Outcomes and prognostic factors of repeat pulmonary metastasectomy.

Information on prognostic factors after repeat pulmonary metastasectomy (PM) is limited, and outcomes after a third PM are not well documented. A single-institute retrospective study was conducted. Between 2000 and 2020, 68 patients underwent repeat PM for pulmonary metastases from various cancers. Outcomes and prognostic factors for the second PM and outcomes after the third PM were analysed. This study included 39 men and 29 women. The mean age at second PM was 53.2 years old. The primary tumours were soft tissue sarcoma in 24 patients, colorectal cancer in 19 and osteosarcoma in 10. The interval between the first PM procedure and detection of pulmonary metastasis after the first PM (months) was ≤12 in 37 patients and >12 in 31 patients. At the second PM, 20 patients underwent lobectomy or bilobectomy, and 48 underwent sublobar resection. Complete resection was achieved in 60 patients, and 52 patients experienced recurrence after the second PM. The 5-year relapse-free survival and overall survival rates after the second PM were 27% and 48%, respectively. Multivariable analysis revealed that the interval between the first PM and the subsequent detection of pulmonary metastasis (≤12 months) was a poor prognostic factor for both relapse-free survival and overall survival after the second PM. Seventeen patients underwent a third PM, 3 of whom achieved a 3-year disease-free survival. Patients with a period of >12 months between the first PM and the subsequent detection of pulmonary metastases showed favourable outcomes and are thus considered good candidates for second PM. A third PM may be beneficial for selected patients.

The role and benefit of minimally invasive repeat pulmonary metastasectomy: a narrative review

Surgical indication of pulmonary metastasis arising from osteosarcoma or soft tissue sarcoma.

Metastasectomy is often the local treatment for pulmonary metastases arising from osteosarcoma or soft tissue sarcoma. However, there have been few investigations on the outcomes of patients who undergo this procedure. In this study, we identified prognostic factors in patients with pulmonary metastases arising from osteosarcoma and soft tissue sarcoma to determine more appropriate eligibility criteria for metastasectomy. We retrospectively examined 37 patients who underwent metastasectomy of pulmonary nodules arising from osteosarcomas or soft tissue sarcomas at our institute between 2005 and 2020. Overall and recurrence-free survival intervals were determined using univariate and multivariate analyses. A tumor doubling time > 1month and a primary tumor histological type of osteosarcoma were independent predictors of longer overall survival on multivariate analysis (hazard ratios: 3.618 and 2.979, p = 0.00986 and 0.0373, respectively). Moreover, a > 1-month tumor doubling time and > 10-cm diameter of the primary tumor were independent predictors of longer recurrence-free survival (hazard ratios: 3.293 and 2.67, p = 0.0121 and 0.0134, respectively). Patients who underwent repeat pulmonary metastasectomy after complete resection of sarcoma-derived pulmonary metastases had significantly longer overall survival than those who did not (median: 5.91years vs. 0.81years, p < 0.0001). Tumor doubling time is a significant predictor of clinical outcomes in patients who undergo resection of pulmonary metastases originating from sarcomas. The surgical indication for this procedure should be decided carefully, particularly for patients with metastatic lesion doubling times ≤ 1month.

Outcome of Repeat Pulmonary Metastasectomy.

Pulmonary metastasectomy is a well-established contribution to the cure of oligometastatic cancers, but its exact effectiveness is poorly understood. Here we report the outcomes of repeat pulmonary metastasectomy from a multicenter trial. This retrospective study included patients who underwent re-do metastasectomies between January 2010 and December 2014. The exclusion criterion was metastasectomy without curative intent. We reviewed medical files of 621 consecutive patients who underwent initial pulmonary metastasectomy. Of those, 64 patients underwent repeat metastasectomies, and these patients were included in the analysis. All the 64 patients underwent a second metastasectomy, later 35 of them underwent a third metastasectomy, 12 underwent a fourth metastasectomy, and 6 underwent a fifth metastasectomy. The total number of re-do metastasectomies was 181. The median overall survival among the patients undergoing re-do metastasectomy was 66.0±3.8months. Three and 5-year survival rates were 82.3% and 63.3%, respectively. The 5-year survival rates were 63.3% after the first, 50.9% after the second, 74.4% after the third, 83.3% after the fourth, and 60.0% after the fifth metastasectomy. We conclude that at the current stage of knowledge, there is an indication for repeat re-do metastasectomy with curative intent.

