    ABSTRACT: Neoadjuvant chemotherapy (NAC) is widely used in locally advanced breast cancer (BC) treatment. The role of postmastectomy radiotherapy (PMRT) after NAC is strongly debated. The aim of our analysis was to identify major prognostic factors in a single-center series, with emphasis on PMRT. From 1997 to 2011, 170 patients were treated with NAC and mastectomy at our center; 98 cases (57.6%) underwent PMRT and 72 cases (42.4%) did not receive radiation. At a median follow-up period of 7.7 years (range 2-16) for the whole cohort, median time to locoregional recurrence (LRR) was 3.3 years (range 0.7-12.4). The 5-year and 10-year actuarial LRR rate were 14.5% and 15.9%, respectively. At the multivariate analysis the factors that significantly correlated with survival outcome were ≥4 positive nodes (HR 5.0, 1.51-16.52; P = 0.035), extracapsular extension (HR 2.18, 1.37-3.46; P = 0.009), and estrogen receptor positive disease (HR 0.57, 0.36-0.90; P = 0.003). Concerning LRR according to use of radiation, PMRT reduced LRR for patient with clinical T3 staged disease (P = 0.015). Our experience confirmed the impact of pathological nodal involvement on survival outcome. PMRT was found to improve local control in patients presenting with clinical T3 tumors, regardless of the response to chemotherapy.

    ABSTRACT: Meningiomas account for up to 20 % of all primary intracranial neoplasms; although the majority of these have a benign course, as many as 5-10 % can display more aggressive behavior and a higher incidence of disease progression. The benefit of immediate adjuvant radiotherapy is still being debated for atypical and malignant meningiomas. This study aimed to retrospectively assess prognostic factors and outcome in 68 patients with atypical and malignant meningiomas. Sixty-eight meningioma patients were treated with radiotherapy after initial resection or for recurrence, between January 1993 and December 2011. Surgery was macroscopically complete in 80 % of the patients; histology was atypical and malignant in 51 patients and 17 patients, respectively. Mean dose of radiotherapy was 54.6 Gy. Fifty-six percent of all patients received radiotherapy after surgical resection, 26 % at the first relapse, and 18 % at the second relapse. Median follow-up was 6.7 years, (range 1.5-19.9 years). The 5- and 10-year actuarial overall survival (OS) rates were 74.1 and 45.6 %, respectively. At univariate analysis age >60 years, radiotherapy dose >52 Gy showed statistical significance, (p = 0.04 and p = 0.03, respectively). At the multivariate analysis radiotherapy dose >52 Gy maintained the statistical significance, (p = 0.037). OS of patients treated with radiotherapy at diagnosis was longer than the survival of patients treated with salvage radiotherapy; however this difference did not reach statistical significance when tested for the entire series or for the subgroups of grade 2 and grade 3 patients. The 5- and 10-year disease-free survival (DFS) rates were 76.5 and 69.5 %, respectively, and were significantly influenced by size >5 cm (p = 0.04) and grading (p = 0.003) on univariate analysis. At multivariate analysis, size and grading both remained significant prognostic factors, p = 0.044 and p = 0.0006, respectively. Grade ≤ 2 acute side effects were seen during radiotherapy treatment in 16 % of the patients, with no ≥ grade 3 acute toxicity, based on the Common Terminology Criteria for Adverse Events. In this mono-institutional retrospective study, age and radiotherapy dose were associated with a longer OS, while preoperative size and grading of the tumor influenced DFS. Although there were some advantages in terms of OS for patients treated with postoperative radiotherapy, the benefit did not reach the significance. Multicenter prospective studies are necessary to clarify the management and the correct timing of radiotherapy in such a rare disease.

    ABSTRACT: We report a case of a 30 years old male affected by synchronous bilateral germ cell tumor with a history of unilateral cryptorchidism; the patient underwent surgical treatment followed by adjuvant radiotherapy on paraaortic and iliac lymphnodes. Patients with synchronous tumors usually present with a higher stage disease in contrast to those with unilateral testicular carcinoma, yet the prognosis remains equally favorable. Key words: bilateral seminoma - cryptorchidism - radiotherapy - testicular cancer - germ cell tumor.

