Full textBackground: Breast carcinoma is the most common type of cancer in women worldwide and is still regarded as a systemic disease. After primary treatment five-year survival rates around 80% are reported. However, the mean survival time of stadium-IV classified patients is 20-30 months. 5-15% of patients appear with isolated metastases of the lungs which can be considered as an oligometastatic and, therefore, stable intermediate stage in disease process. Several studies point out that especially these women are more likely to benefit from resection of lung metastases than from systemic therapy alone. Furthermore, there is the possibility of a discordant expression of typical receptors (Estrogen-, Progesterone- and HER2-receptor) between primary breast cancer and its paired metastases. As a result a change in treatment regimen might be necessary. Objective: The aim of the present study was to evaluate long-time survival of patients with lung metastases from breast cancer who have been operated exclusively with a new parenchyma-saving and lobe-sparing 1318-nm-lasertechnique. Additionally, the identification of independent prognostic factors was of interest. Furthermore, existence and magnitude of receptor discordance, specifically for distant pulmonary metastases, should be proved. Patients and methods: Within this retrospective study between 1996 and 2012 102 patients (mean age 58; range 33-78 years) underwent curative laser metastasectomy and systematic lymphadenectomy. Inclusion criteria were complete resection of primary breast cancer and absence of extrapulmonary/-thoracal metastases or its previous total treatment. Although there were no limitations regarding the number of metastases, technical resectability and functional operability had to be assumed after the preoperative diagnostics. Kaplan-Meier-analysis was performed to assess overall survival in all patients and selected subgroups. Uni- and multivariate analyses of prognostic factors were performed using the Cox-proportional-hazard model. Comparison of the receptor status of primary breast cancer and paired lung metastases was assessed by the McNemare method. Significant results were assumed if p-values were <0.05. Results: In total 936 intrapulmonary nodules had been resected, including 716 histopathologically confirmed breast cancer metastases. The amount reached from a single metastasis up to 61 two-staged removed pulmonary nodules (mean 7 per patient). The lobectomy rate was 0.98%. In 7.8% of all cases segment-resections, also performed by laser, were possible. Complete resection was achieved in 73.5% (n=75). The median overall survival time was 43 months and the five-year survival rate was 46.1%. As independent prognostic factors resection status (p=0.02), involvement of intrathoracal lymph nodes (p=0.001) and expression of estrogen receptor (p=0.018) were identified. The mortality rate in case of lymph node involvement and negative estrogen receptor status was increased by 3.2- and 2-fold, respectively. The number of resected metastases, type of lung affection (uni-/bilateral), disease free interval after primary breast surgery ( 36 months), and expression of progesterone receptor had no significant influence on survival. Data concerning the primary and metastatic hormone receptor- and HER2-status were available in 88.2% (n=90) and 62.7% (n=64) of all cases, respectively. Discordant results appeared in 26.7%, 41.1%, and 28.1% regarding the estrogen-, progesterone- and HER2-receptor. Significance of these findings had only been proved for estrogen receptor (p=0.002). A subanalysis of the present study revealed that 65.5% of 157 breast cancer patients who presented with newly occurred radiologically detectable pulmonary nodules had histopathologically confirmed paired metastases. The remaining results showed malignancies other than known breast cancer, and in approximately 20% of all cases there were benign lesions. Conclusions: The results of the present study emphasize the favorable effect of the lung metastasectomy on survival of selected breast cancer patients with isolated pulmonary oligometastatic disease. Via the use of the parenchyma-saving 1318nm-lasertechnique even in case of distinct and bilateral pulmonary metastatic involvement, increased rates of complete resection without substantial loss of lung function can be achieved. Therefore, an adequate quality of life is provided. In comparison with conventional surgery practices, this procedure creates similar survival rates despite higher numbers of resected lung metastases. That is why the number of preoperatively diagnosed metastases should have little influence on decision upon surgery. Thus, an extension of inclusion criteria seems reasonable. Again, complete resection appeared as one of the most important prognostic parameters and should, therefore, be the main objective of the surgeon. The poorer outcome for women with incomplete resections and the results of studies on systemic therapy implicate once more that breast cancer patients are more likely to benefit from the resection of their pulmonary metastases than from medical treatment alone. Furthermore, for the first time according to our knowledge, despite radical excision intrathoracal lymph node involvement has been proved as a significant negative predictive determinant in a collective of patients with isolated pulmonary metastases of breast cancer. Nevertheless, an intraoperative systematic lymph node sampling should be considered, at least until further studies are presented. In reference to the surgical approach of lung carcinoma, as circumstances require, a complete lymph node dissection should be performed to provide potential curative treatment to those affected. Moreover, according to the present findings, in case of the appearance of lung metastases the constancy of metastatic steroid hormone- and HER2 receptor expression, especially of the estrogen receptor, cannot always be assumed. Changes in comparison to the primary carcinoma appear in a relevant number of cases. Thus, the current metastatic receptor status should be evaluated obligatorily after pulmonary metastasectomy. Regarding the origin of pulmonary nodules of patients with history of breast cancer, their surgical resection with subsequent histopathological analysis can reliably differentiate between metastases, lung carcinoma or benign tumors. Altogether this facilitates specific and accurate treatment decisions. However, to identify patients with a limited and stable oligometastatic state of disease and to introduce optimal treatment, including surgical resection, an early, continuous, and also instrument-based follow-up is necessary. This matter is still only slightly taken into account, while the authors of the current guidelines refer to out of date studies, which have to be seen critically. As limitations of the present investigation, the retrospective study design, inconsistent evaluation of the primary receptor status, and also heterogeneity of postoperative medical therapy must be mentioned. In the future larger, multicentric, prospective, randomized trials are necessary to acquire further data, to conceivably continue to establish the pulmonary laser metastasectomy in multimodal therapy settings and also to determine the value of an extended follow-up
