RESUMEN

BACKGROUND: Non-prostatic bed recurrence of prostate cancer (PCa) is usually treated with androgen deprivation therapy (ADT). We analyzed the impact of salvage extended lymph node dissection (sLND) on cancer control in patients with rising PSA and lymph node (LN) metastases. METHODS: Between 2009 and 2016 we performed sLND in 87 patients with biochemical recurrence (BCR) and positive LNs on 18FEC and 68Ga-PSMA positron emission tomography/X-ray computer tomography (PET/CT) after primary treatment (PT) of PCa. Intra- and postoperative complications according to Clavien-Dindo were assessed and the rates of biochemical response (BR), BCR-free and clinical recurrence (CR)-free survival, as well as time to initiation of systemic treatment were evaluated. RESULTS: Mean age of patients and mean PSA at sLND was 66.7 years (46-80 years) and 2.63 ng ml-1 (1.27-3.75 ng ml-1), respectively. With 87.4% radical prostatectomy (RP) was the most common PT. In all, 57.9% of patients additionally underwent adjuvant/salvage radiation therapy (RT) and 18.4% received ADT before sLND. Complete BR (cBR) was diagnosed in 27.5% of patients and incomplete BR in 40.6%. In total, 62.2% of patients remained without ADT at follow-up. With a median follow-up of 21 months (1-75 months), the cancer-specific mortality rate was 3.7%. The 3-year BCR-free, systemic therapy-free and CR-free survival rates for patients with cBR were 69.3%, 77.0% and 75%, respectively. CONCLUSIONS: sLND can be performed without significant complications and achieves an immediate BR, thus allowing a significant postponement of systemic therapy in selected patients with BCR and nodal recurrence of PCa. Therefore, sLND following 68Ga-PSMA PET/CT should be considered as part of a multimodal diagnostic and treatment concept for selective patients.

RESUMEN

BACKGROUND: The aim of this study was to evaluate the perioperative oncological and functional outcomes after robot-assisted radical prostatectomy (RALP) in older men. PATIENTS AND METHODS: The records of n = 2,000 men who underwent RALP from February 2006 to April 2010 were retrospectively reviewed. A total of 45 patients ≥ 75 years were indentified. Subsequently this subgroup was compared to the overall patient cohort with regard to perioperative results, pathological tumor stage, functional outcomes after 12 months and the prostate cancer-specific mortality and biochemical recurrence free survival. RESULTS: The following results reflect the comparison of the cohort of patients who were ≥75 years of age versus the overall cohort of patients. A statistical difference of the parameters analyzed was observed only for minor complications 15.5 % versus 11.4 % (p<0.05), neurovascular bundle (NVB) preservation 51.1 % versus 65.7 % (p<0.05) and potency after 12 months 39.6 % versus 66.2 % (p<0.001). Major complications were noted in 2.2 % versus 1.3 % of cases. A Gleason score <7 was noted in 37.4 % versus 42.8 %, a Gleason score 7 in 51.1 % versus 47.7 % and a Gleason score >7 in 11.6 % versus 9.5 %. Tumor stages pT2 and pT3 were noted in 68.8 % versus 73.5 % and in 31.2 % versus 25.2 %, respectively. The positive surgical margin status was encountered in 11.1 % versus 8.9 % of cases, respectively. At 12 months 86.9 % versus 92.8 % of patients were continent and 39.6 % versus 66.2 % were potent, respectively. After a median follow-up of 17.2 months the prostate cancer-specific mortality in the subgroup of elderly patients was 0 % and the biochemical recurrence-free survival was 95.5%. CONCLUSIONS: The RALP approach in patients ≥75 years of age is a safe surgical procedure with a limited complication rate, excellent oncologic and continence outcomes as well as acceptable erectile function. Nevertheless, RALP should be limited to a selected cohort of patients with a good health status and an individual life expectancy of more than 10 years. For the assessment of the final oncological benefits of RALP in this patient population a longer follow-up is necessary.

