    ABSTRACT: Lung cancer is the leading cause of cancer death in men and women, and current second-line chemotherapy regimens yield relatively poor response and survival rates. We hypothesized that the combination of weekly docetaxel (D) and gemcitabine (G) would show activity in the second-line setting. We therefore conducted a phase II trial evaluating this regimen in patients with relapsed or progressive non-small cell lung cancer (NSCLC) after first-line platinum-based therapy. Patients with recurrent NSCLC, adequate physiologic indices, and exposure to one prior platinum-based regimen were eligible. Docetaxel 40 mg/m intravenous (IV) and gemcitabine (G) 800 mg/m IV weekly were administered on day 1 and 8 every 21 days. In the absence of dose-limiting toxicity, G was escalated on an intrapatient basis to 1 g/m/wk. The primary endpoint was response rate (RR); event-free (EFS) and overall survival were secondary endpoints. Thirty-five patients (median age 61 years; 20 [57%] male) were accrued. Most (88%) had previously received carboplatin/paclitaxel, 31.4% in combination with a third investigational agent, more than half (57.1%) had prior radiation. The median number of cycles was four. RR was 23%. Median EFS was 5.7 months and median overall survival was 12.5 months. Patients who had their cancer diagnosed more than or equal to 12 months before entering the trial had superior EFS (13.7 months versus 4.8 months). Toxicity was acceptable. There were no treatment-related deaths. A nonplatinum doublet with GD is feasible and effective in the treatment of recurrent, platinum-exposed NSCLC patients. RR and survival are promising.

    ABSTRACT: Patients with advanced, incurable thyroid cancer not amenable to surgery or radioactive iodine ((131)I) therapy have few satisfactory therapeutic options. This multi-institutional study assessed the activity and safety of axitinib, an oral, potent, and selective inhibitor of vascular endothelial growth factor receptors (VEGFR) 1, 2, and 3 in patients with advanced thyroid cancer. Patients with thyroid cancer of any histology that was resistant or not appropriate for (131)I were enrolled onto a single-arm phase II trial to receive axitinib orally (starting dose, 5 mg twice daily). Objective response rate (ORR) by Response Evaluation Criteria in Solid Tumors was the primary end point. Secondary end points included duration of response, progression-free survival (PFS), overall survival, safety, and modulation of soluble (s) VEGFR. Sixty patients were enrolled. Partial responses were observed in 18 patients, yielding an ORR of 30% (95% CI, 18.9 to 43.2). Stable disease lasting > or = 16 weeks was reported in another 23 patients (38%). responses were noted in all histologic subtypes. Median PFS was 18.1 months (95% CI, 12.1 to not estimable). Axitinib was generally well tolerated, with the most common grade > or = 3 treatment-related adverse event being hypertension (n = 7; 12%). Eight patients (13%) discontinued treatment because of adverse events. Axitinib selectively decreased sVEGFR-2 and sVEGFR-3 plasma concentrations versus sKIT, demonstrating its targeting of VEGFR. Axitinib is a selective inhibitor of VEGFR with compelling antitumor activity in all histologic subtypes of advanced thyroid cancer.

