1.  Correlation between clinical findings and magnetic resonance imaging for the assessment of local response after standard treatment in cervical cancer☆ 
The aim of our study is to evaluate the correlation between gynecological examination and magnetic resonance (MRI) findings for the assessment of local response in cervical cancer patients treated with radiotherapy/chemotherapy (RT/ChT).
Patients and methods
This study is a retrospective review of 75 consecutive cervical cancer patients from April 2004 to November 2009 treated with RT/ChT. Clinical and radiological data were subsequently analyzed. Patient's median age was 51 with a FIGO stage from Ib to IVb. Individualized RT/ChT was administered with a median dose of 45 Gy. Sixty-three patients received a complementary brachytherapy. Seventy-one patients received chemotherapy on a weekly basis. Gynecological exam was performed 3 months and 6 months after treatment and these findings were compared to MRI results at the same time.
Statistic analysis
We used the Spearman's Rho test to determine the correlation level between the clinical and radiological methods.
A correlation of 0.68 (60%) was observed between the clinical and MRI findings at 3 months with a further increase of up to 0.86 (82.6%) at 6 months. In the few cases with a poor correlation, the subsequent assessment and the natural history of the disease showed a greater value of the clinical exam as compared with the MRI findings.
Physical exam remains an essential tool to evaluate the local response to RT/ChT for cervical cancer. The optimal clinical radiological correlation found at 6 months after treatment suggests that the combination of gynecological examination and MRI are probably adequate in patient monitoring.

2.  Two-Stage Phase I Dose-Escalation Study of Intratumoral Reovirus Type 3 Dearing and Palliative Radiotherapy in Patients with Advanced Cancers 
To determine the safety and feasibility of combining intratumoral reovirus and radiotherapy in patients with advanced cancer and to assess viral biodistribution, reoviral replication in tumors, and antiviral immune responses.
Experimental Design
Patients with measurable disease amenable to palliative radiotherapy were enrolled. In the first stage, patients received radiotherapy (20 Gy in five fractions) plus two intratumoral injections of RT3D at doses between 1 × 108 and 1 × 1010 TCID50. In the second stage, the radiotherapy dose was increased (36 Gy in 12 fractions) and patients received two, four, or six doses of RT3D at 1 × 1010 TCID50. End points were safety, viral replication, immunogenicity, and antitumoral activity.
Twenty-three patients with various solid tumors were treated. Dose-limiting toxicity was not seen. The most common toxicities were grade 2 (or lower) pyrexia, influenza-like symptoms, vomiting, asymptomatic lymphopenia, and neutropenia. There was no exacerbation of the acute radiation reaction. Reverse transcription-PCR (RT-PCR) studies of blood, urine, stool, and sputum were negative for viral shedding. In the low-dose (20 Gy in five fractions) radiation group, two of seven evaluable patients had a partial response and five had stable disease. In the high-dose (36 Gy in 12 fractions) radiation group, five of seven evaluable patients had partial response and two stable disease.
The combination of intratumoral RT3D and radiotherapy was well tolerated. The favorable toxicity profile and lack of vector shedding means that this combination should be evaluated in newly diagnosed patients receiving radiotherapy with curative intent.

5.  258 A Novel Therapeutical Option in Resistant Ganglionar and Cutaneous Tuberculosis 
Transfer factor was first described in 1955 and constitutes a Dialyzable Leukocyte Extract. It has been widely used in several infectious diseases and malignancies with satisfactory results. Although not yet fully clarified, among the mechanisms of action the most accepted is the enhancement of the cellular immunity.
We tested transfer factor in a 1 year old and 3 months patient diagnosed with Ganglionar Tuberculosis. 1 week after the administrarion of the Bacillus Calmette-Guérin vaccination, the present developed fever, cervical, submandibular, supraclavicular, inguinal and axillary lymphadenopathy. Later on the patient devoloped cutaneous clinical manifestations of tuberculosis such as scrofuloderma, fistulas, hypertrophic scars and ultimately, queloids. The patient had previously undergone short-term strictly supervised treatment for tuberculosis with very poor results. When the treatment was first administered, the patient had the following data: Total White Blood Count 12.9 Lymphocytes: 29% (12–46) CD3: 26.3% (59–90) T helper Cells (CD3/CD4) 21.6% (42–58) Cytotoxic T cells (CD3/CD8) 5.1% (17–33) Natural Killer Cells (CD56) 2.1% (3–7) B cells (CD19) 67.6 % (0–10).
At the end of the treatment, the patient´s immune system was enhanced in terms of cell count and improval of skin manifestations. Total White Blood Count 6.5 Lymphocytes: 51.3% CD3: 48.5% T helper cells (CD3/CD4) 31.2% Cytotoxic T Cells (CD3/CD8) 14.6% Natural Killer cells (CD56) 12.2% B cells (CD19) 985%. Cicatrization process was improved, with involution of skin lesions os scrofuloderma and fistulas. Lymphadenopathy was no longer encountered. We have followed the patient for a year and half and no relapses have been encountered.
We consider Transfer Factor a valuable option as adyuvant therapy in cases of ganglionar and cutaneous tuberculosis refractory to conventional treatments. To our knowledge, this is the first report of a case of the disease treated satisfactorily with transfer factor.

6.  Fluorescence in situ hybridization gene amplification analysis of EGFR and HER2 in patients with malignant salivary gland tumors treated with lapatinib 
Head & neck  2009;31(8):1006-1012.
Gene amplification status of the epidermal growth factor receptor (EGFR) and the human epidermal growth factor receptor 2 (HER2) were analyzed and correlated with clinical outcome in patients with progressive malignant salivary glands tumors (MSGT) treated with the dual EGFR/Her2 tyrosine kinase inhibitor lapatinib
Fluorescence in situ hybridization (FISH) analysis for both EGFR and HER2 gene amplification was performed successfully in the archival tumor specimens of 20 patients with adenoid cystic carcinomas (ACC) and 17 patients with non-ACC, all treated with lapatinib.
For ACC, no EGFR or HER2 amplifications were detected. For non-ACC, no EGFR gene amplifications were detected but 3 patients (18%) were HER2 amplified and all had stained 3+ for both EGFR and HER2 by immunohistochemistry (IHC) in their archival specimens. Two of these patients had time-to-progression (TTP) durations of 8.3 months and 18.4 months respectively. Interestingly, patients with low and high HER2/chromosome-specific centromeric enumeration probe (CEP) 17 ratio had a prolonged TTP than those with moderate ratios for both ACC and non-ACC subtypes.
HER2 to CEP17 FISH ratio may predict which patients with MSGT have an increased likelihood to benefit from lapatinib. The finding of HER2:CEP17 ratio as a predictive marker of efficacy to lapatinib warrants further investigation.