    ABSTRACT: Noninvasive cellular imaging allows the tracking of grafted cells as well as the monitoring of their migration, suggesting potential applications to track both cancer and therapeutic stem cells. Cell tracking can be performed by two approaches: direct labeling (cells are labeled with tags) and indirect labeling (cells are transfected with a reporter gene and visualized after administration of a reporter probe). Techniques for in vivo detection of grafted cells include optic imaging, nuclear medicine imaging, magnetic resonance imaging, microCT imaging and ultrasound imaging. The ideal imaging modality would bring together high sensitivity, high resolution and low toxicity. All of the available imaging methods are based on different principles, have different properties and different limitations, so several of them can be considered complementary. Transfer of these preclinical cellular imaging modalities to stem cells has already been reported, and transfer to clinical practice within the next years can be reasonably considered.

    ABSTRACT: Percutaneous fine-needle aspiration biopsy (FNAB) is a well-established and useful procedure in the diagnosis of lung squamous cell carcinoma (LSCC). Tumor seeding has been shown to be a potential risk. We report the case and management of a 78-year-old patient affected by LSCC who developed a chest wall metastasis in a straight line from the primary lesion along the FNAB needle track. Although tumor seeding after FNAB is a rare but possible complication, we suggest that careful examination for implantation (with periodical CT scans) should be performed for at least three years after FNAB.

    ABSTRACT: Aims and background. Concomitant radio-chemotherapy improves survival of patients with locally advanced non-small cell lung cancer, with a better local-regional control. Methods and study design. We report our experience with vinorelbine-based chemotherapy in neoadjuvant and radical settings in 43 patients. Regimens consisted of cisplatin plus vinorelbine in 74.4% patients and carboplatin plus vinorelbine in 14.0%; 11.6% underwent mono-chemotherapy with oral vinorelbine. We estimated the crude probability of death or local recurrence by the Kaplan-Meier method. Cox regression models were used to identify the main significant predictors of death or local recurrence. Results. A significant effect of the response to treatment was shown on both local disease free-survival (P = 0.004) and overall survival (P <0.0001). Patients with progressive disease after primary treatment had a significantly higher risk of further relapse at both univariate (P = 0.046) and multivariate regression analysis (P = 0.014) than patients with a complete response. They also showed a significantly higher risk of death at both univariate (P = 0.0005) and multivariate regression analysis (P <0.0001) than patients with a complete response. The most common toxicity was hematologic and gastroenteric. We recorded grade III/IV leukopenia in 11%, anemia in 6%, and esophagitis in 14% of the patients. Conclusions. Our experience showed that vinorelbine-based chemotherapy is an effective and safe regimen, in association with a platinum compound and thoracic radiotherapy.

    ABSTRACT: Inflammatory breast cancer represents a rare and extremely aggressive subtype of breast cancer. Due to its rarity, prospective studies are a difficult goal to obtain in this field. Nowadays a multimodal approach seems to be the standard approach. Role and timing of surgery, radiotherapy and chemotherapy are still debated issues. In this scenario interest is rising in molecular and target therapies. We performed a review analyzing the management of this unfavorable disease focusing on the role of radiotherapy, with particular emphasis on levels of evidence.

    ABSTRACT: Small cell lung cancer is characterized by an aggressive clinical course and a high sensitivity to both chemotherapy and radiotherapy. We present the Florence University experience in concurrent early radio-chemotherapy in patients affected by limited-stage small cell lung cancer, with particular emphasis on treatment safety, disease outcome and prognostic factors. Fifty-seven patients were treated between June 2000 and February 2005. All patients underwent platinum-based chemotherapy, administered intravenously following two different regimens, for at least three cycles. Eighteen patients (31.6%) received epirubicin and ifosfamide in 3-week cycles alternating with etoposide and cisplatin, administered on day 1 to 3; 39 patients (68.4%) received etoposide and cisplatin. A total of 6 cycles were planned. Radiotherapy was administered concurrently to the first cycle of etoposide and cisplatin. Clinical stage (P = 0.036) and number of chemotherapy courses (P = 0.009) emerged as the only significant death predictors at univariate analysis. Number of chemotherapy courses persisted as a significant death predictor also at multivariate regression analysis, with a reduced death risk for 5-6 chemotherapy cycles in comparison to 3-4 cycles (hazard ratio, 0.44). At a mean follow up of 38.5 months (standard deviation, 3.24 years; range, 6-164 months), considering the best overall tumor response achieved at any time during the whole treatment period, we obtained 32 complete responses (56.1%), 23 partial responses (40.3%) and 2 stable diseases. Our analysis showed that concurrent early radio-chemotherapy in limited-stage small cell lung cancer treatment represents a safe and effective approach in patients. We confirmed the relevant impact on overall survival of effective chemotherapy delivery.

