Endoscopy-assisted breast conservation surgery (E-BCS) vs conventional breast conservation surgery (C-BCS) technique for the management of early breast cancer: A systematic review and meta-analysis.

BACKGROUND: Endoscopy-assisted breast conserving surgery (E-BCS) was developed over 10 years ago as a method for breast cancer treatment with the potential advantage of less noticeable scarring. However, the evidence supporting its superiority over conventional breast conserving surgery (C-BCS) remains unclear. OBJECTIVE: This study aims to compare the outcomes of E-BCS and C-BCS for the treatment of early breast cancer. METHODS: A comprehensive search for relevant articles was performed using specific keywords in Medline, Scopus, ClinicalTrials.gov, and Cochrane Library PubMed up to October 17th, 2022. Clinical trials that compared E-BCS with C-BCS in early breast cancer patients were collected. RESULTS: Our analysis of nine studies revealed that E-BCS was associated with shorter incision length [Mean Difference (MD) -6.50 cm (95% CI -10.75, -2.26), p = 0.003, I2 = 99%] and higher cosmetic score [MD 2.69 (95% CI 1.46, 3.93), p < 0.0001, I2 = 93%] compared with C-BCS. However, E-BCS had a longer operation time [MD 35.95 min (95% CI 19.12, 52.78), p < 0.0001, I2 = 93%] and greater drainage volume [MD 62.91 mL (95% CI 2.55, 123.27), p = 0.04, I2 = 79%]. There was no significant difference in blood loss volume (p = 0.06), drainage duration (p = 0.28), postoperative complications (p = 0.69), or local recurrence (p = 0.59) between the two groups. CONCLUSION: Our study suggests that E-BCS offers a shorter incision length and better cosmetic outcome compared with C-BCS in the treatment of early breast cancer. However, E-BCS requires a longer operation time and has greater drainage volume. Further studies are needed to confirm these findings.

The role of HMGCR expression in combination therapy of simvastatin and FAC treated locally advanced breast cancer patients.

OBJECTIVE: Several studies have shown the role of statin added to the patient's chemotherapy regimen and the role of Hydroxymethylglutaryl-CoA Reductase (HMGCR) expression in predicting breast cancer patient outcomes. In our previous study, adding statins improved clinical and pathological responses in LABC patients. Furthermore, we planned to study statin's role as a combination to neoadjuvant chemotherapy (NAC) in treating locally advanced breast cancers on the basis of HMGCR expression. Moreover, we aimed to study the association between the patients' clinicopathological characteristics and HMGCR expression. METHODS: This study is a randomized, double-blinded, placebo-controlled trial in two health centers in Indonesia. Each patient enrolled with written informed consent and then randomized to receive either simvastatin 40 mg/day or a placebo, combined with the fluorouracil, adriamycin, and cyclophosphamide (FAC) NAC. RESULTS: HMGCR was associated with low staging and normal serum cholesterol in the high Ki67 level group (p = 0.042 and p = 0.021, respectively). The pre-and post-chemotherapy tumor sizes are significantly correlated in two groups (HMGCR negative expression, p = 0.000 and HMGCR moderate expression, p = 0.001) with a more considerable average decrease in tumor size compared to HMGCR strong expression group. CONCLUSION: Statin therapy might work better in HMGCR-negative or low-expression tumors, although HGMCR expression is associated with better clinical parameters in our study.

Prevalence and Determinants of COVID-19 Vaccine Acceptance in South East Asia: A Systematic Review and Meta-Analysis of 1,166,275 Respondents.

Despite its importance in guiding public health decisions, studies on COVID-19 vaccination acceptance and its determinants in South East Asia (SEA) are lacking. Therefore, this study aims to determine the prevalence of COVID-19 vaccine acceptance and the variables influencing the vaccine's acceptance. This review is registered under PROSPERO CRD42022352198. We included studies that reported vaccination acceptance from all SEA countries, utilising five academic databases (Pubmed, MEDLINE, Cochrane Library, Science Direct, and Google Scholar), three Indonesian databases (the Indonesian Scientific Journal Database, Neliti, and Indonesia One Search), two pre-print databases (MedRxiv and BioRxiv), and two Thailand databases (ThaiJo and Thai-Journal Citation Index). The analysis was conducted using STATA 17.0 with metaprop commands. The prevalence for COVID-19 vaccination acceptance in SEA was 71% (95%CI 69-74; I2 99.87%, PI: 68.6-73.5). Myanmar achieved the highest COVID-19 vaccination acceptance prevalence, with 86% (95%CI 84-89), followed by Vietnam with 82% (95% CI 79-85; I2 99.04%) and Malaysia with 78% (95%CI 72-84; I2 99.88%). None of the ten determinants studied (age, sex, education, previous COVID-19 infections, smoking and marriage status, health insurance, living together, chronic diseases, and healthcare workers) were significantly associated with acceptance. This result will be useful in guiding vaccination uptake in SEA.

Comprehensive evaluation on cancer of unknown primary site and how we managed it: A case report.

INTRODUCTION AND IMPORTANCE: Cancer of unknown primary site (CUP) is metastatic cancer without primary tumor found from comprehensive medical history, physical examination, and regular laboratory examination. Eighty percent of CUP include unfavorable groups with 3 to 6 months of median survival despite chemotherapy treatment. CASE PRESENTATION: A 52-year-old male was presented with a chief complaint of a recurrent lump in the neck and axilla. After comprehensive examinations over three years, the primary site of the metastatic tumor could not be found. Therefore, this patient was diagnosed with cancer of an unknown primary site. CLINICAL DISCUSSION: In patient with CUP, more precise therapy can only begin when the exact form of cancer is identified. However, the delay in diagnosis would worsen the patient's condition, as treatment measures cannot be implemented. CONCLUSION: Trimodal modalities including surgery, chemotherapy, and radiotherapy are suitable for CUP with squamous cell carcinoma proven in immunohistochemistry evaluation.
