Improved survival is associated with an increased number of lymph nodes (LNs) examined. The aim of this study was to assess whether the examination of >or=12 LNs is associated with more accurate colon cancer staging. ⋯ Our study demonstrates that the proportion of LN-positive colon cancer is far higher when >or=12 LNs are examined. Examination of >or=12 LNs may improve staging accuracy and outcome with optimal use of systemic chemotherapy.

Despite increasing evidence on the success of laparoscopic resection in colorectal diseases, clinicians remain skeptical about the application of laparoscopic resection in rectal cancer, although it may benefit patients by resulting in early return of bowel function, reduced postoperative pain, and shorter hospital stay. Rectal cancer surgery has been regarded as a technically demanding procedure. Deviation from the oncologic principle of mesrectal dissection will lead to a higher local recurrence rate. ⋯ In recent years, there has been increasing number of reports on laparoscopic resection of rectal cancers. Apart from the issues on postoperative outcomes and long-term results, laparoscopic resection has generated interest in its impact on the preservation of sexual and bladder function. We summarize the current evidence on laparoscopic resection for rectal cancer.

It remains uncertain whether routine preoperative breast magnetic resonance imaging (MRI) will lead to improved local outcomes after breast-conserving surgery (BCS) and radiation (RT) for invasive carcinoma. The purpose of this study was to determine whether MRI in the planning of the first lumpectomy reduces ipsilateral breast tumor recurrence (IBTR). ⋯ MRI evaluation of invasive carcinoma in the planning of initial lumpectomies was not associated with improved local outcomes after BCS with RT in this cohort of patients.

Surgical therapy has been proven to be the mainstay of treatment for hepatic metastases from colorectal cancer (CRM) in the appropriate patient. Previous contraindications were patients with extrahepatic disease (EHD) do not benefit from liver resection or ablation. We hypothesized that the survival of patients with EHD who receive aggressive multimodality care would be the same as those without EHD. ⋯ A thorough understanding of the biology of disease and appropriate multimodality care can lead to improved survival in patients with EHD, when compared with chemotherapy alone.

The goal of the current study is to help refine guidelines for the need for re-excision and the appropriate amount of breast tissue to re-excise in patients with early breast cancer following excisional breast biopsy when treated with breast-conserving therapy (BCT). ⋯ Evaluation of the initial excisional biopsy margin status in correlation with the invasive carcinoma-to-specimen maximum dimension ratio may be helpful for (1) identifying patients who require re-excision prior to RT and (2) predicting the quantity of additional breast tissue to excise to ensure adequate surgical margins with BCT.
