Induction immunotherapy plus chemotherapy followed by definitive chemoradiation therapy in locally advanced esophageal squamous cell carcinoma: a propensity-score matched study.

BACKGROUND: For patients with unresectable locally advanced esophageal squamous cell carcinoma (ESCC), concurrent chemoradiotherapy (CCRT) is the current standard treatment; however, the prognosis remains poor. Immunotherapy combined with chemotherapy has demonstrated improved survival outcomes in advanced ESCC. Nevertheless, there is a lack of reports on the role of induction immunotherapy plus chemotherapy prior to CCRT for unresectable locally advanced ESCC. Therefore, this study aimed to evaluate the efficacy and safety of induction immunotherapy plus chemotherapy followed by definitive chemoradiotherapy in patients with unresectable locally advanced ESCC. METHODS: This study retrospectively collected clinical data of patients diagnosed with locally advanced ESCC who were treated with radical CCRT between 2017 and 2021 at our institution. The patients were divided into two groups: an induction immunotherapy plus chemotherapy group (induction IC group) or a CCRT group. To assess progression-free survival (PFS) and overall survival (OS), we employed the Kaplan-Meier method after conducting propensity score matching (PSM). RESULTS: A total of 132 patients with unresectable locally advanced ESCC were included in this study, with 61 (45.26%) patients in the induction IC group and 71 (54.74%) patients in the CCRT group. With a median follow-up of 37.0 months, median PFS and OS were 25.2 and 39.2 months, respectively. The patients in the induction IC group exhibited a significant improvement in PFS and OS in comparison with those in the CCRT group (median PFS: not reached [NR] versus 15.9 months, hazard ratio [HR] 0.526 [95%CI 0.325-0.851], P = 0.0077; median OS: NR versus 25.2 months, HR 0.412 [95%CI 0.236-0.719], P = 0.0012). After PSM (50 pairs), both PFS and OS remained superior in the induction IC group compared to the CCRT group (HR 0.490 [95%CI 0.280-0.858], P = 0.011; HR 0.454 [95%CI 0.246-0.837], P = 0.0093), with 2-year PFS rates of 67.6 and 42.0%, and the 2-year OS rates of 74.6 and 52.0%, respectively. Multivariate analysis revealed that lower tumor stage, concurrent chemotherapy using double agents, and induction immunotherapy plus chemotherapy before CCRT were associated with better prognosis. CONCLUSIONS: Our results showed for the first time that induction immunotherapy plus chemotherapy followed by CCRT for unresectable locally advanced ESCC provided a survival benefit with manageable safety profile. More prospective clinical studies should be warranted.

Clinical Analysis of the Efficacy and Safety of Different Neoadjuvant Strategies in the Treatment of Locally Advanced Rectal Cancer.

