Oxaliplatin plus fluorouracil/folinic acid (5-FU/FA) every 2 weeks has shown promising activity in advanced gastric cancer. This study assessed the efficacy and safety of weekly oxaliplatin plus 5-FU/FA (FUFOX regimen) in the metastatic setting. Patients with previously untreated metastatic gastric cancer received oxaliplatin (50 mg m(-2)) plus FA (500 mg m(-2), 2-h infusion) followed by 5-FU (2000 mg m(-2), 24-h infusion) given on days 1, 8, 15 and 22 of a 5-week cycle. The primary end point of this multicentre phase II study was the response rate according to RECIST criteria. A total of 48 patients were enrolled. Median age was 62 years and all patients had metastatic disease, with a median number of three involved organs. The most common treatment-related grade 3/4 adverse events were diarrhoea (17%), deep vein thrombosis (15%), neutropenia (8%), nausea (6%), febrile neutropenia (4%), fatigue (4%), anaemia (4%), tumour bleeding (4%), emesis (2%), cardiac ischaemia (2%) and pneumonia (2%). Grade 1/2 sensory neuropathy occurred in 67% of patients but there were no episodes of grade 3 neuropathy. Intent-to-treat analysis showed a response rate of 54% (95% CI, 39-69%), including two complete responses. At a median follow-up of 18.1 months (range 11.2-26.2 months), median survival is 11.4 months (95% CI, 8.0-14.9 months) and the median time to progression is 6.5 months (95% CI, 3.9-9.2 months). The weekly FUFOX regimen is well tolerated and shows notable activity as first-line treatment in metastatic gastric cancer.

A multicentre phase II trial to determine the efficacy of vinflunine as second-line therapy in patients with advanced transitional cell carcinoma (TCC) of the bladder; secondary objectives were to assess duration of response, progression-free survival (PFS) and overall survival (OS), and to evaluate the toxicity associated with this treatment. Patients had tumours that failed or progressed after first-line platinum-containing regimens for advanced or metastatic disease, or had progressive disease after platinum-containing chemotherapy given with adjuvant or neoadjuvant intent. Response and adverse events were assessed according to WHO criteria and NCI-CTC (version 2), respectively. Out of 51 patients treated with 320 mg m(-2) of vinflunine, nine patients responded to the therapy yielding an overall response rate of 18% (95% CI: 8.4-30.9%), and 67% (95%CI: 52.1-79.3%) achieved disease control (PR+SD). Of note, responses were seen in patients with relatively poor prognostic factors such as a short (<12 months) interval from prior platinum therapy (19%, including an 11% response rate in those progressing <3 months after platinum treatment), prior treatment for metastatic disease (24%), prior treatment with vinca alkaloids (14%) and visceral involvement (20%). The median duration of response was 9.1 months (95% CI: 4.2-15.0) and the median PFS was 3.0 months (95% CI: 2.4-3.8). The median OS was 6.6 months (95% CI: 4.8-7.6). The main haematological toxicity was grade 3-4 neutropenia, observed in 67% of patients (42% of cycles). Febrile neutropenia was observed in five patients (10%) and among them two were fatal. Constipation was frequently observed (but was manageable and noncumulative) and was grade 3-4 in only 8% of patients. The incidence of grade 3 nausea and vomiting was very low (4 and 6% of patients, respectively). Neither grade 3-4 sensory neuropathy nor severe venous irritation was observed. Moreover, and of importance in this particular study population, no grade 3-4 renal function impairment was observed. Vinflunine is an active agent for the treatment of platinum-pretreated bladder cancer, and these results warrant further investigation in phase III trials, either as monotherapy or in combination with other agents as treatment of advanced/metastatic TCC of the bladder.

The effectiveness and toxicity of antitumor drugs vary depending on dosing time associated with the 24-h rhythms of biochemical, physiological, and behavioral processes under the control of the circadian clock. Such chronopharmacological phenomena are influenced by not only the pharmacokinetics but also pharmacodynamics of medications. For example, the antitumor effect and/or toxicity of irinotecan hydrochloride, interferon, and antiangiogenic agents vary depending on the dosing time associated with the 24-h rhythm of their target enzyme, receptor, protein, and pharmacokinetics. Many of them are controlled by clock genes. Chronotherapy is especially relevant when the risk and/or intensity of the symptoms of disease vary predictably over time. In a randomized multicenter trial involving patients with previously untreated metastases from colorectal cancer, the chronomodulated infusion of oxaliplatin, fluorouracil (5-FU), and folinic acid is compared with a constant-rate infusion method. Side effects such as stomatitis, peripheral sensory neuropathy are lower and the objective response is higher in the chronotherapy as compared with the fixed-rate infusion. The merit of chronomodulated infusion is supported by the 24-h rhythm of DNA synthesis and the activity of dehydropyrimidine dehydrogenase, which brings about the intracellular catabolism of 5-FU. Although interferon (IFN) also alters the clock function, the disruptive effect of IFN on clock function can be overcome by devising a dosing regimen that minimizes adverse drug effects on clock function. Thus one approach to increasing the efficiency of pharmacotherapy is the administration of drugs at times at which they are most effective and/or best tolerated.

