In a previous randomized, triple-masked, placebo-controlled study, the authors demonstrated that extending a single-injection paravertebral nerve block with a multiple-day perineural local anesthetic infusion improves analgesia and decreases pain-related dysfunction during the 3-day infusion but not subsequent to catheter removal within 1 month after mastectomy. This report describes a prospective follow-up study of the previously published trial to investigate the possibility that extending a single-injection paravertebral block with a multiple-day infusion may decrease persistent postsurgical pain as well as pain-induced emotional and functional dysfunction 1 year after mastectomy. ⋯ Adding a multiple-day, continuous ropivacaine infusion to a single-injection ropivacaine paravertebral nerve block may result in a lower incidence of pain as well as pain-related physical and emotional dysfunction 1 year after mastectomy.

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.

Long-term survival of patients with appendiceal or colorectal peritoneal carcinomatosis (PC) may be achieved by combining cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). Unfortunately, such favorable outcomes are realized in a minority of patients. Given the morbidity of the CRS/HIPEC and the uncertain role of postresection systemic therapy, it is important that prognostic factors in high-grade PC be clearly defined. ⋯ High-grade PC secondary to appendiceal or colorectal adenocarcinoma can be managed with CRS/HIPEC. The number of LN metastases at the time of CRS/HIPEC is the strongest predictor of progression and must be considered when determining patient eligibility for this aggressive treatment.

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.

Retrospective evaluation of local low-dose thrombolysis for treatment of venous port-catheter thrombosis. ⋯ Difficult aspiration combined with high resistance to injection fluids or suboptimal port-catheter position are strong independent predictors for port-catheter thrombosis. Local low-dose thrombolysis or repeat thrombolysis is safe and effective in the absence of large central venous thrombosis.
