A Randomized Trial of Laparoscopic versus Open Surgery for Rectal Cancer
In a randomized trial involving more than 1000 patients, outcomes including recurrence rate and overall survival were similar among patients undergoing laparoscopic surgery and those undergoing open surgery.
Colorectal cancer is the third most common cancer worldwide and accounts for nearly 1.4 million new cases and 694,000 deaths per year. Approximately one third of all colorectal cancers are localized in the rectum.

Deviations in RSV epidemiological patterns and population structures in the United States following the COVID-19 pandemic
Respiratory Syncytial Virus (RSV) is a leading cause of acute respiratory tract infection, with the greatest impact on infants, immunocompromised individuals, and older adults. RSV prevalence decreased substantially in the United States (US) following the implementation of COVID-19-related non-pharmaceutical interventions but later rebounded with abnormal seasonality. The biological and epidemiological factors underlying this altered behavior remain poorly defined. In this retrospective cohort study from 2009 to 2023 in Chicago, Illinois, US, we examined RSV epidemiology, clinical severity, and genetic diversity. We found that changes in RSV diagnostic platforms drove increased detections in outpatient settings post-2020 and that hospitalized adults infected with RSV-A were at higher risk of intensive care admission than those with RSV-B. While population structures of RSV-A remained unchanged, RSV-B exhibited a genetic shift into geographically distinct clusters. Mutations in the antigenic regions of the fusion protein suggest convergent evolution with potential implications for vaccine and therapeutic development.
Non-pharmaceutical interventions for COVID-19 also impacted the transmission of other viruses including respiratory syncytial virus (RSV). Here the authors describe the changing epidemiology, clinical severity, and genetic diversity of RSV in Chicago, Illinois, from July 2010 to April 2023.

Continued improvement in survival in multiple myeloma: changes in early mortality and outcomes in older patients
Therapy for multiple myeloma (MM) has markedly changed in the past decade with the introduction of new drugs, but it is not clear whether the improvements have been sustained. We studied 1038 patients diagnosed between 2001 and 2010, grouping patients into two 5-year periods by diagnosis, 2001–2005 and 2006–2010. The median estimated follow-up for the cohort was 5.9 years with 47% alive at the last follow-up. The median overall survival (OS) for the entire cohort was 5.2 years: 4.6 years for patients in the 2001–2005 group compared with 6.1 years for the 2006–2010 cohort (
P
=0.002). The improvement was primarily seen among patients over 65 years, the 6-year OS improving from 31 to 56%,
P
<0.001. Only 10% of patients died during the first year in the latter group, compared with 16% in the earlier cohort (
P
<0.01), suggesting improvement in early mortality. The improved outcomes were linked closely to the use of one or more new agents in initial therapy. The current results confirm continued survival improvement in MM and highlight the impact of initial therapy with novel agents. Most importantly, we demonstrate that the improved survival is benefitting older patients and that early mortality in this disease has reduced considerably.

We take no prisoners as they explore what really was, and mix in what might have been. Charlaine Harris [The Sookie Stackhouse Series, Midnight, Texas] shows us a glimpse inside her new series as a tormented gunfighter faces a true demon of her past. Mike Resnick [The Buntline Special] reveals what Doc Holiday thought was so funny on his last day. Jeffrey Mariotte [Desperados, Graveslingers] introduces us to a man who specializes in pictures of the dead who won't stay dead. Jane Lindskold [The Firekeeper Saga, The Star Kingdom Series (with David Weber)] teaches us not to underestimate a schoolmarm when her students are in jeopardy. And Shane Hensley [Deadlands] cooks up a stew that threatens to send every famous lawman in history to their graves! Plus, a dozen more stories of how the west was wilder than any history book could contain, such as a new Native American legend by Stephen Graham Jones and a Mormon troubleshooter straddling the line between his faith and the supernatural by D.J. Butler. The west that was rides again with west that could have been in this follow-up to Straight Outta Tombstone! Contributors: Mike Resnick D.J. Butler Jane Lindskold Shane Hensely Jeffrey J.