    ABSTRACT: In a previous randomized phase II trial evaluating carboplatin and paclitaxel with or without bevacizumab in patients naive to chemotherapy with advanced non-small-cell lung cancer (NSCLC), median survival ranged from 53 weeks to 76 weeks. Sudden life-threatening hemoptysis occurred in 6 of 66 patients receiving chemotherapy and bevacizumab; 4 episodes were fatal, all in patients with squamous cell histology. Squamous histology and bevacizumab therapy were the only factors associated with life-threatening hemorrhage. ECOG 4599 (Eastern Cooperative Oncology Group 4599), a randomized phase III trial of paclitaxel and carboplatin with or without bevacizumab ultimately excluded patients with squamous histology as well as brain metastases, ongoing therapeutic anticoagulation/nonsteroidal anti-inflammatory drugs, antecedent hemoptysis, and performance status (PS) of 2. We performed a retrospective analysis during a defined period to determine the proportion of patients with newly evaluated advanced NSCLC seen at Fox Chase Cancer Center (FCCC) who would have been eligible for ECOG 4599. We reviewed new thoracic oncology patient visits (n = 260) at FCCC scheduled with 6 medical oncologists from March 1, 2002, through August 8, 2002. Forty-five patients had histology that made them ineligible (8 mesothelioma, 6 small-cell, 5 mixed histology, and 26 non-lung cancers). Of the remaining 215 patients with NSCLC, 8 had incomplete charts for review and 7 had stage I, 8 stage II, and 43 stage III NSCLC. Of the remaining 149 patients, 33 had received chemotherapy previously. Of the remaining 116, only 34 (29.3%) were eligible. Of 82 ineligible patients, 21 (25.6%) had PS > or = 2, 20 (24.3%) had central nervous system (CNS) metastases, 11 (13.4%) had squamous histology, 9 (10.9%) had therapeutic anticoagulation, and 21 (25.6%) had > or = 2 criteria (11 PS > or = 2/squamous histology; 3 PS > or = 2/CNS involvement; 2 PS > or = 2/anticoagulation, 2 CNS metastasis/anticoagulation, 2 PS > or = 2/squamous histology/anticoagulation, 1 PS > or = 2/squamous histology/CNS metastasis). Of 34 eligible patients, only 6 (17.6%) enrolled in the trial. Based on the data reviewed, > 70% of patients who might otherwise have been eligible for standard advanced NSCLC trials were not candidates for ECOG 4599. Outcome with respect to this study must be interpreted in the context of eligibility restrictions.

    ABSTRACT: Irinotecan and cisplatin individually are active in non-small cell lung carcinoma (NSCLC). Each is synergistic with radiation. Dosages of 65 mg/m2 of irinotecan and 30 mg/m2 of cisplatin Q weekly times four every 6 weeks yielded a 36% response rate and median survival of 11.6 months in advanced NSCLC (Jagasia et al.; Clinical Cancer Research 7: 68, 2001). A weekly schedule for each agent (versus less frequent doses) limits toxicity and increases the opportunity for radiosensitization. We initiated a phase I study of weekly irinotecan and cisplatin during radical thoracic radiation (TRT). Cisplatin was fixed at 25 mg/m2 Q weekly times seven. Irinotecan was dosed initially at 30 mg/m2 per week for 7 weeks and was increased by 10 mg/m2 per week in three- to six-patient cohorts. TRT was administered in 34 single daily fractions to 63 Gy. Eligibility stipulated locally advanced NSCLC; Eastern Cooperative Oncology Group performance status 0 to 1; < or = 10% unintended weight loss; and adequate physiologic indices. Fifteen patients were accrued: nine were stage IIIB, five were stage IIIA, and one had isolated mediastinal node recurrence after prior surgery. Median age was 65 years (range, 47-77). Seven patients received irinotecan at a dose of 30 mg/m2 per week; (dose level 1). Seven other patients received irinotecan at a dose of 40 mg/m2 per week; (dose level 2). The one other patient received irinotecan in doses of 50 mg/m2 per week; (dose level 3). Neutropenic fever occurred in one patient each at dose levels 1 and 2. Grade 4 neutropenia occurred in three patients at each dose level. Transient grade 3 diarrhea occurred in one patient at dose level 1. Esophagitis of grade 3 or higher occurred in one patient each at dose levels 2 and 3. There was one late grade 3 pneumonitis at dose level 2. Delivered irinotecan dose intensity for dose level 1 was 27 mg/m2 per week; for dose level 2, it was 31.4 mg/m2 per week. Nine of 13 evaluable patients (69%) responded. At median potential follow-up of 5 years, 14 have progressed, and 11 have died. Projected median survival is 28 months; one patient who was treated for mediastinal node recurrence remains free from progression at 6 years. Weekly irinotecan and cisplatin combined with radical TRT (63 Gy) is active and fairly well tolerated in locally advanced NSCLC. In combination with fixed-dose cisplatin (25 mg/m2 per week), the maximum-tolerated dose of irinotecan is 30 mg/m2 per week.

