    The leaves of Nerium indicum Mill. have been utilized traditionally to cure cancer. By Bioassay (BST) guided isolation method, six compounds were isolated from the CHCl3 extract of the leaves. Selectivity of these compounds (in 0.6-12,500 ng/ml) was tested on various human cancer (MCF7, EVSA-T, T47D, H226, IGROV, A498, WIDR, M19, HeLa) and normal (Vero) cells in vitro. Doxorubicin and cysplatin were used as positive controls. The result indicated that NiO2D (5alpha-oleandrin) possessed the best cytotoxic effect on HeLa cells (IC50, 8.38 x10(-6) mM) and NiO2C (16, 17-dehidrodeasetil-5alpha-oleandrin) on A498 cells (IC50, 1.43 x 10(-6) mM). Those two compounds were not cytotoxic to normal cell.

    We report our experience with intralesional injection of bleomycin in the treatment of neck lymphangioma. From May 1995 to April 1998, 11 patients aged between 6 to 22 months were treated with intralesional bleomycin injection. Ultrasonography and computed tomography were used to assess and select the cases suitable for sclerotherapy. Patients with lesions encasing the internal jugular vein and the carotid artery were chosen. With the patient under sedation and using ultrasound guidance, the cysts were aspirated and bleomycin was injected at a dose of 0.5 mg/kg body weight. The number of procedures varied from 1 to 4 over a period of 8 months to 1 year. Patients were initially followed-up 3 monthly, then 6 monthly and subsequently yearly. In 4 patients, the neck mass was no longer visible (excellent response). In 5 patients, the neck mass had reduced to a size (more than 50% reduction) that was cosmetically acceptable (good response). There were 2 failures (poor response). There were no complications. Our results suggest that intralesional injection of bleomycin can be effectively used to treat selected cases of neck lymphangiomas.

    A unique phenomenon in solid tumors, the enhanced permeability and retention (EPR) effect is now well known in the development of macromolecular anticancer therapy. However, cancers with low vascular permeability have posed a challenge for these EPR based therapeutic systems. An intrinsic vascular modulator, such as nitric oxide (NO), could augment the endogenous EPR effect. However, the most important aim has been to construct an effective NO delivery system for cancer. Since it is well known that human serum albumin is one of the most important endogenous NO transport proteins in human circulation, for more than a decade we have demonstrated that S-nitrosated human serum albumin dimer (SNO-HSA-Dimer) becomes an enhancer of the EPR effect. Here, we summarize the enhanced effect of SNO-HSA-Dimer on the anticancer effect of macromolecular anticancer drugs such as PEGylated liposomal doxorubicin (Doxil®). In C26-bearing mice with highly permeable vasculature, SNO-HSA-Dimer is able to increase more 3-fold the tumor accumulation of these anticancer drugs, thereby tripling their anticancer effects. Interestingly, the tumor accumulation of Doxil® in B16-bearing mice, which are characterized by a low permeable vasculature, increased more than 6-fold in the presence of SNO-HSA-Dimer, and the improved accumulation of Doxil® led to both increased survival and decreased tumor volume. These results strongly suggest that the more cancer is refractory, the more the SNO-HSA-Dimer could enhance the EPR effect via an endogenous albumin transport (EAT) system. Accordingly, we conclude that the EAT system is promising as a drug delivery system (DDS) strategy for refractory cancer therapy.

    BACKGROUND: Our study compared the outcomes of three different therapies: surgery (Group I), bleomycin sclerotherapy (Group II), and a combination of both (Group III), for children with common (cystic) lymphatic malformation (LM) at a paediatric surgical centre in Yogyakarta, Indonesia.

    METHODS: Medical records of patients who were treated for LM in the Paediatric Surgical Centre Universitas Gadjah Mada from January 2015 to January 2019 were reviewed. Scoring systems were used to assess the outcomes, including reduction of size, problems of aesthetics, functional problems, complications, necessity of further interventions, and interventions' frequencies.

    RESULTS: During the four-year study, we included 31 children, consisting of 6, 5, and 20 patients in Groups I, II, and III, respectively. The total score did not significantly differ between Groups I, II, and III (14.67±2.80 vs. 13.40±2.07 vs. 12.50±1.47, respectively; p=0.056). Group II scored better in aesthetic problems than other groups (p=0.001), Group III scored higher in necessity of further interventions compared to the other groups (p=0.026), and Group I was higher in interventions' frequencies than the other groups (p<0.001). However, there were no significant differences in reduction of size, functional problems, and complications among groups (p=0.554, 0.151, and 0.076, respectively).

