Background: Basaloid squamous cell carcinoma (BSCC) is a high-grade variant of squamous cell carcinoma usually localized in the aerodigestive tract, with a poor prognosis. Surgical resection is generally recommended, even if no standard treatment has been established yet. Case Report: Here, we report the case history of a patient diagnosed with BSCC at the esophagogastric junction who was successfully treated with chemotherapy alone, leading to a durable complete response. Conclusions: The presented case illustrates the diagnostic challenges associated with BSCC of the esophagus and reports an unexpected chemosensitivity of this histotype to the combination of a platinum salt plus 5-fluorouracil, which could represent an optimal treatment strategy in unfit patients.

Extragonadal germ cell tumors (EGCTs) represent 1% to 5% of all germ cell tumors (GCTs) (1). Morphological type includes mature/immature teratoma, seminoma, yolk sac tumor, embryonal carcinoma, choriocarcinoma and mixed gonadal GCTs. Their anatomic distribution varies widely and includes the mediastinum, sacrococcygeal region, neck, retroperitoneum and other rare anatomic sites. Diagnosis of EGCTs is made on the basis of histological findings and excluding the presence of a testicular/ovarian involvement. Laboratory is pivotal for diagnosis of EGCTs, often demonstrating high levels of human chorionic gonadotropin (β-HCG) and/or α-fetoprotein (α-FP). The prognosis of patients with EGCTs is variable for the possible occurrence of aggressive behavior and distant metastasis (2). We describe computed tomography (CT) and magnetic resonance (MR) imaging findings of EGCTs reporting a case series of three male patients with different disease’s locations that underwent contrast-enhanced CT with or without positron emission tomography (PET) and/or MR examinations. The diagnostic workflow of all patients is also illustrated.

Guidelines on the treatment of metastatic squamous cell carcinoma of the penis are limited to a few prospective trials. Cisplatin-based regimens represent the standard of treatment with promising activity of taxanes. Recently, epidermal growth factor receptor overexpression has been shown in these patients. We treated an elderly man with a docetaxel-cetuximab combination after failure of the cisplatin regimen. We observed a necrosis of the inguinal lymph nodes and a reduction of (18)F-fluorodeoxyglucose uptake at PET/CT scan. Only mild mucositis and skin toxicity had been detected. Our case report, the first in the literature, shows that this combination is active and well tolerated in penile squamous cell carcinoma.

Background Previously published preliminary findings showed promising activity of paclitaxel in chemotherapy-pretreated metastatic penile cancer. Objective To evaluate the activity and safety of paclitaxel in pretreated metastatic penile cancer. Design, setting, and participants Twenty-five patients were enrolled in a single-arm phase 2 multicentre study and treated with 175mg/m 2 paclitaxel at 3-wk intervals until disease progression or irreversible toxicity. Measurements The objective response rate was the primary end point. Safety, progression-free survival (PFS), and overall survival (OS) were secondary end points. Results and limitations Partial responses were observed in 20% (5 of 25 patients). Grade 1–2 neutropenia, nausea, and oral mucositis were the most common side effects, noted in 13, 9, and 8 patients, respectively. Grade 3–4 neutropenia was reported in seven patients (28%). Median PFS was 11 wk (95% confidence interval [CI], 7–30); median OS was 23 wk (95% CI, 13–48). Median survival in responders was 32 wk (95% CI, 20–48). One limitation of our study was the limited accrual, which did not reach the target of 27 patients, due to the typical slow enrolment of a rare disease. Conclusions Final results of this study demonstrate that paclitaxel is moderately active and well tolerated. Further trials, which may also explore the combination of paclitaxel with other agents, are required to confirm our findings.

