Background: No randomized studies have compared low-dose or high-dose concurrent chemoradiotherapy (CRT)., Methods: In this study, 7219 patients with stage III or IV head and neck squamous cell carcinoma (HNSCC) were enrolled and categorized into 2 groups: group 1, comprising those undergoing low-dose concurrent CRT (n = 1575), and group 2, comprising those receiving high-dose concurrent CRT (n = 5644)., Results: Cox regression analyses revealed that age ≥65 years, male, high Charlson comorbidity index (CCI) scores, radiotherapy (RT) duration ≥7.5 weeks, clinical stage IV cancer, oral cavity cancers, tobacco smoking, and total cisplatin dose ≥240 mg/m 2 were significant independent prognostic risk factors for overall survival (OS). After adjustment for confounders, the adjusted hazard ratio (aHR; 95% confidence interval [CI]) for overall mortality was 0.83 (0.78-0.89; P < .001) in patients with oral cavity HNSCC undergoing high-dose concurrent CRT and 0.82 (0.77-0.94; P < .001) in patients with nonoral cavity HNSCC receiving high-dose concurrent CRT., Conclusion: High-dose concurrent CRT can reduce the incidence of death in patients with stage III or IV HNSCC., (© 2017 Wiley Periodicals, Inc.)

Thromboembolism (TE) is a common complication in patients with multiple myeloma (MM). Immunomodulatory agents, e.g., thalidomide, have expanded the therapeutic options for treating myeloma; however, Western countries report a high incidence of thrombosis in thalidomide-treated MM patients who lack thromboprophylaxis. A Korean trial reported low TE incidence in thalidomide-treated myeloma patients (39% were given aspirin prophylactically). We aimed to elucidate the TE frequency in MM patients in Taiwan who were treated with thalidomide without TE prophylaxis. We retrospectively collected the records of MM patients who had used thalidomide from a single institute between 2004 and 2010, combined these records with two other Taiwanese studies, and compared all three with the Korean trial. In the current Taiwanese series, five of 144 patients (3.5%) developed TE as follows: three (2.1%) were venous and two (1.3%) were arterial. Only 6.1% of the patients had undergone TE prophylaxis, which is less than in the Korean trial (38.9%, p < 0.05). Of the patients in the relapsed/refractory cohort (n = 114) who were given thalidomide alone, none (0/52) developed venous TE (VTE); however, two patients (2/35, 5.7%) who were given thalidomide-dexamethasone as a salvage treatment developed VTE. In the thrombosis cohort, four patients (80%) were treated with thalidomide plus dexamethasone. In conclusion, the frequency of thalidomide-related TE in myeloma patients without effective TE prophylaxis was low in Taiwan. In relapsed/refractory myeloma patients, the VTE frequency was slightly lower compared with Western patients irrespective of treatment with thalidomide alone or combined with dexamethasone. Even in low TE incidence areas, thalidomide combined with dexamethasone was more thrombogenic compared with others.

Diabetes is a known risk factor for developing hepatocellular carcinoma (HCC). Reported rates of diabetes are higher in chronic hepatitis, cirrhosis and HCC patients. However, its effects on postoperative recurrence and survival with HCC are controversial. This study offers a retrospective analysis of the impacts of diabetes on postoperative recurrence and survival in patients with cirrhosis and HCC. A total of 389 cirrhotic patients who underwent curative resection for primary HCC at our institution between January 2000 and December 2008 were enrolled. Of them, 272 (70%) patients were classified into a non-diabetes group and 117 (30%) patients into the diabetes group. The diabetes group was divided into an oral hypoglycemic agent (OHA) control group (n = 100) and an insulin control group (n = 17). The result indicates that the diabetes group had a higher postoperative recurrence rate and poorer long-term survival rate (p = 0.001 vs. 0.01). There was no significant difference in recurrence-free survival rate between the OHA control group and the insulin control group (p = 0.17). The insulin control group had a poorer long-term surgical outcome than the OHA control group (p = 0.035). In conclusion, our results suggest that diabetes is an independent risk factor for postoperative recurrence and surgical survival of cirrhotic HCC patients. Cirrhotic HCC patients with diabetes who received hepatic resection should be closely followed-up for postoperative recurrence and long-term outcome. Moreover, an effective peri-operative sugar control planning in HCC patients with diabetes should be established.
