Clinical Effect of Adjuvant Cytokine-Induced Killer Cells Immunotherapy in Patients with Stage II-IVB Nasopharyngeal Carcinoma after Chemoradiotherapy: A propensity score analysis.

ABSTRACT: As an adjuvant immunotherapy, cytokine-induced killer cells (CIKs) infusion has been demonstrated to exert potent effectiveness in several types of cancer patients who received curative treatment. However, controversy exists regarding whether nasopharyngeal carcinoma (NPC) patients can benefit from additional treatment after radical radiotherapy or chemoradiotherapy to improve their distant control and survival. In this retrospective study, we aimed to evaluate the efficacy of adjuvant CIK cells therapy in NPC patients with stage II-IVB after curative treatment. From January 1, 2005 to December 31, 2012, 85 pairs of NPC patients matching by propensity score matching (PSM) method to balance prognostic factors were included in this study: 85 cases underwent radical treatment, 85 cases received radical treatment and sequential CIKs infusion. We found that disease-free survival (DFS) and overall survival (OS) were significantly better in the CIK group than that in the control group (P = 0.009, P < 0.001, respectively). Adjuvant CIK cells immunotherapy was showed to be an independent prognostic factor for survival of the patients in further multivariate analysis. In subgroup analyses, the DFS and OS of patients with T3/4, III and IV A-B TNM (tumor-node-metastasis) stages were significantly enhanced in CIK group compared to control group. Nevertheless, both NPC patients with high and low EBV DNA benefited from adjuvant CIK cells immunotherapy. In conclusion, CIKs infusion is an effective adjuvant immunotherapy for enhancing the prognosis of NPC patients who have received the standard treatment, particularly for those with more aggressive tumor (T3/4) or advanced TNM stage.

Project description:BACKGROUND:Promising efficacy and manageable toxicity of docetaxel-based concurrent chemoradiotherapy (CCRT) were reported in head and neck cancer. In addition, the effect of CCRT in combination with cisplatin and/or 5-fluorouracil on both locoregionally advanced and metastatic/recurrent nasopharyngeal carcinoma (NPC) was verified. However, CCRT with docetaxel for locoregionally advanced NPC are not well studied. This study aimed to compare effectiveness and toxicities of CCRT with weekly docetaxel versus tri-weekly cisplatin for locoregionally advanced NPC. METHODS:Clinical data of patients with locoregionally advanced NPC newly diagnosed between January 2010 and December 2014 receiving CCRT with either weekly docetaxel (15 mg/m2) or tri-weekly cisplatin (80-100 mg/m2) were reviewed. Propensity score matching at a 1:1 ratio was performed to balance baseline characteristics. Adverse events and survival were compared between the two groups. RESULTS:A total of 962 patients were included as the whole cohort, and 448 patients were matched and were regarded as the matched cohort. The median follow-up duration was 48 months for the whole cohort. The 3-year nodal recurrence-free survival rate was significantly increased for patients treated with docetaxel in both the whole (hazard ratio [HR] = 0.37, 95% confidence interval [CI] 0.19-0.72, P = 0.030) and matched cohorts (HR = 0.33, 95% CI 0.14-0.79, P = 0.023). However, no significant differences were observed in overall survival, local recurrence-free survival, and distant metastasis-free survival between the two groups in both cohorts. Significantly higher rates of grade 3 radiodermatitis (6.7% vs. 1.8%, P = 0.001), mucositis (74.5% vs. 37.9%, P < 0.001), and leucopenia (2.2% vs. 11.6%, P < 0.001) were observed in the docetaxel group, but any grade of renal injury (1.8% vs. 15.1%, P < 0.001), vomiting (18.8% vs. 88.3%, P < 0.001), and ALT elevation (19.2% vs. 31.3%, P = 0.027) were more common in the cisplatin group. CONCLUSIONS:CCRT with weekly low-dose docetaxel is an effective and tolerable therapeutic regimen for locally advanced NPC. It provides a survival benefit mainly by improving the control of regional lymph node metastases, especially for patients with low pretreatment EBV DNA levels.

Project description:ImportanceDistant recurrence following preoperative chemoradiotherapy and resection in patients with gastroesophageal adenocarcinoma is common. Adjuvant chemotherapy may improve survival.ObjectiveTo compare adjuvant chemotherapy with postoperative observation following preoperative chemoradiotherapy and resection in patients with gastroesophageal adenocarcinoma.Design, setting, and participantsPropensity score-matched analysis using the National Cancer Database. We included adult patients who received a diagnosis between 2006 and 2013 of clinical stage T1N1-3M0 or T2-4N0-3M0 adenocarcinoma of the distal esophagus or gastric cardia who were treated with preoperative chemoradiotherapy and curative-intent resection. Patients receiving adjuvant chemotherapy were matched by propensity score to patients undergoing postoperative observation.ExposuresAdjuvant chemotherapy and postoperative observation.Main outcomes and measuresOverall survival.ResultsWe identified 10?086 patients (8840 [88%] male; mean [SD] age, 61 [9.5] years), 9272 in the postoperative observation group and 814 in the adjuvant chemotherapy group. Patients receiving adjuvant chemotherapy were younger (18-54 years: 252 [31%] vs 1989 [21%]; P?<?.001) and were more likely to have advanced disease (ypT3/4: 458 [62%] vs 3531 [46%]; P?<?.001; ypN+: 572 [72%] vs 3428 [39%]; P?<?.001), as well as shorter postoperative inpatient stays (>2 weeks: 94 [13%] vs 1589 [20%]; P?<?.001). A total of 732 patients in the adjuvant chemotherapy group were matched by propensity score to 3660 patients in the postoperative observation group. Adjuvant chemotherapy was associated with improved overall survival compared with postoperative observation (median survival: 40 months; 95% CI, 36-46 months vs 34 months; 95% CI, 32-35 months; stratified log-rank P?<?.001; hazard ratio, 0.79; 95% CI, 0.72-0.88). Overall survival at 1, 3, and 5 years was 88%, 47%, and 34% in the observation group, and 94%, 54%, and 38% in the adjuvant chemotherapy group, respectively. Adjuvant chemotherapy was associated with a survival benefit compared with postoperative observation in most patient subgroups.Conclusions and relevanceFor patients with locally advanced gastroesophageal adenocarcinoma treated with preoperative chemoradiotherapy and resection, adjuvant chemotherapy was associated with improved overall survival. Our findings have important implications for the postoperative treatment of this patient group for which few data are available.
