Efficacy and safety of concurrent chemoradiotherapy in ECOG 2 patients with locally advanced non-small-cell lung cancer: a subgroup analysis of a randomized phase III trial.

ABSTRACT: There is no consensus on the therapeutic approach to ECOG 2 patients with locally advanced non-small-cell lung cancer (LA-NSCLC), despite the sizable percentage of these patients in clinical practice. This study focused on the efficacy, toxicity and the optimal chemotherapy regimen of CCRT in ECOG 2 patients in a phase III trial. Patients capable of all self-care with bed rest for less than 50% of daytime were classified as ECOG 2 subgroup. A subgroup analysis was performed for ECOG 2 patients recruited in the phase III trial receiving concurrent EP (etoposide + cisplatin)/PC (paclitaxel + carboplatin) chemotherapy with intensity-modulated radiation therapy (IMRT) or three-dimensional conformal external beam radiation therapy (3D-CRT). A total of 71 ECOG 2 patients were enrolled into the study. Forty-six (64.8%) patients were treated with IMRT technique. The median overall survival (OS) and progression free survival (PFS) for ECOG 2 patients were 16.4?months and 9?months, respectively. No difference was observed in treatment compliance and toxicities between ECOG 2 patients and ECOG 0-1 patients. Within the ECOG 2 group (31 in the EP arm and 40 in the PC arm), median OS and 3-year OS were 15.7?months and 37.5% for the EP arm, and 16.8?months and 7.5% for the PC arm, respectively (p?=?0.243). The incidence of grade???3 radiation pneumonitis was higher in the PC arm (17.5% vs. 0.0%, p?=?0.014) with 5 radiation pneumonitis related deaths, while the incidence of grade 3 esophagitis was numerically higher in the EP arm (25.8% vs. 10.0%, p?=?0.078). CCRT provided ECOG 2 patients promising outcome with acceptable toxicities. EP might be superior to PC in terms of safety profile in the setting of CCRT for ECOG 2 patients. Prospective randomized studies based on IMRT technique are warranted to validate our findings. ClinicalTrials.gov registration number: NCT01494558. (Registered 19 December 2011).

Project description:BackgroundConcurrent chemoradiotherapy is the standard of care for locally advanced cervical cancer. Concurrent chemoradiotherapy with programmed blockade of the cell death-1/programmed cell death-ligand 1 pathway may promote a more immunogenic environment through increased phagocytosis, cell death, and antigen presentation, leading to enhanced immune-mediated tumor surveillance.Primary objectiveThe CALLA trial is designed to determine the efficacy and safety of the programmed cell death-ligand 1 blocking antibody, durvalumab, with and following concurrent chemoradiotherapy versus concurrent chemoradiotherapy alone in women with locally advanced cervical cancer.Study hypothesisDurvalumab concurrent with and following concurrent chemoradiotherapy will improve progression-free survival in patients with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB2 to IVA cervical cancer compared with concurrent chemoradiotherapy alone.Trial designCALLA is a phase III, randomized, multicenter, international, double-blind, placebo-controlled study. Patients will be randomized 1:1 to receive either durvalumab (1500 mg intravenously (IV)) or placebo every 4 weeks for 24 cycles. All patients will receive external beam radiotherapy with cisplatin (40 mg/m2) IV or carboplatin (area under the curve 2) IV once a week for 5 weeks, followed by image-guided brachytherapy.Major inclusion/exclusion criteriaThe study will enroll immunotherapy-naïve adult patients with histologically confirmed cervical adenocarcinoma, cervical squamous, or adenosquamous carcinoma FIGO 2009 stages IB2-IIB node positive and stage IIIA-IVA with any node stage. Patients will have had no prior definitive surgical, radiation, or systemic therapy for cervical cancer.Primary endpointThe primary endpoint is progression-free survival (assessed by the investigator according to Response Evaluation Criteria in Solid Tumors v1.1, histopathological confirmation of local tumor progression or death).Sample sizeApproximately 714 patients will be randomized 1:1 to receive either durvalumab + concurrent chemoradiotherapy or placebo + concurrent chemoradiotherapy.Estimated dates for completing accrual and presenting resultsPatient enrollment is continuing globally with an estimated completion date of April 2024.Trial registrationNCT03830866.

