A total of 55 patients with measurable colorectal metastatic carcinoma were studied to evaluate the impact on toxicity, response, and survival of protracted venous infusion (PVI) 5-FU 200 mg/m2 per day with Cis-
DDP
80 mg/m2 or carboplatin 300 mg/m2 every 3 weeks, 1-hour infusion. Patients received continuous uninterrupted therapy until there were signs or symptoms of toxicity. Both 5-FU and cisplatin were withheld when patients experienced grade II stomatitis and diarrhea, severe nausea or vomiting not controlled by standard antiemetic therapy, and clinically significant hand-foot syndrome. The toxicity was neurological (20% grade 2 and 3) hematological (13% grade 2) and dermatological (11% grade 2). The overall response (CR+PR) was 24% with a median survival of 13 months. The results of our study show that there is no improvement in response rate, response duration or survival compared with historical trials. However, this study does confirm the valuable palliative role of the protracted 5-FU infusion treatment. Colorectal carcinoma is one of the most common neoplasms in Western societies, being second only to lung cancer as a cause of death from malignancy. The management of nonmetastatic primary disease in surgical, with adjuvant chemotherapy for those at high risk of relapse. However, for those with
metastatic disease
at diagnosis or recurrent disease after resection, cytotoxic chemotherapy is the treatment of choice and fluorouracil (5-FU) is the most active cytotoxic agent in this disease, with a response rate of approximately 20%. Efforts to improve the response rate have focused on the use of agents to modulate 5 FU. The Southwestern Oncology Group (SWOG) study reported by Leichman et al. (1) and a study from the United Kingdom by Hill et al. (2) compared conventional FU to modulated FU and found no improvement in response rate or survival. In the SWOG study, two different schedules of bolus FU and LV were compared with bolus FU alone and to continuous infusion FU administered alone or modulated by LV or PALA. In this study, the results obtained with bolus FU were superior to most of the studies in the literature: The response rate was 26%, and the median survival was 14 months. The high- and low-dose LV and FU groups showed response rates and survival similar to bolus FU alone. However, in 12 previously reported randomized studies comparing FU and LV or FU alone, nine reported that the combination of FU and LV produced significant increases in response rates and two reported significant increase in survival (3, 4). Many of these trials used the dose schedules reported in the SWOG trial. Protracted venous infusion (PVI) 5-FU has been shown to have superior efficacy with less toxicity in colorectal cancer when compared to bolus 5-FU and synergy between cisplatin and 5-FU has been demonstrated in vitro. Consequently, we have investigated the efficacy of the combination of bolus cis or carboplatin and PVI 5 FU in 55 patients with advanced colorectal cancer using survival, response rate, symptomatic response, and toxicity as study endpoints.

The combination of dacarbazine (DTIC), cisplatin (
DDP
), carmustine and tamoxifen (TAM) has been reported to yield a high rate of response in patients with metastatic melanoma, but responders often experience intracranial recurrences. As fotemustine (FOT) has demonstrated activity on cerebral
metastases
, the rationale of this study was to replace carmustine by FOT in this four-drug regimen. Twenty patients with metastatic melanoma received FOT (100 mg/m2) on days 1 and 8, DTIC (220 mg/m2 per day) and
DDP
(25 mg/m2 per day) from day 1 to day 3 and from day 28 to day 30, and continuous daily treatment with TAM (20 mg/day). If stabilization or response was observed at the end of the 8th week, patients received maintenance courses of FOT on day 1, and DTIC (220 mg/m2 per day) and
DDP
(25 mg/m2 per day) on days 1 to 3. Nineteen patients were evaluable. Of these, six had brain metastases. The overall response rate was 10.5% (two out of 19); both of the responders had only partial responses. The best responding site was lung. No response was obtained in the four patients with evaluable brain metastases, but no patient had therapy failure due to new brain metastases. The median overall survival was 5 months (range 1-45 months). Toxicity was mainly haematological. The use of this combination is not recommended.

