Patient-reported outcomes for immediate breast reconstruction with mastectomy among breast cancer patients in Pakistan.

Objectives: To evaluate the effect of immediate breast reconstruction with mastectomy in the local population. METHODS: The quasi-experimental, control study was conducted at the Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised patient data from April 2017 to December 2020, of breast cancer patients who underwent mastectomy with or without immediate breast reconstruction. Those who underwent mastectomy were labelled as control group A, while patients with immediate breast reconstruction were labelled as intervention group B. Data was analysed using SPSS 20. RESULTS: Of the 66 patients, 33(50%) were in each of the 2 groups. Group B had significantly more patients aged <40 years than group A (p=0.01), more patients with graduate-level education (p=0.04), and more patients who were either unmarried or divorced (p=0.05) than group A. Group B patients had higher mean scores for satisfaction with breasts (p=0.001) and psychosocial wellbeing (p=0.001) than those in in group A. Mean scores for adverse effects of radiotherapy were significantly higher in group B than in group A (p=0.04). CONCLUSIONS: Better health-related outcomes were reported by patients who underwent immediate breast reconstruction with mastectomy.

Correlation of intra operative specimen imaging with final histopathology in breast conserving surgery for breast cancer.

Objectives: To determine the effectiveness of specimen mammography in breast conserving surgery cases with respect to reduction in margin positivity rate, and to see whether the rate of secondary surgeries is decreased by intra-operative excision based on specimen mammography evaluation. METHODS: The retrospective study was conducted at the Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised data from January 2018 to December 2019 related to all female breast cancer patients who underwent mastectomy or breast conserving surgery with the involvement of specimen mammography. Sensitivity, specificity, positive predictive value and negative predictive value of specimen mammography were calculated. Data was analysed using SPSS 20. RESULTS: Of the 226 patients initially assessed, 65(28.7%) were excluded, and the final sample comprised 161(71.2%) women with mean age 46.71±10.47 years. The sensitivity, specificity, positive predictive value and negative predictive value of specimen mammography for the sample were 65.8%, 80.8%, 54% and 87.3%, respectively. Performing specimen mammography for intra-operative margin assessment in 12 patients was likely to spare one patient from re-excision. CONCLUSIONS: Intra-operative specimen mammography was found to be a reliable tool for assessing margin status.

Is complete pathological response truly a complete response in breast cancer?

OBJECTIVE: To check if complete pathological response in breast cancer is a good prognostic factor. METHODS: The retrospective study was conducted at the Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised data from January 2012 to December 2015 of all patients who received neo-adjuvant chemotherapy and had no distant metastasis at diagnosis. Mastectomy patients were excluded. Complete pathological response was defined as no detectable tumour cell in breast and axilla on pathological examination of the resected specimen. Tumour characteristics and 5-year disease free survival and overall survival were recorded. Data was analysed using SPSS 20. RESULTS: Of the 353 patients whose data was evaluated, 91(25.8%) had complete pathological response. Mean age at diagnosis was 43±10 years. Among them, 62(68%) patients had grade III tumour, 39(42.9%) were negative for oestrogen receptor, 58(63.7%) were negative for progesterone receptor, 25(27.5%) were positive for human epidermal growth factor receptor 2, and 26(28.6%) patients were triple negative. Overall, 28((30.7%) patients had recurrence; 20(71.4%) had distant metastasis, 6(21.4%) had local recurrence, and 2(7.14%) had contralateral cancer. The 5-year disease-free survival and overall survival rates (Kaplan-Meier Survial curve) were 70% (28 patients-recurrence) and 87% (15 patients-deaths), respectively. Conclusion: Despite complete disappearance of tumour, a significant number of patients developed recurrences.

Efficacy of pre - operative axillary ultrasonography in excluding nodal disease: Can it replace sentinel lymph node biopsy in early stage breast cancer?