RESUMEN

The increasing experience obtained through laparoscopy has resulted in the evolution of ablative and reconstructive procedures in the field of paediatric urology. Apart from the established methods of laparoscopic nephrectomy and orchidopexy, nowadays laparoscopic hemi-nephrectomy and pyeloplasty have become standard therapeutic surgical alternatives. Nevertheless, many of these procedures require a high level of experience in laparoscopic preparation and stitching techniques and are thus performed in institutions with greater laparoscopic experience. With the introduction and evolution of the robotic-assisted technique and the availability of smaller instruments and ports (8 and 5 mm), there has been an evolution in the spectrum of complex ablative and reconstructive procedures in the field of paediatric urology as well. Nevertheless, there is a lack of randomised trails and the literature available in this area consists manly of case reports. The purpose of this article is to present the current status and perspectives of robotic-assisted surgery in the field of paediatric urology.

RESUMEN

AIM: Functional disorders of micturition after rectal resection were investigated on an in-house patient collective. Because the neuro-anatomy of the small pelvis is very complex, the aim of this study was to evaluate the incidence and form of disorders in micturition. MATERIALS AND METHODS: A total of 536 patients were operated on for a rectal carcinoma during the period 2000 to 2004 at the Surgical University Clinic in Erlangen. Patients with a recurrent tumor and patients who died during the study were excluded (140 patients). All patients were retrospectively questioned on the pre-operative and postoperative bladder function using a standard questionnaire. RESULTS: The patient collective consisted of 167 males and 111 females with an average age of 63 years and a mean follow-up time of 2.6 years. Age (<65 years versus >65 years) was found not to play a significant role with respect to micturition (p>0.05). Of the patients 20 already had a pollakisuria before the operation and 63 patients after the operation. Also 9 patients already had a nycturia before the operation and 55 after the operation. An imperative urgency to urinate was experienced by 9 patients before and 47 after the operation. Stress incontinence grade I was present in 21 patients before the operation, grade II in 4 patients and grade III in 1 patient. Of the patients 43 complained of stress incontinence grade I after the operation, 20 patients of a grade II and 15 of a grade III. The postoperative quality of life was assessed as very limited by 57 patients and moderately limited by 85. CONCLUSIONS: Functional disorders of micturition after rectal resection in rectal cancer patients are commonly occurring complications which have received relatively little attention in the literature considering the clinical significance. Only few affected patients have received a urological treatment. Further studies are necessary, also experimental in nature, to understand the neuro-anatomy of the small pelvis in order to avoid intra-operative neurolesions as far as possible.

RESUMEN

The purpose of this study is to report our method in detecting prostate cancer (PCa) using an 18-core transrectal ultrasound (TRUS) prostate biopsy (PB) schema, in combination with additional targeted cores from suspicious images in conventional (e-cMRI) and functional (e-fMRI) endorectal magnetic resonance imaging (e-MRI) of the prostate. From 2004 to 2008, 260 consecutive patients with a clinical suspicion of PCa underwent PB and were prospectively studied. e-cMRI and e-fMRI was performed in all patients before PB. The patients were divided into two groups (A and B) according to the results of their radiological findings (group A=suspicious findings, group B=non-suspicious findings). After the images were processed, an 18-core TRUS-guided PB was performed. When a patient exhibited a suspicious site on e-cMRI and e-fMRI images, three additional targeted PBs were obtained from that site. In group A, 17.5% of PCa was detected by the 18-core PB and 56.5% of PCa was detected by the targeted cores. The overall PCa detection rate (18+targeted cores) was 73.9%. The overall specificity was 73.9%. In group B, overall false-positive detection rate reached 19.2%, with the overall sensitivity being 80.8%. The method described above is not only practical but also a promising modality in PCa detection. As seen, PCa was optimally detected when combining the 18-core and targeted-core PB schema together. Non-suspicious images do not rule out the probability of PCa, thus justifying a PB in these patients as well.

