RESUMO

OBJECTIVE: To assess the efficacy and safety of Bufei Jiedu (BFJD) ranules as adjuvant therapy for patients with multidrug-resistant pulmonary tuberculosis (MDR-PTB). METHODS: A large-scale, multi-center, double-blinded, and randomized controlled trial was conducted in 18 sentinel hospitals in China from December 2012 to December 2016. A total of 312 MDR-PTB patients were randomly assigned to BFJD Granules or placebo groups (1:1) using a stratified randomization method, which both received the long-course chemotherapy regimen for 18 months (6 Am-Lfx-P-Z-Pto, 12 Lfx-P-Z-Pto). Meanwhile, patients in both groups also received BFJD Granules or placebo twice a day for a total of 18 months, respectively. The primary outcome was cure rate. The secondary outcomes included time to sputum-culture conversion, changes in lung cavities and quality of life (QoL) of patients. Adverse reactions were monitored during and after the trial. RESULTS: A total of 216 cases completed the trial, 111 in the BFJD Granules group and 105 in the placebo group. BFJD Granules, as an adjuvant treatment, increased the cure rate by 13.6% at the end of treatment, compared with the placebo (58.4% vs. 44.8%, P=0.02), and accelerated the median time to sputum-culture conversion (5 months vs. 11 months). The cavity closure rate of the BFJD Granules group (50.6%, 43/85) was higher than that of the placebo group (32.1%, 26/81; P=0.02) in patients who completed the treatment. At the end of the intensive treatment, according to the 36-item Short Form, the BFJD Granules significantly improved physical functioning, general health, and vitality of patients relative to the placebo group (all P<0.01). Overall, the death rates in the two groups were not significantly different; 5.1% (8/156) in the BFJD Granules group and 2.6% (4/156) in the placebo group. CONCLUSIONS: Supplementing BFJD Granules with the long-course chemotherapy regimen significantly increased the cure rate and cavity closure rates, and rapidly improved QoL of patients with MDR-PTB (Registration No. ChiCTR-TRC-12002850).

RESUMO

OBJECTIVE: To evaluate the predictive factors for efficacy and prognosis of retreatment trastuzumab in the patients with HER2 positive metastatic breast cancer (MBC) developing successive resistance to multi-line targeting therapies. METHODS: The data of 29 patients with HER2 positive MBC were collected from July 2008 to July 2010 at our department. All patients were treated with trastuzumab, lapatinib and retreated with trastuzumab sequentially. Twenty-one patients progressed during the initial trastuzumab therapy. All patients were treated with lapatinib to disease progression and retreated with trastuzumab to disease progression or death subsequently. A Log-rank test was used for univariate analysis and a Cox regression model was employed for multivariate analysis. RESULTS: The efficacy showed no significant difference between the patients with progression or those without progression during the initial trastuzumab therapy. The time-to-progression (TTP) of prior lapatinib therapy was an influencing factor of median progression-free survival (PFS) (P < 0.0001) and the duration from discontinuation of lapatinib to trastuzumab retreatment an influencing factor of median overall survival (OS) (P = 0.008) of trastuzumab retreatment in our univariate analysis. The median PFS of trastuzumab retreatment for patients with TTP of lapatinib therapy > 12 weeks (hazard ratio (HR) = 0.02, P = 0.003) or whose duration of double trastuzumab treatment ≤ 1 year (HR = 0.26, P = 0.03) was significantly prolonged in multivariate analysis. Meanwhile, the death risk of patients whose duration from discontinuation of lapatinib to trastuzumab retreatment ≤ 4 weeks decreased 89% as compared with trastuzumab retreatment (HR = 0.11, P = 0.004). CONCLUSION: TTP of prior lapatinib therapy and the duration of double trastuzumab treatment are two predictive factors of PFS of trastuzumab retreatment. And the duration from discontinuation of lapatinib to trastuzumab retreatment is an important independent prognostic factor for trastuzumab retreatment. The patients with HER2 positive MBC should be treated continually with anti-HER2 targeted therapy.

