ABSTRACT

(1) Background: The prognosis of gastric cancer-associated peritoneal carcinomatosis (GCPC) is poor, with a median survival time of less than six months, and current systemic chemotherapy, including targeted therapy, is ineffective. Despite growing evidence that cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) for GCPC improves overall survival (OS), optimal patient selection remains unclear. We aimed to evaluate preoperative clinical factors and identify indicative factors for predicting postoperative OS in patients with GCPC undergoing CRS-HIPEC. (2) Methods: We retrospectively reviewed 44 consecutive patients with GCPC who underwent CRS-HIPEC between May 2015 and May 2021. Data on demographics and radiologic assessment were collected and analyzed. (3) Results: Elevated preoperative serum neutrophil-to-lymphocyte ratio > 4.4 (p = 0.003, HR = 3.70, 95% CI = 1.55-8.79) and number of computed tomography risks > 2 (p = 0.005, HR = 3.26, 95% CI = 1.33-7.98) were independently indicative of OS post-surgery. A strong correlation was observed between intraoperative peritoneal cancer index score and number of computed tomography risks (r = 0.534, p < 0.0001). Two patients after CRS-HIPEC ultimately achieved disease-free survival for more than 50 months. (4) Conclusions: Our experience optimizes GCPC patients' selection for CRS-HIPEC, may help to improve outcomes in the corresponding population, and prevent futile surgery in inappropriate patients.

ABSTRACT

BACKGROUND: Combined cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) to treat peritoneal surface malignancy (PSM) has gained a positive result compared with palliative chemotherapy alone in several cancer types. However, its postoperative care could be challenging. We aimed to develop a predicting model on early mortality. METHODS: We retrospectively reviewed 132 PSM patients who had received CRS-HIPEC. The optimal cut-off value of the neutrophil-to-lymphocyte ratio (NLR) was determined as 4.4 by using the receiver operating characteristic curve analysis with an area under the curve (AUC) of 0.75. The impact of NLR on survival was elucidated by comparing the pre-operative low (NLR≤ 4.4, n = 101) and high (NLR> 4.4, n = 31) groups using the Kaplan-Meier method. The significant variables selected in multivariate analysis on early mortality were used in prediction model development. RESULTS: Multivariate analysis showed that incomplete CRS, major postoperative complications, higher pre-operative NLR, and dynamic NLR changes were significant predictors of early mortality. Our perioperative prediction of prognosis (triple P) model contained four independent risks, and the AUC after classification was 0.860 (95% confidence interval [CI]: 0.773-0.947). External validation confirmed positive discrimination ability (AUC: 0.808, 95% CI: 0.666-0.950). CONCLUSION: In conclusion, our triple P model provides great determination in outcomes prediction and it is easily obtained, reliable, and applicable in routine practice.

ABSTRACT

BACKGROUND Duct-to-duct biliary reconstruction has been increasingly used in living-donor liver transplantation. Information regarding dual duct-to-duct biliary anastomoses is limited. We present the largest case series to date on the use of the cystic and common hepatic ducts as dual-ductal anastomosis, along with long-term follow-up results. MATERIAL AND METHODS In this study, 740 patients underwent right-lobe living-donor liver transplantation; 56 of them were documented as dual-ductal anastomoses. We analyzed recipient and donor characteristics, surgical procedures, appearance of biliary complications, corresponding interventions, and long-term biliary outcomes. RESULTS Cystic and common hepatic ducts were utilized in 56 cases of dual-ductal biliary reconstruction, which we categorized into 2 types: A (78.6%), in which the right anterior intrahepatic duct was anastomosed to the common hepatic duct and the right posterior intrahepatic duct to the cystic duct; and B (21.4%), which was the reverse of A. After a median follow-up period of 46.4 months, 23 patients (41.1%) experienced complications, including biliary leakage and biliary stricture. However, after aggressive intervention (patent biliary anastomosis in most of them), 50 of 56 patients (89.3%) had patent biliary anastomosis and restored normal liver function at the end of follow-up. A small graft (graft-to-recipient weight ratio <0.9%) was the only predictor of biliary complications after multivariate analysis. CONCLUSIONS Dual-ductal biliary reconstruction in adult right-lobe living-donor liver transplantation is challenging but feasible. Our findings support the use of the cystic duct for reconstruction in selected patients. Good long-term results can be achieved with adequate management of patients with biliary complications.

