RESUMEN
OBJECTIVE: To assess the clinical implications of cryoanalgesia for pain management in children undergoing minimally invasive repair of pectus excavatum (MIRPE). BACKGROUND: MIRPE entails significant pain management challenges, often requiring high postoperative opioid use. Cryoanalgesia, which blocks pain signals by temporarily ablating intercostal nerves, has been recently utilized as an analgesic adjunct. We hypothesized that the use of cryoanalgesia during MIRPE would decrease postoperative opioid use and length of stay (LOS). MATERIALS AND METHODS: A multicenter retrospective cohort study of 20 US children's hospitals was conducted of children (age below 18 years) undergoing MIRPE from January 1, 2014, to August 1, 2019. Differences in total postoperative, inpatient, oral morphine equivalents per kilogram, and 30-day LOS between patients who received cryoanalgesia versus those who did not were assessed using bivariate and multivariable analysis. P value <0.05 is considered significant. RESULTS: Of 898 patients, 136 (15%) received cryoanalgesia. Groups were similar by age, sex, body mass index, comorbidities, and Haller index. Receipt of cryoanalgesia was associated with lower oral morphine equivalents per kilogram (risk ratio=0.43, 95% confidence interval: 0.33-0.57) and a shorter LOS (risk ratio=0.66, 95% confidence interval: 0.50-0.87). Complications were similar between groups (29.8% vs 22.1, P =0.07), including a similar rate of emergency department visit, readmission, and/or reoperation. CONCLUSIONS: Use of cryoanalgesia during MIRPE appears to be effective in lowering postoperative opioid requirements and LOS without increasing complication rates. With the exception of preoperative gabapentin, other adjuncts appear to increase and/or be ineffective at reducing opioid utilization. Cryoanalgesia should be considered for patients undergoing this surgery.

INTRODUCTION: Given the negative clinical effects opiates can have, the search for alternative forms of analgesia to treat post-operative pain continues. We implemented an opiate reduction strategy using standing intravenous (IV) acetaminophen for infants aged less than 1 y who underwent abdominal or anorectal surgery and recovered on the acute care floor. MATERIALS AND METHODS: Infants were administered standing IV acetaminophen every 6 h for a minimum of 48 h as the main form of post-operative analgesia. Pain severity was objectively scored using the Face, Legs, Activity, Cry, and Consolability (FLACC) scale. A before-and-after retrospective cohort analysis was performed and process control charts were used to examine trends in post-operative opiate use in our pre-intervention (January 2012 to January 2016), roll-out (January 2016 to December 2016), and post-intervention (December 2016 to December 2020) cohorts. RESULTS: A total of 131 infants were included: 56 in the pre-intervention, 17 in the roll-out, and 58 in the post-intervention group. Patient demographics were equivalent. The intervention was associated with a 36-fold reduction in post-operative morphine equivalents (median 0.36 mg/kg in the pre-intervention group versus 0.0 mg/kg in the post-intervention group, P < 0.0001). The median and maximum FLACC pain scores along with clinical safety profiles were statistically equivalent between the groups. The intervention was associated with a 2-d reduction in post-operative length of stay (P < 0.0001). CONCLUSIONS: Standing IV acetaminophen is associated with a reduction of post-operative opioid use in infants being treated on the acute care floor while maintaining equivalent FLACC pain scores. Similar opiate reduction strategies may be of value at other institutions.

BACKGROUND: In July 2003, an 80-h work week restriction for residencies was mandated. This was met with skepticism regarding its potential impact on operative training. We hypothesized no difference in outcomes for pediatric surgeons who trained under duty hour restrictions compared to historical complication rates. METHODS: Dual-institutional review of pediatric patients who underwent five of the most common operations (2013-2018) by first-year pediatric surgeons who trained under duty hour restrictions was performed. Tests of proportions were used to compare complication rates to published rates on data collected prior to 2003. RESULTS: Patient mean age was 10.1 years. No significant differences (p values > 0.05) were found in laparoscopic appendectomy rates of infection, bleeding or intra-abdominal abscess compared to previously published rates. Pyloromyotomy rates of infection or duodenal perforation were not different. No differences were detected in rates of infection, recurrence or testicular atrophy for inguinal hernia repair. Umbilical hernia rates of infection, bleeding, and recurrence were also not different. There was no difference in CVC rates of hemopneumothoraces; significantly more bleeding events were detected (1.2% vs. 0.1%; p value = 0.04). CONCLUSION: In this study, first-year complication rates of pediatric surgeons who trained under duty hour restrictions were not significantly different when compared to published rates.

