Quality of Life Evolution after Pulmonary Metastasectomy: A Prospective Study Comparing Isolated Lung Perfusion with Standard Metastasectomy

Impact of Metastasectomy on Patient-Reported Outcomes and Health-Related Quality of Life

This article explores the impact of pulmonary metastasectomy on patient health-related quality of life, emphasizing the role of patient-reported outcome measures (PROMs) in evaluating surgical outcomes. It provides a detailed analysis of studies reporting PROMs in lung metastasectomy, compares different surgical techniques, and discusses the broader implementation of PROMs in this setting. Limitations and future directions for improving PROMs integration in clinical practice are also addressed, highlighting the importance of these measures in enhancing patient-centered care and shared decision-making.

Improving survival after pulmonary metastasectomy for sarcoma: analysis of prognostic factors

BACKGROUND

Metastatic sarcoma confers a grave prognosis to patients and poses a management dilemma for clinicians. Pulmonary metastasectomy is frequently performed for the recurrence of sarcomatous tumours in the lung, but the evidence-base is poor. No guidelines exist to inform clinicians on appropriate patient selection and surgical technique.

AIM

This review aims to establish and analyse the most important prognostic factors for survival post pulmonary metastasectomy for recurrent sarcoma. We summarise the key tumour, peri-operative and patient characteristics that should guide surgical management.

METHODS

A comprehensive search of the literature utilising OVID Medline and PubMed databases was conducted to identify all relevant research within the past 15 years. We evaluated all articles that specifically studied sarcoma patients (both bone and soft tissue).

CONCLUSION

Disease-free interval and tumour burden remain important prognostic factors, while tumour grade is likely not significant. VATS is a safe and viable alternative to thoracotomy without sacrificing survival outcomes. No single peri-operative characteristic provides useful prognostic information in isolation.

The ECLIPSE Study: Efficacy of cryoablation on metastatic lung tumors with a 5-year follow-up

INTRODUCTION

The ECLIPSE study aimed to assess the feasibility and efficacy of cryoablation for local tumor control in patients with pulmonary metastatic disease over five years of follow-up.

METHODS

ECLIPSE was a prospective, multicenter, single-arm study which included patients treated with cryoablation if they had 1-5 metastatic lung tumors, each with a diameter of ≤ 3.5 cm. Patients were followed up over the course of five years. The primary endpoint was local tumor control, both per tumor and per patient; secondary endpoints included cancer-specific survival, overall survival (OS), and quality of life. Quality of life was assessed using the Karnofsky Performance Score, the Eastern Cooperative Oncology Group Performance Score, and the Short Form-12 health survey.

RESULTS

The study included 40 patients across 4 sites (3 US and 1 European). A total of 60 metastatic pulmonary tumors were treated with 48 cryoablation procedures. Overall local tumor control rates were 87.9% (29/33) and 79.2% (19/24) per tumor, and 83.3% (20/24) and 75.0% (15/20) per patient, at 3 and 5 years respectively. A total of 5 treated patients demonstrated local progression throughout the duration of the study. Disease specific survival rate was of 74.8% at 3 years and 55.3% at 5 years while overall survival at 3 and 5 years were of 63.2% and 46.7% respectively. Patient quality of life scores did not reach statistical significance.

CONCLUSIONS

Cryoablation is an effective means of long-term local tumor control in patients with metastatic pulmonary tumors.

Pulmonary metastasectomy in colorectal carcinoma

Colorectal cancer (CRC) is one of the leading causes of cancer-related deaths worldwide. It is estimated that 50% of all patients with CRC develop metastases, most commonly in the liver and the lung. Lung metastases are seen in approximately 10–15% of all patients with CRC. A large number of these patients with metastatic CRC can only receive palliative treatment due to invasion of other organs and disseminated disease. However, a subset of these patients present with potentially resectable metastases. Pulmonary metastasectomy is considered to be a potentially curative treatment for selected patients with resectable metastatic CRC. Current data suggest that patients that undergo pulmonary metastasectomy have 5-year survival rates of approximately 40%. However, the majority of data published regarding lung metastasectomy is based on small, retrospective case series. Due to this lack of prospective data, it is still unclear which subset of patients will benefit most from curative-intent surgery. Furthermore, there is also controversy regarding which prognostic and genetic factors are related to survival outcomes and whether there is a difference between open and thoracoscopic approaches in terms of overall and disease-free survival. In this review, we aim to summarize the latest data on prognostic factors and survival outcomes after pulmonary metastasectomy in patients with metastatic CRC.

