Eighty-four patients with advanced NSCLC who underwent F-FDG PET/CT before therapy were retrospectively studied. SUVmax, SUVmean, CoV, total Metabolic Tumor Volume (MTV) and whole-body Total Lesion Glycolysis (TLG) were determined by an automated contouring program (SUV threshold at 2.

Type 2 Deiodinase Thr92Ala Polymorphism and Aging Are Associated with a Decreased Pituitary Sensitivity to Thyroid Hormone.

The DIO2 Thr92Ala polymorphism (rs225014), which occurs in about 15-30% of Caucasian people, determines a less efficient type 2 deiodinase (D2) enzyme. The aim of this study was to determine the impact of DIO2 Thr92Ala polymorphism on the serum thyrotropin (TSH) levels in thyroidectomized patients with hypothyroidism and to evaluate whether TSH levels and aging could be related, at pituitary level, to D2 activity. This prospective study was performed on 145 thyroid cancer patients, treated with total thyroidectomy, and undergoing radioiodine treatment after 3 weeks of levothyroxine (LT4) withdrawal.

The unusual first sign of presentation of renal cell carcinoma: a rare case report.

Background: Renal cell carcinoma (RCC) usually is characterized by a slow pattern of growth, although with an unpredictable evolution and metastatic potential, favored by its extensive vascularity and related high angioinvasive profile. The most common sites of metastases from kidney cancer are lung, lymph nodes, bone and liver; whereas orbital metastases are very uncommon. In more than 25% of cases, orbital metastases are the first manifestation of a primary tumor of unknown origin.

Combination of Lenvatinib and Pembrolizumab as Salvage Treatment for Paucicellular Variant of Anaplastic Thyroid Cancer: A Case Report.

Anaplastic thyroid cancer (ATC) is a rare but aggressive thyroid cancer, responsible for about 50% of all thyroid cancer-related deaths. During the last two decades, the development of a multimodal personalized approach resulted in an increased survival. Here, we present an unusual case of a 54-year old woman with a paucicellular metastatic ATC, a rare variant of ATC, who was treated with a combination of surgery, radiation therapy and cytotoxic chemotherapy.

Higher baseline TSH levels predict early hypothyroidism during cancer immunotherapy.

Background And Purpose: Immune checkpoint inhibitors (ICIs) are monoclonal antibodies that enhance the immune response against cancer cells. ICIs are generally well tolerated, although endocrine immune-related adverse events (irAEs) are common. We investigated the risk factors for thyroid irAEs in patients treated with ICIs.

Brain Metastases Unresponsive to Immunotherapy Detected by 18F-FDG-PET/CT in a Patient with Melanoma.

Recently, newer therapies such as immunotherapy have been increasingly used in the treatment of several tumors, including advanced melanoma. In particular, several studies showed that the combination of ipilimumab, an anti-Cytotoxic T-lymphocyte Associated Protein 4 (CTLA-4) monoclonal antibody and nivolumab, an anti-Programmed Death 1 (PD-1) monoclonal antibody, leads to improved survival in patients with metastatic melanoma. Despite that, immunotherapeutic agents may not reach therapeutic concentration in the brain due to the blood-brain barrier.

Total metabolic tumor volume by 18F-FDG PET/CT for the prediction of outcome in patients with non-small cell lung cancer.

Objective: Metabolic tumor volume (MTV) and total lesion glycolysis (TLG) are imaging parameters derived from 18F-FDG PET/CT that have been proposed for risk stratification of cancer patients. The aim of our study was to test whether these whole-body volumetric imaging parameters may predict outcome in patients with non-small cell lung cancer (NSCLC).

Methods: Sixty-five patients (45 men, 20 women; mean age ± SD, 65 ± 12 years), with histologically proven NSCLC who had undergone 18F-FDG PET/CT scan before any therapy, were included in the study.

Systemic treatment of malignant gastrointestinal neuroectodermal tumour after childhood neuroblastoma: chemotherapy in malignant gastrointestinal neuroectodermal tumour.

Malignant gastrointestinal neuroectodermal tumour is an extremely rare neoplasm that arises in the wall of the small bowel, stomach or large bowel in young-aged and middle-aged adults. Histologically, it is generally characterized by monomorphic cells with clear cytoplasma, S-100 protein expression, and EWSR1 gene translocation. To the best of our knowledge, we describe for the first time, the case of a young woman with a diagnosis of metastatic gastrointestinal neuroectodermal tumour arising from ileum, who had a childhood adrenal neuroblastoma with liver, bone and lymph nodes metastasis, treated with four cycles of chemotherapy with the schedule CADO-CVP (CADO: cyclophosphamide 300 mg/m/day on days 1-5, vincristine 1,5 mg/m/day on days 1 and 5, and doxorubicin 60 mg/m/day on day 5; CVP: cisplatin 40 mg/m/day on days 1-5 and etoposide 100 mg/m/day on days 1-5) followed by right adrenal, kidney, lymph nodes and liver lesion resection, conditioning chemotherapy (melphalan-carmustine-teniposide), stem cells autologous transplantation and consecutively radiotherapy on the spine (T9 to L3) for a total of 30 Gy.

