Coronavirus disease-2019 in cancer patients. A report of the first 25 cancer patients in a western country (Italy).

Background: We describe cancer patients with coronavirus disease-2019 (COVID-19) infection treated at the Piacenza's general hospital (north Italy). Materials & methods: 25 cancer patients infected by COVID-19 admitted at the Piacenza's general hospital from 21 February to 18 March 2020. Outcome from the infection were compared with infected noncancer patients. Results: 20 patients (80%) were treated with antiviral therapy and hydroxychloroquine and five (20%) received hydroxychloroquine alone. Nine (36%) patients died, while 16 (64%) overcome the infection. In the control group the mortality was 16.13% and the overcome from infection was 83.87%. Conclusion: Mortality for COVID-19 was greater in cancer patients when compared with noncancer patients, worse prognosis for older age, women and patients treated with hydroxychloroquine alone. However, the comparisons did not reach statistical significance in most cases. This could be due to the small sample size that is the main limitation of the study.

Advanced gastric cancer with liver and lymph node metastases successfully resected after induction chemotherapy with docetaxel, cisplatin and 5-fluorouracil.

BACKGROUND: At diagnosis, about 35% of patients with gastric cancer present with distant metastases, and most patients with gastric cancer and liver metastases are excluded from curative surgery. CASE: We report a case of human epidermal growth factor receptor-2 (HER2)-negative gastric cancer with metastases to the liver and perigastric lymph nodes. The patient (a 60-year-old man) was considered unresectable at diagnosis and was treated with palliative chemotherapy (docetaxel plus cisplatin and 5-fluorouracil by continuous intravenous infusion over 5 days every 3 weeks). However, after 6 courses of chemotherapy, a computed tomography scan showed a reduction of the liver metastasis and the disappearance of the enlarged perigastric lymph nodes. The patient then underwent a curative gastrectomy, lymphadenectomy and liver resection. After surgery, the patient was treated with 6 courses of FOLFOX-4 regimen as adjuvant chemotherapy. With a follow-up of 26 months after surgery, the patient is alive and disease free. CONCLUSION: In patients with metastatic gastric cancer, the prognosis is poor with a median overall survival of 11 months since curative treatments are excluded; however, this case illustrated that a personalized treatment with chemotherapy and surgery can allow a curative strategy in selected patients with HER2-negative advanced gastric cancer.

Ultrasound guidance reduces pneumothorax rate and improves safety of thoracentesis in malignant pleural effusion: report on 445 consecutive patients with advanced cancer.

BACKGROUND: Malignant pleural effusion (MPE) is an extremely common problem affecting cancer patients, and thoracentesis is an essential procedure in an attempt to delineate the etiology of the fluid collections and to relieve symptoms in affected patients. One of the most common complications of thoracentesis is pneumothorax, which has been reported to occur in 20% to 39% of thoracenteses, with 15% to 50% of patients with pneumothorax requiring tube thoracostomy.The present study was carried out to assess whether thoracenteses in cancer patients performed with ultrasound (US) guidance are associated with a lower rates of pneumothorax and tube thoracostomy than those performed without US guidance. METHODS: A total of 445 patients were recruited in this retrospective study. The medical records of 445 consecutive patients with cancer and MPE evaluable for this study, undergoing thoracentesis at the Oncology-Hematology and Internal Medicine Departments, Piacenza Hospital (Italy) were reviewed. RESULTS: From January 2005 to December 2011, in 310 patients (69.66%) thoracentesis was performed with US guidance and in 135 (30.34%) without it. On post-thoracentesis imaging performed in all these cases, 15 pneumothoraces (3.37%) were found; three of them (20%) required tube thoracostomy. Pneumothorax occurred in three out of 310 procedures (0.97%) performed with US guidance and in 12 of 135 procedures (8.89%) performed without it (P<0.0001). It must be emphasized that in all three patients with pneumothorax requiring tube thoracostomy, thoracentesis was performed without US guidance. CONCLUSIONS: The routine use of US guidance during thoracentesis drastically reduces the rate of pneumothorax and tube thoracostomy in oncological patients, thus improving safety as demonstrated in this study.

