Among neuroendocrine neoplasms (NENs), a non-negligible proportion (9-22%) is represented by sufferers of NENs of unknown primary origin (UPO), a poor prognostic group with largely unmet clinical needs. In the absence of standard therapeutic algorithms, current guidelines suggest that the treatment of UPO-NENs should be based on tumor clinical-pathological characteristics, disease burden, and patient conditions. Chemotherapy represents the backbone for the treatment of high-grade poorly differentiated UPO-NENs, usually providing deep but short-lasting responses.

The only potential curative treatment is surgical resection. However, despite complex surgical procedures that have a remarkable risk of postoperative morbidity and mortality, the 5-year survival rate after radical surgery (R0) is 20-40% and recurrence rates are up to ~ 75%(4-6).

Background: High body mass index (BMI) plays a key role in the development of colon cancer (CC). Our post-hoc analysis from the TOSCA trial analyzed the association between BMI and survival outcomes in terms of relapse-free survival (RFS) and overall survival (OS) in stage II/III CC patients.
Patients And Methods: Patients enrolled in the TOSCA trial between 2007-2013 with BMI data entered the study.
Background: The optimal treatment strategy after first-line induction therapy in advanced HER2-positive oeso-gastric adenocarcinoma (OGA) remains challenging.
Methods: Patients treated with trastuzumab (T) plus platinum salts and fluoropyrimidine (F) as first-line chemotherapy between 2010 and 2020 for HER2-positive advanced OGA at 17 academic care centers in France, Italy, and Austria were included. The primary objective was the comparison of F + T vs T alone as maintenance regimen in terms of progression-free survival (PFS) and overall survival (OS) after a platinum-based chemotherapy induction + T.
Cholangiocarcinoma (CCA) is a heterogeneous group of neoplasms of the bile ducts and represents the second most common hepatic cancer after hepatocellular carcinoma; it is sub-classified as intrahepatic cholangiocarcinoma (iCCA) and extrahepatic cholangiocarcinoma (eCCA), the latter comprising both perihilar cholangiocarcinoma (pCCA or Klatskin tumor), and distal cholangiocarcinoma (dCCA). The global incidence of CCA has increased worldwide in recent decades. Chronic inflammation of biliary epithelium and bile stasis represent the main risk factors shared by all CCA sub-types.

Introduction: The combination of anti-EGFRs and doublet chemotherapy is considered the optimal upfront option for patients with RAS/BRAF wild-type left-sided metastatic colorectal cancer (mCRC). The prophylactic or reactive treatment with tetracyclines for EGFR inhibitor-induced skin toxicity is currently clinical practice, though non-conclusive results are available.
Methods: We performed a post hoc analysis of the Valentino study that randomized RAS wild-type mCRC patients to two panitumumab-based maintenance regimens after the first-line induction, aimed at assessing the safety and efficacy of the administration of a pre-emptive doxycycline prophylaxis for anti-EGFR-related skin toxicity.
Introduction: The Trust in Oncologist Scale (TiOS) is an 18-item questionnaire aimed to assess the cancer patients' trust in their oncologist and has been validated in Dutch and English language. This study aims to validate the Italian version of the TiOS (IT-TiOS) and the TiOS-Short Form (IT-TiOS-SF).
Methods: The IT-TiOS was administered to 194 patients recruited in an Italian oncology department from April to December 2018.

Background: Quality of life (QoL) patient-reported outcomes (PROs) data from pivotal first-line trials in metastatic colorectal cancer (mCRC) are poor. The Valentino study showed that de-escalation to single-agent panitumumab after 4-month induction with panitumumab-FOLFOX is inferior to panitumumab-5-FU/LV in patients with RAS wild-type mCRC, although slightly reducing toxicity. We report QoL, a secondary end-point.

