A 40-year-old woman presented with ocular discomfort in both eyes that had persisted for several months. Six months ago, she had undergone a bilateral nasal and temporal conjunctivectomy using a bare scleral technique followed by a postoperative application of 0.02% mitomycin C (MMC) to treat her chronic hyperemic conjunctiva for cosmesis. Slit-lamp examination revealed that the patient had bilateral nasal and temporal scleral thinning, and a calcified plaque on her nasal conjunctiva. There was no episcleral tissue present around the wound area, and it was difficult to detect any normal conjunctival tissue in the adjacent area for covering the lesion. We believe that performing an aggressive conjunctival excision procedure followed with MMC application for cosmetic enhancement may be disastrous in certain cases.

Treating patients undergoing chemotherapy who display findings of liver toxicity, requires a solid understanding of these medications. It is important for any clinician to have an index of suspicion for liver toxicity and be able to recognize it, even on imaging. Cancer chemotherapy has evolved, and newer medications that target cell biology have a different pattern of liver toxicity and may differ from the more traditional cytotoxic agents. There are several hepatic conditions that can result and keen clinical as well as radiographic recognition are paramount. Conditions such as sinusoidal obstructive syndrome, steatosis, and pseudocirrhosis are more commonly associated with chemotherapy. These conditions can display clinical signs of acute hepatitis, liver cirrhosis, and even liver failure. It is important to anticipate and recognize these adverse reactions and thus appropriate clinical action can be taken. Often times, patients with these liver manifestations can be managed with supportive therapies, and liver toxicity may resolve after discontinuation of chemotherapy.

OBJECTIVETo determine the interaction between 2450-MHz microwaves (MW) radiation and mitomycin C (MMC).

METHODSThe synergistic genotoxic effects of low-intensity 2450-MHz microwave and MMC on human lymphocytes were studied using single cell gel electrophoresis (SCGE) assay (comet assay) and cytokinesis-blocked micronucleus (CBMN) test in vitro. The whole blood cells from a male donor and a female donor were either only exposed to 2450-MHz microwaves (5.0 mW/cm2) for 2 h or only exposed to MMC (0.0125 microgram/mL, 0.025 microgram/mL and 0.1 microgram/mL) for 24 h; and the samples were exposed to MMC for 24 h after exposure to MW for 2 h.

RESULTSIn the comet assay, the comet lengths (29.1 microns and 25.9 microns) of MW were not significantly longer than those (26.3 microns and 24.1 microns) of controls (P > 0.05). The comet lengths (57.4 microns, 68.9 microns, 91.4 microns, 150.6 microns, 71.7 microns, 100.1 microns, 145.1 microns) of 4 MMC groups were significantly longer than those of controls (P < 0.01). The comet lengths (59.1 microns, 92.3 microns, 124.5 microns, 182.7 microns and 57.4 microns, 85.5 microns, 137.5 microns, 178.3 microns) of 4 MW plus MMC groups were significantly longer than those of controls too (P < 0.01). The comet lengths of MW plus MMC groups were significantly longer than those of the corresponding MMC doses (P < 0.05 or P < 0.01) when the doses of MMC were > or = 0.025 microgram/mL. In the CBMN, the micronucleated cell (MNC) rates of MW were 5@1000 and 6@1000, which showed no difference compared with those (4@1000 and 4@1000) of controls (P > 0.05). The MNC rates of 4 MMC groups were 8@1000, 9@1000, 14@1000, 23@1000 and 8@1000, 8@1000, 16@1000, 30@1000 respectively. When the doses of MMC were > or = 0.05 microgram/mL, MNC rates of MMC were higher than those of controls (P < 0.05). MNC rates of 4 MW plus MMC groups were 12@1000, 13@1000, 20@1000, 32@1000 and 8@1000, 9@1000, 23@1000, 40@1000. When the doses of MMC were > or = 0.05 microgram/mL, MNC rates of MW plus MMC groups were much higher than those of controls (P < 0.01). MNC rates of 4 MW plus MMC groups were not significantly higher than those of the corresponding MMC doses.

CONCLUSIONThe low-intensity 2450-MHz microwave radiation can not induce DNA and chromosome damage, but can increase DNA damage effect induced by MMC in comet assay.

OBJECTIVETo investigate the toxicity attenuation and efficacy potentiation effects of Sijunzi decoction (SJZD) on bladder carcinoma treated by chemotherapy in mice.

