Randomised phase 3 study of adjuvant chemotherapy with or without nadroparin in patients with completely resected non-small-cell lung cancer: the NVALT-8 study.

ABSTRACT:

Background

Retrospective studies suggest that low molecular weight heparin may delay the development of metastasis in patients with resected NSCLC.

Methods

Multicentre phase 3 study with patients with completely resected NSCLC who were randomised after surgery to receive chemotherapy with or without nadroparin. The main exclusion criteria were R1/2 and wedge/segmental resection. FDG-PET was required. The primary endpoint was recurrence-free survival (RFS).

Results

Among 235 registered patients, 202 were randomised (nadroparin: n = 100; control n = 102). Slow accrual enabled a decrease in the number of patients needed from 600 to 202, providing 80% power to compare RFS with 94 events (α = 0.05; 2-sided). There were no differences in bleeding events between the two groups. The median RFS was 65.2 months (95% CI, 36-NA) in the nadroparin arm and 37.7 months (95% CI, 22.7-NA) in the control arm (HR 0.77 (95% CI, 0.53-1.13, P = 0.19). FDG-PET SUVmax ≥10 predicted a greater likelihood of recurrence in the first year (HR 0.48, 95% CI 0.22-0.9, P = 0.05).

Conclusions

Adjuvant nadroparin did not improve RFS in patients with resected NSCLC. In this study, a high SUVmax predicted a greater likelihood of recurrence in the first year.

Project description:Most long-term survivors of non-small-cell lung cancer (NSCLC) are patients who have had a completely resected tumour. However, this is only achievable in about 30% of the patients. Even in this highly selected group of patients, there is still a high risk of both local and distant failure. Adjuvant treatments such as chemotherapy (CT) and radiotherapy (RT) have therefore been evaluated in order to improve their outcome. In patients with stage II and III, administration of adjuvant platinum-based chemotherapy is now considered the standard of care, based on level 1 evidence. The role of postoperative radiation therapy (PORT) remains controversial. In the PORT meta-analysis published in 1998, the conclusions were that if PORT was detrimental to patients with stage I and II completely resected NSCLC, the role of PORT in the treatment of tumours with N2 involvement was unclear and further research was warranted. Thus at present, after complete resection, adjuvant radiotherapy should not be administered in patients with early lung cancer. Recent retrospective and non-randomised studies, as well as subgroup analyses of recent randomised trials evaluating adjuvant chemotherapy, provide evidence of the possible benefit of PORT in patients with mediastinal nodal involvement. The role of PORT needs to be evaluated also for patients with proven N2 disease who undergo neoadjuvant chemotherapy followed by surgery. The risk of local recurrence for N2 patients varies between 20% and 60%. Based on currently available data, PORT should be discussed for fit patients with completely resected NSCLC with N2 nodal involvement, preferably after completion of adjuvant chemotherapy or after surgery if patients have had preoperative chemotherapy. There is a need for new randomised evidence to reassess PORT using modern three-dimensional conformal radiation technique, with attention to normal organ sparing, particularly lung and heart, to reduce the possible over-added toxicity. Quality assurance of radiotherapy as well as quality of surgery - and most particularly nodal exploration modality - should both be monitored. A new large multi-institutional randomised trial Lung ART evaluating PORT in this patient population is needed and is now under way.

Project description:BackgroundAlthough platinum-based chemotherapy is accepted as adjuvant chemotherapy for resectable advanced non-small cell lung cancer (NSCLC), its completion rate is low due to severe adverse events. S-1 plus cisplatin is associated with relatively low toxicity and an unimpaired quality of life, and has been used for unresectable advanced lung cancer. We investigated the acceptability and feasibility of combination therapy with S-1 plus cisplatin as postoperative adjuvant chemotherapy following complete resection of pathological stage II-IIIA NSCLC.MethodsEnrolled patients received oral S-1 at a dose depending on their body weight twice daily for 21 days with intravenous cisplatin 60 mg/m2 on day 8, with 1 cycle comprising 5 weeks and 4 cycles. Patients received standard precautions against adverse events and received standard treatment when adverse events occurred. The primary endpoint was completion rate; secondary endpoints included safety, status of drug administration, disease-free survival (DFS), and overall survival (OS).ResultsA total of 19 patients [14 men, 5 women; mean age, 59.1 years; mean body surface area, 1.688 m2; 17 with an Eastern Cooperative Oncology Group performance status (PS) of 0 and 2 with a PS of 1; 7 (36.8%) with stage II disease and 12 (63.2%) with stage IIIA disease] were enrolled. The rate of completion of 4 cycles was 68.4%. Grade 3 adverse events that occurred in ≥10% of patients included neutropenia (21.1%), nausea (21.1%), and anorexia (15.8%). No grade 4 adverse events, febrile neutropenia, or treatment-related deaths occurred. The mean relative dose intensity (RDI) was 79% for S-1 and 80% for cisplatin. The 2-year DFS rate was 42.1%, and 2-year OS rate was 83.3%.ConclusionsThis study demonstrated the acceptability and feasibility of using S-1 plus cisplatin as adjuvant chemotherapy.Trial registrationThis study was registered on the UMIN clinical study registration site (protocol ID: UMIN000016191) on December 1, 2015.

Project description:BackgroundSince randomised clinical trials demonstrated a survival benefit of adjuvant chemotherapy (AC) following curative-intent lung surgery, AC has been implemented as a standard therapeutic strategy for patients with a completely resected IIA-IIIA non-small cell lung cancer (NSCLC). Regarding the moderate benefit of AC and the lack of literature on AC use in real-life practice, we aimed to evaluate compliance to guidelines, AC safety and efficacy in a less selected population.MethodsBetween January 2009 and December 2014, we retrospectively analysed 210 patients with theoretical indication of AC following curative-intent lung surgery for a completely resected IIA-IIIA NSCLC. The primary objective of this retrospective study was to evaluate compliance to AC guidelines. Secondary objectives included safety and efficacy of AC in real-life practice.ResultsAmong 210 patients with a theoretical indication of AC, chemotherapy administration was validated in multidisciplinary team (MDT) for 62.4% of them and 117 patients (55.7%) finally received AC. Patient's clinical conditions were the main reasons advanced in MDT for no respect to AC guidelines. Most of the patients received cisplatin-vinorelbine (86.3%) and AC was initiated within 8 weeks following lung surgery for 73.5% of patients. One-half of patients who received AC experienced side effects leading to either dose-intensity modification or treatment interruption. In real-life practice, AC was found to provide a survival benefit over surgery alone. Factors related to daily-life practice such as delayed AC initiation or incomplete AC planned dose received were not associated with an inferior survival.ConclusionsAlthough AC use might differ from guidelines in real-life practice, this retrospective study highlights that AC can be used safely and remains efficient among a less selected population. In the context of immunotherapy and targeted therapies development in peri-operative treatment strategies, the place of AC has to be precised in the future.