OBJECTIVE: In this study, we retrospectively analysed the efficacy and safety of three treatment models, namely, short-course radiotherapy sequential XELOX chemotherapy, neoadjuvant mFOLFOX6 concurrent radiotherapy and long-course concurrent radiotherapy with total mesorectal excision (TME) after treatment of locally advanced rectal cancer with high-risk factors. METHODS: We collected clinical data on 177 patients with locally advanced rectal cancer (cT3-4 and/or cN+) who were treated at the Department of Abdominal Oncology of the Affiliated Cancer Hospital of Guizhou Medical University from December 2017 to December 2022. All patients were associated with 2-3 risk factors [T4b, N2, Extramural Vascular Invasion (EMVI), Mesorectal Fascia (MRF) positivity], positive lateral lymph nodes. Among them, there were 45 cases in the short course radiotherapy sequential XELOX chemotherapy group (RT + XELOX group); 64 cases in the neoadjuvant mFOLFOX6 concurrent radiotherapy group (mFOLFOX6 + CRT group); and 68 cases in the long course concurrent radiotherapy group (CRT group). The RT + XELOX group and mFOLFOX6 + CRT group completed radiotherapy and 4 cycles of neoadjuvant chemotherapy, respectively, and then rested for 1-2 weeks before TME surgery; the CRT group completed concurrent radiotherapy and then rested for 6-8 weeks before TME surgery.Adjuvant chemotherapy was conducted after surgery in each of the three groups: 2 cycles of adjuvant chemotherapy with XELOX regimen in the RT + XELOX group, 4-6 cycles of adjuvant chemotherapy with mFOLFOX6 in the mFOLFOX6 + CRT group, and 8-12 cycles of adjuvant chemotherapy with mFOLFOX6 in the CRT group.The pathological complete response rate (pCR rate), tumour downstage rate, tumour complete resection rate (R0 resection rate), local recurrence rate, distant metastasis rate, overall survival rate, incidence of adverse reactions, surgical complications and completion rate of perioperative systemic chemotherapy were compared among patients in the three groups of cases after TME. RESULTS: The pCR rate (21.95% vs 17.24% vs 5.00%, p = 0.034) and and tumour downstage rate (78.05% vs 68.97% vs 53.33%, p = 0.029) were higher in the RT + XELOX group and mFOLFOX6 + CRT group compared to the CRT group. The RT + XELOX group had a lower 3-year distant metastasis rate (14.63% vs 36.67%, p = 0.048) and improved 3-year overall survival (76.57% vs 48.56%, p < 0.001) compared to the CRT group. There was no significant reduction in the 3-year distant metastasis rate in the mFOLFOX6 + CRT group versus the CRT group (27.59% vs 36.67%, p = 0.719), and the 3-year overall survival was similar (51.23% vs 48.56%, p = 0.35). Multi-logistic regression analysis and stratified analysis showed that patients in the RT + XELOX group and mFOLFOX6 + CRT group were more likely to achieve pCR than the CRT group (RT + XELOX group: OR 7.3, 95% CI [2.6-20.8], p < 0.001; mFOLFOX6 + CRT group OR 2.9, 95% CI [1.1-7.9], p = 0.036). The completion rates of perioperative systemic chemotherapy in the RT + XELOX, mFOLFOX6 + CRT, and CRT groups were 82.93% vs. 84.48% vs. 61.67% (χ2=9.95, p = 0.007), respectively. And there were significant differences in grade 3-4 leukopenia and thrombocytopenia (incidence of leukopenia: 15.50% vs. 7.81% vs. 1.47%, p = 0.045; incidence of thrombocytopenia: 13.33% vs 7.81% vs 1.47%, p = 0.027). There was no significant difference in the incidence of intraoperative and postoperative complications among the three groups (p > 0.05). CONCLUSIONS: RT + XELOX group and mFOLFOX6 + CRT group significantly improved the near-term outcome (e.g., pCR rate) in patients with locally advanced rectal cancer with high-risk factors compared with CRT group. The RT + XELOX group also reduced the 3-year distant metastasis rate, increased the 3-year overall survival rate, and did not increase the incidence of perioperative surgical complications. It provides an effective means for the comprehensive treatment of locally advanced rectal cancer and has important clinical guidance and application value.

Prognostic significance of platelet­to­albumin ratio in patients with nasopharyngeal carcinoma receiving concurrent chemoradiotherapy: a retrospective study of 858 cases.

BACKGROUND: Despite evidence supporting the high correlation of the novel platelet-to-albumin ratio (PAR) with survival in diverse malignancies, its prognostic relevance in nasopharyngeal carcinoma (NPC) remains underexplored. This study aimed to examine the link between PAR and overall survival (OS) in NPC and to establish a predictive model based on this biomarker. METHODS: We retrospectively assembled a cohort consisting of 858 NPC patients who underwent concurrent chemoradiotherapy (CCRT). Utilizing the maximally selected log-rank method, we ascertained the optimal cut-off point for the PAR. Subsequently, univariate and multivariate Cox proportional hazards models were employed to discern factors significantly associated with OS and to construct a predictive nomogram. Further, we subjected the nomogram's predictive accuracy to rigorous independent validation. RESULTS: The discriminative optimal PAR threshold was determined to be 4.47, effectively stratifying NPC patients into two prognostically distinct subgroups (hazard ratio [HR] = 0.53; 95% confidence interval [CI]: 0.28-0.98, P = 0.042). A predictive nomogram was formulated using the results from multivariate analysis, which revealed age greater than 45 years, T stage, N stage, and PAR score as independent predictors of OS. The nomogram demonstrated a commendable predictive capability for OS, with a C-index of 0.69 (95% CI: 0.64-0.75), surpassing the performance of the conventional staging system, which had a C-index of 0.56 (95% CI: 0.65-0.74). CONCLUSIONS: In the context of NPC patients undergoing CCRT, the novel nutritional-inflammatory biomarker PAR emerges as a promising, cost-efficient, easily accessible, non-invasive, and potentially valuable predictor of prognosis. The predictive efficacy of the nomogram incorporating the PAR score exceeded that of the conventional staging approach, thereby indicating its potential as an enhanced prognostic tool in this clinical setting.

The addition of nimotuzumab during concurrent chemoradiotherapy improved survival outcomes in locally advanced nasopharyngeal carcinoma patients with optimal response to induction chemotherapy.

