Penn researchers discover genetic risk factor for testicular cancer

A study published in Nature Genetics found that men with two copies of the KITLG gene have a 4.5-fold higher risk of testicular cancer, while those with two copies of the SPRY4 gene have a 1.48-fold higher risk. The discovery sheds light on genetic factors contributing to the disease and may help identify critical environmental factors.

Liver disease 'shrunk' by blood-pressure drug

A clinical trial has shown that losartan, a blood-pressure medicine, can shrink liver scarring and allow the organ to repair itself in some patients with early-stage liver failure. The drug works by blocking a signalling pathway that causes scar tissue to accumulate, allowing the damaged area of the liver to be repaired.

New surgical technique shows promising results for patients with cervical cancer

A new surgical technique, total mesometrial resection (TMMR), has been shown to reduce complications and improve survival rates in patients with early-stage cervical cancer. The study found a 94% recurrence-free survival rate and a 96% 5-year survival rate, significantly better than traditional radical hysterectomy methods.
