    [Show abstract] [Hide abstract] ABSTRACT: Objective: To evaluate whether plasma cell-free DNA (cfDNA) was related to clinical outcome in inoperable stage I non-small cell lung cancer (NSCLC) patients undergoing stereotactic body radiotherapy (SBRT). Materials and methods: Plasma cfDNA was assessed at baseline, before the last day and 45 days after the end of SBRT, in 22 NSCLC patients. Twenty-two healthy controls were also evaluated. Results: Plasma cfDNA was higher in patients than in controls. An association with unfavourable disease-free survival was found for continuous baseline cfDNA increments (HR = 5.9, 95%CI: 1.7-19.8, p = 0.04). Conclusion: Plasma cfDNA may be a promising prognostic biomarker in high-risk NSCLC patients.

    [Show abstract] [Hide abstract] ABSTRACT: The paper by Rachidi et al. suggests that antiplatelet drugs may play a role in ameliorating the clinical outcome in a large series of patients with head and neck cancer managed with either surgery or radiation. Our data, as well as confirming the results observed by the authors, enhance their clinical relevance pointing out the effect of antiplatelet drugs in terms of locoregional control in the setting of patients with advanced head and neck cancer managed with definitive chemo-radiotherapy.

  • [Show abstract] [Hide abstract] ABSTRACT: Objectives The aim of this study was to assess the efficacy of IMRT with concomitant boost simultaneous integrated boost-intensity modulated radiotherapy (SIB-IMRT) compared with conventional radiation in the setting of sequential chemoradiotherapy (induction chemoradiotherapy(ICRT)) for patients with advanced oropharynx cancer (OPC).Materials and methods A single-institutional retrospective review was conducted on 84 patients (conventional radiation, n = 36; SIB-IMRT, n = 48) with stage III and IV OPC, who underwent definitive ICRT from 2002 to 2012. The study endpoints included overall survival (OS) and locoregional control (LRC).Results The median follow-up of the matched cohorts resulted similar (30 months for 3D-radiation technique versus 37 months for IMRT), and baseline characteristics were generally balanced between the two groups. However, patients managed with conventional radiation were less likely to have positron emission tomography-computed tomography (PET-CT) for staging and to receive induction chemotherapy with TPF. A multivariate Cox proportional hazard model showed that OS and LRC were associated with several known prognostic factors, along with radiation modality (SIB-IMRT versus conventional radiation, hazard ratio 0·27, p = 0·004; hazard ratio 0·31, p = 0·006; for OS and LRC, respectively).Conclusions The adoption of SIB-IMRT versus conventional radiation may produce a clinical benefit in OS and LRC among patients receiving ICRT for advanced OPC.

  • [Show abstract] [Hide abstract] ABSTRACT: Purpose To retrospectively assess toxicity and outcome of re-irradiation with stereotactic body radiation therapy (SBRT) in patients with recurrent or persistent non-small cell lung cancer (NSCLC), who were previously treated with radical radiation therapy (50-60 Gy). The secondary endpoint was to investigate whether there are dosimetric parameter predictors of severe radiation toxicity. Methods and Materials The analysis was conducted in 17 patients with “in-field” recurrent/persistent centrally located NSCLC, who underwent re-irradiation with SBRT. SBRT consisted of 30 Gy in 5 to 6 fractions; these prescriptions would be equivalent for the tumor to 37.5 to 40 Gy, bringing the total 2-Gy-per-fraction cumulative dose to 87 to 100 Gy, considering the primary radiation therapy treatment. Actuarial analyses and survival were calculated by the Kaplan-Meier method, and P values were estimated by the log-rank test, starting from the date of completion of SBRT. Dosimetric parameters from the subgroups with and without grade ≥3 pulmonary toxicity were compared using a 2-tailed Student t test. Results The median follow-up was 18 months (range, 4-57 months). Only 2 patients had local failure, corresponding to a local control rate of 86% at 1 year. The Kaplan-Meier estimates of overall survival (OS) rates at 1 and 2 years were 59% and 29%, respectively; the median OS was 19 months. Four patients (23%) experienced grade 3 radiation pneumonitis, and 1 patient developed fatal pneumonitis. One patient died of fatal hemoptysis 2 months after the completion of SBRT. Unexpectedly, heart maximum dose, D5 (minimum dose to at least 5% of the heart volume), and D10 were correlated with risk of radiation pneumonitis (P<.05). Conclusions Re-irradiation with SBRT for recurrent/persistent centrally located NSCLC achieves excellent results in terms of local control. However, the high rate of severe toxicity reported in our study is of concern.