PURPOSE: Pediatric surgeons at our institution are often asked by families about a theoretical increased risk of severe common upper respiratory infections in children status post lung resection. No data exist on this topic. We, therefore, aimed to examine the risk of severe respiratory infection in children after pulmonary resection. METHODS: A chart review was conducted on all pediatric patients who underwent pulmonary resection between August 1st, 2009 and January 31st, 2019. Collected data included patient characteristics, operation, complications and any admission for respiratory infection. RESULTS: Fifty-seven patients met inclusion criteria. Resections included lobectomy (45.6%), segmentectomy (14.0%), and wedge resection (40.4%). Twelve (21.1%) were immunocompromised and 6 (10.5%) had post-operative complications. Within 1 year of surgery, 2 (3.5%) patients were hospitalized for a viral upper respiratory illness (URI), 1 (1.8%) for bacterial pneumonia, and none due to influenza. CONCLUSION: In the general pediatric population, the risk of admission for respiratory illness is 3-21%. At this institution, overall risk of respiratory infection after lung resection appears comparable to baseline community risk. Our findings could aid counseling pediatric patients and their families regarding the 1-year risk of infection after lung resection.

BACKGROUND: The incidence of inguinal hernias in premature infants is approximately 30%. Due to concerns about a high risk of incarceration, early repair is commonly performed. We present a series of patients whose families opted to delay repair until after 55 weeks corrected gestational age (GA) and experienced safe clinical regression of their hernias. METHODS: Between June 2015 and July 2020, premature infants (< 37 weeks GA) diagnosed with inguinal hernias on physical examination were identified. Families of eligible infants were offered either immediate or delayed repair after 55 weeks corrected GA. Infants whose families elected to delay were followed until their hernia(s) clinically regressed, or until older than 55 weeks. RESULTS: Families of 68 infants consented to delay repair. 23 infants (33.8%) had hernias that clinically regressed at median follow up from diagnosis of 14.1 weeks. Univariate analysis demonstrated female sex as a significant predictor of hernia clinical regression (OR: 3.08; p = 0.046). Of the 45 infants who underwent repair, 84.4% safely progressed to 55 weeks corrected GA prior to. CONCLUSION: Delaying inguinal hernia repair in this series of premature infants until after 55 weeks corrected GA revealed that one third of hernias, especially in females, safely regressed upon follow-up examination.

BACKGROUND: Gastrostomy tube (GT) placement is a common pediatric surgical procedure typically indicated for oral aversion. This may develop in patients with congenital heart disease (CHD) who require an orthotopic heart transplant (OHT). The safety profile of GT placement in OHT patients who are immunosuppressed is unknown. Given the potential increased risk of wound site complications on a patient receiving immunosuppression, we sought to determine the safety profile of GT placement in pediatric patients with OHT. MATERIALS AND METHODS: We performed a retrospective case series of all pediatric OHT recipients who subsequently underwent GT placement from January 1, 2009, to August 1, 2018, at the University of Virginia Children's Hospital. Major GT complications of wound breakdown, wound infection, peristomal GT leakage, ileus, or persistent emesis, and minor GT complication including the presence of granulation tissue are reported. RESULTS: Six patients who had a pediatric OHT subsequently underwent GT placement over the study period. There were no major 30-day or 90-day GT complications. One patient had excessive granulation tissue at their GT site. There were no accounts of acute kidney injury, urinary tract infection, sepsis, or pneumonia. CONCLUSION: Gastrostomy tube (GT) placement appears to be safe in pediatric OHT patients who are on immunosuppressive medications and unable to feed orally. This is the first study documenting the safety profile of GTs in pediatric OHT patients and may aid clinicians to make decisions regarding this intervention.

The usual indications for extra corporeal membrane oxygenation (ECMO) are for respiratory or cardiac failure. Although continuous renal replacement therapy (CRRT) is frequently used when patients are on ECMO, the need for CRRT as the primary indication for ECMO is rare. A case of a neonate placed onto veno-venous ECMO for the use of CRRT to treat hyperammonemia from propionic acidemia is presented.

