Aflibercept in Combination With FOLFIRI as First-line Chemotherapy in Patients With Metastatic Colorectal Cancer (mCRC): A Phase II Study (FFCD 1302).

BACKGROUND: FOLFIRI (irinotecan, 5-fluorouracil, and leucovorin) + aflibercept improves median overall survival (OS) and progression-free survival (PFS) in patients with previously treated metastatic colorectal cancer (mCRC). Our aim was to investigate efficacy and tolerability of this combination in the first line. PATIENTS AND METHODS: Patients with untreated documented mCRC received aflibercept plus FOLFIRI every 14 days until progression or unacceptable toxicity in an open, phase II single-arm, multicenter trial. The primary endpoint was the 6-month PFS rate. Secondary endpoints were OS and tolerability. A 2-step Simon design was used with H0: 55% and H1= 75%. Data were analyzed in intention to treat. RESULTS: Forty-one patients were included, and 40 were analyzed (1 consent withdrawal) in 9 French centers between October 2014 and February 2017. The median age was 65 years (range, 46-81 years), 55% had ≥ 2 metastatic sites, and 50% and 15% had RAS and BRAF mutations, respectively. Twenty-two (54.5%; 95% confidence interval, 38.9%-68.5%) patients were alive and non-progressive at 6 months. FOLFIRI + aflibercept was considered ineffective, resulting in the cessation of inclusions. The median follow-up was 34 months. The overall response rate was 55%, and the disease control rate was 80%. The median duration of treatment was 5.3 months; the median PFS and OS were 8.2 and 18.6 months, respectively. Grade 3 to 4 adverse events were mainly gastrointestinal (47.5%) and vascular (32.5%). Of the patients, 87.5% had at least 1 dose modification. CONCLUSION: Although the primary objective was not met, first-line FOLFIRI + aflibercept for mCRC leads to median PFS and OS close to those reported with classical doublet and targeted agents, but with significant toxicities needing dose reduction.

Isolated Splenic Metastases of Her2+++ Gastroesophageal Junction Adenocarcinoma.

Isolated metastases from gastric adenocarcinoma to the spleen are very infrequent. Usually, there are multiple metastases from gastric cancer, and isolated splenic metastases are very rare [Lam and Tang: Arch Pathol Lab Med 2000;124:526-530] because of certain anatomical and physiological characteristics (e.g., angulation between the splenic artery and celiac trunk, paucity of afferent lymph flow toward the spleen, contractility of the spleen and major immune content). Here, we report 2 cases of isolated splenic metastases from an adenocarcinoma of the gastroesophageal junction, both with long-term survival outcome and overexpression of Her2.
