RESUMO

BACKGROUND: Our previous work indicated that the addition of lobaplatin to combined therapy with taxane and anthracycline can improve the pathological complete response rate of neoadjuvant therapy for triple-negative breast cancer (TNBC) and lengthen long-term survival significantly, but the therapeutic markers of this regimen are unclear. METHODS: Eighty-three patients who met the inclusion criteria were included in this post hoc analysis. We analyzed the association between platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) before neoadjuvant chemotherapy with the efficacy and prognosis after treatment with docetaxel, epirubicin, and lobaplatin neoadjuvant chemotherapy regimen. χ2 test and Cox regression were used to analyze the association between PLR and NLR with total pathologic complete response (tpCR), as well as the association between PLR and NLR with event-free survival (EFS) and overall survival (OS), respectively. RESULTS: The tpCR rate in the PLR- group was 49.0% (25/51), which was significantly higher than that in the PLR+ group (25.0% [8/32], P = .032). The tpCR rate in the NLR- group was 49.1% (26/53), which was significantly higher than that in the NLR+ group (23.3% [7/30], P = .024). The tpCR rate of the PLR-NLR- (PLR- and NLR-) group was 53.7% (22/41), which was significantly higher than that of the PLR+/NLR+ (PLR+ or/and NLR+) group (26.1% [11/42]; P = .012). EFS and OS in the NLR+ group were significantly shorter than those in the NLR- group (P = .028 for EFS; P = .047 for OS). Patients in the PLR-NLR- group had a longer EFS than those in the PLR+/NLR+ group (P = .002). CONCLUSION: PLR and NLR could be used to predict the efficacy of neoadjuvant therapy with the taxane, anthracycline, and lobaplatin regimen for patients with TNBC, as patients who had lower PLR and NLR values had a higher tpCR rate and a better long-term prognosis.

RESUMO

Ovarian cancer is the most lethal gynecological cancer type in the United States. The success of current chemotherapies is limited by chemoresistance and side effects. Targeted therapy is a promising future direction for cancer therapy. In the present study, the efficacy of co­targeting IL­6 and IL­8 in human ovarian cancer cells by bazedoxifene (Baze) + SCH527123 (SCH) treatment was examined. ELISA, cell viability, cell proliferation, cell migration, cell invasion, western blotting and peritoneal ovarian tumor mouse model analyses were performed to analyze the expression levels of IL­6 and IL­8, tumor growth, tumor migration and invasion, and the possible pathways of human ovarian cancer cell lines (SKOV3, CAOV3 and OVCAR3) and patient­derived OV75 ovarian cancer cells. Each cell line was treated by monotherapy or combination therapy. The results demonstrated that IL­6 and IL­8 were secreted by human ovarian cancer cell lines. Compared with the DMSO control, the combination of IL­6/glycoprotein 130 inhibitor Baze and IL­8 inhibitor SCH synergistically inhibited cell viability in ovarian cancer cells. Baze + SCH also inhibited cell migration and invasion, suppressed ovarian tumor growth and inhibited STAT3 and AKT phosphorylation, as well as survivin expression. Therefore, co­targeting the IL­6 and IL­8 signaling pathways may be an effective approach for ovarian cancer treatment.

RESUMO

BACKGROUND: 18F-fluciclovine is a synthetic amino acid positron emission tomography (PET) radiotracer that is approved for use in prostate cancer. In this clinical study, we characterised the kinetic model best describing the uptake of 18F-fluciclovine in breast cancer and assessed differences in tracer kinetics and static parameters for different breast cancer receptor subtypes and tumour grades. METHODS: Thirty-nine patients with pathologically proven breast cancer underwent 20-min dynamic PET/computed tomography imaging following the administration of 18F-fluciclovine. Uptake into primary breast tumours was evaluated using one- and two-tissue reversible compartmental kinetic models and static parameters. RESULTS: A reversible one-tissue compartment model was shown to best describe tracer uptake in breast cancer. No significant differences were seen in kinetic or static parameters for different tumour receptor subtypes or grades. Kinetic and static parameters showed a good correlation. CONCLUSIONS: 18F-fluciclovine has potential in the imaging of primary breast cancer, but kinetic analysis may not have additional value over static measures of tracer uptake. CLINICAL TRIAL REGISTRATION: NCT03036943.

