As many of you know when I recurred on my liver and spleen, I chose to have surgery followed by chemo. I made that decision after being offered three options. Option 1 surgery first then chemo ( carbo /taxol). Option 2 chemo first then surgery. And a clinical trial (GOG 213 ). I chose surgery first followed by chemotherapy.
The question about the benefits of a second surgery on recurrence has been ongoing. Last year at the SGO meeting there was a excellent discussion of the pros and cons given by Dr Gardner and Dr Coleman during the Education Forum. See this blog post .
Two of the trials that were discussed during the Forum included SOC-1 and GOG-213 .
SOC 1
The reported results showed a median progression-free survival (PFS) of 17.4 months in patients who had surgery and 11.9 months among those who did not have surgery. The trial has not yet reported Overall Survival (OS) numbers.
Conclusion: "Secondary cytoreduction followed by chemotherapy was associated with significantly longer progression-free survival than was chemotherapy alone in patients with platinum-sensitive relapsed ovarian cancer,..."
GOG 213
This study did not show any significant difference in PFS or OS in those who had secondary surgery and those who did not.
Conclusion:
"In this trial involving patients with platinum-sensitive, recurrent ovarian cancer, secondary surgical cytoreduction followed by chemotherapy did not result in longer overall survival than chemotherapy alone."

Earlier this month, the DESKTOP trial results was reported in the NEJM. https://www.nejm.org/doi/full/10.1056/NEJMoa2103294
This trial involved "first re- lapse after a platinum-free interval ... of 6 months or more to undergo secondary cytoreductive surgery and then receive platinum-based chemotherapy or to receive platinum- based chemotherapy alone. Patients were eligible if they presented with a positive Arbeitsgemeinschaft Gynäkologische Onkologie (AGO) score, defined as an Eastern Cooperative Oncology Group performance-status score of 0 (on a 5-point scale, with higher scores indicating greater disability), ascites of less than 500 ml, and complete resection at initial surgery."
In the study the median OS was 53.7 months for those who had surgery and 46.0
months in those that did not have surgery. Patients with a complete
resection (all visible disease removed) had a median overall survival
of 61.9 months.
Conclusion:
"In women with recurrent ovarian cancer, cytoreductive surgery followed by chemotherapy resulted in longer overall survival than chemotherapy alone. "
An editorial written by Drs Gardner and Chi ( also in the NEJM) regarding the DESKTOP trial and the SOC and GOG trials provides an excellent analysis of the differences in trial design, patient selection, quality of surgery and use of bevacizumab. https://www.nejm.org/doi/full/10.1056/NEJMe2116353
I may be biased, since my second surgery has kept me disease free for years, but I hope going forward secondary surgery, where appropriate, is included in all discussions between women with recurrent ovarian cancer and their gynecologic oncologists.
Thank you Drs Lars Henning (@mdlhenning) and Maria Kfoury (@kfoury) for the Twitter discussion on the DESKTOP results.
