Narrative review evaluates chemotherapy cycles' effect on survival and surgical success in ovarian cancer, suggesting prolonged treatment may influence outcomes.
Although standard chemotherapy for three to four cycles followed by surgery is considered safe and effective in the management of advanced ovarian cancer, the impact of extending treatment beyond this period remains uncertain. Some authors suggest that the number of neoadjuvant chemotherapy cycles does not directly affect prognosis and may reflect a confounding bias. Others, however, indicate that a prolonged exposure to chemotherapy can promote the selection of resistant tumor clones, negatively influencing patient survival and disease progression. This review aims to summarize the current evidence on the topic, evaluating the effect of prolonged chemotherapy on surgical cytoreduction and survival. To achieve this, we conducted an analysis of the English-language literature available in PubMed, focusing on treatment duration, achievement of complete surgical resection, survival outcomes, and prognostic factors.