RESUMEN

INTRODUCTION: Urethral duplication is a rare anomaly that can occur in various forms. Urethral duplication must be diagnosed and adequately treated. Only if clinical complaints develop should surgical management be considered. PATIENTS AND METHODS: The aim of this study was to retrospectively analyze patients with congenital urethral duplication: age at the time of diagnosis, type of urethral duplication, diagnostic and therapeutic measures as well as clinical aftercare were evaluated. RESULTS: This homogeneous and selected cohort included nine male children. The average follow-up was 6.2 years. Seven children were symptomatic (77.7%). We found a double urethra with epispadias in four boys and with hypospadias in three boys and urethral duplication with perineal/anal meatus in one patient and normotopia in another patient. In two children without symptoms, the urethral duplication was an incidental finding during diagnostic work-up for other anomalies. Seven children had additional urological anomalies: one fusiform megalourethra, three urethral valves with hypospadias, and two epispadias. Two children without symptoms were managed conservatively. An open operation joining the urethras was performed in three children, and four boys underwent endoscopic treatment of the urethral duplication. Long-term results revealed normal continence in all of the children. One child exhibited recurrent urinary tract infections and late stricture, which was opened endoscopically in a second session. CONCLUSION: A surgical approach is only indicated in the presence of clinical complaints. There is no surgical gold standard. The decision is ultimately reached on an individual basis depending on the findings and anatomy in view of the rarity and variability of the clinical picture. The functional result is of foremost importance for the urethra that requires reconstruction, but the cosmetic aspect should be respected to the same extent. We present the results of our experience in treating children with this urological condition. At the same time larger (multicenter) studies are needed, which will make it possible to formulate guidelines for this rare anomaly.

RESUMEN

Penoscrotal elephantiasis is a symptom that can be caused by local but also by systemic disorders. When the changes are reversible, conservative measures such as physical and antiphlogistic approaches lead to success. In cases of irreversible penoscrotal elephantiasis, excision and amputation of the affected penoscrotal areas are recommended to eliminate the functional disturbances. In all manifestations it is important to prevent and treat those diseases known to cause elephantiasis.

RESUMEN

INTRODUCTION: Pasqualini's syndrome is an isolated, incretory functional disorder of the testes with a secondary Leydig cell insufficiency but, unlike Klinefelder's syndrome, with normal spermiogenesis and fertility. This unusual form of hypogonadism is caused by an inherent LH secretion disorder of the pituitary gland. The result of this is the secondary Leydig cell insufficiency and a corresponding peripheral androgen deficiency. In this communication we present the case of a 67-year-old man with Pasqualini's syndrome and a histologically confirmed left seminoma. In view of the current lack of data and our experience, we describe the properties of this uncommon syndrome; therapy, prognosis and possible relationship with seminoma are discussed in more detail. CASE REPORT: The 67-year-old male presented in our outpatient department with the urgent suspicion of a left testicular tumour as a painless swelling of the testis since about three months. In the case history we found a previously diagnosed hypogonadotropic hypogonadism, which is described in the literature as the so-called Pasqualini syndrome. On palpation, the left testis was about fist-size, scirrhous, mildly pressure sensitive and highly suspicious. Sonography of the testes revealed the enlarged left testis to be completely inhomogeneous with hypo- and hyperdense areas and large spatial requirements with unremarkable perfusion. On the basis of the clinically and sonographically supported diagnosis of a tumour of the left testis and inguinal exposure of the testes was performed. Intraoperative histology of a sample confirmed the diagnosis of a testicular tumour in the sense of a seminoma. A high left ablatio testis was carried out. DISCUSSION: The occurrence of testicular tumours of the seminoma type in association with Pasqualini's syndrome has not previously been described in the literature. Thus, we assume that the seminoma had occurred at this age independently of the Pasqualini syndrome. For the treatment of Pasqualini's syndrome not only hCG but also testosterone have been employed with success. The patient must continue therapy for his whole life. The results of interruption tests confirm that it is not a passing ailment but rather a persisting, endogenous disease. PRACTICAL CONCLUSIONS: Since the molecular genetics and genesis of this disease have not been clarified unambiguously, further clinical and experimental studies are necessary in order to better understand the disease. An increased risk of testicular tumours has not yet been observed on account of the small number of cases of Pasqualini's syndrome.

RESUMEN

BACKGROUND: Prostate cancer is the second leading cause of death among men in Western countries. Genetic alterations of the estrogen receptor gene are known to be indicative of a higher risk of this disease. The estrogen receptor gene is found as two subtypes, alpha and beta. In this study the estrogen receptor alpha and beta genes were tested in 2 human prostate cancer cell lines: the hormone-sensitive PC-EW and the hormone-independent PC-OR. MATERIALS AND METHODS: Genomic DNA was isolated from 2 cell lines from metastatic prostate adenocarcinoma in hetero-transplanted male athymic nude (nu/nu) Balb/c mice. Mutation screening was performed by sequencing of exons 1-8 and intron 1 of the human estrogen receptor gene alpha, and exons 1-9 of estrogen receptor gene beta. RESULTS: No point mutations were detected in the ER gene subtypes of either cell line. Polymorphisms were found of ER-alpha in exon 1, intron 1, exon 3, 4, 5, intron 6 and exon 8 and of ER-beta in intron 2 and exon 9. CONCLUSION: Point mutations of ER-alpha and -beta are not necessary for metastatic prostate cancer, alterations in different areas of the ER genes are more often found. These polymorphisms are a part of many genetic influences that accumulate to contribute to men's overall risk for developing prostate cancer.