OBJECTIVE: To investigate the impact of response to induction chemotherapy (IC) on survival outcomes in patients with locally advanced nasopharyngeal carcinoma (LANPC) and evaluate the efficacy of adding nimotuzumab to concurrent chemoradiotherapy (CCRT) based on different responses to IC. METHODS: We retrospectively included patients with stage III-IVA NPC who underwent IC with and without nimotuzumab during CCRT. Statistical analysis included the chi-square test, propensity score matching, Kaplan-Meier survival analysis, and Cox proportional hazards model. RESULTS: Among 383 identified patients, 216 (56.4%) received nimotuzumab during CCRT, while 167 (43.6%) did not. Following IC, 269 (70.2%) patients showed a complete response (CR) or partial response (PR), and 114 (29.8%) had stable disease (SD) or progressive disease (PD). The response to IC independently influenced disease-free survival (DFS) and overall survival (OS). Patients achieving CR/PR demonstrated significantly higher 3-year DFS (80.3% vs. 70.6%, P = 0.031) and OS (90.9% vs. 83.2%, P = 0.038) than those with SD/PD. The addition of nimotuzumab during CCRT significantly improved DFS (P = 0.006) and OS (P = 0.037) for CR/PR patients but not for those with SD/PD. CONCLUSIONS: This study emphasizes the importance of IC response in LANPC and highlights the potential benefits of nimotuzumab during CCRT for improving survival outcomes in CR/PR patients. Tailored treatment approaches for SD/PD patients warrant further investigation.

Consolidation chemotherapy after definitive concurrent chemoradiotherapy in patients with inoperable esophageal squamous cell carcinoma: a multicenter non-inferiority phase III randomized clinical trial.

BACKGROUND: Definitive concurrent chemoradiotherapy (dCCRT) is the gold standard for the treatment of locally advanced esophageal squamous cell carcinoma (ESCC). However, the potential benefits of consolidation chemotherapy after dCCRT in patients with esophageal cancer remain debatable. Prospective randomized controlled trials comparing the outcomes of dCCRT with or without consolidation chemotherapy in patients with ESCC are lacking. In this study, we aim to generate evidence regarding consolidation chemotherapy efficacy in patients with locally advanced, inoperable ESCC. METHODS: This is a multicenter, prospective, open-label, phase-III randomized controlled trial comparing non-inferiority of dCCRT alone to consolidation chemotherapy following dCCRT. In total, 600 patients will be enrolled and randomly assigned in a 1:1 ratio to receive either consolidation chemotherapy after dCCRT (Arm A) or dCCRT alone (Arm B). Overall survival will be the primary endpoint, whereas progression-free survival, locoregional progression-free survival, distant metastasis-free survival, and treatment-related toxicity will be the secondary endpoints. DISCUSSION: This study aid in further understanding the effects of consolidation chemotherapy after dCCRT in patients with locally advanced, inoperable ESCC. TRIAL REGISTRATION: ChiCTR1800017646.

The prognostic role of pre-treatment neutrophil to lymphocyte ratio and platelet to lymphocyte ratio in esophageal squamous cell carcinoma treated with concurrent chemoradiotherapy.

PURPOSE: In this study, we retrospectively investigated the prognostic role of pre-treatment neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) in esophageal squamous cell carcinoma patients (ESCC) treated with concurrent chemo-radiotherapy (CCRT). METHODS: We retrospectively analyzed the records of 338 patients with pathologically diagnosed esophageal squamous cell carcinoma that underwent concurrent chemo-radiotherapy from January 2013 to December 2017. Univariate and multivariate analyses were used to identify prognostic factors for progression free survival (PFS) and overall survival (OS). RESULTS: The result showed that the thresholds for NLR and PLR were 2.47 and 136.0 by receiver operating characteristic curve. High NLR and PLR were both associated with tumor length (P < 0.05). High NLR and PLR were significantly associated with poor PFS and OS. Multivariate analyses identified NLR, PLR and TNM stage were independent risk factors for PFS and OS. CONCLUSIONS: We show that the pre-treatment NLR and PLR may serve as prognostic indicators for esophageal squamous cell carcinoma treated with concurrent chemo-radiotherapy.

Peripheral hemoglobin to albumin ratio predicts prognosis in patients with nasopharyngeal carcinoma underwent concurrent chemoradiotherapy.