RESUMO

OBJECTIVES: 18F-fluciclovine (fluciclovine) is an amino acid analog approved by the Food and Drug Administration for use as a radiotracer in positron emission tomography (PET) in men with biochemical recurrence of suspected prostate cancer. The purpose of this study was to investigate the initial institutional experience with 18F-fluciclovine in the evaluation of prostate cancer with biochemical recurrence. METHODS: This study was a retrospective review of 135 patients who underwent 18F-fluciclovine PET-computed tomography (PET-CT) at a single institution from August 2018 through January 2020. Prognostic information, including prostate-specific level antigen (PSA) at the time of diagnosis, initial risk, initial Gleason score, and initial stage, was reviewed as well as the PSA level at the time of the scan. The images were reviewed by two radiologists with fellowship training in nuclear medicine and additional training to interpret the fluciclovine studies. A minority of studies were reviewed by a third fellowship-trained radiologist under the guidance of the two nuclear medicine-trained radiologists. In cases with abnormal radiopharmaceutical uptake in lymph nodes, the short-axis dimension of the lymph node or largest lymph node with abnormal uptake was noted. If CT or bone scan was performed within 4 months of the 18F-fluciclovine PET-CT, findings on the alternate imaging were compared with the results of the 18F-fluciclovine PET-CT. RESULTS: Our institutional positivity rate was 75.6%, with 64 (67.4%) patients with metastatic disease and 71 (52.6%) patients with local recurrence detected by fluciclovine. As expected, the rate of positive examinations increased with increasing PSA values measured at the time of imaging (P < 0.001). Of the 54 patients with nodal disease, 35 had nonpathologically enlarged lymph nodes measuring <1 cm in maximum short-axis dimension. In more than half of the patients in this study, with conventional imaging, fluciclovine either discovered otherwise undetectable metastatic disease or suggested the presence of local recurrence. CONCLUSIONS: Our single-institution experience with 18F-fluciclovine PET-CT has the largest number of patients to date in the literature and demonstrates the ability of fluciclovine to help guide clinical management in the detection of early recurrent disease.

