Systemic chemotherapy with doxorubicin, cisplatin and capecitabine for metastatic hepatocellular carcinoma

BackgroundAlthough numerous chemotherapeutic agents have been tested, the role of systemic chemotherapy for hepatocellular carcinoma (HCC) has not been clarified. New therapeutic strategies are thus needed to improve outcomes, and we designed this study with new effective drug combination.MethodsTwenty-nine patients with histologically-confirmed, metastatic HCC received a combination chemotherapy with doxorubicin 60 mg/m2 and cisplatin 60 mg/m2 on day 1, plus capecitabine 2000 mg/m2/day as an intermittent regimen of 2 weeks of treatment followed by a 1-week rest.ResultsThe median age was 49 years (range, 32–64) and 19 patients were hepatitis B virus seropositive. Child-Pugh class was A in all patients and 4 had Zubrod performance status of 2. The objective response rate was 24% (95% CI 9–40) with 6 stable diseases. The chemotherapy was generally well tolerated despite one treatment-related death.ConclusionCombination chemotherapy with doxorubicin, cisplatin and capecitabine produced modest antitumor activity with tolerable adverse effects in patients with metastatic HCC.

Paclitaxel versus docetaxel for advanced gastric cancer : a randomized phase II trial in combination with infusional 5-fluorouracil

Taxanes have clearly demonstrated activities against gastric cancer. We compared the combination of paclitaxel plus 5-fluorouracil (5-FU) (PF) with docetaxel plus 5-FU (DF) as first-line chemotherapy in patients with measurable metastatic gastric cancer. Seventy-seven patients were randomly assigned to receive paclitaxel 175 mg/m2 or docetaxel 75 mg/m2 on day 1, in combination with 5-FU 500 mg/m2 continuous infusion on days 1–5. Treatment was repeated every 3 weeks. Of 314 chemotherapy cycles delivered (median 5 in both groups), dose reduction was required more frequently in the DF group, being 9 and 19%, respectively (P<0.01). PF was associated with, although statistically insignificant, substantially less grade 3 or 4 toxicities than DF (68 versus 85%; P=0.09). Global quality of life was similar in both groups, but substantive differences in many symptom scores including pain, dyspnea, constipation and diarrhea favored PF. There were no significant differences in therapeutic efficacy between PF and DF with respect to response rate (42 versus 33%, respectively; P=0.53), and failure-free (3.6 versus 4.2 months; P=0.92) and overall survival (9.9 versus 9.3 months; P=0.42). Both PF and DF appear to have efficacy against metastatic gastric cancer, with different, but acceptable, safety profiles.

Two Cases of Interstitial Pneumonitis Caused by Rituximab Therapy

Rituximab, a chimeric monoclonal antibody directed against CD20, has become a part of the standard therapy for patients with non-Hodgkins lymphoma either in combination with other drugs or as a single agent. The CD20 antigen is expressed on 95% of B-cell lymphoma cells and normal B-cells but, is not found on precursor B-cells or stem cells. Rituximab is now approved for patients with diffuse large B-cell lymphoma when combined with standard CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine and prednisone) or patients with follicular lymphoma who have failed first line chemotherapy. The monoclonal antibody is generally well tolerated. Most of the adverse events are infusion-associated, mild to moderate non-hematological toxicities. Severe respiratory adverse events have been infrequent. Here, we report two patients with non-Hodgkins lymphoma in whom interstitial pneumonitis developed with rituximab therapy.

Epstein-Barr Virus -Positivity in Tumor has no Correlation with the Clinical Outcomes of Patients with Angioimmunoblastic T-cell Lymphoma

Background/Aims Epstein-Barr virus (EBV) is involved in the pathogenesis of angioimmunoblastic T-cell lymphoma (AILT), but its precise role and prognostic impact are not clear. This study aimed to evaluate the incidence of EBV-postitivity in the tumor and bone marrow (BM) samples from AILT patients, and their correlations with the clinical variables and patient survival. Methods Seventy AILT cases were identified over a period of 8 years. Twenty seven cases were investigated for their EBV tumor status, and 10 BM samples of these patients were investigated for their EBV status with using in situ hybridization (ISH). EBV PCR was performed for the BM mononuclear cells in 8 cases. Results Among the 27 tumor specimens, ten (37%) were EBV-positive. Only CD20-negativity in tumor correlated with the EBV-positivity (p=0.035). In 13 (48%) patients, gross tumor involvement was recognized by hematoxylin-eosin staining at the time of diagnosis. Among the 10 patients who had additional BM slides available, there were 3 with BM involvement, and none showed EBV positive results on ISH. EBV PCR of the BM mononuclear cells revealed one-positive case among 8 patients. This patient was negative for both BM involvement and EBV ISH. The median overall survival of the 25 treated patients was 48.9 months (95% CI: 18.6~79.2 months). Neither overall survival nor progression-free survival was related with EBV-positivity of the tumor. Conclusions EBV-positivity of tumor had no impact on the prognosis of AILT patients.