Project description:PurposeInduction chemotherapy plus concurrent chemoradiotherapy and concurrent chemoradiotherapy alone are both standard treatment regimens for managing locally advanced nasopharyngeal carcinoma. However, the results of comparisons between them in clinical trials vary. Therefore, we designed this meta-analysis to illustrate their advantages and disadvantages in patients with locally advanced nasopharyngeal carcinoma.MethodsWe thoroughly searched the PubMed, EMBASE, and Cochrane Library databases and then merged the effect indicators of hazard ratios and risk ratios using RevMan 5.1.ResultsSeven randomized controlled trials totaling 2,319 patients were included in our research. The synthesized results showed that induction chemotherapy plus concurrent chemoradiotherapy improved overall survival (HR = 0.75, 95% CI: 0.63-0.89, P = 0.001), progression-free survival (HR = 0.69, 95% CI: 0.60-0.80, P < 0.001), distant metastasis-free survival (HR = 0.65, 95% CI: 0.53-0.80, P < 0.001) and locoregional recurrence-free survival (HR = 0.68 95%, CI: 0.54-0.86, P = 0.001) versus concurrent chemoradiotherapy alone. It also increased the risk of anemia, thrombocytopenia, and neutropenia during concurrent chemoradiotherapy. However, the incidence of leukopenia and mucositis was similar in induction chemotherapy and induction chemotherapy plus concurrent chemoradiotherapy. Furthermore, the subgroup analysis showed better survival outcomes with induction chemotherapy plus concurrent chemoradiotherapy than with concurrent chemoradiotherapy alone in the triweekly cisplatin subgroup (all P < 0.01), whereas induction chemotherapy plus concurrent chemoradiotherapy could only improve progression-free survival and locoregional recurrence-free survival in the weekly cisplatin subgroup (HR = 0.78, P = 0.02; and HR = 0.66, P = 0.03, respectively).ConclusionsInduction chemotherapy plus concurrent chemoradiotherapy improved survival outcomes in patients with locally advanced nasopharyngeal carcinoma versus concurrent chemoradiotherapy. For the weekly cisplatin regimen subgroup, it did not improve remote control or overall survival versus concurrent chemoradiotherapy alone, warranting further clarification.

Project description:BackgroundThis study aims to investigate the efficacy and safety of postoperative intensity-modulated radiotherapy (IMRT) covering partial regional lymph node areas combined with chemotherapy for locally advanced thoracic esophageal squamous cell carcinoma patients.MethodsThis was a single-center, single-arm phase II clinical trial that began in 2014. Patients who underwent radical transthoracic resection within 3 months and were histologically confirmed esophageal squamous cell carcinoma (pT3-4 or N+, M0 determined according to AJCC Guidelines, Edition 7) were recruited. Postoperative radiotherapy was performed with a total dose of 50.4Gy in 28 fractions using IMRT. Clinical target volumes (CTVs) included tumor bed, anastomosis, bilateral supraclavicular region, and superior mediastinal lymph nodes. Synchronous chemotherapy for 2 cycles (paclitaxel 150mg/m2, day1; Cisplatin 25mg/m2, day1-3; every 4 weeks), followed by 2 cycles of consolidation chemotherapy with the same regimen. The primary endpoint was the 2-year local control rate, and the secondary endpoints were overall survival (OS) and adverse events (AEs).ResultsA total of 75 eligible patients were included from 2014 to 2017. The 2-year LRFS rate, as the primary endpoint, was 73.3%. The 1-year and 3-year OS rates were 88.0% and 68.0%, respectively. Local recurrence occurred in 13/75 (17.4%) patients, of which 2.7% (2/75) were extra-target lymph nodes. Grade 4 adverse events reported in this study included 10 cases (13.3%) of neutropenia, 1 case (1.3%) of anemia, and 2 cases (2.7%) of thrombocytopenia, without toxic-related deaths. Almost all (96%) patients completed the entire postoperative radiotherapy course, and 62 (82.7%) patients completed at least 2 cycles of chemotherapy.ConclusionPostoperative IMRT (clinical target volume including tumor bed, anastomosis, bilateral supraclavicular region, and superior mediastinal lymph nodes) combined with synchronous chemotherapy in patients with locally advanced thoracic esophageal squamous cell carcinoma was well tolerated, with a high local control rate and a low probability of recurrence outside the irradiation field.Clinical trial registrationhttps://clinicaltrials.gov/ChiCTR1900022689.