RESUMO

BACKGROUND: Cisplatin-based induction chemotherapy plus concurrent chemoradiotherapy in the treatment of patients with locoregionally advanced nasopharyngeal carcinoma has been recommended in the National Comprehensive Cancer Network Guidelines. However, cisplatin is associated with poor patient compliance and has notable side-effects. Lobaplatin, a third-generation platinum drug, has shown promising antitumour activity against several malignancies with less toxicity. In this study, we aimed to evaluate the efficacy of lobaplatin-based induction chemotherapy plus concurrent chemoradiotherapy over a cisplatin-based regimen in patients with locoregional, advanced nasopharyngeal carcinoma. METHODS: In this open-label, non-inferiority, randomised, controlled, phase 3 trial done at five hospitals in China, patients aged 18-60 years with previously untreated, non-keratinising stage III-IVB nasopharyngeal carcinoma; Karnofsky performance-status score of at least 70; and adequate haematological, renal, and hepatic function were randomly assigned (1:1) to receive intravenously either lobaplatin-based (lobaplatin 30 mg/m2 on days 1 and 22, and fluorouracil 800 mg/m2 on days 1-5 and 22-26 for two cycles) or cisplatin-based (cisplatin 100 mg/m2 on days 1 and 22, and fluorouracil 800 mg/m2 on days 1-5 and 22-26 for two cycles) induction chemotherapy, followed by concurrent lobaplatin-based (two cycles of intravenous lobaplatin 30 mg/m2 every 3 weeks plus intensity-modulated radiotherapy) or cisplatin-based (two cycles of intravenous cisplatin 100 mg/m2 every 3 weeks plus intensity-modulated radiotherapy) chemoradiotherapy. Total radiation doses of 68-70 Gy (for the sum of the volumes of the primary tumour and enlarged retropharyngeal nodes), 62-68 Gy (for the volume of clinically involved gross cervical lymph nodes), 60 Gy (for the high-risk target volume), and 54 Gy (for the low-risk target volume), were administered in 30-32 fractions, 5 days per week. Randomisation was done centrally at the clinical trial centre of Sun Yat-sen University Cancer Centre by means of computer-generated random number allocation with a block design (block size of four) stratified according to disease stage and treatment centre. Treatment assignment was known to both clinicians and patients. The primary endpoint was 5-year progression-free survival, analysed in both the intention-to-treat and per-protocol populations. If the upper limit of the 95% CI for the difference in 5-year progression-free survival between the lobaplatin-based and cisplatin-based groups did not exceed 10%, non-inferiority was met. Adverse events were analysed in all patients who received at least one cycle of induction chemotherapy. This trial is registered with the Chinese Clinical Trial Registry, ChiCTR-TRC-13003285 and is closed. FINDINGS: From June 7, 2013, to June 16, 2015, 515 patients were assessed for eligibility and 502 patients were enrolled: 252 were randomly assigned to the lobaplatin-based group and 250 to the cisplatin-based group. After a median follow-up of 75·3 months (IQR 69·9-81·1) in the intention-to-treat population, 5-year progression-free survival was 75·0% (95% CI 69·7-80·3) in the lobaplatin-based group and 75·5% (70·0 to 81·0) in the cisplatin-based group (hazard ratio [HR] 0·98, 95% CI 0·69-1·39; log-rank p=0·92), with a difference of 0·5% (95% CI -7·1 to 8·1; pnon-inferiority=0·0070). In the per-protocol population, the 5-year progression-free survival was 74·8% (95% CI 69·3 to 80·3) in the lobaplatin-based group and 76·4% (70·9 to 81·9) in the cisplatin-based group (HR 1·04, 95% CI 0·73 to 1·49; log-rank p=0·83), with a difference of 1·6% (-6·1 to 9·3; pnon-inferiority=0·016). 63 (25%) of 252 patients in the lobaplatin-based group and 63 (25%) of 250 patients in the cisplatin-based group had a progression-free survival event in the intention-to-treat population; 62 (25%) of 246 patients in the lobaplatin-based group and 58 (25%) of 237 patients in the cisplatin-based group had a progression-free survival event in the per-protocol population. The most common grade 3-4 adverse events were mucositis (102 [41%] of 252 in the lobaplatin-based group vs 99 [40%] of 249 in the cisplatin-based group), leucopenia (39 [16%] vs 56 [23%]), and neutropenia (25 [10%] vs 59 [24%]). No treatment-related deaths were reported. INTERPRETATION: Lobaplatin-based induction chemotherapy plus concurrent chemoradiotherapy resulted in non-inferior survival and fewer toxic effects than cisplatin-based therapy. The results of our trial indicate that lobaplatin-based induction chemotherapy plus concurrent chemoradiotherapy might be a promising alternative regimen to cisplatin-based treatment in patients with locoregional, advanced nasopharyngeal carcinoma.

RESUMO

WHAT IS KNOWN AND OBJECTIVE: To compare short-term therapeutic efficacies and related changes of serum markers from two chemotherapeutic regimes using lobaplatin or carboplatin in combination with paclitaxel in ovarian cancer patients after cytoreductive surgery. METHODS: 120 patients were recruited with pathologically confirmed ovarian cancer. Patients were equally and randomly divided into two groups receiving paclitaxel (PTX) with lobaplatin (LBP) or carboplatin (CBP, as control), respectively, 21 days as a cycle for 6 cycles. Follow-up was performed for 6 months post-treatment. The therapeutic efficacy, serum levels of CA125 (cancer antigen 125/ mucin 16) and HE4 (Human epididymis protein 4) as well as the quality of life were assessment before and after treatment. RESULTS: No significant difference in therapeutic efficacy was observed between the groups (P > .05). The response rates at 1, 3 and 6 months were 76.7%, 66.7% and 46.7% in the LBP group and 73.3%, 63.3% and 36.7% in the CPB group, respectively. At the end of chemotherapy, serum levels of HE4 and CA125 in both groups returned to normal. However, patients in the LBP group had significantly lower HE4 and CA125 levels than those in the CPB group when examined at 3 or 6 months after chemotherapy (P < .05). Moreover, at the end of follow-up, the quality-of-life score (QLQ-C30) of the LBP group was better than that of the CBP group with statistical significance (P < .05). WHAT IS NEW AND CONCLUSION: Both lobaplatin and carboplatin have decent anti-tumour efficacy to be involved in the standard platinum/paclitaxel-based chemotherapy against ovarian cancer. Lobaplatin, on the other hand, has demonstrated higher efficacy to control the progress of the disease yet less toxicity to warrant better patient quality of life.