OBJECTIVE: To determine false negative rate, negative predictive value and the factors predicting false negativity of pre-treatment axillary ultrasound. METHODS: The retrospective study was conducted at Shaukat Khanum Memorial Cancer Hospital, Lahore, Pakistan, and comprised data from January 2019 to December 2020 of patients with normal lymph nodes on ultrasound, tumour stages T1, T2 or T3 having invasive cancer who underwent sentinel lymph node biopsy. Ultrasound findings were compared with the biopsy results, dividing the sample into false negative group A and true negative group B. Clinical, radiological, histopathological parameters and therapeutic strategies were compared between the two groups. Data was analysed using SPSS 20. RESULTS: Of the 781 patients with mean age 49.39±11.51 years, 154(19.7%) were in group A and 627(80.2%) were in group B, with negative predictive value of 80.2%. Initial tumour size, histopathology, tumour grade, receptors, timing of chemotherapy, and type of surgery has significant difference between the groups (p<0.05). Multivariate analysis showed larger, high-grade, progesterone receptor negative and human epidermal growth factor receptor 2 positive tumours were significantly associated with lower false negative rate on axillary ultrasound (p<0.05). CONCLUSIONS: Axillary ultrasound was found to be effective in ruling out axillary nodal disease, especially in patients with high-burden axillary disease, aggressive tumour biology, larger tumour size and higher timour grade.

Breast Cancer Management Consensus By The Society of Surgeons and Surgical Oncology Society of Pakistan.

The Society of Surgeons of Pakistan and The Society of Surgical Oncology of Pakistan with factions from various major centres comprising of surgical oncology, medical and radiation oncology collaborated to reach consensus on breast cancer management guidelines and a framework of "good practice" minimum standards of care. The aim of the task force was to enhance treatment standards, which have a direct correlation with improving patient mortality and morbidity and long-term survival whilst taking into consideration economic limitations of access to leading centers of excellence as well as minimum expertise required in health care. These multidisciplinary guidelines, whilst not exhaustive, aim to provide an algorithm of care for breast cancer patients at tertiary care centres and district level hospitals to provide most appropriate treatment.

Breast conservation surgery (BCS) for breast cancer in a resource limited country - Are we upto the challenge!

OBJECTIVE: To analyse outcomes of breast conservation surgery and to identify the factors that could have affected the outcomes. METHODS: The retrospective study was conducted at the Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised data of breast conservation surgery cases done between January 2011 and October 2014 in order to cover up for the 5-year follow-up of the last enrolled patient. Data, obtained through the institutional information and database system, included disease-recurrence, 5-year disease-free survival and overall survival. Data was statistically analysed using SPSS 20. RESULTS: Of the 553 cases, 417(75%) had no loco-regional recurrence or distant metastasis, while 136(25%) had some form of loco-regional, distant or contralateral metastasis at 5-year follow-up. In patients who had recurrence or metastasis, only progesterone receptor status, nodal status and mode of treatment showed significant association (p<0.05). Mortality at 5-year follow-up was 77(14%). Amongst the patients who died, only progesterone receptor status and nodal status had significant association (p<0.05). Five-year overall survival for the cohort was 476(86%), whereas 5-year disease-free survival was 409(74%). CONCLUSION: Breast conservation surgery was found to have favourable outcomes, while progesterone status, nodal involvement and mode of treatment significantly affected the outcome.

Breast MRI in Invasive Lobular Carcinoma: A Useful Investigation in Surgical Planning?

