MATERIALS AND METHODS: This retrospective study looked at patients who had palliative chemotherapy with either cisplatin/5FU or carboplatin/5FU for metastatic and recurrent SCCHN and NPC. It included patients who were treated at UKMMC from 1st January 2004 to 31st December 2009 with either palliative IV cispaltin 75 mg/m2 D1 only plus IV 5FU 750 mg/m2 D1-5 infusion or IV Carboplatin AUC 5 D1 only plus IV 5FU 500 mg/m2 D1-2 infusion plus IV 5FU 500 mg/m2 D1-2 bolus. The specific objectives were to determine the efficacy of palliative chemotherapy in terms of overall response rate (ORR), median progression free survival (PFS) and median overall survival (OS) and to evaluate the toxicities of both regimens.
RESULTS: A total of 41 patients were eligible for this study. There were 17 in the cisplatin/5FU arm and 24 in the carboplatin/5FU arm. The ORR was 17.7 % for cisplatin/5FU arm and 37.5 % for carboplatin/5FU arm (p-value=0.304). The median PFS was 7 months for cisplatin/5FU and 9 months for carboplatin/5FU (p-value=1.015). The median OS was 10 months for cisplatin/5FU arm and 12 months for carboplatin/5FU arm (p-value=0.110). There were 6 treatment-related deaths (6/41=14.6%), four in the carboplatin/5FU arm (4/24=16.7%) and 2 in the cisplatin/5FU arm (2/17=11.8%). Grade 3 and 4 hematologic toxicity was also more common with carboplatin/5FU group, this difference being predominantly due to grade 3-4 granulocytopenia (41.6% vs. 0), grade 3-4 anemia (37.5% vs. 0) and grade 3-4 thrombocytopenia (16.6% vs. 0).
CONCLUSIONS: Carboplatin/5FU is not inferior to cisplatin/5FU with regard to its efficacy. However, there was a high rate of treatment-related deaths with both regimens. A better alternative needs to be considered.
METHODS: This retrospective observational study was conducted in Penang General Hospital on 534 anemic solid cancer patients who were admitted between 2003 and 2009. The main statistical tests used were Chi-square test and Logistic regression test for categorical data. While for continues data the main statistical tests were Linear regression and correlation test. The significance of the result will be when the P<0.05, while the confidence interval for this study was 95%.
RESULTS: FEC, 5-FU+5-FU, Docetaxel and Cisplatin+ 5-FU regimen has strong association and correlation with anemia onset and severity. However the associations and correlations with anemia severity were stronger than those with the onset. Different doses of 5-FU, cyclophosphamide, docetaxel and cisplatin play a critical role in anemia onset and severity.
CONCLUSION: Monitoring and determination of hemoglobin levels for cancer patients treated with FEC, 5-FU+5-FU, Docetaxel, Cisplatin+ 5-FU specifically with high doses must be emphasized and a focus of particular attention.
PATIENTS AND METHODS: Patients who were treated with adjuvant taxane-based chemotherapy for early breast cancer stages I, II or III from 2007-2011 in UMMC were identified from our UMMC Breast Cancer Registry. The TRD and FN rates were then determined retrospectively from medical records. TRD was defined as death occurring during or within 30 days of completing chemotherapy as a consequence of the chemotherapy treatment. FN was defined as an oral temperature >38.5°C or two consecutive readings of >38.0°C for 2 hours and an absolute neutrophil count <0.5x109/L, or expected to fall below 0.5x109/L.
RESULTS: A total of 622 patients received adjuvant chemotherapy during this period. Of these patients 209 (33.6%) received taxane-based chemotherapy. 4 taxane-based regimens were used namely the FEC-D, TC, TAC and AC-PCX regimens. The commonest regimen employed was the FEC-D regimen accounting for 79.9% of the patients. The FN rate was 10% and there was no TRD.
