Breast cancer in India: where do we stand and where do we go?

Burden of female breast cancer in India: estimates of YLDs, YLLs, and DALYs at national and subnational levels based on the national cancer registry programme

PURPOSE

Female breast cancer (BC) is the leading cause of cancer incidence and mortality in India, and accounted for 13.5% of new cancer cases and 10% of cancer-related deaths in 2020. This study aims to estimate and report the female BC burden in India at state level from 2012 to 2016 in terms of years of life lost, years lived with disability, and disability-adjusted life years (DALYs), and to project the burden for the year 2025.

METHODS

The cancer incidence and mortality data from 28 population-based cancer registries were analysed. The mean mortality to incidence ratio was estimated, and mortality figures were adjusted for underreporting. The burden of female BC was estimated at national and subnational levels using Census data, World Health Organisation's lifetables, disability weights, and the DisMod-II tool. A negative binomial regression is employed to project burden for 2025.

RESULTS

The burden of BC among Indian women in 2016 was estimated to be 515.4 DALYs per 100,000 women after age standardization. The burden metrics at state level exhibited substantial heterogeneity. Notably, Tamil Nadu, Telangana, Karnataka, and Delhi had a higher burden of BC than states in the eastern and north-eastern regions. The projection for 2025 indicates to a substantial increase, reaching 5.6 million DALYs.

CONCLUSION

The female BC burden in India was significantly high in 2016 and is expected to substantially increase. Undertaking a multidisciplinary, context-specific approach for its prevention and control can address this rising burden.

Pan-cancer Analysis Combined with Experiments Deciphers PHB Regulation for Breast Cancer Cell Survival and Predicts Biomarker Function

BACKGROUND

Breast carcinoma has become the leading fatal disease among women. The location of prohibitin in the chromosome is close to the breast cancer susceptibility gene 1 (BRCA1). Accumulated research reported that prohibitin could interact with a variety of transcription factors and cell cycle-regulating proteins.

OBJECTIVE

This present study aims to comprehensively explore and reveal the biological functions of prohibitin on breast cancer via The Cancer Genome Atlas (TCGA) and validation experiment in vitro.

METHODS

Exploring the expression level of prohibitin across 27 tumors based on the TGGA database by bioinformatic methods and its relationship with tumor immune infiltration. Furthermore, we thus analyzed the biological roles of prohibitin on human breast cancer cell line MCF- 7 with pEGFP-prohibitin overexpression plasmid by western blotting and transwell-assay.

RESULTS

Firstly, we found prohibitin is overexpressed in most tumors based on The Cancer Genome Atlas database, and the negative relationships between prohibitin and tumors infiltrating lymphocytes including B lymphocyte, CD4 T lymphocyte, CD8 T lymphocyte, Neutrophil, Macrophage and Dendritic, and its significant correlation with the prognosis of human cancer. In vitro, expression not only inhibited cell viability and invasive abilities but also increased the apoptosis percentage of cells with a decreased percentage of the S phase and an increased G2 phase. The reduction of Bcl-2 was observed when prohibitin was upregulated, although the expression of E2F-1 did not change.

CONCLUSION

Although prohibitin is over-expressed in various cancer types, it functions as an important tumor suppressor that may suppress breast cancer cell proliferation and the invasive ability of MCF-7 by influencing its DNA synthesis and promoting cell apoptosis. All these may be likely associated with P53, erbB-2, and Bcl-2.

Pattern of Surgical Diseases Affecting Females in a Teaching Hospital in Central India: A Demographic Study

Introduction  Despite progress in eliminating the social and health disparity between men and women during the last century, gender equality remains an elusive goal, particularly in the developing world. This gender-based bias has been found to directly result into poor health outcome in females. Hence, it is vital to know the number and pattern of surgical diseases affecting females in any setup, so as to improve their admission rates and reach out to this neglected half of population. Materials and Methods  This was a demographic study done at a teaching hospital in Central India from January to June 2020. Data of patients discharged from female surgery ward were collected from medical record department. Age, diagnosis, urban-rural distribution, and length of hospital stay of patients were noted, and data were analyzed statistically. Results  A total of 187 patient records were studied, which revealed that the mean age of the patients was 40.35 years; maximum patients were of gastrointestinal surgery (53.42%) in which the most common diagnosis was cholelithiasis (25.13%). Urological diseases (15.50%), breast diseases (12.83%), perianal disease (9.09%), and thyroid diseases (5.34%) were found in decreasing order of frequency. Overall hospital stays of patients ranged from 1 to 14 days with average stay of 6.35 days. Conclusion  In our study, cholelithiasis was found to be the most common surgically treated disease followed by urological diseases. Breast symptoms, although commonly affecting females, did not turn into admissions as there remains a social taboo attached to it. Breast cancer still presents late, despite being the most common cancer in females in India. Approximately 65% patients were discharged within first 5 days of their admission, which indicates good hospital care and improves patient satisfaction levels. Still there is greater need for public health efforts to improve the monitoring, safety, and availability of surgical services to female patients.

Link between Blood Cell-Associated Inflammatory Indices and Chemotherapy-Induced Hyperglycemia in Women Affected with Breast Cancer: Clinical Studies

Krishna PrasadBackground  Development of treatment-induced hyperglycemia/diabetes is a considerable problem in women undergoing chemotherapy for breast cancer. In this study, baseline levels of blood cell-associated inflammatory indices (BCAII) were analyzed to understand their role in the development of treatment-induced hyperglycemia and diabetogenesis. Materials and Methods  This was a retrospective study, and information on women who were normoglycemic and nondiabetic and of women who were diabetic at the beginning of the treatment were collected from files. Demographic, pathology-related details, and complete blood profile were noted. Neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), platelet-to-lymphocyte ratio (PLR), and systemic inflammatory index (SII) which indicate BCAII were calculated. Demographic details were subjected to frequency and percentage, while blood parameters were subjected to one-way analysis of variance followed by post hoc Bonferroni's multiple comparison tests. A p -value of <0.05 was considered significant. Results  The results indicated that a significant difference in levels of total count ( p  < 0.035), neutrophil, lymphocyte, and platelets ( p  < 0.001) were observed. Regarding BCAII, when compared with women who were normoglycemic at the end of treatment, NLR, dNLR, PLR, and SII were significantly high for people who were known diabetics at the beginning of treatment ( p  < 0.001). The dNLR ( p  = 0.0008), PLR ( p  < 0.001), and SII ( p  < 0.001) were significant for people who developed secondary hyperglycemia/diabetes, while only dNLR was significant for people who progressed from normal to prediabetes stage ( p  = 0.049) Conclusion  To the best of the authors' knowledge, this is the first study that indicates difference in baseline BCAII and development of treatment-induced hyperglycemia/diabetes indicating that underlying low levels of inflammation may contribute to diabetogenesis in women affected with breast cancer.

