Thus, it was not possible anal ascertain the reason patients were treated with local excision. Although the use of chemoradiotherapy for the management of SCCAC has been a paradigm for organ-preserving treatment approaches, our data suggest that future work evaluating the effectiveness of local excision for select patients with T1N0 disease would be of substantial value. Efforts directed at increasing disease awareness and screening of at-risk populations would likely improve early detection rates, thereby making local excision a reasonable treatment option.

Meaning This study suggests the need for future trials to confirm the oncologic efficacy of local excision for the management of select patients with squamous cell carcinoma of the anal canal. Objectives To examine the use of local excision among patients with T1 SCCAC and to compare overall survival relative to those who received standard treatment with chemoradiotherapy.
Main Outcomes and Measures Overall survival. Conclusions and Relevance The use of local excision alone girlsdoporn scenes the management of T1N0 SCCAC has significantly increased over time, with no clear decrement in overall survival.

Figure 2. Figure 3. Discussion Although there have not been any recent, meaningful changes in the management of SCCAC, over time there have been several advances in our understanding of risk factors and anal cancer precursor lesions. Limitations Our data must be interpreted in the context of several notable limitations. Conclusions Although the use of chemoradiotherapy for the management of SCCAC has been a paradigm for organ-preserving treatment approaches, our data suggest that future work evaluating the effectiveness of local excision for select patients with T1N0 disease would be of substantial value.
