Does core needle breast biopsy accurately reflect breast pathology?

BACKGROUND: Core needle breast biopsy (CB) has replaced excisional biopsy as the initial diagnostic biopsy procedure for many suspicious breast lesions; however, CB remains a sampling procedure. The purpose of this study was to determine the degree of agreement between histology obtained at CB and that obtained at a subsequent excisional procedure (EP). We hypothesized a high degree of agreement. METHODS: Data were collected prospectively for 3035 CBs performed by breast radiologists using either ultrasound or stereotactic guidance between January 1995 and July 2002, 1410 (46%) of which had a subsequent EP within 1 year. Histologic categories were defined as invasive breast cancer, duct carcinoma in-situ, atypia/lobular carcinoma in-situ, and benign. The principal histology (PH) from CB and EP was identified and compared. RESULTS: Overall, there was moderate agreement (kappa=0.669) between CB and EP histology. Complete agreement occurred in 1168 (83%) procedures. For the remaining 242, the PH was identified only at CB for 78 (5%) procedures, and only after EP for 164 (12%) procedures. CONCLUSIONS: Although the majority (83%) of CB and EP demonstrated exact histologic agreement, CB was diagnostic for 1246 (88%) procedures.     

Does screen-detected breast cancer have better survival than symptomatic breast cancer?

OBJECTIVES: Evidence obtained from several randomized control trials suggest that mortality from breast cancer could be reduced by mammographic screening. However, a recent meta-analysis questioned the general acceptance that screening for breast cancer is beneficial. The purpose of the study was to analyze prospectively collected data from our unit and produce overall and comparative 5-year survival rates for screen-detected and symptomatic breast cancer. METHODS: Prospectively collected data on all patients diagnosed with invasive breast cancer between January 1993 and December 1994 (24 months), and monitored until the end of 1999, were collated and analyzed. Five-year survival was estimated and broken down by age at diagnosis, tumour size, grade and nodal status. The overall 5-year survival for women with screen-detected cancers was compared with that for women with symptomatically presenting cancers. RESULTS: Between January 1993 and December 1994, 308 patients with invasive breast cancer were referred to the unit (162 via the breast screening programme and 146 presenting symptomatically). The overall 5-year survival was 85.5% (confidence interval [CI], 80.8-89.1). Small tumour size, low grade and negative nodal status were associated with higher survival rates. Five-year survival of the screen-detected cancer patients (91.7%; CI, 85.8-95.2) was higher than that of patients presenting symptomatically (78.6%; CI, 70.6-84.6; p < 0.001). CONCLUSIONS: These findings suggest that patients with screen-detected breast cancer may have better survival compared to those with symptomatically detected breast cancer. The results support the argument in favour of a beneficial impact of breast screening programmes on patients' survival.     

Exploring breast surgeons’ reasons for women not undergoing immediate breast reconstruction

IntroductionFactors influencing breast reconstruction rates in Canada are complex and multi-factorial, ranging from patient-related to systemic considerations. For plastic surgeons, rates of immediate breast reconstruction (IBR) hinge on referral patterns from general surgeons performing breast cancer surgery and informed discussions with patients about their goals and risk tolerance. We seek to understand the reasons Alberta patients are not receiving IBR as reported by general surgeons.MethodsThe Synoptec™ database is a synoptic operative report designed by Cancer Surgery Alberta™ and utilized by 95% of Alberta breast cancer surgeons. Within this report are mandatory questions regarding if a patient is receiving IBR and, if not, why. A retrospective review of this database was performed for all patients undergoing surgical treatment of breast cancer over two years. All statistical comparisons were made using chi-squared test for categorical variables with a p-value of 0.05 considered significant.ResultsOf 6253 patients undergoing breast cancer surgery, 2649 underwent mastectomy and 615 mastectomy patients received IBR. The most commonly reported reasons patients did not undergo IBR were patient preference (55%), high likelihood of postoperative radiation therapy (20%), and high risk due to patient co-morbidities (12%). Resource limitations (2%) and a lack of an IBR discussion (3%) was rarely cited as reasons for no IBR.ConclusionsThere are many reconstructive options following mastectomy in breast cancer survivors. This study provides a unique look into general surgeon reported reasons patients are not receiving IBR and demonstrates the need for further probing into the thought-process behind these reported reasons from both a surgeon and patient perspective.     

Are risk factors for breast cancer similar in women with inflammatory breast cancer and in those with non-inflammatory breast cancer?