RESUMO

Sibutramine is a non-selective serotonin-norepinephrine reuptake inhibitor orally administered for weight loss. In a previous study, we showed pharmacological mechanisms involved in the reduction of sperm quality and fertility of rats exposed for 30 days to this anorexigen in the light phase of the light-dark (l/d) cycle. It is already known that rodents are nightlife animals, with higher metabolic activity during the dark phase than in the light phase of the light-dark (l/d) cycle. Thus, the present study aimed to investigate whether the deleterious effects on reproductive parameters after sibutramine administration would be enhanced after a shorter period of exposure during the dark phase of the l/d cycle. For this, adult male Wistar rats were treated with sibutramine (10 mg/kg/d) or vehicle for 15 days during the dark phase of the l/d cycle. Sibutramine treatment decreased final body and reproductive organ weights, as well as serum testosterone levels. Sperm transit time through the epididymis was accelerated, and sperm concentration and motility were diminished in the sibutramine-exposed rats. The decrease in sperm concentration was also verified in the epididymal histological sections. In conclusion, the deleterious effects of sibutramine on reproductive parameters of male rats were enhanced when the exposure occurred in the dark phase of the l/d cycle, even after a short exposure duration. Our results reinforce the impact of timing on drug therapeutic action.

RESUMO

The aim of this prospective single-institution clinical trial (NCT02002455) was to evaluate the potential of advanced post-processing methods for 18F-Fluciclovine PET and multisequence multiparametric MRI in the prediction of prostate cancer (PCa) aggressiveness, defined by Gleason Grade Group (GGG). 21 patients with PCa underwent PET/CT, PET/MRI and MRI before prostatectomy. DWI was post-processed using kurtosis (ADCk, K), mono- (ADCm), and biexponential functions (f, Dp, Df) while Logan plots were used to calculate volume of distribution (VT). In total, 16 unique PET (VT, SUV) and MRI derived quantitative parameters were evaluated. Univariate and multivariate analysis were carried out to estimate the potential of the quantitative parameters and their combinations to predict GGG 1 vs >1, using logistic regression with a nested leave-pair out cross validation (LPOCV) scheme and recursive feature elimination technique applied for feature selection. The second order rotating frame imaging (RAFF), monoexponential and kurtosis derived parameters had LPOCV AUC in the range of 0.72 to 0.92 while the corresponding value for VT was 0.85. The best performance for GGG prediction was achieved by K parameter of kurtosis function followed by quantitative parameters based on DWI, RAFF and 18F-FACBC PET. No major improvement was achieved using parameter combinations with or without feature selection. Addition of 18F-FACBC PET derived parameters (VT, SUV) to DWI and RAFF derived parameters did not improve LPOCV AUC.

