Abstract
INTRODUCTION Oligometastatic disease (OMD) is a metastatic stage that could benefit maximally from local therapies. Patients in this state have a better prognosis relative to those with disseminated metastases. Stereotactic radiotherapy provides a non-invasive ablative tool for primary malignant tumors and metastases. MATERIALS AND METHODS We searched our register for patients with oligometastatic or recurrent head and neck cancer (OMD/R-HNC) who received stereotactic radiotherapy to manage their OMD/R. We evaluated the survival outcomes and prognostic factors that affected the survival of those patients. RESULTS In all, 31 patients with 48 lesions met the inclusion criteria for the analysis. The lesions comprised various metastatic sites, with the majority being pulmonary (37 lesions). Squamous cell cancer was the most common histology (26 patients). The median overall survival (mOS) was 33 months, with a progression-free survival (PFS) of 9.6 months. Eight patients received subsequent stereotactic radiotherapy after disease progression. The local control (LC) rates were 91.3, 87.7, and 83% at 6, 12, and 36 months. Patients with the de novo OMD who received stereotactic radiotherapy as their initial treatment had a median systemic treatment-free survival of 23.9 months. In univariate analysis, a trend for better OS was observed in patients with p16-positive squamous cell tumors; patients who progressed within 150 days after diagnosis had a significantly lower OS. De novo OMD showed significantly better PFS compared to induced OMD. Multivariate analyses identified p16-positive squamous cell cancer, metachronous OMD and a longer time to progression as positive predictors of OS, while de novo OMD was the only positive predictor for PFS. Treatment-related toxicities were generally mild, with two cases of grade 3 dysphagia reported. CONCLUSION Stereotactic radiotherapy demonstrated favorable outcomes in patients with OMD/R-HNC with limited toxicities. Further studies are warranted to validate these findings and optimize treatment strategies for this patient population.

Abstract
Aims and background Several strategies combining radiotherapy and chemotherapy have been developed for the cure of squamous cell carcinoma of the head and neck (SCC-HN) in an attempt to improve loco-regional control and survival. This overview aims to summarize clinical results of reported randomized trials and to discuss the biological mechanisms underlying the interactive and non-interactive processes promoted when chemotherapy is added to radiotherapy. Methods The clinical goals of combined modality therapy and exploitable associations of chemotherapy and radiotherapy that may lead to a therapeutic gain in comparison with radiotherapy alone are reported and reviewed. Clinical applications of the four main ways of combining chemotherapy with radiotherapy (neoadjuvant, concomitant, alternating and adjuvant) are briefly re-analyzed and discussed. Results and Conclusions Published evidence suggests that induction chemotherapy (neo-adjuvant) should not be routinely recommended; however, induction chemotherapy increases the likelihood of larynx preservation in patients with laryngeal and hypopharyngeal cancer and should be offered as a treatment option as an alternative to surgery. Positive results of several randomized studies and a recent meta-analysis show that concomitant use of chemotherapy and radiotherapy in unresectable SCCHN is beneficial and should be considered as a potential standard treatment. A complementary biological staging of SCCHN, by evaluating new predictive factors of tumor response, is presently under investigation to better interpretate clinical randomized trials exploring chemo-radiotherapy.

Abstract
PURPOSE The aim of this study was to evaluate the efficacy and toxicity of concurrent chemoradiotherapy using cisplatin (CDDP), 5-fluorouracil (5-FU), methotrexate (MTX) and leucovorin (LV) (PFML) in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN). METHODS Seventy-seven patients with previously untreated stages III-IV SCCHN were included in this trial. Patients received two cycles of chemotherapy repeated every 4 weeks. The chemotherapy regimen consisted CDDP (60 mg/m2, day 4), 5-FU (600 mg/m2 given over 24 h for 5 days, days 1-5), MTX (30 mg/m2, day 1) and LV (20 mg/m2, days 1-5). Radiation was targeted to begin on the starting day of chemotherapy, day 1. The total radiation dose to the primary site and neck lymph nodes was 70.0 Gy. When grade>or=3 toxicities were observed frequently, radiotherapy and/or chemotherapy were delayed or reduced. RESULTS The main toxicities were mucositis (grade>or=3, 39%), leukocytopenia (grade>or=3, 34%) and neutropenia (grade>or=3, 30%). The overall clinical response rate and the pathological complete response (CR) were 94% (72/77) and 71% (55/77). The primary site CR and neck lymph node CR were 79% (61/77) and 85% (44/52), and 3-year survival rate was 73%. CONCLUSIONS This concurrent chemoradiotherapy with PFML was safe and well tolerated. The high CR rate justifies further evaluation of this chemoradiotherapy modality in locally advanced SCCHN patients.