BACKGROUND: Recently, the hemoglobin to albumin ratio (HAR) has been shown to be closely associated with the survival of certain malignancies. However, its prognostic value in nasopharyngeal carcinoma (NPC) remained to be elucidated. Herein, we aimed to explore the correlation between HAR and overall survival (OS) in NPC patients treated with concurrent chemoradiotherapy (CCRT). METHODS: This retrospective study included a total of 858 patients with NPC receiving CCRT between January 2010 and December 2014 in Sun Yat-sen University Cancer Center. We randomly divided them into the training cohort (N = 602) and the validation cohort (N = 206). We performed univariate and multivariate Cox regression analyses to identify variables associated with OS, based on which, a predictive nomogram was constructed and assessed. RESULTS: In both the training and validation cohorts, patients were classified into low- and high-HAR groups according to the cutoff value determined by the maximally selected rank statistics. This HAR cutoff value effectively divided patients into two distinct prognostic groups with significant differences. Multivariable Cox analysis revealed that higher T-stage, N-stage, and HAR values were significantly related to poorer prognosis in NPC patients and served as independent prognostic factors for NPC. Based on these, a predictive model was constructed and graphically presented as a nomogram, whose predictive performance is satisfactory with a C-index of 0.744 [95%CI: 0.679-0.809] and superior to traditional TNM staging system [C-index = 0.609, 95%CI: 0.448-0.770]. CONCLUSION: The HAR value was an independent predictor for NPC patients treated with CCRT, the predictive model based on HAR with superior predictive performance than traditional TNM staging system might improve individualized survival predictions.

Endostar acts as a pneumonitis protectant in patients with locally advanced non-small cell lung cancer receiving concurrent chemoradiotherapy.

BACKGROUND: CCRT is presently the standard treatment for LA-NSCLC. RP is one of the main obstacles to the completion of thoracic radiation therapy, resulting in limited survival benefits in NSCLC patients. This research aims to explore the role of Endostar in the occurrence of grade≥2 RP and clinical curative effect in LA-NSCLC patients. METHODS: This study retrospectively analyzed 122 patients with stage III NSCLC who received CCRT from December 2008 to December 2017, or Endostar intravenous drip concurrently with chemoradiotherapy (Endostar + CCRT group). Standard toxicity of the pneumonitis endpoint was also collected by CTCAE V5.0. We further summarized other available studies on the role of Endostar in the prognosis of NSCLC patients and the incidence of RP. RESULTS: There were 76 cases in the CCRT group and 46 cases in the CCRT+ Endostar group. In the CCRT+ Endostar group, the occurrence of grade ≥2 RP in patients with V20Gy ≥25% was significantly higher than that in patients with V20Gy < 25% (p = 0.001). In the cohorts with V20Gy < 25%, 0 cases of 29 patients treated with Endostar developed grade ≥2 RP was lower than in the CCRT group (p = 0.026). The re-analysis of data from other available studies indicated that Endostar plus CCRT could be more efficient and safely in the occurrence of grade≥2 RP with LA-NSCLC. CONCLUSIONS: When receiving CCRT for LA-NSCLC patients, simultaneous combination of Endostar is recommended to enhance clinical benefit and reduce pulmonary toxicity.

Neoadjuvant chemotherapy followed by surgery versus concurrent chemoradiotherapy in patients with stage IIB cervical squamous cell carcinoma: a retrospective cohort study.

PURPOSE: This study aims to compare treatment outcomes between neoadjuvant chemotherapy (NACT) followed by surgery and concurrent chemoradiotherapy (CCRT) in patients with stage IIB cervical squamous cell carcinoma (CSCC). MATERIALS AND METHODS: We conducted a retrospective cohort study involving patients with stage IIB CSCC treated at Guangxi Medical University Cancer Hospital between June 2012 and June 2019. We compared overall survival (OS), locoregional-free survival (LRFS), and distant metastasis-free survival (DMFS) between the NACT + surgery and CCRT groups. RESULTS: A total of 257 patients were enrolled: 165 underwent NACT + surgery and 92 received CCRT. Before propensity score matching, the NACT + surgery group exhibited lower 5-year OS (68.2% vs. 85.6%; hazard ratio [HR] = 2.50, 95% confidence interval [CI]: 1.26-4.96; P = 0.009), LRFS (85.2% vs. 96.9%; HR = 5.88, 95% CI: 1.33-25.94; P = 0.019), and DMFS (81.9% vs. 97.4%; HR = 6.65, 95% CI: 1.51-29.23; P = 0.012) compared to the CCRT group. After propensity score matching, OS, LRFS, and DMFS remained worse in the NACT + surgery group compared to the CCRT group. CONCLUSION: NACT followed by surgery is associated with decreased OS, LRFS, and DMFS compared to CCRT among patients with stage IIB CSCC.

