Comparative Study
Patients with invasive lobular breast cancer are less likely to undergo breast-conserving surgery: a population based study in the Netherlands.
The aim of this study was to compare the frequency of breast-conserving surgery (BCS) between early-stage invasive ductal (IDC) and invasive lobular breast cancer (ILC). ⋯ The incidence of BCS for patients with IDC or ILC is rising in The Netherlands. However, the increase of BCS is less explicit in patients with ILC, with a higher chance of undergoing mastectomy compared with patients with IDC.

To explore patterns of failure and postrelapse outcome of patients with retroperitoneal sarcoma primarily treated by extended resection. ⋯ When primary extended surgery limits LR, histologic subtype and grade determine the outcome. At recurrence, a second surgery is of limited benefit.

Radiation delivered as brachytherapy (BRT) via catheters placed during extremity soft tissue sarcoma (STS) resection results in acceptable local control rates; however, there are limitations in deep cavities. (125)I seeds embedded in mesh provide a flexible BRT platform that may be contoured to irregular deep cavities surfaces, but the risks and benefits are unknown. ⋯ To our knowledge, this is the first study to report safety and efficacy for permanent (125)I mesh BRT implantation after resection of deep cavity STS. Local in-field recurrence rates were relatively low in this high-risk population. However, 24 % developed complications requiring intervention. (125)I mesh BRT appears effective, but it should be used with caution.

Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is currently the only curative option for patients with peritoneal carcinomatosis of colorectal origin. Despite meticulous preoperative assessment, CRS and HIPEC appear to be impossible in a subset of patients at the time of surgery. This study investigated which clinical factors may identify these patients before surgery and reported on factors influencing survival. ⋯ CRS and HIPEC were deemed unsuitable in almost a quarter of all patients undergoing surgery. No strong clinical predictors for O&C were found, stressing the need for better preoperative imaging modalities. Survival in these patients is limited, but the majority could be treated with palliative chemotherapy resulting in survival of almost 1 year.

Robotic versus laparoscopic intersphincteric resection for low rectal cancer: comparison of the operative, oncological, and functional outcomes.
Robotic surgery was developed to overcome the limitations of laparoscopic surgery and is increasingly used to treat low rectal cancer. In this study, we compared the operative, oncological, and functional outcomes of low rectal cancer patients who underwent robotic or laparoscopic intersphincteric resection (ISR). ⋯ Robotic and laparoscopic ISR yielded similar operative, oncological, and functional outcomes in patients with low rectal cancer, despite differences in unfavorable outcome-affecting factors, including BMI, clinical N stage, cancer location, and chemoradiotherapy frequency. A randomized trial will provide more solid methodology for investigating the potential benefits of robotic ISR.
