Brief report of biweekly pemetrexed and gemcitabine in elderly patients with non-small cell lung cancer.

We examined a nonplatinum-based doublet chemotherapy regimen, pemetrexed and gemcitabine given on a biweekly (every 14 days) schedule, in patients older than 70 years with newly diagnosed advanced non-small cell lung cancer. The study was closed after nine patients were treated due to excess toxicity, primarily fatigue, and nonneutropenic infection. No responses were observed. Eight of the nine patients were hospitalized during therapy and seven discontinued treatment for reasons other than progressive disease. Median progression-free survival was 1.7 months, and median overall survival was 3.9 months. We found that biweekly pemetrexed and gemcitabine was too toxic in our cohort of elderly patients with newly diagnosed advanced non-small cell lung cancer.

Aggressiveness of care in a prospective cohort of patients with advanced NSCLC.

BACKGROUND: Optimal end of life care of patients with terminal cancer is poorly understood. In this study, the aggressiveness of care is described in a cohort of patients with newly diagnosed advanced nonsmall-cell lung cancer (NSCLC). METHODS: Patients within 8 weeks of diagnosis of stage IIIb (with effusions) or IV NSCLC were enrolled in a study to examine the feasibility of involving palliative care services early in the provision of cancer care. Participants received standard oncology treatment and integrated palliative care. All patients were followed prospectively to assess anticancer therapy usage, hospital admissions, hospice utilization, and location of death. RESULTS: At the time of analysis, 40/46 (87%) of enrolled patients had died, with a median length of follow-up of 29.3 months. Aggressive care measures in the final month of life included rates of anticancer therapy (40%), emergency department visits (48%), and hospital admissions (50%). Sixty-five percent of patients received hospice care before death, with a median length of stay of 16 days. Patients with heightened baseline anxiety and mood symptoms were more likely to receive anticancer therapy at the end of life compared with those without such symptoms. CONCLUSIONS: This study demonstrates the frequent use of aggressive measures at the end of life among patients with advanced NSCLC in a tertiary care center, as shown by the number of patients receiving anticancer therapy within 30 days of death and brief utilization of hospice services. Further research is needed to identify predictors of aggressive care and to develop interventions enhancing decision-making at the end of life.

Erlotinib plus bevacizumab in previously treated patients with malignant pleural mesothelioma.

BACKGROUND: We conducted a phase 2, multicenter, open-label study of erlotinib plus bevacizumab in patients with malignant pleural mesothelioma who had previously received 1 prior chemotherapy regimen. These agents have activity in non-small cell lung cancer, but their role in mesothelioma is unclear. The primary endpoint is response rate. Secondary endpoints include time to progression, survival, and toxicity. METHODS: Eligible patients with mesothelioma who had previously received 1 chemotherapy regimen were treated with erlotinib 150 mg per os daily and bevacizumab 15 mg/kg administered intravenously on Day 1 of a 21-day cycle. Treatment continued until disease progression or development of significant toxicity. Tumor response was assessed after every 2 cycles using previously established mesothelioma response criteria from Byrne and Nowak. RESULTS: Twenty-four eligible patients initiated therapy with erlotinib and bevacizumab between February 2004 and October 2006. There were no complete or partial responses, although 12 patients achieved stable disease for at least 2 cycles of treatment. The median time to progression was 2.2 months (95% confidence interval [CI], 1.4 months-5.9 months). The median survival was 5.8 months (95% CI, 2.8 months-10.1 months). The most common toxicities were rash and diarrhea. There were no treatment-related deaths, intracranial bleeding, or hemoptysis. CONCLUSIONS: The combination of erlotinib and bevacizumab was tolerated reasonably well, but there was no evidence of radiographic response. This study demonstrates the feasibility of conducting trials in mesothelioma patients who have failed first-line therapy. More therapeutic studies with effective agents are needed for these patients.

Phase II study: integrated palliative care in newly diagnosed advanced non-small-cell lung cancer patients.

PURPOSE: To assess the feasibility of early palliative care in the ambulatory setting in patients with newly diagnosed advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients were eligible if they had a performance status of 0 to 1 and were within 8 weeks of diagnosis of advanced NSCLC. Participants received integrated care from oncology and palliative care throughout the course of their disease. Participants were scheduled to meet with the palliative care team (PCT) and complete quality-of-life (QOL) and mood questionnaires monthly for 6 months. The study was deemed feasible if 64% of patients completed at least 50% of their scheduled visits and QOL assessments. RESULTS: Fifty-one patients were enrolled onto the trial. One died within 72 hours and was not assessable. Ninety percent (95% CI, 0.78 to 0.96) of study participants complied with at least 50% of the palliative care visits. Eight-six percent (95% CI, 0.73 to 0.94) of the participants met the full feasibility requirements by both meeting with the PCT and completing QOL assessments at least 50% of the time. QOL and mood analyses confirmed the high symptom burden in patients with newly diagnosed advanced NSCLC. At least 50% of participants experienced some degree of shortness of breath, cough, difficulty breathing, appetite loss, weight loss, or unclear thinking at their baseline assessment. More than one third of patients had a probable mood disorder at baseline. CONCLUSION: Integrated palliative and oncology care is feasible in ambulatory patients with advanced NSCLC.

Phase II clinical trial of chemotherapy-naive patients > or = 70 years of age treated with erlotinib for advanced non-small-cell lung cancer.

