Objective To evaluate operation and chemotherapy in patients with stage Ⅱ testicular seminoma. Methods Forty-four patients with stage Ⅱ testicular seminoma collected from February 1993 to August 2007 were treated with cisplatin-based chemotherapy with repeated course. The retroperitoneal lymph node in ten patients were resected and two patients operated after chemotherapy. Results Resected tissue in eight patients after chemotherapy were necrosis and fibrosis, two patients were viable cancer. All patients were followed up for two to eight years. Five year survival rate was stage ⅡA 100 %(11/11), stage ⅡB 91.67 % (22124), stage Ⅱc 77.78 %(7/9). Conclusion For raising survival rate and controlling disease development of the patients who suffered from stage Ⅱ testieular seminoma,the repeated courses of chemotherapy should be given as early as possible.

Objective To observe the safety and efficacy of FOLFOX4 regiment in elderly versus young patients with advanced colorectal cancer. Methods There were 61 patients enrolled in this study, with 28 elderly patients aged 70 years and over, 33 young patients aged less than 70 years.They suffered from advanced/recurrent colorectal cancer and received FOLFOX4 regiment (Oxaliplatin +CF+5-FU). Every 14 days were as a cycle, and the therapeutic safety and efficacy were evaluated after three cycles. Adverse events and response to treatment were compared between the elderly and young patients. Results The main adverse effects were myelosuppression, gastrointestinal disturbance and neurotoxicity. The incidence rate of diarrhea was significantly higher in elderly patients than in young patients, but the most of diarrhea were at grade Ⅰ - Ⅱ. The incidence rates of leucocyte decrease and neutrophil decrease were higher in elderly patients than in young patients (92. 8% vs. 78. 8%, 39.3% vs. 36.3%), but there were no statistically significant differences between them. The incidence rate of neurotoxicity was 46.5% in elderly patients and 36.4% in young patients (P＞0. 05). The recent efficacy rate was 25%, disease control rate was 71.4% and median time-to-progression (TTP) was 6 months in elderly patients and 24.2%, 84.8% and 7 months in young patients (all P＞0.05). Conclusions FOLFOX4 regiment is well-tolerated and effective in both young and elderly patients.

Purpose:To validate further the importance of r adiotherapy following breast-conserving surgery in early breast cancer. Methods:From 1994.12 to 2001.12,237patients with early stage breast can cer were treated Of these patients,eighty-three received breast-conserving surgery followed by radiotherapy,and one hundred and fifty-four received modified radical mastectom y.All patients with breast-conserving surgery underwent postoperative radiother apy.The range of radiation dose depends on the size,location of tumor,and involv ement of axillaty nodes.Tangential chest wall fields delivered 5000cGy with 8MV -X ray beam in 5 weeks .An additional 1500cGy was delivered in 8 days to tumor bed with electron beam.Among the patients with modified radical mastectomy.only 3 received postoperative radiotherapy.Results:In both the breast-conserving surgery group and modified radical mastectomy gro up,one patient recurred regionally,and one died respectively .In the modified ra dical mastectomy group,there were no regional lymph nodes recurrence,but two of them had distant metastasis.The 5year survival of the two groups were 96.49%and 98.61%,respectively.The breasts are soft and resilient in the breast-conserving surgery group,and breast shape whole after surgery.Conclusions :Breast-conserving surgery plus postoperative radiotherapy in early breast can cer can obtain treatment results similar to modified radical mastectomy,with goo d cosmetic

Objective:To investigate the differences in the expression levels of miR-196a-5p and miR-105-5p in serum of patients with benign and malignant pulmonary nodules and their diagnostic value of malignant pulmonary nodules.Methods:The expression levels of miRNAs in cancer tissues of lung adenocarcinoma and lung squamous cell carcinoma and paracancerous tissues in The Cancer Genome Atlas (TCGA) database were analyzed, and the miRNAs with significantly different expression levels in cancer tissues and paracancerous tissues were selected as target miRNAs. A total of 72 patients with pulmonary nodules admitted to Weifang People′s Hospital of Shandong Province from June 2019 to July 2020 were selected. The expression levels of target miRNAs in serum of patients with pulmonary nodules were detected by qRT-PCR. Receiver operating characteristic (ROC) curve was used to compare the diagnostic value of target miRNAs with tumor markers Cyfra21-1, NSE and CEA in malignant pulmonary nodules.Results:After screening, the target miRNAs were identified as miR-196a-5p and miR-105-5p. Twenty-six patients in the benign pulmonary nodules group and 46 patients in the malignant pulmonary nodules group were included. The levels of serum miR-196a-5p [ M ( P25, P75)] in the benign and malignant nodules group were 0.63 (0.09, 2.15) and 1.93(0.93, 4.97) respectively, and the levels of miR-105-5p in the two groups were 2.03 (0.54, 7.95) and 10.65 (5.94, 18.39) respectively. Compared with the benign pulmonary nodules group, the levels of serum miR-196a-5p and miR-105-5p in the malignant pulmonary nodules group were increased, and there were statistically significant differences ( Z=-3.083, P=0.002; Z=-4.092, P<0.001). The levels of serum Cyfra21-1 in the benign and malignant pulmonary nodules group were 2.48 (1.84, 3.78) and 2.20 (1.47, 3.32) μg/L respectively, the levels of serum NSE in the two groups were 15.58 (12.45, 18.95) and 14.43 (12.07, 17.87) μg/L respectively, and the levels of serum CEA in the two groups were 1.16 (0.55, 2.11) and 1.17 (0.61, 1.68) μg/L respectively. There were no significant differences in serum Cyfra21-1, NSE and CEA between the benign and malignant pulmonary nodules group ( Z=-1.161, P=0.246; Z=-0.305, P=0.761; Z=-0.271, P=0.786). The area under the curve (AUC) of the combination of miR-196a-5p and miR-105-5p for the diagnosis of malignant pulmonary nodules was 0.762 (sensitivity 89.1%, specificity 61.5%), which was higher than the value of the combination of Cyfra21-1, NSE and CEA for the diagnosis of malignant pulmonary nodules (AUC=0.591, sensitivity 58.7%, specificity 64.5%). Conclusion:The combination of serum miR-196a-5p and miR-105-5p can assist in the diagnosis of malignant pulmonary nodules and has higher diagnostic value.
