levoleucovorin and Blood-Loss--Surgical

The current study aimed at improvement of treatment effects for patients with resectable metastases of colorectal cancer in the liver with a poor prognosis. Overall 437 patients were enrolled with metastatic colorectal cancer in the liver exhibiting at least one adverse factor of long-term prognosis: multiple metastases, bilobar liver metastases, large metastases, the presence of extrahepatic metastases, etc. Combined treatment was performed for 339 (78%) patients: combined treatment with adjuvant systemic chemotherapy (163 patients), combined treatment with perioperative systemic chemotherapy (54 patients), or combined treatment of perioperative regional chemotherapy (122 patients). Surgical treatment was performed in 66 (15%) patients. The remaining group of 32 (7%) patients with resectable metastases who received only systemic chemotherapy was considered separately. All liver resections were extensive due to the widespread metastases. The complication rate stood at 56%. Mortality among operated patients was 4%. Postoperative mortality and complications as well as the intraoperative blood loss were not statistically different in two groups. Adding bevacizumab to preoperative chemotherapy did not increase blood loss. After combined treatment with adjuvant chemotherapy a 5-year survival was 26 ± 4% that significantly outperforming a 5-year survival rate after surgery (17 ± 5%), after just drug treatment a 5-year survival has not been reached, and also after combined treatment with perioperative systemic chemotherapy (13 ± 5%) and not statistically significant exceeded a 5-year survival after combined treatment with perioperative regional chemotherapy (20 ±5%). Thus our study demonstrates the benefits of combined treatment with adjuvant systemic chemotherapy for resectable metastases of colorectal cancer in the liver with a poor prognosis. For initially unresectable metastases with extrahepatic manifestations of the disease treatment should be begun with systemic chemotherapy. To liver resection in the latter cases there are resorted only after the transfer of patients in operable condition.

Peritoneal carcinomatosis (PC), which has hitherto been regarded as a lethal entity, can now be cured with surgery (treating macroscopic tumor seeding) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) (treating residual microscopic disease). The purpose of this study was to analyze the morbidity and mortality of a particular approach associating optimal (R0-R1) cytoreduction, optimal HIPEC combining oxaliplatin and irinotecan, and an optimal homogeneous intraperitoneal temperature of 43 degrees C.. A total of 106 consecutive patients were included in this prospective phase 2 study. After complete resection of the PC, HIPEC was performed by the Coliseum technique with oxaliplatin (360 mg/m2) combined with irinotecan (360 mg/m2) in 2 L/m2 of 5% dextrose, over 30 minutes at a real intraperitoneal temperature of 43 degrees C. During the hour preceding HIPEC, patients received 5-fluorouracil (400 mg/m2) and leucovorin (20 mg/m2) intravenously, resulting in tritherapy.. Postoperative mortality and morbidity rates were 4% and 66%, respectively. The most frequent complications were digestive fistula (24%), lung infection (16%), and severe hematological toxicity (11%). Statistical correlation was evidenced between morbidity and the carcinomatosis score (P = .0008), the number of resected organs (P = .0001), the duration of surgery (P = .0001), and blood loss (P = .0001).. This new approach, optimized in three respects (complete cytoreduction, combination oxaliplatin with irinotecan, and high temperature) has resulted in a relatively high but acceptable incidence of adverse events considering the expected advantage for survival.

Laparoscopic left lateral sectionectomy (LLS) has gained popularity in its use for benign and malignant tumors. This report describes the evolution of the authors' experience using laparoscopic LLS for different indications including living liver donation.. Between January 2004 and January 2009, 37 consecutive patients underwent laparoscopic LLS for benign, primary, and metastatic liver diseases, and for one case of living liver donation. Resection of malignant tumors was indicated for 19 (51%) of the 37 patients.. All but three patients (deceased due to metastatic cancer disease) are alive and well after a median follow-up period of 20 months (range, 8-46 months). Liver cell adenomas (72%) were the main indication among benign tumors, and colorectal liver metastases (84%) were the first indication of malignancy. One case of live liver donation was performed. Whereas 16 patients (43%) had undergone a previous abdominal surgery, 3 patients (8%) had LLS combined with bowel resection. The median operation time was of 195 min (range, 115-300 min), and the median blood loss was of 50 ml (range, 0-500 ml). Mild to severe steatosis was noted in 7 patients (19%) and aspecific portal inflammation in 11 patients (30%). A median free margin of 5 mm (range, 5-27 mm) was achieved for all cancer patients. The overall recurrence rate for colorectal liver metastases was of 44% (7 patients), but none recurred at the surgical margin. No conversion to laparotomy was recorded, and the overall morbidity rate was 8.1% (1 grade 1 and 2 grade 2 complications). The median hospital stay was 6 days (range, 2-10 days).. Laparoscopic LLS without portal clamping can be performed safely for cases of benign and malignant liver disease with minimal blood loss and overall morbidity, free resection margins, and a favorable outcome. As the ultimate step of the learning curve, laparoscopic LLS could be routinely proposed, potentially increasing the donor pool for living-related liver transplantation.
