Randomized Controlled Trial Comparative Study
8-year follow-up of randomized trial: cytoreduction and hyperthermic intraperitoneal chemotherapy versus systemic chemotherapy in patients with peritoneal carcinomatosis of colorectal cancer.
The treatment of peritoneal carcinomatosis is based on cytoreduction followed by hyperthermic intraperitoneal chemotherapy and combined with adjuvant chemotherapy. In 2003, a randomized trial was finished comparing systemic chemotherapy alone with cytoreduction followed by hyperthermic intraperitoneal chemotherapy and systemic chemotherapy. This trial showed a positive result favoring the studied treatment. This trial has now been updated to a minimal follow-up of 6 years to show long-term results. ⋯ With 90% of all events having taken place up to this time, this randomized trial shows that cytoreduction followed by HIPEC does significantly add survival time to patients affected by peritoneal carcinomatosis of colorectal origin. For a selected group, there is a possibility of long-term survival.

Randomized Controlled Trial Comparative Study
Laparoscopic-assisted versus open abdominoperineal resection for low rectal cancer: a prospective randomized trial.
Laparoscopic resection of colonic cancer has been shown to improve postoperative recovery without jeopardizing tumor clearance and survival, but information on low rectal cancer is scarce. The aim of this randomized trial was to compare postoperative recovery between laparoscopic-assisted versus open abdominoperineal resection (APR) in patients with low rectal cancer. Recurrence and survival data were also recorded and compared between the two groups. ⋯ Laparoscopic-assisted APR improves postoperative recovery and seemingly does not jeopardize survival when compared with open surgery for low rectal cancer. A larger sample size is needed to fully assess oncological outcomes.

Randomized Controlled Trial Comparative Study
Efficacy of iodopovidone pleurodesis and comparison of small-bore catheter versus large-bore chest tube.
To evaluate the efficacy of iodopovidone as an agent for pleurodesis in malignant pleural effusion (MPE) and to compare the efficacy of small-bore catheter (Pleuracan, Braun, Melsungen, Germany) and conventional large-bore chest tube in pleural fluid drainage and sclerotherapy. ⋯ Iodopovidone is an effective, inexpensive, safe, and easily available alternative in chemical pleurodesis in MPE. The success rates of pleurodesis were found to be similar regardless of the type of the tube inserted.

Liver surgery is the gold-standard treatment of colorectal liver metastases. Five-year survival rates may be inadequate to evaluate surgical outcomes because some patients are alive with recurrence and late recurrences are possible. The aim of this study was to analyze 10-year survival outcome in terms of late recurrence rate and prognostic factors of survival. ⋯ Liver resection for colorectal liver metastases may be curative in more than one-third of patients without negative prognostic factors. Postoperative morbidity significantly worsens long-term outcomes. The risk of recurrence after liver resection is high even after 5 years of follow-up, but re-resection can improve the outcome.

Radioguided occult lesion localization (ROLL) is a new technique to detect nonpalpable breast tumors. We report our experience using injection of a single radiotracer to localize occult lesions together with sentinel lymph node (SLN) biopsy (SNOLL). The aim of this series was to evaluate the feasibility of the technique, its efficacy, and the rate of reoperation. ⋯ This technique with a single nanocolloid tracer used both for ROLL and SLN detection is reliable for removing nonpalpable lesions. The use of this technique may have implications for further reducing reoperation rates.