Prognostic factors in pulmonary metastasectomy and efficacy of repeat pulmonary metastasectomy from colorectal cancer

BackgroundThe rate of pulmonary metastasectomy from colorectal cancer (CRC) has increased with recent advances in chemotherapy, diagnostic techniques, and surgical procedures. The purpose of this study was to investigate the prognostic factors for response to pulmonary metastasectomy and the efficacy of repeat pulmonary metastasectomy.MethodsThis study was a retrospective, single-institution study of 126 CRC patients who underwent pulmonary metastasectomy between 2000 and 2019 at the Gifu University Hospital.ResultsThe 3- and 5-year survival rates were 84.9% and 60.8%, respectively. Among the 126 patients, 26 (20.6%) underwent a second pulmonary metastasectomy for pulmonary recurrence after initial pulmonary metastasectomy. Univariate analysis of survival identified seven significant factors: (1) gender (p = 0.04), (2) past history of extra-thoracic metastasis (p = 0.04), (3) maximum tumor size (p = 0.002), (4) mediastinal lymph node metastasis (p = 0.02), (5) preoperative carcinoembryonic antigen (CEA) level (p = 0.01), (6) preoperative carbohydrate antigen 19-9 (CA19-9) level (p = 0.03), and (7) repeat pulmonary metastasectomy for pulmonary recurrence (p < 0.001). On multivariate analysis, only mediastinal lymph node metastasis (p = 0.02, risk ratio 8.206, 95% confidence interval (CI) 1.566–34.962) and repeat pulmonary metastasectomy for pulmonary recurrence (p < 0.001, risk ratio 0.054, 95% CI 0.010–0.202) were significant. Furthermore, in the evaluation of surgical outcomes, the safety of second pulmonary metastasectomy was almost the same as that of initial pulmonary metastasectomy.ConclusionsRepeat pulmonary metastasectomy is likely to be safe and effective for recurrent cases that meet the surgical criteria. However, mediastinal lymph node metastasis was a significant independent prognostic factor for worse overall survival.

A case of repeat resection for recurrent pulmonary metastasis from sebaceous gland carcinoma

BackgroundSebaceous gland carcinoma (SGC) of the eyelid is an aggressive malignant eyelid tumor, and it can metastasize to the regional lymph nodes and distant organs. There have been only a few reported cases of patients who underwent pulmonary metastasectomy for metastatic SGC. We herein report a patient who underwent repeat pulmonary metastasectomies for recurrent pulmonary metastases from SGC.Case presentationBilateral small pulmonary nodules were detected in a 59-year-old woman with a history of eyelid SGC. She underwent wide wedge resection of the left lower lobe, and the disease was diagnosed as pulmonary metastases from SGC. Six months after the first pulmonary resection, CT showed that the nodules of right S2 and S10 had increased in size, and three small nodules had newly appeared in the right lung. The patient therefore underwent six wide wedge resections of the right lung through thoracotomy. After that, she underwent pulmonary metastasectomy 2 times. Ninety months after the first pulmonary resection, the patient is doing well without disease.ConclusionsGiven that a long-term survival was ultimately achieved in the present case, repeat pulmonary metastasectomy may be beneficial for recurrent pulmonary metastasis from SGC.

Is Repeat Pulmonary Metastasectomy Indicated for Soft Tissue Sarcoma?

Because recurrence is high after pulmonary metastasectomy (PM) for soft tissue sarcoma (STS), repeat PM is commonly performed. Our objective was to define the selection criteria for repeat PM among patients experiencing recurrence and to identify factors associated with survival. We reviewed a prospectively maintained database of 539 patients undergoing PM for STS. Characteristics of the primary tumor, metastatic disease, treatment, and recurrence were examined. Multivariable Cox models were constructed to identify factors associated with the likelihood of operative selection after recurrence. Overall survival between patients with or without repeat PM was estimated using the Kaplan-Meier method, with prognostic factors identified using Cox models. Both analyses incorporated propensity score-matching weights. Factors associated with survival after repeat PM were assessed with multivariable Cox models among patients who underwent repeat PM. After initial PM, 63% of patients (n= 341) experienced pulmonary recurrence; 141 (41%) underwent repeat PM. Patients who were younger (p= 0.033) underwent minimally invasive resection at first PM (p= 0.041), had a longer disease-free interval after first PM (p= 0.009), were without extrapulmonary disease (p < 0.001), and had fewer nodules on recurrence (p < 0.001) were more likely to undergo repeat PM. Comparison between the repeat and non-repeat PM groups demonstrated an increased hazard of death among patients managed nonoperatively. Factors associated with an increased hazard of death after second PM included preoperative chemotherapy (p= 0.008) and R1/R2 metastasectomy (p < 0.001). Although operative selection occurs, when prognostic factors are controlled for, repeat PM for STS remains independently associated with prolonged overall survival.

