Incidence and Survival of Testicular Cancers in a Province in Northern Italy and Their Association with Second Tumors.

This study investigated the incidence, mortality, and 5-year survival rates of testicular cancers diagnosed in a northern Italian province, which were eventually associated with previous or subsequent extratesticular neoplasms. Cases from 1996 to 2020 were examined by age and histotype (seminoma vs. non-seminoma). The standardized incidence rate was calculated using the European population, and the annual percent change (APC) was reported. The five-year relative survival was estimated using the Pohar Perme method. The association with the second neoplasm was also evaluated. In our study, 385 patients with testicular cancer were included, most of whom were aged between 30 and 40 years. The non-seminoma and seminoma groups accounted for 44% and 18% of younger adults, respectively. The incidence rate increased during the study period (APC 1.6*); however, it increased in seminomas (APC 2.3*) but not in non-seminomas (APC -0.1). Conversely, the mortality rate remained constantly low either overall or in each of the two groups. The overall 5-year survival rate of testicular cancer patients was 95% (99% and 88% for seminomas and non-seminomas, respectively). Primary extratesticular tumors were documented in 37 cases, 18 after and 19 before the testicular cancer diagnosis. Our study confirms that the increased incidence and excellent survival rate are the prerogative of seminomas.

[Hormone therapy, cardio-metabolic profile, and cardiotoxicity. Still a dark side of cardio-oncology - Part 2: Prostate cancer]. / Terapia ormonale, assetto cardio-metabolico e cardiotossicità. Il lato ancora oscuro della cardioncologia ­ Parte 2: Tumore della prostata.

Hormone therapies (HTs) with anti-androgenic properties are a cornerstone for the treatment of prostate cancer (PC) and have significantly improved the survival of patients, though exposing them to a higher risk of cardiovascular diseases (CVDs), which represent a major cause of morbidity and mortality. This occurs due to the high average age of patients undergoing HT for PC, an age group in which CVDs have a high prevalence and incidence, and due to the type and duration of HTs that are increasingly effective but at the same time more aggressive towards cardiovascular health. Recent evidence from the real world suggests, however, that the cardiometabolic risk is widely underestimated and undertreated with significant impact also on the oncological prognosis. In the light of the results of the PRONOUNCE study, in this review it is emphasized the need for a multidisciplinary management of patients with PC who are candidate for or treated with HT by implementing a personalized treatment program in accordance with the current European guidelines on CVD prevention.

Trends in Incidence and Mortality of Kidney Cancer in a Northern Italian Province: An Update to 2020.

The aim of this study was to examine the incidence and mortality trends for tumors and cardiovascular disease (CVD) in a province of northern Italy. The study included kidney cancers recorded in the period 1996−2020, divided by sex, age, year of incidence and years from diagnosis. The standardized incidence rate was calculated using the European population, and the Annual Percent Change (APC) was reported. In total, 2331 patients with kidney cancers were identified, mainly males (1504 cases) aged 60−79 years (1240 cases). There were 1257 deaths; there were no differences according sex but there were differences according to age (12.1% among younger adults and 80.4% among 80+). The incidence rate increased in males between 1996 and 2011 (APC = 2.3), while the mortality rate decreased in both males (APC = −3.3%) and females (APC = −4.5%). Comparing the same periods, kidney cancer-specific mortality decreased from 81.8% to 43.7%, while in the same period there was an increasing trend for CVD mortality. Moreover, the risk of CVD mortality increased as we moved away from the diagnosis (from 6.2% to 27.5%, p < 0.01). The same trend was observed for other causes of death (from 12.6% to 32.1%, p < 0.01). Thus, a multidisciplinary approach seems necessary during the follow-up and treatments of patients with kidney cancer.

Correlation Between Immune-related Adverse Event (IRAE) Occurrence and Clinical Outcome in Patients With Metastatic Renal Cell Carcinoma (mRCC) Treated With Nivolumab: IRAENE Trial, an Italian Multi-institutional Retrospective Study.

