Prognostic and therapeutic implications of tumor-restrictive type III collagen in the breast cancer microenvironment.

Collagen plays a critical role in regulating breast cancer progression and therapeutic resistance. An improved understanding of both the features and drivers of tumor-permissive and -restrictive collagen matrices are critical to improve prognostication and develop more effective therapeutic strategies. In this study, using a combination of in vitro, in vivo and bioinformatic experiments, we show that type III collagen (Col3) plays a tumor-restrictive role in human breast cancer.

Splenogonadal fusion: a radiologic-pathologic correlation and review of the literature.

We present the case of a 29-year-old male who presented to his General Practitioner with a left testicular lump. Scrotal ultrasound examination revealed 4 well-defined, homogenous, mildly hypoechoic extratesticular mass lesions. He was referred for an urgent urological opinion and underwent local excision.

Post-menopausal presentation of yolk sac germ cell tumour.

•Yolk sac germ cell tumours are rare in post-menopausal patients.•Most involve mixed yolk sac tumours•Consider diagnosis in patients with a pelvic-abdominal mass and raised AFP.

Evaluation of a statistically derived decision tree for the cytodiagnosis of fine needle aspirates of the breast (FNAB).

A decision tree for the diagnosis of FNAB was derived from defined human observations using a rule induction method, C4.5 (a derivative of the ID3 algorithm). This algorithm is an implementation of the top-down induction method where the tree is determined iteratively by adding those nodes and branches which maximize the information gain at each step.