Paraneoplastic syndromes (PNS) represent the clinical manifestation of the remote and indirect effects produced by tumor metabolites or other products. Paraneoplastic effects are not directly mediated by tumor invasion of normal tissue, or by the disruption of normal function of the involved organ, or by distant metastases. More than 260 cases of nasopharyngeal carcinoma (NPC) associated with PNS have been reported in the literature. These syndromes can be divided into six main groups: cutaneous or dermatologic, endocrine, hematologic, osteoarticular or rheumatologic, neurologic, and ocular. The most common dermatologic manifestation is dermatomyositis, while the syndrome of inappropriate secretion of antidiuretic hormone and occasionally Cushing's syndrome due to ectopic ACTH production are the endocrinologic manifestations. Tumor fever and leukemoid reaction, osteoarticular or rheumatic syndromes, including clubbing of the fingers and toes, sensory neuropathy and demyelinating motor polyneuropathy, and rarely optic neuritis represent the most prominent examples of the other groups of syndromes. PNS may occur before the NPC is manifest, or while it is in an occult stage, and thus the possibility of NPC should be considered in patients with these various disorders. While some PNS will respond to direct treatment, most often the PNS subsides in parallel to response of the NPC, and thus may be useful for monitoring tumor response or recurrence.

Numb chin syndrome (NCS) is a sensory neuropathy presenting with numbness of the chin in the distribution of the mental nerve and the branches of the mandibular division of the trigeminal nerve. Though it can be caused by a benign process, NCS should be regarded as being due to malignancy until proven otherwise. Among the malignancies that cause NCS the most common are breast cancer, prostate cancer, and lymphoreticular malignancy. In squamous cell carcinoma (SCC) of the esophagus, spread to the mandible is a rare and often late event. An often overlooked clinical sign in mandibular metastases is hypoesthesia or paresthesia over the peripheral distribution of the inferior alveolar nerve/mental nerve; this sign has been referred to in the literature as NCS or numb lip syndrome or mental nerve neuropathy. Rarely, this may be the first presentation of a disseminated malignancy. Prognosis is usually poor. The discovery of this symptom should alert the clinician to the possibility of disseminated disease. In this article we report a rare case of metastatic SCC of the esophagus in a 40-year-old male patient who presented with NCS. We also review the mechanism, causes, and evaluation of NCS.

The combination of oxaliplatin plus fluorouracil/leucovorin is known as the FOLFOX regimen, and it has become a standard regimen for colorectal cancer (CRC), both as adjuvant therapy and as treatment for metastatic disease. Unfortunately, platinum-based chemotherapies also produce neurotoxicity as a side effect. Neurotoxicity is the most common dose-limiting toxicity of oxaliplatin, and it is one of the major causes for patients to stop receiving chemotherapy. It can manifest as either of two distinct syndromes: a transient, acute syndrome that can appear during or shortly after the infusion (approximately 1%-2% of patients), and a dose-limiting, cumulative sensory neuropathy. Calcium/magnesium (Ca/Mg) infusions have been used to decrease the incidence of oxaliplatin-induced neuropathy. The actual utility of Ca/Mg infusions in this setting has been an interesting and controversial topic. They may reduce the severity of neurotoxicity, but some investigators have questioned whether they also will alter the efficacy of these chemotherapy regimens. In this paper, we review the clinical data concerning the usefulness of Ca/Mg infusions in reducing the incidence of oxaliplatin-induced neuropathy as well as their effect on responsiveness to chemotherapy.

Mental nerve neuropathy (numb chin/lip syndrome) is a sensory neuropathy presenting with numbness in the distribution of the inferior alveolar nerve/mental nerve (chin and lower lip). This is typically unilateral and can be secondary to dental disease or malignancy. When caused by malignancy, these symptoms can be either an initial presentation of an unsuspected tumor or progressive metastatic disease, both of which would indicate poor prognosis. We describe a 48-year-old female patient with a history of breast cancer who presented with left chin numbness and manifested a metastatic lesion involving the left mandibular foramen on PET/CT and subsequent MRI.

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.

This study was aimed to assess the feasibility and short-term outcomes of adjuvant systemic chemotherapy with either S-1/oxaliplatin (SOX) or mFOLFOX6 (FOLFOX)after curative resection of distant metastases from colorectal cancer. We retrospectively examined 16 patients who underwent R0 resection of colorectal metastases, including the liver (n=6), lung (n=5), lymph node (n=3), and peritoneum (n=2), followed by chemotherapy with SOX (n=7) or FOLFOX (n=9) until disease progression. The mean recurrence-free survival was 13.2 months in the SOX group and 16.9 months in the FOLFOX group. The mean overall survival was 17.9 and 22.9 months, respectively. The number of given courses were 6.5 and 11.0, respectively. Although sensory neuropathy was observed in 38% of the patients, relative dose intensity was higher than 80%. Adjuvant chemotherapy with SOX or FOLFOX was feasible and effective. Further randomized prospective trials are warranted to confirm these results.

Nanoparticle albumin-bound paclitaxel(nab-PTX)is effective as second-line chemotherapy for advanced gastric cancer. Long-term administration is generally impossible because of peripheral sensory neuropathy. However, we report 2 cases that were treated with>35 cycles of nab-PTX with dose reduction to control disease progression, which appears to be the highest number cycles so far reported. Case 1 was a male patient in his 70s, with distant lymph node metastases and an advanced primary lesion(tub2). He received 6 cycles S-1/CDDP and achieved a partial response; however, the treatment was changed to second-line chemotherapy with nab-PTX because of adverse effects; the dose of nab-PTX was reduced by 60% every 3 weeks. At the time of writing, 36 cycles have been administered and disease control has been maintained, with Grade 2 peripheral sensory neuropathy. Case 2 was another male patient in his 70s, who underwent total gastrectomy for gastric cancer(mucinous adenocarcinoma). Virchow metastasis was detected 6months after surgery. He received 1 cycle S-1/CDDP and achieved a partial response; however, treatment was changed to second-line chemotherapy with nab-PTX because of adverse effects; the dose of nab-PTX was reduced by 60% every 3 weeks. At the time of writing, 41 cycles have been administered and disease control has been maintained, with Grade 2 peripheral sensory neuropathy.
