Higher testosterone is associated with increased inflammatory markers in women with SARS-CoV-2 pneumonia: preliminary results from an observational study.

PURPOSE: Objective of this study was to assess the association between testosterone (T) levels and biochemical markers in a cohort of female patients admitted for SARS-CoV-2 infection in a respiratory intensive care unit (RICU). METHODS: A consecutive series of 17 women affected by SARSCoV-2 pneumonia and recovered in the RICU of the Hospital of Mantua were analyzed. Biochemical inflammatory markers as well as total testosterone (TT), calculated free T (cFT), sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) were determined. RESULTS: TT and cFT were significantly and positively associated with PCT, CRP, and fibrinogen as well as with a worse hospital course. We did not observe any significant association between TT and cFT with LH; conversely, both TT and cFT showed a positive correlation with cortisol. By LOWESS analysis, a linear relationship could be assumed for CRP and fibrinogen, while a threshold effect was apparent in the relationship between TT and procalcitonin, LDH and ferritin. When the TT threshold value of 1 nmol/L was used, significant associations between TT and PCT, LDH or ferritin were observed for values above this value. For LDH and ferritin, this was confirmed also in an age-adjusted model. Similar results were found for the association of cFT with the inflammatory markers with a threshold effect towards LDH and ferritin with increased LDH and ferritin levels for values above cFT 5 pmol/L. Cortisol is associated with serum inflammatory markers with similar trends observed for TT; conversely, the relationship between LH and inflammatory markers had different trends. CONCLUSION: Opposite to men, in women with SARS-CoV-2 pneumonia, higher TT and cFT are associated with a stronger inflammatory status, probably related to adrenal cortex hyperactivity.

High dose chemotherapy and autologous hematopoietic cell transplantation for Wilms tumor: a study of the European Society for Blood and Marrow Transplantation.

Survival for subgroups of patients with Wilms tumor (WT), such as those who suffer from relapse, is disappointing. Some patients' treatment plans include high-dose chemotherapy (HDT) with autologous hematopoietic cell transplantation (aHCT), although proof for its benefit is lacking. To increase the level of evidence regarding children with WT receiving aHCT as consolidation of first or second remission (after first relapse), we extracted relevant data from the European Blood and Marrow Transplantation Registry concerning 69 patients. Different HDT regimens were administered, mostly either melphalan-containing (n = 34) or thiotepa-containing (n = 14). For the whole population, 5-year overall survival (OS) and event-free survival (EFS) probabilities were 0.67 (±0.06) and 0.63 (±0.06), respectively (median observation time 7.8 years); for children transplanted in first remission, OS and EFS were 0.69 (±0.09) and 0.72 (±0.08). In univariate analysis, male gender and relapse in multiple sites were associated with lower OS probabilities. The use of a given pretransplant regimen (i.e. melphalan alone versus regimens with multiple drugs) did not seem to influence EFS/OS probability after aHCT, but significantly influenced platelet engraftment (more delayed with thiotepa). We here provide further data to improve the basis for future evidence-based clinical decision-making when using HDT and aHCT in relapsed/refractory WT.

Quality of life in long-term survivors treated for metastatic medulloblastoma with a hyperfractionated accelerated radiotherapy (HART) strategy.

PURPOSE: An intensive therapeutic strategy for metastatic medulloblastoma was launched in 1998 in our Institution. The aim of this study was to examine the long-term quality of life (QoL) in survivor patients at least 3 years after the end of the treatment. METHODS: Patients were asked to complete self-administered QoL questionnaires. An index of physical impairment (IPI) was scored (range 0-100; the lower the score the better) based on clinical objective observations. Patients were divided into two groups (lower IPI group, and higher IPI group) and descriptively compared accordingly. RESULTS: The study was completed by 25/33 eligible patients. Despite patients with a higher IPI reported worse perceived health condition, they had better emotional and psychological scores than those with a lower IPI in all QoL questionnaires. CONCLUSION: In our sample, patients with more severe objective and perceived physical impairments reported a better psychosocial QoL, possibly because the greater attention paid to them by society and family contributes to a better adjustment in long-term survivors. On this base, it should be recommended that all survivors receive a strong support as the most impaired patients.

