Is salvage surgery for recurrent non-small-cell lung cancer after definitive non-operative therapy associated with reasonable survival?

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether salvage pulmonary resection is possible and worthwhile for patients with recurrence of non-small-cell lung cancer (NSCLC) after prior definitive non-operative therapy. A total of nine reports were identified using the reported search, of which four represented the best available evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. All studies were retrospective. In total, 48 pulmonary salvage resections were performed in 47 patients after prior definitive radiation, chemoradiation or stereotactic body radiation therapy, of which 28 were lobectomies (including 1 sleeve lobectomy), 12 pneumonectomies, 4 bilobectomies and 4 sublobar resections (2 segmentectomies and 2 wedge resections). Postoperative complications ranged from 0 to 58% (mean from four studies 42.5%). Only one study reported any mortality (4%), the other three had zero mortality. Median postoperative survival was reported in two studies and ranged from 9 to 30 months. Experience with salvage lung resection for locally recurrent NSCLC, after prior definitive non-surgical treatment, remains limited. Therefore, this analysis was based on only 48 resections in 47 patients from four retrospective studies. Nevertheless, the published data suggest that salvage lung surgery for recurrent, previously non-operatively managed non-small-cell lung cancer is a worthwhile treatment option with good survival, acceptable morbidity and low mortality.

Spontaneous Pneumothorax due to Ectopic Deciduosis: A Case Report.

This report presents a 20-week pregnant 38-year-old woman with right-sided pneumothorax due to pulmonary deciduosis. Initial pleural drainage was ineffective. Video-assisted thoracoscopy revealed areas of consolidation within the lung parenchyma. A wedge resection with partial pleurectomy was performed. Histopathological examination showed subpleural decidual implants. The patient made a full recovery and was discharged on day 5. Videoscopic inspection of the lung parenchyma and pleura with resection of decidual foci is the recommended treatment for pneumothorax in pregnant women with pleuropulmonary deciduosis in whom classical pleural drainage is ineffective.

Forty-Two Years' Experience with Pulmonary Resections of Metastases from Colorectal Cancer

Background Pulmonary metastasectomy is a commonly performed surgery in patients with controlled metastatic colorectal cancer (CRC). We reviewed our long-term single institution experience with lung resections for colorectal metastases to assess the factors influencing patient survival. Materials and Methods A cohort of 220 patients (138 men and 82 women; median age, 59 years) who underwent complete pulmonary metastasectomy for CRC with curative intent between 1972 and 2014 was retrospectively analyzed. The impact of factors related to primary tumor, metastases, and associated therapy on patient survival was assessed. Results Two postoperative inhospital deaths occurred. The median interoperative interval was 26 months. The overall 5-year survival rate after pulmonary metastasectomy was 49.4%. In univariable analysis, bilateral pulmonary metastases (log rank p = 0.02), multiple metastases (log rank p = 0.005), and stage IV UICC (the International Union Against Cancer) CRC at the time of initial presentation (log rank p = 0.008) were significantly associated with poor outcome. Multivariable Cox analysis demonstrated that stage IV CRC (p = 0.02) and multiple metastases (p = 0.0019) were statistically significant predictors of survival after the pulmonary metastasectomy. There was no significant difference in survival between patients with high versus low preoperative carcinoembryonic antigen serum level (p = 0.149), high versus low preoperative carbohydrate antigen 19-9 serum level (p = 0.291), and primary tumor location in rectum versus colon (p = 0.845). Conclusion Patients with unilateral metastasis and stages I to III primary tumor benefited most from pulmonary metastasectomy for CRC.

Long-Term Survival after Salvage Surgery for Local Failure after Definitive Chemoradiation Therapy for Locally Advanced Non-small Cell Lung Cancer

Background The incidence of local failure and residual tumor after definitive chemoradiation therapy (dCRT) for locally advanced non‐small‐cell lung cancer remains high, irrespective of applied radiation dose (>59 Gy). So‐called salvage surgery has been suggested as a feasible treatment option after failure of definitive chemoradiation for locally advanced non‐small cell lung cancer (NSCLC). Experience with salvage lung surgery (SLS) is limited, and long‐term survival is rarely reported. Patient selection criteria for surgical lung salvage are not defined. The aim of this study was to assess postoperative survival and perioperative morbidity/mortality to identify prognostic factors and to define patient selection criteria. Patients and Methods Records of 13 consecutive patients with locally advanced NSCLC, who underwent SLS at a single institution between March 2011 and November 2016, were reviewed. Descriptive statistics were applied for patient characteristics and surgical and oncological outcome. Survival rates were calculated using the Kaplan‐Meier method and were compared with the long‐rank test. Results All patients initially received curative‐intent definitive chemoradiation with median radiation doses of 66 Gy (range 59.4–72) and concurrent platinum‐based chemotherapy. Clinical tumor stage before definitive chemoradiation was IIIA in 9, IIIB in 3, IV in 1 patients. Median interval between definitive chemoradiation and salvage surgery was 6.7 months. Perioperative morbidity and 30‐days‐mortality was 38% and 7.7%, respectively. The median postoperative survival and estimated 5‐year survival rate were 29.7 months and 46%, respectively. Conclusion SLS in patients with locally advanced non‐small cell lung surgery following dCRT is feasible, prolongs long‐term survival and allows local tumor control. Selection criteria remain undefined and patients should be considered surgical candidates during multidisciplinary team conference.