    ABSTRACT: The objective of this study was to evaluate prognostic factors of local and distant recurrence in patients diagnosed with T1a and T1b, lymph node-negative breast carcinoma (BC) with emphasis on human epidermal growth factor receptor 2 (HER2) status. The authors reviewed 704 women with T1aT1bN0M0 BC who received treatment at the Radiation-Oncology Center of Florence University between November 2002 and December 2008. Patients with ductal carcinoma in situ or recurrent BC at presentation and patients who received adjuvant chemotherapy were excluded from the analysis. In total, 75 patients had HER2-positive BC (10.7%). At a mean follow-up of 4.9 years (standard deviation, 2.6 years; range, 0.5-10.8 years), 19 events were identified, including 10 distant recurrences. Patients with HER2-positive BC had worse distant recurrence-free survival (DRFS) than patients with HER2-negative BC (hazard ratio, 3.66; 95% confidence interval, 0.94-14.69; P = .045). Negative hormone receptor (HR) status was associated significantly with worse DRFS (hazard ratio, 0.26; 95% confidence interval, 0.07-0.93; P = .026). In multivariate analysis, younger age was the only significant risk factor for an event of recurrence (hazard ratio, 0.61;95% confidence interval, 0.20-1.82; P = .029). The current results indicated that patients with T1a/T1b, lymph node-negative BC have a low risk of distant and local recurrence, but younger age is a significant risk factor for events occurrence. Young women with HER2-positive and HR-negative status have a significant risk of distant recurrence and should be considered for future clinical trials with anti-HER2 adjuvant therapy.

    ABSTRACT: This study was done to evaluate the toxicity related to concurrent radiotherapy and anthracycline (AC)-based chemotherapy in the adjuvant treatment of early breast cancer and to investigate the impact of treatment interruptions and the feasibility of this uncommon therapeutic approach. From September 2002 to December 2007, 60 patients were treated at our Centre. The mean age at presentation was 48.5 (range 38-64) years. All patients underwent conservative surgery, and radiotherapy to the entire breast (mean dose 50 Gy; range 46-52 Gy). AC-based regimens consisted of four cycles of AC (doxorubicin plus cyclophosphamide) or four cycles of epirubicin (EPI) followed by four courses of cyclophosphamide, methotrexate and 5-fluorouracil (CMF). Concomitant treatment caused acute skin G3 toxicity in 8.9% of patients and one case of G4 toxicity (1.7%). Concerning cardiac assessment, six of the 56 evaluable patients (10.7%) developed an asymptomatic decline of left ventricular ejection fraction >10% and <20% of the baseline value. Radiotherapy was temporarily stopped in 21.3% and chemotherapy in 57.1% of patients. In our experience, concomitant chemotherapy did not emerge as a significant factor in radiotherapy interruption. Moreover, no severe cardiac events were recorded.

    ABSTRACT: Radiotherapy (RT) plays an important role in the management of locally advanced breast cancer (BC). Postmastectomy RT has been shown to significantly reduce the risk of loco-regional failure and to improve disease free survival in high-risk women with BC. Many trials have shown a significant benefit in local control, disease-free and overall survival with the addition of RT for patients with stage II and III breast cancer. New perspectives are evaluating multiple biological variables that nowadays should be considered in clinical oncology for the prescription of postmastectomy radiation therapy. Tailored randomized trials are now ongoing to clarify the "grey zone" represented by the intermediate-risk group of patients (1-3 lymph nodes involved). We reviewed the major studies offered by literature with emphasis on the principal debated issues.