FOLFIRINOX or Gemcitabine Plus Nab-paclitaxel as First Line Treatment in Pancreatic Cancer: A Real-World Comparison.

Background/Aim: Advanced pancreatic cancer has a poor prognosis and a 5-year survival rate <5%; thus, treatment of patients with advanced unresectable or metastatic disease is challenging. Current guidelines recommend either gemcitabine plus nab-paclitaxel (GnP) or FOLFIRINOX (FOL) as first-line treatment. Data on both efficacy and toxicity of FOL versus GnP in metastatic cancer are limited. This study aimed to compare the two chemotherapy regimens in terms of efficacy and toxicity in a real-world setting. Patients and Methods: This retrospective propensity score matching study reviewed the medical records of 123 consecutive patients with advanced or metastatic pancreatic cancer who received either GnP or FOL between March 2013 and January 2019 in Guglielmo da Saliceto Hospital, Piacenza. Results: Fifty patients (40.65%) received FOL, administered in an attenuated dose, and seventy-three patients (59.35%) received GnP. After a propensity matching score, 100 patients were retrospectively evaluated. In the final matched cohort, there was no difference in neoadjuvant therapy, radiotherapy, and surgery performed before the first-line therapy between the two groups. Progression-free survival and overall survival were comparable between the two groups and no difference was found in the percentage of toxicity. Conclusion: There was no difference in outcomes between patients who received FOL and those who received GnP. Unexpectedly, no greater FOL-related toxicity was found, probably due to the dose reduction.

Unraveling the Interplay of KRAS, NRAS, BRAF, and Micro-Satellite Instability in Non-Metastatic Colon Cancer: A Systematic Review.

Microsatellite Instability (MSI-H) occurs in approximately 15% of non-metastatic colon cancers, influencing patient outcomes positively compared to microsatellite stable (MSS) cancers. This systematic review focuses on the prognostic significance of KRAS, NRAS, and BRAF mutations within MSI-H colon cancer. Through comprehensive searches in databases like MEDLINE, EMBASE, and others until 1 January 2024, we selected 8 pertinent studies from an initial pool of 1918. These studies, encompassing nine trials and five observational studies involving 13,273 patients, provided insights into disease-free survival (DFS), survival after recurrence, and overall survival. The pooled data suggest that while KRAS and BRAF mutations typically predict poorer outcomes in MSS colorectal cancer, their impact is less pronounced in MSI contexts, with implications varying across different stages of cancer and treatment responses. In particular, adverse effects of these mutations manifest significantly upon recurrence rather than affecting immediate DFS. Our findings confirm the complex interplay between genetic mutations and MSI status, emphasizing the nuanced role of MSI in modifying the prognostic implications of KRAS, NRAS, and BRAF mutations in colon cancer. This review underscores the importance of considering MSI alongside mutational status in the clinical decision-making process, aiming to tailor therapeutic strategies more effectively for colon cancer patients.

Targeting FGFR Pathways in Gastrointestinal Cancers: New Frontiers of Treatment.

In carcinogenesis of the gastrointestinal (GI) tract, the deregulation of fibroblast growth factor receptor (FGFR) signaling plays a critical role. The aberrant activity of this pathway is described in approximately 10% of gastric cancers and its frequency increases in intrahepatic cholangiocarcinomas (iCCAs), with an estimated frequency of 10-16%. Several selective FGFR inhibitors have been developed in the last few years with promising results. For example, targeting the FGFR pathway is now a fundamental part of clinical practice when treating iCCA and many clinical trials are ongoing to test the safety and efficacy of anti-FGFR agents in gastric, colon and pancreatic cancer, with variable results. However, the response rates of anti-FGFR drugs are modest and resistances emerge rapidly, limiting their efficacy and causing disease progression. In this review, we aim to explore the landscape of anti-FGFR inhibitors in relation to GI cancer, with particular focus on selective FGFR inhibitors and drug combinations that may lead to overcoming resistance mechanisms and drug-induced toxicities.

