Objective: To provide survival evidence of anthracycline-free neoadjuvant chemotherapy for patients with stages Ⅱ-Ⅲ human epidermal growth factor receptor-2 (HER-2) positive and hormone receptor (HR) negative breast cancer. Methods: The prospective cohort study was conducted at the Department of Medical Oncology of Cancer Hospital, Chinese Academy of Medical Sciences. Patients with HER-2 positive and HR negative breast cancer in stages Ⅱ-Ⅲ were enrolled to receive neoadjuvant therapy (NAT) of dose-dense paclitaxel (175 mg/m(2)) plus carboplatin (AUC=4.0) biweekly for 6 cycles in combination with trastuzumab (PCbH), and matched patients who received standard adjuvant therapy of physicians' choice were recruited for survival and safety comparison. Results: From July 2013 to November 2019, 166 patients were included (neoadjuvant 51, adjuvant 115). Compared with those who received adjuvant therapy, patients receiving NAT were younger (<35 years: 19.6% vs 5.2%, P=0.014), had larger tumors (T3: 62.7% vs 7.8%, P<0.001) and more advanced diseases (stage ⅡA: 2.0% vs 41.7%, P<0.001). Patients in the neoadjuvant group all received surgery, and 96 (83.5%) in the adjuvant group received anthracycline-and-taxane-containing regimens. A total of 98 patients (49 pairs) were matched, and the covariates between the two groups were acceptably balanced. Within a median follow-up of 46.5 (range, 14-87) months, the 4-year recurrence-free survival (RFS) rate among patients who received NAT was 73.3% (95% CI: 59.0%-87.6%), versus 80.6% (95% CI: 67.9%-93.3%) among those in the adjuvant group without statistical difference (P=0.418). A similar result was observed for the 4-year overall survival (OS) [neoadjuvant versus adjuvant: 91.5% (95% CI: 81.7%-100.0%) vs 97.8% (95% CI: 93.5%-100.0%), P=0.314]. Compared with standard adjuvant therapy, PCbH was related to less neutropenia and better cardiac safety. Conclusions: These results support the consideration of anthracycline-free neoadjuvant chemotherapy combined with anti-HER-2 therapy for patients with stages Ⅱ-Ⅲ HER-2-positive and HR-negative breast cancer. Optimized regimens with both efficacy and safety are needed and to be further investigated.

Objective: To evaluate the efficacy and survival outcomes of dose-dense (biweekly) carboplatin plus paclitaxel (PC) as neoadjuvant chemotherapy (NAC) in triple-negative breast cancer (TNBC), and to explore an optimal neoadjuvant chemotherapy regimen for TNBC. Methods: Patients diagnosed as TNBC(cT1-4N0-3M0) in Cancer Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College Between January 2008 and September 2018 who received dose-dense PC and standard 3-weekly PC as NAC were 1∶1 matched using propensity score matching (PSM) to compare the efficacy, safety and survival outcomes. Results: One hundred of TNBC patients were enrolled (50 patients were divided in dose-dense group, 50 patients in standard group). The objective response rate (ORR) of dose-dense group and standard group were both 90.0% (45/50). The grade 3-4 neutropenia in dose-dense group was less than that of standard group (32.7% vs. 68.0%, P=0.001), while the rate of ALT/AST elevation in dose-dense group was higher than that of standard group (57.1% vs. 32.0%, P=0.012). The pathological complete response (pCR) rates were 34.0% (17/50) in dose-dense group and 38.0% (19/50) in standard group, without statistically significance (P=0.677). The median follow-up time was 55 months (3-150 months). The 5-year recurrence-free survival (RFS) in dose-dense group and standard group were 83.5% and 75.2%, respectively the 5-year overall survival (OS) in dose-dense and standard group were 87.9% and 84.5% the difference were not statistically significant (P=0.322 and 0.647, respectively). Patients with residual disease (tumor size≥1 cm or lymph node positive) had poor prognosis, the 5-year RFS and OS were 59.3% and 68.5%, respectively. Conclusions: Dose-dense PC has similar efficacy with standard 3-weekly PC and has a good safety profile. Since dose-dense regimen can shorten the duration of therapy, it can be an alternative in TNBC.

