Failure of MIBG scan to detect metastases in SDHB‐mutated pediatric metastatic pheochromocytoma

¹²³I‐meta‐iodo benzyl guanidine (MIBG) scans are considered the gold standard imaging in neuroblastoma; however, flouro deoxy glucose positron emission tomography (FDG‐PET) scans have increased sensitivity in adults with pheochromocytoma/paraganglioma. We describe a pediatric patient initially considered to have localized neuroblastoma based on anatomical imaging and ¹²³I‐MIBG scan, but subsequent investigations revealed germline succinate dehydrogenase complex iron sulfur subunit B (SDHB) mutation–associated pheochromocytoma with multiple FDG‐avid skeletal metastases. We then compared ¹²³I‐MIBG and FDG‐PET scans in children with metastatic pheochromocytoma/paraganglioma. FDG‐PET was superior to ¹²³I‐MIBG scan for the detection of skeletal metastases (median number of skeletal lesions detected 10 [range 1–30] vs. 2 [range 1–26], respectively; P = 0.005 by t‐test). FDG‐PET should be considered the functional scan of choice in children with pheochromocytoma/paraganglioma.     

Whole-body MRI of paediatric malignant tumours: comparison with conventional oncological imaging methods

Purpose: To evaluate the usefulness of whole-body (WB) MRI for detecting metastases from paediatric malignant tumours in comparison with conventional oncological imaging methods. Materials and methods: Using a 1.5-T system, a coronal short tau inversion recovery (STIR) sequence was obtained in all patients. In addition, sagittal fat-suppressed T2-weighted, sagittal STIR, or coronal fat-suppressed pre-contrast and post-contrast T1-weighted sequences were performed. Patients who underwent WB MRI and conventional oncological imaging within 15 days were enrolled in the study. In total, 58 bone scintigraphies, 26 iodine-123 (¹²³I) meta-iodo-benzylguanidine (MIBG) scintigraphies, and 48 CT scans were available for comparison in 36 patients (median age 3.5 years; 21 boys, 15 girls) who underwent 82 WB MRI examinations. Skeletal and extraskeletal metastases were evaluated for a variety of tumour types. Results: Concordance rate of WB MRI between two readers was 74%. In detecting metastases, WB MRI had higher sensitivity (99%) and PPV (94%) than bone scintigraphy (26 and 76%, respectively). In detecting skeletal metastases, WB MRI revealed higher sensitivity (100%) than ¹²³I-MIBG scintigraphy (25%) and CT (10%). In contrast, WB MRI showed lower PPV in detecting skeletal and extraskeletal metastases (8 and 57%, respectively) than ¹²³I-MIBG scintigraphy (100%), and lower sensitivity (60%) in detecting extraskeletal metastases than CT (100%). In 2 of 11 untreated patients, tumour staging was upgraded from stage 3 to 4 according to WB MRI findings. In 3 patients, WB MRI revealed early treatment responses (<1 year) of skeletal metastases. Conclusions: WB MRI can substitute for bone scintigraphy in detecting skeletal metastases of paediatric malignant tumours, and it is useful in evaluating initial tumour staging and early treatment responses. However, it still has only a complementary role in detecting extraskeletal metastases.     

Comparison of intracranial computed tomographic (CT) findings in pediatric abusive and accidental head trauma