Nine-Week Versus One-Year Trastuzumab for Early Human Epidermal Growth Factor Receptor 2-Positive Breast Cancer: 10-Year Update of the ShortHER Phase III Randomized Trial.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned coprimary or secondary analyses are not yet available. Clinical trial updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.We present the final analysis of the phase III noninferiority, randomized ShortHER trial comparing 9 weeks versus 1 year of adjuvant trastuzumab with chemotherapy in patients with human epidermal growth factor receptor 2-positive (HER2+) early breast cancer (BC). Women with HER2+ BC were randomly assigned to anthracycline-taxane combinations plus 1-year trastuzumab (arm A, long) or 9-week trastuzumab (arm B, short). Here, we report the second coprimary end point overall survival (OS), updated disease-free survival (DFS), and outcomes according to hormone receptor status, age, and nodal status. At a median follow-up of 9 years, 10-year DFS is 77% versus 78% in the long versus short arm, respectively. Ten-year OS is 89% versus 88% in the long versus short arm, respectively. 10-year DFS rates in the long versus short arm according to nodal status are N0 81% versus 85%; N1-3 77% versus 79%; and N4+ 63% versus 53%. Ten-year OS rates in long versus short arm according to nodal status are N0 89% versus 95%%; N1-3 92% versus 89%; and N4+ 84% versus 64%. The updated analysis of the ShortHER trial shows that 1-year trastuzumab is the standard treatment for patients with HER2+ early BC as noninferiority cannot be claimed. However, numerically, the differences for the patients at low or intermediate risk (N0/N1-3) is negligible, while patients with N4+ have a clear benefit with 1-year trastuzumab.

COVID-19 Vaccination in Cancer Patients Older Than 70 Years Undergoing Active Treatment. Seroconversion Rate and Safety.

Patients with cancer have a high risk of intubation, intensive care unit admission, or death from the coronavirus disease (COVID-19); age and comorbidities are additional risk factors. Vaccination is effective against COVID-19; however, patients with cancer have been excluded from pivotal clinical trials for COVID-19 vaccines. Data on COVID-19 vaccination in cancer patients who are older are lacking. This observational study was conducted to evaluate the seropositivity rate and safety of a two-dose regimen of the BNT162b2 or mRNA1273 vaccine in older patients (age ≥ 70 years) with solid tumors or with hematological malignances who are undergoing active anticancer treatment or whose treatment has been terminated within 6 months of vaccination. The control group was composed of healthy volunteers that were age-matched with the patient group. The primary endpoint was the seropositivity rate, and the secondary endpoints were safety, the factors influencing seroconversion, the IgG titers of patients versus healthy volunteers, and post-vaccine COVID-19 infection between 20 March 2021 and 14 July 2021. At our Institution (Oncology and Hematology Department, Hospital of Piacenza, North Italy), 443 patients with cancer underwent a program for COVID-19 vaccination; 115 (25.95%) were older than 70 (range 71-86 years) and form the basis of this study. All 115 patients accepted the vaccination. There were 64 female patients (55.65%), 94 patients (81.74%) with solid tumors, and 21 patients (18.26%) with hematological malignances. The primary endpoint of seropositivity was observed in 75 patients (65.22%)-70.21% in patients with solid tumors and 42.86% in patients with hematological malignances-versus in 100% of patients in the control group. Of the secondary endpoints, no grade 3-4 side effects and no COVID-19 infections were reported. The factor influencing seroconversion was the type of cancer. The patients' median IgG titers were significantly lower than in the control groups. The COVID-19 vaccines BNT162b2 and mRNA1273 were effective and safe among older patients with cancer when administered in real-world conditions.

Elderly cancer patients' preferences regarding the disclosure of cancer diagnosis. Experience of a single institution in Italy.