Efficacy and safety of different chemotherapy regimens concurrent with radiotherapy in the treatment of locally advanced cervical cancer.

BACKGROUND: Evaluate the efficacy and safety of different chemotherapy regimens concurrent with radiotherapy in treating locally advanced cervical cancer (LACC). METHODS: Retrospective data was collected from LACC patients who were treated at our institution. These patients were categorized into three groups: the single-agent cisplatin (DDP) chemoradiotherapy group, the paclitaxel plus cisplatin (TP) chemoradiotherapy group, and the nanoparticle albumin-bound (nab-) paclitaxel combined with cisplatin (nPP) chemoradiotherapy group. The primary endpoints were overall survival (OS) and progression-free survival (PFS) and the secondary endpoints were objective response rate (ORR) and incidence of adverse events (AEs). RESULTS: A total of 124 patients were enrolled (32 in the DDP group, 41 in the TP group, and 51 in the nPP group). There were differences in OS (P = 0.041, HR 0.527, 95% CI 0.314-0.884) and PFS (P = 0.003, HR 0.517, 95% CI 0.343-0.779) between the three groups. Notably, the 2-year OS rate was significantly higher in the nPP group compared to the DDP group (92.2% vs. 85.4%, P = 0.012). The 2-year PFS rates showed a marked increase in the TP group (78.0% vs. 59.4%, P = 0.048) and the nPP group (88.2% vs. 59.4%, P = 0.001) relative to the DPP group, with multiple comparisons indicating that the 2-year PFS rate was significantly superior in the nPP group versus the DDP group (88.2% vs. 59.4%, P = 0.001). Moreover, the ORR was also significantly higher in the nPP group than in the DDP group (P = 0.013); and no statistically significant differences were found in the incidence of AEs among the groups (P > 0.05). CONCLUSIONS: In LACC treatment, the two cisplatin-based doublet chemotherapy regimens are associated with better outcomes, with the nab-paclitaxel plus cisplatin regimen showing better efficacy than the paclitaxel plus cisplatin regimen. Furthermore, the AEs associated with these regimens were deemed tolerable. These findings could provide a reference for the clinical treatment of LACC. However, further prospective studies are needed to verify it.

PD-1 inhibitor plus concurrent chemoradiotherapy for high-risk locally advanced cervical cancer.

Aim: The prognosis of high-risk, locally advanced cervical cancer (LACC) remains poor following concurrent chemoradiotherapy (CCRT). We investigated whether the effect of CCRT can be enhanced by programmed cell death protein 1 (PD-1) inhibitor. Methods: A retrospective cohort study was conducted to compare the efficacy and safety of CCRT group (n = 82) and PD-1 inhibitor plus CCRT group (n = 70). Results: Compared with the CCRT group, the PD-1 inhibitor plus CCRT group had significantly higher objective response rate, median progression-free survival, leukopenia and fatigue. The addition of PD-1 inhibitor to CCRT showed a favorable trend in overall survival without statistical significance. Conclusion: PD-1 inhibitor plus CCRT presented a significant survival benefit and a manageable safety profile in high-risk LACC.

Frailty is an independent factor for health-related quality of life in patients with head and neck cancer receiving definitive concurrent chemoradiotherapy.

PURPOSE: Health-related quality of life (HRQoL) is associated with treatment-related complications and poor survival in patients with head and neck cancer (HNC). We investigated the effects of frailty on HRQoL in patients with HNC receiving definitive concurrent chemoradiotherapy (CCRT). METHODS: A total of 461 consecutive patients with locally advanced HNC who received CCRT between 2017 and 2018 at three medical centers in Taiwan were included. Frailty and HRQoL were assessed using the Comprehensive Geriatric Assessment and QLQ-H&N35 before CCRT. The sum score was calculated based on the first 30 questions of QLQ-H&N35. Multivariate analysis was performed to evaluate the impact of frailty on HRQoL. RESULTS: The overall sum score was 39 (34-49). The sum scores of patients with impairments in 0, 1, 2, 3, and ≥ 4 frailty domains were 34 (32-38), 40 (34-47), 46 (36-55), 48 (41-64), and 56 (50-60), respectively. Patients with impairments in more frailty domains had a higher symptom burden (p for trend < 0.001). Frail patients tended to experience symptoms across all QLQ-H&N35 subscales. Sex, body mass index, tumor type, tumor stage, Eastern Cooperative Oncology Group performance status, and frailty were determinants of HRQoL in the univariate analysis. Frailty was an independent determinant of HRQoL in the multivariate analysis. CONCLUSION: Routine frailty assessment may serve as a surrogate for the selection of patients with HNC with poor HRQoL before CCRT. Further studies are needed to determine whether appropriate interventions in frail patients would improve their HRQoL during CCRT.

