OBJECTIVETo evaluate the short-term efficacy and safety of neoadjuvant synchronous chemoradiotherapy (paclitaxel plus carboplatin regimen) in stage III adenocarcinoma of esophagogastric junction (AEG).

METHODSForty cases clinically diagnosed as stage III AEG were prospectively enrolled at the Department of Gastrointestinal Oncology Surgery, the First Affiliated Hospital of Hebei North University from December 2014 to November 2017 and then were randomly divided into paclitaxel plus carboplatin combined with synchronous radiotherapy group(neoadjuvant group) and direct operation group. Inclusion criteria was as follows:(1) AEG was diagnosed by gastroscopic biopsy and III stage was confirmed by ultrasound endoscopy and spiral CT;(2) physical strength score ≥70, and age ≤75 years old; (3) no contraindications of chemoradiotherapy and operation. Exclusion criteria was as follows:(1) patients voluntarily withdrew or refused the treatment;(2) occurrence of severe anaphylaxis; (3) uncontrollable events happened during treatment and treatment was unable to continue;(4) tumor developed obviously during treatment. Preoperative neoadjuvant synchronous chemoradiotherapy used TP regimen: paclitaxel 80 mg/m², drug concentration-time area under curve of carboplatin= 1.5 mg×ml⁻¹×min⁻¹, once per week for 9 weeks; radiotherapy began at the second week, 40 Gy/20 F, completed within 4 weeks. Operative procedure of both groups was radical resection of cardiac cancer(D2). Postoperative chemotherapy regimen was oral Tegafur(Gimeracil and Oteracil potassium). The side effects, diet situation, change of gastroscopic image after treatment in patients of neoadjuvant group were observed and efficacy evaluation of chemotherapy was performed according to solid tumor efficacy evaluation criteria of US National Cancer Institute. Operation-associated parameters, including R0 resection rate, lymph node metastasis, operative mortality and postoperative complications, were compared between two groups.

RESULTSThere were no significant differences in baseline information between the two group (all P>0.05). One case in neoadjuvant group was excluded because of perforation at lesion site 7 weeks after chemotherapy. The side effects of 19 cases in neoadjuvant group were mainly alopecia (100%) and marrow inhibition (68.4%), while 3-4 degree side effects were alopecia(8/19,42.1%), leukopenia (3/19, 15.8%) and neutropenia(3/19, 15.8%). Complete remission was observed in 4 cases; partial remission was observed in 13 cases and stable disease in 2 cases, with an objective response rate of 89.5% and a disease control rate of 100%. Before neoadjuvant chemotherapy, 16 cases were difficult to take liquid diet and 3 cases received liquid diet only, while after 12 weeks of neoadjuvant chemotherapy, all the 19 cases received normal diet. Besides, after neoadjuvant chemotherapy, gastroscopic examination showed close healing of cardiac ulcer, disappearance of swelling, and renewal of normal mucosa. Compared to direct operation group, neoadjuvant group had less number of positive lymph node (4.9±3.6 vs. 8.8±2.8, P<0.05) and higher R0 resection rate (94.7% vs. 50.0%, P<0.05). Total number of harvested lymph node was not significantly different between two groups (19.1±2.5 vs. 18.6±7.0, t=0.326, P=0.746). There was no surgical death in either group. One case in direct operation group developed postoperative inflammatory obstruction. No associated complication was found in neoadjuvant group.

CONCLUSIONPaclitaxel plus carboplatin combined with synchronous radiotherapy can elevate the R0 resection rate of patients with stage III esophagogastric junction adenocarcinoma, without increasing operative mortality and postoperative complications.

OBJECTIVETo evaluate the cytotoxic effects of ampelopsin sodium (Amp-Na) and carboplatin (CBP) used alone or in combination on human non-small cell lung cancer (NSCLC) cells SPC-A1 in vitro and its related mechanism.

METHODSCytotoxic effects were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays. The synergistic effects of the drugs were calculated with coefficient of drug interaction (CDI). Cell cycle was determined by flow cytometry (FCM). The levels of p53, p21, cyclinE, cyclinD1, and phosphorylated cyclin-dependent kinase-2 (p-CDK2) were evaluated by Western blot.

RESULTSAmp-Na (6.25-200 μg/mL) and CBP (3.13-100 μg/mL) alone exhibited prominent cytotoxic activity in a concentration-dependent manner on SPC-A1 cells with 50% inhibitive concentration values of 57.07±14.46 and 34.97±6.30 μg/mL, respectively. Drug combinations were associated with significantly higher cytotoxic effects than each drug alone (P<0.05 or 0.01). The CDI analysis confirmed the synergy of Amp-Na and CBP on inhibiting cancer cell viability across a wide concentration range (CDI <1). FCM and Western blot showed that synergistic cytotoxic effects of Amp-Na and CBP were related to Garrested which mainlym ediated by p 21 through the inhibition of CDK2 activity independent of the p53 tumor suppressor pathway.

