The incidence of malignancy after renal transplant has been reported to range from 4% to 18%. Tumors of the skin and lip tend to be the most common with non-Hodgkin lymphoma comprising 20% of all neoplasms. Primitive neuroectodermal tumors (PNET) are collectively described as being a part of the Ewing sarcoma family of tumors. PNET occur more commonly in the second decade of life, predominantly affecting Whites and Hispanics, and rarely occur in individuals of African or Asian descent. The most common primary site of involvement is along the central axis, particularly the chest (Askin tumor), but it can arise in any soft tissue. PNET also occur in the head and neck. PNET involving the cervix, urinary bladder, uterus, and vagina have been reported. We describe a case of a 15-year-old female who, 9 years after receiving a living related renal transplant, developed a post-transplant PNET of the uterus.

In the last years increasing incidence of malignant diseases in young men is observed. Sperm cryopreservation before cancer therapy gives the opportunity for these men to have a child in the future, but it is not know whether pretreatment sperm quality is sufficient to preserve fertility potential after thawing. The aim of this study was to compare the semen parameters (volume, total count, concentration, motility, morphology) in young cancer patients before treatment with healthy men, and examining the differences in sperm quality among patients group. Semen specimens were obtained from 81 patients with different neoplasms (testicular cancer n = 65, others n = 16 (Hodgkin's disease n = 11, lymphoma n = 3, Ewing's sarcoma n = 1, osteosarcoma n = l1). Control group consisted of 43 healthy males at similar age that came to our division as potential sperm donors. The total sperm count, concentration per ml, motility (grade A, B and C) and morphology were significantly lower in the cancer patients compared with normal men (p < 0.05), but still adequate for the future assisted reproductive technologies. Patients with testicular neoplasms had only significantly lower total sperm count and concentration in comparison with other cancer patients (p < 0.05). Our results indicate that routine sperm banking should be offered for men before radio/chemotherapy to preserve future fertility.

Direct extension and hematogenous metastasis of primary non-CNS malignant tumors to the CNS are rare complications in children. The authors analyzed the incidence and outcome of these complications in Hungary. During a 14-year period between 1989 and 2002, 406 patients younger than 18 years were studied at Semmelweis University, Second Department of Pediatrics, in Budapest. Among the 406 patients with non-CNS solid tumors, nine hematogenous metastases and five direct tumor extensions to the CNS occurred. Primary tumors included rhabdomyosarcoma, neuroblastoma, tumors of the Ewing sarcoma family, non-Hodgkin lymphoma, and malignant chordoma. Mean interval between the initial diagnosis and the diagnosis of CNS involvement was 11.4 months. Despite intensive treatment, the mean survival after detection of CNS involvement was 10.4 months. The frequency of CNS involvement in non-CNS tumors is low, with a very poor survival.

Anterior mediastinal and adenoid masses in children after cessation of chemotherapy for malignant disease often cause a diagnostic problem. Differential diagnosis of thymic enlargement and adenoid hyperplasia from recurrence frequently poses a challenge both for the radiologist and the physician. In this study the authors evaluated 491 patients with different malignant tumors for thymic and adenoid hyperplasia. Thymic hyperplasia was seen in 18 patients (5 Hodgkin disease (HD), 5 non-Hodgkin lymphoma (NHL), 4 Wilms tumor, 2 germ cell tumor, 1 Ewing sarcoma, and 1 neuroblastoma), only adenotonsillar hyperplasia was seen in 6 patients, all with NHL, and both thymic and adenotonsillar hyperplasia were seen in 3 patients (1 HD, 2 NHL). In 5 patients, adenoid hyperplasia was proven by biopsy; 1 patient underwent to adenoidectomy. Their histopathologic investigation showed polyclonal follicular hyperplasia. The authors recommend that patients with thymic and/or adenotonsillar enlargement after successful treatment of their primary malignancy should be evaluated cautiously before an invasive procedure is planned.

