ABSTRACT

BACKGROUND: Hepatectomy is currently recommended as the most reliable treatment for hepatocellular carcinoma. However, the association between the choice of treatment for recurrence and the timing of recurrence remains controversial. METHODS: Three-hundred thirty-nine patients who underwent hepatectomy were retrospectively analyzed using a propensity score matching analysis for the risk factors and outcomes for early recurrences within 6 months. The remnant liver volumes and laboratory data were measured postoperatively using multidetector computed tomography on days 7 and months 1, 2, and 5 after surgery. The Student's t test and chi-square test, the likelihood-ratio test, Fisher's exact test, Mann-Whitney U test, or Wilcoxon signed-rank test were used in the statistical analyses. RESULTS: Early recurrence developed in 41/312 patients (13.1%). Vascular invasion and non-curative resection were independent risk factors for the occurrence of early recurrence (P < 0.001 and < 0.001, respectively). Patients with early recurrence had a poorer prognosis than patients who developed later recurrences (P < 0.001). Patients who underwent surgery or other local treatments had better outcomes (P < 0.001). The changes in remnant liver volumes and laboratory data after postoperative month 2 were not significantly different between the two groups. CONCLUSION: Patients with early recurrence within 6 months had a poorer prognosis than patients who developed a later recurrence. However, patients who underwent repeat hepatectomy for recurrences had a better prognosis than did those who underwent other treatments, with good prospects for long-term survival.

ABSTRACT

INTRODUCTION: Laparoscopic liver resection (LLR) in obese patients has been reported to be particularly challenging owing to technical difficulties and various comorbidities. METHODS: The safety and efficacy outcomes in 314 patients who underwent laparoscopic or open nonanatomical liver resection for colorectal liver metastases (CRLM) were analyzed retrospectively with respect to the patients' body mass index (BMI) and visceral fat area (VFA). RESULTS: Two hundred and four patients underwent LLR, and 110 patients underwent open liver resection (OLR). The rate of conversion from LLR to OLR was 4.4%, with no significant difference between the BMI and VFA groups (P = .647 and .136, respectively). In addition, there were no significant differences in terms of operative time and estimated blood loss in LLR (P = .226 and .368; .772 and .489, respectively). The incidence of Clavien-Dindo grade IIIa or higher complications was not significantly different between the BMI and VFA groups of LLR (P = .877 and .726, respectively). In obese patients, the operative time and estimated blood loss were significantly shorter and lower, respectively, in LLR than in OLR (P = .003 and < .001; < .001 and < .001, respectively). There was a significant difference in the incidence of postoperative complications, organ/space surgical site infections, and postoperative bile leakage between the LLR and OLR groups (P = .017, < .001, and < .001, respectively). CONCLUSION: LLR for obese patients with CRLM can be performed safely using various surgical devices with no major difference in outcomes compared to those in nonobese patients. Moreover, LLR has better safety outcomes than OLR in obese patients.

ABSTRACT

A 54-year-old man with residual urine, abdominal pain, and a high fever was diagnosed with KRAS wild-type sigmoid colon cancer with urinary bladder invasion. Considering the difficulty of curative resection, we first performed an ileostomy. Remarkable tumor regression was indicated by computed tomography(CT)and colonoscopy after 3 courses of mFOLFOX6 plus panitumumab. A sigmoidectomy and partial cystectomy were performed with a curative intent. Six courses of XELOX adjuvant chemotherapy were administered, and no recurrence has been observed for 9 months. mFOLFOX6 plus panitumumab might be an effective preoperative chemotherapy for patients with locally advanced KRAS wild-type colon cancer.
