Cancer Management in Saudi Arabia: Recommendations by the Saudi Oncology HeAlth Economics ExpeRt GrouP (SHARP).

Cancer is widely recognized as a major global health problem and is estimated to rank as one of the leading causes of death worldwide. Saudi Arabia has undergone remarkable socioeconomic development in the past 40 years which has contributed to the increase in cancer incidence. The high costs of new oncology medications in combination with uncertainty of long-term effectiveness and safety outcomes highlight the importance of considering value, in terms of clinical outcomes, relative to cost.

Effect of multifocality and multicentricity on outcome in early stage breast cancer: a systematic review and meta-analysis.

Women with multifocal or multicentric breast tumors (multifocality henceforth) have been reported to have greater probability of nodal metastasis and relapse and worse survival than women with unifocal tumors. However, these associations have been inconsistent and multifocality is not taken into account by staging guidelines and prognostic models. A systematic review of electronic databases identified publications exploring the association between multifocality and overall survival (OS), disease-free survival (DFS), disease-specific survival (DSS), and loco-regional relapse (LRR).

Biliary disease in pregnancy with an emphasis on the role of ERCP.

The incidence of gallstones during pregnancy is estimated to be between 3% and 12%. About one-third of pregnant patients with cholelithiasis become symptomatic and may require surgical intervention. Choledocholithiasis during pregnancy although infrequent usually requires therapeutic intervention.

Analysis of endoscopic management of occluded metal biliary stents at a single tertiary care center.

Background: A significant number of self-expandable metal stents (SEMSs) placed to palliate malignant biliary obstruction will occlude. Few data exist as to what constitutes optimal management.

Objective: Our purpose was to review the management and outcomes of patients with biliary SEMS occlusion.
