Abstract
The current evidence on paediatric melanoma is heterogeneous, especially regarding the prognosis of different histological subtypes. We sought to systematically review the evidence on paediatric melanoma, highlighting the major sources of heterogeneity and focusing on available data on single patients. A systematic search was performed from 1948 to 25 January 2021. Only studies reporting at least one case of cutaneous melanoma in patients aged ≤18 years were included. Unknown primary and uncertain malignant melanomas were excluded. Three couples of authors independently performed title/abstract screening and two different authors reviewed all the relevant full texts. The selected articles were manually cross-checked for overlapping data for qualitative synthesis. Subsequently data on single patients were extracted to perform a patient-level meta-analysis. PROSPERO registration number: CRD42021233248. The main outcomes were melanoma-specific survival (MSS) and progression-free survival (PFS) outcomes. Separate analyses were done of cases with complete information on histologic subtype, focusing on superficial spreading (SSM), nodular (NM) and spitzoid melanomas, as well as of those classified as de-novo (DNM) and acquired or congenital nevus-associated melanomas (NAM). The qualitative synthesis covered 266 studies; however, data on single patients were available from 213 studies including 1002 patients. Among histologic subtypes, NM had a lower MSS than both SSM and spitzoid melanoma, and a lower PFS than SSM. Spitzoid melanoma had a significantly higher progression risk than SSM and trended toward lower mortality. Focusing on nevus-associated status, DNM demonstrated better MSS after progression than congenital NAM, and no differences were highlighted in PFS. Our findings describe the existence of different biological patterns in paediatric melanoma. Specifically, spitzoid melanomas demonstrated intermediate behaviour between SSM and NM and showed a high risk of nodal progression but low mortality. This raises the question of whether spitzoid lesions are being over-diagnosed as melanoma in childhood.

Abstract
BACKGROUND Regional lymph node metastasis (RLNM) occurs infrequently in patients with soft tissue sarcoma (STS), although certain STS subtypes have a higher propensity for RLNM. The identification of RLNM has significant implications for staging and prognosis; however, the precise impact of node-positive disease on patient survival remains a topic of controversy. Although the benefits of sentinel lymph node biopsy (SLNB) are well documented in patients with melanoma and breast cancer, whether this procedure offers a benefit in STS is controversial. METHODS A systematic literature search was performed and articles reviewed to determine if SLNB in patients with extremity/truncal STS impacts disease-free or overall survival. RESULTS Six studies were included. Rates of sentinel lymph node positivity were heterogeneous (range 4.3-50%). The impact of SLNB on patient outcomes remains unclear. The overall quality of available evidence was low, as assessed by the Grading of Recommendations, Assessment, Development, and Evaluation system. CONCLUSIONS The literature addressing the impact of nodal basin evaluation on the staging and management of patients with extremity/truncal STS is confounded by heterogeneous patient cohorts and clinical practices. Multicenter prospective studies are warranted to determine the true incidence of RLNM and whether SLNB could benefit patients with clinically occult RLNM at diagnosis.

Abstract
INTRODUCTION Although the sentinel lymph node Biopsy (SLNB) is well stablished in solid tumors among adults but the experience on SLNB in pediatrics is still limited. In this article we report our experience of sentinel lymph node detection that is applied on pediatric solid renal tumors. MATERIAL AND METHODS Twenty 1-16 year old children with non-metastatic primary Wilms tumor regarding the radiological studies were enrolled. Radio tracer injection was carried out after renal vein, artery and ureter ligation, at the time of radical nephrectomy. Sentinel node detection and sampling was performed in every location with radiotracer count of 3 times more than background. Finally lymph node sampling was completed following the standard current discipline in Wilms tumor surgery. RESULTS A single SLN was detected in 16 patients. 4 patients had more than one SLN. The most common site of SLN was inter aortocaval space. Histopathologic studies revealed tumor involvement in 3 sentinel nodes (15%). All other lymph node samples were also studied histologically and LN involvement was not detected in any of the cases with tumor free sentinel lymph node (no false negative case). Multiple LN involvement was reported in two patients with positive SLN in which, other involved lymph nodes were removed with the tumor during radical nephrectomy. CONCLUSION Intraoperative SLNB is a safe and feasible tool to improve the accuracy of staging in pediatric Wilms' tumor. We suggest to ligate renal artery and vein prior to radiotracer injection to diminish the background confounding effect. LEVEL OF EVIDENCE Level II (development of diagnostic criteria in a consecutive series of patients and a universally applied "gold standard") TYPE OF STUDY: Study of Diagnostic Test.