Abstract
5-Fluorouracil (5-FU) and capecitabine alone and in combination with irinotecan/oxaliplatin are clinically active in the treatment of colorectal and other solid tumors. Studies of the antitumor activity and toxicity of capecitabine or irinotecan alone and in combination with each other, were compared with 5-FU and raltitrexed in human tumor xenografts of colorectal and squamous cell carcinoma of the head and neck using clinically relevant schedules. Antitumor activity and toxicity were evaluated in nude mice bearing human colon carcinomas of HCT-8 and HT-29 and in head and neck squamous cell carcinomas of A253 and FaDu xenografts using the maximum tolerable dose of single-agent capecitabine, 5-FU, or raltitrexed, or each of the drugs in combination with irinotecan. Mice were treated with capecitabine and irinotecan alone or in combination using 2 different schedules: (1) capecitabine orally once a day for 7 days and a single dose of irinotecan (50 mg/kg intravenously [I.V.]), with each drug alone or in combination, and (2) capecitabine orally 5 days a week for 3 weeks and irinotecan 50 mg/kg (I.V. injection) once a week for 3 weeks, with each drug alone or in combination. For comparative purposes, the antitumor activity of single-agent capecitabine, 5-FU, or raltitrexed, or each drug in combination with irinotecan was carried out at its maximum tolerated dose (MTD) using a 3-week schedule. Results indicated that HT-29 and A253 xenografts were de novo resistant (no cure) to capecitabine and irinotecan alone at the MTD, whereas HCT-8 and FaDu xenografts were relatively more sensitive, yielding 10%-20% cures. The combination of irinotecan/capecitabine was much more active than either drug alone against all 4 tumor models. The cure rates were increased from 0 to 20% in A253 and HT-29 xenografts and from 10%-20% to 80%-100% in HCT-8 and FaDu tumor xenografts, respectively. Irinotecan/capecitabine had clear advantage over irinotecan/5-FU and irinotecan/raltitrexed in efficacy and selectivity in that they were more active and less toxic. The extent of synergy with irinotecan/capecitabine appears to be tumor-dependent and independent of the status of p53 expression. The potential impact of the preclinical results on clinical practice for the use of these drugs in combination needs clinical validation.

Abstract
Abstract
Cells in neoplasms evolve by natural selection. Traditional cytotoxic chemotherapies add further selection pressure to the evolution of neoplastic cells, thereby selecting for cells resistant to the therapies. An alternative proposal is a benign cell booster. Rather than trying to kill the highly dysplastic or malignant cells directly, a benign cell booster increases the fitness of the more benign cells, which may be either normal or benign clones, so that they may outcompete more advanced or malignant cells in a neoplasm. In silico simulations of benign cell boosters in neoplasms with evolving clones show benign cell boosters to be effective at destroying advanced or malignant cells and preventing relapse even when applied late in progression. These results are conditional on the benign cell boosters giving a competitive advantage to the benign cells in the neoplasm. Furthermore, the benign cell boosters must be applied over a long period of time in order for the benign cells to drive the dysplastic cells to extinction or near extinction. Most importantly, benign cell boosters based on this strategy must target a characteristic of the benign cells that is causally related to the benign state to avoid relapse. Another promising strategy is to boost cells that are sensitive to a cytotoxin, thereby selecting for chemosensitive cells, and then apply the toxin. Effective therapeutic and prevention strategies will have to alter the competitive dynamics of a neoplasm to counter progression toward invasion, metastasis, and death.