ABSTRACT

Human cytomegalovirus (CMV) infection has been reported to compromise liver transplantation (LT) outcomes. Recent studies have shown that CMV has a beneficial oncolytic ability. The aim of this study was to investigate the impact of CMV on tumor recurrence in patients with hepatocellular carcinoma (HCC) who underwent liver transplantation (LT). This retrospective study enrolled 280 HCC patients with LT at our institute between January 2005 and January 2016. Their relevant demographic characteristics, pre- and post-LT conditions, and explant histology were collected. A CMV pp65 antigenemia assay was performed weekly following LT to identify CMV infection. A total of 121 patients (43.2%) were CMV antigenemia-positive and 159 patients (56.8%) were negative. A significantly superior five-year recurrence-free survival was observed among CMV antigenemia-positive patients compared with the CMV-negative group (89.2% vs. 79.9%, p = 0.049). There was no significant difference in overall survival between the positive and negative CMV antigenemia groups (70.2% vs. 75.3%, p = 0.255). The major cause of death was HCC recurrence in CMV antigenemia-negative patients (51.3%), whereas more CMV antigenemia-positive patients died due to other bacterial or fungal infections (58.3%). In the multivariate analysis, the independent risk factors for tumor recurrence included positive CMV antigenemia (p = 0.042; odds ratio (OR) = 0.44; 95% confidence interval (CI) = 0.20-0.97), microscopic vascular invasion (p = 0.001; OR = 3.86; 95% confidence interval (CI) = 1.78-8.36), and tumor status beyond the Milan criteria (p = 0.001; OR = 3.69; 95% CI = 1.77-7.71). In conclusion, in addition to the well-known Milan criteria, human CMV is associated with a lower HCC recurrence rate after LT. However, this tumor suppressive property does not lead to prolonged overall survival, especially in severely immunocompromised patients who are vulnerable to other infections.

ABSTRACT

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is a therapeutic approach used to achieve curative treatment in intra-abdominal malignancy with peritoneal carcinomatosis (PC). However, it is a complicated procedure with high post-operative complication rates. Thus, we analyzed our preliminary data to establish whether multidisciplinary teamwork (MDT) implementation is beneficial for CRS-HIPEC outcomes. METHOD: A series of 132 consecutive patients with synchronous or recurrent PC secondary to gastrointestinal or gynecologic cancer who received CRS-HIPEC operation between May 2015 and September 2017 were included. Ninety-nine patients were categorized into the MDT group, with the 33 other patients into the non-MDT group. RESULTS: The mean PCI score was 16.3 ± 8.8. Patients in the MDT group more often presented a higher PCI score (p value = 0.038). Regarding CRS completeness (CCR 0-1), it was distributed 81.8% and 57.6% in the MDT and the non-MDT group, respectively (p value = 0.005). Although post-operative complications were common (n = 62, 47.0%), post-operative complication rates did not differ between the two groups. The cumulative OS survival rate at the first year was 75.5%. Older age (p = 0.030, HR = 4.58, 95% CI = 1.16-18.10), ECOG 2 (p = 0.030, HR = 6.41, 95% CI = 1.20-34.14), and incomplete cytoreduction (p = 0.048, HR = 2.79, 95% CI = 1.04-8.27) were independent prognostic factors for survival. CONCLUSIONS: Our experience suggests that the CRS-HIPEC performed under MDT cooperation may result in higher complete cytoreduction rates without increasing post-operative complications and hospital mortalities.

