Dear editor,Severe acute respiratory syndrome coronavirus2(SARS-CoV-2)infection can lead to severe outcomes in patients with cancer[1].It has been reported that patients with lung cancers disproportionately manifest severe COVID-19 with a high rate of hospitalization and death[2].Notably,the SARS-CoV-2 Spike(S)protein can induce hyper-inflammation in both epithelial cells and macrophages through toll-like receptor(TLR)1/TLR2 or TLR2/6-dependent nuclear factor-kappaB(NF-κB)path-way[3].However,molecular and cellular evidence on whether the SARS-CoV-2 virus affects the severity of lung cancer patients through TLR1/2 or TLR2/6 signaling remains unclear.

To facilitate gathering information during a psychiatric interview, some psychiatrists advocate augmenting the interview using drugs. Rather than barbiturates, benzodiazepines have been used for drug-assisted interviews. Dissociative amnesia is one of the indications for these interviews. Herein, we present the case of a 15-year-old female who was diagnosed as having dissociative amnesia because of conflicts with her friends. She was administered a Iorazepam-assisted interview to aid recovery of her memories. In this case, a small dose of Iorazepam was sufficient to recover her memories without any adverse effects.

AIM： To evaluate the efficacy and complications of stereotactic body radiotherapy in localized paraaortic lymph node recurrence from colorectal cancer. METHODS： From 2003 to 2009, 7 patients with paraaortic lymph node recurrence （1-3 lesions） from colorectal cancer were treated with stereotactic body radiotherapy. Total gross tumor volumes ranged from 4 to 40 mL. The doses were escalated from 36 Gy/patient to 51 Gy/patient and were delivered in 3 fractions. RESULTS： One and 3 year overall survival rates were 100% and 71.4%, respectively, and median survival was 37 mo. Grade IV intestinal obstruction was reported in 1 of 7 patients. This patient received 48 Gy in 3 fractions with a maximum point dose to the intestine of 53 Gy and V45Gy = 3.6 mL. However, 6 patients received an intestinal maximum point dose of 〈 51 Gy and V45Gy of 〈 1 mL, and did not develop any severe complications. CONCLUSION： This pilot study suggests selected paraaortic lymph node recurrence （1-3 closed lesions） that failed to respond to chemotherapy can be potentially salvaged by stereotactic body radiotherapy.
