Seventy four consecutive patients with epithelial ovarian cancer have been followed up longitudinally with serial serum CA125 for up to 48 months. From this database, the CAl25 changes in small volume disease have been evaluated. For long term complete responders (n = l2), the mean plateau level of CA125 was 7.2 U/ml (95% confidence interval; 5.6 to 9.2 U/ml). The natural half-life of CA125 at 5.1 days (range 3.8 to 7 days) was calculated from five patients with Stage I and II disease who underwent complete surgical excision. A mean lead time of 99 days (range 14 to 255 days) was demonstrated between marker detection of disease progression and clinically apparent progressive disease in 12 out of 13 patients (92%) who relapsed after chemotherapy induced complete remission. The threshold of tumour volume detection with CA125 is unlikely to be determined by an arbitrary cut-off level. The kinetics of CA125 provide more useful information and the potential to define complete response or indeed cure with CA125 parameters requires further investigation.

Fifty-six patients with ovarian cancer (three stage IC, nine stage II, 33 stage III and II stage IV) were treated with carboplatin 350 mg m−2 i.v. day 1 and chlorambucil orally 0.15 mg kgm−1 days 1–7 inclusive, repeated every 28 days for eight courses. The regimen was well tolerated and was virtually free of nephro- and neurotoxicity. Grade III or IV hematology toxicity occurred in 18 patients but only 31 or 330 courses administered were delayed. Of 40 assessable patients eight achieved a clinical/radiologic complete response and 17 a clinical/radiologic partial response. Actuarial survival at 50 months was 65% for stage II patients, 27% for stage III patients and no stage IV patients survived beyond 20 months. Forty-two per cent of patients with residual disease less 2 cm survived 50 months, compared with 44% of patients with moderate volume (2–5 cm) residual disease and 6% of patients with bulk residual disease. This is an active, well tolerated regimen. However, only patients with small volume residual disease have a significant chance of prolonged survival.

ObjectiveTo investigate the efficacy and safety of hu3S193, a humanized anti-Lewis-Y monoclonal antibody, as a consolidation strategy in patients with platinum-sensitive recurrent epithelial ovarian cancer who achieved a second complete response after salvage platinum-doublet chemotherapy.MethodsThis single-arm phase II study accrued patients with recurrent epithelial ovarian cancer with Lewis-Y expression by immunohistochemistry who had achieved a second complete response after five to eight cycles of platinum-based chemotherapy. Patients received intravenous infusions of hu3S193, 30 mg/m2 every 2 weeks starting no more than 8 weeks after the last dose of chemotherapy and continuing for 12 doses, until disease progression, or unacceptable toxicity. The primary endpoint was progression-free survival of the second remission. Secondary objectives were safety and pharmacokinetics.ResultsTwenty-nine patients were enrolled. Most had a papillary/serous histology tumor (94%), stage III disease at diagnosis (75%), and five (17%) underwent secondary cytoreduction before salvage chemotherapy. Two patients were not eligible for efficacy but were considered for toxicity analysis. Eighteen patients (62%) completed the full consolidation treatment while nine patients progressed on treatment. At the time of analysis, 23 patients (85%) of the eligible population had progressed and seven of these patients (26%) had died. Median progression-free survival of the second remission was 12.1 months (95% CI: 10.6–13.9), with a 1-year progression-free survival of the second remission rate of 50.1%. The trial was terminated early since it was unlikely that the primary objective would be achieved. The most commonly reported treatment-related adverse events were nausea (55%) and vomiting (51%).ConclusionsHu3S193 did not show sufficient clinical activity as consolidation therapy in patients with recurrent epithelial ovarian cancer who achieved a second complete response after platinum-based chemotherapy.Trial registrationNCT01137071.

e18046 Background: Although advances in chemotherapy, cytoreductive surgery, and maintenance therapy (SOC) improved PFS for high grade epithelial ovarian cancer, > 20% of patients relapse during the first 6 months and 60% relapse after 6 months. Submicron particles (~800 nm) of paclitaxel (SPP) contain 1-2 billion molecules of pure drug that release tumoricidal levels of paclitaxel over many weeks. In a previous trial, percutaneous instillations of SPP in nonsurgical patients with intraperitoneal cancer were associated with reduced systemic and local toxicity as compared to standard chemotherapy regimens. (Williamson et al Cancer Chemo Pharm (2015) 75:1075). Methods: This study compared two dose-levels of IP SPP instilled in 200 ml of saline post-cytoreductive surgery. Eligible patients with primary (n = 6) or recurrent (n = 4) epithelial ovarian cancer who underwent complete cytoreductive surgery were enrolled to receive a single instillation of IP SPP followed by standard IV carboplatin and paclitaxel. Endpoints were PFS and evaluation of treatment-emergent adverse events. Clinical response was determined by CT scans and serum CA-125 measurements. Results: Of the 24 subjects screened, 10 were enrolled and received treatment: seven patients received 100 mg/m2 and three received 200 mg/m2. For analysis purposes, 7 out of 10 subjects were evaluable (1 withdrew, 1 died unrelated to study drug during IV treatment and 1 was unevaluable). Upon completion of planned chemotherapy post-SPP instillation, the PFS at 6 months was 66% (4/6) and at 12-months 66% (4/6) using RECIST 1.1. One subject had a complete response at the end of IV treatment, but died (unrelated to study treatment) before PFS evaluation. There was one case of incision dehiscence and one case of vaginal cuff leakage after surgery. Conclusions: This pilot study supports further evaluation of IP SPP to treat peritoneal carcinomas. Clinical trial information: NCT03029585.