Laparoscopic versus open surgery for rectal cancer (COLOR II): short-term outcomes of a randomised, phase 3 trial
Laparoscopic surgery as an alternative to open surgery in patients with rectal cancer has not yet been shown to be oncologically safe. The aim in the COlorectal cancer Laparoscopic or Open Resection (COLOR II) trial was to compare laparoscopic and open surgery in patients with rectal cancer.
A non-inferiority phase 3 trial was undertaken at 30 centres and hospitals in eight countries. Patients (aged ≥18 years) with rectal cancer within 15 cm from the anal verge without evidence of distant metastases were randomly assigned to either laparoscopic or open surgery in a 2:1 ratio, stratified by centre, location of tumour, and preoperative radiotherapy. The study was not masked. Secondary (short-term) outcomes—including operative findings, complications, mortality, and results at pathological examination—are reported here. Analysis was by modified intention to treat, excluding those patients with post-randomisation exclusion criteria and for whom data were not available. This study is registered with ClinicalTrials.gov, number NCT00297791.
The study was undertaken between Jan 20, 2004, and May 4, 2010. 1103 patients were randomly assigned to the laparoscopic (n=739) and open surgery groups (n=364), and 1044 were eligible for analyses (699 and 345, respectively). Patients in the laparoscopic surgery group lost less blood than did those in the open surgery group (median 200 mL [IQR 100–400] vs 400 mL [200–700], p<0·0001); however, laparoscopic procedures took longer (240 min [184–300] vs 188 min [150–240]; p<0·0001). In the laparoscopic surgery group, bowel function returned sooner (2·0 days [1·0–3·0] vs 3·0 days [2·0–4·0]; p<0·0001) and hospital stay was shorter (8·0 days [6·0–13·0] vs 9·0 days [7·0–14·0]; p=0·036). Macroscopically, completeness of the resection was not different between groups (589 [88%] of 666 vs 303 [92%] of 331; p=0·250). Positive circumferential resection margin (<2 mm) was noted in 56 (10%) of 588 patients in the laparoscopic surgery group and 30 (10%) of 300 in the open surgery group (p=0·850). Median tumour distance to distal resection margin did not differ significantly between the groups (3·0 cm [IQR 2·0–4·8] vs 3·0 cm [1·8–5·0], respectively; p=0·676). In the laparoscopic and open surgery groups, morbidity (278 [40%] of 697 vs 128 [37%] of 345, respectively; p=0·424) and mortality (eight [1%] of 699 vs six [2%] of 345, respectively; p=0·409) within 28 days after surgery were similar.
In selected patients with rectal cancer treated by skilled surgeons, laparoscopic surgery resulted in similar safety, resection margins, and completeness of resection to that of open surgery, and recovery was improved after laparoscopic surgery. Results for the primary endpoint—locoregional recurrence—are expected by the end of 2013.

The impact of fluorescence angiography on anastomotic leak rate following transanal total mesorectal excision for rectal cancer: a comparative study
BackgroundAnastomotic leak (AL) is the most feared complication in colorectal surgery. Indocyanine green (ICG) fluorescence angiography allows for real-time intraoperative evaluation of bowel perfusion. This study aimed to assess the impact of ICG on perioperative outcomes in patients treated with transanal total mesorectal excision (TaTME) for rectal cancer.MethodsComparative study based on a retrospective analysis of prospectively collected data, to validate the use of ICG assessment (ICGA) during TaTME (November/2011–June/2018). The primary outcome was the clinical AL rate. The secondary outcomes included modification of proximal colonic transection, anastomotic redo, additional surgical maneuvers and surgical morbidity.ResultsTwo hundred and eighty-four patients were included, 204 (71.8%) in non-ICG group and 80 (28.2%) in ICG group. No significant differences were found in patient and tumor features. Mean anastomotic height was 4.85 cm vs. 5.04 cm (p = 0.500), diverting stoma was constructed in 205 patients (72.1% vs. 72.5%; p = 0.941). Fluorescence angiography modified the surgical plan in 23 patients (28.7%). AL was diagnosed in 23 patients (11.3%) in the non-ICG group and in two patients (2.5%) in the ICG group (p = 0.020). Postoperative intraabdominal collection was diagnosed in 19 patients (7.4% vs. 5.1%; p = 0.490), and reintervention was needed in 24 patients (10.8% vs. 7.6%; p = 0.420). Median length of hospital stay was 6.0 (IQR 5.0–9) vs. 4.0 (IQR 3.0–8.5) (p = 0.005). ICGA was found as independent protective factor for AL in the multivariate analysis of the whole cohort (n = 284) (OR 0.142; 95% CI 0.032–0.633; p = 0.010).ConclusionICG fluorescence angiography modified the proximal colonic transection in more than one-quarter of patients, leading to a significant decrease of AL rate.

NOTES transanal rectal cancer resection using transanal endoscopic microsurgery and laparoscopic assistance
Background
The feasibility and safety of Natural Orifice Translumenal Endoscopic Surgery (NOTES) transanal endoscopic rectosigmoid resection using transanal endoscopic microsurgery (TEM) was previously demonstrated in human cadavers and a porcine survival model. We report the first clinical case of a NOTES transanal resection for rectal cancer using TEM and laparoscopic assistance, performed by a team of surgeons from Barcelona and Boston with extensive experience with NOTES and minimally invasive approaches to colorectal diseases.
Methods
Transanal endoscopic rectal resection with total mesorectal excision using the TEM platform was performed in a 76-year-old woman with a T2N2 rectal cancer treated with preoperative chemoradiation. Laparoscopic visualization and assistance with retraction and exposure during rectosigmoid mobilization was provided through one 5-mm port, which was later used as the stoma site, and 2-mm needle ports, one of which was used as a drain site. The specimen was transected transanally followed by handsewn coloanal anastomosis.
Results
The procedure was completed successfully with an operative time of 4 hours and 30 minutes. Mesorectal excision was complete. The postoperative course was uneventful, and the patient was discharged on the fourth postoperative day. The final pathology demonstrated pT1N0 with 23 negative lymph nodes and negative proximal, distal, and radial margins.
Conclusions
NOTES transanal endoscopic rectosigmoid resection using TEM and laparoscopic assistance is feasible and safe. Careful patient selection and improvement in NOTES instrumentation are critical to optimize this approach before widespread clinical application.