Abstract
Background Our aim is to show whether the sentinel node procedure (SNP) is recommendable for pediatric patients with extremity rhabdomyosarcoma (RMS). Lymph node metastases are an important prognostic factor in pediatric patients with extremity RMS. Accurate nodal staging is necessary to treat the patient accordingly. An alternative to the current recommended lymph node sampling is the sentinel node procedure (SNP). Methods A systematic review was performed summarizing all published cases of SNP in addition to 13 cases from our hospital and 8 cases from two other hospitals that have not been published before. Results For all patients (n = 55), at least one SLN was identified, but the SNP technique used was not uniform. The SNP changed the nodal classification of eight patients (17.0%) and had a false-negative rate of 10.5%. Conclusions The SNP is recommendable for pediatric patients with extremity RMS. It can change lymph node status and can be used to sample patients in a more targeted way than nodal sampling alone. Therefore, we recommend use of the SNP in addition to clinical and radiological nodal assessment for pediatric patients with extremity RMS.

Abstract
BACKGROUND/PURPOSE Lymphadenopathy is a common complaint in children. Pediatric surgeons are often called upon to evaluate, treat, and/or biopsy enlarged lymph nodes. With many nonsurgical causes in the differential diagnosis, the surgeon plays the important role of providing reassurance and timely diagnosis while minimizing the pain and morbidity associated with surgical interventions in children. The purpose of this summary paper is to provide a management guide for surgeons working up children with lymphadenopathy. MATERIALS/METHODS The English language literature was searched for "lymphadenopathy in children". All manuscript types were considered for review, regardless of medical specialty, with emphasis placed on published guidelines, algorithms, and reviews. After thorough review of these manuscripts and cross-referencing of their bibliographies, the attached algorithm was developed, with emphasis on the role and timing of surgical intervention. RESULTS The APSA Cancer Committee developed the attached algorithm to fill a gap in the surgical literature. It outlines lymphadenopathy workup and treatment with emphasis on the role and timing of surgical intervention. CONCLUSION This review defines and summarizes the common etiologies and presentations of lymphadenopathy in children, and offers a straightforward algorithm for evaluation of and treatment with an emphasis on malignancy risk and surgical management.

Abstract
PURPOSE The aim of this study was to evaluate outcomes based on surgical approach for retroperitoneal lymph node dissection (RPLND) in patients with paratesticular rhabdomyosarcoma (PT-RMS). METHODS Patients undergoing RPLND for PT-RMS over 10 years at a single institution were retrospectively reviewed. Length of stay (LOS), complications, oral morphine equivalents per kilogram (OME/Kg), lymph node yield, and time to chemotherapy were assessed. The surgical approaches compared were: open transabdominal, open extraperitoneal, laparoscopic, and retroperitoneoscopic. For cases with lymphatic mapping, indocyanine green (ICG) was injected into the spermatic cord. RESULTS Twenty patients were included: five open transabdominal, six open extraperitoneal, three laparoscopic, and six retroperitoneoscopic operations. LOS was shorter in the retroperitoneoscopic group than laparoscopic (p = 0.029) and both open groups (p < 0.001). Mean OME/kg used was lowest in the retroperitoneoscopic (0.13 ± 0.15) group compared to laparoscopic (0.68 ± 0.53, p = 0.043), open transabdominal (14.90 ± 8.87, p = 0.003), and extraperitoneal (10.11 ± 2.44, p < 0.001). Time to chemotherapy was shorter for retroperitoneoscopic patients (0.13 days ± 0.15) compared to open transabdominal (15.6 days±6.5, p = 0.005). There was no difference in lymph node yield between groups. Spermatic cord ICG demonstrated iliac lymph node avidity on near-infrared spectroscopy. CONCLUSIONS Minimally invasive RPLND appears to offer a faster recovery without compromising lymph node yield for patients with PT-RMS. LEVEL OF EVIDENCE III.

