Yang R, Wang H, Liu D, Li W. Incidence and risk factors of VTE in lung cancer: a meta-analysis. Ann Med 2024; 56:2390200. [PMID: 39183726 PMCID: PMC11348814 DOI: 10.1080/07853890.2024.2390200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 06/07/2024] [Accepted: 06/24/2024] [Indexed: 08/27/2024] Open
Abstract
BACKGROUND Lung cancer has maintained a high prevalence and mortality. Besides, venous thromboembolism (VTE) is the third most common disease of cardiovascular disease. Lung cancer with VTE usually influenced the overall survival in the follow-up. In the development of lung cancer, vigilance against and early diagnosis of VTE is of significance. METHODS We searched the databases of PubMed, Web of Science, Embase and Cochrane for related research up to 30 November 2023 and extracted information of incidence, odds ratio (OR), hazard ratio (HR) and their 95% confidence intervals (CIs), for evaluating the incidence of VTE and its risk factors. RESULTS A total of 54 articles and 873,292 records were included in our study. The pooled incidences of VTE and PE were 6% and 3%, respectively. Subgroup analysis revealed that the tumour, node and metastasis (TNM) stage (HR= 5.43, 95% CI: 2.42, 12.22), metastasis (HR= 2.67, 95% CI: 1.35, 5.29) and chemotherapy (HR= 2.27, 95% CI: 1.11, 4.65) had major influence on VTE occurrence. CONCLUSIONS Lung cancer complicated with VTE is unignorable, and its occurrence varies widely by tumour staging, tissue type and treatment. The results may aid in clinical decision-making about lung cancer in higher risk with VTE and weather receiving anticoagulant prophylaxis.

Thromb Haemost 2024; 124:223-235. [PMID: 37402391 PMCID: PMC10890911 DOI: 10.1055/a-2122-7780] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 06/27/2023] [Indexed: 07/06/2023]
Abstract
BACKGROUND The Caprini risk assessment model (RAM) is the most commonly used tool for evaluating venous thromboembolism (VTE) risk, a high score for arthroplasty can result in patients being classified as high risk for VTE. Therefore, its value in post-arthroplasty has been subject to debate. METHODS Retrospective data were collected from patients who underwent arthroplasty between August 2015 and December 2021. The study cohort included 3,807 patients, all of whom underwent a thorough evaluation using Caprini RAM and vascular Doppler ultrasonography preoperatively. RESULTS A total of 432 individuals (11.35%) developed VTE, while 3,375 did not. Furthermore, 32 (0.84%) presented with symptomatic VTE, while 400 (10.51%) were detected as asymptomatic. Additionally, 368 (9.67%) VTE events occurred during the hospitalization period, and 64 (1.68%) cases were detected during postdischarge follow-up. Statistical analysis revealed significant differences between the VTE and non-VTE groups in terms of ages, blood loss, D-dimer, body mass index >25, visible varicose veins, swollen legs, smoking, history of blood clots, broken hip, percent of female, hypertension, and knee joint arthroplasty (p < 0.05). The Caprini score was found to be significantly higher in the VTE group (10.10 ± 2.23) compared with the non-VTE group (9.35 ± 2.14) (p < 0.001). Furthermore, there was a significant correlation between the incidence of VTE and the Caprini score (r = 0.775, p = 0.003). Patients with a score ≥9 are at a high-risk threshold for postoperative VTE. CONCLUSION The Caprini RAM shows a significant correlation with the occurrence of VTE. A higher score indicates a greater likelihood of developing VTE. The score ≥9 is at particularly high risk of developing VTE.

Risk and Timing of Venous Thromboembolism After Surgery for Lung Cancer: A Nationwide Cohort Study. Ann Thorac Surg 2024; 117:289-296. [PMID: 37890818 DOI: 10.1016/j.athoracsur.2023.10.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 10/05/2023] [Accepted: 10/09/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND Venous thromboembolism (VTE) is a potentially preventable serious complication in patients with lung cancer undergoing thoracic operation. We examined the risk and timing of VTE after surgery for primary non-small cell lung cancer (NSCLC). METHODS All patients undergoing operation for NSCLC in Denmark between 2003 and 2021 were identified in the Danish Lung Cancer Registry. VTE events in the year after operation were assessed by stage, patient characteristics, and surgical procedure. RESULTS We identified 13,197 patients who underwent operation for NSCLC in 2003 to 2021 (mean age, 67.6 years; 50% female); 10,524 (79.7%) had stage I-II NSCLC, and 2673 (20.3%) had stage III-IV. During 1-year follow-up, there were 335 VTE events, yielding a rate of 2.87 events/100 person-years and an absolute risk of 3.3% (95% CI, 2.3-4.0). VTE risk increased with advancing cancer stage (1.8% for stage I vs 3.9% for stage IV) but varied little by pathologic type, sex, and comorbidity level. Bilobectomy was associated with highest VTE risk (4.8%; 95% CI, 3.2-6.9), followed by pneumonectomy (3.5%; 95% CI, 2.3-5.0). The hazard of VTE was highest during the first 3 months after operation, after which it declined. For stage IV cancer, hazards increased again after 6 months. At 1 year, all-cause death was 12.6% (95% CI, 12.0%-13.1%). CONCLUSIONS VTE developed in 3.3% of patients undergoing operation for NSCLC, most commonly within 3 months postoperatively. Prolonged thromboprophylaxis could be considered, particularly in those with advanced cancer stage and undergoing extended resections.