RESUMEN

Penoscrotal elephantiasis is not an uncommon clinical picture that may arise as a symptom of many diseases; it is usually a sequela of a recurring inflammatory process, eczema or malignancy. Elephantiasis often occurs after radical operations in the pelvic region. Displacement of lymphatic pathways leads to a local edema which over the course of time may lead to a considerable increase in volume of the patient's genitals or other affected parts. The diagnosis of elephantiasis is not difficult. It is much more difficult to determine which disease has caused the obstruction of the lymphatic pathways. If it is a reversible stage, the object of treatment is to remove the obstruction and reinstate the physiological lymph flow. Conservative measures such as administration of anti-inflammatory drugs and diuretics, physical measures such as baths, massage, elevation of the affected parts and treatment of the underlying disease may be considered. On progression to irreversible elephantiasis a chronic lymphatic edema occurs for which conservative measures will be unsuccessful. For cases where physical and anti-inflammatory measures are unsuccessful, excision and amputation of the affected penoscrotal region is recommended in order to eliminate the functional dysfunction. We report on two cases of penoscrotal elephantiasis, one in a child and the other in an adult man.

RESUMEN

This case report describes a female patient with bladder exstrophy and chronic compensated renal insufficiency as it relates to the topic of urinary bladder augmentation using the stomach and cutaneous vesicostomy with a Mitrofanoff continent stoma. Due to complete congenital bladder exstrophy the patient underwent functional reconstructive surgery for cystoschisis and several revision procedures. Because of a low-capacity, low-compliance bladder with bilateral urinary stasis in the kidneys, temporary percutaneous renal fistulas were created on both sides. After the patient had declined any follow-up during her pubertal years, advanced bilateral renal damage ensued. In a state of compensated renal insufficiency with creatinine levels >2 mg/dl, the patient was offered surgery for placement of an incontinent bladder substitute as an ileal or colon conduit because of the progressive kidney damage with obstructive uropathy. Since the patient rejected any form of wet stoma despite several consultations, after adequate preparations were met, a gastrocystoplasty and Mitrofanoff cutaneous vesicostomy with an umbilical stoma and artificial umbilicoplasty were performed. The patient catheterizes herself six times daily and is under close urological/nephrological supervision.In exceptional cases, gastrocystoplasty is an alternative to construction of a neobladder from bowel segments. It is particularly indicated for patients with compensated or already poor kidney function. The interventions are associated with several specific complications. There have as yet been no reports of malignant degeneration inside the gastric portion used for augmentation or the urothelium exposed to stomach acid. However, pathological and precancerous alterations of mucous membranes have been observed, which should be regularly monitored by endoscopy/biopsy and warrant further long-term studies.

RESUMEN

BACKGROUND: Wilms' tumors are highly malignant tumors of the kidneys and are among the most frequent solid tumors of childhood, which are diagnosed for the most part before the 5th year. Various congenital anomalies are associated with a genetic predisposition and thus an increased risk of developing a Wilms' tumor. PATIENTS AND METHODS: As part of a retrospective analysis, the records from 1965 to 2003 of 66 patients with histologically confirmed Wilms' tumor were reviewed. The aim of this study was to determine the incidence and type of different urogenital malformations as well as the genetic mutations and overall survival in this patient group. RESULTS: The patient cohort comprised 66 patients with histologically confirmed Wilms' tumor: 35 male patients (53%) and 31 female patients (47%). The overall survival after 10 years was 89.4%. All patients underwent radical nephrectomy: transperitoneal approach in 63 and lumbar approach in 3 patients. Eleven (16.7%) patients had diverse urogenital anomalies. A cytogenetic investigation was performed in 38 patients that revealed no pathological findings. The results of molecular genetic testing of tumor specimens were available for seven patients: a genetic mutation was detected in one case (heterozygous mutation R394 in exon 9 of the WT1 gene) which had already been described in the literature in conjunction with Denys-Drash syndrome. Hemihypertrophy with Beckwith-Wiedemann syndrome was present in two (3%) patients. CONCLUSION: In patients with urogenital malformations and Wilms' tumor, it would be important to carry out further molecular genetic testing to identify possible WT1 gene mutations. Close interdisciplinary cooperation between urologists, specialists in human genetics, and pediatricians is imperative.