T, G. B, G. A. V, M. S, K. K. Expression of fascin in Invasive mammary cancer - A study at a Tertiary care centre in Southern India

Introduction and Aim: Breast cancer is the commonest malignancy in women. Most women do not die of the primary tumor but from metastasis and local invasion. Augmented motility of cancer cells corroborates with greater metastatic potential, that is brought about by actin cytoskeleton. Fascin, a cytoplasmic F-actin-bundling protein that cross-links actin filaments and its overexpression is strongly associated with metastatic progression and poor prognosis. The present study aims to determine the fascin protein expression by immunohistochemistry in invasive breast carcinoma and to correlate the same with the existing prognostic factors.   Methods: Immunohistochemical expression of fascin in 100 cases of invasive mammary carcinoma was studied. Data collected was scored based on intensity and statistically analyzed using GNU-PSPP version 0.10 software. To determine significant clinico-pathological differences between fascin expression in positive and negative tumors, Pearson Chi-square test was used.   Results: It was noted that 22 of the 100 cases were positive with a score of 3 or more. A significant association of nodal status with fascin (p value <0.05) was noted. Higher proportion of fascin positive tumors were node negative. There was an inverse correlation between ER/PR/HER2 status and fascin positivity. The corresponding p values for ER, PR and HER2 with fascin were <0.05. On the contrary 12(57.15%) of the 21 triple negative cases were fascin positive. The p value was <0.001 indicating a significant correlation between molecular subtypes and fascin expression. A more of the fascin positive tumors fell in the triple negative category.   Conclusion: Higher proportion of fascin positive cases in the node negative category, an inverse correlation between fascin expression and individual ER/PR, HER2 expression and larger number of fascin positive cases in the triple negative category. These findings point an association of fascin with aggressive breast carcinomas.

Prospective Evaluation of Response Outcomes of Neoadjuvant Chemotherapy in Locally Advanced Breast Cancer

Introduction Breast cancer is a global health problem, with more than 1 million cases of breast cancer diagnosed worldwide each year, and is the most common cancer among Indian women. Locally advanced breast cancer (LABC) accounts for 10-20% in the Western world while in India it accounts for 40-50% of all cases. Locally advanced breast cancer is a very common clinical scenario especially in developing countries possibly due to various factors like lack of education and poor socioeconomic status. Women with the locally advanced disease require multimodality therapy and coordinated treatment planning. This study aimed to prospectively study the clinical profile of the LABC patients presenting to our institute and also to evaluate the role of neoadjuvant chemotherapy in downstaging the tumor. Materials and Methods Seventy patients diagnosed with locally advanced breast cancer were enrolled in this prospective study. After thorough preoperative workup, patients were either taken up for upfront surgery or neoadjuvant chemotherapy followed by surgery. Post chemotherapy clinical response of the tumor and postoperative histopathological evaluation of the specimen was performed. Results The mean age of the patients in our study was 45 years. Out of 70 patients, 18 underwent upfront surgery, and 52 received neoadjuvant chemotherapy followed by surgery. A total of 44 cases had a clinical response to chemotherapy with 9% having a complete response. The incidence of margin positivity in the postoperative specimen was significantly lower in patients who received neoadjuvant chemotherapy. Conclusion  Locally advanced breast cancer accounted for the predominant number of breast cancer patients mostly females in their middle age. Neoadjuvant chemotherapy was effective in downstaging the tumor in the majority of cases, although complete clinical response was lower in our study. The rate of margin positivity in mastectomy specimens can also be reduced if chemotherapy is considered prior to mastectomy.

Relationship of vitamin D deficiency with mammographic breast density and triple-negative breast cancer: A cross-sectional study

Background As breast epithelium is affected by vitamin D, it may have a direct effect on breast density and the risk of breast cancer. Our aim was to study the serum levels of vitamin D in patients with malignant and benign breast disease, and to study the association, if any, between vitamin D levels, mammographic breast density (MD) and molecular subtypes of breast cancer. Methods In this cross-sectional, observational study, we enrolled 162 consecutive adult women with benign and malignant breast masses subjected to mammography and core-needle biopsy. Serum levels of vitamin D were estimated and correlated with MD and with immunohistochemical subtyping of breast cancer. Results The mean vitamin D level in these 162 patients was 12.44 (5.88) ng/ml, with vitamin D deficiency seen in 98%. The mean (SD) vitamin D level in MD type 1 was 16.19 (4.62) ng/ml and it decreased to 7.54 (2.58) ng/ml in MD type 4. High MD was associated with significantly lower vitamin D levels. The mean vitamin D level in patients with benign breast disease (n=102) was 13.73 (5.68) ng/ml, while it was significantly lower in patients with breast cancer (n=60) at 10.26 (5.61) ng/ml. Among patients with breast cancer, the good prognosis luminal A molecular subtype had mean vitamin D level of 12.94 (6.16) ng/ml, whereas the poor prognosis triple-negative subtype had a significantly lower value of 7.68 (3.42) ng/ml. Conclusion Our study shows that vitamin D deficiency has a significant relationship with breast cancer (v. benign breast disease), high MD (showing increased breast cancer risk) and poor prognosis triple-negative breast cancer. Vitamin D deficiency could be an important, potentially modifiable, risk factor for the prevention of breast cancer in susceptible populations.

Fine-Needle Aspiration Cytology versus Core-Needle Biopsy for Breast Lesions: A Dilemma of Superiority between the Two

INTRODUCTION

Core-needle biopsy (CNB) is a minimally invasive procedure used in preoperative diagnosis of breast lumps. It has been seen that in few years, the CNB seems to be replacing the fine-needle aspiration cytology (FNAC), although no study had yet conclusively proved a superiority of one over the other.

AIMS AND OBJECTIVES

The aim of this study was to study the cytohistological spectrum of palpable breast lesions and to evaluate the diagnostic accuracy of FNAC versus CNB for breast lesions.

MATERIALS AND METHODS

The study was a cross-sectional study conducted in the Department of Pathology and Surgery, over a period of 1 year in 152 patients. All the patients were subjected to FNAC and CNB. Cytosmears were stained with May-Grunwald Giemsa and hematoxylin and eosin was done on CNB and excision biopsy (EB) specimens. Sensitivity and specificity were calculated in percentage with 95% confidence interval with reference to CNB/surgical specimens. Kappa statistics were used to compare the level of agreement between FNAC versus CNB and CNB versus surgical specimens.

RESULTS

A total of 152 patients were taken for FNAC and CNB. EB was performed in only 104 patients. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of FNAC verses CNB in correlation with subsequent histopathology were found to be (93.40 vs. 94.06%), (97.50 vs. 100.00%), (99.00 vs. 100.00%), (84.78 vs. 33.33%), and (94.52 vs. 94.23%), respectively.

CONCLUSION

CNB has overcome the pitfall of FNAC but CNB cannot replace FNAC but both procedures are complementary to each other.

An audit of over 1000 breast cancer patients from a tertiary care center of Northern India

BACKGROUND

Breast cancer is the commonest cancer among women. India along with United States and China collectively account for one third of the global burden. The present study reports the clinico-epidemiological data of our patient population. This may help in better understanding of the disease in our population and also form ground for conducting further breast cancer research in India.

