New insights into the aetiology of scrotal cancer, a nationwide case-control study in the Netherlands.

BACKGROUND: Although scrotal cancer is traditionally regarded as an occupational disease, there is increasing evidence that factors which are involved in cutaneous and genital carcinogenesis might play a role in the carcinogenesis of scrotal cancer. OBJECTIVE: This exploratory study aimed to detect exposures that might have an aetiological relation with scrotal cancer. METHODS: A nationwide population-based case-control study was conducted in the Netherlands. The patients were identified through the Netherlands cancer registry. Controls were recruited among acquaintances of the cancer registry registrars. The participants completed a questionnaire that included questions on occupational exposures, naked sunbathing, use of sunbeds, skin diseases and their treatments, treatments for cancer and sexually transmitted diseases. Age-adjusted odds-ratios (ORs) were calculated. RESULTS: Forty-seven scrotal cancer patients and 125 controls completed the questionnaire. The patients were categorized according to histology of the scrotal tumours. Having had a skin disease (OR = 6.3, 95% CI = 1.8-22), especially psoriasis (OR = 8.7), increased the risk of squamous cell carcinomas (SCC) of the scrotum. A previous cancer diagnosis may affect the risk of scrotal basal cell carcinomas (BCC; OR = 4.9, 95% CI = 0.9-27.3). Furthermore, an association between the number of sexual partners and the occurrence of scrotal sarcoma was found. CONCLUSION: Scrotal SCCs may be related with skin diseases or skin disease treatments. Having had cancer may be a risk factor for a BCC of the scrotum. Scrotal sarcomas seem to be correlated with the number of sexual partners. This study suggests that scrotal cancer has characteristics of both cutaneous and genital carcinogenesis.

Enhancing the quality of care for patients with breast cancer: seven years of experience with a Dutch auditing system.

BACKGROUND: Hospitals in the Midwestern part of the Netherlands carried out a clinical audit to monitor the quality of breast cancer care during the years 2002-2008. Compliance with the National Guideline was investigated together with improvement in quality over time. METHODS: Patients with a malignancy of the breast (including ductal carcinoma in situ) participated in this study. Nine quality indicators were evaluated over the years. In 2004 and 2005 the hospitals also carried out an intervention project aimed at improvement of the efficiency of both the diagnostic process and the surgical treatment. RESULTS: At the end of the project all nine indicators showed significant improvement compared to the start of the project. Discussion of treatment strategy in a multidisciplinary breast cancer team took place more often before surgery (83% versus 56%) as well as after surgery (98% versus 70%). The National Guideline for maximum waiting times was met more often for the outpatient clinic (74% versus 61%), time to diagnosis (92% versus 82%), and surgical treatment (52% versus 34%). More sentinel node procedures were performed successfully (92% versus 69%), and for more patients more than 10 lymph nodes were evaluated in case of axillary lymph node dissection (85% versus 58%). More patients had definitive surgical treatment consisting of one surgical intervention (87% versus 75%), and left the hospital within 7 days after hospital admission (98% versus 66%). CONCLUSION: The clinical audit contributed to improvement of the quality of breast cancer care in the Midwestern part of the Netherlands between 2002 and 2008.