INTRODUCTION: Racial disparities in health outcomes continue to exist for children requiring surgery. Previous investigations suggest that clinical protocols may reduce racial disparities. A post-operative opioid reduction protocol was implemented in children undergoing abdominal surgery who were less than 1 years old at a tertiary level hospital. The purpose of this investigation was to determine if the clinical protocol was associated with a reduction in racial disparity in post-operative opioid prescribing patterns and associated clinical outcomes. METHODS: A post-operative opioid reduction protocol based on standing intravenous acetaminophen, educational sessions with nursing staff, and standardized post-operative sign-out between the surgical and NICU teams was implemented in children under 1 year old in 2016. A time series and before and after analysis was conducted using a historical pre-intervention cohort (Jan 2011-Dec 2015) and prospectively collected post-intervention cohort (Jan 2016-Jan 2021). Primary outcomes included post-operative opioid use and post-operative pain scores stratified by race. Secondary outcomes included associated clinical outcomes also stratified by race. RESULTS: A total of 249 children were included in the investigation, 117 in the pre-intervention group and 132 in the post intervention group. The majority of patients in both cohorts were either White or Black. The two cohorts were equally matched in terms of pre-operative clinical variables. In the pre-intervention cohort, the median post-operative morphine equivalents in White children was 2.1 mg/kg (IQR 0.2, 11.1) while in Black children it was 13.1 mg/kg (IQR 2.4, 65.3), p-value = 0.0352. In the post-intervention cohort, the median value for White children and Black children was statistically identical (0.05 mg/kg (IQR 0, 0.5) and 0.0 mg/kg (IQR 0, 0.3), respectively, p-value = 0.237). This pattern was also demonstrated in clinical variables including length of stay, intubation length and total parenteral nutrition use. In the pre-intervention cohort, the total length of stay for white children was 16 days while for black children it was 45 days (p = 0.007). In the postintervention cohort the length of stay for both White and Black children were identical at 8 days (p = 0.748). CONCLUSION: The use of a clinical opioid reduction protocol implemented at a tertiary medical center was associated with a reduction in racial disparity in opioid prescribing habits in children. Prior to the protocol, there was a racial disparity in clinical variables associated with prolonged opioid use including length of stay, TPN use, and intubation length. The clinical protocol reduced variability in opioid prescribing patterns in all racial groups which was associated with a reduction in variability in associated clinical variables. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: Data examining rates of postoperative complications among SARS-CoV-2 positive children are limited. The purpose of this study was to evaluate the impact of symptomatic and asymptomatic SARS-CoV-2 positive status on postoperative respiratory outcomes for children. METHODS: This retrospective cohort study included SARS-CoV-2 positive pediatric patients across 20 hospitals who underwent general anesthesia from March to October 2020. The primary outcome was frequency of postoperative respiratory complications, including: high-flow nasal cannula/non invasive ventilation, reintubation, pneumonia, Extracorporeal Membrane Oxygenation (ECMO), and 30-day respiratory-related readmissions or emergency department (ED) visits. Univariate analyses were used to evaluate associations between patient and procedure characteristics and stratified analyses by symptoms were performed examining incidence of complications. RESULTS: Of 266 SARS-CoV-2 positive patients, 163 (61.7%) were male, and the median age was 10 years (interquartile range 4-14). The majority of procedures were emergent or urgent (n = 214, 80.5%). The most common procedures were appendectomies (n = 78, 29.3%) and fracture repairs (n = 40,15.0%). 13 patients (4.9%) had preoperative symptoms including cough or dyspnea. 26 patients (9.8%) had postoperative respiratory complications, including 15 requiring high-flow oxygen, 8 with pneumonia, 4 requiring non invasive ventilation, 3 respiratory ED visits, and 2 respiratory readmissions. Respiratory complications were more common among symptomatic patients than asymptomatic patients (30.8% vs. 8.7%, p = 0.01). Higher ASA class and comorbidities were also associated with postoperative respiratory complications. CONCLUSIONS: Postoperative respiratory complications are less common in asymptomatic versus symptomatic SARS-COV-2 positive children. Relaxation of COVID-19-related restrictions for time-sensitive, non urgent procedures in selected asymptomatic patients may be reasonably considered. Additionally, further research is needed to evaluate the costs and benefits of routine testing for asymptomatic patients. LEVEL OF EVIDENCE: Iii, Respiratory complications.

