In this paper elaborate mathematical models and investigative computer simulations for the chemotherapy of haematological and gynaecological cancers are presented. The pharmacodynamics of the actions of the antineoplastic drugs are described by multicompartmental models with the associated model equations taking into account the drug dosage, type of delivery, route of delivery, the intercompartmental drug-transition constants, degradation parameters, and leakage coefficients. The cell-cycle phase-specific six-compartmental cytokinetic tumour growth model presented here incorporates the cell-cycle phase residence time, time lags associated with drug-induced cell-kill, or progression delays due to repair of cell damage. Investigative computer simulations are performed depicting the effects of cell-cycle phase-specific antineoplastic drugs on haematological and gynaecological cancer cells. The computer simulations are performed under various clinically plausible parametric configurations to elucidate the effects of certain critical variables such as tumour cell burden, mode of antineoplastic drug delivery, tumour cell loss and cell-cycle cytokinetic parameters.

Introduction: Glomerular diseases can be associated with solid or hematopoietic malignancies. The prevalence of these associations varies according to the studied glomerular disease. This study aimed to evaluate the frequency and type of neoplasms in patients with glomerular diseases as well as their clinical, laboratory, and histopathological features and the relationship with immunosuppressive therapy.

Objective: We evaluated the accuracy of oncologists' estimates of expected survival time in recurrent ovarian cancer.
Methods: Oncologists estimated expected survival time at baseline for each patient, who were then followed up for survival time. We hypothesized that oncologists' estimates of expected survival time would be independently significant predictors of survival, unbiased (approximately equal proportions [50%] living longer versus shorter than their expected survival time), or imprecise (<30% within 0.

Juvenile granulosa cell tumors (JGCTs), a rare type of ovarian tumor, are predominantly seen in premenarchal girls. We report a case of a 4.5-year-old girl with precocious puberty and a left ovarian JGCT, confirmed through imaging and histopathology.

Li-Fraumeni syndrome is a cancer predisposition syndrome caused by pathogenic TP53 germline variants and associated with a high lifelong cancer risk. We analysed the German LFS registry that contains data on 304 individuals. Cancer phenotypes were correlated with variants grouped according to their ability to transactivate target genes in a yeast assay using a traditional (non-functional, partially-functional) and a novel (clusters A, B, C) classification of variants into different groups.