Abstract
The pediatric melanoma population is not well described, and current guidelines for their management are not well defined. Our study aims to identify this population, treatment modalities, and outcomes using a national population-based database. We reviewed the Surveillance, Epidemiology, and End Results database (2004–2008). Patients ≤21 years old with melanoma were included and grouped into ≤12 years of age, 13 to 18 years, and 19 to 21 years. Clinical characteristics were analyzed across the groups. A total of 1255 patients were included: 52.7 per cent were 19 to 21 years of age, 36.3 per cent were 13 to 18 years of age, and 11.0 per cent were ≤12 years of age. The 19- to 21-year-olds had the highest proportion of stage I (50.5%) versus ≤12 years of age (31.9%); the ≤12-year-olds had the highest proportion of stage IV (3.6%) versus 19 to 21 years of age (0.9%), P < 0.001. The 19- to 21-year-olds had the highest proportion receiving wide local excisions only (34.8%) versus ≤12 years of age (26.4%); the ≤12-year-olds had the highest proportion of patients without any surgeries (16.0%) versus 13 to 18 years of age (9.4%), P = 0.169. On adjusted analysis, the 19- to 21-year-olds had worse survival compared with ≤12 years of age (hazard ratio: 5.26, P = 0.017, 95% confidence interval 1.34–20.65). Disparities were found in the ≤12-year-old melanoma population, as they had later stage melanomas, less invasive surgery, and lower survival. Clearer prognostic factors are needed to better elucidate their management.

Abstract
BACKGROUND Lymphatic mapping to guide sentinel lymph node biopsy (SLNB) typically requires lymphoscintigraphy prior to surgery. In young pediatric patients, this process often requires intubation in the nuclear medicine suite followed by transport to the operating room (OR). METHODS We reviewed 14 pediatric cases in which a portable nuclear imaging camera was utilized to perform the entirety of the SLNB in the OR. RESULTS AND CONCLUSION This method, utilizing intraoperative nuclear imaging, helped to confirm removal of the sentinel lymph node in real time, decreased anesthesia time, and avoided transport of a sedated or intubated child.

Abstract
BACKGROUND Lymph node metastases are an important cause of treatment failure for pediatric and adolescent/young adult (AYA) sarcoma patients. Nodal sampling is recommended for certain sarcoma subtypes that have a predilection for lymphatic spread. Sentinel lymph node biopsy (SLNB) may improve the diagnostic yield of nodal sampling, particularly when single-photon emission computed tomography/computed tomography (SPECT-CT) is used to facilitate anatomic localization. Functional imaging with positron emission tomography/computed tomography (PET-CT) is increasingly used for sarcoma staging and is a less invasive alternative to SLNB. To assess the utility of these 2 staging methods, this study prospectively compared SLNB plus SPECT-CT with PET-CT for the identification of nodal metastases in pediatric and AYA patients. METHODS Twenty-eight pediatric and AYA sarcoma patients underwent SLNB with SPECT-CT. The histological findings of the excised lymph nodes were then correlated with preoperative PET-CT imaging. RESULTS A median of 2.4 sentinel nodes were sampled per patient. No wound infections or chronic lymphedema occurred. SLNB identified tumors in 7 of the 28 patients (25%), including 3 patients who had normal PET-CT imaging of the nodal basin. In contrast, PET-CT demonstrated hypermetabolic regional nodes in 14 patients, and this resulted in a positive predictive value of only 29%. The sensitivity and specificity of PET-CT for detecting histologically confirmed nodal metastases were only 57% and 52%, respectively. CONCLUSIONS SLNB can safely guide the rational selection of nodes for biopsy in pediatric and AYA sarcoma patients and can identify therapy-changing nodal disease not appreciated with PET-CT.

