RESUMO

BACKGROUND: Basophils, eosinophils and monocytes may be involved in BCG-induced immune responses and be associated with outcomes of bladder cancer patients receiving intravesical BCG. Our objective was to explore the association of baseline counts of basophils, eosinophils and monocytes with outcomes of patients with high-grade T1 bladder cancer receiving a standard course of intravesical BCG. METHODS: We retrospectively reviewed medical records of patients with primary T1 HG/G3 bladder cancer. After re-TURBT, patients were treated with a 6-week course of intravesical BCG induction followed by intravesical BCG every week for 3 weeks given at 3, 6, 12, 18, 24, 30 and 36 months from initiation of therapy The analysis of potential risk factors for recurrence, muscle invasion and cancer-specific and overall survival was performed using univariable Cox regression models. Those factors that presented, at univariate analysis, an association with the event at a liberal p < 0.1, have been selected for the development of a multivariable model. RESULTS: A total of 1045 patients with primary T1 HG/G3 were included. A total of 678 (64.9%) recurrences, 303 (29.0%) progressions and 150 (14.3%) deaths were observed during follow-up. Multivariate analysis showed that logarithmic transformation of basophils count was associated with a 30% increment in the hazard of recurrence per unit increase of logarithmic basophils count (HR 1.30; 95% confidence interval 1.09-1.54; p = 0.0026). Basophil count modeled by quartiles was also significantly associated with time to recurrence [second vs. lower quartile HR 1.42 (1.12-1.79); p = 0.003, third vs. lower quartile HR 1.26 (1.01-1.57); p = 0.041; upper vs. lower quartile HR 1.36 (1.1-1.68); p = 0.005]. The limitations of a retrospective study are applicable. CONCLUSION: Baseline basophil count may predict recurrence in BCG-treated HG/G3 T1 bladder cancer patients. External validation is warranted.

RESUMO

BACKGROUND: Primary tumor characteristics, which are readily available to all clinicians, may aid in selecting the optimal adjuvant therapy for patients with breast cancer (BC). Herein, we investigated the relationship between tumor size, hormone receptor and HER2 status, Ki67 and age with axillary lymph node metastases (ALNM) in early-BC patients. METHODS: We analyzed data on consecutive 2600 early-BC cases collected in the registry of Fondazione IRCC Istituto Nazionale dei Tumori, Milano, Italy. Correlation between Ki67 and primary tumor size (T-size) was calculated by Spearman's rank correlation coefficient. Association of ALNM with Ki67 and other tumor characteristics was investigated by logistic regression. Adjusted odds ratios (ORs) with 95% confidence intervals (95% CIs) were estimated in all cases, and separately analyzed according to age, T-size and BC subtype. RESULTS: Large tumor size strongly associated to ALNM, with an adjusted odds ratio (OR) for each 5-mm increase of 1.32 (95% CI 1.24-1.41), except for triple-negative BC (TNBC) cases. In tumors =10 mm, without lymphovascular invasion, representing the strongest predictor of ALNM (OR 6.09, 95% CI 4.93-7.53), Ki67 resulted particularly informative, with a fourfold increased odds of ALNM for values > 30%. CONCLUSIONS: These results raise the question whether axillary node status is redundant in cases with exceptionally good features, i.e., small tumors with low Ki67, or in those candidate to adjuvant systemic treatment/radiotherapy anyway including TNBC, and support the incorporation of primary BC tumor characteristics as stratification factors in ongoing trials aiming at de-escalating axillary surgical procedures.

RESUMO

Primary extranodal marginal zone B-cell lymphomas (MALToma) of the endometrium are rare tumors. We report a case of MALToma diagnosed within an endometrial polyp in a patient presenting with postmenopausal vaginal bleeding. The patient underwent a conventional hysteroscopic procedure for intrauterine polyps. There was no suspicion of malignancy during the preoperative investigations or at surgery. Conventional bipolar resection of the polyps was performed. The present case demonstrates that conservative management of endometrial MALToma may be considered as a safe alternative to hysterectomy. Further data on long-term follow up is needed to confirm the safety of this conservative approach.