RESUMO

Breast cancer is one of the most common malignancies in women. The post-operative recurrence and metastasis are the leading causes of breast cancer-related mortality. In this study, we tried to explore the role of circulating tumor cell (CTC) detection combination PET/CT technology evaluating the prognosis and treatment response of patients with breast cancer; meanwhile, we attempted to assess the concept of "biological complete remission" (bCR) in this regard. A 56-year-old patient with breast cancer (T(2)N(1)M(1), stage IV left breast cancer, with metastasis to axillary lymph nodes and lungs) received 6 cycles of salvage treatment with albumin-bound paclitaxel plus capecitabine and trastuzumab. Then, she underwent CTC detection and PET/CT for efficacy evaluation. CTC detection combination PET/CT is useful for the evaluation of the biological efficacy of therapies for breast cancer. The bCR of the patient appeared earlier than the conventional clinical imaging complete remission and promised the histological (pathological) complete remission. The integrated application of the concepts including bCR, imageological CR, and histological CR can achieve the early and accurate assessment of biological therapeutic reponse and prognosis of breast cancer.

RESUMO

BACKGROUND: To analyze the efficacy and safety of everolimus 5 mg/day in combination with endocrine drugs in the treatment of hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer using real-world clinical data. METHODS: Clinical data of hormone receptor (HR)-positive and HER2-negative patients with advanced breast cancer treated with everolimus combined with endocrine drugs in our center between August 2012 and May 2017 were retrospectively analyzed. Curative effect and adverse reactions were evaluated. RESULTS: A total of 110 patients were enrolled in this study, and 87.3% received salvage chemotherapy. The median number of salvage treatment lines was 5 (range: 1-19). The median follow-up duration was 12 months (range: 1-56.3 months), the overall response rate (ORR) was 6.4%, the clinical benefit rate (CBR) was 31.8%, the median progression-free survival (mPFS) was 4.0 months (95% CI: 2.9-5.1 months), and the median overall survival (OS) was 17 months (95% CI: 12.1-21.9 months). The mPFS for patients who received ≤2 treatment line was 11.8 months (95% CI: 4.3-19.3 months). Univariate and multivariate analyses suggested that absence of liver metastases, secondary endocrine resistance, and number of metastasis sites <3 were the main factors influencing the benefit of everolimus combined with endocrine therapy. The most common adverse events of grade 3 were: stomatitis (5.5%), non-infectious pneumonia (1.8%), and erythra (1.8%). No grade 4 adverse reactions were observed. CONCLUSIONS: Our results showed that everolimus (5 mg/day) combined with endocrine therapy was effective and relatively safe for patients with hormone receptor-positive, HER2-negative metastatic breast cancer.

RESUMO

Prognostic factor analysis has been conducted to determine whether the parameters of clinical data and biomarkers would predict differential progression-free survival (PFS) or overall survival (OS) from lapatinib-based therapy in patients with primary or acquired resistance to trastuzumab. Treatment with lapatinib plus capecitabine for HER2-positive metastatic breast cancer (MBC) with primary or acquired resistance to trastuzumab was analyzed retrospectively. Tumor biomarkers, which came from the biopsies before the starting of lapatinib therapy, were evaluated by immunohistochemistry (IHC). Prognostic factors related to PFS or OS of the lapatinib therapy were assessed by univariate and multivariate analysis. Ki-67 index and liver metastases were the significant prognostic factors for predicting PFS of subsequent lapatinib therapy in the univariate analysis and the multivariate analysis. The risk for disease progression in patients who had a Ki-67 index<40% was 59% less than that in patients had Ki-67 ≥ 40 (HR = 0.41, 95% CI, 0.23-0.74, P = 0.003). TTP of prior trastuzumab therapy, liver metastases, and the number of metastatic sites were three independent prognostic factors of subsequent lapatinib therapy. Ki-67 index was the significant prognostic factors for predicting PFS of the subsequent second line targeted therapy in patients with trastuzumab resistance.