Magnetic resonance imaging (MRI) is highly sensitive in detecting invasive lobular carcinoma (ILC) of the breast. In our institution, patients who are deemed to be suitable for breast conserving surgery (BCS) with unifocal small ILC on standard imaging are offered breast MRI to exclude multifocal and larger ILC. Our study investigates the usefulness of breast MRI in ILC. A prospective cohort study over a 58-month period, including all consecutive patients with ILC having breast MRI. Primary objective was to find out the proportion of ILC patients where preoperative MRI caused a change in the surgical treatment. Secondary objectives included finding mastectomy rate (initial & final), re-operation rate, cancer size correlation with different imaging modalities and final histopathology, loco-regional recurrence and disease-free survival. A total of 334 bilateral breast MRI were performed including 72 (21.5%) MRI for ILC patients. All these MRI were carried out within 2 week of patients given the diagnosis (median 5.5 days). Age range was 24-83 (median 56.5) years. Nineteen of 72 ILC patients (26.4%) had a change in their planned operation from BCS to a different operation owing to MRI findings (seven patients with multifocal cancers, 10 with significantly larger size of the cancer and two with contralateral malignancy). Initial mastectomy rate was 31.9%, final mastectomy rate was 36.1% and re-operation rate in BCS group was 18.3%. MRI correlated better with ILC histopathology cancer size than mammogram and ultrasound scans. There was no statistically significant difference (p = 0.999) between the cancer size on histology (median 23 mm) and MRI (median 25 mm). However, mammogram (median 17 mm) and ultrasound (median 14.5 mm) scans showed cancer sizes significantly different to final histology cancer size (p = 0.0008 and p = 0.0021 respectively). Over a 44 months median follow-up (range 27-85), 95.8% disease-free survival and 98.6% overall survival have been observed. One out of every four patients (26.4%) with ILC had a change in their planned operation due to MRI findings. A relatively high disease-free survival over a medium-term follow-up proves the oncological safety of MRI in ILC. Our study provides evidence in support of the targeted use of preoperative breast MRI among patients with ILC to improve surgical planning.

Clinicopathological Features and Treatment Outcomes of Male Breast Cancer in Pakistani Population: A 10-Year Retrospective Cross-Sectional Study.

Background: Male breast cancer (MBC) accounts for 1% of global breast cancer cases. On account of its rarity, very few prospective clinical trials have been carried out on MBC. Pakistan has the highest incidence of breast cancer in Asia, but very limited data are available on MBC. Objectives: The objective is to determine the clinicopathological characteristics and treatment patterns of MBC in Pakistani population. Design: This is a retrospective cross-sectional study. Methods: A retrospective cross-sectional study carried out using the cancer database of Shaukat Khanum Memorial Cancer Hospital & Research Center. Men with a histologically proven breast cancer, stage 0 to III disease and requiring surgical intervention were included. The Kaplan-Meier curve and log-rank test were used for survival analysis. Results: Sixty-eight patients with MBC were included with a median age at diagnosis of 55 years. Most patients were stage II (47.1%). Invasive ductal carcinoma (IDC) was the commonest type (89.7%). Estrogen receptor (ER), progesterone receptor (PR), and Her-2 receptor positivity were 92.6%, 86.8%, and 32.4%, respectively. Mastectomy was performed in 95.6% of the cases. Neoadjuvant and adjuvant chemotherapy was administered in 25 (36.8%) and 26 (38.2%) patients, respectively. Fifty-five (80.9%) patients received adjuvant radiotherapy. Most of the patients (89.7%) received tamoxifen. The 5-year overall and disease-free survival was 88.2% and 80.9%, respectively. Patients receiving neoadjuvant chemotherapy had a better overall and disease-free survival (P = .025). Conclusions: Male breast cancer occurs at a relatively earlier age in Pakistani population as compared with Western men. Mastectomy is the preferred surgical option for MBC on account of the advanced disease and delayed presentation. Neoadjuvant chemotherapy has a statistically significant effect on overall and disease-free survival, but in spite of these benefits, it remains underutilized.

Unraveling Stigmas of Male Breast Carcinoma: A Singular Case of Advanced Metaplastic Breast Carcinoma in a Young Male.

Breast carcinoma in males is a rare and unique condition that differs from breast cancer in females and is typically diagnosed at an advanced stage in older male patients. Late diagnosis is often due to the rarity of male breast carcinoma. Among the various types of breast carcinomas, metaplastic breast carcinoma is one of the rarest kind of breast malignancy and is associated with poorer outcomes. This case report presents a singular case of a young male in his early thirties who presented with a breast lump and was diagnosed with metaplastic breast carcinoma. Breast cancer in males is a topic that is often overlooked and lacks extensive research. However, with an increasing incidence of breast carcinoma in males, including even the rarest forms, such as metaplastic carcinoma, and its occurrence in young patients as highlighted in this case report, it is crucial to initiate more discussions, enhance education, and promote further research in male breast carcinoma. In addition, the psychosocial impacts of the disease should be carefully considered, as men with breast cancer face unique emotional challenges that require attention and support.

