Hypothesis
Are clinical practice guidelines for chemotherapy in advanced stage gynecological malignancies consistent with available evidence?
Conclusion
Most professional societies provide guidelines that recommend chemotherapy even when its effectiveness is uncertain.
Supporting Evidence
- Only 31% of the societies provided any guidelines.
- Guidelines for breast and ovarian cancer used more randomized trials than those for cervical and endometrial cancer.
- All guidelines endorsed chemotherapy despite limited evidence for some cancers.
Takeaway
This study looked at guidelines for treating advanced cancers in women and found that many recommend chemotherapy, even when it's not clear if it helps.
Methodology
The study systematically reviewed guidelines from cancer and gynecological societies regarding chemotherapy for four types of advanced gynecological cancers.
Potential Biases
Potential conflicts of interest may exist as societies may benefit from recommending chemotherapy.
Limitations
Some entities did not have accessible websites, and the search may have missed some organizations.
Participant Demographics
Guidelines evaluated were from 224 professional societies and organizations worldwide.
