The role of adjuvant endocrine treatment in ER+, PR-, HER2- early breast cancer: a retrospective study of real-world data.

Purpose: Estrogen receptor-positive (ER+), progesterone receptor-negative (PR-) and human epidermal growth factor receptor 2-negative (HER2-) breast cancer (BC) often developed resistance to endocrine treatment (ET). We aimed to explore (1) the different clinicopathological features between ER+/PR+/HER2- and ER+/PR-/HER2- BC, and (2) whether ER+/PR-/HER2- early BC patients could benefit from adjuvant ET.

Methods: All patients treated for ER+/HER2- early BC who underwent surgery between 2010 and 2021 from a BC database in China were retrospectively examined.

Impact of Lung Metastasis versus Metastasis of Bone, Brain, or Liver on Overall Survival and Thyroid Cancer-Specific Survival of Thyroid Cancer Patients: A Population-Based Study.

We investigate the impact of lung metastasis versus metastasis of bone, brain, or liver on overall survival (OS) and thyroid cancer-specific survival (TCSS) in patients with thyroid cancer (TC). Therefore, de-identified SEER 18 registry data of primary TC patients diagnosed between 2010 and 2016 were analyzed. The primary outcome was the prognosis of TC patients with lung metastasis compared with other sites.

Preoperational diagnosis and management of breast ductal carcinoma arising within fibroadenoma: Two case reports.

Background: Ductal carcinoma (DCIS) arising within fibroadenoma is a type of tumor that is rarely encountered in clinic, with only about 100 cases of carcinoma arising within a fibroadenoma reported in the literature. Here, we present two cases of breast DCIS arising within a fibroadenoma and discuss their clinical and imaging findings as well as treatment.

Case Summary: The patients did not have cancer-related personal and family histories.

Autophagy-related prognostic signature for survival prediction of triple negative breast cancer.

Background: Triple-negative breast cancer (TNBC) is a highly aggressive type of cancer with few available treatment methods. The aim of the current study was to provide a prognostic autophagy-related gene (ARG) model to predict the outcomes for TNBC patients using bioinformatic analysis.

Methods: mRNA expression data and its clinical information for TNBC samples obtained from The Cancer Genome Atlas (TCGA) and Metabric databases were extracted for bioinformatic analysis.

Thyrotropin suppression therapy using levothyroxine does not negatively affect breast cancer prognosis.

Introduction: Breast cancer (BC) and thyroid dysfunction are common in females, yet the relationship between thyroid hormone and BC is unclear. To search for the connection between thyrotropin and BC, we contradistinguished BC patients with or without synchronous second primary thyroid cancer (TC) with surgery using data from the Surveillance, Epidemiology, and End Results (SEER) database. Theoretically, according to the ATA (American Thyroid Association) guidelines, all TC patients were treated with thyrotropin suppressive therapy only from 2010 to 2015.

Risk and prognosis of secondary bladder cancer after post-operative radiotherapy for gynecological cancer.

The aim of this study was to investigate the impacts of radiation therapy (RT) on the occurrence risk of secondary bladder cancer (SBC) and on the patients' survival outcome after being diagnosed with gynecological cancer (EC). The data was obtained from the SEER database between 1973 and 2015. Chi-squared test was used to compare the clinicopathological characteristics among the different groups.

Breast cancer-derived exosomes transmit lncRNA SNHG16 to induce CD73+γδ1 Treg cells.

γδT cells have been reported to exert immunosuppressive functions in multiple solid malignant diseases, but their immunosuppressive functional subpopulation in breast cancer (BC) is still undetermined. Here, we collected 40 paired BC and normal tissue samples from Chinese patients for analysis. First, we showed that γδT1 cells comprise the majority of CD3+ T cells in BC; next, we found that CD73+γδT1 cells were the predominant regulatory T-cell (Treg) population in BC, and that their prevalence in peripheral blood was also related to tumour burden.

Survival of Patients with First and Metachronous Second Primary Breast Cancer or Lung Cancer Malignancy: Comparisons Using the SEER Database.

Introduction: Breast cancer (BC) and lung cancer (LuC) are common malignancies. The survival of patients with metachronous second primary malignancy (MSPM) of BC and LuC after a first primary of BC and LuC remains unclear.

Methods: Data of patients with BC and LuC, with or without MSPM of BC and LuC, who were diagnosed from 2000 to 2014, were extracted from the Surveillance, Epidemiology, and End Results (SEER) database.

Prospective study of the relevance of circulating tumor cell status and neoadjuvant chemotherapy effectiveness in early breast cancer.

Although unequivocal evidence has shown the prognostic relevance of circulating tumor cells (CTCs) in patients with metastatic breast cancer (MBC), less evidence is available for its significance in neoadjuvant chemotherapy (NCT) in early breast cancer (BC). Here we conducted an analysis of individual data from 86 patients confirmed as invasive BC by core-needle biopsy in Zhejiang Provincial People's Hospital between June 2013 and January 2017. The CTCs were assessed at the time after diagnosis and before surgery with the CanPatrol technique.

Oncoplastic breast reconstruction with omental flap: A retrospective study and systematic review.

The increasing frequency of early breast cancer cases has driven an increasing number of patients to choose immediate reconstruction with an autologous flap. Omentum-flap-based breast reconstruction is a unique strategy that is highly suitable for repairing moderate tissue defects. However, all available evidence comes from individual reports with small numbers of cases, and the overall effectiveness and safety of the procedure have yet to be reported.

Radiotherapy and nipple-areolar complex necrosis after nipple-sparing mastectomy: a systematic review and meta-analysis.

Objective: To perform a meta-analysis to determine the effect of radiotherapy (RT) on nipple-areolar complex (NAC) and skin flap necrosis, and local recurrence in women who undergo nipple-sparing mastectomy (NSM) and immediate breast reconstruction.

Methods: Medline, PubMed, Cochrane, and Google Scholar databases were searched until October 16, 2015. Randomized-controlled-trials, prospective, retrospective, and cohort studies were included.