MRI Features of Synchronous Masses in Known Breast Cancer Patients in Predicting Benign Versus Malignant Lesions: A Case Based Review at Tertiary Care Cancer Hospital.

Sara RehmanObjectives The purpose of this study was to determine the diagnostic accuracy of breast magnetic resonance imaging (MRI) in classifying incidental satellite masses in biopsy-proven breast cancer patients as benign or malignant masses and assessing its impact on surgical management of these patients. We also analyzed the incidence of MRI-detected lesions, which were thereafter assessed with second look ultrasound (US). Materials and Methods A retrospective study was performed on breast cancer patients presenting from August 01, 2016 to July 31, 2019, with satellite masses seen on base line MRI. Satellite masses were classified as benign and malignant based on MRI features of shape, margin, T2-weighted imaging signals, internal enhancement pattern, enhancement kinetic curves, and diffusion restriction. This was compared with results of histopathological examination. The number of MRI-detected lesions, location of the satellite mass, and type of surgery were also documented. Results Out of 400 breast cancer patients undergoing MRI breast, 115 patients had multiple masses. Histopathological diagnosis was available for 73 patients; and a total of 93 satellite masses were evaluated. There was evidence of additional masses on second look ultrasound in 21 patients. Of 72 masses classified as malignant on MRI, 58 showed malignant pathological outcome; while out of 21 masses characterized as benign on MRI, 18 turned out to be benign on histopathology. A statistically significant association was found between MRI features and pathological outcome of satellite masses ( p = 0.001). The sensitivity, specificity, positive and negative predictive values, and accuracy were 95%, 56%, 80.56%, 85.7% and 81.7%, respectively. Based on these findings, modified radical mastectomy (MRM)/mastectomy was done for 42 patients, 5 patients underwent lumpectomy limited to a single tumor, extended resection done for 14 patients, 5 underwent bilateral breast conservation surgery (BCS), BCS for contralateral breast done for 4 patients undergoing ipsilateral MRM/mastectomy, and bilateral MRM/mastectomies were performed for 2 patients. One patient was lost to follow up. Conclusion Breast MRI is the most sensitive modality for the assessment of breast cancer and plays an essential role in the detection of additional tumor foci. These findings can modify the surgical approach in these patients. However, considering the low specificity, biopsy of satellite masses is imperative to determine the most appropriate surgical plan.

Benchmarking Excellence: Evaluating Advanced Breast Carcinoma Care in Pakistan's Largest Cancer Hospital Against the National Institute for Health and Care Excellence (NICE) Guidelines.

Introduction Breast cancer is the most common type of cancer worldwide, and even with all the screening and education, great numbers of diagnoses are made in advanced stages. Additionally, patients in remission always remain at risk of relapse and metastasis. Pakistan has the highest incidence of breast cancer among Asian countries. The purpose of this clinical audit was to compare data from the largest cancer hospital in Pakistan with international standards to provide room for quality improvement. Methods A retrospective review of patients with advanced breast carcinoma over a period of six months was done. Permission was obtained from the Quality Assurance and Patent Safety Department before the commencement of the audit. Standards Data obtained were audited against nine standards of four different categories from the National Institute for Health and Care Excellence (NICE) guidelines on advanced breast carcinoma. Results For the diagnosis and assessment category, for which a target of 100% was set, 99.66% was achieved; for disease monitoring, for which a target of 100% was set, 91.8% was achieved; for systemic disease-modifying therapy, for which the majority was the target, only 1% was achieved; for managing complications, for which a target of 100% was set, 71.8% was achieved. Conclusion Continuous research and breakthrough advancements have made health care an ever-evolving field. Clinical audits like these that compare international standards with local data are beneficial and lead to quality improvement. They highlight issues that may be overlooked otherwise, raise questions that may never be asked, and may inspire prospective research studies. Limitations of the audit were that this clinical audit was conducted outside of the NHS where NICE guidelines are not followed and local guidelines differ from NICE guidelines.

Follicular Lymphoma of Breast: A Case Report from Pakistan.