CONCLUSION: Adjuvant taxane-based chemotherapy in UMMC for early breast cancer has a FN rate of 10%. Primary prophylactic G-CSF should be considered for patients with any additional risk factor for FN.
MATERIALS AND METHODS: Here we reported the initial experience of aflibercept / FOLFIRI in combination. We evaluated treatment-related adverse events (AEs), progression-free survival (PFS) and overall survival (OS).
RESULTS: The majority of the patients experienced gastrointestinal toxicity (grade 1-2), with diarrhea (52%), mucositis (52%), and nausea/vomiting (20%) being largely observed. Neutropenia (16%) and febrile neutropenia (8%) were common grade 3-4 hematological events. Aflibercept-related toxicity was managed as per practice guidelines. No grade 5 event was reported. Median PFS was 6.12 months (95% CI, 4.80-7.20) and OS was 12 months (95% CI, 9.80-14.18). The partial response (PR), stable disease (SD), and progressive disease (PD) rates were 25% (95% CI: 23.4-27.0), 37.5% (95% CI: 31.6-43.3), and 37.5% (95% CI: 22.5-52.5), respectively.
CONCLUSIONS: Aflibercept/FOLFIRI can be administered safely in a second line setting to Malaysian patients with mCRC, as the AEs experienced were generally reversible and manageable. The safety and efficacy outcomes were consistent with those observed in Western populations.
PATIENTS AND METHODS: APEC was a nonrandomized phase 2 trial conducted in the Asia-Pacific region. Patients (n = 289) received once-every-2-weeks cetuximab with investigator's choice of chemotherapy (FOLFOX or FOLFIRI). The primary end point was best confirmed overall response rate (BORR); progression-free survival (PFS) and overall survival (OS) were secondary end points. Early tumor shrinkage (ETS) and depth of response (DpR) were also evaluated.
RESULTS: In the KRAS wt population, BORR was 58.8%, median PFS 11.1 months, and median OS 26.8 months. Expanded RAS mutational analysis revealed that patients with RAS wt mCRC had better outcomes (BORR = 64.7%; median PFS = 13.0 months; median OS = 28.4 months). The data suggest that ETS and DpR may be associated with survival outcomes in the RAS wt population. Although this study was not designed to formally assess differences in outcome between treatment subgroups, efficacy results appeared similar for patients treated with FOLFOX and FOLFIRI. There were no new safety findings; in particular, grade 3/4 skin reactions were within clinical expectations.
CONCLUSION: The observed activity and safety profile is similar to that reported in prior first-line pivotal studies involving weekly cetuximab, suggesting once-every-2-weeks cetuximab is effective and tolerable as first-line therapy and may represent an alternative to weekly administration.
CASE REPORT: A 59-year-old man was diagnosed with acute promyelocytic leukaemia. Following this, he underwent all-trans retinoic acid (ATRA) based chemotherapy and achieved remission. Four years later, the disease relapsed and he was given idarubicin, mitoxantrone and ATRA followed by maintenance chemotherapy (ATRA, mercaptopurine and methotrexate). He achieved a second remission for the next 11 years. During a follow-up later, his full blood picture showed leucocytosis, anaemia and leucoerythroblastic picture. Bone marrow examination showed hypercellular marrow with trilineage dysplasia, 3% blasts but no abnormal promyelocyte. Fluorescence in-situ hybridisation (FISH) study of the PML/RARA gene was negative. Karyotyping result revealed complex abnormalities and monosomal karyotype (MK). A diagnosis of therapy-related myelodysplastic syndrome/myeloproliferative neoplasm with unfavourable karyotypes and MK was made. The disease progressed rapidly and transformed into therapy-related acute myeloid leukaemia in less than four months, complicated with severe pneumonia. Despite aggressive treatment with antibiotics and chemotherapy, the patient succumbed to the illness two weeks after the diagnosis.
