Abstract

AIM:We investigated blood parameters in patients with inoperable stage III non-small cell lung cancer (NSCLC) to predict individual outcomes after definitive chemoradiotherapy (CRT). PATIENTS AND METHODS:Blood parameters of consecutive patients undergoing definitive CRT between 2010 and 2016 for inoperable stage III NSCLC before multimodal treatment and at first follow-up were measured and analyzed. RESULTS:Blood parameters from 99 patients were evaluated. Histologically, about 50% of patients had an adenocarcinoma. All patients received platinum-based sequential or concurrent CRT. The median total dose to the primary tumor was 60 (range=48-70) Gy. On multivariate analysis after adjustment for all co-founders, median overall survival for pre-treatment cutoffs were: lactate dehydrogenase (LDH) >250 U/l was 17 vs. 27 months [hazard ratio (HR)=2.05, 95% confidence intervaI (CI)=1.15-3.66; p=0.015], thrombocytosis >400×106/l: 11 vs. 23 months (HR=2.75, 95% CI=1.1-6.88; p=0.03), hypoalbuminemia <3.5 g/dl: 12 vs. 24 months (HR=2.42, 95% CI=1.21-4.84; p=0.013) and post-treatment neutrophilia >7×106/l: 12 vs. 27 months (HR=2.5, 95% CI=1.21-5.17; p=0.013). CONCLUSION:Pre-treatment elevated LDH, thrombocytosis, hypoalbuminemia and post-treatment neutrophilia were associated with significantly worse overall survival in patients with inoperable stage III NSCLC treated with CRT. Patients with both pre-therapeutic elevated LDH and hypoalbuminemia demonstrated a dismal prognosis despite completion of multimodal treatment.

摘要

目的: 我们研究了不能手术的 III 期非小细胞肺癌 (NSCLC) 患者的血液参数,以预测确定性放化疗 (CRT) 后的个体结局。 患者和方法: 测量并分析连续患者在多模式治疗前和首次随访前接受确定性 CRT (2010年) 和 2016 例不能手术的 III 期 NSCLC 的血液参数。 结果: 对 99 例患者的血液参数进行了评估。组织学上,约 50% 的患者为腺癌。所有患者均接受以铂类为基础的序贯或同期 CRT。原发肿瘤的中位总剂量为 60 (范围 = 48-70) Gy。在对所有共同创始人进行校正后的多变量分析中,治疗前的中位总生存期临界值为: 乳酸脱氢酶 (LDH) >250 U/l 为 17 vs。27 个月 [风险比 (HR)= 2.05,95% 置信 intervaI (CI)= 1.15-3.66; p = 0.015],血小板增多> 400 × 106/l: 11 vs. 23 个月 (HR = 2.75,95% CI = 1.1-6.88; p = 0.03),低白蛋白血症 <3.5g/dl: 12 vs. 24 个月 (HR = 2.42,95% CI = 1.21-4.84; p = 0.013) 和治疗后中性粒细胞减少> 7 × 106/l: 12 vs. 27 个月 (HR = 2.5,95% CI = 1.21-5.17; p = 0.013)。 结论: 在接受 CRT 治疗的不能手术的 III 期 NSCLC 患者中,治疗前 LDH 升高、血小板增多、低白蛋白血症和治疗后中性粒细胞增多与总生存期显著较差相关。尽管完成了多模式治疗,但治疗前 LDH 升高和低白蛋白血症的患者均表现出令人沮丧的预后。

METHODS:BACKGROUND:The objectives of this study are to assess the chest drainage volumes of patients undergoing anatomic resection of non-small cell lung carcinoma and to determine the safety and effectiveness of administering enoxaparin for thromboprophylaxis. METHODS:A total of 77 patients were included in the study. A study was conducted on the first group of 42 patients in which enoxaparin prophylaxis (enoxaparin, 40 mg) was subcutaneously injected once a day for a period of three days after the patients underwent anatomic pulmonary resection between March 2016 and March 2018. An enoxaparin-free group was identified and included 35 patients who received no enoxaparin prophylaxis after undergoing anatomic pulmonary resection between February 2013 and February 2016. We compared the changes in hemoglobin (Hb) levels, postoperative 3-day drainage volume, transfusion volume, pulmonary complications and length of stay between the two groups. RESULTS:No differences in postoperative Hb levels, chest drainage volume, transfusion volume, postoperative complications, and length of stay were observed between the two groups. Deep-vein thrombosis was noted in a patient in the enoxaparin-free group. No major bleeding was noted in either group. CONCLUSION:We found that for patients undergoing anatomic resection of primary lung cancer, the blood transfusion and chest drainage volumes did not differ, regardless of whether the patients were given enoxaparin. To the best of our knowledge, the impact of low-molecular-weight heparin on chest tube drainage volume for patients undergoing anatomic resection of non-small cell lung carcinoma has not been investigated before.

