Abstract
BACKGROUND This open-label, multicenter, phase Ib study assessed the safety and preliminary activity of duligotuzumab, a dual-action antibody that blocks ligand binding to human epidermal growth factor receptor 3 (HER3) and epidermal growth factor receptor, in combination with chemotherapy, in the first-line treatment of patients with recurrent/metastatic squamous cell cancer of the head and neck. METHODS On day 1, duligotuzumab at a dose of 1650 mg intravenously was combined with cisplatin at a dose of 100 mg/m2 and 5-fluorouracil at a dose of 1000 mg/m2 /day on days 1 to 4 in treatment arm A, or carboplatin (area under the curve, 6 mg/mL/min) and paclitaxel (at a dose of 200 mg/m2 ) in treatment arm B. Up to 6 cycles (21 days/cycle) were followed by duligotuzumab maintenance until disease progression or intolerable toxicity occurred. RESULTS Nine patients in arm A and 15 patients in arm B received a median of 6 cycles of chemotherapy, and a median of 11 cycles (arm A) and 9 cycles (arm B) of duligotuzumab. Dose-limiting toxicities occurred in 3 patients in arm A and 1 patient in arm B. Grade ≥ 3 treatment-related adverse events (graded according to graded according to National Cancer Institute Common Terminology Criteria for Adverse Events [version 4.0]) in ≥ 3 patients were neutropenia (5 patients), hypokalemia (4 patients), dehydration (3 patients), anemia (3 patients), and diarrhea (3 patients) in arm A, and neutropenia (8 patients), anemia (5 patients), febrile neutropenia (4 patients), leukopenia (3 patients), thrombocytopenia (3 patients), and hypomagnesemia (3 patients) in arm B. The chemotherapy dose was reduced in 19 of 24 patients. Sixteen patients (67%) demonstrated objective responses regardless of human papillomavirus status or neuregulin 1 (NRG1) mRNA expression (arm A: 2 confirmed complete responses and 4 confirmed partial responses; arm B: 2 confirmed complete responses and 8 confirmed partial responses). CONCLUSIONS Duligotuzumab in combination with cisplatin/5-fluorouracil or carboplatin/paclitaxel demonstrated encouraging activity in patients with recurrent/metastatic squamous cell cancer of the head and neck; an association with increased frequency and severity of select adverse events relative to historical data was suggestive of the potentiation of chemotherapy-related adverse events.

Abstract
AIM: To evaluate the diagnostic potential of Lugol's chromoendoscopy-guided confocal laser endomicroscopy (CLE) in detecting superficial esophageal squamous cell neoplasia (ESCN). METHODS Between December 2008 and September 2010, a total of 52 patients were enrolled at the Chinese PLA General Hospital in Beijing, China. First, Lugol's chromoendoscopy-guided CLE was performed in these patients and the CLE in vivo histological diagnosis was recorded. Then, chromoendoscopy-guided biopsy was performed in the same patients by another endoscopist who was blinded to the CLE findings. Based on the biopsy and CLE diagnosis, en bloc endoscopic resection was performed. The CLE in vivo diagnosis and the histological diagnosis of biopsy of ESCN were compared, using a histological examination of the endoscopic resection specimens as the standard reference. RESULTS A total of 152 chromoendoscopy-guided biopsies were obtained from 56 lesions. In the 56 lesions of 52 patients, a total of 679 CLE images were obtained vs 152 corresponding biopsies. The sensitivity, specificity, negative predictive value and positive predictive value of chromoendoscopy-guided CLE compared with biopsy were 95.7% vs 82% (P < 0.05), 90% vs 70% (P < 0.05), 81.8% vs 46.7% (P < 0.05), and 97.8% vs 92.7% (P > 0.05), respectively. There was a significant improvement in sensitivity, specificity, negative predictive value, and accuracy when comparing chromoendoscopy-guided CLE with biopsy. CONCLUSION Lugol's chromoendoscopy-guided CLE is a real-time, non-invasive endoscopic diagnostic technology; the accuracy of the detection of superficial ESCN is equivalent to or may be superior to biopsy histology.

Abstract
PURPOSE This study sought to determine the maximum tolerated dose (MTD) of oral etoposide in combination with radiotherapy in head and neck squamous cell carcinoma (HNSCC). PATIENTS AND METHODS Phase I, multicenter, open-labelled, non-comparative and dose escalating trial. Patients with locally advanced HNSCC were enrolled onto cohorts of escalating dose of etoposide. Oral etoposide was administered on five consecutive days every week for 7 weeks (7 treatment cycles) in combination with daily radiotherapy (70 Gy /35 fractions). Two dose levels (25 mg/day and 50 mg/day) of etoposide were planned and three to six patients were to be enrolled at each level according to the potential DLTs. RESULTS Fourteen patients were allocated to two dose levels: 25 mg/day (3) and 50 mg/day (11). Cisplatin was contra-indicated in all the patients included. Only one patient (50 mg/day) presents a grade 4 neutropenia (DLT), no other DLTs were observed. The most frequently adverse events (AEs) were radiomucositis. Two deaths before 3 months of end of treatment were not related to treatment. Seven patients were still alive with a median follow-up of 30 months (12-58 months). Nine patients had a complete response (CR) at 3 months after the radiotherapy; Among the 9 patients, 3 patients had a local relapse; one patient with local and distant relapse. CONCLUSION Due to only one DLT experienced, it is possible to a dose of 50 mg/day for phase II studies, however this should be considered with caution.

