3502 Background: This current study was an open, prospective and nonrandomized phase II study, which critically evaluated the prognostic parameters for local disease-free survival (DFS) and overall survival (OS) in patients who underwent percutaneous radiofrequency ablation (RFA) for inoperable colorectal pulmonary metastases (CRPM). Methods: The inclusion criteria were patients who had inoperable CRPM, due to number, distribution, poor performance status or patients’ refusal to accept surgery. The exclusion criteria were lesions > 6 per hemithorax; diameter of metastases > 5 cm; bleeding diathesis; and/or significantly compromised lung function. All patients underwent percutaneous RFA with a radiological clear margin of at least 2 cm. The end-points of this study were local DFS and OS, determined from the time of RFA intervention. Ten clinical and six treatment-related prognostic parameters were assessed in univariate and multivariate analyses. All patients were reviewed at one week, one month and every three months thereafter with chest CT. Fifty-five patients entered into the study. The follow-up was complete and the median follow-up was 24 months (6 to 40). Results: The median local DFS was not reached and 2-year local DFS was 57%. Univariate analysis demonstrated that largest size of lung metastasis, location of lung metastases, post-RFA CEA at 1 month and 3 months were significant for local DFS. In multivariate analysis, largest size of lung metastasis of ≤ 3 cm and post-RFA CEA of ≤ 5 ng/ml at 1 month were independently associated with an improved local DFS. The median OS was 33 months (4 to 40), with 1-, 2-, and 3-year survival of 85%, 64% and 46%, respectively. Univariate analysis demonstrated that interval between the diagnoses of colorectal cancer and pulmonary metastasis; largest size of lung metastasis and location of lung metastases were significant for OS. In multivariate analysis, only size of lung metastasis of ≤ 3 cm was independently associated with an improved OS. Conclusions: Percutaneous RFA of inoperable CRPM may have a useful role in patients with a lesion of ≤ 3 cm. No significant financial relationships to disclose.

141 Background: Radiofrequency ablation (RFA) has been increasingly used for the treatment of pulmonary metastases from several types of malignancies. Methods: A retrospective analysis was performed for the safety and efficacy of percutaneous RFA in patients with metastatic colorectal cancer between October 2016 and June 2019 as well as assessing prognostic factors of local tumor control. Results: RFA was carried out for 48 lung metastases in 31 consecutive colorectal cancer patients. Male was 17 patients (55%), and the median age at RFA was 61 years (range, 42-81). The mean diameter of metastases targeted for RFA was 12 mm (range, 4-32), and 17 tumors (35%) were located in a sub-pleural or deep position. Although five cases (10%) were failed due to immediate complications, there was no procedure-related death. In terms of immediate complication, a total of 12 cases (25%) had events including nine pneumothorax (percutaneous drain in four), one pleural effusion, and two hemoptysis (ICU care in one). Delayed complications were lung abscess and diaphragm injury in each one patient, respectively. At the time of analysis, the median follow-up duration from RFA was 12.0 months (interquartile range, 6.5-23.1). Only two patients (6%) died of disease progression, and 3-year overall survival rate was 85.5% (95% CI, 75.5-95.5). RFA site progression was observed in 11 patients (23%), and 1-year and 2-year progression-free survival rates were 71.5% (95% CI, 58.7-84.3) and 56.6% (95% CI, 42.6-70.6), respectively. Multivariate analysis showed that extra-pulmonary progression (hazard ratio 17.49; p = 0.023) was only one independent prognostic factor associated with RFA site progression after adjusting for confounding factors including sex, age, performance, tumor size, location, contact with the vessel, last chemotherapy response, and duration. Conclusions: RFA is a comparatively safe and effective option for the treatment of small-sized lung metastases; however, the control of extra-pulmonary metastases should be accompanied for effective local control.