The disclosure of a diagnosis of cancer is complex, particularly in older patients for reasons related to the wishes of the family, fear of discouraging the patient, or the patient's inability to understand the information. So our insight into older people's perspectives regarding the disclosure of their cancer diagnosis is fragmentary and inadequate. To examine the views of older adults regarding this issue, we performed a prospective observational study in an inpatient oncology clinic. From January 2006 to June 2006, a sample of 132 consecutive cancer patients aged over 70 years with a variety of solid tumors, recently diagnosed and mainly at an advanced stage, agreed to take part in a survey about the disclosure of the diagnosis of their disease. Of the 132 patients who verbally agreed to participate and were given questionnaires, 106 returned data. The majority of patients (64.1%) in this study wanted to be informed about the diagnosis of their disease also if it was cancer, and 58.5% were in fact informed about the exact nature of their disease. Male patients were more keen to know the diagnosis than female patients (P = 0.002) and they were in fact more informed about their diagnosis than female patients (P = 0.005). Patients with more formal education were more informed than patients with less formal education (P = 0.035). This study demonstrates that the preferences of older patients regarding cancer diagnosis disclosure are highly similar to those of younger people. Male patients and patients with more formal education were more informed than female patients and patients with less formal education.

Cancer diagnosis disclosure in a northern Italian hospital. Report on 312 consecutive cancer patients.

To evaluate cancer diagnosis disclosure in a cohort of cancer patients attending an outpatient oncology unit, a prospective observational study was performed. Three hundred twelve consecutive patients were accrued between January and June 2005. A questionnaire was given to each patient; the questions were very simple and related to demographics, residence, sex, educational background, employment status, time elapsed after diagnosis, treatment received, existence of relatives, and health insurance. All patients but one entered the study. There were 185 women and 127 men; 120 patients had breast cancer, 84 colorectal cancer, 34 lung cancer, 28 ovarian cancer, 34 gastric cancer, and 12 pancreatic cancer. Of the total 311 evaluable cancer patients, 171 (54.98%) were correctly informed; of the remaining 140 patients, 67 (21.54%) were not sure, and 73 (23.47%) thought their disease was not cancer. These data suggest that the majority of cancer patients attending our outpatient oncology unit are being correctly informed about their diagnosis. In our series the type of tumor had an important impact on diagnosis disclosure, while age and educational status did not.

Role of anti-hepatitis C virus (HCV) treatment in HCV-related, low-grade, B-cell, non-Hodgkin's lymphoma: a multicenter Italian experience.

PURPOSE: Hepatitis C virus (HCV) is endemic in some areas of Northwestern Europe and the United States. HCV has been shown to play a role in the development of both hepatocellular carcinoma and B-cell non-Hodgkin's lymphoma (B-NHL). The biologic mechanisms underlying the lymphomagenic activity of the virus so far are under investigation. In this study, the role of antiviral (anti-HCV) treatment in B-NHL associated with HCV infection is evaluated. PATIENTS AND METHODS: Thirteen patients with histologically proven low-grade B-NHL characterized by an indolent course (ie, doubling time no less than 1 year, no bulky disease) and carrying HCV infection were enrolled on the study. All patients underwent antiviral treatment alone with pegilated interferon and ribavirin. Response assessment took place at 6 and 12 months. RESULTS: Of the twelve assessable patients, seven (58%) achieved complete response and two (16%) partial hematologic response at 14.1 +/- 9.7 months (range, 2 to 24 months, median follow-up, 14 months), while two had stable disease with only one patient experiencing progression of disease. Hematologic responses (complete and partial, 75%) were highly significantly associated to clearance or decrease in serum HCV viral load following treatment (P = .005). Virologic response was more likely to be seen in HCV genotype 2 (P = .035), while hematologic response did not correlate with the viral genotype. Treatment-related toxicity did not cause discontinuation of therapy in all but two patients, one of whom, however, achieved complete response. CONCLUSION: This experience strongly provides a role for antiviral treatment in patients affected by HCV-related, low-grade, B-cell NHL.

Post-traumatic glioma: report of two cases.

