Abstract
Background We compared the relative benefits, harms and cost-effectiveness of hyperthermic intraoperative peritoneal chemotherapy + cytoreductive surgery ± systemic chemotherapy versus cytoreductive surgery ± systemic chemotherapy or systemic chemotherapy alone in people with peritoneal metastases from colorectal, gastric or ovarian cancers by a systematic review, meta-analysis and model-based cost-utility analysis. Methods We searched MEDLINE, EMBASE, Cochrane Library and the Science Citation Index, ClinicalTrials.gov and WHO ICTRP trial registers until 14 April 2022. We included only randomised controlled trials addressing the research objectives. We used the Cochrane risk of bias tool version 2 to assess the risk of bias in randomised controlled trials. We used the random-effects model for data synthesis when applicable. For the cost-effectiveness analysis, we performed a model-based cost-utility analysis using methods recommended by The National Institute for Health and Care Excellence. Results The systematic review included a total of eight randomised controlled trials (seven randomised controlled trials, 955 participants included in the quantitative analysis). All comparisons other than those for stage III or greater epithelial ovarian cancer contained only one trial, indicating the paucity of randomised controlled trials that provided data. For colorectal cancer, hyperthermic intraoperative peritoneal chemotherapy + cytoreductive surgery + systemic chemotherapy probably results in little to no difference in all-cause mortality (60.6% vs. 60.6%; hazard ratio 1.00, 95% confidence interval 0.63 to 1.58) and may increase the serious adverse event proportions compared to cytoreductive surgery ± systemic chemotherapy (25.6% vs. 15.2%; risk ratio 1.69, 95% confidence interval 1.03 to 2.77). Hyperthermic intraoperative peritoneal chemotherapy + cytoreductive surgery + systemic chemotherapy probably decreases all-cause mortality compared to fluorouracil-based systemic chemotherapy alone (40.8% vs. 60.8%; hazard ratio 0.55, 95% confidence interval 0.32 to 0.95). For gastric cancer, there is high uncertainty about the effects of hyperthermic intraoperative peritoneal chemotherapy + cytoreductive surgery + systemic chemotherapy versus cytoreductive surgery + systemic chemotherapy or systemic chemotherapy alone on all-cause mortality. For stage III or greater epithelial ovarian cancer undergoing interval cytoreductive surgery, hyperthermic intraoperative peritoneal chemotherapy + cytoreductive surgery + systemic chemotherapy probably decreases all-cause mortality compared to cytoreductive surgery + systemic chemotherapy (46.3% vs. 57.4%; hazard ratio 0.73, 95% confidence interval 0.57 to 0.93). Hyperthermic intraoperative peritoneal chemotherapy + cytoreductive surgery + systemic chemotherapy may not be cost-effective versus cytoreductive surgery + systemic chemotherapy for colorectal cancer but may be cost-effective for the remaining comparisons. Limitations We were unable to obtain individual participant data as planned. The limited number of randomised controlled trials for each comparison and the paucity of data on health-related quality of life mean that the recommendations may change as new evidence (from trials with a low risk of bias) emerges. Conclusions In people with peritoneal metastases from colorectal cancer with limited peritoneal metastases and who are likely to withstand major surgery, hyperthermic intraoperative peritoneal chemotherapy + cytoreductive surgery + systemic chemotherapy should not be used in routine clinical practice (strong recommendation). There is considerable uncertainty as to whether hyperthermic intraoperative peritoneal chemotherapy + cytoreductive surgery + systemic chemotherapy or cytoreductive surgery + systemic chemotherapy should be offered to patients with gastric cancer and peritoneal metastases (no recommendation). Hyperthermic intraoperative peritoneal chemotherapy + cytoreductive surgery + systemic chemotherapy should be offered routinely to women with stage III or greater epithelial ovarian cancer and metastases confined to the abdomen requiring and likely to withstand interval cytoreductive surgery after chemotherapy (strong recommendation). Future work More randomised controlled trials are necessary. Study registration This study is registered as PROSPERO CRD42019130504.