METHODS::The aim of the present study was to compare the safety and efficacy of cryoablation (CA) and microwave ablation (MWA) as treatments for non-small cell lung cancer (NSCLC). Patients with stage IIIB or IV NSCLC treated with CA (n=45) or MWA (n=56) were enrolled in the present study. The primary endpoint was progression-free survival (PFS); the secondary endpoints included overall survival (OS) time and adverse events (AEs). The median PFS times between the two groups were not significantly different (P=0.36): CA, 10 months [95% confidence interval (CI), 7.5-12.4] vs. MWA, 11 months (95% CI, 9.5-12.4). The OS times between the two groups were also not significantly different (P=0.07): CA, 27.5 months (95% CI, 22.8-31.2 months) vs. MWA, 18 months (95% CI, 12.5-23.5). For larger tumors (>3 cm), patients treated with MWA had significantly longer median PFS (P=0.04; MWA, 10.5 months vs. CA, 7.0 months) and OS times (P=0.04; MWA, 24.5 months vs. CA, 14.5 months) compared patients treated with CA. However, for smaller tumors (≤3 cm), median PFS (P=0.79; MWA, 11.0 months vs. CA, 13.0 months) and OS times (P=0.39; MWA, 30.0 months vs. CA, 26.5 months) between the two groups did not differ significantly. The incidence rates of AEs were similar in the two groups (P>0.05). The number of applicators, tumor size and length of the lung traversed by applicators were associated with a higher risk of pneumothorax and intra-pulmonary hemorrhage in the two groups. Treatment with CA resulted in significantly less intraprocedural pain compared with treatment with MWA (P=0.001). Overall, the present study demonstrated that CA and MWA were comparably safe and effective procedures for the treatment of small tumors. However, treatment with MWA was superior compared with CA for the treatment of large tumors.

METHODS:BACKGROUND:BRAF mutations occurring in 1%-5% of patients with non-small-cell lung cancer (NSCLC) are therapeutic targets for these cancers but the impact of the exact mutation on clinical activity is unclear. The French National Cancer Institute (INCA) launched the AcSé vemurafenib trial to assess the efficacy and safety of vemurafenib in cancers with various BRAF mutations. We herein report the results of the NSCLC cohort. PATIENTS AND METHODS:Tumour samples were screened for BRAF mutations in INCA-certified molecular genetic centres. Patients with BRAF-mutated tumours progressing after ≥1 line of treatment were proposed vemurafenib 960 mg twice daily. Between October 2014 and July 2018, 118 patients were enrolled in the NSCLC cohort. The primary outcome was the objective response rate (ORR) assessed every 8 weeks (RECIST v1.1). A sequential Bayesian approach was planned with an inefficacy bound of 10% for ORR. If no early stopping occurred, the treatment was of interest if the estimated ORR was ≥30% with a 90% probability. Secondary outcomes were tolerance, response duration, progression-free survival (PFS), and overall survival (OS). RESULTS:Of the 118 patients enrolled, 101 presented with a BRAFV600 mutation and 17 with BRAFnonV600 mutations; the median follow-up was 23.9 months. In the BRAFnonV600 cohort, no objective response was observed and this cohort was stopped. In the BRAFV600 cohort, 43/96 patients had objective responses. The mean Bayesian estimated success rate was 44.9% [95% confidence intervals (CI) 35.2%-54.8%]. The ORR had a 99.9% probability of being ≥30%. Median response duration was 6.4 months, median PFS was 5.2 months (95% CI 3.8-6.8), and OS was 10 months (95% CI 6.8-15.7). The vemurafenib safety profile was consistent with previous publications. CONCLUSION:Routine biomarker screening of NSCLC should include BRAFV600 mutations. Vemurafenib monotherapy is effective for treating patients with BRAFV600-mutated NSCLC but not those with BRAFnonV600 mutations. TRIAL REGISTRATION:ClinicalTrials.gov identifier: NCT02304809.