RESUMO

Epigenetic changes are defined as inherited modifications that are not present in DNA sequence. Gene expression is regulated at various levels and not only in response to DNA modifications. Examples of epigenetic control are DNA methylation, histone deacetylation and mi-RNA expression. Methylation of several tumor suppressor gene promoters is responsible for their silencing and thus potentially sustain cancerogenesis. Similarly, histone deacetylation can lead to oncogene activation. mi-RNA are small (18-20 nucleotides) non-coding RNA fragments capable of inhibiting other m-RNA, ultimately altering the balance in oncogene and tumor suppressor gene expression. It has been shown that growth of several tumor types can be stimulated by epigenetic changes in various phases of cancerogenesis, and drugs able to interfere with these mechanisms can have a positive impact on tumor progression. As matter of fact, epigenetic changes are dynamic and can be reversed by epigenetic inhibitors. Recently, methyltransferase and histone deacetylase inhibitors have attracted the attention of researchers and clinicians as they potentially provide alternative therapeutic options in some cancers. Drugs that inhibit DNA methylation or histone deacetylation have been studied for the reactivation of tumor suppressor genes and repression of cancer cell growth. Epigenetic inhibitors work alone or in combination with other therapeutic agents. To date, a number of epigenetic inhibitors have been approved for cancer treatment. The main challenge in the field of epigenetic inhibitors is their lack of specificity. In this review article we describe their mechanisms of action and potential in cancer treatment.

RESUMO

BACKGROUND: Trials of salvage therapy for advanced urothelial carcinoma have required prior platinum-based therapy. This practice requires scrutiny because non-platinum-based first-line therapy may be offered to cisplatin-ineligible patients. PATIENTS AND METHODS: Data of patients receiving salvage systemic chemotherapy were collected. Data on prior first-line platinum exposure were required in addition to treatment-free interval, hemoglobin, Eastern Cooperative Oncology Group performance status, albumin, and liver metastasis status. Cox proportional hazard regression was used to evaluate their association with overall survival (OS) after accounting for salvage single-agent or combination chemotherapy. RESULTS: Data were obtained from 455 patients previously exposed to platinum-based therapy and 37 not exposed to platinum. In the group exposed to prior platinum therapy, salvage therapy consisted of a single-agent taxane (n = 184) or a taxane-containing combination chemotherapy (n = 271). In the group not exposed to prior platinum therapy, salvage therapy consisted of taxane or vinflunine (n = 20), 5-fluorouracil (n = 1), taxane-containing combination chemotherapy (n = 12), carboplatin-based combinations (n = 2), and cisplatin-based combinations (n = 2). The median OS for the prior platinum therapy group was 7.8 months (95% confidence interval, 7.0, 8.1), and for the group that had not received prior platinum therapy was 9.0 months (95% confidence interval, 6.0, 11.0; P = .50). In the multivariable analysis, prior platinum therapy versus no prior platinum exposure did not confer an independent impact on OS (hazard ratio, 1.10; 95% confidence interval, 0.75, 1.64; P = .62). CONCLUSION: Prior platinum- versus non-platinum-based chemotherapy did not have a prognostic impact on OS after accounting for major prognostic factors in patients receiving salvage systemic chemotherapy for advanced urothelial carcinoma. Lack of prior platinum therapy should not disqualify patients from inclusion onto trials of salvage therapy.

