Irinotecan given with 5-fluorouracil and leucovorin is currently used as first-line therapy for patients with metastatic colorectal cancer (CRC). However, the response duration is <1 year, and second-line systemic chemotherapy has limited efficacy. We analyzed the efficacy of isolated hepatic perfusion (IHP) for patients with progressive CRC liver metastases after irinotecan. ⋯ For patients with progressive CRC liver metastases after irinotecan, IHP has good efficacy in terms of response rate and duration. Continued evaluation of IHP with melphalan as second-line therapy in this clinical setting is justified.

Despite recently increasing numbers of reports on intraductal papillary mucinous tumors (IPMTs), difficulties still remain in terms of diagnosis, treatment, and prognosis. The purpose of this multicenter study was to evaluate the clinicopathologic features of IPMT in Korea and to suggest predictive criteria for malignancy in IPMT. ⋯ A significant proportion of IPMTs are malignant, although the overall prognosis of IPMT is superior to that of ordinary pancreatic cancer. Radical surgery is recommended for IPMT with the predictors of malignancy: mural nodule, tumor size (> or =30 mm), and dilated duct size (> or =12 mm).

For patients treated with initial surgery, the safety of immediate breast reconstruction after mastectomy has been demonstrated. Some concerns exist after neoadjuvant chemotherapy because this sequence is proposed for patients with large tumors and for whom adjuvant therapies are considered cornerstones of treatment. In this study, we sought to determine whether reconstruction after neoadjuvant chemotherapy and mastectomy for large operable breast cancer affects the interval between surgery and adjuvant treatment and affects survival. ⋯ Immediate breast reconstruction does not delay the starting of adjuvant therapy and has no significant effect on local relapse-free or distant disease-free survival. Additional data are needed concerning the use of flap for this indication.

A major source of morbidity after abdominoperineal resection (APR) after external beam pelvic radiation is perineal wound complications, seen in up to 66% of cases. Our purpose was to determine the effect of rectus abdominus myocutaneous (RAM) flap reconstruction on perineal wound morbidity in this population. ⋯ Perineal closure with a RAM flap significantly decreases the incidence of perineal wound complications in patients undergoing external beam pelvic radiation and APR for anorectal neoplasia. Because other complications are not increased, RAM flap closure of the perineal wound should be strongly considered in this patient population.