RESUMEN

INTRODUCTION: Endometriosis is a benign proliferation of discarded or ectopic endometrial mucus membranes which retain the histological features and biological reactions of uterine mucus membranes. This tissue is not capable of independent proliferation but is subject to the influence of estrogen progesterone. In this report we describe the clinical course of two patients with histologically proven endometriosis with participation of the uteral region and uronephrosis. CASE REPORT 1: Left-sided uronephrosis was diagnosed in a 36-year-old female during a sonographic examination for hypertension. Our gynaecologists obtained histological proof of endometriosis by laparoscopy. Two days after the laparoscopic detection of foci of endometriosis in the intestine, Douglas' pouch, ovaries as well as in the region of the left terminal ureter, a left percutaneous renal fistula was created under sonographic and radiological control. After resection of the afflicted section of the ureter, implantation of a new left ureter was performed by means of a psoas-hitch plasty. CASE REPORT 2: A 30-year-old female presented with a months-long history of dyspareunia, pain on palpation of the Douglas' pouch, occasional pain on bowel movements and back pain. In addition she had been trying for years to become pregnant. On sonography renal congestion grade III was detected. After admission and appropriate preparation, one week later an open laparotomy with lysis of intestinal as well as uterine adhesions, salpingectomy and, by the urologist, partial left uteral resection with new implantation by the psoas-hitch technique. CONCLUSIONS: Endometriosis of the urinary tract is a rare occurrence affecting 1 - 2 % of all endometriosis patients with the urinary bladder being the most commonly affected site. Endometriosis with involvement of the ureter is often diagnosed very late because of the rareness of this situation and its asymptomatic course. An individual therapy plan depending first of all on the patient's age, desire for children, and the extent of the endometriosis foci should always be attempted.

RESUMEN

BACKGROUND: Wilms' tumor is the most common renal tumor in childhood. Preoperative treatment is still under discussion. The aim of this study was to determine, using our own patient collective, the risk factors for and type of intraoperative complications which can occur. In addition, the influence of the surgical procedure and tumor size on the complications and survival rate was analyzed. METHODS AND MATERIALS: A total of 66 patients with Wilms' tumor were retrospectively analyzed. Evaluation included histology, size of the primary tumor as well as neoadjuvant and adjuvant chemotherapy. The total survival rate over periods of 5 and 10 years postoperatively were analysed using Kaplan-Meier survival probabilities. RESULTS: All patients underwent radical nephrectomy: 63 using the transperitoneal and three the lumbar approach. The tumors had a mean size of 9.8 cm (range 2.5-20.0). Twenty patients (30.3%) received neoadjuvant chemotherapy for tumor reduction, while 46 patients underwent surgery without preoperative chemotherapy. Complications occurred in eight patients (15.2%). In two, a the tumor ruptured under surgery, four patients developed an ileus and two suffered cardiac arrest. One patient had postoperative hypertonia and another an incisional hernia. All complications occurred with a tumor size >5 cm or in the patient group without neoadjuvant chemotherapy. The 10 year survival rate was 89.4%. CONCLUSIONS: The risk of complications is associated with the local size of the primary tumor. Through tumor reduction, neoadjuvant chemotherapy influences the expression of the such complications. Transperitoneal tumor nephrectomy is the method of choice in surgery for Wilms' tumors.

RESUMEN

Wilms' tumors develop from persistent, primitive metanephrogenic stem cells. Their biology and etiology in adults is still unknown even though remnants of primitive metanephrogenic tissue, which tends to malignancy, is suspected, and there are very few scientific studies on the biology of Wilms' tumors in adults. Such a tumor occurs at a rate of 0.2/million adults in Europe and the USA. In this article, we describe the course of the disease in two adults with histologically confirmed Wilms' tumors. Both patients underwent a radical nephrectomy followed by chemotherapy as indicated by the SIOP nephroblastoma study.