Background. Child abuse specialists rely heavily on diagnostic neuroimaging. Objectives. Study objectives were: (1) to compare the frequencies of six specific intracranial CT abnormalities in accidental and non-accidental pediatric head trauma, and (2) to assess interobserver agreement regarding these CT findings. Materials and methods. Three pediatric radiologists blindly and independently reviewed cranial CT scans of pediatric patients who sustained closed head trauma between 1991 and 1994. All patients were less than 4 years of age. Study cases included thirty-nine (50 %) with non-accidental head trauma and thirty-nine (50 %) with accidental head trauma. Each scan was evaluated for the presence or absence of the following six intracranial findings: (1) interhemispheric falx hemorrhage, (2) subdural hemorrhage, (3) large (non-acute) extra-axial fluid, (4) basal ganglia edema, (5) posterior fossa hemorrhage, and (6) frontal-parietal shearing tear(s). Interobserver agreement was calculated as the percentage of total cases in which all reviewers agreed a specific CT finding was present or absent. Diagnosis required independent agreement by all three pediatric radiologists. The frequencies of these six intracranial CT abnormalities were compared between the two study groups by Chi-square analysis and Fisher's exact test. Results. Interobserver agreement between radiologists was greater than 80 % for all lesions evaluated, with the exception of frontal-parietal shearing tear(s). Interhemispheric falx hemorrhage, subdural hemorrhage, large (non-acute) extra-axial fluid, and basal ganglia edema were discovered significantly more frequently in non-accidental trauma (P≤ .05). Conclusion. Although not specific for child abuse, discovery of these intracranial CT abnormalities in young patients should prompt careful evaluation of family and injury circumstances for indicators of non-accidental trauma.

Chest radiographic features of thoracic metastatic disease in adolescents with colon cancer

This study describes chest radiographic features of thoracic metastatic disease (TMD) in patients referred for colon cancer to a pediatric oncology hospital. The study group was comprised of 9 patients (7 males, 2 females, age 13–19 years) with serial chest radiographs demonstrating TMD from colon cancer. All patients had a chest radiograph performed within the 2 months prior to death. The median interval from diagnosis of colon cancer to appearance of radiographic TMD was 3 months. Four of nine patients had TMD at presentation, eight of nine patients within 2 years of diagnosis. All abnormalities progressed on serial radiographs. The median interval from appearance of radiographic abnormalities to death was 2 months. Radiographic findings included pleural effusions (n=6), lymphadenopathy (n=5), lymphangitic carcinomatosis (n=4), solitary pulmonary nodule (n=2), and lobar atelectasis (n=1). Five patients with pleural effusions initially had right-sided effusions. Radiographic TMD in adolescents with colon cancer usually occurs within 2 years of diagnosis. Once TMD manifests, the prognosis is dismal. Findings include pleural effusions, lymphadenopathy, lymphangitic carcinomatosis, solitary pulmonary nodules, and lobar atelectasis. We suggest that metastatic colon carcinoma should be included in the differential diagnosis for lymphangitic spread of tumor in adolescents.Supported in part by National Cancer Institute Cancer Center Support (Core) grant P30CA21765, CA 23099, and by the American Lebanese Syrian Associated Charities (ALSAC)     

Coincidence FDG-PET in the evaluation of Langerhans' cell histiocytosis: preliminary findings

Background Bone involvement in Langerhans' cell histiocytosis (LCH) is common. Both bone scintigraphy and plain films are used to identify osseous lesions, but lack specificity for disease activity and response to therapy. FDG-PET is a sensitive technique for identifying bone lesions when histiocytes are present.Objective To describe the potential of coincidence FDG-PET (cFDG-PET) for identification of active bone lesions in LCH and to determine whether it can provide more specific information regarding lesional response to therapy than bone scintigraphy or radiography.Materials and methods The clinical data and imaging findings of three patients with osseous lesions of LCH were retrospectively reviewed.Results cFDG-PET identified all active LCH osseous lesions in these patients, differentiated active from healed lesions, and demonstrated normalization of uptake in a treated lesion earlier than bone scintigraphy and radiography.Conclusion cFDG-PET appears to have greater specificity than bone scintigraphy and radiography for the identification of active osseous lesions in LCH. It also may predict response to treatment earlier than conventional techniques. Its use in the evaluation of LCH warrants further study.Presented at the 2002 meeting of the Society for Pediatric Radiology, Philadelphia, Pennsylvania     

Comparison between x-ray and bone scan detection of bone metastases in patients with rhabdomyosarcoma