Introduction. Survival outcomes in patients with unresectable colorectal cancer (CRC) liver metastasis treated by radiofrequency ablation (RFA) combined with systemic chemotherapy and correlation with potential prognostic factors were investigated. Material and Methods. A retrospective cohort study was conducted on 61 CRC patients with unresectable liver metastasis who underwent liver tumor-directed percutaneous RFA combined with conventional systemic chemotherapy between October 2013 and September 2018. Survival analyses were conducted using the Kaplan-Meier method, and the log-rank test was used to characterize differences in the median survival time and the 1-year, 3-year, and 5-year overall survival rates of subgroups to identify prognostic factors. Results. Median overall survival and progression-free survival of all patients were 32 and 14 months, respectively. The cumulative survival rates at 1-, 3-, and 5-years were 93.2%; 44.5%, and 38.2%, respectively. Univariate analysis revealed that pre-RFA serum CEA levels, Eastern Cooperative Oncology Group (ECOG) status, number of liver lesions, the size of the largest lesion, and the total lesion size were prognostic factors. However, multivariate analysis demonstrated that only the number of liver lesions and the size of the largest lesion were independent prognostic factors for survival. Conclusion. RFA plus systemic chemotherapy provides an encouraging survival outcome for patients with unresectable CRC liver metastasis. Multivariate analysis demonstrated that the number and size of liver metastatic lesions are independent prognostic factors for survival.

e14533 Background: To determine impact of modern chemotherapy regimens after pulmonary metastasectomy from colorectal cancer (CRC). Methods: A total of 122 consecutive patients who curatively resected for pulmonary metastases of CRC in eleven oncology centers were retrospectively analysed between January 2000 and April 2012. Results: Of 122 patients, 108 who received chemotherapy with fluoropyrimidine-based (n = 12), irinotecan-based (n = 56) and oxaliplatin-based (n = 40) combinations were analyzed. Among these, 52 patients received bevacizumab (BEV) while 56 did not (NoBEV). With a median follow-up of 14 months after metastasectomy, median recurrence-free survival (RFS) was 17 months, overall survival (OS) was not reached. Three and 5-years OS rates were 66% and 53%, respectively. There was no significant difference among cytotoxic regimens in respect to RFS and OS. Similarly, no significant difference was seen between BEV and NoBEV arms in respect to OS and RFS. In univariate analysis prior liver metastasectomy (p = 0.045), positive pulmonary margin (p = 0.028), disease-free interval < 12 months (p = 0.013), and KRAS mutation (0.009) were negative significant prognostic for RFS. Thoracic pathological lymphatic involvement (p = 0.006) and higher prethoracotomy carcinoembryonic antigen (p = 0.038) were negative significant prognostic for OS. In multivariate analysis, positive pulmonary margin was the only negative independent prognostic for RFS, while thoracic lymphatic involvement was the only negative independent prognostic for OS. Conclusions: Chemotherapy type and addition of bevacizumab have no impact on both RFS and OS in the adjuvant setting following complete resection of colorectal pulmonary metastases.

757 Background: Surgical resection of liver metastases provides a significant survival benefit, and potential for cure, in selected patients with metastatic colorectal cancer. There are very limited data on resection of lung metastases in patients with colorectal lung metastases. We evaluated outcomes after resection of lung metastases in patients with colorectal cancer. Methods: We conducted a retrospective cohort study in patients who underwent resection of pulmonary metastases between 2/2006 and 6/2013 at Cleveland Clinic. Clinical, pathologic, and outcome data were collected by electronic medical records review. Overall survival (OS) as the primary endpoint was summarized by Kaplan-Meier method and analyzed by log-rank tests. Results: The study population comprised 32 patients. Overall, 20 patients were male and median age at diagnosis of lung metastasis was 60.0 years (range 30.4-81.9). All patients had resection of primary tumor. Eleven patients had preoperative chemotherapy and 12 had adjuvant chemotherapy. Patients with unilateral metastases comprised the majority of patients (N = 22, 68.8%); 59% (N = 19) had a solitary metastasis. The median diameter of lung metastases was 20.5 mm (range 7.0 -50.0). Ten patients had concurrent liver metastases, eight of whom had liver resection as well. Overall, 31% (10/32) of patients recurred, with 50% (16/32) of recurrences in the lung, and 28% died. Estimated median OS was 55.0 months. Estimated 5-year OS was 32% ± 17%. Higher CEA level ( ≥ 4.5 ng/mL) at the time of diagnosis of lung metastasis was associated with worsened OS (p = 0.026). Other potential prognostic factors, such as laterality, number of lung metastases, and extrapulmonary lesions, were not associated with overall survival in this study population. Conclusions: Our study showed resection of lung metastases in select patients with colorectal cancer can be associated with prolonged survival in the range seen with resection of liver metastases. Higher CEA level at time of diagnosis of lung metastasis is associated with poorer prognosis. More data are necessary to identify approaches to patient selection in the metastatic colorectal setting.