DISCUSSION AND CONCLUSION: Diagnosis of t-MN should be suspected in patients with a history of receiving cytotoxic agents. Karyotyping analysis is crucial for risk stratification as MK in addition to complex aberrant karyotypes predicts unfavourable outcome. Further studies are required to address the optimal management for patients with t-MN.
METHODS: A prospective, non-randomised longitudinal study was conducted in two government integrated hospitals over an 8-month period. Early-stage breast cancer patients who were (1) either already using complementary and alternative medicine (CAM) or not and (2) who were on a regime of 5-fluorouracil, epirubicin, and cyclophosphamide were included in the study. Patients who agreed to receive CHM were assigned to receive individualised CHM prescriptions deemed suitable for the individual at a particular time. Those who were not willing to take Chinese herbal medicines (CHM) were assigned to the non-CHM control group. Blood profile and chemotherapy-induced AE were recorded whilst HRQOL assessment was done using the EORTC QLQ-C30 questionnaire on first, third, and sixth cycles.
RESULTS: Forty-seven patients [32 female vs. 1 male, p = 0.31; mean year of age: 52.2(SD = 7.6), p = 0.28)}] were recruited during the study period. Demographics of both groups were comparable. Fifty percent of respondents reported using some kind of CAM before chemotherapy. Diet supplements (40.6%) were the most common CAM used by the respondents. The study showed that patients using CHM had significantly less fatigue (p = 0.012), nausea (p = 0.04), and anorexia (p = 0.005) during chemotherapy. There were no significant differences in patients' HRQOL (p = 0.79). There were no AEs reported during the study.
CONCLUSION: The use of CHM as an adjunct treatment with conventional chemotherapy have been shown to reduce fatigue, nausea, and anorexia in breast cancer patients but did not reduce chemotherapy-associated hematologic toxicity. The sample size of this study was not powered to assess the significance of HRQOL between two groups of patients.
METHODS: In three double-blind phase 3 studies, patients receiving HEC or MEC were randomized 1:1 to receive oral rolapitant 180 mg or placebo prior to chemotherapy plus 5-hydroxytryptamine type 3 receptor antagonist and dexamethasone therapy. Patients completed the FLIE questionnaire on day 6 of cycle 1. Endpoints included FLIE total score, nausea and vomiting domain scores, and the proportion of patients with no impact on daily life (total score >108 [range 18-126]). We performed a prespecified analysis of the MEC/anthracycline-cyclophosphamide (AC) study and a post hoc analysis of two pooled cisplatin-based HEC studies.
RESULTS: In the pooled HEC studies, rolapitant significantly improved the FLIE total score (114.5 vs 109.3, p
METHODS: 79 patients with DLBCL (nodal, 59% and extranodal, 41%) treated with rituximab combined with cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) therapy were selected. Expression levels of BCR and linked signalling pathway molecules were inter-related with Lymph2Cx-based cell of origin (COO) types and overall survival (OS).
RESULTS: Activated B-cell (ABC) type DLBCL constituted 49% (39/79) compared with germinal centre B-cell (GCB) type DLBCL (29/79; 37%) and revealed poor prognosis (p=0.013). In ABC-DLBCL, high BTK expression exerted poor response to R-CHOP, while OS in ABC-DLBCL with low BTK expression was similar to GCB-DLBCL subtype (p=0.004). High LYN expression coupled with a poor OS for ABC-DLBCL as well as GCB-DLBCL subtypes (p=0.001). Furthermore, high coexpression of BTK/LYN (BTKhigh/LYNhigh) showed poor OS (p=0.019), which linked with upregulation of several genes associated with BCR repertoire and nuclear factor-kappa B pathway (p<0.01). In multivariate analysis, high BTK and LYN expression retained prognostic significance against established clinical predictive factors such as age, International Prognostic Index and COO (p<0.05).
CONCLUSIONS: Our data provide a clear association between high BCR activity in DLBCL and response to therapy in a distinct population. Molecular data provided here will pave the pathway for the provision of promising novel-targeted therapies to patients with DLBCL in Southeast Asia.
