Adriamycin has been found effective in metastatic osteogenic sarcoma. To determine its efficacy osteosarcoma without detectable metastases, 21 patients were given adjuvant adriamycin therapy two weeks (median) after surgical amputation of the primary lesion. Six courses (30 mg per square meter daily for three days, repeated every four to six weeks) administered. Nineteen survived from more than one 32 months (median, nine months) operation. Five relapsed (two with local and pulmonary...

A prospective randomized trial was conducted comparing the clinical response of 78 previously untreated patients with advanced metastatic breast cancer to a combination cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) or adriamycin, (CAF). Sixty-two percent receiving CMF responded treatment compared an 82% rate for CAF. Although within acceptable limits, hematologic GI toxicity greater There no significant difference in duration two regimens. Therefore, therapeutic between therapies...

Streptozotocin was administered to 106 patients with advanced malignancies. Therapeutic responses were observed in Hodgkin's disease, 7/16, lymphocytic lymphoma, 3/11, Burkitt's 1/12, and acute leukemia, 1/5. Two of 7 islet cell carcinoma, 1 insulin-secreting serotonin-secreting, responded, but 8 malignant carcinoid tumors originating from the ileum failed demonstrate a reduction either urinary 5-hydroxyindole acetic acid or tumor mass.

Objective Participation, an indicator of screening programme acceptance and effectiveness, varies widely in clinical trials population-based colorectal cancer (CRC) programmes. We aimed to assess whether CRC participation rates can be compared across organized guaiac fecal occult blood test (G-FOBT)/fecal immunochemical (FIT)-based programmes, what factors influence these rates. Methods Programme representatives from countries participating the International Cancer Screening Network were...

Importance Population-based colorectal cancer (CRC) screening programs are implemented worldwide, but there difficulties evaluating their effectiveness. The magnitude of routine CRC effectiveness regarding cancer-specific mortality is unclear. Objective To evaluate associated with early vs late or no invitation for using fecal occult blood testing.

Twenty-four patients with non-Hodgkin's lymphoma and CNS involvement are presented. There were 7 cases diffuse histiocytic (HL), 9 poorly differentiated lymphocytic (PDLL-D), of whom 6 in leukemic conversion, 5 nodular (PDLL-N), 3 undifferentiated (UL). complications noted only Stage IV lymphoma; the prognosis was generally poor. Histiocytic associated widespread parenchymatous infiltration, whereas PDLL usually leptomeningeal seeding. The clinical course neuropathologic findings discussed.

Summary Small non-coding RNAs have emerged as possible biomarkers for various diseases including autoimmune diseases. A number of studies demonstrated that the expression specific microRNAs (miRNAs) is dysregulated in rheumatoid arthritis (RA). So far, all on miRNAs RA patients been performed using either microarray or reverse transcription–quantitative polymerase chain reaction (RT–qPCR) analyses. Compared to RT–qPCR and analyses, next-generation sequencing (NGS) allows genome-wide analysis...