Thymic epithelial tumors (TETs) are rare tumors of the mediastinum, with an estimated incidence of about 3 cases per 100,000 inhabitants. Although anthracycline- and platinum-based chemotherapy is an active treatment for TETs, novel systemic therapeutic options are especially needed for metastatic disease, which is virtually incurable. On the basis of the radiographic response obtained with imatinib (Novartis Pharma, Basel, Switzerland) in a patient with thymic carcinoma harboring the V560del c-KIT mutation, a phase II trial was initiated at the Department of Molecular and Clinical Oncology and Endocrinology of University “Federico II of Naples” with the purpose to test imatinib in TETs. Imatinib was daily delivered at the dose of 400 mg to patients affected by TETs, who had progressed after at least one chemotherapy regimen. Positivity of c-KIT on immunohistochemistry was not mandatory for study entry. Radiographic responses were measured by CT scans performed every 3 months, according to the RECIST criteria. Toxicity was graded according to the Common Toxicity Criteria of the National Cancer Institute, version 3.0. Fifteen patients with advanced TETs were enrolled from March 2008 to May 2010. Three patients presented with thymic carcinomas. Two of these three patients presented c-kit expression on immunohistochemistry. No patient harbored a known c-kit activating mutation. Imatinib was very well tolerated, with no toxicity-related death. Diarrhea and migraine were the most frequent events, occurring both in 20% of patients, but were manageable and mild. No radiographic responses were recorded. Median progression-free survival was 3 months (interquartile range, 2.5–4). Median overall survival was not reached. The study was terminated before it reached its target accrual of 42 patients, because of the lack of responses and low accrual rate. This trial indicates the lack of effectiveness of imatinib in unselected patients with thymic epithelial tumors. Nevertheless, imatinib may represent a valuable option in selected patients with TETs, such as those harboring the V560del c-KIT mutation.

Digital ischemia is a rare paraneoplastic phenomenon associated with various malignancies, especially adenocarci-nomas. We reported a case of digital ischemia onset during treatment with capecitabine + oxaliplatin, letrozole and epoetin-beta in a 75-year old woman with colon and breast cancer and a secondary hepatic lesion. A literature review disclosed 68 cases of solid neoplasms associated with digital ischemia. The proposed mechanisms of such clinical manifestations are various: vasospasm due to sympathetic hyperactivity, arteritis induced by tumour antigen-antibody complexes deposition or as consequence of immune deregulation, blood hyperviscosity, hypercoagulability or peripheral thrombosis. In the present case, clinical and laboratory evaluations failed to reveal evidence of thrombosis, arteritis, inherited or acquired hypercoagulable state and we postulated the peripheral vasospasm and the sympathetic activity (possibly due to chemotherapy drugs) as potential causes of the digital ischemia.

Rationale: Paraneoplastic limbic encephalitis (PLE) is one of the most common causes of neurologic paraneoplastic syndromes, with unclear pathogenesis. While several reports published in the last decades showed the occurrence of PLE in a variety of cancers, only a few cases have been associated with colon cancer. Patient concerns: In February 2017, a 54-year-old man with clinical history of radically resected colon cancer started first line chemotherapy with FOLFOXIRI plus bevacizumab, after radiological diagnosis of multiple liver and bone metastases. During the third cycle of treatment, the patient developed psychomotor agitation and hallucinations followed by severe consciousness level reduction and cognitive impairment. Diagnoses: Magnetic resonance imaging showed hyperintense signals in both hippocampal areas, insula and right cingulate gyrus on fluid attenuated inversion recovery, diffusion weighted imaging, and T2-weighted images, highly suggestive of limbic encephalitis. Other causes (brain metastases, toxicity of chemotherapeutic agents, and infections) were excluded. Interventions: Empirical immunosuppressive treatment (high-dose immunoglobulins and corticosteroids) was administered and chemotherapy was resumed. Outcomes: A slowly progressive improvement in neurological condition has been observed, even though radiological signs of limbic encephalitis are still evident. Lessons: The present case highlights the complex diagnostic process of PLE, and the lack of a standard treatment. Moreover, the absence of correlation between PLE and tumor progression or tumor burden, and the opportunity of treating underlying neoplasm is discussed.

