Background: The COICA study is an ambispective, observational trial that was conceived to assess the clinical course of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in cancer patients. A recently published, population-based, case-control study reported a reduced vaccine efficacy at 3–6 months in cancer patients compared to individuals without cancer. Objectives: The aim of the study was to describe coronavirus disease 19 (COVID-19) outcomes in cancer patients and analyze differences in SARS-CoV-2 outcomes between vaccinated and unvaccinated patients. Methods: Descriptive statistics and frequency counts were used to summarize characteristics of the study population. χ2 test and the log-rank test were used to compare outcomes between vaccinated and unvaccinated patients. Results: A total of 141 cancer patients (80 males, 61 females) were recruited at two participating Institutions from March 2020 until April 2022 and observed from the time of positive SARS-CoV-2 test to the time of negativization or death. Approximately 35% of patients had been vaccinated at the time of infection with 2 (16 patients) or 3 (33 patients) vaccine doses. Vaccinated patients consistently and significantly showed improved COVID-19 outcomes compared to unvaccinated patients, with CT-diagnosed pneumonia, hospitalization, O2 therapy, and death reported in 0% versus 48.6%, 2.0% versus 15.2%, 0% versus 14.1%, and 0% versus 7.6%, respectively, of assessable patients (p < 0.05). Vaccinated versus unvaccinated patients showed a significantly shorter time to negativization, with a median (95% confidence interval) time of 12 (10–14) versus 20 (17–23) days, respectively (p < 0.001). Conclusions: Vaccination consistently improved all COVID-19 outcomes. No death was recorded among vaccinated patients. Additional research is especially warranted to establish optimal timing and patient selection for administration of the fourth vaccination dose. [ABSTRACT FROM AUTHOR]

Introduction: Cancer aggravates COVID-19 prognosis. Nosocomial transmission of SARS-CoV-2 is particularly frequent in cancer patients, who need to attend hospitals regularly. Since March 2020, all cancer patients having access to the Oncology Unit at the "Andrea Tortora" Hospital (Pagani, Salerno – referred to as "the Hospital") as inpatients or outpatients receiving intravenous therapy have been screened for SARS-CoV-2 using RT-PCR nasal swab. The ongoing COICA (COVID-19 infection in cancer patients) study is an ambispective, multicenter, observational study designed to assess the prognosis of SARS-CoV-2 infection in cancer patients. The aim of the study presented here was to explore potential differences in COVID-19-related outcomes among screening-detected versus nonscreening-detected SARS-CoV-2-infected patients. Methods: The COICA study enrolled cancer patients who had received any anticancer systemic therapy within 3 months since the day they tested positive for SARS-CoV-2 on RT-PCR. The target accrual is 128 patients, and the study was approved by the competent Ethics Committee. Only the subgroup of patients enrolled at the Hospital was considered in this unplanned interim analysis. Logistic regression analysis was used to evaluate the association of screening-based versus nonscreening-based diagnosis. Results: Since March 15, 2020, until August 15, 2021, a total of 931 outpatients and 230 inpatients were repeatedly screened for SARS-CoV-2 using RT-PCR nasal swab at the Hospital. Among these, 71 asymptomatic patients were positive on routine screening and 5 patients were positive for SARS-CoV-2 outside the institutional screening. Seven patients died because of COVID-19. At univariate analysis, nonscreening- versus screening-detected SARS-CoV-2 infection was associated with significantly higher odds of O2 therapy (OR = 16.2; 95% CI = 2.2–117.1; p = 0.006), hospital admission (OR = 31.5; 95% CI = 3.1–317.8; p = 0.003), admission to ICU (OR = 23.0; 95% CI = 2.4–223.8; p = 0.007), and death (OR = 8.8; 95% CI = 1.2–65.5; p = 0.034). Conclusion: Routine screening with RT-PCR may represent a feasible and effective strategy in reducing viral circulation and possibly COVID-19 mortality in patients with active cancer having repeated access to hospital facilities.

