Accurate localization of rectal cancer using near infrared ray-guided surgery with intra-operative colonoscopy and da Vinci Firefly technology

AbstractAccurate localization of the tumor during robot-assisted laparoscopic surgery for rectal cancer is crucial. Several techniques have been described, but each has its shortcomings. We developed a new technique of near infrared ray-guided surgery (NIRGS) to localize the tumor accurately, using intra-operative colonoscopy and da Vinci Firefly technology. After clamping the oral side of the tumor, the colonoscope was inserted. In the normal visible light mode, we could not recognize the endoscopic light; however, after changing to the Firefly mode, the endoscopic light was seen clearly. Using this simple and new technique, we could locate the tumor easily and accurately. We performed this technique in 12 patients and detected the location of the tumor clearly in all, without any procedure-related complications. Based on these findings, NIRGS is a useful and safe technique for detecting tumor location during robot-assisted laparoscopic surgery for rectal cancer.

Conclusions: 3D-HDR-BT achieves favorable clinical outcomes with mild late toxicity in patients with locally rNPC. Introduction Nasopharyngeal carcinoma (NPC), a tumor of epithelial origin, is a malignant disease of the head and neck common in southern China, especially in Guangdong province (1). As a result of advances in modern imaging and irradiation techniques, the 5-year overall survival (OS) of patients with newly diagnosed NPC without metastasis has reached 75% after external beam radiotherapy (EBRT) in Asia (2, 3). However, local recurrence, which occurs in 18–40% of patients, remains a major reason for...

In this report, we are adding an extra finding, in which we show that the levels of circulating NRP-1 were significantly increased in patients who received NAC and had a partial response. Assessing patients who underwent NAC indicated that the levels of NRP-1 measured post-NAC were significantly higher in younger patients and patients with either a low or a medium body mass index (BMI), as well as in patients who remained with larger tumor size and partial response. Previously, we showed that SNAI1 expression in the immune cells collected from the peripheral blood of breast cancer patients was significantly higher in patie...

Conclusions: Catching errors prior to treatment is the only way to “chase zero” in radiation oncology. Various types of errors may exist in treatment plans and our GCPR model succeeds in preventing many errors of all shapes and sizes in target definition, dose prescriptions, and treatment plans from ever reaching the patients. Background and Introduction Since the release of the seminal report from the Institute of Medicine (IOM) titled, “To Err is Human,” in 1999, the importance of patient safety and avoiding medical errors have been recognized and endorsed by the physician community, as we...

CONCLUSIONS: The study showed a high pCR rate with no severe toxicity, good follow-up results, and good loco-regional control. Therefore, addition of oxaliplatin to preoperative CRT with S-1 in patients with LARC might be feasible and lead to better local control than standard treatment. PMID: 31005216 [PubMed - in process]
