Phase II study of cabazitaxel as second-third line treatment in patients with metastatic adrenocortical carcinoma.

BACKGROUND: Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy with a poor prognosis. No efficacious treatment options are currently available for patients with advanced metastatic disease with disease progression to standard etoposide, doxorubicin, cisplatin and mitotane (EDP-M) therapy. We assessed the activity and tolerability of cabazitaxel as a second/third-line approach in metastatic ACC. PATIENTS AND METHODS: Patients included in this single-center, phase II study (ClinicalTrials.gov identifier NCT03257891) had disease progression to a cisplatin-containing regimen (such as EDP) plus mitotane, plus/minus a further chemotherapy line. Cabazitaxel was administered intravenously at 25 mg/m2 on day 1 of a 21-day cycle, for a maximum of six cycles. The primary endpoint was a disease control rate after 4 months. RESULTS: From March 2018 to September 2019, 25 eligible patients were enrolled. A disease control rate after 4 months was obtained in six patients (24%). No patients attained a disease response according to RECIST 1.1, 9 patients (36%) had stable disease and 16 patients (64%) progressive disease. Median progression-free survival and overall survival were 1.5 months (range 0.3-7 months) and 6 months (range 1-22.2 months), respectively. Cabazitaxel therapy was well tolerated and only three (12%) patients developed grade 3 toxicity which were nausea in one patient (4%) and anemia in two patients (8%). CONCLUSIONS: Cabazitaxel has a manageable toxicity profile but is poorly active as second/third-line treatment in advanced ACC patients. These results do not support further evaluation of cabazitaxel in this setting.

A multi-centre retrospective review of second-line therapy in advanced pancreatic adenocarcinoma.

INTRODUCTION: Limited information on second-line treatment in patients with pancreatic adenocarcinoma is available. At time of first-line treatment failure, approximately half of the patients are candidates for further treatment. MATERIAL AND METHODS: A retrospective review of 183 patients submitted to second-line therapy has been performed to identify prognostic factors, provides useful information for patients counseling and generates hypotheses for future studies. Inclusion criteria were: cytological or histologic diagnosis of pancreatic adenocarcinoma and prior gemcitabine-including chemotherapy. Any age, performance status (PS) and chemotherapy regimen were considered. RESULTS: One hundred and eighty-three patients (106 males; 168 metastatic; median age 62 years; median PS 1; 63 submitted to prior curative surgery, 32 to prior radiotherapy) with a median previous progression-free survival (PFS) of 6.7 months were included. Median and 6-month PFS after initiation of salvage therapy were 3.0 months and 20%. Median, 1 and 2 years, overall survival after initiation of salvage therapy were 6.2 months, 17 and 4%, respectively. Previous PFS, CA19.9 levels and age independently predicted OS. CONCLUSION: Re-challenge with gemcitabine and 5-fluorouracil administration may have a role in selected patients.

Targeted therapy with trastuzumab in dysplasia and adenocarcinoma arising in Barrett's esophagus: a translational approach.

AIM: Human epidermal growth factor receptor (HER2) protooncogene, overexpressed/ amplified in preneoplastic lesions and in adenocarcinoma (ADC) of the esophagus, can be considered a target for treatment of esophageal dysplasia/ADC. The aim of this study was to evaluate the therapeutic role of the anti-HER2 monoclonal antibody, trastuzumab, in the management of ADC originating from HER2-positive Barrett's esophagus (BE). METHODS: Two patients with high-grade dysplasia and ADC of the esophagus after esophageal mucosectomy and no metastatic disease were studied. Patients were not eligible for radical surgery or chemo-radiotherapy because of age and comorbidities. HER2 status was assessed by immunohistochemistry and fluorescence in situ hybridization. Additional immunohistochemical analyses were performed. The whole panel was analysed at baseline, after treatment and at follow-up. RESULTS: At baseline, the two patients showed HER-2 overexpression/amplification in all areas of dysplasia and ADC but not in BE. Six months after treatment no significant differences in terms of endoscopical and histological patterns of the disease were found. HER-2, EGFR, TOPOII-alpha and anti-ssDNA analysis demonstrated a down-regulation of these markers and increased apoptosis. CONCLUSION: This study demonstrates that this treatment is feasible. No clear evidence of dysplasia regression was observed. However, HER2 and TopoII-alpha downregulation and induction of apoptosis occurring 6 months after treatment encourages further investigation.

Merkel cell carcinoma and HIV infection: a case report and review of the literature.

Merkel cell carcinoma (MCC) is a skin cancer of neuroendocrine origin that occurs most often in sun-exposed areas. In the general population, it is a disease of older adults, with only 5% of cases occurring below the age of 50 years. Immunosuppression is the significant risk factor for the development of MCC and recently it was suggested that individuals with HIV have a relative risk of 13.4 to developed MCC in comparison with the general population. We report a case of MCC in an HIV-infected patient and we review nine patients with HIV with MCC. Our patient was a 54-year-old man who came to our attention without a known HIV diagnosis. He was apparently in good health and had no risk factor for HIV, but by the atypical site of the lesion and by the relative young age of the patient we suspected a case of immunosuppression and for this reason we did HIV test that had a positive result. The patient was treated with surgery and chemotherapy but died as a result of liver metastases 25 months after his tumor was diagnosed.

Psoriasis and tamoxifen therapy: a case report.

A case of chronic plaque psoriasis in a woman with advanced breast cancer is reported. Treatment of the breast cancer with tamoxifen cleared the psoriatic skin lesions for several months, even after suspension of the hormonal treatment.

Evaluating the impact of radiotherapy on the quality of life of cancer patients by two simple indexes. A pilot study.

The subjective chemotherapy impact (SCI) test has been widely used to evaluate the quality of life in patients receiving chemotherapy. In this study we have tested the SCI questionnaire as an index of the impact of radiotherapy on quality of life. A group of 25 consecutive cancer patients treated with radiotherapy in our centre were tested. In the first item patients were asked to state the number of days they spent with "discomfort". The second item asked them which days they would like to eliminate altogether because of the unbearable symptoms experienced. SCI questions were asked by the same physician before the start of radiotherapy, at the mid point, at the end and 4 months later. A preliminary assessment of validity and reliability of these two indexes provided satisfactory results; data allowed a clear and discriminating differentiation between patients treated with palliative curative radiotherapy and patients who received "adjuvant" treatment (radiotherapy worsened the quality of life in the latter group).

Solitary breast metastases from a renal cell carcinoma.

A case of solitary and metachronous breast metastases from a renal cell carcinoma is described nine years after surgery. The review of the literature proves that the breast is an unusual site for metastatic disease.
