Background: This study aimed to investigate the efficiency and toxicities of concurrent chemoradiotherapy (CCRT) and induction chemotherapy (IC) followed by radiotherapy (RT) in different risk locoregionally advanced nasopharyngeal carcinoma (NPC). Methods: A total of 1814 eligible patients with stage II–IVB disease treated with CCRT or IC plus RT were included. The overall survival (OS), progression-free survival (PFS) and distant metastasis-free survival (DMFS) were calculated using the Kaplan–Meier method, and the differences were compared using the log-rank test. Results: Nomograms were developed to predict OS, PFS and DMFS (C-index: 0.71, 0.70 and 0.71, respectively). Patients were then divided into three different risk groups based on the scores calculated by the nomogram for OS. In the low and intermediate-risk group, no significant survival differences were observed between patients treated with IC plus RT alone and CCRT (5-year OS, 97.3% versus 95.6%, p = 0.642 and 87.6% versus 89.7%, p = 0.381, respectively; PFS, 95.9% versus 95.6%, p = 0.325 and 87.6% versus 89.0%, p = 0.160, respectively; DMFS, 97.2% versus 94.8%, p = 0.339 and 87.2% versus 89.3%, p = 0.628, respectively). However, in the high-risk group, IC plus RT displayed an unfavorable 5-year OS (71.0% versus 77.2%, p = 0.022) and PFS (69.4.0% versus 75.4%, p = 0.019) compared with CCRT. A significantly higher incidence of grade 3 and 4 adverse events was documented in patients treated with CCRT than in those treated with IC plus RT in all risk groups ( p = 0.040). Conclusion: IC followed by RT represents an alternative treatment strategy to CCRT for patients with low and intermediate-risk NPC, but it is not recommended for patients with high-risk NPC.

Background: The aim of this study was to evaluate the benefits from the addition of induction chemotherapy (IC) to concurrent chemoradiotherapy (CCRT) in N2-3 nasopharyngeal carcinoma (NPC). Methods: A total of 3089 patients with nonmetastatic NPC, staged as N2-3 were retrospectively reviewed. IC contained cisplatin (80 mg/m2) with 5-fluorouracil (800 mg/m2/day over 120 h), or cisplatin (80 mg/m2) with docetaxel (80 mg/m2), or cisplatin (60 mg/m2) with 5-fluorouracil (600 mg/m2 over 120 h), and docetaxel (60 mg/m2) administered at 3-week intervals for two or three cycles. Concurrent chemotherapy consisted of cisplatin (80 or 100 mg/m2) given in weeks 1, 4, and 7 of radiotherapy, or cisplatin (40 mg/m2) given weekly during radiotherapy. Overall, three well-matched risk groups (low, intermediate, and high risk) were created using propensity score matching, and IC plus CCRT was compared with CCRT in each risk group. Our primary endpoint was distant metastasis-free survival (DMFS). Results: A nomogram for DMFS was established with good prognostic accuracy (C-index, 0.69; 95% confidence interval, 0.64–0.73). The survival curves for low, intermediate, and high-risk groups stratified by the nomogram were significantly different between all three risk groups, with corresponding 5-year DMFS rates of 90.7%, 79.4%, and 64.9%, respectively ( p < 0.001). IC plus CCRT was significantly associated with superior DMFS as compared with CCRT alone (69.5% versus 56.7%, p = 0.004) in the high-risk group. However, no significant difference between IC plus CCRT and CCRT was observed ( p = 0.831 and 0.608, respectively) in the intermediate and low-risk groups. Conclusions: Our findings can help accurately guide the treatment of individual patients with advanced N-stage NPC.

(1) Purpose: This study aims to explore risk-adapted treatment for elderly patients with locoregionally advanced nasopharyngeal carcinoma (LA-NPC) according to their pretreatment risk stratification and the degree of comorbidity. (2) Methods: A total of 583 elderly LA-NPC patients diagnosed from January 2011 to January 2018 are retrospectively studied. A nomogram for disease-free survival (DFS) is constructed based on multivariate Cox regression analysis. The performance of the model is evaluated by using the area under the curve (AUC) of the receiver operating characteristic curve and Harrell concordance index (C-index). Then, the entire cohort is divided into different risk groups according to the nomogram cutoff value determined by X-tile analysis. The degree of comorbidities is assessed by the Charlson Comorbidity Index (CCI). Finally, survival rates are estimated and compared by the Kaplan–Meier method and the log-rank test. (3) Results: A nomogram for DFS is constructed with T/N classification, Epstein-Barr virus DNA and albumin. The nomogram shows well prognostic performance and significantly outperformed the tumor-node-metastasis staging system for estimating DFS (AUC, 0.710 vs. 0.607; C-index, 0.668 vs. 0.585; both p < 0.001). The high-risk group generated by nomogram has significantly poorer survival compared with the low-risk group (3-year DFS, 76.7% vs. 44.6%, p < 0.001). For high-risk patients with fewer comorbidities (CCI = 2), chemotherapy combined with radiotherapy is associated with significantly better survival (p < 0.05) than radiotherapy alone. (4) Conclusion: A prognostic nomogram for DFS is constructed with generating two risk groups. Combining risk stratification and the degree of comorbidities can guide risk-adapted treatment for elderly LA-NPC patients.