RESUMO

Cisplatin is the most commonly used chemotherapeutic drug for nasopharyngeal carcinoma (NPC), while its side effects are often intolerable. Lobaplatin, as an effective third-generation platinum with fewer adverse reactions and less platinum cross-resistance, has been considered as a good alternative to cisplatin after cisplatin's failure (relapse or metastasis) in the treatment of NPC. However, the anti-NPC mechanism of lobaplatin remains largely unknown. In present study, 50% inhibiting concentration (IC50) of lobaplatin for NPC cells is found to be similar to that of cisplatin. 10 µM and 20 µM lobaplatin caused obvious gasdermin-E (GSDME)-mediated pyroptosis by activating caspase-3. Moreover, we found lobaplatin induced proteasomal degradation of cell inhibitor of apoptosis protein-1/2 (cIAP1/2). And these pyroptotic phenomena could be suppressed by the recovery of cIAP1/2, suggesting that cIAP1/2 are critical in lobaplatin-induced pyroptosis. Further inhibition of cIAP1/2 by birinapant (an antagonist of cIAP1/2) dramatically enhanced pyroptosis induced by lobaplatin in vitro and in vivo, which was consistent with the combination with cisplatin. Importantly, this synergistic pyroptotic effect were suppressed by the inhibition of Ripoptosome (RIPK1/Caspase-8/FADD), reactive oxygen species (ROS) and caspase-3 cleavage, and were independent of phosphorylation of JNK and NF-κB signal. Our data reveal that cIAP1/2 play important roles in lobaplatin-induced NPC cell pyroptosis, and this anti-NPC effect can be significantly potentiated by cIAP1/2 antagonist birinapant through regulating the formation of Ripoptosome and the generation of ROS. These study provides a possibility to further reduce the platinum-related adverse events and chemoresistance of lobaplatin while maintaining satisfactory anti-NPC efficacy.

RESUMO

Here, we report a case of a 36-year-old female patient with metastatic non-small cell lung cancer (NSCLC) harboring EGFR-ANXA2 and EGFR-RAD51 double fusion mutations with BRCA2 (nonsense mutation of exon 11) and ATR mutations (Exon 44 variable shear mutation) identified by next generation sequencing (NGS). The efficacy was significantly improved after lobaplatin combined with pemetrexed, temozolomide and bevacizumab. This is the first report of a novel mutation type EGFR-ANXA2, as well as double EGFR fusion mutations in advanced lung adenocarcinoma. Furthermore, platinum-based chemotherapy plus bevacizumab rather than targeted therapy showed favorable effects in this patient, providing a novel therapeutic conception for patients, even with multidriver mutations.

RESUMO

BACKGROUND: This study evaluated the efficacy and safety of docetaxel combined with lobaplatin, relative to docetaxel combined with gemcitabine, for treating patients with recurrent metastatic breast cancer (rMBC). METHODS: Patients with rMBC received ≥2 cycles (21 days each) of either docetaxel and lobaplatin (DL; n = 21), or docetaxel and gemcitabine (DG; n = 22). On day 1 of each cycle, all patients were given 75 mg/m intravenous docetaxel. Patients in DL and DG were also given, respectively, 35 mg/m intravenous lobaplatin (day 2) or 1000 mg/m intravenous gemcitabine (days 1, 8). RESULTS: Five (11.6%) and 16 (37.2%) patients achieved complete remission and partial response, respectively; rates of response and disease control were 48.8%. The response rates of the groups were comparable (47.6%, 50.0%). The median survival times after relapse and metastasis of the DL group (18 months) were significantly less than that of the DG group (25 months). Median progression-free survivals after relapse and metastasis were similar (12 cf. 14 months). The main toxic side reaction was grade 2, with no treatment-related deaths. Rates of the following were comparable between DG and DL: grade 3 or 4 white blood cells (23.8%, 31.8%) and digestive tract toxicity (4.8%, 4.5%); neutropenia (28.6%, 22.7%); anemia (4.8%, nil); and thrombocytopenia (19.0%, 13.6%). Other toxicities included hepatic toxicity, myalgia, infection, and fatigue. CONCLUSIONS: Both the DL and DG regimens were associated with encouraging benefits, while treatment-related toxicity was manageable. Therefore, these regimens are effective options for treatment of rMBC.

