晚期卵巢癌新辅助化疗前后CA125的变化与减瘤满意率及预后相关性分析

目的:探讨晚期卵巢癌患者新辅助化疗前后血CA125值的变化与减瘤满意率及预后的关系。方法:回顾性分析蚌埠医学院第一附属医院肿瘤妇科经盆腔肿块穿刺送病理确诊为卵巢癌并行1~2个周期新辅助化疗后再行肿瘤细胞减灭术的70例晚期卵巢癌患者的临床病例资料,分析初次诊治时血CA125值、新辅助化疗后血CA125的下降率、术前血CA125值与减瘤满意率及预后的关系。结果:t检验及卡方检验提示,1~2个周期新辅助化疗后,血CA125下降率及术前血CA125水平影响患者减瘤的满意率。术前CA125≤150 U/ml组与＞150 U/ml组的减瘤满意率比较,差异有统计学意义(P＜0.05),两者生存率比较,差异无统计学意义（P＞0.05）。血CA125 的下降率≥80%组与＜80%组的减瘤满意率比较,差异有统计学意义(P＜0.05)。结论:1~2个周期新辅助化疗后,血CA125的下降率及术前血CA125水平可预测患者手术的切净率,术前血清CA125是否≤150 U/ml及血CA125的下降率是否≥80%可用于初步判断减瘤满意率,但不能预测患者的预后。     

晚期卵巢癌肿瘤细胞减灭术术前选择新辅助化疗的评估

卵巢癌是妇科三大肿瘤之一。因卵巢位于盆腔深部，卵巢癌患者多无明显症状，察觉时已是晚期。晚期卵巢癌恶性程度高，预后差，手术辅以化疗是目前主要治疗手段，手术中尽可能切除肿瘤、缩小残留病灶达到理想肿瘤细胞减灭术以延长生存期、改善预后。对于无法手术的晚期卵巢癌患者，新辅助化疗能够改善手术条件．增加手术满意度，是可行的治疗方案。因此，术前对晚期卵巢癌患者手术可行性进行评估，予以患者正确的首选治疗方案，提高手术满意度，避免不必要的剖腹探查。目前用以晚期卵巢癌肿瘤细胞减灭术术前评估的方法有1）影像学检查．如CT、PET，MRI等；2）CA125值，根据CA125值的高低评估手术可行性；3）腹腔镜探查，根据术中所见评估开腹手术可行性；4）其他各种肿瘤标记物如p53。各研究中探讨的手术评估手段大多局限于某一个方面。未能将有意义的预测因素全部纳入进行综合分析，准确性尚存在不足。探索新的方式方法．或是交叉应用两种或两种以上评估手段对晚期卵巢癌肿瘤细胞减灭术可行性进行综合评估，提高手术满意程度，缩小残留病灶，达到延长晚期卵巢癌患者生存时间和改善晚期预后的目的。本文就晚期卵巢癌肿瘤细胞减灭术可行性的评估和新辅助化疗的选择进行综述．

Primary debulking surgery or neoadjuvant chemotherapy followed by interval debulking surgery for patients with advanced ovarian cancer

Objectives:To compare the survival and perioperative morbidity between primary debulking surgery(PDS) and neoadjuvant chemotherapy followed by interval debulking surgery(NAC/IDS) in treating patients with advanced epithelial ovarian cancer(EOC).Methods:We retrospectively reviewed 67 patients with stage IIIC or IV EOC treated at Peking University Cancer Hospital from January 2006 to June 2009.Wherein,37 and 30 patients underwent PDS and NAC/IDS,respectively.Results:No difference in overall survival(OS) or progression-free survival(PFS) was observed between NAC/IDS group and PDS group(OS:41.2 vs.39.1 months,P=0.23;PFS:27.1 vs.24.3 months,P=0.37).The optimal debulking rate was 60% in the NAC/IDS group,which was significantly higher than that in the PDS group(32.4%)(P=0.024).The NAC/IDS group had significantly less intraoperative estimated blood loss and transfusion,lower nasogastric intubation rate,and earlier ambulation and recovery of intestinal function than the PDS group(P<0.05).Conclusions:NAC/IDS is less invasive than PDS,and offers the advantages regarding optimal cytoreduction rate,intraoperative blood loss,and postoperative recovery,without significantly impairing the survival compared with PDS in treating patients with stage IIIC or IV EOC.Therefore,NAC/IDS may be a valuable treatment alternative for EOC patients.     

