Hyperthermic intraperitoneal chemotherapy and colorectal cancer: From physiology to surgery.

The pursuit of this paper is to collect principal reviews and systematic reviews about hyperthermic intraperitoneal chemotherapy (HIPEC) and cytoreductive surgery (CRS) used in colorectal cancer (CRC). We focus on principal biological aspects of CRC, hyperthermia effects, and surgical procedures. We searched PubMed/MEDLINE for the principal reviews and systematic reviews published from 2010 to 2021 regarding the bimodal treatment (CRS + HIPEC) against local and advanced CRC.

Anti-PD1 antibodies in patients aged ≥ 75 years with metastatic melanoma: A retrospective multicentre study.

Background: Advanced age is associated with comorbidities and immune system impairment, which may influence the efficacy and tolerability of immune checkpoint inhibitors. There is evidence that anti-PD1 antibodies in advanced melanoma are equally effective in patients >65 years. However, data on patients >75 years are lacking as co-morbidities and logistics often exclude them from clinical trials.

The Management of Oligoprogression in the Landscape of New Therapies for Metastatic Melanoma.

: A limited degree of progression after a response to treatment is labelled as oligoprogression and is a hot topic of metastatic melanoma (MM) management. Rogue progressive metastases could benefit from local treatment, which could allow the continuation of ongoing systemic therapy, also known as treatment beyond progression (TBP). : We retrospectively reviewed 214 selected MM patients who developed oligoprogression during treatment with v-Raf murine sarcoma viral oncogene homolog B (BRAF)/mitogen-activated-extracellular signal-regulated kinase (MEK) or programmed cell death protein 1 (PD-1) inhibitors and received a local treatment continuing TBP.

Translational control mechanisms in cutaneous malignant melanoma: the role of eIF2α.

Background: Melanoma cells develop adaptive responses in order to cope with particular conditions of tumor microenvironment, characterized by stress conditions and deregulated proliferation. Recently, the interplay between the stress response and the gene expression programs leading to metastatic spread has been reported.

Methods: We evaluated levels and localization of eIF2α/peIF2α in V600BRAF and wtBRAF metastatic melanoma cell lines by means of western blot and confocal microscopy analyses.

The search for a melanoma-tailored chemotherapy in the new era of personalized therapy: a phase II study of chemo-modulating temozolomide followed by fotemustine and a cooperative study of GOIM (Gruppo Oncologico Italia Meridionale).

Background: It is frequently asked whether chemotherapy can still play a role in metastatic melanoma considering the effectiveness of the available drugs today, including antiCTLA4/antiPD1 immunotherapy and antiBRAF/antiMEK inhibitors. However, only approximately half of patients respond to these drugs, and the majority progress after 6-11 months. Therefore, a need for other therapeutic options is still very much apparent.

Practical issues for the management of hyponatremia in oncology.

Hyponatremia is common in cancer patients and has a negative impact on outcomes and survival. Both the diagnosis and treatment of hyponatremia are challenging. Easy-to-use, practical guidelines are needed.

Prevalence of malnutrition in patients at first medical oncology visit: the PreMiO study.

Background: In cancer patients, malnutrition is associated with treatment toxicity, complications, reduced physical functioning, and decreased survival. The Prevalence of Malnutrition in Oncology (PreMiO) study identified malnutrition or its risk among cancer patients making their first medical oncology visit. Innovatively, oncologists, not nutritionists, evaluated the nutritional status of the patients in this study.

Role of bone marrow biopsy in staging of patients with classical Hodgkin's lymphoma undergoing positron emission tomography/computed tomography.

Several studies suggested that staging bone marrow biopsy (BMB) could be omitted in patients with classical Hodgkin's lymphoma (cHL) when a positron emission tomography/computed tomography (PET/CT) is performed at baseline.To address the concordance between BMB and PET/CT in the detection of bone marrow involvement (BMI) and the BMB role in determining the Ann Arbor stage, we retrospectively collected data on 1244 consecutive patients with cHL diagnosed from January 2007 to December 2013. One thousand eighty-five patients who had undergone both BMB and PET/CT were analyzed, comparing the Ann Arbor stage assessed with PET/CT only to that resulting from PET/CT combined with BMB.