Abstract BackgroundThe value of induction chemotherapy (IC) is still controversial for stage T3-4N1 nasopharyngeal carcinoma (NPC) patients receiving concurrent chemoradiotherapy (CCRT). Therefore, we established a nomogram to predict clinical outcome and explore the therapeutic efficiency of IC. MethodsOverall, 699 stage T3-4N1 NPC patients treated with CCRT with or without IC between January 2010 and December 2018 were examined. Overall survival (OS) was regarded the main endpoint. A nomogram was developed including prognostic variables selected by multivariate analysis. The Harrell Concordance Index (C-index), calibration curves, and time-dependent receiver operator characteristic (td-ROC) curves were performed to assess the predictive ability of the nomogram. All patients were divided into high- and low-risk groups based on the optimal cutoff of risk score to investigate the role of IC. Resultshe nomogram yielded C-index of C-index of 0.725 (95% CI: 0.672–0.778) in the training and 0.647 (95% CI: 0.580–0.742) in the validation cohort. Calibration curves for 3- and 5-year OS rate suggested a good association between the nomogram predicted and actual observed probabilities. Td-ROC analysis demonstrated good discriminatory ability. In the high-risk group, no statistically significant difference was observed between patients receiving IC + CCRT and those with CCRT alone. However, in the low-risk group, the applying of IC was associated with worse locoregional recurrence-free survival (LRRFS) and distant metastasis-free survival (DMFS). Conclusionse established and validated a nomogram for LA-NPC patients with N1 disease to predict OS and determine necessity of IC, which has satisfactory prognosis predicting ability and clinical practicability. The use of IC for stage T3-4N1 NPC patients should be considered carefully.

Introduction. Endometrial cancer ranks the third place in prevalence among all cancers in Ukraine. The surgical treatment and subsequent adjuvant treatment is planned according to the patient's risk group. The choice of radiation therapy and the need to add chemotherapy determines the level of recurrence-free survival. Objective. The aim of the study was to analyze the database of treated patients in National Cancer Institute, with I stage endometrial cancer intermediate and high-intermediate group; determination of the most frequent choice of radiation treatment in accordance with the risk group of patients with a hysterectomy with salpingo-oophorectomy for further observation and evaluation of diseasefree survival. Materials and methods. Retrospective was analysed 245 patients with high and intermediate risk groups with stage I endometrial cancer. The exclusion criteria were: low-risk patients, stages II–IV and non-endometrioid histological variant. Results. According to the analysis, there were 122/245 (49.8 %) patients of high risk group, 123/245 (50.2 %) of intermediate risk group. High-risk patients underwent external beam therapy and brychytherapy, supplemented by chemotherapy in 5.8 % of cases (7 patients), brachytherapy with external beam therapy was performed in 58.2 % of cases (71 patients), brachytherapy – in 8.1 % of cases (10 patients), external beam therapy was performed in 27.9 % cases. Intermediate and high-intermediate risk patients were distributed as follows: brachytherapy was performed in 41.5 % of cases (51 patients), brachytherapy with external beam therapy – 54.5 % (67 patients), external beam therapy was performed in 5 patients. Conclusion. Brachytherapy is available for patients with intermediate risk endometrial cancer and external beam therapy with possible addition of brachytherapy is recommended for high-intermediate and high-risk groups, especially in patients with lymphatic vascular involvement. All patients are monitored for further assessment of recurrence-free survival. Key words: endometrial cancer, lymphadenectomy, external beam therapy, chemo- and radiotherapy.