OBJECTIVE: To observe the early efficacy and toxicity of docetaxel combined with carboplatin in patients with metastatic castration-resistant prostate cancer (mCRPC). METHODS: From May 2017 to July 2019, fifteen patients with mCRPC treated in Peking University First Hospital were collected. The median age was 70 years (43-77 years), and the pathological types were all adenocarcinoma, which was confirmed as distant metastasis by imaging examination. They were given the chemotherapy of docetaxel combined with carboplatin. The specific method was as follows: each cycle was 28 days. Androgen deprivation therapy was administered routinely throughout the treatment period. Blood routine, liver and kidney function, blood clotting function and prostate-specific antigen (PSA) tests were performed before each cycle. Docetaxel was administered intravenously on the first day of each cycle at a dose of 75 mg/m², and carboplatin was administered intravenously on the second day at the dose calculated by Calvert formula. The main outcome measures including PSA decline range, pain remission rate and occurrence of adverse reactions were observed and analyzed. RESULTS: Among the 15 patients, 12 had completed at least 4 cycles of chemotherapy and had short-term efficacy evaluation. PSA decline range > 50% was observed in 8 patients (66.7%). Among the 9 patients with bone pain, remarkable pain relief was observed in 4 patients (44.4%). Among the 4 patients with measurable metastatic lesions, 2 achieved partial response, 1 was evaluated as stable disease, and 1 was evaluated as progressive disease. The main adverse reactions of chemotherapy included bone marrow suppression, gastrointestinal reactions, fatigue and neurological disorders, and most of them were within the tolerable range. CONCLUSION This report is a case series study of docetaxel combined with carboplatin in the treatment of mCRPC reported in China and the conclusions are representative. The chemotherapy of docetaxel combined with carboplatin has positive short-term efficacy and high safety in patients with mCRPC, which is worthy of further promotion and exploration in clinical practice.

OBJECTIVE: To compare the efficacy and toxicity of dose-dense weekly paclitaxel and 3-weekly carboplatin (ddPC) as neoadjuvant chemotherapy (NAC) with the standard 3-weekly regimen.METHODS: A retrospective study of patients diagnosed with stage IIIc and IV ovarian cancer who received at least one cycle of NAC followed by interval debulking surgery between August 2015 and January 2018 was conducted. Patient characteristics, clinical and pathological response to NAC, surgical and survival outcome, and adverse event were compared.RESULTS: A total of 23 patients in the ddPC group and 50 patients in the standard group received a median of 3 cycles of NAC. Rate of grade ≥3 neutropenia was significantly higher in the ddPC group than the standard (82.6% vs. 22.0%, p<0.001). Patients in the ddPC group underwent dose-reduction more frequently (34.8% vs. 4.00%, p=0.001). Normalization of cancer antigen-125 post-NAC occurred more frequently in the ddPC group (73.9% vs. 46.0%, p=0.030). No residual disease rate (43.5% vs. 60.0%, p=0.188) and chemotherapy response score of 3 (34.8% vs. 26.0%, p=0.441) were not statistically different between two groups. There was no statistical difference in progression free survival (PFS) at 2 years (36.3% vs. 28.4%, p=0.454). Cox proportional hazard model showed that ddPC was not a significant determinant of PFS (p=0.816).CONCLUSION: There was no difference between both regimens in terms of NAC response and survival outcomes. However, ddPC group showed higher hematologic toxicity requiring dose reduction.

OBJECTIVE: To evaluate the effectiveness and safety of the combination of pegylated liposomal doxorubicin with carboplatin (CD) compared with those of carboplatin and paclitaxel (CP) for platinum-sensitive recurrent ovarian, fallopian, or primary peritoneal cancer in a real-world setting in Korea.METHODS: We enrolled relevant patients from 9 institutions. All patients received CD or CP as the second- or third-line chemotherapy in routine clinical practice during 2013–2018. The primary endpoints were progression-free survival (PFS) and toxicity. The secondary endpoint included the objective response rate (ORR).RESULTS: Overall, 432 patients (224 and 208 in the CD and CP groups, respectively) were included. With a median follow-up of 18.9 months, the median PFS was not different between the groups (12.7 vs. 13.6 months; hazard ratio, 1.161; 95% confidence interval, 0.923–1.460; p=0.202). The ORR was 74.6% and 80.1% in the CD and CP group, respectively (p=0.556). Age and surgery at relapse were independent prognostic factors. More patients in the CD group significantly experienced a grade 3 to 4 hematologic toxicity and hand-foot syndrome (13.8% vs. 6.3%), whereas grade 2 or more alopecia (6.2% vs. 36.1%), peripheral neuropathy (4.4% vs. 11.4%), and allergic/hypersensitivity reaction (0.4% vs. 8.5%) developed more often in the CP group.CONCLUSIONS: The safety and effectiveness of chemotherapy with CD in a real-world setting were consistent with the results from a randomized controlled study. The different toxicity profiles between the 2 chemotherapy (CD and CP) regimens should be considered in the clinical practice.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03562533

