Abstract Introduction: Esophageal stenosis after chemotherapy in breast cancer patients is rare. It is important to distinguish esophageal stenosis from esophageal metastasis caused by breast cancer.Case presentation: We present the case of a 62-year-old woman who was diagnosed with breast cancer 4 months prior, had dysphagia and was referred to our department for further treatment after 2 cycles of chemotherapy. She suffered from severe mouth ulcers, painful swallowing and large areas of skin pigmentation with overlying scaliness after every chemotherapy session. Endoscopy revealed that the lumen of the lower esophagus was obviously narrow with ulceration above the stenosis. Histological results demonstrated inflammatory fibrinous necrosis and granulation tissue, with no clear neoplastic component. Conclusion: Short-term esophageal stenosis after chemotherapy may be caused by local mucosal injury, but malignant tumors need to be excluded.

Past Data

The second most causative disease is breast cancer happening in women and a significant explanation behind expanding death rate among women. Observed rates of this cancer are increasing with industrialization and also with early detection facilities. As the finding of this ailment physically takes extended periods and the lesser accessibility of frameworks, there is a need to build up the programmed determination framework for early identification of malignant growth. We have used machine learning classification techniques to categorize benign and malignant tumors, in which the machine learns from past data and predicts the new input category. Models like logistic regression and Random Forest are Done on the UCI dataset. Our experiments have indicated that Random Forest has the best prescient examination with exactness of ~96%.

Breast cancer is the most frequent and socially signifi cant malignant tumor disease of the female popula on of the Russian Federa on. At present, for the treatment of this pathology, the methods of the organ-preserving surgical manual allowing to achieve the maximum cosme c eff ect along with the observance of the principles of cancer safety are ge  ng more and more developed,. In recent decades, researchers from diff erent countries demonstrate the feasibility and technical safety of various mini-invasive methods of thermal abla on of early stages of breast cancer, characterized by rela ve simplicity of implementa on, excellent cosme c results, short-term rehabilita on of pa ents. These include hyperthermic techniques (radiofrequency, microwave, laser abla on) and hypothermic method (cryoabla on). Each technique has unique characteris cs of impact on the tumor and is performed under the control of ultrasound, computer tomography or magne c resonance imaging. The technical success of these abla on techniques is achieved in 93–98% of cases. Complete tumor necrosis a er radiofrequency abla on is observed in 76–100% of pa ents with breast cancer, laser abla on – in 13–76%, microwave abla on – in 0–8%, cryoabla on – in 36–83%. The frequency of development of specifi c complica ons of local thermal destruc on is 4–13%. To date, there is only one method of noninvasive extracorporeal thermal abla on of tumors of diff erent localiza on – high-intensity focused ultrasound therapy, the eff ec veness and safety of which as a method of local destruc on of benign and malignant tumors of the breast demonstrated by many authors. Like all methods of thermal abla on, high-intensity focused ultrasound therapy has its limita ons, complica ons and disadvantages. This ar cle presents a literary review that highlights the possibili es of this method of local destruc on in pa ents with malignant tumors of the breast.

BACKGROUND: Polymorphism of the genes of Human Epidermal growth factor receptor1 (HER1) and receptor2 (HER2) have been reported to be linked to pathogenesis of several malignant tumors but still there is contradiction regarding their association with breast cancer.OBJECTIVE: In this case control study we aimed to analyze the frequency ofHER1R497K (rs 11543848) andHER2I655V (rs 1136201) Polymorphisms in breast cancer.SUBJECT AND METHOD: The frequency ofHER1Arg(R) 497Lys (K) andHER2Ile (I) 655Val (V) polymorphisms were tested in 64 breast cancer patients and 86 normal control by polymerase chain reaction followed by restriction fragment polymorphism detection. Immunohistochemical analysis was done for HER2 protein on the available 18 malignant tissue samples.RESULTS:HER1497K andHER2655V variant had significantly increased breast cancer risk (OR=2.6, 95% CI 1.6–4.2, OR=2.2, 95% CI 1.2–4.1, p< 0.05) respectively. Moreover, combinedHER1K497 andHER2V655 variant was detected in 26.6% malignant in comparison to 8.14% of control group (OR=4.1, 95% CI 1.58–10.57), but, no significant association was noticed between both Polymorphisms and clinicopathological features of the disease. As regard HER2 immunohistochemical expression no significant correlation was revealed with HER2 655V polymorphism.CONCLUSIONS: Our findings suggest thatHER1497K andHER2655V polymorphisms are potential risk factor for development of breast cancer.

Cancer Related Fatigue

Breast cancer is one of the most common malignant tumors in women, which seriously threatens the health of women. With the improvement of living standards, the incidence rate of breast cancer is also rising. In the past ten years, the incidence rate of breast cancer in China’s major cities has increased by 37%, far higher than that in Europe and America. At present, chemotherapy and radiotherapy are the main treatment methods for breast cancer, but many patients will have cancer-related fatigue after surgery. Some studies believe that appropriate sports can improve cancer-related fatigue, but there is no specific research in this area. In view of this problem, this paper puts forward a rehabilitation training method based on gymnastics for breast cancer surgery. This paper is divided into three parts. The first part is the basic theory and core concept of breast cancer and cancer-related fatigue. Through the in-depth study of the theory, this paper believes that breast cancer patients paying attention to rehabilitation training can effectively improve cancer-related fatigue and affect the final therapeutic effect. The second part is the rehabilitation training program based on the way of gymnastics. The corresponding experimental model is established by using real cases as samples. In order to ensure the quality of the experiment, this paper gives the treatment plan in detail and establishes a unified evaluation system. In the third part of this paper, the relevant experiments and results analysis are given, and through data analysis, this paper believes that gymnastics can effectively help breast cancer patients with postoperative rehabilitation and continuous recovery of the upper limb function and improve cancer-related fatigue and other issues.

Elevated Glucose

Positron emission tomography (PET), with or without integrated computed tomography (CT), using 18F-fluorodeoxyglucose (FDG) is based on the principle of elevated glucose metabolism in malignant tumors, and its use in breast cancer patients is frequently being investigated. It has been shown useful for classification, staging, and response monitoring, both in primary and recurrent disease. However, because of the partial volume effect and limited resolution of most whole-body PET scanners, sensitivity for the visualization of small tumors is generally low. To improve the detection and quantification of primary breast tumors with FDG PET, several dedicated breast PET devices have been developed. In this nonsystematic review, we shortly summarize the value of whole-body PET/CT in breast cancer and provide an overview of currently available dedicated breast PETs.
