Radiotherapy skin marking with lancets versus electric marking pen - Comfort, satisfaction, effectiveness and cosmesis results from the randomized, double-blind COMFORTATTOO trial

INTRODUCTION

Set-up skin markings are performed, in several centers, for radiotherapy (RT) treatments. This study aimed to compare two permanent methods: lancets and an electric marking pen, the Comfort Marker 2.0® (CM).

METHODS

This was a prospective, unicentric, randomized study. Patients aged 18 years or older referred to our department to receive RT were recruited. Patients were randomly assigned, in a 1:1 ratio, to receive set-up markings using lancets or CM. The markings arrangement followed our departmental protocols. The coprimary endpoints were patients' comfort and effectiveness. Secondary endpoints included radiation therapists (RTTs) satisfaction and cosmesis.

RESULTS

Between October 2021 and January 2022, 100 patients were enrolled (50 received lancets and 50 CM) and assessed for the comfort and satisfaction outcomes. CM was significantly less painful than the lancets, with 44% and 16% of the patients, respectively, considering the tattooing process painless (RR = 2.75; 95% IC: 1.36 - 5.58). On the RTT-reported satisfaction, CM had significantly easier processes than lancets (98.0% vs. 78.0%, respectively; RR = 1.26; 95% CI: 1.08 - 1.46). For effectiveness and cosmesis assessment, 98 patients were analyzed (48 received lancets and 50 CM). Patients receiving CM had a significantly higher proportion of markings graded as good and excellent compared to those receiving lancets (98.0% and 50.0%, respectively, had ≥75% of the tattoos assessed as good/excellent, RR = 1.96; 95% CI: 1.47 - 2.61). On the cosmetic evaluation, patients receiving CM had significantly better cosmetic markings, with a median score of 4.4 (vs. 3.5 for lancets, p <0.001).

CONCLUSION

The trial results demonstrated that tattooing with the CM is significantly less painful, more effective, easier to apply, and cosmetically superior to tattooing with lancets.

IMPLICATIONS FOR PRACTICE

Tattooing with CM allows for better results regarding pain, quality, ease and cosmesis.

Surgical treatment of schistosomal portal hypertension

Schistosomiasis mansoni is a widespread parasitic disease in the Brazilian territory that affects over 8 million individuals. Hepatosplenic schistosomiasis is a serious clinical presentation of this disease, associated with splenomegaly, liver fibrosis, and portal hypertension, and is responsible for approximately 7% of schistosomotic patients. The surgical treatment of portal hypertension in schistosomotic patients has distinct features when compared with cirrhotic patients, mostly because hepatic function is preserved in schistosomotic liver disease. Therefore, when attempting to reduce the portal pressure, the surgeon must be aware that the surgery might interfere with hepatic perfusion, and consequently with hepatic function. The aim of this study was to report the results achieved with splenectomy, division of the left gastric vein, devascularization of great gastric curvature, and postoperative endoscopic variceal sclerosis, as a surgical option to esophageal varices in hepatosplenic schistosomiasis. A total of 111 patients were studied, and the following is a list of inclusion criteria: age >16 years, history of gastrointestinal (GI) bleeding, presence of esophageal varices on preoperative endoscopy, hematocrit >22% and prothrombin enzymatic activity >50%, negative viral hepatitis on serologic tests (anti-HBV and anti-HCV), and definition, after liver biopsy, of exclusive schistosomotic liver disease. The following list includes exclusion criteria used: presence of liver disease other than schistosomotic, history of alcohol abuse, and preoperative thrombosis of the portal vein. The rebleeding rate was 14.4% during a mean 30-month follow-up period; portal vein thrombosis was 13.2%, and there was a global mortality of 5.4%. Gastric varices were present in 46.9% of the patients; for those patients, a gastrotomy and running suture of the varices achieved an eradication rate of the varices of 75.6%. The degree of periportal fibrosis was also analyzed. Periportal fibrosis staging revealed that patients with class II or III liver fibrosis had a significant increased risk of recurrent GI bleeding when compared with patients with class I liver fibrosis. Despite the elevation on alanine aminotransferase (ALT) and aspartate aminotransferase (AST), most other liver function tests showed no alteration or were corrected after surgery. We conclude that splenectomy, division of the left gastric vein, devascularization of great gastric curvature, and postoperative endoscopic variceal sclerosis showed good results globally and should be considered as therapeutic options in the treatment of hepatosplenic schistosomiasis.