    ABSTRACT: To evaluate the cost-effectiveness of adding hormone therapy to radiation for patients with locally advanced prostate cancer, using a Monte Carlo simulation of a Markov Model. Radiation Therapy Oncology Group (RTOG) protocol 86-10 randomized patients to receive radiation therapy (RT) alone or RT plus total androgen suppression (RTHormones) 2 months before and during RT for the treatment of locally advanced prostate cancer. A Markov model was designed with Data Pro (TreeAge Software, Williamstown, MA). The analysis took a payer's perspective. Transition probabilities from one state of health (i.e., with no disease progression or with hormone-responsive metastatic disease) to another were calculated from published rates pertaining to RTOG 86-10. Patients remained in one state of health for 1 year. Utility values for each health state and treatment were obtained from the literature. Distributions were sampled at random from the treatment utilities according to a second-order Monte Carlo simulation technique. The mean expected cost for the RT-only treatments was 29,240 dollars (range, 29,138-29,403 dollars). The mean effectiveness for the RT-only treatment was 5.48 quality-adjusted life years (QALYs) (range, 5.47-5.50). The mean expected cost for RTHormones was 31,286 dollars (range, 31,058-31,555 dollars). The mean effectiveness was 6.43 QALYs (range, 6.42-6.44). Incremental cost-effectiveness analysis showed RTHormones to be within the range of cost-effectiveness at 2,153 dollars/QALY. Cost-effectiveness acceptability curve analysis resulted in a >80% probability that RTHormones is cost-effective. Our analysis shows that adding hormonal treatment to RT improves health outcomes at a cost that is within the acceptable cost-effectiveness range.

    ABSTRACT: Previously, we have linked theoretically based cognitive and emotional variables to the ability of cancer patients to quit smoking. Purpose: In this study, we evaluated the impact of cognitive-behavioral therapy (CBT), which addressed these theoretically derived cognitive and emotional variables linked to tobacco use in this population, for promoting smoking cessation in a sample of cancer patients and assessed longitudinal predictors of smoking cessation. Cancer patients (N=109) were randomized to either the theoretically based CBT intervention or to a general health education (GHE) condition, and all patients received nicotine replacement therapy. Contrary to our expectation, no significant difference in 30-day point-prevalence abstinence between the CBT and GHE conditions was detected at either a 1-month (44.9 vs. 47.3%, respectively) or 3-month (43.2% vs. 39.2%, respectively) follow-up evaluation. Higher quit motivation and lower cons of quitting were related to smoking cessation. Implications for the implementation of smoking cessation behavioral treatments in the oncologic context are discussed, as are directions for future research in this area.

    ABSTRACT: Patients with local recurrences or new head and neck primary tumors in previously irradiated tissues have few options for salvage treatment. One option for select patients is to undergo reirradiation with concurrent chemotherapy. The purpose of this study is to report the initial clinical results of the Fox Chase phase I and II prospective reirradiation and chemotherapy studies. Between July 1996 and January 2002, 38 patients with locally recurrent unresectable squamous cell carcinoma of the head and neck were treated with concurrent chemotherapy and reirradiation on two prospective trials. All patients had received prior radiation therapy to the head and neck region (median dose, 64.2 Gy). Patients received cisplatin and paclitaxel along with hyperfractionated external beam radiation therapy to the site of recurrence. The median follow-up was 10 months. The median survival was 12.4 months, with actuarial rates of overall survival of 50% and 35% at 1 and 2 years, respectively. During follow-up, 63% of patients experienced local progression of disease, all in the irradiated field. Actuarial progression-free survival at 1 year was 33%, with a median time to progression of 7.3 months. Acute grade 3 to 4 toxicity included neutropenia, nausea, emesis, and mucositis. Hyperfractionated split-course reirradiation and concurrent cisplatin and paclitaxel chemotherapy demonstrates durable locoregional control in select patients, although late toxicity may occasionally be significant. Only sites of disease recurrence need to be covered in the reirradiation fields.

