Background: Various approaches for endoscopic thyroidectomy have been developed recently that improve the cosmetic outcome, and some are even scar free. In this study, we compared the safety and surgical outcomes of transoral endoscopic thyroidectomy vestibular approach (TOETVA) and unilateral axillobreast approach (UABA) thyroid surgery performed by a single surgeon. Materials and Methods: We conducted a prospective cohort study among 101 patients undergoing endoscopic thyroidectomy from 2018 to 2019 in our institution. The factors analyzed included patients' clinical characteristics, types and time of operation, blood loss, hospital stay, postoperative complications, and cosmetic satisfaction. Results: Among 101 patients, 51 underwent TOETVA and 50 had UABA surgery. UABA has shorter operative time for lobectomy (91.7 ± 16.5 minutes versus 50.4 ± 6.8 minutes, P < .001), whereas TOETVA is associated with less postoperative pain (visual analogue scale score day 1 of 4.6 ± 1.0 versus 5.8 ± 1.0, P < .001). There were no significant differences between TOETVA and UABA groups regarding rates of transient recurrent laryngeal nerve injury (9.8% versus 2.0%, P = .205) and hypothyroidism (11.5% versus 2.0%, P = .112), in which all patients fully recovered 6 months after surgery and most of them were satisfied with the cosmetic result. Conclusions: Both TOETVA and UABA have been shown to be effective and safe surgical options for endoscopic thyroid surgery, as well as gave excellent cosmetic result. Each approach has its own advantages and disadvantages, and choice of technique should be tailored for each individual, and patient preference should be integrated in the treatment plan.

Community acquired bloodstream infection (CABSI) in low- and middle income countries is associated with a high mortality. This study describes the clinical manifestations, laboratory findings and correlation of SOFA and qSOFA with mortality in patients with CABSI in northern Vietnam. This was a retrospective study of 393 patients with at least one positive blood culture with not more than one bacterium taken within 48 h of hospitalisation. Clinical characteristic and laboratory results from the first 24 h in hospital were collected. SOFA and qSOFA scores were calculated and their validity in this setting was evaluated. Among 393 patients with bacterial CABSI, approximately 80% (307/393) of patients had dysfunction of one or more organ on admission to the study hospital with the most common being that of coagulation (57.1% or 226/393). SOFA performed well in prediction of mortality in those patients initially admitted to the critical care unit (AUC 0.858, 95%CI 0.793–0.922) but poor in those admitted to medical wards (AUC 0.667, 95%CI 0.577–0.758). In contrast qSOFA had poor predictive validity in both settings (AUC 0.692, 95%CI 0.605–0.780 and AUC 0.527, 95%CI 0.424–0.630, respectively). The overall case fatality rate was 28%. HIV infection (HR = 3.145, p = 0.001), neutropenia (HR = 2.442, p = 0.002), SOFA score 1-point increment (HR = 1.19, p < 0.001) and infection with Enterobacteriaceae (HR = 1.722, p = 0.037) were independent risk factors for in-hospital mortality. Organ dysfunction was common among Vietnamese patients with CABSI and associated with high case fatality. SOFA and qSOFA both need to be further validated in this setting.

Epidemiological characteristics of hepatocellular carcinoma (HCC) in Southern Vietnam has been well reported as in Globocan 2018 while data from the North has still not been fully presented. Therefore, we conducted this retrospective descriptive study on 198 advanced HCC patients treated at 3 major hospitals in Northern Vietnam to describe demographic features, HCC risk factors, and correlation among them in patients with advanced HCC. This information will lead to prevention efforts and provide information for allocating funds for treatment. The median age at diagnosis was 57 years (range: 19-86) and the male/female ratio was 8.9/1. The proportions of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection were 81.3% and 5.6%, respectively. Hepatitis C virus infection rate was significantly higher in patients <50 years old (12.5% vs 3.3%, P = .016). There was no significant difference in age or viral hepatitis infection status by gender. Only 7.6% of patients diagnosed with advanced HCC were asymptomatic. In conclusion, with the high rate of HBV infection among patients with advanced HCC, it is necessary for increasing prevention efforts in HBV screening. Furthermore, HCV infection should be noticed in patients with advanced HCC younger than 50 years old.

Background. Obtaining tumor specimens and re-evaluating targeted markers is recommended, if possible, in breast cancer patients who relapsed after curative treatment. The biomarker status changes in rebiopsied tumors have been demonstrated to have considerable clinical implications. Objectives. To identify the changes of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) status between the primary and recurrent lesions. Materials and Methods. We conducted a study among 67 patients with recurrent breast cancer, recruited from January 2014 to September 2018 in the Vietnam National Cancer Hospital to compare ER, PR, and HER2 status between the primary and recurrent lesions. For each patient, a specimen of their primary tumor and another specimen of recurrent lesions underwent pathological assessment. Immunohistochemistry (IHC) was performed to determine ER, PR, and HER2 status in both specimens. Results. Biomarker status conversion rates (in both directions) between primary and recurrent tumors were 26.9% for ER, 38.8% for PR, and 22.4% for HER2. Overall, IHC subtypes (hormone receptor positive, HER2 amplified, and triple-negative) changed in 25 out of 67 (37.3%) cases. Conversion rates were not statistically significantly different between patients with different recurrent sites and times of recurrence. Eight out of 13 initially triple-negative patients (61.5%) had a change to positive status of either ER, PR, or HER2. Conclusion. A substantial discordance in ER, PR, and HER2 status were observed between primary breast cancer tissues and recurrent lesions. Rebiopsy could bring new therapeutic opportunities in the management of patients with recurrent breast cancer.

Background: The transoral endoscopic thyroidectomy by vestibular approach (TOETVA) has been developed for thyroid microcarcinoma (TMC) treatment worldwide, with low rate of complications and excellent oncological results. However, this approach has still not been routinely performed. Thus, in this study, we aim to demonstrate the feasibility and safety of this technique in the clinical practice. Methods: In this prospective cohort study, 29 patients diagnosed TMC and clinically node negative underwent thyroidectomy and prophylactic central lymph node dissection by TOETVA. The clinicopathologic characteristics, surgical outcomes, and cosmetic results were evaluated. Results: The mean age was 34.7 ± 8.5 years. Three patients had underlying Grave's disease. Thyroid lobectomy with isthmusectomy was performed in the majority of cases (72.4%). All patients underwent prophylactic central node dissection. The mean number of retrieved central node was 7.8 ± 3.7 (3–19). Seven patients (24.1%) had lymph node metastasis in postoperative pathology. Among them, the mean number of metastatic lymph nodes was 2.1 ± 1.7 (1–5). The mean operative time was 121.2 ± 22.6 minutes. Four patients experienced transient hoarse and 1 patient had hematoma. Visual analog scale score on first postoperative day was 2.8 ± 1.4 (0–5). Most of patients were satisfied with cosmetic outcome. Conclusions: The TOETVA is new technique for TMC in Vietnam. The initial results of oncology, postoperative complications, and cosmetic supported the application of TOETVA in TMC.