ObjectiveThe objective of this retrospective study was to assess the clinical outcome of patients with advanced epithelial ovarian cancer in complete response after primary debulking surgery (PDS) or neoadjuvant chemotherapy followed by interval debulking surgery (IDS]).MethodsThe authors reviewed the hospital records of 384 patients who underwent PDS (n = 322) or IDS (n = 62) and who were in complete response after primary treatment.ResultsOptimal (residual disease [RD] < 1 cm) and complete (no gross RD) cytoreduction rates were higher after IDS than after PDS (71.0% vs 55.9%;P= 0.001 and 51.6% vs 35.7%, respectively;P= 0.02). Tumor recurred in 73.0% of the 322 complete responders after PDS versus 87.1% of the 62 complete responders after IDS (P= 0.01). The IDS group showed a higher recurrence rate within 6 months (11.3% vs 3.1%:P= 0.01) and a trend to higher recurrence rate between 6 and 12 months (30.6% vs 19.9%). Tumor recurred in 57.4% of the 115 completely cytoreduced patients after PDS versus 87.5% of the 32 completely cytoreduced patients after IDS (P= 0.001). The IDS group showed a trend to higher recurrence rate within 6 months (6.2% vs 1.7%) and a higher recurrence rate between 6 and 12 months (37.5% vs 15.6%;P= 0.01). Two-year, 5-year, and 7-year progression-free survival were 65.8%, 40.8%, and 39.3% for completely cytoreduced patients after PDS versus 43.8%, 12.5%, and 12.5% for completely cytoreduced patients after IDS (P= 0.001); and 2-year, 5-year, and 7-year overall survival were 96.4%, 69.3%, and 50.4% for the former versus 87.1%, 41.8%, and 32.6% for the latter (P= 0.001).ConclusionsThe clinical outcome of completely cytoreduced patients was significantly better for PDS group than for IDS group, and therefore, the achievement of no gross RD after surgery seemed to have a different prognostic relevance for the 2 groups.

Background. Surgical excision of ovarian endometriomas in patients desiring pregnancy has recently been criticized because of the risk of damage to healthy ovarian tissue and consequent reduction of ovarian reserve. A correct diagnosis in cases not scheduled for surgery is therefore mandatory in order to avoid unexpected ovarian cancer misdiagnosis. Endometriosis is often associated with high levels of CA125. This marker is therefore not useful for discriminating ovarian endometrioma from ovarian malignancy. The aim of this study was to establish if the serum marker CA72-4 could be helpful in the differential diagnosis between ovarian endometriosis and epithelial ovarian cancer.Methods. Serums CA125 and CA72-4 were measured in 72 patients with ovarian endometriomas and 55 patients with ovarian cancer.Results. High CA125 concentrations were observed in patients with ovarian endometriosis and in those with ovarian cancer. A marked difference in CA72-4 values was observed between women with ovarian cancer (71.0%) and patients with endometriosis (13.8%) ().Conclusions. This study suggests that CA72-4 determination can be useful to confirm the benign nature of ovarian endometriomas in women with high CA125 levels.

PURPOSE This study aimed to evaluate the activity and toxicity of carboplatin (PPL) and ifosfamide (IFO) in patients with epithelial ovarian cancer previously treated with cisplatin (CDDP)-containing regimens. PATIENTS AND METHODS From July 1989 to December 1991, 35 patients with epithelial ovarian cancer relapsed or refractory to CDDP as first-line chemotherapy were treated. PPL was administered at a dose of 300 mg/m2 intravenously (IV) on day 1 and IFO at a dose of 1,500 mg/m2 IV on days 1 to 3 every 3 to 4 weeks. Criteria for evaluating previous response to CDDP were strictly defined. RESULTS The overall response rate was 43% (complete response [CR], 6%; partial response [PR], 37%) and the median duration of response was 7 months (range, 3 to 16). In potentially platinum-sensitive (PPS; relapsed) patients, the overall response rate was 56%. None of the primary platinum-resistant (PPR) patients obtained a clinical response to PPL plus IFO, whereas one of five secondary platinum-resistant (SPR) patients obtained a PR. The regimen was easily manageable. CONCLUSION PPL plus IFO is useful and well-tolerated combination in salvage treatment of patients with advanced ovarian cancer. However, clear synergism between PPL and IFO that could overcome intrinsic or acquired CDDP resistance was not observed. The advantage of PPL plus IFO as compared with CDDP-containing regimens is represented by the increased tolerability and the reduced neurotoxicity, nephrotoxicity, and ototoxicity as compared with CDDP-containing regimens. It is essential that the patient population be defined according to their previous response to platinum therapy in trials involving second-line therapy of ovarian cancer.
