Docetaxel, Cisplatin, and 5-FU Triplet Therapy as Conversion Therapy for Locoregionally Advanced Unresectable Esophageal Squamous Cell Carcinoma.

BACKGROUND: The standard treatment for locoregionally advanced unresectable esophageal squamous cell carcinoma was radical chemoradiotherapy. However, the prognosis was modest. Emerging evidence showed the concept of induction chemotherapy with a goal of conversion surgery. METHODS: We reviewed the long-term, clinical outcomes and safety data of induction chemotherapy using docetaxel-cisplatin-5FU (DCF) and subsequent definitive treatment, either surgery or radical chemoradiotherapy (CRT), in locally advanced unresectable esophageal cancer in Queen Mary Hospital, Hong Kong. A total of 47 patients (median age 62 years, male: 41 (87.2%)) with locoregionally advanced unresectable esophageal cancer received induction DCF. The response rate was 65.9% (complete/partial response: n = 31). After induction DCF, 24 patients (41.4%) had radical surgery and 7 (14.9%) had definitive CRT. RESULTS: The median overall survival (mOS) was significantly longer in patients received subsequent surgery compared with those with definitive CRT (mOS: 40.2 vs. 9.1 months, hazard ratio 3.33, 95% confidence interval 1.22-9.07, p = 0.02) and no definitive treatment (mOS: 40.2 vs. 6.3 months, hazard ratio 8.51, 95% confidence interval 3.7-19.73, p < 0.001). Patients who received surgery, female, and those with supraclavicular lymph node involvement had a better OS. Twenty-one patients (44.7%) developed grade 3/4 adverse events during induction DCF, and two died after chemotherapy because of trachea-esophageal fistula complicated with sepsis. Eleven patients who had surgery had postoperative complications and none had postoperative mortality. CONCLUSIONS: Induction DCF and subsequent conversion surgery offered a chance of cure with long-term survival benefit and manageable toxicities in patients with locoregionally advanced unresectable esophageal cancer.

COVID-19 vaccination in patients with rheumatic diseases: Vaccination rates, patient perspectives, and side effects.

INTRODUCTION: To investigate the vaccination rate, reported side effects, and patient concerns for COVID-19 vaccination in patients with rheumatic diseases. METHODS: A multicentre cross-sectional study from rheumatology clinics in two major hospitals in Hong Kong was conducted between June 3, 2021 and October 8, 2021. Patient interviews for demographics, clinical characteristics, vaccination status, reported side effects, and factors influencing decisions about vaccination were supplemented with structured questionnaires. RESULTS: Out of 1367 patients, 413 (30.2%) had received COVID-19 vaccination. Side effects were reported in 335 (81.1%) of patients, of which the most common were injection site pain or swelling (66.3%), fatigue (57.1%), fever (19.9%), and headache (19.6%). Multivariate logistic regression models showed that males (odds ratio [OR] = 1.80; p < .001), higher education level (OR = 1.64; p < .001) and healthcare professionals (OR = 4.5; p < .001) were significantly more likely to have received the vaccine. In contrast, patients with hypertension (OR = 0.73; p = .04), systemic lupus erythematous (OR = 0.53; p < .001), stroke (OR = 0.29; p = .01), steroid therapy (OR = 0.59; p = .01), and leflunomide therapy (OR = 0.45; p = .05) were significantly less likely to be vaccinated. Younger age (age, OR = 0.96; p = .003) and messenger RNA (mRNA) vaccines (OR = 4.79; p < .001) were associated with more side effects. There was no difference in risk of side effects between specific rheumatic diseases or drug therapies. CONCLUSION: COVID-19 vaccination is associated with no increased risk of side effects in any particular disease or drug therapy, therefore vaccination should be encouraged in patients with rheumatic disease. In addition, younger age is associated minimally, while mRNA vaccine is associated with increased side effects.