The aim of this pilot study was to determine VEGF serum levels (S-VEGF) at diagnosis and at restaging in children diagnosed with cancer, and to investigate whether this parameter provides prognostic information for remission after induction therapy and response to treatment. S-VEGF levels of 35 consecutive pediatric patients with various types of cancer were assayed at diagnosis and at restaging. Levels of VEGF were determined using a commercially available ELISA anti-human VEGF immunoassay kit. Thirty-one children went into complete remission or had a very good partial response to first-line therapy; 4 patients developed tumor progression. At diagnosis average S-VEGF level was 495 pg/mL (range, 0.89--2220 pg/mL) and at restaging it decreased to 118.36 pg/mL (range, 7.44--487 pg/mL). (p=.0039). The 4 patients with tumor progression had increased S-VEGF levels at restaging. The comparison between the levels of S-VEGF at diagnosis and at restaging showed a significant difference for the patients who responded to treatment with decreased S-VEGF and the patients who developed tumor progression with increased S-VEGF (p=.0019). One child with metastatic Ewing sarcoma developed progressive disease after several weeks, with significantly progressively higher S-VEGF levels. One child with Hodgkin disease, who had a higher level at first restaging and developed progressive disease, responded to reinduction therapy and had a significantly lower level at the second restaging. The child with metastatic hepatoblastoma responded to first-line chemotherapy with concomitant decrease in S-VEGF and alpha-fetoprotein levels, but developed local recurrence with elevation in both parameters. Changes in S-VEGF levels correlated with response to treatment for most of the children diagnosed with cancer. This provides a rationale for exploring clinical interest in S-VEGF measurements of a larger group of children with malignancies, and using the test for clinical trials of antiangiogenic therapies.

Small round cell tumors (SRCTs) are a group of malignancies (non-Hodgkin lymphoma, neuroblastoma, retinoblastoma, hepatoblastoma, nephroblastoma, rhabdomyosarcoma, small cell anaplastic carcinoma, Ewing sarcomal peripheral neuroectodermal tumor, and desmoplastic small round cell tumor), characterized both cytologically and histologically by a predominantly small round to oval, and relatively undifferentiated cells. Together they form a formidable group and an overwhelming majority of childhood malignancies. The patients may present in later (inoperable) stage with huge intrathoracic and intraabdominal mass, when chemotherapy and/or radiation therapy may be the first or only line of treatment. As a less invasive procedure fine needle aspiration (FNA) cytology has definite advantage over surgical excision biopsy to arrive at a tissue diagnosis before initiation of therapy. Because of the morphologic similarities, the SRCTs may pose a differential diagnostic problem in the practice of clinical cytology, especially when they are poorly differentiated. Important cytomorphological features, which help in the identification of various SRCTs include completely dissociated cell population and lymphoglandular bodies (cytoplasmic fragments) in non-Hodgkin lymphoma (NHL), eosinophilicfibrillar material and Homer-Wright rosettes along with cellular processes in neuroblastoma, acinar formation in hepatoblastoma, blastema cells with tubular differentiation in nephroblastoma, tadpole shaped cells in embryonal rhabdomyosarcoma, extreme nuclear molding and perinuclear blue inclusion in small cell anaplastic carcinoma (SCAC), irregular, punched out and large cytoplasmic vacuolations due to glycogen in Ewing sarcoma, and sheets of undifferentiated small round cells surrounded by collageneous stroma in desmoplastic small round cell tumor (DSRCT). Some of these features such as nuclear molding, rosette, and acinar formation are noticed in more than one type of SRCTs. Moreover, the characteristic cytomorphological features may be present in 70-80% cases and for categorization of the remaining cases, contribution from ancillary studies is essential. It is suggested that cytomorphological features along with one or more of the parameters such as special stains (cytochemistry), immunocytochemistry (ICC), electron microscopy (EM), tissue culture, DNA ploidy, karyotype and molecular analysis can increase the diagnostic accuracy of SRCTs. However, these facilities may not be available in all the laboratories, especially in the developing countries, and even if available in a limited form, a tissue diagnosis has to be offered often by FNA cytology based on morphological features, as a life saving measure in seriously ill patients before the results of ancillary studies are finalized.

Whether in its preventive role of CNS prophylaxis for high-risk ALL, its central role in brain tumors, its adjunct role combined with chemotherapy for disease such as Hodgkin's lymphoma, Ewing's sarcoma, and rhabdomyosarcoma, or its palliative role for metastatic disease, radiation remains an important therapy for pediatric cancers.