Abstract
BACKGROUND/PURPOSE Sentinel lymph node biopsy (SLNB)-based management has been shown to improve disease-free survival in adult melanoma, but there is scant evidence regarding the utility of SLNB in pediatric melanoma. METHODS The 2004-2011 Surveillance, Epidemiology, and End Results database was queried for patients with primary cutaneous melanoma of Breslow depth>0.75mm and clinically negative nodes. Pediatric patients, defined as less than 20years of age, were grouped by whether they underwent SLNB or not. Kaplan-Meier analysis was performed to compare melanoma-specific survival (MSS) in propensity-matched groups. RESULTS 310 pediatric patients met study criteria: 261 (84%) underwent SLNB, while 49 (16%) did not. There was no difference in MSS between matched children who received SLNB and those who did not (p=0.36). Among children who received SLNB, a positive SLNB was associated with worse MSS compared to a negative SLNB (89% vs. 100% at 84months, p=0.04). However, children with a positive SLNB had more favorable survival compared to patients >20years of age (88% vs. 66% at 84months, p=0.02). CONCLUSIONS SLNB does not confer a survival benefit to children with melanoma, but it provides valuable prognostic information regarding MSS.

Abstract
In recent years, advances in molecular genetic characterisation have revealed that atypical Spitz tumours (ASTs) are basically heterogeneous diseases, although the clinical relevance of these findings is yet to be determined. Evidence of molecularly-defined diverse groups of lesions continues to accumulate; however, conflicting, confusing, and overlapping terminology has fostered ambiguity and lack of clarity in the field in general. The lack of fundamental diagnostic (morphological) unambiguous classification framework results in a number of challenges in the interpretation of the molecular genetic data. In this review, we discuss the main difficulties for pathologists and clinicians in the complex management of ASTs, with particular emphasis on the different genetic and biological features of recently-described entities, and offer our view of what could be medically reasonable to guide a rational approach in light of current data.

Abstract
Pediatric soft tissue sarcomas are a group of malignant neoplasms arising within embryonic mesenchymal tissues during the process of differentiation into muscle, fascia and fat. The tumors have a biphasic peak for age of incidence. Rhabdomyosarcoma (RMS) is diagnosed more frequently in younger children, whereas adult-type non-RMS soft tissue sarcoma is predominately observed in adolescents. The latter group comprises a variety of rare tumors for which diagnosis can be difficult and typically requires special studies, including immunohistochemistry and molecular genetic analysis. Current management for the majority of pediatric sarcomas is based on the data from large multi-institutional trials, which has led to great improvements in outcomes over recent decades. Although surgery remains the mainstay of treatment, the curative aim cannot be achieved without adjuvant treatment. Pre-treatment staging and risk classification are of prime importance in selecting an effective treatment protocol. Tumor resectability, the response to induction chemotherapy, and radiation generally determine the risk-group, and these factors are functions of tumor site, size and biology. Surgery provides the best choice of local control of small resectable tumors in a favorable site. Radiation therapy is added when surgery leaves residual disease or there is evidence of regional spread. Chemotherapy aims to reduce the risk of relapse and improve overall survival. In addition, upfront chemotherapy reduces the aggressiveness of the required surgery and helps preserve organ function in a number of cases. Long-term survival in low-risk sarcomas is feasible, and the intensity of treatment can be reduced. In high-risk sarcoma, current research is allowing more effective disease control.