A comparison of radiographic and 99mTechnetium methyldiphosphonate scintigraphic evaluations for extent of skeletal disease was made retrospectively in 17 pediatric patients with Group III and IV rhabdomyosarcoma. Thirteen children had evidence of skeletal metastases. Of these, four exhibited multiple sites of blastic as well as lytic skeletal involvement on x-rays that were not detected by bone scans: two at the time of initial diagnosis, and two at relapse in children with prior radiotherapy to involved bones. In three additional patients a greater extent of bony disease was evident on x-rays than on bone scan. Neither the pathology of the tumor, lytic versus blastic quality of the bone lesion, nor lesion size per se was found to correlate with the failure to detect them on the bone scan. Although bone scans have greater sensitivity than x-rays for the detection of metastatic bone involvement in several adult and pediatric neoplasms, in the case of rhabdomyosarcoma, the radiographic exam appears to be a more sensitive indicator in some patients and should be considered an essential study in the evaluation of skeletal involvement by this tumor.     

Hypertension in children. Increased efficacy of technetium Tc 99m succimer in screening for renal disease

Renal scintigraphy with technetium Tc 99m succimer (DMSA) and technetium Tc 99m pentetate (DTPA) was used to study 80 hypertensive pediatric and adolescent patients. Renal abnormalities such as asymmetry of function, size, or shape were identified in 13 patients. Both excretory urography and technetium Tc 99m pentetate studies were successful in detecting 54% of the abnormalities in patients studied; technetium Tc 99m succimer identified 92%. The accuracy of the latter was 96%, with a specificity of 97%. The ability of technetium Tc 99m succimer renal scintigraphy to identify accurately the presence or absence of renal abnormalities warrants its inclusion in the initial examination of pediatric and adolescent patients with hypertension.     

Role of magnetic resonance imaging and scintigraphy in the diagnosis and follow-up of osteomyelitis in cat-scratch disease

Cat-scratch disease (CSD) is a self-limiting infectious disease characterised with lymphadenopathy in a patient with a history of cat contact. Cases of bone involvement in patients with CSD are rare. We reported a case of 11-year-old boy with prolonged intermittent fever, inguinal lymphadenopathy and osteomyelitis. He had a history of exposure to kittens. The physical examination revealed a febrile boy without an apparent site of infection except an enlarged inguinal lymph node. Its histopathology demonstrated granulomatous lesion with no presence of acid-fast bacilli. Serum titers for Bartonella henselae were positive. Multiple bone lesions were detected by skeletal scintigraphy. Magnetic resonance imaging (MRI) confirmed and characterised osteolytic masses. The oral combination of azithromycin and rifampicin were given for 6 weeks with a good clinical response. At follow-up, the boy was without symptoms or signs of the disease. Successive MRI controls showed gradual regression of the bone lesions together with significant decrease of acute-phase reactants. In conclusion, CSD should be considered in the differential diagnosis of osteomyelitis. MRI is more reliable for the characterisation, evaluation of soft-tissue extension and follow-up of the bone lesions than scintigraphy. However, the later method permits an overview of the multiple osseous lesions. Therefore, standard MRI equipment may not exclude bone scintigraphy. Both methods are required until whole-body MRI units become routine.     

Cardiac troponin I in pediatrics: Normal values and potential use in the assessment of cardiac injury

