Abstract:

Background: Human papillomavirus (HPV) infection plays key role in the development of cervical cancer. The prevalence of HPV infection is increasing in China, but the socioeconomic and lifestyle factors associated with HPV infection in pregnant Chinese women have not been systematically analyzed. The purpose of this study is to investigate the relationship between socioeconomic/lifestyle factors and HPV infection among pregnant Chinese women in Beijing. The study hypotheses are: (1) when compared to pregnant women without HPV, pregnant women with HPV infection are more likely to be in the lower socioeconomic status (SES) as measured by education, occupation and household income; (2) when compared to pregnant women without HPV, pregnant women with HPV infection are more likely to choose unhealthy lifestyles as measured by tobacco smoking, alcohol consumption, and physical inactivity. Methods: In this age matched case-control study, we examined the effect of socioeconomic and lifestyle factors on 66 pregnant women (HPV positive) and 132 pregnant women (HPV negative) in two hospitals in Beijing. Results: Our data suggest that alcohol consumption during pregnancy is the strongest significant factor associated with HPV infection in Chinese women. There were no statistical differences observed in any of the socioeconomic factors when comparing the HPV positive and negative groups. Conclusion: Public health strategies that focus on regulation of the sales and consumption of alcohol in China, and development of health education programs for pregnant women, would be positive steps to approach solutions to this problem.

Abstract:

Introduction: Breast cancer is a major cause of death among women all over the world.  Alpha-1 antitrypsin (A1AT) is a glycoprotein and an inhibitor of serine proteases (1). Binding of A1AT with polyunsaturated fatty acids like Alpha linolenic acid and oleic acid was recently reported (2).  Delta 9 desaturase (D9D), D5D and D6D catalyse the rate limiting steps in the fatty acids conversion. Our aim was to find an association between Alpha-1 antitrypsin levels and delta desaturases activity among breast cancer women and control women.

Materials and methods: 40 breast cancer women and 20 control women were analysed for fatty acids by gas chromatography and alpha 1 antitrypsin by immunoturbidimetric method.

Results:  Breast cancer women had A1AT levels between 106-240mg/dl whereas the A1AT levels in control women were between 98-180mg/dl. D5D and D9D-18 activities were significantly higher in cancer cases than in the control subject (P=0.001). No statistical  significant correlation was observed in both the groups . But there was negative correlation between A1AT and D9D activity in both the groups.

Discussion: Our data indicate that D5D and D9D activities were higher in the breast cancer women. The underlying mechanism could be the competition between n-3 and n-6 long chain fatty acids for eicosanoid production. To our knowledge it is the first time to show the association of delta desaturase activity and A1AT in breast cancer women and control women. Variation in the A1AT and delta desaturases may provide new insights for diagnostic and therapeutic strategies for breast  cancer women and help women from cancer.

Biography:

Introduction: Breast cancer is the second most leading cause of death in women. It is an important health issue not only in the developed world but also in resource limited nation. Incidence of breast cancers low in India compared to Western countries, but it is associated with poor prognosis and high mortality, may be due to late presentation at advanced stages. Hormone receptors (estrogen and progesterone) and Human epidermal growth factor receptor-2 (HER-2) study are not routinely carried out as it is expensive, especially in developing countries. This could impact treatment decisions and patients are sometimes treated empirically with tamoxifen. Triple-negative breast cancers are group of primary breast cancers which lack expression for hormone receptors and Human epidermal growth factor receptor-2.

Objectives: This study is aimed to pathologically illustrate morphological prognostic parameters in primary invasive breast carcinoma and triple negative breast cancer. Further, to analyze the association between clinicopathological prognostic parameters and receptor status.

Design: The sample consists of immunohistochemical profile of one hundred and fifty specimens of primary invasive breast cancer. Among these, fifty triple-negative phenotype breast cancer specimens are further assessed for, cytokeratin (CK) 5/6, epidermal growth factor (EGFR) and Ki-67.

Result: Out of 150 tumors studied, 68 (45.3%) are positive for estrogen receptor, 51(34.6%) for progesterone receptor and 5 cases are positive for Human epidermal growth factor receptor - 2. Large number of patients (65/150, 43.3%) are between the age group of 41 to 50years and had tumor size more than 2cm (119/150, 79.3%). Necrosis is observed in 72 of 150 (48.0%), ductal carcinoma in situ (DCIS) in 55 of 150 (36.7%) and majority of the tumors are of histological grade 2 (73/150, 48.6%). Most common histological subtype is Infiltrating ductal carcinoma, no special type (IDC NST) (91/150, 60.6%). Significant inverse association observed between tumor grade and hormone expression (p<0.05, OR 0.53, 95%CI 0.021 – 0.132), necrosis and hormone expression (p<0.05, OR 0.471, 95%CI 0.245 – 0.907).

                     A total of fifty cases of triple negative phenotype are further analyzed. Out of 50 triple negative phenotype breast cancers, 37 of 50 (74.0%) are positive for basal markers, cytokeratin (CK) 5/6 and or / epidermal growth factor receptor (EGFR) and 26.0% (13/50) cases are neither positive for EGFR nor for CK 5/6. Significant positive association is observed (p<0.05) between tumor necrosis and basal marker expression.

Summary and Conclusions: Breast cancer in our population presents at younger age and is histologically and by receptor profile more aggressive than western population, there by emphasizing role of morphological prognostic factors in molecular era.Triple-negative breast cancers harbor adverse pathobiological features and five marker immunohistochemical panels can be reliably used to define basal-like cancers.

Abstract:

Breast implant–associated ALCL is a new provisional entity in the WHO Classification of Tumor of Hematopoietic and Lymphoid Tissues (Revised 4^th edition, 2017).  It is not a disease of the breast parenchyma, but instead is a disease of the fibrous capsule surrounding the implant.  The patients usually present with an effusion around the implant and, rarely, with a solid mass. Morphologically, the neoplastic cells are large, epithelioid, and pleomorphic, with abundant cytoplasm, vesicular irregular nuclei, and frequent mitoses.  The lesional cells typically show strong and diffuse immunoreactivity for CD30 and often express T-cell markers, cytotoxic-associated antigens, and epithelial membrane antigen.  Almost all reported cases are negative for anaplastic lymphoma kinase.  Molecular genetic analyses have demonstrated T-cell receptor gene rearrangements. The differential diagnosis essentially includes poorly differentiated carcinoma, other lymphomas, and chronic inflammation.  Once a diagnosis of lymphoma is established, it is important to exclude systemic anaplastic lymphoma kinase–negative ALCL involving the breast, primary cutaneous ALCL, and other CD30+ lymphoproliferative disorders.  The patients with effusion-associated ALCL often have an indolent course and excellent prognosis, responding well to excision of the fibrous capsule around the implant (capsulectomy) and implant removal; the addition of chemotherapy does not appear to affect outcomes. In contrast, patients who present with a distinct mass may have a more aggressive course and poor prognosis, requiring chemotherapy and/or radiation therapy.