Breakthrough Cancer Pain: Preliminary Data of The Italian Oncologic Pain Multisetting Multicentric Survey (IOPS-MS).

Introduction: An ongoing national multicenter survey [Italian Oncologic Pain multiSetting Multicentric Survey (IOPS-MS)] is evaluating the characteristics of breakthrough cancer pain (BTP) in different clinical settings. Preliminary data from the first 1500 cancer patients with BTP enrolled in this study are presented here.

Methods: Thirty-two clinical centers are involved in the survey.

New insight into the role of metabolic reprogramming in melanoma cells harboring BRAF mutations.

This study explores the BRAF-MITF-PGC-1α axis and compares metabolic and functional changes occurring in primary and metastatic BRAF melanoma cell lines. BRAF mutations in homo/heterozygosis were found to be correlated to high levels of pERK, to downregulate PGC-1α/β, MITF and tyrosinase activity, resulting in a reduced melanin synthesis as compared to BRAFwt melanoma cells. In this scenario, BRAF switches on a metabolic reprogramming in melanoma, leading to a decreased OXPHOS activity and increased glycolytic ATP, lactate, HIF-1α and MCT4 levels.

Detrimental effects of melanocortin-1 receptor (MC1R) variants on the clinical outcomes of BRAF V600 metastatic melanoma patients treated with BRAF inhibitors.

Melanocortin-1 receptor (MC1R) plays a key role in skin pigmentation, and its variants are linked with a higher melanoma risk. The influence of MC1R variants on the outcomes of patients with metastatic melanoma (MM) treated with BRAF inhibitors (BRAFi) is unknown. We studied the MC1R status in a cohort of 53 consecutive BRAF-mutated patients with MM treated with BRAFi.

Prolonged Drainage and Intrapericardial Bleomycin Administration for Cardiac Tamponade Secondary to Cancer-Related Pericardial Effusion.

Malignant pericardial effusion (MPE) is a serious complication of several cancers. The most commonly involved solid tumors are lung and breast cancer. MPE can give rise to the clinical picture of cardiac tamponade, a life threatening condition that needs immediate drainage.

Progression-free survival as surrogate end point for overall survival in clinical trials of HER2-targeted agents in HER2-positive metastatic breast cancer.

Background: The gold standard end point in randomized clinical trials in metastatic breast cancer (MBC) is overall survival (OS). Although therapeutics have been approved based on progression-free survival (PFS), its use as a primary end point is controversial. We aimed to assess to what extent PFS may be used as a surrogate for OS in randomized trials of anti-HER2 agents in HER2+ MBC.

Neoadjuvant multimodal treatment of pancreatic ductal adenocarcinoma.

Treatment of pancreatic ductal adenocarcinoma (PDAC) is increasingly multidisciplinary, with neoadjuvant strategies (chemotherapy, radiation, and surgery) administered in patients with resectable, borderline resectable, or locally advanced disease. The rational supporting this management is the achievement of both higher margin-negative resections and conversion rates into potentially resectable disease and in vivo assessment of novel therapeutics. International guidelines suggest an initial staging of the disease followed by a multidisciplinary approach, even considering the lack of a treatment approach to be considered as standard in this setting.

Role of WB-MR/DWIBS compared to (18)F-FDG PET/CT in the therapy response assessment of lymphoma.

Introduction: This study prospectively evaluated whole-body magnetic resonance/diffusion-weighted imaging with body signal suppression (WB-MR/DWIBS) reliability compared to (18)F-FDG PET/CT in the treatment response assessment of classic Hodgkin lymphomas (HL) and aggressive non-Hodgkin lymphomas (aNHL).

Materials And Methods: Twenty-seven consecutive patients were prospectively enrolled at the time of diagnosis. Eighteen (11 HL and seven aNHL) were considered for the analysis.

Ocular Toxicity in Metastatic Melanoma Patients Treated With Mitogen-Activated Protein Kinase Kinase Inhibitors: A Case Series.

Purpose: To report the clinical features and management of mitogen-activated protein kinase kinase inhibitor-associated ocular side effects in 4 patients with advanced melanoma and a review of literature.