Objective: To establish normal values and determine the impact of congenital or acquired heart disease on serum cardiac troponin I (cTnI).Methods: Concentrations of cTnI were measured in two groups of children. Group A represented ambulatory pediatric patients with no apparent cardiac disease (n = 120) and patients in stable condition with known congenital or acquired cardiac abnormalities (n = 96); group B was composed of patients admitted to intensive care units with normal echocardiograms (n = 16), with abnormal echocardiograms (n = 36), and those with blunt chest trauma who were thought to have cardiac contusions (n = 7).Results: The cTnI concentrations were generally less than 2.0 ng/ml in group A and frequently below the level of detection for the assay (1.5 ng/ml). There was no statistical difference between the two outpatient subgroups ( p = 0.66). Nine intensive care patients had cTnI values greater than 2.0 ng/ml. Six of these patients, all with abnormal echocardiograms, had values less than 7.7 ng/ml. All improved and had subsequent normal cTnI concentrations. None of the three remaining patients (two with systemic illness [trauma and sepsis] and one with severe pulmonary hypertension), all with values greater than 8.0 ng/ml, survived. Three of the four patients with high likelihood of cardiac contusion had cTnI concentrations greater than 2.0 ng/ml (including one patient who died).Conclusions: Cardiac troponin-I values are generally not elevated in children with stable cardiac disease or general pediatric conditions. In the context of severe acute illness, significant elevation of cTnI may be an indicator of poor outcome. Elevation of cTnI may also have diagnostic value in cases when cardiac contusion is suspected. (J Pediatr 1997;130:872-7)     

Diagnosing cranial fasciitis based on distinguishing radiological features

Primary skull lesions, albeit rare in the pediatric population, have been well described and classified. These lesions are usually benign and commonly present as a painless mass. The most common lesions are epidermoid, dermoid, and Langerhans cell histiocytosis. Cranial fasciitis, encountered less frequently, is usually not considered in this differential diagnosis. Given such few cases reported, it is commonly misdiagnosed preoperatively. The authors retrospectively reviewed data obtained in 4 patients with cranial fasciitis in whom the diagnosis was based on histopathological findings. In 2 patients the onset of the lesion was spontaneous. One patient had a lesion 4 months following a vacuum extraction and subsequent cephalohematoma formation. One patient developed a lesion following a previous craniectomy. Presentation, imaging studies, and histopathological findings were all reviewed and analyzed. All patients presented with a firm nontender mass. Radiological features included a lytic bone lesion with a mildly sclerotic margin, T1 isodensity, T2 heterogeneous hyperdensity, and heterogeneous enhancement. The enhancing portion was not bright on T2-weighted MR images, likely representing the fibrous component; the nonenhancing portion was bright on T2-weighted images, likely representing the myxoid matrix. Histopathological examination revealed proliferating fibroblasts in a myxoid matrix. Cranial fasciitis is a benign, painless but rapidly growing lesion of the skull mainly limited to the pediatric population. It is histologically similar to nodular fasciitis, a fibroblastic proliferation of varying size. These lesions are often related to trauma but can also be insidious or can develop at a prior craniectomy site. The appropriate clinical picture and distinguishing radiographic features may help to differentiate cranial fasciitis from other lesions of the skull allowing for earlier intervention.     

Needle localization of small pediatric tumors for surgical biopsy

Background. Small pediatric tumors may be difficult to biopsy or resect. Objective. To examine the benefits of needle localization of a variety of small pediatric tumors before surgical biopsy or excision. Materials and methods. Seven patients aged 1–19 years underwent 12 procedures for needle localization of suspected tumor. Two patients had undergone previous biopsies without needle localization with negative results. Computed tomography (four patients) or ultrasonography (three patients) guided needle placement. Each patient had suspected tumor(s) in 1–3 anatomical sites, including thigh (7), lung (2), parasacral region (2), and iliac bone (1). Results. All 12 lesions (9 less than 1 cm³ in volume) were successfully localized for excision or biopsy. Three small (<1 cm³) soft-tissue lesions (two ganglioneuroblastomas and one ganglioneuroma) were excised from one patient, a 0.65-cm³ residual soft-tissue sarcoma from another; and recurrent bilateral teratomas from a third. Two peripheral primitive neuroectodermal tumors were excised with positive margins from a fourth patient. Two lesions contained only fibrosis, as determined by histopathology. Two other patients underwent thoracoscopic removal of lung metastases that were less than 0.1 cm³. Conclusion. Needle localization allows effective and less invasive excision or biopsy of a variety of small pediatric soft-tissue lesions. Received: 5 August 1999 Accepted: 7 December 1999     