CONCLUSIONSAmp-Na exhibits anticancer activities and enhances the antitumor activities of CBP through up-regulation of p21 and inhibition of CDK2 activity in human NSCLC cells SPC-A1. These results suggest that Amp-Na may be applied to enhance the anticancer action of CBP.

OBJECTIVETo explore the safety and efficacy of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in preventing chemotherapy-induced neutropenia in patients with breast cancer and non-small cell lung cancer (NSCLC), and to provide the basis for clinical application.

METHODSAccording to the principle of open-label, randomized, parallel-group controlled clinical trial, all patients were randomized by 1∶1∶1 into three groups to receive PEG-rhG-CSF 100 μg/kg, PEG-rhG-CSF 6 mg, or rhG-CSF 5 μg/kg, respectively. The patients with breast cancer received two chemotherapy cycles, and the NSCLC patients received 1-2 cycles of chemotherapy according to their condition. All patients were treated with the combination chemotherapy of TAC (docetaxel+ epirubicin+ cyclophosphamide) or TA (docetaxel+ epirubicin), or the chemotherapy of docetaxel combined with carboplatin, with a 21 day cycle.

RESULTSThe duration of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg and PEG-rhG-CSF 6 mg groups were similar with that in the rhG-CSF 5 μg/kg group (P>0.05 for all). The incidence rate of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group, and G-CSF 5 μg/kg group were 69.7%, 68.4%, and 69.5%, respectively, with a non-significant difference among the three groups (P=0.963). The incidence rate of febrile neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg/kg group were 6.1%, 6.4%, and 5.5%, respectively, showing no significant difference among them (P=0.935). The incidence rate of adverse events in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg / kg group were 6.7%, 4.1%, and 5.5%, respectively, showing a non-significant difference among them (P=0.581).

CONCLUSIONSIn patients with breast cancer and non-small cell lung cancer (NSCLC) undergoing TAC/TA chemotherapy, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF at 48 hours after chemotherapy show definite therapeutic effect with a low incidence of adverse events and mild adverse reactions. Compared with the continuous daily injection of rhG-CSF 5 μg/kg/d, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF has similar effect and is more advantageous in preventing chemotherapy-induced neutropenia.

OBJECTIVETo investigate the prognostic impact of different chemotherapy strategies on small cell esophageal carcinoma (SCEC).

METHODSThe clinical data of 62 patients with histologically confirmed SCEC treated in our department between January 2006 and April 2011 were retrospectively analyzed. There were 39 patients with limited stage (LS) and 23 patients with extensive stage (ES) SCEC according to the Veterans Administration Lung Study Group staging system. Cox's hazard regression model was used to determine the prognostic factors, and Chi-square test was used to detect the difference of frequencies among different groups. Kaplan-Meier and log-rank analyses were used to estimate and compare the survival rates.

RESULTSThe chemotherapy combined with local therapy group was significantly better than chemotherapy alone group in median survival time (MST) (20.8 vs. 7.6 months, P<0.05). The MST was 18.0 months and the 1-, 2-, and 3-year overall survival rates (OS) were 68.8%, 38.6%, and 20.9%, respectively, for all the 62 patients. Etoposide plus cisplatin or carboplatin (EP/CP) did not result in significantly longer MST, compared with that of the cases treated by other combination chemotherapy (P>0.05, for either LS or ES cases). Multivariate analysis showed that the VALSG stage, the number of chemotherapy cycles (≥ 4), and treatment modality are independent prognostic factors (P<0.05).

CONCLUSIONSSCEC is a tumor characterized by high malignancy and poor prognosis. Chemotherapy combined with local therapy is an effective treatment for SCEC, and appropriate chemotherapy cycles (≥ 4) may improve the survival time. EP/CP, as commonly used multidrug chemotherapy regimen, is not superior to other combination chemotherapy.

OBJECTIVETo explore the clinical diagnostic features and treatment of desmoplastic small round cell tumor (DSRCT), and to improve the understanding and management of this tumor.

METHODSThe clinicopathological data of nine patients treated in our hospital from October 2004 to June 2014 were retrospectively analyzed and a review of the literature was made. The clinical manifestations, pathological characteristics, diagnosis and differential diagnosis, treatment and prognosis of this tumor were summarized and analyzed.