Introduction: Breast lymphoma (BL) is a rare breast tumour and accounts for <1% of all breast malignancies. It is further categorised into primary BL and secondary BL. This manuscript presents a case report of a patient diagnosed with secondary BL. Case Description: A 51-year-old female presented in the one-stop breast clinic with 6-month history of having a static and painless left breast lump. Mass was firm, non-tender and 2 cm in size. It was not adherent to skin or muscle and it was present in the upper outer quadrant of the left breast. Mammo-sonography revealed a circumscribed mass of 17 mm in the outer quadrant of the left breast. There were enlarged ipsilateral lymph nodes. Core biopsy suggested atypical lymphoid infiltrates. She underwent wide local excision of breast and axillary nodal mass. The definitive histological diagnosis revealed non-Hodgkin's follicular lymphoma grade 2/3. Staging computed tomography scan features were suggestive of cervical lymphadenopathy. Hence, staging workup proved this to be a case of secondary BL. Practical Implication: The early diagnosis of BL is highly relevant. Its diagnosis is challenging due to non-specific clinical presentation and imaging features. Commonly FL is diagnosed on excisional biopsy or after wide local breast mass excision. Primary and secondary lymphomas, though rare, should be considered in the differential diagnosis of breast malignancies.

Isotope-Only Localization for Sentinel Lymph Node Biopsy - Medium-Term Oncological Outcomes.

AIMS: Isotope and blue dye dual localization in sentinel lymph node biopsy (SLNB) gives localization rates of over 98% and is the recommended technique. However blue dye risks a range of adverse reactions. Since 2010, for clinically node negative disease, we have only used blue dye if there is no clear isotope signal at surgery. METHODS: Electronic records of patients who underwent isotope-only SLN localization between July 2010 and April 2012 were examined. Data were collected on localization and oncological outcomes. RESULTS: 426 patients were included. Isotope-only localization rate was 97.4% (415/426). The median follow-up was 63.5 months (IQR: 60.7-70.9). Median age was 57 (IQR: 48-67). Median SLN yield was 2 (range: 1-5). Axillary recurrence rate was 1.4% with median time to recurrence of 39.3 months. In-breast recurrence, distant disease and contralateral breast cancer rates were 2.8%, 7%, and 1.9% respectively and 15 (3.5%) patients died of metastatic breast cancer. CONCLUSION: Isotope-only SLNB has a comparable localization rate to dual isotope/blue dye SLNB and can spare the risk of blue dye adverse reactions. The low axillary recurrence rate, maintained to more than 5 years, confirms that isotope-only SLNB is a feasible and safe alternative to dual blue dye/isotope localization.

Correlation of Breast Density Grade on Mammogram With Diagnosed Breast Cancer: A Retrospective Cross-Sectional Study.

Objective The objective of this study is to determine any association between mammographic density (MD) and breast cancer in Pakistani population. The study will also investigate relationship between mammographic breast density, clinical characteristics, and molecular tumor markers of the disease. Methods A retrospective review of data was carried out from January 2020 to December 2020 with stage 0-3 patients with histologically proven breast cancer included in the study. Mammograms were reviewed and density grade was recorded in accordance with "Breast Imaging Reporting and Data System (BIRADS)" guidelines. Patient age, tumor, and receptor characteristics were studied and their association with mammographic density was investigated by using chi-square test. P-value ≤0.05 was considered statistically significant. Results A total of 361 patients were included with a mean age of 46 years. The frequencies of BIRAD categories were as follows: category A: 8.9%, category B: 43.2%, category C: 33.5%, and category D: 14.4%. Cumulative frequency of categories B and C was 76.7%. There is a statistically significant p-value ≤0.05 association observed between age, estrogen receptors (ER) status, and T-stage versus MD. Also, majority of our patients were in T-stage category 2 or 3, which can easily be picked on mammogram. Conclusion Most of the breast cancer patients in our population had a mammographic density of B or C, indicating that breast cancer is more common in dense breasts. Strong significant association of mammographic density with age, ER status, and tumor stage was found in our population. Future studies need to address and confirm MD and its association with subtypes and aggressiveness of breast cancer.

A leafy surprise: Case report of male breast malignant phyllodes.

