Article: [Incidence of Chemotherapy-Induced Nausea and Vomiting in Patients Receiving Carboplatin-Including Chemotherapy.]
[show abstract] [hide abstract]
ABSTRACT: The present study was designed to evaluate the incidence ofchemotherapy -induced nausea and vomiting(CINV)in patients receiving carboplatin. Chemo-naÏve patients with thoracic and gynecological malignancy, who were intended to be given carboplatin-including chemotherapy without aprepitant as antiemesis, were enrolled. CINV was assessed using a visual analog scale for a week after the final chemotherapy. Thirty-one patients were evaluated, and 6.5% and 48.4% of them developed vomiting and nausea after chemotherapy, respectively. Nausea in the delayed phase tended to be increased compared with that in the acute phase. The higher incidence of CINV was significantly correlated with younger ages(odds ratio= 0.355, 95% CI: 0.132-0.951, p=0.039). Our results indicate that further intensive antiemetic prophylaxis, such as using aprepitant or palonosetron, should be considered in patients receiving carboplatin.Gan to kagaku ryoho.

Article: Clinical outcomes in elderly patients administered gefitinib as first-line treatment in epidermal growth factor receptor-mutated non-small-cell lung cancer: retrospective analysis in a Nagano Lung Cancer Research Group Study.
[show abstract] [hide abstract]
ABSTRACT: The clinical efficacy and outcomes of gefitinib therapy as a first-line treatment for elderly patients with non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations were analyzed retrospectively. We analyzed chemotherapy-naïve NSCLC patients aged 75 years or older who had EGFR mutations (exon 19 deletion mutation or L858R), who were initially treated with gefitinib (250 mg) once daily in Nagano Prefecture. A total of 55 patients (16 men, 39 women) with a median age of 81.1 years (range; 75-94 years) treated between April 2007 and July 2012 were analyzed. The overall response rate and disease control rate were 72.7 % (95 % confidence interval (CI); 59.5-82.9 %) and 92.7 % (95 % CI; 82.0-97.6 %), respectively. Median progression-free survival and overall survival from the start of gefitinib treatment were 13.8 months (95 % CI; 9.9-18.8 months) and 29.1 months (95 % CI; 22.4 months-not reached), respectively. Two-year survival rate was 59.5 % (95 % CI; 41.0-78.0 %). Major grade 3 toxicities were skin rash (1.8 %) and increased levels of aspartate aminotransferase or alanine aminotransferase (7.3 %). First-line treatment with gefitinib for elderly EGFR-mutated NSCLC patients was effective and well tolerated. The results suggest that first-line gefitinib should be considered as a preferable standard treatment in elderly patients with advanced NSCLC harboring EGFR mutations.Medical Oncology 03/2013; 30(1):450. · 2.14 Impact Factor -
Article: Primary malignant sarcomatoid mesothelioma in the pericardium.
[show abstract] [hide abstract]
ABSTRACT: Primary malignant pericardial mesothelioma is an exceptionally rare tumor, and making an antemortem diagnosis of this disease is notoriously difficult. We herein report the case of a 61-year-old woman with pericardial mesothelioma who presented with shortness of breath and peripheral edema of the lower limbs. Chest computed tomography (CT) showed an anterior mass and thickened pericardium with multiple pericardial nodules. A biopsy of the mediastinal mass was performed using right thoracotomy, and the histological findings indicated a sarcomatoid tumor. The patient was treated with chemotherapy; however, she but died three months after diagnosis. An autopsy confirmed a final diagnosis of sarcomatoid type primary malignant pericardial mesothelioma following extensive immunohistopathological examinations.Internal Medicine 01/2013; 52(2):249-53. · 0.94 Impact Factor -
Article: Surgical outcomes in patients with small cell lung cancer: comparative analysis of computed tomograpy-detected patients with others.
[show abstract] [hide abstract]
ABSTRACT: It is shown that low-dose computed tomography (CT) screening is useful for a reduction in lung-cancer-specific mortality in heavy smokers. However, the information about effectiveness according to the histological types of lung cancer has not been adequately investigated especially small cell lung cancer (SCLC). The present study was performed to see the clinical benefit of CT screening in patients with SCLC following thoracotomy. We retrospectively reviewed the outcome in patients with early stage SCLC who initially underwent thoracotomy. The clinical stages and actuarial survival were estimated according to the three means of detection of SCLC: chest CT, radiographic screen, and symptomatically prompted cases. Sixty-nine patients (men/women, 63/6; mean age, 70 years) with SCLC underwent thoracotomy between 1991 and 2010 including chest CT (n = 13), radiographic screening (n = 39), and symptomatically prompted cases (n = 17). Pathological staging information included stage IA (n = 25), IB (n = 8), IIA (n = 13), IIB (n = 5), IIIA (n = 11), and IIIB (n = 7). Median survival time was 30.0 (95% confidence interval (CI): 22.0 to 57.0) months, with overall survival at 5 years of 34.3% (95% CI, 23.47 to 47.3). Nine patients (69%) with stage I were detected by CT which was significantly higher than those in other detection arms. However, there were no significant differences in the survival between CT and other detection arms. CT examination may be useful for detection in early stage SCLC potentially suitable for surgery, but the contribution to better clinical outcome in patients with SCLC remains unclear.World Journal of Surgical Oncology 01/2013; 11:61. · 1.12 Impact Factor -
Article: Phase I/II study of S-1 combined with biweekly irinotecan chemotherapy in previously treated advanced non-small cell lung cancer.
[show abstract] [hide abstract]
ABSTRACT: PURPOSE: This phase I/II study was designed to evaluate a combination of irinotecan and S-1 a new regimen for salvage chemotherapy in patients with advanced or metastatic non-small cell lung cancer (NSCLC). METHODS: The study group comprised patients with advanced or metastatic NSCLC who had previously received at least one platinum-containing chemotherapy. Patients received irinotecan on days 1, 15 and oral S-1 (40 mg/m(2) twice daily as a fixed dose) on day 1 to 14 of a 28-day cycle. RESULTS: In the phase I part, irinotecan was given in escalating doses of 70 (Level 1), 80 (Level 2), and 90 mg/m(2) (Level 3). Three of the 5 patients given Level 3 had dose-limiting toxicity, and Level 2 (80 mg/m(2) of irinotecan) was designated as the recommended dose. In phase II, 38 patients received a median of 7.4 cycles of irinotecan at the recommended dose. The overall response rate was 15.8 % (90 % confidence interval (CI): 6.1-25.5 %), and the median progression-free and overall survival times were 4.5 months (95 % CI: 3.5-5.0) and 15.0 months (95 % CI: 9.5-20.6) months, respectively. Toxicity was generally mild. Grade 3 or higher toxicity included neutropenia in 17.9 % of the patients, thrombocytopenia in 5.1 % and nausea in 7.7 %. CONCLUSION: Combination chemotherapy with S-1 and irinotecan was considered an effective salvage regimen in patients with advanced or metastatic NSCLC.Cancer Chemotherapy and Pharmacology 09/2012; · 2.83 Impact Factor
