The first thermic treatment predicts following chemoradiation response with concurrent thermal therapy for the treatment of rectal cancer.

The present study aimed to evaluate whether the neoadjuvant chemoradiation response with concurrent thermal therapy for the treatment of rectal cancer can be predicted following the first thermic treatment. Eighty patients with primary rectal adenocarcinoma (≤12 cm from the anal verge) were included in this study. Fifty-four received surgery and pathological response was evaluated.

Radiofrequency thermal treatment with chemoradiotherapy for advanced rectal cancer.

We previously reported that patients with a clinical complete response (CR) following radiofrequency thermal treatment exhibit significantly increased body temperature compared with other groups, whereas patients with a clinical partial response or stable disease depended on the absence or presence of output limiting symptoms. The aim of this study was to evaluate the correlation among treatment response, Hidaka radiofrequency (RF) output classification (HROC: termed by us) and changes in body temperature. From December 2011 to January 2014, 51 consecutive rectal cancer cases were included in this study.

Output-limiting symptoms induced by radiofrequency hyperthermia. Are they predictable?

Background: During radiofrequency (RF) hyperthermia treatment, hot-spot phenomena may occur and prevent treatment continuation if the output is not lowered. We previously reported a significant correlation between the initial energy output at which output-limiting symptoms occurred and patient status. Patients with a complete clinical response had significantly increased temperature, while some patients with partial clinical response and stable disease had increased temperature, depending on the occurrence of output-limiting symptoms.

A novel strategy of radiofrequency hyperthermia (neothermia) in combination with preoperative chemoradiotherapy for the treatment of advanced rectal cancer: a pilot study.

The safety of weekly regional hyperthermia performed with 8 MHz radiofrequency (RF) capacitive heating equipment has been established in rectal cancer. We aimed to standardize hyperthermia treatment for scientific evaluation and for assessing local tumor response to RF hyperthermia in rectal cancer. Forty-nine patients diagnosed with rectal adenocarcinoma were included in the study.
