Clinicopathologic features and survival outcomes of ocular melanoma: a series of 31 cases from a tertiary university hospital

Background@#We aimed to determine the effect of clinicopathologic features on overall survival among Caucasian ocular melanoma patients in the Central Anatolia region of Turkey. @*Methods@#This single-center study included conjunctival (n = 12) and uveal (n = 19) melanoma patients diagnosed between January 2008 and March 2020. Clinicopathologic features and outcomes were reviewed retrospectively. Five cases were tested for BRAF V600 mutations with real-time polymerase chain reaction, and one case was tested with nextgeneration sequencing. Survival was calculated using the Kaplan-Meier method. @*Results@#Thirty-one patients had a mean initial age of 58.32 years (median, 61 years; range 25 to 78 years). There were 13 male and 18 female patients. The median follow-up time was 43.5 months (range, 6 to 155 months) for conjunctival melanoma and 35 months (range, 8 to 151 months) for uveal melanoma. When this study ended, eight of the 12 conjunctival melanoma patients (66.7%) and nine of the 19 uveal melanoma patients (47.4%) had died. The presence of tumor-infiltrating lymphocytes was related to improved overall survival in conjunctival melanoma (p = .014), whereas the presence of ulceration (p = .030), lymphovascular invasion (p = .051), tumor in the left eye (p = .012), tumor thickness of > 2 mm (p = .012), and mitotic count of >1/mm² (p = .012) reduced the overall survival in conjunctival melanoma. Uveal melanoma tumors with the largest diameter of 9.1–15 mm led to the lowest overall survival among subgroups (p = .035). Involvement of the conjunctiva (p=.005) and lens (p = .003) diminished overall survival in uveal melanoma. BRAF V600 mutation was present in one case of conjunctival melanoma, GNAQ R183Q mutation was present in one case of uveal melanoma. Patients with uveal melanoma presented with an advanced pathological tumor stage compared to those with conjunctival melanoma (p = .019). @*Conclusions@#This study confirmed the presence of tumor-infiltrating lymphocytes as a favorable factor in conjunctival melanoma and conjunctival and lens involvement as unfavorable prognostic factors in uveal melanoma for overall survival, respectively.

Uterine smooth muscle tumor of uncertain malignant potential: fertility and clinical outcomes / 부인종양

OBJECTIVE: In this study, we aimed to evaluate the clinicopathological features, obstetric, and oncological outcomes of patients diagnosed with a uterine smooth muscle tumors of uncertain malignant potential (STUMP). METHODS: A dual-institutional, database review was carried out to screen patients with STUMP who were treated with upfront surgery between January 2006 and December 2017. Data including age at the time of diagnosis, recurrence rate, disease-free survival, overall survival, and fertility outcomes were retrospectively analyzed. RESULTS: Fifty-seven patients with STUMPs were included in the study. The median age at the time of diagnosis was 42 (range, 16 to 75) years. The median follow-up was 57 (range, 16 to 125) months. Eight patients (14%) had recurrence during follow-up. Recurrent STUMPs were seen in seven patients and leiomyosarcoma after 14 months in one patient. Seven patients with a recurrent STUMP survived, while the remaining patient died. Recurrence rates were similar for women who underwent myomectomy and those who underwent hysterectomy. The presence of uterine localization of tumor (subserosal vs intramural-submucosal) statistically significantly affected recurrence rates (odds ratio=5.72; 95% confidence interval=1.349–24.290; p=0.018). Ten of 27 patients who underwent myomectomy for uterine myoma had fertility desire. Seven pregnancies were recorded. CONCLUSIONS: Our study results suggest that fertility-sparing approaches are feasible in patients with STUMP, although recurrence may be seen.

Increased insulin-like growth factor binding protein-3 expression level in psoriatic tissue before and after systemic treatment with cyclosporine A and methotrexate.

Insulin-like growth factor (IGF) and its binding proteins (BPs) are candidates to play a role in the pathogenesis of psoriasis. IGF-I and -II and their binding proteins (IGFBPs) have both growth inhibitory and mitogenic effects on a multitude of cell types. Current studies have explored the potential role of IGFBP-3 in keratinocyte growth and differentiation. To gain more insight into the role of IGFBP-3 in the pathogenesis of psoriasis, we investigated the changes in IGFBP-3 expression levels in psoriatic plaque and compared these expressions with levels in other inflammatory skin diseases. In particular, we investigated whether or not the changes in IGFBP-3 were affected by systemic treatment with cyclosporine A (CsA) or methotrexate (Mtx). We found significantly increased IGFBP-3 expression levels in the psoriatic group compared with levels in patients with other, nonproliferative inflammatory skin diseases, and we demonstrated differences in distribution pattern before and after systemic treatment with Mtx or CsA. Mtx and CsA had no effect on tissue IGFBP-3 expression levels. Before treatment with Mtx or CsA, IGFBP-3 expression was limited to the basal layer and suprapapillary region. Unlike with Mtx, CsA significantly changed the IGFBP-3 distribution pattern.
