Conservative treatment of breast ductal carcinoma in situ: results of an Italian multi-institutional retrospective study.

Background: The incidence of ductal carcinoma in situ (DCIS) has increased markedly in recent decades. In the past, mastectomy was the primary treatment for patients with DCIS, but as with invasive cancer, breast-conserving surgery followed by radiation therapy (RT) has become the standard approach. We present the final results of a multi-institutional retrospective study of an Italian Radiation Oncology Group for the study of conservative treatment of DCIS, characterized by a very long period of accrual, from February 1985 to March 2000, and a median follow-up longer than 11 years.

[Post-radiation pelvic disease and ureteral stenosis: physiopathology and evolution in the patient treated for cervical carcinoma. Review of the literature and experience of the Radium Institute].

Ureteral stenosis secondary to radiation-induced fibrosis is a well-known, late complication of radiation treatment in patients with carcinoma of the uterine cervix. This paper focuses on epidemiological data, physiopathology and treatment modalities reviewed from Internet-published literature. Experience from a single institution (Institute of Radiotherapy of Brescia) is reported.