carboplatin area under the curve 4 and pegylated liposomal doxorubicin [PLD] 30 mg/m2, n=24) for 6 cycles or arm B (observation, n=21). The primary end-point was PFS. A post hoc translational study was conducted to deep sequence BRCA/homologous recombination deficiency (HRD) genes, because BRCA/HRD mutations (BRCA/HRDm) are known to be associated with better prognosis.RESULTS: Enrollment was slow, accrual was closed when 7+ years had passed. With a median follow-up of 88.9 months, the median PFS was significantly better in arm A (55.5 months) than arm B (9.2 months) (hazard ratio [HR]=0.40; 95% confidence interval [CI]=0.19–0.87; p=0.020), yet the median overall survival was not significantly different in arm A (not reached) than arm B (95.1 months) (p=0.148). Overall grade 3/4 adverse events were more frequent in arm A than arm B (60.9% vs 0.0%) (p<0.001). Quality of life was generally not significantly different. Distribution of BRCA1/2m or BRCA/HRDm was not significantly biased between the two arms. Wild-type BRCA/non-HRD subgroup seemed to fare better with maintenance therapy (HR=0.35; 95% CI=0.11–1.18; p=0.091).CONCLUSIONS: Despite limitations in small sample size, it suggests that maintenance carboplatin-PLD chemotherapy could improve PFS in advanced ovarian cancer.]]>

OBJECTIVE: To investigate the effect of bevacizumab in the treatment of children with optic pathway glioma (OPG). METHODS: A retrospective analysis was performed for the clinical data of 30 children with OPG who underwent chemotherapy. According to whether bevacizumab was used, they were divided into conventional chemotherapy (carboplatin, vincristine and etoposide) group with 12 children and combined chemotherapy (bevacizumab, carboplatin, vincristine and etoposide) group with 18 children. The children were followed up to 6 months after chemotherapy, and the two groups were compared in terms of visual acuity and tumor size before and after chemotherapy and adverse reactions during chemotherapy. RESULTS: The combined chemotherapy group had a significantly higher proportion of children achieving tumor regression than the conventional chemotherapy group (P<0.05), while there were no significant differences between the two groups in the proportion of children with improved visual acuity or adverse reactions (P>0.05). No chemotherapy-related death was observed in either group. CONCLUSIONS Bevacizumab combined with conventional chemotherapy can effectively reduce tumor size. Compared with conventional chemotherapy, such combination does not increase adverse reactions and can thus become a new direction for the treatment of OPG in children.

The long-term survival of heavily pretreated patients with primary peritoneal cancer (PPC) is uncommon. Here, we report on a patient with PPC refractory to multiple lines of intravenous chemotherapy, namely, a combined regimen of paclitaxel and carboplatin, and single regimens of topotecan, docetaxel, cisplatin, and gemcitabine. However, after intraperitoneal (IP) chemotherapy with paclitaxel-cisplatin, the patient's condition improved, and she has been progression-free for more than 4 years. Interestingly, before the IP chemotherapy, the recurrences were limited to the peritoneal cavity. These results suggest that IP recurrence might be a predictor of a good response to IP chemotherapy.

PURPOSE: Recurrence and chemoresistance (CR) are the leading causes of death in patients with high-grade serous carcinoma (HGSC) of the ovary. The aim of this study was to identify genetic changes associated with CR mechanisms using a patient-derived xenograft (PDX) mouse model and genetic sequencing. MATERIALS AND METHODS: To generate a CR HGSC PDX tumor, mice bearing subcutaneously implanted HGSC PDX tumors were treated with paclitaxel and carboplatin. We compared gene expression and mutations between chemosensitive (CS) and CR PDX tumors with whole exome and RNA sequencing and selected candidate genes. Correlations between candidate gene expression and clinicopathological variables were explored using the Cancer Genome Atlas (TCGA) database and the Human Protein Atlas (THPA). RESULTS: Three CR and four CS HGSC PDX tumor models were successfully established. RNA sequencing analysis of the PDX tumors revealed that 146 genes were significantly up-regulated and 54 genes down-regulated in the CR group compared with the CS group. Whole exome sequencing analysis showed 39 mutation sites were identified which only occurred in CR group. Differential expression of SAP25,HLA-DPA1, AKT3, and PIK3R5 genes and mutation of TMEM205 and POLR2A may have important functions in the progression of ovarian cancer chemoresistance. According to TCGA data analysis, patients with high HLA-DPA1 expression were more resistant to initial chemotherapy (p=0.030; odds ratio, 1.845). CONCLUSION: We successfully established CR ovarian cancer PDX mouse models. PDX-based genetic profiling study could be used to select some candidate genes that could be targeted to overcome chemoresistance of ovarian cancer.
