[A case of successful radical resection of rectal cancer with neo-adjuvant chemoradiotherapy].

In cases of advanced rectal cancer, preoperative chemoradiotherapy( CRT) serves to improve the local control rate, survival rate, radical resection rate, and/or probability of sphincter muscle preservation. According to the Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines 2010 for the treatment of colorectal cancer, preoperative CRT is the standard treatment for rectal cancer in Europe and the United States. However, there is insufficient evidence in support of its efficacy and safety in Japan, and therefore, CRT needs to be evaluated in properly designed clinical trials.

It is common to use systemic chemotherapy, instead of hepatic arterial infusion (HAI) of 5-fluorouracil (5-FU) or other cytotoxic agents, for unresectable hepatic metastases in colorectal cancer patients. Nevertheless, systemic administration of anticancer agents such as FOLFOX or FOLFIRI is sometimes difficult to continue for infirm patients. A 71-year-old female who had undergone sigmoidectomy for sigmoid colon cancer received HAI for 12 months because of big bilobar hepatic metastases and poor performance status.

[Triple synchronous primary lung carcinomas in the same lobe; report of a case].

A 78-year-old female was referred to our department due to 3 abnormal shadows in the left lower lobe, that were S6, S8 and S10 by chest computed tomography (CT).
