BACKGROUND: Although the need for consolidation chemotherapy after successful induction therapy is well established in patients with acute myeloid leukemia (AML) in first complete remission (CR1), the value of consolidation chemotherapy before allogeneic hematopoietic stem cell transplantation remains controversial. METHODS: We retrospectively compared the effect of the number of pre-transplant consolidation chemotherapies on outcomes of human leukocyte antigen-matched sibling stem cell transplantation (MSDT) for patients with AML in CR1 in multicenters across China. In our study, we analyzed data of 373 AML patients in CR1 from three centers across China. RESULTS: With a median follow-up of 969 days, patients with ≥ 3 courses of consolidation chemotherapy had higher probabilities of leukemia-free survival (LFS) (85.6% vs . 67.0%, P < 0.001) and overall survival (89.2% vs . 78.5%, P  = 0.007), and better cumulative incidences of relapse (10.5% vs . 19.6%, P  = 0.020) and non-relapse mortality (4.2% vs . 14.9%, P  = 0.001) than those with ≤ 2 courses of consolidation chemotherapy. Pre-transplantation minimal residual disease-negative patients with AML in CR1 who received MSDT with ≥ 3 courses of consolidation chemotherapy had a higher probability of LFS (85.9% vs . 67.7%, P  = 0.003) and a lower cumulative incidence of relapse (9.6% vs . 23.3%, P  = 0.013) than those with ≤ 2 courses. CONCLUSION Our results indicate that patients with AML in CR1 who received MSDT might benefit from pre-transplant consolidation chemotherapy.

OBJECTIVE: To evaluate the efficacy and toxicity of paclitaxel plus carboplatin (TC)-based concurrent chemoradiotherapy (CCRT) followed by consolidation chemotherapy in the International Federation of Gynecology and Obstetrics (FIGO) stage IIIB/IVA cervical cancer patients. METHODS: We reviewed the medical records of FIGO stage IIIB/IVA cervical cancer patients (n=30) who had been intended to be treated with TC-based CCRT followed by consolidation chemotherapy (TC-CCRT-group) from April 2012–May 2016. Patients who had been treated with CCRT involving a single platinum agent (CCRT-group; n=52) or definitive radiotherapy alone (RT-group; n=74) from January 1997–September 2012 were also identified and used as historical controls. Survival was calculated using the Kaplan-Meier method and compared using the log-rank test. RESULTS: Of the 30 patients included in the TC-CCRT-group, 22 patients (73.3%) completed the planned TC-based CCRT. The most frequently observed acute grade 3/4 hematological toxicities were leukopenia and neutropenia, and diarrhea was the most common acute grade 3/4 non-hematological toxicity. After a median follow-up of 35 months, 9 patients (30.0%) had developed recurrent disease. The patients' estimated 3-year progression-free survival (PFS) and overall survival (OS) rates were 67.9% and 90.8%, respectively. In comparisons with historical control groups, the survival outcomes of TC-CCRT-group was significantly superior to CCRT-group in terms of OS (p=0.011) and significantly superior to RT-group in terms of both PFS (p=0.009) and OS (p<0.001). CONCLUSION: TC-based CCRT followed by consolidation chemotherapy is safe and effective. A randomized controlled study needs to be conducted to further evaluate the efficacy of this multimodal approach in this patient population.

OBJECTIVETo compare the efficacy and toxicity of concurrent chemoradiotherapy followed by consolidation chemotherapy (CCRT-CT) and sequential chemoradiotherapy (SCRT) in the treatment of stage III non-small cell lung cancer.

METHODSFrom February, 2007 to June, 2010, 93 patients with unresectable stage III non-small cell lung cancer were treated with SCRT or CCRT-CT. SCRT group (50 cases) received radiotherapy after 2-6 cycles of chemotherapy (median 2 cycles) followed by 0-4 cycles (median 2 cycles) of chemotherapy. CCRT-CT group (43 cases) received 2 cycles of chemotherapy every 3 weeks with concurrent radiotherapy followed by 2-4 cycles (median 2 cycles) of chemotherapy with the same drugs. The chemotherapy consisted of cisplatin plus gemcitabine, docetaxel or vinorelbine. Radiotherapy was administered using two-dimensional conformal irradiation (36-40 Gy/18-20f) followed by three-dimensional conformal boost to 56-70 Gy/28-35f (median DT64Gy) or using three-dimensional conformal irradiation 50-74 Gy/25-37f (median DT62Gy).

RESULTSThe response rates were 76.7% and 54.0% in CCRT-CT and SCRT group, respectively (P<0.05). The median progression-free time in the two groups was 16.0 and 10.0 months, with the overall survival time of 18.0 and 12.5 months, respectively. The 1-, 2- and 3-year overall survival rates were 83.7%, 48.8% and 20.9% in CCRT-CT group and 52.0%, 20.0%, and 2.0% in SCRT group, respectively (P<0.05). CCRT-CT group showed a significantly lower rate of distant metastasis than SCRT group (P<0.05), but the local recurrence rate was similar between the two groups. The main side effects included radiation pneumonitis, radiation esophagitis, nausea/vomiting and anemia/leucopenia/thrombocytopenia. CCRT-CT group had a significantly higher rate of III-IV grade nausea/vomiting and anemia/leucopenia/thrombocytopenia than SCRT group.

CONCLUSIONCompared to SCRT, CCRT-CT can improve the response rate, progression free survival and overall survival and decrease the rate of distant metastasis, but is associated with a higher toxicity.