Meta-Iodobenzylguanidine Scintigraphy in Neuroblastoma–a Comparison with Conventional X-Ray and Ultrasound

To evaluate the accuracy of meta-iodobenzylguanidine (MIBG) imaging in comparison with bone X-ray and ultrasound, 15 patients with histologically verified neuroblastoma were investigated using¹²³- or ¹³¹MIBG scintigraphy. ¹²³MIBG and ¹³¹MIBG are used as the abbreviations for 123-iodine-labeled-MIBG and 131-wdine-labeled-MIBG, respectively. Either 7.4 MBq ¹³¹MIBG (n = 4) or 111-185 MBq ^{123 >}MIBG (n = 11) was applied, and scans were performed 24 and 48 h PI. Anatomical orientation was provided in selected cases by single-photon emission CT or scintigraphy of other organs. X-ray procedures or ultrasound depicted 27 neuroblastoma manifestations (primary tumors and metastatic deposits); 24 of these (89 %) were identified by MIBG scintigraphy. Of 42 primary neuroblastomas and metastatic deposits, 27 (64%) were detected by corresponding bone X-ray or ultrasound. The 15 neuroblastoma lesions depicted solely by MIBG scans were mainly (80%) situated in the skeletal system. Because of the pronounced physiological MIBG uptake by liver tissue, detection of intrahepatic or perihepatic tumor involvement is difficult. MIBG scintigraphy is a safe and noninvasive means of locating a wide range of neuroblastoma lesions. Its main diagnostic advantage in comparison with bone X-ray lies in the detection of bone marrow infiltration.     

MRI of extracranial masses in children: the usefulness of gadolinium-chelate enhancement

Objective. This study evaluated the usefulness of gadolinium (Gd) chelates in magnetic resonance imaging (MRI) of extracranial pediatric mass lesions. Materials and methods. Seventy-five MRI studies were obtained on 60 children (mean age 5.06 years) with pathologically proven mass lesions. Post-contrast T1-weighted (T1W) images were compared with pre-contrast T1-weighted, T2-weighted (T2W) and both T1W and T2W images. They were evaluated for their ability to demonstrate lesion margins and extent, to add additional information, and to increase confidence in or change a diagnosis. In all patients post-contrast images were also evaluated for degree and pattern of enhancement. Results. Malignant lesions enhanced much more intensely than benign lesions (P < 0.0005). Lack of enhancement was seen only in benign lesions. A heterogeneous pattern of enhancement was more frequently seen in malignancy (P < 0.05). Additional information was provided on Gd-enhanced T1W images in 36 % of cases compared to unenhanced T1 and T2W images. Diagnostic confidence was improved in 29 %. The Gd-enhanced images changed the diagnosis correctly in 5 % and incorrectly in 1 %. Conclusion. Post-contrast images clarified specific issues, better defined lesion extent and margins in a majority of cases, and gave additional useful information in selected cases.

Sonography of pediatric male breast masses: gynecomastia and beyond

Background: Palpable breast masses are rare in the pediatric male population. Prior reports have described the ultrasound findings of the normal pediatric breast, masses seen primarily in female pediatric patients, and masses seen in adult males. Objective: To describe and illustrate the sonographic findings in gynecomastia and other causes of breast masses in a group of pediatric males. Materials and methods: We reviewed the ultrasound database of a large tertiary-care childrens hospital for male pediatric patients presenting with breast masses from 1994 to 2000. The findings were correlated with additional imaging and pathology results. Results: Twenty-five pediatric patients ranging in age from 1 month to 18 years were referred for breast ultrasound. Eighteen patients (72%) had gynecomastia. Two patients each (8%) had galactocele(s) or had postoperative hematoma. One patient had ductal ectasia, which resolved. One patient had periductal hemangioma. One patient with neurofibromatosis and a solid mass was lost to follow-up. Conclusion: Palpable breast masses are rare in the male pediatric patient and sonography is the primary imaging modality. The overwhelming majority of these cases are adolescent boys presenting with gynecomastia. Other diagnoses such as galactocele(s), hemangiomas, and ductal ectasia should be considered when young male patients present with a palpable mass. Malignant breast lesions are rare and are likely to be metastatic or primary tumors of nonbreast tissue origin.     