METHODST739 mice were randomly divided into 8 groups after subcutaneous inoculation of bladder carcinoma cells, the control group (A); two mitomycin C (MMC) group, treated with MMC of routine dosage (B) and low-dosage (C) respectively; three SJZD groups, treated with SJZD of high (D), medium (E) and low-dosage (F) respectively; and two combined treatment groups, treated with SJZD of high-dosage + MMC of routine dosage(G) and SJZD of high-dosage + MMC of low-dosage(H). The medication was begun at 24 hrs after inoculation. The tumor inhibitory rate, activity of peritoneal macrophages after 14 days of treatment and change of peripheral white blood cells after 7 days of treatment were determined and the survival time of mice was observed.

RESULTSThe survival time of mice in Group D was significantly higher than that in Group A (P < 0.05), while those in Group E and F showed insignificant difference as compared with those in Group A (P > 0.05). The highest tumor inhibitory rate was shown in Group B, but the survival time in that group showed no significant difference as compared to those in Group A (P > 0.05). The longest survival time (32.7 +/- 1.3 days) was shown in Group H, which was obviously different to that in other groups (P < 0.05). And the leukocyte counts and macrophage activity in Group H were better than those in Group B, C and G (P < 0.05), except that the tumor inhibitory rate was significantly lower than that in Group B, C and G (P < 0.05).

CONCLUSIONCombined chemotherapy of SJZD with low dosage MMC has definite effect in inhibiting tumor growth in mice with bladder carcinoma, displaying special effects of toxicity attenuation and efficacy potentiation.

Objective: To analyze the value of 3-dimensional speckle tracking echocardiograghy (3D-STE) derived strain parameters on the detection of subclinical myocardial deformation alterations in patients with lymphoma treated with anthracycline agents. Methods: This study was a retrospective study. A total of 37 patients with newly diagnosed diffuse large B cell non-Hodgkin lymphoma between December 2012 and December 2014 in Cancer Center, Fudan university were included. 3D-STE strain measurements were performed at baseline (T0),after the completion of two therapy circles (T1) and at the end of anthracycline regimen chemotherapy (Te). Echocardiography images were analyzed on the TTA workstation, and the indexes included left atrial minimum volume (LAVmin), left atrial emptying index (LAEF), left atrial active emptying index (LAAEF), as well as the left ventricular global longitudinal strain (LVGLS), left ventricular global circumferential strain (LVGCS), left atrial global longitudinal strain (LAGLS). The overall left atrioventricular longitudinal strain (LAVGLS) was calculated, which was the sum of the absolute values of LVGLS and LAGLS. The changes of left ventricular strain indexes measured by 3D-STE at different time points of patients were evaluated. Results: Thirty-seven patients with DLBCL, aged (48.3±12.1)years, including 23 males (63.9%), were enrolled. Compared with baseline, LVGLS (T1: (-18.63±4.73)% vs. (-22.13±4.40)%, P=0.001; Te:(-18.26±4.64)% vs. (-22.13±4.40)%, P<0.001), LAGLS (T1: (20.41±5.56)% vs. (23.98±5.59)%, P=0.003; Te: (17.60±3.96)% vs. (23.98±5.59)%, P<0.001) and LAVGLS (T1: (39.05±7.60)% vs. (46.11±7.77)%, P<0.001; Te: (40.34±8.55)% vs. (46.11±7.77)%, P<0.001) were all deteriorated at the T1 and Te. While LVGCS ((-21.98±5.82)% vs. (-26.15±7.51)%, P=0.010), LAVmin ((23.93±7.29)ml vs. (20.33±7.03)ml, P=0.029), LAEF ((28.94±11.16)% vs. (35.79±11.12)%, P=0.002) and LAAEF ((11.93±10.00)% vs. (18.10±9.96)%, P=0.013) were decreased only until Te. Conclusions: 3D-STE strain measurements could detect early myocaridial function alteration in patients receiving anthracycline regimen chemotherapy, thus may provide a novel approach to monitor anthracycline caused myocardial toxicity.

In order to assess the effect of long-term versus short-term intravesical chemotherapy in preventing the recurrence of patients with non-muscle-invasive bladder cancer, we searched several databases with words as mesh terms and free text words to find all eligible randomized clinical trials (RCTs) for the comparison of the two strategies of instillation durations. "Observed-Expected events research (O-E)" and "Variance (V)" for calculating hazard ratio (HR) were used in Revman 5.2 software recommended by Cochrane Collabration for data analysis. Sensitivity and subgroup analysis were selected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were included in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI (0.89, 1.11), P=0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI (0.69, 1.00), P=0.05]. But patients were not suitable to receive long-term instillations with epirubicin (EPI) [HR=1.01, 95% CI (0.91, 1.13), P=0.78]. The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI (0.66, 1.39), P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.