Malignant ovarian germ cell tumors in pediatric patients: The AIEOP (Associazione Italiana Ematologia Oncologia Pediatrica) study.

OBJECTIVE: Malignant ovarian germ cell tumors (MOGCT) carry an excellent prognosis, and the treatment aims to achieve results with the least possible treatment-related morbidity. The aim of this study was to assess the outcomes of pediatric patients with MOGCT. METHODS: Patients were treated according to their stage: surgery and surveillance for stage I; a modified bleomycin-etoposide-cisplatin (BEP) regimen for stages II (three cycles), III, and IV (three cycles) with surgery on residual disease. RESULTS: Seventy-seven patients were enrolled (median age 11.8 years), 26 with dysgerminoma (Dysg), 13 with immature teratoma and elevated serum alpha-fetoprotein levels (IT + AFP), and 38 with nondysgeminoma (Non-Dysg) staged as follows: 27 stage I, 13 stage II, 32 stage III, 5 stage IV. Among evaluable patients in stage I (5-year event-free survival [EFS] 72.1% [95% CI: 56.4-92.1%]; 5-year overall survival [OS] 100%), seven relapsed (three patients with Dysg and four patients with Non-Dysg) and were rescued with chemotherapy (plus surgery in three patients). Among the evaluable patients with stages II-IV, 48 (98%) achieved complete remission after chemotherapy ± surgery, one (IT + AFP, stage IV) had progressive disease. In the whole series (median follow-up 80 months), the 5-year OS and EFS were 98.5% (95% CI: 95.6-100%) and 84.5% (95% CI: 76.5-93.5%). CONCLUSIONS: We confirm the excellent outcome for MOGCT. Robust data are lacking on surgical staging, surveillance for Non-Dysg with stage I, the management of IT + AFP, and the most appropriate BEP regimen. As pediatric oncologists, we support the role of surveillance after proper surgical staging providing cases are managed by experts at specialized pediatric centers.

[Differences in sports participation for children and adolescents with solitary kidney due to renal tumors across Europe. Time for harmonization]. / Partecipazione in attività sportive per bambini e adolescent con un solo rene. È tempo di armonizzare in comportamenti in Europa per I ragazzi guariti da un tumore renale.

As a result of advances in treatment, almost 90% of children diagnosed with Wilms tumor became long-term survivors, and have a sustainable quality of life. These patients' involvement in sports during their childhood is hopefully increasing too. The cornerstone of renal tumor cure remains radical nephrectomy, however, so survivors live with a solitary kidney. In most European countries and the USA, the involvement in sports of children with a solitary kidney depends on a responsible physician saying a "qualified yes", pending individual assessment. Unlike the case in the rest of Europe, in Italy having only one kidney automatically disqualifies an individual wishing to participate in any organized "competitive" sports carrying some risk of renal trauma, including basketball, soccer and sometime volleyball. This absolute restriction is based on ad hoc Ministerial rulings concerning "Health protection in sport activities". But available data do not seem to support such an absolute limitation on participation in sports based exclusively on the fact of having a single kidney. The sport-specific incidence of kidney injuries has been estimated at 2.3 injuries per million male athlete/exposures for basketball (2.5 for females), and 2.6 for soccer (6.0 for girls). Kidney injuries are significantly more rare than head or spine injuries. This article aims to provide Italian sport medicine specialists and policy-makers with the necessary background so that the current, over-protective "unquestionably no" response can be reconsidered, and converted into a still well-founded, more permissive attitude to the sports activities suitable for any children with a solitary normal kidney.

Treatment of relapsed Wilms tumour (WT) patients: experience with topotecan. A report from the SIOP Renal Tumour Study Group (RTSG).

