The introduction of highly active antiretroviral therapy (ART) has deeply modified the outcome of HIV patients by improving their overall survival and ameliorating their quality of life (QoL). The prolongation of these patients' survival has led to an increased risk of highly diffused non-infectious diseases, e.g., cardiovascular diseases, endocrine disease, neurological diseases, and cancer. The management of antiretroviral therapy and anticancer agents (AC) can be challenging, due to the possible drug-drug interactions (DDI) between AC and ART. For this reason, a multidisciplinary approach is always preferred as demonstrated by the GICAT (Italian Cooperation Group on AIDS and Tumors). This review aims to analyze the current scientific data regarding the possible effects of ART on the management of HIV-positive cancer patients and to evaluate the possible DDIs that must be taken into consideration when co-administrating ART and AC. A collaboration between all the involved professional figures, particularly infectious disease specialists and oncologists, represents the key to the correct managing of these patients in order to guarantee the best oncological outcome possible.

Objective: The study was aimed to investigate the role of radiotherapy (RT) as a risk factor for reactivation or worsening of symptoms in patients affected by rheumatoid arthritis (RA) PATIENTS AND METHODS: This is a single-center retrospective observational study on RA patients who developed cancer requiring RT during the course of the disease. The control group consisted of RA patients with cancer who did not undergo RT. In both groups, the disease activity was evaluated at baseline and at 6 and 12 months through the DAS28 index. A relapse was defined as an increase of >20% in DAS28. A radiotherapist evaluated total and daily doses and timing of radiation. Acute and late toxicity was defined as events occurring within 90 days from the start and more than 90 days after the completion of RT, respectively., Results: Seventy-two RA patients (38F/34M; mean age: 70±9 years; mean disease duration: 13±9 years), 29 (40.2%) of whom received radiotherapy (mean age 72.9±9 years), were enrolled. The most frequent malignancies were breast (27.2%), thyroid (9.8%), and skin (7%). Between radio-treated and non-radio-treated patients, no significant differences in RA reactivation (6/29 vs. 17/43; p=0.12) or mean exacerbation time (6.7 ± 4.9 months compared to 6.4 ± 4.1 months; p=0.78) were found. Overall, RT was well tolerated with low rates of both acute and late toxicity., Conclusions: In RA patients, RT was well tolerated and not associated with an increased risk of articular flares. Properly designed prospective clinical studies with a larger number of patients should be performed to confirm these data.

Objective: To assess changes of CT perfusion parameters (ΔPCTp) of cervical lymph node metastases from head and neck cancer (HNC) before and after radiochemotherapy (RT-CT) and their association with nodal tumor persistence., Patients and Methods: Eligibility criteria included HNC (Stage III-IV) candidates for RT-CT. Patients underwent perfusion CT (PCT) at baseline 3 weeks and 3 months after RT-CT. Blood volume (BV), blood flow (BF), mean transit time (MTT) and permeability surface (PS) were calculated. PET/CT examination was also performed at baseline and 3 months after treatment for metabolic assessment., Results: Between July 2012 and May 2016, 27 patients were evaluated. Overall, only 3 patients (11%) experienced tumor persistence in the largest metastatic lymph node. A significant reduction of all PCTp values (p<0.0001), except MTT (from 6.3 to 5.7 s; p=0.089), was observed at 3 weeks post-RT-CT compared to baseline. All PCTp values including MTT were significantly lower at 3-month follow-up compared to baseline (p<0.05). Moreover, a statistically significant association was observed between nodal tumor persistence and high BF values (p=0.045) at 3 months after treatment that did not occur for the other parameters., Conclusions: Our preliminary findings show that all PCTp except MTT are significantly reduced after RT-CT. High BF values at 3 months post-RT-CT are predictive of nodal tumor persistence.