J Ovarian Res 2021; 14:93. [PMID: 34256813 PMCID: PMC8278673 DOI: 10.1186/s13048-021-00842-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Accepted: 06/29/2021] [Indexed: 01/09/2023] Open
Abstract
Objective The aim of this meta-analysis was to assess the effectiveness and safety of secondary cytoreductive surgery plus chemotherapy (SCS + CT) in recurrent ovarian cancer (ROC). Our secondary purpose was to analyze whether patients could benefit from complete resection. Methods We searched EMBASE, MEDLINE, the Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials, from inception to April 2021. We used appropriate scales to assess the risk of bias. Data from included studies that reported median PFS or OS were weighted by individual study sample size, and aggregated for meta-analysis. We calculated the pooled proportion of complications within 30 days after surgery. Results We identified 13 articles, including three RCTs and ten retrospective cohort studies. A total of 4572 patients were included, of which 916 patients achieved complete resection, and all patients were comparable at baseline. Compared with chemotherapy alone, SCS + CT significantly improved the PFS (HR = 0.54, 95% CI: 0.43–0.67) and OS (HR = 0.60, 95% CI: 0.44–0.81). Contrary to the results of cohort studies, the meta-analysis of RCTs showed that SCS + CT could not bring OS benefits (HR = 0.93, 95% CI: 0.66–1.3). The subgroup analysis showed the prognostic importance of complete resection. Compared with chemotherapy alone, complete resection was associated with longer PFS (HR = 0.53, 95% CI: 0.45–0.61) and OS (HR = 0.56, 95% CI: 0.39–0.81), while incomplete resection had no survival benefit. Additionally, complete resection could maximize survival benefit compared with incomplete resection (HR = 0.56, 95% CI: 0.46–0.69; HR = 0.61, 95% CI: 0.50–0.75). The pooled proportion for complications at 30 days was 21% (95% CI: 0.12–0.30), and there was no statistical difference in chemotherapy toxicity between the two groups. Conclusion The review indicated that SCS + CT based regimens was correlated with better clinical prognosis for patients with recurrent ovarian cancer, but the interpretation of OS should be cautious. The meta-analysis emphasizes the importance of complete resection, suggesting that the potential benefits of prolonging survival may outweigh the disadvantages of any short-term complications associated with surgery.

Abstract
Epithelial ovarian cancer is the most common cause of death from gynecological tumors. Most patients with advanced ovarian cancer develop recurrence after concluding first-line therapy, making further lines of therapy necessary. The choice of therapy depends on various criteria such as tumor biology, the patient's general condition (ECOG), toxicity, previous chemotherapy, and response to chemotherapy. The platinum-free or treatment-free interval determines the potential response to repeat platinum-based therapy. If patients have late recurrence, i.e. > 6 months after the end of the last platinum-based therapy (i.e., they were previously platinum-sensitive), then they are usually considered suitable for another round of a platinum-based combination therapy. Patients who are not considered suitable for platinum-based chemotherapy are treated with a platinum-free regimen such as weekly paclitaxel, pegylated liposomal doxorubicin (PLD), gemcitabine, or topotecan. Treatment for the patient subgroup which is considered suitable for platinum-based therapy but cannot receive carboplatin due to uncontrollable hypersensitivity reactions may consist of trabectedin and PLD. While the use of surgery to treat recurrence has long been a controversial issue, new findings from the DESKTOP III study of the AGO working group have drawn attention to this issue again, particularly for patients with a platinum-free interval of > 6 months and a positive AGO score. Clinical studies have also shown the efficacy of angiogenesis inhibitors such as bevacizumab and the PARP inhibitors olaparib, niraparib and rucaparib. These drugs have substantially changed current treatment practice and expanded the range of available therapies. It is important to differentiate between purely maintenance therapy after completing CTX, continuous maintenance therapy during CTX, and the therapeutic use of these substances. The PARP inhibitors niraparib, olaparib and rucaparib have already been approved for use by the FDA and the EMA. The presence of a BRCA mutation is a predictive factor for a better response to PARP inhibitors.

Abstract
BACKGROUND The prognostic value and optimal resection outcome related factors of the secondary cytoreduction surgery (SCR) in Platinum-sensitive recurrent ovarian cancer (PSOC) patients were still in doubt. The present retrospective study aims to determine the relationship between the objective response of secondary neo-adjuvant chemotherapy (SNAC) and the resection outcome of SCR. METHODS Data were reviewed from 142 type II PSOCs who underwent SCR in Jiangsu Institute of Cancer Research between 1996 and 2016. Among them, 55 cases received preliminary Platinum based SNAC before SCR. Logistic regression analysis was used to explore optimal SCR related factors. Cox proportional hazards model and log-rank test were used to assess the associations between the survival durations and covariates. RESULTS Optimal initial CRS (p = 0.02), disappearance of ascites after SNAC (p = 0.04) recurrent status (p = 0.02) and longer Platinum-free interval (p = 0.01) were the independent indicators of optimal SCR. Optimal SCR was associated with time to progression (TTP) but not overall survival (OS) (p = 0.04 and p = 0.41). The TTP and OS of PSOCs underwent SNAC were similar to those patients underwent SCR (p = 0.71, and p = 0.77, respectively) directly. CONCLUSIONS SNAC might be another choice for PSOCs were not suitable for directly SCR. Optimal SCR had survival benefit in PSOCs whenever underwent SNAC or not.