RESUMO

BACKGROUND: First-line sunitinib is recommended in metastatic renal cell carcinoma (mRCC), but it is frequently associated with relevant toxicities and subsequent dose reductions. Alternative schedules, such as 2-week-on treatment and 1-week-off (2/1 schedule), might improve tolerability. We evaluated the safety and outcomes of this schedule in a large multicenter analysis. PATIENTS AND METHODS: Retrospective, multicenter analysis of mRCC patients treated with first-line sunitinib on a 2/1 schedule. Data of 249 patients were reviewed: 208 cases who started sunitinib on the 4/2 schedule (full dosage: 188/208, 90.4%) and thereafter switched to the 2/1 schedule for toxicity (group 4/2 → 2/1) and 41 patients who started first-line sunitinib with the 2/1 schedule because of suboptimal clinical conditions (group 2/1). A total of 211 consecutive patients treated with the 4/2 schedule in another institution served as external controls. Safety was the primary end point. Treatment duration (TD), progression-free survival (PFS) and overall survival (OS) were also analyzed. RESULTS: In group 4/2 → 2/1, the overall incidence of grade ≥ 3 toxicities was significantly reduced (from 45.7% to 8.2%, P < 0.001) after the switch to 2/1 schedule. This advantage was maintained also in the 106/188 cases (56.4%) who maintained the full dosage. Fatigue, hypertension, hand-foot syndrome and thrombocytopenia were less frequent. The incidence of grade ≥ 3 adverse events in the negatively selected group 2/1 (only 73.2% starting at full dose) was 26.8%, similar to what observed in the external control group (29.4%). Median TD was 28.2 months in the 4/2 → 2/1 group (total time spent with both schedules), 7.8 months in the 2/1 group and 9.7 months in external controls. Median PFS was 30.2, 10.4 and 9.7 months, respectively. Median OS was not reached, 23.2 and 27.8 months, respectively. CONCLUSIONS: mRCC patients who moved to a modified 2/1 schedule of sunitinib experience an improved safety profile compared with that observed during the initial 4/2 schedule.

RESUMO

Renal cell carcinoma is an aggressive disease often asymptomatic and weakly chemo-radiosensitive. Currently, new biologic drugs are used among which everolimus, an mTOR inhibitor, that has been approved for second-line therapy. Since mTOR is involved in the control of autophagy, its antitumor capacity is often limited. In this view, chloroquine, a 4-alkylamino substituted quinoline family member, is an autophagy inhibitor that blocks the fusion of autophagosomes and lysosomes. In the present study, we evaluated the effects of everolimus alone or in combination with chloroquine on renal cancer cell viability and verified possible synergism. Our results demonstrate that renal cancer cells are differently sensitive to everolimus and chloroquine and the pharmacological combination everolimus/chloroquine was strongly synergistic inducing cell viability inhibition. In details, the pharmacological synergism occurs when chloroquine is administered before everolimus. In addition, we found a flow autophagic block and shift of death mechanisms to apoptosis. This event was associated with decrease of Beclin-1/Bcl(-)2 complex and parallel reduction of anti-apoptotic protein Bcl(-)2 in combined treatment. At last, we found that the enhancement of apoptosis induced by drug combination occurs through the intrinsic mitochondrial apoptotic pathway activation, while the extrinsic pathway is involved only partly following its activation by chloroquine. These results provide the basis for new therapeutic strategies for the treatment of renal cell carcinoma after appropriate clinical trial.

RESUMO

BACKGROUND: The differential impact of the number of prior lines of therapy and the setting of prior therapy (perioperative or metastatic) is unclear in advanced urothelial carcinoma. PATIENTS AND METHODS: Ten phase II trials of salvage chemotherapy, biologic agent therapy, or both, enrolling 731 patients, were available. Data on the number of prior lines of therapy and the setting of prior therapy were required in addition to known previously recognized prognostic factors: time from prior chemotherapy, hemoglobin level, performance status, and liver metastasis status. Cox proportional hazards regression was used to evaluate the association of the number of prior lines and prior perioperative therapy with overall survival (OS) as the primary clinical endpoint. Trial was a stratification factor. RESULTS: A total of 711 patients were evaluable. The overall median progression-free survival and OS were 2.7 and 6.8 months, respectively. The number of prior lines was 1 in 559 patients (78.6%), 2 in 111 (15.6%), 3 in 29 (4.1%), 4 in 10 (1.4%), and 5 in 2 (0.3%). Prior perioperative chemotherapy was given to 277 (39.1%) and chemotherapy for metastatic disease to 454 (64.1%). The number of prior lines was not independently associated with OS (hazard ratio, 0.99; 95% CI, 0.86-1.14). Prior perioperative chemotherapy was a favorable factor for OS on univariate but not multivariate analysis. CONCLUSION: The number of prior lines of therapy and prior perioperative chemotherapy were not independently prognostic in patients with urothelial carcinoma receiving salvage therapy. Adoption of these data in salvage therapy trials should enhance accrual, the interpretability of results, and drug development.