Objective: To assess the association of clinicopathologic and molecular features with loco-regional recurrence (LRR) in post-mastectomy breast cancer patients with or without adjuvant radiotherapy (PMRT)., Patients and Methods: We retrospectively reviewed data of patients undergone to mastectomy followed or not by PMRT between January 2004 and June 2013. The patients were divided according to clinicopathologic and molecular sub-classification features. LRR and Cancer Specific Survival (CSS) were calculated using the Kaplan-Meier method; the prognostic factors were compared using long-rank tests and Cox regression model., Results: A total of 912 patients underwent to mastectomy of whom 269 (29.5%) followed by PMRT and 643 (70.5%) not; among the PMRT group, 77 underwent to the chest wall (CW) and 202 to the chest wall and lymphatic drainage (CWLD) irradiation. The median follow-up was 54 months (range, 3-118). No significant difference in terms of LRR and CSS was found between non-PMRT and PMRT group (p=0.175; and p=0.628). The multivariate analysis of LRR for patients who did not undergo PMRT showed a significant correlation with the presence of extracapsular extension (ECE) (p=0.049), Ki-67>30% (p=0.048) and triple negative status (p=0.001). In the PMRT group, triple negative status resulted as the only variable significantly correlated to LRR (p=0.006) at the multivariate analysis and T-stage also showed a trend to significance (p=0.073). Finally, no difference in LRR control was shown between CW and CWLD-PMRT (p=0.078)., Conclusions: After mastectomy ECE, a cut off of Ki-67>30% and triple negative status were strictly correlated with LRR regardless of clinicopathologic stage. PMRT has a positive impact in decreasing LRR in patients with this molecular profile. Besides, CW might represent a valid option for patients with one to three positive nodes.

Gastric cancer (GC) is the third leading cause of cancer death in both sexes worldwide, with the highest estimated mortality rates in Eastern Asia and the lowest in Northern America. However, the availability of modern treatment has improved the survival and the prognosis is often poor due to biological characteristics of the disease. In oncology, we are living in the "Era" of target treatment and, to know biological aspects, prognostic factors and predictive response informations to therapy in GC is mandatory to apply the best strategy of treatment.The purpose of this review, according to the recently published English literature, is to summarize existing data on prognostic aspects and predictive factors to response to therapy in GC and to analyze also others therapeutic approaches (surgery and radiotherapy) in locally, locally advanced and advanced GC. Moreover, the multidisciplinary approach (chemotherapy, surgery and radiotherapy) can improve the prognosis of GC. The purpose of this review, according to the recently published English literature, is to summarize existing data on prognostic aspects and predictive factors to response to therapy in GC and to analyze also others therapeutic approaches (surgery and radiotherapy) in locally, locally advanced and advanced GC. Moreover, the multidisciplinary approach (chemotherapy, surgery and radiotherapy) can improve the prognosis of GC.

Objective: Mantle cell lymphoma (MCL) is a non-Hodgkin lymphoma (NHL) featured by participation of the lymph nodes, spleen, blood and bone marrow with a short remission period to standard therapies and a median overall survival of 4-5 years., Patients and Methods: In this study, we compare the levels of bcl-1/JH fusion products detected by q-PCR in the concurrent peripheral blood (PB) and bone marrow (BM) aspirate samples from 7 patients with MCL., Results: In patients with moderate to high levels of bcl-1/JH copies, the results of q-PCR analysis of PB and BM aspirate samples correlate well. In patients with high levels of bcl-1/JH copies, instead, PB levels are a good indication of tumor burden. Finally, in patients with low levels of bcl-1/JH copies, the t(11;14) may be detected by identification of neoplastic cells., Conclusions: Our data suggest that PB can be reliably used in place of BM aspirate both for detection of translocation status during minimal residual disease monitoring and for a possible molecular relapse, especially in those patients who have moderate to high levels of bcl-1/JH copies. If these results will be confirmed on a wider number of MCL patients, future study will be required to address the issue.

Anaplastic thyroid carcinoma (ATC) is a very rare disease accounting for less than 2% of all thyroid malignancies and associated to a dismal prognosis. The median survival is between 3 to 9 months with less than 10% of patients alive at 3 years after the time of diagnosis. This low cure rate is due to the late clinical presentation as a bulky unresectable tumour mass often associated with synchronous lung metastases (20-50%). A multimodality treatment consisting in a radical surgery followed by radiotherapy and chemotherapy is reported to be associated with better clinical outcomes while young age (< 65 years), tumour size (< 6.5 cm) and absence of distant metastases at time of diagnosis are recognized as strong prognostic factors of survival. We report the case of a 65 year-old man who was referred to our hospital for an ATC which extended to the external right tracheal wall and muscolar layer of esophagus. The patient underwent radical thyroidectomy with bilateral neck dissection followed by 3 cycles of adjuvant chemotherapy (Cisplatin /Epirubicin) and subsequent radiochemotherapy with Cisplatin as radiosensitizer. At more than 6 years since diagnosis the patient is still alive without evidence of local recurrence or distant metastases. Therefore, aggressive multimodality treatment after radical surgery might improve clinical outcomes and perhaps should be tested in prospective clinical trials.