    [Show abstract] [Hide abstract] ABSTRACT: Objectives. Retrospective review of our experience using intensity-modulated radiotherapy with simultaneous integrated boost (SIB-IMRT) combined with chemotherapy as the primary treatment of locoregionally advanced larynx and hypopharynx cancers. Materials and Methods. Between September 2008 and June 2012, 60 patients (26 with larynx and 34 hypopharynx cancers) were treated. Our policy was to offer SIB-IMRT plus concurrent cisplatin to patients affected by larynx cancer stage T3N0-N1 and NCT with TPF (docetaxel/cisplatin/fluorouracil) followed by SIB-IMRT to patients with larynx cancer stage T2-4N2-3 or hypopharynx cancer T2-4N0-3. SIB-IMRT consisted in a total dose of 70.95 Gy (2.15 Gy/fraction, 5 fractions/week) to the gross primary and nodal disease and differentiated dosages for high risk and low risk nodal regions. Results. Complete remission was achieved in 53/60 (88%) of patients. At a median follow up of 31 months (range 9–67), the rate of overall survival and locoregional control with functional larynx at 3 years were 68% and 60%, respectively. T stage (T1–3 versus T4) resulted in being significant for predicting 3-year freedom from relapse (it was 69% and 35%, resp., for T1–T3 and T4 tumors; ), while site of primary disease (larynx versus hypopharynx) was not significant (). Conclusion. Our results indicated that combining SIB-IMRT with induction chemotherapy or concurrent chemotherapy is an effective treatment strategy for organ preservation in advanced larynx/hypopharynx cancer.

    [Show abstract] [Hide abstract] ABSTRACT: Concurrent chemo-radiotherapy is demonstrately superior to sequential chemo-radiotherapy in the treatment of advanced Non-Small-Cell Lung Cancer not suitable for surgery. Docetaxel is considered to enhance the cytotoxic effect of radiotherapy on the tumour cells. Tomotherapy (HT) is a novel radiotherapeutic technique, which allows the delivery of Image Guided-IMRT (IG-IMRT), with a highly conformal radiation dose distribution.The goal of the study was to estimate tolerability of Docetaxel concurrent with IMRT and to find the maximum tolerated dose of weekly Docetaxel concurrent with IMRT delivered with HT Tomotherapy after induction chemotherapy with Cisplatin and Docetaxel in patients affected with stage III Non-Small Cell Lung Cancer. We designed a phase I, dose-finding study to determine the dose of weekly Docetaxel concurrent with Tomotherapy after induction chemotherapy, in patients affected by Non-Small Cell Lung Cancer with Stage III disease, not suitable for surgery. Concurrent weekly Docetaxel and Tomotherapy are feasible; we did not reach a maximum tolerated dose, because no life-threatening toxicity was observed, stopping the accrual at a level of weekly docetaxel 38 mg/m2, a greater dose than in previous assessments, from both phase-I studies with weekly docetaxel alone and with Docetaxel concomitant with standard radiotherapy. Concurrent weekly Docetaxel and Tomotherapy are feasible, and even with Docetaxel at 38 mg/m2/week we did not observe any limiting toxicity. For those patients who completed the combined chemo-radio treatment, median progression-free survival (PFS) was 20 months and median overall survival (OS) was 24 months.

  • [Show abstract] [Hide abstract] ABSTRACT: We have previously shown the feasibility of delivering high doses of radiotherapy in malignant pleural mesothelioma (MPM) patients who underwent radical pleurectomy/decortication (P/D) or surgical biopsy. In this report, we present the long-term results of MPM patients treated with radical P/D followed by high doses of radiotherapy. Twenty consecutive MPM patients were enrolled in this prospective study and underwent radical P/D followed by high dose radiotherapy. The clinical target volume was defined as the entire hemithorax excluding the intact lung. The dose prescribed was 50Gy in 25 fractions. Any FDG-avid areas or regions of particular concern for residual disease were given a simultaneous boost to 60Gy. Nineteen patients received cisplatin/pemetrexed chemotherapy. Kaplan-Meier analysis was used to calculate rates of overall survival (OS), progression-free survival (PFS), and loco-regional control (LRC). The median follow-up was of 27 months. The median OS and PFS were 33 and 29 months, respectively. The median LRC was not reached. The Kaplan-Meier estimates of OS at 2 and 3 years were 70% and 49%, respectively. The estimates of PFS at 2 and 3 years were 65% and 46%, respectively. The estimates of LRC at 2 and 3 years were 68% and 59%, respectively. The predominant pattern of failure was distant: 7 patients developed distant metastases as the first site of relapse, whereas only 3 patients experienced an isolated loco-regional recurrence. No fatal toxicity was reported. Five Grades 2-3 pneumonitis were documented. High dose radiation therapy following radical P/D led to excellent loco-regional control and survival results in MPM patients. A median OS of 33 months and a 3-year OS rate of 49% are among the best observed in recent studies, supporting the idea that this approach represents a concrete therapeutic option for malignant pleural mesothelioma.