Comparison of treatment invasiveness between upfront debulking surgery versus interval debulking surgery following neoadjuvant chemotherapy for stage III/IV ovarian,tubal, and peritoneal cancers in a phase III randomised trial: Japan Clinical Oncology Group Study JCOG0602

BackgroundWe conducted a phase III, non-inferiority trial comparing upfront primary debulking surgery (PDS) and interval debulking surgery (IDS) following neoadjuvant chemotherapy (NAC) for stage III/IV ovarian, tubal, and peritoneal cancers (JCOG0602). Two earlier studies, EORTC55971 and CHORUS, demonstrated non-inferior survival of patients treated with NAC. However, they could not evaluate true treatment invasiveness because of adding diagnostic laparotomy or laparoscopy before treatment in over 30% of both arms of EORTC55971 and in 16% of NAC arm of CHORUS.MethodsPatients were randomised into the standard arm (PDS followed by eight cycles of paclitaxel and carboplatin [TC]) and NAC arm (four cycles of TC, IDS, and four cycles of TC). In the standard arm, IDS was optional for patients who had undergone suboptimal or incomplete PDS. Treatment invasiveness was compared between arms (UMIN000000523).ResultsBetween November 2006 and October 2011, 301 patients were randomised. In the standard arm, 147/149 underwent PDS and 49 underwent IDS. In the NAC arm, 130/152 underwent IDS. The NAC arm required fewer surgeries (mean 0.86 versus 1.32, p < 0.001) and shorter total operation time (median 273 min versus 341 min, p < 0.001) than the standard arm and required a lower frequency of abdominal organ resection (23.7% versus 37.6%, p = 0.012) or distant metastases resection (3.9% versus 10.7%, p = 0.027). In the NAC arm IDS, blood/ascites loss was smaller (median 787 ml versus 3235 ml, p < 0.001) and albumin transfusion and G3/4 adverse events after surgery in total were less frequent (26.2% versus 58.5%, p < 0.001; 4.6% versus 15.0%, p = 0.005, respectively).ConclusionOur findings demonstrated that NAC treatment is less invasive than standard treatment. NAC treatment may become the new standard treatment for advanced ovarian cancer when non-inferior survival is confirmed in the planned primary analysis in 2017.     

Results of interval debulking surgery in advanced stage ovarian cancer: an exposed-non-exposed study.

BACKGROUND: To study the results of interval debulking surgery (IDS) in patients treated for 'unresectable' advanced stage ovarian cancer compared with primary debulking surgery (PDS) followed by chemotherapy. PATIENTS AND METHODS: An exposed-non-exposed study including a group of 34 patients who underwent an IDS and were matched to an historic control group of 34 patients treated with PDS. RESULTS: Optimal cytoreductive surgery was achieved in 94% (32 out of 34) of patients in both groups. The rates of post-operative morbidity, blood transfusion and median length of hospitalisation were significantly reduced in the study (IDS) group, but survival did not differ in both groups. CONCLUSIONS: IDS in patients with advanced stage ovarian cancer offers the same chance of survival as PDS, but it is better tolerated.     

Phase III trial of upfront debulking surgery versus neoadjuvant chemotherapy for stage III/IV ovarian, tubal and peritoneal cancers: Japan Clinical Oncology Group Study JCOG0602

On the basis of promising results of neoadjuvant chemotherapy (NAC) in our previous study (JCOG0206), we have been performing a Phase III study of treatment starting with NAC versus standard treatment starting with primary debulking surgery (PDS) for Stage III/IV müllerian carcinomas (ovarian, tubal and peritoneal carcinomas) since November 2006. The purposes are to prove the non-inferiority of the efficacy and to show the decrease in adverse effects resulting from reduced surgical invasiveness of treatment starting with NAC. Three hundred patients with advanced müllerian carcinomas will be randomized during 3 years. NAC arm patients undergo four cycles of NAC with paclitaxel plus carboplatin followed by interval debulking surgery and an additional four cycles of postsurgical chemotherapy. Standard arm patients undergo PDS and eight cycles of postsurgical chemotherapy with or without interval debulking surgery. The primary endpoint is overall survival. The major secondary endpoints are the incidence of adverse events and parameters representing surgical invasiveness.     

