This is one of the largest, single-centre, series of metastatic bpNETs. Among patients with metachronous metastases the pattern of recurrences was heterogeneous as were the follow-up exams used to detect them. The results of our analysis may represent solid bases for designing prospective clinical trials in homogeneous settings of bpNETs.

Significant progress has been achieved over the last decades in understanding the biology and mechanisms of tumor progression in urothelial carcinoma (UC). Although the therapeutic landscape has dramatically changed in recent years with the introduction of immune checkpoint inhibitors, advanced UC is still associated with rapidly progressing disease and poor survival. The increasing knowledge of the pathogenesis and molecular pathways underlying cancer development and progression is leading the introduction of target therapies, such as the recently approved FGFR inhibitor Erdafitinib, or the anti-nectin 4 antibody drug-conjugate Enfortumab vedotin. Antibody drug conjugates represent an innovative therapeutic approach that allows the combination of a tar get-specific monoclonal antibody covalently conjugated via a linker to a cytotoxic agent (payload). UC is a perfect candidate for this therapeutic approach since it is particularly enriched in antigen expression on its surface and each specific antigen can represent a potential therapeutic target. In this review we summarize the mechanism of action of ADCs, their applications in localized and metastatic UC, the main mechanisms of resistance, and future perspectives for their use in clinical practice.

The authors report a case of ischemic cardiopathy that occured during therapy with CDDP in a woman with an ovarian cancer which had been extensively pre-treated with adriamycin.

Lung neuroendocrine tumors (NETs) comprise typical (TC) and atypical carcinoids (AC). They represent the well differentiated (WD) or low/intermediate grade forms of lung neuroendocrine neoplasms (NENs). Unlike the lung poorly differentiated NENs, that are usually treated with chemotherapy, lung NETs can be managed with several different therapies, making a multidisciplinary interaction a key point. We critically discussed the multimodal clinical management of patients with advanced lung NETs. Provided that no therapeutic algorithm has been validate so far, each clinical case should be discussed within a NEN-dedicated multidisciplinary team. Among the systemic therapies available for metastatic lung NETs everolimus is the only approved drug, on the basis of the results of the phase III RADIANT-4 trial. Another phase III trial, the SPINET, is ongoing comparing lanreotide with placebo. Peptide receptor radionuclide therapy and chemotherapy were not studied within phase III trials for lung NETs, and they have been reported to be active within retrospective or phase II prospective studies. Temozolomide and oxaliplatin are two interesting chemotherapeutic agents in lung NETs. While some European Institutions were certificated as Centers of Excellence for gastroenteropancreatic NENs by the European Neuroendocrine Tumor Society (ENETS), an equivalent ENETS certification for lung NENs does not exist yet. Ideally a lung NEN-dedicated multidisciplinary tumor board should include NEN-dedicated medical oncologists, thoracic medical oncologist, thoracic surgeons, pathologists, interventional radiologists, endocrinologists, radiotherapists, interventional pneumologists, nuclear physician.

Non-muscle-invasive bladder cancer (NMIBC) is characterized by a high rate of cure, but also by a non-negligible probability of recurrence and risk progression to muscle-invasive disease. NMIBC management requires a proper local resection and staging, followed by a risk-based treatment with intravesical agents. For many years, the current gold standard treatment for patients with intermediate or high-risk disease is transurethral resection of the bladder (TURB) followed by intravesical bacillus Calmette–Guérin (BCG) instillations. Unfortunately, in about half of high-risk patients, intravesical BCG treatment fails and NMIBC persists or recurs early. While radical cystectomy remains the gold standard for these patients, new therapeutic targets are being individuated and studied. Radical cystectomy in fact can provide an excellent long-term disease control, but can deeply interfere with quality of life. In particular, the enhanced immune checkpoints expression shown in BCG-unresponsive patients and the activity of immune checkpoints inhibitors (ICIs) in advanced bladder cancer provided the rationale for testing ICIs in NMIBC. Recently, pembrolizumab has shown promising activity in BCG-unresponsive NMIBC patients, obtaining FDA approval. Meanwhile multiple novel drugs with alternative mechanisms of action have proven to be safe and effective in NMIBC treatment and others are under investigation. The aim of this review is to analyse and describe the clinical activity of new emerging drugs in BCG-unresponsive NMIBC focusing on immunotherapy results.

We describe a patient with acute B-lymphocyte lymphoblastic leukemia who developed laboratory changes (not detectable free thyroxine, TSH 66 microIU/ml) suggesting severe primary hypothyroidism. Histological examination at autopsy showed massive leukemic infiltration of the thyroid gland: the progressive reduction of thyroid hormone levels with concomitant increase in TSH levels observed over a three-month period from the onset of the hemopathy suggests a cause-effect relationship between leukemic infiltration of the thyroid gland and hypothyroidism.
