Quality of Life Associated with Nausea and Vomiting from Anthracycline-Based Chemotherapy: A Pooled Data Analysis from Three Prospective Trials.

BACKGROUND: There is limited work on the impact of chemotherapy-induced nausea and vomiting (CINV) on quality of life (QoL) in adriamycin-cyclophosphamide (AC)-treated patients with breast cancer. The objectives of the study were the following: (a) to confirm if symptoms of CINV led to lower QoL during AC; (b) to evaluate the pattern of changes in patients' QoL during multiple cycles of AC; and (c) to assess if the QoL in an earlier cycle affected the QoL in subsequent cycles of AC. MATERIALS AND METHODS: This is a secondary pooled data analysis that included 303 Chinese patients with breast cancer who received 1,177 cycles of adjuvant AC in three prospective antiemetic studies. QoL data were based on Functional Living Index-emesis (FLIE) scored over three to four AC cycles. CINV symptoms assessed included "no significant nausea" (NSN), "significant nausea" (SN), "no vomiting" (NoV), "vomiting" (V), and complete response (CR). RESULTS: Across all AC cycles, the mean scores for the FLIE nausea domain for patients who experienced NSN versus SN were 10.92 versus 53.92, respectively (p < .0001), with lower scores indicating better QoL; the mean scores for the FLIE vomiting domain for patients who experienced NoV versus V were 1.44 versus 19.11, respectively (p < .0001), with similar results across subsequent cycles. Analysis of the effect of the QoL in cycle 1 on the QoL of subsequent cycles revealed the following: for the nausea domain, among patients who had cycle 1 FLIE scores ≥ versus < the mean, the corresponding scores in cycle 2 were 6.87 versus 36.71 (p < .0001); whereas those for cycle 3 were 7.07 versus 36.87 (p < .0001); and those for cycle 4 were 5.92 versus 21.48 (p < .0001). Similar findings were observed for the vomiting domain. Netupitant + palonosetron- or aprepitant/olanzapine-based antiemetics had significantly better QoL outcomes. CONCLUSION: CINV had a significant impact on the QoL of patients with breast cancer treated with AC over multiple cycles. IMPLICATIONS FOR PRACTICE: In this post-hoc analysis of three prospective studies on chemotherapy-induced nausea and vomiting (CINV), quality of life (QoL) using contemporary antiemetic regimens in Chinese breast cancer patients receiving doxorubicin-cyclophosphamide (AC) was evaluated. During the first and subsequent AC cycles, QoL was significantly better for patients who did not experience vomiting or significant nausea. QoL in an earlier cycle affected the QoL in subsequent AC cycles. Furthermore, recent regimens involving olanzapine/aprepitant or netupitant-palonosetron were associated with a positive impact in QoL. Antiemetic guideline-consistent practice and higher clinician awareness of the impact of CINV on QoL can further mitigate the negative effects of CINV on QoL.

Use of antiviral therapy in surveillance: impact on outcome of hepatitis B-related hepatocellular carcinoma.

BACKGROUND: Antiviral therapy for hepatitis B virus (HBV) infection is frequently prescribed for patients with chronic HBV infection during surveillance for hepatocellular carcinoma (HCC). In patients who subsequently develop HCC, the impact of antiviral therapy on the outcome of HCC remains unclear. AIMS: We aimed to study the impact of antiviral therapy on the survival of patients who developed HCC. METHODS: From two prospective surveillance cohorts, the use of antiviral therapy for patients with HCC was retrospectively reviewed. We compared the overall survival, liver function and tumour characteristics between patients with and without antiviral therapy during surveillance. Multivariate analysis was conducted to determine the independent prognostication of antiviral therapy. RESULTS: During a median follow-up of 10.1 years of 1429 patients, 148 cases of HCC were diagnosed and followed up for a median of 5.7 years. Twenty-nine patients were given antiviral therapy during surveillance and continued treatment after diagnosis of HCC. The median survival of this group of patients was better than the rest of cohorts (hazard ratio: 0.472; 95% CI: 0.25-0.89; P = 0.0191). Use of antiviral therapy remained an independent prognostic factor after adjustment for demographic factors and tumour staging on multivariate analysis. Exploratory analysis revealed that patients who commenced antiviral therapy during surveillance had lower HBV DNA, lower serum alanine transaminase, better hepatic reserves and higher rate of local treatment at diagnosis of HCC. CONCLUSION: This study provides evidence that commencement of antiviral therapy during the surveillance period is associated with improvement in overall survival in HBV-related HCC.

Prediction of outcome in cancer patients with febrile neutropenia: a prospective validation of the Multinational Association for Supportive Care in Cancer risk index in a Chinese population and comparison with the Talcott model and artificial neural network.

