Objectives: While the NCCN guidelines maintain that T4b oral cavity squamous cell carcinoma (OCSCC) should undergo either non-surgical treatments or clinical trials, promising outcomes of T4b OCSCC having surgical excision have been reported. We analyzed and compared the clinical outcomes of Taiwanese patients with pT4a and pT4b OCSCC who had undergone surgical treatment.Methods: From 2011 to 2017, a total of 4031 and 355 patients with first primary pT4a and pT4b OCSCC were identified. A propensity score (PS)-matched analysis of patients (n = 351 each) for pT4a and pT4b tumors was also performed.Results: The 5-year disease-specific and overall survival (DSS/OS) rates were more favorable in patients with pT4a than in those with pT4b OCSCC (64%/55%, p < 0.0001; 55%/43%, p < 0.0001, respectively). Compared with pT4a, those with pT4b tumors had a higher burden of the following risk factors: buccal/retromolar/hard palate subsite, male sex, depth ≥ 10 mm, and positive margins. Before PS matching, multivariable analyses revealed that pT4b tumors (versus pT4a) were an adverse prognosticator for both 5-year DSS and OS (hazard ratios: 1.32 and 1.39, respectively). However, in the PS-matched cohort, no significant differences in 5-year DSS and OS rates were observed between pT4a and pT4b OCSCC (57%/56%, p = 0.4024; 48%/44%, p = 0.1807, respectively) CONCLUSIONS: No significant outcome differences were evident between pT4b and pT4a OCSCC after PS matching. The most plausible hypothesis for the observed survival difference between T4a and T4b tumors is that it was driven by positive margins. We suggest that T4b OCSCC should undergo initial surgical excision if adequate resection is possible. [ABSTRACT FROM AUTHOR]

Abstract: Objective: To evaluate the outcome of vertebroplasty or kyphoplasty (VK), in comparison with non-VK treatment, among patients hospitalized for first-ever vertebral compression fractures (VCFs). Design: A population-based retrospective cohort study. Setting: Taiwan’ s National Health Insurance claims data. Participants: All individuals aged ≥60 years who were newly discharged after hospitalization for a primary VCF diagnosis. Intervention: Percutaneous vertebroplasty or kyphoplasty. Measurements: Study outcomes were discharge outcome (re-hospitalization within 1 week, 1 month or 6 months, categorized by diagnosis) and the prescription of anti-osteoporosis medication for secondary fracture prevention. Potential selection bias was adjusted by using propensity score matching to select one conservatively treated patient (e.g. lumbar brace, analgesics, or physical therapy) matched to one patient receiving VK. Results: The study cohort consisted of 9238 patients who had been discharged after hospitalization for a first-ever VCF between 2004 and 2007. During the index hospitalization, 1018 patients received VK, compared with 8,220 patients who did not receive VK. Patients receiving percutaneous procedure group had a consistently lower incidence of 7-day re-hospitalization for any of the three outcomes (OR = 0.48; 95% CI: 0.32–0.72). Considering the cause of re-hospitalization separately, the vertebroplasty/kyphoplasty group had a significantly lower risk of 7-day re-hospitalization for fracture-related diagnosis (OR = 0.28, 95% CI: 0.12–0.68) and musculoskeletal diagnosis (OR = 0.08, 95% CI: 0.01–0.88) as well as a significantly lower risk of 1-month re-hospitalization (OR = 0.74; 95% CI: 0.59–0.93). Conclusions: VK may protect patients with VCFs from short-term re-hospitalization and a greater need exists for anti-osteoporosis medication as secondary prevention for this at-risk patient group.

Purpose: The evidence for adjuvant therapy of oral cavity squamous cell carcinoma (OCSCC) in National Comprehensive Cancer Network (NCCN) guidelines is derived from patients with head and neck cancer. Here, we examined whether adjuvant therapy should be guided by a detailed analysis of pathologic risk factors in patients with pure OCSCC.Methods and Materials: Between 2004 and 2016, we retrospectively reviewed 1200 consecutive patients with OCSCC who underwent radical surgery and neck dissection in the Chang-Gung Memorial Hospital (CGMH). Patients were divided into 3 prognostic groups. High-risk patients were those with extranodal extension (ENE) and/or positive margins (ENE/margins+, n = 267). Intermediate-risk patients were further divided into 3 subgroups: (1) patients in whom adjuvant therapy was indicated according to the CGMH but not the NCCN guidelines (NCCN[-]/CGMH[+], n = 14); (2) patients in whom adjuvant therapy was indicated by the NCCN but not the CGMH guidelines (NCCN[+]/CGMH[-], n = 160); and (3) patients in whom adjuvant therapy was indicated according to both guidelines (NCCN[+]/CGMH[+], n = 411). Low-risk patients were those for whom adjuvant therapy was not suggested in light of either guideline (NCCN[-]/CGMH[-], n = 348).Results: According to NCCN guidelines, postoperative adjuvant therapy was indicated in 69.8% of the participants. However, only 57.7% of patients were in need of adjuvant therapy by CGMH guidelines. The following 5-year outcomes were observed in the NCCN(-)/CGMH(-), NCCN(-)/CGMH(+), NCCN(+)/CGMH(-), NCCN(+)/CGMH(+), and ENE/margins+ subgroups: locoregional control, 88%/70%/83%/79%/68%, P < .001 (NCCN[+]/CGMH[-] vs NCCN[+]/CGMH[+], P = .576); distant metastases, 2%/7%/2%/9%/36%, P < .001 (NCCN[+]/CGMH[-] vs NCCN[+]/CGMH[+], P = .003); disease-specific survival, 97%/86%/94%/84%/56%, P < .001 (NCCN[+]/CGMH[-] vs NCCN[+]/CGMH[+], P < .001); and overall survival, 92%/86%/87%/68%/42%, P < .001 (NCCN[+]/CGMH[-] vs NCCN[+]/CGMH[+], P < .001), respectively.Conclusions: Patients in the NCCN(+)/CGMH(-) subgroup, 28% (160/571[160 + 411]) of NCCN intermediate-risk patients, had more favorable 5-year disease-specific and overall survival (94% and 87%) than the NCCN(+)/CGMH(+) subgroup. The former are unlikely to derive clinical benefits from NCCN guidelines. The 70% adjuvant therapy rate required by NCCN guidelines after radical surgery might be too high, ultimately leaving room for improvement. [ABSTRACT FROM AUTHOR]