RESULTSNine patients with DSRCT, 5 males and 4 females, with an average age of 21 years (range 8-56 years) were included in this study. Ultrasound examination revealed irregular low-density mass shadow in the abdominal cavity. CT examination found that 6 cases had abdominal and retroperitoneal multiple solid tumor nodules, uneven density, and visible low density fluid area. Postoperative pathological examination revealed that the tumor cells were small, mostly elliptic, gathered to form clear structure of nests with clear irregular boundaries. The central portion of large tumor nests often showed necrosis. Scattered fibroblasts and large amount of hyalinization of collagen fibers were seen in the interstitial tissue around the nests. Six patients received laparotomy surgery, however, all failed to resect the tumor completely. Three patients received postoperative chemotherapy, i. e. two cases had carboplatin and paclitaxel chemotherapy, and one case of chemotherapy regimen not specified. Two patients had radiation and chemotherapy (no concrete plan was available). Another case was lost to follow-up. Two of the three patients without surgery received chemotherapy with CAP (cyclophosphamide+adriamycin+carboplatin) and total rectal lesions, pelvic and inguinal lymph nodes, ilium metastases radiation therapy. Another one patient received EP regimen (DDP+VP16) which was then changed into a TP chemotherapy alone. Eight of the nine cases died shortly after surgery, and only one patient treated with chemotherapy alone was still alive after 11 months of follow-up.

CONCLUSIONSDesmoplastic small round cell tumor is a very rare, special type of soft tissue tumor, with very poor prognosis. This tumor may be preliminarily diagnosed according to the imaging characteristics and detection of tumor markers, however, final diagnosis is made by pathology. Surgery is the priority of treatment, combined with complementary radiation and chemotherapy.

OBJECTIVE: The concept of platinum sensitivity and cross-resistance among platinum agents are widely known in the management of recurrent ovarian cancer. The aim of this study was to evaluate two hypotheses regarding the validity of the concept of platinum sensitivity and non-cross-resistance of cisplatin analogue with cisplatin in recurrent cervical cancer. METHODS: In this retrospective study, the clinical data of patients with recurrent cervical cancer, who had a history of receiving cisplatin based chemotherapy (including concurrent chemoradiotherapy [CCRT] with cisplatin) and who received second-line chemotherapy at the time of recurrence between April 2004 and July 2012 were reviewed. RESULTS: In total, 49 patients-34 squamous cell carcinomas (69.4%) and 15 non-squamous cell carcinomas (30.6%)-were enrolled. The median age was 53 years (range, 26 to 79 years). Univariate and multivariate analysis showed that a platinum free interval (PFI) of 12 months has a strong relationship with the response rate to second-line chemotherapy. Upon multivariate analysis of survival after second-line platinum-based chemotherapy, a PFI of 12 months significantly influenced both progression-free survival (hazard ratio [HR], 0.349; 95% confidence interval [CI], 0.140 to 0.871; p=0.024) and overall survival (HR, 0.322; 95% CI, 0.123 to 0.842; p=0.021). In patients with a PFI of less than 6 months, the difference of progression-free survival between patients with re-administration of cisplatin (3.0 months) and administration of cisplatin analogue (7.2 months) as second-line chemotherapy was statistically significant (p=0.049, log-rank test). CONCLUSION: The concept of platinum sensitivity could be applied to recurrent cervical cancer and there is a possibility of noncross-resistance of cisplatin analogue with cisplatin.

OBJECTIVE: There is no research regarding the appropriate antiemetic agents for female patients, especially those receiving moderately emetogenic chemotherapy (MEC). We evaluated the antiemetic efficacy of a combination of 5-HT3 receptor with/without aprepitant in patients with gynecological cancer treated with the TC (paclitaxel and carboplatin) regimen of MEC. METHODS: We enrolled 38 patients diagnosed with gynecologic cancer and scheduled to receive the TC regimen. The patients were randomly assigned to receive a 5-HT3 receptor antagonist, either palonosetron in the first cycle followed by granisetron in the second cycle or vice versa. In the third cycle, all patients received a combination of the 5-HT3 receptor and dexamethasone with/without aprepitant. RESULTS: When three drugs were administered, palonosetron consistently produced an equivalent complete response (CR) rate to granisetron in the acute phase (89.5% vs. 86.8%, p=0.87) and delayed phase (60.5% vs. 65.8%, p=0.79). With regard to the change in dietary intake, palonosetron exhibited similar efficacy to granisetron in the acute phase (92.1% vs. 89.4%, p=0.19) and delayed phase (65.7% vs. 68.4%, p=0.14). However, in the delayed phase, the addition of aprepitant therapy with a 5-HT3 receptor antagonist and dexamethasone produced a higher CR rate than a 5-HT3 receptor antagonist with dexamethasone (93.3% vs. 47.8%, p<0.001) and allowed the patients to maintain a higher level of dietary intake (93.3% vs. 56.5%, p<0.001). CONCLUSION: The addition of aprepitant therapy was more effective than the control therapy of a 5-HT3 receptor antagonist, and dexamethasone in gynecological cancer patients treated with the TC regimen.