Background: Immune-checkpoint inhibitors (ICIs) have increased and improved the treatment options for patients with non-oncogene-addicted advanced stage non-small cell lung cancer (NSCLC). However, the role of ICIs in oncogene-addicted advanced stage NSCLC patients is still debated. In this study, in an attempt to fill in the informational gap on the effect of ICIs on other driver mutations, we set out to provide a molecular landscape of clinically relevant oncogenic drivers in programmed death-ligand 1 (PD-L1) positive NSCLC patients. Methods: We retrospectively reviewed data on 167 advanced stage NSCLC PD-L1 positive patients (≥1%) who were referred to our clinic for molecular evaluation of five driver oncogenes, namely, EGFR, KRAS, BRAF, ALK and ROS1. Results: Interestingly, n = 93 (55.7%) patients showed at least one genomic alteration within the tested genes. Furthermore, analyzing a subset of patients with PD-L1 tumor proportion score (TPS) ≥ 50% and concomitant gene alterations (n = 8), we found that n = 3 (37.5%) of these patients feature clinical benefit with ICIs administration, despite the presence of a concomitant KRAS gene alteration. Conclusions: In this study, we provide a molecular landscape of clinically relevant biomarkers in NSCLC PD-L1 positive patients, along with data evidencing the clinical benefit of ICIs in patient NSCLC PD-L1 positive alterations.

Background: To date, the clinical characteristics of coronavirus disease 19 (COVID-19)-infected urologic cancer patients are unknown. Methods: We have analyzed all patients with prostate cancer undergoing hormonal or chemotherapy treatment and receiving telephone and in person pre-triage between March 1 and 27, 2020, at the Tortora Hospital, Pagani, Italy. Results: Among 72 patients, 48 and 24 were hormone-sensitive (HS) and castration-resistant prostate cancer (CRPC), respectively; 0 HS and 2 (8.3%) CRPC (p < 0.05) were positive for COVID-19. Both patients were receiving LHRH agonist therapy, and 1 patient was receiving enzalutamide. Urgent intensive care unit admission was required due to clinical worsening. Blood tests showed severe lymphopenia, anemia, and an increase in platelets. Retroviral therapy, antibiotics, heparin, and chloroquine were prescribed at the beginning. One patient also received tocilizumab as a salvage treatment. After 3 weeks of hospitalization, the patients were discharged from the hospital. Both patients suffered from an aggressive COVID-19 course due to concomitant comorbidities. Conclusions: Investigating whether hormonal therapy, especially in advanced disease, acts as a protective factor or a risk factor during COVID-19 could be useful. [ABSTRACT FROM AUTHOR]

Gemcitabine and 5-fluorouracil are the only two compounds with reproducible activity against advanced pancreatic cancer (APC). We have evaluated a novel combination of gemcitabine and 5-fluorouracil on the clinical benefit response (CBR) end point. Eleven consecutive patients with symptomatic APC were entered in a two-stage phase II trial. Gemcitabine was administered by intravenous (i.v.) bolus injection at the dose of 1000 mg m[SUP-2] on days 1, 8, 15 and 5-fluorouracil 500 mg m[SUP-2] was given by continuous i.v. infusion on days 1-5. Treatment was repeated every 28 days. A CBR was achieved in 7/11 patients. The mean time to loss of CBR was 26.5 weeks (range 14-18, median 22). Toxicity was mild and no APC patient experienced WHO grade 3 toxicity. The gemcitabine/5-fluorouracil combination is well tolerated and produces a symptomatic relief in the majority of APC patients.

The majority of testicular tumors are germ cell tumors (GCTs) which, although rare, frequently present in young adults. In exceptional circumstances, spontaneous regression of the primary tumor occurs. The appellation 'burned-out' is applied to situations in which a metastatic GCT is found to be present, accompanied by histological regression of the primary testicular lesion. It is of crucial importance that a clinical examination of the testis is performed, and scrotal sonography is essential in the preliminary diagnosis of such neoplasms. In the present case report, a burned-out, non-seminomatous testicular GCT case is described. A CT scan revealed that a 29-year-old male patient who was experiencing loss of weight and appetite had retroperitoneal and mediastinal masses. A testicular examination did not reveal the presence of any palpable lesion, and an ultrasound examination of the scrotum disclosed a normal left testis and an atrophic right testicle with heterogeneous architecture, but with no evidence of a tumor. Chemotherapy was administered to the patient following surgical intervention into the retroperitoneal and mediastinal mass. It is evident that it remains problematic to accurately differentiate between a primary retroperitoneal tumor and a metastatic testicular tumor with an occult testicular primary or a 'burned-out' testicular cancer. The burned-out phenomenon is a rare occurrence, and further research into its pathogenesis is required. Both the rarity of this phenomenon and the difficulties encountered in diagnosis prompted the writing of the present case report, especially considering that teratomas are categorized as belonging to the histology group that shows the least likelihood of regressing.