RESUMO

BACKGROUND: National Comprehensive Cancer Network guidelines consider 18F-fluciclovine PET-CT for prostate cancer biochemical recurrence localisation after radical prostatectomy, whereas European Association of Urology guidelines recommend prostate-specific membrane antigen (PSMA) PET-CT. To the best of our knowledge, no prospective head-to-head comparison between these tests has been done so far. The aim of this study was to compare prospectively paired 18F-fluciclovine and PSMA PET-CT scans for localising biochemical recurrence of prostate cancer after radical prostatectomy in patients with low prostate-specific antigen (PSA) concentrations (<2·0 ng/mL). METHODS: This was a prospective, single-centre, open-label, single-arm comparative study done at University of California Los Angeles (Los Angeles, CA, USA). Patients older than 18 years of age with prostate cancer biochemical recurrence after radical prostatectomy and PSA levels ranging from 0·2 to 2·0 ng/mL without any prior salvage therapy and with a Karnofsky performance status of at least 50 were eligible. Patients underwent 18F-fluciclovine (reference test) and PSMA (index test) PET-CT scans within 15 days. Detection rate of biochemical recurrence at the patient level and by anatomical region was the primary endpoint. A statistical power analysis demonstrated that a sample size of 50 patients was needed to show a 22% difference in detection rates in favour of PSMA (test for superiority). Each PET scan was interpreted by three independent masked readers and a consensus majority interpretation was generated (two vs one) to determine positive findings. This study is registered with ClinicalTrials.gov, number NCT02940262, and is complete. FINDINGS: Between Feb 26, 2018, and Sept 20, 2018, 143 patients were screened for eligibility, of whom 50 patients were enrolled into the study. Median follow-up was 8 months (IQR 7-9). The primary endpoint was met; detection rates were significantly lower with 18F-fluciclovine PET-CT (13 [26%; 95% CI 15-40] of 50) than with PSMA PET-CT (28 [56%; 41-70] of 50), with an odds ratio (OR) of 4·8 (95% CI 1·6-19·2; p=0·0026) at the patient level; in the subanalysis of the pelvic nodes region (four [8%; 2-19] with 18F-fluciclovine vs 15 [30%; 18-45] with PSMA PET-CT; OR 12·0 [1·8-513·0], p=0·0034); and in the subanalysis of any extrapelvic lesions (none [0%; 0-6] vs eight [16%; 7-29]; OR non-estimable [95% CI non-estimable], p=0·0078). INTERPRETATION: With higher detection rates, PSMA should be the PET tracer of choice when PET-CT imaging is considered for subsequent treatment management decisions in patients with prostate cancer and biochemical recurrence after radical prostatectomy and low PSA concentrations (≤2·0 ng/mL). Further research is needed to investigate whether higher detection rates translate into improved oncological outcomes. FUNDING: None.

RESUMO

BACKGROUND: Compared with single-drug TACE, our previous phase III study demonstrated that triple-drug transarterial chemoembolization (TACE) prolonged overall survival (OS) in patients with unresectable hepatocellular carcinoma (HCC). The aim of this study was to find which patients can benefit from the triple drugs TACE compared with single-drug TACE. METHODS: Patients in the triple-drug TACE arm received sponge embolization and emulsions composed of 50 mg epirubicin, 50 mg lobaplatin, 6 mg mitomycin C, and lipiodol, while patients in the single-drug TACE arm received sponge embolization and emulsions composed of 50 mg epirubicin and lipiodol. From July 2007 to November 2009, 244 patients (224 men and 20 women; age ranged from 21 to 75 years) from our phase III study formed the initial cohort. From January 2010 to June 2015, external validation cohort was composed of 449 patients (411 men and 38 women; age ranged from 18 to 75 years) from another institution. The validation cohort after propensity score matching (PSM) (n = 374) was analyzed. Cox proportional hazard model was used to evaluate the interaction term between treatments for each subgroup. This retrospective study was approved by the institutional review board at each center. RESULTS: No difference was observed in the baseline characteristic of three cohorts. This exploratory analysis showed that triple-drug TACE brought a survival benefit in the initial cohort, validation cohort (before PSM), and validation cohort (after PSM) compared with single-drug TACE. The outcomes of three cohorts all showed that a significantly greater OS triple-drug chemotherapy benefit versus single-drug chemotherapy was seen in patients with large tumors (larger than 10 cm) while no survival difference was seen in patients with small tumors (10 cm or smaller). CONCLUSIONS: Triple-drug TACE seems to benefit patients with HCC larger than 10 cm in particular compared with single-drug TACE.