Multicenter prospective phase II trial of concurrent chemoradiotherapy with weekly low-dose carboplatin for cisplatin-ineligible patients with advanced head and neck squamous cell carcinoma.

BACKGROUND: The optimal chemotherapy regimen in concurrent chemoradiotherapy (CCRT) for cisplatin-ineligible head and neck squamous cell carcinoma (HNSCC) has not been established. We aimed to evaluate the feasibility, efficacy, and safety of CCRT with weekly low-dose carboplatin for the treatment of advanced HNSCC in patients who are cisplatin-ineligible. METHODS: This prospective phase II study enrolled adult patients (age ≥ 20 years) with HNSCC receiving whole-neck irradiation including bilateral levels II-IV and who were aged (≥ 75-year-old patients with 40 mL/min estimated glomerular filtration rate [eGFR] or better) or had renal dysfunction (< 75-year-old patients with 30-60 mL/min eGFR). Carboplatin was administered weekly (area under the plasma concentration-time curve = 2.0) for up to seven cycles during concurrent radiotherapy (70 Gy/35 Fr). The primary endpoint was the completion rate of CCRT. Secondary endpoints included overall response rate and incidence of adverse events. RESULTS: Among the 30 patients enrolled, 28 were men. The median age was 73.5 years. Seventeen patients were < 75 years whereas 13 were ≥ 75 years old. The completion rate of CCRT was 90%. The overall response rate was 90%. Grade 3 adverse events that occurred in 10% or more patients were oral/pharyngeal mucositis (47%), leukocytopenia (20%), and neutropenia (10%). Grade 4 adverse events occurred in one patient (elevation of alanine aminotransferase level). No treatment-related deaths occurred. CONCLUSION: CCRT with weekly low-dose carboplatin is a promising treatment option, with favorable feasibility, efficacy, and acceptable toxicity, for patients who are cisplatin-ineligible with advanced HNSCC. CLINICAL TRIAL REGISTRATION NUMBER: jRCTs031190028.

Usefulness of pre- and post-treatment volumetric PET/CT parameters in predicting prognosis and evaluating recurrence for chemoradiotherapy-treated hypopharyngeal cancer.

OBJECTIVE: To investigate the usefulness of pre- and post-treatment metabolic tumor volume (MTV) obtained from positron emission tomography (PET) in predicting prognosis and evaluating recurrence in patients with hypopharyngeal cancer (HPC). MATERIALS AND METHODS: Forty-three consecutive HPC patients treated with chemoradiotherapy were retrospectively analyzed. Maximum standard uptake value (SUVmax) and MTV of tumor (T) and lymph node (N) were analyzed. RESULTS: On multivariate analysis using pre-treatment parameters, MTV-T (p = 0.049) and MTV-TN (p = 0.043) were significantly associated with local control (LC), and MTV-N (p = 0.049) was significantly associated with disease-specific survival (DSS). Post-treatment MTV-TN was also significantly associated with prognosis (p < 0.001 in LC; p = 0.002 in DSS) and recurrence (area under curve 0.95). Neither pre- nor post-treatment SUVmax was significantly associated with prognosis. CONCLUSION: Pre- and post-treatment MTV appears useful for predicting prognosis and evaluating recurrence.

Impact of pretreatment quality of life on tolerance and survival outcome in head and neck cancer patients undergoing definitive CCRT.

BACKGROUND: Health-related quality of life (HRQoL) is a predictor of treatment outcomes in cancer patients. This study aimed to evaluate the effect of pretreatment HRQoL on treatment tolerance and survival outcomes in patients with HNC planned for concurrent chemoradiotherapy (CCRT) in Taiwan. METHODS: This study included 461 patients with HNC planned for definitive CCRT at three medical centers in Taiwan between August 2017 and December 2018. HRQoL was assessed using the QLQ-HN35 one week before the initiation of CCRT. Patients were grouped based on the sum scores of QLQ-HN35 (

Prediction of outcomes after chemoradiotherapy for cervical cancer by neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio.

