Johnston WR, Hwang R, Mattei P. Impact of microscopic deposits of yolk sac tumor on recurrence of mature sacrococcygeal teratoma. J Surg Oncol 2024.

Abstract
INTRODUCTION Sacrococcygeal teratomas (SCT) with malignant histology frequently recur and are treated aggressively, but risk factors and surveillance protocols are less established for mature tumors. In particular, prior studies have not investigated whether microscopic deposits of yolk sac tumor (YST) in otherwise mature teratomas lead to higher recurrence rates. METHODS We reviewed patients with mature SCTs resected at our institution from 2011 to 2021 and analyzed tumor characteristics, treatment, and outcomes. RESULTS We identified 56 patients with mature SCT, of which 9 (16%) demonstrated microscopic YST. Following surgery, 7/56 (13%) patients developed local recurrence at a mean of 1.2 ± 0.7 years, while no patients developed metastases. Recurrence was more likely in patients with microscopic YST [5/9 (56%) vs. 2/47 (4%), p = 0.021] and positive margins [6/24 (35%) vs. 1/32 (3.1%), p = 0.030]. A solid tumor component tended to increase recurrence risk as well [6/29 (21%) vs. 1/27 (4%), p = 0.053]. Five patients demonstrated malignant recurrence and were all detected by a rising alpha-fetoprotein (AFP), while two patients demonstrated recurrence of mature teratoma and were detected on surveillance magnetic resonance imaging (MRI). CONCLUSIONS Microscopic foci of YST may increase recurrence risk for patients with mature SCT. Such patients might benefit from closer postoperative surveillance with serial AFP measurements and MRI.

Abstract
INTRODUCTION Surveillance following sacrococcygeal teratoma (SCT) resection varies. The purpose of this study was to describe the clinical characteristics and outcomes of patients undergoing SCT resection and examine current institutional practices to detect recurrence. METHODS A single-institution retrospective review of children who underwent resection of an SCT from January 1, 2010 to December 31, 2020 was performed. Data were summarized and surveillance strategies compared between histopathologic subtypes using nonparametric methods. RESULTS Thirty six patients (75.0% female) underwent SCT removal at a median age of 8 d. Histopathology revealed 27 mature teratomas (75.0%), eight immature teratomas (22.2%), and one malignant germ cell tumor (2.8%). Median postoperative follow-up was 3.17 y (interquartile range [IQR]: 2.31-4.38 y). Patients had a median of 2.32 clinic visits per year (IQR: 2.00-2.70), alpha-fetoprotein levels were obtained at a median of 2.01 times per year (IQR: 0-1.66), and surveillance imaging was performed at a median of 2.31 times per year (IQR: 0-2.84). Patients with immature teratomas had alpha-fetoprotein laboratories obtained more frequently than patients with mature teratomas (3.10 times/year versus 0.93 times/year, P = 0.001). There was no significant difference in the number of imaging studies obtained between groups. Two patients (5.6%) developed recurrence, which were identified on magnetic resonance imaging at 191 and 104 d postresection, respectively. CONCLUSIONS Postoperative surveillance practices varied widely. Recurrence was noted in a single malignant case in the first year following resection. Multi-institutional studies are needed to determine the optimal surveillance strategy to detect recurrence of SCT.

Abstract
Immature sacrococcygeal teratoma represents a histological form with rapid tumor growth, a risk of premature birth, an enhanced rate of complications, an increased risk of recurrence, and a higher mortality rate than the mature type. Thus, prenatal diagnosis of immature forms would significantly improve the prognosis of these cases. To this end, we performed an extensive literature review on the diagnosis, therapeutic management, and follow-up of immature teratomas. Regarding this medical conduct, we also presented our case. In conclusion, the early identification of immature sacrococcygeal teratomas with or without other associated structural abnormalities and their correct therapeutic approach are basic principles for a favorable evolution of these cases.