Lymph node metastasis is often the first indication of the aggressiveness of breast cancer. Effective chemotherapy in breast cancer depends on targeting the metastatic component of the disease. In order to optimize chemotherapy in the metastatic target of breast cancer, the histoculture drug response assay (HDRA) was performed on surgical specimens of primary tumor and axillary lymph node metastasis from 30 breast cancer patients. The surgical specimens were cut into approximately 10 mg pieces, and placed onto the collagen gel sponges in the medium containing previously-determined cutoff concentrations of doxorubicin (DXR), 5-fluorouracil (5-FU), cisplatin (
DDP
), and mitomycin C (MMC). After incubation for 7 days, the chemosensitivity of the tumor fragments was evaluated with the 3-(4,5-dimethythiazol2yl)-2,5-diphenyl-2H tetrazolium bromide (MTT) endpoint. The lymph node
metastases
were more resistant than the primary tumor for DXR, 5-FU, and MMC (p < 0.05) but not for CDDP. The data suggest that both primary tumor and
metastases
from individual patients should be tested in the HDRA to enhance clinical efficacy of chemotherapy.

Purpose. To report the outcome of 37 patients with metastatic osteosarcoma entered into a large randomized trial (EOI 80831/MRC B002) comparing two different regimens of chemotherapy in patients with osteosarcoma.Methods. Patients with biopsy-proven osteosarcoma localized and metastatic, age 40 years or younger, were randomized to receive either two-drug treatment with doxorubicin/cisplatin (DOX 25 mg m(-2) day(-1) x 3 +
DDP
100 mg m(-2) on day 1 q 3 weeks x 6 courses) or three-drug treatment comprising high-dose methotrexate (HDMTX 8 mg m(-2) administered every 4.5 weeks x 4 courses) given 10 days before DOX/
DDP
.Results. Twenty-four patients with
metastatic disease
received the two-drug arm treatment and 13 received three-drug treatment. Despite chance imbalance in numbers, there were no major differences in age, sex, primary site or performance status. Baseline alkaline phosphatase (AP) was elevated more frequently (96 vs 42%) in the two-drug arm. Twenty-one of 24 patients in the two-drug arm and 11/13 patients in the three-drug arm had evaluable primary tumors concurrent with
metastases
. Respective clinical response rates for the two- and three-drug arms were 48% and 40% for primary tumors, and 33% and 55% for
metastases
. Respective survivals at 2 and 4 years were 36% and 9% for the two-drug arm, and 69% and 52% for the three-drug arm, and survival was better for patients with normal AP at presentation. When adjusted for AP, survival was not significantly different between the two treatments (hazard ratio 0.52, 95% confidence interval 0.22-1.23, p = 0.14). There were three long-term survivors among the metastatic patients, all of whom received the three-drug therapy.Discussion. It is likely that random bias in the population (small numbers, imbalance in size of groups, uneven distribution of AP) accounts for the difference in outcome favoring the three-drug treatment in patients with
metastatic disease
. More reliance can be placed on the finding that disease-free and overall survival in the adjuvant component of this study (Bramwell et al., J Clin Oncol 1992; 10: 1579-91) were better after two-drug treatment.

Esophageal cancer is a major health hazard in many parts of the world and is often diagnosed late. The objective of this study was to explore the efficacy and safety of nanoparticle albumin-bound paclitaxel (Nab-PTX) combined with cisplatin (
DDP
) in patients with metastatic esophageal squamous cell carcinoma (ESCC). Patients with histologically confirmed ESCC were treated with Nab-PTX 250 mg/m(2) and
DDP
75 mg/m(2) intravenously on day 1, every 21 days. Evaluation was performed after every two cycles of therapy and the therapy was continued until disease progression or unacceptable toxicity. From April 2010 to December 2012, 33 patients were enrolled. Ten patients had recurrent and metastatic tumors after surgery and 23 patients were diagnosed with unresectable
metastatic disease
. Patients received a median of four cycles of therapy (ranging from two to six cycles). Twenty patients achieved partial response and nine patients achieved stable disease; no complete response was observed. The objective response rate was 60.6% and the disease control rate was 87.9%. The median progression-free survival was 6.2 months (95% confidence interval: 4.0 to 8.4 months) and the median overall survival was 15.5 months (95% CI: 7.6 to 23.4 months). Only four patients experienced grade 3 adverse events, including vomiting, neutropenia, and sensory neuropathy. The most common adverse events were nausea/vomiting (81.8%), neutropenia (63.6%), leucopenia (48.5%), anemia (24.2%) and sensory neuropathy (24.2%). In conclusion, the combination of Nab-PTX and
DDP
is a highly effective and well-tolerated first-line treatment in metastatic ESCC.