METHODS

The study was conducted at an apex teaching and medical research institution in India from September 2013 to April 2015 as a retrospective review of prospectively collected data of breast cancer patients. The socio-demographic characteristics, reproductive risk factors, clinical presentation, TNM staging and histopathological characteristics for breast cancer in these patients were recorded. The data was recorded on an Xcel spreadsheet and analyzed using IBM SPSS 21.

RESULTS

The study comprised of 1310 breast cancer patients with males comprising 1.1%. The median age of presentation was 47 years, and menarche 14 years. Most of women were married and multiparous. More than half of the women were postmenopausal at presentation. All patients were symptomatic at presentation with median duration of symptom of 5 months and median lump size of 5 cm. Most common stage at presentation was Stage II and most common histopathology was Invasive ductal carcinoma. 61.9% tumors were hormone receptor positive. Triple negative cancers formed one third of all tumors.

CONCLUSION

Breast cancer in the Indian scenario is a disease of younger woman who lack the characteristic reproductive and demographic risk factors. This calls for a need to study the clinico-demographic risk factors and characteristics of our own population.

Increasing breast cancer awareness and breast examination practices among women through health education and capacity building of primary healthcare providers: a pre-post intervention study in low socioeconomic area of Mumbai, India

OBJECTIVES

The present study aimed to improve breast cancer (BC) awareness and practices using Information, Education and Communication (IEC) modules and health educational sessions for women and primary healthcare providers in low socioeconomic community of Mumbai.

DESIGN

Pre-post quasi-experimental design.

SETTING

The study was conducted in a lower socioeconomic area of G-South ward of Mumbai, Maharashtra. The baseline and endline survey was conducted using structured interview schedules.

PARTICIPANTS

410 women were selected, aged between 18 and 55 years who were not pregnant, lactating or diagnosed with BC.

INTERVENTION

A health education-based intervention module was developed to educate women through group and individual sessions.

OUTCOMES

Summative indices were constructed to understand the net mean difference in knowledge of signs, symptoms and risk factors. Analysis of variance (ANOVA) and paired t-test were used to check the significant improvement of intervention.

RESULTS

Our results showed statistical significance in difference in mean knowledge scores for both signs and symptoms (mean difference (MD) 4.09, SD 4.05, p<0.00)) and risk factors of BC knowledge (MD 5.64, SD 4.00, p<0.00) among women after intervention. There was a marked improvement in the knowledge of BC among women with low education category. A significant improvement in knowledge of symptoms and risk factors among health workers was also observed. Our interventions resulted in positive change in breast examination practices. The breast self-examination (BSE) practices improved from around 3% to 65% and around 41% additional women went for clinical breast examination after intervention.

CONCLUSIONS

This study found a significant improvement in knowledge of BC signs and symptoms, risk factors and BSE practices among study participants following our health education interventions among these subpopulations. This evidence calls for inclusion of similar interventions through health education and capacity building of primary healthcare providers in national programmes.

Increasing Engagement for Breast Cancer Screening and Treatment: The "ICANTREAT" Community of Expertise Initiative

BACKGROUND

Incidence of breast cancer and associated mortality are on the rise globally. Breast cancer incidence in India is on the rise and also accounts for a staggering 50% mortality rate among women. Health illiteracy, socio-economic and cultural barriers in addition to lack of an organized nationwide screening and prevention programme contribute to poor patient outcomes. Thus, it is imperative to strengthen the existing screening and treatment facilities to address the increasing cancer burden. In this regard, we conducted a workshop to investigate the scope of a multi- stakeholder engagement in breast cancer screening and treatment.

METHODS

A stakeholder workshop grounded in an established co-design methodology  was convened in a semi-urban coastal district in South India with active participation of physicians, surgeons, occupational therapists, community leaders, programme officers, public health professionals and breast cancer survivors. Shiffman and Smith's framework was adapted to highlight barriers to screening and role of stakeholders in the co-design of solutions.

RESULTS

Deliberate and active discussions marked the workshop proceedings resulting in the identification of   individual and systems level barriers, facilitators and implementation strategies. Social stigma and non-existent standard protocols for screening and referral were recognised as critical barriers, while community engagement and a dedicated patient advocate were the proposed facilitators.

CONCLUSION

This workshop was an important step in bringing together key stakeholders and marked the beginning of the ICANTREAT initiative and a Community of Expertise. The outcomes highlight the importance of stakeholder involvement in the cancer- care pathway for breast cancer screening, diagnosis and treatment.

Impact of Educational Level and Family income on Breast Cancer Awareness among College-Going Girls in Shillong (Meghalaya), India

Background:

Breast cancer (BC) is the most common cancer among women in India and shows an increasing trend. The mammography screening seems unfeasible as a public health service in India. Thus, breast self-examination (BSE), followed by clinical breast examination (CBE), is the affordable method to downstage BC. A cross-sectional study was conducted with senior school and college-going girls in Shillong (Meghalaya) to study the impact of girls’ academic level and family income on breast cancer knowledge and the prevalence of BC’s known risk factors in girls.

Methods:

A self-administered questionnaire was employed to collect relevant information. The data were analysed using statistical software SPSS version 22. The categorical data presented as frequency (%) and the comparison made using Chi-square or Fisher exact test.

Results:

(i) 78.2% girls knew about breast cancer, 19.2% of these were aware of BSE, and 22.9% of BSE knowing ever performed it (ii) Awareness of breast cancer and BSE, and its practice is significantly associated with their academic level and family income (iii) The consumption of alcohol beverages and physical activity of girls was positively associated with educational level and family income (iv) Body mass index (BMI) was weakly associated with family income with an insignificant relationship with academic level (v) oily food consumption related inversely with the level of education irrespective of family income (vi) there was a positive correlation between parents education and family income.

Conclusions:

The results show a severe lack of breast cancer knowledge in senior school and college-going girls under the survey. To spread community awareness, we suggest a public health policy-driven educational intervention through culturally relevant mass/social media on the risk factors of breast cancer and practice of BSE. It is also recommended that dedicated facilities be created for breast cancer early diagnosis in the public health system.

'I don't talk about my distress to others; I feel that I have to suffer my problems...' Voices of Indian women with breast cancer: a qualitative interview study

Background

Breast cancer is the commonest form of cancer among women globally, including in India. The rising incidence in the developing world is thought to be due to increased life expectancy, urbanisation, and adoption of western lifestyles. A recent systematic review found that Indian women living in India or as immigrants in Canada experienced a range of psychological distresses both ameliorated and exacerbated by cultural issues personally, within the family, within their community, and in the context of faith, and only two of the five qualitative studies explored the experience of women with breast cancer living in India. Distress may also affect treatment compliance.

Aim

The aim of the study was to explore the psychological distresses experienced by Indian women with breast cancer living in Kerala, South India, during and after treatment and to understand better what helped to relieve or increase these distresses.