Project description:BackgroundConcurrent chemoradiotherapy followed by adjuvant chemotherapy (CCRT-AC) is currently recommended as the standard treatment for locally advanced nasopharyngeal carcinoma (LA-NPC). Neoadjuvant chemotherapy followed by concurrent chemoradiotherapy (NAC-CCRT) is an alternative strategy for decreasing tumor size and controlling micrometastases before main treatment. The aim of this study was to investigate and compare survival outcomes between LA-NPC patients treated with CCRT-AC and those treated with NAC-CCRT.MethodsThis retrospective cohort study included consecutive histologically confirmed LA-NPC patients that were treated with NAC-CCRT or CCRT-AC at Siriraj Hospital during the March 2010 to October 2014 study period. CCRT in both protocols consisted of 3-week cycles of cisplatin 100 mg/m2 with concurrent radiotherapy. Either NAC or AC consisted of 3-week cycles of cisplatin on day 1 and fluorouracil/leucovorin on days 1-4 for a maximum three cycles. The primary endpoint was 5-year overall survival (OS). Flexible parametric survival analysis was used, because the proportional hazards assumption of Cox regression was violated.ResultsOf the 266 LA-NPC patients that received treatment during the study period, 79 received NAC-CCRT and 187 received CCRT-AC. Median follow-up was 37 months. Significantly more patients with advanced clinical stage (stage IVA-IVB) received NAC-CCRT (86% in NAC-CCRT vs. 29% in CCRT-AC; p < 0.001). Compared to CCRT-AC in crude analysis, 3-year and 5-year OS of NAC-CCRT were 72% vs. 86% and 62% vs. 75% respectively (p = 0.059). Interestingly, the 3-year and 5-year post-estimation adjusted OS was 84% and 74% for NAC-CCRT and 81% and 70% for CCRT-AC, respectively (HR: 0.83, 95% confidence interval (CI): 0.45-1.56; p = 0.571). Also, adjusted analysis of distant-metastasis survival, NAC-CCRT showed HR was 0.79 (95% CI:0.37-1.72, p = 0.557). Conversely, adjusted analysis of locoregional relapse (LLR)-free survival revealed NAC-CCRT to have a significantly higher risk of LRR (HR: 2.18, 95% CI: 0.98-4.87; p = 0.057).ConclusionsThe results suggested that prognosis in the NAC-CCRT treated patients was not superior to that of the CCRT-AC treated individuals. In patients that receive neoadjuvant chemotherapy, locoregional relapse should be of concern. High-risk distant metastasis patients (N3 stage) that could achieve survival advantage from NAC-CCRT is an interesting and important topic for further study.

