Long-Term Outcomes of Chemoradiation for Anal Cancer Patients
نویسندگان
چکیده
PURPOSE The aim of this study was to evaluate long-term oncologic outcomes after concurrent chemoradiation treatment for anal cancer. MATERIALS AND METHODS Between January 1979 and December 2008, the records of 50 consecutive patients with anal cancer and who were treated by chemoradiation or radiation only with a curative intent were retrospectively reviewed. The oncologic outcomes and the risk factors for recurrence were analyzed. RESULTS Of the 50 patients, 49 underwent concurrent chemoradiation and one underwent radiation only. After these definitive treatments, 43 (86.0%) achieved a clinical complete response. During the median follow-up of 60 months (range: 2-202 months), the 5-year overall survival, disease-free survival, and locoregional recurrence-free survival were 84.2%, 72.7%, and 69.9%, respectively. Multivariate analysis revealed that the performance status (p=0.031) and a clinical complete response (p=0.039) were the independent predictors for overall survival; lymph node involvement (p=0.031) was the only independent predictor for disease-free survival. CONCLUSION The performance status and a clinical complete response may be reliable predictors of survival after chemoradiation for anal cancer. The addition of irradiation to the inguinal area may not be significantly associated with the outcomes.

New drug in neoadjuvant chemoradiation for rectal cancer
Background: In recent years, neoadjuvant chemoradiation and subsequent surgical resection with total mesorectal excision has been shown to increase local control with decreased toxicity. Neoadjuvant chemoradiotherapy is the standard treatment for locally advanced rectal cancer. In this study we evaluated the efficacy a cox-2 inhibitor on pathologic response, sphincter preservation and acute tox...
متن کاملOutcomes of anal cancer treated with definitive IMRT-based chemoradiation
Objective Despite excellent long-term outcomes, definitive chemoradiation (CRT) for squamous cell carcinoma (SqCC) of the anal canal with traditional radiotherapy techniques results in significant morbidity. Accruing data supports intensity-modulated radiotherapy (IMRT)-based treatment, and we report our institutional experience using this approach. Methods We reviewed patients with nonmetastat...
متن کاملIntensity-modulated radiation therapy for anal cancer.
The contemporary treatment of anal cancer is combined-modality therapy with radiation therapy, fluorouracil, and mitomycin. This therapy results in long-term disease-free survival and sphincter preservation in the majority of patients. Tempering these positive results is the high rate of treatment-related morbidity associated with chemoradiation therapy for anal cancer. The use of intensity-mod...

Tumor size seems to be a determinant in the prognosis of early cervical cancer. Patients with tumor size greater than 4 cm (bulky) in diameter have worse outcome.' The purpose of this study was to compare the efficacy of preoperative combined chemoradiation and neoadjuvant chemotherapy (NArC) programs followed by radical hysterectomy in stage Ib - lIb bulky cervical cancer. From September ...
