目的对2种液基薄层细胞学方法筛查宫颈癌和癌前病变的对比进行分析与评价,以期找到宫颈癌早期筛查质量好又经济的方案。方法2007年3～10月,对980例患者分别采用Hong Xiang细胞学检测系统(489例)和新柏氏薄层细胞学检测系统(TCT,491例)进行宫颈病变的早期筛查,对167例(HongXiang 82例,TCT 85例)细胞学阳性或临床可疑的患者行阴道镜下活组织检查。结果Hong Xiang检查的阳性率与TCT细胞学检查的阳性率比较差异无统计学意义(P>0.05);Hong Xiang细胞学检查在诊断宫颈低度病变、高度病变与宫颈癌的准确率上与TCT比较,差异无统计学意义(P>0.05)。结论Hong Xiang细胞学检测系统可以替代新柏氏薄层细胞学检测系统并降低耗材。     

Tisotumab vedotin in Japanese patients with recurrent/metastatic cervical cancer: Results from the innovaTV 206 study

New treatments, particularly second‐line options, are needed to improve outcomes for patients with recurrent/metastatic cervical cancer (r/mCC). Tisotumab vedotin (TV) is an antibody–drug conjugate directed to tissue factor, a transmembrane protein commonly expressed in cancer cells, to deliver cytotoxic monomethyl auristatin E. This single‐arm, open‐label phase 1/2 trial evaluated the consistency of safety and efficacy outcomes of TV in Japanese patients with r/mCC to bridge the current findings with those reported in previous trials in non‐Japanese patients in the United States and Europe. In part 1 (dose escalation; N = 6), patients with advanced solid tumors received TV 1.5 or 2.0 mg/kg once every 3 weeks to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). Part 2 (dose expansion; N = 17) evaluated the RP2D in r/mCC patients with 1–2 prior lines of therapy. In part 1, no dose‐limiting toxicities were observed, the MTD was not reached, and TV 2.0 mg/kg was established as the RP2D. In part 2, the most common treatment‐emergent adverse events were anemia (58.8%), nausea (58.8%), alopecia (47.1%), epistaxis (47.1%), and diarrhea (35.3%); adverse events of special interest were bleeding (76.5%), ocular events (35.3%), and peripheral neuropathy (17.6%), and were mostly grade 1/2. In part 2, confirmed objective response rate was 29.4%, median duration of response was 7.1 months, and median time to response was 1.2 months. In Japanese patients with r/mCC, TV demonstrated a manageable and tolerable safety, pharmacokinetics, and efficacy profile consistent with that observed in non‐Japanese patients.     

静止中立位状态及加载模拟头部重量后对髓核内压力影响的研究

目的:通过测试颈椎标本在静止中立位及模拟头部重量后的髓核内压力,从而探讨颈椎髓核内压力的变化规律。方法:利用生物力学材料实验机及微型压力传感器测试新鲜人体颈椎标本在静止中立位及加载100N压力时的髓核内压力。结果:静止中立位及加载100N压力时,C3～4和C4～5节段髓核内压力比较无显著性差异(P0.05),C5～6和C6～7节段髓核内压力比较无显著性差异(P0.05);C5～6,C6～7高于C3～4,C4～5髓核内压力(P0.05);加载100N后所有节段髓核内压力均升高具有显著性差异(P0.05)。结论:正常人体下颈段髓核内压力高于上颈段髓核内压力,并且随外在负荷的增加而压力增加。

Attitudes towards HPV testing: a qualitative study of beliefs among Indian,Pakistani, African-Caribbean and white British women in the UK

This study examined attitudes to human papillomavirus (HPV) testing among a purposively selected sample of women from four ethnic groups: white British, African Caribbean, Pakistani and Indian. The design was qualitative, using focus group discussion to elicit women's attitudes towards HPV testing in the context of cervical cancer prevention. The findings indicate that although some women welcomed the possible introduction of HPV testing, they were not fully aware of the sexually transmitted nature of cervical cancer and expressed anxiety, confusion and stigma about HPV as a sexually transmitted infection. The term 'wart virus', often used by medical professionals to describe high-risk HPV to women, appeared to exacerbate stigma and confusion. Testing positive for HPV raised concerns about women's sexual relationships in terms of trust, fidelity, blame and protection, particularly for women in long-term monogamous relationships. Participation in HPV testing also had the potential to communicate messages of distrust, infidelity and promiscuity to women's partners, family and community. Concern about the current lack of available information about HPV was clearly expressed and public education about HPV was seen as necessary for the whole community, not only women. The management of HPV within cervical screening raises important questions about informed participation. Our findings suggest that HPV testing has the potential to cause psychosocial harm to women and their partners and families.     

Hysterectomy for hematometra in a 15-year-old mentally handicapped girl with congenital cervicovaginal agenesis and concomitant ovarian adenoma

We report a case of hematometra and bilateral hematosalphinx in a 15-year-old mentally handicapped adolescent girl, complicated by vaginal agenesis over cervical atresia in the presence of an ovarian adenoma. The case was managed by abdominal hysterectomy and bilateral salphingectomy of the hematosalphinx, which had formed a tubo-ovarian mass. One ovary was preserved. This case also considers the management of the mentally handicapped patient unable to comprehend pain arising from cryptomenorrhea.     

Stage IIB carcinoma of the cervix that is associated with pelvic kidney: A therapeutic dilemma

Locally advanced cervical cancer with congenital pelvic kidney is reported uncommonly. A 50-year-old patient with stage IIB cervical cancer and pelvic kidney was treated with irradiation and concurrent chemotherapy. Follow-up evaluation for 2 years revealed normal renal function and no evidence of recurrent disease.     

Pap smear screening history of women with squamous cell carcinoma and adenocarcinoma of the cervix

BACKGROUND: Since the introduction of the Pap smear screening, the incidence of squamous cell carcinoma (SCC) has decreased significantly, but the incidence of adenocarcinoma (AC) relative to SCC has increased. AIM: To compare the Pap smear history of patients with AC and SCC of the cervix. METHODS: Patients for the study were identified from the database of Queensland Centre for Gynaecological Cancer. Patients with AC and SCC were matched for age at diagnosis and International Federation of Gynecology and Obstetrics stage. The final population included 188 matched pairs, being 376 patients in total. Data were collected upon the histological type of cancer, result of the most recent Pap smear, date and result of the Pap smear prior to the most recent Pap smear and symptoms. Chi-squared tests and Fisher's exact test were used to compare the two patient groups for several variables. RESULTS: Patients with AC had significantly more false-negative results on their most recent Pap smear (P<0.0001) than patients with SCC. The incidence of symptoms such as bleeding and/or vaginal discharge was comparable in patients with AC and SCC. The time between the most recent Pap smear and the diagnosis of cervical cancer was significantly shorter for patients with AC (P=0.01). CONCLUSIONS: Patients with AC had Pap smears more regularly than those with SCC, and their most recent Pap smear was significantly more likely to be normal. Thus, Pap smear prior to a diagnosis of AC is more likely than SCC false-negative and therefore not indicative of cervical cancer.