RESUMO

BACKGROUND: Cervical pregnancy (CP) is a life-threatening condition that represents less than one percent of all ectopic pregnancies. Transvaginal sonography (TVS) is the gold standard for an accurate diagnosis. For hemodinamically stable women the available treatments involve a medical therapy, alone or in combination with interventional measures (hysteroscopy, angiographic embolization or laparoscopic ligation of uterine arteries). MATERIALS AND METHODS: The authors describe a CP unsuccessfully treated with methotrexate (MTX), but resolved with hysteroscopy. CASE REPORT: A nulliparous woman arrived with low abdominal pain without vaginal bleeding at six weeks of amenorrhea. TVS revealed a gestational sac implanted in the isthmic cervical region, with a serum beta-hCG of 1,100 mUI/ml, that raised to 4,274 mUI/ml in a week, despite one intrasaccular-MTX injections and two systemic doses. The authors arranged for a hysteroscopic resection with no previous dilatation of the cervix. They did not adopt any safety precautions to their procedure. CONCLUSION: It is difficult to define the exact role of hysteroscopy regarding CP. Despite some authors dispute on its complementary function to MTX, the authors believe that it could be used as a rescue method in case of MTX failure. The final aims of a proper management are to minimize the risk of haemorrhage and preserve women's fertility.

RESUMO

The therapeutic landscape of metastatic castration-resistant prostate cancer (mCRPC) has been revolutionized by the arrival of multiple novel agents in the past 2 years. Immunotherapy in the form of sipuleucel-T, androgen axis inhibitors, including abiraterone acetate and enzalutamide, a chemotherapeutic agent, cabazitaxel, and a radiopharmaceutical, radium-223, have all yielded incremental extensions of survival and have been recently approved. A number of other agents appear promising in early studies, suggesting that the armamentarium against castrate-resistant prostate cancer is likely to continue to expand. Emerging androgen pathway inhibitors include androgen synthesis inhibitors (TAK700), androgen receptor inhibitors (ARN-509, ODM-201), AR DNA binding domain inhibitors (EPI-001), selective AR downregulators or SARDs (AZD-3514), and agents that inhibit both androgen synthesis and receptor binding (TOK-001/galeterone). Promising immunotherapeutic agents include poxvirus vaccines and CTLA-4 inhibitor (ipilimumab). Biologic agents targeting the molecular drivers of disease are also being investigated as single agents, including cabozantinib (Met and VEGFR2 inhibitor) and tasquinimod (angiogenesis and immune modulatory agent). Despite the disappointing results seen from studies evaluating docetaxel in combination with other agents, including GVAX, anti-angiogentic agents (bevacizumab, aflibercept, lenalinomide), a SRC kinase inhibitor (dasatinib), endothelin receptor antagonists (atrasentan, zibotentan), and high-dose calcitriol (DN-101), the results from the trial evaluating docetaxel in combination with the clusterin antagonist, custirsen, are eagerly awaited. New therapeutic hurdles consist of discovering new targets, understanding resistance mechanisms, the optimal sequencing and combinations of available agents, as well as biomarkers predictive for benefit. Novel agents targeting bone metastases are being developed following the success of zoledronic acid and denosumab. Finally, all of these modalities do not appear curative, suggesting that clinical trial enrollment and a better understanding of biology remain of paramount importance.

RESUMO

Background Penile cancer (PC) is a rare cancer in western countries, but is more common in parts of the developing world. Due to its rarity and the consequent lack of randomized trials, current therapy is based on retrospective studies and small prospective trials. Design Studies of PC therapy were searched in PubMed and abstracts at major conferences. Results PC is generally an aggressive malignancy characterized by early locoregional lymph node (LN) spread and later metastases in distant sites. Given the strong predictive value of LN involvement for overall survival, evaluating regional LNs is critical. Advanced LN involvement is increasingly being treated with multimodality therapy incorporating chemotherapy and/or radiation. A single superior cisplatin-based regimen has not been defined. Further advances may occur with a better collaboration on an international scale and comprehensive understanding of tumor biology. To this end, the preventive role of circumcision and understanding of the oncogenic roles of Human Papilloma Virus-16, and smoking may yield advances. Preliminary data suggest a role for agents targeting epidermal growth factor receptor and angiogenesis. Conclusion Advances in therapy for PC will require efficient trial designs, synergistic collaboration, incentives to industry and the efforts of patient advocacy groups and venture philanthropists.