Background and Aims: The Child-Pugh (CP) score is a widely used method to assess liver function and predict postoperative outcomes in patients with hepatocellular carcinoma (HCC). Recently, the fibrosis index (FIB-4) has been demonstrated to be closely associated with liver fibrosis and cirrhosis. This study aimed to compare the capability of FIB-4 index with CP score in predicting the outcomes for HCC patients after hepatectomy.Methods: A total of 495 HCC patients who underwent hepatectomy were enrolled. The performance of the FIB-4 index in predicting postoperative liver failure (PHLF) and overall survival was compared with that of the CP score.Results: Of them, 9.3% (46/495) patients developed PHLF. The area under the receiver operating characteristic (ROC) curve of the FIB-4 index for predicting PHLF was greater than that of the CP score (0.744 versus 0.621; P = 0.044). The optimal cutoff value of the FIB-4 index for predicting PHLF was 4.16. Multivariable analyses revealed that the FIB-4 index was an independent predictor of PHLF regardless of the hepatectomy subgroups, but the CP grade was only a significant predictor of PHLF in the minor hepatectomy subgroup. The FIB-4 index (4.16) stratified patients into two distinct overall survival cohorts (P = 0.006). The FIB-4 index also classified patients with the Barcelona Clinical Liver Cancer (BCLC) stages 0 and A into two distinct overall survival cohorts (P = 0.001 and P = 0.034, respectively).Conclusion: The FIB-4 index may be a better predictor of PHLF and overall survival in HCC patients with hepatectomy than CP score.

Abstract: Background: A link between the use of alendronate and atypical diaphyseal femoral fracture has been suggested. Objective: The goal of this study was to evaluate the benefits of alendronate in preventing rehospitalization due to hip fractures and whether its use increases risk of hospitalization for atypical diaphyseal femoral fractures in Taiwan. Methods: Using Taiwan''s National Health Insurance database, we identified women with osteoporosis with a first-ever hospitalization for vertebral or hip fractures between 2001 and 2007, which consisted of all patients receiving alendronate, raloxifene, calcitonin salmon, or teriparatide after the index fracture hospitalization. Data of untreated women were obtained as the untreated cohort. Study outcomes were defined as a rehospitalization due to hip fracture or a new hospitalization for subtrochanteric or diaphyseal femoral fracture. Results: Among 11,278 women identified (mean age, 77 years), 2425 (21.5%) received alendronate, 2694 (23.9%) received other antiosteoporosis drugs, and 6159 (54.6%) were untreated. Patients in each group were comparable in fracture history and major comorbidities; untreated patients were more likely to have stroke (11.2%; P = 0.01) and those treated with alendronate were more likely to have a history of hyperlipidemia (16.2%; P = 0.03). Compared with the untreated patient cohort, our analysis suggested that patients prescribed alendronate were associated with decreased risk of rehospitalization due to hip fracture (hazard ratio = 0.67 [95% CI, 0.54–0.82]). Neither patients prescribed alendronate, nor those prescribed other antiosteoporosis drugs, differed significantly from the untreated patient cohort in terms of risk of hospitalization for atypical femoral fracture (adjusted hazard ratios = 0.77 and 0.49 [95% CI, 0.40–1.47 and 0.22–1.12], respectively). Consistent with these data, short- or long-term alendronate use was not found to be significantly associated with higher risk of atypical femoral fractures. Conclusions: This study in Taiwanese patients suggests that alendronate use was associated with a reduction in risk of rehospitalization due to hip fracture. We did not find a significant association between alendronate use and risk of hospitalization for atypical femoral fracture. [Copyright &y& Elsevier]
