Elevated levels of serum ferritin of 500 ng/mL or more as well as the use of chemotherapy regimens besides CHOP-like or RCHOP, a high-intermediate/high risk IPI, and a high level of beta2-microglobulin in NHL may be an important marker for predicting poor survival outcomes.
Erdheim-Chester disease is a rare non-Langerhans-cell histiocytosis with bone and organ involvement. A 76-year-old man presented with low back pain and a history of visits for exertional dyspnea. We diagnosed him with anemia of chronic disease, cytopenia related to chronic illness, chronic renal failure due to hypertension, and hypothyroidism. However, we could not determine a definite cause or explanation for the cytopenia. Multiple osteosclerotic axial skeleton lesions and axillary lymph node enlargement were detected by computed tomography. Bone marrow biopsy revealed histiocytic infiltration, which was CD68-positive and CD1a-negative. This report describes an unusual presentation of Erdheim-Chester disease involving the bone marrow, axial skeleton, and lymph nodes.
A phase I study was carried out to determine the optimal dose and administration schedule for combined UFT plus gemcitabine therapy in patients with non-small cell lung cancer. Twenty-four patients (including 11 patients previously treated with cisplatin as the key drug) received oral UFT 400 mg m 72 on days 1 to 14 with intravenous infusions of gemcitabine (800 mg gemcitabine on days 8 and 15. Eight of the 24 patients achieved partial response. The combination chemotherapy UFT and gemcitabine was well tolerated and may benefit patients with advanced non-small cell lung cancer. A multicentre phase II study using a 3-weekly regimen is in progress.
In this study of locally advanced or metastatic ALK+ NSCLC patients in Korea, roughly one-third did not receive an ALK inhibitor. Among patients who discontinued crizotinib, over half received no further antineoplastic therapy and OS was poor, particularly among patients without second-generation ALK inhibitor use. These findings suggest a need for greater access to effective treatments following crizotinib discontinuation for ALK+ NSCLC patients in Korea.
Objective: Multimodal treatments that include preoperative platinum-based chemotherapy are fundamental to the treatment of advanced non-small cell lung cancer (NSCLC). This study aimed to investigate the predictive value of DNA repair protein expression in surgically resected NSCLCs in terms of prognosis and responses to platinum-containing chemotherapy. Methods: This retrospective study included 136 patients with NSCLC who were treated with preoperative platinum-based chemotherapy, followed by curative lung resection. ATM, RAD51, LKB1, H2AX, and SIRT1 expression levels were analyzed in resected tumor specimens via immunostaining and were used to classify patients and compare survival and responses to chemotherapy. Results: SIRT1 expression correlated significantly with improved responses to platinum-based chemotherapy (odds ratio, 2.28; p = 0.024), progression-free survival (hazard ratio [HR], 0.74; p = 0.036), overall survival (HR, 0.63; p = 0.006), and tumor-bearing survival (HR, 0.62; p = 0.014). After adjusting for clinical variables, the HR of SIRT1 expression remained significant for overall survival (HR, 0.59; p = 0.039) but not for progression-free survival (HR, 0.74; p = 0.183). No prognostic stratification was observed for the other 4 markers. Conclusion: Patients with SIRT1-expressing NSCLC had superior responses to chemotherapy and longer survival durations than those with SIRT1-negative cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