Background: Consensus guidelines of the European Society for Medical Oncology (ESMO) (2016) provided recommendations for the management of lung metastases. Thermal ablation appears as a tool in the management of these secondary pulmonary lesions, in the same manner as surgical resection or stereotactic ablative radiotherapy (SABR). Methods: Indications, technical considerations, oncological outcomes such as survival (OS) or local control (LC), prognostic factors and complications of thermal ablation in colorectal cancer lung metastases were reviewed and put into perspective with results of surgery and SABR. Results: LC rates varied from 62 to 91%, with size of the metastasis (<2 cm), proximity to the bronchi or vessels, and size of ablation margins (>5 mm) as predictive factors of LC. Median OS varied between 33 and 68 months. Pulmonary free disease interval <12 months, positive carcinoembryonic antigen, absence of neoadjuvant chemotherapy and uncontrolled extra-pulmonary metastases were poor prognostic factors for OS. While chest drainage for less than 48 h was required in 13 to 47% of treatments, major complications were rare. Conclusions: Thermal ablation of a selected subpopulation of patients with colorectal cancer lung metastases is safe and can provide excellent LC and delay systemic chemotherapy.

Abstract INTRODUCTION Renal cell carcinoma (RCC) represents 3% of overall malignant neoplasms in adults. However, its aetiology has not been clearly established. Although surgery represents the cornerstone in treatment, recurrence postoperative rates are around 20-30%, what implies prognostic factors search must be mandatory in order to help to plan de follow-up and the different adjuvant therapy possibilities available in case they were necessary. MATERIAL AND METHODS A retrospective observational study was carried out in 110 patients who underwent radical nephrectomy between 2004 and 2018, with the aim of identifying possible prognostic factors of recurrence of RCC after these surgeries. Preoperative data (epidemiological, comorbidities and laboratory tests), surgical, pathological and variables related to follow-up were taken into account. A univariate and multivariate analysis were performed, using chi-square test and logistic regression, respectively. RESULTS The median follow-up time was 53.5 months (SD = 35.8), time in which 19 patients had a recurrence of RCC after radical nephrectomy (17.2%). Histopathological items such as the surgical piece size, the nodal and microvascular invasion, the renal sinus invasion and the presence of necrosis in the surgical piece were associated with RCC recurrence in the univariate analysis, while only the presence of necrosis in the surgical piece showed a significant result in the multivariate analysis (p = 0.004). CONCLUSIONS Histopathological analysis, highlighting the presence of necrosis in the histological sample, was proved to be the main risk factor of RCC recurrence.

Objective. The aim of our research is to explore the clinical efficacy and safety of CT-guided percutaneous microwave ablation (MWA) for the treatment of lung metastasis from colorectal cancer. Materials and Methods. CT-guided percutaneous MWA was performed in 22 patients (male 14, female 8, mean age: 56.05 ± 12.32 years) with a total of 36 lung metastatic lesions from colorectal cancer between February 2014 and May 2017. Clinical data were retrospectively analyzed with respect to the efficacy, safety, and outcome. Results. Of the 36 lesions, 34 lesions (94.4%) reduced obviously with small cavitations or fibrous stripes formed and had no evidence of recurrence during follow-up. The volume of the other 2 lesions demonstrated local progression after 6 months by follow-up CT. The primary complications included pneumothorax (28%), chest pain (21%), and fever (5%). These symptoms and signs were obviously relieved or disappeared after several-day conservative treatment. The mean follow-up of the patients was 25.54 ± 12.58 months (range 2–41 months). The estimated progression-free survival rate was 94.4%. Conclusion. Our results demonstrate that CT-guided percutaneous MWA appears to be an effective, reliable, and minimally invasive method for the treatment of lung metastasis from colorectal cancer. This trial is registered with ChiCTR-ORC-17012904.
