRT (control arm) or undergo surgical debulking of bulky or multiple LNs before CCRT (experimental arm). CCRT consists of extended-field external beam radiotherapy/pelvic radiotherapy, brachytherapy and LN boost, and weekly chemotherapy with cisplatin (40 mg/m 2 ), 4–6 times administered intravenously.The primary endpoint will be 3-year progression-free survival rate. The secondary endpoints will be 3-year overall survival rate, treatment-related complications, and accuracy of radiological diagnosis of bulky or multiple LNs.

Background:
Sentinel lymph node (SLN) mapping has been suggested as an alternative surgical technique to full lymphadenectomy for early-stage endometrial cancer. However, the survival outcomes of SLN mapping compared with lymphadenectomy have not been established via a prospective study.
Methods
A multi-center, single-blind, randomized controlled trial has been designed to determine the prognostic value of SLN mapping alone compared with conventional lymphadenectomy for patients with clinical stage I-II endometrial cancer. Eligible participants will be randomly assigned in a 1:1 ratio between the group to undergo SLN mapping using indocyanine green and the conventional lymph node dissection group. A high-risk group will undergo a 2-step SLN mapping procedure. The primary endpoint is the 3-year disease-free survival (DFS). The secondary endpoints are 3-year overall survival (OS), 5-year DFS, 5-year OS after surgery, pattern of recurrence, immediate surgical outcomes, success rate of SLN mapping, postoperative lymph-related complications, postoperative quality of life, and postoperative cost effectiveness. The role of pathologic ultrastaging of SLNs will also be assessed.

Objectives:
The aims of this study were to assess the feasibility of single-port laparoscopic surgical staging (SPLS) in early ovarian cancer and to compare the surgical outcomes of SPLS with those of staging laparotomy.
Methods:
Between January 2014 and December 2018, 40 patients underwent SPLS and 41 patients underwent staging laparotomy at Yonsei Cancer Center. The patients were diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stage I ovarian cancer. Variables such as patient age, body mass index (BMI), tumor size, FIGO stage, and perioperative surgical outcomes and survival outcomes of SPLS and laparotomy were compared.
Results:
The total operation time was similar between the 2 groups (SPLS: 201.4 vs. laparotomy: 203.0 minutes, P=0.806). The median tumor diameters in the SPLS and laparotomy groups were 11.0 (2.5–28 cm) and 15.4 (6–40 cm), respectively (P=0.001). The SPLS group had lower tumor spillage rate (5.0% vs. 19.5%, P=0.047), less intraoperative blood loss (102.0 vs. 371.5 mL, P<0.001), less postoperative pain, and shorter postoperative hospital stay (5 vs. 9.5 days, P<0.001). The intraoperative major complication rate was similar between groups (2.5% vs. 4.9%, P=0.571). There was no significant difference in progression-free survival between the 2 groups (P=0.945). There were no deaths in either group.
Conclusion
SPLS is feasible in early ovarian cancer and has better perioperative surgical outcomes, in some aspects, than staging laparotomy without compromising survival outcomes. SPLS could be performed in patients suspected to have early ovarian cancer.

Baicalein, a natural flavonoid obtained from the rhizome of Scutellaria baicalensis Georgi, has been reported to have anticancer activities in several human cancer cell lines. However, its antimetastatic effects and associated mechanisms in melanoma cells have not been extensively studied. The current study examined the effects of baicalein on cell motility and anti-invasive activity using mouse melanoma B16F10 cells. Within the noncytotoxic concentration range, baicalein significantly inhibited the cell motility and invasiveness of B16F10 cells in a concentration-dependent manner. Baicalein also reduced the activity and expression of matrix metalloproteinase (MMP)-2 and -9; however, the levels of tissue inhibitor of metalloproteinase-1 and -2 were concomitantly increased. The inhibitory effects of baicalein on cell motility and invasiveness were found to be associated with its tightening of tight junction (TJ), which was demonstrated by an increase in transepithelial electrical resistance and downregulation of the claudin family of proteins. Additionally, treatment with baicalein markedly reduced the expression levels of lipopolysaccharide-induced phosphorylated Akt and the invasive activity in B16F10 cells. Taken together, these results suggest that baicalein inhibits B16F10 melanoma cell migration and invasion by reducing the expression of MMPs and tightening TJ through the suppression of claudin expression, possibly in association with a suppression of the phosphoinositide 3-kinase/Akt signaling pathway.

A high degree of sensitization to human leukocyte antigen requires more intensive induction therapy; however, this increases vulnerability to opportunistic infections following kidney transplantation. Although recent studies have suggested that combined induction therapy with antithymocyte globulin and rituximab would be more effective in highly sensitized kidney recipients, we experienced a case of near-fatal invasive pulmonary aspergillosis 2 months after combined induction and early rejection therapy for graft dysfunction. Fortunately, the patient recovered with intensive antifungal treatment and lung lobectomy for a necrotic cavity. Antifungal prophylaxis should be considered in cases undergoing intensive induction therapy.

Journal of Clinical Neurology 2016;12(4):381-392
No disease-modifying therapies (DMT) for neurodegenerative diseases (NDs) have been established, particularly for Alzheimer's disease (AD) and Parkinson's disease (PD). It is unclear why candidate drugs that successfully demonstrate therapeutic effects in animal models fail to show disease-modifying effects in clinical trials. To overcome this hurdle, patients with homogeneous pathologies should be detected as early as possible. The early detection of AD patients using sufficiently tested biomarkers could demonstrate the potential usefulness of combining biomarkers with clinical measures as a diagnostic tool. Cerebrospinal fluid (CSF) biomarkers for NDs are being incorporated in clinical trials designed with the aim of detecting patients earlier, evaluating target engagement, collecting homogeneous patients, facilitating prevention trials, and testing the potential of surrogate markers relative to clinical measures. In this review we summarize the latest information on CSF biomarkers in NDs, particularly AD and PD, and their use in clinical trials. The large number of issues related to CSF biomarker measurements and applications has resulted in relatively few clinical trials on CSF biomarkers being conducted. However, the available CSF biomarker data obtained in clinical trials support the advantages of incorporating CSF biomarkers in clinical trials, even though the data have mostly been obtained in AD trials. We describe the current issues with and ongoing efforts for the use of CSF biomarkers in clinical trials and the plans to harness CSF biomarkers for the development of DMT and clinical routines. This effort requires nationwide, global, and multidisciplinary efforts in academia, industry, and regulatory agencies to facilitate a new era.

A 77-year-old woman was admitted to a local clinic for altered consciousness and presented with a suspected basal ganglion hemorrhage detected on brain computed tomography. The patient was stuporous, but her vital signs were stable. Her initial blood glucose was 607 mg/dL, and a hyperdense lesion was found in the right basal ganglion on brain computed tomography. T1-weighted magnetic resonance imaging revealed high signal intensity in the right basal ganglion. Electroencephalography showed no seizure activity. The patient was treated with a fluid infusion, and serum glucose level was controlled with insulin. The patient gradually recovered consciousness and was alert within 24 hours as serum glucose level normalized. The basal ganglion lesion caused by hyperglycemia was not accompanied by involuntary limb movement. This is the first report of a patient presenting with decreased consciousness and typical neural radiographic changes associated with nonketotic hyperglycemia but without movement abnormalities.