BACKGROUND: Immunotherapy has brought clinical benefits to patients with metastatic renal cell cancer (mRCC). Most patients tolerate immunotherapy but serious immune-related adverse events (irAEs) have been reported. Some studies indicate a correlation between irAEs and clinical response in other cancer types (eg, lung cancer and melanoma). For patients with mRCC, the impact of irAE on clinical outcome is unknown. PATIENTS AND METHODS: A retrospective review of 167 patients with mRCC treated with nivolumab as standard of care between March 2017 and January 2018 in 16 Italian centers was performed. irAEs were assessed using Common Terminology Criteria for Adverse Events (CTCAE) v.4.0. RESULTS: Any grade and grade 3/4 irAEs occurred in 46% and 8.9% of patients, respectively. The median time to appearance of irAEs was 10 weeks; 38.8% of patients required steroid treatment. The most common irAEs were cutaneous (33.7%) and gastrointestinal (23.3%). The median overall survival and progression-free survival were 20.13 and 7.86 months, respectively. Patients with irAEs showed a greater overall survival (hazard ratio, 0.38; 95% confidence interval [CI], 0.23-0.63) and progression-free survival (hazard ratio, 0.44; 95% CI, 0.29-0.66) benefit as well as better overall response rate (27.3% vs. 13.7%; odds ratio, 2.36; 95% CI, 1.03-5.44) and disease control rate (68.8% vs. 48%; odds ratio, 2.4; 95% CI, 1.23-4.67) if compared with those without irAEs. No correlation was found between steroid use and clinical outcomes. CONCLUSIONS: Our analysis revealed that the appearance of irAEs was associated with better outcomes in patients treated with nivolumab. This data may be limited by sample size and the retrospective nature of the study.

Fulminant hepatitis in a patient with hepatocellular carcinoma related to nonalcoholic steatohepatitis treated with sorafenib.

We describe a case of acute liver failure in a patient with advanced hepatocellular carcinoma related to nonalcoholic steatohepatitis during sorafenib treatment. A 74-year-old man with diabetes mellitus and hypertension was diagnosed with hepatocellular carcinoma associated with fatty liver. Three weeks after sorafenib therapy, at Eastern Cooperative Oncology Group performance status 3, he developed jaundice, general weakness, flapping tremor, nausea, and anorexia. Sorafenib was stopped: laboratory tests showed a relevant elevation of transaminases suggesting diagnosis of acute hepatitis. During hospital admission, the patient died of liver failure. Sorafenib is the first successful target therapy effective for advanced hepatocellular carcinoma. The most common adverse events are fatigue, hand-foot skin reaction, skin rash/desquamation, diarrhea, and hypertension, whereas liver dysfunction is uncommon. To our knowledge, this is the first patient reported in the literature with hepatocellular carcinoma related to nonalcoholic steatohepatitis who died of rapid worsening of liver function during sorafenib treatment.

Antiprotease strategy in pancreatic cancer treatment: emergence from a preclinical study.

OBJECTIVES: Resistance to gemcitabine is one of the main causes of treatment failure in pancreatic cancer. Compelling evidences have shown the involvement of nuclear factor κB (NF-κB) activation in such phenomenon. The protease inhibitor gabexate mesilate has been shown to inhibit NF-κB. We here investigated if combined treatment with this drug could improve gemcitabine antitumoral efficacy in pancreatic cancer cells. METHODS: The effect of gabexate mesilate and gemcitabine, both used at concentrations achievable in human plasma, was assessed on in vitro pancreatic cancer cell growth, invasion, and tumor angiogenesis. The molecular mechanism at the basis of these effects was also investigated. RESULTS: Gabexate mesilate significantly increased gemcitabine anti-invasive and antiangiogenic efficacy. This effect was related to inhibition of gemcitabine-induced NF-κB activation by gabexate mesilate, which prevented RelA/p65 nuclear translocation and resulted in metalloproteinase 2, metalloproteinase 9, vascular endothelial growth factor, and interleukin 8 down-regulation. Combined treatment with gabexate mesilate also inhibited gemcitabine-induced extracellular-regulated kinase 1/2 and AKT activation by increased expression of Raf kinase inhibitor protein and phosphatase and tensin homolog. CONCLUSIONS: Combined treatment with gabexate mesilate sensitizes pancreatic cancer cells to gemcitabine by inhibition of the NF-κB pathway. The efficacy of this therapeutic strategy in pancreatic cancer patients remains to be established and deserves future clinical investigation.

Metronomic capecitabine in advanced hepatocellular carcinoma patients: a phase II study.