  • [Show abstract] [Hide abstract] ABSTRACT: : This study aimed to assess the safety of high doses of radiation delivered with tomotherapy to the intact lung after radical pleurectomy/decortication or biopsy for malignant pleural mesothelioma (MPM). : Twenty-eight patients were enrolled in this prospective study and underwent adjuvant or definitive tomotherapy after radical pleurectomy/decortication (n = 20) or pleural biopsy (n = 8) for MPM. The dose prescribed to the planning target volume, defined as the entire hemithorax, including chest-wall incisions and drain sites and excluding the intact lung, was 50 Gy delivered in 25 fractions. All patients underwent fluorodeoxyglucose-positron emission tomography for staging after surgery. Any fluorodeoxyglucose-avid areas or regions of particular concern for residual disease were given a simultaneous boost of radiotherapy to 60 Gy. Specific lung dosimetric parameters were reported. Toxicity was graded using the modified Common Toxicity Criteria version 3.0. : The median follow-up was of 19 months (range, 6-29 months). Five patients (17.8%) experienced severe respiratory symptoms corresponding to grade 2 pneumonitis in three cases, and grade 3 pneumonitis in two cases. No fatal respiratory toxicity was reported. Controlateral lung V5 was strongly correlated with the risk of pneumonitis. Patients who developed grade 2 and 3 pneumonitis had a higher controlateral lung V5 (mean V5=32%) than those without pneumonitis (mean V5=17%) (p=0.002). Other two grade 3 toxicities were registered: one severe pain to the chest wall, and one severe thrombocytopenia. : Tomotherapy allows the safe delivery of high dose of radiation to the hemithorax of MPM patients with intact lung.

    [Show abstract] [Hide abstract] ABSTRACT: The present study evaluated toxicity, local control, and survival in patients with relapsed high-grade glioma after surgery and external beam radiation therapy and treated with re-operation and GliaSite brachytherapy. Between 2006 and 2008, 15 patients with recurrent high-grade glioma underwent re-operation and GliaSite brachytherapy. Ten patients were males and 5 females. Median age was 40 years (range, 20-71). Karnofsky performance status was ≥70. All patients but one received GliaSite irradiation of the surgical cavity wall at the dose of 4500 cGy at a depth of 1 cm. No severe acute side effects were observed during GliaSite brachytherapy. Pathologically documented, symptomatic late radiation necrosis was observed in 3 patients (20%); 2 subsequently died of further complications. Two patients were alive at a median follow-up 13 months (range, 1-30). Median overall survival after GliaSite brachytherapy was 13 months. Patients with recurrent high-grade glioma can be treated with additional surgery and GliaSite brachytherapy, delivering 4500 cGy at 1 cm depth without significant acute side effects but with a significant rate (20%) of late radiation necrosis, resulting in 13% of treatment-related deaths. Compared with the literature, survival results in our study appear to be satisfactory, but they may be related to patient selection criteria. Re-intervention followed by GliaSite brachytherapy should not be offered as a standard treatment for recurrent high-grade glioma, because of the high rate of late complications, treatment-related deaths, and high treatment costs.

  • [Show abstract] [Hide abstract] ABSTRACT: To evaluate the outcome of Undifferentiated Nasopharyngeal Carcinomas (UCNT) treated with intensity-modulated radiation therapy with Simultaneous Integrated Boost (SIB), following induction chemotherapy. Between January 2006 and June 2009, 52 patients with stage II B-IVA/B UCNT were treated either with linac-IMRT or Tomotherapy. All patients were scheduled to receive three cycles of cisplatin based neoadjuvant chemotherapy. With a median follow-up of 38.5 months (range 12.3-64.1), 3 year overall survival (OS), disease-free survival (DFS), and DFS by T2a-2b and T3-T4-stage were 95.0%, 84.6%, 89.0%, and 78.0%, respectively. At multivariate analysis, none of the examined prognostic factors reported statistical significance. N-classification was not a significant predictive factor for either OS or development of distant metastases. T-stage alone had a borderline effect on DFS and development of metastases. No difference between Tomotherapy and linac-IMRT emerged in terms of loco-regional control and development of severe, acute, and late toxicities. The most significant severe, acute toxicities were grade 3 (32.7%) and grade 4 (7.7%) mucositis. No grades 3 and 4 late toxicities were observed. The most commonly observed late effect was xerostomia, 11.5% patients complained grade 2 xerostomia. The severity of grade 2 xerostomia diminished over time with only four patients not improving salivation. IMRT-SIB following neoadjuvant chemotherapy was very satisfactory in terms of local control, regional control, DFS and OS rates in patients with stage IIB to IVB UCNT. In our experience, adding concurrent chemotherapy to IMRT after neoadjuvant chemotherapy in loco-regional widespread disease resulted to be the indicated approach.

