Physiol Int

November 2024

2Centre of Radiotherapy, National Tumor Biology Laboratory, National Institute of Oncology, Budapest, Hungary.

Article Synopsis
  • Smoking and alcohol are major risk factors for oropharyngeal tumors, but there's a rise in HPV-related cases in younger patients; radiotherapy plays a crucial role in treatment.
  • A study of 95 patients treated with radio- or radio-chemotherapy showed that HPV positive tumors had better local control and survival rates compared to HPV negative tumors, with smoking adversely affecting outcomes.
  • The results suggest that treatment involving chemotherapy and radiation enhances survival for HPV-negative tumors more effectively, whereas the benefits are less pronounced for HPV positive tumors, highlighting the negative impact of smoking on response to treatment.

Article Synopsis
  • The rising incidence of colorectal cancer has emphasized the need for enhanced surgical training, particularly in Poland, where changes to the training program have increased the number of required intestinal procedures for residents.
  • A multicenter study (LILEO study) involving 199 patients aimed to evaluate ileostomy reversal safety, comparing outcomes between surgeries performed by specialist surgeons and those done by surgical residents.
  • Results showed that while the resident group had a shorter hospital stay and a lower overall complication rate, these differences weren't statistically significant; however, minor complications were more prevalent in the specialist group, indicating that resident-performed ileostomy reversals are safe and effective.

Article Synopsis
  • Succinate dehydrogenase-deficient renal cell carcinoma (SDH-deficient RCC) is a rare and aggressive subtype of kidney cancer mostly seen in younger patients, marked by mutations in SDHx genes, especially type B.
  • The tumors have unique histological characteristics, including eosinophilic cells in solid nests or microcysts that can trap normal kidney tubules.
  • In a study of three cases, all tumors showed a lack of SDHB expression and had pathogenic mutations, with two cases confirming the hereditary nature; diagnostic and treatment challenges arise due to overlapping features with other renal tumors.

Spectrum and genotyping strategies of "dark" genetic matter in germline susceptibility genes of tumor syndromes.

Crit Rev Oncol Hematol

January 2025

Department of Molecular Genetics, The National Tumor Biology Laboratory, National Institute of Oncology, Comprehensive Cancer Center, Ráth György út 7-9, Budapest H-1122, Hungary; Hereditary Tumours Research Group, Eötvös Loránd Research Network, Nagyvárad tér 4, Budapest H-1089, Hungary.

Article Synopsis
  • The study highlights that certain mutation types, particularly deep intronic variants, are often neglected despite advancements in genotyping methods, particularly in hereditary cancer syndromes.
  • A thorough literature review and analysis of variant databases were conducted to understand and evaluate methods for detecting these specific genetic variations.
  • The results indicate that most mutations are sporadic rather than inherited, but there's a strong chance that deep intronic variants have splice effects, demonstrating the need for effective genome sequencing and analytical approaches.

Glucocorticoid Receptor Isoforms in Breast Cancer Raise Implications for Personalised Supportive Therapies.

Int J Mol Sci

November 2024

Department of Molecular Genetics, The National Tumour Biology Laboratory, Comprehensive Cancer Centre, National Institute of Oncology, 1122 Budapest, Hungary.

Glucocorticoid receptor (GR) activation may promote metastasis in oestrogen receptor-negative and triple-negative breast cancer (TNBC). However, the role of the GRβ isoform, which has opposing effects to the main isoform, has not been studied in clinical samples. We aimed to analyse the intracellular localisation of total GR and GRβ in vitro using plasmid constructs and fluorescent immunocytochemistry.

Targeting hypoxia in combination with paclitaxel to enhance therapeutic efficacy in breast and ovarian cancer.

Biomed Pharmacother

November 2024

Department of Experimental Pharmacology and the National Tumor Biology Laboratory, National Institute of Oncology, Budapest, Hungary; Doctoral School of Semmelweis University, Budapest, Hungary.

The poor vascularization of solid tumors results in oxygen-deprived areas within the tumor mass. This phenomenon is defined as tumor hypoxia and is considered to be a major contributor to tumor progression in breast and ovarian cancers due to hypoxia-cascade-promoted increased metastasizing capacity. Hence, targeting hypoxia is a strategic cancer treatment approach, however, the hypoxia-modulating drugs face several limitations in monotherapies.

Immune checkpoint inhibitors (ICI)-based combinations have become the standard first-line treatment for advanced clear cell renal cell carcinoma (ccRCC). Despite significant improvements in survival and the achievement of sustained long-term responses, a subset of patients remains refractory to ICI, and most will eventually develop resistance. Thus, identifying predictive biomarkers for ICI efficacy and resistance is essential for optimizing therapeutic strategies.
