Quality of life and functional outcomes after transanal total mesorectal excision for rectal cancer-results from the implementation period in Denmark.

BACKGROUND: The standard operation for mid- and low rectal cancer total mesorectal excision (TME) is routinely performed as minimally invasive surgery. TME is associated with temporary or permanent functional impairment of pelvic organs, causing reduced quality of life (QoL). Concerns have been raised that the newest minimally invasive approach, transanal TME (TaTME), may further reduce urogenital and anorectal functions. OBJECTIVE: To determine if functional outcomes affecting QoL are altered after TaTME. Primary end-point is the impact of TaTME on QoL and functional outcomes. Secondary end-point is assessing differences in QoL and functional outcomes after TME surgery from below (TaTME) or above (transabdominal TME). DESIGN, SETTING, AND PARTICIPANTS: Observational study consisting of prospectively registered self-reported questionnaire data collected at baseline and follow-ups after TaTME. All patients who underwent TaTME during the Danish national implementation phase were included. Central surveillance of the implementation included questionnaires concerning QoL and functional outcomes. Analyses of functional results from the Danish cohort of the ROLARR trial (Jayne et al. in JAMA 318:1569-1580, (2017) are reported separately for perspective, representing the transabdominal approach to TME, i.e., laparoscopic- or robotic-assisted TME (LaTME/RoTME). Applied questionnaires include EORTC QLQ-C30, SF-36, LARS, ICIQ-MLUTS, ICIQ-FLUTS, IPSS, IIEF, SVQ, and FSFI. RESULTS: A total of 115 TaTME procedures were registered August 2016 to April 2019. LaTME/RoTME patients (n = 92) were operated on January 2011 to September 2014. A temporary postoperative decrease of QoL (global health status and functional scales) was observed, yet long-term results were unaffected by surgery in both groups. In TaTME patients, the anorectal dysfunction increased significantly (p < 0.001) from preoperative baseline to 13.5 months follow-up, where 67.5% (n = 52) reported major LARS symptoms. Urinary function was not significantly impaired after TME regardless of technique. The paucity of responses concerning sexual function precludes conclusions. CONCLUSIONS: Although an initial reduction in QoL after TME occurs, it normalizes within the first year postoperatively. In concurrence with international results, we found that significant anorectal dysfunction is common after TaTME. No data on anorectal function was available for LaTME/RoTME patients for comparison. We found no indications that transanal TME is inferior to transabdominal TME surgery concerning urogenital functions or health-related QoL.

Has PET/CT a role in the characterization of indeterminate lung lesions on staging CT in colorectal cancer? A prospective study.

PURPOSE: CT has been found superior to chest x-ray to detect lung malignances. However, indeterminate lung lesions (ILL) are found in 4-42% by using CT in staging colorectal cancer (CRC) patients. Our aim was to examine the frequency of ILL on staging CT and the rate of the ILL being malignant, and to investigate if PET/CT was useful in pointing out the malignant cases. METHODS: A prospective analysis of 238 consecutive patients operated for CRC followed median 24 months. All the patients had a preoperative staging CT. Patients with ILL had a PET/CT scan performed 3 months postoperatively and low dose chest CT performed 6, 12, 18 and 24 months postoperatively. RESULTS: Twenty percent of the patients had ILL. Four of these patients (8.5%) had lung metastases detected median 9 months postoperatively, while 2 (4.3%) had other lung malignancies. One patient had TB. In patients with normal staging chest CT 10 of the 185 patients (5.4%) developed lung metastases detected median 16 months postoperatively. This was significantly later than in patients with ILL (p < 0.001), but with regard to the number of patients developing lung metastases no significant difference was found between the groups (p = 0.12). CONCLUSIONS: Even though a relative low number of ILL turn out to be malignant it seems advisable to use PET/CT scan in the follow-up to detect lung metastases as early as possible to better the prognosis. For the same reason all CRC patients should have chest CT included in their follow-up 6-12 months postoperatively.

[Recurrent infantile digital fibromatosis]. / Recidiverende infantil digital fibromatose.

In reflection of a current case, the latest literature concerning recurring infantile digital fibromatosis (Reye's tumour) are summed up. It is a non-malignant, rarely encountered tumour observed in children, appearing on the hands and feet. The tumour is almost exclusively diagnosed before the age of three. The etiology is unknown. Approximately 100 cases have been reported in the literature. Eosinophilic inclusion bodies near the nucleus of the tumourcells are pathognomonic. According to the latest literature, the content of the inclusions is mostly actin filaments between which the formed elements of the cell are entrapped. Previous treatment was repeated excision of the recurring tumours, until spontaneous cessation of disease activity. According to the latest literature, a more conservative treatment is recommended, because the fibromas often regress spontaneously over few years. Therefore surgical treatment is only needed in rare cases with aggressive or uncontrollable growth of the fibromas.
