indication of radiological margins. This study assessed the use of this tech- nology in reducing re-excision rates. Methods: 200 cases of WLE for palpable tumours were randomly sampled from the hospital data bank: 100 cases from 2005e06 (pre-Faxi- tron) and 100 from 2011e12 (Faxitron). Data were gathered on age, tumour size, grade, closest excision margin, dimensions excised, intra-/ post-operative re-excision of margins and cavity biopsies. Data were ana- lysed using SPSS Statistics 20 Results: Conclusion: Intra-operative Faxitron use for palpable breast cancers reduces the need for secondary re-excision of margins, improving cost effectiveness and allowing earlier post-operative radiotherapy http://dx.doi.org/10.1016/j.ejso.2013.07.191 Axillary management in operable breast cancers Medhat Alaker, William Maxwell Withybush Hospital, Wales Deanery, UK Introduction: Axillary assessment is mandatory in staging Operable Breast Cancers. The procedure of choice is Sentinel Node Biopsy (SNB) which, if positive, will require the patient to have a second procedure for Secondary Axillary Node Clearance (ANC), or to have axillary radiotherapy.

The aim of this study is to assess node positivity rates after SNB, Secondary ANC, and Pri- mary ANC. Methods: Notes of all patients admitted for axillary management over a 2 year period have been assessed retrospectively. Results: A total of 367 axillae have been assessed. 259 had Sentinel Node Biopsies, of which 66 were positive for metastasis (25.4%). Of the 65 who proceeded to Secondary ANC, 23 yielded further positive nodes (35.4%). 36 patients had a Primary ANC, (N1 and patient/sur- geon’s choice), which yielded a node positivity rate of 85.7%. Node pos- itivity rates for Screen detected Breast cancers vs. Symptomatic Breast cancers were 13.8% and 46% respectively, yielding a Relative Risk of 3.33. Conclusion: Primary ANC is practical and feasible; with a high node positivity rate of 85.7%. Around 65% of patients who had Secondary ANC after having a positive SNB are disease free, which raises the issue regarding the feasibility of subjecting the patient to another operation rather than receiving radiotherapy of the axilla. http://dx.doi.org/10.1016/j.ejso.2013.07.192 2 week rapid access colorectal clinic audit Veronika Pronisceva, Tariro Gandiya, Mohamed M.

Axillary management in operable breast cancers

Medhat Alaker, William Maxwell

Withybush Hospital, Wales Deanery, UK

Introduction: Axillary assessment is mandatory in staging Operable

Breast Cancers. The procedure of choice is Sentinel Node Biopsy (SNB)

which, if positive, will require the patient to have a second procedure

for Secondary Axillary Node Clearance (ANC), or to have axillary

radiotherapy.

Pre-operative diagnosis of axillary metastasis, by ultrasound-guided

Fine Needle Aspiration or Core biopsy, can avoid the patient going through

another operation, and proceed directly to a Primary ANC. The aim of this

study is to assess node positivity rates after SNB, Secondary ANC, and Pri-

mary ANC.

Methods: Notes of all patients admitted for axillary management over

a 2 year period have been assessed retrospectively.

Results: A total of 367 axillae have been assessed. 259 had Sentinel

Node Biopsies, of which 66 were positive for metastasis (25.4%). Of

the 65 who proceeded to Secondary ANC, 23 yielded further positive

nodes (35.4%). 36 patients had a Primary ANC, (N1 and patient/sur-

geon’s choice), which yielded a node positivity rate of 85.7%. Node pos-

itivity rates for Screen detected Breast cancers vs. Symptomatic Breast

cancers were 13.8% and 46% respectively, yielding a Relative Risk

of 3.33.

Conclusion: Primary ANC is practical and feasible; with a high node

positivity rate of 85.7%. Around 65% of patients who had Secondary ANC

after having a positive SNB are disease free, which raises the issue

regarding the feasibility of subjecting the patient to another operation

rather than receiving radiotherapy of the axilla.

Introduction: Parosteal osteosarcomas are low-grade variants of oste-

osarcoma and rarely occur in the head and neck region. As noted in liter-

ature, their typical localisation is the distal femur. Even though clinical and

radiographic features are informative, definitive diagnosis requires histopa-

thology, supported by genetic studies.

Methods: Case report and literature review.

Results: We report a case of a calvarial parosteal osteosarcoma that

required wide local excision and acrylic cranioplasty. She presented with

a gradually increasing left-sided scalp swelling over about 7 years, and a

2-month history of progressive headache. Examination revealed an obese

lady with a hard left fronto-parietal scalp swelling of approximately 8 x

5 x 2 cm3. Imaging studies demonstrated a large calcified lesion anterior

to the outer table of the left frontal lobe and extending antero-laterally,

with no demonstrable skull table invasion. The patient’s management plan

was determined in consultation with the Specialist Sarcoma Service. So

far, there has been no radiological evidence of a recurrence 23 months after

surgery. Literature review and case reports were identified by a compre-

hensive search of MEDLINE.

Conclusions: This case report illustrates the importance of a multidisci-

plinary approach in treating rare tumours.With optimal treatment, the tumour

has a good prognosis; however incomplete excision can result in local recur-

rence. Metastatic spread may even occur if the tumour has dedifferentiated.

