Evaluation of various kinetic parameters of CA-125 in patients with advanced-stage ovarian cancer undergoing neoadjuvant chemotherapy.

ABSTRACT: Various kinetic parameters of serum CA-125 have been reported to have better correlation with outcomes for patients treated with neoadjuvant chemotherapy (NAC). This study aimed to compare the available kinetic parameters of serum CA-125 in an external cohort of advanced-stage ovarian cancer. Using the cancer registry databases from the Yonsei Cancer Hospital, we retrospectively reviewed 210 patients with advanced-stage ovarian cancer, treated with NAC followed by interval debulking surgery. We compared area under the receiver-operating characteristics curves (AUCs), false negative rate, and negative predictive value (NPV) using 10 different models for optimal cytoreduction and platinum resistance. In addition, we compared incremental AUC for progression-free survival (PFS) and overall survival (OS). No gross residual tumor was observed in 37.0% and residual tumors <1 cm in 82.2% of patients. No model using CA-125 kinetic parameters had an AUC higher than >0.6 for predicting optimal cytoreduction. After adjusting for age, BMI, disease stage, and histologic subtypes, all models had an AUC >0.70 for predicting platinum resistance. However, no model had a high enough NPV (highest value = 82.0%) to avoid chemotherapy futility. For survival outcomes, no model had an incremental AUC >0.70 for predicting either PFS or OS. None of the proposed serum CA-125 kinetic parameters showed high accuracy in predicting optimal cytoreduction, platinum resistance, or survival in patients receiving NAC. For advanced-stage ovarian cancer treated with NAC, there is a need to discover reliable biomarkers to better stratify patient response groups for optimal treatment decision-making.

Project description:ImportanceHyperthermic intraperitoneal chemotherapy (HIPEC) followed by interval cytoreductive surgery (ICS) has shown survival benefits for patients with advanced-stage ovarian cancer. However, there is still a lack of consensus regarding the integration of HIPEC into clinical practice.ObjectiveTo evaluate the safety and effectiveness of ICS with HIPEC compared with ICS alone in clinical practice for patients with advanced-stage ovarian cancer.Design, setting, and participantsThis prospective, multicenter, comparative effectiveness cohort study enrolled 205 patients with stage III or IV ovarian cancer who had received at least 3 cycles of neoadjuvant chemotherapy followed by ICS with HIPEC or ICS without HIPEC at 7 Korean Gynecologic Oncology Group institutions between September 1, 2017, and April 22, 2022. Nine patients were excluded because they did not meet the inclusion criteria.ExposuresNeoadjuvant chemotherapy followed by ICS with HIPEC or ICS without HIPEC.Main outcomes and measuresThe primary end point was progression-free survival (PFS). Overall survival (OS) and the safety profile were the key secondary end points.ResultsThis study included 196 patients (median age, 58.0 years [range, 38-82 years]), of whom 109 underwent ICS with HIPEC and 87 underwent ICS without HIPEC. The median duration of follow-up was 28.2 months (range, 3.5-58.6 months). Disease recurrence occurred in 128 patients (65.3%), and 30 patients (15.3%) died. Interval cytoreductive surgery with HIPEC was associated with a significant improvement in median PFS compared with ICS without HIPEC (22.9 months [95% CI, 3.5-58.6 months] vs 14.2 months [95% CI, 4.0-56.2 months]; P = .005) and median OS (not reached [95% CI, 3.5 months to not reached] vs 53.0 [95% CI, 4.6-56.2 months]; P = .002). The frequency of grade 3 or 4 postoperative complications was similar in both groups (ICS with HIPEC, 3 of 109 [2.8%] vs ICS without HIPEC, 3 of 87 [3.4%]; P > .99). Among patients with recurrence, the frequency of peritoneal recurrence was lower in the ICS with HIPEC group than in the ICS without HIPEC group (21 of 64 [32.8%] vs 41 of 64 [64.1%]; P = .001).Conclusions and relevanceThis study suggests that ICS in conjunction with HIPEC was associated with longer PFS and OS than ICS without HIPEC for patients with advanced-stage ovarian cancer and was not associated with higher rates of postoperative complications. The lower rate of peritoneal recurrence after HIPEC may be associated with improved OS.

Project description:BackgroundNeoadjuvant chemotherapy (NACT) treatment in locoregionally advanced nasopharyngeal carcinoma (LA-NPC) can lead to considerable toxicity. Loss of skeletal muscle mass showed relevance with increased chemotherapy-related toxicity and poor survival in various cancer types, but its significance in NPC remains unclear. This study aimed to investigate the relationship between body composition parameters and the incidence of NACT toxicity in LA-NPC patients.MethodsNinety-six LA-NPC patients were retrospectively enrolled. All patients had pre-treatment abdominal computed tomography (CT) images to exclude distant metastasis. Lean body mass (LBM, kg) was estimated based on cross-sectional muscle area at the third lumbar vertebra (L3) level on CT, and skeletal muscle index (SMI, cm2/m2) was calculated. Doses of chemotherapeutics were normalized as dose/LBM (mg/kg). Grade 3-4 toxicity was defined as severe. The associations between body composition parameters and severe toxicities were assessed using univariate and multivariate logistic regression analyses. Optimal cutoff points were obtained with a receiver operating characteristic (ROC) curve.ResultsOf the 96 patients, 81.2% received the docetaxel + cisplatin (TP) regimen, and the rest received the gemcitabine + cisplatin (GP) regimen. Males had more LBM and a higher SMI at baseline, and females received a markedly higher dose of docetaxel and gemcitabine per kg LBM (P<0.001). With a cutoff value of 52.7 cm2/m2, patients with higher SMI showed lower risk of severe toxicity. For TP regimen group, those presented with grade 3-4 neutropenia had a higher dose per kg LBM. Univariate and multivariate analyses showed that the LBM-adjusted dose was significantly associated with severe neutropenia in the TP regimen group (P<0.001). The LBM-normalized docetaxel cutoff value of 2.64 mg/kg was a prominent predictor of ≥ grade 3 neutropenia (P=0.003), but a higher dose of docetaxel per kg LBM did not provide a better objective response rate.ConclusionsLA-NPC patients with lower SMI and higher dose of docetaxel per kg LBM are more likely to suffer from severe treatment-related toxicity. Higher docetaxel dose per kg LBM is a prominent predictor for severe neutropenia, but not for NACT response. LBM showed good potential in toxicity risk prediction and dose determination.