Abstract
BACKGROUND The use of nuclear medicine for the management of malignant tumor, such as radioguided surgery and sentinel lymph node biopsy (SLNB), has been widely accepted in the adult practice. However, there are very few studies to apply those techniques for pediatric diseases. The aim of this study was to investigate the feasibility of application of nuclear medicine in surgery for neuroblastoma (NB) or rhabdomyosarcoma (RMS) in children. METHODS Radioguided surgery using (123) I-metaiodobenzylguanidine was performed on six children with NB. SLNB using technetium-labeled tin or sulfur colloid was performed on two children with perineal RMS. Histological evaluation of resected specimens was performed to determine the accuracy of intraoperative detection and SLNB. All patients were evaluated for overall survival and complications. RESULTS Intraoperative tumor localization using hand-held gamma probe was helpful in 85.7% of NB patients. Sensitivity and specificity of this technique were 81.8% and 93.3%, respectively. There were no postoperative complications, and four out of five patients with high-risk NB experienced disease-free survival (median follow up, 57 months). Sentinel lymph nodes were easily detected in patients with perineal RMS, and histological assessment revealed complete consistency with regional lymph node status. CONCLUSIONS Nuclear medicine may have a potential application in the use of less invasive surgery for advanced NB or perineal RMS, the two most challenging pediatric malignancies.

Abstract
BACKGROUND Diagnosis and proper management of atypical Spitz tumors in pediatric age are still controversial. OBJECTIVE We sought to investigate the clinicopathological and molecular features of atypical Spitz tumors in patients aged 18 years or younger. METHODS We performed a retrospective clinicopathological and fluorescence in situ hybridization study on 50 pediatric atypical Spitz tumors. RESULTS Parameters that were significantly correlated with a diagnosis of atypical Spitz tumors over Spitz nevus included asymmetry, level IV/V, lack of maturation, solid growth, nuclear pleomorphism, high nuclear-cytoplasmic ratio, atypical and deep mitoses, and more than 6 mitoses/mm(2). In the atypical Spitz tumors group, a significantly higher mitotic rate was observed in prepuberal age (P = .04). The 4-probe fluorescence in situ hybridization melanoma assay did not discriminate atypical Spitz tumors from Spitz nevi. Heterozygous 9p21 loss was found in 3 of 37 cases and homozygous 9p21 loss in 2 of 37 cases. Only 1 child experienced a fatal outcome, showing genetic abnormalities by melanoma fluorescence in situ hybridization probe and a heterozygous 9p21 deletion. LIMITATIONS The limited number of adverse outcomes did not allow the prognostic analysis of single morphologic features. CONCLUSION Pediatric atypical Spitz tumors are associated with minimal lethal potential. Atypical Spitz tumors require complete excision and careful follow-up while our data do not support any clinical benefit for the sentinel lymph node biopsy procedure and completion lymphadenectomy.

Abstract
Atypical cutaneous melanocytic lesions, including those with Spitzoid features, can be difficult to categorize as benign or malignant. This can lead to suboptimal management, with potential adverse patient outcomes. Recent studies have enhanced knowledge of the molecular and genetic biology of these lesions and, combined with clinicopathological findings, is further defining their biological spectrum, classification, and behavior. Sentinel node biopsy provides important prognostic information in patients with cutaneous melanoma, but its role in the management of melanocytic lesions of uncertain malignant potential (MELTUMP) is controversial. This paper examines the role of molecular testing and sentinel node biopsy in MELTUMPs, particularly atypical Spitzoid tumors.

