Splenic Enlargement

Abstract Background: Conversion chemotherapy may downsize unresectable colorectal liver metastases (CRLMs), but may cause liver injury and splenic enlargement. The effect of preoperative chemotherapy on liver regeneration after liver resection remains undetermined. The aim of this study was to examine whether splenic enlargement induced by preoperative chemotherapy is an indicator to identify high-risk patients for impaired liver regeneration and liver dysfunction after resection. Methods: We retrospectively reviewed 118 Japanese patients with CRLMs. Fifty one patients had conversion chemotherapy. The other 67 patients underwent upfront liver resection. We clarified effects of conversion chemotherapy on splenic volume, liver function, and postoperative liver regeneration. Perioperative outcome was also analyzed. Results: A ratio of the splenic volume before and after chemotherapy (SP index) in the oxaliplatin-based chemotherapy group was significantly greater than other chemotherapy groups after 9 or more chemotherapy cycles. Patients whose SP index was 1.2 or more had significantly higher indocyanine green retention rate at 15 min (ICG-R15) than patients without chemotherapy. Analyses of covariance showed liver regeneration rate after resection was decreased in patients whose SP index was 1.2 or more. The incidence of postoperative liver dysfunction in patients whose SP index was 1.2 or more was significantly greater than patients without chemotherapy. Multivariate analysis showed SP index was a significant predictive factor of impaired liver regeneration. Conclusions: Splenic enlargement induced by preoperative chemotherapy was a useful indicator for impaired liver regeneration after resection and a decision-making tool of treatment strategy for unresectable CRLMs.

Objective: To investigate the functional liver regeneration after chemotherapy and liver resection for colorectal liver metastases (CRLM). Background/Purpose: Preoperative chemotherapy followed by liver resection for CRLM has been increasing; however, its negative impact on liver regeneration remains unknown. Methods: From January 2009 to December 2013, we enrolled 40 selected patients who underwent major hepatectomy without viral hepatitis and severe liver fibrosis. CRLM patients with preoperative chemotherapy (CT-CRLM group, n = 12) and patients without preoperative chemotherapy (control group, n = 28) were evaluated. Liver volume (LV) and functional liver volume (FLV) was assessed using Tc-99m–labeled galactosyl human serum albumin (99mTc-GSA) scintigraphy, single-photon emission computed tomography (SPECT), CT-fused images. Preoperative, future remnant liver, and post 1-month values were compared. Results: Median course of preoperative chemotherapy was 8 (range: 6–16). Preoperative background factors were almost identical including resection rate and functional resection rate. In the CT-CRLM group and in the control group, the percentage increases in LV were 39.3% ± 29.0% and 23.2% ± 23.5% (P = 0.037), and FLV were 79.4% ± 43.1% and 57.0% ± 33.4% (P = 0.417), respectively; absolute differences in LV were 216.2 ± 155.7 cm3 and 148.7 ± 134.7 cm3 (P = 0.086) and FLV were 19.4% ± 8.5%/m2 and 17.4% ± 7.9%/m2 (P = 0.235), respectively. We found no obvious tendency for negative influence on liver functional regeneration by the preoperative regimens for CRLM. Conclusions: Several courses of preoperative chemotherapy may not affect functional liver regeneration for CRLM patients after major hepatectomy.

The Impact

365 Background: Treatment for borderline colorectal liver metastases (CLM) is often started with chemotherapy. However, the impact on overall survival (OS) is still unknown. Aims: The aim of this study is to analyze the impact of preoperative chemotherapy on the outcome for up-front resectable borderline CLMs (BLR-CLM). Methods: A retrospective review was performed of 169 patients who underwent liver resection of BLR-CLM among 510 patients underwent liver resection for CLM between 2005 and 2013. BLR-CRLM was defined as CRLM of four or more nodules or 5cm or larger nodule. Time to surgical failure (TSF) was defined as the time until unresectable relapse or death. OS, recurrence free survival (RFS) and TSF were compared between BLR-CLM treated with neoadjuvant chemotherapy (NAC) and up-front surgery (US). Results: After median follow-up period of 38 months, 5-year survival rate after liver resection of resectable cases (n = 263), BLR-CLM (n = 169), and initially unresectable CLM (n = 78) are 67.7%, 47.5% and 32.6%, respectively. For patients with BLR-CLM, 22 patients with early recurrence during or early after postoperative chemotherapy for the primary were excluded. In the remaining 147 patients, 75 patients were treated with NAC and 72 with US. Cumulative 5-year overall survival rates, progression free survival rates, and time-to surgical failure in NAC and US group are as follows: OS (60.1% vs 47.7%, p = 0.084), PFS (23.1% vs 15.5%, p < 0.0001), TSF (38.0% vs 34.4%, p = 0.020). Conclusions: Preoperative chemotherapy for BLR-CLM could improve PFS and TSF. The impact on OS was still marginal. Prospective controlled study will be necessary.

Introduction: Radical liver resection is the only method for the treatment of patients with colorectal liver metastases (CLM); however, only 20–30% of patients with CLMs can be radically treated. Radiofrequency ablation (RFA) is one of the possible methods of palliative treatment in such patients. Methods: RFA was performed in 381 patients with CLMs between 01 Jan 2001 and 31 Dec 2018. The mean age of the patients was 65.2±8.7 years. The male to female ratio was 2:1. Open laparotomy was done in 238 (62.5%) patients and the CT-navigated transcutaneous approach was used in 143 (37.5%) patients. CLMs <5 cm (usually <3 cm) in diameter were the indication for RFA. We used RFA as the only method in 334 (87.6%) patients; RFA in combination with resection was used in 36 (9.4%), and with multi-stage resection in 11 (3%) patients. We performed RFA in a solitary CLM in 170 (44.6%) patients, and in 2−5 CLMs in 211 (55.6%) patients. We performed computed tomography in each patient 48 hours after procedure. Results: The 30-day postoperative mortality was zero. Complications were present in 4.8% of transcutaneous and in 14.2% of open procedures, respectively, in the 30-day postoperative period. One-, 3-, 5- and 10-year overall survival rates were 94.8, 66.8, 43.9 and 16.6%, respectively, in patients undergoing RFA, and 90.6, 69.1, 52.8 and 39.2%, respectively, in patients with liver resections. Disease free survival was 63.2, 30.1, 18.4 and 13.1%, respectively, in the same patients after RFA, and 71.1, 33.3, 22.8 and 15.5%, respectively, after liver resections. Conclusion: RFA is a palliative thermal ablation method, which is one of therapeutic options in patients with radically non-resectable CLMs. RFA is useful especially in a non-resectable, or resectable (but for the price of large liver resection) solitary CLM <3 cm in diameter and in CLM relapses. RFA is also part of multi-stage liver procedures.
