Background: Whether re-excision (RE) of a soft tissue sarcoma (STS) of limb or trunk should be systematized as adjuvant care and if it would improve metastatic free survival (MFS) are still debated. The impact of resection margins after unplanned macroscopically complete excision (UE) performed out of a NETSARC reference center or after second resection was further investigated.

Methods: This large nationwide series used data from patients having experienced UE outside of a reference center from 2010 to 2019, collected in a French nationwide exhaustive prospective cohort NETSARC.

Article Synopsis
  • The study utilized the NETSARC database to analyze management and outcomes of adolescents and young adults (AYAs) with sarcoma in France from 2010 to 2017, focusing on surgical cases.
  • Findings showed significant discrepancies in adherence to treatment guidelines between patients treated at reference sarcoma centers (RSC) and non-reference centers (non-RSC), with RSC having better rates of crucial pre-treatment procedures.
  • Despite similar overall survival rates (OS) for AYAs in both settings, those treated in RSC had notably better locoregional recurrence-free survival (LRFS) and progression-free survival (PFS), underscoring the benefits of multidisciplinary care in specialized centers.

Cancer genetics has to date focused on epithelial malignancies, identifying multiple histotype-specific pathways underlying cancer susceptibility. Sarcomas are rare malignancies predominantly derived from embryonic mesoderm. To identify pathways specific to mesenchymal cancers, we performed whole-genome germline sequencing on 1644 sporadic cases and 3205 matched healthy elderly controls.

Article Synopsis
  • The study investigates the prognosis of local invasive recurrence (LIR) in breast cancer patients with a history of carcinoma in situ (CIS) compared to those with de novo invasive breast cancer and LIR after primary invasive breast cancer.
  • Data was collected from a breast cancer registry over several years, analyzing outcomes such as overall survival (OS) and distant relapse-free survival (D-RFS) among matched patient groups.
  • Results indicate that there are no significant differences in survival outcomes between patients with LIR after CIS and those with other breast cancer types, suggesting that LIR after CIS does not negatively affect survival.

Background: The potential effects of breast cancer (BC) on health-related quality of life (HRQoL) should be considered in clinical and policy decision-making, as the economic burden of BC management is currently assessed. In the last decades, time-to-HRQoL score deterioration (TTD) has been proposed as an approach to the analysis of longitudinal HRQoL in oncology. The main objectives of the current study were to investigate the evolution of the utility values in BC patients after diagnosis and during follow-ups and to evaluate the TTD in utility values among women in all stages of BC.

Purpose: In the ACOSOG Z0011 trial, patients with primary breast cancer and 1-2 tumor-involved sentinel lymph nodes (SLNs) undergoing breast-conserving surgery had no oncological outcome benefit after axillary lymph node dissection (ALND), despite a relevant rate of non-SLN metastases of 27%. According to the St Gallen expert consensus, and NCCN and ASCO clinical guidelines, ALND may be avoided in patients who meet all ACOSOG Z0011 inclusion criteria. This recommendation can also be extended to patients undergoing mastectomy, with 1 or 2 positive SLNs and an indication for chest wall radiation, in whom axillary radiotherapy can be proposed as an alternative to completion ALND.

The aims of this educational review are to learn the semiological basis of soft-tissue lesions and, with the help of diagnostic algorithms, to apply the current recommendations for the management of soft-tissue tumors. Pseudotumors must first be identified and excluded. Among primary tumors, the search for macroscopic fat content on MRI is decisive; since it restricts the diagnostic range to adipocytic tumors.

Article Synopsis
  • Exosomes, tiny vesicles released by cells found in blood, can serve as potential cancer biomarkers by distinguishing between tumor-derived and non-tumor exosomes, particularly focusing on the presence of Heat Shock Protein-70 (HSP70) in cancer cells.
  • A clinical study investigated HSP70 exosomes in breast and lung cancer patients, revealing that levels in the blood were indicative of the HSP70 levels in tumor biopsies and varied significantly between metastatic and non-metastatic patients.
  • The findings suggest that monitoring circulating HSP70 exosomes could be a more sensitive method for predicting tumor spread and treatment response, indicating their potential utility in assessing patient outcomes.

Background: An important challenge of the longitudinal analysis of health-related quality of life (HRQOL) is the potential occurrence of a Response Shift (RS) effect. While the impact of RS effect on the longitudinal analysis of HRQOL has already been studied, few studies have been conducted on its impact on the determination of the Minimal Important Difference (MID). This study aims to investigate the impact of the RS effect on the determination of the MID over time for each scale of both EORTC QLQ-C30 and QLQ-BR23 questionnaires in breast cancer patients.

Article Synopsis
  • - The study evaluated the effectiveness of a 70-gene signature test (MammaPrint) in predicting outcomes for women with early-stage breast cancer, comparing genomic and clinical risk factors to decide on chemotherapy treatment.
  • - Out of 6693 enrolled women, 1550 were identified with high clinical risk but low genomic risk, and those not receiving chemotherapy showed a 5-year survival rate without distant metastasis of 94.7%.
  • - The findings suggest that some women at high clinical risk may safely forego chemotherapy based on low genomic risk, as their survival rates were comparable to those who received treatment.