Lung Metastasectomy in Pulmonary Metastatic Colorectal Carcinoma

Patients with colorectal cancer are often affected by liver and lung metastases. Besides systemic therapies, lung metastasectomy is a suitable treatment option after complete resection of primary colorectal carcinoma and even concomitant liver metastases. We have performed a systematical literature research of all studies published after 01. 01. 2010. Studies reporting on at least 100 patients undergoing lung metastasectomy after 01. 01. 2000 have been included in our final analysis. Operative data, survival data and prognostic factors have been extracted. Eleven study cohorts reporting on 2,891 patients could be included in the final analysis. Complete resection could be achieved in most cases and thoracic surgeons preferred subsegmental resections. Pathological examination revealed thoracic lymph node involvement in 2.3 to 18.2% of patients. The postoperative mortality varied from 0 to 0.5%. The median follow up ranged between 27.5 and 65.1 months. Pulmonary metastasectomy resulted in 5-year survival rates of 53 to 75.5% and 5-year progression-free survival rates of 33 to 50.9%. Intrathoracic recurrence occurred in 25.2 to 42.9% of patients with complete resection and five-year survival rates ranged from 49 to 75.5% after repeat pulmonary metastasectomy. Analysis of prognostic factors revealed that number, size and distribution of lung metastases are minor important prognostic factors. Moreover, current data suggest disadvantageous post-metastasectomy survival for patients with elevated pre-metastasectomy serum CEA level or intrathoracic lymph node metastases in comparison with the control groups. Nevertheless, even in these patients, lung metastasectomy might be a beneficial procedure. In patients with colorectal cancer and resectable isolated lung or combined liver and lung metastases pulmonary resection should be the treatment of choice. Pulmonary metastasectomy should be combined with thoracic lymph node resection to remove potential lymph node metastases. Repeat metastasectomy should be offered to patients suffering from isolated intrathoracic recurrence.

Repeat pulmonary resection for recurrent lung metastases from colorectal cancer: an analysis of prognostic factors

The purpose of this study was to investigate the prognostic factors for repeat lung metastasectomy in patients with colorectal cancer, which may be clinically helpful in defining a subset of patients who are most likely to benefit from repeat lung metastasectomy. In total, 138 patients underwent complete lung resection for the first time due to metastases of colorectal cancer between January 2004 and December 2013 at Fujita Health University School of Medicine. Among them, 33 underwent repeat pulmonary metastasectomy for lung tumour recurrence. Kaplan-Meier survival curves and log-rank tests were used to analyse the survival rates. No patient died as a direct result of surgery, and all patients were discharged after the repeat pulmonary metastasectomy. The 5-year survival rate after the initial pulmonary resection of the 33 patients who underwent repeat lung resection was 64%, which was not significantly different from that of the 105 patients who did not undergo repeat lung resection (5-year survival rate, 61%; P = 0.779). Univariate analysis identified only one significant prognostic factor: preoperative serum carcinoembryonic antigen (CEA) level (P = 0.002). The 5-year survival rates of patients with high preoperative CEA levels and normal CEA levels after repeat metastasectomy were significantly different at 47 and 90%, respectively. Prethoracotomy serum CEA levels affect survival rates after repeat pulmonary resection. The preoperative assessment of serum CEA levels before repeat metastasectomy is important when considering repeat pulmonary resection, and prethoracotomy CEA levels should be taken into account when selecting patients for repeat lung resection.

Surgical and non-surgical management of repeat pulmonary metastasis from sarcoma following first pulmonary metastasectomy.

