Purpose To compare long-term choroidal vascular changes after iodine-125 brachytherapy (IBT) versus transpupillary thermotherapy (TTT) used as primary treatment of small choroidal melanoma. Methods Ninety-five small choroidal melanomas were randomized: 49 eyes with TTT and 46 eyes with IBT alone. Fluorescein and indocyanine green angiography (ICGA) were performed at 3-month intervals during the first year, and every 6 months thereafter. Results Mean follow-up was 56.2 months (range, 24–118 months; SD, 22.6). Tumor regressed in 45 (92%) TTT-treated vs 45 (98%) IBT-treated eyes (p=0.397). Four TTT-treated and one IBT-treated tumor recurred. Occlusion of choriocapillaris was present in all TTT and IBT cases. Closure of medium and large choroidal vessels was observed in 17 (35%) TTT-treated vs 44 (96%) IBT-treated eyes (p<0.001). Choroidal vascular remodeling was detected in 20 (41%) TTT-treated and 16 (35%) IBT-treated eyes (p=0.693). Retinochoroidal anastomosis was present in 4 of the 37 (11%) TTT-treated eyes with patency of medium and large choroidal vessels, but never observed in the IBT-treated eyes, and was associated with tumor recurrence. Among IBT-treated eyes, segments of choroidal vascular wall ICG staining and choroidal aneurysmal changes were detected in 30 (65%) and 7 (15%), respectively. These changes were never detected in TTT-treated cases (p<0.0001 and p=0.015, respectively). Conclusions The pattern of tumor choroidal vascular changes following IBT and TTT differs. TTT is less effective in closing all tumor vasculature. The role of long-term choroidal vascular remodeling observed after these two treatments needs longer follow-up.

A retrospective analysis of the immediate and long-term effectiveness of the treatment of the choroidal melanoma using transpupillary thermotherapy (TTT) was carried out. The study included 84 patients with choroidal melanoma (C69.3) who received treatment between 2007 and 2018. Patients were sampled from the Belarusian Cancer Register. The average values of the thickness of the tumor were 2.6±1.3 mm, the diameter of the base - 7.2±3.3 mm. TTT was carried out using a diode laser with a wavelength of 860 nm and radiation power of 200 - 800 mW, the exposure time was 60 s, and the diameter of the laser spot was varied between 1 and 3 mm. The entire surface of the tumor was thermally treated with overlapping fields from the periphery to the top. 75 patients underwent a single session of TTT, while 9 - two sessions with an interval of 3–4 weeks. As a result of the treatment, 51 (60.7%) patients showed complete tumor resorption, 28 (33.3%) patients had stabilization of the tumor process, and 5 (6.0%) patients had no effect. In the group of patients with stabilization of the tumor process, continued growth was recorded in 16 (19.1%) patients with follow-up periods of 3 months to 4 years. In 19 (37.3%) patients from the group with complete tumor regression, relapse was observed 1 to 8 years after TTT. Metastatic disease (disease progression) developed in 5 (5.9%) patients, of which in 1 patient during the first 12 months, in 1 patient - after 4 years, and in 3 patients more than after 5 years of the follow-up observation. Analysis of the effectiveness of TTT of choroidal melanoma showed that an increase in the thickness and diameter of the base of the tumor focus results in the decrease of immediate effectiveness, and the rise of the likelihood of continued tumor growth.

Abstract Background Mucosal healing is an important goal in the treatment of ulcerative colitis (UC). The newly published PICaSSO score characterises subtle mucosal and vascular changes and defines mucosal healing. We aimed to validate in real-life the PICaSSO score and assess its ability to predict relapse. Methods Patients with UC were prospectively recruited from 11 international centres. Participating endoscopists experienced in IBD received training on PICaSSO before starting the study. The rectum and sigmoid were examined using iScan 1,2 and 3 (Pentax, Japan) and inflammatory activity was assessed using UCEIS and PICaSSO. Biopsies were taken for the histological assessment using Robarts Histological Index (RHI) and Nancy. Follow-up was obtained at 12 months. Results A total of 278 patients were recruited (Table 1). The diagnostic performance in predicting histologic healing is shown in Table 2. When using PICaSSO score of ≤3 for mucosal and vascular architecture the AUROC to predict healing by RHI is 0.79 (95% CI 0.74–0.85) and 0.73 (95% CI 0.68–0.80) respectively and when using the Nancy score the AUROC is 0.78 (95% CI 0.72–0.84) and 0.77 (0.71–0.84). A total PICaSSO score of ≤8 and UCEIS score of ≤1 predicts remission at 12 months with an AUROC of 0.73 (0.65–0.80) and 0.71 (0.64–0.79). A Kaplan–Meier curve shows a favourable survival probability without relapse with a PICASSO score of ≤8 (Figure 1). Conclusion This real-life validation study shows the PICaSSO score can predict accurately histological healing and long-term remission and can be a useful tool in the management of UC.

Abstract. The effects of bromocriptine discontinuation after a 2 year course of therapy on prolactin (Prl) serum levels and the radiological size of the sella turcica were investigated in 16 women with amenorrhoea-galactorrhoea due to prolactinoma. During therapy, all but 2 patients had normalized serum Prl levels, and 4 women with macroprolactinomas exhibited a reduction in the size of the tumour as documented by CT-scanning and tomography of the sellae. After bromocriptine withdrawal and follow-up during 2 additional years, Prl levels remained normal in 6 patients, 2 of them with microprolactinomas and 4 with macroprolactinoma. The remaining 10 women developed hyperprolactinaemia associated with amenorrhoea and galactorrhoea within 3 months after discontinuation of therapy. No tumour expansion was observed in any case during the 4 year observation period. In the present study bromocriptine treatment seemed to result in permanent cure in 6 out of 16 cases of prolactinomas; nevertheless it is difficult to justify an indefinite medical treatment since the natural history of prolactinoma remains unknown. We presently feel that bromocriptine is more appropriate than neurosurgical transsphenoidal exploration for the primary treatment of prolactinomas. Further investigation is needed before a more definitive conclusion regarding the management of prolactinomas can be reached.

Hodgkin's Lymphoma

Adolescents and young adults (AYAs) are defined as those individuals between the ages of 15 and 39 years. Hodgkin’s lymphoma (HL) is the most common cancer observed in AYAs. Over the last two decades, significant improvements in both survival from HL and the reduction of therapy-related late effects have resulted from the work of collaborative study groups in pediatric and adult domains. The adolescent and young adult (AYA) population falls between these domains. AYA patients are in a critical developmental transition, with significant psychosocial challenges that may impact on the outcome of the primary treatment as well as on the medical care and surveillance of long-term sequelae in survivors. This article will examine available literature regarding outcomes for HL in the AYA population, identifying issues unique to this group, therapeutic options, and specific concerns in follow-up.

ABSTRACTChoriocarcinoma is the most malignant tumour of gestational trophoblastic origin. Most ovarian choriocarcinomas are gestational in origin and usually metastasize to the ovary from uterine or tubal choriocarcinoma. Non gestational choriocarcinoma (NGOC) of the ovary is exceedingly rare and usually seen along with other germ cell tumors. Non gestational choriocarcinoma has been found to be resistant to single-agent chemotherapy and has a worse prognosis than gestational choriocarcinoma. We are reporting long term follow up of published rare case of pure non gestational ovarian choriocarcinoma (NGOC) with concurrent metastases to the spleen and adrenal glands, who developed a delayed solitary brain metastases, two years after completion of primary treatment. Surgery along with triple agent chemotherapy and radiotherapy was found to give good remission in this aggressive disease.