BACKGROUND: Topotecan has been variably incorporated in the treatment of patients with relapsed Wilms tumour (WT) who failed initial treatment with three or more effective drugs. Our objective was to describe outcome and to retrospectively investigate the potential role of topotecan in relapsed WT patients. METHODS: Children who were treated with topotecan as part of their chemotherapeutic regimens for relapsed WT were identified and included in our retrospective study. Patient charts were reviewed for general patient characteristics, histology and stage at initial diagnosis, number and type of relapse, salvage treatment schedules, toxicity, response to treatment and outcome. RESULTS: From 2000 to 2012, 30 children (median age at relapse 5.5 years, range 1.6-14.5 years) were identified to have received topotecan as part of their salvage regimens (primary progressive disease n = 3, first, second and third relapse n = 13, 9 and 2 respectively, partial response n = 3). Topotecan was administered as a single agent (12 patients) or in combination with other drugs (18 patients). Sixteen patients had high-risk histology according to the SIOP classification, 15 died within 12 months because of progressive disease. Fourteen patients had SIOP intermediate-risk histology of which four patients displayed objective responses to topotecan. Overall, 6 out of 14 intermediate-risk patients survived (median follow up of 6 years), however, three of whom (stage V) had bilateral nephrectomy after topotecan treatment. CONCLUSIONS: Topotecan does not seem to show effectiveness in the treatment of relapsed WT patients with initial high-risk histology. In patients with intermediate-risk histology, the role of topotecan might deserve further attention, to prove its efficacy.

Treatment and outcome of patients with relapsed clear cell sarcoma of the kidney: a combined SIOP and AIEOP study.

BACKGROUND: Clear cell sarcoma of the kidney (CCSK) is an uncommon paediatric renal tumour. Relapses occur in about 15% of the patients. Since detailed clinical information on relapsed CCSK is scarce, the current study aims to describe outcome of patients with relapsed CCSK treated according to recent European protocols. PATIENTS AND METHODS: We analysed prospectively collected data of all CCSK patients who developed a relapse after complete remission at the end of primary treatment, entered onto SIOP and AIEOP trials between 1992 and 2012. RESULTS: Thirty-seven of 237 CCSK patients (16%) treated according to SIOP and AIEOP protocols developed a relapse. Median time from initial diagnosis to relapse was 17 months (range, 5.5 months - 6.6 years). Thirt-five out of thirty-seven relapses (95%) were metastatic; the most common sites of relapse were the brain (n=13), lungs (n=7) and bone (n=5). Relapse treatment consisted of chemotherapy (n=30), surgery (n=19) and/or radiotherapy (n=18), followed by high-dose chemotherapy and autologous bone marrow transplantation (ABMT) in 14 patients. Twenty-two out of thirty-seven patients (59%) achieved a second complete remission (CR); 15 of whom (68%) developed a second relapse. Five-year event-free survival (EFS) after relapse was 18% (95% CI: 4%-32%), and 5-year overall survival (OS) was 26% (95% CI: 10%-42%). CONCLUSIONS: In this largest series of relapsed CCSK patients ever described, overall outcome is poor. Most relapses are metastatic and brain relapses are more common than previously recognised. Intensive treatment aiming for local control, followed by high dose chemotherapy and ABMT, seems to be of benefit to enhance survival. Novel development of targeted therapy is urgently required.

Is there a role for FDG-PET for the assessment of treatment efficacy in Wilms' tumor? A case report and literature review.

BACKGROUND: The role of FDG-PET in Wilms' tumor has not been well established. The aim of this report is to describe the role of FDG-PET to assess chemotherapy efficacy and to show potential correlations between different Standardized Uptake Values (SUVs) and histopathological features in a patient with persisting metastatic disease. CASE DESCRIPTION: A 3-year-old boy was diagnosed with Wilms' tumor without anaplasia. The patient underwent treatment as according to the AIEOP-TW-2003 protocol, for stage III tumors. Therapy was discontinued with no evidence of disease, yet 9 months later thorax metastases were found. Although second and third line treatments were administered, conventional imaging demonstrated stable disease. Metronomic chemotherapy as well was employed for 44 months and FDG-PET was annually performed basing on responsible local physician choice trying to better describe the disease status. Four months after fourth line treatment was stopped, the patient manifested clinical symptoms; lesions began to increase their metabolic activity inhomogeneously. Therapy was hence restarted and SUVs decreased. Metastasectomies were then performed and histology revealed a correlation between viable disease shown by higher FDG-PET uptake and viable tumor areas. CONCLUSIONS: Our case discussion demonstrates that FDG-PET is potentially valuable in Wilms' tumor correlating SUV values and histological features of the tumor after chemotherapy. This case suggests that FDG-PET is a valid tool to assess chemotherapy response in relapsed Wilms' tumor even in case of no evidence of significant dimensional changes under conventional imaging.