Abstract
BACKGROUND The purpose of this study was to report our experience with sentinel lymph node biopsy (SLNB) for pediatric soft tissue sarcomas to add to the limited literature about its feasibility, utility, and concordance with pre-operative imaging, including CT and (18)F-FDG PET (PET) scanning. METHODS Medical records of patients with a sarcoma who underwent SLNB as part of their treatment for a soft tissue sarcoma at our institution from 2000 to 2011 were identified and reviewed. RESULTS Eight patients underwent SLNB for soft tissue sarcoma during the study period. Two patients had positive SLNBs; both of these patients had rhabdomyosarcoma. Three patients with pathologically enlarged lymph nodes on CT scan underwent PET functional imaging prior to SLNB. The PET suggested the presence of nodal disease in all three patients; however, only one of these patients had a positive SLNB. CONCLUSIONS Our series confirms that SLNB is feasible in pediatric sarcoma patients. Small numbers preclude definitive conclusions regarding the utility of SLNB compared with PET, however our data suggest functional imaging alone may not be sufficient to definitively determine lymph node status in these patients. Surgical lymph node sampling may still need to be performed to accurately identify nodal status in pediatric patients with soft tissue sarcoma.

Abstract
PURPOSE The purpose of this study was to characterize the complications associated with surgical treatment of pediatric melanoma. METHODS We retrospectively reviewed all pediatric patients who received surgical treatment for melanoma at our institution between 1992 and 2010. We compared complications between three groups: wide local excision only (WLE), WLE and sentinel lymph node biopsy (SLNB), and WLE and completion lymph node dissection (CLND). RESULTS One hundred twenty-five patients were identified: 37 patients received WLE only, 47 received WLE and SLNB, and 41 patients had WLE and CLND. Complication rates differed between the three groups: 19% in WLE, 11% in WLE+SLNB, and 39% in WLE+CLND (P=.006). The risk of complications was significantly lower among patients having WLE+SLNB versus WLE+CLND (OR 0.19, 95% CI 0.06-0.57, P=.0032). Lymphedema was a common complication with a higher incidence in the CLND group compared to the SLNB group (19.5% vs. 2.1%, P=.01). Complications were more frequent in inguinal compared to axillary dissections (52.0% vs. 17.1%, P=.006). CONCLUSIONS In the surgical treatment of pediatric melanoma, the addition of a completion lymph node dissection significantly increases complication risk. Thus, it is critical to determine which patients truly benefit from this procedure.

Abstract
PURPOSE The purpose of this study was to describe the use of lymphoscintigraphy and sentinel lymph-node biopsy (SLNB) for the management of children with melanoma and sarcomas. We report the experience of two children's hospitals that utilize this technique to identify sentinel lymph nodes for lymph-node biopsy and dissection. METHODS We identified 56 patients (median age 10.8 years) who underwent 58 lymphoscintigraphy procedures. There were 33 patients with melanoma and melanocytic lesions, and 23 with sarcomas. RESULTS Of 58 lymphoscintigraphy procedures, sentinel lymph nodes were identified in 52 (90% success rate). Using the combination of intraoperative blue dye injection and lymphoscintigraphy, the success rate was 95% (55/58). Metastatic disease was found in 14 sentinel lymph nodes (13 patients with melanoma and melanocytic lesions, and 1 patient with rhabdomyosarcoma). CONCLUSION We have found that lymphoscintigraphy with SLNB is an effective method to identify patients who may benefit from more extensive lymph-node dissection and to identify those patients who are unlikely to benefit from further lymph-node exploration.

Abstract
Rhabdomyosarcoma (RMS) is a malignant childhood tumor of mesenchymal origin that currently has a greater than 70% overall 5-year survival. Multimodality treatment is determined by risk stratification according to pretreatment stage, postoperative group, histology, and site of the primary tumor. Pretreatment staging is dependent on primary tumor site, size, regional lymph node status, and presence of metastases. Unique to RMS is the concept of postoperative clinical grouping that assesses the completeness of disease resection and takes into account lymph node evaluation. At all tumor sites, the clinical grouping, and therefore completeness of resection, is an independent predictor of outcome. Overall, the prognosis for RMS is dependent on primary tumor site, patient age, completeness of resection, extent of disease, including the presence and number of metastatic sites and histology and biology of the tumor cells. Therefore, the surgeon plays a vital role in RMS by contributing to risk stratification for treatment, local control of the primary tumor, and outcome. The current state-of-the-art treatment is determined by treatment protocols developed by the Soft Tissue Sarcoma Committee of the children's Oncology Group.

