Multicenter Study Observational Study
Factors Associated With Recurrence and Survival in Lymph Node-Negative Gastric Adenocarcinoma: A 7-Institution Study of the US Gastric Cancer Collaborative.
To determine pathologic features associated with recurrence and survival in patients with lymph node-negative gastric adenocarcinoma. ⋯ Despite absence of lymph node involvement, patients with T-stage 3 or higher have a significantly shorter time to recurrence. These patients may benefit from more aggressive adjuvant therapy and postoperative surveillance regimens.

Multicenter Study Observational Study
The Impact of Severe Anastomotic Leak on Long-term Survival and Cancer Recurrence After Surgical Resection for Esophageal Malignancy.
The aim of this study was to the determine impact of severe esophageal anastomotic leak (SEAL) upon long-term survival and locoregional cancer recurrence. ⋯ This large multicenter study provides strong evidence that SEAL adversely impacts cancer prognosis. The mechanism through which SEAL increases local recurrence is an important area for future research.

Comparative Study
Prognostic Performance of Different Lymph Node Staging Systems After Curative Intent Resection for Gastric Adenocarcinoma.
To compare the prognostic performance of American Joint Committee on Cancer/International Union Against Cancer seventh N stage relative to lymph node ratio (LNR), log odds of metastatic lymph nodes (LODDS), and N score in gastric adenocarcinoma. ⋯ When assessed as a categorical variable, LNR was the most powerful manner to stratify patients on the basis of LN status. LODDS was a better predicator of survival when LN status was modeled as a continuous variable, especially among those patients with either very low or high LNR.

Observational Study
Functional Impact of a Minor Thoracic Injury: An Investigation of Age, Delayed Hemothorax, and Rib Fracture Effects.
To investigate whether minor thoracic injuries (MTIs) relate to subsequent functional limitations. ⋯ In this prospective study of MTIs, severe to moderate disabilities were present in nearly 1 patient out of 5 at 90 days. The presence of delayed hemothorax and the number of rib fracture were associated with increased functional limitations after a MTI.

To assess the usefulness of contrast-enhanced intraoperative ultrasound (CE-IOUS) during surgery for colorectal liver metastases (CRLM) when gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (EOB-MRI) is performed as a part of preoperative imaging work-up. ⋯ CE-IOUS is useful in hepatic resection for CRLM, even if EOB-MRI and CE-CT are performed.
