Consolidation radiotherapy (cRT) in patients with stage I/II diffuse large B-cell lymphoma of the Waldeyer's ring (WR-DLBCL) in complete remission (CR) after induction chemotherapy (CHT) is often associated with relevant acute and chronic toxicity, and its impact on survival remains to be defined. A total of 184 patients in CR after anthracycline-based chemotherapy were retrospectively analyzed: 62 underwent CHT alone (CHT group), while 122 (66%) patients were referred to cRT (CHT + RT group). After a median follow-up of 54 months, 36 patients (20%) experienced relapse: 19% in the CHT group and 20% in the CHT + RT group. At the time of analysis 47 (76%) CHT patients and 97 (80%) CHT + RT patients were alive. Five-year overall survival (OS), disease-free survival (DFS) and lymphoma-specific survival (LSS) were 80%, 74% and 86%, respectively. Five-year OS was significantly prolonged in the CHT + RT group, while DFS and LSS were similar between groups. This discrepancy was attributed to a high percentage of deaths due to unrelated causes in CHT patients. cRT does not prolong LSS in patients with early-stage WR-DLBCL in CR after anthracycline-containing chemotherapy. An international confirmatory trial is warranted. © 2013 Informa UK, Ltd.

It is known that extranodal head and neck diffuse large B cell lymphomas (eHN-DLBCL) can affect various anatomical structures what is not well-known, however, is whether they differ in terms of clinical presentation and outcome. Clinical data of the multi-institutional series, the largest of its kind as yet, has been analysed with the aim of answering these open questions and providing long-term follow-up information. Data from 488 patients affected by stage I/II eHN-DLBCL was collected: 300 of the Waldeyer's Ring (WR), 38 of the parotid and salivary glands (PSG), 48 of the thyroid gland (TG), 53 of the nasal cavity and paranasal sinuses (NPS), 24 of the palate and oral cavity (POC) and 25 with more than one involved site. Different eHN-DLBCL arising have distinct characteristics at presentation. The intermediate high risk-modified IPI was 67 % in TG, 44 % in WR, 38 % in PSG and POC and 20 % in MS. The worst 5-year survival rate had TG-DLBCL (61 %) due to the 61 % of patients with a mIPI >1. The addition of radiotherapy (cRT) to remitters did not translate into a survival advantage (5-year disease-free survival of 67 % in the cRT group vs. 70 % in the other). Three of four central nervous system recurrences occurred in NPS-DLBCL. Survival of HN-DLBCL was inferior to nodal DLBCL. This study showed that eHN-DLBCL remitters have an inferior survival when compared to nodal DLBCL, and that the addition of cRT does not provide a survival advantage. Since the standard of care nowadays is chemo-immunotherapy, survival of these patients might have been improved. © 2013 Springer-Verlag Berlin Heidelberg.

Background and purpose Irradiation of the Pharyngeal Superior Constrictor Muscle (PSCM) seems to play a crucial role in radiation-related swallowing dysfunctions. Purpose of our study was to quantify operator-related variability in the contouring of PSCM on Computed Tomography (CT) scans and adherence with contours derived from MR images. Materials and methods Three sets of treatment planning CT and their corresponding MR images were selected. Contouring of the PSCM was performed using both a literature-based method, derived from literature review, and an optimized method, derived from Magnetic Resonance (MR) images thus obtaining "literature-based" and "optimized" contours. Each operator contoured the PSCM on CT scans according to both methods for three times in three different days. Inter- and intra-operator variability and adherence to a contour obtained from MR images (named "MR-derived" contour) were analyzed. Results Thirty-four operators participated and 612 contours were obtained. Both intra- and inter-operator variability and adherence to the "MR-derived" contour were significantly different between the two methods (p ≤ 0.05). The "optimized" method showed a lower intra- and inter-operator variability and a higher adherence to the "MR-derived" contour. Conclusions The "optimized" method ameliorates both operator-related variability and adherence with MR images. © 2014 Elsevier Ireland Ltd. All rights reserved.