Nasopharyngeal carcinoma with splenic and cystic liver metastases in a pediatric patient: 18F-FDG PET-CT findings

Pediatric nasopharyngeal carcinoma (NPC) is rare and usually poorly differentiated. We report a 14-year-old boy with NPC with metastases to liver, spleen, lymph nodes and bone marrow. The liver metastases closely resembled benign cystic liver disease on imaging; however, they showed intense uptake similar to other metastatic sites on positron emission tomography (PET) scan. A liver biopsy could not be performed on the boy. The boy responded clinically to platinum-based chemotherapy, and all the baseline PET-positive lesions became negative. This case highlights the rarity of splenic and cystic liver metastases in pediatric NPC and demonstrates the potential use of PET/CT in diagnosis, staging and response assessment in metastatic pediatric NPC.     

Malignant melanoma in children: imaging spectrum

Objective. The objective of this study was to investigate the role of diagnostic imaging in detecting unsuspected metastatic disease in children with malignant melanoma. This has not been well studied previously. Materials and methods. We correlated imaging findings of 33 children diagnosed with melanoma with the level of invasion and clinical stage of disease. Results. Clinically undetectable metastases were identified in eight patients (25 %), four of whom had multiple metastases. All eight patients had deep lesions (Clark's level IV or V) or unknown primary sites of disease. Conclusion. Children with thick melanomas and those with unknown site of primary tumors are at increased risk of having clinically unsuspected metastases and should undergo CT of the chest, abdomen, and local-regional nodal basins at diagnosis to determine disease extent.     

Whole-body MRI of Langerhans cell histiocytosis: comparison with radiography and bone scintigraphy

Background In Langerhans cell histiocytosis (LCH) evaluation of the extent of disease is one of the major predictors of patient outcome. Historically this is undertaken using plain radiography and bone scintigraphy. Recently, whole-body (WB) MRI has been reported to be useful in detecting skeletal and extraskeletal metastases in both adults and children. Objective To evaluate the usefulness of WB MRI in patients with LCH in comparison with plain radiography and bone scintigraphy. Materials and methods In nine children (1–7 years of age; mean 3.3 years) who had a pathological diagnosis of LCH and had either plain radiography or bone scintigraphy for comparison, 43 WB MR examinations were performed. Skeletal and extraskeletal lesions of the disease on WB MRI were compared with those on plain radiography and bone scintigraphy. Results LCH showed unifocal single-system involvement in one patient, multifocal single-system involvement in three, and multifocal multisystem disease in five. WB MRI identified additional skeletal lesions in three (38%) of eight patients, compared with plain radiography, and in two (25%) of eight, compared with bone scintigraphy. WB MRI detected extraskeletal lesions of the disease in five (56%) of the nine patients exclusively, except for one patient whose lung lesions were also detected on plain radiography. In two patients, treatment was changed according to WB MRI findings. Conclusion WB MRI is a useful initial and follow-up diagnostic method to assess the extent of LCH because WB MRI not only identifies more skeletal lesions of the disease than do plain radiography and bone scintigraphy, but also detects extraskeletal lesions of the disease.     