RESUMO

BACKGROUND: Almost 30% of the sunitinib-treated patients for metastatic renal carcinoma (mRCC) do not receive a clinical benefit. Convincing evidences demonstrated a cross talk between the VEGF and CXCR4 pathways. It was hypothesized that CXCR4 expression in primary renal cancer could predict sunitinib responsiveness. PATIENTS AND METHODS: In this exploratory study sixty-two mRCC patients receiving sunitinib as first-line treatment were evaluated for CXCR4 expression through immunohistochemistry (IHC). Correlations between CXCR4 expression, baseline patients and tumour characteristics were studied by contingency tables and the chi-square test. Univariable analysis was performed with the log-rank test, and the Cox model was applied for multivariable analysis. RESULTS: The objective response rate of sunitinib first-line therapy was 35.5% (22/62) with a disease control rate (response and stable disease) of 62.9% (39/62). CXCR4 expression was absent/low in 30 (48.4%), moderate in 17 (27.4%), and high in 15 (24.2%) tumors respectively. Low or absent CXCR4 expression predicted response to sunitinib therapy. Moreover, Fuhrman grading and concomitant, CXCR4 and Fuhrman grading, strongly predicted sunitinib first line therapy responsiveness on progression-free survival and overall survival. CONCLUSIONS: High CXCR4 expression correlates with sunitinib poor response in metastatic renal cancer.

RESUMO

OBJECTIVE: To evaluate the detection of pregnancy hypertensive disorders by integrating maternal history, serum biomarkers and uterine artery Doppler in the first trimester. METHODS: We prospectively recruited 2118 women that underwent an 11-13 weeks aneuploidy screening. We gathered information on maternal history, uterine artery Doppler and serum biomarkers (PAPP-A, PlGF, PP-13 and free ß-hCG). Models were developed for the prediction of overall preeclampsia (PE), early-onset PE, late-onset PE and gestational hypertension (GH). For each outcome, we performed a multivariate logistic regression starting from the saturated model: adopting a step-down procedure we excluded all factors not statistically significant (p > 0.05). Sensitivity models only for statistically significant parameters were calculated from the ROC curves for fixed false-positive rates (FPR). RESULTS: Among 2118 women, 46 (2.17%) developed GH and 25 (1.18%) were diagnosed with PE, including 12 (0.57%) early-onset PE and 13 (0.61%) late-onset PE. For a fixed FPR of 10 and 5%, serum PlGF, free ß-hCG and chronic hypertension identified respectively 67 and 75% of women who developed early-onset PE. In the model for the prediction of overall PE the combination of the uterine artery Doppler pulsatility index (UtA PI) with PlGF and chronic hypertension reached a sensitivity of 60% for a 20% of FPR. CONCLUSION: An integration of maternal characteristics and first trimester maternal serum biomarkers (free ß-hCG and PlGF) provided a possible screening for early-onset PE. In the overall PE model, UtA PI turned out to be statistically significant but did not improve the detection rate.

RESUMO

Neuroendocrine tumors (NETs) are rare, with an incidence of about 5 per 100,000 inhabitants. As no study on NETs has ever been specifically conducted on the population of Campania, we performed a retrospective analysis of all newly diagnosed NETs at the Antonio Cardarelli hospital between 2006-2009. A search of the registry of the Pathology Department of the Antonio Cardarelli hospital was carried out to retrieve available data on all newly diagnosed NET cases. Two hundred and ninety-nine NET tumors were diagnosed at our Institution from January, 2006 to December, 2009. Globally, 121 patients (40% of the population) had a lung NET, while 92 patients (30% of the population) presented a GEP-NET. The most common primary tumor site varied by sex, with female patients being more likely to have a primary NET in the lung, breast or colon, and male patients being more likely to have a primary tumor in the lung. Also, twenty-three cases of breast NETs were identified, and clinical information regarding therapy and response was available for 22 patients. Our study represents a pioneering effort to provide the medical community in Campania with basic information on a large number of patients with different types of NETs. The Antonio Cardarelli hospital could greatly benefit from cooperation with other hospitals in order to become a highly specialized center for NETs in the region and Southern Italy.