Combined Clagett procedure, negative pressure therapy, and thoracomyoplasty for treatment of late-onset postpneumonectomy empyema necessitatis

Late-onset post-pneumonectomy empyema necessitatis can occur many years after the surgery and is a life-threatening condition. A 58-year-old male presented with empyema necessitatis 18 years after undergoing pneumonectomy. He was successfully treated with a modified two-stage Clagett procedure and ambulatory negative pressure as the bridge between the stages. The 72-month follow-up was uneventful. The complete obliteration of the rigid and wide residual postpneumonectomy cavity was necessary to avoid re-recurrence of the infection.

Videothorakoskopisches Sympathikus-Clipping bei einem Patienten mit Lobus venae azygos. Intraoperatives Management zur Vermeidung von potenziellen Komplikationen

INTRODUCTION Sympathetic clipping in the presence of an azygos lobe is a rare combination. Anatomical relations between the sympathetic trunk and the mesoazygos impede surgical handling and can be associated with potential complications. INDICATION We report the case of a 25-year old woman with grade III palmoplantar and axillary hyperhidrosis with azygos lobe incidentally found on preoperative chest X-ray. METHOD Our intraoperative video shows a step-by-step approach to the sympathetic trunk in the presence of the azygos lobe, involving thoracoscopic looping and precise clip application onto the sympathetic trunk. Video-assisted reposition and expansion of the accessory lobe to avoid potential complications have been demonstrated. CONCLUSION Videothoracoscopic sympathetic clipping in patients with lobus azygos is technically challenging. Potential complications can be avoided by coordinated surgical management.

Pathologic complete response after induction therapy—the role of surgery in stage IIIA/B locally advanced non-small cell lung cancer

Background Pathologic complete response (pCR) is dominant prognostic factor determining favorable outcome in locally advanced non-small cell lung cancer (NSCLC) after induction therapy (IT). There is no non-operative diagnostics that adequately estimates the pCR. Aim of this retrospective study was to assess the correlation between clinical and pathological factors in patients with pCR. Methods Twenty-five patients with pCR after curative lung resection following IT were assessed using univariate and multivariate Cox regression and descriptive analysis. The survival rate was estimated by Kaplan-Meier method. Results The IT included chemoradiation with median doses of 50.4 Gy (range, 45-59.4 Gy) combined with platinum-based chemotherapy in 23 patients (92%) and induction platinum-based chemotherapy in 2 patients (8%). Clinical tumor stage before IT was IIIA in 21, IIIB in 4 patients. Mean interval between IT and surgery was 8.1±3.0 weeks. Perioperative morbidity and 30-day mortality was 32% and 4%, respectively. There was no significant correlation of pCR and different clinical and pathological factors. The estimated 5-year long-term survival (LTS) and progressive-free survival (PFS) was 57% and 54%, respectively. The median LTS and PFS was not reached. Conclusions pCR in patients with locally advanced NSCLC following IT is an independent prognostic factor, without correlation with pathological and clinical factors. Non-operative accurate assessment of pCR is currently impossible. Surgical resection enables secure identification of pCR and might improve the patient stratification for additive therapy.

Sternal resection and reconstruction for secondary malignancies

Background Limited data on sternal and/or anterior chest wall resections for secondary malignancies exist. The purpose of this study was to examine the perioperative outcomes and postoperative overall survival (OS) in patients who underwent sternal and/or anterior chest wall resections for secondary sternal tumors (SSTs). Methods A retrospective analysis of all patients who underwent resection of SSTs at single institution between 2000 and 2016 has been performed. OS was estimated using the Kaplan-Meier method. Results Ten patients underwent sternal and/or anterior chest wall resection for SSTs with curative (70%) or palliative (30%) intent. Two (20%) patients underwent complete and 8 (80%) partial sternal and/or anterior chest wall resection. There were no perioperative deaths, major complications occurred in 3 (30%) patients. Tumor resection was complete (R0) in 5 (50%) patients. The 5-year OS rate was 40%. No OS difference in R0 vs. R1 resections was observed. Conclusions Sternal and/or anterior chest wall resections for SSTs can be performed with low morbidity and mortality. Complete SST resection does not assure favorable OS. Sternal resections can be considered palliative treatment option in patients with stable stage IV disease with isolated sternal involvement.