Abstract
Recently, we cloned a novel sulfatase domain-containing downregulated gene, HSulf-1, which modulates heparin-binding growth factor signaling in ovarian cancer. Based on the pilot data showing the loss of HSulf-1 in head and neck squamous cell carcinoma cell lines (SCCHN), we sought to employ SCCHN as a model to define the role of HSulf-1 in the molecular regulation of tumorigenicity. Three SCCHN lines (012SCC, WMMSCC, and 015SCC) had no detectable HSulf-1 mRNA. Clonal lines of HSulf-1-expressing 012SCC attenuated the activation of ERK/mitogen-activated protein kinase (MAPK) signaling mediated by fibroblast growth factor (FGF-2) and both ERK/MAPK and Akt signaling mediated by hepatocyte growth factor (HGF). Consistent with this downregulation, phosphorylation of HGF receptor, c-Met, which is frequently overexpressed in SCCHN, was also attenuated in HSulf-1 clonal 012SCC cell lines. HGF markedly enhanced the motility and migration of vector-transfected cells in a transwell invasion chamber. However, HGF-mediated motility and invasion was attenuated in HSulf-1 clonal 012SCC cell lines. In addition, transfected cells displayed significant growth inhibition concomitant with a decrease in mitogenicity, as measured by thymidine incorporation and increased sensitivity to staurosporine- and cisplatin-induced apoptosis. These data suggest that HSulf-1 normally functions as a negative regulator in cell growth and loss of HSulf-1 in SCCHN potentiates growth factor signaling, enhances motility, invasiveness and inhibits stress-induced apoptosis, with a resulting increase in tumorigenicity.

Abstract
BACKGROUND Thalidomide has been shown to have antiangiogenic effects in preclinical models as well as a significant antitumor effect in hematologic tumors such as multiple myeloma. The authors performed this Phase II study to determine the activity, toxicity profile, and antiangiogenic effect of thalidomide in patients with locoregionally recurrent or metastatic squamous cell carcinoma of the head and neck. METHODS Twenty-one patients with recurrent or metastatic squamous cell carcinoma of the head and neck were treated with single-agent thalidomide. All patients had received radiation therapy, and most had undergone surgery (95%) and/or chemotherapy (90%). Thalidomide was initiated at 200 mg;3>daily and increased to a target dose of 1000 mg daily. Patients continued treatment until disease progression, unacceptable toxicity, or death occurred. RESULTS All 21 patients eventually developed progressive disease. Median time to progression was 50 days (95% confidence interval, 28-70), with median overall survival time of 194 days (95% lower confidence boundary, 151), similar to the progression and survival times reported for this patient group with other agents. Thalidomide was generally well tolerated, with few patients experiencing Grades 3 to 4 toxicities. Serum vascular endothelial growth factor and basic fibroblast growth factor levels increased in six of seven patients, for whom paired serum samples were available and all of whom had progressive disease. CONCLUSIONS In this heavily pretreated population of patients with advanced squamous cell carcinoma of the head and neck, thalidomide does not appear to have single-agent antitumor activity. Further evaluation of the mechanism of action of thalidomide is indicated. Potentially, future evaluations of thalidomide may be performed in combination with other antiangiogenic or cytotoxic agents in patients with earlier stage disease or in patients with minimal residual disease.

Abstract
BACKGROUND To develop novel therapeutic approaches for patients with head and neck malignancies, poorly immunogenic murine models of squamous cell carcinoma (SCC) need to be defined. METHODS The phenotype, growth characteristics, and responsiveness to tumor-specific T-cell transfer of a spontaneously arising murine SCC (SCC VII) were characterized. RESULTS SCC VII expresses major histocompatibility complex (MHC) class I molecules yet is resistant to tumor-specific T-cell killing and relatively insensitive to killing mediated by lymphokine-activated killer (LAK) cells. Intradermal tumors are reproducibly established after vaccination of 5 x 10(4) cells, and systemic micrometastases are apparent after intravenous administration of 2.5 x 10(4) cells. Immunotherapy of 3-day lung metastases using tumor-specific T cells and systemic interleukin-2 (IL-2) was ineffective in reducing the number of metastases in vivo. CONCLUSIONS SCC VII is a poorly immunogenic murine squamous cell cancer, which represents an ideal model for preclinical testing of immunotherapeutic approaches for patients with SCC of the upper aerodigestive tract.

Abstract
Although surgery and radiotherapy result in a cure in 40% of all cancer patients, the remaining 60% of the patients die as a result of metastatic disease. For those patients cancer has to be considered as a systemic disease and cure from cancer will likely come from some type of systemic treatment. This article gives a brief overview of the achievements in the development of chemotherapy over the last 50 years and the new potential targets for further drug development.