Abstract
AIM OF THE STUDY Outcome of fetuses, prenatally diagnosed with sacrococcygeal teratoma (SCT), is still poorly documented. This study assesses the incidence and prenatal predictors of outcome in all fetuses prenatally diagnosed with SCT. METHODS This is a retrospective study on all fetuses prenatally diagnosed with SCT from 1998 to 2018 in the Netherlands. Poor outcome was defined as terminations of pregnancy (TOP) because of expected unfavorable outcome, intrauterine fetal death, or early neonatal death. Potential risk factors for poor outcome were analyzed. MAIN RESULTS Eighty-four fetuses were included. Sixteen (19.0%) TOPs were excluded from statistical analysis. Eleven of the remaining 68 fetuses had poor outcome. Overall mortality was 32.1%, with a mortality excluding TOPs of 13.1%. Thirteen fetal interventions were performed in 11 (13.1%) fetuses. Potential risk factors for poor outcome were the presence of fetal hydrops (OR: 21.0, CI: 2.6-275.1, p = 0.012) and cardiomegaly (OR: 10.3, CI: 1.9-55.8, p = 0.011). CONCLUSIONS The overall mortality of fetuses prenatally diagnosed with SCTs including tTOP was 32.1%. This high mortality rate was mainly due to termination of pregnancy. Mortality excluding TOP was 13.1%. Potential risk factors for poor outcome were fetal hydrops and cardiomegaly.

Malignant recurrence after mature Sacrococcygeal teratoma: A meta-analysis and review of the literature. Crit Rev Oncol Hematol 2020; 156:103140.

Abstract
BACKGROUND AND AIMS Sacrococcygeal teratoma (SCT) is a rare extragonadal germ cell tumour mostly diagnosed during infancy and early childhood. Neonatal SCTs are mostly mature, but can also contain immature and/or malignant components. Recurrence of an SCT alters prognosis, especially when it is malignant, of which its mechanism is not yet fully understood. This study is a review and meta-analysis of the literature on malignant recurrences after an initially mature SCT. METHODS A literature search was performed to identify studies describing children with SCT and presenting specific information on histology of the initial tumour as well as the recurrence. Random effect models for mature recurrence and malignant recurrence after an initially mature SCT were employed to pool study-specific percentages in order to estimate an overall percentage and its associated 95 % confidence intervals (CI). Inverse variance method, which gives more weight to larger studies, was used to pool outcomes for the different studies. RESULTS A total of 22 articles, comprising 1516 patients with SCT, were included in the meta-analysis. The pooled proportions of mature and malignant recurrences after mature SCT were 3 % (95 % CI 1-4 %) and 5% (95 % CI 3-6 %), respectively. Fifty-seven (56 %) of a total of 102 recurrences after resection of an initially mature SCT were malignant, mostly yolk sac tumour (YST). Many recurrences occurred within 1-6 years, however some occurred as long as 20 years after initial diagnosis. CONCLUSIONS A substantial number of recurrences of mature SCT present as a malignant tumour. Overlooking malignant components on initial pathological evaluation and the progression of mature SCT cells to malignant cells may play a role. Treatment of mature SCTs with resection alone requires thorough follow-up of at least 6 years. Future research is needed to determine whether SCTs with malignant microfoci should be treated or followed-up differently from mature or immature SCTs. In addition, the value of serum biomarkers in follow-up after SCT needs to be further evaluated.

Abstract
BACKGROUND Sacrococcygeal teratoma (SCT) is the most common extragonadal germ cell tumor in neonates and infants. Although most cases of infantile SCT are benign tumors by nature, some develop into extremely large lesions, leading to massive bleeding, high-output heart failure, disseminated intravascular coagulation, and even fatal outcomes during the neonatal period. In addition, some patients may present with tumor recurrence, malignant transformation, long-term sequelae (including bladder and bowel dysfunction) and lower leg palsy during the long-term follow up. SCT, however, is very rare, and there are few opportunities to encounter this disease, therefore general physicians without expert credentials currently lack information relevant to clinical practice. For this reason, the research project committee has compiled guidelines concerning SCT. METHODS The purpose of these guidelines was to share information concerning the treatment and follow up of infantile SCT. The guidelines were developed using the methodologies in the Medical Information Network Distribution System. A comprehensive search of the English- and Japanese-language articles in PubMed and Ichu-Shi Web identified only case reports or case series, and the recommendations were developed through a process of informal consensus. RESULTS The clinical questions addressed the risk factors, the efficacy of cesarean section, the initial devascularization of tumor feeding vessels, interventional radiology, recommended clinical studies for follow up and possible long-term complications. CONCLUSIONS These are the first guidelines for SCT to be established in Japan, and they may have huge clinical value and significance in terms of developing therapeutic strategies and follow up, potentially contributing to the improvement of the prognosis and quality of life of SCT patients.

