- Objective: To evaluate the oncological outcome for patients with colorectal liver metastases (CRLM) randomized to associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) or 2-stage hepatectomy (TSH). Background: TSH with portal vein occlusion is an established method for patients with CRLM and a low volume of the future liver remnant (FLR). ALPPS is a less established method. The oncological outcome of these methods has not been previously compared in a randomized controlled trial. Methods: One hundred patients with CRLM and standardized FLR (sFLR) <30% were included and randomized to resection by ALPPS or TSH, with the option of rescue ALPPS in the TSH group, if the criteria for volume increase was not met. The first radiological follow-up was performed approximately 4 weeks postoperatively and then after 4, 8, 12, 18, and 24 months. At all the follow-ups, the remaining/recurrent tumor was noted. After the first follow-up, chemotherapy was administered, if indicated. Results: The resection rate, according to the intention-to-treat principle, was 92% (44 patients) for patients randomized to ALPPS compared with 80% (39 patients) for patients randomized to TSH (P = 0.091), including rescue ALPPS. At the first postoperative follow-up, 37 patients randomized to ALPPS were assessed as tumor free in the liver, and also 28 patients randomized to TSH (P = 0.028). The estimated median survival for patients randomized to ALPPS was 46 months compared with 26 months for patients randomized to TSH (P = 0.028). Conclusions: ALPPS seems to improve survival in patients with CRLM and sFLR <30% compared with TSH.

- Objective: The aim of the study was to evaluate if associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) could increase resection rates (RRs) compared with two-stage hepatectomy (TSH) in a randomized controlled trial (RCT). Background: Radical liver metastasis resection offers the only chance of a cure for patients with metastatic colorectal cancer. Patients with colorectal liver metastasis (CRLM) and an insufficient future liver remnant (FLR) volume are traditionally treated with chemotherapy with portal vein embolization or ligation followed by hepatectomy (TSH). This treatment sometimes fails due to insufficient liver growth or tumor progression. Methods: A prospective, multicenter RCTwas conducted between June 2014 and August 2016. It included 97 patients with CRLM and a standardized FLR (sFLR) of less than 30%. Primary outcome-RRs were measured as the percentages of patients completing both stages of the treatment. Secondary outcomes were complications, radicality, and 90-day mortality measured from the final intervention. Results: Baseline characteristics, besides body mass index, did not differ between the groups. The RR was 92% [ 95% confidence interval (CI) 84%-100%] (44/48) in the ALPPS arm compared with 57% (95% CI 43%-72%) (28/49) in the TSH arm [rate ratio 8.25 (95% CI 2.6-26.6); P < 0.0001]. No differences in complications (Clavien- Dindo >= 3a) [ 43% (19/44) vs 43% (12/28)] [1.01 (95% CI 0.4-2.6); P = 0.99], 90-day mortality [8.3% (4/48) vs 6.1% (3/49)] [ 1.39 [95% CI 0.3-6.6]; P = 0.68] or R0 RRs [77% (34/44) vs 57% (16/28)] [2.55 [95% CI 0.9-7.1]; P = 0.11)] were observed. Of the patients in the TSH arm that failed to reach an sFLR of 30%, 12 were successfully treated with ALPPS. Conclusion: ALPPS is superior to TSH in terms of RR, with comparable surgical margins, complications, and short- term mortality.

- Background: Colorectal liver metastases (CRLM) not amenable for resection have grave prognosis. One limiting factor for surgery is a small future liver remnant (FLR). Early data suggests that associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) effectively increases the volume of the FLR allowing for resection in a larger fraction of patients than conventional two-stage hepatectomy (TSH) with portal vein occlusion (PVO). Oncological results of the treatment are lacking. The aim of this study was to assess the intermediate oncological outcomes after ALPPS in patients with CRLM. Material and methods: Retrospective analysis of all patients with CRLM operated with ALPPS at the participating centres between December 2012 and May 2014. Results: Twenty-three patients (16 male, 7 female), age 67 years (28-80) were operated for 6.5 (1-38) metastases of which the largest was 40 nun (14-130). Six (27.3%) patients had extra-hepatic metastases, 16 (72.7%) synchronous presentation. All patients received chemotherapy, 6 cycles (3-25) preoperatively and 16 (70%) postoperatively. Ten patients (43%) were rescue ALPPS after failed PVO. Severe complications occurred in 13.6% and one (4.5%) patient died within 90 days of surgery. After a median follow-up of 22.5 months from surgery and 33.5 months from diagnosis of liver metastases estimated 2 year overall survival was 59% (from surgery) and 73% (from diagnosis). Liver only recurrences (n = 8), were treated with reresection/ablation (n = 7) while lung recurrences were treated with chemotherapy. Conclusion: The overall survival, rate of severe complications and perioperative mortality associated with ALPPS for patients with CRLM is comparable to TSH. (C) 2016 Elsevier Ltd.

- Background: Associated liver partition and portal vein ligation in staged hepatectomy (ALPPS) is an alternative resection method to portal vein embolization (PVE) in patients with small future liver remnants (FLR) but has been associated with early tumor recurrences. Methods: Twenty-four patients with colorectal liver metastases (CRLM) patients from the randomized multicenter LIGRO trial comparing outcome of ALPPS (n = 13) vs PVE (n = 11) were included in the study. Mutational analyses of the KRAS, NRAS, BRAF, PIC3CA and TP53 genes of the metastases were performed in 21 patients and correlated to early tumor recurrence. Results: Within 12 months, 13 patients experienced recurrences (6 in TSH group and 7 in ALPPS group). Nine of 13 patients with recurrences had mutations in the TP53 gene, while 3 of 8 patients without recurrence carried the same mutation. Only sporadic cases of the other mutations studied were identified. Conclusions: ALPPS did not appear to be associated with higher rate of rapid recurrences than PVE following radical resection of colorectal liver metastases. Mutations in genes associated with negative oncologic outcome after surgical resection most likely play a role for tumor recurrences in these patients.

- Levels of HIV-1 have been reported to increase in peripheral blood after influenza vaccination of HIV+ individuals. In this study we have evaluated the dynamics of these changes. Ten HIV-1+ individuals classified in revised CDC clinical categories B and C as well as five seronegative healthy controls were vaccinated with the recommended influenza strains. HIV viral RNA and proviral DNA were sequentially quantified in serum and blood lymphocytes, respectively. Nine of the 10 HIV+ individuals had an increase in the frequency of infected CD4 cells 2 weeks after influenza vaccination. Individuals with low viral load had a rapid increase in viraemia and a small increase in frequency of infected cells in peripheral blood. In contrast, individuals with high viral load had a small drop in viraemia followed by a significant rise in the rate of infected cells. The observed changes may resemble those taking place during intercurrent infections in HIV+ individuals. The effects of the relative increases in infectious virus after the transient viraemic phase should be further investigated to evaluate potential risks of vaccination.