BACKGROUND: Cervical cancer ranks as the second most fatal tumour globally among females. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been widely applied to the diagnosis of cancers. METHODS: The clinicopathologic data of 180 patients with stage IB2-IIB cervical cancer who underwent radical concurrent chemoradiotherapy from January 2018 to December 2019 were retrospectively analysed. Receiver operating characteristic (ROC) curves were plotted to analyse the optimal cut-off values of NLR and PLR for predicting the therapeutic effects of concurrent chemoradiotherapy. The associations of PLR and other clinicopathological factors with 1-year survival rates were explored through univariate analysis and multivariate Cox regression analysis, respectively. RESULTS: NLR was significantly associated with the therapeutic effects of neoadjuvant therapy, with the optimal cut-off value of 2.89, area under the ROC curve (AUC) of 0.848 (95% confidence interval [CI]: 0.712-0.896), sensitivity of 0.892 (95% CI: 0.856-0.923) and specificity of 0.564 (95% CI: 0.512-0.592). PLR had a significant association with the therapeutic effects of neoadjuvant therapy, with the optimal cut-off value of 134.27, AUC of 0.766 (95% CI: 0.724-0.861), sensitivity of 0.874 (95% CI: 0.843-0.905) and specificity of 0.534 (95% CI: 0.512-0.556). Lymphatic metastasis ([95% CI: 1.435-5.461], [95% CI: 1.336-4.281], depth of invasion ([95% CI: 1.281-3.546], [95% CI: 1.183-3.359]) and tumour size ([95% CI: 1.129-3.451], [95% CI: 1.129-3.451]) were independent factors influencing the overall survival and disease-free survival (DFS) of patients with cervical cancer. NLR (95%CI: 1.256-4.039) and PLR (95%CI:1.281-3.546) were also independent factors affecting DFS. CONCLUSION: NLR and PLR in the peripheral blood before treatment may predict DFS of patients with stage IB2-IIB cervical cancer.

The clinicopathologic data of 180 patients with stage IB2-IIB cervical cancer who underwent radical concurrent chemoradiotherapy were retrospectively analysed. Receiver operating characteristic curves showed that neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were significantly associated with the therapeutic effects of neoadjuvant therapy. Univariate and multivariate regression analysis revealed that lymphatic metastasis, depth of invasion and tumour size were independent factors influencing the overall survival and disease-free survival (DFS) of patients with cervical cancer. NLR and PLR in the peripheral blood before treatment may predict the DFS of patients with stage IB2-IIB cervical cancer.

Comparative efficacy and safety of Chinese medicine injections as an adjunctive therapy for cervical cancer in Chinese patients: a network meta-analysis.

CONTEXT: Chinese medicine injections (CMIs) are widely used as adjuvant therapy for cervical cancer in China. However, the effectiveness of different types of CMIs remains uncertain. OBJECTIVE: To assess the effectiveness and safety of CMIs when used in conjunction with radiotherapy (RT) or concurrent chemoradiotherapy (CCRT), particularly in combination with cisplatin (DDP), docetaxel plus cisplatin (DP), and paclitaxel plus cisplatin (TP). MATERIALS AND METHODS: Randomized controlled trials (RCTs) were searched in databases including CNKI, WanFang, VIP, SinoMed, PubMed, Cochrane Library, Embase, and Web of Science from inception to September 2023. We calculated the risk ratio with a 95% confidence interval and the surface under the cumulative ranking area curve (SUCRA) for the clinical efficacy rate (CER), the efficacy rate by Karnofsky Performance Status (KPS), and the rates of leukopenia reduction (LRR) and gastrointestinal reactions (GRR). RESULTS: Forty-seven RCTs were included, including nine CMI types: Aidi, Fufangkushen, Huangqi, Kangai (KA), Kanglaite (KLT), Renshenduotang, Shenqifuzheng (SQFZ), Shenmai (SM), and Yadanzi. KLT and KA were likely optimal choices with radiotherapy for CER and KPS, respectively. KA and KLT were optimal choices with RT + DDP for CER and GRR, respectively. KLT was the likely optimal choice with RT + DP for CER and KA for both KPS and GRR. SM and SQFZ were the likely optimal choices with RT + TP for CER and LRR, respectively. CONCLUSIONS: The optimal recommendation depends on whether CMIs are used with radiotherapy or concurrent chemoradiotherapy. More high-quality RCTs are needed to confirm further and update the existing evidence.

Persisting Gaps in Optimal Care of Stage III Non-small Cell Lung Cancer: An Australian Patterns of Care Analysis.