Abstract
OBJECTIVES In sacrococcygeal teratoma, the presence of high-output cardiac failure resulting from arteriovenous shunting through the large tumor has been associated with an adverse outcome. The objective of this study was to determine whether the tumor size and cardiac biomarkers in cord blood can predict neonatal survival in sacrococcygeal teratoma. METHODS The study population consisted of 25 neonates with sacrococcygeal teratoma. Tumor size was calculated by the ellipsoid formula using dimensions measured by antenatal ultrasound ([length × width × depth in cm] × 0.52= volume in cm3 ). To adjust the gestational age, the tumor volume index (tumor volume/biparietal diameter) was adopted in the analysis. Cardiac biomarkers for heart failure (N-terminal pro-B-type natriuretic peptide [NT-pro-BNP] and cardiac troponin T [cTnT]) were measured in cord blood taken at the time of delivery. RESULTS The rate of neonatal death was 24% (6 of 25). The cases that resulted in neonatal death had a higher tumor volume index and higher concentrations of NT-pro-BNP and cTnT than those with survival. A tumor volume index of greater than 60 cm3 /cm, elevated NT-pro-BNP (>2000 pg/mL), and elevated cTnT (>0.08 ng/mL) had sensitivity of 100% for prediction of neonatal death. CONCLUSIONS The tumor volume index and cord blood biomarkers for heart failure can be promising prognostic markers for neonatal survival in sacrococcygeal teratoma.

Abstract
OBJECTIVE To evaluate urinary tract and bowel function in children with sacrococcygeal teratoma, compare the findings with healthy children, and assess predictors of poor outcome. STUDY DESIGN This was a controlled cohort study of all patients operated for sacrococcygeal teratoma at a tertiary pediatric surgery center, 2000-2013. Urinary and bowel function were compared with healthy control patients matched for age and sex. Perioperative and histopathologic risk factors were analyzed. RESULTS In total, 17 patients with sacrococcygeal teratoma and 85 healthy control patients were included in the study. Patients with sacrococcygeal teratoma more often were reported to have uncontrolled voiding (12% vs 0%, P < .01), difficulty in bladder emptying (24% vs 0%, P < .001), and pyelonephritis (18% vs 1%, P < .05). Constipation was more common in patients with sacrococcygeal teratoma (47 % vs 14%, P < .05), but the overall bowel function score was equal in the 2 groups. Children with large tumors and immature histology were more likely to have a dysfunctional outcome (P < .05). CONCLUSIONS Uncontrolled voiding, difficulty in bladder emptying, pyelonephritis, and constipation were more common in patients with sacrococcygeal teratoma than in healthy children. Dysfunctional outcome was more prevalent in children with large and immature teratomas.

Abstract
BACKGROUND Sacrococcygeal teratoma (SCT) is a rare congenital tumor associated with high rates of perinatal mortality and morbidity. This study evaluated the incidence, prenatal detection rate, and early predictors of a complicated outcome following diagnosis of SCT. METHODS We retrospectively identified all fetuses and newborns diagnosed with SCT in southern Sweden from 2000 to 2013. Prenatal sonograms, charts, and pathology reports were reviewed and analyzed. Each case of SCT was defined as complicated or uncomplicated based on the postnatal outcome. All cases with a fatal outcome or that required cardiac resuscitation during birth or surgery were classified as complicated. RESULTS The overall incidence of SCT was 1:13,982 (19 children in a cohort of 265,658 live births). A prenatal diagnosis was made in 74% of cases, there were no stillbirths or intrauterine deaths, and the overall mortality rate was 11%. Four cases of SCT (21%) were classified as complicated, and these cases had a significantly larger tumor size at gestational week 20 (P=0.048), had a significantly higher tumor growth rate (P=0.003), and were more often associated with polyhydramnios (P=0.01), and mainly solid/mixed morphology (P=0.001). CONCLUSIONS The incidence of SCT in southern Sweden was higher than those reported in most previous studies; however, the associated mortality rate was relatively low. Fetuses with large tumors, rapidly growing tumors, and polyhydramnios were more likely to experience a complicated outcome during the postnatal period.

Abstract
Sacrococcygeal teratoma (SCT) is a rare tumor, present in approximately one in 40,000 live births. A small proportion of SCT have malignant potential, so prompt recognition and surgical resection are necessary. We report two cases of SCT initially misdiagnosed as hemangiomas because of their cutaneous appearance and in particular vascular stains overlying soft tissue mass. These two cases emphasize that SCT should be considered in the differential diagnosis of hemangiomas and in particular of congenital hemangiomas.

