Novak Djokovic and Rafael Nadal moved to within one win of a French Open quarter-final blockbuster Saturday as the sport's next generation endured a Grand Slam reality check. World number one and top seed Djokovic reached the last-16 for the sixth straight year with a 6-4, 6-4, 6-4 win over 19-year-old Australian Thanasi Kokkinakis. Defending champion Nadal, chasing a 10th title in Paris, brushed aside Russian world number 120 Andrey Kuznetsov, 6-1, 6-3, 6-2.
Worldwide, people who are diagnosed with melanoma are urged to have any lymph nodes that test positive for cancer removed, but researchers said Saturday the operation doesn't necessarily help patients live longer. Instead, many patients with advanced skin cancer that has just begun to spread to the lymph nodes nearest to the skin tumor could have the tumor removed but likely skip the additional surgery, known as complete lymph node dissection, according to the results of the randomized study released at the American Society of Clinical Oncology (ASCO) annual conference in Chicago. "I think that our study is the beginning of the end of a general recommendation of complete lymph node dissection for patients with positive sentinel nodes," said senior study author Claus Garbe, a professor of dermatology at the University of Tubingen in Tubingen, Germany.
