Evaluation of Precancerous Breast Lesion Upgrade Rate

Background: Breast imaging guided core-needle biopsy enable the assessment of suspected precancerous lesions. In some precancerous lesion there is a risk of upgrading to cancer after surgical removal. This study was conducted to determine the upgrading rate of CNB-diagnosed precancerous breast lesions. Methods: A retrospective study was conducted to examine the data of patients who had undergone core needle biopsy from April 2016 to March 2019 at the Radiology Department of the Breast Clinic of Motamed Cancer Institute and whose pathological reports were indicative of a precancerous lesion such as atypical ductal hyperplasia, sclerosing adenosis, flat epithelial atypia or papillary lesion and had undergone surgery for this lesion. The upgrading rate and its related factors such as the size of the lesion, patient’s age, family history of breast cancer and method of core-needle biopsy were analyzed in SPSS software. Results: A total of 241 patients were recruited with a pathological report of pre-cancerous predisposing lesions. The mean age of the patients was 42.14 years and the highest upgrading rates in the analysis were observed for papillary lesion (19.3%) and atypical ductal hyperplasia, (21.4%), while the upgrading rates were (1.2% ) for sclerosing adenosis and (0%) for flat epithelial atypia. Data analysis showed that the lesions’ upgrading rate correlated with the lesion’s size (P=0.005).Conclusion: The findings of this study showed that size of the lesions increase the risk of upgrading to cancer, which is much higher in papillary lesion and atypical ductal hyperplasia compared to sclerosing adenosis and flat epithelial atypia. It seems that surgical excision of the entire lesion in patients with larger mass size may decrease the upgrading rate of cancer. Conducting specific studies on each distinct lesion can help yield more conclusive results.

Spinal Accessory Nerve Duplication – A Rare Anatomical Consternation During Neck Dissectio

Prevention of the spinal accessory nerve (SAN) is an indispensable aspect of the functional neck dissection surgery to avoid highly disabling shoulder syndrome postoperatively. This requires comprehensive knowledge of the anatomy of SAN and its variations. Rare anatomical variations like SAN duplication can result in an inadvertant injury to the SAN. We report a case of duplication of SAN, which was encountered while doing a functional neck dissection surgery for oral squamous cell carcinoma. No iatrogenic injury occurred during the surgery and neither there was any SAN dysfunction post-operatively. Meticulous dissection and consistent identification of SAN, along with vast anatomical knowledge is the key to the preservation of the nerve during the surgery. This report aims to broaden our anatomical knowledge of SAN and also discuss the clinical implications and literature pertaining to the duplication of SAN.

Rare Case of Mediastinal Myeloid Sarcoma

Myeloid sarcoma is a rare tumor mass with extra medullary growth pattern, composed of myeloblast or immature myeloid cells. Myeloid sarcoma (MS) is a distinct clinical presentation of acute myeloid leukemia (AML) where less than 1% of patients present with prominent extra medullary disease which most commonly involves the bone, skin, lymph node, soft tissues, gastrointestinal tract or testes. The recommended treatment regimen in isolated myeloid sarcoma or with bone marrow involvement is upfront systemic chemotherapy. We report a case of a young female with anterior mediastinal mass diagnosed as myeloid sarcoma which was refractory to chemotherapy.

Demography and Outcome of Cancer Patients with COVID-19: A Retrospective Cohort Study in Dharmais National Cancer Center Indonesia

Introduction: Cancer patients have an increased risk of morbidity and mortality due COVID-19 partly due to their immunocompromised status. We aimed to investigate the associations of clinicopathological factors and survival outcomes in cancer patients with COVID-19. Methods: This was a retrospective cohort study comprised of cancer patients treated in Dharmais National Cancer Center, Indonesia. Main inclusion criteria were pathologically confirmed malignancy with positive results of RTPCR COVID-19 tests. Results: A total of 16,511 visitors had visited and registered for RTPCR test in Dharmais National Cancer Center from May 2020 to January 2021. Logistic regression showed that male gender (p-value = 0.019; OR = 1.732), haematological type of malignancy (p-value <0.001; OR = 3.073), patients not underwent cancer therapy (p-value = 0.008; OR = 0.485), low RTPCR Ct values (p-value = <0.001; OR = 3.340), poor performance status (p-value = <0.001; OR = 8,194), and disease severity (p-value = <0.001; OR = 5.448) were associated with mortality. Conclusion: Overall mortality rate in Dharmais cancer patients (25%) was higher than other cancer patients treated in other hospitals in Asia. Moreover, the mortality rate was similar across all age groups. Poor survival in young age might be explained by the fact that median age of cancer patients was 46 years old. In addition to male gender, cancer patients with low Ct values and having delayed cancer treatment were vulnerable groups of having poor outcomes when diagnosed with COVID-19. Long-term follow-up is required to examine the survival rate in cancer patients with COVID-19.