Abstract
Although Harvey Cushing was a neurosurgical pioneer, his work on the spine remains largely unknown. In fact, other than his own publications, Cushing's patients with pathological lesions of the spine who were treated while he was at the Johns Hopkins Hospital, including those with spinal cord tumors, have never been previously described. The authors report on 7 patients with spinal cord tumors that Cushing treated surgically between 1898 and 1911: 2 extradural, 3 intradural extramedullary, and 2 intramedullary tumors. The authors also describe 10 patients in whom Cushing performed an "exploratory laminectomy" expecting to find a tumor, but in whom no oncological pathological entity was found. Cushing's spine surgeries were limited by challenges in making the correct diagnosis, lack of surgical precedent, and difficulty in achieving adequate intraoperative hemostasis. Other than briefly mentioning 2 of the 4 adult patients in his landmark monograph on meningiomas, these cases-both those involving tumors and those in which he performed exploratory laminectomies--have never been published before. Moreover, these cases illustrate the evolution that Harvey Cushing underwent as a spine surgeon.

Abstract
Resection of large sacrococcygeal teratomas (SCT) in neonates can pose many anesthetic challenges. The pathophysiology of the SCT determines the varying management. We present a case report of a 34-week newborn with a massive Altman type 3 SCT. The surgery was delayed 2 days because of hyperkalemia; however, as a result of continued tumor lysis the patient's condition had worsened with little improvement of the potassium level. During the surgery, the patient had issues of bleeding needing massive transfusion. Ventilation was also difficult at times because of the massive tumor resting on the chest, resulting in respiratory acidosis. We also had difficulty in maintaining the temperature. This patient did well after the surgery and was discharged home. We address here the anesthetic issues involved in the perioperative care management of a premature infant with a massive SCT.

Abstract
Congenital fetal tumours are rare, but current imaging modalities including US and MRI facilitate antenatal diagnosis and investigation, allowing a presumptive diagnosis and management strategy. Although the prevalence of fetal tumours is difficult to ascertain, an incidence of 7.2 per 100,000 live births has previously been reported, with the incidence of neonatal malignancy estimated at 36.5 per million births. Teratomas and neuroblastomas are the most common solid tumours described. Tumours may be very large or associated with severe hydrops leading to significant dystocia with the potential for difficult vaginal or caesarean delivery. Once the diagnosis of a fetal tumour is made, optimal management incorporates a multidisciplinary approach including obstetrician, neonatologist, paediatric surgeon and paediatric oncologist so that counselling is appropriate and a clear management plan is in place for parents.

Abstract
Fetal sacrococcygeal teratoma (SCT) is rarely associated with spinal invasion. The prognostic significance of spinal invasion is unknown. In the past, invasion has been discovered by postnatal imaging or in the operating room. As screening ultrasounds have become more prevalent in the United States, more SCTs have been discovered and characterized prenatally. This screening has allowed for better birth planning and neonatal therapy. We report a case of SCT invading the spinal canal seen on prenatal ultrasound. To our knowledge, this is the first documented case of prenatally diagnosed SCT intraspinal invasion.

Abstract
PURPOSE The objective of this study is to describe a prognostic classification for prenatally diagnosed sacrococcygeal teratoma (SCT). METHODS Charts from 44 fetuses were reviewed. Three groups were defined as follows: group A--tumor diameter less than 10 cm, absent or mild vascularity and slow growth; group B--diameter 10 cm or greater, pronounced vascularity or high-output cardiac failure and fast growth; group C--diameter 10 cm or greater, predominantly cystic lesion with absent or mild vascularity and slow growth. RESULTS Size at diagnosis, growth rate, and vascularity were higher in group B. Gestational age at delivery was lower in group B. Eleven of 21 died in the perinatal period in group B and none in groups A and C. In group C, drainage or shunting of the SCT has been performed in 6 of 10 cases. CONCLUSIONS Group A is associated to good maternal and perinatal outcome, as well as group C, although shunting or drainage of the SCT could be necessary. Large fast-growing SCT with rich vascularity is associated with a higher perinatal mortality and morbidity than smaller lesions with mild vascularity.

Abstract
Sacrococcygeal teratomas are the most common tumors found in newborns and have a favorable outcome when diagnosed late in gestation. Solid, highly vascularized tumors diagnosed early in gestation have a higher incidence of hydrops fetalis and fetal demise. The following is a case report of a monochorionic twin gestation complicated by a solid highly vascular sacrococcygeal teratoma and the development of hydrops in the affected twin. In this case, serial ultrasound evaluations and timing of delivery optimized the outcome of the unaffected twin.