Abstract
Cancer patients are at higher risk for venous thromboembolism (VTE). Several risk assessment models (RAM), including the Khorana and COMPASS-CAT, were developed to help predict the occurrence of VTE in cancer patients on active anti-cancer therapy. We aim to study the prevalence and predictors of VTE among patients with non-small cell lung cancer (NSCLC) and compare both RAMs in predicting VTE in patients with NSCLC were retrospectively reviewed. Variables known to increase the risk of VTE were collected and risk of VTE was assessed using both Khorana and COMPASS-CAT RAM. A total of 508 patients (mean age ± SD, 58.4 ± 12.2 years) were enrolled. Most (n = 357, 70.3%) patients had adenocarcinoma, and 333 (65.6%) patients had metastatic disease. VTE were confirmed in 76 (15.0%) patients. Rates were higher among patients with metastatic disease (19.8%, p < 0.001), adenocarcinoma (17.4%, p = 0.01) and those treated with immunotherapy (23.5%, p = 0.014). VTE rates were 21.2%, 14.1% and 13.9% among those with high (n = 66), intermediate (n = 341) and low (n = 101) Khorana risk scores, respectively (p = 0.126). On the other hand, 190 (37.4%) were classified as high risk by the COMPASS-CAT RAM; 52 (27.4%) of them had VTE compared to 24 (7.5%) of the remaining 318 (62.6%) classified as Low/Intermediate risk level, p < 0.001. In conclusion, patients with NSCLC are at high risk for VTE, especially those with adenocarcinoma, metastatic disease and when treated with immunotherapy. Compared to Khorana RAM, COMPASS-CAT RAM was better in identifying more patients in high-risk group, with higher VTE rate.

Incidence, risk factors, and outcomes of venous thromboembolism in patients undergoing surgery for retroperitoneal tumors: a propensity-matched retrospective cohort study. Int J Surg 2023; 109:2689-2695. [PMID: 37578462 PMCID: PMC10498861 DOI: 10.1097/js9.0000000000000429] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Accepted: 04/21/2023] [Indexed: 08/15/2023]
Abstract
BACKGROUND Venous thromboembolism (VTE) is a common postoperative complication; however, the incidence and risk stratification of postoperative VTE in patients with retroperitoneal tumor remains unclear. The authors aim to quantify the incidence, identify risk factors, and determine the outcomes of VTE in patients undergoing retroperitoneal tumor surgery. METHODS The authors retrospectively reviewed the characteristics, perioperative outcomes, and overall survival (OS) of patients (VTE and non-VTE) who underwent retroperitoneal tumor surgery between 2015 and 2020. Perioperative and oncologic outcomes were compared using propensity-matching and Cox analyses. RESULTS Of 1223 patients with retroperitoneal tumor surgery, 2.1% had VTE. Age [odds ratio (OR) 1.140, 95% CI: 1.053-1.239, P =0.004], recurrence (OR 1.851, 95% CI: 1.241-2.761, P =0.003), and vascular resection (OR 2.036, 95% CI: 1.054-3.934, P =0.034) were independent risk factors, with significant between-group differences regarding age, recurrence, sarcoma, organ resection, vascular resection, and operation time. No between-group differences in 30-day all-cause mortality (8 vs. 4%, OR 0.657, 95% CI: 0.375-1.151, P =0.427) and major complications (12 vs. 8%, OR 0.775, 95% CI: 0.483-1.244, P =0.572) were observed. Mean hospitalization duration (20.1 vs. 22.9 days, OR 1.153, 95% CI: 1.022-1.386, P =0.033) and ICU stay (3.2 vs. 5.5 days, OR 1.193, 95% CI: 1.034-1.347, P =0.012) were shorter in non-VTE versus VTE, respectively, with inferior OS (hazard ratio 2.090, 95% CI: 1.014-4.308, P =0.046) in VTE. CONCLUSIONS Age, recurrence, and vascular resection are positively associated with VTE, which is associated with inferior OS.

ERJ Open Res 2023; 9:00675-2022. [PMID: 37583968 PMCID: PMC10423981 DOI: 10.1183/23120541.00675-2022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 05/04/2023] [Indexed: 08/17/2023] Open
Abstract
Background Whether pre-operative biopsy affects post-operative recurrence and metastasis of lung cancer patients is still controversial. Methods In order to clarify these disputes, we collected relevant literature to conduct a meta-analysis. To validate the results of the meta-analysis, we retrospectively analysed 575 patients with stage I lung adenocarcinoma who underwent surgical resection at our centre from 2010 to 2018 using propensity score matching and competing risk models. Results 5509 lung cancer patients from 11 articles were included in the meta-analysis. Summary analysis showed that the total recurrence rate of the biopsy group was higher than that of the nonbiopsy group (risk ratio 1.690, 95% CI 1.220-2.330; p=0.001). After propensity score matching, we found that there was no significant correlation between biopsy and total recurrence (risk ratio 1.070, 95% CI 0.540-2.120; p=0.850). In our cohort, of 575 stage I lung adenocarcinomas, 113 (19.7%) patients underwent pre-operative biopsy. During a median (interquartile range) follow-up of 71 (57-93) months, multivariable analyses showed pre-operative biopsy in the overall observation cohort (subdistribution hazard ratio (SHR) 1.522, 95% CI 0.997-2.320; p=0.051) and in the propensity score-matched cohort (SHR 1.134, 95% CI 0.709-1.810; p=0.600) was not significantly correlated with the risk of recurrence and metastasis. Moreover, the pre-operative biopsy did not affect disease-free survival (SHR 0.853, 95% CI 0.572-1.273; p=0.438) or overall survival (SHR 0.647, 95% CI 0.352-1.189; p=0.161). Conclusion Pre-operative biopsy might not increase the risk of recurrence and metastasis, suggesting that these procedures might be safe for patients with stage I lung adenocarcinoma whose diagnosis is difficult to determine before surgery.