UNLABELLED: Anti-angiogenic treatment with targeted agents is effective in advanced hepatocellular carcinoma (HCC). This trial evaluated the safety and efficacy of metronomic capecitabine in patients with HCC. METHODS: This single-institution phase II trial included 59 previously untreated patients with advanced HCC and 31 patients resistant to or intolerant of sorafenib. The treatment schedule was capecitabine 500 mg twice daily until progression of disease, unacceptable toxicity level, or withdrawal of informed consent. Progression-free survival (PFS) was chosen as the primary endpoint. RESULTS: A total of 59 previously untreated and 31 previously treated patients with HCC were enrolled. The first cohort achieved a median PFS of 6.03 months and an overall survival (OS) of 14.47 months. Two patients achieved a complete response, 1 patient achieved partial response, and in 30 patients, stable disease was the best outcome. The second cohort achieved a median PFS of 3.27 months and a median OS of 9.77 months. No complete or partial responses were observed, but 10 patients had stable disease. An unscheduled comparison of the first cohort of patients with 3,027 untreated patients with HCC from the Italian Liver Cancer (ITA.LI.CA) database was performed. One-to-one matching according to demographic/etiologic/oncologic features was possible for 50 patients. The median OS for these 50 capecitabine-treated patients was 15.6 months, compared with a median OS of 8.0 months for the matched untreated patients (p = .043). CONCLUSION: Metronomic capecitabine is well tolerated by patients with advanced HCC and appears to have activity both in treatment-naive patients and in those previously treated with sorafenib.

Adjuvant systemic chemotherapy after putative curative resection of colorectal liver and lung metastases.

OBJECTIVE: Marginal statistical evidence of efficacy of adjuvant and/or perioperative chemotherapy after resection of colorectal metastases exists, but formal recommendations are still lacking. The present study evaluated the adjuvant systemic chemotherapy after the first resection of liver and lung colorectal cancer metastases. PATIENTS AND METHODS: We retrospectively reviewed data of 181 consecutive unselected patients with R0 resection of colorectal metastases treated simultaneously at 2 institutions from 1997 to 2004. Patients > 75 years old, with an Eastern Cooperative Oncology Group Performance Status Score ≥ 2 or unfit for adjuvant chemotherapy were excluded from the analysis. The decision on chemotherapy after surgery was left to the patient in the absence of conclusive data on the efficacy of adjuvant chemotherapy in this setting. A total of 151 patients (131 with liver metastases, 20 with lung metastases), 78 of whom underwent adjuvant chemotherapy, were evaluable for disease-free survival (DFS) and overall survival. The main prognostic factors for DFS after resection of colorectal cancer metastases were investigated in univariate and multivariate analyses. RESULTS: At the univariate analysis, the number of resected lesions, lesion volume, disease-free interval and adjuvant systemic chemotherapy were the only significant prognostic factors. At multivariate analysis, only adjuvant chemotherapy and disease-free interval were independent prognostic factors (hazard ratios 1.66 and 1.62, respectively). The median DFS of patients who underwent systemic adjuvant chemotherapy was 16 months compared with 9.7 months for patients with observation alone (hazard ratio 1.56). Estimated 5-year DFS was 17.4% and 10.5% for treated and untreated patients, respectively. CONCLUSION: Adjuvant chemotherapy after metastasectomy in patients with colorectal cancer showed a significant benefit for DFS.

Asbestos: a hidden player behind the cholangiocarcinoma increase? Findings from a case-control analysis.

PURPOSES: We conducted a case-control analysis to explore the association between occupational exposure to asbestos and cholangiocarcinoma (CC). METHODS: The study was based on historical data from 155 consecutive patients with CC [69 intrahepatic CC (ICC) and 86 extrahepatic CC (ECC)] referred to Sant'Orsola-Malpighi University Hospital between 2006 and 2010. The cases were individually matched by calendar period of birth, sex, and region of residence to historical hospital and population controls. Occupational exposure to asbestos was retrospectively assessed considering job titles obtained from work histories. Separate conditional logistic regression models were applied for ECC and ICC. Estimates were adjusted for smoking status and socioeconomic class. RESULTS: We matched 149 controls (median birth year: 1947; males: 56 %) to 41 cases of ICC (median birth year: 1946; males: 56 %) and 212 controls (median birth year: 1945; males: 48 %) to 59 cases of ECC (median birth year: 1945; males 51 %); 53 cases were not matched due to residence or birth year. We found an increased risk of ICC in workers exposed to asbestos (adjusted OR 4.81, 95 % CI 1.73-13.33); we also observed suggestive evidence that asbestos exposure might be associated with ECC (adjusted OR 2.09, 95 % CI 0.83-5.27). Sensitivity analysis restricted to patients from the Province of Bologna produced confirmatory figures. CONCLUSIONS: Our findings suggest that ICC could be associated with asbestos exposure; a chronic inflammatory pathway is hypothesized. Exposure to asbestos could be one of the determinants of the progressive rise in the incidence of ICC during the last 30 years.

