Prognostic factors following complete resection of non-superior sulcus lung cancer invading the chest wall.

ABSTRACT:

Objectives

Locally advanced non-small-cell lung cancer (NSCLC) with chest wall invasion carries a high risk of recurrence and portends poor survival (30-40% and 20-50%, respectively). No studies have identified prognostic factors in patients who underwent R0 resection for non-superior sulcus NSCLC.

Methods

A retrospective review was conducted for all chest wall resections for NSCLC from 2004 to 2018. Patients with superior sulcus tumours, partial (<1 rib) or incomplete (R1/R2) resection or distant metastasis were excluded. Disease-free survival (DFS) and overall survival (OS) were estimated using the Kaplan-Meier method. Cox proportional hazards modelling was used to determine factors associated with DFS and OS.

Results

A total of 100 patients met inclusion criteria. Seventy-three (73%) patients underwent induction therapy, and all but 12 (16%) patients experienced a partial radiological response. A median of 3 ribs was resected (range 1-7), and 67 (67%) patients underwent chest wall reconstruction. The 5-year DFS and OS were 36% and 45%, respectively. Pathological N2 status [hazard ratio (HR) 3.12, confidence interval (CI) 1.56-6.25; P = 0.001], intraoperative blood transfusion (HR 2.24, CI 1.28-3.92; P = 0.005) and preoperative forced vital capacity (per % forced vital capacity, HR 0.97, CI 0.96-0.99; P = 0.013) were associated with DFS. Increasing pathological stage, lack of radiological response to induction therapy (HR 7.35, CI 2.35-22.99; P = 0.001) and cardiovascular comorbidity (HR 2.43, CI 1.36-4.36; P = 0.003) were associated with OS.

Conclusions

We demonstrate that blood transfusion and forced vital capacity are associated with DFS after R0 resection for non-superior sulcus NSCLC, while radiological response to induction therapy greatly influences OS. We confirm that pathological nodal status and pathological stage are reproducible determinants of DFS and OS, respectively.

Project description:Chest wall tumors are a relatively uncommon disease in clinical practice. Most of the published studies about chest wall tumors are usually single-center retrospective studies, involving few patients. Therefore, evidences regarding clinical conclusions about chest wall tumors are lacking, and some controversial issues have still to be agreed upon. In January 2019, 73 experts in thoracic surgery, plastic surgery, science, and engineering jointly released the Chinese Expert Consensus on Chest Wall Tumor Resection and Chest Wall Reconstruction (2018 edition). After that, numerous experts put forward new perspectives on some academic issues in this version of the consensus, pointing out the necessity to further discuss the points of contention. Thus, we conducted a survey through the administration of a questionnaire among 85 experts in the world. Consensus has been reached on some major points as follows. (I) Wide excision should be performed for desmoid tumor (DT) of chest wall. After excluding the distant metastasis by multi-disciplinary team, solitary sternal plasmacytoma can be treated with extensive resection and adjuvant radiotherapy. (II) Wide excision with above 2 cm margin distance should be attempted to obtain R0 resection margin for chest wall tumor unless the tumor involves vital organs or structures, including the great vessels, heart, trachea, joints, and spine. (III) For patients with chest wall tumors undergoing unplanned excision (UE) for the first time, it is necessary to carry out wide excision as soon as possible within 1-3 months following the previous surgery. (IV) Current Tumor Node Metastasis staging criteria (American Joint Committee on Cancer) of bone tumor and soft tissue sarcoma are not suitable for chest wall sarcomas. (V) It is necessary to use rigid implants for chest wall reconstruction once the maximum diameter of the chest wall defect exceeds 5 cm in adults and adolescents. (VI) For non-small cell lung cancer (NSCLC) invading the chest wall, wide excision with neoadjuvant and/or adjuvant therapy are recommended for patients with stage T3-4N0-1M0. As clear guidelines are lacking, these consensus statements on controversial issues on chest wall tumors and resection could possibly serve as further guidance in clinical practice during the upcoming years.