    ABSTRACT: Post-operative radiotherapy (PORT) in radically resected non-small cell lung cancer (NSCLC) has the aim to reduce loco regional recurrence and to improve overall survival. PORT has been evaluated in several trials but indication to post-operative treatment in N2 patients is still debated. We retrospectively analyzed 175 patients treated at University of Florence between 1988 and 2004 with completely resected NSCLC stages IIIA-IIIB, N2 disease. Surgery consisted in a lobectomy in 58.9% and in a bi-lobectomy or in a pneumonectomy in 41.1% of patients. One hundred and nineteen patients underwent PORT and 56 patients did not receive PORT (no-PORT). At a median follow-up of 27.6 months (range 4-233 months), we found a significant reduction in local recurrence (LR) in PORT group (log-rank test p=0.015; HR: 0.45; 95%CI: 0.24-0.87). No statistical difference were found in terms of overall survival (OS) (log-rank test p=0.92). Concerning other prognostic factors, male sex emerged as statistically significant (HR:4.33;1.04-18.02) on local progression free survival (LPFS) at univariate analysis. Acute and long-term toxicity was mild. Our retrospective analysis showed that PORT may improve local disease control in N2 NSCLC patients with an acceptable treatment-related toxicity.

    ABSTRACT: AIMS: We conducted a retrospective analysis in order to evaluate the impact of age on women aged less than 35 years affected by breast cancer. MATERIALS AND METHODS: Between January 1972 and December 2006, 346 patients aged less than 35 years underwent adjuvant treatment at Florence University. The mean age of the patient population was 32 years (range 22-35): 76 patients were under 30 years old, the remaining were above 30 years old. RESULTS: In our series, 215 patients received adjuvant radiotherapy to whole breast after conservative surgery, 131 patients underwent mastectomy without subsequent radiation therapy and 323 patients had lymphadenectomy; 191 patients received adjuvant chemotherapy, 73 with anthracycline-containing regimen. With a median time of 2.5 years (range 6 months to 27.6 years) local relapses were observed in 67 cases (19.4%). At the multivariate analysis of local disease-free survival, ductal and ductal plus lobular histotypes, having more than 3 positive nodes, and age emerged as independent significant relapse predictors (p=0.018, p=0.0005, p=0.003 and p=0.024, respectively). For the DSS analysis, the median follow-up was 6.8 years (range 0.6-36.7 years). At the multivariate analysis, age (p=0.0038), positive nodes (p=0.0035) and distant metastases (p<0.0001) resulted to be independent death predictors. Patients younger than 30 had a worse prognosis. At the univariate analysis also local relapse resulted to be statistically significant (p=0.0004). CONCLUSIONS: Anthracycline-based chemotherapy seems to improve the outcome of these patients. However, there is an urgent need for tailored treatment investigations within the framework of randomized, controlled clinical trials.

    ABSTRACT: Aims and background. To report the clinical outcome of linac-based or robotic, image-guided stereotactic body radiotherapy in patients affected by abdominal lymph node metastases from different primary cancers. Methods and methods. Twenty-six patients with 32 abdominal lymph node metastases were consecutively treated at the University of Florence between April 2011 and May 2012. The mean follow-up was 4.6 months (SD, 3.9; range, 0.3-13). The dose prescription ranged between 24 Gy and 36 Gy delivered in 1-5 fractions. Results. In terms of local control, complete response to stereotactic body radiotherapy was obtained in 18 cases (66.7%), partial response in 7 (25.9%), and stable disease in 2 (7.4%). At the Cox univariate regression analysis, an increased risk of partial response or absence of local response to radiotherapy was found for subjects of the female sex (P = 0.036), age less than 50 years (P = 0.022), primary tumor of the genital tract (P = 0.007), and previous chemotherapy (P = 0.057). An excellent local control rate (90.9%) was obtained in patients affected by abdominal lymph node metastases of prostatic origin. Conclusions. Stereotactic body radiotherapy for abdominal lymph node metastases is a safe and effective treatment in terms of high rates of local control, especially in a subset of patients affected by prostate cancer.

    ABSTRACT: We report the case of a 48-year-old woman affected by inoperable primary angiosarcoma of the right atrium who was treated with 4 cycles of induction chemotherapy and radical radiotherapy. We present the application and the result of helical tomotherapy for this patient. We also describe the technical aspects of the simulation, planning, setup and delivery of radiotherapy. At 16 months after the diagnosis the patient is still in good condition without any symptoms and with a partial response of the lesion. This case shows the feasibility of treatment with high doses of radiation for a primary unresectable cardiac sarcoma.
