Objective Explore the effect of case method on clinical teaching of Medical Oncology. Methods The case method was taken in the teaching of Clinical Oncology for trial group,and the traditional method teaching was taken for contrast group of our university. At the end of term, we made a questionnaire and statistics examination records. Results (1) It was conducive to good learning ability. Case method teaching in Clinical Oncology could cultivate student's ability to study independently. (2) Comparing examination records of the two groups, it also showed a significant difference ( <0.05) . Conclusion (1) Case method teaching has good teaching effect, and it can cultivate student's ability to study independently. (2) Application of case teaching method in Clinical Oncology received a very good teaching result, but the assessment system should be established and improved.

Objective To investigate the clinical characteristics of hodgkin's lymphoma (HL) patients . Method The clinical data of HL patients in our hospital from January 1, 2003 to December 31, 2012 were analyzed retrospectively. The contents of investigation included gender, age, pathological type, first symptom, the incidence locations, clinical stages, extranodal involvement locations, ECOG and treatments.Results A total of 143 cases of HL were included, the M/F ratio was 2.5:1 with a median age of 37 years (11~73years) . The most frequent subtypes of HL were mixed cellular (34.3%) and nodular sclerosis (28.0%) . The nodal lymphomas accounted for 97.2%, while the extranodal lymphomas occupied 2.1%. The nodal lymphomas with extranodal invasion accounted for 29.5%, and the common locations were spleen (14.4%), lung (5.8%) and bone (5.0%) . The most clinical stage of all patients was stage Ⅰ/Ⅱ (60.8%), The differences were no significant in gender, pathological type, first symptom, the incidence locations and the effective rate of the first-line treatment (P>0.05), while were statistically significant in B symptoms, ECOG and treatments betweenⅠ/Ⅱgroups andⅢ/Ⅳgroups (P<0.05) . Conclusions In this group,the incidence of HL patients were mainly found in middle-aged people, males were lager than females.The pathological type, first symptom and the incidence locations had no obvious effect on clinical stage. The clinical stage had no obvious influence on the effective rate of the first-line treatment.

This study analyzed the distribution of high-risk population, the compliance and detected lesions of colorectal cancer screening from the Cancer Screening Program in urban areas of Kunming,Yunnan Province from 2014 to 2017. A total of 127 960 residents were included,of which 14 791 (11.70%) cases were diagnosed with high risk of colorectal cancer by the National Cancer Center High Risk Population Assessment System. A total of 3 484 cases completed colonoscopy clinical screening and the rate of participation was 23.55%. The screening results showed that 592 positive cases were detected, and the positive rate was 17.17%. The detection rates of polyps,adenomas,advanced adenomas,precancerous lesions and colorectal cancer were 16.27%,13.12%,7.18%,7.63% and 0.26%, with 567, 457, 250, 266 and 9 cases, respectively.