The goal of this study was to assess the efficacy of concurrent chemotherapy to intensity-modulated radiotherapy (IMRT) after neoadjuvant chemotherapy (NACT) in locoregionally advanced nasopharyngeal carcinoma (NPC). A total of 120 patients with stage III-IVB NPC treated with NACT followed by IMRT alone (39 patients, arm 1) or CCRT (81 patients, arm 2) between May 2009 and June 2012 were eligible for study inclusion. NACT consisted of docetaxe (DOC, 60 mg/m(2), day 1) and cisplatin (
DDP
, 100 mg/m(2), days 1-5, every 3 weeks). Concurrent chemotherapy was nedaplatin (NDP, 25 mg/m(2), days 1-3, every 3 weeks). The median follow-up period was 41 (range 5-52) months, and the 3-year overall survival, distant
metastases
-free survival, locoregional relapse-free survival, and progression-free survival rates of arm 1 and arm 2 were 83.3 and 87.4% (P = 0.516), 81.7 and 79.6% (P = 0.596), 86 and 92.3% (P = 0.920), 76.4 and 76.4% (P = 0.709), respectively. During radiotherapy, the most commonly recorded grade 3/4 adverse events were anemia (7.7 vs. 4.9%), leucopenia (10.2 vs. 3.7%), thrombocytopenia (12.8 vs. 3.7%), neutropenia (15.4 vs. 6.2%), nausea/vomiting (7.7 vs. 12.3%), stomatitis/mucositis (38.5 vs. 46.9%), xerostomia (35.9 vs. 30.8%), dermatitis (7.7 vs. 7.4%), and fatigue(15.4 vs. 17.2%) for arm 1 and arm 2. The results of this study indicated that added concurrent chemotherapy to IMRT after neoadjuvant DOC and
DDP
treatment for locoregionally advanced NPC was probably not be necessary.

Cervical cancer is the third most commonly diagnosed cancer worldwide and the fourth leading cause of cancer-related mortality in females worldwide, accounting for 10-15% of cancer-related mortalities. Cytological screening and DNA testing for high-risk human papillomavirus (HPV) types have markedly decreased the rates of cervical cancer in developed countries, however, for vulnerable populations without access to health care, cervical cancer remains a considerable problem. Chemotherapeutic agents such as cisplatin (
DDP
) are considered as first-line treatment for cervical carcinoma. Although initially patients often exhibit high responsiveness, the majority eventually develop
DDP
resistance. However, the mechanisms underlying this process remain unclear. Furthermore, patients with
metastatic cancer
and those exhibiting persistent or recurrent disease after platinum-based chemoradiotherapy have limited options and thus, non-platinum combination chemotherapy has been proposed as a strategy to circumvent platinum resistance, however, novel therapeutic strategies are required. In the present study, P16 expression was analyzed by quantitative-polymerase chain reaction and western blot analysis in SiHa and SiHa-
DDP
cells and the interaction between P16 and CDK4 was detected via co-immunoprecipitation. In addition, the proliferation and apoptosis rates of P16 knockdown SiHa-
DDP
cells were measured by MTT assay and Annexin V flow cytometry and the subsequent changes in cyclin D1 and pRb expression were analyzed by western blot analysis. In this study, a high level of P16
INK4A
expression and its enhanced interaction with cyclin-dependent kinase-4 in cervical carcinoma
DDP
-resistance cells (SiHa-DDP) was identified, which was associated with the inactivation of phosphorylated retinoblastoma protein (pRb). Knockdown of P16
INK4A
significantly induced cellular growth, when compared with the control cells, via the upregulation of pRb, and also promoted apoptosis following treatment with
DDP
. The results of this study indicated, for the first time, that P16
INK4A
is required for
DDP
resistance in cervical carcinoma SiHa cells and, thus, these results may lead to the development of novel strategies for the treatment of chemoresistant cervical carcinoma.

