Rapidly Progressive High-Grade Leiomyosarcoma in an Elderly Patient

Area of Science:

• Oncology
• Surgical Pathology
• Geriatric Medicine

Background:

• High-grade leiomyosarcoma is a rare and aggressive soft tissue sarcoma.
• Elderly patients with comorbidities present unique challenges for cancer treatment.

Observation:

• An 84-year-old female presented with a rapidly enlarging proximal thigh mass diagnosed as high-grade leiomyosarcoma.
• The tumor demonstrated aggressive growth, doubling in size within two weeks.
• Post-operatively, the patient developed acute respiratory distress, pulmonary metastases, pulmonary embolism, and decompensated heart failure.

Findings:

• The patient experienced rapid clinical deterioration due to extensive metastatic leiomyosarcoma and complications.
• Neoadjuvant chemotherapy was precluded by patient frailty (cachexia).
• Despite anticoagulation and supportive care, the patient's status declined, leading to hospice care.

Implications:

• This case underscores the challenges of managing rapidly progressive sarcomas in frail elderly patients.
• Treatment decisions must carefully weigh potential benefits against toxicities in vulnerable populations.
• Multidisciplinary input is crucial for optimal patient selection for aggressive cancer therapies.
