A multicenter, phase II trial of everolimus in locally advanced or metastatic thyroid cancer of all histologic subtypes.

BACKGROUND: This phase II study investigated the efficacy and safety of everolimus, an inhibitor of mammalian target of rapamycin (mTOR), in locally advanced or metastatic thyroid cancer. PATIENTS AND METHODS: Patients with thyroid cancer of any histology that was resistant or not appropriate for (131)I received everolimus 10 mg daily orally until unacceptable toxicity or disease progression. The primary end point was disease control rate [partial response (PR) + stable response ≥12 weeks]. Secondary end points included response rates, clinical benefit (PD + durable stable disease (SD)], progression-free survival (PFS), overall survival, duration of response, and safety. RESULTS: Thirty-eight of 40 enrolled patients were evaluable for efficacy. The disease control rate was 81% and two (5%) patients achieved objective response; their duration of response was 21+ and 24+ weeks. Stable disease (SD) and progressive disease was reported in 76% and 17% of patients, respectively. Seventeen (45%) patients showed durable SD (≥24 weeks) and clinical benefit was reported in 19 (50%) patients. Median PFS was 47 weeks [95% confidence interval (CI) 14.9-78.5]. Calcitonin, CEA, and thyroglobulin concentrations were ≥50% lower than baseline in three (30%) and four (44%) patients with medullary thyroid cancer and five (33%) patients with PTC, respectively. The most common treatment-related adverse events were mucositis (84%), anorexia (44%), and aspartate transaminase/alanine transaminase elevation (26%). CONCLUSIONS: Everolimus had a limited activity with low response rate in locally advanced or metastatic thyroid cancer. Reasonable clinical benefit rate and safety profile may warrant further investigation. CLINICALTRIALSGOV NUMBER: NCT01164176.

Significance of smoking history and FDG uptake for pathological N2 staging in clinical N2-negative non-small-cell lung cancer.

BACKGROUND: This study was conducted to evaluate whether smoking history and the standardized uptake value (SUV) of 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG) uptake are associated with unexpected pathological N2 status (pN2) in non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: We analyzed the data of 220 patients who underwent surgical resection with clinical N2-negative status on computed tomography (CT) and positron emission tomography (PET)-CT. The maximum SUV of primary tumor was chosen for logistic analysis. RESULTS: Seventy-two patients (33%) had never smoked. The SUV ranged from 1.0 to 29.0 (median 9.1). In univariate analysis, adenocarcinomas (P = 0.019), female gender (P = 0.010), N1 on CT (P = 0.025), and N1 PET-CT (P = 0.001) were associated with a high probability of pN2. The proportion of pN2 in never smokers was higher than in ever smokers (26% versus 10% respectively; P = 0.002). The SUV remained on a multivariate logistic model (odds ratio 1.1; 95% confidence interval 1.0-1.2; P = 0.010) and it had a better predictive value in never smokers than in ever smokers (P = 0.017). CONCLUSIONS: This study indicates an association between smoking history and pN2 in clinically negative N2 NSCLC. The different roles of FDG uptake were also suggested based on smoking history.

Efficacy of chemotherapy as a first-line treatment in ocular adnexal extranodal marginal zone B-cell lymphoma.

BACKGROUND: Radiotherapy is commonly used as a first-line treatment for localized ocular adnexal extranodal marginal zone B-cell lymphoma (EMZBL), despite its ophthalmologic complications. This study was undertaken to analyze the efficacy of first-line chemotherapy in treating EMZBL. Chemotherapy was followed by radiotherapy only in recurrent cases. PATIENTS AND METHODS: Twenty-one patients with histologically confirmed EMZBL were treated with combination of cyclophosphamide, vincristine, and prednisolone (CVP). Radiotherapy was given to CVP failure cases. RESULTS: CVP alone resulted in overall response rate of 100% [complete remission (CR), 76.2%]. After a median follow-up of 58 months, 14 (66.7%) of 21 cases were disease free with CVP alone, while seven cases showed disease progression, including two extra-orbital and five local failures. Radiotherapy was delivered to five local failure cases, who subsequently achieved CR with late ophthalmologic complications. There were tolerable adverse events associated with CVP. CONCLUSIONS: Front-line CVP, in conjunction with radiotherapy in recurrent cases, is effective and well tolerated in patients with localized ocular adnexal EMZBL.

Phase II Trial of Vinorelbine and Cisplatin Chemotherapy in Advanced Non-Small Cell Lung Cancer.

PURPOSE: Platinum-based chemotherapy has conferred a modest but significant survival benefit and the introduction of newer drugs has led to achieve higher response rate in patients with advanced non-small cell lung cancer (NSCLC). We performed a phase II trial in order to evaluate the efficacy and toxicity of combination chemotherapy with vinorelbine (Navelbine) and cisplatin in advanced NSCLC. MATERIALS AND METHODS: Patients with previously untreated, unresectable stage IIIB or IV NSCLC with measurable lesion (s) were eligible for entry into the study. NP chemotherapy consisted of intravenous vinorelbine 25 mg/m2, on day 1 and 8, and intravenous cisplatin 80 mg/m2 on day 1; this cycle was repeated every three weeks. RESULTS: A total of 33 patients were enrolled in the study between July 1999 and Feb 2000. Of the 30 patients deemed eligible for analysis, thirteen patients achieved a partial response and thirteen showed a stable disease. The overall response rate was 43.3%. The median duration of response was 5.7 months (95% CI: 2.8~8.5 months). The median time to progression was 7.6 months (95% CI: 5.5~9.7 months) and the overall median survival time was 15.1 months (95% CI: 9.8~20.4 months) in the intent-to-treat analysis. Chemotherapy-related grade 3 or 4 toxicities were anemia in 1.5%, leukopenia in 4.5%, nausea/vomiting in 2.3%, alopecia in 13.3%, and neurotoxicity in 3.3%. CONCLUSION: The combination of vinorelbine and cisplatin chemotherapy seems to be active and fairly tolerable in patients with advanced NSCLC.