BACKGROUND: Waste is endemic in the U.S. health care system. Operating rooms are a source of significant solid waste. Surgeons are integral to many decisions in the operating room. METHOD: Online survey of surgeons at 2 major academic centers in the United States assessing perspectives on intraoperative waste and willingness to work to actively reduce intraoperative waste. RESULTS: We received responses from 219 surgeons: 90% agreed or strongly agreed that waste of sterile surgical items is an issue, and 95% agreed or strongly agreed to a willingness to change the operating room workflow to reduce waste. Surgeons estimated 26% of single-use, sterile supplies opened for surgery were unused at the end of the case. The barriers to waste reduction cited most frequently were: (1) lack of awareness of waste, (2) lack of concern for waste, and (3) lack of time to address the waste. CONCLUSION: Surgeons understand there is significant waste in the operating room and are willing to change their workflow to reduce waste. Changes in operating room practices that reduce waste will be beneficial to health systems' finances and their efforts to improve population health through a reduction in consumption and pollution. Efforts should be directed toward reducing operating room waste with an initial focus on the elimination of unnecessary waste of sterile surgical supplies. Further work is needed to determine the precise sources of perioperative waste and what initiatives can be implemented to reduce this burden while maintaining high-value patient care.

BACKGROUND: A limited number of post-operative opioid reduction strategies have been implemented in the neonatal population. Given the potential neurodevelopment effects of prolonged opioid use, we created a quality improvement initiative to reduce opioids in our NICU and evaluated the intervention in our CDH population. METHODS: Our opioid reduction intervention was based on standing post-operative IV acetaminophen, standardizing post-surgical sign-out between the surgical, anesthesia and NICU teams and a series of education seminars with NICU providers on post-operative pain control management. A historical control was used to perform a retrospective cohort analysis of opioid prescribing patterns in addition to a utilizing process control charts to investigate time trends in prescribing patterns. RESULTS: Forty-five children with CDH underwent an operation were included in our investigation- 18 in our pre-intervention cohort, 6 in a roll-out cohort and 21 in our post-intervention cohort. Each cohort was clinically similar. The intervention reduced total post-operative opioid use (morphine equivalents) from 82.2 (mg/kg) to 2.9 (mg/kg) in our post-intervention group (p < 0.0001). Our maximum Neonatal Pain and Agitation Sedation Score over the first 48 post-operative hours were equivalent (p = 0.827). Safety profiles were statistically equivalent. The opioid reduction intervention reduced post-operative intubation length from 156 to 44 h (p = 0.021). CONCLUSION: A multi-tiered intervention can decrease opioid use in post-surgical neonates with complex surgical pathology including CDH. The intervention proposed in this investigation is safe and does not increase pain or sedation scores in neonates, while lessening post-operative intubation length. EVIDENCE LEVEL: Level II.

BACKGROUND: Medical errors were largely concealed prior to the landmark report "To Err Is Human". The purpose of this systematic scoping review was to determine the extent pediatric surgery defines and studies errors, and to explore themes among papers focused on errors in pediatric surgery. METHODS: The methodological framework used to conduct this scoping study has been outlined by Arksey and O'Malley. In January 2020, PubMed, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials were searched. Oxford Level of Evidence was assigned to each study; only studies rated Level 3 or higher were included. RESULTS: Of 3,064 initial studies, 12 were included in the final analysis: 4 cohort studies, and 8 outcome/audit studies. This data represented 5,442,000 aggregate patients and 8,893 errors. There were 6 different error definitions and 5 study methods. Common themes amongst the studies included a systems-focused approach, an increase in errors seen with increased complexity, and studies exploring the relationship between error and adverse events. CONCLUSIONS: This study revealed multiple error definitions, multiple error study methods, and common themes described in the pediatric surgical literature. Opportunities exist to improve the safety of surgical care of children by reducing errors. Original Scientific Research Type of Study: Systematic Scoping Review Level of Evidence Rating: 1.