Malignant Melanocytic Lesions of Unknown Primary Site in Children and Adolescents

Background. Metastatic melanoma with an unidentified primary site represents 4% of all newly diagnosed cases of malignant melanoma in adults. Little is known of the incidence and clinicopathologic features of this clinical entity in the pediatric population. Methods. We reviewed all previously diagnosed cases of malignant melanoma in children and adolescents (<21 years) who were treated at our institution and identified three patients who presented with metastatic melanocytic lesions with an unidentified primary site. Results. This clinical presentation accounted for 9% of all malignant melanocytic lesions treated at our center over a 20-year period. The clinicopathologic features were similar to those seen in adults. Two patients died of progressive disease within two years of presentation; the third is alive and disease-free 18 years post-diagnosis. Conclusions. Although uncommon in the pediatric population, malignant melanoma should be considered in the differential diagnosis of poorly differentiated disseminated malignancy that involves lymph nodes or viscera with no identifiable primary tumor. © 1995 Wi1ey-Liss, Inc.     

Clinical breast concerns in low-risk pediatric patients: practice review with proposed recommendations

Background

Fibroadenoma is overwhelmingly the most common pediatric breast lesion. Breast malignancy is quite uncommon in children, most frequently metastatic or hematological malignancy. Core biopsy has largely replaced excision for diagnosis of breast masses in adults.

Objective

The purpose of this study is two-fold: (1) compare utilization at our institution of interventional procedures vs. surgery for breast mass diagnosis in patients ≤18 years and (2) propose guidelines for breast imaging and biopsy in this population.

Materials and methods

We extracted data for all patients ≤18 who, between 2004 and 2016, underwent either (a) imaging and/or intervention procedure, or (b) breast surgery, from the Radiology Information System and Pathology Data System, respectively. We recorded age, gender, imaging, procedure, lesion size and histopathology.

Results

We found 1,050 pediatric patients ≤18 years who underwent diagnostic breast ultrasound between 2004 and 2016. Of these, 168 patients underwent 199 interventional procedures. One hundred thirty patients underwent 160 core biopsies of solid lesions. Core biopsy pathology diagnosed benign lesions in 99%, of which 84.3% were fibroadenomas (n=135). One malignancy was diagnosed, B cell lymphoma. Two hundred three patients underwent surgical excision for 266 discrete lesions, and 89% were fibroadenomas. Seven benign phyllodes tumors were surgically diagnosed. No malignancies were diagnosed.

Conclusion

Core biopsy in patients 18 years and younger is well-tolerated, has few risks, and is preferable to surgery in developing breasts, but the goal is to avoid any breast procedure whenever possible. We propose guidelines for pediatric breast imaging, follow-up, core biopsy and excisions.

     

The feasibility of implementing a communication skills training course in pediatric hematology/oncology fellowship

Communication skills are a competency highlighted by the Accreditation Council on Graduate Medical Education; yet, little is known about the frequency with which trainees receive formal training or what programs are willing to invest. We sought to answer this question and designed a program to address identified barriers. We surveyed pediatric fellowship program directors from all disciplines and, separately, pediatric hematology/oncology fellowship program directors to determine current use of formal communication skills training. At our institution, we piloted a standardized patient (SP)-based communication skills training program for pediatric hematology/oncology fellows. Twenty-seven pediatric hematology/oncology program directors and 44 pediatric program directors participated in the survey, of which 56% and 48%, respectively, reported having an established, formal communication skills training course. Multiple barriers to implementation of a communication skills course were identified, most notably time and cost. In the pilot program, 13 pediatric hematology/oncology fellows have participated, and 9 have completed all 3 years of training. Precourse assessment demonstrated fellows had limited comfort in various areas of communication. Following course completion, there was a significant increase in self-reported comfort and/or skill level in such areas of communication, including discussing a new diagnosis (p =.0004), telling a patient they are going to die (p =.005), discussing recurrent disease (p <.001), communicating a poor prognosis (p =.002), or responding to anger (p ≤.001). We have designed a concise communication skills training program, which addresses identified barriers and can feasibly be implemented in pediatric hematology/oncology fellowship.