    ABSTRACT: Even though survival and quality of life are adversely affected by smoking among cancer patients, about one-third of cancer patients who smoked prior to their diagnosis continue to smoke. One barrier to the provision of smoking cessation treatments to cancer patients is the paucity of data on the characteristics of cancer patients who continue to smoke and a lack of data on correlates of quit motivation in this population. This descriptive study assessed demographic, medical, smoking history, and psychological characteristics of cancer patients in a smoking cessation program (N=111) and examined these characteristics as correlates of quit motivation. Methods used by patients to quit smoking were also queried. We found that: (1) most patients are Caucasian, married, diagnosed with head and neck (versus lung) cancer, highly addicted to nicotine, and in the contemplation or preparation stage of change; (2) most patients attempt to quit smoking without formal treatment, although 33-50% have used the transdermal nicotine patch, nicotine gum, or bupropion; (3) depressive symptoms, low quitting self-efficacy, low perceived risk, and low perceived benefits of quitting are prevalent among patients, but most patients do not endorse the perceived disadvantages of quitting or fatalistic beliefs; and (4) quit motivation is associated with higher quitting self-efficacy, risk perceptions, and perceived benefits of quitting, lower tobacco use and nicotine addiction, and shorter time since diagnosis. These findings can help guide the development of smoking cessation interventions for cancer patients.

    ABSTRACT: Background.Despite the availability of smoking interventions for cancer patients, many eligible patients decline enrollment into such programs. We examined reasons patients provide for declining smoking treatment and compared treatment decliners to enrollees.Methods.Eligible cancer patients (N = 231) were offered smoking cessation treatment. During recruitment, demographic, medical (eg, cancer stage), and smoking-related behavioral (eg, readiness to quit) data were collected, and decliners stated a reason for refusal. Patients who enrolled in the cessation program (N = 109) were compared with those who declined (N = 122) in terms of recruitment data, and reasons for declining were compiled.Results.Decliners were significantly more likely to: (1) have head and neck cancer (vs lung cancer); (2) exhibit fewer physical symptoms (eg, shortness of breath); (3) report a lower readiness to quit smoking; (4) indicate no intention to quit smoking; and (5) smoke fewer cigarettes. A preference to quit without professional assistance was the most common reason for declining treatment.Conclusions.Our findings highlight important differences between patients who enroll in a smoking cessation program and those who decline and underscore the need for motivational interventions to facilitate enrollment into smoking interventions for cancer patients. © 2004 Wiley Periodicals, Inc.

    ABSTRACT: Virtually all patients with advanced non-small-cell lung cancer (NSCLC) relapse. Docetaxel has an established, Food and Drug Administration-approved role as salvage therapy in previously treated, platinum-exposed patients. However, the response rate in phase III studies is < 15%, and median survival is only 6-8 months. Temozolomide, a novel triazene derivative with activity in melanoma and anaplastic astrocytoma, has demonstrated activity in C26 adenocarcinoma, Lewis lung cancer, and in phase I studies. A phase II trial was mounted using a unique schedule of oral temozolomide 75 mg/m2 daily for 6 weeks every 8-10 weeks, in patients with previously treated, advanced, incurable NSCLC. Eligibility stipulated an Eastern Cooperative Oncology Group performance status (PS) of 0-2, adequate end organ function, up to 1 prior chemotherapy for advanced (relapsed or metastatic) disease, and up to 1 prior regimen in the context of radiosensitization, adjuvant therapy, or induction. From March 2000 through January 2002, 47 patients (24 male, 23 female) were enrolled. The median age was 67 years. Sixteen patients had a PS of 2, 22 had a PS of 1, and 9 had a PS of 0. It was too early to evaluate 9 patients. Toxicity, with the exception of mild nausea and thrombocytopenia, was negligible. Three patients had a delayed recovery of platelets prompting discontinuation of treatment. Of the 38 evaluable patients, 1 patient had a complete response, 2 patients had a partial response, 12 had stable disease, and 19 had disease progression. Four patients were not evaluable. Six patients died within 30 days of taking temozolomide; 5 of these deaths were not related to treatment upon review by an independent data safety monitoring committee. Temozolomide, using a unique 6-week continuous schedule, has demonstrated activity in the salvage therapy of advanced NSCLC. Toxicity is modest, and accrual to this study continues.
