AbstractBACKGROUNDHepatitis B virus (HBV) infection is a common disease in China. Severe hepatitis is a well recognized complication in HBV carriers with malignant disease who receive cytotoxic chemotherapy. The objective of the current study was to assess the value of antiviral lamivudine for reducing the incidence and severity of hepatitis in HBV carriers with lymphoma who receive chemotherapy.METHODSTwo groups were compared in this nonrandomized study. The prophylactic lamivudine group was comprised of 40 patients who received oral lamivudine at a dose of 100 mg daily before and until at least 8 weeks after they discontinued chemotherapy. The historic control group was comprised of 116 patients who received chemotherapy without lamivudine. The incidence and severity of hepatitis and other adverse clinical outcomes were compared between the two groups. Significant prognostic factors for the development of hepatitis were determined based on data derived from the control group.RESULTSThe two groups were comparable in most clinical baseline characteristics, including gender distribution, age, tumor types, primary treatment, hepatitis Be antigen status, and the use of anthracyclines or/and prednisone. In the prophylactic lamivudine group, there was significantly less incidence of hepatitis (17.5% vs. 51.7% in the control group; P = 0.000); less severe hepatitis (according to World Health Organization [WHO] criteria) (10% with Grade 1, 5% with Grade 2, and 2.5% with Grade 3 hepatitis vs. 3.4% with Grade 1, 12.1% with Grade 2, 12.9% with Grade 3, and 23.3% with Grade 4 hepatitis in the control group; P = 0.000); and less disruption of chemotherapy (10.0% vs. 37.1% in the control group; P = 0.001). The overall mortality as a result of hepatitis in the prophylactic lamivudine group was lower compared with that in the control group, but the difference was not statistically significant (0.0% vs. 5.2%; P = 0.163). In the control group, the factor associated with a greater risk of developing hepatitis was the use of prednisone. In the prophylactic lamivudine group, 1 of 40 patients (2.5%) developed hepatitis that was attributable to HBV reactivation. Further examination demonstrated that this single patient had a variation of HBV with YMDD mutations after the use of lamivudine for 9.2 months.CONCLUSIONSThe results of the current study confirmed previous reports that lamivudine prophylaxis significantly reduced the incidence and severity of hepatitis in HBV carriers who were receiving chemotherapy for lymphoma. The chemotherapy disruption rate as a result of severe hepatitis also was decreased significantly. Cancer 2006. © 2006 American Cancer Society.
Survival rates and patterns of care for patients diagnosed with supratentorial low‐grade gliomas
Authors: Claus Elizabeth B. , Black Peter M. 
Published: February 2006

AbstractBACKGROUNDDetailed population‐based estimates of long‐term survival as well as patterns of care for patients with low‐grade gliomas examined by age at diagnosis, gender, and race have not been widely available.METHODSTime to death was examined among 2009 individuals diagnosed with a supratentorial low‐grade glioma and reported to the Surveillance, Epidemiology, and End Results (SEER) program of the National Cancer Institute from 1973–2001 using Kaplan–Meier estimation. A Cox proportional hazards model was used to assess the effect of age at diagnosis, race, gender, histology, anatomic location within the brain, first course of treatment, and year of diagnosis upon this risk.RESULTSThe cumulative 5‐, 10‐, 15‐ and 20‐year survival rates among all individuals initially diagnosed with a supratentorial low‐grade glioma were 59.9% (95% confidence interval [95% CI], 57.6–62.2); 42.6% (95% CI, 39.9–45.2); 31.9% (95% CI, 29.0–34.8); and 26.0% (95% CI, 22.7–29.2), respectively. Improved survival was significantly associated with female gender (hazard ratio [HR], 0.84; 95% CI, 0.74–0.95), younger age, white race (HR, 0.70; 95% CI, 0.54–0.93), histology, and later year of diagnosis. Surgical treatment was associated with increased survival. The use of radiation therapy as a first course of treatment for these lesions has significantly decreased over time with the majority of patients receiving only surgery as a first course of treatment.CONCLUSIONSData for patients diagnosed with low‐grade gliomas revealed increasing survival times over the past 25 years with a subset of patients surviving for decades. Differences in survival by race, gender, histology, and first course of treatment were appreciated. These data suggested that the clinical course of low‐grade glioma for some patients may be more encouraging than previously perceived and that the identification of this group of patients may allow refinement of current treatment protocols.