A case report of limbic encephalitis in a metastatic colon cancer patient during first-line bevacizumab-combined chemotherapy.

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.

Preventing Venous Thromboembolism in Ambulatory Cancer Patients: The ONKOTEV Study.

Background: The efficacy of risk model scores to predict venous thromboembolism (VTE) in ambulatory cancer patients is under investigation, aiming to stratify on an individual risk basis the subset of the cancer population that could mostly benefit from primary thromboprophylaxis.

Materials And Methods: We prospectively assessed 843 patients with active cancers, collecting clinical and laboratory data. We screened all the patients with a duplex ultrasound (B-mode imaging and Doppler waveform analysis) of the upper and lower limbs to evaluate the right incidence of VTE (both asymptomatic and symptomatic).

Basaloid squamous cell carcinoma: a rare tumor at the esophagogastric junction and an unexpected durable complete response to FOLFOX-4.

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.

FOLFIRI in patients with locally advanced or metastatic pancreatic or biliary tract carcinoma: a monoinstitutional experience.

Pancreatic and biliary tract carcinomas are very chemoresistant. After a first-line treatment with a gemcitabine-based regimen, no second-line scheme is consolidated in clinical practice. The aim of this study was to evaluate the toxicity and the activity of the FOLFIRI regimen as first-line or second-line chemotherapy in patients with pancreatic or biliary tract tumors.

Non-AIDS-related Kaposi's sarcoma: A single-institution experience.

Aim: To evaluate the outcomes and potential prognostic factors in patients with non-acquired immunodeficiency syndrome (AIDS)-related Kaposi's sarcoma (KS).

Methods: Patients with histologically proven non-AIDS-related KS treated with systemic chemotherapy were included in this retrospective analysis. In some cases, the human herpes virus 8 status was assessed by immunohistochemistry.

Tumor-to-tumor metastasis: breast cancer metastatic to thymic epithelial tumor.

Tumor-to-tumor metastasis is a rare phenomenon, with around 150 cases being reported in the literature. Breast cancer is the second most commonly reported donor tumor after lung cancer, but thymic epithelial tumors have never been reported as recipient tumors. Furthermore, the thymus is rarely affected by metastases.

EMPACT syndrome associated with phenobarbital.

Intracranial malignancies can be complicated by seizure activity, and anticonvulsants such as phenytoin are usually administered to prevent this neurological kind of complication. Cranial radiation therapy is instead the treatment of choice when the tumor is unresectable. Anyway, the combination of phenytoin and cranial radiation therapy can lead to a rare and severe mucocutaneous complication called EMPACT syndrome.

Signet-ring-cell carcinoma of stomach metastatic to the bladder: a case report with cytological and histological correlation and literature review.

Background: Bladder involvement by a secondary tumor is fairly rare and an uncommon source of bladder metastasis is the stomach.

Case Report: The authors report a case of a 38-year-old man with a bladder metastasis from a gastric signet-ring-cell (SRC) adenocarcinoma who presented with ematuria. The clinical history and the presence of SRCs in the voided urinary cytology and histologically in the suburothelial connective, with an overlying intact urothelium suggested a diagnosis of bladder metastasis from gastric carcinoma.

Combination of docetaxel and cetuximab for penile cancer: a case report and literature review.

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.

Triplets versus doublets, with or without cisplatin, in the first-line treatment of stage IIIB-IV non-small cell lung cancer (NSCLC) patients: a multicenter randomised factorial trial (FAST).

Background: The FAST is a 2 × 2 factorial trial addressing two questions: (1) the role of replacing cisplatin (P) with a non-platinum agent, vinorelbine (N), and (2) the role of adding a third agent, ifosfamide (I), in a doublet based on gemcitabine (G).

Methods: A total of 433 stage IIIB-IV non-small cell lung cancer (NSCLC) patients were randomised to one of four arms: gemcitabine-cisplatin (GP), gemcitabine-vinorelbine, gemcitabine-ifosfamide-cisplatin or gemcitabine-ifosfamide-vinorelbine. Two comparisons were performed: N- vs P-containing regimens and I-triplets vs non-I doublets.