PURPOSE: This is a phase II, multicenter, open-label study of chemotherapy-naïve patients with non-small-cell lung cancer (NSCLC) and age > or = 70 years who were treated with erlotinib and evaluated to determine the median, 1-year, and 2-year survival. The secondary end points include radiographic response rate, time to progression (TTP), toxicity, and symptom improvement. PATIENTS AND METHODS: Eligible patients with NSCLC were treated with erlotinib 150 mg/d until disease progression or significant toxicity. Tumor response was assessed every 8 weeks by computed tomography scan using Response Evaluation Criteria in Solid Tumors. Tumor samples were analyzed for the presence of somatic mutations in EGFR and KRAS. RESULTS: Eighty eligible patients initiated erlotinib therapy between March 2003 and May 2005. There were eight partial responses (10%), and an additional 33 patients (41%) had stable disease for 2 months or longer. The median TTP was 3.5 months (95% CI, 2.0 to 5.5 months). The median survival time was 10.9 months (95% CI, 7.8 to 14.6 months). The 1- and 2- year survival rates were 46% and 19%, respectively. The most common toxicities were acneiform rash (79%) and diarrhea (69%). Four patients developed interstitial lung disease of grade 3 or higher, with one treatment-related death. EGFR mutations were detected in nine of 43 patients studied. The presence of an EGFR mutation was strongly correlated with disease control, prolonged TTP, and survival. CONCLUSION: Erlotinib monotherapy is active and relatively well tolerated in chemotherapy-naïve elderly patients with advanced NSCLC. Erlotinib merits consideration for further investigation as a first-line therapeutic option in elderly patients.

Outcomes of patients with advanced non-small cell lung cancer treated with gefitinib (ZD1839, "Iressa") on an expanded access study.

PURPOSE: To investigate the anti-tumor activity and toxicity of the epidermal growth factor receptor (EGFR) inhibitor gefitinib (ZD1839 or Iressa; AstraZeneca Pharmaceuticals, Wilmington, DE), in patients with advanced non-small cell lung cancer (NSCLC). METHODS: This was an open label, expanded access program (EAP) of oral gefitinib administered at 250 mg per day continuously until evidence of undue toxicity or disease progression. RESULTS: Two hundred consecutive patients with advanced NSCLC were enrolled in this study. The median number of prior chemotherapy regimens was 2 (range 0-6). One hundred seventy-two patients were treated with gefitinib; 23 expired from disease progression prior to treatment and 5 withdrew their consent. One hundred fifty-four patients are evaluable for toxicity; 8 (5.2%) experienced grade 3/4 toxicity; 2 patients discontinued therapy for grade 3 rash and one for grade 3 nausea. Of 172 patients evaluable for efficacy, 7 (4.1%; 95% CI; 1.7-8.2%) experienced a partial response (PR); 60 patients (34.9%) had stable disease (SD) as their best response. Median survival for all patients was 4.5 months (95% CI; 4.1-4.9 months). One-year survival was 29%. Significant independent prognostic factors associated with improved survival were female gender, good performance status (0/1), and adenocarcinoma histology. CONCLUSION: Gefitinib has anti-tumor activity, in a heterogeneous population of NSCLC patients treated on the EAP study. Treatment with gefitinib in this population is associated with a longer survival in women, those with good performance status and in patients with adenocarcinomas. These findings need to be further validated in additional clinical studies.

Induction docetaxel and carboplatin followed by weekly docetaxel and carboplatin with concurrent radiotherapy, then surgery in stage III non-small cell lung cancer: a Phase I study.

PURPOSE: To determine the maximum-tolerated dose of docetaxel (DOC) in combination with carboplatin (CAR) and thoracic radiotherapy (RT), in the setting of trimodality treatment of patients with stage III non-small cell lung cancer (NSCLC). EXPERIMENTAL DESIGN: Thirty-two patients with biopsy-proven stage IIIA (n = 20) or IIIB (n = 12) NSCLC were given two initial cycles of CAR (area under the curve = 6) and DOC (75 mg/m(2)), subsequent RT (54 Gy) with concurrent weekly CAR (area under the curve = 2), and DOC at six dose levels from 10 to 40 mg/m(2), then surgery if the patient's disease was resectable. RESULTS: Three patients did not complete induction computed tomography (CT). Twenty-nine patients received concurrent CT/RT. Fifteen patients were eligible for surgery. Dose-limiting toxicities occurred in 2 patients, at dose levels two (atrial fibrillation) and three (transaminitis). The maximum-tolerated dose, as defined by the protocol, was not reached, although grade 3 and 4 toxicities were encountered at all dose levels. The most common more than or equal to grades 3 toxicities were neutropenia, nausea, vomiting, and fatigue. Four patients (13.3%) responded to induction CT. Ten patients (38.5%) responded to CT/RT. Eight surgical patients (57.1%) were downstaged, including 3 pathologic complete responses. Median relapse free and overall survivals are 8.5 and 12 months. One-year and estimated 2-year survival rates are 56.3 and 34.3%. CONCLUSION: This new regimen for stage III NSCLC of induction CAR/DOC, then weekly CAR/DOC with concurrent RT followed by surgery, can be safely administered and offers encouraging results. DOC at 30 mg/m(2) in combination with CAR and RT is recommended for Phase II study.
