Her CA-125 level following adjuvant chemotherapy remains less than 5 for two years. She then develops bloating and ascites associated with carcinomatosis. What is your treatment recommendation at this time? 1. Retreat with a platinum-doublet 2. Non-platinum single agent 3. Delay treatment until bowel obstruction 4. Secondary debulking surgery Goals of Treatment Relapsed Ovarian Cancer • Prolong Survival • Delay Time to Progression • Control Disease-related Symptoms • Minimize Treatment-related Symptoms • Maintain or Improve Quality of Life Ovarian Cancer How is Relapse Defined? • Continuous rise in CA-125 • CA-125 above 100 • Radiographic recurrence • Symptomatic recurrence • Physical examination findings • Combination of above Issues Impacting Therapy for Recurrent Ovarian Cancer • Treatment-free interval – Impact of consolidation/maintenance therapy • Number of prior regimens – Response to prior therapy • Toxicity from prior therapy – Prior use of growth factors – Transfusion requirements – Neuropathy • Volume and site(s) of disease – Ascites/GI symptoms – Potential for secondary surgery – Performance status Effect of Platinum-Free Interval on Response Rate % Response to Second-line Platinum Therapy Platinum-Free Interval (mos) Markman 0-6 7-12 13-18 19-24 >24 27% Gore 17% 33% 27% 59% 57% Non-platinum Therapy Blackledge 29% 15% 20% 63% 30% 94% 30% 10% Markman M et al.

Her Ca125 level following adjuvant chemotherapy was <5. • She was followed every 3 months with examinations and Ca-125 levels, which were always <5. Case 1 Treatment Decisions • Six months ago her Ca-125 was slightly higher at 9. Three months later it was 21. Repeat physical examination at this time remains normal, imaging is normal, and this woman is asymptomatic. However, her Ca-125 is now up to 31. 1. What treatment plan would you recommend for Alice at this time? 2. What evidence would you cite as the basis for your plan? A PET/CT shows no measurable disease and 6 weeks later the CA125 is now 79. 3. How would your treatment change if she had three 4-6 cm masses.

Platinum-Sensitive Recurrence • Secondary surgical debulking can be considered for patients with late recurrence and low volume disease • Platinum retreatment is standard • Treatment with a platinum-based doublet improves response rate, progression-free survival, and possibly overall survival – Taxane Carboplatin: Paclitaxel, Docetaxel • Weekly paclitaxel ? – Gemcitabine Carboplatin +/- Bevacizumab – PLD Carboplatin • The role of targeted agents yet to be determined Platinum-Resistant Recurrent Ovarian Cancer Case 2: Platinum-Resistant Recurrent Ovarian Cancer • Kathy, a 60-year-old therapist, is referred by her gynecologist after a routine annual exam demonstrated a palpable adnexal mass. She has undergone TAH and BSO with findings of a stage IIIC high-grade serous adenocarcinoma with involvement of both ovaries, fallopian tubes, and the peritoneal cavity. • Debulking surgery was considered suboptimal with several residual nodules greater than 1 cm, and her Ca-125 several weeks post-op was mildly elevated at 30. • She completed 6 cycles of carboplatin-paclitaxel 5 months ago. At her most recent follow-up, she complained of anorexia and abdominal pain. CT scan reveals diffuse intraperitoneal disease. • Kathy has a medical history that includes diverticular disease treated with antibiotics 2 years ago, mild hypertension, and a DVT following an appendectomy 20 years ago Case 2 Questions 1. What chemotherapy plan would you recommend for Kathy at this time? 2. What evidence would you cite as the basis for your plan? 3.

Personalizing Therapy: Genetic Mutations and Resistance Markers • BRCA: Existing and emerging data on PARP inhibition and BRCA1/BRCA2 mutation show promise in the treatment of ovarian cancer • NCCN guidelines recommend germline testing for all patients with epithelial ovarian cancer, fallopian tube cancer and peritoneal cancer • Secondary mutations in 53CP1 or PTIP restrain DNA repair and may cause BRCA1/BRCA2 mutations to stop responding to PARP inhibitors • In the PRECEDENT trial, patients with platinum-resistant disease likely to benefit from the combination of vintafolide and PLD was enhanced by the FR-targeted imaging agent etarfolide (Naumann et al, J Clin Oncol, 2013). Quality Measures – ASCO Quality Oncology Practice Initiative (QOPI) • Complete staging for women with invasive stage I-IIIB ovarian, fallopian tube, or peritoneal cancer • Intraperitoneal chemotherapy offered and administered within 42 days of optimal cytoreduction to women with invasive stage III ovarian, fallopian tube, or peritoneal cancer • Platinum or taxane administered within 42 days following cytoreduction to women with invasive stage 1 (grade 3), IC-IV ovarian, fallopian tube, or peritoneal cancer • VTE prophylaxis administered within 23 hours of cytoreduction to women with invasive ovarian, fallopian tube, or peritoneal cancer (NQF endorsed #0218) • Order for prophylactic parenteral antibiotic administration within 1-2 hours before cytoreduction for women with invasive ovarian, fallopian tube, or peritoneal cancer (NQF endorsed #0527) • Order for prophylactic parenteral antibiotic discontinuation within 24 hours after cytoreduction for women with invasive ovarian, fallopian tube, or peritoneal cancer (NQF endorsed #0529) Patient Information Brochures from Ovarian Cancer National Alliance • A copy has been provided with your syllabus • Excellent tool to provide patients • Can be shipped to your office (minimal charge for postage) • Available online with additional resources at: – http://www.ovariancancer.org/ Participant CME Evaluation • Please take out the Participant CME Post-survey and Evaluation from the back of your packet • If you are not seeking credit, we ask that you fill out the information pertaining to your degree and specialty, as well as the few questions we will read through now measuring the knowledge and competence you have garnered from this program.

Patients under the age of 60 2. Patients with a significant family history 3. Patients diagnosed at early stage 4. All patients Post-activity Survey Question 5 Following optimal debulking surgery, a 60-year-old woman receives 6 cycles of carboplatin-paclitaxel.
