Exploring the Clinical Implications of RPL3 Presence in BRCA-Associated Cancers: Unraveling the Interplay With Cancer Immunity.

Background: Few studies have explored the expression profile of RPL3 in breast cancer (BRCA). Our research provided an in-depth analysis of RPL3 expression patterns in BRCA, highlighting its significance for therapy prediction and prognosis.

Methods: RPL3 was notably elevated in malignant cells, and its expression level was closely associated with tumor size and overall survival outcomes.

HER2-positive metastatic breast cancer with brain metastases responds favorably to pyrotinib and trastuzumab-based treatment: A case report and literature review.

For HER2-positive metastatic breast cancer patients with the brain involved at initial diagnosis, there was no standard regimen before 2022 when the HER2CLIMB trial published its final overall survival analysis, and the prognosis is relatively poor under the current treatment strategy. We herein reported a case of a female patient who was initially diagnosed with HER2-positive metastatic breast cancer with brain metastases, receiving pyrotinib and trastuzumab-based systematic therapy after palliative craniocerebral radiotherapy as the first-line systematic therapy. During the treatment, the tumor lesions showed obvious regression, and chemotherapy drugs were gradually removed from the regimen.

Delphian lymph node metastasis predicts occult contralateral carcinoma for unilateral papillary thyroid carcinoma patients with contralateral benign nodules.

Background: For unilateral PTC patients with benign nodules in the contralateral lobe evaluated preoperatively, the necessity of total thyroidectomy remains controversial. This study aimed to investigate the predictive factors for occult contralateral carcinoma and whether DLN metastasis could predict it.

Methods: A total of 148 patients with unilateral PTC and contralateral benign nodules who were treated with a near-total thyroidectomy or TT at a single institution between August 2018 and April 2020 were enrolled.

Prophylactic Central Neck Dissection for cN1b Papillary Thyroid Carcinoma: A Systematic Review and Meta-Analysis.

Background: The value of prophylactic central neck dissection (PCND) for papillary thyroid carcinoma (PTC) with clinically evident lateral cervical lymph node metastases (cN1b) remains unclear. Therefore, a systematic review and meta-analysis was conducted to assess the efficacy and safety of PCND.

Methods: A comprehensive systematic search was conducted on PubMed, Web of Science, Cochrane library and Embase databases up to September 2021 to identify eligible studies.

Retroperitoneal metastasis synchronous with brain and mediastinal lymph nodes metastasis from breast invasive ductal carcinoma as the first site of distant metastasis: a case report and review of literature.

Breast carcinoma retroperitoneal metastasis is rare. The clinical symptoms of this disease are always non-specific. Laboratory tests are not always helpful for diagnosis and evaluation.

Increased Expression of Exosomal AGAP2-AS1 (AGAP2 Antisense RNA 1) In Breast Cancer Cells Inhibits Trastuzumab-Induced Cell Cytotoxicity.

BACKGROUND Trastuzumab therapy is important for patients with HER2-positive breast cancer, but more and more patients have experienced trastuzumab resistance during recent years. Accumulating evidence from recent studies showed that long non-coding RNAs (lncRNAs) play essential roles in chemoresistance of various cancer types, but the precise role of lncRNAs in trastuzumab resistance is unclear. In the present study, we aimed to identify the biofunction of lncRNA APAP2-AS1 in tranastuzumab resistance and to reveal the underlying regulatory mechanism.