Asian perspective on debulking surgery for advanced ovarian cancer: An E-survey

PurposeWe performed an E-survey to evaluate the practice patterns in debulking surgery for advanced ovarian cancer in Asia.MethodsWe designed a questionnaire, including 50 questions related to debulking surgery for advanced ovarian cancer. The questionnaire was sent to Gynecologic Oncologic Groups in Asia from December 2016 to February 2017.ResultsA total of 253 gynecologic oncologists from Japan (58.9%), the Republic of Korea (19%), Taiwan (12.6%), and the other counties including China (7.5%), Malaysia (0.8%), Indonesia (0.8%), and Thailand (0.4%) participated in this E-survey. The median number of debulking surgeries per year was 20, and 46.8% of the respondents preferred <1 cm as the criterion for optimal debulking surgery (ODS). The most common barrier and surgical finding precluding ODS were performance status (74.3%) and disease involving the porta hepatis (71.5%). Moreover, 63.2% had a fellowship program, and only 15% or less had opportunities to receive additional training courses in general, thoracic, or urologic surgery. The median percentage of patients receiving neoadjuvant chemotherapy (NAC) was 30%, and the achieved rate of ODS in primary debulking surgery (PDS) and interval debulking surgery (IDS) was 65% and 80%, respectively. Most of the respondents required three to 6 h for PDS (48.6%) and IDS (58.9%). Moreover, more than 50% depended on ultra-radical surgery conducted by specialists.ConclusionsThe ODS criteria are relatively lenient with a preference for NAC in 30% of the respondents in Asia. This trend might be associated with the dependence on aggressive surgery performed by specialists.     

Total Colectomy as a Part of Ultra-Radical Surgery for Ovarian Cancer—Short- and Long-Term Outcomes

(1) Background: The aim of this study was to assess the outcomes for patients who underwent total colectomy (TC) as a part of surgery for ovarian cancer (OC). (2) Methods: We performed a retrospective analysis of 1636 OC patients. Residual disease (RD) was reported using Sugarbaker’s completeness of cytoreduction score. (3) Results: Forty-two patients underwent TC during primary debulking surgery (PDS), and four and ten patients underwent TC during the interval debulking surgery (IDS) and secondary cytoreduction, respectively. The median overall survival (mOS) in OC patients following the PDS was 45.1 months in those with CC-0 (21%) resection, 11.1 months in those with CC-1 (45%) resection and 20.0 months in those with CC-2 (33%) resection (p = 0.28). Severe adverse events were reported in 18 patients (43%). In the IDS group, two patients survived more than 2 years after IDS and one patient died after 28.6 months. In the recurrent OC group, the mOS was 6.9 months. Patient age above 65 years was associated with a shortened overall survival (OS) and the presence of adverse events. (4) Conclusions: TC as a part of ultra-radical surgery for advanced OC results in high rates of optimal debulking. However, survival benefits were observed only in patients with no macroscopic disease.     

Serum HE4 superior to CA125 in predicting poorer surgical outcome of epithelial ovarian cancer

Epithelial ovarian cancer (EOC) remains the deadliest form of gynecological cancers. Optimal tumor debulking, no matter the primary or the interval, is the most important prognostic factor for EOC, so there is an urgent demand for biomarkers to predict surgical outcome. The aim of this study was to investigate whether serum human epididymis protein 4 (HE4) and cancer antigen 125 (CA125) could predict surgical outcome of EOC. The levels of preoperative serum HE4 and CA125 were determined by electrochemiluminescence (ECLIA) in 82 EOC patients, comprising 39 subjected to primary debulking surgery (PDS) and 43 with extensive stage III or IV disease to neoadjuvant chemotherapy followed by interval debulking surgery (NACT-IDS). Among 39 patients subjected to primary debulking surgery, HE4 was superior to CA125 in predicting surgical outcome (area under curve [AUC] 0.758 vs. 0.633). At a cutoff of 353.22 pmol/L, HE4 reached 77.4 % in sensitivity and 75 % in specificity. The prediction of surgical outcome of interval debulking surgery based on preoperative HE4 and CA125 values was performed in 43 patients who received NACT-IDS. The difference of AUC between HE4 and CA125 (0.793 vs. 0.663) indicating that HE4 was the better biomarker to predict surgical outcome of IDS. A pre-IDS HE4 value of 154.3 pmol/L is the optimal cutoff to identify patients who would not benefit from IDS with a sensitivity of 92.9 % and a specificity of 69 %. The change (>70 %) of HE4 before and after neoadjuvant chemotherapy could predict optimal interval debulking surgery. Serum HE4 was superior to CA125 in predicting surgical outcome of primary debulking surgery and interval debulking surgery. The change (absolute value or percentage) of HE4 in neoadjuvant chemotherapy could predict the outcome of interval debulking surgery.

     

Effect of tumor burden and radical surgery on survival difference between upfront,early interval or delayed cytoreductive surgery in ovarian cancer

