Background: Breast cancer is still considered as one of the most common female cancers worldwide regardless of the countries' level of development. This study determines the incidence of breast cancer in Fars Province, Southern Iran.
Methods: This study used patients' records from Shiraz University of Medical Sciences Cancer Registry Centre, which is a Hospital-Based Registry of Nemazee Hospital. Data were recorded based on International Classification of Diseases for Oncology (ICD-O) and compromised all invasive cancers in ICD-10 categories of C-00 to C-80. The findings were shown as the number of cases by site (ICD-10) and gender, with crude incidence (CRs), age-specific incidence and age-standardized incidence rates (ASRs) per 100,000 persons per year, performed by direct method using the world standard population.
Results: The age group of 40-49 years had the highest rate of breast cancer and naturally most cases were post-menopause ones. Most cases were diagnosed in moderate differentiated state with an increasing trend. Early diagnosis of in situ neoplasms has not increased over time in comprised with malignant cases. The number of diagnosed cases has sharply increased after year 2004 especially during post-menopause period.
Conclusion: As the number of diagnosed cases has increased during post-menopausal period, screening and health programs seem necessary for menopause women.

Background: HER2-targeted therapies have revolutionized the treatment of HER2-positive breast cancer patients, leading to significant improvements in tumor response rates and survival. However, resistance and incomplete response remain considerable challenges. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibition is a novel therapeutic strategy for the management of dyslipidemia by enhancing the clearance of low-density lipoprotein cholesterol receptors, however recent evidence also shows links between PCSK9 and cancer cells.

Background: Drug resistance constitutes one of the principal causes of poor prognosis in breast cancer patients. Although cancer cells can maintain viability independently of mitochondrial energy metabolism, they remain reliant on mitochondrial functions for the synthesis of new DNA strands. This dependency underscores a potential link between mitochondrial energy metabolism and drug resistance.

Background: Multiple studies have demonstrated that the abundance and functionality of γδ T cells are favorable prognostic indicators for prolonged survival in cancer patients. However, the association between the immunophenotype of circulating γδ T cells and the therapeutic response in NSCLC patients undergoing chemotherapy or targeted therapy remains unclear.
Methods: Patients with EGFR wild-type (EGFR-WT) or mutant (EGFR-Mut) non-small cell lung cancer (NSCLC), diagnosed between January 2020 and January 2024, were included in this study.

Background: Chemotherapy is a well-established therapeutic approach for several malignancies, including breast cancer (BCa). However, the clinical efficacy of this drug is limited by cardiotoxicity. Assessing multiple cardiac biomarkers can help identify patients at risk of adverse outcomes from chemotherapy.

Background: Disparities in lung cancer outcomes persist among Black Americans, necessitating targeted interventions to address screening inequities. This paper reports the development and refinement of Witness Project Lung, a community-based initiative tailored to the specific needs of the Black community, aiming to improve awareness and engagement with lung cancer screening.
Methods: Utilizing a user-centered design and guided by the original Witness Project framework - an evidence-based lay health advisor intervention program originally developed to increase knowledge and awareness about breast cancer risk and screening in the Black community and later trans-created to the cervical and colorectal cancer screening contexts - Witness Project Lung was developed and refined through qualitative input from key stakeholders in the Black faith community.