OBJECTIVETo investigate the efficiency and safety of different regimens by intravesical instillation of epirubicin, a derivative of adriamycin, for the prevention of primary superficial bladder carcinoma from recurrence.

METHODSNinety patients supplemented with intravesical epirubicin instillation after operation were randomly divided into three groups: Group A--80 mg in one dose; Group B--repeated epirubicin 40 mg q wk x 4-8 sessions followed by q month to the end of the second year; or Group C--50 mg q month to the same duration. All patients were followed up for two years by observing the recurrence rates and side effects.

RESULTSThe recurrence rate of groups A, B and C at one year was 16.7%, 13.3% and 16.7%, respectively, without any significant difference observed. However, it was 50.0%, 36.7% and 36.7% at two years, at which time the recurrence rate of group A was significantly higher than those of groups B and C. The side effects rate was 23.3%, 40.0% and 33.3% for groups A, B and C, respectively. The more instillations the patients had, the more severe side effects were.

CONCLUSIONEarly postoperative single high dose intravesical instillation of epirubicin combined with repeated lower doses of the same drug every month may be an efficient and safe regimen to prevent the primary superficial bladder carcinoma from recurrence.

OBJECTIVETo study relationship between daunorubicin (DNR) pharmacokinetics and efficacy and toxicity in children with acute leukemia.

METHODS(1) The concentration of DNR in plasma of children with acute leukemia was determined by high performance liquid chromatography (HPLC)-fluorescence detection method. Plasma was sampled frequently from the start of the infusion till the end of 24 h. DNR pharmacokinetics was studied by determination of the concentrations. (2) Efficacy and toxicity were monitored in each period after chemotherapy. Laboratory studies included examination of bone marrow, white blood cell count, electrocardiogram, echocardiogram, myocardial enzymogram, the liver and kidney function.

RESULTS(1) DNR was eliminated from plasma in a two-compartment manner. The maximum concentration was seen 1 - 3 h after infusion. Cmax was 63.50 microg/L. Tmax was 1.45 h. The concentration decreased quickly to a low level of about 11.52 microg/L from the end of 2 hours infusion. There was a large inter-individual difference in pharmacokinetic parameters of DNR. The difference of CL was 9-fold, AUC was 8-fold, Cmax was 5-fold. (2) CL of male patients [57.99 L/(h.m(2))] was significantly lower than that of female patients [93.71 L/(h.m(2))] (P < 0.05). Tmax of children older than 6 years was 1.1 h, and that of children younger than 6 years was 1.8 h (P < 0.05); Cmax of children older than 6 years was 90.77 microg/L, younger than 6 years was 57.44 microg/L (P < 0.05).

CONCLUSION(1) There is a large inter-individual difference in pharmacokinetic parameters of DNR in children. It may predict individual variety of efficacy and toxicity. Therapeutic drug monitoring is important. (2) Male patients and children older than 6 years had a higher bioavailability and lower metabolism, toxicity may easily occur in such children, therefore they may need lower dose.

OBJECTIVETo evaluate the efficacy and safety of IDA (Haizheng Parmacy, China) in the treatment of acute leukemia.

METHODSA multi-institutional single-blind randomized controlled clinical trial was carried out. A total of 155 newly diagnosed patients with AML and ALL were enrolled. The patients were randomly divided into two groups, one was given IDA (n = 77) and the other given zevodas (Pharnacia & Upjohn, n = 78) for comparison.

RESULTSAll the patients enrolled in this trial were eligible for assessment of side effects, and 129 patients for evaluation of overall response rate. In patients treated with IDA vs zevodas, the overall response rate (OR) was 78.1% vs 76.9%, CR was 68.8% vs 67.7%; in AML patients, OR was 82.4% vs 71.8%, and CR was 76.5% vs 64.1%; in ALL patients, OR was 80.0% vs 81.8%, and CR was 68.0% vs 68.2%. There was no sitatistically significant difference in hematologic and non-hematologic toxicities between the two groups.

CONCLUSIONThe efficacy of IDA in the treatment of acute leukemia is comparable to that of zevodas. Both have similar toxic side effects.
