Platinum Based Chemotherapy

Purpose To assess whether the interval from primary surgery to the start of taxane- plus platinum-based chemotherapy has any impact on the clinical outcome of advanced ovarian cancer patients. Patients and Methods The study was conducted on 313 patients who underwent surgery followed by taxane- plus platinum-based chemotherapy. The median follow-up of survivors was 30.7 months (range, 6 to 109 months). Results The 25%, 50%, and 75% quantiles of intervals from surgery to the start of chemotherapy were 11, 21, and 31 days, respectively. After the sixth cycle, 102 patients achieved a pathologic complete response at second-look surgery and 98 obtained a clinical complete response but were not submitted to second-look surgery. Taking into consideration the best assessed response, a complete (either clinical or pathologic) response was found in 200 patients. Residual disease (≤ 1 v > 1 cm; P < .0001) and ascites (absent v present; P = .003) were independent predictive factors for achieving a complete response, whereas residual disease (P = .001) and stage (IIc to III v IV; P = .04) were independent prognostic variables for survival. Conversely, statistical analyses failed to detect significant differences in complete response rates and survival among patients with an interval from surgery to chemotherapy shorter than 11 days, 12 to 21 days, 22 to 31 days, and longer than 31 days. Conclusion The interval from surgery to the start of taxane- plus platinum-based chemotherapy seems to have neither a predictive value for response to treatment nor a prognostic relevance for survival of advanced ovarian cancer patients.

Second Look

After primary surgery, 125 patients with epithelial ovarian cancer (International Federation of Gynaecology and Obstetrics [FIGO] 1c + IIb + IIc = 22 patients, FIGO III = 82 patients, FIGO IV = 21 patients) were randomly allocated to receive PC (cisplatin 50 mg/m2 + cyclophosphamide 600 mg/m2 on day 1 every 28 days) (corrected) or PAC (PC + doxorubicin 45 mg/m2). After six cycles, patients clinically disease-free or with resectable residual disease were submitted to second-look surgery. After restaging, patients in surgical complete response (CR) stopped treatment while those responding partially (PR) received six more courses; patients whose disease progressed were excluded from the study. Among patients with measurable disease, the following clinical response rates were observed: PC = 20% CR, 34.3% PR, 14.3% stable disease, and 31.4% progression; PAC = 40.6% CR, 15.6% PR, 12.5% stable disease, and 31.3% progression. In the 75 patients submitted to second look, the results have been the following: PC = 39.5% CR, 36.8% PR, 7.9% stable disease, and 15.8% progression; PAC = 62.2% CR, 18.9% PR, 10.8% stable disease, and 8.1% progression. The difference in surgical complete response in favor of the PAC regimen is significant (P less than .05). Median survival and progression-free survival were 800 and 400 days, respectively, for PAC arm; median survival and progression-free survival were 680 and 380 days, respectively, for PC. These differences are not significant. Probability of survival was affected by FIGO stage, amount of residual disease, histology, performance status, and response at second look, while no influence was observed according to grade of tumor differentiation and age. Our results demonstrate the usefulness of doxorubicin in terms of surgical CR.

Tumor Debulking

Primary surgery for advanced ovarian cancer has been the standard practice for more than 30 years. A survival benefit is principally seen in patients who have optimal cytoreduction with no or small-volume residual disease after surgery. In everyday clinical practice, many patients are not able to undergo optimal tumor debulking. Modern preoperative imaging and assessment can identify most of these patients. Through developments in platinum-based chemotherapy, a high proportion of patients can be expected to respond to primary (neoadjuvant) chemotherapy. A recent clinical trial has shown that the survival of patients with operable disease is not disadvantaged by neoadjuvant chemotherapy followed by surgery. Thus, complete tumor cytoreduction could be achieved in a greater percentage of patients, if primary chemotherapy is used in women in whom optimal primary surgery would be difficult. Furthermore, delayed surgery provides more knowledge about the biological behavior of the tumor, and this could be used to tailor treatment more effectively.

Generation Sequencing

Next-generation sequencing (NGS) technology has advanced knowledge of the genomic landscape of ovarian cancer, leading to an innovative molecular classification of the disease. However, patient survival and response to platinum-based treatments are still not predictable based on the tumor genetic profile. This retrospective study characterized the repertoire of somatic mutations in advanced ovarian cancer to identify tumor genetic markers predictive of platinum chemo-resistance and prognosis. Using targeted NGS, 79 primary advanced (III–IV stage, tumor grade G2-3) ovarian cancer tumors, including 64 high-grade serous ovarian cancers (HGSOCs), were screened with a 26 cancer-genes panel. Patients, enrolled between 1995 and 2011, underwent primary debulking surgery (PDS) with optimal residual disease (RD < 1 cm) and platinum-based chemotherapy as first-line treatment. We found a heterogeneous mutational landscape in some uncommon ovarian histotypes and in HGSOC tumor samples with relevance in predicting platinum sensitivity. In particular, we identified a poor prognostic signature in patients with HGSOC harboring concurrent mutations in two driver actionable genes of the panel. The tumor heterogeneity described, sheds light on the translational potential of targeted NGS approach for the identification of subgroups of patients with distinct therapeutic vulnerabilities, that are modulated by the specific mutational profile expressed by the ovarian tumor.

Second Look Operation

In a single-institution retrospective cohort study, 230 patients were treated for stage III primary ovarian cancer and 175 became eligible for second-look operations by virtue of a complete clinical response after primary surgical cytoreduction and platinum-based combination chemotherapy. Of these, 109 underwent a second-look operation. Optimal primary cytoreduction was defined as residual disease ≤1 cm. Median follow-up was 68.3 months. Five-year survival for all the 230 stage III ovarian cancers was 43.4%. Among all eligible patients (n = 175), there was no survival difference (P = 0.67) in those having second look (57.3%, 5-year survival) versus no second look (48.7%). In those patients with optimal primary cytoreduction (n = 118), there was no survival advantage to second look (69% versus 61%, P = 0.7). However, in those with suboptimal primary cytoreduction (n = 47), 5-year survival was 36% in those having second look versus only 13% in those refusing second look (P < 0.05). Multivariate analysis identified second-look surgery as the only significant independent prognostic variable affecting survival (RR = 0.321, P < 0.04). Patients with suboptimal debulking at primary surgery for stage III ovarian cancer appear to achieve a survival benefit from second-look surgical procedures, presumably from the early identification and treatment of residual disease.