Although repeat pulmonary metastasectomy for sarcoma is not uncommon and associated with a favorable survival in select patients, there is a paucity of data on the demographics and tumor characteristics of patients with repeat pulmonary metastasis following complete resection of pulmonary metastases from osteogenic or soft tissue sarcoma. A retrospective chart review was performed to identify patients with isolated repeat pulmonary metastasis after complete resection of pulmonary metastases from sarcoma at Kyoto University Hospital between January 1990 and December 2014. Isolated pulmonary metastasis was defined as limited to presumable pulmonary metastasis according to the follow-up radiologic workup. Thirty-five patients were identified to have repeat pulmonary metastasis. Thirty patients underwent attempted repeat pulmonary metastasectomy (including 21 undergoing documented complete resection and 7 undergoing documented incomplete or aborted resections). Five patients received non-surgical management. The median follow-up period was 16months (range 1-234) from repeat pulmonary metastasis. The five-year overall survival of the whole patient cohort and those undergoing repeat pulmonary metastasectomy were 37.6 and 41.1%, respectively, from repeat pulmonary metastasis. A majority of patients with repeat pulmonary metastasis from sarcoma undergo repeat metastasectomy, which is associated with favorable survival outcomes. However, a greater accumulation of data on non-surgically managed patients is needed as such information is currently limited available.

Pulmonary metastasectomy: role of pulmonary metastasectomy and type of surgery.

Patients with untreated metastatic disease have a less than 5 % to 10 % 5-year survival, and for the patient who has metastatic disease isolated to the lungs, pulmonary metastasectomy remains the best hope for cure. Pulmonary metastasectomy has been performed for decades. However, despite hundreds of studies spanning several decades, randomized control data in support of pulmonary metastasectomy is still lacking, and the evidence upon which we base this commonly accepted surgical practice is for the most part weak. While well-accepted surgical selection criteria exist, controversies related to pulmonary metastasectomy abound. Unanswered and clearly debatable are questions related to: optimal preoperative imaging, if mediastinal staging should be performed and if so when, is video-assisted thoracic surgery (VATS) equivalent to open thoracotomy, is finger palpation of the lung mandatory, is repeat pulmonary metastasectomy justified, and what is the interrelationship of pulmonary metastasectomy to other treatments. Current practice to the surgical approach to pulmonary metastasectomy remains quite variable.

Repeated Resection for Pulmonary Metastatic Hepatocellular Carcinoma after Liver Transplantation— Case Reports and a Proposal of Negative Predictors for the Recurrence after the Operation

Background: Orthotropic liver transplantation (OLTx) is recognized as a radical therapy for unresectable hepatocellular carcinoma (HCC) without distant metastasis. Although the outcome depends on distant recurrence of HCC, the predictors for recurrence after repeat resection are unknown. Case 1: A 52-year-old man, who had suffered from hepatitis B and underwent repeat local ablation therapies since 50 years old, underwent living-donor OLTx because of multiple HCC recurrence with tumor marker (TM) elevation but without distant metastasis. Histopathological diagnosis was moderately differentiated HCC. After the operation, he got TM normalization and was managed with cyclosporine A, without rejection. Although he underwent adjuvant chemotherapy, a pulmonary metastasis was found 1 year after the OLTx. He underwent wedge resection of the lung using video-assisted thoracoscopic surgery (VATS). Half a year after the operation, a recurrence was found in the transplanted liver with TM elevation. While a local ablation therapy was performed, TM was not normalized and new recurrence was found at the hilum of the right lung. Right upper sleeve lobectomy was performed, but he developed multiple recurrences, and died 4 months after the last operation. Case 2: A 32-year-old man, who has suffered from multiple HCC with hepatitis B and underwent hepatic resection and local ablation therapies since 28 years old, underwent living-donor OLTx because of multiple HCC recurrence without distant metastasis. Histopathological diagnosis was moderately differentiated HCC. He was managed using tacrolimus without rejection. Three years after the OLTx, a pulmonary recurrence was found without TM elevation. He underwent wedge resection using VATS. Four year after the last operation, a small recurrence was identified in the right lung without TM elevation, again. Wedge resection using VATS was performed. At the final follow-up visit, 3 years after the last operation, the patient was disease free with normal TM level. Comments: The long survivor without re-recurrence matched only few factors with negative predictors for recurrence after OLTx for HCC, while the other case had almost all factors present. The predictors may be useful also for the patients of the repeat pulmonary metastasectomy after OLTx for HCC.

