Objective: Tumor surgeons now pay special attention to the alteration in breast form following breast-conserving surgery. Safety of breast-conserving margins and postoperative breast appearance are typically challenging in conventional breast-conserving surgery due to the effect of variables such as big breast tumors or unusual placements. It's important to remember that postoperative breast deformity is a real possibility. Breast-conserving tumor plastic surgery combines tumor excision with plastic surgery, allowing for a more thorough removal of the tumor. It provides a more humane treatment option for the majority of patients by ensuring the safety of surgical margins, considering the aesthetic effects, increasing the breast-conserving opportunities for patients with tumors in special parts, and expanding the indications for breast-conserving surgery. It also greatly improves the postoperative quality of life and mental state. In this article, we deeply examine the current state of knowledge concerning the effectiveness, safety, and appropriate patient population for breast-conserving surgery in the context of tumor plastic surgery.

Background: Treatment given as a first step to shrink a tumor before the main treatment, which is usually surgery, is given. Examples of neoadjuvant therapy include chemotherapy, radiation therapy, and hormone therapy. It is a type of induction therapy. The most common pattern of esophageal cancer metastases (ECM) is to the lymph nodes, lung, liver, bones, adrenal glands, and brain. Case Presentation: A male patient, 47 years old, was admitted to the hospital on July 31, 2020, mainly due to "progressive dysphagia. Two months ago, the patient had difficulty eating without obvious incentives, especially when eating hard food such as rice. The liquid diet was acceptable, accompanied by retrosternal pain and discomfort, heartburn, and obvious weight loss. The symptoms gradually aggravated without obvious relief. Conclusion: In summary, there are few international investigations and an absence of relevant information and literature on the environment in which tumor cells survive after radiotherapy. Clinicians can't ignore the issue of whether radiotherapy will alter the tumor cells' natural environment, leading to tumor cell escape and an increase in brain    metastases.

Background: In the face of the COVID-19 pandemic, surgical personnel and patients experience many diagnosis and treatment-related challenges. COVID-19 is highly virulent, and thus, immediate, safe, and effective solutions to the patients’ management are required. Research collaboration and knowledge dissemination are necessary to optimize medical and surgical approaches to the individual patients’ needs. Gastric manifestations of SARS-CoV-2 infection are not uncommon and may even precede respiratory symptoms. Common gastrointestinal symptoms include loss of appetite, diarrhea, nausea, vomiting and abdominal pain. Case Presentation: A 50-year-old male patient complained of "blood in the stool and tenesmus for half a year" and was admitted to the hospital on March 2, 2023. Half a year ago, the patient had blood in the stool without obvious incentives, the bleeding was bright red, the habit of defecation changed, the stool became thinner, and the frequency of defecation increased, 3-5 times a day, and the amount was not much. At that time, he went to a regular medical institution for any treatment measures.