Methods

In-depth interviews were conducted with 20 consenting women undergoing treatment for breast cancer. Purposive sampling was used to obtain maximum variation in sociodemographic and clinical characteristics. Interviews were verbatim transcribed, translated into English, and back-translated to Malayalam to ensure that the meaning had not been lost. English data were analysed using thematic frame work analysis and synthesised to provide a deeper understanding of the individuals’ experience.

Results

Three major themes emerged from the data. The first major theme was ‘far-reaching psychological distress’. This included anxiety, guilt, anger, and depression in response to the disease and physical side effects of treatment and issues relating to body image, especially hair loss and sexuality. The second major theme was ‘getting on with life’. Women tried to make sense of the disease, by actively seeking information, the role of medical professionals, and their practical adaptations. Many found a new future and a new way to live normal. The third major theme was the ‘support system’ strongly based on family, friends, faith, and the community which affect them positively as well as negatively.

Conclusion

Psychological concerns related to disease and treatment are common in Indian women with particular emphasis on body image issues associated with hair loss. Family and faith were key support systems for almost all the women, although it could also be the causes of distress.

Breast cancer in Andaman and Nicobar Islands: A retrospective analysis

Background

Breast cancer is the most common cancer in India among women. This study was conducted to describe the demographic, clinical, histopathological, endocrinological and survival pattern of breast cancer patients in Andaman and Nicobar Islands.

Methods

The study was done in Medical Oncology department of GB pant hospital. Data was retrieved from the case sheets of patients who consulted from 1st February 2015 to 31st January 2018. As this hospital is the only referral hospital, the patients are representative of all cancer patients in the Island, and the population base is well defined.

Results

During the study period, 85 breast cancer patients were treated. Of the 82 female patients, the standardized incidence rates in 2015, 2016 and 2017 were 8.82, 13 and 14.42 per 100,000 women respectively. The prevalence and mortality rates in 2015, 2016, 2017 were 14.88, 27.96, 40.37, and 1.1, 2.74, 0.55 per 100,000 women respectively. Metastasis was detected at the time of diagnosis in 18.8% of patients. Estrogen receptor (ER) and progesterone receptor (PR) positivity was reported in 55.9% of patients, HER 2 positivity in 28.1% and triple negativity in 27.3%. The overall survival at 12, 24, and 36 months follow-up were 88.9%, 84.3% and 52.7% respectively. In univariable analysis, the hazard ratios were significantly higher for patients with metastasis and diagnosis before 2015.

Conclusion

As compared to the country, breast cancer incidence was lower in the Islands with better survival. Stage at diagnosis was the most important factor determining survival in these patients.

Knowledge of symptoms and risk factors of breast cancer among women: a community based study in a low socio-economic area of Mumbai, India

Background

Breast cancer (BC) is leading cancer among women in India accounting for 27% of all cancers among women. Factors that make the policymakers and public health system worried are rising incidence of breast cancer in India and more importantly high death rates among breast cancer patients. One of the leading causes of high breast cancer deaths is lack of awareness and screening leading to the late presentation at an advanced stage. Therefore, the current research aimed to understand the knowledge of breast cancer symptoms and risk factors among women in a low socio-economic area of Mumbai.

Methods

A cross-sectional study was conducted at Prabhadevi, Mumbai and primary data was collected from 480 women aged 18–55 years. Structured questionnaire was used to collect quantitative data pertaining to awareness, signs and symptoms of breast cancer. Bivariate and multivariate regression techniques were used for understanding of the socio-demographic differentials in breast cancer awareness among women.

Results

The study found that around half (49%) of the women were aware of breast cancer. The women who were aware of breast cancer considered lump in breast (75%), change in shape and size of breast (57%), lump under armpit (56%), pain in one breast (56%) as the important and common symptoms. Less than one-fifth of the women who were aware of breast cancer reported early menstruation (5.6%), late menopause (10%), hormone therapy (13%), late pregnancy (15%) and obesity (19%) as the risk factors for breast cancer. The multivariate regression analysis showed women who had more than 10 years of schooling (Adjusted Odds Ratio: 3.93, CI: 2.57–6.02, P < 0.01) were about 4 times more likely to be aware of breast cancer than women who had less than 10 years of schooling.

Conclusion

In conclusion, knowledge of danger signs and risk factors of breast cancer were low among women in the community. This may lead to late detection of breast cancer among women in the community. Therefore, the study calls for advocacy and larger intervention to enhance knowledge of breast cancer among women in the particular region with a special reference to women with low education.

A Theory-Based and Culturally Aligned Training Program on Breast and Cervical Cancer Prevention for South Asian Community Health Workers: A Feasibility Study

BACKGROUND

Cancer screening uptake among South Asian ethnic minorities is reported to be relatively low. An outreach program, led by community health workers (CHWs), may increase the minority group's awareness of the importance of cancer screening.

OBJECTIVE

The aim of this study was to assess the feasibility and effectiveness of a theory-based, culturally sensitive program to train South Asian women in Hong Kong as CHWs.

METHODS

A CHW training program, guided by the Empowerment Model and the Health Belief Model, was developed and implemented. Its feasibility was evaluated through the recruitment of South Asian women to the program and their satisfaction with it. Its effectiveness was assessed by a test of knowledge, the participants' self-efficacy and competence, and their readiness to work as CHWs.

RESULTS

Five South Asian women were recruited to the training program. Outcomes included increased participants' knowledge of cancer and improved self-efficacy and competence in working as CHWs. All participants were highly satisfied with the program, although the addition of practical sessions in the South Asian community was suggested as a further improvement.

CONCLUSION

It seems to be feasible to train South Asian CHWs to deliver interventions to promote their peers' awareness of breast and cervical cancer prevention, although challenges exist in recruitment of trainees. More hands-on practical opportunities as CHWs would likely increase their effectiveness.

IMPLICATIONS FOR PRACTICE

The theoretical framework of our CHW training program and the incorporated cultural components could be useful for the development of future programs for training South Asian CHWs in delivering interventions on cancer prevention.

Exploring perceptions and practices of cancer care among caregivers and care recipients of breast cancer in India

OBJECTIVE

Cancer care is physically and psychologically challenging for both care recipients and caregivers. Caregiving in cancer is an area that needs urgent attention in India. Much of caregiving literature in India is limited to mental illnesses. This study thus examines the perceptions and practices of psychological caregiving among caregivers and care recipients of breast cancer in India.

METHODS

Participants were interviewed with the aid of a semistructured qualitative interview guide. Participants included 39 caregivers and 35 care recipients in different breast cancer stages. Interviews were transcribed, translated to English, and coded, and themes were derived for further analysis. Informed consent from participants and ethical clearance and permission from a tertiary hospital were obtained prior to data collection.

RESULTS

Psychological caregiving as perceived by the participants included actions such as encouraging, convincing care recipients, companionship, and maintaining a stress-free environment. Caregivers in particular felt that psychological caregiving meant reacting calmly to sensitive queries of nonfamily members, providing emotional support to other family members, and involvement in religious activities. Taking on such diverse responsibilities gave rise to several unmet psychological needs such as motivation and support in decision making from other family members.