    CONCLUSIONS: There is no significant different effect of the three modalities treatment for LM, although one group might have more beneficial effects compared with the other groups due to different scoring system parameters. Further multicentre and prospective cohort studies with a larger number of patients are necessary to establish the existence and extent of our findings.

    BACKGROUND: Cancer and heart diseases are the leading causes of morbidity and mortality in many countries worldwide. Recent advancement in chemotherapy and targeted therapies has led to an improvement in cancer survival rates, but at a cost of higher cardiac side effects. However, report on antineoplastic-related cardiotoxicities incidence in Asia is lacking.

    METHODS: We systematically searched multiple databases to identify studies reporting incidence of antineoplastic-related cardiovascular toxicity in Asia published from inception to November 2018. Pre-specified subgroups were performed to explore heterogeneity and study quality assessed and reported according to PRISMA guidelines.

    RESULTS: A total of 61 studies across 11 countries in Asia reported 8 types of cardiovascular toxicities were included. These studies mostly reported on adult populations, and usually examined cardiotoxicities related to anthracycline use. The most frequently reported cardiotoxicities were heart failure, electrocardiogram abnormalities and left ventricular dysfunction. The pooled estimated incidence of cardiotoxicity was 4.27% (95% CI: 3.53-5.07). Subgroup analysis showed higher incidence in middle income countries compared to high income countries.

    CONCLUSIONS: Although robust incidence studies are sparse, cardiovascular complications affects approximately one in twenty cancer patients in Asia. This highlights a unique opportunity of cancer patients caring that need cardiologists and oncologist to become familiar with this emerging sub-specialty.

    Choanal stenosis is a well recognized late complication of radiotherapy for nasopharyngeal carcinoma. However velopharyngeal stenosis post radiotherapy for nasopharyngeal carcinoma is rare. We present here a case of bilateral choanal stenosis and velopharyngeal stenosis in a patient treated with radiotherapy for nasopharyngeal carcinoma. A 58-year-old woman presented to our otolaryngology clinic with a one year history of nasal obstruction. She was diagnosed to have nasopharyngeal carcinoma 12 years ago for which she received radiotherapy. Clinical examination revealed bilateral choanal stenosis and velopharyngeal stenosis. Treatment of choanal stenosis and velopharyngeal stenosis is challenging due to high incidence of recurrence and patients frequently require multiple procedures. The patient underwent a transnasal endoscopic excision of velopharyngeal scar tissue and widening of posterior choana using Surgitron®, mitomycin-C applied topically to the surgical wound and bilateral stenting under general anesthesia. The stents were kept for two weeks, and 3 years post operation velopharyngeal aperture and posterior choana remained patent. As illustrated in this case velopharyngeal stenosis can occur after radiotheraphy and should not be overlooked. Combine modality of transnasal endoscopic excision of velopharyngeal scar tissue, widening of choanal stenosis with Surgitron® followed by the application of mitomycin-C and stenting has been shown to be an effective option.

    Purpose: Lyso-thermosensitive liposomal doxorubicin (LTLD) consists of doxorubicin contained within a heat-sensitive liposome. When heated to ≥40°C, LTLD locally releases a high concentration of doxorubicin. We aimed to determine whether adding LTLD improves the efficacy of radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) lesions with a maximum diameter (dmax) of 3 to 7 cm.Experimental Design: The HEAT Study was a randomized, double-blind, dummy-controlled trial of RFA ± LTLD. The 701 enrolled patients had to have ≤4 unresectable HCC lesions, at least one of which had a dmax of 3 to 7 cm. The primary endpoint was progression-free survival (PFS) and a key secondary endpoint was overall survival (OS). Post hoc subset analyses investigated whether RFA duration was associated with efficacy.Results: The primary endpoint was not met; in intention-to-treat analysis, the PFS HR of RFA + LTLD versus RFA alone was 0.96 [95% confidence interval (CI), 0.79-1.18; P = 0.71], and the OS HR ratio was 0.95 (95% CI, 0.76-1.20; P = 0.67). Among 285 patients with a solitary HCC lesion who received ≥45 minutes RFA dwell time, the OS HR was 0.63 (95% CI, 0.41-0.96; P < 0.05) in favor of combination therapy. RFA + LTLD had reversible myelosuppression similar to free doxorubicin.Conclusions: Adding LTLD to RFA was safe but did not increase PFS or OS in the overall study population. However, consistent with LTLD's heat-based mechanism of action, subgroup analysis suggested that RFA + LTLD efficacy is improved when RFA dwell time for a solitary lesion ≥45 minutes.