Abstract Background and aims: In this research, we aimed to construct a risk classification model to predict overall survival (OS) and locoregional surgery benefit in colorectal cancer (CRC) patients with distant metastasis.Methods: We selected a cohort consisting of 12741 CRC patients diagnosed with distant metastasis between 2010 and 2014, from the Surveillance, Epidemiology and End Results (SEER) database. Patients were randomly assigned into training group and validation group at the ratio of 2:1. Univariable and multivariable Cox regression models were applied to screen independent prognostic factors. A nomogram was constructed and assessed by the Harrell’s concordance index (C-index) and calibration plots. A novel risk classification model was further established based on the nomogram.Results: Ultimately 12 independent risk factors including race, age, marriage, tumor site, tumor size, grade, T stage, N stage, bone metastasis, brain metastasis, lung metastasis and liver metastasis were identified and adopted in the nomogram. The C-indexes of training and validation groups were 0.77 (95% confidence interval [CI] 0.73-0.81) and 0.75 (95% CI 0.72-0.78), respectively. The risk classification model stratified patients into three risk groups (low-, intermediate- and high-risk) with divergent median OS (low-risk: 36.0 months, 95% CI 34.1-37.9; intermediate-risk: 18.0 months, 95% CI 17.4-18.6; high-risk: 6.0 months, 95% CI 5.3-6.7). Locoregional therapies including surgery and radiotherapy could prognostically benefit patients in the low-risk group (surgery: hazard ratio [HR] 0.59, 95% CI 0.50-0.71; radiotherapy: HR 0.84, 95% CI 0.72-0.98) and intermediate risk group (surgery: HR 0.61, 95% CI 0.54-0.68; radiotherapy: HR 0.86, 95% CI 0.77-0.95), but not in the high-risk group (surgery: HR 1.03, 95% CI 0.82-1.29; radiotherapy: HR 1.03, 95% CI 0.81-1.31). And all risk groups could benefit from systemic therapy (low-risk: HR 0.68, 95% CI 0.58-0.80; intermediate-risk: HR 0.50, 95% CI 0.47-0.54; high-risk: HR 0.46, 95% CI 0.40-0.53).Conclusion: A novel risk classification model predicting prognosis and locoregional surgery benefit of CRC patients with distant metastasis was established and validated. This predictive model could be further utilized by physicians and be of great significance for medical practice.

PURPOSE The treatment of childhood nasopharyngeal carcinoma has been adapted from adult regimens; pediatric-specific studies are limited. The ARAR0331 study sought to evaluate the impact of induction chemotherapy (IC) and concurrent chemoradiotherapy (CCR). PATIENTS AND METHODS Patients with American Joint Committee on Cancer stages IIb to IV were scheduled to receive three cycles of IC with cisplatin and fluorouracil, followed by CCR with three cycles of cisplatin. Patients with complete or partial response to IC received 61.2 Gy to the nasopharynx and neck, and patients with stable disease received 71.2 Gy. RESULTS Between February 2006 and January 2012, 111 patients (75 male) were enrolled. Median age was 15 years, and 46.8% of the patients were African American. After a feasibility analysis, the study was amended to reduce cisplatin to two cycles during CCR. The 5-year event-free survival (EFS) and overall survival estimates were 84.3% and 89.2%, respectively. The 5-year EFS for stages IIb, III, and IV were 100%, 82.8%, and 82.7%, respectively. The 5-year cumulative incidence estimates of local, distant, and combined relapse were 3.7%, 8.7%, and 1.8%, respectively. Patients treated with three versus two CCR cycles of cisplatin had improved 5-year postinduction EFS (90.7% v 81.2%, P = .14). CONCLUSION Patients in ARAR0331 were characterized by advanced disease and by a high proportion of black children and adolescents. Treatment with IC and CRT resulted in excellent outcomes. A radiation dose reduction is possible for patients responding to IC. Although the outcomes are comparable, we observed a trend toward decreased EFS for patients assigned to receive fewer doses of cisplatin during CCR.

