Chemotherapy-naive Patients (chemotherapy-naive + patient)
Selected AbstractsRole of novel targeted agents in the treatment of metastatic colorectal cancerASIA-PACIFIC JOURNAL OF CLINICAL ONCOLOGY, Issue 1 2007Dragan DAMIANOVICH Abstract Modern chemotherapy regimens, combining bolus or infused schedules of 5-fluorouracil (5-FU) with irinotecan or oxaliplatin, have significantly improved the treatment outcomes of patients with metastatic colorectal cancer (CRC). The addition of novel targeted agents to chemotherapy has the potential to increase the median survival of patients with metastatic CRC beyond 2 years. Bevacizumab, a monoclonal antibody (mAb) to vascular endothelial growth factor, has an established role in first-line treatment in combination with either 5-FU/leucovorin or irinotecan/5-FU/leucovorin regimens, while cetuximab, a mAb to epidermal growth factor receptor, in combination with irinotecan is more suitable for the treatment of refractory metastatic CRC. The use of bevacizumab in later stages of the disease and cetuximab in chemotherapy-naive patients as well as concurrent treatment with both agents is still under investigation. The landmark studies leading to the approval of these agents in the treatment of metastatic CRC as well as associated toxicity profiles and detailed treatment recommendations are discussed in this review. [source] Phase 2 trial of docetaxel and gefitinib in the first-line treatment of patients with advanced nonsmall-cell lung cancer (NSCLC) who are 70 years of age or older,CANCER, Issue 9 2008George R. Simon MD Abstract BACKGROUND This is a phase 2 study of chemotherapy-naive patients, 70 years of age or older, with nonsmall-cell lung cancer (NSCLC) who were treated with docetaxel and gefitinib. The primary endpoint was response rate (RR). Secondary endpoints were overall survival (OS) and progression-free survival (PFS). METHODS Eligible patients were treated with docetaxel 75 mg/m2 every 3 weeks and gefitinib 250 mg orally, daily. Docetaxel and gefitinib were given for 2 cycles beyond maximal response. Gefitinib was continued until disease progression. Comorbidities and activities of daily living were assessed (IADL). RESULTS Forty-four patients initiated therapy between March 2003 and May 2005. Seventeen patients (40%; 95% confidence interval [CI], 26%,57%) had a partial response and 48% had stable disease. The median PFS was 6.9 months (95% CI, 3.95,7.8 months). Median survival time was 9.6 months (95% CI, 4.6,16.3 months). On univariate analyses, sex, Eastern Cooperative Oncology Group Performance Status (ECOG PS), and Charlson comorbidities index (CCI) score were predictors of improved survival. On multivariate analyses female sex was a statistically significant predictor of survival. The median survivals were 22.8 months in women and 4.8 months in men. This regimen was well tolerated, with the most common adverse events being hyperglycemia, fatigue, and lymphopenia. CONCLUSIONS Docetaxel combined with gefitinib is active and well tolerated in patients with advanced NSCLC who are 70 years of age and older. This paradigm of treatment merits further investigation as a first-line treatment strategy. Female sex-specific confirmatory clinical trials with this regimen may be warranted.

[source] Prospective assessment of emotional distress, cognitive function, and quality of life in patients with cancer treated with chemotherapyCANCER, Issue 2 2004Gregoris Iconomou Ph.D. Abstract BACKGROUND The current study sought to delineate prospectively the rates and clinical course of emotional distress, cognitive impairment, and quality of life (QOL) in chemotherapy-naive patients with cancer and to consider the determinants of global QOL. METHODS Patients who consented to participate were administered the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire, the Mini-Mental State Examination (MMSE), and the Hospital Anxiety and Depression Scale before and at the end of treatment (EOT). RESULTS Of the 102 patients initially assessed, 80 (78.4%) completed the study. Most aspects of QOL did not change considerably over time. At EOT, patients reported only significant increases in fatigue and significant decreases in sleep disturbance. Although no significant changes emerged in the rates of anxiety or depression throughout chemotherapy, nearly one-third of the patients experienced severe emotional distress at both points in time. In addition, the authors observed neither significant alteration in the cognitive performance over time nor reliable associations between scores on the MMSE and subjective cognitive function, emotional distress, or QOL. Finally, depression proved to be the leading predictor of global QOL at baseline and at EOT. CONCLUSIONS The results indicated that a significant proportion of Greek patients with cancer experienced intense anxiety and depression throughout chemotherapy and confirmed the importance of depression as a strong predictor of global QOL. Routine screening of emotional distress across all phases of cancer is mandatory because it will contribute to the identification of patients who are in need of pharmaceutical and/or psychologic intervention.

[source] Bodyweight change during the first 5 days of chemotherapy as an indicator of cisplatin renal toxicityCANCER SCIENCE, Issue 9 2007Ikuo Sekine To determine whether bodyweight (BW) loss, daily urine volume (UV) or furosemide use are associated with cisplatin nephrotoxicity, performance status, serum chemistries before treatment, average daily UV, maximum BW loss and use of furosemide on days 1,5 of chemotherapy were evaluated retrospectively in chemotherapy-naive patients with thoracic malignancies who had received 80 mg/m2 cisplatin. Associations between these parameters and the worst serum creatinine levels (group 1, grade 0,1; and group 2, grade 2,3) during the first cycle were evaluated. Of the 417 patients (327 men and 90 women; median age, 59 years), 390 were categorized into group 1 and 27 were categorized into group 2. More women and older patients were observed in group 2 than in group 1 (11.1 vs 5.2%, P = 0.044, and 65 vs 59 years, P = 0.041, respectively). The median average daily UV was 3902 mL in group 1 and 3600 mL in group 2 (P = 0.021). A maximum BW loss ,2.1 kg was noted in 4.4% of patients in group 1 and 18.5% of patients in group 2 (P = 0.006). Furosemide was used in 206 (49.4%) patients. The median total dose of furosemide in groups 1 and 2 were 0 mg and 26 mg, respectively (P = 0.024). A multivariate analysis showed that a maximum BW loss ,2.1 kg and the total furosemide dose were significantly associated with group category. In conclusion, BW loss and total furosemide dose were associated with cisplatin nephrotoxicity. (Cancer Sci 2007; 98: 1408,1422) [source] | ||||||||||
