Extrafascial hysterectomy after concurrent chemoradiotherapy in locally advanced cervical adenocarcinoma / 부인종양

OBJECTIVE: To evaluate whether adjuvant simple hysterectomy after concurrent chemoradiotherapy (CCRT) improves progression-free survival (PFS) compared with current standard care in locally advanced cervical adenocarcinoma (LACAC). METHODS: We reviewed a cohort of 55 patients with LACAC (International Federation of Gynecology and Obstetrics [FIGO] stage IB2, IIA2, IIB, III without distant metastasis) diagnosed and treated with radical CCRT at Peking Union Medical College Hospital between January 2004 and October 2014. We compared 34 patients who underwent adjuvant extrafascial hysterectomy with 21 patients with standard care after CCRT. The primary outcome was PFS. Overall survivals (OS) between the two groups were also compared. Surgery feasibility, operative complications, and pathologic features after radiation therapy were also analyzed. RESULTS: PFS was significantly improved in surgery group (log-rank p=0.0097; hazard ratio [HR], 0.3431; 95% CI, 0.152 to 0.772), as were OS (log-rank p=0.0419; HR, 0.3667; 95% CI, 0.139 to 0.964). Analysis of stage IIB demonstrates a similar result. There were no severe complications related to postradiation surgery in this series. The mean blood loss was less in laparoscopic group than those in the open group (87 mL vs. 208 mL, p=0.036, Mann-Whitney U-test). Approximately 47% patients (16/34) had pathologic residue tumor on hysterectomy specimens. About 94% patients (32/34) got complete remission after adjuvant surgery. CONCLUSION: Adjuvant hysterectomy after CCRT improves survival outcome for patients with LACAC compared with current standard care. Extrafascial hysterectomy is sufficient in tumor reduction and laparoscopic procedure may be more promising with lower blood loss and expedite recovery.

Histerectomía extrafascial en cáncer de cuello uterino IB2 posterior a radio-quimioterapia / Extrafascial hysterectomy in IB2 cervical cancer after radiochemotherapy

Objetivo: Evaluar la sobrevida global y libre de enfermedad en pacientes con tratamiento concomitante de radioquimioterapia más histerectomía extrafascial en cáncer de cuello uterino IB2. Método: 31 pacientes con cáncer cérvico-uterino en etapa IB2 fueron tratadas con radioquimioterapia concomitante más histerectomía extrafascial programada en 4 a 6 semanas. Se efectuó radioterapia pelviana externa e implante de braquiterapia útero-vaginal con dosis preoperatoria entre 70-75 Gy a punto A y quimioterapia con cisplatino. Resultados: La edad promedio de las pacientes fue de 41 +/- 8 años. El 81 por ciento de los casos fue carcinoma escamocelular. La histerectomía extrafascial se realizó 4 a 6 semanas post-radiación en el 85 por ciento de los casos. El 79 por ciento y el 13 por ciento de las pacientes recibieron 5 y 4 ciclos de quimioterapia respectivamente. La mediana de seguimiento fue de 38 meses. La sobrevida global y libre de enfermedad estimada a 5 años fue de 86 por ciento y 79 por ciento respectivamente. Hubo diferencia significativa en la sobrevida global en los subgrupos sin o con enfermedad residual macroscópica en la pieza operatoria (p<0,001). Conclusión: Esta serie muestra resultados de sobrevida similares a las reportadas en otros trabajos con el mismo tratamiento. La enfermedad residual en la pieza operatoria podría constituir un factor de valor pronóstico.

Aim: To evaluate overall and disease free survival in cervical cáncer IB2 patients with concomitant chemo-radiotherapy and posterior extrafascial hysterectomy treatment. Methods: Between July 2005 to December 2009, a total of 31 eligible patients with IB2 cervical cancer were treated with chemoradiotherapy and posterior hysterectomy in the Carlos Van Buren Hospital Oncology Unit. Radiotherapy consisted in external pelvic radiation and a utero-vaginal brachitherapy with low rate doses to get preoperatory doses between 70 and 75 Gy to the A point and a concomitant Cisplatin based chemotherapy. After this treatment, the patients received extrafascial hysterectomy 4 to 6 weeks completed chemoradiotherapy. Results: The mean age was 41 +/- 8 years. 81 percent of the patients had an spinocelular carcinoma. The extrafascial hysterectomy was made between 4 to 6 weeks post-radiation in 85 percent of the patients. 79 percent and 13 percent of the patients received 5 and 4 chemotherapy cycles respectively. The median follow up was 38 months. The 5 years overall survival and disease free survival estimates were 86 percent and 79 percent respectively. There was a significant difference between subgroups of patients with and without macroscopic residual disease in the operatory specimen (p<0.001). Conclusion: Our survival is similar to published results with the same treatment. The presence of macroscopic residual disease in the hysterectomy specimen could be a factor of prognostic value.