CONCLUSIONS

Irrespective of the status (caregiver or care recipient), participants in this study felt the need for structured counselling services to be incorporated into the standard care protocol. This is an area that needs to be further explored in the context of the breast cancer caregiver and care recipient dyad.

Application of the Champion Health Belief Model to determine beliefs and behaviors of Turkish women academicians regarding breast cancer screening: A cross sectional descriptive study

BACKGROUND

Breast cancer is an important cancer type and the most common malignancy among women in both developed and developing countries and the second leading cause of cancer death in women worldwide. This study aimed to examine the projected risk of breast cancer in Turkish women academician, determine the levels of their breast cancer screening behaviors and uncover the relationship between their health beliefs and screening behaviors.

METHODS

This cross-sectional descriptive study was conducted from March to July 2018 in the province of Aydın, Turkey with a total of 200 female academicians. The data were collected using questionnaires filled out by the participants and the Turkish version of the Champion Health Belief Model Scale. Data were analyzed using t test, ANOVA, Chi-square and logistic regression performed with Statistical Package for Social Sciences version 20.

RESULTS

The mean age of the female academics was 36.1 ± 0.53 years. The female performing breast self-examination had higher perceived sensitivity (OR = 2.88, 95% Cl 1.32, 2.66) benefits to breast self-examination (OR = 0.90, 95% Cl 0.82, 0.99), self-efficacy (OR = 0.87, 95% Cl 0.81, 0.93) health motivation (OR = 1.74, 95% Cl 0.50, 0.90), benefit to mammography (OR = 0.97, 95% Cl 0.88, 1.08), lower barrier to mammography (OR = 1.05, 95% Cl 1.0, 1.09) than women who did not. Female academics with clinical breast examination had higher self-efficacy (OR = 0.91, 95% Cl 0.86, 0.97) and lower barrier to mammography (OR = 1.06, 95% Cl 1.02, 1.10) than women who did not. The female with take mammography had higher sensitivity (OR = 0.84, 95% Cl 0.72, 0.98), lower barrier to breast self-examination (OR = 1.08, 95% Cl 1.02, 1.15) and lower barrier to mammography (OR = 1.09, 95% Cl 1.04, 1.14) than female who did not.

CONCLUSIONS

Female academicians in Turkey exhibit positive attitudes towards breast self-examination, clinical breast examination and mammography as they have higher perceived sensitivity against breast cancer, self-efficacy and fewer barriers. Long-term community-based programs should be extended to different groups of women from a variety of socio-demographic environments.

Outcomes of Breast Cancer Management from an Urban Specialist Breast Center in South India

Context and Aims: The disease pattern and presentation of breast cancer in India are thought to differ from the West. The purpose of this study is to describe and to discuss the presentation, clinicopathological data, and survival from an urban specialist breast center in Southern India. Materials and Methods: Prospectively collected data were analyzed for clinicopathological details, treatment variables, and survival outcomes were analyzed. Cumulative survival curves were estimated using the Kaplan–Meier method for patients treated from 2007 to 2011. Results: A total of 1671 patients were operated at our center from January 2007 to December 2016. Average age at diagnosis was 54.2 years. Over 70% had Stage I and Stage II disease, infiltrating duct carcinoma was predominant in 88.2%. Average clinical tumor size was three centimeters. Breast conservation was performed in 22.4%. Sentinel lymph node biopsy was performed in 44.6%. Estrogen-receptor positivity was seen in 64.6%, 22.2% were Her2Neu positive. Triple negative disease was seen in 19.1%. Survival analysis was done using the Kaplan–Meier curves for 540 patients treated from 2007 to 2011. The median follow-up of surviving patients was 70 months with 10% lost to follow-up. In our study population, the 5 years overall survival rate is 88.3% and disease-free survival is 85.7%. Conclusion: Our study reflects a higher percentage of early breast cancer with outcomes comparable to the West. More research is required to understand the genetic predisposition in our population.

Structure Guided Molecular Docking Assisted Alignment Dependent 3DQSAR Study on Steroidal Aromatase Inhibitors (SAIs) as Anti-breast Cancer Agents

Background:

In spite of the availability of various treatment approaches including surgery, radiotherapy, and hormonal therapy, the steroidal aromatase inhibitors (SAIs) play a significant role as chemotherapeutic agents for the treatment of estrogen-dependent breast cancer with the benefit of reduced risk of recurrence. However, due to greater toxicity and side effects associated with currently available anti-breast cancer agents, there is emergent requirement to develop target-specific AIs with safer anti-breast cancer profile.

Methods:

It is challenging task to design target-specific and less toxic SAIs, though the molecular modeling tools viz. molecular docking simulations and QSAR have been continuing for more than two decades for the fast and efficient designing of novel, selective, potent and safe molecules against various biological targets to fight the number of dreaded diseases/disorders. In order to design novel and selective SAIs, structure guided molecular docking assisted alignment dependent 3D-QSAR studies was performed on a data set comprises of 22 molecules bearing steroidal scaffold with wide range of aromatase inhibitory activity.

Results:

3D-QSAR model developed using molecular weighted (MW) extent alignment approach showed good statistical quality and predictive ability when compared to model developed using moments of inertia (MI) alignment approach.

Conclusion:

The explored binding interactions and generated pharmacophoric features (steric and electrostatic) of steroidal molecules could be exploited for further design, direct synthesis and development of new potential safer SAIs, that can be effective to reduce the mortality and morbidity associated with breast cancer.

Breast Cancer knowledge, perceptions and practices in a rural Community in Coastal Kenya

Background

Data on breast healthcare knowledge, perceptions and practice among women in rural Kenya is limited. Furthermore, the role of the male head of household in influencing a woman’s breast health seeking behavior is also not known. The aim of this study was to assess the knowledge, perceptions and practice of breast cancer among women, male heads of households, opinion leaders and healthcare providers within a rural community in Kenya. Our secondary objective was to explore the role of male heads of households in influencing a woman’s breast health seeking behavior.

Methods

This was a mixed method cross-sectional study, conducted between Sept 1st 2015 Sept 30th 2016. We administered surveys to women and male heads of households. Outcomes of interest were analysed in Stata ver 13 and tabulated against gender. We conducted six focus group discussions (FGDs) and 22 key informant interviews (KIIs) with opinion leaders and health care providers, respectively. Elements of the Rapid Assessment Process (RAP) were used to guide analysis of the FGDs and the KIIs.

Results

A total of 442 women and 237 male heads of households participated in the survey. Although more than 80% of respondents had heard of breast cancer, fewer than 10% of women and male heads of households had knowledge of 2 or more of its risk factors.

More than 85% of both men and women perceived breast cancer as a very serious illness. Over 90% of respondents would visit a health facility for a breast lump.

Variable recognition of signs of breast cancer, limited decision- autonomy for women, a preference for traditional healers, lack of trust in the health care system, inadequate access to services, limited early-detection services were the six themes that emerged from the FGDs and the KIIs. There were discrepancies between the qualitative and quantitative data for the perceived role of the male head of household as a barrier to seeking breast health care.