We report two cases of brain glioma that developed in the scar of an old brain trauma. The first is that of a 40-year-old man who presented with severe headaches; CT and MRI showed a large mass in the right parietal region. The tumor was unresectable and surgical biopsy showed a glioblastoma multiforme. The patient had suffered a cranial trauma in a road accident 20 years previously with an intrathecal hematoma in the right parietal region. The second case concerns a 60-year-old man who, 15 years after severe head injury in a road accident, developed a glioblastoma multiforme which was localized in the scar of the brain contusion. These cases fulfill the established criteria for a traumatic origin of brain tumors and add further support to the relationship between cranial trauma and the onset of glioma. As stated by other authors, an association between head trauma and brain tumor risk cannot be ruled out and should be studied further.

Primary pancreatic lymphoma. Report of five cases.

Primary pancreatic lymphoma (PPL) is a very rare disease. We report five cases of PPL (4 men and 1 woman, mean age 65 years) diagnosed and treated at our Institution from 1987 to 1997. None of these patients had evidence of extrapancreatic disease and they were categorized as PPL involving pancreas only (stage IE, 3 patients) or pancreas and peripancreatic lymph nodes (stage IIE, 2 patients). The most common presenting symptoms were abdominal pain and weight loss. Imaging techniques showed a mass of the pancreatic head in all cases. The histological diagnosis (3 diffuse-large cell non-Hodgkin's lymphoma and 2 lymphoplasmacytic lymphoma/immunocytoma) was made by ultrasound-guided fine needle aspiration biopsy and tissue core fine-needle biopsy in three patients and by surgery in the remaining two patients. The three patients diagnosed by percutaneous biopsy were treated with chemotherapy as front-line therapy and two of them received also local radiotherapy; one of these patients is still alive in complete remission at 69 months, one died of an unrelated disease at 67 months and one died of lymphoma relapse at 88 months. Two patients underwent pancreaticoduodenectomy plus adjuvant chemotherapy; one of them died of recurrent cholangitis 8 months after surgery while the other one is still alive in complete remission after 160 months. This study shows that: 1) imaging techniques can suggest the suspicion of PPL but are unable to distinguish PPL from pancreatic adenocarcinoma; 2) histological diagnosis can be easily obtained by percutaneous US-guided tissue core biopsy; 3) surgery can be avoided both for diagnosis and therapy but the treatment of choice of PPL may only be evaluated on a larger series of patients.

[Thrombotic thrombocytopenic purpura: report of seven cases]. / Porpora trombotica trombocitopenica: descrizione di sette casi.

From May 1999 to January 2002 we observed 7 patients (4 females and 3 males, median age 55 years, range 31-81 years) with thrombotic thrombocytopenic purpura (TTP). Six patients has been previously undiagnosed and 1 patient was at second relapse. Trigger factors of TTP were identified in 6 patients: ticlopidine treatment (2 patients); an acute cutaneous infection episode immediately before the features of TTP (1 patient); presence of devices: orthodontic (1 patient) and intrauterine contraceptive (1 patient), Mycoplasma urealyticum vaginal infection (1 patient). In all the 7 patients the clinical status was mainly related to the hemolytic anemia, thrombocytopenia and neurological events. One of these patients presented with hemolytic-uremic syndrome with acute renal failure and macrohematuria at onset, another one showed a systemic exanthema post-infection-like. Six out of 7 patients presented with different neurological events: headache, confusion, focal neurological failure. All the 7 patients were promptly treated with plasma-exchange and cryosupernatant plasma infusion. In addition they received prednisone 25-50 mg/day. All the 7 patients achieved a complete remission after plasma-exchange, one relapsed 3 months later and was treated with plasma-exchange again. All the patients are in complete remission with a median follow-up of 36.3 months (range 20-62 months). From these cases we suggest: 1) clinicians should take in mind the suspicion of TTP in every patient with hemolytic, negative direct Coombs test, anemia, thrombocytopenia, high level of lactate dehydrogenase; 2) the treatment of choice is plasma-exchange; 3) the response of treatment is good if therapy is promptly and aggressively administered; 4) the possible role of a trigger factor for removing it and to prevent relapses.

Safety and efficacy of enoxaparin treatment in venous thromboembolic disease during acute leukemia.

