The renal function of 74 children with malignant mesenchymal tumors in complete remission and who have received the same ifosfamide chemotherapy protocol (International Society of Pediatric Oncology Malignant Mesenchymal Tumor Study 84 [SIOP MMT 84]) were studied 1 year after the completion of treatment. Total cumulative doses were 36 or 60 g/m2 of ifosfamide (six or 10 cycles of ifosfamide, vincristine, and dactinomycin [IVA]). None of them had received cisplatin chemotherapy. Ages ranged from 4 months to 17 years; 58 patients were males and 42 females. The most common primary tumor site was the head and neck. Renal function was investigated by measuring plasma and urinary electrolytes, glucosuria, proteinuria, aminoaciduria, urinary pH, osmolarity, creatinine clearance, phosphate tubular reabsorption, beta 2 microglobulinuria, and lysozymuria. Fifty-eight patients (78%) had normal renal tests, whereas 16 patients (22%) had renal abnormalities. Two subsets of patients were identified from this latter group: the first included four patients (5% of the total population) who developed major toxicity resulting in Fanconi's syndrome (TDFS); and the second group included five patients with elevated beta 2 microglobulinuria and low phosphate reabsorption. The remaining seven patients had isolated beta 2 microglobulinuria. Severe toxicity was correlated with the higher cumulative dose of 60 g/m2 of ifosfamide, a younger age (less than 2 1/2 years old), and a predominance of vesicoprostatic tumor involvement. This low percentage (5%) of TDFS must be evaluated with respect to the efficacy of ifosfamide in the treatment of mesenchymal tumors in children.

The frequency of membranous lupus nephritis recurrence (World Health Organization (WHO) class V) in the allograft after renal transplantation is unknown, but it appears uncommon (only two reported cases in the literature). Despite the increased incidence of sarcomas in organ transplant recipients (compared to the general population), non-Kaposi's sarcoma is an uncommon malignancy, and primary tumor involvement of a renal allograft is a rare occurrence. Our patient is a 28 year old female with end-stage renal disease (ESRD) secondary to membranous lupus nephritis who received a living related transplant from her mother. At 26 months post-transplant, she presented with proteinuria and a rise in creatinine (Cr). Allograft biopsy was consistent with recurrent membranous nephropathy. Five weeks later, she was found to have a high-grade leiomyosarcoma originating within the allograft. We reviewed the literature on recurrent post-transplant membranous nephropathy and the possible role of the Epstein-Barr virus (EBV) infection in smooth muscle tumors occurring in organ transplant recipients. We also considered the association of membranous nephropathy and malignancy.

Angiogenesis and its role in the growth and development of metastases has become a topic of increasing importance. In non-small cell lung cancer (NSCLC), vascular endothelial growth factor (VEGF) plays an important role in angiogenesis, growth of the primary tumor, and development of metastases. In addition, elevated expression in tissue samples is a negative prognostic feature. For these reasons, VEGF is a worthy target for novel therapies. Recent clinical trials have shown that the anti-VEGF monoclonal antibody bevacizumab adds to the effect of chemotherapy in the metastatic setting. Hypertension and proteinuria are, as expected, commonly seen in this patient population, but the unexpected toxicity of life-threatening hemoptysis has also been observed. This makes careful patient selection especially important for this class of drugs. Our understanding of the VEGF pathway is increasing, as are the number of available targeted agents. In addition to the monoclonal antibody, bevacizumab, VEGF receptor tyrosine kinase inhibitors, multitargeted kinase inhibitors, and combination VEGF and epidermal growth factor receptor (EGFR) inhibition, are all being evaluated in NSCLC. Small phase I and II trials have suggested modest benefit when used alone; however, we now know that the anti-angiogenic therapies work best in combination with chemotherapy. The results of ongoing trials using these agents in combination with standard therapy will provide more insight into their potential benefit. As it is known that small tumors require angiogenesis to grow and metastasize, the use of anti-angiogenic therapies in the adjuvant setting may provide even greater benefit, and increase the potential cure rate in this population of patients. The results of well-designed phase III trials will be required to truly understand how to best use this class of targeted therapies in resectable and metastatic NSCLC.

Neuroblastoma is the most common extracranial solid tumor in childhood. Its presenting signs and symptoms may be highly variable, depending on the location of the primary tumor and its local or metastatic diffusion and, rarely, with paraneoplastic syndrome such as opsoclonus-myoclonus-ataxia syndrome and gastrointestinal disturbances, due to autoantibodies or to aberrant secretion of vasoactive intestinal peptide. Herein we describe a 10-month-old child with neuroblastoma presenting with a complex clinical picture characterized by acute kidney injury manifested by renal insufficiency and signs and symptoms of tubulointerstitial damage, with polyuria, polydipsia, glucosuria, aminoaciduria and hypochloremic metabolic alkalosis, and of glomerular damage with heavy proteinuria. Imaging study documented a suprarenal mass enveloping the aorta and its abdominal and renal ramifications and bilaterally renal veins. This clinical picture shows some analogies with the hyponatremic-hypertensive syndrome concerning the renovascular disease; however, in absence of systemic arterial hypertension, the heavy proteinuria and the polyuria could be explained by sectional increased intraglomerular pressure, due to local renal blood vessels constriction. Hypochloremic metabolic alkalosis probably developed because of local production of renin, responsible of renin-angiotensin-aldosterone system activation, but above all because of chloride loss through sweating. The long lasting dehydration, due to vomiting, sweating and polyuria, caused prolonged prerenal failure evolving in proximal tubular damage manifestations.

We report a case of multiple lung metastases of RAS mutant type descending colon cancer with development of nephrotic syndrome after the introduction of FOLFIRI plus ramucirumab(RAM). A female patient in her 50s underwent adjuvant chemotherapy with capecitabine and oxaliplatin after primary tumor and partial lung resection. For recurrent multiple lung metastases, 4 years of capecitabine and bevacizumab therapy was administered. FOLFIRI plus RAM therapy was introduced because of tumor progression. After treatment, the patient showed increased urine protein content, decreased serum albumin levels, marked hypertension, and increased edema, and was diagnosed with nephrotic syndrome. The patient's condition improved with prednisolone, additional doses of antihypertensive, and diuretics. Even in cases where it is possible to control proteinuria during bevacizumab administration, it is necessary to keep in mind that RAM administration as second-line therapy may cause nephrotic syndrome.
