Self-Expanding Metal Stents Improve Swallowing and Maintain Nutrition During Neoadjuvant Therapy for Esophageal Cancer.

BACKGROUND: Patients with locally advanced esophageal cancer can have significant dysphagia. Nutritional support during neoadjuvant therapy is often delivered via nasoenteric or percutaneous feeding tubes. These approaches do not allow for per-oral feeding. AIMS: Evaluate the safety and efficacy of fully covered self-expanding metal esophageal stents for nutritional support during neoadjuvant therapy. METHODS: This was a pilot, prospective study at a single tertiary center. From March 2012 to May 2013, consecutive patients with esophageal cancer eligible for neoadjuvant therapy were enrolled. Metal stents were placed prior to starting neoadjuvant therapy. Data were collected at baseline and predetermined intervals until an endpoint (surgery or disease progression). Outcomes included dysphagia grade, satisfaction of swallowing score, nutritional status (weight, serum albumin), impact on surgery, and adverse events. RESULTS: Fourteen stents were placed in 12 patients (59.1 ± 9.5 years, 11 men, 1 woman). Dysphagia grade (pre 3.4 ± 0.5 vs post 0.2 ± 0.4, p < 0.0001) and swallowing scores (20.2 ± 5.9 vs 6.3 ± 4.7, p < 0.0001) significantly improved after stent placement. Improvements were sustained throughout neoadjuvant therapy. Body weight and serum albumin levels remained stable. Adverse events included severe chest pain (2), food impaction (1), and delayed stent migration (2). Five patients underwent surgical resection. No significant chemoradiation or operative adverse events occurred due to the presence of a stent. CONCLUSIONS: During neoadjuvant therapy for esophageal cancer, self-expanding metal stents are safe and effective in relieving dysphagia and maintaining nutrition. They allow patients to eat orally, thereby improving patient satisfaction. The presence of an in situ stent did not interfere with surgery.

Durability of infliximab in Crohn's disease: a single-center experience.

BACKGROUND: Infliximab is effective maintenance for moderate to severe Crohn's disease (CD); however, problems with immunogenicity and decreased efficacy often complicate long-term use. Durability of infliximab maintenance therapy over multiple years has not been defined. METHODS: This was a retrospective, observational study of CD patients who received maintenance infliximab for ≥1 year with the intention of ongoing maintenance. Patients were categorized into those who either discontinued treatment or continued maintenance therapy. We examined the impact of demographic, clinical characteristics, and prior episodic exposure on long-term durability of infliximab therapy and also examined the reasons for discontinuation of therapy. RESULTS: A total of 153 CD patients received maintenance infliximab treatment beyond 1 year and 42 (27%) ultimately discontinued treatment. The mean duration of maintenance treatment at the time of discontinuation was 42.4 ± 19.1 months compared to a follow-up period of 49.4 ± 19.8 months in the cohort continuing therapy (P = 0.049). The main reasons for discontinuation were allergy/adverse reaction (44.2%) and decreased efficacy (38.2%). Use of concomitant immunosuppression was similar between the 2 groups (78.6% versus 83.8%, P = NS). However, the discontinued group had a higher rate of prior episodic dosing compared to CD patients who continued maintenance (28.8% versus 11.7%, P = 0.025), while there was no difference in the rate of intensified dosing (57.2% versus 50.5%, P = NS). CONCLUSIONS: One-quarter of CD patients on long-term infliximab maintenance discontinued treatment. A history of prior episodic dosing was significantly associated with infliximab discontinuation, despite concomitant immunosuppression. These data emphasize the need for optimization of infliximab for successful long-term management.