BACKGROUND: Wide variation exists globally in the treatment and outcomes of stage III patients with non-small cell lung cancer (NSCLC). We conducted an up-to-date patterns of care analysis in the state of Victoria, Australia, with a particular focus on the proportion of patients receiving treatment with radical intent, treatment trends over time, and survival. MATERIALS AND METHODS: Stage III patients with NSCLC were identified in the Victorian Lung Cancer Registry and categorized by treatment received and treatment intent. Logistic regression was used to explore factors predictive of receipt of radical treatment and the treatment trends over time. Cox regression was used to explore variables associated with overall survival (OS). Covariates evaluated included age, sex, ECOG performance status, smoking status, year of diagnosis, Australian born, Aboriginal or Torres Strait Islander status, socioeconomic status, rurality, public/private status of notifying institution, and multidisciplinary meeting discussion. RESULTS: A total of 1396 patients were diagnosed between 2012 and 2019 and received treatment with radical intent 67%, palliative intent 23%, unknown intent 5% and no treatment 5%. Radical intent treatment was less likely if patients were >75 years, ECOG ≥1, had T3-4 or N3 disease or resided rurally. Surgery use decreased over time, while concurrent chemoradiotherapy and immunotherapy use increased. Median OS was 38.0, 11.1, and 4.4 months following radical treatment, palliative treatment or no treatment, respectively. CONCLUSION: Almost a third of stage III patients with NSCLC still do not receive radical treatment. Strategies to facilitate radical treatment and better support decision making between increasing multimodality options are required.

Utility of pre-chemoradiotherapy Pan-Immune-Inflammation-Value for predicting the osteoradionecrosis rates in locally advanced nasopharyngeal cancers.

PURPOSE: The aim of this retrospective study was to explore whether pretreatment Pan-Immune-Inflammation-Value (PIV) measurements might predict the risk of mandibular osteoradionecrosis (ORN) in patients receiving concurrent chemoradiotherapy (CCRT) for locally advanced nasopharyngeal cancer (LA-NPC). METHODS: The platelet, monocyte, neutrophil, and lymphocyte counts acquired on the first day of CCRT were used to compute pretreatment PIV levels: PIV = (Plateletsâ€¯× Monocytesâ€¯× Neutrophils) ÷ Lymphocytes. Receiver operating characteristic curve analysis was used to determine the association between ORN rates and PIV levels. Spearman correlation analysis was used to examine the probable intergroup correlations. The potential link between the pretreatment PIV levels and the post-treatment ORN rates was determined as the primary objective. RESULTS: 21 (10.0%) of 210 eligible patients were diagnosed with ORN. The optimal pre-CCRT PIV cutoff was 833, which separated patients into two PIV groups with divergent ORN prevalence estimates: Group 1: PIV < 833 (N = 153), and Group 2: PIV ≥ 833 (N = 57). The comparison analysis found that the PIV ≥ 833 cohort had significantly higher ORN rates than the PIV < 833 cohort (29.8% vs. 2.6%; P < 0.001). Other characteristics linked to significantly higher ORN rates were the patient's continuing smoking, the use of the Three-dimensional conformal radiation therapy technique, the mean mandibular dose of ≥ 58.1 Gy, the number of tooth extractions before CCRT ≥ 4, and the presence of tooth extractions after CCRT. The independent importance of all factors on higher ORN occurrence rates were retained in multivariate analysis (P < 0.05). CONCLUSIONS: Our findings revealed a strong link between aggravated inflammatory response and ORN genesis, with high pretreatment PIV levels related to significantly higher ORN rates.

Impact of comorbidity scores and lifestyle factors in curative radiotherapy in laryngeal cancer.

PURPOSE: The principal goal of treatment of laryngeal cancer is to eliminate a tumour while preserving laryngeal function with radio(chemo)therapy being the mainstay of treatment. The aim of this report is to present the influence of comorbidities and lifestyle factors on treatment outcomes in our cohort of patients. METHODS: During the period 2009-2018, curative radio(chemo)therapy for laryngeal cancer was performed on 189 patients. RESULTS: The median OS was 50.8 months, with a mean PFS of 96.5 months, mean LC of 101.4 months and a median follow-up of 38.1 months. Acute and late treatment toxicity grade 3-4 was observed in 39.2% patients and 10.1% patients, respectively. A significant effect on overall survival was confirmed for the baseline PS (performance status), severity of weight loss, baseline haemoglobin values, history of alcohol abuse, marital status and comorbidities according to the Charlson Comorbidity Index, as well as the ACE-27 and ASA scores. CONCLUSIONS: In our cohort of patients treated with radio(chemo)therapy for laryngeal cancer, we found good therapeutic results and an acceptable side-effect profile. Statistically significant predictors of overall survival were the baseline PS, weight loss, anaemia, associated comorbidities, history of alcohol abuse and marital status.