OBJECTIVE: To report an atypical presentation of pH1N1-09 influenza infection in children as fulminant myocarditis and tamponade and the successful treatment with extracorporeal membrane oxygenation. DESIGN: Case report. SETTING: Pediatric cardiac intensive care unit in a quarternary care children's hospital. PATIENTS: Two girls, 5 and 7 yrs of age, infected with pH1N1-09 influenza virus who presented in cardiogenic shock with a pericardial effusion and echocardiographic evidence of tamponade from fulminant myocarditis. INTERVENTIONS: Both patients received a pericardiocentesis. One was managed with multiple, high-dose inotropic agents, whereas the other required institution of extracorporeal membrane oxygenation. MEASUREMENTS AND MAIN RESULTS: Acute respiratory distress syndrome is the major reported clinical manifestation of pH1N1-09 influenza virus infection in hospitalized pediatric patients. In this report we describe two children with confirmed pH1N1-09 influenza infection that required intensive care for fulminant myocarditis. Neither patient had the typical symptoms of influenza-like illness, respiratory compromise, or evidence of pulmonary involvement. One child required extracorporeal membrane oxygenation. Both children survived to hospital discharge. CONCLUSIONS: pH1N1-09 influenza infection can cause fulminant myocarditis in the healthy pediatric population. The clinical presentation may be nonspecific, and the lack of pulmonary symptoms may make diagnosis difficult. Extracorporeal membrane oxygenation support may offer an effective bridge to the recovery of heart function.

BACKGROUND AND OBJECTIVES: Opiate use in neonates can affect clinical outcomes after surgery and may alter future neurodevelopment. We implemented a multimodal opioid reduction strategy in our NICU for infants undergoing nonemergent gastrointestinal surgery. METHODS: After multiple stakeholder's meetings, our opioid reduction intervention included giving neonates postoperative standing intravenous acetaminophen every 6 hours for 48 hours, a standardized postsurgical sign-out with the NICU team in which pain control was directly addressed, and a series of postsurgical pain education seminars with NICU providers. To assess the impact of our quality improvement project, we used process control charts to investigate trends in postoperative opioid use in our preintervention (January 2012 to April 2016) and postintervention (May 2016 to September 2019) cohorts. RESULTS: A total of 77 infants were included in the study (40 in the preintervention cohort and 37 in the postintervention cohort). Patient characteristics were equivalent. The intervention significantly reduced the trend in postoperative morphine equivalents (median: 7.96 mg/kg in preintervention cohort versus 0.095 mg/kg in postintervention cohort; P < .0001). The Neonatal Pain, Agitation, and Sedation Scale pain scores and safety profiles were equivalent in both groups. The intervention was also associated with a 24-hour reduction in postoperative ventilation time (P < .048) and a 7-day reduction in the use of total parenteral nutrition (P < .017). CONCLUSIONS: Standing intravenous acetaminophen coupled with provider education can successfully reduce opioid use in postsurgical neonates. Given the concern for opioid exposure in neonatal neurodevelopment as well as clinical benefits of reduced opioids, similar strategies for opioid reduction may prove useful at other institutions.

Esophageal perforation is most commonly iatrogenic in origin with nasogastric tube insertion, stricture dilation, and endotracheal intubation, being the most frequent sources of the injury in infants and children. Clinical presentation depends on whether the cervical, thoracic, or abdominal esophagus is injured. Any patient complaining of chest pain after an upper endoscopy has esophageal perforation until proven otherwise. In infants and children, plain chest films and esophagography may assist in making the diagnosis. Hemodynamically stable patients with a contained perforation may be managed medically. Free perforation and hemodynamic lability mandates a more aggressive surgical approach for wide drainage of the mediastinum and pleural spaces. Exploration of the chest for attempted direct repair of the injury is now only rarely indicated. Mortality rates have been reported between 20 and 28% with delays in diagnosis and treatment appearing to be most strongly correlated with poor outcomes.

OBJECTIVE: Case series have demonstrated sutureless closures to be safe for the correction of gastroschisis. We hypothesize that sutureless closure is efficacious in patients requiring silo reduction without need for intubation. STUDY DESIGN: We conducted a retrospective case control study of infants who underwent gastroschisis repair at our institution (January 2011-August 2018). Patient characteristics and clinical outcomes were compared between sutureless closure and primary fascial repair groups. RESULTS: Seventeen patients in the sutureless group and 28 patients in the primary fascial repair group were included. Success of sutureless closure was 94%. Mechanical ventilation was reduced by 2.8 days in the sutureless group (P < 0.0001) and fewer patients required general anesthesia (29.4% vs. 100%, P < 0.0001). CONCLUSIONS: Sutureless closure is effective for the diverse presentations of gastroschisis. Given the concerns of effects of general anesthesia on the developing brain, sutureless closure should be strongly considered.