It may be classified according to its anatomical location and distinguished in intrahepatic (iCCA), perihilar (pCCA), or distal (dCCA), each subtype implying distinct epidemiology, biology, prognosis, and strategy for clinical management. Its incidence has increased globally over the past few decades, and its mortality rate remains high due to both its biological aggressiveness and resistance to medical therapy.

Importance: Few studies are available on the role of maintenance strategies after induction treatment regimens based on anti-epidermal growth factor receptors, and the optimal regimen for an anti-epidermal growth factor receptors-based maintenance treatment in patients with RAS wild-type metastatic colorectal cancer is still to be defined.
Objective: To determine whether maintenance therapy with single-agent panitumumab was noninferior to panitumumab plus fluorouracil and leucovorin after a 4-month induction treatment regimen.
Design, Setting, And Participants: This open-label, randomized phase 2 noninferiority trial was conducted from July 7, 2015, through October 27, 2017, at multiple Italian centers.

Background: Platinum/fluoropyrimidine regimens are the backbone of first-line chemotherapy for advanced gastric cancer (AGC). However response rates to first line chemotherapy range from 30 to 50% and disease progression occurs after 4-6 cycles. The optimal duration of first-line therapy is still unknown and its continuation until disease progression represents the standard.

Objective: The RAMoss study aimed to evaluate the safety and efficacy profile of ramucirumab in the "real-life setting".
Patients And Methods: Patients from 25 Italian hospitals started therapy consisting of ramucirumab 8 mg/kg i.
Background: No prospective trials have specifically addressed the efficacy and safety of panitumumab in elderly patients with metastatic colorectal cancer (CRC). We aimed at assessing the efficacy and safety of single agent panitumumab in "frail" elderly patients diagnosed with metastatic RAS and BRAF wild-type CRC.
Materials And Methods: Forty elderly patients (aged ≥ 75 years) with metastatic RAS-BRAF wild-type CRC received off-label prescriptions of single-agent panitumumab at seven Italian institutions.
The treatment of renal cell carcinoma is rapidly changing as a result of recent evidence concerning the efficacy of biological drugs, antiangiogenetic agents and signal-transduction inhibitors. This paper will provide a critical overview of the use of immunotherapy in renal cell carcinoma and review the available data concerning the efficacy of interferons, interleukin-2 and other forms of immunological treatment, particularly allogenic transplantation and vaccines. Moreover, it will focus on the new mechanisms of regulation of the immune system with a better understanding of the interaction between host and tumor, the role of T regulatory cells, heat-shock proteins and vaccines.

Patients And Methods: Seventy-three eligible patients (median age, 73 years; range, 65 to 89 years) were enrolled. The first 30 patients received oral capecitabine 1,250 mg/m(2) twice daily on days 1 to 14 every 21 days.
It has been proposed that knowledge of estrogen receptor beta (ER-beta) expression may refine estrogen receptor alpha (ER-alpha) predictivity of response to endocrine therapy. We challenged this hypothesis in ER-alpha-positive breast cancers subjected to preoperative antiestrogen treatment. Forty-seven elderly (> or =65 years old) women with nonmetastatic, ER-alpha-positive (by immunohistochemistry) primary breast cancers (> 2 cm in diameter) entered a neoadjuvant hormone therapy protocol (60 mg/day toremifene for 3 months).

Today's challenge is the sequential use of AIs with different structure and no cross-resistance to improve the therapeutic outcome. The present study describes the biological action of the steroidal structure (SS)-AI exemestane (EXE), in patients progressing on aminoglutethimide (AG) or other non-steroidal structure (NSS)-AIs (letrozole or anastrozole).

A phase II study was conducted to assess the response rate and toxicity profile of pemetrexed, a novel multitargeted antifolate, in previously untreated patients with measurable, advanced, or metastatic adenocarcinoma of the stomach or gastroesophageal junction. In this study, pemetrexed-induced toxicity at the starting dose of 500 mg/m(2) intravenously once every 21 days was considerable with each of the first six patients who experienced at least one episode of grade 3/4 toxicity.