    [Show abstract] [Hide abstract] ABSTRACT: The role of low doses of cisplatin and concomitant postoperative radiotherapy in high risk head and neck squamous cell carcinoma has not yet been defined. Patients treated with definitive surgery, who had histological evidence of involvement of more than 2 lymph nodes, extracapsular extension of disease, perineural and/or intravascular invasion, involved or close surgical margins, received postoperative radiotherapy plus 75 mg/m(2) of cisplatin every 3 weeks during the radiotherapy cycle. The primary endpoints were to evaluate treatment compliance and overall, cause-specific, and disease-free survival. A total of 142 patients were enrolled. With a median follow-up of 40 months, 5-year overall survival was 68%, cause-specific survival 78% and disease-free survival 82%. At multivariate analysis surgical margins status and extracapsular lymph node invasion were the only statistically significant prognostic factors. Fifty-three percent of the patients developed severe mucositis and 14% hematologic toxicity of grade 3. The 3 planned concomitant chemotherapy cycles were delivered to 48% of the patients. Postoperative radiotherapy and concomitant low-dose cisplatin was an effective treatment in high risk head and neck patients. The total toxicity observed was lower compared with that reported with higher doses of cisplatin, although the delivery of all the 3 planned chemotherapy cycles was challenging. The distant failure rate was high, which was an unsatisfactory result.

    [Show abstract] [Hide abstract] ABSTRACT: Leiomyosarcoma of the parotid gland is a rare tumor with only six cases reported in the english literature. To date, the association of this rare tumor with HIV infection has never been reported. We report the first case of a 19-year-old Caribbean woman affected by leiomyosarcoma of the parotid gland and HIV infection. Surgery, radiotherapy and chemotherapy used in this patient did not provide a good result in terms of overall survival. Intercurrent disease, opportunistic infection and chemotherapy cross-reaction have not been reported during this treatment regimen. The ability to use combined modality interventions in patients with secondary malignancies and immunosuppression requires further study with focus on both tolerance and efficacy.

  • [Show abstract] [Hide abstract] ABSTRACT: The present prospective study seeks to evaluate overall and disease free survival, response and organ preservation rate, and toxicity of an intensive chemotherapy regimen (CT) followed by unconventional radiotherapy (RT) in patients with locally advanced operable head and neck cancer. Between January 1998 and December 2006 (June 2005), 115 patients with locally advanced, operable head and neck cancer were evaluated. A total of 333 cycles of neoadjuvant CT (cisplatin-5FU, days 1, 14, 28) followed by hyperfractionated/accelerated radiotherapy were given to 108 patients. A total of 108 patients were evaluable and received the planned CT-RT treatment. Two months after the end of RT, 97.2% of patients had a clinical complete remission of the primary and 67.5% of the neck node site. The overall survival was 55% and cause-specific survival was 73% at 5 years. Of the 33 relapsed patients, 12 recurred only at the primary site and 10 patients had distant metastases. The overall organ preservation rate was 73.5%. The chemotherapy regimen reported an overall cardiotoxicity from 5FU in 14% of patients, with severe toxicity in 3%. The radiotherapy schedule developed 84% of Grade 3-4 mucositis in the observed patients. The accelerated CT-RT regimen is able to achieve a high rate of larynx preservation, a good tolerability, and a satisfactory cause-specific overall survival.

    [Show abstract] [Hide abstract] ABSTRACT: Despite macroscopically radical surgery and combined adjuvant chemoradiation recurrence of malignant glioma remains a certainty. About 80% of patients experience a tumor recurrence within 2 cm of the resection margin. Only a select group of patients with recurrent malignant gliomas are candidates for reoperation, but in spite of further adjuvant therapy, long-term survival is rare. The GliaSite® RTS was developed in an attempt to allow an additional radiation dose to be delivered in a way that maximizes the patient's quality of life while delivering a radiation dose to the tissue at greatest risk of recurrence. This study reports our experience with GliaSite® on 12 patients with recurrent high grade gliomas. The median radiation dose delivered was 46.5 Gy (range 45-60 Gy) to an average depth of 1 cm from the surgical cavity wall. Mild side effects post lotrex infusion were easily managed with drug therapy. One case of late symptomatic radiation necrosis was pathologically documented and a second case radiologically suspected. At the time of this analysis (median follow up 8.4 months, range 1-14 months) two patients died after 12 months from GliaSite® treatment for disease progression. These preliminary data need to be confirmed by a larger patient population with more information on the progression-free survival and overall survival. Our preliminary results confirm that brachytherapy treatment with GliaSite® is safe, improves quality of life and reduces the radiation adverse effects versus external beam radiotherapy.
