Prognostic Impact of Lymph Node Excision in T1 and T2 Gallbladder Cancer: a Population-Based and Propensity Score-Matched SEER Analysis.

Purpose: The aim of this study was to assess the effect of lymphadenectomy on survival in T1/T2 gallbladder cancer (GBC).

Methods: In this retrospective cohort study, patients undergoing surgery for T1/T2 GBC from 2004 to 2014 were identified in the Surveillance, Epidemiology, and End Results database. The effect of lymph node excision (LNE) on survival was assessed using Cox regression and propensity score methods.

Operative and medical treatment of chronic anal fissures-a review and network meta-analysis of randomized controlled trials.

Anal fissures are a common problem and have a cumulative lifetime incidence of 11%. Previous reviews on anal fissures show inconsistent results regarding post-interventional healing and incontinence rates. In this review our aim was to compare the treatments for chronic anal fissures by incorporating indirect comparisons using network meta-analysis.

Survival after Abdominoperineal and Sphincter-Preserving Resection in Nonmetastatic Rectal Cancer: A Population-Based Time-Trend and Propensity Score-Matched SEER Analysis.

Abdominoperineal resection (APR) has been associated with impaired survival in nonmetastatic rectal cancer patients. It is unclear whether this adverse outcome is due to the surgical procedure itself or is a consequence of tumor-related characteristics. Patients were identified from the Surveillance, Epidemiology, and End Results database.

Modest overall survival improvements from 1998 to 2009 in metastatic gastric cancer patients: a population-based SEER analysis.

Background: An increasing fraction of gastric cancer patients present with distant metastases at diagnosis. The objective of the present 11-year population-based trend analysis was to assess the survival rates in patients who underwent and in patients who did not undergo palliative gastrectomy.

Methods: Patients with metastatic gastric cancer were identified from the Surveillance, Epidemiology, and End Results (SEER) database between 1998 and 2009.

Anastomotic leakage after curative rectal cancer resection has no impact on long-term survival: a propensity score analysis.

Purpose: Anastomotic leakage (AL) is a severe and frequent complication of rectal cancer resection, with an incidence rate of approximately 9 %. Although the impact of AL on morbidity and short-term mortality has been established, the literature is contradictory regarding its influence on long-term, cancer-specific survival. The present investigation assessed the long-term survival of 584 patients with stage I-III rectal cancer.

Long-Term Survival is not Impaired After the Complete Resection of Neuroendocrine Tumors of the Appendix.

Background: Appendiceal neuroendocrine tumors (aNET) are a common entity in routine medical care, with a rate per appendectomy as high as 0.3-0.9 %.
