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

Secondary re-excision of margins fell from 35% to 17% (p[0.004). In-
traoperative re-excision of margins increased from 10% to 31%
(p<0.001) during Faxitron use, associated with reduced excision
volumes.
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

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: The 62 day target for colorectal cancer pathway initi-
ated a need for novel strategies and improvement in cancer service deliv-
ery. Usually, suspected cancer patients were reviewed in routine follow-up
clinics.
Aim: To see whether a dedicated 2 week wait rapid access clinic
improved waiting times for investigations and was able to deliver service
requirements.
Methods: Retrospective data collection using endosoft, PACS system,
patient notes.
Standard: NICE-CG27 referral guidelines for suspected cancer.
Audit: May 2009 e July 2009, 147 patients. Data showed evidence of
poor performance in time management for some cancer patients.
Implementation:
� Dedicated rapid access clinic with 2 week referrals
� Created endoscopy slots with dedicated times and dates
� Forward radiology planning
Re-audit: July 2012 e October 2012, 120 patients.
Results:
Outcome:
� No significant reduction in time between GP ref to OPC
� No significant reduction in waiting time from endoscopy to staging
investigations
� Significant reduction in waiting time from OPC to endoscopy
� Protecting the 2 week pathway has rationalised cancer care and enabled
more patients to be treated within nationally agreed target protocols.
� Further improvements required.

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.

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.