RESUMEN

Nephroblastoma is commonly a chance finding in a series of malformation syndromes. With a frequency of 4-8%, urogenital malformations are amongst the most common congenital anomalies in Wilms' tumor patients. For various congenital anomalies, there is a genetic predisposition and thus an increased risk of developing Wilms' tumor. The WT1 gene product (WT1 protein) usually regulates genes that play an important role in normal kidney development and in maintaining kidney function. If this gene has a functional change, then this role is no longer possible. The consequence is the development of nephrotic syndrome and possibly of a Wilms' tumor.

RESUMEN

Urethral duplication is a rare deformity which can present in various forms, commonly together with other congenital malformations. The embryological genesis is unknown. The isolated deformity is most often found in young males, while for young females it is very rare. We report the case of a 1.5 year old male child having a duplicate urethra with penopubic epispadias and dorsal penis deviation. The child, with known penopubic epispadias grade II and dorsal penis deviation, presented for pediatric urological consultation involving additional diagnostics and therapy. Examination revealed a penopubic epispadias with an external urethral exit at the base of the penis. A preoperative micturating cystogram led to the diagnosis of an accessory central as well as an epispadic urethra. We then carried out urethral reconstruction with the surgical combination of both urethras into a single functioning unit. The penis deviation was corrected after Ransley in the same operation. The postoperative course and aftercare showed normal micturition with a normotopic urethral entry as well as a good urine stream without evidence of a stricture or residual urine. An duplicate urethra is an uncommon malformation which is, however, found more often in male patients. Surgery is based on the individual and must be planned dependent on the morphology present. In all cases, both functional and cosmetic aspects must be taken into account.

RESUMEN

Endometriosis is a benign growth of ectopic endometrial mucous membrane which has maintained the histological characteristics and biological reactions of uterine mucous membrane. In only 1-2% of cases does it occur in the urinary system, most commonly in the urinary bladder. Such an endometriosis is often diagnosed very late due both to its commonly asymptomatic course and its rarity. Individual therapy is dependent on the age of the patient, the wish for children and the extent of the growth. For endometriosis covering a large area, surgery is recommended. Methods of choice are laparoscopic bladder resection for the urinary bladder, ureterocystoneostomy using the Psoas hitch for the distal ureter, end to end anastomosis or endoscopic incision for short, proximal cases, and for extended areas, ileum cross-bridge attachment or kidney mobilization using nephropexy.

RESUMEN

The impact factor, cited half-life, and immediacy index are three important methods that can be used to demonstrate how a journal's articles are cited over the course of a specific time span. These three factors thus represent instruments for measuring the importance and reputation of a scientific magazine. The goal of our study was to evaluate the constancy of journals specialized in the field of urology and to analyze those listed in the 2005 Journal Citation Report (JCR) using the standardized methods specified by the Institute of Scientific Information (ISI) and JCR. Primarily we wanted to examine the different time spans needed for publication of original papers submitted to certain journals; in more exact terms: the time span from submission of an article or original paper to its publication and from the time of acceptance of an original paper or article to its publication in a urological journal. Furthermore, we wanted to investigate the dynamics of urological journals regarding their impact factors for the years 2000-2005. The study was performed using the ISI JCR and the library as well as the online library of the Friedrich Alexander University in Erlangen. A very satisfactory development can be observed in the field of urology with the standardized methods of the (ISI) JCR.

RESUMEN

This article reports on a newborn with a scrotal space-occupying lesion and histologically proven granulosa cell tumor of the testes. A massive scrotal space-occupying lesion was diagnosed in a full-term male neonate with a birth weight of 2,260 g and body length of 45 cm. Sonography of the right testicle revealed a mass 6x6x4 cm in size which was multiply septate and cystic. The testicular parenchyma was poorly defined with a Swiss cheese appearance. Chemical analysis of blood serum evidenced normal levels of testosterone, beta-HCG, and inhibin B as well as physiologically a clearly elevated alpha-fetoprotein level at 35,350 ng/ml. Based on the clinical and sonographic findings of the right testicle, inguinal surgical exposure of the testes was undertaken. Since there was hardly any testicular parenchyma, we decided to perform high inguinal ablation of the right testicle. This case report confirms that congenital granulosa cell tumors usually exhibit benign behavior during the neonatal period.