BACKGROUND: Venous thromboembolism (VTE) is a quite common complication in acute leukemia, although its real incidence is unknown. The best treatment of this complication is still a matter of debate due to the very high risk of hemorrhage in this group of patients. PATIENTS AND METHODS: From December 2000 to December 2002 four Caucasian patients with acute leukemia developed VTE complications. The patients were three men and one woman, mean age 55.7 years (range, 27-77). Two patients with acute lymphoid leukemia (L1 and L2 according to the FAB classification) developed deep venous thrombosis during the administration of chemotherapy; one patient with acute myeloid leukemia (AML, M2 according to the FAB classification) had pulmonary thromboembolism at diagnosis, while another AML patient (M4 according to FAB) showed deep venous thrombosis as the first symptom of leukemia. The clinical diagnosis of symptomatic VTE was confirmed by objective imaging procedures including lower limb venous color Doppler imaging in all cases and a ventilation-perfusion lung scan in one case. All patients were treated with enoxaparin 100 IU/kg subcutaneously twice daily for one month, followed by 150 IU/kg once daily for at least five months. When the platelet count was below 20,000 x 10(9)/L, the dose was reduced by 50%. RESULTS: During antithrombotic treatment neither VTE recurrences nor hemorrhagic complications or heparin-induced thrombocytopenia occurred. The platelet count at the beginning of enoxaparin treatment was very low (mean, 55,750 x 109/L; range, 12,000-121,000 x 10(9)/L) and treatment did not affect platelet recovery. CONCLUSIONS: Enoxaparin proved to be efficacious and safe in the management of deep venous thrombosis with or without pulmonary embolism in patients affected by acute leukemia. Enoxaparin cured acute venous thrombosis, prevented recurrences and did not cause any hemorrhagic complications despite prolonged severe thrombocytopenia.

HER2-positive gastric cancer showing marked thickening of the gastric wall on ultrasonographic and computed tomographic scans. a chance phenomenon or a specific behaviour of this cancer type? Report of three cases.

Worldwide, gastric cancer is the fourth most commonly diagnosed type of cancer and the second most common cause of cancer-related death. Recently, it was demonstrated that 15-20% of advanced gastro-oesophageal carcinomas overexpress human epidermal receptor 2 (HER2), one of a family of four identified human epidermal receptors. As in HER2-positive breast cancer, trastuzumab, a monoclonal antibody targeting HER2 receptor, with chemotherapy improves prognosis, time-to-progression and overall survival in patients with advanced gastric cancer. Computed tomography (CT) and ultrasound (US) imaging of gastric cancer has been previously reported, however, to our knowledge HER2-positive gastric adenocarcinoma appearance on US and CT scans has not been previously described and no CT and US images of this variant of adenocarcinoma have been found. We herein report three cases of patients with HER2-positive gastric cancer that showed a marked thickening of the gastric wall on US and CT examination.

Long-term results of preoperative 5-fluorouracil-oxaliplatin chemoradiation therapy in locally advanced rectal cancer.

AIM: To evaluate the activity, safety and long-term survival of patients after preoperative oxaliplatin and 5-fluorouracil chemoradiation therapy in locally advanced rectal cancer (LARC). PATIENTS AND METHODS: Patients with resectable, T3-4 and/or nodal involvement rectal adenocarcinoma were treated with oxaliplatin 60 mg/m(2) weekly and 5-fluorouracil 200 mg/m(2)/d infused continuously for five days, over a period of five weeks, and radiotherapy (45 Gy/25 fractions). The primary end-point was pathological complete response (ypCR). Safety, overall survival (OS) and relapse-free survival (RFS) were secondary end-points. RESULTS: Sixty-six patients were treated. Grade 1-2 diarrhea was the most common adverse event. The ypCR rate was 16.7% (95% confidence interval=7.7-25.7%). After a median follow-up of 73.5 months, 23 patients (34.8%) had experienced relapse. Five-year actuarial RFS and OS rates were 64% and 73%, respectively. Five-year actuarial RFS was 91.7% in the ypCR group versus 57.8% in non-ypCR cases. CONCLUSION: Long-term local control and survival after this very well-tolerated regimen appear encouraging.
