Comparison of Doxorubicin Plus Docetaxel Neoadjuvant Chemotherapy with Doxorubicin Plus Vinorelbine in Primary Breast Cancer
Purpose: This study was performed to compare the therapeutic efficacy and toxicity of doxorubicin plus docetaxel neoadjuvant chemotherapy (NC) with doxorubicin plus vinorelbine NC. Methods: Fifty-three patients underwent 4 cycles of NC consisted of intravenous injection of doxorubicin (50 mg/m 2) plus docetaxel (75 mg/m 2) administered every 3 weeks (AD), while 49 patients underwent 4 cycles of NC consisted of intravenous injection of doxorubicin (50 mg/m 2) and vinorelbine (25 mg/m 2) administered every 3 weeks (AN). Response rate and treatment-related toxicities were analyzed by administered chemotherapeutics. Response to NC was also analyzed according to clinicobiological characteristics of the primary tumors. Results: Clinical response was observed in 66 % with AN and 81.6 % with AD chemotherapy. A complete pathologic response (pCR) was confirmed in 6 patients (11.3%) with AN and in 7 patients (14.3%) with AD afte

Clinical outcome of cerebrospinal fluid shunts in patients with leptomeningeal carcinomatosis
Abstract Background Leptomeningeal carcinomatosis (LMC) is frequently associated with hydrocephalus, which quickly devastates the performance of the patient. Cerebrospinal fluid (CSF) shunt is a widely accepted treatment of choice, but the clinical outcomes in patients with LMC are not well studied. This study aimed to examine the efficacy of a CSF shunt in patients with LMC. Methods Seventy patients with LMC confirmed by cytology or magnetic resonance imaging (MRI) underwent ventriculoperitoneal (VP) or lumboperitoneal (LP) shunt surgery. We retrospectively analyzed the clinical characteristics of patients, symptom improvement after the shunt, rate of complications associated with the surgery, and overall survival. Results Fifty-five patients had systemic cancer as a preceding disease, including lung cancer (45), breast cancer (6), and others (4). Primary brain tumors were mainly glioma (7) and medulloblastoma (5). Fifty-one patients had VP shunt, and 19 had LP shunt. After surgery, preoperative symptoms âimprovedâ in 35 patients (50%) and were ânormalizedâ in 24 of those patients (34%). Shunt malfunction occurred in eight patients, and infection occurred in eight patients. Seventeen patients underwent revision due to infection, shunt malfunction, or over-drainage. There were no complications associated with peritoneal seeding during a median follow-up of 3.3âmonths after surgery. The median overall survival was 8.7Â months (95% confidence interval, 6.0â11.4) from LMC diagnosis and 4.1âmonths from shunt surgery. Conclusion VP or LP shunt is effective for patients with hydrocephalus from LMC in terms of symptom improvement and prolonging of overall survival with an acceptable rate of procedure-related complications. Trial registration This study was approved by the Institutional Review Board (IRB) of the National Cancer Center (retrospectively registered, NCC2018-0051)
BMET-13CSF PROFILES AS PROGNOSTIC MARKER OR PREDICTIVE MARKER FOR INTRAVENTRICULAR CHEMOTHERAPY IN PATIENTS WITH LEPTOMENINGEAL CARCINOMATOSIS FROM SOLID CANCERS
Guidelines for the Ligation of the Sigmoid or Transverse Sinus during Large Petroclival Meningioma Surgery
The authors present guidelines for the ligation of the transverse or sigmoid sinus during the surgical removal of petroclival meningiomas. The medical records and venograms of 14 patients with a petroclival meningioma requiring transverse or sigmoid sinus ligation treated in the Department of Neurosurgery, Seoul National University Hospital between 1986 and 1999 were reviewed. All patients successfully received a sinus trial clamping during the operation. The drainage pattern of the confluens of Herophili was classified into four types: Type A, confluens and equal on both transverse sinuses; Type B, confluens and nondominant transverse sinus on the tumor side; Type C, confluens and dominant transverse sinus on the tumor side; and Type D, unilateral transverse sinus only. Of the 14 cases, four were Type A, five were Type B, and two were Type C. There was no brain swelling after intraoperative test clamping of the sinus for more than 30 minutes. None of the cases developed postoperative complications related to the sinus ligation. Patients with Type A, B, or C drainage patterns were ideal candidates for sinus ligation, especially transverse sinus ligation, if the test clamping proved to be safe. The sinus was cut proximal to the superior petrosal sinus, distal to the vein of Labbé

Evaluation of Serum Neurofilament Light Chain and Glial Fibrillary Acidic Protein as Screening and Monitoring Biomarkers for Brain Metastases
We evaluated the potential serum neurofilament light chain (sNfL) and serum glial fibrillary acidic protein (sGFAP) roles in diagnosing and monitoring brain metastases (BMs). We included 70 patients with newly diagnosed BMs, 71 age- and cancer type-matched patients without BMs, and 67 healthy controls (HCs). We compared sNfL and sGFAP levels among the groups using a single-molecule array immunoassay. We prospectively followed 26 patients with BMs every 2â3 months by measuring sNfL and sGFAP levels and performing magnetic resonance imaging (MRI) scans. The sNfL and the sGFAP levels were higher in patients with BMs (medians: sNfL, 63.7 ”L; sGFAP, 819.5 pg/”L) than in those without BMs (sNfL, 13.3 ”L; sGFAP, 154 pg/”L; p < 0.001) and HCs (sNfL, 12.5 ”L; sGFAP, 135 pg/”L; p < 0.001). The sNfL and the sGFAP cutoff levels had a sensitivity and a specificity of 91%. The sGFAP cutoff level had a sensitivity of 91% and a specificity of 97%. The sNfL and the sGFAP levels were related to the BM size but not to the primary cancer type. After BM treatment, sNfL and sGFAP levels decreased with reduced BM lesions on MRI; however, they increased when BMs progressed. sNfL and sGFAP are potential biomarkers for BM screening in cancer patients
Risk Scoring System of Mortality and Prediction Model of Hospital Stay for Critically Ill Patients Receiving Parenteral Nutrition
Predicting the clinical progression of intensive care unit (ICU) patients is crucial for survival and prognosis. Therefore, this retrospective study aimed to develop the risk scoring system of mortality and the prediction model of ICU length of stay (LOS) among patients admitted to the ICU. Data from ICU patients aged at least 18 years who received parenteral nutrition support for â„50% of the daily calorie requirement from February 2014 to January 2018 were collected. In-hospital mortality and log-transformed LOS were analyzed by logistic regression and linear regression, respectively. For calculating risk scores, each coefficient was obtained based on regression model. Of 445 patients, 97 patients died in the ICU; the observed mortality rate was 21.8%. Using logistic regression analysis, APACHE II score (15â29: 1 point, 30 or higher: 2 points), qSOFA score â„ 2 (2 points), serum albumin level < 3.4 g/dL (1 point), and infectious or respiratory disease (1 point) were incorporated into risk scoring system for mortality; patients with 0, 1, 2â4, and 5â6 points had approximately 10%, 20%, 40%, and 65% risk of death. For LOS, linear regression analysis showed the following prediction equation: log(LOS) = 0.01 Ă (APACHE II) + 0.04 Ă (total bilirubin) â 0.09 Ă (admission diagnosis of gastrointestinal disease or injury, poisoning, or other external cause) + 0.970. Our study provides the mortality risk score and LOS prediction equation. It could help clinicians to identify those at risk and optimize ICU management