Project description:Pancreatic cancer has a dismal prognosis with 5-year overall survival rate of around 5%. Although surgery is still the best option in operable cases, majority of the patients who present in locally advanced stages are deemed inoperable. Novel approaches are therefore needed for the management of around 80% of these inoperable locally advanced pancreatic cancers (LAPC). Hyperthermia (39-43 °C) is a potent radiosensitizer and further enhances the action of gemcitabine, also a known radiosensitizer. Thus through triple sensitization, a combination of hyperthermia, radiotherapy and gemcitabine could be expected to improve the therapeutic outcomes in LAPC.This phase II randomized trial, HEATPAC in unresectable LAPC, explores the feasibility and efficacy of concurrent thermochemoradiotherapy (HTCTRT) over chemoradiotherapy (CTRT) alone with pre- and post-intervention FOLFIRINOX at standard dosage and schedule. Following 4 cycles of neoadjuvant FOLFIRINOX, patients with no metastasis and absence of gross peritoneal carcinomatosis would be randomized to either (a) control arm: concurrent CTRT with gemcitabine (400 mg/m2, weekly ×6) or (b) study arm: locoregional hyperthermia (weekly ×6 during radiotherapy) with concurrent CTRT (same as in control arm). All patients would receive simultaneous-integrated boost intensity-modulated radiation therapy to doses of 56Gy and 50.4Gy to the gross and clinical target volumes respectively delivered in 28 fractions over 5.5 weeks. Deep locoregional hyperthermia would be administered weekly and monitored with real-time intraduodenal multisensor thermometry probe. A temperature of 40-43 °C for 60 min would be aimed for each hyperthermia session. On completion of CTRT/HTCTRT, patients of both groups would receive an additional 8 cycles of FOLFIRINOX.The expected 1-year baseline overall survival with CTRT alone is considered as 40%. With HTCTRT, a survival advantage of +20% is expected. Considering α = 0.05 and β = 0.80 for sample size computation, a total of 86 patients would be equally randomized into the two treatment groups. This phase II study if found to be safe and effective, would form the basis of a future phase III randomized study.The trial has been registered with the ClinicalTrials.gov ( NCT02439593 ). The study has been approved by the Ethical Commissions of Basel and Zurich and is open for patient recruitment.

Project description:Objective: Radiotherapy or chemoradiotherapy has been preferred as the clinical therapeutic modalities to combat locally advanced esophageal squamous cell carcinoma (ESCC). The aim of this retrospective study is to ascertain combinatorial efficacy of anlotinib with concurrent radiotherapy (CCRT) rather than CCRT alone. Methods: Locally advanced ESCC patients registered between August 2018 to April 2019 in the third People's hospital of Zhengzhou, the First affiliated hospital of Zhengzhou University, Anyang Cancer Hospital, the Affiliated Hospital of Qingdao University were selected for this retrospective study; and these patients segregated into two groups subsequently who received combinatorial regimen with CCRT and anlotinib compared for treatment-related toxicity, response rates, safety, survival outcomes, than CCRT alone. Results: Progression free survival (PFS) was 0.577 (95% CI, 0.333-0.902, P = 0.014); the median overall survival time was 5 months (95% CI, 4.1-7.5) for the CCRT group, whereas 9 months (95% CI, 7.3-18.0) for the group received 'anlotinib with CCRT' (HR = 0.578, 95% CI, 0.337-0.924, P = 0.021). Overall objective response rates were considerable with a statistical difference between the two groups at 6 months (P1 = 0.027, P2 = 0.015) and 12 months (P1 = 0.012, P2 = 0.027). Overall adverse events are mitigated in combinatorial regimen than CCRT alone except the incidence of hypertension, which was higher in 'anlotinib with CCRT' group than CCRT group (P = 0.023). Total 13 patients exhibited hand-foot skin reactions in the group that received anlotinib in combination with CCRT. Anlotinib in combination with CCRT enhanced the overall survival (OS) rates, whereas incidence of treatment-related toxicity is minimized than CCRT alone. Conclusion: Combinatorial regimen of anlotinib with CCRT significantly enhanced clinical efficacy, safety and may benefit for treating the locally advanced ESCC patients.