To investigate the incidence and outcome of secondary neoplasms in pediatric patients treated for childhood cancer. Between December 1971 and January 2000, a total of 5859 patients younger than age 17 were diagnosed and treated for childhood cancers in our center. Of this group, 1511 (36%) patients were followed for more than 36 months. These long-term survivors were included in this analysis. Twenty-six patients developed a secondary malignancy with an overall risk of 1.7% in this cohort. The male:female ratio was 17:10, with a median age of 7.66 at diagnosis (range, 2 to 16 y). Four patients (14.8%) with Hodgkin lymphoma; 3 each (11.1%) with retinoblastoma and rhabdomyosarcoma; 2 each (7.4%) with Wilms tumor, Ewing sarcoma, medulloblastoma, ganglioneuroblastoma, and non-Hodgkin lymphoma; and 1 each (3.7%) with ependymoma, nasopharyngeal carcinoma, osteosarcoma, astrocytoma had a secondary malignant disease during the long-term follow-up period. Secondary malignant diseases were osteosarcoma in 6 patients, acute lymphoblastic leukemia in 2, acute myelogenous leukemia in 2, and rare malignant disease in others. Four patients with osteosarcoma developed disease within the radiation field. Osteosarcoma was the most frequently occurring secondary neoplasm. Less toxic treatment modalities should be used to decrease the risk of secondary malignant diseases.

Malignancies are rare young French adults but represent the third significant cause of death in the cohort of 15-24 years of age. The aim of this study was to investigate incidence and survival rates of French adolescents and young adults with cancer. All cases of cancer occuring over a 20-year period (1978-1997) in the cohort of patients aged 15 to 24, were obtained from nine population-based registries (10 % of the French population). Basal cell carcinomas of the skin were excluded. 1161 and 1884 cases were recorded in adolescents and young adults, respectively. Overall incidence rates (IR) were 161.4/10(6) in adolescents aged 15-19 years (M/F ratio = 1.3), and 252.6/10(6) in young adults aged 20-24 years (M/F ratio : 1.2). During the 1978-97 period, the IRs appeared stable over the years, +0.4 % [CI95 % = -2.3 ; +3.1] (p = 0.79) for adolescents and +1.7 % [CI95 % = -4.0 ; +7.3] (p = 0.57) for young adults. Five-year overall survival rates were 69.1 % [CI95 % = 66.4-71.8] for adolescents and 74.5 % [CI95 % = 72.3-76.7] for young adults. The 5-year survival rate for patients 15-24 years improved from 62.0 % (CI95 % = 57.5-66.5) in 1978-82 to 80.2 % (IC95 % = 77.7-82.8) in 1993-97. Noteworthy, results in adolescents and young adults are poor compared to the ones from their younger counterparts, especially in patients with acute lymphoblastic leukemia, non-Hodgkin lymphoma, Ewing's sarcoma, osteosarcoma, rhabdomyosarcoma, and astrocytoma. Further studies are warranted to elucidate whether these differences are due to intrinsic biological properties of the tumor or to differences in clinical practices in the two populations.

The objectives of our study were to quantify risks for developing new malignancies among childhood cancer survivors, identify links between particular types of first and subsequent cancer, and evaluate the possible role of treatment. A cohort of 25,965 2-month survivors of childhood cancer diagnosed in the U.S. during 1973-2002 was identified and followed through SEER cancer registries. Observed-to-expected ratios (O/E) were calculated, and Poisson regression was used to compare risks among treatment groups. Childhood cancer survivors were at nearly 6-fold risk of developing a new cancer relative to the general population (O/E = 5.9, 95% CI: 5.4-6.5). Most common were subsequent primary cancers of the female breast, central nervous system, bone, thyroid gland and soft tissue, as well as cutaneous melanoma and acute non-lymphocytic leukemia (ANLL). The greatest risks of subsequent cancers occurred among patients diagnosed previously with Hodgkin lymphoma (HL), Ewing sarcoma, primitive neuroectodermal tumor, or retinoblastoma. Risk of subsequent solid cancers was higher among persons whose initial treatment for childhood cancer included radiotherapy, whereas the excess of subsequent ANLL was strongly related to chemotherapy. The O/E for subsequent ANLL increased with increasing calendar year of initial cancer diagnosis among survivors of cancers other than HL, most likely due to increasing use of leukemogenic drugs for solid cancers and non-Hodgkin lymphoma. Childhood cancer survivors are at markedly increased risk of developing a variety of new cancers relative to the general population, but the magnitude of excess risk and specific types of second cancer vary widely by type of first cancer.
