RESUMO

Treatment of unresectable recurrent hepatocellular carcinoma (HCC) in patients who recur after resection or orthotopic liver transplantation (OLT) remains a clinical challenge. One option is sorafenib, although little is known about its safety and tolerance in this unique patient population; therefore, we analyzed patients who underwent prior surgical resection and/or OLT and were treated with sorafenib in US cohort of GIDEON registry. In US, 645 patients were enrolled; 553 for intent to treat and 563 for safety. Data were analyzed in the safety population of 479 patients no surgery and 56 for resection or OLT. Forty-one patients underwent resection prior to the initiation of sorafenib, 15 patients had previously received an OLT, and 6 patients had both resection and OLT. Initial low starting doses (400 mg/day) were observed for more patients with prior OLT (71%) than prior resection (36%), resection and OLT (50%), concomitant OLT (25%), and no surgery (36%). Most AEs occurred in the first 4 weeks of treatment. Drug-related AEs were higher in patients with prior resection (87%), prior OLT (100%), or both (100%) than in patients with concomitant OLT (63%) or no surgery (70%). However, incidence of AEs resulting in permanent discontinuation were similar in all groups (19-38%).

RESUMO

BACKGROUND: Global Investigation of Therapeutic Decisions in Hepatocellular Carcinoma and of Treatment with Sorafenib (GIDEON) is a worldwide, prospective, non-interventional study to evaluate the safety of sorafenib in a variety of patient subsets. METHODS: Eligible patients had unresectable hepatocellular carcinoma for whom the decision had been made to treat with sorafenib. Treatment strategies were instituted at the physician's discretion. Patient and disease characteristics, treatment practices, incidences of adverse events (AEs), and overall survival were collected. RESULTS: In the United States, 563 patients were evaluable for safety. Subgroup analysis was performed for patients who underwent transarterial chemoembolization (TACE) prior to the initiation of sorafenib (group A, n=158), after the initiation of sorafenib only (group B, n=29), both (group C, n=38), or did not undergo TACE (n=318). Patient demographics were similar across the groups. In group A, 29% had Child-Pugh score B or C at diagnosis, and 19% had Barcelona Clinic Liver Cancer tumor stage C or D. In group B, 48% had Child-Pugh score B or C at study entry, and 31% had BCLC stage C or D. The majority of patients in all groups initially received full-dose sorafenib. Incidences of grade ≥3 drug-related AEs were 30%, 17%, and 16% in groups A, B, and C, respectively, and 22% in patients who did not undergo TACE. No new safety signals emerged. CONCLUSIONS: The results from GIDEON reaffirm that sorafenib can be safely used in the context of TACE.

RESUMO

BACKGROUND: Transcatheter arterial chemoembolization (TACE) has been used to curtail tumor vasculature and delay tumor progression in hepatocellular carcinoma (HCC). We conducted a phase I trial to evaluate the efficacy and toxicity of thalidomide when combined with TACE in patients with advanced HCC. METHODS: Between June 2000 and November 2003, 56 patients with unresectable HCC and amenable to TACE were enrolled. The starting dose of thalidomide was 200 mg/day and was escalated every 2 weeks as tolerated to a maximum dose of 1,000 mg/day. Dose reductions and discontinuation were determined by toxicity. TACE was performed 4 weeks after initiation of thalidomide therapy and repeated as necessary. RESULTS: Overall, 47 and 55 patients were evaluable for response and toxicity, respectively; the median dose of thalidomide given was 200 mg/day. Three patients (6.38%) patients achieved complete responses, whereas 10 (21.3%) had partial responses, for an overall response rate of 27.7%, and 27 (57.5%) had stable disease. Median progression-free survival was 7 months (95% confidence interval [CI]: 5-10 months), and median OS was 21 months (95% CI: 16-28 months) (Fig. 1). Fatigue and lethargy (49.1%), constipation (47.3%), and nausea (43.6%) were common. Grade 3-4 toxicities consisted mostly of increased aspartate aminotransferase (43.6%) and elevated alanine aminotransferase (38.2%) (Table 1). CONCLUSION: Thalidomide and TACE were commonly associated with nonhematologic side effects, with fatigue and constipation being prominent. With a lack of clear therapeutic benefit, this combination is unlikely to be pursued for HCC.

RESUMO

Despite the established efficacy of sorafenib in advanced hepatocellular carcinoma (HCC), a significant number of sorafenib-treated patients experience disease progression. Current guidelines recommend either best supportive care or clinical trial enrollment for this population. As such, there remains an unmet need for tolerable, life-prolonging strategies in the second-line setting. New information regarding the molecular pathogenesis of resistance to antiangiogenic therapy and positive post-progression experience with antiangiogenics in other tumor types has led to trials investigating the effect of continued use of sorafenib, alone or combined with other agents. Trials investigating the effect of switching from sorafenib to alternate antiangiogenic agents, phosphatidylinositol 3 kinase/AKT/mammalian target of rapamycin inhibitors, or cMet inhibitors are also underway. As these data emerge, clinicians may consider a new paradigm for managing advanced HCC. This article briefly reviews the mechanisms of disease resistance to antiangiogenic therapy as a vehicle for discussing clinical strategies to prolong survival in patients with advanced HCC that are currently employed at our institutions or are under investigation. Key ongoing trials investigating the use of molecularly targeted therapies in patients with progressive disease are also highlighted.

