Abstract
Embryonal rhabdomyosarcoma (ERMS) is the most common subtype of RMS that predominantly involves the genitourinary tract and the head and neck regions in children younger than 10 years of age. Cytogenetically, ERMS is most frequently hyperdiploid, with extra copies of chromosomes 2, 7, 8, 11, 12, 13, and 20. No consistent structural chromosomal alteration has been identified in ERMS. In contrast, a t(2;13)(q35;q14) or t(1;13)(q36;q14) corresponding to PAX3-FOXO1A (previously FKHR) and PAX7-FOXO1A gene fusions are considered tumor-specific anomalies for alveolar RMS (ARMS). Occasionally, a recurrent secondary structural rearrangement involving chromosomes 1 and 16 is seen in translocation-positive ARMS, a der(16)t(1;16) resulting in an imbalance of 1q and 16q material. Conventional cytogenetic analysis of an ERMS arising in the urinary bladder of a 22-month-old male child revealed this nonrandom secondary chromosomal aberration, der(16)(1;16)(q22;q24), in a hyperdiploid complement with extra copies of chromosomes 2, 7, 8, 10, 12, 13, 19, and 20. Subsequent analyses showed tumor cells to be negative for FOXO1A, PAX3, or PAX7 gene locus rearrangements (by fluorescence in situ hybridization) and also negative for PAX3-FOXO1A and PAX7-FOXO1A fusion transcripts (by reverse transcriptase-polymerase chain reaction). These results suggest that the unbalanced t(1;16) translocation may be seen in RMSs lacking a primary genetic rearrangement.

Abstract
Both PRimed IN Situ (PRINS) and Peptide Nucleic Acid (PNA) technologies have emerged as research techniques, but they have quickly evolved to applications in biological diagnosis assays. The two procedures now constitute efficient alternatives to the conventional fluorescence in situ hybridization (FISH) procedure for in situ chromosome identification and aneuploidy detection. They present several advantages (specificity, speed, discriminating ability) that make them very attractive for a number of cytogenetic purposes. Multicolor PRINS and PNA protocols have been described for the specific identification of human chromosomes. Various applications have already been developed in human genetics and new adaptations are ongoing.

Abstract
The efficacy of fluorescence in situ hybridization (FISH) may be limited in specific applications by low-resolution sensitivity. Primed in situ labeling (PRINS) is based on specific hybridization of an unlabeled oligonucleotide with a denatured template and synthesis of a single-strand DNA in situ. This method may represent a powerful alternative to FISH for gene mapping because of its ability to generate multiple independent signals within the same gene segment. We investigated the specificity of signals produced by a modified PRINS protocol combining a centromeric probe for the X-chromosome with specific primers for 3'- and 5'-terminal regions of the dystrophin gene. In approximately 70% of nuclei from male and female subjects, we detected one or two large signals (X-chromosome centromere) and two or four smaller signals (the two regions of the dystrophin gene). Specific hybridization of the oligonucleotides on Xp was demonstrated by localization of the smaller (dystrophin) and larger (X-centromere) signals on the same chromosome. Simultaneous hybridization with a centromeric probe and gene-specific oligonucleotides allowed localization of PRINS signals, and assessment of the specificity of the primers used for hybridization. This approach could facilitate identification of female carriers of small intragenic deletions in the dystrophin gene.

Abstract
If a translocation is followed by loss of one of the two derivative chromosomes, the result is an unbalanced translocation, showing monosomy for the segments making up the lost derivative. We have found that in most unbalanced translocations, a third event takes place: a morphologically normal copy of one of the two translocation participants is added to the karyotype. This creates a complex abnormal karyotype with monosomy, disomy, and trisomy for different segments of the translocation participants. We have examined 82 unbalanced translocations from 77 patients, 73 of whom had a myeloid hemopoietic malignancy. Acquisition of a normal copy of a translocation participant was found in 49 translocations. Twenty-five of these showed trisomy for 1q. In 16 of the 25 1q-trisomic cases the translocation was t(1;7)(q10;p10) (trisomy for 1q and monosomy for 7q). Patients with trisomy for 1q were younger than the remaining patients. Whereas those with t(1;7))(q10;p10) showed brief survivals, those with trisomy 1q but monosomy for regions other than 7q survived longer than the remaining patients. We conclude that most unbalanced translocations involve a partial trisomy, that 1q is trisomic far more frequently than any other segment, and that partial trisomy is associated with patient age and survival.

