Multiple primary neoplasms in childhood: data from the German children’s cancer registry

1998

Abstract The German Children’s Cancer Registry (GCCR) has documented all malignancies during the first 15 years of life in Germany since 1980. In a series of 20 388 cancer cases to the end of 1995, 127 children with multiple primary neoplasms up to the age of 15 years were identified. The children were monitored for 82 591 person-years with a mean observation time of 4.1 years. Relative and cumulative risk for the occurrence of second malignant neoplasms were estimated only for the first 15 years of life, as follow-up data beyond childhood are incomplete and valid data on the incidence of cancer in adolescents and adults are not available in Germany. The overall standardised incidence ratio…

Health status of young children with cancer following discontinuation of therapy.

1987

This paper reports late effects and health status of 198 children who had cancer or leukemia diagnosed under 2 years of age and their therapies electively withdrawn. This series (92 neuroblastoma (NBL), 57 Wilms' tumor (WT), 46 acute lymphoblastic leukemia (ALL), and 3 non-Hodgkin's lymphoma) was followed for 1-12 years after discontinuation of therapy. Thirty-three children were diagnosed before 1973, 92 between 1973 and 1977, and 73 after 1977 in 16 Italian Pediatric Oncology Centers. As of December 1983, 176 children were reported to be alive and without evidence of primary cancer by physicians responsible for their care. One child died from a second primary tumor, two from late recurren…

Immunohistochemical Study as a Tool in Differential Diagnosis of Pediatric Malignant Rhabdoid Tumor

2010

Malignant rhabdoid tumors (MRTs) are aggressive childhood neoplasms, occurring mainly in the kidney and brain. We describe 2 unusual cases of extrarenal and noncranial location (liver and soft tissue with dissemination) mimicking hepatoblastoma, neuroblastoma or Ewing sarcoma. Both cases revealed a polyphenotypic profile, combined with cytokeratin, vimentin, and CD99 expression. INI1/BAF-47 showed negative protein nuclear expression in both cases, suggesting a diagnosis of MRT. An extensive immunohistochemical panel was performed to exclude pediatric tumors reminiscent of MRT. The genetic studies failed to detected MYCN amplification, 11q23 deletion, and EWS break-apart positivity. No alter…

Comprehensive Genomic and Transcriptomic Analysis of Three Synchronous Primary Tumours and a Recurrence from a Head and Neck Cancer Patient

2021

Synchronous primary malignancies occur in a small proportion of head and neck squamous cell carcinoma (HNSCC) patients. Here, we analysed three synchronous primaries and a recurrence from one patient by comparing the genomic and transcriptomic profiles among the tumour samples and determining the recurrence origin. We found remarkable levels of heterogeneity among the primary tumours, and through the patterns of shared mutations, we traced the origin of the recurrence. Interestingly, the patient carried germline variants that might have predisposed him to carcinogenesis, together with a history of alcohol and tobacco consumption. The mutational signature analysis confirmed the impact of alc…

Head and neck paragangliomas: Report of 175 patients (1989-2010)

2011

Attention of the otorhinolaryngologist needs to be drawn to the versatile aspects of head and neck paragangliomas (PGLs).This study is a retrospective, nonrandomized clinical study of all 175 individuals with PGLs treated in our department between 1989 and 2010. A genetic analysis was performed on 86 patients.The 175 patients presented 224 head and neck PGLs as well as 2 thyroid papillary carcinomas. Genetic analysis resulted in 1 patient positive for a von Hippel-Lindau (VHL) gene mutation and 34 for succinate dehydrogenase (SDH) gene mutations (22 SDHD, 7 SDHC, and 5 SDHB), 12 of the latter carrying a novel mutation. Thirty-three patients (18.9%) had multiple PGLs and 11 patients (6.3%) h…

Hybrid salivary gland tumor of the upper lip or just an adenoid cystic carcinoma? Case report

2010

A 65 year-old male patient with a one year-duration tumoral growth located in the upper lip was diagnosed on incisional biopsy as epithelial-myoepithelial carcinoma. After wide surgical excision the histopathological analysis revealed the lesion was composed predominantly (>90%) of adenoid cystic carcinoma. In new sections it was found a very small and isolated area of adenoid cystic carcinoma at the bottom of the incisional biopsy. As surgical margins were free of lesion, no adjuvant treatment was given. The occurrence of a transitory ischaemic attack at 36 months of follow-up led to a neurological and MRI evaluation, which disclosed a well-defined 3.5x3 cm lesion suggestive of metastasis,…

Epidemiology and prognosis of synchronous colorectal cancers

2008

Abstract Background The aim of this population-based study was to report on the incidence, treatment and prognosis of synchronous colorectal carcinomas. Methods Data were obtained from the population-based cancer registry of Burgundy. Results Between 1976 and 2004, 15 562 colorectal cancers were diagnosed. Some 3·8 per cent of patients had synchronous colorectal cancers. The risk of having synchronous cancers was higher in men (odds ratio (OR) 1·41 (95 per cent confidence interval (c.i.) 1·19 to 1·68)), when associated adenomas were present (OR 2·02 (95 per cent c.i. 1·69 to 2·41)), when there were adenomatous remnants on pathological examination (OR 2·10 (95 per cent c.i. 1·73 to 2·55)) an…

Coincident vesical transitional cell carcinoma and prostatic carcinoma. Clinical features and treatment.

1986

Summary— Twenty-two patients with vesical urothelial carcinoma associated with prostatic carcinoma were reviewed. They represented 1.5% of the bladder and prostatic tumours treated in our department within a 12-year period from 1968 to 1979. Their management included several treatment policies, based on the separate assessment of each tumour variant. For non-infiltrating bladder tumours, transurethral tumour resection was combined with hormonal treatment, external radiotherapy or resection of the prostate depending on the stage of the prostatic tumour. Radical cystoprostatectomy was performed for two cases of infiltrating bladder tumour with well localised prostatic tumours. A conservative …
