Definition: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Input: Question: Does irradiation Increase the Penetration Depth of Doxorubicin in Normal Tissue After Pressurized Intra-peritoneal Aerosol Chemotherapy ( PIPAC ) in an Ex Vivo Model?
Answer: Irradiation does not increase the penetration depth of doxorubicin into the normal tissue but might have a limiting impact on penetration and distribution of doxorubicin. Further studies are warranted to investigate the impact of addition of irradiation to PIPAC of tumor cells and to find out if irradiation can be used safely as chemopotenting agent for patients with peritoneal metastases treated with PIPAC.
Output:
no
