yet others at 90% {97,2147}. For pragmatic reasons, a 90% purity re q u i re m e n t o ffers a practical solution. Tumours exhibiting between 50 and 90% tubular growth pattern with other types should be regarded as mixed type of carcinoma (see Mixed type carcinomas). Differential diagnosis Sclerosing adenosis (SA) can be distinguished from tubular carcinoma by its overall lobular arc h i t e c t u re and the marked compression and distortion of the glandular structures. Myoepithelial cells are always present in sclerosing adenosis and can be highlighted by immunostaining for actin. Similarly, a fully retained basement membrane can be shown by immunohistological staining for collagen IV and laminin in tubules of SA. Microglandular adenosis (MA) can be more difficult to differentiate because of the rather haphazard arrangement of the tubules, and lack of myoepithelial cells in the tubules. However, the tubules of MA are more rounded and regular and often contain colloid-like secretory material, at least focally, compared to the often angulated tubules of tubular carc i n o m a . Furthermore a ring of basement membrane is present around tubules of MA. Complex sclerosing lesions/radial scars have a typical arc h i t e c t u re with central f i b rosis and elastosis containing a few small, often distorted, tubular structures in which myoepithelial cells can be demonstrated. The surrounding glandular struct u res show varying degrees of dilatation and ductal epithelial hyperplasia. Immunophenotype Tubular carcinoma is nearly always e s t rogen and pro g e s t e rone re c e p t o r positive, has a low growth fraction, and is ERBB2 and EGFR negative {691, 1 3 7 9 , 2 1 6 6 } . Genetics Tubular carcinomas of the breast have a low frequency of genetic alterations when compared to other types of bre a s t c a rcinoma. Using LOH and CGH techniques, alterations have been found most frequently at chromosomes 16q (loss), 1q (gain), 8p (loss), 3p FHIT gene locus, and 11q ATM gene locus {1754,1779,2476, 3046}. Of part i c u l a r i n t e rest is the observation that other sites of chromosomal alteration pre v i- ously found at high levels in other types Fig. 1.25 Invasive cribriform carcinoma. The haphazard distribution of irregularly shaped and angulated invasive areas is in contrast with the rounded configuration of the ducts with cribriform DCIS on the left side of the field. of breast cancer are not seen, which implies that tubular carcinoma of the b reast is genetically distinct. Prognosis and predictive factors Pure tubular carcinoma has an excellent long term prognosis {409,410,552,771, 1829,2081,2224} which in some series is similar to age matched women without breast cancer {691}. Recurrence following mastectomy or breast conservation treatment is rare and localized tubular carcinomas are considered to be ideal candidates for breast conservation techniques. Following breast conservation, the risk of local recurrence is so low that some centres consider adjuvant radiotherapy unnecessary. Axillary node metastases occur infrequently, and when observed rarely involve more than one low axillary lymph node. There is little adverse effect of node positivity in tubular carcinoma {691,1471} and the use of systemic adjuvant therapy and axillary node dissection are considered unnecessary by some groups {691,2166}. Invasive cribriform carcinoma Definition An invasive carcinoma with an excellent prognosis that grows in a cribriform pattern similar to that seen in intraductal cribriform carcinoma; a minor (90%) of an invasive cribriform patt e rn. The tumour is arranged as invasive islands, often angulated, in which well defined spaces are formed by a rches of cells (a sieve-like or cribrif o rm pattern). Apical snouts are a re g- ular feature. The tumour cells are small and show a low or moderate degree of nuclear pleomorphism. Mitoses are r a re. A prominent, reactive appearing, f i b roblastic stroma is present in many ICC. Intraductal carcinoma, generally of the cribriform type, is observed in as many as 80% of cases {2148}. Axillary lymph node metastases occur in 14.3% {2148}, the cribriform pattern being retained at these sites. Lesions showing a predominantly cribriform arrange- Invasive breast cancer 27