Design: Interventional case series.

Methods: Four patients with advanced cutaneous melanoma were treated with a mitogen-activated protein kinase kinase (MEK) inhibitor as single therapy or together with a v-raf murine sarcoma viral oncogene homolog B1 (BRAF) inhibitor.

Hepatocellular carcinoma treatment over sorafenib: epigenetics, microRNAs and microenvironment. Is there a light at the end of the tunnel?

Introduction: Sorafenib is currently the only approved therapy in hepatocellular carcinoma (HCC). Alternative first- and second-line treatments are a significant unmet medical need, and several biologic agents have been tested in recent years, with poor results. Therefore, angiogenic pathways and the cytokine cascade remain possible targets in HCC.

Long-term response of gemcitabine plus docetaxel chemotherapy regimen for extraskeletal osteosarcoma: A case report.

Extraskeletal osteosarcomas (EOSs) are rare variants of primary osteosarcoma of the bone, and are defined as sarcomas located in the soft tissues and characterized by osteoid production. EOS exhibits distinctive demographic, imaging and prognostic features compared with osteosarcoma of bone origin. The available data are contradictory with regard to the use of chemotherapy regimens in the management of EOS.

Italian multicenter survey to evaluate the opinion of patients and their reference clinicians on the "tolerance" to targeted therapies already available for non-small cell lung cancer treatment in daily clinical practice.

Introduction: The introduction of targeted therapies in non-small cell lung cancer (NSCLC) treatment has led to emerging toxicities, whose management and impact on quality-of-life (QoL) is not clearly defined. Aim of this Italian multicenter survey was to highlight any discrepancy between patients' and clinicians' perception of such toxicities in order to improve their management.

Methods: From October 2013 to April 2014, 133 NSCLC advanced patients, treated with targeted therapies, were consecutively enrolled to assess toxicities and QoL with dedicated questionnaires.

Metronomic chemotherapy from rationale to clinical studies: a dream or reality?

Metronomic chemotherapy (MC) refers to the close administration of a chemotherapeutic drug for a long time with no extended drug-free breaks. It was developed to overcome drug resistance, partly by shifting the therapeutic target from tumor cells to the tumor vasculature, with less toxicity. Because of this peculiar way of administration, MC can be viewed as a form of long-term 'maintenance' treatment, and can be integrated with standard and conventional chemotherapy in a "chemo-switching" strategy.

Bone metastases in patients with metastatic renal cell carcinoma: are they always associated with poor prognosis?

Purpose: Aim of this study was to investigate for the presence of existing prognostic factors in patients with bone metastases (BMs) from RCC since bone represents an unfavorable site of metastasis for renal cell carcinoma (mRCC).

Materials And Methods: Data of patients with BMs from RCC were retrospectively collected. Age, sex, ECOG-Performance Status (PS), MSKCC group, tumor histology, presence of concomitant metastases to other sites, time from nephrectomy to bone metastases (TTBM, classified into three groups: <1 year, between 1 and 5 years and >5 years) and time from BMs to skeletal-related event (SRE) were included in the Cox analysis to investigate their prognostic relevance.

Azacitidine in the front-line treatment of therapy-related myeloid neoplasms: a multicenter case series.

Background/aim: A continued increase in the incidence of therapy-related myeloid neoplasms (t-MN) is expected due to the improvement of chemotherapeutic treatments for solid and haematological malignancies. The use of 5-azacytidine (AZA) is emerging in these patients. We, therefore, analyzed the outcome of patients with t-MN ineligible for intensive chemotherapy treated in the front-line with AZA.

The scaffolding protein NHERF1 sensitizes EGFR-dependent tumor growth, motility and invadopodia function to gefitinib treatment in breast cancer cells.

Triple negative breast cancer (TNBC) patients cannot be treated with endocrine therapy or targeted therapies due to lack of related receptors. These patients overexpress the epidermal growth factor receptor (EGFR), but are resistant to tyrosine kinase inhibitors (TKIs) and anti-EGFR therapies. Mechanisms suggested for resistance to TKIs include EGFR independence, mutations and alterations in EGFR and in its downstream signalling pathways.