Cancer survivorship represents a new challenge in the third Millennium. In Europe the number of cancer survivors was estimated to be 17,8 million in 2008 and this number is growing. Recent improvements in cancer survival are largely due to earlier diagnosis and advancements in treatment. Despite having favorable effects on cancer survival, radiation therapy, surgery treatment and combination chemotherapy regimens can also cause long-term organ damage and functional disabilities. In this paper we review the most important aspects of long-term toxicities in otolaryngology cancer survivors patients.

Background: Traditional treatment for uveal melanoma is the enucleation of the eye with outcomes cosmetically unacceptable and loss of useful vision. Plaque brachytherapy, compared to enucleation, had the advantage to preserve the eye with outcomes cosmetically acceptable and preservation of vision., Patients and Methods: From July 1990 to December 2009 one hundred forty-two (142) patients (51 males and 91 females) with small to medium uveal melanoma were treated with 106Ru plaque brachytherapy. The patients underwent a complete staging before brachytherapy with indirect ophthalmoscopy and ultrasounds. Mean tumour thickness was 3.26 mm (1.6-6 mm). The dose scheduled was 80-100 Gy to the apex with a maximum dose of 800 Gy to the sclera., Results: One hundred forty-two have been treated, nine patients had lost the follow-up and drop out; 133 patients were assessed. Mean follow-up was 7.7 years (6 months-18 years). The overall survival at 5, 10 and 15 years was 92%, 85% and 78% respectively. Cancer fee survival was 95%, 90% and 83%, respectively at 5, 10 and 15 year. Radiation-induced toxicity was represented in 47 patients with a 5 year actuarial survival rate free from complications of 54%., Conclusions: 106Ru plaque brachytherapy is a valid approach for treatment of uveal melanoma. This technique is efficacy and safe, with a low toxicity profile.

Historically radiotherapy has always played a limited role for the treatment of HCC due to the low tolerance of the liver and the subsequent risk of radiation induced liver disease (RILD). Technologist advancements in radiation planning and treatment delivery such as Stereotactic Body Radiotherapy (SBRT) combined with Image Guided Radiotherapy (IGRT) has allowed us to further increase tumor dose while maximally sparing the surrounding not involved liver. Furthermore, together with the growing knowledge of radiobiological models in liver disease, several mono-institutional retrospective and prospective series are reporting very encouraging results. Therefore, radiotherapy might play a significant role for the treatment of unresectable HCC, alone or combined with other locoregional treatment such as transarterial chemoembolisation (TACE). The rationale for studying this technique is really strong and it should be tested in well designed prospective randomized clinical trials.

More than 60% of all cancer patients in Europe and the USA are older than 65 years at the time of diagnosis. Despite this, elderly patients are generally under-represented in clinical trials. There is a lack of clinical trials to drive evidence-based decision making in the elderly cancer patients. In this review, we address the most important issue surrounding the treatment of older cancer patients: comorbidity assessment.

The natural history of HIV infection has been greatly changed by the introduction of highly active antiretroviral therapy (HAART). As a consequence of improved immune function, the incidence of AIDS-defining cancers (ADCs), such as Kaposi's sarcoma, non-Hodgkin's lymphoma (NHL) and invasive cervical cancer, has significantly declined. On the contrary, non-AIDS-defining cancers (NADCs), such as hepatocellular carcinoma, anal cancer, lung cancer, colorectal cancer and Hodgkin's lymphoma, have gradually emerged as a major fraction of the overall cancer burden. The reasons are still partially unknown. Some of the increased risk may be explained by a high prevalence of cancer risk factors, such as smoking, alcohol consumption, human papilloma virus (HPV) infection and HCV infection among HIV-infected people. The role of immunosuppression in the development of NADCs is controversial, as several studies have not found a clear-cut evidence of an association between the degree of immunosuppression and the development of NADCs. Analogously, the impact of HAART is still not well defined. Future research should focus on the etiology of NADCs, in order to shed light on the pathogenesis of cancer and ultimately to work for prevention; moreover, additional studies should evaluate the best therapeutic approaches to NADCs and the impact of cancer screening interventions among HIV-infected people, in an effort to diagnose cancer at an earlier stage.

