Introduction: Network pharmacology has emerged as a forefront and hotspot in anti-cancer. Traditional anti-cancer drugs are limited by the paradigm of "one cancer, one target, drug," making it difficult to address challenges recurrence drug resistance. However, main advantage network lies its approach from perspective molecular relationships, employing arrow, multiple targets" strategy, which provides novel pathway for developing drugs. This study employed bibliometric analysis method...