OBJECTIVETo compare the efficacy and safety between liposome-paclitaxel plus carboplatin (LPC) and paclitaxel plus carboplatin (PC) as first-line treatment for advanced non-small cell lung cancer (NSCLC).

METHODSTotally 54 chemotherapy-naive NSCLC patients were equally and randomly assigned into LPC group and PC group. Liposome-paclitaxel was injected on D1 at a dosage of 175 mg/m(2); the same dose and administration with paclitaxel injection in the PC group for a maximum of 2 cycles. The efficacy and adverse reactions after 2 cycles of chemotherapy were compared between these two groups.

RESULTSThe overall response rate (CR+PR) was 44.4% in the LPC group and 33.3% in the PC group after 2 cycles of chemotherapy respectively (P=0.577). In the LPC group and PC group, the incidences of myelodepression was 81.5% and 63.0%, respectively (P=0.080), gastrointestinal toxicity was 96.3% and 77.8% respectively (P=0.100), and allergic reactions was 0 and 11.1%, respectively (P=0.000). The median time to progression was 6 months and 5 months, respectively (P=0.420).

CONCLUSIONLPC group has the same efficacy with PC group and less adverse reactions than PC group.

OBJECTIVEThe aim of this study was to analyze the clinical characteristics, treatment and prognosis of advanced urothelial carcinoma of the bladder (AUCB).

METHODSThe clinicopathological data of 117 patients with AUCB admitted in our hospital from 1998 to 2009 were reviewed. All patients received first-line chemotherapy. The survival rate was calculated by Kaplan-Meier analysis and log-rank test.

RESULTSThe median age of all patients was 56 years and the male-to-female ratio was 3.33:1. Their 6-, 12-, 24-, 36- and 60-month survival rates were 90.3%, 61.3%, 32.3%, 24.2% and 8.1%, respectively. In the first-line chemotherapy regimen, the effectiveness rate of gemcitabine + platinum drugs was 49.3% (37/75), the median progression-free survival(PFS) was 7.9 months and overall survival (OS) was 18.7 months. The effectiveness of cyclophosphamide + epirubicin + platinum drug regimen was 45.5% (10/22), Median PFS was 7.1 months and OS was 15.3 months. The effectiveness of paclitaxel + platinum drug regimen was 47.1% (8/17), median PFS was 6.5 months and OS was 13.7 months. Among them, the effectiveness rate of the gemcitabine + cisplatin regimen in 67 patients was 47.8%, the median PFS was 7.0 months and OS was 15.3 months. In the 13 patients who received paclitaxel + carboplatin regimen, the effectiveness rate was 53.8%, median PFS was 7.7 months and OS was 16.0 months. The major side effects were leucopenia and thrombocytopenia, mostly were tolerable, of grade I to II.

CONCLUSIONSIn advanced unresectable and metastatic urothelial carcinoma of the bladder, GC regimen is recognized as a standard first-line chemotherapy, with a higher effectiveness and tolerable side effects. Taxane and molecular targeted drugs may further improve the therapeutic effect of the treatment of advanced urothelial carcinomas of the bladder in the future.

PURPOSE: To investigate chemosensitivity with an adenosine triphosphate-based chemotherapy response assay in patients with epithelial ovarian or peritoneal cancer according to tumor histology, grade, and disease status. MATERIALS AND METHODS: One hundred specimens were collected during primary or secondary debulking from 67 patients with primary ovarian cancer, 24 patients with recurrent ovarian cancer, 5 patients with primary peritoneal cancer, and 4 patients with recurrent peritoneal cancer; samples were collected between August 2006 and June 2009. Tumor cells were isolated and cultured for 48 hours in media containing chemotherapy. The chemosensitivity index (CI) was calculated as 300 minus the sum of the cell death rate at 0.2x, 1x, and 5x drug concentrations, and the CI values were compared. RESULTS: CI values were obtained from 93 of 100 patients. The most active agents against primary disease were ifosfamide and paclitaxel. For primary serous adenocarcinoma, paclitaxel and irinotecan were the most active, followed by ifosfamide. For clear cell carcinoma, ifosfamide was the most active, followed by paclitaxel and irinotecan. Although not statistically significant, the CIs of cisplatin, carboplatin, paclitaxel, and docetaxel decreased as tumor grade increased. In 14 cases of recurrent disease, paclitaxel was the most active, followed by ifosfamide and cisplatin. CONCLUSION: Ifosfamide and paclitaxel were the most active drugs for primary and recurrent disease. Therefore, we recommend further clinical studies to confirm the efficacy of paclitaxel, ifosfamide, and cisplatin combination chemotherapy for recurrent and primary ovarian cancer.