INTRODUCTION: The Malone appendicostomy is a continent channel used for antegrade enemas. It requires daily cannulation and is susceptible to stenosis. We use an indwelling low-profile balloon button tube inserted through the appendix into the cecum for antegrade enemas. We hypothesized that this method is effective at managing constipation or fecal incontinence and is associated with a low rate of stenosis. METHODS: Children who underwent laparoscopic appendicostomy balloon button placement at our institution from January 2011 to April 2017 were identified. The primary outcome was success in managing constipation or fecal continence as measured by the Malone continence scale. Postoperative complications were analyzed. RESULTS: Thirty-six children underwent the procedure, 35 of which met the inclusion criteria. Thirty-one patients (88.5%) underwent the operation for idiopathic constipation, 3 patients (8.6%) for anorectal malformation, and 1 patient (2.9%) for hypermobility. Rate of open conversion was 3%. A full response was obtained in 24 patients (68.6%), partial response in 9 patients (25.7%), and 2 patients failed (5.7%). One patient developed an internal hernia requiring laparotomy and later developed mucosal prolapse. One patient developed a stricture noted at button change. Seven patients (20%) underwent reversal of their appendicostomy tube: 5 due to return of normal bowel function and 2 due to discomfort with flushes. CONCLUSION: A laparoscopic appendicostomy with a balloon button tube is an effective means of addressing chronic constipation or fecal incontinence. The stenosis rate associated with tube appendicostomy may be lower than those reported for Malone antegrade continence enema procedures.

Although anti-angiogenic agents have shown promise as cancer therapeutics, their efficacy varies between tumor types and individual patients. Providing patient-specific metrics through rapid noninvasive imaging can help tailor drug treatment by optimizing dosages, timing of drug cycles, and duration of therapy-thereby reducing toxicity and cost and improving patient outcome. Diffuse optical tomography (DOT) is a noninvasive three-dimensional imaging modality that has been shown to capture physiologic changes in tumors through visualization of oxygenated, deoxygenated, and total hemoglobin concentrations, using non-ionizing radiation with near-infrared light. We employed a small animal model to ascertain if tumor response to bevacizumab (BV), an anti-angiogenic agent that targets vascular endothelial growth factor (VEGF), could be detected at early time points using DOT. We detected a significant decrease in total hemoglobin levels as soon as one day after BV treatment in responder xenograft tumors (SK-NEP-1), but not in SK-NEP-1 control tumors or in non-responder control or BV-treated NGP tumors. These results are confirmed by magnetic resonance imaging T2 relaxometry and lectin perfusion studies. Noninvasive DOT imaging may allow for earlier and more effective control of anti-angiogenic therapy.

Agents targeting vascular endothelial growth factor (VEGF) have been validated as cancer therapeutics, yet efficacy can differ widely between tumor types and individual patients. In addition, such agents are costly and can have significant toxicities. Rapid noninvasive determination of response could provide significant benefits. We tested if response to the anti-VEGF antibody bevacizumab (BV) could be detected using contrast-enhanced ultrasound imaging (CEUS). We used two xenograft model systems with previously well-characterized responses to VEGF inhibition, a responder (SK-NEP-1) and a non-responder (NGP), and examined perfusion-related parameters. CEUS demonstrated that BV treatment arrested the increase in blood volume in the SK-NEP-1 tumor group only. Molecular imaging of α(V)ß(3) with targeted microbubbles was a more sensitive prognostic indicator of BV efficacy. CEUS using RGD-labeled microbubbles showed a robust decrease in α(V)ß(3) vasculature following BV treatment in SK-NEP-1 tumors. Paralleling these findings, lectin perfusion assays detected a disproportionate pruning of smaller, branch vessels. Therefore, we conclude that the response to BV can be identified soon after initiation of treatment, often within 3 days, by use of CEUS molecular imaging techniques. The use of a noninvasive ultrasound approach may allow for earlier and more effective determination of efficacy of antiangiogenic therapy.