INTRODUCTION AND IMPORTANCE: Phyllodes tumor is a biphasic fibroepithelial tumor which accounts for less than 1% of all breast neoplasms. We aim to raise awareness among clinicians that a male breast lump may be indicative of underlying sinister pathology and therefore, should be investigated thoroughly. CASE PRESENTATION: A 62 year old male presented in clinic with right beast lump for the last 6 weeks. A preoperative diagnosis of spindle cell tumor was made on core needle biopsy. Neoadjuvant chemotherapy was administered in order to downsize the tumor as it was inseparable from underlying muscle. A post-operative diagnosis of malignant phyllodes was made following mastectomy. As the tumor was 1 mm from the deep margin, adjuvant radiotherapy was administered. CLINICAL DISCUSSION: Differential diagnoses of malignant phyllodes include metaplastic carcinomas metastatic/primary sarcomas and fibroadenomas. Metaplastic carcinomas are morphologically heterogeneous and include adenosquamous carcinoma, squamous cell carcinoma and spindle cell carcinoma. In some malignant phyllodes, extensive stromal proliferation can make detection of epithelial component very difficult. This highlights the limitation of core biopsy in establishing an accurate preoperative diagnosis. The standard treatment for phyllodes treatment is surgical resection with margins of 1 cm or more. Adjuvant radiotherapy is used in cases with threatened margins. CONCLUSION: Malignant phyllodes tumor of breast can exist in men, and its accurate pre-operative diagnosis is difficult given the limitations of core biopsy. This case report draws attention to the challenges associated with the diagnosis of this rare condition and highlights the role of different treatment modalities in its management.

Invasive carcinoma in accessory axillary breast tissue: A case report.

INTRODUCTION: Accessory or ectopic breast tissue is an aberration of normal breast development. It is known to be a rare entity present anywhere along the embryologic mammary streak or milk line but more common in axilla. PRESENTATION OF CASE: We report a case of 36 year old female with accessory breast carcinoma who presented with a progressive lump in her left axilla for 1 year. On examination a 2 cm solitary mass was palpable in axilla. Ultrasound confirmed a 19 mm mass with no other lesion in breast and axilla. Core biopsy showed invasive ductal carcinoma. She was discussed in multidisciplinary board meeting and was offered upfront surgery with excision of accessory breast tissue and sentinel lymph node biopsy. Axillary lymph node dissection was omitted following ACOSG Z0011 criteria. She was offered adjuvant chemotherapy and radiation post operatively along with endocrine treatment as she was hormone receptor positive. DISCUSSION: Accessory breast development is hormone dependent just like normal breast. Breast cancer in accessory breast tissue is very rare. The incidence is around 6%. Most common pathology is invasive ductal carcinoma (50-75%). The most common location is axilla (60-70%) although it can present in other less common locations like infra-mammary region (5-10%) and rarely in thighs, perineum, groin, and vulva. CONCLUSION: Since accessory axillary breast tissue is out of the image of screening breast examination, it is necessary for the oncologists to be aware of this entity and associated pathologies. Their preventive excision in high risk women can also be considered.

The use of abbreviations in medical records in a multidisciplinary world--an imminent disaster.

Abbreviations are commonly used in the medical world to save time and space whilst writing in the patients' medical records. As various specialties have evolved, each has developed a collection of commonly used abbreviations within its practice, which may not be recognizable to those not working within the same field. The purpose of this study was to assess whether we, the multidisciplinary team members, correctly interpret the abbreviations used in the medical records. We analysed one week of orthopaedic surgical medical records for the use of abbreviations and assessed their appreciation by other members of the multidisciplinary team by means of a standardized questionnaire. We found great variability in the understanding of these abbreviations by different groups of health care professionals. As expected, the orthopaedic surgeons produced significantly more right answers when compared to the other groups, but even they could correctly interpret just over half (57.24 per cent) of the abbreviations. There were many misinterpretations of the abbreviations across the specialties posing imminent clinical risk. Whilst abbreviations may indeed save time, the observed inter-group variation in correct interpretation of these abbreviations is unacceptable. We recommend that the abbreviations have no place in the multidisciplinary world and their continued use will only lead to eventual clinical error.
