Long-term results of salvage radiotherapy for the treatment of recurrent cervical carcinoma after prior surgery.
ABSTRACT Tumor recurrence after surgery for cervical carcinoma is associated with high fatality and morbidity, forming a major therapeutic challenge. This paper presents our experience with treatment of this patient group by salvage radiotherapy with curative intent.
Thirty-five patients with a pelvic recurrence after hysterectomy received high-dose radiotherapy. A retrospective analysis of long-term outcome and prognostic factors was performed.
After a median follow-up period of 12.1 years, actuarial 2-,5- and 10-year overall survival rates were 66%, 43% and 33%; disease-free survival rates were 62%, 45% and 41%, respectively. Pelvic control rates at 2-,5- and 10-years were 77%, 69% and 62%. Unfavorable prognostic factors on univariate analysis for survival were: recurrence extending to the pelvic wall versus central recurrence, early recurrence after surgery, external boost versus brachytherapy boost, low total dose and high age. Only a brachytherapy boost and a long interval between surgery and recurrence were significant on multivariate analysis. Severe complications (> or = grade 3) were seen in 6 patients (17%; actuarial after 5 years, 21%).
Salvage radiotherapy for recurrent cervical carcinoma following surgery may result in 40-50% long-term disease-free survival and an acceptable risk of severe treatment complications, even in patient with recurrences extending to the pelvic wall.

ABSTRACT: Evaluation of the results of salvage radiation therapy with curative intent in the treatment of recurrent cervical carcinoma. Fourteen patients with a recurrence of a cervical cancer were treated in our department between 1982 and 2009. Five patients had a pelvic relapse, four a vaginal relapse and five a pelvic lymph node relapse. Four patients had first a surgical resection of the relapse, which was incomplete in two patients. All patients had pelvic radiotherapy with a median dose of 55Gy in conventional fractionation. Concurrent chemotherapy was administered to 12 patients. A vaginal brachytherapy with a median dose of 20Gy was performed in addition in 3 patients. The median follow-up was 39months. Safety of radiation therapy was correct with 29% of grade 3 acute or intestinal toxicity. Tumor control was observed in 10 patients (71%). Four patients presented a locoregional tumor progression. At the time of analysis, three patients had died from their cancer. From the date of relapse, the rate of overall survival at 2 and 5year was respectively 84% and 74%. Three patients (21%) had severe late effects. In our experience, chemoradiotherapy can achieve a high rate of remission in patients with isolated pelvic recurrence of cervical cancer. This treatment is feasible only if the patient had not received radiation therapy before or if the relapse is out of the previously irradiated volume.Cancer/Radiothérapie 01/2014; 18(2).

ABSTRACT: In the present study, the preliminary results of the first stereotactic body radiosurgery (SRS) experience with volumetric intensity modulated arc therapy (VMAT) in oligometastatic breast and recurrent gynecological tumors (OBRGT) are reported in terms of feasibility, toxicity and efficacy. Patients were treated in a head-first supine treatment position on a customized body frame immobilization shell. SRS-VMAT treatment plans were optimized using the ERGO++ treatment planning system. Response assessment was performed 8-12 weeks after treatment by morphologic imaging modalities, or if feasible, also by functional imaging. Thirty-six lesions in 24 consecutive patients (median age, 63 years; range, 40-81) were treated: 13.9% had primary or metastatic lung lesions, 30.5% had liver metastases, 36.1% had bone lesions, 16.7% had lymph node metastases and 2.8% had a primary vulvar melanoma. The median dose was 18 Gy (BED2 Gy, α/β: 10=50.4 Gy), the minimal dose was 12 Gy (BED2 Gy, α/β: 10=26.4 Gy) and the maximal dose was 28 Gy (BED2 Gy, α/β: 10=106.4 Gy). Seven patients (29.2%) experienced acute toxicity, which however was grade 2 in only 1 case. Moreover, only 3 patients (12.5%) developed late toxicity of which only 1 was grade 2. Objective response rate was 77.7% including 16 lesions achieving complete response (44.4%) and 12 lesions achieving partial response (33.3%). The median duration of follow-up was 15.5 months (range, 6-50). Recurrence/progression within the SRS-VMAT treated field was observed in 6 patients (total lesions=7) with a 2-year inside SRS-VMAT field disease control expressed on a per lesion basis of 69%. Recurrence/progression of disease outside the SRS-VMAT field was documented in 15 patients; the 2-year outside SRS-VMAT field metastasis‑free survival, expressed on a per patient basis, was 35%. Death due to disease was documented in 6 patients and the 2-year overall survival was 58%. Although the maximum tolerated dose was not reached, SRS-VMAT resulted in positive early clinical results in terms of tumor response, local control rate and toxicity.Oncology Reports 08/2014; 32(5).

ABSTRACT: Abstract Background: Concomitant hyperthermia has been shown to improve response rate after cisplatin in recurrent cervical cancer in previously irradiated patients. It is unclear whether similar response rates can be obtained in patients with a recurrence after previous platinum-containing chemoradiation. Objective: This study aimed to evaluate the outcome of cisplatin-based chemotherapy with concurrent hyperthermia in patients with recurrent cervical cancer after radiotherapy and cisplatin. Methods: Patients with recurrent cervical cancer after cisplatin-based chemoradiation or neoadjuvant chemotherapy followed by surgery and radiotherapy who were treated with concurrent platinum-based chemotherapy and hyperthermia were eligible for this retrospective analysis. All patients received six or eight weekly platinum-based chemotherapy cycles in combination with six or eight weekly hyperthermia sessions. The time-to-event variables were estimated using Kaplan-Meier analysis. P-values less than 0.05 were considered significant. Results: All 38 evaluable patients were selected from the hyperthermia database in the Academic Medical Centre (Amsterdam) and the Erasmus Medical Centre (Rotterdam). Mean age at relapse was 45.7 years (range 27-74). Median time to recurrence after first-line treatment was 15 months. A total of 27 patients had a local and/or regional recurrence; 11 had disease beyond the pelvis. All planned courses of cisplatin chemotherapy and hyperthermia were administered in 17/38 patients. Median follow-up was 6.5 months. One patient died during treatment; response rate was 4/37 (14%), with one complete response. Overall survival was 23% at 12 months and 4% at 24 months. The incidence of grade 3-4 haematological complications did not exceed 10%. Conclusion: In this retrospective study, concurrent cisplatin and hyperthermia after first-line cisplatin-containing chemoradiation showed poor response and survival. We do not recommend this treatment for recurrence of locally advanced cervical cancer.International Journal of Hyperthermia 10/2013; DOI:10.3109/02656736.2013.844366 · 2.77 Impact Factor