PURPOSE: The aim of the study was to compare reproductive factors in patients with inflammatory breast cancer (IBC), and with non-inflammatory breast cancer (non-IBC). The study was performed in two centers: one French including 49 IBC patients and 140 non-IBC and another Tunisian including 97 IBC and 139 non-IBC. Unconditional logistic regression was used for the analyses. PATIENTS AND METHODS: The French IBC patients had a lower educational level, a higher body mass index and a longer cumulative duration of breast-feeding, and they included a greater proportion of non-European women, than the non-IBC patients. In the multivariate analysis, only breast-feeding duration remained associated with the IBC status (P=10(-3)). These results could not be verified in the Tunisian series, because the duration of breast-feeding was unavailable in this center. RESULTS: This study suggests that the etiology of IBC might be different of that of non-IBC.     

Interval breast cancer: is it a different type of breast cancer?

We have compared tumour type, tumour size, tumour grade and axillary lymph node status in three groups of women, 230 interval breast cancers (IC) in the West Sussex Breast Screening programme and 625 screen detected (SD) cancers and 916 symptomatic (S) cancers treated at Worthing Hospital between July 1989 to April 1996. Our true interval cancer detection rates were 5.28, 11.28 and 15.3 per 10,000 screened women for the 1st, 2nd and 3rd year after screening. The proportionate incidences of true interval cancer were 29%, 61% and 82% for the 1st, 2nd and 3rd year, similar to others' programmes in UK. In our programme a large proportion (42%) of IC and more than half of the true IC presented in the 3rd year after screening. Out of 230 interval cancers, 40% (90) were unclassifiable, the remaining 60% (140) were classified as: True interval cancers (T) 54% (76), False Negative Subtle (FNS) 12% (16), Occult (O) 12% (17), and 22% (31) as False Negative (FN). Analysis of interval cancers according to their classification did not demonstrate any significant difference with respect to tumour size (chi2 5.59, df 4, P=0.22), tumour grade (chi2 5.29, df 4, P=0.25) and axillary node status (chi2 3.16, df 4, P=0.53) thus establishing interval cancers as a single group. Invasive ductal carcinoma of no specific type was the main tumour type in all three groups. Analysis of variance (ANOVA) showed significant differences in size between the groups (df 2, F=71.36, p<0.0001). Symptomatic cancers were 1.19 times the size of IC while SD were 0.83 times the size of IC. The difference in groups in terms of tumour grade was significant (Kruskal-Wallis test chi2 33.31, df 2, P<0.0001). The incidence of grade 2 tumours was similar in the three groups while a third of the IC and S were grade 3 tumours. Comparison of axillary node status showed a significant difference between the three groups (chi2 26.59, df 2, P<0.0001). When means and 75th percentiles were compared IC had the greatest number of positive nodes while SD had the smallest number of positive nodes. Interval cancers are the middle spectrum between symptomatic and screen detected breast cancers and represent small cancers (<10 mm) not detected at the time of screening and de novo cancers developing in the screening interval. The need for improving the sensitivity of current screening methods and identifying newer methods of breast cancer detection is highlighted by our study.     

Objective analyses of mastalgia in breast clinics: Is breast pain questionaire a useful tool in a busy breast clinic?

The aim of this study was to investigate the feasibility of use of breast pain questionnaire (BPQ), a short, focussed and robustly designed tool to assess severity of mastalgia and its impact on quality of life, in a busy breast clinic. Seventy-four consecutive women completed BPQ prior to their consultation with a Breast Surgeon. Based on the BPQ score, mastalgia was graded as mild (score 0-100) in 26%, moderate (score 101-200) in 59% and severe (score >200) in 15% of patients. In 93% of patients breast pain lasted for more than 5 days and visual analogue score (VAS) was more than 3.5 in 82% of patients. The breast pain was described as mild (12%) discomforting (55%), distressing (22%) excruciating (3%) or horrible (8%). All results are presented as median (interquartile ranges). Out of maximum possible 100, overall pain rating was 17(9-31), percent sensory component was 21(12-33) and percent affective component was 0(0-17). The percent VAS was 60(40-80), percent pain index was 40(40-60) and quality of life score (maximum possible 60) was 20(0-40). Of maximum possible score of 360, total breast pain was 137(99-180). In conclusion BPQ can be used routinely in a busy breast clinic as a quick, user-friendly and reliable tool to assess the degree and severity of breast pain in order to provide an organised approach to the management of mastalgia.     

