[Resection and reconstruction of the chest wall for primary or metastatic tumours].

PURPOSE OF THE STUDY The aim of the study was to assess mortality and the complication rate after the extensive resection of chest wall tumour and subsequent soft tissue reconstruction. We wanted to evaluate the justification for major surgery in the group of patients with primary or secondary tumours, including those with an advanced stage of disease. MATERIALS AND METHODS A total of 35 patients after major chest wall resection within an eight-year period (2000-2008) were analysed retrospectively. A major resection was defined as resection of 75 cm2 or more of full thickness of the chest wall. There were 19 cases of primary malignant tumour of the chest wall, 10 cases of secondary tumour, and 6 cases of benign or semi-malignant lesions. The chest was stabilised with the help of either polypropylene or a double layer mesh of polyester covered with polyurethane. For soft tissue reconstruction, a musculocutaneous flap was used in 18 cases. The number of resected ribs ranged from two to seven. The vertebral body was partially resected in four cases, and total sternectomy was performed in two cases. This surgery was carried out with potentially curative intent in 30 (85.7%) and with palliative intent in five patients (14.3%). RESULTS No post-operative mortality occurred. The complication rate was 17.1 %. The one-year survival rate was 88.6 %. There were seven long-term survivors at 5 or more years after resection of the chest wall for soft tissue sarcoma. Local recurrence occurred in six patients (17.1%). Neither the type of prosthesis nor the type of surgical procedure influenced the complication rate. DISCUSSION Chest wall resection is an established surgical procedure in the treatment of primary chest wall tumours and, occasionally, solitary metastatic disease. The groups of patients reported in the literature have been heterogeneous and usually small, and thus an estimation of the true risk of the major procedure is difficult. Three studies involving large patient groups published in the last 11 years have shown morbidity in 24.4%, 33.2% and 46.0% of patients and mortality in 7.0%, 3.8% and 4.1% of patients, respectively. The results in our group of unselected patients are comparable with these studies; however, we did not perform extensive procedures like pneumonectomy and chest wall resection, or extended fore quarter amputation. CONCLUSIONS Complete resection of the chest wall is feasible even in advanced tumours without significant peri-operative morbidity and mortality. Major chest wall resection as a palliative procedure remains selective for motivated patients in a good physical condition but with low quality of life caused by a chest wall tumour.