Abstract
PURPOSE The aim of this study was to explore effects of (1) histological involvement of resection margins with microscopic residue, (2) incomplete removal of coccyx, and (3) tumor spillage on recurrence and on survival in children operated upon for sacrococcygeal teratoma (SCT). METHODS Retrospective review of 70 patients treated between 1960 and 2003. RESULTS Fifty-four girls and 16 boys presented with SCT diagnosed prenatally (12), at birth (37), or later (21). Thirty-six percent of tumors were Altman type I, 27% type II, 18% type III, and 18% type IV. Histologically, mature teratoma was observed in 48 patients, immature teratoma in 11, yolk sac tumor (YST) in 9, embryonal carcinoma in one, and mixed tumor in one. Eighty-four percent of patients solely underwent surgical extirpation. Six (8.5%) patients died. However, mortality for the group of 42 patients treated during the past 15 years was as low as 2.5%. Tumor recurrence was observed in 5 patients, 2 of whom died. Of 3 patients with initially mature teratoma, 1 showed local immature recurrence and 2 malignant recurrences. One of the latter died. Of 2 patients with initially immature teratoma grade I, one relapsed with a benign lesion and one with YST leading to death. Possible eliciting factors had been demonstrated in 3 patients. Histological analysis of resection margins showed tumoral involvement in 11 patients (and also in one patient after resection of a recurrent tumor). Only one of those with YST focus in the resection margin showed recurrence. Intraoperative tumor spillage presented in 2 patients, who both died of metastatic disease. Spillage of tumoral cyst fluid occurred in 6, none developed recurrence. One of 5 patients whose coccyx had not been removed died of metastatic disease. One with immature teratoma developed a benign recurrent tumor. The other 3 showed no recurrence. CONCLUSIONS Microscopic involvement of the resection margins of mature or immature SCT is rarely associated with recurrence, provided there are no YST foci in the resection margins. A conservative attitude then appears to be justified. Spillage of cyst fluid was never associated with recurrence, unlike spillage of tumor and absence of removal of coccyx.

Abstract
BACKGROUND/PURPOSE Germ cell tumors are relatively common in the fetus and neonate and are the leading neoplasms in some perinatal reviews. The purpose of this study is to focus on the fetus and neonate in an attempt to determine the various ways germ cell tumors differ clinically and morphologically from those occurring in the older child and adult and to show that certain types of tumors have a better prognosis than others. METHODS The author conducted a retrospective review of perinatal teratomas and other germ cell tumors reported in the literature and of patients treated and followed up at Children's Hospital San Diego and Children's Hospital Los Angeles. Only fetuses and infants less than 2 months of age with adequate clinical and pathologic data were accepted for review. RESULTS Five hundred thirty-four fetuses and neonates presented with teratomas diagnosed prenatally (n = 226) and at birth (n = 309). The most common initial finding was a mass, noted either by antenatal sonography or by physical examination during the neonatal period, with signs and symptoms referable to the site of origin. Overall polyhydramnios was next followed by respiratory distress and stillbirth. The number of mature and immature teratomas was approximately the same. The incidence of teratoma with yolk sac tumor either at presentation or at recurrence was 5.8%, and the survival rate was 39%. Sacrococcygeal teratomas had the highest incidence of yolk sac tumor at 10%. Recurrent disease in the form of either teratoma or yolk sac tumor developed in 5% of patients. All individuals with teratomas who survived received surgical resection. CONCLUSIONS Some germ cell tumors of the fetus and neonate have a better prognosis than others. Neonates with gastric teratomas have the best survival rates, and those with intracranial germ cell tumors the worst. Fetuses with teratomas detected antenatally have 3 times the mortality rate compared with postnatally diagnosed neonates. Although perinatal teratomas have a relatively low recurrence rate of 5%, close follow-up with imaging studies and serum alpha-fetoprotein determinations is is strongly recommended. Surgical resection alone may be adequate therapy for teratomas with nonmetastatic, microscopic foci of yolk sac tumor. In the nonteratoma group, patients with pure yolk sac tumor and gonadoblastoma have a much better outcome than those with choriocarcinoma, which has a very low survival of rate of 12%. Currently, the use of platinum-based combination chemotherapy has significantly improved the survival rate of infants with advanced malignant germ cell tumor disease.

