Patients who undergo an appendectomy for acute appendicitis have a 58% lower relative risk of developing colorectal cancer compared to those treated with antibiotics alone, according to an analysis of more than 30,000 cases presented at the American College of Surgeons Clinical Congress. While antibiotic therapy has become an increasingly accepted alternative to surgery over the last decade, the study suggests that long-term oncologic risks should be considered when selecting a management strategy, Reuters reported.
Appendectomy Correlates with Lower Colorectal Cancer Risk
Researchers led by Dr. Valentine Nfonsam of the Morehouse School of Medicine in Atlanta evaluated data from 15,774 patients who underwent appendectomy and 15,295 who received antibiotic treatment. The study found that in the years following treatment, 0.7% of the surgical group was diagnosed with colorectal cancer, compared to 1.7% in the antibiotic-only group.
Nfonsam noted that while the appendix was historically viewed as a useless organ, emerging research indicates it may serve a function within the gut microbiome and the intestinal immune system. Although the study established a correlation between treatment type and cancer diagnosis, it was not designed to determine if persistent inflammation or microbiome changes are direct drivers of cancer development. Nfonsam emphasized that these findings do not necessitate surgery for all appendicitis patients, but they show that doctors must monitor long-term health outcomes for those managed non-operatively.
GLP-1 Users Report More Nail Detachment and Hair Loss
New data presented at the European Academy of Dermatology and Venereology Congress in Vienna points to potential side effects associated with the use of GLP-1 receptor agonists, commonly prescribed for diabetes and weight loss. Dr. Charles Taïeb of Necker University Hospital in Paris led a survey of 575 first-time GLP-1 users and 1,329 non-users, finding that 39% of the drug users reported nail detachment—where the nail separates from the underlying soft tissue—compared to 9% of the non-users.
A related study by the same research team observed that hair loss was more than twice as common among GLP-1 users, with 26% of users reporting shedding compared to 12% of non-users. Dr. Bruno Halioua, who led the hair loss research, stated that the presence of scalp symptoms like redness and itching suggests an inflammatory component that may extend beyond the hair shedding typically associated with rapid weight loss. While neither study confirms a causal link between the medications and these symptoms, researchers suggest that clinicians should remain vigilant for these dermatological changes.
Experimental CAR T-Cell Therapy for Stiff-Person Syndrome
Patients suffering from Stiff-person syndrome, a rare autoimmune disorder characterized by severe muscle rigidity and spasms, have shown sustained improvement following treatment with an experimental CAR T-cell therapy. The therapy, known as mivocabtagene autoleucel (miv-cel) and developed by Kyverna Therapeutics, improved walking ability and other clinical goals in a late-stage trial.
Kyverna Therapeutics reported that these therapeutic benefits persisted one year after treatment. The condition, which can cause heightened sensitivity to sound, touch, and emotional stimuli, gained public attention in 2022 when singer Celine Dion announced her diagnosis. Detailed results from the trial are expected to be presented at the upcoming joint ACTRIMS-ECTRIMS meeting in Toronto.
Does Everyone with Appendicitis Require Surgery?
Does everyone with appendicitis require surgery to lower cancer risk?
No. Dr. Valentine Nfonsam stated that these results should not be interpreted to mean that surgery is required for everyone, noting that antibiotic management remains an important option for many patients.
Is there a known cause for the nail and hair changes reported by GLP-1 users?
The studies presented in Vienna did not prove that GLP-1 treatment directly caused these changes. Researchers noted that while weight loss can influence hair health, the presence of scalp inflammation suggests that other factors may also contribute to the symptoms observed in patients.
How does the reported cancer risk compare to previous standards of care?
Historically, surgery was the standard of care for acute appendicitis, but the last decade saw a shift toward accepting antibiotic therapy as a primary treatment. This study provides a new perspective on the long-term oncologic implications of choosing non-operative management over surgical intervention.
