入选标准

  • - Written informed consent according to ICH/GCP, and national/local regulations
  • - Women >= 45 years old, any menopausal status
  • - Unilateral DCIS of any size
  • - American Society of Anesthesiologists (ASA) score 1 -2 and 3, only if able
  • to undergo surgery and yearly mammography (see Appendix E)
  • - Lesions of type 'calcifications only', detected by population-based or
  • opportunistic screening mammography
  • - Within twelve weeks of detection at least six 12 G biopsies (or the
  • equivalent of six 12 G needles) need to be taken from the area of the
  • calcification. This implies at least 7 cc volume irrespective of supplier, or
  • at least three 8G, four 9G, five 10G or five 11G biopsy needles need to be
  • taken to meet LORD*s eligibility criteria. Whatever needle size is applied, it
  • is essential to confirm that the biopsies contain representative calcifications
  • via biopsy radiography, microscopy, or both.
  • - In case of an extended lesion (> 5 cm): biopsies were taken from the center
  • and the periphery of the lesion, or from two peripheral parts of the lesion
  • - In case of multiple lesions with calcifications biopsies have been taken from
  • two, but not more, groups of calcifications
  • - Estrogen receptor >=80% positive and HER2 negative: 0 or 1+ or 2+ with
  • negative ISH), analysed centrally by pathology at NKI-AVL
  • - Marker placement at biopsy site (s) in the breast . Note: if patient prefers
  • surgery, marker placement is not mandatory.
  • - FFPE tissue blocks from the biopsy and, if applicable, from the resection
  • specimen, available for translational research purposes. If no FFPE tissue
  • blocks can be submitted, 10 unstained slides of 4-5 µm thickness from the
  • lesion(s) are acceptable
  • - Good correlation between pathological and radiological findings i.e. both
  • findings confirm low-risk DCIS and no suspicion high- grade DCIS or invasive
  • breast cancer
  • - The interval between histologic diagnosis of low-risk DCIS on biopsy and
  • randomization is <= 12 weeks

排除标准

  • -Estrogen receptor negative: <80% or HER2 positive: 3+, or 2+ with positive ISH
  • - Presence of either mass, increased focal density or architectural distortion
  • around the calcifications on mammography (suspicious for invasive disease)
  • - Presence of Paget*s disease, invasive breast cancer, or pleomorphic LCIS;
  • Lobular neoplasia, referring to atypical lobular hyperplasia (ALH) and/or
  • classic Lobular Carcinoma In Situ according to the WHO Classification of
  • Tumours of the Breast, is no reason to exclude
  • - Symptomatic DCIS e.g. DCIS detected by palpation or bloody nipple discharge
  • - Synchronous invasive carcinoma in the contralateral breast
  • - Prior history of invasive breast cancer or DCIS, prior surgery because of
  • benign breast lesion (s) is allowed
  • - Prior history of other cancer except carcinoma in situ of the cervix or basal
  • carcinoma of the skin
  • - Serious disease that precludes definitive surgical treatment (e.g
  • cardiovascular/ pulmonary/ renal disease)
  • - Individual with a family member with a known gene mutation associated with
  • increased risk of breast cancer, unless study participant is a proven
  • non-carrier of mutation
  • - Any psychological, familial, sociological or geographical condition
  • potentially hampering compliance with the study protocol and follow-up
  • schedule; those conditions should be discussed with the patient before
  • registration in the trial
  • - Pregnancy or breast-feeding. Contraceptive measures during the trial are
  • mandatory for those patients that will participate in standard treatment arm
  • and adequate counselling should be provided by the treating physician. The
  • duration of contraception will be specified by the treating physician according
  • to patient and treatment characteristics, standard clinical practice and
  • national regulations