RESUMO

PURPOSE: This phase II, multicenter, single arm clinical study was first performed to evaluate the therapeutic efficacy and safety of the regimen-a combination of lobaplatin (LBP) and etoposide (VP-16)-and investigate the pharmacokinetics of LBP in Chinese men older than 65 years with extensive-stage small cell lung cancer (SCLC). METHODS: Patients older than 65 were treated with the combination of LBP and VP-16 for 4-6 cycles through intravenous drip. The initial dose of VP-16 was 100 mg/m2/day for d1-d3 in each 21-day cycle, while LBP was administrated for d1 in each cycle based on creatinine clearance (Ccr), 20 mg/m2 for Ccr < 60 mL/min; 25 mg/m2 for 60 ≤ Ccr < 80 mL/min and 30 mg/m2 for Ccr ≥ 80 mL/min. Efficacy, safety and pharmacokinetics were evaluated to confirm the therapeutic effect. RESULTS: Thirteen elderly patients were enrolled and three patients were discontinued. The median progress-free survival was 129 days and the median overall survival was 238 days, which caused a significantly prolonged survival rate of 38.5% and a higher disease control rate of 80%. Most frequent adverse events were mild to moderate containing leukopenia, neutropenia, anemia, nausea and anorexia. Pharmacokinetic analysis revealed that there is no significant difference between LP-D1 and LP-D2 at the same dosage level. With the dosage increasing, the elimination clearance showed a slowing tendency, especially for 30 mg/m2 group. CONCLUSIONS: LBP (20, 25, 30 mg/m2) in combination with VP-16 (100 mg/m2) could inhibit the elderly SCLC disease process, prolong their survival time and reduce adverse reactions via preliminary assessment and provide guidance for further investigation.

RESUMO

PURPOSE: To explore the safety and feasibility of intraoperative, intraperitoneal perfusion chemotherapy with lobaplatin for colorectal cancer (CRC). METHODS: From November 1, 2016 to January 15, 2017, a total of 100 patients with CRC in Cancer Hospital, Chinese Academy of Medical Science and Peking Union Medical College, who had undergone radical surgery, were randomized into two groups as follows: the lobaplatin group (50 patients) and the control group (50 patients). The time of recovery of postoperative intestinal functions, hematotoxicity, hepatic-renal toxicity, and postoperative complications were observed and analyzed, with the goal of exploring the safety and feasibility of the drug administration. RESULTS: The time to first gas exhaust in lobaplatin and the control group was 3.08 days and 3.20 days, respectively (p=0.392). The time of defecation in lobaplatin and the control group was 4.38 days and 4.50 days, respectively (p=0.524). There was no statistically significant difference between them in terms of the time of gas exhaust and defecation. One case with intra-abdominal hemorrhage, 1 case with anastomotic leakage, 3 cases with incision complication, 1 case with adhesive intestinal obstruction, and 1 case with pulmonary infection occurred in lobaplatin group compared to 1 case with anastomotic bleeding, 1 case with anastomotic leakage, 2 cases with incision complication, 2 cases with adhesive intestinal obstruction, 2 cases with pulmonary infection, and 1 case with lymphatic fistulas occurred in control group. There was no statistically significant difference between the groups in terms of the total incidence of postoperative complications (p=0.790). No statistically significant difference was observed between the groups in terms of leukocyte and platelet levels on the first, third, and fifth postoperative day. There was also no statistically significant difference in terms of platelet level 2 weeks after surgery. Both the lobaplatin and control group had 2 cases with postoperative abnormal hepatic-renal function. A total of 6 cases in the lobaplatin group and 7 cases in the control group developed gastrointestinal reactions, showing no statistically significant difference (p=0.766). CONCLUSION: Intraoperative intraperitoneal perfusion chemotherapy with lobaplatin showed no effect on short-term recovery in patients with CRC.