PURPOSE: We aimed to validate the Multinational Association for Supportive Care in Cancer (MASCC) risk index, and compare it with the Talcott model and artificial neural network (ANN) in predicting the outcome of febrile neutropenia in a Chinese population. METHODS: We prospectively enrolled adult cancer patients who developed febrile neutropenia after chemotherapy and risk classified them according to MASCC score and Talcott model. ANN models were constructed and temporally validated in prospectively collected cohorts. RESULTS: From October 2005 to February 2008, 227 consecutive patients were enrolled. Serious medical complications occurred in 22% of patients and 4% died. The positive predictive value of low risk prediction was 86% (95% CI = 81-90%) for MASCC score ≥ 21, 84% (79-89%) for Talcott model, and 85% (78-93%) for the best ANN model. The sensitivity, specificity, negative predictive value, and misclassification rate were 81%, 60%, 52%, and 24%, respectively, for MASCC score ≥ 21; and 50%, 72%, 33%, and 44%, respectively, for Talcott model; and 84%, 60%, 58%, and 22%, respectively, for ANN model. The area under the receiver-operating characteristic curve was 0.808 (95% CI = 0.717-0.899) for MASCC, 0.573 (0.455-0.691) for Talcott, and 0.737 (0.633-0.841) for ANN model. In the low risk group identified by MASCC score ≥ 21 (70% of all patients), 12.5% developed complications and 1.9% died, compared with 43.3%, and 9.0%, respectively, in the high risk group (p < 0.0001). CONCLUSIONS: The MASCC risk index is prospectively validated in a Chinese population. It demonstrates a better overall performance than the Talcott model and is equivalent to ANN model.

Dataset on chemotherapy-induced nausea and vomiting (CINV) and quality of life (QOL) during multiple chemotherapy cycles among a Chinese breast cancer patient population who were randomized to antiemetic regimens with or without olanzapine.

Chemotherapy-induced nausea and vomiting (CINV) are highly distressing symptoms for cancer patients undergoing cytotoxic chemotherapy. This dataset was obtained from a homogenous group of Chinese breast cancer patients who were uniformly planned to receive a highly emetogenic (neo)adjuvant chemotherapy regimen, consisting of doxorubicin and cyclophosphamide (commonly known as AC). Patients were being randomized to one of the two antiemetic regimens: aprepitant, ondansetron and dexamethasone with (the Olanzapine arm) or without olanzapine (the Standard arm). Patients underwent self-reported diaries and questionnaires to record their nausea and vomiting symptoms, use of rescue medication as well as their quality of life (QOL). The primary and secondary endpoints have focused on efficacy analysis during the first cycle of AC chemotherapy; the results have been reported in The Breast [1]. In this Data in Brief article, we provide outcome of the analysis of data collected during multiple cycles of chemotherapy. The data reported here include the proportion of patients with "Complete Response", "Complete Protection" and "Total Control" of emesis in the acute (0-24 h), delayed (24-120 h) and overall periods (0-120 h), as well as QOL data during all the 4 cycles of AC.

Uterine Carcinosarcoma with Alpha-Fetoprotein-Producing Hepatoid Component: A Case Report and Literature Review.

A 67-year-old woman presented with postmenopausal vaginal bleeding. Full body imaging demonstrated an intrauterine mass with deep myometrial invasion but no nodal or other metastatic disease. Uterine curettage was performed. Histologically, the tumor was an endometrioid adenocarcinoma with sarcomatous element and a hepatoid component, the latter was immunohistochemically positive for alpha-fetoprotein, HepPar-1, and arginase-1. The patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Serum alpha-fetoprotein level decreased from 31896 ug/l preoperatively to 2063 ug/l postoperatively. Eight weeks later, a rise in serum alpha-fetoprotein was detected, and a biopsy-proven vaginal recurrence was diagnosed. Palliative chemotherapy led to tumor shrinkage and a concurrent decrease in the serum alpha-fetoprotein level. A rise in serum alpha-fetoprotein, refractory to second-line chemotherapy, was accompanied by subsequent development of ureteric obstruction, ascites, and radiological evidence of peritoneal metastases. This is an unusual case of uterine carcinosarcoma with an alpha-fetoprotein-producing hepatoid adenocarcinoma component. Serum alpha-fetoprotein level corresponds to disease recurrence and progression.

Role of pharmacogenetics on adjuvant chemotherapy-induced neutropenia in Chinese breast cancer patients.

BACKGROUND: Breast cancer patients regularly undergo adjuvant chemotherapies following surgery. However, these treatments are largely associated with chemotherapeutic toxicities ranging from nausea to severe myelosuppression. In this investigation, we examined the effects of four SNPs in NR1I2, CYP3A4 and CYP3A5 genes on chemotherapy-induced severe neutropenia in 311 female Chinese breast cancer patients undergoing a standard adjuvant chemotherapy regimen. METHODS: Patients were monitored for adverse reactions throughout the treatment, then divided into "none or mild" (80 %) or "severe" (20 %) toxicity groups according to whether they suffered grade 4 neutropenia defined as having an absolute neutrophil counts (ANC) of less than 0.5 × 10(9)/L anytime during the treatment. DNA was extracted from patients' peripheral blood samples, then genotyped using allele-specific Tm-shift PCR and melting analysis. RESULTS: Logistic regression revealed that rs776746 or CYP3A5*3 strongly associated with grade 4 neutropenia (OR = 2.56, P = 0.023) after adjustment for covariates, one of which more significant factor was baseline ANC (OR = 0.68, P = 0.020). Although univariate analysis in all patients did not reveal any association at first, further analysis indicated that rs776746 is significantly associated with severe neutropenia in subgroup of breast cancer patients with normal baseline ANC (≥2.0 × 10(9)/L). These carriers of A-allele have 3.14-fold increased risk of developing severe neutropenia (P = 0.004). CONCLUSION: Our results suggested that polymorphisms in CYP3A5 might be useful pharmacogenetic markers for the prediction of severe neutropenia during chemotherapy, however, only after screening patients by their baseline ANC in the presence of gene-environmental interaction. We demonstrate an approach of pharmacogenetic analysis, in which the genetic data should be analyzed in the perspective of other clinical parameters.