Incidence and outcomes of patients with late recurrence of Wilms' tumor.

BACKGROUND: Most relapses from Wilms' tumor occur within 2 years from diagnosis. This study aims to describe the incidence and outcome of patients who experienced a late recurrence (LR) more than 5 years after diagnosis across several clinical trials, and to develop evidence-based recommendations for follow-up surveillance. METHODS: Available records on children with Wilms' tumor enrolled onto 10 national or international cooperative clinical trials were reviewed to identify patients who experienced a LR. RESULTS: Seventy of 13,330 (0.5%) patients with Wilms' tumor experienced a LR. No gender bias was observed. Median time elapsing between initial Wilms' tumor diagnosis and first recurrence was 13.2 years (range: 5.1-17.3 years). Initial tumor stage was: stage I (15); stage II (19); stage III (14); stage IV (8); bilateral disease stage V (14). The most frequent sites of relapse were--abdomen: 21, lungs: 20, and contralateral kidney: 15. Thirty-five children died of disease progression. Recurrence in the contralateral kidney was associated with a better outcome (13/15 patients alive), while initial tumor stage did not seem to influence the post-recurrence outcome. Therapies administered at recurrence varied between centers, preventing any conclusion about the best salvage treatment. CONCLUSIONS: LR of Wilms' tumor is rare and associated with similar outcome to those experiencing earlier recurrence. The low rate of LR does not justify prolonged monitoring. Further study of the biology of these tumors may give us some insights in regards to mechanisms on tumor cell dormancy or cancer stem cell maintenance.

"Postural Management" to prevent hip dislocation in children with cerebral palsy.

Muscolo-skeletal disorders and hip deformity play a key role on future development of motor and adaptive functions in children with cerebral palsy (CP). Lateral migration of the femoral head increases on average 7.7% per year and may progress in association with acetabular dysplasia to hip dislocation. Conservative preservation of muscle length and balance may prevent or reduce femoral head migration and acetabular dysplasia. Equipment for position lying, sitting, and standing is an established method of maintaining muscle length and joint range. French approach (Le Métayer et al) include the use of customised plaster cast orthoses, for sitting and standing positions, called siège moulé and gouttière, tailor-made according to the child's muscolo-skeletal characteristics and motor abilities. At our department, hips with clinical and radiological evidence of displacement unresponsive to pharmacological and surgical treatment were treated with postural management. The two cases we show in this paper underwent a physiotherapy programme (neurodevelopment treatment) twice a week and a seated postural programme 5 hours a day with the siège moulé. Hip radiographs were measured with the migration percentage (MP) described by Reimers. The follow-up measurements showed a progressive reduction of MP values of the hip treated, confirming the significant benefit from the combined non surgical approach. The study supports the evidence that conservative management of hip deformity with siège moulé can be successful if implemented before the development of hip dysplasia.

SCT for Wilms' tumour.

Thanks to advances in treatment, approximately 85-90% of patients suffering from Wilms' tumour are now cured. However, success rate after relapse is significantly lower, ranging from 25 to 45%. Several different re-induction approaches, more or less intensive according to first-line therapy and characteristics of relapse, have been proposed. A number of adverse prognostic factors related to a bad outcome after relapse have been identified and are used as inclusion criteria for entering in a programme including high-dose chemotherapy (HCT). HCT followed by autologous haematopoietic stem cell rescue has been used in small numbers of patients worldwide and promising results have been reported. Information from the European Group for Blood and Marrow Transplantation Database regarding more than 300 transplants have been gathered. In addition, literature data on rescue therapy and HCT will be discussed, such as recent treatment proposals currently under discussion within European and US cooperative groups.

Functional inactivation of the WTX gene is not a frequent event in Wilms' tumors.