Chemotherapy and radiotherapy are not advocated in the treatment of

parosteal osteosarcoma. Extended follow-up is essential, as metastasis can

present even more than 10 years after presentation.

Do young women (£40 years) with breast cancer have more aggressive

invasive cancer compared with older women?

John Mathew, Carla Hope, Yasmin Wahedna

Royal Derby Hospital, Derby, UK

Aim: The aim was to assess the predictive and prognostic factors in

young women (� 40 years) with breast cancer and compare with older

age group with symptomatic breast cancer. We also analysed the long

term outcome in young women with symptomatic breast cancer.

Method: Retrospective review of breast cancer patients (� 40 years)

undergoing breast surgery between January 2006 to February 2011 (group

1). We compared the pathology data of young patients with same number

of consecutive symptomatic breast cancer patients > 40 years who were

operated between January 2012 to August 2012 (group 2). Data was ana-

lysed using SPSS 19 and p value of <0.05 was considered significant.

Results: There were 94 patients in each group. Median age was 36

years and 65 years in group 1 and 2 respectively. Median tumour size

was 22 mm and 23 mm in group 1 and 2 respectively. Significantly

more patients in group 1 had grade 3 cancers compared to group 2 (60%

versus 45%; P¼0.04). Significantly more patients in group 1 had triple

negative disease (25% versus 10%; P¼0.002). There were no significant

differences between the groups with regard to lymph node status.

After a median follow-up of 41 months (6e83), eight patients (9%)

developed local recurrence and 12 patients (13%) had distant metastases

in group 1. Eighty eight percent were alive at the end of follow up.

Conclusion: Young women with breast cancer are associated with

some adverse prognostic factors (more patients with grade 3 and triple

negative disease) compared with older group.

mrEMVI status should be used in addition to pEMVI for treatment

decision making in rectal cancer to prevent under-reporting of

extramural venous invasion

Introduction: Extramural venous invasion (EMVI) is increasingly rec-

ognised as an important prognostic factor in rectal cancer. Traditional his-

topathological methods have been shown to be variable and lead to under-

reporting. MRI can accurately identify EMVI (mrEMVI), pre-operatively.

This study aimed to show that mrEMVI can be used as an adjunct to pa-

thology-detected EMVI (pEMVI).

Methods: Retrospective analysis of prospectively collected data was

conducted comparing MRI-detected and pathology-detected EMVI

following neoadjuvant chemotherapy in patients that had presented with

rectal cancer and evidence of mrEMVI on baseline staging. Correlation

was tested using Kappa agreement and comparison of 3-year DFS made

with Mantel-Cox log rank test. Multivariate analysis was performed using

a binary logistic regression model for disease recurrence.

Results: 211 patients were included. There was agreement between

MRI and pathology for detection of EMVI in 43.4% of cases (Kappa

0.29). There was no difference in 3-year DFS or recurrence rates between

the patients with mrEMVI or pEMVI (Mantel-Cox p>0.05) or between

mrEMVI-negative and pEMVI-negative tumours (p>0.05); however there

was significant difference in 3-year DFS and recurrence rates between

pEMVI positive and negative patients (p<0.05). mrEMVI and pEMVI pos-

itive status were the only significant radiological or pathological factors

associated with disease recurrence following CRT on multivariate analysis

with odds ratios of 1.97 and 2.39, respectively.

Conclusion: Pathologists may be under-reporting EMVI in rectal can-

cer. Whilst the importance of pathological identification must not be lost, it

may be prudent to consider features on MRI in addition to help guide ac-

curate staging.

Male breast cancer: Our 10 year experience

Natasha Jiwa, Hem Rai, Steven Goh

Breast Unit, Peterborough City Hospital, Peterborough, Cambridgeshire,

UK

Introduction: Male breast cancer (MBC) is rare and accounts for less

than 1% of breast cancers. Treatment guidelines for MBC are usually

extrapolated from data derived from female patients. We evaluated our

practice in this retrospective study.

Methods: All MBC treated in our unit between January 2003 and

December 2012 were included. Cancer registry, case-notes, radiological

and histopathological reports were used for data collection. Patient demo-

graphics, tumour characteristics, treatment and survival data were analysed.

Results: Seventeen patients were diagnosed with MBC during the10--

year period. One patient had simultaneous bilateral cancers. Median age at

diagnosis was 69 [41e77] years. Median follow-up was 27 [3e69]

months. The common presenting complaints were painless breast lump,

nipple changes and bleeding. There were 15 cases of invasive carcinoma,

2 DCIS and 1 case of encapsulated intracystic solid carcinoma.

Thirteen patients underwent mastectomies with curative intent. Four

patients had axillary nodal metastases, and 4 patients had axillary and

distant metastases. Three patients underwent neo-adjuvant chemotherapy

but passed away before surgery. Chemotherapy was given to 5 patients,

and 7 patients underwent radiotherapy. All invasive cancers were oestrogen

receptor positive, and 3 were HER2 receptor positive. One patient devel-

oped local chest wall recurrence. Twelve patients remained disease-free

but all 4 patients with Stage IV MBC have succumbed to their diseases.

One patient has died of medical morbidities.

Conclusions:MBC patients were older at diagnosis when compared with

female patients. Therapy regimes derived from treating female breast cancer

are effective, and survival ofMBC is comparablewithmatched female cohorts.