Abstract
Forty-two patients with advanced head and neck cancer entered this phase II trial of long-term continuous 5-fluorouracil (5-FU) infusion at a dose of 300 mg/m2/day for a maximum of 16 weeks. Objective response rate was 15% in 41 evaluable patients. Median time to progression was 2.9 months, and median survival 4 months. Toxicity was generally mild. Reversible stomatic and hand-foot syndrome WHO grade III-IV was observed in 5 and 3 patients, respectively. Haematologic toxicity and emesis were less pronounced with no grade III-IV toxicity. One patient had to discontinue treatment because of ataxia. No catheter-related toxicity and no treatment-related mortality were observed. In the present study long-term continuous infusion of 5-FU has only modest activity in terms of response rate, but the activity is comparable with other single-agent regimens. The treatment is well tolerated, with minimal toxicity making it usable in a palliative situation.

Abstract
The transformation of normal cells into cancerous cells is an evolutionary process. Populations of precancerous cells reproduce, mutate, and compete for resources. Some of these mutations eventually lead to cancer. We calculate the probability of developing cancer under a set of simplifying assumptions and then elaborate these calculations, culminating in a simple simulation of the cell dynamics. The agent-based model allows us to examine the interactions of mutations critical for the development of cancer that are either evolutionarily neutral or selective. We can also examine the interaction of these mutations with a "mutator phenotype" derived from mutations that raise the mutation rate for the entire cell. The simulations suggest that there must be at least two selectively neutral mutations necessary for the development of cancer and that preventive treatments will be most effective when they increase this number. The model also suggests that selective mutations facilitate the development of cancer, so that the more selective mutations necessary for the development of cancer, the greater the chance of developing it.

Abstract
We performed a retrospective analysis on the effect of neoadjuvant chemotherapy with three cycles of methotrexate (100 mg/m2 on day 1), cisplatin (90 mg/m2 on day 1) and bleomycin (20mg/m2 on day 1-5) with 21 d gap between each cycle in 44 patients with advanced squamous cell carcinoma of the cheek, lip and tongue followed by surgery and adjuvant chemotherapy consisting of cisplatin (90 mg/m2 on day 1), Mitomycin C (6 mg/m2 on day 1) and 5-fluorouracil (1000 mg/m2 120 h continuous infusion from day 1) repeated every 3 weeks for three cycles. Following induction chemotherapy, complete response was observed in 11 out of 44 patients (25%), and a partial response in a further 28 patients (64%). The overall median survival of all patients was 29 months and those in stage III and stage IV were 30 and 15 months respectively (P< 0.001). The median duration of the time to relapse in patients who responded to adjuvant chemotherapy was 28 months. The main toxic effect was vomiting followed by hematological toxicity. No treatment-related deaths occurred. The regimen showed a significant response, encouraging median survival and a good tolerability profile.

Abstract
PURPOSE This study investigated the in vivo antitumor effects of electrochemotherapy (ECT) using electroporation and bleomycin in a hamster tongue cancer model to assess its clinical applicability. MATERIALS AND METHODS Twenty animals with chemically induced tongue cancer were divided into four experimental groups designated B-E-, B-E+, B+E-, and B+E+. The B+E+ and B+E- groups received an intraperitoneal injection of 100 microg bleomycin. Fifteen minutes after the injection, the B+E+ animals received electric pulses. The B-E+ group received only electric pulses. The B-E- group received neither bleomycin nor electric pulses. Each group received the same treatment twice. The antitumor effects were assessed based on tumor volume reduction and histologic findings. RESULTS The B+E+ group showed remarkable tumor volume reduction, decreasing an average to 8.8% of its original volume 14 days after the treatment. Complete loss of the protruding tumor was observed in two of the five animals. Histologically, the tumors of the B+E+ group consisted of severely degenerated tumor cells and desquamative keratinizing cells. No living cancer cells were detected in three animals. The B+E-, B-E+, and B-E- groups showed progressive tumor growth, exceeding 200% of initial tumor volume during the experimental period. CONCLUSION The current study showed remarkable antitumor effects of ECT with bleomycin in the hamster tongue cancer model. ECT with bleomycin may be clinically applicable to the treatment of oral cancer.