Conclusions

Determining level of breast cancer knowledge, the characteristics of breast health seeking behavior and the perceived barriers to accessing breast health are the first steps in establishing locally relevant intervention programs.

Molecular Mechanism of Cancer Susceptibility Associated with Fok1 Single Nucleotide Polymorphism of VDR in Relation to Breast Cancer

Breast cancer is the leading cause of death among women worldwide. It is a multi-factorial disease caused by genetic and environmental factors. Vitamin D has been hypothesized to lower the risk of breast cancer via the nuclear vitamin D receptor (VDR). Genetic variants of these vitamin D metabolizing genes may alter the bioavailability of vitamin D, and hence modulate the risk of breast cancer.

Rate of Breast-Conserving Surgery vs Mastectomy in Breast Cancer: a Tertiary Care Centre Experience from South India

Worldwide, breast conservation has become increasingly accepted as the surgical management of breast cancer in clinical practice. Cancer care in India is also evolving tremendously with many cancer treatment centres following evidence-based practice hence the rates of breast conservation are expected to increase. Here, we are reporting the rate of breast-conserving surgery (BCS) at our centre. A retrospective study of 401 patients who underwent breast cancer surgery at a tertiary care centre in South India from January 2015 to August 2017 were analysed to study the rate of BCS. All early breast cancers (EBC) were offered BCS. For large operable breast cancer (LOBC) and locally advanced breast cancer (LABC), neoadjuvant chemotherapy (NACT) followed by BCS was offered to these patients who wish to conserve their breast. The mean age was 45 years. A total of 163 patients underwent BCS. Yearly, BCS rates were 38.8% in 2015, 36.7% in 2016 and 46.5% in 2017. Majority had EBC 310 (77.3%) of which 62.7% of T1 lesions (n = 51) had BCS, and 45.7% of T2 lesions (n = 258) had BCS of which 5 patients had to undergo NACT to preserve their breast whereas 100% Tis patient (n = 1) had mastectomy. Fifty patients had LOBC and only 2 (4%) patients had upfront BCS whereas 9 of them had to undergo NACT (18%). cT4 lesions had NACT followed by BCS in 2 patients. The rates of BCS have been increasing in India over the past few years. The majority of the women presented with EBC which makes them suitable for BCS.

Patterns of Care of Breast Cancer Patients in a Rural Cancer Center in Western India

Breast cancer is an emerging public health problem in low- and middle-income countries. The main objective is to describe the clinical characteristics and patterns of care of breast cancer patients diagnosed and treated in a rural cancer hospital in Barshi, Western India. The results from a cross-sectional study of 99 consecutive breast cancer patients diagnosed and treated between February 2012 and November 2014 in Nargis Dutt Memorial Cancer Hospital is reported. The case records of the patients were scrutinized and reviewed to abstract data on their clinical characteristics, diagnostic, and treatment details. The mean age at diagnosis of the patients was 52.8 ± 11.6 years; 83.5% of women were married, and 60.6% were illiterate. Sixty percent of patients had tumors measuring 5 cm or less. Almost half of the patients (46.4%) had stage I or II A disease and a third (36.0%) had axillary lymph node metastasis. Estrogen, progesterone, and human epidermal growth factor receptor2 receptor status were investigated in 41 (41.4%) of patients only. The median interval between diagnosis and initiation of treatment was 11 days. Modified radical mastectomy was done in 91% of patients, and nearly a third of patients who were prescribed chemotherapy did not complete treatment. The rural-based tertiary cancer care center has made treatment more accessible to breast cancer patients and has reduced the interval between diagnosis and treatment initiation. However, there are still many challenges like non-compliance to and incomplete treatments and poor follow-up that need to be addressed.

Incidence trends and patterns of breast cancer in Sri Lanka: an analysis of the national cancer database

BACKGROUND

A gradual decline in the incidence of breast cancer is documented in developed countries especially over last two decades, while in developing countries the incidence continues to rise. We conducted this study to examine trends in incidence of breast cancer in a developing country, Sri Lanka.

METHODS

A retrospective cohort evaluation of patients with breast cancer during 2001-2010 was performed using population based data from the Sri Lanka National Cancer Registry. Trends in incidence were analysed using Joinpoint regression analysis.

RESULTS

The age standardized incidence of female breast cancer in Sri Lanka appears to have increased from 17.3 per 100,000 in 2001 (95% confidence interval [95% CI] 16.5-18.2) to 24.7 per 100,000 in 2010 (95% CI 23.7-25.7); a 1.4-fold increase (p < 0.05) with an estimated annual percentage change (EAPC) of 4.4 (95% CI 3.3-5.5). Highest incidence of breast cancer was seen among women of 60 to 64-year age group which has increased from 68.1 to 100.2 per 100,000 over this period (EAPC 4.6%, 95% CI 3.9-5.2, p < 0.001 for trend). A substantially greater increase was observed among women older than 50 years (from 50.4 to 76.9 per 100,000; EAPC 5.5, 95% CI 4.1-7.0, p < 0.05) compared with women younger than 50 years (from 32.0 to 39.6 per 100,000; EAPC 2.3, 95% CI 1.1-3.5, p < 0.05).

CONCLUSIONS

A gradual but a significant increase in the incidence of female breast cancer is observed in Sri Lanka. A rapid rise in the breast cancer incidence among post-menopausal women appears to be the major contributor towards this increase. Improving cancer data collection appears to have been a contributor to the observed increase. However, an inherent increase is also likely as differential rates of increase were observed by age groups. Further research is needed to identify the reasons for the observed increase which may help with future cancer control efforts in Sri Lanka.

Attitude and Practice Regarding Breast Cancer Early Detection among Iranian Women: A Systematic Review

Objectives: To determining attitudes and practice regarding breast cancer early detection techniques (breast self-examination (BSE), clinical breast examination (CBE) and mammography) among Iranian woman. Methods: International (PubMed, ISI, and Google Scholar) and national (SID and Magiran) databases were reviewed up to September 2017 to identify articles related to the attitudes and practices of Iranian women concerning breast cancer screening behavior with reference to BSE , CBE and mammography. The screening steps, analysis of quality of the studies and extraction of the papers were performed by two reviewers. Results: Of the 532 studies included initially, 21 performed on 10,521 people were considered eligible. Subjects with a positive attitude toward BSE in various studies were 13.5% to 94.0% with an average of 47.6%. Positive attitudes to CBE and mammography were found in 21.0% and 26.4%, respectively. Participant performance of BSE ranged from 2.6% to 84.7%, with an average of 21.9%. The respective figures for CBE and mammography were 15.8% and 16.7%. Conclusion: Considering the poor performance and low rates for positive attitudes, it is suggested that educational programs should be conducted across the country.

Evidence for overuse of medical services around the world

Overuse, which is defined as the provision of medical services that are more likely to cause harm than good, is a pervasive problem. Direct measurement of overuse through documentation of delivery of inappropriate services is challenging given the difficulty of defining appropriate care for patients with individual preferences and needs; overuse can also be measured indirectly through examination of unwarranted geographical variations in prevalence of procedures and care intensity. Despite the challenges, the high prevalence of overuse is well documented in high-income countries across a wide range of services and is increasingly recognised in low-income countries. Overuse of unneeded services can harm patients physically and psychologically, and can harm health systems by wasting resources and deflecting investments in both public health and social spending, which is known to contribute to health. Although harms from overuse have not been well quantified and trends have not been well described, overuse is likely to be increasing worldwide.

