- Background: Gastroenteropancreatic neuroendocrine carcinomas (GEP-NEC) are generally characterized by synchronous metastases, high aggressiveness and a dismal prognosis. Current international guidelines do not recommend surgical treatment of liver metastases, however the existing data are scarce. The aim of this study was to evaluate the results of curatively intended resection/radiofrequency ablation (RFA) of liver metastases in patients with metastatic GEP-NEC. Methods: 32 patients with a diagnosis of high-grade gastroenteropancreatic neuroendocrine neoplasm (Ki-67 > 20%) and with intended curative resection/RFA of liver metastases, were identified among 840 patients from two Nordic GEP-NEC registries. Tumor morphology (well vs poor differentiation) was reassessed. Overall survival (OS) and progression-free survival (PFS) was assessed by Kaplan Meier analyses for the entire cohort and for subgroups. Results: Median OS after resection/RFA of liver metastases was 35.9 months (95% -CI: 20.6-51.3) with a five-year OS of 43%. The median PFS was 8.4 months (95% -CI: 3.9-13). Four patients (13%) were disease -free after 5 years. Two patients had well -differentiated morphology (NET G3) and 20 patients (63%) had Ki-67 >= 55%. A Ki-67 < 55% and receiving adjuvant chemotherapy were statistically significant factors of improved OS after liver resection/RFA. Conclusion: This study shows a long median and long term survival after liver surgery/RFA for these selected metastatic GEP-NEC patients, particularly for the group with a Ki-67 in the relatively lower G3 range. Our findings indicate a possible role for surgical treatment of liver metastases in the management of this patient population.

- Background: The aim was to evaluate activity and toxicity of hepatic arterial infusion of oxaliplatin in combination with capecitabine in patients with metastatic breast cancer with liver metastases and limited extrahepatic disease. Patients and methods: Sixteen consecutive patients received capecitabine 1300 mg/m(2) daily combined with oxaliplatin 85 mg/m2 every two weeks. Seven patients alternated between intrahepatic and systemic oxaliplatin, and in 9 oxaliplatin was primarily given intrahepatic. Five patients had liver-only metastases and 11 had additionally bone metastases. The patients had received median two previous chemotherapeutic regimens for metastatic disease. Results: The response rate was 50% and the stable disease (>= 6 months) rate 44%. Median progression free and overall survival was 7.9 and 19.2 months, respectively. The toxicity was moderate with abdominal pain, neuropathy, and hand foot syndrome as the most common adverse events. Conclusion: The combination of capecitabine and intrahepatic/systemic therapy with oxaliplatin was active in pretreated patients with liver metastasis from breast cancer. (c) 2012 Elsevier Ltd.

- As studies on gastrointestinal neuroendocrine carcinoma (WHO G3) (GI-NEC) are limited, we reviewed clinical data to identify predictive and prognostic markers for advanced GI-NEC patients. Data from advanced GI-NEC patients diagnosed 2000-2009 were retrospectively registered at 12 Nordic hospitals. The median survival was 11 months in 252 patients given palliative chemotherapy and 1 month in 53 patients receiving best supportive care (BSC) only. The response rate to first-line chemotherapy was 31% and 33% had stable disease. Ki-67 < 55% was by receiver operating characteristic analysis the best cut-off value concerning correlation to the response rate. Patients with Ki-67 < 55% had a lower response rate (15% versus 42%, P < 0.001), but better survival than patients with Ki-67 >= 55% (14 versus10 months, P < 0.001). Platinum schedule did not affect the response rate or survival. The most important negative prognostic factors for survival were poor performance status (PS), primary colorectal tumors and elevated platelets or lactate dehydrogenase (LDH) levels. Advanced GI-NEC patients should be considered for chemotherapy treatment without delay.PS, colorectal primary and elevated platelets and LDH levels were prognostic factors for survival. Patients with Ki-67 < 55% were less responsive to platinum-based chemotherapy, but had a longer survival. Our data indicate that it may not be correct to consider all GI-NEC as one single disease entity.

- Maintenance treatment (mt) with bevacizumab (bev) +/- erlotinib (erlo) has modest effect after induction chemotherapy in metastatic colorectal cancer (mCRC). We hypothesized the efficacy of erlo to be dependent on KRAS mutational status and investigated this by exploring mt strategies with bev +/- erlo and low-dose capecitabine (cap). Included patients had mCRC scheduled for first-line therapy, Eastern Cooperative Oncology Group (ECOG) 0-1 and no major comorbidities. Treatment with XELOX/FOLFOX or XELIRI/FOLFIRI + bev was given for 18 weeks. After induction, patients without progression were eligible for randomization to mt; KRAS wild-type (wt) patients were randomized to bev +/- erlo (arms wt-BE, N = 36 versus wt-B, N = 35), KRAS mutated (mut) patients were randomized to bev or metronomic cap (arms mut-B, N = 34 versus mut-C, N = 33). Primary end point was progression-free survival (PFS) rate (PFSr) at 3 months after start of mt. A pooled analysis of KRAS wt patients from the previous ACT study was performed. We included 233 patients. Median age was 64 years, 62% male, 68% ECOG 0, 52% with primary tumor in situ. A total of 138 patients started mt after randomization. PFSr was 64.7% versus 63.6% in wt-B versus wt-BE, P = 1.000; and 75% versus 66.7% in mut-B versus mut-C, P = 0.579, with no significant difference in median PFS and overall survival (OS). In the pooled cohort, median PFS was 3.7 months in wt-B (N = 64) and 5.7 months in wt-BE (N = 62) (hazard ratios 1.03, 95% confidence interval 0.70-1.50, P = 0.867). The frequency of any grade 3/4 toxicities during mt was: 28%/58%/18%/15% (wt-B/wt-BE/mut-B/mut-C). Addition of erlo to bev as mt in KRAS wt mCRC did not significantly improve PFS or OS, but it did increase toxicity. KRAS status does not seem to influence the outcome of treatment with erlotinib. Metronomic cap warrants further investigation in mt strategies, given our explorative results. NCT01229813.