Contactin-1 (CNTN-1), a glycosyl phosphatidylinositol anchor neural cell adhesion molecule (ACAM), is thought to function not only in nervous system development but also in the invasion and metastasis of several tumours. To investigate whether CNTN-1 is involved in multidrug resistance (MDR) in lung adenocarcinoma, CNTN-1 expression was compared between MDR human lung adenocarcinoma A549/cisplatin (A549/
DDP
) cells and its progenitor A549 cells. The comparison showed that CNTN-1 expression in A549/
DDP
cells was significantly higher than in A549 cells both at the mRNA level and the protein level. In order to confirm the physiological function of the abnormal expression, lentivirus-mediated short hairpin RNA (shRNA) was used to silence CNTN-1. Cell cytotoxicity assay and cell apoptosis assay revealed that silencing CNTN-1 both in A549 cells and in A549/
DDP
cells not only rendered cells more sensitive to cisplatin than the negative control, but also increased the cisplatin-induced apoptosis.
Metastasis
and invasion assays demonstrated that CNTN-1 knockdown reduced metastasis and invasion but did not affect A549 or A549/
DDP
cell proliferation. To investigate whether the abnormal expression of CNTN-1 is associated with characteristics of patients with non-small cell lung cancer (NSCLC), immunohistochemistry was used to detect CNTN-1 expression in 143 tissue samples from NSCLC patients and the results showed that the degree of CNTN-1 expression positively correlated with lymphatic invasion in patients with lung adenocarcinoma who received adjuvant cisplatin- or carboplatin-based treatment after surgery. Thus, we concluded that CNTN-1 is closely related with MDR of lung adenocarcinoma. Additionally, CNTN-1 is a novel marker to predict chemotherapeutic efficacy of patients with lung adenocarcinoma, especially with regard to cisplatin- or carboplatin-based regimens.

Cediranib is a pan-vascular endothelial growth factor receptor tyrosine kinase inhibitor that affects tumor angiogenesis and is under investigation in clinical studies on ovarian cancer. Using a panel of eleven patient-derived ovarian cancer xenografts (EOC-PDX) growing orthotopically in the peritoneal cavity of nude mice we investigated the effect of cediranib as monotherapy or in combination with chemotherapy on overall survival (primary endpoint, at euthanasia), and tumor dissemination and metastasis in the peritoneal cavity (secondary endpoint, interim analysis). The response of EOC-PDX to cediranib varied (increment of lifespan, ILS between 12 and 85 %) in the different EOC-PDX, independently from tumor responsiveness to cisplatin (
DDP
). Cediranib combined with
DDP
and in maintenance regimen prolonged the survival of mice bearing EOC-PDX with different responsiveness to
DDP
(ILS between 34 and 224 % with only
DDP
and between 135 and 337 % with
DDP
plus Cediranib); survival was extended with the addition of paclitaxel to chemotherapy (50-77 % complete remissions). Cediranib reduced ascites of advanced EOC-PDX, but had limited effect on tumor dissemination; only combined with chemotherapy, ascites and
metastases
were both reduced. The reduction of tumor dissemination was associated to the increase of overall survival. In conclusion, the response to cediranib differs in the various EOC-PDX, reproducing the heterogeneous response of cancer patients to angiogenesis inhibitors. Cediranib potentiated chemotherapy, significantly inhibiting tumor progression and dissemination to metastatic organs, even in tumors poorly responsive to
DDP
. EOC-PDX preclinical models with different responsiveness to Cediranib may help in identifying determinants of response to cediranib and mechanisms of adaptation to antiangiogenic treatments.

Cisplatin (diamminedichloroplatinum,
DDP
) is widely used as the first-line treatment for patients with unresectable or no
metastatic cancer
. However, the appearance of
DDP
resistance frequently occurred in the treatment of cancers, including esophageal carcinoma (EC). The purposes of this study are to determine the antitumor effects of miR-let-7g/i (let-7g/i) on EC cells and to investigate whether let-7g and let-7i have a relationship with the drug resistance gene ABCC10 on EC cells. qRT-PCR and western blot analysis demonstrated that Bcl2-associated athanogene 3 (BAG3) and miR-let-7g/i have the opposite expression levels in primary esophageal squamous cell carcinoma tissues and EC cell lines. Overexpression of miR-let-7g/i significantly inhibited the cell proliferation and promoted
DDP
-induced apoptosis of EC109 and TE10 cells. Finally, ABCC10, a drug resistance gene, was identified as a functional and direct target gene of miR-let-7g/i. Luciferase reporter assay confirmed that let-7g and let-7i combined directly with 3'UTR of ABCC10, in consequence, inhibiting ABCC10 expression and enhancing cellular sensitivity to drugs. This study provides the first demonstration that miR-let-7g/i target ABCC10 and modulate
DDP
resistance in EC cell lines.