ObjectiveWe sought to evaluate the impact on survival of tumor burden and surgical complexity in relation to the number of cycles of neoadjuvant chemotherapy (NACT) in patients with advanced ovarian cancer (OC) with minimal (CC-1) or no residual disease (CC-0).MethodsThis retrospective study included patients with International Federation of Gynaecology and Obstetrics IIIC–IV stage OC who underwent debulking surgery at 4 high-volume institutions between January 2008 and December 2015. We assessed the overall survival (OS) of primary debulking surgery (PDS group), early interval debulking surgery after 3–4 cycles of NACT (early IDS group) and delayed debulking surgery after 6 cycles (DDS group) with CC-0 or CC-1 according to peritoneal cancer index (PCI) and Aletti score.ResultsFive hundred forty-nine women were included: 175 (31.9%) had PDS, 224 (40.8%) early IDS and 150 (27.3%) DDS. Regardless of Aletti score, median OS after PDS was significantly higher than after early IDS or DDS, but the survival difference was higher in women with an Aletti score <8. Among patients with PCI ≤10, median OS after PDS was significantly higher than after early IDS or DDS. In women with PCI >10, there were no differences between PDS and early IDS, but DDS was associated with decreased OS.ConclusionThe benefit of complete PDS compared with NACT was maximal in patients with a low complexity score. In patients with low tumor burden, there was a survival benefit of PDS over early IDS or DDS. In women with high tumor load, DDS impaired the oncological outcome.     

Efficacy and safety of bevacizumab-containing neoadjuvant therapy followed by interval debulking surgery in advanced ovarian cancer: Results from the ANTHALYA trial

AimTo investigate whether adding bevacizumab to neoadjuvant carboplatin-paclitaxel (CP) helps achieve optimal debulking, measured by complete resection rate (CRR) at interval debulking surgery (IDS), in patients with initially unresectable International Federation of Gynecology and Obstetrics stage IIIC/IV ovarian, tubal or peritoneal adenocarcinoma.MethodsMulticentre, open-label, non-comparative phase II study. Ninety-five patients randomised (2:1) to receive four cycles of neoadjuvant CP ±3 concomitant cycles of bevacizumab 15 mg/kg (BCP) followed by IDS. Primary objective is to evaluate the CRR at IDS in the BCP group (reference CRR rate defined as 45% CRR). A stopping rule based on bevacizumab-related adverse events (AEs) of special interest was implemented.ResultsIn the BCP group (N = 58), IDS was performed in 40 (69%) patients, of whom 85% had a complete resection. The CRR of this group was therefore 58.6% (34 patients), statistically over pre-defined 45%. The CRR in the CP group was 51.4%: 22 (60%) patients underwent IDS (85% had a complete resection). Grade ≥3 adverse events occurred in 62% of the BCP-treated patients and 63% of the CP-treated patients: mainly blood and lymphatic, gastrointestinal and vascular disorders, without more toxicity with BCP. Postoperative complications (mainly wound, infectious and gastrointestinal complications) occurred in 28% and 36% of the patients, respectively. The pre-specified safety stopping rule was not reached.ConclusionThe primary objective was met as the CRR with BCP was significantly higher than the reference rate. Bevacizumab may be safely added to a preoperative program in patients deemed non-optimally resectable, whatever the final surgical decision. Bevacizumab's role in this setting should be further investigated.     

Preoperative Serum CA-125 Level As a Predictor for The Extent of Cytoreduction in Patients with Advanced Stage Epithelial Ovarian Cancer

BackgroundOvarian cancer is the seventh most common cancer in women worldwide and the eighth most common cause of cancer death. Due to the lack of effective early detection strategies and the unspecific onset of symptoms, it is diagnosed at an advanced stage in 75% of cases. The cancer antigen (CA) 125 is used as a prognostic marker and its level is elevated in more than 85% of women with advanced stages of epithelial ovarian cancer (EOC). The standard treatment is primary debulking surgery (PDS) followed by adjuvant chemotherapy (ACT), but the later approach is neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS). Several studies have been conducted to find out whether preoperative CA-125 serum levels influence treatment choice, surgical resection and survival outcome. The aim of our study was to analyse experience of single institution as Cancer comprehensive center with preoperative usefulness of CA-125.Patients and methodsAt the Institute of Oncology Ljubljana a retrospective analysis of 253 women with stage FIGO IIIC and IV ovarian cancer was conducted. Women were divided into two groups based on their primary treatment. The first group was the NACT group (215 women) and the second the PDS group (38 women). The differences in patient characteristics were compared using the Chi-square test and ANOVA and the Kaplan-Meier method was used for calculating progression-free survival (PFS) and overall survival (OS).ResultsThe median serum CA-125 level was higher in the NACT group than in the PDS group, 972 IU/ml and 499 IU/ ml, respectively. The PFS in the NACT group was 8 months (95% CI 6.4–9.5) and 18 months (95% CI 12.5–23.4) in the PDS group. The median OS was lower in the NACT group than in the PDS group, 25 months (95% CI 20.6–29.5) and 46 months (95% CI 32.9–62.1), respectively.ConclusionsPreoperative CA-125 cut off value of 500 IU/ml is a promising threshold to predict a successful PDS.Key words: ovarian cancer, tumour marker, CA-125, primary debulking surgery, neoadjuvant chemotherapy
