Prospective study of quality of life after lung cancer resection.

BACKGROUND: Surgical resection with curative-intent remains the gold standard for clinically operable early-stage non-small cell lung cancer (NSCLC). This goal can be accomplished using a minimally invasive option, e.g., video assisted thoracic surgery (VATS) or standard thoracotomy. Surgical techniques continue to evolve and few studies have compared the QOL of patients managed with these procedures using current approaches. The primary goal of this study was to investigate differences between patients managed surgically via VATS compared to thoracotomy with respect to ratings of chronic pain, anxiety/depression and quality of life (QOL). The secondary goal was to investigate differences between patients converted from VATS to thoracotomy versus those managed with the originally with thoracotomy. METHODS: We conducted a prospective cross sectional design study comparing the QOL after surgical resection of NSCLC. Data were obtained between 3-12 months postoperatively, from patients with potentially resectable stage I-IIIa NSCLC, who underwent a thoracotomy or VATS resection. All patients were consented. Pain was evaluated with a 0 to 10 numeric pain assessment scale (NAS), mood with the Hospital Anxiety and Depression Scale (HADS) (mood disorders) and QOL with FACT-L (Functional Assessment of Cancer Therapy-Lung). RESULTS: A total of 97 patients with stage I-IIIa lung cancer were enrolled; of these 66 (68%) underwent a standard thoracotomy and 31 (32%) underwent VATS resection. The preferred surgical approach was a thoracotomy for patients with stage IIIa lung cancer, or patients requiring a pneumonectomy or a bi-lobectomy. There were no significant differences between VATS and thoracotomy patients in ratings of chronic pain, mood disorders, or QOL. Conversion from VATS to thoracotomy occurred in 22 (23%) of patients. There were no significant differences between VATS conversion to thoracotomy and those with initial thoracotomy procedures in ratings of chronic pain, mood disorders, or QOL. Conversion from VATS to standard thoracotomy occurred more commonly early in the series. CONCLUSIONS: While previous studies have shown that VATS offers an early advantage with regards to perioperative outcomes, our study demonstrated that VATS and thoracotomy patients had similar late QOL outcomes.

Postthoracotomy Pain Syndrome Following Surgery for Lung Cancer: Symptoms and Impact on Quality of Life.

Postthoracotomy pain syndrome (PTPS) is a common complication following thoracic surgery. Most studies examining the influence of PTPS on patient-reported symptoms include few patients managed using a minimally invasive approach. Associated sensory changes, potentially neuropathic in origin, are not well described. We therefore examined the symptoms and quality of life (QOL) of patients with and without PTPS who underwent a standard thoracotomy (n = 43) or minimally invasive surgery (n = 54). Patients in this prospective, cross-sectional study completed questionnaires to assess pain (McGill Pain Questionnaire), neuropathic symptoms (Neuropathic Symptom Questionnaire), symptom distress (Symptom Distress Scale), anxiety and depression (Hospital Anxiety and Depression Scale), and QOL (Functional Assessment Cancer Therapy-Lung). Excepting younger age (p = .009), no demographic or surgical characteristic differentiated patients with and without PTPS. Patients with PTPS described discomfort as pain only (15.1%), neuropathic symptoms only (30.2%) or pain and neuropathic symptoms (54.7%). Scores differed between patients with and without PTPS for symptom distress (p < .001), anxiety and depression (p < .001), and QOL (p = .009), with higher distress associated with PTPS. Despite new surgical techniques, PTPS remains common and results in considerable distress. A focused assessment is needed to identify all experiencing this condition, with referral to pain management specialists if symptoms persist.