Background: The treatment effects of cumulative cisplatin dose (CCD) during radiotherapy (RT) following induction chemotherapy (IC) have not been determined for patients with locoregionally advanced nasopharyngeal carcinoma (NPC). Methods: A total of 3460 patients with locoregionally advanced NPC who were treated with IC plus cisplatin-based concurrent chemoradiotherapy or RT alone were included in this retrospective study. Three CCD groups (0 mg/m2 ⩽ CCD <100 mg/m2, 100 mg/m2 ⩽ CCD <200 mg/m2, CCD ⩾200 mg/m2) were balanced through the inverse probability of treatment weighting based on propensity scores estimated by a general boosted model. The primary endpoint was overall survival (OS); the secondary endpoints were distant metastasis-free survival (DMFS) and locoregional recurrence-free survival (LRFS). Results: CCD ⩾200 mg/m2 and <200 mg/m2 exhibited similar treatment effects for OS and DMFS, and were both superior to CCD <100 mg/m2 for OS and DMFS in patients with stage IVa NPC. The three CCD groups achieved similar treatment effects for patients with stage II–III NPC. After IC, CCD during RT appeared to exert little treatment effect on LRFS. Conclusion: The CCD during RT exerts treatment effects and improves OS by reducing the risk of distant metastasis for patients with stage IVa NPC following IC, and CCD <200 mg/m2 (mainly 160 mg/m2 in this group) is recommended. However, RT alone may be sufficient after IC in patients with stage II–III NPC.

Abstract We introduced a risk-adapted treatment program for non-APL AML in four Swedish health regions. The aim was to optimise treatment results by the use of risk group stratification, mainly based on cytogenetic findings at diagnosis. All patients received induction therapy with idarubicin-cytarabine 3+7 and consolidation cycles containing high-dose cytarabine. Stem cell transplantation was done in CR1 in selected patients, sparing patients with low/intermediate risk of relapse the risks associated with transplantation. 279 patients, 77% of all AML patients 18–60 years (median 51 yrs), in the population were included in the program. Cytogenetics was performed in 98%. Excluding APL, 19 patients had low-risk. The intermediate-risk group consisted of 165 patients, 96 with a normal karyotype. 95 patients were allocated to the high-risk group. 6% died < 30 days after diagnosis. CR rate was 80%. 111 transplants, 78 allogeneic/URD and 33 autologous, were performed in CR1. 40% of all patients were alive after five years. Median overall survival time was 887 days in low-risk, 611 days in intermediate risk, 345 days in high-risk patients. Relapse-free survival times were also significantly (p<0.001) different between the three risk groups. 43% of responding patients were alive in first remission after four years. 4-year relapse-free survival was significantly better for both intermediate risk (67%) and high-risk (41%) with allogeneic/URD transplantation than with autologous transplant or chemotherapy alone. Relapse was observed more often among patients treated with chemotherapy alone (42%, p=0.03) or with autologous transplants (42%, p=0.09) than among patients receiving allogeneic/URD transplants in CR1, 22%. Our results do not support the use of autologous transplantation in AML in first remission.

Abstract Background We aimed to comprehensively investigate the optimal cumulative cisplatin dose during concurrent chemoradiotherapy (CC-CCD) for locoregionally advanced nasopharyngeal carcinoma (CA-LANPC) with different tumor responses after neoadjuvant chemotherapy (NAC). Methods Patients with CA-LANPC who underwent NAC followed by cisplatin-based concurrent chemoradiotherapy were retrospectively analyzed. Evaluation of tumor response in patients was conducted by Response Evaluation Criteria for Solid Tumor (RECIST) 1.1 after two to four cycles NAC. Multivariate Cox proportional hazards models were used for prognosis. Recursive partitioning analysis (RPA) was conducted to classify participates and predict disease-free survival (DFS). Results One hundred and thirty-two patients with favorable response after NAC were included. The median CC-CCD was 163 mg/m2 (IQR, 145–194 mg/m2), and 160 mg/m2 was selected as the cutoff point to group patients into low and high CC-CCD groups (< 160 vs. ≥ 160 mg/m2). There was significant improvement in 5-year DFS (91.2% vs. 72.6%; P = 0.003) for patients receiving high CC-CCD compared to those receiving low CC-CCD. Multivariate analysis revealed that CC-CCD, T stage, and Epstein–Barr virus (EBV) DNA were independent prognostic factors for DFS (P < 0.05 for all). Patients were further categorized into two prognostic groups by RPA: the low-risk group (T1-3 disease with regardless of EBV DNA, and T4 disease with EBV DNA < 4000 copy/mL), and the high-risk group (T4 disease with EBV DNA ≥ 4000 copy/mL). Significant 5-year DFS improvement was observed for the high-risk group (P = 0.004) with high CC-CCD. However, DFS improvement was relatively insignificant in the low-risk group (P = 0.073). Conclusions CC-CCD was a positive prognostic factor for responders after NAC in CA-LANPC. Furthermore, CC-CCD ≥ 160 mg/m2 could significantly improve DFS in the high-risk group with CA-LANPC, but the benefit of high CC-CCD in the low-risk group needs further study.
