Aims and MethodPharmaceutical advertising material can confuse clinical and statistical significance. We used a brief questionnaire (five questions) to evaluate psychiatrists' appreciation of this difference. This approximated to the level of critical appraisal competence of the MRCPsych part 3 examination.ResultsOf the 113 questionnaires distributed 93 were returned complete (response rate 82%). Senior trainees were significantly better than junior trainees at correctly interpreting data (mean score (maximum 5) 2.61v.2.08; P = 0.04). Consultants did less well than senior trainees, although our sample of consultant respondents was too small for significance testing.Clinical ImplicationsLearning critical appraisal for the MRCPsych examination may provide psychiatrists with valuable transferable skills and prevent gaps in our knowledge being exploited by misleading study data. Psychiatrists of all grades need to maintain their research appraisal skills and should not regard the MRCPsych examination as the end of their learning.

PurposeAlthough pegylated liposomal doxorubicin (PLD) has been approved in combination with bortezomib for relapsed/refractory multiple myeloma (MM), the antitumor efficacy and tolerability of PLD in different regimens for patients with newly diagnosed MM (NDMM) have not been fully defined.MethodsA total of 249 NDMM patients diagnosed between January 2008 and October 2019 were included in this retrospective study. Among them, 112 patients received vindesine-based chemotherapy (35 vDD and 77 vAD) and 137 received bortezomib-based chemotherapy (58 VDD and 79 VD).ResultsIn bortezomib-containing regimens, the complete response rate (48.3 vs. 30.4%, p = 0.033) and very good partial response or better rate (74.1 vs. 57.0%, p = 0.038) of VDD were significantly higher than those of VD subgroup. While no superior survival was found between VDD and VD subgroup. In vindesine-containing regimens, no statistical significance was identified between vDD and vAD in terms of response rate and survival. The occurrence rates of all cardiac AEs were similar between VDD and VD.ConclusionsThe vDD regimen was similar with vAD in the aspect of response rate, survival, and toxicity in NDMM patients. The addition of PLD to VD brought deeper response without increased toxicity, while no superior survival was found.

Purpose To determine whether the addition of intravenous (IV) vinorelbine to epirubicin increased the progression-free survival in first-line treatment of metastatic breast cancer. Patients and Methods A total of 387 patients were randomly assigned to receive IV epirubicin 90 mg/m2 on day 1 and vinorelbine 25 mg/m2 on days 1 and 8, or epirubicin 90 mg/m2 IV on day 1. Both regimens were given every 3 weeks for a maximum of 1 year but discontinued prematurely in the event of progressive disease or severe toxicity. In addition, epirubicin was discontinued at a cumulative dose of 1,000 mg/m2 (950 mg/m2 from June 1999). Prior anthracycline-based adjuvant chemotherapy and prior chemotherapy for metastatic breast cancer was not allowed. Reported results were all based on intent-to-treat analyses. Results Overall response rates to vinorelbine and epirubicin, and epirubicin alone, were 50% and 42%, respectively (P = .15). The complete response rate was significantly superior in the combination arm (17% v 10%; P = .048) as was median duration of progression-free survival (10.1 months v 8.2 months; P = .019). Median survival was similar in the two arms (19.1 months v 18.0 months; P = .50). Leukopenia related complications, stomatitis, and peripheral neuropathy were more common in the combination arm. The incidences of cardiotoxicity and constipation were similar in both arms. Conclusion Addition of vinorelbine to epirubicin conferred a significant advantage in terms of complete response rate and progression-free survival, but not in terms of survival.

Objective. Systematically evaluate the efficacy of physical ablation combined with TKI in the treatment of advanced non-small cell lung cancer (NSCLC). Methods. We performed a comprehensive search of databases including OVID, PubMed, EMBASE, the Cochrane Library, and three Chinese databases (China National Knowledge Infrastructure, Wanfang Database, and Chongqing Weipu Database). The aim was to identify randomized controlled trials (RCT) investigating physical ablation as the treatment for advanced NSCLC. We also evaluated the methodological quality of the included studies and summarized the data extracted for meta-analysis with Review Manager 5.3. Results. A total of 9 studies, including 752 patients, were evaluable. The meta-analysis results show that the complete response rate (CRR) (RR: 2.23, 95% CI: 1. 46 to 3.40, P 0.01), partial response rate (PRR) (RR: −2.25, 95% CI: 1.41 to 3.59, P 0.01), and disease control rate (DCR) (RR: −2.80, 95% CI: 1.64 to 4.80, P < 0.01) of patients with advanced NSCLC who received physical ablation combined with TKI therapy were higher than those who did not receive physical ablation therapy. The control groups from seven of the studies had a total of 606 patients with targeted therapies and chemotherapy. The complete response rate was (CRR) (RR: 2.48, 2.4895% CI: 1.55 to 2.47, P 0.01), partial response rate (PRR) (RR: −1.66, 95% CI: 1.20 to 2.31, P < 0.01), and disease control rate (DCR) (RR: −2.68, 95% CI: 1.41 to 5.06, P < 0.01) for patients with advanced NSCLC who had received physical ablation combined with targeted therapies and chemotherapy, compared to patients who had not received physical ablation therapy. This difference was statistically significant. Above all, these results showed that the clinical efficacy of physical ablation combined EGFR-TKIs therapy (regardless of whether it was combined with chemotherapy) was better than that of EGFR-TKIs therapy alone. Conclusion. Physical ablation combined with TKI treatment in patients with advanced NSCLC can improve efficacy.