Breast Biomarkers-Comparison on Whole Section and Tissue Microarray Section

INTRODUCTION

Estrogen Receptor (ER), Progesterone Receptor (PR) and Her2/neu are routinely studied markers for breast carcinoma. Analysis of these biomarkers is traditionally done by Immunohistochemistry (IHC) on whole sections. These markers can also be studied on Tissue Microarray (TMA) sections. Tissue microarray is a technique where core samples from different paraffin blocks are arrayed on a single recipient block which can then be cut to yield a single section with multiple cores in it.

AIM

To compare ER, PR and Her2/neu on TMA sections with whole sections and to determine the concordance of results between the two methods.

MATERIALS AND METHODS

A TMA block was constructed by punching out 2 mm cores from appropriately marked paraffin blocks of 53 breast carcinoma cases and embedding them in the recipient block. Immunostaining of TMA sections and whole sections were performed for ER, PR and Her2/neu and the results were compared. Statistical analysis was done using chi square test/Fisher-Exact test. Kappa co-efficient, Jaccard Index and G-Index were computed.

RESULTS

Infiltrating Ductal Carcinoma-No Special Type (IDC-NST) was the predominant type of carcinoma and most of the tumours were of Grade II and III. Majority, 38/53 (71.7%) were ER/PR positive and Her2 negative and 9/53 (17%) cases were triple negative. Good concordance between whole sections and TMA sections were noted with kappa value for ER, PR and Her2/neu being 0.671, 0.754, 1.000 respectively which was statistically significant.

CONCLUSION

Immunostaining for ER, PR and Her2/neu done on TMA section using single 2 mm core were comparable with conventional whole section scores. Thus, TMA is a reliable method for evaluating these biomarkers with the advantage of being time and cost effective.

Effect of lymphangiogenesis and lymphovascular invasion on the survival pattern of breast cancer patients

BACKGROUND

Invasion of breast cancer cells into blood and lymphatic vessels is one of the most important steps for metastasis. In this study the prognostic relevance of lymphangiogenesis and lymphovascular invasion (LVI) in breast cancer patients was evaluated in terms of survival.

MATERIALS AND METHODS

This retrospective study concerned 518 breast cancer patients who were treated at Department of Surgical Oncology, Saroj Gupta Cancer Centre and Research Institute, Kolkata-700063, West Bengal, India, a reputed cancer centre and research institute of eastern India between January 2006 and December 2007.

RESULTS

The median overall survival and disease free survival of the patients were 60 months and 54 months respectively. As per Log-rank test, poor overall as well as disease free survival pattern was observed for LVI positive patients as compared with LVI negative patients (p<0.01). Also poor overall as well as disease free survival pattern was observed for perineural invasion (PNI) positive patients as compared to PNI negative patients (p<0.01).

CONCLUSIONS

From this study it is evident that LVI and PNI are strongly associated with outcome in terms of disease free as well as overall survival in breast cancer patients. Thus LVI and PNI constitute potential targets for treatment of breast cancer patients. We advocate incorporating their status into breast cancer staging systems.

Breast cancer: An overview of published Indian data

The Incidence of breast cancer has been steadily increasing in the last two decades, more so in urban areas of the sub-continent. Cancer ceters across the country have large numbers of patients being treated with multiple publications in this field. Inspite of paucity of prospective data and randomised clinical trials from India, there are large number of retrospective publications on various aspects of the disease including pathology, radiology, surgery, chemotherapy, radiation, palliative care and alternatitive treatment modalities. These published data provide an insight into the trends of breast cancer in the country and this comprehensive data review of Indian data will provide a basis for designing trials relevant to our population and planning health care.

Prevalence of Triple-Negative Breast Cancer in India: Systematic Review and Meta-Analysis

Purpose

There is considerable variation in prevalence rates of triple-negative breast cancer (TNBC) reported by various studies from India. We performed a systematic review and literature-based meta-analysis of these studies.

Methods

We searched databases of Medline, Scopus, EMBASE, and Web of Science for studies that reported on the prevalence of TNBC in India that were published between January 1, 1999, and December 31, 2015. We extracted relevant information from each study by using a standardized form. We pooled study-specific estimates by using random-effects meta-analysis to provide summary estimates. We explored sources of heterogeneity by using subgroup analyses and metaregression.

Results

Data were obtained from 17 studies that involved 7,237 patients with breast cancer. Overall combined prevalence of TNBC was 31% (95% CI, 27% to 35%). There was substantial heterogeneity across the studies (I² of 91% [95% CI, 88% to 94%]; P < .001) that was not explained by available study level characteristics, including study location, definition of human epidermal growth factor receptor 2 or estrogen receptor, mean age of participants, proportion of patients with premenopausal cancer, grade 3 disease, or tumor size > 5 cm. Overall combined prevalence of hormone receptor–positive and human epidermal growth factor receptor 2–positive breast cancer was 48% (95% CI, 42% to 54%) and 27% (95% CI, 24% to 31%), respectively. There was no evidence of publication bias.

Conclusion

Prevalence of TNBC in India is considerably higher compared with that seen in Western populations. As many as as one in three women with breast cancer could have triple-negative disease. This finding has significant clinical relevance as it may contribute to poor outcomes in patients with breast cancer in India. Additional research is needed to understand the determinants of TNBC in India.

Breast cancer knowledge, attitudes and screening behaviors among Indian-Australian women

PURPOSE OF RESEARCH

The aims of the study were to report breast cancer screening practices among Indian-Australian women and to examine the relationship between demographic characteristics, cultural beliefs and women's breast cancer screening (BCS) behaviors.

METHOD

A descriptive and cross-sectional method was used. Two hundred and forty two Indian-Australian women were recruited from several Indian organizations. English versions of the Breast Cancer Screening Beliefs Questionnaire (BCSBQ) were administered. The main research variables are BCS practices, demographic characteristics and total scores on each of the BCSBQ subscales.

RESULT

The majority of participants (72.7%-81.4%) had heard of breast awareness, clinical breast examination (CBE) and mammograms. Only 28.9% performed a BSE monthly and although 60% had practiced CBE, only 27.3% of women within the targeted age group had annual CBE. Only 23.6% of women within the targeted age group reported they had a mammogram biennial. Marital status and length of stay in Australia were positively associated with women's screening behaviors. In terms of BCSBQ score, women who had the three screening practices regularly as recommended obtained significantly higher scores on the "attitude towards general health check-ups" and "barriers to mammographic screening" subscales. There was a significant difference in the mean score of the "knowledge and perceptions about breast cancer" between women who did and who did not engage in breast awareness.

CONCLUSIONS

Our study reveals that attitudes toward health check-ups and perceived barriers to mammographic screening were influential in determining compliance with breast cancer screening practices among Indian-Australian women.

