Lymphocyte to monocyte ratio-based nomogram for predicting outcomes of hepatocellular carcinoma treated with sorafenib

BACKGROUND

The ability of the pretreatment lymphocyte to monocyte ratio (LMR) to predict outcomes of patients with hepatocellular carcinoma (HCC) receiving sorafenib is not conclusively determined.

METHODS

We retrospectively studied patients treated with sorafenib for HCC in two tertiary referral centres in Asia and North America. Primary endpoints were overall survival (OS) and progression-free survival (PFS). Predictive factors for the outcomes were determined by Cox proportional hazards models. A risk assessment tool was developed.

RESULTS

Compared to the North America cohort, the Asia cohort was more heavily pretreated (72.1% vs. 35.2%; p < 0.001), had higher hepatitis B virus infection (87.6% vs. 5.6%; p < 0.001), and more distant metastases (83.2% vs. 25.4%; p < 0.001). Lower monocyte count in the Asia cohort (median 462.7 vs. 600.0/μL; p = 0.023) resulted in a higher LMR (median 2.6 vs. 1.8; p < 0.001). High LMR was associated with a significantly higher OS [hazard ratio (HR) 0.88; 95% confidence interval (CI) 0.81‒0.97; p = 0.007]. This was confirmed in a sensitivity analysis including patients treated in Asia only (HR 0.89; 95% CI 0.81‒0.97; p = 0.010). An OS nomogram was constructed with the following variables selected in the multivariate Cox model: LMR, treatment location, previous treatment, performance status, alpha-fetoprotein, lymph node metastasis, and Child‒Pugh score. The concordance score was 0.71 (95% CI, 0.67‒0.75). LMR did not predict PFS.

CONCLUSION

LMR measured before sorafenib administration predicts OS in advanced HCC patients. Our OS nomogram, incorporating LMR, can be offered to clinicians to improve their ability to assess prognosis, strengthen the prognosis-based decision-making, and inform patients in the clinic.

Acrylic intraocular lens placement in conjunction with pars plana vitrectomy

PURPOSE

To report the results of placing a foldable acrylic intraocular lens through a clear cornea incision in eyes undergoing pars plana vitrectomy.

METHODS

This interventional case series is a retrospective report of 15 eyes of 15 consecutive patients undergoing foldable (acrylic) intraocular lens insertion in conjunction with pars plana vitrectomy in a single academic institution. Outcome measures included visual acuity and complications.

RESULTS

The intraocular lens was successfully implanted and retained in position in all 15 cases. The intraocular lens did not pose difficulty in examining the fundus or cause any vitreoretinal complications. With mean follow-up of 4.5 months (range, 1--10 months), final median postoperative visual acuity range was 20/200 (range, 20/40--2/200) and consistent with the level of vitreoretinal disease.

CONCLUSION

Acrylic intraocular lenses may be safely implanted in conjunction with pars plana vitrectomy in selected cases.
