Simultaneous hepatectomy and splenectomy versus hepatectomy alone for hepatocellular carcinoma complicated by hypersplenism: a meta-analysis
Bibliographic record
Abstract
BACKGROUND: This study systematically compared the efficacy and safety of simultaneous hepatectomy and splenectomy (HS) with hepatectomy (H) alone in patients with hepatocellular carcinoma (HCC) and hypersplenism. METHODS: The PubMed, Web of Science, Science Direct, EMBASE, and Cochrane Library databases were systematically searched by two independent researchers through to March 31, 2015 to identify relevant studies. All the extracted literature were managed by Bibliographic citation management software. Quality assessment of the included studies was performed using a modified Newcastle-Ottawa Scale judgment. The data were analyzed using RevMan5.2 software. RESULTS: Eight studies including a total of 761 patients with HCC and hypersplenism (360 in the HS group, 401 in the H group) were finally included in the analysis. Outcomes, including postoperative complications, perioperative mortality, operation time, 5-year survival rate, and need for blood transfusion did not differ significantly between the two groups. HS was associated with significantly more intraoperative bleeding (mean difference [MD] 57.15, 95% confidence interval [CI] 18.83-95.46, P=0.003), and CD4/CD8 ratio (MD 0.69, 95% CI 0.61-0.77, P<0.00001), CD4 subset, platelet count (MD 213.06, 95% CI 202.59-223.53, P<0.0001), white blood cell count (MD 4.85, 95% CI 4.58-5.13, P<0.0001), interferon-gamma levels (MD 18.52, 95% CI 13.93-23.11, P<0.00001), and interleukin-2 levels (MD 20.73, 95% CI 16.05-25.41, P<0.0001). In addition, lower CD8 subset (MD -7.85, 95% CI -9.07, -6.63, P<0.00001) and interleukin-10 levels (MD -18.56, 95% CI -22.61, -14.50, P<0.00001) were observed for HS. CONCLUSION: We identified that simultaneous HS do not increase postoperative complications, operation time, or perioperative mortality in patients with HCC and hypersplenism. Simultaneous splenectomy can increase postoperative white blood cell and platelet counts significantly, improve blood coagulation, reduce the incidence of postoperative bleeding, and enhance immunity. Therefore, HS is safe, effective, and feasible for patients with HCC and hypersplenism.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