Abstract
BACKGROUND Long-term follow-up of sacrococcygeal teratoma (SCT) is well established; however, little is known about the effects of extensive surgery in the pelvic and perineal region, which involves disruption of muscles providing maximal support in normal walking. METHODS Thirteen patients operated on at birth for SCT with extensive muscle dissection underwent gait studies with a Vicon 3-D motion analysis system with 6 cameras. Results were compared with 15 age-matched controls. Statistical analysis was performed with Mann-Whitney test; correlations were sought with Spearman's correlation coefficient. RESULTS All subjects were independent ambulators, and no statistically significant differences were seen in walking velocity and stride length. However, in all patients, toe-off occurred earlier (at 58% +/- 1.82% of stride length) than controls (at 65.5% +/- 0.52%; P <.05). On kinetics, all patients exhibited, on both limbs, a significant reduction of hip extensory moment (-0.11 +/- 0.11 left; -0.16 +/- 0.15 right v 1.19 +/- 0.08 Newtonmeter/kg; P <.05) and of ankle dorsi/plantar moment (-0.07 +/- 0.09 right; -0.08 +/- 0.16 v -0.15 +/- 0.05 Nm/kg, p < 0.05). Knee power was also significantly reduced (0.44 +/- 0.55 right, 0.63 +/- 0.45 left v 0.04 +/- 0.05 W/kg), whereas ankle power was increased (3 +/- 1.5 right; 2.8 +/- 0.9 left v 1.97 +/- 0.2 W/kg; P <.05). No statistically significant correlation was found between tumor size and either muscle power generation or flexory/extensory moments. CONCLUSIONS Patients operated on for SCT exhibit nearly normal gait patterns. However, this normal pattern is accompanied by abnormal kinetics of some ambulatory muscles, and the extent of these abnormalities appears to be independent of tumor size. A careful follow-up is warranted to verify if such modifications are stable or progress over the years, thereby impairing ambulatory potential or leading to early arthrosis.

Abstract
PURPOSE To understand the natural history and define indications for fetal intervention in sacrococcygeal teratoma (SCT), the authors reviewed all cases of fetal SCT presenting for evaluation. METHODS Prenatal diagnostic studies including ultrasound scan, magnetic resonance imaging (MRI), echocardiography and pre- and postnatal outcomes were reviewed in 30 cases of SCT that presented between September 1995 and January 2003. RESULTS The mean gestational age (GA) at presentation was 23.9 weeks (range, 19 to 38.5) with 3 sets of twins (10%). Overall outcomes included 4 terminations, 5 fetal demises, 7 neonatal deaths, and 14 survivors. Significant obstetric complications occurred in 81% of the 26 continuing pregnancies: polyhydramnios (n = 7), oligohydramnios (n = 4), preterm labor (n = 13), preeclampsia (n = 4), gestational diabetes (n = 1), HELLP syndrome (n = 1), and hyperemesis (n = 1). Fetal intervention included cyst aspiration (n = 6), amnioreduction (n = 3), amnioinfusion (n = 1), and open fetal surgical resection (n = 4). Indications for cyst aspiration and amnioreduction were maternal discomfort, preterm labor, and prevention of tumor rupture at delivery. Although 15 SCTs were solid causing risk for cardiac failure, only 4 fetuses met criteria for fetal debulking based on ultrasonographic and echocardiographic evidence of impending high output failure and favorable anatomy at 21, 23.6, 25, and 26 weeks' gestation. Intraoperative events included maternal blood transfusion (n = 1), fetal blood transfusion (n = 2), chorioamniotic membrane separation (n = 2), and fetal arrest requiring successful cardiopulmonary resuscitation (CPR) (n = 1). In the fetal resection group, 3 of 4 survived with mean GA at delivery of 29 weeks (range, 27.6 to 31.7 weeks), mean birth weight of 1.3 kg, hospital stay ranging from 16 to 34 weeks, and follow-up ranging from 20 months to 6 years. Postnatal complications in the fetal surgery group included neonatal death (n = 1, secondary to premature closure of ductus arteriosus with cardiac failure), embolic event (n = 1, resulting in unilateral renal agenesis, jejunal atresia), chronic lung disease (n = 1), and tumor recurrence (n = 1). CONCLUSIONS For fetal SCT, the rapidity at which cardiac compromise can develop and the high incidence of obstetric complications warrant close prenatal surveillance. Amnioreduction, cyst aspiration, and surgical debulking are potentially life-saving interventions.