RESUMO

BACKGROUND: Anaplastic thyroid carcinoma (ATC) is rare but is one of the most aggressive and lethal human malignancies. Cytologically, ATC has a variable morphologic appearance, including squamoid, giant, spindled and pleomorphic cells. The coexistence of ATC and differentiated or poorly differentiated thyroid carcinoma has been described and usually is diagnosed when the disease is locally advanced. CASE: We describe a case of surgically resectable, encapsulated, well-circumscribed ATC occurring in association with a better differentiated follicular carcinoma diagnosed by fine needle aspiration in a patient exposed to external ionizing radiation. CONCLUSION: Encapsulated variants of anaplastic carcinoma can be seen in association with lower grade thyroid carcinoma such as follicular carcinoma. Accurate diagnosis is dependent on adequate sampling.

RESUMO

PURPOSE: To determine the clinical and biologic effects of bevacizumab, an anti-vascular endothelial growth factor (VEGF) monoclonal antibody, in unresectable hepatocellular carcinoma (HCC). PATIENTS AND METHODS: Adults with organ-confined HCC, Eastern Cooperative Oncology Group performance status of 0 to 2, and compensated liver disease were eligible. Patients received bevacizumab 5 mg/kg (n = 12) or 10 mg/kg (n = 34) every 2 weeks until disease progression or treatment-limiting toxicity. The primary objective was to determine whether bevacizumab improved the 6-month progression-free survival (PFS) rate from 40% to 60%. Secondary end points included determining the effects of bevacizumab on arterial enhancement and on plasma cytokine levels and the capacity of patients' plasma to support angiogenesis via an in vitro assay. RESULTS: The study included 46 patients, of whom six had objective responses (13%; 95% CI, 3% to 23%), and 65% were progression free at 6 months. Median PFS time was 6.9 months (95% CI, 6.5 to 9.1 months); overall survival rate was 53% at 1 year, 28% at 2 years, and 23% at 3 years. Grade 3 to 4 adverse events included hypertension (15%) and thrombosis (6%, including 4% with arterial thrombosis). Grade 3 or higher hemorrhage occurred in 11% of patients, including one fatal variceal bleed. Bevacizumab was associated with significant reductions in tumor enhancement by dynamic contrast-enhanced magnetic resonance imaging and reductions in circulating VEGF-A and stromal-derived factor-1 levels. Functional angiogenic activity was associated with VEGF-A levels in patient plasma. CONCLUSION: We observed significant clinical and biologic activity for bevacizumab in nonmetastatic HCC and achieved the primary study end point. Serious bleeding complications occurred in 11% of patients. Further evaluation is warranted in carefully selected patients.

RESUMO

PURPOSE: To evaluate thalidomide in advanced hepatocellular carcinoma (HCC) and to evaluate combined thalidomide and low-dose interferon-alpha2a (IFN-alpha2a) after tumor progression on thalidomide. Systemic therapy is minimally effective in HCC and tumor angiogenesis is a potential therapeutic target. PATIENTS AND METHODS: Patients with unresectable HCC were eligible if they had preserved hepatic and renal function. The initial thalidomide dosage was 200 mg daily and was adjusted for toxicity. Upon progression, patients could continue thalidomide with additional low-dosage (one million units twice daily) IFN-alpha2a. RESULTS: Thirty-eight enrolled patients were predominantly hepatitis C virus infected (53%), Child-Pugh class A (79%), and Eastern Cooperative Oncology Group performance status 0-1 (92%); 60% had extrahepatic metastasis. Confirmed disease control was seen in seven patients (18%) and included one complete and one partial response (5% response rate). The median progression-free survival was 2.1 months, and median overall survival was 5.5 months. Tumor invasion of the portal vein or vena cava, large (>10 cm) tumor, and younger age were associated with shorter overall survival. Toxicity included fatigue in 74% of patients. Six patients stopped therapy because of side effects, including two patients (5%) with grade 4 arteriothrombotic events. Five patients continued thalidomide upon progression with the addition of IFN-alpha2a; there was no disease control and 80% had grade 3 toxicity. CONCLUSIONS: Thalidomide is not well tolerated and confers limited disease control in advanced HCC. Combination thalidomide and low-dose IFN-alpha2a is neither safe nor efficacious in this population.

RESUMO

Breast involvement with non-Hodgkin's lymphoma (NHL) is rare. Patients with AIDS have an increased incidence of NHL, often with high-grade histology, extranodal presentation and aggressive clinical course. Lymphoma of the breast in patients with HIV-1 infection has not been reported. We reviewed our tumor registry database of all AIDS-associated NHL and report on the clinical presentation and long-term outcome of 3 patients with AIDS who presented with lymphomatous involvement of the breast.

RESUMO

OBJECTIVE: To determine utility of practice of chest computed tomography (CCT) and bone scan (BS) in patients with early-stage hepatoma evaluated for transplantation (LT). SUMMARY BACKGROUND DATA: Consensus-based policy mandates routine CCT and BS in LT candidates with hepatoma. No data exist either to support or refute this policy. METHODS: From January 1999 to December 2002, stages I and II hepatoma patients evaluated at 4 centers were included. Scan interpretation was positive, indeterminate, or negative. Outcomes of evaluation and transplantation were compared between groups based on scans. Total charges incurred were derived from mean of charges at the centers. RESULTS: One hundred seventeen stages I and II patients were evaluated. None had positive scans, 78 had negative, 29 had at least 1 indeterminate, and 10 did not have 1 or both scans. Twelve patients were declined listing, 6 from progression of hepatoma but none from CCT or BS findings. Two listed patients were delisted for progression of the hepatoma. Proportion of patients listed, transplanted, clinical and pathologic stage of hepatoma, and recurrence after LT were similar in groups with negative and indeterminate scans. Indeterminate scans led to 6 invasive procedures, 1 patient died of complications of a mediastinal biopsy, and none of the 6 showed metastases. Charges of $2933 were generated per patient evaluated. CONCLUSIONS: Positive yield of routine CCT and BS in patients with hepatoma is very low despite substantial charges and potential complications. CCT and BS performed only when clinically indicated will be a more cost-effective and safer approach.
