OBJECTIVE: The purpose of the present study was to evaluate treatment outcomes and prognostic factors in cervical cancer patients with isolated para-aortic lymph node (PALN) metastases. We especially tried to evaluate PALN factors such as size, site and number. METHODS: From August 1994 to December 2009, 40 cervical cancer patients with isolated PALN node metastases at initial diagnosis were selected for analysis. Patients underwent both extended field external beam and intracavitary brachytherapy. Fourteen patients received 5-fluorouracil and cisplatin (FP) and 16 patients received weekly concurrent cisplatin. Information of PALN, such as size, site, and number, was founded before PALN radiotherapy. RESULTS: The median follow-up time after primary treatment was 28.5 months (range, 2 to 213 months). The 3-year overall and progression-free survival rate after primary treatment was 44.3% and 31.3%, respectively. In multivariate analysis including tumor stage, performance status, and chemotherapy, FP regimen concurrent chemoradiotherapy was more effective than radiotherapy alone (p=0.030). The 3-year progression-free survival rate was 41.9% and 11.1% in patients with PALN numbers of < or =1 and > or =2, respectively (p=0.008). The 3-year progression-free survival rate was 42.1% and 19.2% in patients with PALN size of <1.5 cm and > or =1.5 cm, respectively (p=0.031). CONCLUSION: The radiologic features of PALN, such as number or size, can be used to determine prognosis in PALN metastatic cervical cancer patients. Furthermore, FP regimen concurrent chemoradiotherapy was associated with better patient survival than radiotherapy alone. However, more studies are required to confirm possible different treatment outcomes between FP and weekly cisplatin regimens.

The emergence of brain organoids as a model system has been a tremendously exciting development in the field of neuroscience. Brain organoids are a gateway to exploring the intricacies of human-specific neurogenesis that have so far eluded the neuroscience community. Regardless, current culture methods have a long way to go in terms of accuracy and reproducibility. To perfectly mimic the human brain, we need to recapitulate the complex in vivo context of the human fetal brain and achieve mature neural circuitry with an intact cytoarchitecture. In this review, we explore the major challenges facing the current brain organoid systems, potential technical breakthroughs to advance brain organoid techniques up to levels similar to an in vivo human developing brain, and the future prospects of this technology.

BACKGROUND/OBJECTIVES:
Inflammatory responses are key pathological factors in various canine diseases, making the control of inflammatory responses vital for canine health.This study examined the anti-inflammatory effects of rutin on DH82 cells, a type of canine macrophage, against lipopolysaccharide (LPS)-induced inflammatory responses.MATERIALS/METHODS: The inflammatory in vitro experimental model was established by stimulating canine macrophage DH82 cells with LPS. To evaluate the inflammationpreventative effects of rutin, analyses were conducted using enzyme-linked immunosorbent assay, western blot, and real-time quantitative reverse transcription polymerase chain reaction.
RESULTS:
Rutin inhibited the LPS-induced increase in the protein and gene levels of proinflammatory cytokines (interleukin [IL]-1β, IL-6, tumor necrosis factor-α), while antiinflammatory cytokines (IL-10, transforming growth factor-β1) levels remained unchanged.Furthermore, rutin suppressed the LPS-induced activation of phosphorylated extracellular signal-regulated kinase, Jun N-terminal kinase, inhibitor of nuclear factor kappa B, and nuclear factor kappa B (NF-κB) in DH82 cells.
CONCLUSION
Rutin exerts anti-inflammatory effects by inhibiting the mitogen-activated protein kinase-NF-κB signaling pathway and reducing the production of pro-inflammatory cytokines in DH82 cells.

Gangliocytic paraganglioma is an uncommon tumor of digestive system that is usually found in the second portion of duodenum. It is generally considered benign tumor, although few reports of local recurrences and regional lymph node metastases have been made. Gangliocytic paraganglioma is characterized by its histologic pattern including ganglion cells, spindle cells and epithelioid cells. Heterotopic pancreas, also known as ectopic pancreas, is a pancreatic tissue appeared outside of its normal location lacking anatomic or vascular connection with the pancreas. In duodenum, it is a relatively unusual lesion that may be found incidentally during surgery or endoscopy. We present a case of 39-year-old woman with gangliocytic paraganglioma combined with heterotopic pancreas in the ampulla of Vater successfully treated by endoscopic resection.

BACKGROUND: Isolated myeloid sarcoma (MS) is a rare extramedullary tumor mass composed of malignant myeloid precursor cells without any evidence of leukemia in the peripheral blood and bone marrow. We describe the clinical characteristics and outcomes of patients diagnosed with isolated MS at our institution. METHODS: We retrospectively reviewed 9 of 497 acute myeloid leukemia (AML) patients (1.8%) with isolated MS. Isolated MS patients were divided into 2 groups according to the first-line treatment strategy: systemic treatment only (S) or local treatment with or without systemic treatment (LS). RESULTS: The most common site of MS occurrence was the head and neck area (N=4, 44.4%), followed by the anterior mediastinum (N=2, 22.2%) and the gastrointestinal tract (N=2, 22.2%). The tumors of 4 patients (44.4%) eventually evolved to AML, in a median time of 13.4 months (range, 2.4–20.1 mo). The number of patients achieving complete remission after first-line treatment was higher in the LS group (N=5, 83.3%) than in the S group (N=1, 33.3%) (P =0.226). All patients in the LS group survived, but those in the S group died (P=0.012). CONCLUSION: Accurate and rapid diagnosis using various modalities and the early initiation of intensive combined treatment may be the optimal strategies to reduce the risk of isolated MS subsequently evolving to AML. To fully understand the characteristics of isolated MS, a larger number of patients from a multinational study is necessary.
