RESUMEN

OBJECTIVE: The aim of the study was to describe trends in cervical cancer screening and outcomes for women under 25 years of age in Belgium between 2010 and 2019 in response to a changed reimbursement policy. MATERIALS AND METHODS: We used the databases of the National Health Insurance Institute (RIZIV/INAMI) and the Belgian Cancer Registry (BCR) for a nationwide description of cervical screening, subsequent diagnostic procedures and outcomes for women younger than 20 years and women aged 20-25 years between 2010 and 2019. RESULTS: Over a 10-year period, the number of cytology screening tests and annual screening rates in women younger than 25 years have been reduced by 50%, but no increases in invasive cervical cancer or high-grade intraepithelial lesion diagnoses were observed. The major determinant of this decreased overscreening has been the limitation of reimbursement in 2013 to once every 3 years instead of once every 2 years. In women aged 25-29 years, there is no increase in invasive cervical cancer diagnoses after decreased screening of women younger than 25 years. To detect 29 invasive cervical cancers in women younger than 25 during the 10-year study period, a total of 5606 conizations were performed and 43 million EUR of Belgian health insurance budget was spent. Since the cost of hospitalization, sickness leave and negative psychological impact were not included in our estimation, these costs are underestimated. CONCLUSION: Incidence of cervical cancer in women under 25 years remains low and screening is not effective in preventing cervical cancer, although there is clear evidence of potential reproductive harm and financial cost. We state that restricting reimbursement of cervical cancer screening before the age of 25 will improve guideline adherence and decrease healthcare expenditures without negatively impacting the health of the population.

RESUMEN

BACKGROUND: Sebaceous carcinoma is an aggressive malignant tumour. To prevent mutilating surgery and improve patient outcomes, early diagnosis and prompt treatment are necessary. When the tumour invades surrounding tissues, treatment may become complex. METHODS: We present a case report illustrating complex resection and reconstruction of a sebaceous carcinoma after initial misdiagnosis. RESULTS: A 74-year-old man with a sebaceous carcinoma to his right upper eyelid had a delay in treatment due to initial misdiagnosis. Upon the correct diagnosis, computed tomography scan showed tumour invasion of the medial rectus muscle and tumour spread to the right parotid gland. An orbital exenteration, partial parotidectomy and selective cervical lymphadenectomy were performed. Frozen section examination showed false-free margins, as additional paraffin embedded sections showed uncomplete tumour resection. Adjuvant radiotherapy was offered to the patient. The treatment was complicated by radio necrosis, necessitating surgical reconstruction by a paramedian forehead flap. Final reconstruction of the right orbit was accomplished by a personalised epithesis. CONCLUSIONS: Sebaceous carcinoma is a tumour that is often misdiagnosed. The aim of this case report is to emphasize the possible consequences of its misdiagnosis. An overview of characteristic clinical findings is provided to help reduce the number of misdiagnoses.

RESUMEN

A 35-year-old woman underwent bilateral lung transplantation for primary ciliary dyskinesia and developed vascular tumors over a slow time course. Initial presentation of non-specific vascular tumors in the lungs and liver for up to 6 years after transplantation evolved toward bilateral ovarian angiosarcoma. Tumor analysis by haplotyping and human leukocyte antigen typing showed mixed donor chimerism, proving donor origin of the tumoral lesions. In retrospect, the donor became brain dead following neurosurgical complications for a previously biopsy-proven cerebral hemangioma, which is believed to have been a precursor lesion of the vascular malignancy in the recipient. Donor-transmitted tumors should always be suspected in solid organ transplant recipients in case of uncommon disease course or histology, and proper tissue-based diagnosis using sensitive techniques should be pursued.

RESUMEN

Introduction. Lysosomal storage disorders (LSDs) are rare diseases with more than 50 different entities described today. The spectrum of phenotypes varies from severe to lethal and early-onset disease to mild and late onset. Recognition of the clinical signs and diagnostic workup is challenging and requires expertise. Diagnosis relies on finding abnormal metabolites in urine and serum followed by further enzymatic or molecular analysis. Routine histological examination of the foetal and placental tissues frequently shows vacuolisation, providing a readily available important clue to the diagnosis. Case Report. A third child of consanguineal parents showed several dysmorphic features and a complicated neonatal period with eventual demise in the early postneonatal period due to respiratory failure. An LSD was suspected based on clinical presentation, urine metabolite excretion, skeletal radiograph, and vacuolisation in lymphocytes and placental tissues on, respectively, blood smear and routine histological examination. Homozygosity mapping favoured galactosialidosis. The diagnosis was confirmed by massive parallel sequencing, revealing a single nucleotide variation in the CTSA gene (c.265A>C, p.Ser89Arg). Discussion. Histological placental examination may be either the first clue or complimentary evidence in recognizing LSDs. It is important to recognize these clues as it may prompt further investigation and facilitate earlier recognition of the disease.

RESUMEN

Stromal tumor-infiltrating lymphocytes (sTILs) are important prognostic and predictive biomarkers in triple-negative (TNBC) and HER2-positive breast cancer. Incorporating sTILs into clinical practice necessitates reproducible assessment. Previously developed standardized scoring guidelines have been widely embraced by the clinical and research communities. We evaluated sources of variability in sTIL assessment by pathologists in three previous sTIL ring studies. We identify common challenges and evaluate impact of discrepancies on outcome estimates in early TNBC using a newly-developed prognostic tool. Discordant sTIL assessment is driven by heterogeneity in lymphocyte distribution. Additional factors include: technical slide-related issues; scoring outside the tumor boundary; tumors with minimal assessable stroma; including lymphocytes associated with other structures; and including other inflammatory cells. Small variations in sTIL assessment modestly alter risk estimation in early TNBC but have the potential to affect treatment selection if cutpoints are employed. Scoring and averaging multiple areas, as well as use of reference images, improve consistency of sTIL evaluation. Moreover, to assist in avoiding the pitfalls identified in this analysis, we developed an educational resource available at www.tilsinbreastcancer.org/pitfalls.

RESUMEN

BACKGROUND: Pediatric germ cell tumors account for approximately 3.5 % of all childhood cancers for children under the age of 15 years. Up to one-third are extragonadal neoplasms. Germ cell tumors are a heterogeneous group of malignant tumors with a wide variety of histopathological features. Yolk sac tumor is the predominant variant in newborns and younger children. We report for the first time, the presentation of a primary yolk sac tumor in the abdominal wall of a small child. CASE PRESENTATION: An 18-month-old white girl underwent resection of a small, round subcutaneous lump (1.5×1.3×0.8 cm) of the abdominal wall in her right hypochondriac region. The histopathology was compatible with yolk sac tumor. Her alpha-fetoprotein was initially elevated but normalized after the resection. Magnetic resonance imaging of her abdomen was normal. The surgeon decided to observe and follow her alpha-fetoprotein level closely. One year after resection a local recurrence appeared and her alpha-fetoprotein rose to 58 ng/mL. The surgeon performed a wide resection of the lesion with normalization of her alpha-fetoprotein. Follow-up consisted of measuring alpha-fetoprotein, clinical evaluation, and abdominal ultrasound. CONCLUSIONS: Clinicians should be aware that a yolk sac tumor can present in an unusual extragonadal place, for example in this case it was subcutaneous. In some cases, conservative treatment can be carried out with careful monitoring of the patient and their alpha-fetoprotein.