For many years the precise genetic etiology of the majority of Wilms' tumors has remained unexplained. Recently, the WTX gene, mapped to chromosome Xq11.1, has been reported to be lost or mutated in approximately one-third of Wilms' tumors. Moreover, in female cases, the somatically inactivated alleles were found to invariantly derive from the active chromosome X. Consequently, WTX has been proposed as a 'one-hit' tumor suppressor gene. To provide further insights on the contribution of WTX to the development of the disease, we have examined 102 Wilms' tumors, obtained from 43 male and 57 female patients. Quantitative PCR analyses detected WTX deletions in 5 of 45 (11%) tumors from males, whereas loss of heterozygosity at WTX-linked microsatellites was observed in 9 tumors from 50 informative females (19%). However, in the latter group, using a combination of HUMARA assay and bisulfite-modified DNA sequencing, we found that the deletion affected the active chromosome X only in two cases (4%). Sequence analyses detected an inactivating somatic mutation of WTX in a single tumor, in which a strongly reduced expression of the mutant allele respect to the wild-type allele was observed, a finding not consistent with its localization on the active chromosome X. Overall, a functional somatic nullizygosity of the WTX gene was ascertained only in seven of the Wilms' tumors included in the study (approximately 7%). Our findings indicate that previously reported estimates on the proportion of Wilms' tumors due to WTX alterations should be reconsidered.

Transitory, spontaneously recovering, peripheral facial nerve palsy after vinorelbine administration.

Childhood intrinsic brain-stem gliomas have a dismal prognosis. Different treatment strategies have been adopted over the years without changing the final outcome of this ominous disease. Due to this grim prognosis, experimental therapeutic designs are worthwhile. Vinorelbine is a semi-synthetic vinca alkaloid that has demonstrated a broad spectrum of activity both in in vitro and in vivo experimental systems. By adopting vinorelbine during and after focal radiotherapy in the last two years, we have tried to evocate its known synergistic effect in brain-stem tumour control. Vinorelbine was administered intravenously before, during and after radiotherapy on tumour bed for a total duration of 10 months. All the consecutive patients whose clinical and radiological features corresponded to the diagnosis of an intrinsic brain-stem tumour, i.e., diffuse pontine glioma, have been accrued to this treatment protocol since July 2002. A histological assessment was not required. All patients were treated during hospital stay or in the outpatient clinic at the Istituto Nazionale Tumori of Milan (n=12) and at the Pediatric Clinic of Policlinico in Catania (n=1). Two of the thirteen patients so far treated have developed multiple subsequent, and transitory, episodes of monolateral peripheral facial nerve palsy during vinorelbine administration. The palsy always completely and spontaneously resolved at a short interval-around 30 min-after the end of the drug infusion. Obvious tumour progression was excluded by means of MRI; therefore the drug was administered as scheduled until the end of the treatment. We describe possible neurological and oncological implications of this unusual side effect, until now not reported in any other series dealing with vinorelbine as adjuvant treatment.

Spinal cord and vertebral stroke: a paediatric case.

Spinal cord ischaemia is a rare entity and very few cases of simultaneous spinal cord and vertebral body infarction have been reported: all of them in adult age. We observed a 15-year-old girl with abrupt onset of myelopathy and pain at the vertebral column studied by means of serial magnetic resonance imaging (MRI), and in whom bone infarction was a confirmatory sign of the vascular origin of the spinal lesion. This is to the best of our knowledge the first paediatric case described in the literature.

A case of relapsing glioblastoma multiforme responding to vinorelbine.

Childhood malignant gliomas are rare and their clinical behavior is almost as aggressive as in adults: they resist treatment, progress rapidly and often spread. Therapeutic strategies at relapse deserve an experimental approach, since none of the conventional-dose treatments have demonstrated a clear superiority over the others and no randomized trials have proved that high-dose chemotherapy is better than conventional treatment. Vinorelbine is a semi-synthetic vinca alkaloid with an in vitro and in vivo experimentally proven broad spectrum of activity, including against malignant brain glioma. We report our experience with a 19-year-old girl with glioblastoma multiforme (GBM) of the deep temporal region recurring 6 months after completing an intensive treatment that included preradiation chemotherapy (chemotherapy as a preradiation "sandwich" phase) with a myeloablative course of thiotepa, tumor bed radiotherapy and postradiation maintenance chemotherapy. The GBM proved fully responsive to intravenous vinorelbine, with a subsequent progression-free interval lasting more than 24 months. This case report suggests that vinorelbine is effective against high-grade pediatric glioma and, since this evidence has only one precedent in the literature (and given the generally poor prognosis for this tumor), even this single success seems worth reporting.