Introduction: Squamous cell carcinoma of the anus (SCCA) is a relatively uncommon cancer. In the HIV-positive patients the introduction of the highly active antiretroviral therapy (HAART) did not change the incidence of SCCA., Background and Objectives: This paper describes the Italian Cooperative Group on AIDS and Tumours (GICAT) experience on HIV-positive patients with SCCA. The purposes of this retrospective study were: first to describe the clinical presentation and outcome of HIV-positive patients with SCCA, second to compare them with the ones reported in the literature., Patients and Methods: Between July 2000 and March 2010 we retrospectively collected epidemiological, clinical and survival data from 65 patients with SCCA in HIV infection enrolled within the GICAT., Results: Fifty-three (81.5%) patients were male. The majority of patients (40%) were homosexual Forty-three patients (66.1%) were diagnosed with HIV before 1996. Thirty-five patients (54%) had CD4-positive cells count > 200 / mm3 and 28 patients (43%) had viral load > 50 cp / ml at the time of SCCA diagnosis. The median time difference between HIV and SCCA diagnosis was 120 months (range 10-282 months). Sixty-one patients (96.8%) received HAART at SCCA diagnosis. Fifty-two patients (80%) had performance status (PS) 0-1 at the time of SCCA diagnosis. Twenty-seven patients (41.5%) underwent surgery with curative intent. Thirty-five patients (53.9%) were given combined modality therapy (CMT) consisting of pelvic radiotherapy with concurrent chemotherapy. No grade 3/4 haematological or extra-haematological effects were observed in our patients., Conclusions: In summary, despite the retrospective nature of analysis, the absence of patient strict criteria of inclusion/exclusion, our data on HIV-positive patients with SCCA, compared both to general population and to small reports on HIV-positive patients present in the literature, are promising.

Background: The aim of our study was to evaluate the pattern of local failure after stereotactic body radiotherapy (SBRT) of non small cell lung cancer (NSCLC) lesions relating to different type of 18F-FDG positron emission tomography (PET) response., Methods: Thirteen NSCLC patients for a total of 15 lesions (primary early or locally advanced and metastases) underwent PET before and 6 months after SBRT. Maximum standard uptake value (SUVmax) <2.5 was considered as cut off for complete response (CR) while lesion reduction > or =50% with residual value above 2.5 for partial response (PR)., Results: With a median follow up of 30 months pre- and post-SBRT mean SUV max values were 8.2 (range 14.2-3.7) and 2.4 (range 12.9-0), respectively. No "in field recurrence" was observed while 3 cases of "out field recurrence" occurred as regional nodes progression at 7.8 and 14 months after treatment. Three years overall survival, local control and distant metastases free survival were respectively 66.7%, 63.3% and 44.4%. Actuarial 75% and 53.3% 3-year local control, 60% and 40% 3-years distant metastases free survival were observed for complete and partial PET response, respectively, after SBRT. Thereafter, 60% and 50% 3-year overall survival were observed for complete and partial response., Conclusions: Clinical results were significantly better for "responder" than "non responder" and for "complete" than "partial response" group. Moreover, our data seem to confirm that a significant subset of patients maintain a low metabolic activity without developing local relapse on longer follow up.

Background: The purpose of this study was to evaluate the ability of rectal suppository of hyaluronic acid to limit symptoms of acute radiation proctitis in patients with prostate cancer (PC)., Materials and Methods: From January 2011 to October 2011, 50 consecutive patients, undergoing radiotherapy with radical or adjuvant intent for PC, were invited to use rectal suppository of hyaluronic acid (HA: Cicatridina suppository, Farma-Derma s.r.l., Sala Bolognese, BO, Italy) daily, before radiation delivering. An historical group was used as an external control. Acute rectal toxicity was scored weekly according to RTOG criteria. Time to occurrence of acute rectal toxicity was taken as endpoint., Results: Compliance was good. Only 2% of HA treated patients had a G2 acute proctitis versus 7% of historical group, globally a difference was observed in rate of acute proctitis between the experimental arm and the control group: 32% in experimental arm versus 45% in control group (p = 0.08). A delay in the onset of acute rectal toxicity in patients treated with HA (p = 0.04) was showed., Conclusions: Our findings suggested the role of HA in reducing acute proctitis in prostate cancer patients treated with radiotherapy. Further trials are needed to confirm these results.