Antitumoral efficacy of the protease inhibitor gabexate mesilate in colon cancer cells harbouring KRAS, BRAF and PIK3CA mutations.

The employment of anti-epidermal growth factor receptor (EGFR) antibodies represents a backbone of the therapeutic options for the treatment of metastatic colorectal cancer (mCRC). However, this therapy is poorly effective or ineffective in unselected patients. Mutations in KRAS, BRAF and PIK3CA genes have recently emerged as the best predictive factors of low/absent response to EGFR-targeted therapy. Due to the need for efficacious treatment options for mCRC patients bearing these mutations, in this short report we examined the antitumoral activity of the protease inhibitor gabexate mesilate, alone and in combination with the anti-EGFR monoclonal antibody cetuximab, in a panel of human CRC cell lines harbouring a different expression pattern of wild-type/mutated KRAS, BRAF and PIK3CA genes. Results obtained showed that gabexate mesilate significantly inhibited the growth, invasive potential and tumour-induced angiogenesis in all the CRC cells employed in this study (including those ones harbouring dual KRAS/PIK3CA or BRAF/PIK3CA mutation), while cetuximab affected these parameters only in CRC cells with KRAS, BRAF and PIK3CA wild-type. Notably, the antitumoral efficacy of gabexate mesilate and cetuximab in combination was found to be not superior than that observed with gabexate mesilate as single agent. Overall, these preliminary findings suggest that gabexate mesilate could represent a promising therapeutic option for mCRC patients, particularly for those harbouring KRAS, BRAF and PIK3CA mutations, either as mono-therapy or in addition to standard chemotherapy regimens. Further studies to better elucidate gabexate mesilate mechanism of action in CRC cells are therefore warranted.

Second surgery or chemotherapy for relapse after radical resection of colorectal cancer metastases.

PURPOSE: Limited data suggest that second resections for colorectal cancer metastases may improve survival, but no study has compared surgery with chemotherapy in this setting. Therefore, we retrospectively compared the clinical outcome of potentially resectable patients who received a second metastasectomy with those who did not in our single-centre experience. METHODS: We retrospectively reviewed the clinical records of all patients treated for metastatic colorectal cancer in our centre over a period of 12 years. We selected patients who relapsed after radical resection of metastases from colorectal cancer and were deemed resectable again by our multidisciplinary team. We then compared the clinical outcome of those who received a second operation with those who refused surgery and also evaluated the role of prognostic factors. RESULTS: We identified 60 patients fulfilling the inclusion criteria. Twenty-nine underwent a second resection and 31 refused surgery. Median overall survival rates were 58.7 and 24.0 months, median times to progression were 14.4 and 6.6 months. Patients who received surgery plus perioperatory chemotherapy (18/29) had a significantly better outcome; 4/29 achieved long-term disease-free survival. CONCLUSIONS: Our study suggests that in highly selected metastatic colorectal cancer patients, a multimodal treatment plan, including a second resection, can achieve longer survival with respect to medical therapy.

Neoadjuvant treatment in rectal cancer: actual status.

Neoadjuvant (preoperative) concomitant chemoradiotherapy (CRT) has become a standard treatment of locally advanced rectal adenocarcinomas. The clinical stages II (cT3-4, N0, M0) and III (cT1-4, N+, M0) according to International Union Against Cancer (IUCC) are concerned. It can reduce tumor volume and subsequently lead to an increase in complete resections (R0 resections), shows less toxicity, and improves local control rate. The aim of this review is to summarize actual approaches, main problems, and discrepancies in the treatment of locally advanced rectal adenocarcinomas.

Durable complete response of hepatocellular carcinoma after metronomic capecitabine.

BACKGROUND: Hepatocellular carcinoma (HCC) is a highly vascular tumor which is poorly responsive to standard systemic chemotherapy. Recently, various antiangiogenic targeted agents have shown promising activity at different levels of evidence in patients with advanced HCC, suggesting that such treatments might be effective. CASE REPORT: Since chemotherapy administered with metronomic schedules inhibits angiogenesis, we treated a 64-year-old man with advanced HCC with metronomic capecitabine. After only two months of treatment the HCC nodules disappeared on ultrasonography. This finding was confirmed by a computed tomography scan. After more than three years the patient is still in treatment with minimal toxicity and maintains a complete remission. CONCLUSIONS: Our case report suggests that metronomic capecitabine may be effective in advanced HCC patients while being also well tolerated. This is important, given the frequent comorbidities of HCC patients.