Use of the lung cancer-specific Quality of Life Questionnaire EORTC QLQ-LC13 in clinical trials: A systematic review of the literature 20 years after its development

The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13) covers 13 typical symptoms of lung cancer patients and was the first module developed in conjunction with the EORTC core quality-of-life (QL) questionnaire. This review investigates how the module has been used and reported in cancer clinical trials in the 20 years since its publication. Thirty-six databases were searched with a prespecified algorithm. This search plus an additional hand search generated 770 hits, 240 of which were clinical studies. Two raters extracted data using a coding scheme. Analyses focused on the randomized controlled trials (RCTs). Of the 240 clinical studies that were identified using the LC13, 109 (45%) were RCTs. More than half of the RCTs were phase 3 trials (n = 58). Twenty RCTs considered QL as the primary endpoint, and 68 considered it as a secondary endpoint. QL results were addressed in the results section of the article (n = 89) or in the abstract (n = 92); and, in half of the articles, QL results were presented in the form of tables (n = 53) or figures (n = 43). Furthermore, QL results had an impact on the evaluation of the therapy that could be clearly demonstrated in the 47 RCTs that yielded QL differences between treatment and control groups. The EORTC QLQ-LC13 fulfilled its mission to be used as a standard instrument in lung cancer clinical trials. An update of the LC13 is underway to keep up with new therapeutic trends and to ensure optimized and relevant QL assessment in future trials.

Phase II multicenter clinical trial of pulmonary metastasectomy and isolated lung perfusion with melphalan in patients with resectable lung metastases

INTRODUCTION

The 5-year overall survival rate of patients undergoing complete surgical resection of pulmonary metastases (PM) from colorectal cancer (CRC) and sarcoma remains low (20-50%). Local recurrence rate is high (48-66%). Isolated lung perfusion (ILuP) allows the delivery of high-dose locoregional chemotherapy with minimal systemic leakage to improve local control.

METHODS

From 2006 to 2011, 50 patients, 28 male, median age 57 years (15-76), with PM from CRC (n = 30) or sarcoma (n = 20) were included in a phase II clinical trial conducted in four cardiothoracic surgical centers. In total, 62 ILuP procedures were performed, 12 bilaterally, with 45 mg of melphalan at 37°C, followed by resection of all palpable PM. Survival was calculated according to the Kaplan-Meier method.

RESULTS

Operative mortality was 0%, and 90-day morbidity was mainly respiratory (grade 3: 42%, grade 4: 2%). After a median follow-up of 24 months (3-63 mo), 18 patients died, two without recurrence. Thirty patients had recurrent disease. Median time to local pulmonary progression was not reached. The 3-year overall survival and disease-free survival were 57% ± 9% and 36% ± 8%, respectively. Lung function data showed a decrease in forced expiratory volume in 1 second and diffusing capacity of the alveolocapillary membrane of 21.6% and 25.8% after 1 month, and 10.4% and 11.3% after 12 months, compared with preoperative values.

CONCLUSION

Compared with historical series of PM resection without ILuP, favorable results are obtained in terms of local control without long-term adverse effects. These data support the further investigation of ILuP as additional treatment in patients with resectable PM from CRC or sarcoma.

Midterm changes in quality of life: a prospective evaluation after open pulmonary metastasectomy

BACKGROUND

Pulmonary metastasectomy has gained the status of a standard treatment for oligometastases of various primaries. Given that the consequences for quality of life (QoL) remain unclear, we initiated this study to characterize the therapy-induced effects of pulmonary metastasectomy on QoL.

METHODS

From 2008 to 2010, patients scheduled for metastasectomy were prospectively evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) and the lung cancer module (LC13) questionnaire and again 3 months later. We analyzed QoL changes over time and looked for sex-specific and age-specific (<70 versus >70 years) differences.

RESULTS

A total of 126 cases were analyzed. The median age of the 73 male and 53 female patients was 59.2 years (range, 24.2 to 83.9). There was no significant change between preoperative and postoperative QoL values for emotional, cognitive, and social functioning. Significant deterioration of QoL items was found for physical functioning (-11.0; p < 0.001), role functioning (-16.4; p < 0.001), fatigue (11.1; p < 0.001), pain (15.0; p < 0.001), and dyspnea (16.9; p < 0.001). There were no differences between sexes concerning preoperative and postoperative scores. Younger patients (<70 years) had more preoperative symptoms (1.9; p = 0.03) and a worse function (2.2; p = 0.04). A tendency was found for decreased global QoL (-6.0; p = 0.08) in the older age group (>70 years) after metastasectomy.

CONCLUSIONS

Pulmonary metastasectomy can be offered every patient with a chance of cure or prolongation of life because the anticipated midterm changes in QoL are of moderate clinical importance, and the change in global health-related QoL is trivial.