Abstract
Recent cytogenetic and molecular genetic investigations in solid tumors in general, and in soft tissue tumors in particular, have provided us with a wealth of information. We have gained new insights in how tumors may arise, and some soft tissue tumors besides their identification by pathology now also have a genetic identity. This genetic identity is defined by: specific chromosome changes and by molecular changes related to the chromosome anomalies. However, much work remains to be done. In soft tissues as in other solid tumors many tumor types await the first or more extensive chromosome investigation, and in those in which nonrandom, especially simple chromosome changes emerge, molecular studies are to be undertaken starting from the breakpoints. Those tumors that seem to deviate chromosomally or molecularly from the expected, because of already established genetic changes, must be more thoroughly investigated by both pathologists and geneticists. The same accounts for the molecular investigation of chromosomally normal tumors known to show subtypes with specific chromosomal changes: e.g. lipoma, leiomyoma.

Abstract
Fluorescence in situ hybridization (FISH) using DNA probes of several hundred or thousand base pairs in length enables the visualization of chromosomal aberrations in interphase nuclei. A new method for in situ labelling of chromosomes is the oligonucleotide primed in situ labelling (PRINS) technique. So far, this has mainly been used to demonstrate subtle changes in metaphase spreads. The aim of the present study was to investigate the suitability of PRINS for detecting chromosome gains or losses in interphase nuclei. This technique was compared with FISH analysis by examining the bone marrow cells of ten patients in whom the karyotypes were known from conventional chromosome banding. Corresponding results by both PRINS and FISH were obtained for chromosomes 1, 3, 7, 8, and Y in five patients with normal chromosome patterns, as well as in five patients with clonal karyotype changes, e.g., monosomy 7, trisomy 8, or loss of the Y chromosome. Being faster and approximately ten times less expensive, PRINS can replace FISH for detecting numerical karyotype changes.

Abstract
The cytogenetic hallmark of the Ewing family of tumors is t(11,22)(q24;q12) in its simple, complex or variant forms and/or its molecular equivalent EWS/FLI, EWS/ERG rearrangement. Additional secondary consistent chromosomal aberrations include the der(16)t(1;16) and frequently, other chromosome 1q abnormalities leading to 1q overdosage. We studied whether these secondary cytogenetic changes are correlated to clinical features and phenotypic expression which may have a prognostic impact. Successful cytogenetic evaluation was performed in eight patients with a Ewing family tumor. In four of these, in addition to the primary aberration, chromosome 1q overdosage (including two with der (16)t(1;16)) was noted. Out of these four patients, two had metastatic disease at the time of evaluation, while in the other four, disease was localized. Morphologically, the tumors with the additional 1q aberration, revealed the pPNET subtype more frequently than the typical Ewing. They also expressed a higher degree of neural differentiation by neural marker immunocytochemistry, in comparison to tumors without the 1q aberration. Determination of the prognostic significance of this finding requires a longer follow-up with a larger group of patients.

Abstract
The der(16)t(1;16) has been detected cytogenetically in a number of malignancies including Ewing tumors (ETs). To enable fast and reliable analysis of der(16) chromosomes, we established an interphase cytogenetic approach. By using two DNA probes hybridizing to the heterochromatic portions on the long arms of chromosomes 1 and 16, this technique allows the detection of this chromosomal aberration in nonproliferating cells. Formation of the der(16) leads to partial excess of 1q material and partial loss of the long arm of chromosome 16. Double-target fluorescence in situ hybridization (FISH) experiments were performed on cytospin slides of 13 ETs, near-triploid tumor cells and normal cells to assess whether the FISH technique used permits the discrimination of nuclei harboring this aberration from nuclei without a der(16) chromosome. In five ETs, we found evidence for the presence of one or two der(16)t(1;16) chromosomes both by FISH and by conventional cytogenetics. Tumor cells displayed two signals for intact chromosomes 1, one or two additional fused signals for the der(16) chromosomes, and one signal for the intact chromosome 16. In one case without fused signals, the presence of a der(16) was demonstrated by hybridizing a painting probe for chromosome 16 simultaneously with the paracentromeric probe for chromosome 1. Our results suggest that double-target FISH on interphase nuclei offers an ideal tool for analyzing tumors prospectively and retrospectively to assess the biological role and the possible prognostic impact of the der(16) in ETs and in other solid tumors.

Abstract
Alveolar rhabdomyosarcoma is an aggressive childhood tumor that exhibits muscle cell differentiation. Cytogenetically, it is characterized by t(2;13)(q35;q14); no consistent secondary abnormalities have been reported. Cytogenetic analysis of bone marrow in a case of alveolar rhabdomyosarcoma revealed t(2;13)(q35;q14) and der(16)t(1;16)(q21;q13). The present case and a review of the literature suggest that up to 11% of these tumors possess der(16)t(1;16)(q21;q13). This is similar to the incidence observed in the Ewing family of tumors, where unbalanced der(16)t(1;16) translocations, resulting in partial trisomy of 1q, are regarded as a consistent secondary cytogenetic change.