Descriptive study on selected risk factors and histopathology of breast carcinoma in a tertiary care centre in Kerala, India with special reference to women under 40 years old

BACKGROUND

Breast cancer is the most common female cancer in Kerala, South India, with the incidence increasing in the past two decades, also in young women. However, there are limited data regarding the burden of disease, its epidemiology and histopathological characteristics in the state.

MATERIALS AND METHODS

This desciptive study covered 303 breast cancers evaluated during the period of December 2011 to August 2013 in the Department of Pathology, Government Medical College, Kottayam.The patients were also interviewed regarding selected risk factors.

RESULTS

The majority of the cases were 41-60 years of age with a mean at presentation of 53 years. Infiltrating ductal carcinoma was the most common subtype, followed by pure mucinous carcinoma and then lobular carcinoma. Of the cases, 6.6% were nullipara and 52.8% had fewer than or equal to 2 children. Median age at first child birth was 23 years (national value-19.8 years). A significant proportion (15%) had family history of breast cancer. Some 13.5%(41 cases) comprised the young breast cancer group (≤40years) with a mean age at first child birth in them was 27.4 years, 5 being nullipara and 6 having a positive family history.

CONCLUSIONS

Breast cancer awareness, better availability of screening techniques and identification and targeting high risk groups all help to tackle the increasing load of breast carcinoma. A good proportion of cases comprised the young breast cancer group (under 40). Younger women should thus also be educated about breast carcinoma-risk factors, symptoms and diagnostic techniques to help in early detection and effective approach esto treatment.

Development of nanotheranostics against metastatic breast cancer--A focus on the biology & mechanistic approaches

Treatment for metastatic breast cancer still remains to be a challenge since the currently available diagnostic and treatment strategies fail to detect the micro-metastasis resulting in higher mortality rate. Moreover, the lack of specificity to target circulating tumor cells is also a factor. In addition, currently available imaging modalities to identify the secondaries vary with respect to various metastatic anatomic areas and size of the tumor. The drawbacks associated with the existing clinical management of the metastatic breast cancer demands the requirement of multifunctional nanotheranostics, which could diagnose at macro- and microscopic level, target the solid as well as circulating tumor cells and control further progression with the simultaneous evaluation of treatment response in a single platform. However, without the understanding of the biology as well as preferential homing ability of circulating tumor cells at distant organs, it is quite impossible to address the existing challenges in the present diagnostics and therapeutics against the breast cancer metastasis. Hence this review outlines the severity of the problem, basic biology and organ specificity with the sequential steps for the secondary progression of disease followed by the various mechanistic approaches in diagnosis and therapy at different stages.

Effect of complete decongestive therapy and a home program for patients with post mastectomy lymphedema

[Purpose] Post mastectomy lymphedema is common among breast cancer survivors. It leads to physical discomfort and functional impairment. Rehabilitation forms the mainstay of treatment and is multidisciplinary. [Subjects and Methods] Sixty post mastectomy patients were allocated randomly and assigned to either a conventional treatment group (n=30) or a complete decongestive therapy (CDT) group (n=30). The conventional treatment group received manual lymphatic drainage, wore a low elastic compression garment, received glenohumeral mobilization, and performed deep breathing exercises, and the complete decongestive therapy group received CDT from a trained physiotherapist and a daily home program along with the conventional treatment, 5 days a week for 6 weeks. [Results] Arm circumference measurements were taken at five levels: the wrist, mid forearm, elbow, mid-upper arm, and axilla. The upper extremity function was evaluated using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and pain was assessed using the visual analogue scale. Measurements were taken at baseline, and at 4th and 6th weeks after the start of intervention. Within and between group comparisons showed significant improvements in the CDT group. [Conclusion] Complete decongestive therapy and a home program assists breast cancer related lymphedema survivors in regaining their lost functions. It also helps to improve their independence in daily activities, reduce their need for caregivers, and thereby improving their quality of life. Therefore, the results of this study showed that the CDT with a home program is an effective treatment for reducing post mastectomy lymphedema.

Interrelationships Between Ki67, HER2/neu, p53, ER, and PR Status and Their Associations With Tumor Grade and Lymph Node Involvement in Breast Carcinoma Subtypes: Retrospective-Observational Analytical Study

Various predictive and prognostic factors could affect breast carcinoma behavior, but to date no definitive correlation has been established between them and breast carcinoma subtypes. The present study was conducted to examine the interrelationships of these predictive and prognostic factors as well as their effects on breast carcinoma subtypes.The archives of all patients with breast carcinoma (from 2008 to 2014) were studied. Patients' data were extracted using a checklist that included age, histology type, size and grade of tumor, lymph node involvement, estrogen receptor (ER) and progesterone receptor (PR) status, along with the overexpression of human epidermal growth factor receptor (HER2/neu) and the rate of Ki67 and p53 mutations. All data were analyzed by SPSS-17 software with χ and Fisher exact tests, as well as the least significant difference pairwise comparison test.A total of 566 patients' records were included in this study. The mean age of patients was 50 ± 12.9 with an age range of 17 to 98 years. A meaningful correlation was found between age and the type of tumor (P = 0.001). Infiltrating lobular carcinoma had a higher ER positivity between groups (85.7%), whereas noninvasive carcinomas had a higher PR positivity (67%). In addition, a meaningful correlation was detected between the type and grade of tumor (P = 0.001). No meaningful relationship was observed between the type of tumor and HER2/neu overexpression and number of lymph nodes involved. Between the groups, medullary carcinoma had the highest Ki67 index (P = 0.007). Meaningful correlation was found between the grade of tumor and lymph node involvement (P = 0.005) and also with HER2/neu overexpression (P = 0.002). Higher grades had greater positivity in Ki67 index and p53 mutation rates (P = 0.002, P = 0.01). HER2/neu positive tumors had a higher Ki67 index (P = 0.03).Higher Ki67 index tumors showed more HER2/neu overexpression, larger size, and more lymph node involvement compared with other types and maybe considered aggressive. Moreover, in young patients with breast carcinoma, the rates of Ki67 with the overexpression of HER2/neu and p53 mutations are higher, and it shows a more aggressive behavior than other tumors assessed in this age group.

Recommendations for screening and early detection of common cancers in India

Cancers of the breast, uterine cervix, and lip or oral cavity are three of the most common malignancies in India. Together, they account for about 34% of more than 1 million individuals diagnosed with cancer in India each year. At each of these cancer sites, tumours are detectable at early stages when they are most likely to be cured with standard treatment protocols. Recognising the key role that effective early detection and screening programmes could have in reducing the cancer burden, the Indian Institute for Cytology and Preventive Oncology, in collaboration with the US National Cancer Institute Center for Global Health, held a workshop to summarise feasible options and relevant evidence for screening and early detection of common cancers in India. The evidence-based recommendations provided in this Review are intended to act as a guide for policy makers, clinicians, and public health practitioners who are developing and implementing strategies in cancer control for the three most common cancers in India.