Outcomes of secondary cytoreductive surgery for patients with platinum-sensitive recurrent ovarian cancer. Am J Obstet Gynecol 2019; 221:625.e1-625.e14. [PMID: 31207237 DOI: 10.1016/j.ajog.2019.06.009] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2019] [Revised: 06/06/2019] [Accepted: 06/10/2019] [Indexed: 01/28/2023]
Abstract
BACKGROUND Most women with advanced epithelial ovarian cancer develop recurrent disease, despite maximal surgical cytoreduction and adjuvant platinum-based chemotherapy. In observational studies, secondary cytoreductive surgery has been associated with improved survival; however its use is controversial, because there are concerns that the improved outcomes may reflect selection bias rather than the superiority of secondary surgery. OBJECTIVE To compare the overall survival of women with platinum-sensitive recurrent ovarian cancer treated at National Cancer Institute-designated cancer centers who receive secondary surgery vs chemotherapy. STUDY DESIGN This retrospective cohort study included women from 6 National Cancer Institute-designated cancer centers diagnosed with platinum-sensitive recurrent ovarian cancer between January 1, 2004, and December 31, 2011. The primary outcome was overall survival. Propensity score matching was used to compare similar women who received secondary surgery vs chemotherapy. Additional analyses examined how these findings may be influenced by the prevalence of unobserved confounders at the time of recurrence. RESULTS Among 626 women, 146 (23%) received secondary surgery and 480 (77%) received chemotherapy. In adjusted analyses, patients who received secondary surgery were younger (P = 0.001), had earlier-stage disease at diagnosis (P = 0.002), and had longer disease-free intervals (P < 0.001) compared with those receiving chemotherapy. In the propensity score-matched groups (n = 244 patients), the median overall survival was 54 months in patients who received secondary surgery and 33 months in those treated with chemotherapy (P < 0.001). Among patients who received secondary surgery, 102 (70%) achieved optimal secondary cytoreduction. There were no significant differences in complication rates between the 2 groups. In sensitivity analyses, the survival advantage associated with secondary surgery could be explained by the presence of more multifocal recurrences (if 4.3 times more common), ascites (if 2.7 times more common), or carcinomatosis (if 2.1 times more common) among patients who received chemotherapy instead of secondary surgery. CONCLUSION Patients with platinum-sensitive recurrent ovarian cancer who received secondary surgery had favorable surgical characteristics and were likely to have minimal residual disease following secondary surgery. These patients had a superior median overall survival compared with patients who received chemotherapy, although unmeasured confounders may explain this observed difference.

Abstract
Objective Accumulating evidence support that complete cytoreduction (CC) at the time of secondary cytoreductive surgery (SCS) improves survival in patients affected by recurrent ovarian cancer (ROC). Here, we aimed to determine whether artificial intelligence (AI) might be useful in weighting the importance of clinical variables predicting CC and survival. Methods This is a retrospective study evaluating 194 patients having SCS for ROC. Using artificial neuronal network (ANN) analysis was estimated the importance of different variables, used in predicting CC and survival. ANN simulates a biological neuronal system. Like neurons, ANN acquires knowledge through a learning-phase process and allows weighting the importance of covariates, thus establishing how much a variable influences a multifactor phenomenon. Results Overall, 82.9% of patients had CC at the time of SCS. Using ANN, we observed that the 3 main factors driving the ability of achieve CC included: disease-free interval (DFI) (importance: 0.231), retroperitoneal recurrence (importance: 0.178), residual disease at primary surgical treatment (importance: 0.138), and International Federation of Gynecology and Obstetrics (FIGO) stage at presentation (importance: 0.088). Looking at connections between different covariates and overall survival (OS), we observed that DFI is the most important variable influencing OS (importance: 0.306). Other important variables included: CC (importance: 0.217), and FIGO stage at presentation (importance: 0.100). Conclusion According to our results, DFI should be considered as the most important factor predicting both CC and OS. Further studies are needed to estimate the clinical utility of AI in providing help in decision making process.

Abstract
STUDY OBJECTIVE To analyze the feasibility and safety of laparoscopic secondary cytoreductive surgery in a retrospective series of patients with platinum-sensitive recurrent ovarian cancer. DESIGN Retrospective cohort study (Canadian Task Force classification II-2). SETTING Catholic University of the Sacred Heart, Rome, Italy. PATIENTS Between October 2010 and October 2016, 58 patients with recurrent ovarian cancer were selected for a retrospective analysis of data. INTERVENTIONS All patients underwent a laparoscopic secondary cytoreduction with single or multiple procedures. RESULTS The most frequent pattern of recurrence was peritoneal (48.3%); 6 patients (10.3%) experienced parenchymal disease (spleen, n = 5; liver, n = 1), and 24 patients (41.4%) had lymph node recurrence. Complete debulking was achieved in all patients. The median operative time was 204 minutes (range, 55-448 minutes), median estimated blood loss was 70 mL (range, 20-300 mL), and the median length of hospital stay was 4 days (range, 1-21 days). Four patients (6.8%) experienced intraoperative complications. Early postoperative complications were documented in 6 patients (10.3%), but only 1 G3 complication was noted. The median duration of follow-up since secondary cytoreduction was 24 months (range, 9-71 months). Twenty-one patients (36.2%) experienced a second disease relapse. The median progression-free survival (PFS) was 28 months, and the 2-year PFS was 58.7%. Five patients died (8.6%); the 2-year overall survival was 90.7%. CONCLUSIONS For selected patients, laparoscopy is a feasible and safe approach to optimal cytoreduction for patients with recurrent ovarian cancer.