Results of breast conserving surgery in clinical stage I–II breast carcinoma

Background  

The role of breast conserving surgery with radiotherapy is well established and has become a widely used procedure in breast cancer. Patient selection, a multidisciplinary approach, and expert surgical technique are important factors to avoid locoregional recurrence. The aim of this study was to analyse the outcomes of patients treated with breast conserving surgery in stage I–II breast cancer.     

Can breast surgeons read mammograms of symptomatic patients in the one-stop breast clinic?

AIM: To establish how accurate surgeons were when compared to the radiologists in interpreting symptomatic mammograms in one-stop clinics. METHODS: The surgeons were asked to write their opinion on the mammograms which was compared with the radiologists' report. 144 patients were involved in the study and the data were analysed by McNemara's test for paired categorical data. RESULTS AND CONCLUSIONS: Surgeons were accurate in interpreting most of the mammographic findings. However, they underestimated the presence of benign calcification which was statistically significant. Surgeons can, therefore, be involved in double reading of mammograms in symptomatic breast disease patients and improve the sensitivity which has been the case in double reading by radiologists in the breast screening programme.     

What is achieved by mammographic surveillance after breast conservation treatment for breast cancer?

BACKGROUND: Hereditary nonpolyposis colorectal cancer (HNPCC) accounts for approximately 2% to 5% of all colorectal cancers. Rectal cancer in HNPCC is not well characterized. METHODS: A retrospective medical record review of HNPCC patients with colorectal cancer diagnosis from December 1948 to December 1999 was performed in an attempt to elucidate the natural history of rectal cancer in HNPCC. Group A consisted of patients diagnosed with rectal cancer as the index colorectal cancer. Group B consisted of patients diagnosed with rectal cancer as a metachronous colorectal cancer. RESULTS: Twenty-five of 104 patients developed rectal cancer in our HNPCC registry. There were 18 patients in group A with a median age at diagnosis of rectal cancer of 48 years (range 24 to 79) and 7 patients in group B diagnosed at a median age of 58 years (range 45 to 68). Three of 18 patients (17%) in group A developed metachronous colon cancers at a median of 203 months (range 27 to 373) from the index rectal cancer. Rectal cancer in group B was diagnosed at a median 245 months (range 51 to 564) from the index colorectal cancer diagnosis. CONCLUSIONS: Rectal cancer in HNPCC is not uncommon. The presentation of rectal carcinoma should not obviate the evaluation for HNPCC in suspected cases.     

Benign breast disorders in nonwestern populations: Part II—Benign breast disorders in India

Experience with benign breast disorders has been analyzed in 3 nonwestern populations: Hong Kong, India, and Northern Nigeria. Similarities to and differences from Western experience are found, but of great interest are notable differences between these populations which, as yet, lack explanation. All show fibroadenosis and fibroadenoma as common conditions, but the frequency with which phyllodes tumor is diagnosed varies between different centers in India as well as between different racial groups. Tuberculosis is another interesting example—wide differences in the frequency of breast infection are found although tuberculosis itself is common in all 3 countries. The value of prospective studies was shown when mastalgia was studied in this way in India. Often considered a Western affliction, these authors have been able to study 112 cases of mastalgia and found it to be twice as common as cancer as a presentation. These differing experiences between populations have been little explored and must hold promise for unravelling some of the enigmas of benign breast disorders in all countries.

Resumen Se analizó la experiencia con enfermedades mamarias benignas en 3 poblaciones no occidentales: Hong Kong, India, y Nigeria Septentrional. Se hallaron similitudes y también diferencias con relación a la experiencia occidental; pero de mucho interés son algunas notorias diferencias entre estas poblaciones para las cuales no existe explicación. Todas exhibieron adenosis y fibroadenoma como entidades comunes, pero la frecuencia en el diagnóstico de tumores filodes varía en diferentes centros en la India, así como en los diferentes grupos raciales. La tuberculosis constituye otro ejemplo de interés; se encuentran grandes variaciones en la incidencia de infección mamaria, aunque la tuberculosis es común en las 3 naciones. La utilidad de los estudios prospectivos fue demostrada cuando se estudió la mastalgia en esta forma en la India. Frecuentemente considerada como una entidad nosológica occidental, los autores pudieron estudiar 112 casos de mastalgia y encontraron que es 2 veces más común que el cáncer como forma de presentación. Estas diferencias entre poblaciones han sido escasamente investigadas y son promisorias en cuanto a clarificar algunos de los enigmas de las enfermedades mamarias benignas prevalentes en todos los países.