The prognostic role of drug-induced amenorrhea (DIA) was restrospectively evaluated in 221 out of 254 consecutive premenopausal patients treated with adjuvant CMF or a CMF-containing regimen; 33 patients were eliminated because of lack of menstrual data. All patients had metastatic axillary nodes; drug regimens were: CMF x 9 courses +/- Tamoxifen (TM) and CMF x 6 courses; median age was 43 (range 26-54). Premenopausal status was defined as last normal menses within the 6 weeks preceding initiation of chemotherapy: DIA as cessation of menses for at least 3 months not later than 3 months from the end of chemotherapy. DIA occurred in 166,221 (75.1%) patients and was strictly related to the age of the patients; also, the older the patients the shorter the time required to develop DIA. At median follow up of 69 months, Mantel-Byar analysis showed a longer disease free survival (DFS) for patients who developed DIA as compared with non amenorrheic women (P less than 0.001). DIA prognostic value was independent of age, number of involved nodes, tumour size and number of CMF cycles, as assessed by the Cox model (RH 0.43, 95% C.I. 0.24-0.77), in which DIA was entered as a time dependent covariate.

CEA, TPA, CA 15-3 were assayed in 238 patients in follow-up for breast cancer after surgery. CA 15-3 showed the best sensitivity and specificity; the predictive value of a positive CA 15-3 test was three times higher than CEA and TPA. No association was found between marker positivity and the number of organs involved by metastases. CA 15-3 positivity was significantly associated with visceral rather than soft tissue recurrences; no significant similar association was observed for CEA and TPA. CA 15-3 serum levels were early predictors of relapse in four out of nine patients within a 6-12 month follow-up period.

Aim of the study was to improve cure rate and survival of aggressive non-Hodgkin's lymphoma (NHL) with a tailored program of therapy based on histologic type, prognostic characteristics of patients and response to therapy, and with the use of differentiating or cytostatic agents such as Ara-C at low doses and alphaIFN. Fifty-four consecutive patients with aggressive NHL were treated in the induction phase with 4 sequential courses of a third generation regimen (modified CODBLAM IV), followed in responsive patients by 1 cycle of doxorubicin and cyclophosphamide and 1 cycle of high dose methotrexate with folinic acid rescue (AC-MTX). Patients who achieved partial response (PR) were treated with the combination of CCNU + vinblastine if affected by high grade NHL, or with low dose Ara-C plus alphaIFN if affected by intermediate grade NHL. Patients who obtained complete response (CR) with basal adverse prognostic factors were treated with alphaIFN as maintenance therapy for two years. Radiotherapy and surgery were effected in selected cases. Thirty-four patients (62.9%) achieved CR and 12 patients (22.2%) showed PR after induction therapy. Among the 12 patients who achieved PR, 6 prolonged CRs were obtained in 7 patients treated with Ara-C at low doses plus alphaIFN and 4 CRs were obtained in 5 patients treated with CCNU + vinblastine. After completion of treatment, 44 patients (81.5%) obtained CR, 2 patients (3.7%) showed PR and 8 patients (14.8%) presented progression of disease (PD). Fifteen patients received alphaIFN as maintenance therapy. The overall survival and failure-free survival rates are 53.7% and 50% respectively, with a median follow-up of 82 months: 27 patients remain alive, disease-free without relapses, and can be considered cured. This tailored program of therapy resulted effective and moderately toxic and may improve the outcome in aggressive NHL.

A phase II clinical trial of subcutaneous recombinant Interleukin 2 (rIL-2) given by 5 days pulses followed by a 9 days rest has been performed in patients affected by renal cell carcinoma, malignant melanoma and colorectal cancer. A total of 25 patients entered the study, completed at least six courses of treatment, and were evaluable for toxicity and response to treatment. This schedule of subcutaneous rIL-2 was well tolerated and no World Health Organization grade 3 side effects were observed. A 33.3% response rate was recorded in patients affected by renal cell carcinoma, although no major responses were achieved in patients with malignant melanoma and colorectal cancer. A durable increase of natural killer activity retained by poeripheral blood mononuclear cells was demonstrated in these patients and was paralleled by increased serum levels of interferon gamma and tumor necrosis factor a without changes of circulating interleukin-1d. It is concluded that this schedule of pulse administration of subcutaneous rIL-2 has antitumor activity in renal cell carcinoma and produces durable biomodulatory effects.

