Tumor 2012;32(8):605-608
Objective: To analyze the trends of female breast cancer incidence and mortality in Beijing, Shanghai, Linzhou and Qidong in China between 1988 and 2007. Methods: The data of female breast cancer incidence and mortality and the data of corresponding population during 1988-2007 were collected from four eligible cancer registries which could provide complete sets of historical data. The pooled analysis and time-trend analysis of the data were performed. Results: During 1988-2007, the APCs (annual percent changes) of age-standardized incidence rates (by China's population in 1982) of female breast cancer in Beijing, Shanghai, Linzhou and Qidong were 2.49%, 2.55%, 7.04% and 4.16%, respectively. Although the average annual growth of APC of age-standardized mortality was 4.10% in Linzhou, there were no significant changes in Beijing, Shanghai and Qidong. Conclusion: During 1988-2007, the breast cancer incidence and mortality of the urban women in Beijing and Shanghai were significantly higher than those of the rural women in Linzhou and Qidong. The incidence rate of female breast cancer in these four areas showed an obvious rising trend, and this increase was more significant in rural areas. The mortality rate of female breast cancer in Linzhou also showed a rising trend, but the mortality rates in the other three areas remained steady. Copyright © 2012 by TUMOR.

Objective: To describe the incidence and mortality of female breast cancer in China during 2003-2007. Methods: The incidence and mortality data of female breast cancer and the corresponding population data from 32 eligible cancer registries in China during 2003-2007 were collected and analyzed. Results: The combined crude incidence rate of female breast cancer during 2003-2007 was 41.64 per 100 000, which was the highest among female cancer incidence rates. The combined crude mortality rate of female breast cancer was 9.63 per 100 000, which was ranked as the sixth among the mortality rates of all female cancers. The incidence rate was 3.04 times higher and the mortality rate was 1.92 times higher in urban areas than those in rural areas. Compared to the incidence and mortality rates of 184 regions provided from GLABOCAN 2008 database, the female breast cancer incidence in China was ranked as the one hundred and tenth, and the mortality was ranked as the one hundred and seventy-second. Conclusion: Breast cancer has been becoming one of the most common cancers among Chinese women. The incidence and mortality rates of female breast cancer in urban areas are significantly higher than those in rural areas, although the overall incidence and mortality rates of breast cancer in Chinese women are still at a medium or low level in the world. © 2012 by Tumor.
5.Analysis of 12R-lipoxygenase gene mutations in three families with self-improving collodion ichthyosis
Chinese Journal of Dermatology 2021;54(5):397-401
Objective:To analyze gene mutations in 3 families with self-improving collodion ichthyosis.Methods:Clinical data were collected from 3 patients with self-improving collodion ichthyosis. DNA was extracted from the peripheral blood of patients and their parents, and high-throughput sequencing was performed in the patients by using a multi-gene panel targeting congenital ichthyosis. After identification of causative gene loci, Sanger sequencing was performed to bidirectionally verify the mutations in the patients and their parents.Results:All the 3 patients presented with a collodion-like membrane at birth, which was shed within 2-4 weeks after birth, and then they gradually showed similar features of mild ichthyosis, including dry skin, tiny scales at local sites, flexural involvement, mild sweating, heat intolerance, cheek flushing, mild palmoplantar keratosis or palmar hyperlinearity. Compound heterozygous mutations were identified in the ALOX12B gene of the 3 patients, including a paternal mutation c.406_408delGAG and a maternal mutation c.77T>C in case 1, a paternal mutation c.1013C>T and a maternal mutation c.1286C>G in case 2, a paternal mutation c.1232T>C and a maternal mutation c.1440C>A in case 3. Function prediction analysis showed that 4 missense mutations c.77T>C, c.1286C>G, c.1013C>T, c.1232T>C and 1 deletion mutation c.406_408delGAG may exert pathogenic effect, and 1 nonsense mutation c.1440C>A led to the generation of a termination codon encoding a truncated protein p.Tyr480Ter, which may affect the protein function and cause disease. None of the 6 mutation sites had been reported in the past.Conclusion:Compound heterozygous pathogenic mutations were identified in the ALOX12B gene of the 3 patients with self-improving collodion ichthyosis, which were inherited from their parents.