Résumé L'expérience de 3 équipes de pays non occidentaux (Hong Kong, Inde, et Niger du Nord) avec des maladies bénignes du sein a été analysée. On a trouvé peu de similitudes, mais aussi des différences par rapport aux pays occidentaux. C'est surtout pour ces dernières, qui sont les plus intéressantes, qu'on manque d'explications. Dans les 3 pays, on voit fréquemment des fibroadénomes et des patientes avec une fibroadénose, mais la fréquence des tumeurs phyllodes varie parmi les différents centres de l'Inde, ainsi que parmi les groupes de races différentes dans ce pays. La tuberculose est un autre exemple. De grandes variations de l'incidence des infections du sein sont retrouvées alors que la tuberculose est fréquente dans les 3 pays. La valeur des études prospectives a été démontrée par une étude sur les mastalgies en Inde. Les auteurs ont étudié 112 cas de mastalgie, souvent considérée comme une maladie occidentale. Ils ont trouvé qu'elle était deux fois plus fréquente que le cancer. Ces expériences entre populations différntes n'ont pas été explorées en totalité et pourraient éclaircir un jour quelques unes des énigmes qui entourent les maladies bénignes du sein dans tous les pays du monde.

What about the other breast? A review of a series of bilateral breast carcinomas

The BreastScreen Queensland Brisbane Southside BreastScreen Service reports on a study of 10 cases of bilateral breast carcinomas from a total cancer population of 217 cases. All cases were patients of screening examinations that were recalled for a suspicious lesion in one breast. Two cases were mammographically suspicious of bilateral tumours. In eight cases, tumours were ultrasonically visible in both breasts and in two further cases, the suspicion of bilateral malignancy was raised by the presence of bilateral microcalcification. It is not the purpose of this paper to provide a statistical analysis of the occurrence of bilateral breast cancer. This is a radiological paper from a breast screening service reporting on findings that conventional wisdom may find unusual. The incidence of bilateral breast malignancy in the study was found to be somewhat higher than expected. These cases have been diagnosed by the utilization of a particularly high standard of ultrasound and mammography, performed and interpreted by diagnosticians possessing an elevated level of suspicion of the possible presence of a second primary lesion. It is therefore proposed that an increased rate of diagnosis of bilateral tumours is possible with an evolution of assessment protocols, combined with quality ultrasound and mammography.     

Pregnancy-associated breast cancers: Do they differ from other breast cancers in young women?

The impact of pregnancy in the physiopathology of pregnancy-associated breast cancer (PABC) is still unclear. We compared the characteristics of PABCs and breast cancers not associated with pregnancy (non-PABCs) in terms of their loco-regional invasion and histological phenotype. We conducted a retrospective chart review on women less than 43 years of age treated for breast cancer from January 1, 2004 to December 31, 2010. We compared age at diagnosis, loco-regional invasion and histological data. We recorded 282 breast cancers in 276 patients. Forty-one tumors (14.5%) were PABCs. PABC patients were significantly younger than non-PABC patients. Compared with the non-PABCs, PABCs were twice more frequent advanced tumors (T3-4) and have twice more frequent HER2 over-expression and hormone negative status. The more aggressive histological profile observed in the PABCs, especially in post-partum tumors and women older than 35 years of age, seems to be a direct consequence of the association with pregnancy.     

What do breast surgeons do?

Background

There are an increasing number of fellowship-trained breast surgeons and surgical oncologists who dedicate their clinical practice exclusively to breast disease. However, there are little published data regarding characteristics of a breast surgical practice.

Methods

All patient visits at a university-based breast surgery practice were reviewed for calendar years 2006 and 2007.

Results

There were 10,381 patient visits, of which 2,334 (22%) represented new patients. Of these, 11% were referred with a diagnosis of cancer. Out of the remainder, 29% had a needle biopsy (8% by the surgeon and 21% by radiology), 29% underwent surgery, and 13% were ultimately diagnosed with cancer. After completion of initial therapy, 6 months or 1 year follow-up was recommended for 59% of the patients.

Conclusions

The specialty of breast surgery is unique in its nonoperative volume and extensive duration of follow-up. Strategies need to be designed to make this process more time-efficient for the surgeon.