RESUMO

PURPOSE: Over the last few years, targeted agents have assumed a predominant role in treatment of metastatic renal cell carcinoma (mRCC). Our aim is to discuss recent developments on this rapidly evolving topic. EVIDENCE SYNTHESIS: Sunitinib represents front-line standard treatment for the good- and intermediate prognosis groups of patients with clear cell renal carcinoma. Bevacizumab/interferon and pazopanib have also been FDA-approved as first-line agents, while sorafenib has moved toward second-line and later therapy. Temsirolimus, an mTOR inhibitor, is recommended as front line therapy for patients in the poor-risk group and is the best front-line choice for patients with non-clear cell histology. Another mTOR inhibitor, everolimus, has shown clinical benefit post-tyrosine kinasis inhibitors failure in a phase III study and is considered the standard of care in this setting. Novel prognostic and efficacy markers might help to define most appropriate therapeutic strategy. Best sequence of use of these effective agents in mRCC patients remains up to the discretion of treating physician. CONCLUSIONS: In light of the considerable advances in understanding the biology of mRCC, several new drugs have been recently developed, with an increasing number of treatment options. Several markers are under evaluation for diagnostic, prognostic and efficacy purposes. A treatment algorithm, based on the best scientific evidence produce so far, is presented and it will evolve as data from ongoing trials will be available.

RESUMO

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death worldwide. No effective systemic treatment has been established, except for sorafenib chemotherapy. In fact, sorafenib has proved to provide a statistically significant survival extension of about two months in two phase III trials in the North America-Europe area and in the Asia-Pacific area, which respectively reported a median survival after treatment of 10.7 and 6.5 months, respectively. We report the case of an HCC patient, who received a four-month therapy with sorafenib with a clinical, biochemical and radiographic response, but had to interrupt treatment because of a myocardial infarction. Surprisingly, despite no antitumor treatment having been administered for about a year, the patient has shown no tumor progression and is currently on a close follow-up. Should other similar cases be presented, a subset of patients with long-lasting response to sorafenib might be identified.

RESUMO

Anthracycline-containing chemotherapy (A-CHT) can induce late cardiotoxicity adding a considerable burden to cardiovascular risk. Irradiation of left breast cancer has also been associated to an increased risk of cardiovascular disease. The aim of this observational study is to prove the usefulness of an accurate cardiovascular evaluation in left breast cancer survivors treated with radiotherapy (RT) and A-CHT. Patients with left breast cancer, on follow-up after treatment with A-CHT plus RT in an adjuvant setting, were eligible for this observational study. Patients underwent cardiovascular assessment with myocardial perfusion imaging. Thirty patients were enrolled in the study: mean age at diagnosis 55.8 years; stage: I/III; Er and/or pgR status: positive in 24/30 pts; 3 patients in pre-menopausal status. Twenty-two patients (73.3 percent) had normal perfusion imaging, 1 patient (3.3 percent) had a fixed myocardial perfusion defect, 7 patients (23.3 percent) had reversible myocardial perfusion defects; 1 patient (3 percent) with normal perfusion scan showed depressed rest and stress LVEF. Only 1 patient had a large defect and underwent coronary angiography and percutaneous coronary intervention. Five patients with small defect showed normal coronary arteries at Multislice Computed Tomography. Cardiovascular followup may reveal signs of A-CHT or RT-induced cardiotoxicity. A stress test combined with MPI- and GATED-derived data of ventricular systolic performance after stress can give information on the coronary reserve and the contractile reserve and allow early appropriate treatment.