Epidemiological Profile and Clinicopathological Correlates of Triple Negative Breast Cancer Patients at Regional Cancer Centre

Background: Breast Cancer is the most common cancer among woman worldwide. In India breast cancer remains the leading cause of both incidence and mortality. Triple negative breast cancer is more difficult to treat as it does not respond to hormone therapy medicines or medicines that target receptor proteins (like HER 2 Neu). It is crucial for the physician to know the status of the disease as the patient can be subjected to a whole new avenue of treatment. The present study was done to assess the epidemiological profile and clinicopathological correlates of patients of triple negative breast cancer. Material and Methods: This retrospective study was carried out in Acharya Tulsi Cancer and Research Institute located in the state of Rajasthan, Bikaner, India, among Ca Breast patients presenting to Medical Oncology, Radiation Oncology and Surgical Oncology outdoor & indoor from April 2016 to March 2017. Out of the total 1017 patients of carcinoma breast 957 were included in this Study. Exclusion criteria was non availability of ER, PR, HER2 neu status reports because of various reasons like affordability. Out of the total 957 patients 249 were found to be triple negative. Statistical analysis was done using IBM SPSS version 21. Results: Mean age of the patients was 46±11.23 years. Out of total 249 patients of triple negative breast carcinoma, 91 (%) were found to have had clinical staging I and II (Early stage) and 158 (%) patients were found to have clinical staging III & IV (Late Stage). Mean size of the tumor was 3.6±1.94cm. 151 (60.6%) were pre-menopausal, 103 (41.4%) and 12 (4.8%) patients had positive family history. All of or patients diagnosed to have Ductal type of carcinoma. Lympho-vascular invasion was seen in 51 (20.5%) patients and High grade Histological Grading was seen in High Grade 169 (67.9%) patients. 172 (69.1%) undergone MRM (Modified Radical Mastectomy) and BCS was done in 74 (29.7%) patients. After comparison of triple Negative Breast Cancer with non-triple Negative Breast Cancer, lower age, later stages (III and IV), pre-menopausal status and high grade (on histology) were significantly more in negative type of Ca breast. Occurrence of early Menarche (< 13 Years) and history of OC pills used was almost equal in both the groups. Conclusion: Triple Negative Breast Cancer was found to present at an earlier age and more in pre – menopausal women. Such patients presented with a higher histological grade of tumor and late stage of presentation. There was no statistically significant association between TNBC and age of menarche, use of OC pill, previous exposure to radiotherapy and positive family history in first degree relative.

The Role of Immunohistochemistry in the Workup of Malignant Neoplasms of Unknown Primary Origin at Khartoum Oncology Hospital

Background: Carcinoma of unknown primary origin (CUP) comprises various malignancies classified by detection of tissue-specific genes through immunohistochemistry (IHC). We aimed to explore the role of available immunohistochemical markers in diagnosing and classifying malignant neoplasms of unknown primary origin.Methods: A cross-sectional study included 141 patients diagnosed histologically as CUP and referred to the Histopathology and Immunohistochemistry Department, Khartoum Oncology Hospital, from 2012 to 2017. Hematoxylin and Eosin (H&E) and immune stained slides used in the workup were reviewed and classified into the main histologic types of CUP. Data were -analyzed by SPSS. Results: Out of 4436 cases, CUP represents (3.2%). The age group (60-69) years have the highest percentage (20.13%), with male predominance (51.77%). Lymph nodes represent (41.84%) followed by the liver (12.77%), spine (3.55%), and lungs (2.13%). Adenocarcinoma (75.89%) was the most common subtype, followed by undifferentiated neoplasm (14.18%), squamous cell carcinoma (7.09%), and carcinoma with neuroendocrine differentiation (2.84%). In 70 cases (49.6%) of the study cases, the primary site was determined, (17.7%) were given an only differential diagnosis, and in (32.6%) the origin remains unknown. Conclusions: CUP cases during the study period are infrequent (3.2%), and the primary origin was determined in nearly half of patients by the available immune markers. CUP’s common histological types were adenocarcinoma, undifferentiated neoplasm, squamous cell carcinoma, and carcinoma with neuroendocrine differentiation. The most common presenting sites were lymph node, liver, spine, and lungs.