Abstract   Endoscopic submucosal dissection (ESD) is the standard treatment for cT1a esophageal squamous cell carcinoma (ESCC), however its indication for the entire circumferential lesions is still controversial because of the risk of severe stricture after ESD. Therefore, several treatment options are performed based on physicians’ choice, however, each clinical course is unclear. This study aimed to clarify the long-term outcome after ESD for patients with entire circumferential cT1aN0M0 ESCC, comparing with esophagectomy or chemoradiotherapy. Methods Patients with entire circumferential cT1aN0M0 SESCC treated with ESD, chemoradiotherapy, or esophagectomy as the initial treatment between January 2010 and December 2016 in our institution were included. Patients who had a history of any malignancy at cStage II-IV within 5 years were excluded. The 5-year overall survival (OS), 5-year disease-free survival (DFS), stricture rate, refractory stricture rate (defined as requiring &gt;6 dilations), curative resection (defined as pT1a without lymphovascular invasion and negative for vertical margin in the pathological evaluation) rate of ESD, and complete response rate of chemoradiotherapy were evaluated for each treatment. Results Of the 48 eligible patients, 25/13/10 patients were performed ESD/chemoradiotherapy/esophagectomy as an initial treatment. Curative resections rate of ESD was 72%, and additional esophagectomy and chemoradiotherapy were performed in three and one patients with non-curative resection. Complete response rate of chemoradiotherapy was 100%, however, 4 patients had recurrence thereafter. No recurrences occurred after esophagectomy in all patients treated with esophagectomy. During median follow-up of 83 months, stricture and refractory stricture rate was 80/44% after ESD, 0/0% after chemoradiotherapy, and 20/10% after esophagectomy. The 5-year OS/DFS was 91/87% after ESD, 92/59% after chemoradiotherapy, and 90/90% after esophagectomy. Conclusion While some patients required additional treatments due to non-curative resection, the long-term survival after ESD for circumferential cT1aN0M0 ESCC was similar as those after chemoradiotherapy or esophagectomy. In contrast, the stricture and refractory stricture rate after ESD was higher than others. Further investigation in a large cohort is necessary to clarify the indication criteria of ESD for patients with the lesion.

One hundred sixty-five patients were randomized to receive either interferon alfa-n1 (Wellferon; Burroughs Wellcome Co, Research Triangle Park, NC) alone or with vinblastine. An initial six-cycle induction treatment consisted of interferon given at daily doses of 3, 5, 20, 20, and 20 x 10(6) U/m2 every 2 weeks. Vinblastine at a dose of 10 mg/m2 (later decreased to 5 mg/m2) was given on day 1 of alternate cycles. Toxicities were generally well tolerated. The overall response rate was 10% with no significant difference between treatment arms. Survival was also not significantly different for the arms. A small subset of patients (16) with metastases only to the lungs had a high complete response (CR) and partial response (PR) rate of 44%. Responses were durable, and overall survival of this group was much better than that of the other patients.

PURPOSE: To determine whether the source of autologous hematopoietic stem cells altered the clinical outcomes of patients undergoing high-dose chemotherapy and hematopoietic stem-cell transplantation (HSCT) for aggressive non-Hodgkin’s lymphoma (NHL). PATIENTS AND METHODS: Of 105 high-risk, persistent, or relapsed NHL patients slated for an autologous HSCT entered onto this trial, 93 eligible patients were randomized to receive cytokine-naive autologous bone marrow transplantation (ABMT) (n = 46) or mobilized peripheral-blood stem-cell transplantation (PBSCT) (n = 47). All patients received carmustine, etoposide, cytarabine, and cyclophosphamide as the conditioning regimen. PBSCT patients also received identical mobilization with granulocyte colony-stimulating factor (G-CSF) 10 μg/kg/d, and both groups received G-CSF 5 μg/kg/d after the infusion of the stem-cell product until neutrophil engraftment. RESULTS: PBSCT patients had significantly faster engraftment of all cell lineages: median time to absolute neutrophil count ≥ 500/μL, 10 days versus 13 days on the ABMT arm; median time to platelet count greater than 20,000/μL untransfused, 11 days versus 15 days on the ABMT arm; and median time to RBC transfusion independence, 8 days versus 16 days on the ABMT arm. The complete response rate was 72% for PBSCT and 54% for ABMT. The death rate before posttransplant day 100 was 2% on the ABMT arm and 6% on PBSCT arm. Event-free survival was 37% for PBSCT and 37% for ABMT. However, overall survival for PBSCT was 61% compared with 43% for ABMT. CONCLUSION: Patients with aggressive NHL receiving HSCT randomized to PBSCT demonstrated improved neutrophil engraftment and platelet and RBC transfusion independence. The complete response rate and EFS were not statistically different by randomization arm. Patients whose harvests were positive for minimal residual disease by molecular analysis had poorer EFS.
