Overview
Historical Perspective
Pathophysiology
Causes
Differentiating Leiomyosarcoma from other Diseases:
| Disease | Clinical Features | Physical Examination | Diagnosis |
| Gastric cancer | Abdominal pain, Weight loss, Heartburn, Belching,Nausea,Vomiting,Weight loss,Loss of Appetite,Dysphagia,Hemetemesis,Melena | Pallor,Jaundice,Acanthosis Nigrans,Leasr-Trelat signs,Left supraclavicular Lypmph adenopathy,Abdominal mass and distension,Splenomegaly,Ascites,Hepattomegaly. | Esophagogastroduodenoscopy |
| Endometrial Cancer | Abnormal Vaginal bleeding,Post coital bleeding,Fatigue,weight loss,Pelvic pain and dysparunia | Tachycardia,Tachypnea,Pallor,Jaundice,Vaginal bleeding, Enlarged uterus,Pedal Edema,Hepatomegaly,Lymphadenopathy,Decreased breath sounds(depending upon the staging of the cancer) | CBC,LFT,CA-125,CA,PFT,xray chest,CT,MRI,Ultrasound, Endometrial Curettage,D and C,Endometrial Biopsy and Tru test. |
| Peptic Ulcer Disease | Episodic epigastric pain,fever,melena,hematemesis | Hypotension if perforation,Abdominal guarding and rigidity,normal bowel sounds | Ascites fluid analysis for LDH,glucose,and protein,chest xray if perforation,Upper GI Endoscopy,Serum gastrin level,Secretin stimulation test,Biopsy |
Epidemiology and Demographics:
- Leiomyosarcoma is one the most common types of soft tissue sarcoma, about 1 person in 100,000 gets diagnosed with LMS each year.Uterine sarcoma are extremely rare, with the incidence of 3 to 7 per 100,000 US population however rate of sarcoma appears to be rising as compared to early years.[1]
Risk Factors: Following Risk Fcators found to be associated with the development of the Uterine leiomyosarcoma
- Age: Leiomyosarcoma can be seen at 20 years of age but mean age at diagnosis is 50-60 years old.
- Race:Black women have a higher incidence of development of the uterine leiomyosarcoma as compared to the white women.[2]
- Long term use of the tamoxifen: Prolonged use of the tamoxifen esp more than five years has been associated with the increased risk of development of leiomyosarcoma.[3]
- History of Pelvic radiations:Pelvic irradiation has been associated with the increased development of the leiomyosarcoma.[4]
- Certain Hereditary condition like Gardner syndrome, Li-Fraumeni syndrome,Werner syndrome and Neurofibromatosis are associated with the development of leiomyosarcoma.
- Long term survivors of the Retinoblastoma are at higher risk of developing variety of soft tissue sarcoma.[5]
Natural History, Complications and Prognosis
- The majority of patients with leiomyosarcoma remain asymptomatic for decades.
- Most leiomyosarcomas are diagnosed incidentally at an advanced stage.
- They are invariably aggressive and associated with the poor prognosis.
Prognosis: The prognosis of leiomyosarcoma is poor and it depends on varying factors:
- Tumor size
- Tumor location
- Tumor type/Grade
- DNA content
- Hormonal receptor status
- cellular division and mitotic rate
- local and distant extension
Survival Rate of Leiomyosarcoma by staging:
| Stage | Percentage |
| stage 1 | 60 |
| stage 2 | 35 |
| stage 3 | 28 |
| stage 4 | 15 |
Diagnosis
History and Symptoms | Physical Examination | Laboratory Findings | Chest X Ray | CT | MRI | Ultrasound | Other Imaging Findings | Other Diagnostic Studies
Treatment
Leiomyosarcoma treatment consist of multidisciplinary approach and is best carried out at the specialized hospital setting.
Medical Therapy | Surgery | Secondary Prevention | Cost-Effectiveness of Therapy | Future or Investigational Therapies