Retinoblastoma in South Asia: A Scoping Review

Introduction: Pakistan, Indonesia, Bangladesh and the Philippines are listed as among the six Asian countries which will be the sources of 43% or almost 4000 new cases of the estimated world’s retinoblastoma cases in 2023. Materials and Methods: Scoping review of literatures using the databases of Pubmed, EMBASE, Scopus, Science Direct, Google scholar and Web of Science databases as well as local and regional databases on clinical features, treatment and outcomes of retinoblastoma patients from Pakistan, Indonesia, Bangladesh and the Philippines was done. A descriptive analysis using the 2017 retinoblastoma database of the Global Retinoblastoma Study Group (GRSG) was added to supplement data for Bangladesh, Indonesia and the Philippines. Results: A total of 17 articles were included in this review. There were 696 retinoblastoma patients involving at least 859 eyes seen in Pakistan from 1997 to 2018 and included in the 7 articles reviewed. There were 617 retinoblastoma patients involving at least 677 eyes seen in Indonesia from 2003 to 2018 and included in the 8 articles reviewed and the GRSG’s database. There were 161 retinoblastoma patients involving 221 eyes identified in the descriptive analysis of the GRSG’s database for Bangladesh. And there were 226 retinoblastoma patients involving 297 eyes seen in the Philippines from 1998-2020 from the 2 articles from the Philippines and the GRSG’s database. Discussion: Lack of awareness on the disease, distant centers, expensive service and cultural unacceptability of treatment were the commonly cited reasons for late consult. However, non-standardized and poor clinical reporting and monitoring, and non-standardized treatment protocols were also contributory to the low survival rates. The current management outcomes of retinoblastoma from the four countries are alarmingly below par with developed countries, India and China. Conclusion: Although advances had been made in the management of retinoblastoma, delay in consultation which often leads to advanced disease was still common. This contributes to low survival rates in the four countries.

Real World Data of Response of Trastuzumab Based Chemotherapy in Locally Advanced HER2 Positive Breast Cancer from a Developing Country

Background: Data regarding pathologic response of Trastuzumab based chemotherapy in locally advanced HER2 positive breast cancer in neoadjuvant setting is scarce. Methods: A retrospective analysis was conducted from January 2014 to January 2019 at a tertiary cancer care centre in North India and 81 breast cancer patients who underwent neoadjuvant chemotherapy were included. The clinical and pathologic characteristics, response, toxicity and survival data was collected, collated and analyzed. Results: The most commonly observed tumor characteristics at baseline were clinical stage T4 (72.8%), nodal stage N2 (40.7%), invasive ductal carcinoma on histology (98.8%), grade 3 (66.7%) and hormone receptor negativity (54.3%). In terms of post treatment characteristics, a higher incidence of partial response (55.6%), post treatment tumor stage ypT0 (45.7%), nodal status ypN0 (54.3%), absence of extracapsular invasion (77.8%) and absence of pathologic complete response (pCR, 63%) were observed. pCR was attained in 30 patients and was most commonly associated with clinical tumor stage T4 (26/30), nodal stage N2-N3 (19/30), grade 3 (21/30) and hormone receptor negativity (20/30). Altogether, 19.75% had grade 3/4 adverse events. At 6 years, 86% v/s 61% patients were disease free (p=0.037) and 93% v/s 79% patients (p=0.181) were alive in the pCR and no pCR groups, respectively. Conclusion: Even in locally advanced breast cancer (LABC), Trastuzumab had good response in terms of pCR and survival outcomes. Thus, one can be encouraged to use this single HER2 blockade if dual blockade is not feasible in HER2 positive LABC in the neoadjuvant setting.

This disruption to cancer screening services may have a significant impact on patients, health care practitioners, and health systems. Through this paper, we aim to offer a comprehensive view on the impact of COVID-19 on cancer screening in India and offer potential solutions to the problems arising out of the COVID-19 pandemic in cancer screening and prevention.

Technical Challenges to the Delivery of Quality Radiation Therapy During the COVID-19 Unlock Period: Medical Physics Perspective

The Covid-19 onset was very pandemic for all of society all over the world. To overcome this state of affairs, the country’s government had done the lockdown in their respective countries. The lockdown helped the people from spreading the Covid-19 virus among people, however, it affected another part of life such as people becoming unemployed. The health care sector was affected a lot by the lockdown as the patient faced lots of problems such as reaching the hospital, meeting the concerned staff, getting the treatment on time, etc. Covid-19 affected the cancer patients most, during the lockdown. After awareness of Covid-19, when the world has started towards the unlock down. With the little negligence of people, the world has started facing the peak of Covid-19. And, there was more crowd in the health care sectors, therefore the hospital staff got infected a lot, as the patient treatment cannot be carried out from home. Cancer patient treatment, which comes under radiotherapy, has already existed in chronic medical conditions, such as lung cancer patients, esophagus cancer patients, heart disease patients, etc, has a higher risk of Covid-19 infection. During treatment, when such a patient comes in contact with a radiation oncologist, medical physicist, and radiation technologist, then some of the staff get infected through patients. To prevent such spread, all the medical staff should strictly follow the rules made for staff. In this article, we are sharing the challenges for the medical physics team and some suggestions during patient care.