Abstract
BACKGROUND The vascular disrupting agent combretastatin-A4-phosphate (CA4P) demonstrated antitumour activity in preclinical studies when combined with radiation. METHODS Patients with non-small-cell lung cancer (NSCLC), prostate adenocarcinoma, and squamous cell carcinoma of the head and neck (SCCHN) received 27 Gy in 6 fractions treating twice weekly over 3 weeks, 55 Gy in 20 fractions over 4 weeks, and 66 Gy in 33 fractions over 6 weeks respectively. CA4P was escalated from 50 mg/m2 to 63 mg/m2. CA4P exposure was further increased from one to three to six doses. Patients with SCCHN received cetuximab in addition. RESULTS Thirty-nine patients received 121 doses of CA4P. Dose-limiting toxic effects (DLTs) of reversible ataxia and oculomotor nerve palsy occurred in two patients with prostate cancer receiving weekly CA4P at 63 mg/m2. DLT of cardiac ischaemia occurred in two patients with SCCHN at a weekly dose of 50 mg/m2 in combination with cetuximab. Three patients developed grade 3 hypertension. Responses were seen in 7 of 18 patients with NSCLC. At 3 years, 3 of 18 patients with prostate cancer had prostate-specific antigen relapse. CONCLUSIONS Radiotherapy with CA4P appears well tolerated in most patients. The combination of CA4P, cetuximab, and radiotherapy needs further scrutiny before it can be recommended for clinical studies.

Abstract
Boron neutron capture therapy (BNCT) provides highly targeted delivery of radiation through the limited spatial distribution of its effects. This translational research/phase I clinical trial investigates whether BNCT might be developed as a treatment option for squamous cell carcinoma of head and neck (SCCHN) relying upon preferential uptake of the two compounds, sodium mercaptoundecahydro-closo-dodecaborate (BSH) or L-para-boronophenylalanine (BPA) in the tumour. Before planned tumour resection, three patients received BSH and three patients received BPA. The (10)B-concentration in tissues and blood was measured with prompt gamma ray spectroscopy. Adverse effects from compounds did not occur. After BPA infusion the (10)B-concentration ratio of tumour/blood was 4.0 +/- 1.7. (10)B-concentration ratios of tumour/normal tissue were 1.3 +/- 0.5 for skin, 2.1 +/- 1.2 for muscle and 1.4 +/- 0.01 for mucosa. After BSH infusion the (10)B-concentration ratio of tumour/blood was 1.2 +/- 0.4. (10)B-concentration ratios of tumour/normal tissue were 3.6 +/- 0.6 for muscle, 2.5 +/- 1.0 for lymph nodes, 1.4 +/- 0.5 for skin and 1.0 +/- 0.3 for mucosa. BPA and BSH deliver (10)B to SCCHN to an extent that might allow effective BNCT treatment. Mucosa and skin are the most relevant organs at risk.

Abstract
BACKGROUND There is no standard treatment for inoperable recurrent or metastatic cancer of the uterine cervix. Retinoids and interferon, in combination with cytotoxic compounds, have been shown to be active in squamous cell carcinoma (SCC). This phase II trial sought to estimate the response rate and the tolerance to a 3-month treatment combining cisplatin, interferon-alpha (IFN-alpha) and all-trans-retinoic (tRA) or 13 cis retinoic acid (13Cis), in women with recurrent or metastatic cervical SCC. PATIENTS AND METHODS Between November 1994 and October 1996, 33 patients, who had previously received aggressive treatment, and with metastatic and/or bulky disease were enrolled: 22 received tRA(40 mg/m(2)/day), 11 received 13Cis (1 mg/kg/day) in combination with IFN-alpha (6.106 UI/day SC) for 84 days plus cisplatin (40 mg/m(2)IV, days 1, 28 and 56). RESULTS All patients were evaluable for response and/or toxicity. Toxicities were easily manageable and were never life-threatening, with major grade 3/4 vomiting (54%) and asthenia (54%). Seventeen patients (52%) stopped or reduced treatment because of toxicity or progression. Six objective responses (18%) were observed. No complete response was recorded. Median response duration was 4 months. Time to progression was 9 months [range 3.3 to 20.9] for responders and 7 months [range 1.7 to 32] for all patients. CONCLUSIONS Regarding toxicity, this regimen should no longer be recommended in previously treated, advanced uterine SCC. However, the consistent response rate reported here may warrant further investigations in an early setting. Retinoid-based treatment with cytokines remains a promising field of research.