Forty-five patients with stage III-IV low grade non-Hodgkin's lymphoma (NHL) were treated with a non-intensive polychemotherapy regimen including chlorambucil-vincristine and cytarabine (Ara-C), termed COA, for a total of 366 courses, beginning in June 1986. Grade 4 myelotoxicity occurred in only 4/45 patients. No treatment related death was observed. All patients were evaluable for response. Overall, 38 (84%) objective responses, including 31 (69%) complete responses (CR), were observed. At a median follow-up of 57 (21-84+) months, only 8 deaths occurred. Twenty-seven (60%) patients are still disease-free. All disease-free patients were in their first CR. The seven-year estimated survival is 71% and the estimated 7-year progression-free survival (PFS) was 48%. The estimated probability of complete responders to be disease-free at 6 years is 78%. Pretreatment laboratory parameters (serum levels of thymidine kinase, LDH and TNF-alpha showed a good prognostic relevance at using univariate analysis. At multivariate analysis, only the pretreatment serum levels of TNF-alpha were significantly associated with a higher CR achievement probability (p = 0.02) and a longer PFS (p = 0.02). We established a risk model for clinical outcome based on these 3 parameters. Patients having all parameters within the normal range at diagnosis, showed a very good prognosis (100% 7-year PFS and survival), while patients with all parameters increased had a very poor prognosis (0% 7-year PFS and 22% 7-year survival). In conclusion, COA treatment appears to be a non-toxic and very effective treatment for low-grade non-Hodgkin's lymphomas.(ABSTRACT TRUNCATED AT 250 WORDS)

To evaluate retrospectively the efficacy of rituximab plus chemotherapy in gastric diffuse large B cell lymphoma (DLBCL).Sixty patients (median age: 58 years) with histologically confirmed gastric DLBCL treated at four Italian institutions between 2000 and 2007, were included in this analysis. Patients were selected by stage (I-IV, Lugano staging system), European Cooperative Oncology Group performance status (0-2) and treatment strategies. Treatment strategies were chemotherapy alone (group A, n = 30) [scheduled as cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) and CHOP-like], and chemotherapy combined with rituximab (group B, n = 30). The primary end point of the study was complete response (CR) rate; the secondary end points were disease-free survival (DFS) at 5 years and overall survival (OS).Median follow-up was 62 mo (range: 31-102 mo). We observed a significant difference between the two groups (A vs B) in terms of CR [76.6% (23/30) vs 100%, P = 0.04) and DFS at 5 years [73.3% (22/30) vs 100%, P = 0.03). To date, 19 group A (63.3%) patients are alive and 11 have died, while all group B patients are alive. No significant differences in toxicity were observed between the two groups.Rituximab in combination with chemotherapy improves CR rate, DFS and OS. Further prospective trials are needed to confirm our results.

Paraneoplastic sensitive neuropathy is one of the most common presentations among a group of cancer-related disorders known as Paraneoplastic Neurological Syndromes (PNS). PNS likely have an autoimmune etiology since they have been associated with the presence of antibodies against neuronal antigens expressed by tumor cells (such as anti-Hu, anti-Ri and anti-Yo). The tumors most frequently associated with PSN and onconeural antibodies are lung cancer, lymphomas and gynaecological tumors; however, they have also been described in other tumors. We report, for the first time, a case of neuroendocrine tumor of duodenum and PNS associated with anti-Hu antibodies. Moreover, we analyze and discuss the clinical implications that PNS and anti-Hu could have in patients with tumors.