RESUMO

BACKGROUND: A retrospective study was conducted to assess the efficacy and toxicity of lobaplatin-etoposide (EL) chemotherapy for small cell lung cancer (SCLC). METHODS: The clinical data of 50 patients treated in our department from May 2014 to March 2018 were obtained. Untreated patients with SCLC administered LBP intravenously (IV) at 30 mg/m2 on day 1 and etoposide IV at 100 mg/m2 on days 1, 2, and 3 were enrolled. The treatment was cycled every 21 days. RESULTS: The median overall and progression-free survival rates of the 50 patients were 11.67 (range: 7.30-16.04) and 6.8 (range: 5.25-8.35) months, respectively, with an overall response rate of 66% and a disease control rate of 90%. The most frequent drug-related adverse effects were leukopenia and neutropenia, and no grade 3/4 hepatotoxicity or nephrotoxicity was observed. CONCLUSION: These results indicate that LBP-containing chemotherapy is effective and tolerable for SCLC in terms of response and survival.

RESUMO

PURPOSE: The prospective, multicenter LOCATE (F Fluciclovine [FACBC] PET/CT in Patients with Rising PSA after Initial Prostate Cancer Treatment) trial assessed the impact of positron emission tomography/computerized tomography with F-fluciclovine on treatment plans in patients with biochemical recurrence of prostate cancer after primary therapy with curative intent. MATERIALS AND METHODS: Men who had undergone curative intent treatment of histologically confirmed prostate cancer but who were suspected to have recurrence based on rising prostate specific antigen levels were enrolled prospectively. Each man had negative or equivocal findings on standard of care imaging. F-fluciclovine positron emission tomography/computerized tomography was performed according to standardized protocols. Treating physicians completed a questionnaire regarding the patient treatment plan before and after scanning, recording changes to the treatment modality (eg salvage radiotherapy to systemic androgen deprivation therapy) as major and changes in a modality (eg modified radiotherapy fields) as other. RESULTS: Between June 2016 and May 2017, 213 evaluable patients with a median age of 67 years and median prostate specific antigen 1.00 ng/ml were enrolled in study. F-fluciclovine avid lesions were detected in 122 of the 213 patients (57%). Overall 126 of the 213 patients (59%) had a change in management after the scan, which were major in 98 of 126 (78%) and in 88 (70%) were informed by positive positron emission tomography/computerized tomography findings. The most frequent major changes were from salvage or noncurative systemic therapy to watchful waiting (32 of 126 cases or 25%), from noncurative systemic therapy to salvage therapy (30 of 126 or 24%) and from salvage therapy to noncurative systemic therapy (11 of 126 or 9%). CONCLUSIONS: F-fluciclovine positron emission tomography/computerized tomography detected 1 or more recurrence sites in the majority of men with biochemical recurrence, frequently resulting in major changes to management plans. Future studies will be planned to determine whether a management change leads to improved outcomes.

RESUMO

To observe and analyze the therapeutic effect of combinated application of lobaplatin and irinotecan in treating recurrant small cell lung cancer. The 140 patients who were treated in our hospital for recurrant small cell lung cancer were selected as research objects. All selected patients were subjected to combined application of obaplatin and irinotecan, the total therapeutic effect was observed, and the adverse reactions occurring during treatment were recorded. Through observing the total treatment effective ratio of 140 patients recurrant small cell lung cancer, the number of complete remission cases, number of partial remission cases, number of stable disease cases, and number of disease progression cases were 40(28.57%), 28(20.00%), 30(21.43%), 42(30.00%), respectively, with total effective ratio of 48.57%. The average time to progression (TTP) was (4.5±0.8) months, average overall survival (OS) was (7.6±1.2) months. The toxic and adverse effects mainly included hematological toxicity and gastrointestinal adverse reaction, such as leukocyte reduction, neutrophil reduction, thrombocytopenia, decreased hemoglobin, nausea and vomiting, diarrhea. No toxicity-related death occurred. In treatment of patients with recurrant small cell lung cancer, the combined application of lobaplatin and irinotecan can achieve great results, which is a safe and reliable way of treatment.