AbstractBACKGROUNDConventional systemic chemotherapy for metastatic urothelial carcinoma (UC) such as methotrexate, vinblastine, doxorubicin, and cisplatin (M‐VAC) or cisplatin, methotrexate, and vinblastine (CMV) is associated with significant dose‐limiting toxicities and even treatment‐related death. The authors developed a regimen that was designed to maintain efficacy, while reducing toxicities.METHODSBetween January 1998 and July 2003, 35 patients (median age, 71 yrs) with metastatic UC were treated with 4‐week cycles of P‐HDFL (cisplatin 35 mg/m2, high‐dose 5‐fluorouracil [5‐FU] 2,600 mg/m2, and leucovorin 300 mg/m2, on Days 1 and 8, all given by 24‐hr infusion). On Day 15, only HDFL was given again.RESULTSAmong the 32 patients treated with ≥ 2 cycles, 9 (28.1%) and 11 (34.4%) were complete and partial responders, respectively, with an overall response rate of 62.5% (95% confidence interval [CI], 45.9–79.2%). The median overall and progression‐free survival was 12.3 months (95% CI, 8.2–16.4 mos) and 10.5 months (95% CI, 8.4–12.6 mos), respectively. Toxicity in a total of 121 courses (mean, 3.5 per patient) was modest, with WHO Grade 3 or 4 leukopenia and thrombocytopenia noted in only 1 and 0 patients, respectively. Grade 3 or 4 nausea, vomiting, mucositis, and diarrhea were noted in 3, 2, 0, and 2 patients, respectively. In general, patients tolerated the regimen very well.CONCLUSIONSP‐HDFL is a moderately active and considerably low‐toxic regimen for metastatic UC. The excellent toxicity profile makes it a viable option for patients with poor general conditions. To reach any conclusion, randomized trials comparing P‐HDFL with traditional cisplatin‐based regimens are necessary. Cancer 2006. © 2006 American Cancer Society.

AbstractBACKGROUNDPoorly differentiated thyroid carcinomas (PDTC) occupy an intermediate position at the prognostic level on the spectrum of thyroid carcinoma progression. However, their histologic definition is controversial. The objective of the current study was to assess the prognostic significance of PDTC defined on the basis of mitosis and necrosis and search for prognostic markers within this group of tumors that are predictive of overall survival (OS) and progression‐free survival (PFS).METHODSPDTC was defined as thyroid carcinoma with follicular cell differentiation at the histologic and/or immunohistochemical levels and displaying tumor necrosis and/or ≥ 5 mitoses per 10 high‐power fields (×400). Retrospective chart review and microscopic examination identified 58 patients with primary tumors meeting the above criteria and seen at the Memorial Sloan‐Kettering Cancer Center between 1992 and 2004. These 58 patients were analyzed for various histologic, clinical, and imaging parameters. Each parameter was correlated with OS and PFS.RESULTSOf the 58 patients studied, 22 (38%) patients died of disease with a 5‐year OS rate of 60%. Forty‐three of the 58 patients (74%) developed disease recurrence or disease progression, with a 5‐year PFS rate of 25%. The median follow‐up for the entire patient population was 42.6 months (range, 4–205 mos). A tumor size > 4 cm was found to be correlated with a decreased PFS time (P < 0.001). Those tumors with a capsule demonstrated a significantly improved OS compared with unencapsulated tumors (P = 0.001). The extent of capsular invasion was found to be a significant adverse factor for PFS (P = 0.05). The presence of extrathyroid extension into perithyroid soft tissue was found to be correlated with a decreased OS (P = 0.001) and PFS (P = 0.004). Of 27 patients with distant metastasis, 19 (70%) had concentrated radioactive iodine (RAI) at their metastatic sites. On multivariate analysis, extrathyroid extension and tumor size emerged as the only significant variables in predicting PFS (P = 0.04 and P = 0.01, respectively) whereas extrathyroid extension was found to be the sole independent prognostic factor for OS (P = 0.01). Growth pattern and cell type did not appear to influence outcome.CONCLUSIONSPDTC defined on the basis of mitosis and necrosis constitutes a group of tumors that is more aggressive and homogeneous than PDTC defined by growth pattern. Within this group of patients, microstaging (tumor size, the extent of capsular invasion, and, especially, extrathyroid extension), and not growth pattern or cell type, is able to stratify patients into different prognostic categories. RAI uptake occurs in a significant number of patients with PDTC. Cancer 2006. © 2006 American Cancer Society.