Aims. To quantify radiation treatments for bone metastases from breast cancer in three Sicilian provinces (Messina, Catania, Ragusa) with respect to the general population and the incidence and prevalence of breast cancer in this macro-area in a 8-year period. Methods. All bone metastasis patients treated using radiotherapy in 8 radiation departments operating in the provinces of Messina, Catania and Ragusa were collected. Among these, metastases from breast carcinoma were analyzed according to year of irradiation. An analysis of breast cancer incidence and prevalence with respect to inhabitants in this macro-area was conducted using literature and census data. Results. From January 2004 to December 2011, irradiation was delivered in 4419 bone metastasis patients. Among these, 1617 had a primary breast cancer with a median treatment per year of 206.5 (range, 164-251); 211 patients were treated in 2004 and 206 in 2011. In 2004, there were 1,048,957 female residents in the three provinces and 1,065,422 in 2011. The reported breast cancer incidence and prevalence in Sicily was respectively 100.79/100,000 and 908.54/100,000 in 2004 and 108.41/100,000 and 1091.29/100,000 in 2010. Conclusions. There has been an increase in both incidence and prevalence of breast cancer in Sicily. Nevertheless, it seems that there was no increment in skeletal-related events requiring irradiation in such patients in eastern Sicily radiation departments.

Aims and background. Radiotherapy has remarkable success rates for the cure of patients affected by glottic carcinoma; local control rates are similar to surgery with lower morbidity and better functional results. Our aim was to determine local-regional control rates, overall survival, second cancer incidence, acute-late toxicity and prognostic factors in our series of T1 glottic cancer patients with radiation doses of 60 to 66 Gy. Functional results were not sufficient for statistical analysis. Methods and study design. A retrospective study was carried out of all T1N0 glottic carcinomas treated with radiation therapy between 1996 and 2006. To be eligible, patients had to have newly diagnosed cancer and had to be treated with a curative intent by radiation therapy alone. Ninety-eight patients satisfied the eligibility requirements: 85 patients had T1a disease; 13 patients were staged as T1b. Treatment was performed for all cases with a 6 megavoltage linear accelerator. The total dose prescribed varied from 60 to 66 Gy: 2 Gy/fraction, 1 fraction/day, 5 fractions/week. During treatment, a weekly clinical evaluation was performed; endoscopic examination was performed once every two weeks. After the treatment, a clinical, endoscopic and radiological follow-up was performed every three months for the first two years, every 6 months till the fifth year, and then once a year. Results. With a median follow-up of 41.5 months (range, 10-132; mean, 56.8), we registered 12 cases of local failures; 8 of them were successfully treated with salvage surgery (median time to relapse, 3-48 months). The local relapse rate was 12.2%, and disease-specific survival, taking into account salvage surgery, was 6%. Thirty-four deaths were registered: 2 for local progression, 2 for distant metastasis, 4 for a new primary cancer, and 26 for non-neoplastic causes. Five- and 10-year overall survival were respectively 85.8% and 69.4%. Four cases of lung cancer were detected in the upper aerodigestive tract in our series. In terms of acute-late toxicity, no grade 3-4 dermatitis, dysphagia or hoarseness occurred. Mild dermatitis and arythenoid edema were the most common causes of toxicity. Only one patient did not complete the treatment (60 Gy instead of the planned 66 Gy). Conclusions. Our series confirmed the primary role of radiation therapy for the cure of T1N0 glottic cancer. Outcomes were good in terms of local-regional control as well as overall toxicity. Radiation therapy can be offered to T1 glottic cancer patients as a valid alternative to surgery, with high rates of functional preservation.


Purpose: The authors report acute toxicity in 14 patients with locally advanced head and neck squamous cell carcinoma treated with radiotherapy and cetuximab. Materials and methods: Data collection was performed prospectively on patients treated from September 2007 to March 2009. Treatment consisted of 64.8-70 Gy radiotherapy in conventional fractions and cetuximab. Results: Two out of 14 patients did not complete the planned combined treatment; radiotherapy was temporarily suspended in six other patients. Seven of 12 patients received cetuximab until the end of radiotherapy. Treatment breaks were principally due to severe acute cutaneous or mucous toxicity. Any grade acneiform rash occurred in all patients. In-field G3-4 cutaneous toxicity occurred in five (36%) patients and G3-4 mucous toxicity in seven (50%). One patient died of sepsis. Conclusions: In our experience, severe acute toxic reactions are common in patients treated with radiotherapy and concurrent cetuximab, resulting in frequent breaks or incomplete treatment with potential reduction in disease control. © 2011 Springer-Verlag Italia.

The use of novel radiotherapy techniques is widely increasing, allowing clinicians to treat diseases that were previously difficult to treat with radiation therapy. Malignant pleural mesothelioma is a clear example of this clinical challenge. We describe our first experience with intensity-modulated radiotherapy technique which was used to treat a 73-year-old patient with multiple relapsing malignant pleural mesothelioma. Intensity-modulated radiation therapy has allowed to respect the QUANTEC (quantitative analyses of normal tissue effects in the clinic) dose constraints, patient has experienced a 14 months progression-free time, without relevant subacute or late lung toxicity.