Stage 4 neuroblastoma: sequential hemi-body irradiation or high-dose chemotherapy plus autologous haemopoietic stem cell transplantation to consolidate primary treatment.

The aim of the present study was to evaluate the effectiveness of two consecutive nonrandomised treatment programs applied between 1989 and 1999 at the Istituto Nazionale Tumori of Milan in an unselected cohort of 59 children over the age of one with stage 4 neuroblastoma. Both treatment programs consisted of two phases, the induction of the remission phase and the consolidation phase. The induction of the remission phase consisted of intensive chemotherapy, and remained the same throughout the study period. The consolidation phase consisted of sequential hemi-body irradiation (HBI) (10 Gy per session, 6 weeks apart) in the first period (1988-June 1994) and sequential high-dose cyclophosphamide, etoposide, mitoxantrone+L-PAM and autologous haemopoietic stem cell transplantation in the second (July 1994-1999). Intention-to-treat analysis revealed a significantly better outcome for patients treated with the second program, the 5-year event-free survival probability being 0.12 for program 1 and 0.31 for program 2 (P=0.03). This finding led us to conclude that sequential HBI is useless as consolidation treatment. The high-dose chemotherapy adopted in the second program enabled a proportion of patients to obtain long-term survival but, since the clinical results remain unsatisfactory, new treatment strategies are warranted.

Case report: Pseudomonas aeruginosa-related intervertebral discitis in a young boy with medulloblastoma.

We report a case of a 15-year-old boy with desmoplastic medulloblastoma of the posterior fossa (T3M3, according to Chang classification) incompletely resected, with leptomeningeal and nodular spread in the posterior fossa and in the cervical and thoracic tracts of the spine, treated with sequential high dose iv chemotherapy and with hyperfractionated cranio-spinal radiotherapy. While on maintenance chemotherapy, the boy developed fever and septic status caused by Pseudomonas aeruginosa, and 1 week later also low back pain. Magnetic resonance imaging (MRI) demonstrated abnormal signal in the fourth ventricle and in the dorso-lumbar tract suggesting medulloblastoma recurrence, so he started with a chemotherapy program. Due to a worsening of back pain, a second MRI of the spine was performed that showed a spondilodiscitis of T11-T12 and L1-L2 discs. The histological and cultural examination of a fine-needle biopsy of the L1-L2 disc revealed the presence of P. aeruginosa. So patient was treated with intensive antibiotic therapy with resolution of the infection. Spondilodiscitis is a rare complication in neoplastic patients, maybe due to either immunodeficient status or invasive procedures such as lumbar puncture. This case demonstrates that MRI is a useful method for differentiating between infection and malignancy in the spine, but sometimes it may be difficult to distinguish metastatic tumor from a lesion due to spondilodiscitis. In this case surgicopathological assessment is crucial and mandatory.

Serum and cerebrospinal fluid human chorionic gonadotropin (hCG) and alpha-fetoprotein (AFP) in intracranial germ cell tumors.

We report a retrospective study on serum and cerebrospinal fluid (CSF) alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin (betahCG) determination in a series of 30 patients bearing intracranial germ cell tumors. At diagnosis five patients had high serum and CSF AFP levels. No patient had positive serum AFP and negative CSF AFP or vice versa. Twelve of 30 patients had serum betahCG levels above 5 mlU/mL, eight had high betahCG only in CSF, and ten were completely negative. During treatment and follow-up both markers were accurate indicators of the response to therapy, decreasing rapidly and often becoming normal already after the first phase of treatment. We conclude that these two markers, and mostly betahCG, may be useful in the diagnosis and monitoring of the response to therapy of patients with intracranial germ cell tumors.
