Synovial Sarcoma

Mechanistically, CBX3 binds directly to and SHH and prevents its ubiquitin-mediated degradation, thereby stabilizing the protein. CBX3-SHH subsequently suppresses mitochondrial oxidative metabolism, which in turn inhibits ferroptosis and facilitates EMT - ultimately promoting SS aggressiveness.

The biphasic EPCAM+ SyS has the highest levels of differentiation and lowest levels of the core oncogenic program. Our data complements the traditional classification of SyS and suggests that the monophasic mesenchymal SyS might consist of two molecular subtypes.

All patients underwent surgical intervention (tumor excision) followed by adjuvant chemotherapy with doxorubicin and ifosfamide. This case series highlights the clinicopathologic and molecular features of PCSS. Overall, SS18 (SYT) gene rearrangement and TLE1 expression are crucial diagnostic markers for differentiating PCSS from other neoplasms.

This case highlights the importance of maintaining a high index of suspicion for malignancy in deep-seated soft-tissue tumors. Early diagnosis, complete surgical removal, and multimodal therapy are crucial for the management of SS.

Extensive sampling, careful morphological observation, immunohistochemical staining and molecular detection of NAB2::STAT6 fusion are helpful for the diagnosis. It appears to have aggressive biological behaviors.

No recurrence was noted at 6-month follow-up. This case underscores the diagnostic challenge of GSS, the critical role of molecular techniques and the efficacy of minimally invasive surgical management.

Surgical margins were negative, and one-year follow-up showed that the patient remained disease-free. This case highlights the importance of immunohistochemistry and molecular testing for accurate diagnosis and appropriate management.

Early diagnosis, surgical resection, and adjuvant therapy can lead to significant symptomatic relief and may improve survival. This case highlights the value of integrating molecular diagnostics into the routine evaluation of rare cardiac tumors.

Immunohistochemistry plays a crucial role in interpreting a specific diagnosis or narrowing the differential diagnosis of SRCTs. Molecular genetic investigations are essential, particularly in cases exhibiting atypical or overlapping histologic and immunohistological features.

She received one cycle of anthracycline-ifosfamide chemotherapy but developed airway compromise and died on hospital day 34. This case illustrates the rapid progression and poor prognosis of primary pericardial synovial sarcoma, emphasizing that early recognition with multimodality imaging and timely surgical evaluation are crucial, as unresectable disease carries poor outcomes with current systemic therapies.

These findings suggest that PI3Kα is the dominant isoform, whereas PI3Kβ and PI3Kδ cooperate with PI3Kα in cell survival, which appears to be a characteristic feature of TRS cells. Thus, triple-isoform inhibition might represent an effective therapy for TRSs.