Repeat Resection of Pulmonary Metastasis Is Beneficial for Patients with Colorectal Carcinoma

The role for repeat pulmonary metastasectomy for colorectal carcinoma has not been well defined. To identify the class of patients who benefit from pulmonary resection of recurrent pulmonary metastases, we herein reviewed our institutional experience. Between 1990 and 2007, 84 patients with pulmonary metastases from colorectal carcinomas underwent complete pulmonary resection, and 22 of them (26%) later underwent complete resection for repeat pulmonary metastasis. Various perioperative variables were investigated retrospectively in these patients to confirm a role for repeat metastasectomy and analyze prognostic factors after repeat pulmonary metastasectomy. Overall survival and disease-free survival after repeat pulmonary metastasectomy were, respectively, 61 and 32% at 5 years. On univariate analysis, male gender and less than 1 year of disease-free status after the first pulmonary metastasectomy demonstrated significantly adverse overall survival (p = 0.01 and p = 0.009, respectively). Elevated preoperative serum carcinoembryonic antigen (CEA) level and maximum tumor size larger than 3 cm were also significantly adverse prognostic factors for disease-free survival (p = 0.03 and p = 0.04, respectively). The overall survival curve after repeat pulmonary metastasectomy was almost identical with that after complete resection of the first pulmonary metastasis. Patients with more than 1 year of disease-free status after the first pulmonary metastasectomy demonstrated a significantly better overall survival. Normal preoperative serum CEA level and maximum tumor size <3 cm were significantly adverse prognostic factors for disease-free survival. Our data imply that repeat pulmonary metastasectomy might be beneficial as it can salvage a subset of patients with colorectal carcinoma who retain favorable prognostic determinants.

Repeat resection of pulmonary metastasis is beneficial for patients with osteosarcoma of the extremities

Pulmonary metastasectomy in osteosarcoma can lead to long-term survival, but the role for repeat pulmonary metastasectomy is undefined. To confirm the value of repeat pulmonary resection of recurrent pulmonary metastases, we herein reviewed our institutional experience. Between 1989 and 2007, 25 patients with pulmonary metastases from osteosarcomas of the extremities underwent pulmonary resection, and 14 patients underwent repeat pulmonary metastasectomy. Ten of 14 patients underwent complete resection. Various perioperative variables were investigated retrospectively in these patients to confirm a role for repeat metastasectomy and analyze prognostic factors for overall survival (OS) after repeat pulmonary metastasectomy. OS rate after repeat pulmonary metastasectomy was 43% at two years and 19% at five years. On multivariate analysis, patients with complete resection presented significantly favorable OS (P=0.02). Interestingly enough, survival curve of patients with complete resection after the first pulmonary metastasectomy was almost the same as that of patients with complete resection after the second pulmonary metastasectomy. In conclusion, patients with complete resection for recurrent pulmonary metastasis show a significantly better prognosis after repeat pulmonary metastasectomy. Our data imply that repeat pulmonary metastasectomy might be beneficial because it can salvage a subset of patients with osteosarcoma who retain favorable prognostic determinants.

Pulmonary metastasectomy—A single institution experience

18505 Background: Resection of pulmonary metastases is a common procedure as part of the multidisciplinary management of a patient with metastatic disease confined to the lung. It is being utilized in a range of cancers including soft tissue sarcoma, renal cell carcinoma and colorectal cancer. Methods: We present twenty-one cases of metastatic cancer treated with pulmonary metastasectomy, identified on retrospective analysis of case files, over a period from 1994 to 2007. Results: Twenty-one cases were identified in total. The primary lesion was colorectal adenocarcinoma in 5 cases, head and neck squamous cell carcinoma in 5 cases, osteogenic sarcoma in 3 cases, melanoma in 2 cases, uterine myosarcoma in 2 cases, synovial sarcoma in 2 cases, adenocarcinoma of the ampulla and in 1 case and non-seminomatous germ cell tumor in 1 case. 57% of patients were female. The median disease free interval, from initial diagnosis to development of pulmonary metastases, was 34 months (range 7 mths to 11yrs). The median age at surgery was 53 yrs (range 20-75 yrs). 6 patients underwent repeat pulmonary metastasectomy for recurrent pulmonary disease. Two patients had both liver and pulmonary metastases resected. The median follow-up from date of pulmonary resection was 36 months (range 1 month-104 months). Three years post metastasectomy, 55% of patients were alive. Conclusions: This series illustrates the evolving role of pulmonary metastasectomy in the management of patients with metastatic cancer. Advances in imaging have led to the identification of small, potentially resectable lesions. New systemic therapies have led to down-staging of lesions, thus, pulmonary metastasectomy is increasingly an option in a broadening range of cancers. A survival advantage for pulmonary metastasectomy has been shown in several published series. However, there are no randomized prospective trials examining the role of metastasectomy and this remains a procedure in highly selected patients in a multi disciplinary setting. No significant financial relationships to disclose.
