BACKGROUND: Concurrent chemoradiation is the standard treatment for advanced cervical cancer. However some patients still have a poor prognosis, and currently, there is no effective treatment for recurrence. In recent years, 125I seed implantation therapy has emerged as a treatment for advanced malignant tumors including surgically unresectable tumors, residual tumors after surgical resection, and metastatic tumors. However, the use of 125I seeds implantation in primary advanced cervical cancer has not been reported. In this study, we present a case of stage IIIB cervical cancer in a patient who had poor response to radiotherapy and chemotherapy. Subsequently, a radical hysterectomy was performed, and 125I radioactive seeds were successfully implanted during the surgery. This effectively controlled the lesions that were resistant to radiotherapy and had the potential to improve the prognosis.
METHODS: A 56-year-old woman was diagnosed with stage IIIB (FIGO 2009) IIIC1r (FIGO 2018) squamous carcinoma of the cervix. After receiving 4 cycles of platinum-based chemotherapy and 30 rounds of radiotherapy, she underwent a radical hysterectomy. The localized cervical lesions were reduced, but there was no reduction in the size of the enlarged pelvic lymph nodes. Therefore, 125I seed implantation was performed under direct surgical vision for the right paracervical lesion and the enlarged pelvic lymph nodes on the right side. During the 18-month follow-up period, the enlarged lymph nodes subsided without any signs of recurrence or metastasis.
CONCLUSIONS: Intraoperative implantation of 125I seeds in lesions that are difficult to control with radiotherapy or in sites at high risk of recurrence is a feasible and effective treatment option for patients with advanced squamous cervical cancer, and it may contribute to improved survival.

BACKGROUND: Epithelial ovarian cancer (EOC) has the worst prognosis in all of gynecologic malignant tumors because of its high recurrence and eventually chemo-resistance. Early diagnosis of recurrence is crucial to avoid diffuse dissemination. Failure of traditional treatment in recurrent epithelial ovarian cancer remains a challenge for clinicians. On the other hand, 125I brachytherapy has been accepted as a useful and hopeful treatment for multiple advanced cancers in recent years. However, its success in advanced epithelial ovarian cancer is limited. Here we report a case of recurrent ovarian cancer who had been early diagnosis of isolated recurrence and successfully treated with 125I seeds implantation during suboptimal cytoreductive surgery.
METHODS: A 59-year-old woman presented with recurrent epithelial ovarian cancer who have had a history of ovarian cancer stage IIIB and an R0 resection had been achieved nearly 2 years before presented in our hospital. She underwent suboptimal secondary cytoreductive surgery after four cycles of chemotherapy with little effectiveness and severe chemotherapy-related side effects. Approximately 70% of the cancer-bulk was resected during surgery. For residual lesion which fixed around the right ureter and right external iliac vessel, 125I seeds implantation was performed. Postoperatively, the patient was treated with two cycles of combination chemotherapy with paclitaxel and carboplatin. The patient was free of disease at 26 months\' follow-up period.
CONCLUSIONS: In recurrent EOC patients with unresectable isolated lesion, salvage 125I seeds implantation are feasible and may contribute to survival.