ABSTRACT

OBJECTIVE: Cytomegalovirus (CMV) infection has a significant negative impact on liver transplant (LT) recipients. We aimed to evaluate the efficacy of real-time DNA quantitative polymerase chain reaction (qPCR) in the early detection of CMV and predicting post-transplant outcomes. MATERIALS AND METHODS: This was a retrospective study that enrolled a total of 49 adult LT recipients between December 2016 and October 2019. Serial CMV qPCR were tested weekly. We used operating characteristic curve analysis to quantify qPCR replication numbers to decide the optimal threshold to predict posttransplant complications and overall survival. RESULTS: The optimal cut-off value of 180 copies/ml (=164 IU/ml) was determined. We had 40 patients in the low qPCR group (<180 copies/ml) and nine patients in the high qPCR group (≥180 copies/ml). Higher qPCR was associated with more severe CMV disease, early allograft dysfunction, major posttransplant complications, longer ICU stays, and lower 2-year overall survival (OS; all p < .05). In the univariate logistic regression model, persistent DNAemia ≥ 4 weeks after anti-CMV treatment, coexisted bacterial and/or fungal infection, and high CMV qPCR ≥ 180 copies/ml with p < .100. High CMV qPCR ≥ 180 copies/ml (p = .016; hazard ratio [HR] = 19.5; 95% confidence interval [CI] = 1.73-219.49) remained to be the only independent risk factors for major complication by the multivariate analysis. The overall 2-year OS rates were 92.5% and 66.7% in the low and the high qPCR group, respectively (p = .030). CONCLUSION: Our findings support evidence that qPCR is effective in detecting CMV infection provides an objective perspective in predicting posttransplant outcomes. High plasma CMV DNA load (defined as CMV qPCR ≥ 180 copies/ml or 164 IU/ml) not only indicates a hazard in developing major posttransplant complications but also associates with prolonged and refractory treatment courses.

ABSTRACT

Computer-assisted 3D planning has overcome the limitations of conventional 2D planning-guided orthognathic surgery (OGS), but difference for facial contour asymmetry outcome has not been verified to date. This comparative study assessed the facial contour asymmetry outcome of consecutive patients with unilateral cleft lip and palate who underwent 2D planning (n = 37)- or 3D simulation (n = 38)-guided OGS treatment for correction of maxillary hypoplasia and skeletal Class III malocclusion between 2010 and 2018. Normal age-, gender-, and ethnicity-matched individuals (n = 60) were enrolled for comparative analyses. 2D (n = 60, with 30 images for each group) and 3D (n = 43, with 18 and 25 images for 2D planning and 3D simulation groups, respectively) photogrammetric-based facial contour asymmetry-related measurements were collected from patients and normal individuals. The facial asymmetry was further verified by using subjective perception of a panel composed of 6 blinded raters. On average, the facial contour asymmetry was significantly (all p < 0.05) reduced after 3D virtual surgery planning for all tested parameters, with no significant differences between post-OGS 3D simulation-related values and normal individuals. No significant differences were observed for pre- and post-OGS values in conventional 2D planning-based treatment, with significant (all p < 0.05) differences for all normal individuals-related comparisons. This study suggests that 3D planning presents superior facial contour asymmetry outcome than 2D planning.

ABSTRACT

OBJECTIVE: Double-opposing Z-plasty (DOZ) of the Furlow method has been successfully used for the correction of marginal velopharyngeal insufficiency (VPI) by reconstructing the levator muscle and lengthening the soft palate. For a recurrent or residual marginal VPI, it was questioned whether redo DOZ could be applied to correct the problem and minimize surgical morbidity. This study reported the outcome of the redo DOZ. MATERIALS AND METHODS: The DOZ procedure was the method of choice for marginal VPI in the authors' center. To evaluate the effectiveness of the redo operation, patients with cleft palate with or without cleft lip treated from 2005 to 2014 were reviewed. Inclusion criteria were non-syndromic patients who underwent the second DOZ for the correction of marginal VPI. Clinical information, speech assessment, and nasopharyngoscopic findings were reviewed. RESULTS: The velopharyngeal function was improved from marginal to adequate in all 13 patients either subjectively or objectively. The resonance became normal in nine patients after the surgery, and the change was statistically significant. Preoperative audible nasal emission improved in four out of five patients. Complications were minor or transient including one patient with snoring. No patient complained of airway or sleep problems. CONCLUSION: Although the levator muscle sling might be disturbed by the redo DOZ procedure, the surgery was effective in correcting the residual VPI with low morbidity.
