Embryonic cervical rhabdomyosarcoma complicated with uterine inversion with cerebral venous sinus thrombosis as the first symptom: a case report and literature review

Pleomorphic Rhabdomyosarcoma of the Uterine Corpus in an Adult Who Underwent Multi-gene Panel Testing

Background/Aim

Rhabdomyosarcoma (RMS) is the most common malignant soft tissue tumor in children. Adult primary RMS of gynecological origin is a rare condition and uterine RMS is an aggressive malignancy with a poor prognosis. The genetic variants associated with uterine RMS in adults have yet to be fully elucidated, and there is no established therapeutic strategy for rare tumors.

Case Report

A 69-year-old Japanese woman was referred to our hospital with abdominal bloating. Imaging examination revealed a tumor with diameter of 85 mm located in the uterus and multiple regional lymph node metastases. Biopsy of the uterine corpus indicated possible uterine carcinosarcoma or RMS. Following debulking surgery, the patient was diagnosed with stage IVB pleomorphic RMS. The patient was treated with two courses of doxorubicin every three weeks and one course of combination chemotherapy with vincristine, actinomycin, and cyclophosphamide. Because of rapid progression of the disease, we decided to perform multi-gene panel testing to determine the most effective therapeutic strategy. However, no therapeutic plan based on genetic information was identified. The patient with chemotherapy-refractory RMS died 11 weeks after surgery.

Conclusion

Our patient had advanced uterine RMS with an unresectable tumor that was resistant to chemotherapy, resulting in poor outcomes. Despite conducting multi-gene panel testing, no tailored therapeutic approach based on genetic information was found. This case highlights the challenges in managing uterine RMS in adults and underscores the urgent need for further research to identify effective treatment modalities.

Embryonal rhabdomyosarcoma of the uterine cervix in an adult female

Embryonal rhabdomyosarcoma (RMS) of the female genital tract is an uncommon malignancy, presenting mainly in the pediatric and adolescent populations, primarily affecting the first two decades of life. This malignancy presentation in adulthood is rare and is seldom seen. The incidence of this tumor affecting adult females is approximately 0.4 - 1%, with the common site being the vagina. This tumor infrequently involves the cervix. RMS has a poor survival rate and once diagnosed, it requires aggressive management by radical surgery accompanied by chemoradiation. We present a case of an anaplastic variant of embryonal RMS of the uterine cervix presenting as a cervical polyp in a 36-year-old female who complained of dyspareunia and post-coital bleeding.

Effects of low molecular weight heparin combined with hyperbaric oxygen on neurologic function and coagulation factors in patients with intracranial venous thrombosis

OBJECTIVE

To investigate the effects of low molecular weight heparin (LMWH) combined with hyperbaric oxygen (HBO) on the neurologic function and coagulation factors of patients with intracranial venous thrombosis (ICVT).

METHODS

The clinical data of 80 patients with ICVT admitted to the No. 2 Hospital of Baoding from February 2020 to January 2021 were retrospectively analyzed. Patients were assigned to a control group (n=32) and a research group (n=48) according to different treatment methods. The neurological function score, and the levels of D-dimer (D-D), fibrinogen (FIB), tumor necrosis factor-α (TNF-α), and C-reactive protein (CRP) were compared between the two groups. The two groups were also compared regarding the curative effect, toxic and side effects, as well as quality of life (QoL).

RESULTS

After treatment, the National Institutes of Health Stroke Scale (NIHSS) score was significantly lower in the research group compared to the control group. At 1, 2 and 3 weeks after treatment, the levels of D-D and FIB, as well as inflammatory factors TNF-α and CRP were lower in the research group compared to the control group. The overall response rate was significantly higher in the research group compared to the control group, while there was no significant difference in the total incidence of toxic and adverse effects between the two groups. After treatment, the QoL of patients assessed by the Generic Quality of Life Inventory-74 (GQOLI-74) from the domains of physical, social, and psychological function as well as material life status was significantly better in the research group.

CONCLUSIONS

LMWH combined with HBO can effectively improve the clinical efficacy and neurologic function of patients with ICVT and reduce the levels of coagulation factors and inflammatory factors.
