High-grade versions of appendiceal goblet cell carcinoids (‘adenocarcinoma ex-goblet cell carcinoids’) are poorly characterized. We herein document 77 examples. Tumors occurred predominantly in females (74%), mean age 55 years (29–84), most with disseminated abdominal (77% peritoneal, 58% gynecologic tract involvement) and stage IV (65%) disease. Many presented to gynecologic oncologists, and nine had a working diagnosis of ovarian carcinoma. Metastases to liver (n =3) and lung (n =1) were uncommon and none arose in adenomatous lesions. Tumors had various histologic patterns, in variable combinations, most of which were fairly specific, making them recognizable as appendiceal in origin, even at metastatic sites: I: Ordinary goblet cell carcinoid/crypt pattern (rounded, non-luminal acini with well-oriented goblet cells), in variable amounts in all cases. II: Poorly cohesive goblet cell pattern (diffusely infiltrative cords/single files of signet ring-like/goblet cells). III: Poorly cohesive non-mucinous cell (diffuse-infiltrative growth of non-mucinous cells). IV: Microglandular (rosette-like glandular) pattern without goblet cells. V: Mixed ‘other’ carcinoma foci (including ordinary intestinal/mucinous). VI: goblet cell carcinoid pattern with high-grade morphology (marked nuclear atypia). VII: Solid sheet-like pattern punctuated by goblet cells/microglandular units. Ordinary nested/trabecular (‘carcinoid pattern’) was very uncommon. In total, 33(52%) died of disease, with median overall survival 38 months and 5-year survival 32%. On multivariate analysis perineural invasion and younger age (<55) were independently associated with worse outcome while lymph-vascular invasion, stage, and nodal status trended toward, but failed to reach, statistical significance. Worse behavior in younger patients combined with female predilection and ovarian-affinity raise the possibility of hormone-assisted tumor progression. In conclusion, ‘adenocarcinoma ex-goblet cell carcinoid’ is an appendix-specific, high-grade malignant neoplasm with distinctive morphology that is recognizable at metastatic sites and recapitulates crypt cells (appendiceal crypt cell adenocarcinoma). Unlike intestinal-type adenocarcinoma, it occurs predominantly in women, is disguised as gynecologic malignancy, and spreads along peritoneal surfaces with only rare hematogenous metastasis. It appears to be significantly more aggressive than appendiceal mucinous neoplasms.
Objective:
To examine the relationship of nutrition parameters with the modified frailty index (mFI) and postoperative complications in hip fracture patients.
Design:
Retrospective observational cohort study.
Setting:
Urban, American College of Surgeons–Verified, Level-1, Trauma Center.
Patients/Participants:
Three hundred seventy-seven consecutive patients with isolated hip fractures.
Intervention:
N/A.
Main Outcome Measures:
On admission, albumin and total lymphocyte count (TLC) levels and complication data were collected. Additionally, mFI scores were calculated. Statistical analysis was then used to analyze the association between frailty, malnutrition, and postoperative complications.
Results:
Overall, 62.6% and 17.5% of patients were malnourished as defined by TLC of <1500 cells per cubic millimeter and albumin of <3.5 g/dL, respectively. Both TLC (P = 0.024; r = −0.12) and albumin (P < 0.001; r = −0.23) weakly correlated with frailty. Combining malnutrition and frailty revealed predictive synergy. Albumin of <3.5 g/dL and mFI of ≥0.18 in the same patient resulted in a positive predictive value of 69% and a likelihood ratio of 4 (2.15–7.43) for postoperative complications. Similarly, the combination of hypoalbuminemia and frailty resulted in a positive predictive value of 23.3% and likelihood ratio of 8.52 (P < 0.001) for mortality.
Conclusions:
When patients are frail and malnourished, there is a risk elevation beyond that of frailty or malnutrition in isolation. This high-risk cohort can be easily identified at admission with routine laboratory values and clinical history. There is an opportunity to improve outcomes in frail hip fracture patients because malnutrition represents a potentially modifiable risk factor.