Abstract
For dermatologists, evidence-based management guidelines for Spitz tumors have not been established. Despite the lack of a standardized approach, most dermatologists recommend the excision of Spitz tumors occurring in adults and adopt more conservative measures towards pediatric cases. The histopathologic attributes and the clinical scenario are factored into management in each case. While the metastatic behavior of certain Spitz tumors is well known, the malignant potential of these lesions remains unclear because they only rarely result in negative outcomes. The risks and benefits of adjunctive measures, such as sentinel lymph node biopsy and interferon use, remain untested and are subjects of ongoing controversy. (In part II of this continuing medical education article, we will continue to use the terminology defined in part I for purposes of continuity. "Spitz tumor" is used as the umbrella term for the entire category of lesions, "common Spitz nevi" refers to only the most typical lesions seen in pediatric cases, and "atypical Spitz tumors" encompass the "all other" category, which continues to cause debate.).

Abstract
Identification of nodal involvement is important for treatment planning in patients with rhabdomyosarcoma, and is facilitated by sentinel node biopsy. Although it is employed primarily for extremity tumors, we report using sentinel node biopsy in a patient with parameningeal rhabdomyosarcoma arising in the ethmoid sinus. Lymphoscintigraphy with single photon emission computed tomography following injection of tracer at the tumor site helped identify contralateral cervical node involvement not previously recognized by physical exam, cross sectional imaging, or other functional imaging. This case demonstrates how information from sentinel node identification and biopsy can change therapy recommendations in patients with parameningeal rhabdomyosarcoma.

Local recurrence and assessment of sentinel lymph node biopsy in deep soft tissue leiomyosarcoma of the extremities. Clin Sarcoma Res 2011; 1:7. [PMID: 22612847 PMCID: PMC3351718 DOI: 10.1186/2045-3329-1-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2011] [Accepted: 08/01/2011] [Indexed: 01/22/2023] Open
Abstract
Background Leiomyosarcoma of deep soft tissues of the extremities is a rare malignant tumour treated primarily by surgery. The incidence of local recurrence and lymph node metastasis is uncertain and it is not known whether a sentinel lymph node biopsy is indicated in these tumours. Methods A retrospective review of patients treated for extremity deep soft tissue leiomyosarcoma at our institution over a 10-year period was conducted. Patients developing local recurrence or lymph node metastasis were identified. The presence or absence of lymphatics in the primary tumours was assessed by immunohistochemical expression of LYVE-1 and podoplanin. Results 27 patients (mean age 62 years) were included in the study. 15 were female and 12 male. Lymph node metastasis was seen in only two cases (7%); intratumoural lymphatics were identified in the primary tumours of both these cases. Local recurrence occurred in 25.9% of cases despite complete excision and post-operative radiotherapy; the mean time to recurrence was 10.1 months. Conclusion On the basis of this study, we do not advocate sentinel lymph node biopsy in this group of patients except in those cases in which intratumoural lymphatics can be demonstrated. Close follow up is important especially for high grade leiomyosarcomas, particularly in the first year, as these tumours have a high incidence of local recurrence.

Abstract
PURPOSE OF REVIEW We will review the 2007/2008 literature on pediatric genitourinary tumors. RECENT FINDINGS Newly identified constitutional epigenetic defects in Wilms tumor genes extend the understanding of Wilms tumor risk in children lacking syndromic features, and add to the complexity of the pathogenesis of these tumor suppressor genes. Pediatric renal cell carcinoma has distinct molecular characteristics and clinical associations from the adult counterpart. The pathway from PAX3-FKHR translocation to the development of rhabdomyosarcoma tumors has been further elucidated. SUMMARY Therapeutic strategies continue to be driven by developments in molecular diagnostics in pediatric genitourinary tumors.
